Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a constant temperature and humidity refrigerator with a defrosting water circulation structure. Background Art

[0002] Items such as red wine and cigars have requirements for the temperature and humidity of the storage environment. Too low or too high a temperature or humidity will shorten the storage time of red wine and cigars and reduce their quality. Therefore, for refrigerators that have high requirements for the temperature and humidity of the storage environment for storing red wine and cigars, it is often necessary to add constant temperature and humidity adjustment functions. For this reason, refrigerator products with constant temperature and humidity are launched on the market, such as a constant temperature and humidity device and a storage cabinet with constant temperature and humidity disclosed in patent number CN201821510621.4.

[0003] This type of constant temperature and humidity locker is based on the original refrigerator of the refrigerator, and an additional constant temperature and humidity device is installed at the bottom, which integrates a humidifying device, a heating device, an evaporator, a humidifying fan, a heating fan, and a water box. The condensed water formed by the evaporator is used to reduce the humidity, the humidifying fan is used to increase the humidity of the inner cavity, the refrigerator is used to reduce the temperature of the inner cavity, and the heating device is used to increase the temperature of the inner cavity, so as to adjust the inner cavity of the locker to a constant temperature and humidity.

[0004] The constant temperature and humidity device has a bulky and complex overall structure. For large refrigeration cabinets, the storage space occupied is not large; however, for small refrigerators for storing cigars and other items, the storage space occupied is large. Using it in a small refrigerator will greatly reduce the available storage space, and the product competitiveness will decline.

[0005] In addition, this type of humidification structure requires a drain port to be set at the water box for drainage and water replacement operations. The existing drain port is usually sealed with a rubber plug at the bottom of the water box. When the rubber plug is forgotten to be installed, the accumulated water will be completely discharged, resulting in the inability to perform humidification and constant humidity operations; when the rubber plug is completely blocked, the condensed water formed by the evaporator flows to the water box, which may cause overflow from the water box to other areas of the refrigerator. At the same time, the constant humidity humidification operation will consume water from the water tank and requires intermittent water addition, which makes it inconvenient for users to control the amount of water added to the water box. Therefore, further improvements are needed. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a constant temperature and humidity refrigerator with a defrosting water circulation structure.

[0017] Optionally, the heating device includes a heating unit and a heating installation frame; the heating installation frame is provided with air passages arranged at intervals; and the heating unit is arranged in the heating installation frame.

[0018] For small refrigerators, due to the small internal space, the airflow sent by the circulating fan can cover all areas of the refrigerator room and circulate, and be matched with a refrigerator and a heating device for constant temperature control; when the circulating airflow passes through the humidification tank, it can effectively carry the water evaporated from the humidification tank for humidification. When the humidity is high, the control center can start the refrigerator to cool and form condensed water, realizing the condensation-evaporation constant humidity adjustment process. The control center uses the three components of the refrigerator, the circulating fan and the heating device in conjunction with the humidification tank to achieve constant humidity and temperature regulation of a smaller refrigerator space.

[0019] The beneficial effects of the utility model are as follows: a guide channel is arranged in the cabinet, and the condensed water formed by the frost formed by the refrigerator can flow toward the humidification water tank through the guide channel after melting.

[0030] Example

[0031] Reference Figure 1 and Figure 2 The utility model provides a constant temperature and humidity refrigerator with a defrosting water circulation structure, comprising: a cabinet body 10, a cabinet door 20, a control center, and a refrigerator 30, a circulation fan 40 and a heating device 50 electrically connected to the control center;

[0032] The cabinet 10 is provided with a refrigerating chamber 60; the cabinet door 20 is movably mounted on the cabinet 10 and can cover the refrigerating chamber 60; the refrigerator 30 can cool the refrigerating chamber 60, and the heating device 50 can heat the refrigerating chamber 60; the circulating fan 40 can form a circulating airflow in the refrigerating chamber 60; a humidifying water tank 11 is provided at the bottom of the cabinet 10; the control center can control the refrigerator 30, the circulating fan 40 and the heating device 50 to work individually or in coordination;

[0033] The cabinet 10 is provided with a guide channel 12, through which condensed water can flow toward the humidification water tank 11; an overflow port 13 is provided on the path from the guide channel 12 to the humidification water tank 11; the overflow port 13 is a tubular column structure, and the top height is lower than the height of the bottom plate 14 of the cabinet 10.

[0034] For small refrigerators, due to the small inner cavity space, the airflow sent by the circulating fan 40 can cover various areas in the refrigerating chamber 60 and circulate, and be matched with the refrigerator 30 and the heating device 50 for constant temperature control; when the circulating airflow passes through the humidifying water tank 11, it can effectively carry the water evaporated from the humidifying water tank 11 for humidification. When the humidity is high, the control center can start the refrigerator 30 to cool and form condensed water, realizing the condensation-evaporation constant humidity adjustment process. The control center uses the three components of the refrigerator 30, the circulating fan 40 and the heating device 50 in coordination with the humidifying water tank 11 to achieve constant humidity and constant temperature adjustment of the smaller refrigerating chamber 60.

