Abstract

The present invention discloses a wine cabinet and a humidity control method thereof. The wine cabinet comprises an inner tank, which defines a refrigerating chamber, an air duct, which extends from top to bottom along the rear wall of the inner tank; an evaporator, which is arranged in the air duct; a water receiving box, which is located in the air duct and arranged at the lower side of the evaporator; a fan, which is located in the air duct and arranged at the upper side of the evaporator; the fan makes the circulating air of the air duct pass through the evaporator and then partially discharge into the refrigerating chamber, and partially discharge into the refrigerating chamber after passing through the water receiving box. The wine cabinet can realize the control of humidity in the wine cabinet by adding a water receiving box and actively humidifying.

Since the fan and the water receiving box are located at the upper and lower ends of the evaporator, after the fan is turned on, the circulating air will all blow to the evaporator, and finally blow out from the bottom water receiving box, thereby ensuring the maximum air volume passing through the evaporator, minimizing the drop speed of humidity, and preventing the humidity in the wine cabinet from dropping suddenly.

Description

Technical Field

[0001] The present invention relates to the technical field of wine cabinets, and in particular to a humidity control method for a wine cabinet. Background Art

[0002] Traditional wine cabinets bring many problems to users because the humidity inside the cabinet is not controlled. When the humidity inside the cabinet is too low, the corks of the wine bottles are exposed to the low humidity environment for a long time, and the corks are easy to crack. When air enters the wine bottles, the stored wine will oxidize and deteriorate. When the humidity inside the cabinet is too high, the corks and wine labels are exposed to the high humidity environment for a long time. The corks will be moldy and the wine will be damaged. The wine labels will be blurred or cracked, causing inconvenience to users. Summary of the invention

[0003] Based on this, the technical problem to be solved by the present invention is to provide a wine cabinet and a humidity control method thereof which can adjust the humidity in the wine cabinet and prevent a sudden drop in humidity when the wine cabinet is refrigerated.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0005] A wine cabinet includes an inner tank, wherein a refrigerating chamber is defined.

[0006] An air duct extending from top to bottom along the rear wall of the inner liner in the inner liner;

[0007] an evaporator, disposed in the air duct;

[0008] A water receiving box is located in the air duct and is arranged at the lower side of the evaporator;

[0009] The fan is located in the air duct and is arranged on the upper side of the evaporator; the fan allows the circulating air in the air duct to be partially discharged into the refrigerating chamber after passing through the evaporator, and partially discharged into the refrigerating chamber after passing through the water receiving box.

[0010] Furthermore, the evaporator is arranged at a middle position of the air duct in the front-to-back direction, and the circulating air of the air duct can flow through the front side and the rear side of the evaporator.

[0011] Furthermore, the water receiving box is integrally formed with the inner tank and is a groove arranged at the bottom of the inner tank.

[0012] Furthermore, it also includes a humidity detection device for detecting the current internal humidity of the wine cabinet.

[0013] Furthermore, the humidity detection device is a humidity sensor, which is arranged close to the return air outlet of the fan.

[0014] The present invention also includes a wine cabinet humidity control method, including the wine cabinet described above, the control method comprising:

[0015] Get the current internal temperature and humidity of the wine cabinet;

[0016] Determine whether the internal temperature is within a preset temperature range. When the internal temperature is higher than the preset temperature range, control the fan to start. After the fan is running, control the compressor to start and run the refrigeration.

[0017] When the internal temperature is lower than the preset temperature, the compressor is controlled to be turned off to stop refrigeration.

[0018] Furthermore, after the step of controlling the compressor to turn off and stop refrigeration when the internal temperature is lower than the preset temperature, the method further includes:

[0019] The fan is controlled to continue running, and it is determined whether the internal humidity is within a preset humidity range. When the internal humidity is higher than the preset humidity range, the fan is controlled to be turned off.

[0020] Furthermore, the fan is a variable speed fan. When judging whether the internal temperature is within a preset temperature range, if the internal temperature is higher than the preset temperature range, the fan is controlled to turn on. After the fan is running, the compressor is controlled to start. In the step of running the cooling mode, the fan is controlled to run at the maximum speed.

