DETAILED DESCRIPTION

[0024] First of all, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can adjust them as needed in order to adapt to specific application occasions. For example, the clothes treatment device of the present application can be a dryer, or a variety of clothes treatment devices with drying function such as washer-dryer.

[0025] Secondly, it needs to be explained that in the description of the present application, the terms indicating the direction or position relationship of "inner", "outer" and the like are based on the direction or position relationship shown in the drawings, which is only for the convenience of description, and is not intended to indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0026] In addition, it also needs to be explained that in the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside two components. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] The existing dryer, washer-dryer and other clothes treatment devices with drying function, when the condensing drying system dries the clothes in the clothes containing cavity, since the clothes containing cavity is communicated with the clothes taking and placing opening, the temperature of the sealing door arranged at the clothes taking and placing opening will also rise sharply, causing the sealing door to have too high temperature. The sealing door with too high temperature is prone to cause scalding to the user on the one hand, and on the other hand, it will cause the temperature of the surrounding environment to rise sharply, especially in hot summer, which will cause the temperature of the environment to be too high.

[0028] In addition, the condensing drying system cools and dehumidifies the humid hot air sucked from the clothes accommodating cavity by continuously supplying the condensing water and directly contacting the supplied condensing water with the sucked humid hot air. After the humid hot air is cooled and dehumidified by directly contacting with the condensing water, the air in the condensing drying system still contains a large amount of water. When the air is heated and supplied into the clothes accommodating cavity to dry the clothes, the hot air in the clothes accommodating cavity contains a large amount of water, and the drying efficiency is low. The drying time often exceeds 4 hours, and the drying time is long and the energy consumption is high.

[0029] To solve the above problems, the present application provides a clothes processing device. The clothes processing device comprises a machine body, a clothes accommodating cavity arranged in the machine body, a sealing door arranged on the clothes accommodating cavity, a condensing drying system arranged in the machine body and connected with the clothes accommodating cavity, and a cooling cavity arranged in the sealing door. The sealing door is provided with a first water inlet and a water outlet which are in communication with the cooling cavity. The condensing drying system is provided with a water supply pipe. A water supply end of a water supplement pipe is in communication with the water supply pipe. A water outlet end of the water supplement pipe is in communication with the first water inlet. The water supplement pipe is arranged to supply the cooling water into the cooling cavity of the sealing door when the condensing drying system dries the clothes in the clothes accommodating cavity of the machine body. The cooling water in the cooling cavity can absorb a large amount of heat of the sealing door, slow down the temperature rise of the sealing door, and take away the heat after the cooling water in the cooling cavity is discharged from the water outlet. Thus, the user can be prevented from being scalded by the high-temperature sealing door, and the surrounding environment temperature can be prevented from being too high due to the high-temperature sealing door in summer. In addition, the low-temperature sealing door can condense the water in the hot air supplied by the condensing drying system. The hot air passing through the surface of the sealing door is more dry, and the drying efficiency is higher when the hot air contacts the clothes. Thus, the drying time can be shortened, and the energy consumption can be reduced.

[0030] The preferred technical scheme of the clothes processing device of the present application will be described below with reference to the drawings.

[0031] Referring to Figures 1-3 , Figure 1 is a schematic view of the embodiment of the clothes processing device provided by the present application when water is supplied, Figure 2 is a schematic view of the embodiment of the clothes processing device when water supply is stopped, Figure 3 is a schematic view of the embodiment of the clothes processing device provided by the present application when water is drained. As Figures 1-3As shown, the clothes treating apparatus of the present application specifically comprises a machine body 100, a sealing door 200, a condensing drying system 300 and a water replenishing pipe 400, the machine body 100 is formed with a clothes accommodating cavity 170 for treating clothes, the machine body 100 is further provided with a clothes loading / unloading opening 130 which is in communication with the clothes accommodating cavity 170, the condensing drying system 300 is arranged in the machine body 100 and used for drying clothes in the clothes accommodating cavity 170, the sealing door 200 is openably arranged at the clothes loading / unloading opening 130 and is formed with a cooling cavity 230, the sealing door 200 is provided with a first water inlet 231 and a water outlet 232 which are in communication with the cooling cavity 230, the first water inlet 231 is in communication with a water outlet end of the water replenishing pipe 400, the water outlet 232 is in communication with a drain pipe 110 of the clothes treating apparatus, and a water inlet end of the water replenishing pipe 400 is in communication with a water inlet pipe 340 of the condensing drying system 300.

