[0027] As Figures 1 to 7 shown, the present invention relates to a refrigeration appliance, which includes an inner container 100, a box body 200, an evaporator 300 and a humidifying member 400. The evaporator 300 is used to generate refrigerated air and release it into the indoor space where the refrigeration appliance is located through the box body 200 to achieve refrigeration. The humidifying member 400 is used to collect the defrosting water and / or condensate water in the inner container 100, atomize the defrosting water and / or condensate water, and then release it into the indoor space where the refrigeration appliance is located through the box body 200 to achieve humidification. Here, a refrigerator is taken as an example.

[0028] Among them, the inner container 100 forms a refrigeration compartment, and a through hole is formed at the bottom of the rear side of the inner container 100 to discharge the defrosting water. In this embodiment, three groups of the inner containers 100 are arranged along the height direction, respectively forming a refrigerating compartment, a variable-temperature compartment and a freezing compartment.

[0029] Box body 200, the box body 200 has an independent refrigeration area 201 and a humidification area 202 inside. The refrigeration area 201 and the humidification area 202 are respectively communicated with the external space of the refrigeration appliance, and the evaporator 300 is located in the refrigeration area 201, and the humidifying member 400 is located in the humidification area 202. In this embodiment, the box body 200 is located between the inner containers 100.

[0030] The air in the refrigeration area 201 flows through the evaporator 300, exchanges heat with the evaporator 300 and then cools down, and then is discharged to the indoor space where the refrigeration appliance is located through the refrigeration area 201; the humidifying member 400 works to generate atomized water vapor, and then is discharged to the indoor space where the refrigeration appliance is located through the humidifying area 202.

[0031] Further, the refrigeration area 201 includes a diversion area 201a and an air outlet area 201b communicating the diversion area 201a with the external space of the refrigeration appliance, and the evaporator 300 is located in the diversion area 201a. Air enters from one end of the diversion area 201a away from the air outlet area 201b and flows to the position where the evaporator 300 is located, exchanges heat with the evaporator 300 and cools down, then diffuses into the air outlet area 201b, and finally flows to the indoor space where the refrigeration appliance is located to achieve refrigeration.

[0032] The refrigeration area 201a is successively an expansion section, a refrigeration section and a diversion section from the end away from the air outlet area 201b to the air outlet area 201b. The evaporator 300 is located in the refrigeration section, that is, the evaporator 300 is located at the middle position of the refrigeration area 201a. The air outlet area 201b is in a horn shape, and the opening of the air outlet area 201b gradually increases from the connection end with the refrigeration area 201a to the front of the refrigeration appliance, so as to facilitate the diffusion of cold air.

[0033] Specifically, the expansion section gradually expands from the end away from the air outlet area 201b to the refrigeration section, that is, the width of the expansion section gradually increases. In this way, the wind speed flowing from the expansion section to the refrigeration section can be effectively reduced, so that the air can fully exchange heat with the evaporator 300 to reduce the temperature. The refrigeration area 201a further includes a diversion structure located in the expansion section. The diversion structure is in a streamline shape, so that the air flowing from the expansion section to the refrigeration section circulates more smoothly and the wind loss is smaller. In this embodiment, the diversion structure is an arc-shaped diversion structure protruding upward from the bottom of the expansion section.

[0034] A water guiding hole is formed at the bottom of the refrigeration section, and a water guiding member 205 is connected to the water guiding hole. The defrosting water of the evaporator 300 is guided to the water guiding member 205 through the water guiding hole at the bottom of the refrigeration section, and finally discharged through the water guiding member 205.

[0035] The diversion section extends obliquely from the refrigeration section towards the air outlet area 201b, facilitating the inflow of the cooled air after heat exchange into the air outlet area 201b through the diversion section. A water-stop structure is provided inside the diversion section to prevent the defrosting water of the evaporator 300 from flowing into the diversion section. In this embodiment, the water-stop structure protrudes upward from the bottom of the diversion section and has a triangular cross-section. The side of the water-stop structure facing the refrigeration section is an inclined surface, enabling the cooled air after heat exchange to rise along the inclined surface and preventing the cooled air from sinking and being accumulated in the refrigeration section by the water-stop structure, which may lead to a reduction in refrigeration efficiency.

