[0029] When using an exhaust fan to ventilate the bathroom, in order to retain the energy contained in the air to be replaced in the bathroom indoors, the present application proposes a ventilation system, which includes an exhaust air energy absorption unit 10, a temperature adjustment unit, and an energy transmission unit; wherein, the exhaust air energy absorption unit 10 is used for ventilating the indoor air and absorbing the energy contained in the replaced air, and transferring the absorbed energy to the temperature adjustment unit through the energy transmission unit, and the temperature adjustment unit can use the energy absorbed by the exhaust air energy absorption unit 10 to adjust the indoor temperature.

[0030] In this way, through the ventilation system of the present application, the energy contained in the air to be replaced in the bathroom can be retained indoors, avoiding energy loss caused by direct discharge. Especially during the cooling in summer or heating in winter, while ventilating the bathroom to remove odors, the "cooling capacity" or "heat quantity" contained in the air to be replaced in the bathroom can be retained indoors, avoiding energy waste caused by direct discharge.

[0031] When ventilating the bathroom, the air temperature in the bathroom is usually between 10 and 28 degrees. The air in this temperature range contains high-quality low-grade heat energy. For a heat pump type air conditioner, whether it is used for refrigeration or heating, this part of low-grade heat energy is a high-quality resource with high heat exchange efficiency. In view of this, the temperature adjustment unit of the present application can be set as a heat pump type air conditioner 20; the energy transmission unit can be set in various possible forms according to needs, as long as it can reliably transfer the energy absorbed by the exhaust air energy absorption unit 10 from the air to be replaced to the temperature adjustment unit. Since the temperature adjustment unit is set as a heat pump type air conditioner 20 as described above, correspondingly, the energy transmission unit can be set as a refrigerant pipe 30.

[0032] The ventilation and energy absorption unit 10 can be configured into a variety of possible forms as needed, as long as it can absorb the energy contained in the indoor air to be replaced; preferably, the ventilation and energy absorption unit 10 can be configured to include a ventilation device, an energy absorption device and a drainage device; wherein the ventilation device is used to discharge the indoor air to be replaced to the outside, the energy absorption device is used to absorb the energy contained in the air to be replaced and transfer the absorbed energy to the heat pump air conditioner 20 through the refrigerant pipe 30, and the drainage device is used to discharge the condensed water generated by the energy absorption device in the process of absorbing energy to the outside.

[0033] The ventilation device, energy absorption device and drainage device can be arranged in various possible forms according to the needs, as long as they can complete their respective functions. Preferably, the ventilation device can be configured to include a ventilation fan 11 and a ventilation pipe 12; wherein the ventilation fan 11 is used to absorb the indoor air to be replaced and discharge this part of the air to be replaced to the outside through the ventilation pipe 12; the energy absorption device can be configured to include a heat exchange coil 13, wherein the heat exchange coil 13 is located between the ventilation fan 11 and the ventilation pipe 12 and is connected to the refrigerant pipe 30, the heat exchange coil 13 can absorb the energy contained in the air to be replaced and transfer the absorbed energy to the aforementioned heat pump air conditioner 20 through the refrigerant pipe 30 connected to the heat exchange coil 13; the drainage device can be configured to include a condensate receiving pan 14 and a condensate drain pipe 15, wherein the condensate receiving pan 14 is located between the heat exchange coil 13 and the ventilation fan 11 and is connected to the condensate drain pipe 15, the condensate receiving pan 14 is mainly used to collect the condensate generated in the process of the heat exchange coil 13 absorbing energy from the air to be replaced and discharge it to the outside through the condensate drain pipe 15 connected to the condensate receiving pan 14.

[0034] In the process of ventilating the bathroom, in order to ensure that the energy absorbing device can fully absorb the energy contained in the air to be ventilated, an isolation device can be further provided in the ventilation energy absorbing unit 10; the isolation device can be specifically provided according to the structure of the energy absorbing device, and in combination with the structural characteristics of the above-mentioned energy absorbing device including the heat exchange coil 13, the isolation device can be provided on the top of the heat exchange coil 13, including an isolation plate 16, an isolation plate rotating shaft 17 and an isolation plate driving device 18; Figure 1 , Figure 2 As shown, the isolation plate 16 can be designed as a circular plate arranged on the top of the heat exchange coil 13, and the diameter of the isolation plate 16 is set to be the same as the inner diameter of the heat exchange coil 13; correspondingly, the isolation plate rotating shaft 17 is set on the radial diameter of the isolation plate 16, and the isolation plate driving device 18 is set at the end of the isolation plate rotating shaft 17. In the process of ventilation, when it is necessary to absorb the energy contained in the air to be ventilated, that is, the ventilation system is in the energy recovery ventilation state, as shown in FIG. Figure 1As shown, at this time, the circular partition plate 16 is in a "horizontal" state. Since the diameter of the circular partition plate 16 is the same as the inner diameter of the heat exchange coil 13, the partition plate 16 can effectively prevent the air flow of the air to be exchanged from flowing through the gap between the heat exchange coils 13. At this time, the air flow of the air to be exchanged can only pass through the heat exchange coils 13 for sufficient heat exchange and then be discharged outdoors through the air exchange pipe 12; during the ventilation process, when it is not necessary to absorb the energy contained in the air to be exchanged, that is, when the ventilation system is in a single ventilation mode, the partition plate 16 can be driven by the partition plate driving device 18 to rotate around the partition plate rotation axis 17 to a position perpendicular to the ventilation fan 11 in the vertical direction, as Figure 3 shown. At this time, the partition plate 16 is in a "vertical" state, and the air flow of the air to be exchanged can directly flow through the gap between the heat exchange coils 13, that is, the air flow of the air to be exchanged is no longer blocked by the partition plate 16 but is directly discharged outdoors through the air exchange pipe 12.

