Constant-temperature and constant-humidity cigar cabinet and control method thereof

Abstract

The invention provides a constant-temperature and constant-humidity cigar cabinet and a control method thereof. The constant-temperature and constant-humidity cigar cabinet comprises an inner container, a temperature control device, a humidifying device and an air guide device, the temperature control device comprises a water tank, a refrigerating assembly and a heating assembly; the humidifying device is used for pumping out water in the water tank and spraying the water on the surface of the heat exchanger to form a high-humidity environment at the heat exchanger; the air guide device comprises a first air guide plate, a second air guide plate and an air inducing fan, a first area is defined by the first air guide plate and the inner container, a second area is defined by the first air guide plate, the second air guide plate and the inner container, and a third area is formed in the space, located in front of the second air guide plate, in the inner container, upward flowing air flow is generated in the first area through the induced draft fan, the air flow passes through the large hole to enter the second area after being premixed by the first area, and passes through the small hole to enter the third area after being remixed and buffered by the second area. The method has the advantages of being good in air guide effect, good in temperature and humidity balance and accurate in temperature and humidity control.

Description

technical field [0001] The invention belongs to the technical field of cigar preservation, and in particular relates to a constant temperature and humidity humidor and a control method thereof. Background technique [0002] The storage and maintenance of cigars are generally placed in an environment with a specific temperature and humidity. Generally speaking, the storage and maintenance conditions of cigars are that the temperature is between 16°C and 22°C, and the humidity is between 60% and 80%. between. [0003] At present, cigars are mostly stored in wooden humidors or wine cabinets. In the refrigeration process of the prior art, due to the need to meet the temperature requirements in the box, the evaporation temperature on the surface of the evaporator is often below 0°C, which must be lower than The dew point temperature of the air in the cabinet, so the humidity in the cabinet will inevitably decrease. When the temperature in the cabinet reaches the target value, th...

Problems solved by technology

[0003] At present, cigars are mostly stored in wooden cigar boxes or wine cabinets. In the refrigeration process of the prior art, due to the need to meet the temperature requirements in the box, the evaporation temperature on the surface of the evaporator is often below 0°C, which must be lower than The dew point temperature of the air in the cabinet, so the humidity in the cabinet will inevitably decrease, and when the temperature in the cabinet reaches the target value, the compressor will stop, and the surface temperature of the evaporator will rise rapidly, which is higher than the dew point temperature of the air in the cabinet, so that the humidity in the cabinet Rising, the humidity in the cabinet will fluctuate greatly after repeated repetitions, and the temperature and humidity in the box or cabinet cannot be well controlled and adjusted, and the storage conditions required for cigars cannot be met, and long-term storage and maintenance of cigars cannot be achieved. purpose of smoke

[0004] Cigar cabinets in the prior art use the method of evaporator / heater + fan to supply air, such as the internal environment adjustment device of the humidor disclosed in Chinese patent 201821536930.9. The wind blows directly towards the space inside the cabinet, resulting in direct blowing at the position near the fan outlet, which is greatly affected by the temperature, and the temperature adjustment is not obvious at the position far away from the fan outlet. When the humidor has a large storage space, the cabinet is different. The temperature varies greatly across regions, and the quality of cigars is affected by the location where they are stored.
