[0002] At present, in order to realize multiple modes of operation of the compressor, it is necessary to add components. For example, the air-injection and heat-increasing operation and independent compression operation of the compressor both require the connection of an additional liquid distributor to the system flash evaporator or heat exchanger.

This requires the addition of a liquid distributor connected to the air source to supply refrigerant to the compressor. However, realizing the air-injection and heat-increasing operation and independent compression operation of the compressor by adding components such as a liquid distributor will reduce the reliability of the compressor and increase the assembly requirements of the compressor, which is not conducive to improving the assembly efficiency of the compressor.

[0021] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0022] The purpose of this specific embodiment is to provide a liquid distributor, which can realize multi-mode operation of the compressor by controlling the opening and closing states of the air inlet and air supply port of the exhaust pipe through the control part on the exhaust pipe, without the need for additional components. This solves the problem in the prior art that the multi-mode operation of the compressor requires additional components, resulting in low reliability and assembly efficiency of the compressor.

[0023] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention described in the claims. In addition, the entire contents of the configurations shown in the following embodiments are not limited to the solutions required as the invention described in the claims.

[0024] See also Figure 1 and Figure 2 The present invention provides a liquid dispenser, comprising a cylinder 1, an air inlet pipe 3 and an exhaust pipe 4 arranged on the cylinder 1, wherein the exhaust pipe 4 is provided with at least one and is connected to the cylinder of the compressor in a one-to-one correspondence, and each exhaust pipe 4 is provided with an air inlet 5 communicating with the chamber 2 inside the cylinder 1. At least one exhaust pipe 4 is also provided with an air replenishment port 6 and a control member, wherein the air replenishment port 6 is connected to an air replenishment source, and the control member is used to control the opening and closing of the air inlet port 5 of the exhaust pipe 4, and the opening and closing of the air replenishment port 6.

[0025] When the control component controls the air inlet 5 to be opened and the air supply port 6 to be closed, the refrigerant gas in the chamber 2 enters the cylinder through the exhaust pipe 4 for compression, and the cylinder connected to the exhaust pipe 4 is in a normal operation mode. When the control component controls the air supply port 6 to be opened and the air inlet 5 to be closed, the refrigerant gas provided by the air supply source enters the cylinder through the exhaust pipe 4 for compression, and the cylinder corresponding to the exhaust pipe 4 only compresses the refrigerant gas provided by the air supply source, and the cylinder is in an independent compression operation mode. When the control component controls the air supply port 6 and the air inlet 5 to be both in an open state, the refrigerant gas in the chamber 2 and the refrigerant gas provided by the air supply source both flow into the cylinder from the exhaust pipe 4 for compression, and the cylinder corresponding to the exhaust pipe 4 is in an air supply enthalpy increase operation mode.

[0026] With such arrangement, the multi-mode operation of the compressor is controlled by the liquid distributor. The control component arranged in the exhaust pipe controls the opening and closing states of the air inlet 5 and the air supply port 6 to realize the multi-mode operation of the compressor. There is no need to add additional components such as liquid distributors. The overall structure of the compressor is simple and easy to assemble, which improves the assembly efficiency of the compressor.

[0027] In the case where the compressor has one cylinder, the liquid distributor has an exhaust pipe 4, which is connected to the cylinder of the compressor, and is provided with an air inlet 5 and an air supply port 6, and a control element for controlling the opening and closing of the air inlet 5 and the air supply port 6. When the control element controls the air inlet 5 to be closed and the air supply port 6 to be opened, the compressor is in an independent operation state; when the control element controls the air inlet 5 to be opened and the air supply port 6 to be closed, the compressor is in a normal operation mode; when the control element controls the air inlet 5 and the air supply port 6 to be opened, the compressor is in an air supply enthalpy increase operation mode.

[0028] The following is a specific description of the various operating modes of the compressor using an example of a compressor having two cylinders, wherein the two cylinders of the compressor are an upper cylinder and a lower cylinder. In the case where only one exhaust pipe 4 is provided with an air supply port 6 and a control component, the exhaust pipe 4 can be connected to the upper cylinder or the lower cylinder. Next, the connection between the exhaust pipe 4 provided with an air supply port 6 and a control component and the lower cylinder is used as an example for description, and the exhaust pipe 4 connected to the upper cylinder is not provided with an air supply port 6 and a control component. The upper cylinder is in a normal operating state, and the compressed gas is the refrigerant gas flowing from the evaporator into the cylinder 1. The lower cylinder has the following operating modes: when the control component controls the air inlet 5 of the exhaust pipe 4 to open and the air supply port 6 to close, the refrigerant gas in the chamber 2 enters the lower cylinder through the exhaust pipe 4 for compression, and the lower cylinder is in a normal operating mode; when the control component controls the air supply port 6 to open and the air inlet 5 to close, the refrigerant gas provided by the air supply source enters the lower cylinder through the exhaust pipe 4 for compression, and the lower cylinder only compresses the refrigerant gas provided by the air supply source. At this time, the lower cylinder is in an independent compression operating mode. When the control component controls both the air supply port 6 and the air inlet 5 to be open, the refrigerant gas in the chamber 2 and the refrigerant gas provided by the air supply source both flow into the lower cylinder from the exhaust pipe 4 for compression, and the lower cylinder is in an air supply enthalpy increase operating mode.