[0021] Furthermore, the fan is a variable speed fan; when controlling the fan to continue running, it is determined whether the internal humidity is within a preset humidity range. When the internal humidity is higher than the preset humidity range, the fan is controlled to shut down, and the fan is controlled to run at a maximum speed.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are:

[0023] The wine cabinet described above, by adding a water receiving box, uses a fan to drive the circulating air to blow water, and actively humidifies to achieve control of the humidity in the wine cabinet. In order to slow down the instantaneous drop in humidity, the fan can be turned on first, and then the compressor can be turned on for cooling. Since the fan and the water receiving box are located at the upper and lower ends of the evaporator, after the fan is turned on, the circulating air will all blow to the evaporator, and finally blow out from the bottom water receiving box, ensuring the maximum air volume passing through the evaporator, minimizing the drop in humidity, and preventing a sudden drop in humidity in the wine cabinet.

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] Reference Figure 1-Figure 3, which is an embodiment of the wine cabinet of the present invention. The wine cabinet includes a box body 100, in which an inner tank 110 with an open front is arranged, and the inner tank 110 defines a refrigeration chamber for storing things. The air duct 130 is arranged in the inner tank 110 along the rear wall of the inner tank 110 from top to bottom, and the air duct 130 is formed between the air duct cover 120 and the rear wall of the inner tank 110. The refrigeration system of the wine cabinet includes a compressor, an evaporator 200, a condenser, a throttling element, etc. Among them, the evaporator 200 is arranged in the air duct 130, and the evaporator 200 is preferably a blowing evaporator 200. The water collecting box 400 is located in the air duct 130, and is arranged at the lower side of the evaporator 200, and is used to collect condensed water of the evaporator 200. The fan 300 is located in the air duct 130 and is arranged on the upper side of the evaporator 200; the fan 300 allows the circulating air in the air duct 130 to pass through the evaporator 200, and then part of it is discharged into the refrigerated room, and part of it flows through the water receiving box 400 and then flows into the refrigerated room. In this embodiment, the upper part of the air duct cover plate 120 is provided with a return air port 122, and the fan 300 is arranged in the air duct 130 at the return air port 122, and the middle and lower parts of the air duct cover plate 120 are provided with air outlets 121. Part of the circulating air that flows through the evaporator 200 is discharged from the middle air outlet 121 to achieve refrigeration in the refrigerated room, and the other part flows through the water receiving box 400 at the bottom, sweeps the water surface of the water receiving box 400, and is blown out into the refrigerated room through the lower air outlet 121 to achieve humidification in the refrigerated room.

[0038] When the refrigeration system of the wine cabinet is working, the temperature of the evaporator 200 and the surrounding pressure must be lower than the temperature and pressure in the refrigerator. The humid air in the refrigerator will condense into water in the evaporator 200 as it circulates with the wind. Therefore, the working process of the refrigeration system is a process of cooling and dehumidification. By adding a water receiving box 400, the circulating wind is driven by the fan 300 to blow water, and active humidification is achieved to control the humidity in the wine cabinet. In order to slow down the instantaneous drop in humidity, the fan 300 can be turned on first, and then the compressor can be turned on for cooling. Since the fan 300 and the water receiving box 400 are located at the upper and lower ends of the evaporator 200, after the fan 300 is turned on, the circulating wind will all blow to the evaporator 200, and finally blow out from the bottom water receiving box 400, ensuring the maximum air volume passing through the evaporator 200, minimizing the drop in humidity, and preventing a sudden drop in humidity in the wine cabinet.

[0039] A temperature detection device is provided in the wine cabinet. The temperature detection device includes a temperature sensor. The temperature detection device can detect the internal temperature of the wine cabinet in real time. The temperature detection device is connected to the control system. The control system controls the opening and closing of the refrigeration system through the detected internal temperature.

[0040] Furthermore, the wine cabinet further includes a humidity detection device for detecting the current internal humidity of the wine cabinet. The humidity detection device is connected to the control system of the wine cabinet, and the control system can control the opening and closing of the fan 300 by detecting the internal humidity. The humidity detection device includes a humidity sensor. The temperature sensor and the humidity sensor are preferably arranged near the return air port 122 of the fan 300. By arranging the humidity detection device to detect the humidity in the wine cabinet in real time, the humidity adjustment is achieved by controlling the operation of the fan 300.

