Problems solved by technology

[0007] In addition, there is a problem in the heat pump that it takes time for the rising edge from the start of the compressor until the temperature of the condenser rises to a certain high temperature and the evaporator can cool and dehumidify the moisture in the circulating air

Embodiment Construction

[0044] Refer to the following figure 1 A first embodiment of the present invention will be described through Fig. 9 .

[0045] First, in figure 1 , shows the overall structure of a washing and drying machine, particularly a drum type (horizontal axis) washing and drying machine. A water tank A2 is arranged inside the cabinet A1, and a rotating tank (drum type) is arranged inside the water tank A2. ) A3.

[0046] Above-mentioned water tank A2 and rotating tank A3 all form cylindrical shape, on the front side ( figure 1 There are respective openings A4 and A5 on the end face of the middle left side). Wherein, the opening A5 of the spin tank A3 is used for taking out and putting in laundry (hereinafter simply referred to as laundry or clothes), and the opening A4 of the water tank A2 surrounds it. The opening A4 of the water tank A2 is connected to the opening A6 for taking out and putting in laundry formed on the front part of the cabinet A1 through a bellows A7, and a door ...

Abstract

To provide a clothes drying machine with a heat pump for drying the clothes, capable of preventing the temperature of a condenser and the pressure of a refrigerant on the high-pressure side in the latter half period of the drying operation from becoming preset values or higher, and capable of increasing the speed of temperature rise in a drying chamber in the initial period of the drying operation. Outside air is introduced during the drying operation from an outside air intake disposed at an area between a place where an evaporator is disposed and a place where the condenser is disposed in a ventilation path, so that the temperature of the condenser and the pressure of the refrigerant on the high-pressure side in the latter half of the drying operation will not become preset values or higher. As a result, it is not necessary to reduce the labor of a compressor, and therefore, a high drying performance can be achieved in the clothes drying machine. By making a PTC heater provided at the outside air intake generate heat in the initial period of the drying operation, outside air can be introduced into the ventilation path while heated by the PTC heater. Accordingly, the speed of temperature rise in the drying chamber can be increased in the initial period of the drying operation, and therefore, the drying operation can be finished early.

Description

technical field [0001] The present invention relates to a clothes dryer which uses a heat pump to dry clothes. Background technique [0002] Conventionally, among clothes dryers, a dryer having a heat pump for drying clothes has attracted attention as a dryer that has good drying performance and is effective in saving energy. In this clothes dryer with a heat pump, the air in the drying room containing the clothes is circulated through the ventilation path of the heat pump equipped with an evaporator and a condenser connected to the compressor cycle, and the evaporator therein is used for air circulation. Cooling and dehumidification, heat the air by the condenser, then send it into the drying chamber one by one, then make the air that gets moisture from the clothes pass through the ventilation path, and by repeating the above process, the clothes are gradually dried (for example, refer to patent documents 1, 2 , 3). [0003] Therefore, the moisture generated when drying c...