[0029] In the case where both exhaust pipes 4 are provided with air inlets 6 and control components, the upper cylinder and the lower cylinder both have several operation modes, namely, conventional operation, independent compression operation, and air inlet enthalpy increase operation. Therefore, the combination of the operation modes of the upper cylinder and the lower cylinder includes: dual conventional operation, dual independent compression operation, dual air inlet enthalpy increase operation, single conventional single independent compression operation, single conventional single air inlet enthalpy increase operation, and single air inlet enthalpy increase single independent compression operation. Among them, "dual" refers to the upper cylinder and the lower cylinder, which means that the operation modes of the upper cylinder and the lower cylinder are the same; "single" refers to the upper cylinder or the lower cylinder.

[0030] With such arrangement, the compressor has a plurality of operating modes. By controlling the opening and closing of the air inlet 5 and the opening and closing of the air supply port 6 through the control component, a plurality of operating modes of the compressor, including normal operation, air supply and enthalpy increase operation and independent compression operation, can be realized. There is no need to add additional components such as a liquid distributor to the compressor. The reliability of the compressor is higher, the assembly requirements of the compressor are reduced, and it is beneficial to improve the assembly efficiency of the compressor.

[0031] In the case where the compressor has three or more cylinders, the liquid distributor is provided with exhaust pipes equal to the number of cylinders. Each cylinder has normal operation, independent compression operation and air supply and enthalpy increase operation modes. The operation mode of the compressor includes a combination of different operation modes of each cylinder. Therefore, the more cylinders the compressor has, the more operation modes there are.

[0032] In the preferred solution of this embodiment, the control member is a moving component arranged in the exhaust pipe 4, and the moving component can move in the exhaust pipe 4, and the moving position includes a first position, a second position and a third position. When the moving component moves to the first position, it blocks the air inlet 5, and the air supply port 6 is in an open state, and the cylinder corresponding to the exhaust pipe 4 is in a single independent compression operation mode; when the moving component moves to the second position, it blocks the air supply port 6, and the air inlet 5 is in an open state, and the cylinder corresponding to the exhaust pipe 4 is in a normal operation mode; when the moving component moves to the third position, the air inlet 5 and the air supply port 6 are both in an open state, and the cylinder corresponding to the exhaust pipe 4 is in an air supply enthalpy increase operation mode.

[0033] With such arrangement, the movable component moves to different positions in the exhaust pipe 4, thereby controlling the opening and closing of the air inlet 5 and the air supply port 6, and further controlling the operation mode of the compressor. The structure of the liquid distributor is simple, and the control and use of the compressor are more convenient.

[0034] Furthermore, the moving assembly includes an elastic member 9 and a slider 8. The slider 8 is slidably disposed in the exhaust pipe 4. One end of the elastic member 9 is fixedly connected to the slider 8, and the other end is fixedly connected to the inner wall of the exhaust pipe 4. The slider 8 is subjected to the traction force exerted by the elastic member 9, its own gravity, and the driving force exerted by the refrigerant gas flowing in from the air inlet 5 and the air supply port 6. Of course, the slider 8 may also be subjected to the friction between the inner wall of the exhaust pipe 4 and the air resistance during the sliding process. The slider 8 slides along the axial direction of the exhaust pipe 4 under the combined effect of the above forces.

[0035] Specifically, the size and direction of the resultant force on the slider 8 are adjusted by controlling the size of the gas supply pressure of the gas supply port 6, so that the slider 8 slides in the exhaust pipe 4. When the slider 8 slides to the first position, the gas inlet 5 is blocked; when the slider 8 slides to the second position, the gas supply port 6 is blocked; when the slider 8 slides to the third position, the gas supply port 6 and the gas inlet 5 are not blocked by the slider 8, and the gas flowing in from the gas supply port 6 and the gas inlet 5 enters the corresponding cylinder for compression.

