Embodiment Construction

[0016] see Figure 1 to Figure 7 , The electromechanical timer of the present invention includes a box body 1, a handle 2, and a motor 3 and a transmission device 4 installed in the box body 1. The box body 1 is composed of a lower case 11 and an upper cover 12 , the upper cover 12 covers the lower case 11 and forms a receiving chamber 13 with the lower case 11 . The motor 3 is fixed in the housing chamber 13 and has a motor shaft 31 . The transmission device 4 includes a first gear 41, a second gear 42, a worm wheel 43 and a worm 44, the first gear 41 is smaller than the second gear 42, and the first gear 41 is coaxially sleeved on the motor shaft 31 of the motor . The second gear 42 meshes with the first gear 41 . The worm 44 is integrated and coaxial with the second gear 42 . The worm gear 43 is annular, and has external teeth 45 and internal teeth 46. The external teeth 45 are distributed on the same circumference and mesh with the worm 44. There are thirty-two interna...

Abstract

The disclosed electromechanical timer comprises: a box with a motor and an one-way gear device; the gear device connected with the motor shaft and a ratchet structure, a handle fixed on the ratchet structure, and a voltage acquisition unit with output end connected with the control unit. This invention can implement timing at any position.

Description

technical field [0001] The invention relates to the field of timers, in particular to a timer used in household appliances. Background technique [0002] Existing household washing machines are generally provided with a rotary switch, and the user realizes the timing function by rotating the "rotary switch". However, the existing rotary switch has the following disadvantages: high cost, poor intelligence: timing at any position cannot be realized, and it cannot be quickly and automatically rotated to the 'off' position, and the timing of each position is not variable, and the number of timing positions is small. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an electromechanical timer capable of realizing arbitrary timing. [0004] The technical solution adopted by the present invention to solve the technical problem is: the electromechanical timer includes a box b...
