Description

Technical Field

[0001] This utility model relates to the field of refrigerators, and in particular to a large-capacity constant temperature and humidity refrigerator with uniform heat circulation. Background Technology

[0002] Items such as red wine and cigars have specific temperature and humidity requirements for storage. Temperatures that are too low or too high will shorten the shelf life of red wine and cigars and reduce their quality. Therefore, refrigerated cabinets for storing red wine and cigars, which require precise temperature and humidity control, often need to incorporate temperature and humidity regulation functions. As a result, refrigerated cabinets with constant temperature and humidity control have been introduced to the market, such as the constant temperature and humidity device and storage cabinet disclosed in patent number CN201821510621.4.

[0003] This type of temperature and humidity control cabinet, in addition to the original refrigeration unit of a refrigerator, has an additional temperature and humidity control device added to the bottom, integrating a humidifier, a heating unit, an evaporator, a humidifying fan, a heating fan, and a water tank. It uses the condensate from the evaporator to lower humidity, the humidifying fan to increase humidity within the cavity, the refrigeration unit to lower the internal temperature, and the heating unit to raise the internal temperature, thus achieving constant temperature and humidity control within the cabinet.

[0004] However, this structure places the heating element at the bottom of the refrigerator, causing heat to accumulate there. This leads to localized high temperatures instead of rapid heat dissipation, affecting the stability of the storage temperature at the bottom and hindering the uniform and rapid temperature adjustment of the entire interior. Furthermore, as the refrigerator's volume increases, even with a simple humidifier or heater fan, the circulating airflow cannot effectively and evenly cover the entire storage cavity, resulting in poor temperature and humidity control for large-capacity refrigerators. Therefore, further improvements are needed. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a large-capacity constant temperature and humidity refrigerator with uniform heat circulation.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a large-capacity constant temperature and humidity refrigerator with uniform heat circulation, including: a cabinet body, a cabinet door, a control center, and a refrigerator, a heating device, a main circulation fan and a downflow fan electrically connected to the control center;

[0007] The cabinet body encloses a cold storage compartment; the cabinet door is movably installed on the cabinet body and can cover the cold storage compartment; the refrigerator can cool the cold storage compartment, and the heating device can heat the cold storage compartment; the main circulation fan blows air into the cold storage compartment, which can form a circulating airflow in the cold storage compartment; a humidifying water tank is provided at the bottom of the cabinet body; the control center can control the refrigerator, heating device, main circulation fan and downflow fan to work individually or in combination.

[0008] The heating device is positioned above the main circulating fan; the downward fan is positioned close to the heating device and can blow air downwards.

[0009] Optionally, the inner wall of the cabinet is provided with a vertically extending air guide groove, and the downward fan is located at the top of the air guide groove.

[0010] Optionally, the heating device includes a heating element unit and a heating mounting frame; the heating mounting frame has a plurality of spaced air passage slots; the heating element unit is disposed on the heating mounting frame; a downward air outlet aligned with the air guide slots is provided below the heating mounting frame, and the downward fan is mounted on the downward air outlet.

[0011] Optionally, the heating mounting frame has an "L"-shaped sheet metal structure, is installed above the interior of the refrigerator compartment, and forms a cuboid-shaped heating mounting cavity with the inner wall of the refrigerator compartment.

[0012] Optionally, the heating element unit is a PTC heating element.

[0013] Optionally, an upward fan is provided above the humidifying water tank, and the upward fan can blow air upwards.

[0014] Optionally, a humidification mounting frame is provided above the humidification water tank, and the upward fan is mounted on the humidification mounting frame.

[0015] Optionally, the inner wall of the cabinet is provided with a vertically extending condensate drain channel, which extends from below the refrigeration unit toward the humidification water tank.

[0016] Optionally, the cooler includes a semiconductor cooling element; the main circulation fan is disposed in front of the semiconductor cooling element.

[0017] The airflow from the main circulating fan circulates throughout the refrigerator compartment, working in conjunction with the refrigeration and heating units for temperature control. As the circulating air passes through the humidification tank, it effectively carries away water that evaporates, humidifying the space. When humidity is too high, the control center activates the refrigeration unit to generate condensate, achieving a condensation-evaporation process for humidity regulation. By utilizing the refrigeration unit, main circulating fan, and heating unit in conjunction with the humidification tank, the control center can achieve constant temperature and humidity control in a relatively small refrigerator compartment.

[0018] The beneficial effects of this invention are as follows: The heating device is positioned above the main circulating fan, in the upper back area of ​​the refrigerator compartment, close to the main circulating fan. This design minimizes the direct impact on items stored inside the refrigerator compartment and maintains stable storage temperatures at the bottom of the refrigerator. Furthermore, a downward-flowing fan is located near the heating device, directing air downwards to expel hot air accumulated at the top of the refrigerator compartment, creating a hot air circulation flow. The combination of the side-directed, centrally located main circulating fan and the downward-flowing fan forms a dual circulation pattern of main airflow and hot airflow. Even with a large-capacity refrigerator structure, this effectively covers the entire refrigerator compartment, providing uniform heat circulation and heating, resulting in a rapid and even temperature adjustment throughout the entire interior.