[0036] In the preferred solution of this embodiment, the contour of the peripheral side wall of the slider 8 is the same as the contour of the inner wall surface of the exhaust pipe 4, and the peripheral side wall of the slider 8 is in contact with the inner wall surface of the exhaust pipe 4. That is, the cross section of the slider 8 is the same in shape and area as the cross section of the internal space of the exhaust pipe 4. The slider 8 is provided with a channel 10 through which the refrigerant gas flows. In this way, the slider 8 can slide stably in the exhaust pipe 4, and the channel 10 on the slider 8 can allow the refrigerant gas flowing into the air inlet 5 or the air supply port 6 located above the slider 8 to flow downward and then flow into the cylinder.

[0037] Preferably, at least two channels 10 are provided on the slider 8. Such arrangement enables the cylinder to have sufficient air intake.

[0038] In this embodiment, at least two exhaust pipes 4 are provided, and the compressor also has at least two cylinders, and each exhaust pipe 4 is connected to each cylinder in a one-to-one correspondence. Each exhaust pipe 4 is provided with an air supply port 6, an elastic member 9 and a slider 8, and each exhaust pipe 4 is provided with at least two air inlets 5, and each air inlet 5 on the exhaust pipe 4 is located at the same height of the exhaust pipe 4. That is, the distance between each air inlet 5 of the exhaust pipe 4 and the upper end of the exhaust pipe 4 is equal. In this arrangement, when the slider 8 slides to the first position, the outer peripheral wall of the slider 8 can block each air inlet 5 on the corresponding exhaust pipe 4. The elastic member 9 can be, but is not limited to, a spring.

[0039] In the preferred solution of this embodiment, the exhaust pipe 4 includes an outer pipe section 41 arranged outside the cylinder 1 and an inner pipe section 42 extending into the chamber 2, and the outer pipe section 41 of the exhaust pipe 4 is connected to the cylinder of the compressor. Each air inlet 5 and air supply port 6 of the exhaust pipe 4 are arranged on the peripheral side wall of the inner pipe section 42. In order to ensure that the air inlet 5 has sufficient air intake, the air inlet 5 is arranged above the air supply port 6. In this way, the air inlet 5 and the air supply port 6 are located on the peripheral side wall of the exhaust pipe 4. During the sliding process of the slider 8 along the axial direction of the exhaust pipe 4, it is convenient for the slider 8 to control the opening and closing state of the air inlet 5 and the air supply port 6; moreover, the impurities and liquid components in the refrigerant gas flowing into the intake pipe 3 will not directly enter the exhaust pipe 4, thereby avoiding the cylinder of the compressor from being damaged due to liquid hammer and other problems.

[0040] In the present embodiment, the exhaust pipe 4 is provided with an air supply pipeline 7 connected to the air supply port 6, and the air supply pipeline 7 passes through the cylinder 1 and is connected to the air supply source. It should be noted that the air supply source can be a flash evaporator of the air conditioner, and a valve body is arranged between the flash evaporator and the air supply port 6. The air supply pressure in the air supply pipeline 7 is adjusted by the valve body, and then the position of the slider 8 in the exhaust pipe 4 is adjusted to realize the slider 8 to control the opening and closing state of the air inlet 5 and the air supply port 6. Among them, the valve body can be but is not limited to an electronic expansion valve. Of course, in other embodiments, the air supply source can also be an external air source, and the air supply pressure of the air supply source can be artificially controlled. By adjusting the air supply pressure of the air supply source, the slider 8 can slide in the exhaust pipe 4.

[0041] The following content specifically describes the present liquid distributor in combination with the above-mentioned embodiments. In this embodiment, the liquid distributor includes a cylinder 1, an air inlet pipe 3 and two exhaust pipes 4 arranged on the cylinder 1. Each exhaust pipe 4 is connected to the upper cylinder and the lower cylinder of the compressor one by one. Each exhaust pipe 4 is provided with an air supply port 6 and at least two air inlets 5 on the peripheral side wall. Each air inlet 5 of the exhaust pipe 4 is located at the same height of the exhaust pipe 4, and the air inlet 5 of each exhaust pipe 4 is arranged above the air supply port 6. The air supply port 6 is connected to the air supply source through the air supply pipeline 7. Each exhaust pipe 4 is provided with a slider 8 and an elastic member 9. One end of the elastic member 9 is connected to the top inner wall surface of the exhaust pipe 4, and the other end is connected to the upper end surface of the slider 8. The cross section of the slider 8 is the same as the cross section of the internal space of the exhaust pipe 4. The slider 8 is provided with at least two channels 10 that penetrate the upper and lower end surfaces of the slider 8 for the refrigerant gas to flow through.

