In the prior art, whether damage for the refrigerator frost removal timer and generally can only wait for after whether frost removal timer goes wrong in the course of work of reality and could find, like this, be unfavorable for the use and the refrigerator maintenance of frost removal timer; Be difficult to especially before dispatching from the factory, detect for the frost removal timer that newly dispatches from the factory, be unfavorable for the lifting of frost removal timer product export yield rate.
The utility model content
Whether the utility model is in the deficiency that normal operating conditions detects existence in order to solve the current refrigerator frost removal timer, and a kind of refrigerator frost removal timer proving installation is provided.
The technical matters of the required solution of the utility model, can realize through following technical scheme:
A kind of refrigerator frost removal timer proving installation is characterized in that, comprising:
First housing is provided with the refrigerator mimic channel in first housing;
Be arranged on the frost removal timer reed patchhole of first surface of shell, reed links to each other with refrigerator mimic channel corresponding simulating circuit after inserting patchhole;
The pilot lamp of display refrigerator mimic channel duty.
In the utility model, said reed patchhole comprises two input contact jacks and two output inserted sheet jacks, to hold four reeds of frost removal timer.
In the utility model, said working station indicator is arranged on surface of shell, comprises defroster status indicator lamp, frost removal timer motor power pilot lamp and refrigerator refrigerating state pilot lamp.
In the utility model, said working station indicator is located on first housing top and second housing that first housing is connected.
Said first housing and second housing have common bonnet, to protect first housing and second housing.
The refrigerator frost removal timer proving installation of the utility model; Through adopting the refrigerator mimic channel duty of refrigerator is simulated; Can whether normally test the frost removal timer duty effectively; On the one hand need not after frost removal timer goes wrong, just to change the deficiency that the frost removal timer of also having avoided simultaneously newly dispatching from the factory is difficult to detect.
In addition, the setting of the frost removal timer proving installation through two kinds of different structures can be satisfied respectively and go out to test portable demand, and the demand of inside plants test, has improved the scope of application of the utility model greatly.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of first kind of embodiment of the utility model.
Fig. 2 is the structural representation of second kind of embodiment of the utility model.
Embodiment
For the technological means, the creation characteristic that make the utility model, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the utility model.
The purport of the utility model is whether the current refrigerator frost removal timer is in the deficiency that normal operating conditions detects existence, a kind of device that can test the refrigerator frost removal timer easily is provided, to increase work efficiency.
Referring to Fig. 1; First kind of embodiment of the utility model, refrigerator frost removal timer proving installation comprise that first housing, 1, the first housing 1 is the basis of whole testing device; The utility model is provided with refrigerator mimic channel (not signal) in first housing 1; The refrigerator mimic channel will be simulated the actual working state of refrigerator, be used for cooperating the test frost removal timer, because those skilled in the art knows the principle of work of refrigerator; For how the refrigerator mimic channel is set also know, no longer tire out here and state.
Existing frost removal timer is provided with 4 reeds usually, and short reed links to each other with power supply, other three reeds respectively with the compressor circuit, and heater line link to each other; Its short-and-medium reed is a fixed touching plate, and other three reeds are movable contact spring, under the motor effect of frost removal timer, start compressor or well heater respectively, makes refrigerator be in refrigeration or defrost state.
For ease frost removal timer is tested; The utility model is provided with frost removal timer reed patchhole at the outside surface of first housing 1; Patchhole 2 holds the short reed of frost removal timer, and patchhole 3 holds the reed that is connected with the compressor circuit, and patchhole 4 holds the reed that is connected with ground; Patchhole 5 holds the reed that is connected with heater line, and reed links to each other with refrigerator mimic channel corresponding simulating circuit after inserting patchhole.
Under a kind of more excellent embodiment, the short reed of frost removal timer does not contact with the cam of frost removal timer, and an end of patchhole 3, patchhole 4 and each self-corresponding reed of patchhole is conflicted in the side of cam.During the cam rotation, patchhole 3 pairing reeds are in the recess of cam, and patchhole 4 pairing reeds can drop in recess in certain angle, thereby patchhole 3 contacts with patchhole 4 pairing two reeds, compressor start, and well heater breaks off; When cam continued rotation, patchhole 4 pairing reeds can break away from recess, and like this, patchhole 3 no longer contacts with patchhole 4 pairing two reeds, and patchhole 4 contacts with patchhole 5 pairing two reeds, and compressor stops, and well heater begins the defrosting action.
Like this; When frost removal timer was in the different operating state, the refrigerator emulation mode pilot lamp on first housing, 1 surface correspondingly lighted, and explains that frost removal timer is in proper working order; Otherwise there is fault in frost removal timer; Need to repair or change,, can check the duty of frost removal timer easily through the proving installation of the utility model.In the present embodiment, pilot lamp 6, pilot lamp 7 and pilot lamp 8 are respectively defroster status indicator lamp, frost removal timer motor power pilot lamp and refrigerator refrigerating state pilot lamp.
The refrigerator frost removal timer proving installation of present embodiment, profile is smaller and more exquisite, can carry, and therefore is highly suitable under the operating mode of going out frost removal timer is tested.
Referring to Fig. 2, second kind of embodiment of the utility model, identical with first kind of embodiment is that the refrigerator mimic channel is arranged in first housing 11, the reed patchhole 21 of frost removal timer is arranged on first housing, 11 surfaces; What they were different with first kind of embodiment is; The pilot lamp 31 of refrigerator mimic channel duty is arranged on first housing, 11 tops and second housing 41 that first housing 11 is connected; Simultaneously; First housing 11 and second housing 41 also have common bonnet 51, to protect first housing 11 and second housing 41.Because the principle of work of second kind of embodiment frost removal timer proving installation is identical with first kind of embodiment, no longer tires out and states here.
The refrigerator frost removal timer proving installation of present embodiment is compared with first kind of enforcement, and structure is more firm, under the situation that does not need frequent mobile test device, is more suitable in inside plants frost removal timer being tested.
Below only be described, but can not be interpreted as it is restriction claim with regard to the utility model preferred embodiment.The utility model not only is confined to above embodiment, and its concrete structure allows variation.In a word, all various variations of in the protection domain of the utility model independent claims, being done are all in the protection domain at the utility model.
