Embodiment 1

[0028] figure 1 is a perspective view showing the drum type washing machine 100 of the present invention, figure 2 It is a side view showing the internal structure of front-loading-type washing machine 100 . use figure 1 and figure 2 , the structure and operation of the front-loading washing machine 100 will be described.

[0029] constitute figure 1 The casing 1 of the outer contour of the drum type washing machine 100 shown is installed on the base 1a, and is formed by the left and right side plates 1b ( figure 1 Only the right side panel is shown in ), front cover 1c, rear cover 1d (refer to figure 2 ), upper cover 1e, and lower front cover 1f. A water supply hose connection port 30 for supplying water from a water tap to the front-loading washing machine 100 is provided on the upper cover 1e. The box body 1 forms a box-shaped outer frame including the base 1a, and has sufficient strength as the outer frame.

Embodiment 2

[0055] Next, refer to Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 as well as Figure 9 Example 2 will be described in detail.

[0056] In addition, since front-loading-type washing machine 100 has basically the same structure as that of Embodiment 1, different parts will be described below.

[0057] Figure 4 A central cross-sectional view of the drum-type washing machine 100 of the present embodiment is shown, Figure 5 A state in which the outer tank 11 is statically supported is shown. In Embodiment 2, the outer groove side anti-falling member 31 is arranged in front of the outer groove side rear spring bracket 10c, and the box side anti-falling member 31a is arranged in front of the outer groove side anti-falling member 31. The distance between the outer tank side anti-off part 31 and the box side anti-off part 31a is as follows: before the outer tank 11 is moved forward from the state where the outer tank 11 is statically supported, the first suspensi...

Abstract

The invention provides a drum type washing machine and a drum type washing and drying machine that are capable of ensuring arrangement space of hanging mechanisms of an outer tank when the diameter ofthe outer tank is enlarged due to an increase in washing capacity, interference between the outer tank and a wire coil part of a suspension mechanism can be prevented when the outer tank vibrates, and generation of noise can be prevented. The drum type washing machine is provided with a rotatable drum of which the horizontal axis or an inner side is inclined downwardly, an outer tank in which thedrum is built and stores wash water, a tank body in which the outer tank is built, and at least two sets of suspension mechanisms having upper portions supporting an upper tank at a front part and arear part; a first hanging mechanism is used for suspending an outer tank to a front part and an upper part, a coil portion of the first hanging mechanism is located in front of a portion of the outertank with the largest diameter, the second hanging mechanism is located behind the first hanging mechanism, and a connection portion between the second hanging mechanism and the outer tank is locatedbehind a connection portion between the first hanging mechanism and the outer tank, and a connection portion between the second hanging mechanism and the tank body is positioned behind a connection portion between the second hanging mechanism and the outer tank.

Description

technical field [0001] The invention relates to a drum type washing machine for washing and dehydration and a drum type washing and drying machine for washing, dehydration and drying. Background technique [0002] In the drum type washing machine, an outer tank for storing water is built in the cabinet, and a drum for putting clothes in is built in the outer tank. The drum type washing machine performs each process of washing, rinsing, and dehydration. When the clothes are turned to one side during dehydration, if the drum rotates at a high speed, a large centrifugal force is generated, resulting in a large vibration. In order to reduce this large vibration, the lower part of the outer tank is supported by a suspension consisting of a spring and a damper. And, in order to prevent the outer tank from falling down in the front-rear direction, an elastic member such as a tension spring is used to connect the upper part of the outer tank and the box to support the outer tank i...