[0032] It can be understood that the condensing drying system 300 comprises a hot air duct 310, a condenser 330 and a fan heater module 320 arranged in the hot air duct 310, the fan heater module 320 comprises a fan and a heater, the condenser 330 is in communication with the clothes accommodating cavity 170 at an air inlet end thereof, the condenser 330 is in communication with the hot air duct 310 at an air outlet end thereof, the hot air duct 310 is in communication with the clothes accommodating cavity 170 at an air outlet end thereof, the condenser 330 is connected with the water inlet pipe 340 at a water inlet end thereof, and the condenser 330 is in communication with the drain pipe 110 of the clothes treating apparatus at a water outlet end thereof. In addition, in order to realize the above-mentioned water drainage, the drain pump 120 can be arranged on the drain pipe 110.

[0033] During the drying process, the sealing door 200 is closed and the condensing drying system 300 is operated, the condensing drying system 300 sucks in the humid air from the clothes accommodating cavity 170, the humid air is sequentially condensed and heated, and then the heated air is sent into the clothes accommodating cavity 170, the heated air contacts with the clothes in the clothes accommodating cavity 170, the water in the clothes is evaporated, the humid air after contacting with the clothes is sucked in by the condensing drying system 300 again, and the above-mentioned process is repeated. While the condensing drying system 300 is operated, the water replenishing pipe 400 supplies the cooling water into the cooling cavity 230 through the first water inlet 231, the cooling water absorbs and removes the heat on the sealing door 200, and thus the temperature of the sealing door 200 is prevented from being too high. Since the temperature of the sealing door 200 is relatively low, the hot air which is heated by the condensing drying system 300 and then sent into the clothes accommodating cavity 170 contacts with the surface of the sealing door 200 in the machine body 100, and the hot air is condensed on the surface of the sealing door 200, and thus the water content of the hot air in the clothes accommodating cavity 170 is reduced.

[0034] In the above-mentioned embodiment, the temperature of the sealing door 200 during the drying process is relatively low, and thus the user is prevented from being scalded and the environmental temperature is prevented from being too high, and in addition, the drying efficiency is improved, and time is saved and energy is saved.

[0035] As shown in Figures 1-3 some possible embodiments, the sealing door 200 includes an inner shell 220 and a door ring 210 connected with an outer cover, the inner shell 220 is in a basin shape, the inner shell 220 is made of stainless steel, the basin opening of the inner shell 220 is fixedly connected with a side of the door ring 210 away from the outer cover, the door ring 210, the outer cover and the inner shell 220 define a cooling cavity 230, the first water inlet 231 and the water outlet 232 are both arranged on the peripheral wall of the inner shell 220, the door ring 210 is openably installed at the clothes taking and placing opening 130, the inner shell 220 extends into the clothes taking and placing opening 130, and the inner shell 220 is in contact with air in the clothes containing cavity 170. In this way, the heat conduction efficiency between the cooling water in the cooling cavity 170 and the inner shell 220 is high, which is conducive to reducing the temperature of the inner shell 220, and the condensation effect of the inner shell 220 is good. In addition, the stainless steel has good corrosion resistance and long service life.

[0036] Of course, in some examples, the inner shell 220 can also be a transparent basin of an observation window, and the outer cover can be made of transparent material. In this way, it is convenient to observe the inside of the clothes containing cavity 170 through the sealing door 200.

