[0033] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0034] Reference below Figures 1-9 A dehumidifier 1 according to an embodiment of the present invention will be described.

[0035] like Figure 1 and Figure 2 As shown, a dehumidifier 1 according to an embodiment of the present invention includes: a housing 10, a compressor 20, a first heat exchanger 30, a first fan 40, a second heat exchanger 50, a throttling element 60, and a second fan 70. The housing 10 primarily constitutes the structure of the dehumidifier 1, giving it a more integrated and concise appearance. The housing 10 also provides protection, preventing the components inside the housing 10 from coming into contact with foreign objects and being damaged. The compressor 20 compresses the refrigerant, forming a high-pressure gas. Both the first heat exchanger 30 and the second heat exchanger 50 function as heat exchangers. Through their cooperation, both cooling and heating effects can be achieved. The first fan 40 and the second fan 70 can rotate to generate suction, drawing external air into the dehumidifier 1. The throttling element 60 acts as a throttling and pressure reduction device.

[0036] It should be noted that the shell 10 is provided with a wall mounting portion, so that the shell 10 can be set in the wall through the wall mounting portion, so that the dehumidifier 1 can be embedded in the wall as a whole, preventing the problem of radiant cooling dew point control, preventing condensation during radiant cooling, and avoiding the dehumidifier 1 occupying indoor space. In addition, the compressor 20 can be arranged on the outdoor side to solve the problem of high noise of the traditional dehumidifier 1.

[0037] like Figure 1 、 Figure 3 and Figure 4 As shown, an air supply channel 11 and an air exhaust channel 12 are formed in the housing 10. The air supply channel 11 and the air exhaust channel 12 can be arranged vertically or horizontally. The outer and inner sides of the air supply channel 11 correspond to a first outdoor air outlet 110 and a first indoor air outlet 111, respectively. The outer and inner sides of the air exhaust channel 12 correspond to a second outdoor air outlet 120 and a second indoor air outlet 121, respectively. The air supply channel 11 and the exhaust channel 12 are both air circulation channels. The air supply channel 11 mainly serves as an air supply channel. The first outdoor air outlet 110 and the first indoor air outlet 111 are respectively provided on the outer and inner sides of the air supply channel 11. The air generally flows from the first outdoor air outlet 110 to the first indoor air outlet 111 in the air supply channel 11. The exhaust channel 12 mainly serves as an air exhaust channel. The second outdoor air outlet 120 and the second indoor air outlet 121 are respectively provided on the outer and inner sides of the exhaust channel 12. The air generally flows from the second indoor air outlet 121 to the second outdoor air outlet 120 in the exhaust channel 12.

[0038] like Figure 2 and Figure 3As shown, a first heat exchanger 30 is disposed within the air supply duct 11 and is connected to one end of the compressor 20. A first fan 40 is also disposed within the air supply duct 11 and is spaced apart from the first heat exchanger 30. The first heat exchanger 30 is disposed within the air supply duct 11 so that it can exchange heat with the air within the duct 11. The first heat exchanger 30 is connected to one end of the compressor 20 so that the refrigerant compressed by the compressor 20 can flow into the first heat exchanger 30, thereby fulfilling the heat exchange function of the first heat exchanger 30. The first fan 40 is disposed within the air supply duct 11 so that it can draw air into the duct 11. The first fan 40 is spaced apart from the first heat exchanger 30 to avoid interference between the first fan 40 and the first heat exchanger 30 and to facilitate air flow through the first heat exchanger 30.

[0039] like Figure 2 and Figure 3 As shown, a second heat exchanger 50 is disposed within the exhaust duct 12 and is connected to the other end of the compressor 20. A second fan 70 is also disposed within the exhaust duct 12, spaced apart from the second fan 70. The second heat exchanger 50 is disposed within the exhaust duct 12 so that it can exchange heat with the air within the exhaust duct 12. The second heat exchanger 50 is connected to the other end of the compressor 20 so that the refrigerant compressed by the compressor 20 can flow into the second heat exchanger 50, thereby fulfilling the heat exchange function of the second heat exchanger 50. The second fan 70 is disposed within the exhaust duct 12 so that it can draw air into the exhaust duct 12. The second fan 70 is spaced apart from the second heat exchanger 50 to avoid interference between the second fan 70 and the second heat exchanger 50 and to facilitate air flow through the second heat exchanger 50.

