[0015] The intelligent control refers to that when the user uses the wall-mounted pipeline to heat the water bag machine, there is no complicated control program to operate, and the machine can be used arbitrarily according to the daily use of the user. The random and convenient mode of operation is due to the fact that the rapid heating system (001) uses the dehydration relief valve (12) and the delay switch (29) to complement each other.

[0016] The dredging pressure reducing valve (12) is composed of a three-way upper valve body (1201), a ball seat (1202), a valve ball (1203), a valve spring (1204), and a lower valve body (1205).

[0040] The present invention will be described in detail below with reference to the accompanying drawings -

[0041] As shown in FIGS. 1 and 2, a wall-mounted pipeline heating bag water machine can be divided into two parts, namely a water supply part and a heating part.

[0042] As shown in FIG. 1 and 2, the water supply part includes: a cover (1) on the cover (1), a hook (3), a water bag (4), a water outlet valve (5), and a water intake head ( 6), a switch tube (7), a fixed nut (8), a water supply pipe (9), a tank interface (10), characterized in that: the water bag (4) is vertically placed as a water tank In the upper body (2), when the water bag (4) is placed, the water head (6) will pierce the water bag (4), and the drinking water passes through the water head (6), the water supply pipe (9), and the check valve ( 19), rapid heating system The system (001) water supply; the outlet valve (5), compatible with the cold and hot water switch function, serves as a two-valve task. This is because the instant boiling heating system (001) is not in the normal state. What needs to be heated by electricity is water at normal temperature. At this time, the so-called cold drinking water can be obtained by opening the water outlet valve (5).

[0043] As shown in FIG. 1 and 2, the heating part is composed of a water outlet valve (5), a water supply pipe (9), a cold water tee (16), a boiling water pipe (13), and a desuperheating pressure reducing valve (12). ), thermostat (14), boiling water tee (11), connecting pipe (18), check valve (19), electric heating film quartz heating pipe (21), water supply pipe (23) and water inlet (25) .

[0044] As shown in FIG. 1 and 2, the cold water tee (16) turns on the water supply pipe (9), receives the water supply pipe (9) water supply, and the drinking water enters the water supply pipe (23) via the check valve (i9). The water supply pipe (23) is connected to the water inlet (25) of the electrothermal film quartz heat pipe (21), and enters the electric heating film quartz heat pipe (21) which is connected in series by the communication pipe (18) into an "S" shape. Port, accepting the heating system of the rapid heating (001) "fire-filled water", drinking water after three-stage heating, flowing through the upper port of the electrothermal film quartz heating tube (21) in the "S" shape, drinking water It is already in a boiling state, and the boiled drinking water is ejected from the water outlet valve (5) through the boiling water pipe (13) and the boiling water tee (11).

[0045] As shown in FIG. 1 and 2, the device of the control system is composed of a desuperheating pressure reducing valve (12), a thermostat (14), a check valve (19), a circuit board (26), and a delay. The time switch (29) is combined.

[0046] As shown in FIG. 1 and 2, the function of the dredging pressure reducing valve (12) is that when the drinking water is boiled, the delay circuit is still in the working state and the outlet valve (5) is closed, the rapid heating is performed. The pressure generated by the system (001) can be released through the sluice relief valve (12) for safe heating.

[0047] In other words, if the machine is still in the heating condition and the user draws water less than 350ID1, the user is allowed to close the outlet valve (5) to stop the water outlet, because the outlet valve (5) is closed at the same time. The dredging pressure reducing valve (12) will start to operate, and the pressure generated by the rapid heating system (001) will open the valve ball (1203) in the dredging pressure reducing valve (12) to discharge the high pressure gas and water back to the water supply. In tube (9). Therefore, the application of the dewatering pressure reducing valve (12) allows the user to freely obtain the required amount of water, which greatly improves the freedom of operation of the machine. The user can directly close the outlet valve (5) with a water intake of 350 ml. When a large amount of boiling water is obtained, it is only necessary to start the delay switch (29) again.

[0048] As shown in FIG. 3, the dredging pressure reducing valve (12) is composed of a three-way upper body (1201), a ball seat (1202), a valve ball (1203), and a spring (1204). And a lower valve body (1205), the upper valve body (1201) and the lower valve body (1205) are screwed to form a valve body cavity, and the upper valve body (1201) acts as a valve ball seat (1202) of the valve ball (1203), The valve spring (1204) presses the valve ball (1203) onto the ball seat (1202).