[0037] For example, one side of the door ring 210 can be hinged at a position corresponding to the clothes taking and placing opening 130.

[0038] In some examples, the outer cover is a scald-proof cover. In this way, a second layer of protection is provided to minimize the temperature on the outside of the sealing door 200.

[0039] As shown in Figures 1-3 some examples, such as a drum-type dryer or a washer-dryer, the machine body 100 is provided with an outer drum 150 and an inner drum 160, the inner drum 160 is rotatably installed in the outer drum 150, a plurality of water passing holes are arranged on the inner drum 160, the clothes containing cavity 170 includes an inner cavity 172 located in the inner drum 160 and an outer cavity 171 located between the outer drum 150 and the inner drum 160, the clothes taking and placing opening 130 is in communication with the inner cavity 172 and the outer cavity 171, the clothes to be treated are contained in the inner drum 160, the bottom of the outer cavity 171 has a drain port in communication with the drain pipe 110, and the water outlet 232 is in communication with the outer cavity 171. In this way, during the drying process, the inner drum 160 can drive the clothes to be treated to rotate, which is more sufficient in contact with hot air, and the drying efficiency is higher. In addition, it is also conducive to the discharge of the cooling water in the cooling cavity 230 and the moisture in the clothes.

[0040] In some possible embodiments, the lower edge of the sealing door 200 is outside the inner cavity 172, and the air supply end of the condensing drying system 300 is arranged at the clothes loading / unloading opening 130. For example, in the embodiment in which the sealing door 200 comprises the inner shell 220 and the door ring 210 connected with the outer cover, the lower edge of the inner shell 220 is outside the inner cavity 172. In this way, the condensed water condensed on the surface of the sealing door 200 flows into the drain pipe 110 through the outer cavity 171 between the inner cylinder 160 and the outer cylinder 150, which facilitates the discharge of the condensed water condensed on the surface of the sealing door 200, and meanwhile, can prevent the condensed water from entering the inner cavity 172 to reduce the drying efficiency.

[0041] In some examples, the air inlet end of the condensing drying system is arranged at a side away from the loading / unloading opening, which can improve the utilization efficiency of hot air.

[0042] In some examples, the water outlet end of the condensing drying system is arranged in the outer cavity 171 between the inner cylinder 160 and the outer cylinder 150, and is in communication with the drain pipe 110 through the outer cavity 171. In this way, the water drainage is facilitated, and the drying efficiency of clothes is not affected.

[0043] For example, the air supply end of the hot air duct 310 is arranged above the clothes loading / unloading opening 130, and the air supply end of the hot air duct 310 is directed obliquely downward to supply air to the inner cavity 172 through the clothes loading / unloading opening 130. The condenser 330 is arranged on and opens to the cavity wall of the outer cavity 171, and the air inlet end and the water outlet end of the condenser 330 share one opening, which is in communication with the outer cavity 171.

[0044] In some possible embodiments, the clothes loading / unloading opening 130 is provided with a sealing ring 140 connecting the outer wall of the machine body 100 and the clothes containing cavity 170, the water outlet end of the water replenishing pipe 400 penetrates through the sealing ring 140 and is in communication with the clothes loading / unloading opening 130, and the first water inlet 231 is oppositely arranged with the water outlet end of the water replenishing pipe 400 in the clothes loading / unloading opening 130, so that water can be injected to the first water inlet 231 through the oppositely arranged water outlet end of the water replenishing pipe 400 after the sealing door 200 is closed. In this way, the first water inlet 231 and the water outlet end of the water replenishing pipe 400 do not need to be connected, which facilitates the opening and closing of the sealing door 200.

[0045] For example, the sealing ring 140 is arranged between the outer cylinder 150 and the outer wall of the machine body 100, and the sealing ring 140 connects the outer cylinder 150 and the outer wall of the machine body 100, so that water at the clothes loading / unloading opening 130 can flow into the outer cylinder 150 along the surface of the sealing ring 140.

