Description

Technical Field

[0001] The utility model relates to the technical field of timers, in particular to an electric timer with a compact structure. Background Art

[0002] With the progress of the times and the development of society, washing machines with soaking function have occupied a large market share in the market. The advantages of this washing machine are obvious: with soaking function, the detergent can be fully dissolved, the washing degree is high, and the cleaning degree is good. In order to make the washing machine have the soaking washing function, first of all, the timer used must have the soaking washing function. Among the two existing soaking washing timers, the single-axis soaking washing timer cannot be used on the washing machine that originally used the double-axis timer due to the installation structure and other reasons. The electric double-axis soaking washing timer can be installed on such washing machines (and this washing machine has been produced so far), but due to the high cost of the electric double-axis soaking washing timer, it is not economical to use this timer from the cost point of view. Therefore, the market calls for a low-priced and stable quality soaking washing timer, such as a mechanical double-axis soaking washing timer. Due to the characteristics of soaking washing, the total time of the washing process needs to be divided into several sections. Generally, the total time is designed to be about 35 minutes or more and then divided into sections. This requires that the speed change system of the timer wheel system must be satisfied first, and some components must be added to make the total washing time divided into sections.

[0003] The timer with soaking function currently available on the market generally has the following structure: it comprises a housing, in which an escapement structure with a stable movement cycle is arranged, the escapement mechanism comprises an escapement pendulum, a timing spindle is passed through the bottom of the housing, a buzzer cam, a soaking cam, a main cam and a head wheel are sequentially mounted on the timing spindle from top to bottom, and the escapement pendulum and the head wheel are connected together through a speed change gear system; a buzzer reed, a driven reed and a driving reed are sequentially arranged at intervals on one side of the timing spindle in the housing, a spring sheet is further arranged below the buzzer reed, the driven reed and the driving reed, and a shaft is arranged at the bottom of the housing, on which a buzzer reed, a driven reed and a driving reed are rotatably mounted in sequence from top to bottom. lever, immersion lever and main control lever; one end of the buzzer lever is always in contact with the working surface of the buzzer cam, and the other end has a resistance portion extending downward and extending between the buzzer reed and the driven reed and always in contact with the buzzer reed; one end of the immersion lever is always in contact with the working surface of the immersion cam, and the other end is always in contact with the active reed, one end of the main control lever is always in contact with the working surface of the main cam, and the other end of the main control lever is always in contact with the spring sheet, and a limiting structure is provided between the main control lever and the escapement pendulum; the buzzer reed, driven reed, active reed, spring sheet, immersion cam, main cam, immersion lever and main control lever are all located above the escapement pendulum.

[0004] Since the timer with the soaking function is improved on the original timer without the soaking function, the soaking cam, soaking lever, spring sheet and other components are added. The components above the escapement pendulum of the original timer are relatively numerous, and the space left above the escapement pendulum is also very limited. The buzzer reed, driven reed, active reed, spring sheet, soaking cam, main cam, soaking lever, and main control lever are all located above the escapement pendulum. This leads to the need to increase the size of the timer shell in order to add these additional components. Since the timer shell is made of plastic, increasing the size not only increases the cost, but more importantly, it will increase the overall deformation, that is, the stability of the shell size and shape is not good. Because according to experience, if the size is increased, the quality stability of the timer will be difficult to guarantee; another important constraint is that the installation space and size of the existing washing machine for the timer are fixed. It can be foreseen that if the size of the timer is increased without reason or the standardized installation and positioning size is changed, then it is bound to face the embarrassing situation that the washing machine must be redesigned or remodeled in order to use the timer, which is something most washing machine manufacturers are unwilling to do, and the vitality of the timer will be greatly reduced.

[0041] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0042] like Figure 1-6 As shown, the following embodiment discloses a compact electric timer.

[0043] A compact electric timer, comprising:

[0044] Housing 100;

[0045] Gear set 200;

[0046] The timing main shaft 300 is disposed on the housing and transmits the gear set 200;

[0047] The soaking wheel assembly 400 is used to drive the reed in the soaking mode to make the soaking reed a and the static reed b contact or disconnect;

[0048] It also includes a buzzer reed d, which is driven by the soaking wheel set 400 to make the buzzer reed d contact or disconnect with the moving reed c.

[0049] The above is the basic solution of this embodiment.

[0050] Reference Figure 1 and Figure 2 As shown, the timing main shaft 300 is driven to rotate by the motor, driving the gear set 200 for transmission, and the soaking wheel set 400 is provided with a transmission gear 410 which is connected to the gear set 200 for transmission; when the soaking wheel set 400 rotates, the reed of the soaking mode is driven, so that the washing machine has two states, the soaking mode and the non-soaking mode; at the same time, the soaking wheel set 400 drives the buzzer reed d, so that the buzzer reed d is connected or disconnected, and when the buzzer reed d and the moving reed c are connected, the washing machine buzzes, and the washing process is ended.

[0051] In this embodiment, the reversing mechanism 500 is connected via the gear set 200 , and its connection mode and driving mode are consistent with those in the prior art, which will not be described in detail here.

[0052] In the configuration of this embodiment, the buzzer reed d is driven by the soaking wheel set 400, thereby reducing the driving structure of the buzzer reed d, streamlining the components of the timer, and reducing the external dimensions of the timer.

