[0033] The present invention provides a pet drying device based on a heat pump system, comprising: a first chamber 1, a drying component 4 and a second chamber 6.

[0034] Furthermore, the first chamber 1 is used to dry pets, and the second chamber 6 is used to process clothes. The drying component 4 is arranged between the first chamber 1 and the second chamber 6 and is controllably connected to the first chamber 1 and / or the second chamber 6.

[0035] Specifically, when the pet needs to be dried, the drying component 4 is connected to the first chamber 1 to dry the pet; when the clothes need to be processed, the drying component 4 is connected to the second chamber 6 to process the clothes; when the pet needs to be dried and the clothes need to be processed at the same time, the drying component 4 is connected to the first chamber 1 and the second chamber 6 at the same time, so that the pet can be dried while the clothes can be processed.

[0036] Further, the first chamber 1 is arranged upstream of the drying component 4 , and the second chamber 6 is arranged upstream of the drying component 4 .

[0037] In this embodiment, the drying assembly 4 is arranged at a relative position between the first chamber 1 and the second chamber 6. Specifically, the first chamber 1, the drying assembly 4 and the second chamber 6 are arranged in a vertical direction, the second chamber 6 is arranged at the bottom, and then the drying assembly 4 is arranged, and finally the first chamber 1 is arranged above the drying assembly 4, and the drying assembly 4 is selectively connected with the first chamber 1 and / or the second chamber 6 through the valve body.

[0038] like Figure 1 As shown, in this embodiment, the first chamber 1 is located at the top, the second chamber 6 is located at the bottom, and the drying component 4 is located between the first chamber 1 and the second chamber 6 .

[0039] Furthermore, the first chamber 1 is provided with an air inlet passage for taking air from the outside into the chamber and a circulating drying passage for drying the pet.

[0040] Specifically, the first chamber 1 is provided with a roll mat air inlet to draw air into the first chamber 1, and a circulating drying air path is provided around the first chamber 1 to dry the pet in all directions.

[0041] Advantageously, the air is mixed with the drying airflow to dry the pet, which can well control the temperature and ensure the drying effect.

[0042] Furthermore, the circulating drying air path is provided with a drying air inlet and a drying air outlet, the drying air inlet is connected to the air outlet of the drying component 4; the drying air outlet is connected to the air inlet of the drying component 4. By connecting the circulating drying air path with the drying component 4, air flow between the first chamber 1 and the drying component 4 can be achieved.

[0043] Furthermore, a first solenoid valve 21 is provided on the air path connecting the air outlet end of the drying component 4 to the first chamber 1, and a second solenoid valve 22 is provided on the air path connecting to the second chamber 6. The drying component 4 can be controlled to be connected to the first chamber 1 and / or the second chamber 6 through the first solenoid valve 21 and the second solenoid valve 22.

[0044] Furthermore, the drying component 4 includes a centrifugal fan 41 , and an air outlet of the centrifugal fan 41 is controllably connected to the first chamber 1 and / or the second chamber 6 via the first solenoid valve 21 and the second solenoid valve 22 .

[0045] Specifically, a first solenoid valve 21 is provided on the air path connected to the first chamber 1 at the air outlet end of the centrifugal fan 41, and a second solenoid valve 22 is provided on the air path connected to the second chamber 6. When the drying component 4 only needs to provide drying airflow to the first chamber 1, the first solenoid valve 21 is opened and the second solenoid valve 22 is closed, and the drying airflow enters the first chamber 1 after passing through the air outlet end of the centrifugal fan 41 to dry the pet in the first chamber 1; when the drying component 4 only needs to provide drying airflow to the second chamber 6, the first solenoid valve 21 is closed and the second solenoid valve 22 is opened, and the drying airflow enters the second chamber 6 through the air outlet end of the centrifugal fan 41 to process the clothes in the second chamber 6; when it is necessary to provide drying airflow to the first chamber 1 and the second chamber 6 at the same time, the first solenoid valve 21 and the second solenoid valve 22 are opened at the same time, and the drying airflow enters the first chamber 1 and the second chamber 6 through the air outlet end of the centrifugal fan 41 to dry the pet in the first chamber 1 while processing the clothes in the second chamber 6.

[0046] Furthermore, the drying component 4 also includes a heat pump system 42 and a lint filter 43. The lint filter 43 is arranged at the air inlet end of the heat pump system 42. The air outlet end of the heat pump system 42 is connected to the air inlet end of the centrifugal fan 41, and is used to provide hot air to the centrifugal fan 41; the air outlet end of the lint filter 43 is connected to the air inlet end of the heat pump system 42, and is used to filter the airflow entering the heat pump system 42.

[0047] Furthermore, a first one-way valve 31 is provided on the air path connecting the drying air outlet with the air inlet end of the lint filter 43 , so as to allow the drying air flow in the first chamber 1 to flow into the lint filter 43 .

[0048] Furthermore, a second one-way valve 32 is provided on the air passage connecting the air inlet end of the lint filter 43 and the second chamber 6 , for passing the drying air flow in the second chamber 6 into the air inlet end of the lint filter 43 .

[0049] Specifically, the drying airflow generated by the heat pump system 42 enters the centrifugal fan 41. When it is necessary to dry the pet in the first chamber 1, the first solenoid valve 21 is opened and the second solenoid valve 22 is closed. After the drying airflow passes through the centrifugal fan 41, it passes through the connecting air path between the centrifugal fan 41 and the first chamber 1, and enters the circulating drying air path set in the first chamber 1 from the drying air flow inlet, and then dries the pet in the first chamber 1. At the same time, the air from the suction air inlet 11 on the two side walls of the first chamber 1 enters the drying chamber due to the suction and rolling action of the first chamber 1. The air is mixed with the drying airflow to dry the pet in the drying chamber. After drying, the airflow is discharged through the drying airflow outlet, and enters the air inlet end of the lint filter 43 through the air path between the drying airflow outlet and the lint filter 43. At this time, the first one-way valve 31 is opened, and the second one-way valve 32 is closed. The airflow filtered by the lint filter 43 enters the heat pump system 42 and enters the next drying cycle.