[0040] like Figure 2 As shown, when one of the second heat exchanger 50 and the first heat exchanger 30 functions as a condenser, the other of the second heat exchanger 50 and the first heat exchanger 30 functions as an evaporator, and a throttling element 60 is connected between the second heat exchanger 50 and the first heat exchanger 30. In other words, when one of the second heat exchanger 50 and the first heat exchanger 30 releases heat, the other absorbs heat. Thus, when the first heat exchanger 30 and the second heat exchanger 50 work together, a cooling or heating cycle can be achieved, thereby enabling the dehumidifier 1 to operate normally. The throttling element 60 is connected between the second heat exchanger 50 and the first heat exchanger 30. This throttling element can throttle the refrigerant between the first heat exchanger 30 and the second heat exchanger 50, thereby improving the heat exchange between the first heat exchanger 30 and the second heat exchanger 50.

[0041] Specifically, during fresh air dehumidification in summer, the gas refrigerant discharged from the compressor 20 enters the second heat exchanger 50, which is a condenser at this time, and then passes through the throttling device to enter the first heat exchanger 30, which is an evaporator at this time. The first fan 40 is running, and the high-temperature fresh air outdoors enters the supply air duct, is cooled and dehumidified by the evaporator, and is released into the room. The low-temperature air in the room is pushed into the exhaust duct by the second fan 70, and is discharged to the outside after the cold energy is recovered by the condenser, thereby realizing the air circulation of fresh air cooling and dehumidification.

[0042] When dehumidifying the room in summer, the first outdoor air outlet 110 and the second outdoor air outlet 120 are closed, and the refrigerant is discharged from the compressor 20 and enters the first heat exchanger 30, which is now a condenser, and then passes through the throttling device to enter the second heat exchanger 50, which is now an evaporator. The indoor air is pushed into the exhaust duct by the second fan 70, and the evaporator dehumidifies the indoor air. The air is then blown into the supply air duct through a closed loop, and the cold air is heated by the condenser and then blown into the room, thereby achieving dehumidification without cooling.

[0043] When humidifying the indoor space in summer, the first indoor air outlet 111 and the second indoor air outlet 121 are closed, the first outdoor air outlet 110 and the second outdoor air outlet 120 are opened, and the compressor 20 runs at an appropriate frequency to frost the first heat exchanger 30. At this time, the first heat exchanger 30 is an evaporator. When the frost reaches a certain thickness, the first outdoor air outlet 110 and the second outdoor air outlet 120 are closed, the first indoor air outlet 111 and the second indoor air outlet 121 are opened, the compressor 20 is turned off, and the first fan 40 is run to release the water vapor on the evaporator into the room, thereby achieving a humidification effect on the room.

[0044] When the indoor and outdoor temperature and humidity are not much different, outdoor fresh air can be injected. At this time, the first heat exchanger 30 and the second heat exchanger 50 are not working, only the first fan 40 is turned on, and the second fan 70 is reversed to increase the fresh air intake.

[0045] During the winter heating season, fresh air heating can be performed. The refrigerant is discharged from the compressor 20 and enters the first heat exchanger 30. At this time, the first heat exchanger 30 is a condenser, and then passes through the throttling device to enter the second heat exchanger 50. At this time, the second heat exchanger 50 is an evaporator. The external cold air is pushed by the first fan 40 to flow through the condenser. The condenser heats it and releases it into the room. The warm air in the room is pushed by the second fan 70 to flow through the evaporator. The evaporator recovers the heat and discharges it outdoors.

[0046] When fresh air dehumidification is performed in winter, the gas refrigerant discharged from the compressor 20 enters the second heat exchanger 50, at which time the second heat exchanger 50 is a condenser, and then passes through the throttling device to enter the first heat exchanger 30, at which time the first heat exchanger 30 is an evaporator, and the first fan 40 is running. The fresh air with higher humidity outdoors enters the supply air duct, and is released into the room after being dehumidified by the evaporator. The warm air in the room is pushed into the exhaust duct by the second fan 70, and is discharged to the outside through the condenser, realizing the air circulation of fresh air dehumidification.