[0042] The slider 8 is subjected to the traction of the elastic member 9, its own gravity, the thrust of the refrigerant gas flowing into the exhaust pipe 4 from the air inlet 5 and the air replenishment port 6, etc., and the slider 8 slides along the axial direction of the exhaust pipe 4 under the action of the combined force. When the slider 8 is not subjected to the thrust of the refrigerant gas flowing into the exhaust pipe 4 from the air inlet 5 and the air replenishment port 6, the slider 8 stops at a certain position between the air replenishment port 6 and the air inlet 5 under the action of the force applied by the elastic member 9 and gravity. When the gas pressure flowing into the air inlet 5 of the exhaust pipe 4 is relatively high, the slider 8 is pushed to move downward to block the air supply port 6, and the slider 8 moves to the second position. At this time, the cylinder connected to the exhaust pipe 4 is in a normal operation state; if the gas pressure flowing into the air supply port 6 of the exhaust pipe 4 is relatively high, the slider 8 is pushed to move upward to block the air inlet 5, and the slider 8 moves to the first position. At this time, the cylinder connected to the exhaust pipe 4 is in an independent compression operation state; if the slider 8 is still located between the air inlet 5 and the air supply port 6 under the joint driving action of the gas pressure of the air inlet 5 and the air supply port 6, that is, the slider 8 is in the third position, at this time, the cylinder connected to the exhaust pipe 4 is in a gas supply and enthalpy increase operation state.

[0043] With such arrangement, the force applied to the slider 8 is changed by controlling the air supply pressure of the air supply port 6, so that the slider 8 moves in the exhaust pipe 4 to control the opening and closing of the air inlet 5 and the air supply port 6, thereby realizing multiple modes of operation of the compressor without adding additional components such as a liquid distributor, thereby improving the reliability of the compressor, reducing the assembly requirements of the compressor, and being conducive to improving the assembly efficiency of the compressor.

[0044] The present invention also provides a compressor, including a liquid separator and a cylinder, and the liquid separator is the liquid separator in the above embodiment. The liquid separator is provided with exhaust pipes having the same number as the cylinders of the compressor, and each exhaust pipe is connected to the cylinder in a one-to-one correspondence. With such a configuration, the multi-mode operation of the compressor can be controlled by the liquid separator, and the opening and closing states of the air inlet 5 and the air inlet 6 of the exhaust pipe can be controlled by adjusting the air intake pressure of the air inlet 6, so as to control the operation state of the corresponding cylinder, so that the cylinder can perform conventional operation, air inlet enthalpy increase operation and independent operation, and the compressor does not need to be additionally controlled with components, thereby improving the reliability of the compressor, making the structure of the compressor simpler, and being conducive to improving the assembly efficiency of the compressor. The derivation process of this beneficial effect is generally similar to the derivation process of the beneficial effect brought about by the liquid separator, so it will not be repeated in this article.

[0045] The present invention further provides an air conditioner, including a compressor, which is the compressor in the above embodiment. With such a configuration, the compressor has multiple operating modes such as conventional operation, air-inflation enthalpy-increasing operation, and independent compression operation, and can be achieved by controlling the air intake pressure of the air-inflation port 6, without the need to add additional components such as a liquid distributor, thereby improving the reliability of the compressor, reducing the assembly requirements of the compressor, and helping to improve the assembly efficiency of the compressor. At the same time, the compressor has multiple operating modes, which can be applied to various working conditions of the air conditioner, and is helpful to reduce the energy consumption of the air conditioner. The derivation process of this beneficial effect is generally similar to the derivation process of the beneficial effect brought about by the compressor, so it will not be repeated herein.

[0046] In the preferred solution of this embodiment, the air conditioner includes a flash evaporator, and the air supply port 6 is connected to the flash evaporator through an air supply pipe 7, and a valve body is provided on the air supply pipe 7. The valve body can be, but is not limited to, an electronic expansion valve. Preferably, the control member includes a slider 8 and an elastic member 9 arranged in the exhaust pipe 4, and the air supply pressure of the air supply port 6 is adjusted by the valve body, thereby adjusting the position of the slider 8 in the exhaust pipe 4, so that the slider 8 controls the opening and closing state of the air inlet 5 and the air supply port 6.

[0047] With such arrangement, the air supply port 6 is supplied with air by the flash evaporator, the structure of the air conditioner is simple, and the various operation modes of the compressor can be realized by controlling the air supply pressure of the air supply port 6, without adding components such as a liquid distributor, thereby improving the reliability and assembly efficiency of the compressor.
