Description

TECHNICAL FIELD

[0001] The utility model relates to the field of dehumidification equipment, specifically relates to a rotary dehumidifier. BACKGROUND

[0002] One of the core working components of the rotary dehumidifier is the heater, which mainly provides heat for the regeneration process of the moisture-absorbing rotary wheel, so that the water adsorbed on the rotary wheel can be separated from the rotary wheel under the action of high temperature, thereby restoring the adsorption capacity of the rotary wheel and ensuring the continuous and stable operation of the dehumidifier. As a key component for ensuring the safe and stable operation of the heater and the normal operation of the entire dehumidifier system, the temperature protector is crucial.

[0003] However, many current rotary dehumidifiers have not achieved the ideal optimization state in the setting of the temperature protector. The existing temperature protectors are not installed at the true highest temperature position of the heater. This leads to the fact that when local overheating occurs inside the heater during actual operation, the temperature protector may not be able to timely and accurately perceive the dangerous high temperature signal, and therefore needs to be improved.

[0035] In the design of the traditional rotary dehumidifier, the temperature detection module is usually arranged on the upper part of the main plate 4121, but since the upper part of the main plate 4121 has cold air entering through the first air outlet, and is the highest temperature part of the main plate 4121, and the temperature detection module cannot be well protected from high temperature, it is easy to cause the temperature to be too high, thereby causing damage to the heater.