[0046] In some possible implementations, the outlet of the water supply pipe 400 is located at the top of the clothing loading / unloading port 130 and faces downwards. The first water inlet 231 is located at the top of the cooling chamber 230, below the outlet of the water supply pipe 400. There is a gap between the outlet of the water supply pipe 400 and the first water inlet 231, and the area of ​​the first water inlet 231 is larger than the area of ​​the outlet of the water supply pipe 400. This configuration makes it convenient, efficient, and splash-proof for the outlet of the water supply pipe 400 to fill the first water inlet 231.

[0047] In some examples, the outlet 232 is located at the bottom of the cooling chamber 230 to facilitate drainage of the cooling chamber 230.

[0048] In some possible implementations, the garment processing device also includes a first valve for controlling the opening and closing of the outlet end of the water supply pipe 400 and a second valve for controlling the opening and closing of the outlet 232. This arrangement allows cooling water to be stored in the cooling chamber 230, fully absorbing heat before being discharged, thus improving the utilization efficiency of the cooling water and saving water.

[0049] Furthermore, in existing garment processing equipment, the condenser drying system 300 requires a continuous and large supply of condensate during the drying process, resulting in high water consumption. Simultaneously, the heater operates continuously at over 1.8kW, leading to high energy consumption. In the above embodiment, by utilizing the cooling water stored in the cooling chamber 230 to condense the air, it is unnecessary to continuously supply a large amount of condensate to the condenser drying system 300, thus reducing water consumption. With reduced water consumption, less heat is removed by the condensate in the condenser drying system 300, resulting in greater heat recovery from the air within the system and a higher temperature of the air exiting the system, which is beneficial for drying. When the temperature of the air exiting the condenser drying system 300 remains constant, the energy consumption of the heater can be reduced.

[0050] like Figures 1-3 As shown, in some possible implementations, the first valve is a first buoyancy valve 500 installed in the cooling chamber 230. The first buoyancy valve 500 can use the buoyancy of the cooling water in the cooling chamber 230 to automatically control the opening and closing of the water outlet of the water supply pipe 400 according to the water level change in the cooling chamber 230.

[0051] In some possible implementations, the second valve is a second buoyancy valve 600 installed in the cooling chamber 230. The second buoyancy valve 600 automatically controls the opening and closing of the outlet 232 by utilizing the buoyancy of the cooling water in the cooling chamber 230 and its own weight. This configuration facilitates the automatic control of water replenishment and drainage in the cooling chamber 230.

[0052] Of course, in other embodiments, the first and second valves can also be solenoid valves, pneumatic valves, or other valves, and the first and second valves can also be provided at the laundry loading / unloading opening 130.

[0053] In some possible embodiments, the first buoyancy valve 500 includes a float 510, a rigid rod 520, a first plug 540, and a guide limiting frame 530, the upper end of the rigid rod 520 is fixedly connected with the first plug 540, the lower end of the rigid rod 520 is fixedly connected with the float 510, the first plug 540 is below the water outlet end of the water replenishing pipe 400, the first plug 540 is used to pass through the first water inlet 231 and block the water outlet end of the water replenishing pipe 400, the guide limiting frame 530 is fixedly connected with the cooling cavity 230, the float 510 or the rigid rod 520 is slidingly connected with the guide limiting frame 530, and the float 510 or the rigid rod 520 can move up and down along the guide limiting frame 530. In this way, the water outlet end of the water replenishing pipe 400 can be blocked by using the buoyancy of the cooling water in the cooling cavity 230, when the cooling water in the cooling cavity 230 is insufficient, the first plug 540 is below the water outlet end of the water replenishing pipe 400, the water outlet end of the water replenishing pipe 400 can inject water into the cooling cavity 230 through the first water inlet 231, the guide limiting frame 530 limits the first plug 540 to move only up and down, which is beneficial to the accurate blocking of the water outlet end of the water replenishing pipe 400 by the first plug 540.

