Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brush-type dishwasher that cleans dishes using a cleaning brush.

Conventional brush-type dishwashers have a rotating cleaning brush installed at the bottom of the center of the inner tank, and the dishes are washed by sliding the dishes into contact with this cleaning brush. There was a risk that the soap solution and foam adhering to the cleaning brush would scatter as it rotated, contaminating the surrounding area. Also, if you wash dishes by pressing them against the rotating cleaning brush, the dishes will also rotate at the same time as the cleaning brush, and your hands may become slippery due to the detergent, causing the dishes to often slip. They were breaking dishes. When the cleaning brush is rotated using a motor as a driving source, a speed reduction mechanism is required, and the speed must be normally reduced to 1/15 to 1/20. When the reduction ratio is high as described above, it is necessary to use a reduction mechanism such as a two-stage gear reduction or a worm gear reduction, and in this case, the structure is complicated, resulting in high costs.

The present invention has been made to solve the above-mentioned conventional problems, and one embodiment thereof will be described below with reference to the accompanying drawings. In the figure, reference numeral 1 denotes an outer and inner tank of a dishwasher, and a cleaning brush 2 that vibrates in the horizontal direction is disposed at the center of the bottom of the inner tank 1. A knob 3 is provided on the upper edge of the inner tank 1, and by operating this knob 3, the cleaning brush 2 can be operated and stopped. 4 is a display board that displays the operation section. In addition, a rubber stopper 5 is closed at the bottom of the inner tank 1.
It can be filled with water. 6 is a lid that covers the upper opening of the inner tank 1. Further, the cleaning brush 2 is inserted into a connecting boss 9, and the connecting boss 9 is screwed into a central brush holding portion 8 of a support member 7 that is supported so as to be movable in the horizontal direction. Furthermore, the outer wall of the connecting boss 9 is formed into a spline shape so that the cleaning brush 2 can be easily attached and detached. Also, a bearing part 1 in which a metal 10 is inserted and fitted on the central axis concentric with the central brush holding part 8.
1, and its outer peripheral portion 12 and the outer peripheral flange portion 13 of the supporting member 7 located below are connected by several connecting rods 14. Further, this outer peripheral flange portion 13 is fixedly fixed together with a motor hinge 16 by screws to a mounting boss 15 protruding from the bottom rear surface of the inner tank 1. The outer peripheral flange portion 13, the connecting rod 14, the bearing portion 12 of the central swinging portion, and the brush holding portion 8 of the support member 7 are each integrally molded from resin to reduce assembly man-hours. The fixed outer peripheral flange portion 13 and the central swinging portion are supported flexibly so as to be swingable. Furthermore, an eccentric shaft 18 connects the shaft 17a of the motor 17 and the central swinging portion of the support member 7 to vibrate.
A tip 19 of the eccentric shaft 18 is rotatably fitted into a metal 10 inserted into the bearing section 12. Also, the recess 19a at the tip 19 of the eccentric shaft 18
A ball 20 is inserted into the cleaning brush 2.
supports the thrust load applied to the The eccentric shaft 18 is also fixed to the shaft 17a of the motor 17, and as the motor 17 rotates, the tip 19 of the eccentric shaft 18 rotates eccentrically. That is, since the central swinging portion of the support member 7 makes a circular vibration about the motor shaft 17a, the cleaning brush 2 also makes a similar circular vibration. Since the entire dishwasher also vibrates due to this circular vibration, a weight 21 is provided on a part of the eccentric shaft 18 for balance. Reference numeral 22 denotes a waterproof shock absorber made of rubber or the like provided between the central brush holding portion 8 of the support member 7 and the inner tank 1. This prevents vibrations from entering the body and from transmitting vibrations. A cover 23 is formed integrally with the connecting boss 9 so as to cover the upper part of the buffer body 22;
4 is a drain pipe communicating with the bottom hole 1a of the inner tank 1, and 25 is a changeover switch having an operation button 3 for operating and stopping the cleaning brush.

The operation of the cleaning brush in the above configuration will be explained. Further, when the motor 17 rotates, the tip 19 of the eccentric shaft 18 fixed to the motor shaft 17a rotates eccentrically. Due to this eccentric rotation, the central swinging portion of the support member 7 makes circular vibrations about the motor shaft 17a. The cleaning brush 2 attached to the central brush holding portion 8 of the support member 7 via the connecting boss 9 also makes a similar circular vibration, and the dishes are washed by applying the dishes to the cleaning brush 2.

As is clear from the above embodiments, according to the present invention, the cleaning brush disposed in the inner tank is vibrated in the horizontal direction, so that the soap solution foams unlike the conventional rotating cleaning brush. There is no longer any problem of the dishes being scattered, and since the cleaning brush itself vibrates, there is no force to move the dishes around when you place the dishes to be washed against the cleaning brush, so the cleaning process is relatively simple. It's easy to do, and there's less chance of breaking dishes. Moreover, in the present invention, the mechanism for horizontally vibrating the cleaning brush holds the cleaning brush,
Moreover, it is composed of a support member supported so as to be swingable in the horizontal direction, an eccentric shaft that rotatably fits into the central swinging part of this support member, and a motor that rotates this eccentric shaft. This eliminates the need for a speed reduction mechanism such as the one shown in FIG.
