Abstract

The utility model relates to a timer for a clothes dryer. The timer comprises a pedestal, a cover cap, a micro motor, transmission gear sets, core shafts, a time cam, and a contact reed set. The micro motor is mounted outside the pedestal and drives the time cam to rotate counter clockwise with the transmission gear sets. The contact reed set abutted against the time cam is connected and disconnected according to designed time segments. The contact reed set is connected with the cold air function part and heating function part of the clothes dryer. The transmission gear sets are sleeved on the core shafts. One end of the micro motor is connected with a safety capacitor, while the other end of the micro motor is connected with the contact reed set.

Description

The dryer timer

Technical field

The utility model relates to a kind of accessory of household electrical appliance, specifically is a kind of timer that is applied to dryer.

Background technology

Since drying function rapid draing clothing, and have sterilizing function, and particularly Bei Fang winter, the difficult situation about doing of winter coat needs especially.At present, dryer is controlled function and the timing of dryer mostly on the market with cyclelog, and the cyclelog volume is bigger, and the drive motors volume is also bigger, the assembly technology complexity, and cost is higher.

The utility model content

Technical problem to be solved in the utility model is, provides a kind of and simple in structure can control the various functions of dryer, as the timer of cold wind, heating, timing function.

The utility model is achieved through the following technical solutions:

The dryer timer comprises pedestal, cover cap, micromachine, driving gear set, mandrel, time cam, contact spring group; Described micromachine is installed in outside the pedestal, drives the time cam by driving gear set and is rotated counterclockwise, and the contact spring group that is resisted against on the time cam switched on and off by the designed time period, and the contact spring group connects dryer cold wind, heating function; Described gear train is sleeved on the mandrel; Described micromachine one end is connected with safety electric capacity, and the other end is connected with the contact spring group.

Described miniature motor rotor top is provided with the check sheet that makes the rotor orientation rotation.

Described contact spring group is resisted against on the time cam contour surface.

After adopting above structure, the utility model compared with prior art has the following advantages:

1, the more compact structure overall volume is littler, can save the space;

2, micromachine is installed in outside the pedestal, and structure is simpler, has improved efficiency of assembling.

Embodiment

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing, in the example of described embodiment from start to finish identical or similar label represent identical or similar parts or the parts with identical or similar functions.The embodiment that describes below is exemplary, only is used for explaining this patent, and can not be interpreted as the restriction to this patent.

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

The dryer timer comprises pedestal 2, cover cap 1, micromachine 3, driving gear set 5, mandrel 6, time cam 7, contact spring group; Described micromachine is installed in outside the pedestal, drives the time cam by driving gear set and is rotated counterclockwise, and the contact spring group that is resisted against on the time cam switched on and off by the designed time period, and the contact spring group connects dryer cold wind, heating function; Described driving gear set 5 is sleeved on the mandrel 6; Described micromachine 3 one ends are connected with safety electric capacity 13, and the other end is connected with the contact spring group.

Described contact spring group includes 1

# terminal

9,2

# terminal

10,3

# terminal

11,5# terminal 12.

Described micromachine 3 is installed in outside the pedestal 2, micromachine turns clockwise by check sheet 4 orientations, again by gear train 5 deceleration transmission, great wheel assembly shifting block 82 drives time cam 7 and is rotated counterclockwise, and the 1# terminal 9 that is resisted against on the time cam switches on and off by the time period that sets and 2

# terminal

10,3# terminal 11.

Described gear train 5 is sleeved on the mandrel 6.

Described 1# terminal 9 connects blower fan and micromachine 3.

Described 2# terminal 10 connects input power supply phase line.

Described 3# terminal 11 connects heater.

Described 5# terminal 12 connects zero-power line and safety electric capacity 13.

Described safety electric capacity 13 other ends connect micromachine 3.

Described time cam 7 has the circular arc of different radii to be connected.

When pressing needed timing, main shaft 81 backs (in 200 °) turn clockwise, great wheel assembly 8 drives time cam 7 by shifting block 82 and turns clockwise, be resisted against 1

# terminal

9 and 2# terminal 10 on time cam 7 appearance profiles, 3# terminal 11 is connected, power supply is by 2

# terminal

10,5# terminal 12, safety electric capacity 13, micromachine 3 forms the loop, micromachine 3 starts the back rotation, after check sheet 4 orientations, micromachine 3 is rotation in the direction of the clock all the time, through gear train 5 deceleration transmission, drive great wheel assembly 8 and time cam 7 and be rotated counterclockwise, be the utility model hot blast sterilization definition status this moment, as shown in Figure 3.

When time cam 7 is rotated counterclockwise to Fig. 4 position, the 1# terminal 9 that is resisted against on the time cam outline is subjected to the effect of contact spring pressure with 2# terminal 10, fall into time cam small-radius arc, 3# terminal 11 with disconnect with 2# terminal 10, the heater that is connected with 3# terminal 11 quits work, and forward cold wind definition status by the hot blast sterilization this moment.

When time cam 7 continued to rotate to Fig. 5 position counterclockwise, the blower fan and the timer micromachine 3 that are connected with 1# terminal 9 quit work simultaneously, halted state when be the utility model hot blast fungicidin this moment.

When at the thinner clothing of drying, need not heat when only needing blower fan work, then be rotated counterclockwise in main shaft 81(80 °, cam 7 is rotated counterclockwise to Fig. 6 position) the setting required time, 1

# terminal

9 and 2# terminal 10 are connected, and be the utility model cold wind definition status this moment, as shown in Figure 6.

When cam 7 was rotated counterclockwise to Fig. 7 position, cold wind regularly finished, and dryer quits work.

From the above, as long as clockwise or be rotated counterclockwise main shaft 81 in different angles, in the time of just conveniently finishing the hot blast fungicidin of dryer, cold wind regularly, the function of shutting down.

The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection range of this patent.