[0054] It can be understood that the float 510 is made of a low-density material, the density of which is much smaller than that of the cooling water, and the area of the first plug 540 is larger than that of the water outlet end of the water replenishing pipe 400, after the water level rises and the float 510 drives the first plug 540 to extend out of the first water inlet 231, the first plug 540 can block the water outlet end of the water replenishing pipe 400.

[0055] In some examples, the guide limiting frame 530 can include a connecting frame and a sleeve, the sleeve is vertically arranged and penetrates up and down, the inner cavity of the sleeve is adapted to the rigid rod 520, the rigid rod 520 can slide up and down in the sleeve, the lower end of the rigid rod 520 extends out of the lower end of the sleeve and is fixedly connected with the center of the upper surface of the float 510, the upper end of the rigid rod 520 extends out of the upper end of the sleeve and is fixedly connected with the center of the lower surface of the first plug 540, the area of the upper surface of the float 510 is larger than that of the lower end opening of the sleeve, and the area of the lower surface of the first plug 540 is larger than that of the upper end opening of the sleeve, in this way, the limit positions of the rigid rod 520 moving up and down can be limited, and the rigid rod 520 connected with the first plug 540 and the float 510 can be prevented from moving in a large range in the cooling cavity 230, which affects the observation of the inside of the laundry containing cavity 170 through the transparent sealing door 200.

[0056] In some examples, the first buoyancy valve 500 is made of transparent material, such as acrylic, except for the first plug 540. This makes the user less affected when observing the operation of the laundry containing cavity 170 through the transparent sealing door 200. In particular, during the water filling process, the buoy 510 and the rigid rod 520 made of transparent material are immersed in water, which has negligible effect on the observation effect of the user.

[0057] In some examples, the first plug 540 is a flexible conical plug, which can be a circular truncated cone with the small end upward. In this way, the sealing effect of the water outlet end of the water supply pipe 400 above it is good.

[0058] In some possible embodiments, the water outlet 232 is located below the first water inlet 231, and the second buoyancy valve 600 includes a floating ball 640, a second plug 610, a connecting line 630, and a guide limiting mesh cage 620 arranged in the cooling cavity 230. The floating ball 640 is a flexible ball filled with gas, such as a rubber ball or a silica gel ball. The lower end of the guide limiting mesh cage 620 is fixedly connected to the cooling cavity 230 at the edge of the water outlet 232. The second plug 610 is arranged in the guide limiting mesh cage 620 and directly above the water outlet 232. The second plug 610 is used to block the water outlet 232. The thickness of the second plug 610 is less than the height of the guide limiting mesh cage 620. The second plug 610 can move up and down in the guide limiting mesh cage 620. The floating ball 640 is arranged outside the guide limiting mesh cage 620. One end of the connecting line 630 is connected to the floating ball 640, and the other end of the connecting line 630 is connected to the upper end of the second plug 610 after penetrating into the guide limiting mesh cage 620.

[0059] Thus, when the temperature of the cooling water in the cooling cavity 230 rises, the temperature of the gas in the floating ball 640 rises, the volume of the floating ball 640 increases, and the buoyancy of the floating ball 640 increases. When the temperature of the cooling water in the cooling cavity 230 is low, the volume of the floating ball 640 is small, and the buoyancy of the floating ball 640 is small. The buoyancy of the floating ball 640 and the second plug 610 is less than the weight of the second plug 610 and the water pressure, and the second plug 610 sinks to block the water outlet 232 to store water in the cooling cavity 230. When the cooling water in the cooling cavity 230 reaches the preset temperature, the volume of the floating ball 640 increases. When the buoyancy of the floating ball 640 and the second plug 610 is greater than the sum of the weight of the second plug 610 and the water pressure, the floating ball 640 pulls the second plug 610 up through the connecting line 630. The water outlet 232 is opened, and the cooling water with a higher temperature is discharged through the water outlet 232. The water with a higher temperature in the cooling cavity 230 can be automatically discharged. The guide limiting mesh cage 620 limits the second plug 610 to move up and down only, facilitates accurate blocking of the water outlet 232, and allows the cooling water to enter the guide limiting mesh cage 620. After the second plug 610 is lifted, the cooling water is discharged from the water outlet 232. At the same time, the guide limiting mesh cage 620 can also limit the position of the floating ball 640 to avoid the floating ball 640 moving in a large range and affecting the observation of the inside of the laundry containing cavity 170 through the transparent sealing door 200.

