Detailed Description

In order to better understand the purpose, structure and function of the present invention, a switch combination module and a household appliance of the present invention are further described in detail below with reference to the accompanying drawings.

The household appliance comprises the switch combination module, and a plurality of electric devices in the machine body are synchronously electrified or powered off through the switch combination module.

As shown in fig. 1 and 2, the switch combination module includes a switch bracket 1, a switch pressing block 2, and a microswitch 3. The switch pressing block 2 is rotatably connected to the switch bracket 1. At least one microswitch 3 is arranged around the switch pressing block 2 and fixed on the switch bracket 1. The switch pressing block 2 is provided with a flange 21 on the side surface, the micro switch 3 is provided with contacts 31, and the flange 21 corresponds to the contacts 31 one by one. By the rotation of the switch block 2, the flange 21 presses the contact 31, thereby controlling the opening and closing of the microswitch 3. And each microswitch 3 is connected to a respective electrical device.

Therefore, when all the contacts 31 are pressed into the micro switch 3 by the flange 21 at the same time, the micro switch 3 energizes the corresponding electric devices, and the switch combination module synchronously starts all the electric devices; when the contacts 31 are misaligned with the flange 21, the contacts 31 automatically rebound and the micro switch 3 opens the corresponding electrical device. This makes it possible to simultaneously control the switching of a plurality of electrical components by one switching assembly. According to the arrangement relationship of the micro switches 3 and the flanges 21, only one group of micro switches 3 can be turned on according to the requirement, so that the flanges 21 are required to be grouped, and the flanges 21 of the same group are simultaneously contacted with the contact 31 of the micro switches 3.

In order to realize the rotating connection of the switch pressing block 2 and the switch support 1, the switch support 1 is fixedly connected with a rotating shaft 4, a sleeve hole is formed in the bottom surface of the switch pressing block 2, the sleeve hole is sleeved on the rotating shaft 4, and therefore the switch pressing block 2 rotates around the rotating shaft 4.

In order to prevent the switch pressing block 2 from falling off from the rotating shaft 4, the switch bracket 1 is fixedly connected with a buckle 5 beside the rotating shaft 4. The switch pressing block 2 is provided with a clamping groove 22, the clamping groove 22 is arc-shaped, and the buckle 5 is clamped with the clamping groove 22. When the switch pressing block 2 rotates, the clamping groove 22 moves relative to the buckle 5, and the clamping groove 22 also plays a certain limiting role.

In order to facilitate the reset of the switch pressing block 2, the switch combination module comprises an elastic piece. The switch pressing block 2 and the switch support 1 are provided with hooks. Thus, two ends of the spring 6 as an elastic part are respectively hung on the hanging buckles of the switch pressing block 2 and the switch bracket 1. Thus, the elastic member drives the switch pressing block 2 to reset.

In order to prevent the spring 6 from falling, the switch support 1 is fixedly connected with a reset stop dog 7, and the switch pressing block 2 is abutted against the reset stop dog 7 after being rotated under the action of the tensile force of the spring 6, so that the reset position is consistent after repeated opening and closing.

In order to rotate the switch pressing block 2, a pressing rod 23 is fixedly connected to the side surface of the switch pressing block 2, so that the switch pressing block 2 can be rotated conveniently.

The working process is as follows, the switch pressing block 2 is rotated through the pressing rod 23, so that part or all of the flanges 21 are contacted with the corresponding contact 31 of the micro switch 3, and the opening and the closing of the electric devices of different groups are synchronously controlled.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes in the features and embodiments, or equivalent substitutions may be made therein by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
