Problems solved by technology

In this case, it can be confirmed that since bacteria and molds grow on the surface of washing scum, etc., the antibacterial components of the constituent parts of the washing machine cannot produce an antibacterial effect without contact with bacteria, molds, etc., even if the antibacterial components are added almost no effect
[0011] Furthermore, as in the washing machine of Patent Document 2, if the Ag ions required for anti-mildew are supplied to the extent that the anti-bacterial effect occurs, there is concern that the clothes will be blackened and the washing effect itself will be adversely affected.

Embodiment approach 1

[0028] figure 1 It is a sectional view showing the structure of the main part of the washing and drying machine in Embodiment 1 of the present invention, figure 2 It is an internal rear view showing the circulation air path and the rear of the outer tank of the washing-drying machine, image 3 It is a perspective view which shows the inside of the heat pump ventilation unit of this washing-drying machine.

[0029] like Figure 1 to Figure 3 As shown, in the washing and drying machine 1, a washing tub 2 for accommodating laundry is rotatably provided in the outer tub 3, and the direction of the rotation axis of the washing tub 2 is the horizontal direction or the horizontal direction as it goes to the rear. Slope down. The washing-drying machine 1 is equipped with a drying process in addition to each process of washing, rinsing, and dehydration.

[0030] The drying process is a process in which the laundry is dried by repeating the following operations: the air in the oute...

Embodiment approach 2

[0062] Figure 8 It is a longitudinal cross-sectional view of the washing-drying machine in Embodiment 2 of this invention. In Embodiment 2 of the present invention, about the same configuration, function, and effect as those in Embodiment 1, descriptions thereof will be omitted, and only different points will be described.

[0063] like Figure 8 As shown, the rotary drum 121 as the washing tank of the drum-type washing and drying machine is rotatably arranged in the water holding tank 123 as the outer tank. There are many through holes 122 thereon. The rotating shaft 124 is provided at the rotation center of the rotating drum 121 and is inclined with respect to the horizontal direction, and the axis direction of the rotating drum 121 is inclined downward from the front side to the back side. The motor 125 mounted on the back of the water tank 123 is connected to the rotating shaft 124, and the rotating drum 121 is driven to rotate in the forward and reverse directions. A...

Abstract

A washing and drying machine includes a washing tub for accommodating laundry, an outer tub holding the washing tub rotatably, a housing for elastically supporting the outer tub, a water feeder four supplying wash water to the outer tub, a heater for heating air in the outer tub, an air circulation duct for circulating the air in the outer tub via the heater, a blower for pressurizing and circulating the air in the air circulation duct, and an electrostatic atomizer placed in the air circulation duct for supplying electrostatically atomized particles into the washing tub and the outer tub.

Description

technical field [0001] The present invention relates to washing and drying machines. Background technique [0002] In recent years, attention has been paid to the hygienic environment of living spaces, and a large number of products with hygienic considerations such as sterilization and deodorization are distributed in the market. Among laundry products, washing and drying machines having functions of sterilizing and deodorizing clothing, cloth products, leather products, toys, and small articles are also on sale. [0003] Generally, these washing-drying machines are provided with a dedicated process in which an object is put into a washing tank and operated for several tens of minutes. Regarding the specific sterilization and deodorization methods, for example, various methods are involved, such as heating in a cylinder, using ozone, and using chemicals, but basically heating is performed. [0004] In addition, the inside of the washing machine drum is a concern as a plac...