[0036] Further, a first diversion fan 203 is provided inside the box body 200 at the connection position between the diversion area 201a and the air outlet area 201b, and a second diversion fan 204 is provided inside the diversion area 201a. The second diversion fan 204 is arranged facing the first diversion fan 203.

[0037] Specifically, the second diversion fan 204 is located inside the diversion section. The second diversion fan 204 is used to blow the cooled air in the refrigeration area 201a towards the air outlet area 201b, and the first diversion fan 203 is used to blow the cooled air in the air outlet area 201b to the external space of the refrigeration appliance. There are two groups of the first diversion fans 203 arranged side by side to accelerate the discharge of the cooled air. The angles of the first diversion fan 203 and the second diversion fan 204 can be adjusted, automatically adjusted according to the required wind speed, temperature, and air volume to meet the different cooling requirements of the environment.

[0038] A refrigeration system includes a first evaporator (not shown in the figure) for cooling the refrigeration compartment of the refrigeration appliance and a second evaporator 300 connected in parallel with the first evaporator. The second evaporator 300 is located inside the refrigeration air duct 200. The first evaporator is used to cool the internal space of the refrigeration appliance, and the second evaporator 300 is used to cool the external space where the refrigeration appliance is located.

[0039] Further, the humidifying member 400 includes a first outlet 401 communicating with the refrigeration area 201, a second outlet 402 communicating with the humidification area 202, and a water inlet 403 away from the first outlet 401 and the second outlet 402.

[0040] The second outlet 402 is located at the position of the humidifying member 400 facing the front side of the refrigeration appliance. The humidification area 202 extends from the second outlet 402 towards the front side of the refrigeration appliance. The first outlet 401 is located on the side of the humidifying member 400. The air outlet area 201b is parallel to the humidification area 202, and the diversion area 201a extends from the second outlet 402 towards the air outlet area 201b.

[0041] Furthermore, a refrigeration fan is provided at the first outlet 401, and a baffle is movably provided at the second outlet 402. The baffle moves in the height direction to open or close the second outlet 402. When humidification is required, the refrigeration fan and the evaporator 300 are kept closed, and the humidifying member 400 operates to generate atomized water vapor, which flows into the humidifying area 202 from the second outlet 402 and finally into the indoor space where the refrigeration appliance is located to achieve humidification; when refrigeration is required, the second outlet 402 is closed by the baffle, the humidifying member 400 does not operate, the refrigeration fan and the evaporator 300 are turned on, so as to guide air to the diversion area 201a and exchange heat with the evaporator 300 to cool down, and under the action of the first diversion fan 203 and the second diversion fan 204, it is discharged to the indoor space where the refrigeration appliance is located through the air outlet area 201b to achieve refrigeration.

[0042] The humidifying member 400 further includes a water supply pipe 404 connecting the inner container 100 and the humidifying member 400, a water supply pump 405, and a filter member located on the water supply pipe 404.

[0043] The humidifying member 400 can adopt an atomizing humidifier. One end of the water supply pipe 404 is connected to a through hole at the bottom rear side of the inner container 100, and the other end is connected to the water inlet 403 of the humidifying member 400 through the water supply pump 405, so as to divert the defrosting water in the inner container 100 into the humidifying member 400 for atomizing humidification. The filter member is used to filter and purify the defrosting water to remove bacteria and impurities in the defrosting water for subsequent atomizing humidification by the humidifying member 400.

[0044] Furthermore, the water supply pipe 404 includes a U-shaped pipe section connected to the bottom of the inner container 100 and a diversion pipe section connecting the U-shaped pipe section and the humidifying member 400. The defrosting water in the inner container 100 flows into the humidifying member 400 through the U-shaped pipe section and the diversion pipe section, and the filter member is located in the diversion pipe section.

[0045] The U-shaped pipe section can be used as a temporary water storage area for storing water. The U-shaped pipe section first extends downward from the through hole at the bottom of the inner container 100, then extends horizontally away from the inner container 100, and finally extends upward and is connected to the diversion pipe section. In this way, a certain volume of defrosting water can be stored in the U-shaped pipe section. Preferably, the pipe diameter of the U-shaped pipe section is larger than that of the diversion pipe section, so as to increase the water storage capacity of the U-shaped pipe section, and at the same time, the small-diameter diversion pipe section is convenient for sucking the defrosting water in the U-shaped pipe section into the humidifying member 400.