[0041] Preferably, the evaporator 200 is arranged at the middle position of the air duct 130 in the front-to-back direction, and the air in the air duct 130 can flow through the front and rear sides of the evaporator 200. The wind passing through the front side of the evaporator 200 sweeps the front side of the evaporator 200 and passes through the middle air outlet 121 to achieve refrigeration in the box; the wind passing through the rear side of the evaporator 200 sweeps the rear side of the evaporator 200 and passes through the middle air outlet 121 to achieve refrigeration in the box, and at the same time, humidification in the box is achieved by sweeping the water surface at the bottom of the liner 110. The circulating wind in the air duct 130 can flow through the front and rear sides of the evaporator 200. After the refrigeration system of the wine cabinet stops working, when the fan 300 works to humidify, the circulating wind blows to the front and rear sides of the evaporator 200 at the same time, which can accelerate the defrosting and evaporation of the condensed water of the evaporator 200 and improve the humidification speed and efficiency.

[0042] In this embodiment, the water receiving box 400 is integrally formed with the inner liner 110 and is a groove disposed at the bottom of the inner liner 110. The structure is simple and the cost is low. In other embodiments, the water receiving box 400 can also be an independent component fixed to the bottom of the inner liner 110.

[0043] like Figure 4 As shown, the humidity control method of the wine cabinet of the present invention specifically includes the following steps:

[0044] S100, obtaining the current internal temperature and internal humidity of the wine cabinet.

[0045] S200, determining whether the internal temperature is within a preset temperature range. When the internal temperature is higher than the preset temperature range, the fan is controlled to start. After the fan is running, the compressor is controlled to start for cooling.

[0046] S300: When the internal temperature is lower than the preset temperature, the compressor is controlled to shut down and refrigeration is stopped.

[0047] In step S100 , the internal temperature and the internal humidity are acquired by a temperature sensor and a humidity sensor.

[0048] In the above-mentioned wine cabinet humidity control method, when the temperature inside the wine cabinet is high, higher than the preset temperature range, the fan is turned on first, and then the compressor is started for cooling. Because the fan is turned on first to blow through the evaporator, after the compressor starts cooling, the evaporator frosting speed will be reduced, which can slow down the instantaneous drop in humidity. The humidity is finally maintained above 50% before the compressor stops. At the same time, since the fan and the water collection box are located at the upper and lower ends of the evaporator, after the fan is turned on, the circulating air will all blow to the evaporator, and finally blow out from the bottom water collection box, ensuring the maximum air volume passing through the evaporator and minimizing the rate of humidity drop. Based on the structural design of the wine cabinet, under the control of this control method, constant control of the humidity in the wine cabinet at 50%~70% can be achieved, ensuring the storage quality of the wine.

[0049] Furthermore, after step S300, the method further includes: S400, controlling the fan to continue to operate, determining whether the internal humidity is within a preset humidity range, and when the internal humidity is higher than the preset humidity range, controlling the fan to be turned off.

[0050] When the refrigeration system stops working, the temperature in the refrigerator will rise as the cold air is lost. The delayed shutdown of the fan can blow the high-temperature air to the surface of the evaporator and the water receiving box, and evaporate the condensed water again and send it back to the box, so as to achieve the purpose of heating and humidifying the box. When the humidity sensor detects that the internal humidity is higher than the preset humidity range, the fan is turned off. When the humidity is lower than the preset humidity range, the fan is turned on. When the temperature sensor detects that the internal temperature is lower than the preset temperature range again and reaches the refrigeration condition, the above cycle is repeated. In this embodiment, the preset humidity range is 50%~70%. Within this humidity range, the storage quality of the wine can be guaranteed.

[0051] In this embodiment, the fan is a variable speed fan, and in step S200, when the fan is first turned on, the fan is controlled to run at the maximum speed, which can increase the air volume flowing through the evaporator, minimize the speed of humidity drop, and prevent the humidity in the wine cabinet from dropping rapidly.

[0052] In step S400, during the delayed shutdown process of the fan, the fan is also controlled to run at the maximum speed, blowing through the evaporator and the water receiving box at the maximum wind speed, so as to increase the humidity in the wine cabinet as quickly as possible.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