[0047] When humidifying the indoor space in winter, the first indoor air outlet 111 and the second indoor air outlet 121 are closed, the first outdoor air outlet 110 and the second outdoor air outlet 120 are opened, and the compressor 20 runs at an appropriate frequency to frost the first heat exchanger 30. At this time, the first heat exchanger 30 is an evaporator. When the frost reaches a certain thickness, the first outdoor air outlet 110 and the second outdoor air outlet 120 are closed, the first indoor air outlet 111 and the second indoor air outlet 121 are opened, the compressor 20 is turned off, and the first fan 40 is run to release the water vapor on the evaporator into the room, thereby achieving a humidification effect on the room.

[0048] When dehumidifying the room in winter, the first outdoor air outlet 110 and the second outdoor air outlet 120 are closed, and the refrigerant is discharged from the compressor 20 into the first heat exchanger 30, which is now a condenser, and then passes through the throttling device to enter the second heat exchanger 50, which is now an evaporator. The indoor air is pushed into the exhaust duct by the second fan 70, and the evaporator dehumidifies the indoor air. The air is then blown into the supply air duct through a closed loop, and the cold air is heated by the condenser and then blown into the room, thereby achieving dehumidification without cooling.

[0049] Therefore, the dehumidifier 1 is embedded in the wall as a whole, which prevents the problem of dew point control of radiation cooling, prevents condensation during radiation cooling, and avoids the dehumidifier 1 occupying indoor space. In addition, the compressor 20 can be arranged on the outdoor side to solve the problem of high noise of the traditional dehumidifier 1. In addition, by separately setting the supply air duct and the exhaust air duct, multiple modes of the dehumidifier 1 can be realized, the function of the dehumidifier 1 can be improved, and the heat and cold can be recovered to improve the energy-saving effect of the dehumidifier 1.

[0050] Among them, such as Figure 1 and Figure 3As shown, the housing 10 includes a main housing 13 and an inner partition 14. The main housing 13 is provided with a wall-mounting portion. The inner partition 14 is disposed within the main housing 13. An air supply channel 11 and an air exhaust channel 12 are formed on both sides of the inner partition 14. The inner partition 14 is disposed between the first heat exchanger 30 and the second heat exchanger 50. The main housing 13 serves as an installation. The wall-mounting portion is provided on the main housing 13. In this way, the main housing 13 can be installed in a wall via the wall-mounting portion, thereby preventing problems with radiant cooling dew point control, preventing condensation during radiant cooling, and preventing the dehumidifier 1 from occupying indoor space. In addition, the compressor 20 can be arranged outdoors, solving the problem of high noise levels in conventional dehumidifiers 1. The inner partition 14 can play a partitioning role. The inner partition 14 is set in the main shell 13. The supply air channel 11 and the exhaust air channel 12 are formed on both sides of the inner partition 14, and the inner partition 14 is set between the first heat exchanger 30 and the second heat exchanger 50. In this way, the inner partition 14 can separate the supply air channel 11 and the exhaust air channel 12, realize multiple modes of the dehumidifier 1, improve the function of the dehumidifier 1, and can recover heat and cold, thereby improving the energy-saving effect of the dehumidifier 1.

[0051] In addition, if Figure 1 and Figure 4 As shown, the housing 10 also includes: an outdoor cover 15 and an indoor cover 16. The outdoor cover 15 is arranged on the outside of the main shell 13. The outdoor cover 15 is provided with a first outdoor air outlet 110 and a second outdoor air outlet 120, and the outdoor cover 15 selectively opens and closes the first outdoor air outlet 110 and the second outdoor air outlet 120. The indoor cover 16 is provided with a first indoor air outlet 111 and a second indoor air outlet 121, and the indoor cover 16 selectively opens and closes the first indoor air outlet 111 and the second indoor air outlet 121.

