[0032] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] A heat pump system 1000 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0034] like Figure 1 , Figure 2 As shown, the heat pump system 1000 according to an embodiment of the present invention includes an evaporator 10, a condenser 20 and a compressor 30.

[0035] The compressor 30 has a compression chamber 31 and a throttling chamber 32. The outlet 312 of the compression chamber 31 is connected to the refrigerant inlet of the condenser 20. The refrigerant outlet of the condenser 20 is connected to the liquid inlet 321 of the throttling chamber 32. The liquid outlet 322 of the throttling chamber 32 is connected to the refrigerant inlet of the evaporator 10. The refrigerant outlet of the evaporator 10 is connected to the air inlet 311 of the compression chamber 31.

[0036] The compressor 30 includes a compression component 33, which is operably disposed in the compression chamber 31. When the compression component 33 operates in the compression chamber 31, it can compress the gaseous refrigerant in the compression chamber 31 to form a high-temperature and high-pressure gaseous refrigerant.

[0037] Specifically, the high-temperature and high-pressure gaseous refrigerant in the compression chamber 31 flows to the condenser 20 through the outlet 312. After releasing heat in the condenser 20, it becomes a high-pressure liquid refrigerant. The high-pressure liquid refrigerant enters the throttling chamber 32 through the inlet 321. The liquid refrigerant in the throttling chamber 32 flows to the evaporator 10 through the outlet 322. The liquid refrigerant flowing through the throttling chamber 32 is throttled and depressurized, becoming a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is suitable for absorbing heat at the evaporator 10, becoming a low-pressure gaseous refrigerant. The low-temperature gaseous refrigerant enters the compression chamber 31 through the inlet 311.

[0038] In summary, the refrigerant can circulate between the compression chamber 31, the condenser 20, the throttling chamber 32, and the evaporator 10. When the refrigerant flows through the condenser 20, it releases heat at the condenser 20, which can then be used for heating, drying clothes, etc., thus acting as a heat pump.

[0039] The compressor 30 also includes a rotating component 34, which is rotatably disposed in the throttling chamber 32. Specifically, when the refrigerant in the throttling chamber 32 flows through the rotating component 34, it can perform work on the rotating component 34 to recover the energy in the refrigerant.

[0040] The compression component 33 and the rotating component 34 are connected by a transmission. When the refrigerant in the throttling chamber 32 does work on the rotating component 34, the rotating component 34 can transfer energy to the compression component 33 to provide energy for the operation of the compression component 33.

[0041] Specifically, when the refrigerant flows through the throttling chamber 32, the throttling chamber 32 reduces the pressure of the refrigerant, thus acting as a throttling device. The refrigerant entering the throttling chamber 32 from the liquid inlet 321 is high-pressure refrigerant, and the refrigerant flowing out of the throttling chamber 32 is low-pressure refrigerant. In other words, the energy of the refrigerant decreases after flowing through the throttling chamber 32.

[0042] By setting a rotating component 31 in the throttling cavity 32, the liquid refrigerant comes into contact with the rotating component 34 after flowing through the throttling cavity 32. The refrigerant does work on the rotating component 34 to convert part of the energy lost by the refrigerant into the energy of the rotating component 34, and the rotating component 34 is used to recover the energy lost by the refrigerant in the throttling cavity 32.

[0043] The energy recovered by the rotating component 34 can be applied to the compression component 33 to provide energy for the operation of the compression component 33, which facilitates the full utilization of energy, improves the energy utilization rate, and achieves a significant energy-saving effect.

[0044] According to the heat pump system 1000 of the present invention, the compressor 30 has the ability to throttle and reduce the pressure of the refrigerant. The rotating component 34 can recover the energy lost by the refrigerant in the throttling chamber 32 and provide energy for the operation of the compression component 33. This facilitates the full utilization of energy, improves the energy utilization rate, and achieves a significant energy-saving effect.

[0045] A heat pump system 1000 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0046] In some specific embodiments of the present invention, such as Figure 1 , Figure 2 As shown, the heat pump system 1000 includes an evaporator 10, a condenser 20, and a compressor 30.

[0047] In some embodiments of the present invention, the compressor 30 further includes a transmission member 40, which cooperates with the rotating component 34 and the compression component 33 respectively, so that when the refrigerant in the throttling chamber 32 does work on the rotating component 34, the rotating component 34 can transfer energy to the compression component 33 through the transmission member 40 to provide energy for the operation of the compression component 33.