[0049] As shown in FIG. 3, the dredging pressure reducing valve (12) is installed in parallel on the pipeline between the boiling water pipe (13) and the water supply pipe (9) so as to close the water outlet valve (5). In the case, the high-pressure water and gas are discharged back into the water supply pipe (9); the upper valve body (201) of the dewatering and decompression reading (12) is a three-way port and the boiling water pipe (13) Connected, the other port of the boiling water tee (11) is connected to the outlet valve (5); the lower port of the decanting pressure reducing valve (12> and the upper valve of the three-way type in the check valve (19) Body (301) When the phase is connected, when the drinking water is boiling and the delay circuit is still working, but the outlet valve (5) is closed, the high-pressure water generated by the rapid heating system (001) will open the diverting pressure reducing valve ( The ball (1203) in the 12) discharges the high-pressure water and gas back into the water supply pipe (9) for safe heating.

[0050] As shown in FIG. 3, the check valve (19) is composed of a three-way upper valve body (1901), a closed U (1902), a valve flap root (103), a circular valve flap (1904), and The lower valve body (1905) is composed of the upper valve body (1901) and the lower valve body (1905), forming a valve cavity of the check valve (19), wherein the valve chamber is provided with a soft The circular valve flap (1904), the round valve (1904) and the valve stem root (1903) have an L-shaped structure, and the circular valve flap (1904) and the valve flap root (1903) are integrally formed, and the valve stem root (1903) is buried. Planted in a preset groove of the upper valve body (i90i) and the lower valve body (1905) screwing portion; the check valve (19) is connected in series with the water supply pipe (23), and has the function of controlling drinking water only. Out of the function; to enable drinking water to achieve heating in a closed environment.

[0051] The thermostat (14) as shown in FIG. 2 is connected in series to the zero line of the main circuit, and is disposed at the boiling water outlet of the electrothermal film quartz heating tube (21) of the "S" type series. The temperature of the open circuit set by the thermostat (14) is 105*C. When the surface temperature of the electrothermal film quartz heating tube (21) exceeds 105T:, or the machine is dry, the bimetal in the thermostat (14) The separation principle is generated due to the difference in thermal expansion coefficient, which automatically cuts off the circuit and protects the safe operation of the machine.

[0052] As shown in FIG. 2, the functions and principles of the delay switch (29) and the circuit board (26) are: The drinking machine is connected to the power supply in the standby state, and the 220V main power is rectified by the Dl-D4. R2 voltage limiting current limit, C 3 filtering, to obtain DC working voltage. Then, after R4 current limit, VT1 is turned on by the base bias current, and the trigger current of the unidirectional thyristor SCR is shorted to ground by VT1. Since the SCR has no trigger current, the main circuit is in the off state, and the machine does not work. When the drinking machine is heated, while the delay switch (29) is pressed, the electrolytic capacitor C 2 is charged, and VT2 is turned on by the base bias current. At this time, the base bias current of VT1 is short-circuited by VT2 to the ground. VT1 is turned off due to loss of the base bias current, the SCR trigger terminal is turned on and the drinker starts to work; when the delay switch (29) is released, the base bias current of VT2 is turned off again, but At this time, due to the presence of the charging voltage on C 2 , the base bias current of VT2 can still be maintained through R5, VT2 is turned on, VT1 is turned off, SCR continues to be turned on, and the drinking machine is constantly operated, when the charging voltage is on C 2 After the release is completed, when VT2 has no base bias current and is turned off, VT21 is turned on, SCR turns off the main circuit, and the machine stops.

[0053] As shown in FIG. 2, the circuit board (26) of the delay switch circuit is installed in a special mounting groove below the protection box (15) to avoid the influence of high temperature on the circuit.

[0054] Further, the delay time of the delay switch circuit is 60 seconds. During this period, the boiling water output by the drinking machine is not less than 350 ml. However, the user's water consumption may not be exactly 350ml, and the amount greater than or less than 350ml is objectively present. The following two conditions are described as follows -

[0055] In the first case, when the amount of the user is less than 350 ml, it is allowed to immediately close the outlet valve (5). Since the dredging pressure reducing valve (12) provided in the machine starts the β water line while closing the water outlet valve (5), the boiling water is discharged back into the water supply pipe (9) of the drinking machine. In this way, although the machine works for a few seconds, it is in exchange for the safe operation of the drinker and the user's convenient use. [0056] In another case, if a group of guests or boiling water needs more than 350ml, the drinking machine will automatically stop after 60 seconds of work, in this case, the user only needs to start again. Easy work on the delay switch (29) is fine.
