Description

Technical Field

[0001] This utility model relates to the field of pet drying boxes, specifically to an energy-saving pet drying box. Background Technology

[0002] Currently, pet drying boxes are used to dry pets' fur. A reference can be made to the Chinese invention patent application publication number CN120391355A, "A Heat Exchange System for a Dual-Channel Pet Drying Box." This "Heat Exchange System for a Dual-Channel Pet Drying Box" includes a box body, a refrigeration system, a rear air supply device, and a heating device. The refrigeration system includes an evaporative heat exchange device. When the rear air supply device is working, it drives the air inside the box to flow through the evaporative heat exchange device. The air is cooled at the evaporative heat exchange device, and the moisture in the air condenses on the evaporative heat exchange device. The heat from the condenser is dissipated to the outside through the airflow generated by the exhaust fan. In other words, the main function of the refrigeration system is to reduce the humidity inside the box, shortening the drying time for the pet. To prevent the pet from getting cold and uncomfortable, the heating device heats the air cooled by the evaporative heat exchange device, making the temperature of the air blown into the box relatively high, thus making the temperature inside the box suitable for the pet. Therefore, the pet drying box includes two high-power components: the refrigeration system and the heating device, resulting in relatively high power consumption and energy saving. Improvements are necessary. Summary of the Invention

The refrigerant circulation system is provided with a heat exchanger for heating the water in the water tank. The heat exchanger is located in the water tank, and the exhaust port of the compressor is connected to the condenser through the heat exchanger.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] This utility model relates to an energy-saving pet drying box, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the device includes a housing 1 and a refrigerant circulation system. The housing 1 contains an inner liner 11 for housing a pet. The front end of the inner liner 11 has a pet inlet / outlet. The housing 1 is hinged to a door 12 for opening and closing the pet inlet / outlet. Figure 5 As shown, the refrigerant circulation system includes a compressor 2 and a condenser 3, such as Figures 1 to 4 As shown, a water tank 5 for heat transfer to the inner liner 11 is provided between the casing 1 and the inner liner 11; that is, the water tank 5 is concealed between the outer wall of the inner liner 11 and the inner wall of the casing 1. Figure 2 and Figure 5 As shown, the refrigerant circulation system includes a heat exchanger 51 for heating the water in the water tank 5. The heat exchanger 51 is located inside the water tank 5. The exhaust port 201 of the compressor 2 is connected to the condenser 3 through the heat exchanger 51. The heat exchanger 51 includes a tortuous tube body. Figure 5 As shown, the refrigerant circulation system also includes an evaporator 4 and a throttling valve 7.

[0020] like Figure 5 As shown, when the refrigerant circulation system is working, compressor 2 outputs high-temperature, high-pressure gaseous refrigerant through discharge port 201. Since discharge port 201 of compressor 2 is connected to condenser 3 through heat exchanger 51, the refrigerant discharged from discharge port 201 first flows through heat exchanger 51. Heat exchanger 51 generates heat to heat the water in water tank 5, and the water simultaneously cools the refrigerant flowing through heat exchanger 51. The refrigerant and water are isolated by the tubes of heat exchanger 51, and then the refrigerant flows to condenser 3. Figure 2 As shown, a cooling fan 31 is provided at the rear of the condenser 3. The condenser 3 is located at the air inlet of the cooling fan 31. The cooling fan 31 blows air backward, causing outside air to flow through the condenser 3, thereby further cooling the refrigerant flowing through the condenser 3. Figure 5 As shown, the refrigerant then passes through the expansion valve 7 to the evaporator 4. After passing through the expansion valve 7, the refrigerant becomes a low-temperature, low-pressure gas-liquid mixture. As the refrigerant flows through the evaporator 4, it evaporates and absorbs heat, causing moisture in the air flowing over the outer surface of the evaporator 4 to condense. The refrigerant then flows back to the compressor 2, thus forming a refrigerant cycle. Figure 3 As shown by the dotted arrow, when the dehumidifier 8 is working, it blows air downwards into the interior of the inner liner 11. Then, the airflow flows from the lower rear end of the inner liner 11 into the air duct between the inner liner 11 and the housing 1. The evaporator 4 and the heating device 9 are located in the aforementioned air duct. The airflow is cooled by the evaporator 4 and then heated by the heating device 9. The airflow is then drawn back into the dehumidifier 8, thus forming an air circulation within the housing 1 (which can be understood as an external air circulation for the inner liner 11). This prevents the airflow blowing into the inner liner 11 from being too cold and causing discomfort to the pet.

