A constant temperature and humidity cigar cabinet and its control method

Abstract

The invention provides a constant temperature and humidity cigar cabinet and a control method thereof, comprising an inner tank and a temperature control device, a humidification device and an air guide device arranged in the inner tank; the temperature control device includes a water tank, a refrigeration component and a heating component; The humidifying device is used to extract the water in the water tank and spray it on the surface of the heat exchanger to form a high-humidity environment at the heat exchanger; the air guiding device includes a first air guiding plate, a second air guiding plate and an air guiding fan, A first area is enclosed between the first air deflector and the inner liner, and a second area is enclosed between the first air deflector, the second air deflector and the inner liner, and the inner liner is located in front of the second air deflector The space formed the third area, using the induced draft fan to generate an upward flow of air in the first area, the air flow through the pre-mixing in the first area through the large hole into the second area, after the second area remixing and buffering Then enter the third area through the small hole. The invention has the advantages of good air guiding effect, good temperature and humidity balance, and precise 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 cigar cabinet and a control method thereof. Background technique [0002] The storage and maintenance of cigars are generally placed in a specific temperature and humidity environment. Generally speaking, the storage and maintenance conditions of cigars are that the temperature is required to be between 16°C and 22°C, and the humidity is required to be between 60% and 80%. between. [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 of the evaporator surface is often below 0 °C, and this temperature 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...

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.