[0053] Preferably, in this embodiment, a driving portion 421 is provided on the soaking wheel assembly 400, and the driving portion 421 contacts the first lever end 610 to drive the driving lever 600 end in reverse.

[0054] In this embodiment, the soaking wheel group 400 is set to rotate clockwise, and the driving part 421 rotates in the same direction and speed as the soaking wheel group 400. When the driving part 421 rotates, the first lever end 610 of the driving lever 600 is driven, thereby causing the second lever end 620 to rotate and drive the buzzer reed d.

[0055] Preferably, in this embodiment, the driving lever 600 is rotatably connected to the inside of the housing 100 and is configured as a V-shaped lever.

[0056] Preferably, in this embodiment, the driving portion 421 is disposed on the power-on cam 420 and protrudes from the end surface of the power-on cam 420 .

[0057] Specific reference Figure 3 As shown, in this embodiment, the specific implementation of the driving part 421 is: the driving part 421 is an arc-shaped convex portion arranged on the soaking wheel group 400, the concave surface of the arc-shaped convex portion facing the center of the power-on cam 420 is the driving surface 421.1, and the first lever end 610 is provided with a column in contact with the driving surface 421.1.

[0058] In this embodiment, the first lever end 610 and the second lever end 620 are both convex parts arranged at the two ends of the driving lever 600, and the convex parts are tangent to the arc-shaped driving surface 421.1 on the driving part 421;

[0059] When the driving portion 421 rotates with the energized cam 420 , the arcuate driving surface 421 . 1 applies an inclined driving force to the outer periphery of the first lever end 610 , thereby causing the first lever end 610 to rotate around the central axis of the driving lever 600 .

[0060] Preferably, the two ends of the driving surface 421.1 are sequentially arranged as a near driving end and a far driving end along the rotation direction of the soaking wheel assembly 400;

[0061] The distance between the distal driving end and the central axis of the soaking wheel assembly 400 is greater than the distance between the proximal driving end and the central axis of the soaking wheel assembly 400.

[0062] Specific reference Figure 4 and Figure 5 As shown, when the powered cam 420 rotates clockwise, it first contacts the distal driving end, which drives the first lever end 610. As the powered cam 420 continues to rotate, the distance between the portion of the driving surface 421.1 that contacts the first lever end 610 and the central axis of the soaking wheel assembly 400 gradually decreases. Therefore, the first lever end 610 is pulled toward the central axis of the soaking wheel assembly 400, so that the driving lever 600 rotates clockwise. Therefore, the second lever end 620 pushes the buzzer reed d outward to make it contact with the moving reed c.

[0063] In this embodiment, in order to simplify the timer, the moving reed c, the stationary reed b and the soaking reed a are arranged in sequence in a direction away from the soaking wheel group 400, and a lever group 700 is provided for driving.

[0064] Reference Figure 2 As shown, the soaked reed a, the static reed b and the dynamic reed c are arranged side by side from the outside to the inside.

[0065] In order to satisfy that the moving reed c can contact both the buzzing reed d and the static reed b, in this embodiment, the moving reed c is a long reed with a buzzing contact in the middle and an electrical contact at the end.

[0066] Specific reference Figure 2 As shown, the lever group 700 is arranged at the end, and can drive the electrical contact part of the moving reed c. The driving lever 600 is arranged on the side of the moving reed c and is located near the buzzer contact, and is used to drive the buzzer reed d and the buzzer contact on the moving reed c.

[0067] Specific reference Figure 6 As shown, in this embodiment, the specific implementation of the lever group 700 is as follows: the lever group 700 includes a soaking lever 720 and a power-on lever 710 which are coaxially arranged, and the soaking lever 720 pulls the soaking reed a toward the static reed b to make it contact with the static reed b;

[0068] The energizing lever 710 pushes the moving reed c toward the stationary reed b so as to make it contact with the stationary reed b.

[0069] Both ends of the lever are arranged as protruding parts, which can drive the reed.

[0070] The soaking wheel assembly 400 includes a soaking cam 430 and a power-on cam 420, which respectively drive a soaking lever 720 and a power-on lever 710.

[0071] Reference Figure 6 As shown, a push rod is provided on the soaking lever 720, and the push rod is located between the soaking reed a and the static reed b, and is used to push the soaking reed a away from the static reed b;

[0072] The power-on lever 710 is located between the moving reed c and the power-on cam 420, and is used to push the moving reed c to the side of the stationary reed b to contact the stationary reed b and conduct electricity;

[0073] At the same time, the end of the stationary spring piece b is fixed to the housing 100.

[0074] In this embodiment, the way in which the soaking wheel group 400 drives the reed through the lever group 700 is consistent with the driving method in the prior art, and will not be described in detail here.

[0075] In addition, in this embodiment, the static reed b, the dynamic reed c, the soaking reed a and the buzzing reed d are all arranged on the inner side of the housing 100, and the tails extend out of the housing 100 to connect with the wires.

[0076] In this configuration, no wires are arranged inside the housing 100, and the tails of the reeds are extended to the outside of the housing 100 for power supply, thereby ensuring the simplicity of the components inside the housing 100.

[0077] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