[0050] Specifically, when it is necessary to process the clothes in the second chamber 6, the first solenoid valve 21 is closed and the second solenoid valve 22 is opened. The drying airflow passes through the centrifugal fan 41 and then passes through the connecting air path between the centrifugal fan 41 and the first chamber 1 to enter the second chamber 6 to dry the clothes in the second chamber 6. After drying, the drying airflow passes through the air path between the second chamber 6 and the lint filter 43 and enters the air inlet end of the lint filter 43. At this time, the first one-way valve 31 is closed and the second one-way valve 32 is opened. The airflow filtered by the lint filter 43 enters the heat pump system 42 and enters the next drying cycle.

[0051] Specifically, in the heat pump drying process, the compressor compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, and then transfers the high-temperature and high-pressure refrigerant to the evaporator, where the refrigerant evaporates and absorbs heat energy in the air, causing the air temperature to rise and the humidity to decrease. Then, the refrigerant transfers the absorbed heat energy to the condenser, where the refrigerant in the condenser cools and condenses, releasing the absorbed heat energy, and then enters the compressor again, repeating the cycle. Therefore, in conjunction with the gas circulation of the heat pump system 42, a solenoid valve and a one-way valve are provided between the first chamber 1 and the second chamber 6 and the drying assembly 4 to achieve the reciprocating circulation of the airflow between the three.

[0052] In this embodiment, the first chamber 1 is a pet drying chamber, the second chamber 6 is a clothes drying processing device, and a drying component 4 is arranged between the two.

[0053] Specifically, when the pet needs to be dried, the pet is placed in the first chamber 1, the drying component 4 is turned on, and the drying of the pet begins.

[0054] Specifically, the drying process starts, the heat pump system 42 starts to work, the compressor compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, and then transfers the high-temperature and high-pressure refrigerant to the evaporator, where the refrigerant evaporates, absorbs heat energy in the air, and increases the air temperature and reduces the humidity. The output drying airflow enters the centrifugal fan 41, because the pet is being dried at this time, therefore, the first solenoid valve 21 on the air path connected to the first chamber 1 at the outlet end of the centrifugal fan 41 is opened, and the second solenoid valve 22 on the air path connected to the second chamber 6 is closed, and the drying airflow enters from the air inlet end of the centrifugal fan 41, and then blows out from the air outlet end, enters the drying airflow inlet through the air path connected to the first chamber 1, and then enters the drying chamber through the circulating drying air path set in the first chamber 1, and dries the pet inside.

[0055] Specifically, while the drying airflow enters from the drying airflow inlet, the air inlet 11 on the side wall of the first chamber 1 draws the air into the drying chamber by utilizing the negative pressure generated by the drying airflow in the chamber. After the drying airflow and the air are mixed, the pet is dried. The airflow after drying the pet is discharged from the drying airflow outlet provided on the first chamber 1, and enters the lint filter 43 through the air path connecting the first chamber 1 with the air inlet end of the lint filter 43 in the drying component 4. At this time, the first one-way valve 31 is opened and the second one-way valve 32 is closed. The drying airflow passes through the filtering effect of the lint filter 43, and the pet dander in the drying airflow is filtered out. Then the airflow enters the heat pump system 42 through the air outlet end of the lint filter 43, and enters the next drying process.

[0056] In this embodiment, the second chamber 6 is a clothes drying treatment device. When clothes need to be dried, the clothes are placed in the second chamber 6.

[0057] Specifically, the drying process starts, the heat pump system 42 starts to work, the compressor compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, and then transfers the high-temperature and high-pressure refrigerant to the evaporator, where the refrigerant evaporates, absorbs heat energy in the air, and increases the air temperature and reduces the humidity. The output dry airflow enters the centrifugal fan 41, and at this time, the clothes are being dried. Therefore, the second solenoid valve 22 on the air path connected to the second chamber 6 at the outlet end of the centrifugal fan 41 is opened, and the first solenoid valve 21 on the air path connected to the first chamber 1 is closed. The dry airflow enters from the air inlet end of the centrifugal fan 41, and then blows out from the outlet end, and enters the second chamber 6 through the air path connected to the second chamber 6 to dry the clothes inside.

[0058] Specifically, the airflow after drying the clothes enters the lint filter 43 from the air passage connected to the air inlet end of the lint filter 43 in the drying assembly 4 through the second chamber 6. At this time, the second one-way valve 32 is opened and the first one-way valve 31 is closed. The drying airflow is filtered by the lint filter 43, and the clothing lint in the drying airflow is filtered out. Then, the airflow enters the heat pump system 42 through the air outlet end of the lint filter 43, and enters the next drying process.

[0059] When the pet needs to be dried and the clothes need to be processed at the same time, the first solenoid valve 21 and the second solenoid valve 22 are opened at the same time, and the drying airflow enters the first chamber 1 and the second chamber 6 through the connecting air passage between the drying component 4 and the first chamber 1 and the second chamber 6 to dry the pets and clothes in the chambers.

[0060] Placing the pet drying device and the clothes drying processing device together saves space. Using the heat pump system 42 to dry the pet can better control the hot air to slowly enter the chamber.

[0061] In this embodiment, an automatic delivery component 5 is further provided for delivering the required additives into the second chamber 6 .