[0052] The outdoor cover 15 can be arranged on the outside of the main shell 13, so that the air intake and outlet of the outside of the main shell 13 can be controlled. The outdoor cover 15 is provided with a first outdoor air outlet 110 and a second outdoor air outlet 120, so that the fresh air from the outside can enter through the first outdoor air outlet 110 and the second outdoor air outlet 120, and the indoor air can also be discharged through the first outdoor air outlet 110 and the second outdoor air outlet 120. Moreover, the outdoor cover 15 can play a controlling role, and the first outdoor air outlet 110 and the second outdoor air outlet 120 can be selectively opened and closed by the outdoor cover 15, so that different modes of the dehumidifier 1 can be realized. Similarly, the indoor cover 16 can be arranged on the inner side of the main shell 13, so that the air intake and outlet on the inner side of the main shell 13 can be controlled. The indoor cover 16 is provided with a first indoor air outlet 111 and a second indoor air outlet 121, so that the indoor air can enter through the first indoor air outlet 111 and the second indoor air outlet 121, and the outdoor fresh air can also be discharged through the first indoor air outlet 111 and the second indoor air outlet 121. Moreover, the indoor cover 16 can play a controlling role, and the first indoor air outlet 111 and the second indoor air outlet 121 can be selectively opened and closed by the indoor cover 16, so that different modes of the dehumidifier 1 can be realized.

[0053] Of course, if Figure 1 As shown, an outdoor filter 17 and an indoor filter 18 are respectively provided on the outer and inner sides of the main housing 13. The outdoor cover 15 is covered on the outdoor filter 17, and the indoor cover 16 is covered on the indoor filter 18. The outdoor filter 17 and the indoor filter 18 can both play a filtering role. The outdoor filter 17 can prevent outdoor dust from entering the air duct, and the indoor filter 18 can prevent foreign matter such as hair and dust from entering the air duct. The outdoor cover 15 is covered on the outdoor filter 17, and the indoor cover 16 is covered on the indoor filter 18. This arrangement is reasonable and can better fix the outdoor cover 15 and the indoor cover 16. It can also make the outdoor cover 15 located at the outermost side of the dehumidifier 1 and the indoor cover 16 located at the innermost side of the dehumidifier 1, thereby facilitating the entry and exit of air.

[0054] In addition, if Figure 1As shown, the dehumidifier 1 further includes a protective screen 80 attached to the inner side of the outdoor filter 17, and / or an inner filter 90 disposed within the main housing 13 and positioned between the first and second fans 40 and 70 and the indoor filter 18. The protective screen 80 can provide protection. By attaching the protective screen 80 to the inner side of the outdoor filter 17, the protective screen 80 can prevent foreign objects such as animals from entering the air duct. The inner filter 90 can also provide filtering. By disposing the inner filter 90 within the main housing 13 and between the first and second fans 40 and 70 and the indoor filter 18, the inner filter 90 can deeply filter the air within the supply and exhaust ducts, effectively removing impurities from the air and ensuring fresher and healthier air entering the room. The inner filter 90 can be a HEAP filter.

[0055] Furthermore, if Figure 1 As shown, the dehumidifier 1 further includes an outdoor cushioning pad 100 and an indoor cushioning pad 200. The outdoor cushioning pad 100 is placed inside the outdoor filter 17, and the indoor cushioning pad 200 is placed outside the indoor filter 18. Both the outdoor cushioning pad 100 and the indoor cushioning pad 200 can provide cushioning. The outdoor cushioning pad 100 is placed inside the outdoor filter 17 and can abut against the outer wall. This can reduce the transmission of vibrations from the dehumidifier 1 to the outer wall during operation. The indoor cushioning pad 200 is placed outside the indoor filter 18 and can similarly abut against the inner wall during operation. This can reduce the transmission of vibrations from the dehumidifier 1 to the inner wall during operation. The outdoor cushioning pad 100 and the indoor cushioning pad 200 can both be rubber pads.

[0056] It should be noted that the main housing 13 is a soundproof and heat-insulating housing, and the inner partition 14 is a heat-insulating partition. By configuring the main housing 13 as a soundproof and heat-insulating housing, the main housing 13 can provide sound insulation, preventing noise generated by the dehumidifier 1 from being transmitted into the room and thus affecting user comfort. At the same time, the main housing 13 can also provide heat insulation, thereby preventing condensation when air enters the air supply duct 11 and the exhaust duct 12. Furthermore, the inner partition 14 is a heat-insulating partition, thereby further preventing condensation when air enters the air supply duct 11 and the exhaust duct 12.