[0048] Specifically, the energy recovered by the rotating component 34 is transmitted to the compression component through the transmission component 40 to provide energy for the operation of the compression component 33, thereby making full use of energy, improving the energy utilization rate, and achieving a significant energy-saving effect.

[0049] In some embodiments of the present invention, such as Figure 2 As shown, the compressor 30 also includes a motor 38, which drives the compression component 33 to operate in the compression chamber 31 so that the compression component 33 can compress the refrigerant in the compression chamber 31.

[0050] The transmission component 40 includes a first transmission shaft 41, through which the motor 38 is connected to the rotating component 34 to realize the connection between the rotating component 34 and the motor 38.

[0051] Specifically, when the refrigerant in the throttling chamber 32 flows through the rotating component 34 and does work on the rotating component 34, the rotating component 34 transmits the recovered energy to the motor 37 through the first transmission rod shaft 41, and together with the motor 37, provides energy for the operation of the compression component 33, which helps to reduce the energy consumed by the motor 37.

[0052] In some embodiments, the motor 38 is used to drive the compression component 33 to rotate, and the motor 38 can also drive the rotating component 34 to rotate via the first transmission shaft 41.

[0053] When the refrigerant flows through the rotating component 34, the refrigerant does work on the rotating component 34, and the torque generated by the rotating component 34 acts on the first drive shaft 41, which is suitable to act on the compression component 33 together with the torque generated by the motor 38. This makes it easier to reduce the torque that the motor 38 itself needs to provide for the operation of the compression component 33, and to save energy.

[0054] Specifically, when the motor 38 independently drives the compression component 33, the motor 38 needs to provide a large torque for the operation of the compression component 33, which in turn requires a lot of energy. The present invention utilizes the rotating component 34 to recover the energy of the refrigerant in the throttling chamber 32. The torque generated by the rotating component 34 acts on the first transmission shaft 41, which is suitable to act on the compression component 33 together with the torque generated by the motor 38. This reduces the torque that the motor 38 needs to provide for the operation of the compression component 33, thereby reducing the energy consumed and achieving a good energy-saving effect.

[0055] In some alternative embodiments of the present invention, such as Figure 2 As shown, the transmission component 40 also includes a second transmission shaft 42, through which the motor 38 is connected to the compression component 33, so as to drive the compression component 33 to operate via the second transmission shaft 42.

[0056] In some embodiments, the compression component 33 is rotatably disposed in the compression chamber 31, and the motor 38 drives the compression component 33 to rotate through the second transmission shaft 42 so that the compression component 33 can compress the gas in the compression chamber 31.

[0057] In some examples, the motor shaft of the motor 38 defines a first drive shaft 41 and a second drive shaft 42, which are connected to the rotating component 34 and the compression component 33, respectively. When the motor 38 is working, it drives the compression component 33 to rotate in the compression chamber 31 through the second drive shaft 42. The energy recovered by the rotating component 34 is suitable for being transmitted to the motor 37 through the first drive shaft 41, together with the motor 37, to provide energy for the operation of the compression component 33.

[0058] In some examples, the motor shaft of the motor 38 defines a second drive shaft 42, and the first drive shaft 41 is connected to the second drive shaft 42. When the motor 38 is working, the motor 38 drives the compression component 33 to rotate in the compression chamber 31 through the second drive shaft 42. The energy recovered by the rotating component 34 is suitable for being transmitted to the motor 37 through the first drive shaft 41, together with the motor 37, to provide energy for the operation of the compression component 33.

[0059] In some alternative embodiments of the present invention, such as Figure 2 As shown, the rotating component 34 and the compression component 33 are located at both ends of the motor 38 in the axial direction. This makes it easier to control the length of the rotating component extending out of the motor 38 and avoids the rotating component having too low stiffness due to excessive length of the rotating component extending out of the motor 38.

[0060] Specifically, if the length of the first drive shaft 41 extending out of the motor 38 is too long, the end of the first drive shaft 41 away from the motor 38 is prone to bending, which in turn can easily affect the cooperation between the first drive shaft 41 and the rotating component 34 and the compression component 33.

[0061] Furthermore, positioning the rotating component 34 and the compression component 33 at opposite ends of the motor 38 along the axial direction facilitates controlling the center of gravity of the compressor 30 on the motor 38 in the middle of the compressor 30. This enhances the stability of the compressor 30 and facilitates its stable operation. Specifically, during operation, this reduces the likelihood or amplitude of swaying of the rotating component 34 and the compression component 33.