[0046] The water supply pipe 404 further includes a liquid level sensor located within the U-shaped pipe section, and the height at which the liquid level sensor is located is lower than the height of the connection between the U-shaped pipe section and the inner container 100.

[0047] The liquid level height within the U-shaped pipe section is monitored by the liquid level sensor to prevent the defrosting water within the U-shaped pipe section from being discharged in a timely manner, and the water level height being greater than the height of the through hole at the bottom of the inner container 100 resulting in the defrosting water within the inner container 100 being unable to be discharged. When the water level height within the U-shaped pipe section reaches the position where the liquid level sensor is located, the water supply pump 405 is immediately activated to divert the defrosting water within the U-shaped pipe section to the humidifying member 400 for humidification.

[0048] Furthermore, the refrigeration appliance further includes a cleaning pipe 500 located within the air duct of the refrigeration appliance, a recovery box 600 located at the rear side of the box body 200, and a water storage box 700 located within the inner container 100. The water storage box 700 is used to store the cleaning liquid and is connected to the cleaning pipe 500, and the cleaning liquid sprayed into the air duct 200 flows back along the air duct and is collected into the recovery box 600.

[0049] Specifically, the cleaning pipe 500 is located within the air duct at the rear side of the refrigerating compartment, the box body 200 is located between the refrigerating compartment and the variable temperature compartment, the water storage box 700 is located within the refrigerating compartment, and the water supply pipe 404 is connected and arranged in two groups. One group is connected to the variable temperature compartment and the humidifying member 400, and the other group is connected to the freezing compartment and the previous group of the water supply pipe 404. By placing the water storage box 700 storing the cleaning liquid within the refrigerating compartment, it facilitates the installation of the water storage box 700 and the subsequent addition of the cleaning liquid; at the same time, the water storage box 700 located within the refrigerating compartment can effectively reduce the temperature of the cleaning liquid, preventing the loss of cold air within the air duct during the cleaning of the air duct and additionally increasing the energy consumption of the refrigeration appliance. In this embodiment, the diversion pipe section of the water supply pipe 404 connected to the freezing compartment is connected to the U-shaped pipe section of the water supply pipe 404 connected to the variable temperature compartment.

[0050] In other embodiments, the cleaning pipe 500 can be provided within the air duct of each compartment to achieve the cleaning of all air ducts, and the water supply pipe 404 and the water storage box 700 can be selectively enabled.

[0051] The evaporator within the refrigeration appliance generates refrigerated air after heat exchange, and the refrigerated air enters the refrigerating compartment through the air duct. The air duct is formed by an air duct plate and an air duct cover plate. When dirt such as dust and bacteria accumulates within the air duct, it is likely to cause a decline in the refrigeration effect of the refrigeration appliance and the generation of peculiar smells within the refrigerating compartment. At this time, the cleaning liquid stored within the water storage box 700 can be injected into the cleaning pipe 500 and sprayed into the air duct through the cleaning pipe 500 to achieve the cleaning of the air duct.

[0052] The air duct includes a main air duct located in the middle of the air duct plate, and a plurality of shunt air ducts located on both sides of the main air duct and communicating with the main air duct. The main air duct extends in the height direction, the shunt air ducts are arranged at intervals in the height direction, and the shunt air ducts are used to evenly shunt the refrigerating air in the main air duct and introduce it into the refrigerator compartment. The side of the shunt air duct away from the main air duct is the air outlet communicating with the refrigerator compartment.

[0053] The shunt air duct is divided into an air inlet section connected to the main air duct and an air outlet section connecting the air inlet section and the air outlet. The air inlet section has a certain inclination angle to facilitate the shunting of the refrigerating air into it, and the air outlet section is relatively gentle to facilitate the smooth export of the refrigerating air.

[0054] A water outlet is provided at the lowest point of the air duct, and a recovery pipe extending to the top of the recovery box 600 is connected to the water outlet. The cleaning liquid gradually gathers along the air duct to the water outlet at the lowest point, and then is collected into the recovery box 600 through the recovery pipe. Of course, the defrosting water in the refrigerating compartment can also be diverted to the recovery box 600 through the recovery pipe.

