Problems solved by technology

The control device and control method can solve the problem that the heat pump system is easily overloaded by excessive temperature rise inside the equipment and cause equipment damage through the combined temperature-humidity data inside the equipment, and it is not necessary to stop the operation of the heat pump system when taking measures to cool and protect the equipment, so it will not Extended drying time
[0014] The present invention also provides a heat pump dry cabinet with the control device and control method. On the one hand, the combined temperature-humidity data inside the equipment solves the problem that the heat pump is easily overheated and the equipment is damaged due to excessive temperature rise inside the equipment, and the equipment can be improved as much as possible Work efficiency, on the other hand, there is no need for a special air duct inside the equipment that cannot hang clothes, which makes the structure simpler, the circulation wind resistance is smaller, the circulation air volume is larger, the shape is smaller, the effective volume is larger, and the clothes that can be stored are more more, faster drying

Abstract

The invention provides an overload protection control device of a heat pump type dry wardrobe, a control method of the device, and a dry wardrobe with the device, wherein, the control device comprises a temperature sensor used for measuring the temperature of circulated air in the dry wardrobe, a humidity sensor used for measuring the humidity of the circulated air in the dry wardrobe, a calculating device connected with the temperature sensor and the humidity sensor, and external forced draft ventilation equipment connected with and controlled by the calculating device. When the temperature-humidity of the circulated air in the wardrobe exceeds or is close to a safety range, the external forced draft ventilation equipment is started to reduce temperature, therefore, the damage to the equipment caused by the overload of a heat pump system can be avoided without stopping the operation of the heat pump system, the structure is simple and the drying efficiency is higher.

Description

technical field [0001] The present invention relates to clothes drying equipment, especially a drying cabinet equipped with an overload protection control device for a heat pump system, and also relates to an overload protection control method used in this drying cabinet and other similar heat pump drying equipment, and a device using the control method . Background technique [0002] One of the most common clothes drying equipment currently on the market is to blow the air into the drying room after being heated by electricity or gas. The hot air and clothes are only discharged into the atmosphere after a short-term heat exchange, and the energy consumption is high. Moreover, the contact area between hot air and clothing is small, moisture is not easy to seep out, and it takes a long time to dry. This kind of drying equipment is easy to cause local overheating to damage the equipment during use, and it is also easy to damage clothes due to local overheating. [0003] Rela...