[0057] Of course, if Figure 1As shown, the dehumidifier 1 further includes a compressor housing 300, which is disposed on the outside of the housing 10, and the compressor 20 is disposed within the compressor housing 300. The compressor housing 300 can serve as a mounting and fixing function. By placing the compressor 20 within the compressor housing 300, the position of the compressor 20 can be fixed, allowing the compressor 20 to operate more stably. In addition, by placing the compressor housing 300 on the outside of the housing 10, the compressor 20 can be fixed as a whole on the outside of the housing 10, thereby solving the problem of loud noise when the compressor 20 is operating.

[0058] In addition, Figure 2 As shown, the dehumidifier 1 further includes a four-way valve 400, which is connected at both ends of the compressor 20 and between the first heat exchanger 30 and the second heat exchanger 50. The four-way valve 400 can function as a selective on-off valve. The four-way valve 400 is connected at both ends of the compressor 20, so that the refrigerant needs to pass through the four-way valve 400 both when it is discharged from the compressor 20 and when it enters the compressor 20. In addition, the four-way valve 400 is connected between the first heat exchanger 30 and the second heat exchanger 50. In this way, the four-way valve 400 can control the flow direction of the refrigerant, thereby realizing different modes of the dehumidifier 1.

[0059] According to an optional embodiment of the present invention, Figure 5 As shown, the dehumidifier 1 further includes a controller, which is configured to:

[0060] S1, determining the operating mode of the dehumidifier 1;

[0061] S101: After confirming that the dehumidifier 1 is operating in the indoor dehumidification mode, the first outdoor air vent 110 and the second outdoor air vent 120 are controlled to be closed, and the first indoor air vent 111 and the second indoor air vent 121 are controlled to be open;

[0062] S102 , controlling the operation of the compressor 20 and the power-on reversal of the four-way valve 400 , and controlling the operation of the first fan 40 and the second fan 70 .

[0063] Specifically, the operating mode of the dehumidifier 1 is first determined. When it is determined that the dehumidifier 1 is operating in the indoor dehumidification mode, in summer and winter, the first outdoor air outlet 110 and the second outdoor air outlet 120 are closed. At this time, the four-way valve 400 is powered on and reversed, and the refrigerant is discharged from the compressor 20 into the first heat exchanger 30. The first heat exchanger 30 is a condenser at this time, and then passes through the throttling device to enter the second heat exchanger 50. The second heat exchanger 50 is an evaporator at this time. The indoor air is pushed into the exhaust duct by the second fan 70. The evaporator dehumidifies the indoor air and then blows it into the supply air duct through a closed loop. The cold air is heated by the condenser and then blown into the room to achieve dehumidification without cooling.

[0064] In addition, if Figure 6As shown, the controller is also configured to:

[0065] S111, after confirming that the dehumidifier 1 is operating in the fresh air dehumidification mode, the first outdoor air vent 110, the second outdoor air vent 120, the first indoor air vent 111 and the second indoor air vent 121 are controlled to open;

[0066] S112 , controlling the compressor 20 to operate, controlling the four-way valve 400 to power off, and controlling the first fan 40 and the second fan 70 to operate.

[0067] Specifically, the operating mode of the dehumidifier 1 is first determined. When it is determined that the dehumidifier 1 is operating in the fresh air dehumidification mode, in summer, the four-way valve 400 is powered off, and the gas refrigerant discharged from the compressor 20 passes through the four-way valve 400 into the second heat exchanger 50. The second heat exchanger 50 is a condenser at this time, and then passes through the throttling device to enter the first heat exchanger 30. The first heat exchanger 30 is an evaporator at this time. The first fan 40 is running, and the high-temperature fresh air outdoors enters the supply air duct. After being cooled and dehumidified by the evaporator, it is released into the room. The low-temperature air in the room is pushed into the exhaust duct by the second fan 70, and is discharged to the outside after the cold energy is recovered through the condenser, thereby realizing the air circulation of fresh air cooling and dehumidification.

[0068] In winter, the four-way valve 400 loses power, and the gas refrigerant discharged from the compressor 20 enters the second heat exchanger 50. At this time, the second heat exchanger 50 is a condenser, and then passes through the throttling device to enter the first heat exchanger 30. At this time, the first heat exchanger 30 is an evaporator. The first fan 40 is running, and the fresh air with higher humidity outdoors enters the supply air duct, is dehumidified by the evaporator and released into the room. The warm air in the room is pushed into the exhaust duct by the second fan 70, and is discharged to the outside through the condenser, realizing the air circulation of fresh air dehumidification.