[0060] In some possible embodiments, the first buoyancy valve 500 adopts the structure described above including the float 510, the rigid rod 520, the first plug 540, and the guide limiting frame 530, and the second buoyancy valve 600 adopts the structure described above including the float ball 640, the second plug 610, the connecting wire 630, and the guide limiting cage 620. In this way, before the water injection pipe 400 injects water into the cooling cavity 230, the cooling cavity 230 is waterless, the first plug 540 and the second plug 610 are both at the lower stop position, the water outlet end of the water injection pipe 400 is open, and the second plug 610 blocks the water outlet 232. After the condensing drying system 300 is started, the water injection pipe 400 starts to inject water into the cooling cavity 230, and the water level in the cooling cavity 230 gradually rises until the first plug 540 blocks the water outlet end of the water injection pipe 400, and the water injection pipe 400 stops injecting water into the cooling cavity 230. The cooling water in the cooling cavity 230 absorbs heat on the sealing door 200, and the temperature gradually rises. The temperature of the float ball 640 gradually rises, and the volume gradually increases. When the buoyant force on the float ball 640 and the second plug 610 is greater than the sum of the gravity of the second plug 610 and the water pressure, the float ball 640 pulls the second plug 610 up through the connecting wire 630, the water outlet 232 is opened, the cooling cavity 230 starts to drain water through the water outlet 232, the water level drops, the first plug 540 synchronously drops, and the water injection pipe 400 starts to inject cooling water into the cooling cavity 230 again. The original cooling water with a higher temperature in the cooling cavity 230 is gradually drained, the newly injected cooling water gradually lowers the temperature in the cooling cavity 230, the temperature of the float ball 640 gradually lowers, and the volume gradually decreases. When the buoyant force on the float ball 640 and the second plug 610 is less than the gravity of the second plug 610 and the water pressure, the second plug 610 sinks to block the water outlet 232, the cooling cavity 230 stops draining water, and the water injection pipe 400 continues to inject water into the cooling cavity 230 until the first plug 540 blocks the water outlet end of the water injection pipe 400. In this way, the cooling water is automatically injected and drained, which is beneficial to keeping the temperature of the cooling water in the cooling cavity 230 from being too high.

[0061] In some possible embodiments, the second plug 610 includes a rigid body in the middle and an elastic layer wrapped outside the rigid body. The rigid body can be made of a metal material, and the elastic layer can be a rubber layer. In this way, the blocking effect is good when the water outlet 232 is blocked.

[0062] Referring to Figure 4 , Figure 4 is a schematic view of a water distributor of an embodiment of the laundry treatment apparatus. As Figure 4As shown, in some possible implementation, the clothes treatment apparatus further comprises a water distributor 700, a water storage cavity 710 is formed in the water distributor 700, a second water inlet 720 is arranged at the upper portion of the water storage cavity 710, the second water inlet 720 is used to communicate with a water supply device, a water distribution port 730 is arranged on the sidewall of the water storage cavity 710, the water distribution port 730 communicates with the water inlet end of the water supply pipe 400, the water inlet end of the water inlet pipe 340 of the condensing drying system 300 extends into the water storage cavity 710, the water inlet end of the water inlet pipe 340 of the condensing drying system 300 communicates with the water storage cavity 710, the water inlet end of the water inlet pipe 340 of the condensing drying system 300 is above the water distribution port 730, and the area of the second water inlet 720 is smaller than the area of the water inlet end of the water inlet pipe 340 of the condensing drying system 300.

