Temperature and moisture preservation cabinet

Abstract

The invention discloses a temperature and moisture preservation cabinet. An air inlet channel and an air outlet channel are formed in two sides of the cabinet body and communicated with the cabinet body, an upper air channel is respectively communicated with the air inlet channel and the air outlet channel, temperature and moisture sensors are arranged in the upper air channel, an air heating PTC (positive temperature coefficient) thermistor is arranged at an air outlet of a circulating fan, the top end of the air inlet channel is communicated with an air outlet of the circulating fan, a steam heating PTC thermistor and a box-shaped radiator contacting with the top of the steam heating PTC thermistor are arranged at an air inlet of the circulating fan, a water storage box is arranged at the bottom of the air outlet channel and communicated with the box-shaped radiator through a water pump and a water inlet pipe, and the temperature and moisture sensors, the air heating PTC thermistor, the steam heating PTC thermistor and the water pump are respectively connected with a control system. The temperature and moisture preservation cabinet solves the problem that an existing product cannot accurately control moisture, the temperature and the moisture can be respectively and independently controlled, a water tank is arranged at the inner bottom of the cabinet, water in the water tank can be effectively prevented from entering an electric box and causing dangerous accidents when in carrying and moving.

Description

technical field [0001] The invention relates to a heat preservation and moisturizing cabinet. Background technique [0002] At present, known heat preservation and moisturizing cabinets usually use top hot air circulation, and at the same time place a water storage tank on the top of the cabinet. The water in the water tank is heated by the air in the cabinet or by a special electric heating tube. , the relative humidity in the cabinet is ultimately related to the temperature and cannot be controlled independently. When the water tank is heated, due to the large amount of water in the water tank, the speed of steam generation is slow. Once it reaches boiling and the humidity in the cabinet reaches the set value, the water tank will continue to generate a large amount of steam, making the relative humidity seriously exceed the set value. In general, there is a problem that the water storage and humidification scheme of the water tank cannot be accurately controlled. Conten...