[0055] The air duct further includes a drainage groove opened along its lower edge. The drainage groove extends along the lower edge of the air duct to the drainage port, and the drainage groove is used to divert the cleaning liquid sprayed out from the cleaning pipeline. When the air duct needs to be cleaned, the cleaning liquid is introduced into the cleaning pipe 500, and the cleaning liquid is sprayed into the air duct through the cleaning pipe 500 to clean the air duct. The cleaning liquid flows down along the inner wall of the air duct to the drainage groove at the lower edge of the air duct, and finally gathers along the drainage groove to the drainage port at the lowest point of the air duct and is discharged.

[0056] The depth of the drainage groove is 0.5 - 1 cm, and the depth of the drainage groove can be determined according to the area of the air duct and the flow value of the cleaning pipe 500. By opening the drainage groove, the cleaning liquid can be effectively prevented from remaining in the air duct.

[0057] A water mist sensor is also arranged in the air duct, and the water mist sensor is used to detect the remaining situation of the cleaning liquid in the air duct. The water mist sensor is arranged at a position in the air duct where the cleaning liquid is likely to remain.

[0058] Specifically, the water mist sensor is located at the position with the smallest inclination angle of the air duct. In this embodiment, the water mist sensor is located at the lower edge of the connection between the air inlet section and the air outlet section, and the inclination angle at this position is small and the cleaning liquid is likely to remain. The water mist sensors are also arranged on both sides of the drainage port, and the water mist sensors at this place can detect the discharge situation of the cleaning liquid to prevent the drainage port from being blocked and unable to discharge the cleaning liquid in time.

[0059] The cleaning pipe 500 extends in a tree-like shape along the air duct and is consistent with the shape of the air duct, so as to spray the cleaning liquid to various positions of the air duct. Spray nozzles are arranged at intervals on the cleaning pipe 500, and the cleaning liquid in the cleaning pipe 500 is evenly sprayed into the air duct through the spray nozzles, so as to realize the overall cleaning of the air duct and prevent dust and bacteria from gathering in the air duct.

[0060] Further, a groove is provided in the air duct, and the cleaning pipe 500 is embedded in the groove to achieve fixation. At least part of the cleaning pipe 500 is embedded in the groove, and the opening depth of the groove can be adjusted adaptively according to needs.

[0061] The groove can be opened along the middle position or the edge position of the air duct. When the groove is opened along the middle position of the air duct, the cleaning pipe 500 is fixed at the middle position of the air duct, and the spray nozzles can spray the cleaning liquid evenly around, so that the cleaning pipe 500 has the largest spraying range and the highest cleaning efficiency; when the groove is opened along the edge of the air duct, the cleaning pipe 500 is fixed at the edge position of the air duct, and the spray nozzles spray in a fan shape upward or downward, which can reduce the influence of the cleaning pipe 500 on the air supply of the air duct. In this embodiment, it is preferably to open the groove on the upper edge of the air duct 200, which can reduce the obstruction of the cleaning pipe 500 to the backflow of the cleaning liquid, improve the backflow efficiency of the cleaning liquid, and prevent the cleaning liquid from remaining in the air duct.

[0062] Of course, in other embodiments, the cleaning pipe 500 can also be fixed by other means, such as fixing the cleaning pipe 500 through the spray nozzles. The spray nozzles are arranged at intervals along the air duct and are fixed in the air duct by means of inlaying, adsorption, etc., and the cleaning pipe 500 is fixed with the spray nozzles as the positioning points. The spray nozzles can support the cleaning pipe 500 away from the inner wall of the air duct to a certain extent, so as to prevent the cleaning liquid from remaining.

[0063] Further, multiple groups of liquid spraying ports are arranged circumferentially on the spray nozzle to increase the spraying range of the spray nozzle. An inlet is arranged in the center of the spray nozzle to connect the cleaning pipe 500 and the liquid spraying ports. The cleaning liquid in the cleaning pipe 500 flows into the spray nozzle through the inlet, and then is sprayed out through the liquid spraying ports to clean the air duct. A pressure valve is arranged at the inlet. When the water pressure value at the inlet is less than the set value, the pressure valve closes the inlet; when the water pressure value at the inlet is greater than the set pressure value, the pressure valve is pushed up, and the cleaning liquid flows into the spray nozzle and is sprayed out from the liquid spraying ports, so as to ensure that the spray nozzle has a certain spraying range and a certain water pressure value to improve the cleaning efficiency of the air duct.