[0063] In this way, the water supplied through the second water inlet 720 is first depressurized in the water storage cavity 710, and then supplied into the water supply pipe 400 and the water inlet pipe 340 of the condensing drying system 300, respectively, so as to avoid that the water supplied is too large in pressure when the water supply pipe 400 is directly connected with a water pipe. When the water level in the water storage cavity 710 reaches the water inlet end of the water inlet pipe 340 of the condensing drying system 300, the water in the water storage cavity 710 flows into the water inlet end of the water inlet pipe 340 of the condensing drying system 300, the water level in the water storage cavity 710 can be limited by the water inlet end of the water inlet pipe 340 of the condensing drying system 300, and thus the pressure of the water entering the water supply pipe 400 can be limited. When the first valve is the first float valve 500, the first float valve 500 cannot be blocked at the water outlet end of the water supply pipe 400 due to the buoyancy, and meanwhile, the size of the float 510 and the first plug 540 can be reduced. In addition, the area of the second water inlet 720 is smaller than the area of the water inlet end of the water inlet pipe 340 of the condensing drying system 300, so as to ensure that the excess water can all flow into the water inlet pipe 340 of the condensing drying system 300.

[0064] It can be understood that a third valve 800 can be arranged at the second water inlet 720, and the third valve 800 can be an electromagnetic valve or a pneumatic valve.

[0065] In some possible implementation, the water inlet end of the water inlet pipe 340 of the condensing drying system 300 faces upward, the downward projection of the second water inlet 720 includes a first region within the range of the water inlet end of the water inlet pipe 340 of the condensing drying system 300 and a second region outside the range of the water inlet end of the water inlet pipe 340 of the condensing drying system 300, and the area of the first region is greater than the area of the second region.

[0066] In this way, the water flowing in through the second water inlet 720 mostly enters the water inlet pipe 340 of the condensing drying system 300, and a small amount is stored in the water storage cavity 710 and flows into the water supplement pipe 400 through the water storage cavity 710. When the pressure of the water supplied from the second water inlet 720 is particularly high and the pressure relief capacity of the water storage cavity 710 alone is insufficient, pressure relief can be performed through the water inlet end of the water inlet pipe 340 of the condensing drying system 300, the pressure relief effect is good, and the water pressure flowing into the water supplement pipe 400 can be ensured to be not greater than the pressure generated by the water level at the water inlet end of the water inlet pipe 340 of the condensing drying system 300.

[0067] If water is stored in the cooling cavity 230 at ordinary times, the sealing door 200 hinge may bear a large gravity, causing the sealing door 200 to sag, and also affecting the user's experience of opening and closing the door. Therefore, when the drying is about to end, the third valve 800 can be closed in advance to stop supplying water to the water supplement pipe 400 and the water inlet pipe 340 of the condensing drying system 300, so that condensation only occurs on the surface of the sealing door 200, until the float 510 is monitored to descend, indicating that at this time the water has been drained and the water supplement has been interrupted.

[0068] There are many specific methods for monitoring the descent of the float 510, and only the following examples are given here. A magnet is installed on the float 510, and a reed tube is installed at the corresponding position of the sealing door 200. When the drying is about to end, the circuit in which the reed tube is located is powered on, and then whether the circuit is connected is monitored. If connected, it means that the float 510 has descended to that position.

[0069] The specific time for closing the third valve 800 in advance can be determined by experiment and fixed in the drying program.

[0070] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to related technical features without departing from the principles of the present application, and the technical solutions after these changes or replacements will all fall within the protection scope of the present application.