[0035] The heat pump type air conditioner 20 as the temperature adjustment unit mainly includes two major components: a heat pump device 21 and an air conditioner device 22; among them, the heat pump device 21 that realizes energy transfer and utilization can compress and do work on the energy absorbed by the ventilation energy absorption unit 10 transmitted from the refrigerant pipe 30 and transmit the energy after compression work to the air conditioner device 22 through the refrigerant pipe 30. In the air conditioner device 22, the indoor air exchanges heat with the energy after compression work by the heat pump device 21, and finally sends the energy after compression work by the heat pump device 21 into the room, so as to achieve the effect of temperature adjustment.

[0036] In order to better exert the function of the heat pump device 21, further, the heat pump device 21 can be set to include a compressor 211, an expansion valve 212, and a four-way valve 213; among them, the compressor 211 is the power source for the entire heat pump type air conditioner 20 to realize refrigeration and heating. It can compress and do work on the energy absorbed by the ventilation energy absorption unit 10 transmitted from the refrigerant pipe 30 and transmit the energy after compression work to the air conditioner device 22 through the refrigerant pipe 30; during the work of the compressor 211, the expansion valve 212 can provide a carrier for the energy generated after the compression work of the compressor 211, such as high-temperature and high-pressure gas or low-temperature and low-pressure gas-liquid mixture. These energy carriers carry the energy generated after the compression work of the compressor 211 and are transmitted to the air conditioner device 22 through the refrigerant pipe 30; and the four-way valve 213 is mainly used to switch the working mode of the heat pump type air conditioner 20 to switch the heat pump type air conditioner 20 between the refrigeration mode and the heating mode.

[0037] As the specific execution device for the air conditioner 22 to adjust the indoor temperature in the heat pump type air conditioner 20, it mainly includes an air conditioner heat exchange coil 221 and a circulation fan 222; among them, the energy after the compressor 211 compresses and does work is transported to the air conditioner heat exchange coil 221 through the refrigerant pipe 30, and heat exchange is carried out with the indoor air in the air conditioner heat exchange coil 221; the function of the circulation fan 222 is to promote the continuous circulation of the indoor air. For example, the circulation fan 222 can send the indoor air into the air conditioner heat exchange coil 221 to carry out heat exchange with the energy after the compressor 211 compresses and does work, and quickly distribute the energy exchanged by the air conditioner heat exchange coil 221 to the indoor to adjust the indoor temperature.

[0038] In addition, when the indoor air exchanges heat with the energy after the compressor 211 compresses and does work in the air conditioner heat exchange coil 221, condensate will be generated in the air conditioner heat exchange coil 221. In order to drain the condensate outdoors in time, preferably, the air conditioner device 22 can be set to further include an air conditioner condensate receiving tray 223 and an air conditioner condensate drain pipe 224; among them, the air conditioner condensate receiving tray 223 is located below the air conditioner heat exchange coil 221 and is connected to the air conditioner condensate drain pipe 224. As Figure 1 shown, the air conditioner condensate receiving tray 223 is used to collect the condensate generated during the heat exchange process of the air conditioner heat exchange coil 221 and drain it outdoors through the air conditioner condensate drain pipe 224.

[0039] According to another aspect of the present application, a toilet is also proposed, and the toilet includes the ventilation system described above.

[0040] Next, in combination with Figures 1 - 3, the working process of the ventilation system of the present application will be explained in detail:

[0041] In summer, normal cooling service is required for the toilet. At this time, the heat pump air conditioner 20 of the ventilation system is set to the cooling mode through the four-way valve 213, and the heat pump air conditioner 20 normally provides cooling service for the toilet. When ventilation and air change are required for the toilet, the air change and energy absorption unit 10 of the ventilation system starts to work. At this time, the ventilation system is in the energy recovery and air change working condition. Specifically, the exhaust fan 11 absorbs the indoor air containing "cooling capacity" to the air change port 19. At this time, the circular partition plate 16 is in the "horizontal" state. The indoor air can only pass through the heat exchange coil 13 for sufficient heat exchange and then be discharged to the outside through the air change pipe 12. At this time, the heat exchange coil 13 is used as a condenser, which can absorb the "cooling capacity" contained in the indoor air and transfer it to the compressor 211 of the heat pump device 21 through the refrigerant pipe 30. The condensed water generated during the process of the heat exchange coil 13 absorbing the "cooling capacity" is collected by the condensed water receiving tray 14 and then discharged to the outside through the condensed water drain pipe 15. During the process of the compressor 211 compressing and doing work on the "cooling capacity" transferred through the refrigerant pipe 30, part of the gaseous refrigerant in the refrigerant pipe 30 is liquefied by the expansion valve 212 to generate a low-temperature and low-pressure gas-liquid mixed refrigerant, which is used to carry the "cooling capacity" after being compressed and worked on by the compressor 211 and is sent to the air conditioner heat exchange coil 221 of the air conditioner device 22 through the refrigerant pipe 30. At the same time, the circulation fan 222 sends the indoor air to the air conditioner heat exchange coil 221 through the air inlet 225 of the air conditioner device 22. In the air conditioner heat exchange coil 221, the "cooling capacity" after being compressed and worked on by the compressor 211 exchanges heat with the indoor air, and the circulation fan 222 quickly and evenly distributes the "cooling capacity" after being exchanged by the air conditioner heat exchange coil 221 to the indoor through the air outlet 226 of the air conditioner device 22 to reduce the indoor temperature. The condensed water generated during the process of the air conditioner heat exchange coil 221 absorbing the "cooling capacity" is collected by the air conditioner condensed water receiving tray 223 and then discharged to the outside through the air conditioner condensed water drain pipe 224. In the air conditioner heat exchange coil 221, the gas-liquid mixed refrigerant used to carry the "cooling capacity" becomes all gaseous after heat exchange and then enters the heat exchange coil 13 through the expansion valve 212 and the refrigerant pipe 30 to form a circulating cooling.

[0042] In winter, normal heating service is required for the bathroom. At this time, the heat pump type air conditioner 20 of the ventilation system is set to the heating mode through the four-way valve 213, and the heat pump type air conditioner 20 normally provides heating service for the bathroom. When ventilation and air change are required for the bathroom, the air change and energy absorption unit 10 of the ventilation system starts to work. At this time, the ventilation system is in the energy recovery ventilation condition. Specifically, the ventilation fan 11 absorbs the indoor air containing "heat" to the air change port 19. At this time, the circular isolation plate 16 is in the "horizontal" state. The indoor air can only pass through the heat exchange coil 13 for sufficient heat exchange and then be discharged to the outside through the air change pipe 12. At this time, the heat exchange coil 13 is used as an evaporator, which can absorb the "heat" contained in the indoor air and transfer it to the compressor 211 of the heat pump device 21 through the refrigerant pipe 30. During the process of the compressor 211 compressing and doing work on the "heat" transferred through the refrigerant pipe 30, part of the gas-liquid mixed refrigerant in the refrigerant pipe 30 is vaporized by the expansion valve 212 to generate high-temperature and high-pressure gaseous refrigerant, which is used to carry the "heat" after being compressed and worked on by the compressor 211, and is sent to the air conditioner heat exchange coil 221 of the air conditioner device 22 through the refrigerant pipe 30. At the same time, the circulation fan 222 sends the indoor air to the air conditioner heat exchange coil 221 through the air inlet 225 of the air conditioner device 22. In the air conditioner heat exchange coil 221, the "heat" after being compressed and worked on by the compressor 211 exchanges heat with the indoor air, and the circulation fan 222 quickly and evenly distributes the "heat" after being exchanged by the air conditioner heat exchange coil 221 to the indoor through the air outlet 226 of the air conditioner device 22 to raise the indoor temperature. In the air conditioner heat exchange coil 221, the high-temperature and high-pressure gaseous refrigerant used to carry the "heat" becomes gas-liquid mixed refrigerant after heat exchange, and then enters the heat exchange coil 13 through the expansion valve 212 and the refrigerant pipe 30 to form a circulating heating system.

[0043] In spring, autumn or other periods with suitable temperatures, the bathroom only needs ventilation and air change without cooling or heating. The ventilation system is in the single air change condition, and the heat pump type air conditioner 20 stops running. At this time, the circular isolation plate 16 is in the "vertical" state, as Figure 3 shown. The air flow of the air to be changed in the bathroom can directly flow through the gap between the heat exchange coils 13, that is, the air flow of the air to be changed is no longer blocked by the isolation plate 16 but is directly discharged to the outside through the air change pipe 12.

[0044] According to the technical solution of the present application, a bathroom and its ventilation system are proposed. When the ventilation system ventilates and changes the air in the bathroom, it can effectively absorb and utilize the energy contained in the air to be changed in the bathroom, avoiding energy waste and effectively improving the living experience. It can be foreseen that the ventilation system of the present application is not only applicable to the bathroom, but also can be extended to any house that still needs cooling or heating while ventilating and changing the air.

Within the scope of the technical concept of the present application, various simple modifications can be made to the technical solutions of the present application, and these simple modifications all fall within the protection scope of the present application.

[0046] In addition, it should be noted that, in the case of no conflict, the various specific technical features described in the above specific embodiments can be combined in any appropriate manner. To avoid unnecessary repetition, the present application will not separately describe various possible combination manners.

[0047] In addition, any combination can be made between various different embodiments of the present application, as long as it does not violate the idea of the present application, it should also be regarded as the content disclosed by the present application.