[0062] In some embodiments, such as Figure 2 As shown, the transmission component 40 includes a first transmission shaft 41 and a second transmission shaft 42. The first transmission shaft 41 extends axially out of the motor housing of the motor 38 to connect with the rotating component 34, and the second transmission shaft 42 extends axially out of the motor housing of the motor 38 to connect with the compression component 33.

[0063] The rotating component 34 and the compression component 33 are located at the two ends of the motor 38 in the axial direction, which makes it easier to reduce the distance between the rotating component 34 and one end of the motor housing in the axial direction, thereby making it easier to reduce the length of the first drive shaft 41 extending out of the motor housing, and avoiding the first drive shaft 41 from bending easily due to the excessive length of the first drive shaft 41 extending out of the motor housing.

[0064] The rotating component 34 and the compression component 33 are located at the two ends of the motor 38 in the axial direction, which makes it easier to reduce the distance between the compression component 33 and the other end of the motor housing in the axial direction. This makes it easier to reduce the length of the second drive shaft 42 extending out of the motor housing, and avoids the second drive shaft 42 from bending easily due to excessive length extending out of the motor housing.

[0065] In some alternative embodiments of the present invention, such as Figure 2As shown, the compressor 30 also includes a housing 35 and a partition 36. The partition 36 is disposed inside the housing 35 and divides the housing 35 into a first chamber and a second chamber 37. The rotating component 34 is disposed in the first chamber, and the motor 38 and the compression component 33 are disposed in the second chamber 37, so as to separate the compression component 33 and the rotating component 34 of the compressor 30, and to separate the compression chamber 31 and the throttling chamber 32 of the compressor 30, so as to avoid the mutual influence of refrigerants of different forms.

[0066] In addition, this makes it easier to keep the walls of the first and second chambers 37 under low pressure, thereby reducing the force on the housing 35 and improving the service life of the compressor 30.

[0067] In some alternative embodiments of the present invention, such as Figure 2 As shown, the first chamber is a throttling chamber 32. The inlet 321 and the outlet 322 are located on the walls of the first chamber opposite to each other. When the liquid refrigerant enters the first chamber from the inlet 321 and flows out of the first chamber from the outlet 322, the liquid refrigerant has an impact force on the rotating component 34 in the throttling chamber 32, thereby realizing the work done on the rotating component 34. The rotating component 34 can recover the energy lost by the refrigerant in the throttling chamber 32, providing energy for the operation of the compression component 33. This facilitates the full utilization of energy, improves the energy utilization rate, and achieves a significant energy-saving effect.

[0068] The liquid inlet 321 and liquid outlet 322 are located on the walls of the first chamber opposite each other, which facilitates the increase of the impact force of the liquid refrigerant on the rotating component 34, thereby improving the efficiency of the rotating component 34 in recovering energy from the refrigerant.

[0069] In some optional embodiments of the present invention, the partition 36 is provided with a through-hole, through which the first drive shaft 41 passes, so that one end of the first drive shaft 41 is connected to the motor in the second chamber 37, and the other end can extend into the first chamber and connect to the rotating component 34. Specifically, one end of the first drive shaft 41 is connected to or cooperates with the motor shaft of the motor 38, and the other end passes through the through-hole and connects to the rotating component 34 in the first chamber, so that the energy recovered by the rotating component 34 can be transmitted to the motor 37 through the first drive shaft 41, and together with the motor 37, provide energy for the operation of the compression component 33, which helps to reduce the energy consumed by the motor 37.

[0070] In some alternative embodiments of the present invention, the first drive shaft 41 is sealed with a port to prevent the liquid refrigerant in the first chamber from leaking into the second chamber 37.

[0071] Specifically, the liquid refrigerant is suitable for flowing through the first chamber, so that the first drive shaft 41 is sealed with the port, so as to prevent the refrigerant in the first chamber from leaking into the second chamber 37 through the gap between the first drive shaft 41 and the port.

[0072] In some alternative embodiments of the invention, the rotating component 34 includes a turbine.

