[0018] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0019] Combination Figure 1-Figure 3As shown, the utility model discloses an independent dual-air duct cigar storage cabinet (also referred to as "cigar cabinet"), comprising a cabinet body 1 with a storage cavity, a refrigeration assembly 2 arranged on the cabinet body 1, an evaporator 3 connected to the refrigeration assembly 2, a heating assembly 4 and an air duct plate 5 with a plurality of ventilation holes 51, the air duct plate 5 is fixed to the inner wall of the storage cavity, and the evaporator 3 and the heating assembly 4 are located between the air duct plate 5 and the inner wall of the storage cavity.

[0020] The main improvement means of the utility model include: a cooling fan 6 and a heating fan 7 are provided above the evaporator 3; a cooling air duct and a heating air duct are formed between the air duct plate 5 and the inner wall of the storage chamber; the cooling air duct is connected between the cooling fan 6 and the ventilation hole 51, and the evaporator 3 is located in the cooling air duct; the heating air duct is connected between the heating fan 7 and the ventilation hole 51, and the heating component 4 is located in the heating air duct and is arranged above the evaporator 3.

[0021] By forming independent cooling air ducts and heating air ducts between the air duct plate 5 and the inner wall of the storage cavity, the cooling air duct and the heating air duct are independent of each other, so that the heating component 4 uses the heating air duct to provide heating, and the hot air will not pass through the cooling air duct, so that the condensed water on the surface of the evaporator 3 in the cooling air duct will not enter the storage cavity as the hot air evaporates, thereby solving the technical problem of whether the humidity in the cabinet 1 will increase when the heating component 4 is used to heat and adjust the temperature of the storage cavity.

[0022] Furthermore, by arranging the heating component 4 above the evaporator 3 , it is prevented that the condensed water generated by the evaporator 3 drips onto the heating component 4 , thereby protecting the heating component 4 and improving the safety of the use of the heating component 4 .

[0023] It is understandable that a temperature sensor is provided in the cabinet 1 to detect the actual temperature of the storage cavity. When the actual temperature is lower than the preset storage temperature, the heating component 4 needs to be activated for heating. When the actual temperature of the storage cavity is higher than the storage temperature, the refrigeration component 2 needs to be activated for cooling.

[0024] The cooling fan 6 is an air supply fan. When the cooling component 2 needs to be started for cooling and cooling, the cooling component 2 and the cooling fan 6 are started. Under the action of the cooling fan 6, the air in the storage cavity is sucked in and sent into the cooling air duct. After flowing through the surface of the evaporator 3 for cooling, the cold air is then sent back to the storage cavity from the ventilation holes 51 of the air duct plate 5, thereby quickly reducing the air at various positions of the storage cavity.

[0025] A plurality of ventilation holes 51 are provided on the air duct plate 5 and are located on two opposite vertical sides of the evaporator 3. Such a configuration is conducive to the airflow flowing through the surface of the evaporator 3 to cool down and then quickly discharged from different heights and directions in the storage cavity, which is conducive to maintaining a balanced temperature at various locations in the storage cavity and also to quickly cooling down various locations in the storage cavity.

[0026] The heating fan 7 is an exhaust fan. When it is necessary to start the heating component 4 for heating and temperature raising, the heating fan 7 and the heating component 4 are started, and the air in the storage cavity is sucked in from each ventilation hole 51, flows through the heating component 4 to be heated and heated to become a hot air flow, and then is sent back to the storage cavity from the heating fan 7, so that the air in the storage cavity can be heated. In the heating process, since the heating air duct and the cooling air duct are independent of each other, the hot air flow does not need the cooling air duct, so the hot air flow will not pass through the evaporator 3, so that the hot air flow will not vaporize the condensed water remaining on the surface of the evaporator 3 and bring it into the storage cavity, thereby achieving the goal of using the heating component 4 for heating and temperature raising without increasing the humidity in the cabinet 1 at the same time, which is conducive to simplifying the temperature and humidity regulation of the cabinet 1 so that the temperature and humidity regulation do not affect each other.

[0027] Furthermore, a first circulation fan 52 and a second circulation fan 53 are provided on the air duct plate 5. The first circulation fan 52 is located below the evaporator 3, while the second circulation fan 53 is located above the evaporator 3. The first circulation fan 52 and the second circulation fan 53 are in a normally open state. The first circulation fan 52 and the second circulation fan 53 are used to promote the circulation of the upper and lower layers of air in the cabinet 1, ensuring that the air at each position in the cabinet 1 maintains a balanced temperature and humidity condition to improve the storage effect of cigars.

[0028] Preferably, the first circulation fan 52 and the second circulation fan 53 are staggered and disposed at two diagonal positions of the evaporator 3 .

[0029] Furthermore, the air outlets of the first circulation fan 52 and the second circulation fan 53 are both arranged upward, so that the first circulation fan 52 and the second circulation fan 53 suck air from the front side and blow it upward, which is beneficial to increase the convection between the lower air and the upper air of the cabinet 1 to balance the air.

[0030] Of course, a humidifying assembly 8 is provided at the bottom of the storage chamber, and the first circulation fan 52 is located above the humidifying assembly 8 .

[0031] It is understandable that a humidity sensor is also provided in the cabinet 1. When the humidity sensor detects that the humidity in the cabinet 1 is lower than the storage humidity of the cigars, the humidification component 8 needs to be started to perform humidification processing; conversely, when the humidity sensor detects that the humidity in the cabinet 1 is higher than the storage humidity of the cigars, the refrigeration component 2 needs to be started to provide refrigeration, and when the air in the storage cavity flows through the evaporator 3, part of the moisture is condensed on the evaporator 3 to perform dehumidification processing.

[0032] Generally speaking, the humidification assembly 8 comprises a water tank and a humidification fan located above the water tank. The humidification fan is used to generate airflow to the water in the water tank to accelerate the evaporation of the water in the water tank to achieve humidification.

[0033] In order to improve the evaporation efficiency of the water in the water tank by the humidifying fan, the humidifying fan includes a first humidifying fan blowing air toward the water tank and a second humidifying fan sucking air from the water tank. The first humidifying fan and the second humidifying fan cooperate to greatly improve the humidification efficiency.

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