[0035] In the utility model, a guide channel 12 is arranged in the cabinet 10, and the condensed water formed by the frost formed by the refrigerator 30 after melting can flow toward the humidification water tank 11 through the guide channel 12. An overflow port 13 is arranged on the flow path. The top height of the overflow port 13 is lower than the bottom plate 14 of the cabinet 10. When the water level of the humidification water tank 11 is higher than the overflow port 13, it can be discharged from the overflow port 13 and will not overflow to other areas of the bottom plate 14 of the cabinet 10.

[0036] The overflow port 13 of the utility model can automatically discharge water that exceeds the height of the overflow port 13. On the one hand, a large amount of water can be retained in the humidifying water tank 11, which is convenient for adding a large amount of water and maintaining the humidifying constant temperature operation for a longer time. On the other hand, after the frost formed by the refrigerator 30 melts, if the water level of the humidifying water tank 11 is too high, it can also be discharged in time to avoid overflowing to other areas of the bottom plate 14.

[0037] In this embodiment, the refrigerator 30 is arranged on the back plate 15 of the inner shell of the cabinet 10, and the humidification water tank 11 is located on the bottom plate 14 of the inner shell of the cabinet 10; the guide channel 12 is arranged on the back plate 15, and the upper end of the guide channel 12 can collect condensed water; the lower end of the guide channel 12 extends toward the humidification water tank 11, and can make the condensed water flow to the humidification water tank 11.

[0038] Specifically, for the structure of a small cold food cabinet, the vacuum forming process is often used; it is difficult to directly make the humidifying water tank 11 with a deep depression in the transition area between the back plate 15 and the bottom plate 14 of the inner shell. A transition overflow groove 16 is provided at the lower end of the guide channel 12; the depression depth of the transition overflow groove 16 is shallower than the depression depth of the humidifying water tank 11; the overflow port 13 is provided in the transition overflow groove 16. The transition overflow groove 16 has a shallow depression depth, which can be used to process and manufacture the overflow port 13, forming a transition space for collecting condensed water, so that the condensed water is not easy to overflow to the surroundings, and can flow toward the humidifying water tank 11 more stably.

[0039] Furthermore, a bypass channel 17 is provided between the transition overflow channel 16 and the humidification water tank 11 . The top height of the overflow port 13 is higher than the bottom height of the bypass channel 17 .

[0040] In this embodiment, the refrigerator 30 is disposed above the guide channel 12, and the circulation fan 40 is disposed at the front side of the refrigerator 30; a condensation plate 31 is disposed in front of the circulation fan 40. When the refrigerator 30 is in operation, the low temperature area close to the refrigerator 30 can cause the moisture in the high humidity environment of the refrigerating chamber 60 to condense frost on the condensation plate 31, thereby reducing the humidity; when it is necessary to increase the internal humidity, the refrigerator 30 can be turned off, and the circulation fan 40 can be operated normally, so that the frost on the condensation plate 31 can be quickly melted, thereby increasing the humidity of the refrigerating chamber 60.

[0041] In this embodiment, a water receiving box 70 is disposed at the bottom of the cabinet 10 , and an overflow pipe 71 is disposed between the overflow port 13 and the water receiving box 70 .

[0042] In this embodiment, the heating device 50 is arranged above the circulation fan 40. The heating device 50 is arranged above the circulation fan 40, located in the upper area of ​​the back of the refrigerating chamber 60, and arranged close to the circulation fan 40; the heating device 50 is not likely to directly affect the items stored in the refrigerating chamber 60, and is not likely to affect the stability of the storage temperature at the bottom of the refrigerator; and the circulating airflow formed by the circulation fan 40 can quickly carry the heat of the heating device 50 to form a hot air flow, and perform uniform heat circulation heating treatment on the refrigerating chamber 60, so that the overall temperature rise of the inner cavity of the whole machine is adjusted uniformly and quickly.

[0043] Specifically, the arrangement height of the heating device 50 is higher than the arrangement height of the refrigerator 30. When the condensed water formed by the refrigerator 30 melts and flows downward, it will not pass through the heating device 50, and it is not easy to affect the normal operation of the heating device 50.

[0044] Furthermore, the heating device 50 includes a heating element unit 51 and a heating installation frame 52; the heating installation frame 52 is provided with air ducts arranged at intervals; the heating element unit 51 is arranged in the heating installation frame 52. The heating installation frame 52 provides an installation space for the heating element unit 51, and can also separate the heating element unit 51 from the refrigerating chamber 60 to prevent the heating element from directly contacting the items in the refrigerating chamber 60, thereby achieving a mutual protection effect. The circulating airflow passes through the heating element unit 51 through the air duct, and can quickly and evenly transfer heat to the refrigerating chamber 60.

[0045] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