[0073] In some embodiments, the rotating component 34 includes an axial turbine. The throttling chamber 32 has an inlet 321 and an outlet 322 on the two side walls of the axial turbine. When liquid enters the throttling chamber 32 from the inlet 321 at one end of the axial direction of the axial turbine and flows out from the outlet 322 at the other end of the axial direction of the axial turbine, the liquid refrigerant exerts a force on the axial turbine to drive its rotation, thereby doing work on the axial turbine. The axial turbine recovers the energy lost by the refrigerant in the throttling chamber 32 to provide energy for the operation of the compression component 33, which facilitates the full utilization of energy, improves the energy utilization rate, and achieves a significant energy-saving effect.

[0074] In other embodiments, the rotating component 34 includes a radial turbine. The throttling chamber 32 has an inlet 321 and an outlet 322 on the two radially upward side walls of the radial turbine. When liquid enters the throttling chamber 32 from the inlet 321 at one radial end of the radial turbine and flows out from the outlet 322 at the other radial end of the radial turbine, the liquid refrigerant exerts a force on the radial turbine to drive its rotation, thereby doing work on the radial turbine. The energy lost by the refrigerant in the throttling chamber 32 is recovered by the radial turbine to provide energy for the operation of the compression component 33, which facilitates the full utilization of energy, improves the energy utilization rate, and achieves a significant energy-saving effect.

[0075] Of course, the turbine can also be a mixed-flow turbine or other types of turbines; we will not impose too many restrictions here.

[0076] In some optional embodiments of the present invention, the flow area of ​​the liquid outlet 322 is smaller than that of the liquid inlet 321, so that after the refrigerant flows through the throttling cavity 32 and then flows through the liquid inlet 321 and the liquid outlet 322 in sequence, it can play the role of throttling and reducing the pressure of the refrigerant, thereby converting the high-pressure liquid refrigerant into a low-temperature and low-pressure liquid refrigerant.

[0077] Specifically, when the liquid flows through the outlet 322 with a small flow area, the liquid flows at a high speed in the narrow outlet 322, causing the static pressure at that point to drop significantly, thereby reducing the pressure of the liquid refrigerant.

[0078] In some embodiments of the present invention, the operation of the compression component 33 in the compression chamber 31 can be reciprocating movement or rotation, depending on the specific structure of the compressor 30.

[0079] In some embodiments, the compressor 30 includes a cylinder that defines a compression chamber 31, the compression component 33 is a piston, and the motor shaft of the motor 38 is connected to the piston via a crankshaft to drive the piston to reciprocate within the compression chamber 31, thereby enabling the piston to compress the gaseous refrigerant within the compression chamber 31 to form a high-temperature and high-pressure gaseous refrigerant.

[0080] In other embodiments, the compressor 30 includes a cylinder, the compression component 33 is an eccentric rotor, and the motor shaft of the motor 38 cooperates with the eccentric rotor to drive the eccentric rotor to rotate, thereby enabling the eccentric rotor to compress the gaseous refrigerant in the compression chamber 31 to form a high-temperature and high-pressure gaseous refrigerant.

[0081] In some embodiments, the compressor 30 includes a stationary scroll, the compression component 33 is a moving scroll, and a compression chamber 31 is defined between the stationary scroll and the moving scroll. The motor shaft of the motor 38 cooperates with the moving scroll to drive the moving scroll to rotate, thereby enabling the moving scroll to compress the gaseous refrigerant in the compression chamber 31 to form a high-temperature and high-pressure gaseous refrigerant.

[0082] In some embodiments, the compression component 33 includes a first screw and a second screw that mesh with each other. The first screw and the second screw are engaged, and the motor 38 is engaged with the first screw. When the motor 38 drives the first screw to rotate, the first screw drives the second screw to rotate. Gas is suitable to enter the chamber formed by the first screw and the second screw through the air inlet 311. When the first screw and the second screw rotate, the gas in the chamber moves towards the air outlet 312. At the same time, the volume of the chamber formed by the first screw and the second screw gradually decreases, and the gas is compressed to form a high-temperature and high-pressure gaseous refrigerant.

[0083] The following describes a clothes dryer 500 according to an embodiment of the present invention. The clothes dryer 500 according to an embodiment of the present invention includes a heat pump system 1000 according to the above embodiment of the present invention.

[0084] Specifically, the heat pump system 1000 can provide heat, and the dryer 500 can use the heat provided by the heat pump system 1000 to dry clothes.