[0064] The defrost water in the variable temperature compartment is stored in the U-shaped pipe section of the water supply pipe 404 connected thereto, and the defrost water in the freezing compartment is stored in the U-shaped pipe section of the water supply pipe 404 connected thereto. When the storage height of the defrost water in any one of the U-shaped pipe sections reaches the height where the liquid level sensor is located, the water supply pump 405 is turned on to suck the defrost water in the two U-shaped pipe sections into the humidifying member 400 through the diversion pipe section for humidification.

[0065] Further, a filter element is provided in the recovery box 600, and the recovery box 600 is respectively communicated with the humidifying member 400 and the water storage box 700.

[0066] The recovery pipe is connected to the top of the recovery box 600. The cleaning liquid sprayed into the air duct flows into the top of the recovery box 600 along the recovery pipe, and then is filtered and purified by the filter element and penetrates to the bottom of the recovery box 600. The recovery box 600 is connected to the humidifying member 400 through the water supply pump 405. The water supply pump 405 has two inlets and one outlet. The two outlets are respectively connected to the recovery box 600 and the water supply pipe 404, and the outlet is connected to the humidifying member 400, so as to provide humidifying water for the humidifying member 400.

[0067] In this embodiment, the water guiding member 205 is a water guiding plate connecting the recovery box 600 and the water guiding hole to guide the defrost water of the evaporator 300 into the recovery box 600, and a filtering member is provided at the connection between the recovery box 600 and the water guiding member 205.

[0068] The water storage box 700 is provided with an independent cleaning water chamber and a cleaning agent chamber. The cleaning water chamber is used to hold cleaning water, and the cleaning agent chamber is used to hold cleaning agent. The cleaning water and the cleaning agent are mixed to form a cleaning liquid. A connecting pipe is connected to the water storage box 700. The connecting pipe includes a first liquid inlet end communicated with the cleaning water chamber, a second liquid inlet end communicated with the cleaning agent chamber, and an outlet end connected to the cleaning pipeline 300. A cleaning pump is provided on the connecting pipe. The cleaning water and the cleaning agent in the water storage box 700 are connected to the cleaning pipe 500 located in the air duct through the cleaning pump, and the cleaning pipe 500 sprays the cleaning liquid into the air duct, so as to complete the cleaning of the air duct.

[0069] Further, the connecting pipe includes a main connecting pipe connected to the cleaning pipe 500, a first branch pipe communicating with the main connecting pipe and extending into the cleaning water chamber, and a second branch pipe communicating with the first branch pipe and extending into the cleaning agent chamber. The cleaning liquid formed by mixing the cleaning water and the cleaning agent is sprayed into the air duct. The cleaning pump is located on the main connecting pipe. The inner diameters of the first branch pipe and the second branch pipe can be set according to the mixing ratio of the cleaning water and the cleaning agent. In this way, the proportional mixing of the cleaning water and the cleaning agent can be achieved by the cleaning pump located on the main connecting pipe.

[0070] A communication valve is further provided on the second branch pipe, which can supply the mixed cleaning liquid or supply cleaning water alone to the cleaning pipeline 300.

[0071] By placing the water storage box 700 storing the cleaning liquid in the cold storage room, it is convenient for the installation of the water storage box 700 and the subsequent addition of the cleaning liquid. At the same time, the water storage box 700 located in the cold storage room can effectively reduce the temperature of the cleaning liquid, prevent the loss of cold in the air duct when cleaning the air duct, and additionally increase the energy consumption of the refrigerator.

[0072] The recovery box 600 is also communicated with the water storage box 700. The refrigeration appliance has active humidification and passive humidification. When the storage height of the defrosting water in the U-shaped pipe section reaches the height where the liquid level sensor is located or the cleaning liquid stored in the recovery box 600 reaches a certain amount, the humidifying member 400 starts passive humidification. When the indoor environment is relatively dry, active humidification is turned on. At this time, the humidification demand is large, and the cleaning liquid in the water storage box 700 can be introduced into the recovery box 600 to provide humidifying water for the humidifying member 400.

[0073] In summary, the present invention adds the box body 200 between the inner linings 100, and arranges the evaporator 300 and the humidifying member 400 in the box body 200, and uses the cold in the refrigeration appliance and the defrosting water to cool or humidify the indoor space where the refrigeration appliance is located, so that the refrigeration appliance has the functions of both an air conditioner and a humidifier.