[0069] Furthermore, if Figure 7 As shown, the controller is also configured to:

[0070] S121: After confirming that the dehumidifier 1 is operating in the indoor humidification mode, the first outdoor air vent 110 and the second outdoor air vent 120 are controlled to be open, and the first indoor air vent 111 and the second indoor air vent 121 are controlled to be closed;

[0071] S122, controlling the compressor 20 to operate and the four-way valve 400 to be powered off, and controlling the first fan 40 and the second fan 70 to operate until frost forms on one of the first heat exchanger 30 and the second heat exchanger 50 to a predetermined thickness;

[0072] S123, controlling the first outdoor air vent 110 and the second outdoor air vent 120 to be closed, and controlling the first indoor air vent 111 and the second indoor air vent 121 to be open;

[0073] S124 , controlling the compressor 20 to stop working and the four-way valve 400 to lose power, and controlling the first fan 40 and the second fan 70 to operate.

[0074] Specifically, the operation mode of the dehumidifier 1 is first determined. When it is determined that the dehumidifier 1 operates in the indoor humidification mode, in summer and winter, the first indoor air outlet 111 and the second indoor air outlet 121 are closed, the first outdoor air outlet 110 and the second outdoor air outlet 120 are opened, the four-way valve 400 is powered off, the first fan 40 and the second fan 70 are operated, and the compressor 20 operates at an appropriate frequency to cause frost on one of the first heat exchanger 30 and the second heat exchanger 50. The frosted heat exchanger is the evaporator. When the frost reaches a certain thickness, the first outdoor air outlet 110 and the second outdoor air outlet 120 are closed, the first indoor air outlet 111 and the second indoor air outlet 121 are opened, the four-way valve 400 is powered off, the compressor 20 is turned off, and the first fan 40 and the second fan 70 are operated to release the water vapor on the evaporator into the room, thereby achieving a humidification effect on the room.

[0075] Alternatively, as Figure 8 As shown, the controller is also configured to:

[0076] S131, after confirming that the dehumidifier 1 is operating in the fresh air mode, the first outdoor air vent 110, the second outdoor air vent 120, the first indoor air vent 111 and the second indoor air vent 121 are controlled to open;

[0077] S132: Control the compressor 20 to stop working and the four-way valve 400 to be powered off, and control the first fan 40 and the second fan 70 to run in the same direction to supply air to the room.

[0078] Specifically, first determine the operating mode of the dehumidifier 1. When it is determined that the dehumidifier 1 is operating in the fresh air mode, the indoor and outdoor temperatures and humidities are not much different, and outdoor fresh air can be injected. At this time, the first heat exchanger 30 and the second heat exchanger 50 are not working, and the first outdoor air outlet 110, the second outdoor air outlet 120, the first indoor air outlet 111 and the second indoor air outlet 121 are all opened. The first fan 40 and the second fan 70 are controlled to run in the same direction to increase the fresh air intake.

[0079] In addition, Figure 9 As shown, the controller is also configured to:

[0080] S141: After confirming that the dehumidifier 1 is operating in the fresh air heating mode, the first outdoor air vent 110, the second outdoor air vent 120, the first indoor air vent 111 and the second indoor air vent 121 are controlled to open;

[0081] S142 , controlling the operation of the compressor 20 and the power-on reversal of the four-way valve 400 , and controlling the operation of the first fan 40 and the second fan 70 .

[0082] Specifically, the operating mode of the dehumidifier 1 is first determined. When it is determined that the dehumidifier 1 is operating in the fresh air heating mode, in winter, the four-way valve 400 is powered on and reversed, and the refrigerant is discharged from the compressor 20 into the first heat exchanger 30. At this time, the first heat exchanger 30 is a condenser, and then passes through the throttling device to enter the second heat exchanger 50. At this time, the second heat exchanger 50 is an evaporator. The external cold air is pushed by the first fan 40 to flow through the condenser, and the condenser heats it and releases it into the room. The warm air in the room is pushed by the second fan 70 to flow through the evaporator, and the evaporator recovers the heat and discharges it to the outside, realizing the fresh air heating mode of the dehumidifier 1.
