Problems solved by technology

[0003] However, the treatment agent tank is easily affected by the shape of the front-loading washing machine
Therefore, if the capacity of the processing agent tank is increased, there is a problem that the volume including the height of the product will increase.

no. 1 approach

[0017] like figure 2 as well as image 3 As shown, a front-loading washing machine 10 includes an outer case 11 , a door 12 , a washing tub 13 , a spin tub 14 , and a treatment agent box 15 . In this specification, the side of the door 12 is referred to as the front with respect to the outer box 11 . Also, let the horizontal direction perpendicular to the front-back direction be the left-right direction, and let the gravitational direction perpendicular to the front-back direction and the left-right direction be the up-down direction. The central axis of washing tub 13 of front-loading type washing machine 10 and the axis serving as the rotation center of rotary tub 14 are both inclined with respect to the ground. Specifically, washing tub 13 and spin tub 14 are inclined so as to be positioned higher as they are closer to the front on the side of door 12 . In addition, drum type washing machine 10 may have, for example, a heat pump or heater type drying function.

no. 2 approach

[0031] Figure 4 A front-loading washing machine according to the second embodiment is shown in .

[0032] exist Figure 4 In the shown second embodiment, the treatment agent tank 20 is arranged on the right side in the front view of the outer case 11 . That is, the processing agent tank 20 is provided on the side opposite to the processing agent cartridge 15 located on the left side in the front view of the outer case 11 . By arranging the processing agent tank 20 on the side opposite to the processing agent cartridge 15 , the processing agent tank 20 is separated from the water supply valve unit 18 . Therefore, the overall length of the water supply path part 31 becomes large by the processing agent tank 20, and a structure becomes complicated. On the other hand, by arranging the processing agent tank 20 on the side opposite to the processing agent cartridge 15 , it is possible to avoid interference between the processing agent tank 20 and the processing agent cartridge 1...

no. 3 approach

[0036] Figure 5 A front-loading washing machine according to the third embodiment is shown in .

[0037] exist Figure 5 In the illustrated third embodiment, the treatment agent tank 20 is provided adjacent to the water supply valve unit 18 . That is, the processing agent tank 20 is provided behind the outer case 11 . Furthermore, in 3rd Embodiment, the detergent chamber 21 and the softener chamber 22 which are two storage chambers of the processing agent tank 20 are arranged side by side in the left-right direction. As mentioned above, the door 12 side of washing tub 13, that is, the front is inclined upward. Therefore, the space formed between outer case 11 and washing tub 13 is larger in the rear than in the front. Therefore, by arranging the processing agent tank 20 at the rear where the space is relatively large, it is easy to secure the capacity of the processing agent tank 20 without enlarging the outer case 11 . And the cleaning agent chamber 21 and the softener ...

Abstract

A drum type washing machine comprises a washing drum, an outer box and a treating agent tank. The washing drum accommodates the rotating drum. The outer box is arranged on the outer sides of the rotary drum and the washing drum. The treatment agent tank is provided in a space formed above the washing drum between the washing drum and the outer box, and two or more storage chambers in which two ormore different types of automatically fed washing treatment agents are stored for each type of washing treatment agent are arranged in the front-rear direction of the outer box.

Description

technical field [0001] This embodiment relates to a drum type washing machine. Background technique [0002] Conventionally, there is known a washing machine that automatically injects a washing treatment agent such as a detergent or a softener. Such a washing machine is equipped with a processing agent box for manually injecting a cleaning agent by a user as in the past, in addition to a function of automatically injecting the cleaning agent. In the case of Patent Document 1, the washing machine is provided above the main body with a treatment agent cartridge arranged at the front and a water supply valve unit arranged at the rear. Furthermore, a processing agent tank (tank) which stores the automatically injected cleaning processing agent is arrange|positioned between the said front processing agent box, and a rear water supply valve part. With the advancement of automation of washing machines, the capacity of the treatment agent tank is required to increase. [0003] H...
