Abstract

PURPOSE:To make available a dehumidifier designed for energy-saving operation, which enables the power consumption to be reduced, by providing a switch and a temperature regulator, the former for controlling a heater and the latter for applying power to the heater only when the temperature of the air sucked into the apparatus falls below a specified point. CONSTITUTION:When a power supply switch 24 and a drying switch 2 are on, the air sucked into the housing cabinet is cooled to undergo dehumidification at a cooler 12, heated at a radiator 13, and discharged through an outlet 16 which is heated by a heater 1 further to a higher temperature. In the controlled chamber, the humidity declines whereas the temperature rises, so that the relative humidity declines, making the drying time of clothing much shorter than when the temperature is low. On the other hand, a temperature regulator acts to put the heater 1 to work only when the temperature of the air sucked into the cabinet 10 is below a specified point; the heater 1 does not work when the temperature of the controlled chamber is high and the relative humidity is so low as to the independent dehumidification efficient for drying. Therefore, this apparatus contributes to economization in energy, making it possible to reduce the power consumption.

[0009]

However, in the conventional dehumidifier, the temperature of the air blown from the outlet (16) rises only to the temperature of the radiator (13), and the dehumidification operation is performed especially at low room temperature. There is a problem that it takes a very long time to dry clothes (laundry) and the like only by drying.

An object of the present invention is to provide a dehumidifier that solves the above problems.

[0011]

A dehumidifier according to the present invention is provided with a compressor, a cooler, a radiator, a blower, a dehumidifying water tank and an overflow preventive device in a cabinet, and is sucked into the cabinet by the blower. This is a dehumidifier that cools and dehumidifies air with a cooler, reheats it with a radiator, and then sends it out of the cabinet.In this cabinet, a heater is placed in the passage for the dehumidified air that has passed through the radiator. In addition, a switch for operating the heater and a temperature controller for operating the heater only when the temperature of the air sucked into the cabinet becomes equal to or lower than a set temperature are provided.

[0012]

When the switch for operating the heater is closed, the heater is energized, the dehumidified air that has passed through the radiator is heated, and then blown out from the air outlet, so that the temperature inside the room where the dehumidifier is installed becomes high. Therefore, as the indoor humidity decreases, the saturated humidity also increases, the relative humidity decreases, and the drying efficiency of clothes and the like improves. Further, due to the function of the temperature controller, the heater is activated only when the temperature of the air sucked into the cabinet falls below the set temperature. Therefore, when the room temperature is high and the relative humidity in the room is lowered to such an extent that sufficient drying efficiency can be obtained only by dehumidifying, the heater does not operate. As a result, power consumption is significantly reduced, and energy saving operation is possible.
