In order to solve the problem of reservoir inferior separating effect in prior art, the invention provides a kind of reservoir and compressor, wherein, the reservoir that compressor comprises compressor body 60 and is connected with compressor body 60, reservoir is above-mentioned reservoir.
As shown in Figures 2 and 3, reservoir comprise housing 10, blast pipe 20 and only for by the liquid guide flow in housing 10 to the reflux assembly 50 of blast pipe 20, when reservoir is in using state, housing 10 has the upper end 11 and lower end 12 that are oppositely arranged; A part for blast pipe 20 stretches in housing 10; Reflux assembly 50 is connected with blast pipe 20, and reflux assembly 50 has the construction of switch for controlling reflux assembly 50 and blast pipe 20 conducting or cut-off.
By arranging reflux assembly 50 in reservoir, and make reflux assembly 50 only for by the liquid guide flow in housing 10 in blast pipe 20, and the water conservancy diversion opportunity of liquid is controlled by construction of switch, effectively to avoid gas backstreaming in blast pipe 20 in housing 10, thus liquid gas is fully separated by reservoir, improve the separating effect of reservoir, and then improve the performance of compressor.
In the embodiment shown in Fig. 2 and Fig. 3, reflux assembly 50 is at least partially positioned at housing 10.The overall volume of reservoir can be reduced like this, effectively utilize the space in housing 10, contribute to the Miniaturization Design of compressor.
Certainly, reflux assembly 50 can also be arranged on the outside of housing 10, only needs to ensure reflux assembly 50 and the fluid communication in housing 10.
In order to improve the liquid gas separating effect of reservoir, the upper end 11 that the mouth of pipe being positioned at the first end of housing 10 of blast pipe 20 deviates from housing 10 is arranged.Gas after the abundant liquid gas of reservoir is separated, then can be derived through blast pipe 20 by the blast pipe 20 arranged as aforesaid way, thus effectively avoids the liquid be not fully separated to be mixed in blast pipe 20, improves the liquid gas separating effect of reservoir.
In the embodiment shown in Fig. 2 and Fig. 3, the mouth of pipe of the first end of blast pipe 20 is arranged towards the lower end 12 of housing 10.The blast pipe 20 of such setting can effectively avoid liquid to be mixed in it.
Certainly, the mouth of pipe of the first end of blast pipe 20 can also towards having a down dip or being horizontally disposed with.
Alternatively, the part being positioned at housing 10 of blast pipe 20 takes the shape of the letter U.
Reservoir in the present invention also comprises filter screen 30, and filter screen 30 is arranged in blast pipe 20.The filter screen 30 arranged in blast pipe 20 can ensure the liquid gas separating effect of reservoir.
As shown in Figures 2 and 3, the mouth of pipe place being positioned at the first end of housing 10 of blast pipe 20 is provided with filter screen 30.Like this, can enter in blast pipe 20 by barrier liquid within the very first time, improve the liquid gas separative efficiency of reservoir.
Reservoir in the present invention also comprises liquid storage baffle plate 40, liquid storage baffle plate 40 is arranged in housing 10 the cavity of housing 10 to be separated into two sub-cavitys 13 of relatively isolating, two sub-cavitys 13 set gradually along the upper end 11 of housing 10 to the direction of lower end 12, and the first end of blast pipe 20 is positioned at the sub-cavity 13 of the side, lower end 12 away from housing 10.Owing to being provided with liquid storage baffle plate 40, thus can raise the liquid level of liquid in housing 10, be convenient to reflux assembly 50 and carry out liquid guide flow.
As shown in Figures 2 and 3, the circumferential edge of liquid storage baffle plate 40 has bending flange 41, and bending flange 41 is towards upper end 11 bending of housing 10.The liquid storage baffle plate 40 of said structure effectively can converge liquid.
Certainly, liquid storage baffle plate 40 can also be a flat board suitable with the inwall of housing 10, does not namely have bending flange 41.
In the embodiment shown in Fig. 2 and Fig. 3, reflux assembly 50 comprises valve body 51, discharging tube 52, piston 53 and reposition element 54, and valve body 51 has discharge opeing intercommunicating pore 511, valve body 51 at least partially with the fluid connection in housing 10; The first end of discharging tube 52 is communicated with discharge opeing intercommunicating pore 511, and the second end of discharging tube 52 is communicated with blast pipe 20; Piston 53 is construction of switch, and piston 53 to be arranged in valve body 51 with shutoff movably or to dodge discharge opeing intercommunicating pore 511; Reposition element 54 abuts with piston 53.
After liquid vapour mixture enters reservoir, liquid gas completes liquid gas and is separated at filter screen 30 place of blast pipe 20, gas directly enters in the cavity of compressor body 60 by blast pipe 20; Liquid then accumulates in liquid storage baffle plate 40 place, after liquid acquires a certain degree, due to Action of Gravity Field, liquid can press down piston 53 and move down to make piston 53, and discharge opeing intercommunicating pore 511 is opened, now discharge opeing intercommunicating pore 511 is communicated with blast pipe 20 by discharging tube 52, and liquid is then by valve body 51, discharge opeing intercommunicating pore 511, discharging tube 52, blast pipe 20 and flowing in the cavity of compressor body 60.
As shown in Figures 2 and 3, the sub-cavity 13 being positioned at the side, upper end 11 away from housing 10 at least partially of valve body 51.Like this, make the top liquid collecting of liquid storage baffle plate 40, reflux assembly 50 is installed in bottom, thus improves the arrangement reasonability of each parts in reservoir.
In the embodiment shown in Figure 2, discharging tube 52 is positioned at the sub-cavity 13 of the side, upper end 11 away from housing 10.Like this, the parts being exposed to housing 10 outside are minimum, can effectively avoid external force to the impact of discharging tube 52, the dependability that improve reservoir, the service life extending reservoir, reduce its spoilage.
In the embodiment shown in Figure 2, valve body 51 has flowing hole 512, and flowing hole 512 is communicated with the sub-cavity 13 of the side, lower end 12 away from housing 10.Due to valve body 51 being provided with flowing hole 512, the liquid thus in housing 10 can easily enter in valve body 51 from flowing hole 512, thus ensures that reflux assembly 50 can smoothly by the guiding fluid blast pipe 20 in housing 10.
In the embodiment shown in fig. 3, discharging tube 52 is protruding by housing 10.Compared with the embodiment shown in Fig. 2, the mode that this discharging tube 52 is external, has advantage easy to maintenance.
In the embodiment shown in fig. 3, valve body 51 is substantially all in the sub-cavity 13 of downside, but valve body 51 still with the fluid connection on the top of liquid storage baffle plate 40, to ensure the water conservancy diversion reliability of liquid.
In the embodiment shown in fig. 3, reflux assembly 50 also comprises mozzle 55, and the two ends of mozzle 55 are all communicated with valve body 51, and the two ends of mozzle 55 two tie points on valve body 51 are arranged along the upper end 11 of housing 10 to the interval, direction of lower end 12.When piston 53 moves down, the mouth of pipe elder generation being positioned at upside of mozzle 55 and fluid connection, now liquid directly can flow to the downside mouth of pipe of mozzle 55 by this mozzle 55, and is directly discharged by discharging tube 52.
In a not shown detailed description of the invention, reflux assembly 50 can also be ball-and-seat, to ensure being only guiding fluid blast pipe 20 side by housing 10.
Reservoir in the present invention eliminates diaphragm structure, thus it is more smooth and easy that the gas in housing is flowed, and also has good effect to the greasy property improved in compressor body and runnability.