[0021] Since the water tank 5 is located between the casing 1 and the inner liner 11, and the water in the water tank 5 is heated, some of the heat emitted by the water tank 5 is transferred to the inner liner 11, causing the interior of the inner liner 11 to heat up. In other words, some of the heat energy that the high-temperature and high-pressure gaseous refrigerant output by the compressor 2 needs to dissipate is transferred to the interior of the inner liner 11. The cooling fan 31 and the water tank 5 work together to cool the refrigerant, which on the one hand makes the refrigerant cool more effectively, which is conducive to the effective operation of the evaporator 4 to absorb heat, and on the other hand makes the interior of the inner liner 11 heat up effectively. This avoids relying entirely on the heating device 9 to heat the circulating airflow to heat the interior of the inner liner 11, which is conducive to energy saving. During daily use of the pet drying box, because the water temperature in the water tank 5 is relatively high, when the pet drying box is not in use, the heat of the water in the water tank 5 can still be transferred to the inner liner 11. This is equivalent to the water in the water tank 5 playing a role in keeping the inner liner 11 warm (which can also be understood as a "preheating effect"). When a pet needs to use the pet drying box again in a short period of time, the heating device 9 and the dehumidifying fan 8 can be turned on to shorten the time it takes for the inner liner 11 to heat up to a suitable temperature. After the pet enters the inner liner 11, the refrigerant circulation system is turned on to dehumidify.

[0022] Furthermore, such as Figure 2 and Figure 4 As shown, water tanks 5 are distributed on the left and right sides of the inner liner 11. That is, there are two water tanks 2, and correspondingly, there are two heat exchangers 51. The water tank 5 located on the left side of the inner liner 11 is positioned between the left outer wall panel 101 of the housing 1 and the left wall of the inner liner 11, while the water tank 5 located on the right side of the inner liner 11 is positioned between the right outer wall panel 102 of the housing 1 and the right wall of the inner liner 11. Figure 5 As shown, the two heat exchangers 51 can be connected in series. The high-temperature and high-pressure gaseous refrigerant output from the exhaust port 201 of the compressor 2 passes through the two heat exchangers 51 in sequence before reaching the condenser 3. The layout of the water tank 5 is conducive to heating the inner tank 11 on both sides and to heating the inner tank 11 more evenly. The water in the water tank 5 also has a good heat preservation effect on the inner tank 11. Since the evaporator 4 is located on the rear side of the inner tank 11 and the water tank 5 is distributed on the left and right sides of the inner tank 11, the evaporator 4 can avoid significantly absorbing the heat of the water tank 5.

[0023] Furthermore, such as Figure 6As shown, water tank 5 is equipped with a drain solenoid valve 5011 and an inlet solenoid valve 502 for connecting to a tap water pipe. That is, water tank 5 is connected to a tap water pipe via the inlet solenoid valve 502. Water tank 5 contains a water tank temperature sensor 503, which is mounted on the wall of water tank 5 and extends into the interior of water tank 5. Therefore, water tank temperature sensor 503 can monitor the water temperature inside water tank 5. Since high water temperatures can easily cause scale formation on the surface of heat exchanger 51, affecting its operation, when heat exchanger 51 raises the water temperature in water tank 5 to approximately 50 degrees Celsius, the controller activates the water temperature sensor... The controller controls the drain solenoid valve 5011 to open, draining the water in the water tank 5 through the drain solenoid valve 5011. At the same time, the controller controls the inlet solenoid valve 502 to open, allowing tap water to flow into the water tank 5 through the inlet solenoid valve 502, thus changing the water in the water tank 5. This lowers the water temperature in the water tank 5, reducing scale formation and also helping to cool the refrigerant flowing through the heat exchanger 51. When the water tank temperature sensor 503 detects that the water temperature in the water tank 5 has dropped to about 35 degrees Celsius, the controller controls the drain solenoid valve 5011 and the inlet solenoid valve 502 to close, preventing the water temperature in the water tank 5 from dropping too much and wasting heat energy, and also preventing significant waste of tap water.

[0024] Furthermore, such as Figure 3 and Figure 4 As shown, a drip tray 6 is provided on the lower side of the inner liner 11. Specifically, a support grid for the pet to stand on is provided at the lower end of the inner liner 11, and the drip tray 6 is located below the support grid. Therefore, water flowing down the pet's body while drying in the inner liner 11 can be collected by the drip tray 6, as can the pet's urine. Thus, the drip tray 6 will contain urine, hair, and other debris. Figure 6 As shown, the water tank 5 is connected to a drain pipe 501 via a drain solenoid valve 5011 for flushing water into the drip tray 6. Figure 4 As shown, for example, the upper end of the drain pipe 501 can be connected to the bottom of the water tank 5 through the drain solenoid valve 5011, and the lower end of the drain pipe 501 can extend into the edge of the liquid receiving tray 6. So when the drain solenoid valve 5011 is opened, the water in the water tank 5 can be discharged into the liquid receiving tray 6 through the drain pipe 501. The water flow washes the liquid receiving tray 6, which can wash away the dirt in the liquid receiving tray 6. The lower rear end of the liquid receiving tray 6 is connected to a sewage pipe.

[0025] Furthermore, such as Figure 2 and Figure 4 As shown, the water tank 5 is attached to the outer wall of the inner liner 11. The water in the water tank 5 transfers heat to the water tank 5, and the water tank 5 can directly transfer heat to the outer wall of the inner liner 11. The temperature of the inner liner 11 wall increases, which in turn increases the internal temperature of the inner liner 11.
