Problems solved by technology

[0005] However, the structure in which an armored heater is installed at the bottom of the tank to heat the washing water has the disadvantage of requiring a large amount of heat for heating.
In addition, it is necessary to implement safety devices against electric leakage, which is also disadvantageous in terms of cost.
However, in the structure in which warm air is blown into the rotating drum to heat the washing water, the stirring and rolling washing water must be heated, so the efficiency is extremely poor.

Embodiment 1

[0023] Hereinafter, Embodiment 1 of the washing machine with a drying function of the present invention will be described with reference to FIGS. 1 to 3 .

[0024] FIG. 1 is a schematic diagram schematically showing the configuration of main parts of a drum-type washing machine with a drying function. As shown in the figure, the cylindrical water storage tank 1 is elastically supported by an unillustrated elastic support device. Inside the water tank 1 , a drum 2 having a similar cylindrical shape is rotatably arranged, and forms a double tank together with the water tank 1 . The drum 2 is pivotally supported on two side walls of the tank 1 . With respect to the structure of the above-mentioned water tank 1 that is substantially non-porous and capable of storing water, the circumferential wall of the above-mentioned drum 2 has a large number of through holes 2a and a plurality of baffles (not shown), etc. Functions as a shared tank during operation, dehydration operation, an...

Embodiment 2

[0058] 6 and 7 show Embodiment 2 of the present invention. FIG. 6 is a schematic diagram showing a schematic configuration of main parts of a washing machine according to Embodiment 2. FIG. Fig. 7 is an action explanatory diagram schematically showing the operating state of the washing machine according to the second embodiment. The same parts as in the above-mentioned first embodiment are given the same symbols and their descriptions are omitted, and only the different parts will be described.

[0059] The second embodiment is characterized in that the laundry etc. are heated while a small amount of water is stored in the water tank 1 as means for imparting moisture during the preheating operation by warm air.

[0060] That is, arrows A and B in FIG. 6 indicate the flow of warm air during the warm-up operation, as in FIG. 1 . Also as shown in Figure 7(a), the drum 2 rotates at a high speed (400rpm), the blower fan unit 7 and the heater unit 8 constituting the warm air gener...

Abstract

The present invention provides a hot water cleaning effect without directly heating wash water by preheating laundry, a water tub and the like by means of hot air before feeding water for starting a wash cycle. This washing machine with the drying function is provided with the water tub 1, a drum 2, an air sending fan unit 7 and a heater unit 8 for generating the hot air, and a circulation route 4 circulatively feeding the hot air to the water tub 1 and the drum 2; and implements washing, rinsing, and spin-drying processes and the drying process by the hot air. This washing machine rotationary drives the drum 2 storing the laundry before feeding water in the wash cycle, circulatively feeds the hot air to execute a preheating operation of preheating the laundry, the water tub 1 and the like, and provides the hot water cleaning effect in the subsequent wash cycle.

Description

(1) Technical field [0001] The invention relates to a washing machine with a drying function provided with a warm air generator for drying laundry. (2) Background technology [0002] A so-called drum-type washing machine with a drying function that coaxially accommodates a rotating drum (drum) in a water tank arranged with the central axis facing the horizontal direction, because a relatively small amount of washing water is contained in the water tank and the drum The washing operation and rinsing operation can be carried out, so the water saving effect is good, and in the drying operation, the laundry in the drum is carried by the wall surface of the upper rotary side through the slow rotation centered on the axis facing the horizontal direction and makes It falls down and repeats such movements, during which the drying time can be shortened by blowing warm air, etc., so it is very convenient to use, and it has been rapidly popularized in recent years. [0003] In such a ...
