Abstract

The utility model discloses a separated controlling switch for an electrothermal pot, which belongs to an auxiliary device of a kitchen household appliance and comprises a casing, switches, a leading wire and a power supply plug. The separated controlling switch for an electrothermal pot is characterized in that the casing 1 is provided with more than one switch; an electricity leakage indication lamp 6, controlled silicon 10 and a connection terminal 11 are arranged in the casing. Because the separated controlling switch for an electrothermal pot is separated from a pot body, the separated controlling switch for an electrothermal pot has the functions that the separated controlling switch for an electrothermal pot can prevent electricity from leaking caused by splashing water and prevent the switches from deforming in a high temperature, etc. Besides, the separated controlling switch for an electrothermal pot has the advantages of electricity leakage indication, super high temperature control, heat insulation, etc.

Description

Separated controlling switch for electrothermal pot

Electric food warmer separate type control switch of the present utility model, the attached device that helps of genus kitchen household electrical appliance.

The electric food warmer of selling on the domestic market is varied at present, but control switch generally all will be installed on the pedestal of pot body, it has easy for installation, advantages such as compact conformation, but, therefore exist unsafe factor because cooker be unable to do without water, electric shock accidents takes place easily, and being close to the temperature of boiler height, the life-span is short, poor reliability etc.

In order to solve the problem of above-mentioned existence, the purpose of this utility model just is to provide a kind of safe and reliable, separate type control switch that the life-span is long.

The purpose of this utility model realizes in the following way: whole switch comprises housing, switch, lead-in wire and attaching plug, it is characterized in that: be provided with more than one switch on housing 1, electric leakage indicator light 6, controllable silicon 10, binding post 11 are installed in the housing.

The purpose of this utility model also can realize in the following way:

Concavity can be made in described housing 1 two ends, also can make tabular, other shape such as circular-arc.

Described attaching plug 8, pot body socket 7 can be arranged on same end, also can be arranged on two ends.

Set more than one switch is provided with three switches for best.

A described above switch can be connected in series a thermostat at its input.

Hanger 2 also can be set up in the upper end of described base plate 9.

To be the utility model electric food warmer look schematic diagram with the master of separate type control switch to Fig. 1;

Fig. 2 is the side view cutaway drawing of the utility model electric food warmer with the separate type control switch;

Fig. 3 is the schematic circuit of the utility model electric food warmer with the separate type control switch;

Fig. 1-the 3rd, most preferred embodiment of the present utility model, the utility model is described in further detail below in conjunction with accompanying drawing:

Among Fig. 1-3: 7 pots of body sockets of 1 shell 2 hanger 3-5 switches, 6 electric leakage indicator lights, 8 attaching plugs, 9 base plates, 10 controllable silicons, 11 binding posts.

If when establishing a switch, can link to each other with an electric heating element such as an electric heating tube more than the 800W.

If establish two switches, can set up a preservation and controlling key, also can not establish the preservation and controlling key, two switches link to each other with two electric heating tubes or other electrical heating elements respectively.

Most preferred embodiment of the present utility model is that three switch 3-5 are set, they are 3 years old, 4 respectively with two electric heating tube 800W, 400W is connected to form power control switching, switch 5 one ends and switch 3,4 parallel connections, the other end links to each other with the 400W electric heating tube by one-way SCR 10, utilize single-phase silicon-controlled pressure regulation, control 400W electrothermal tube, make power output about 40W, can provide 800W by permutation and combination, 400W, 1200W, 40W four retainings and adjustable continuously, switch 5 is the preservation and controlling key, in order to limit the temperature of whole electric food warmer, at thermostat of switch 3-5 input series connection, electric leakage indicator light 6 be attempted by on the ground wire after fuse is connected, when supply socket does not have ground wire or contacts bad and pot body when electric leakage is arranged, indicator light is lighted, and reminds people is noted, waits electric leakage to get rid of and re-uses.

Electric food warmer separate type control switch of the present utility model use is as follows: as shown in Figure 1, during use attaching plug 8 is inserted supply socket, pot body socket 7 inserts on the binding post of pot body, the 800W electrothermal tube send when by switch 3, the 400W switch send during by switch 4, after two switches are pressed simultaneously, power output is 1200W, when stewing rice need be incubated, 3,4 switches that can stop are pressed switch 5 and are utilized controllable silicon 5 pressure regulation, make power output about 40W, can reach like this and can be incubated, rice-caking-proof again function.

Electric food warmer Separated controlling switch of the present utility model compared with prior art has following advantage:

1, separate with the pot body, anti-sealing splashes switch and causes that leaky takes place, and has improved the security that people use electric heating appliance.

2, away from the pot body, prevent that the temperature of boiler height is to the impact of switch life and reliability in the process of cooking.

3, design hanger and housing design concavity can conveniently wind the line and hang on the wall.

4, the electric leakage indicator lamp is set, prevents from the human casualty accident that causes because of electric leakage from having improved safety, reliability.