[0030] Example

[0031] Reference Figures 1 to 3 The present invention proposes a large-capacity constant temperature and humidity refrigerator with uniform heat circulation, comprising: a cabinet body 10, a cabinet door 20, a control center, and a refrigerator 30, a heating device 40, a main circulation fan 50 and a downflow fan 60 electrically connected to the control center.

[0032] The cabinet 10 is surrounded by a refrigerator compartment 70; the cabinet door 20 is movably installed on the cabinet 10 and can cover the refrigerator compartment 70; the refrigerator 30 can cool the refrigerator compartment 70, and the heating device 40 can heat the refrigerator compartment 70; the main circulation fan 50 blows air into the refrigerator compartment 70, which can form a circulating airflow in the refrigerator compartment 70; a humidifying water tank 11 is provided at the bottom of the cabinet 10; the control center can control the refrigerator 30, the heating device 40, the main circulation fan 50 and the downflow fan 60 to work individually or in combination.

[0033] The heating device 40 is positioned above the main circulating fan 50; the downward fan 60 is positioned close to the heating device 40 and can blow air downwards.

[0034] The airflow from the main circulating fan 50 can circulate throughout all areas of the refrigerator compartment 70, and works in conjunction with the refrigerator 30 and heating device 40 to maintain a constant temperature. When the circulating airflow passes through the humidifying water tank 11, it effectively carries away water from the tank for humidification. When the humidity is too high, the control center can activate the refrigerator 30 to cool and form condensate, achieving a condensation-evaporation process for constant humidity control. By utilizing the refrigerator 30, the main circulating fan 50, and the heating device 40 in conjunction with the humidifying water tank 11, the control center can achieve constant humidity and temperature control in the relatively small refrigerator compartment 70.

[0035] In this invention, the heating device 40 is positioned above the main circulating fan 50, located in the upper back area of ​​the refrigerator compartment 70, close to the main circulating fan 50. The heating device 40 is less likely to directly affect the items stored in the refrigerator compartment 70, and less likely to affect the stability of the storage temperature at the bottom of the refrigerator. Furthermore, a downward-flowing fan 60 is also positioned near the heating device 40, which directs airflow downwards, sending the hot air accumulated at the top of the refrigerator compartment downwards, forming a hot air circulation airflow. The side-directed, centrally located main circulating fan 50, combined with the downward-flowing fan 60, forms a dual circulation pattern of main airflow and hot airflow. For a large-capacity refrigerator structure, this effectively covers the area inside the refrigerator compartment 70, providing uniform heat circulation and heating, resulting in a uniform and rapid overall temperature adjustment of the entire interior.

[0036] In this embodiment, the heating device 40 is arranged at a higher height than the refrigerator 30. When the condensate formed by the refrigerator 30 melts and flows downwards, it will not pass through the heating device 40, thus minimizing its impact on the normal operation of the heating device 40.

[0037] In this embodiment, in order to better guide the hot airflow to the bottom of the refrigerator compartment 70, rather than diffusing to the sides in the middle, the inner wall of the cabinet 10 is provided with a vertically extending air guide groove 12, and the downward fan 60 is located at the top of the air guide groove 12.

[0038] In this embodiment, the heating device 40 includes a heating element unit 41 and a heating mounting frame 42. The heating mounting frame 42 has several spaced-apart air ducts 43. The heating element unit 41 is disposed on the heating mounting frame 42. A downward air outlet 45 aligned with the air guide groove 12 is provided below the heating mounting frame 42, and a downward fan 60 is installed at the downward air outlet 45. The circulating airflow passes through the air ducts and the heating element unit 41, thus quickly and evenly transferring heat to the refrigerator compartment 70.

[0039] Specifically, heating element unit 41 is a PTC heating element.

[0040] In this embodiment, the heating mounting frame 42 has an "L"-shaped sheet metal structure, is installed inside the upper part of the refrigerator compartment 70, and forms a cuboid-shaped heating mounting cavity 44 with the inner wall of the refrigerator compartment 70. The heating mounting frame 42, made of "L"-shaped sheet metal structure, has low manufacturing cost and can effectively match the corners of the inner wall of the box to form a cuboid-shaped heating mounting cavity 44.

[0041] In this embodiment, an upward fan 80 is provided above the humidifying water tank 11, which blows air upwards. The upward fan 80 is close to the humidifying water tank 11, which can further send water vapor upwards to form a humidifying circulating airflow, accelerate the circulation of water vapor from the bottom to the top of the refrigerator compartment 70 of the large-capacity refrigerator, effectively cover the area inside the refrigerator compartment 70, and speed up the humidification efficiency.

[0042] Specifically, a humidification mounting frame 81 is provided above the humidification water tank 11, and an upward fan 80 is installed in the humidification mounting frame 81.

[0043] In this embodiment, in order to allow the condensate formed at the cooler 30 to flow back and be collected in the humidification water tank 11 to form a constant humidity regulation of condensate-humidification water vapor, the inner wall of the cabinet 10 is provided with a vertically extending condensate guide channel 13, which extends from below the cooler 30 toward the humidification water tank 11.

[0044] In this embodiment, the cooler 30 includes a semiconductor cooling element; the main circulation fan 50 is disposed in front of the semiconductor cooling element. The cooling and heating operations of the semiconductor cooling element and the PTC heating element are more accurate and reliable.

[0045] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