[0085] Specifically, the compression component 33 can compress the gaseous refrigerant in the compression chamber 31 to form a high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant flows to the condenser 20 through the outlet 312. After releasing heat in the condenser 20, it becomes a high-pressure liquid refrigerant. The high-pressure liquid refrigerant enters the throttling chamber 32 through the inlet 321. The liquid refrigerant in the throttling chamber 32 flows to the evaporator 10 through the outlet 322. The liquid refrigerant flowing through the throttling chamber 32 is throttled and depressurized, becoming a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is suitable for absorbing heat at the evaporator 10 and becoming a low-pressure gaseous refrigerant. The low-temperature gaseous refrigerant enters the compression chamber 31 through the inlet 311.

[0086] When the refrigerant flows through the condenser 20, the refrigerant releases heat at the condenser 20, and the dryer 500 can use the heat released by the refrigerant at the condenser 20 to dry the clothes.

[0087] The dryer 500 according to an embodiment of the present invention utilizes the heat pump system 1000 according to the above embodiment of the present invention. The compressor 30 has the ability to throttle and reduce the pressure of the refrigerant. The rotating component 34 can recover the energy lost by the refrigerant in the throttling chamber 32 and provide energy for the operation of the compression component 33. This facilitates the full utilization of energy, improves the energy utilization rate, and achieves a significant energy-saving effect.

[0088] In some embodiments of the present invention, such as Figure 3 , Figure 4 As shown, the dryer 500 also includes a drum 51 and an air circulation system. The air circulation system includes an air duct and a blower 55. The air outlet of the drum 51 is connected to the inlet of the air duct, and the air outlet of the air duct is connected to the air inlet of the drum 51. The blower 55 is used to drive air to circulate within the drum 51 and between the air duct, thereby using air to dry the clothes inside the drum 51.

[0089] The evaporator 10 and condenser 20 are located in the air duct. The air flowing out of the drum 51 becomes humid hot air after contacting the clothes. The humid hot air flows from the air outlet of the drum 51 into the air duct. When the air flows in the air duct and passes through the evaporator 10, the low-temperature refrigerant in the evaporator 10 is suitable for absorbing the heat in the air, so that the humid hot air is liquefied into condensate, and thus the air flowing through the evaporator 10 becomes dry cold air. When the dry cold air flows in the air duct and passes through the condenser 20, the high-temperature and high-pressure refrigerant in the condenser 20 is suitable for releasing heat, so that the air flowing through the condenser 20 becomes dry hot air. The dry hot air is suitable for entering the drum 51 along the air duct to dry the clothes. The air becomes humid hot air after passing through the clothes in the drum 51.

[0090] In summary, by circulating air between the air duct and the drum, the evaporator 10 and the condenser 20 can turn the humid air into dry hot air, thereby drying the clothes in the drum 51.

[0091] In some embodiments, such as Figure 3 As shown, the air duct includes a front air duct 53 and a rear air duct 54 that are connected. The front air duct 53 is located on the front side of the drum 51, and the rear air duct 54 is located on the rear side of the drum 51. (It should be understood that the above directional limitation is only for the convenience of describing the attached drawings and does not limit the actual installation position and direction of the heat pump system 1000).

[0092] The front air duct 53 and the rear air duct 54 are designed to optimize the hot air circulation efficiency, improve the drying effect, and ensure the safe operation of the machine.

[0093] Specifically, one of the front air duct 53 and the rear air duct 54 is adapted to draw in outside air to ensure that enough fresh air enters and maintains the drying temperature. The other of the front air duct 53 and the rear air duct 54 is adapted to guide the heated and dried hot air into the drum, so that the dried hot air comes into contact with the clothes and absorbs moisture, and then the moisture is discharged through the dehumidification system to avoid moisture backflow and secondary dampness of the clothes.

[0094] In addition, designing the air duct into a split-channel configuration helps reduce condensation trapped in the air duct, preventing condensation from remaining inside the machine and reducing the risk of mold growth or circuit damage.

[0095] In some embodiments, the drum 51 has a loading port, which a user is adapted to place clothes into the drum 51 from the loading port. The dryer 500 also includes a door 52 for opening or closing the loading port of the drum 51.

[0096] In some embodiments, the dryer 500 further includes a drive unit 56, which is adapted to drive the drum 51 to rotate, thereby turning the clothes inside the drum 51 so that the hot air can fully contact the clothes and improve the drying effect.

[0097] In some examples, the drive unit 56 drives the roller 51 to rotate via a belt.

[0098] Other configurations and operations of the dryer 500 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
