Abstract
The utility model discloses an electric heating pot with a constant temperature controlling device, comprising a pot body (13) and a base (14). The base (14) is provided with the constant temperature controlling device inside which is connected with a heating switch (4) or a switch (5) or a switch (6) in parallel. The constant temperature controlling device can make a heating device work within a set temperature range. When the utility model is used, so long as heating switches (4), (5), and (6) are switched off and a change switch (11) is dialed to a temperature position which needs to be set, the temperature of the utility model can be kept in set temperature, and indicating lamps (10) and (12) on the base indicate the work state of the utility model. The utility model increases the use functions of electric heating pots and saves electric energy.
Description
The utility model relates to a kind of electric food warmer with thermostatically-controlled equipment.
Along with the raising of people's living standard, the temperature that food is heated has proposed diversified requirement, yet the electric food warmer on the present market all has only the overtemperature prote function, promptly takes the mode of outage automatically to protect electric food warmer not burnt out when temperature reaches upper limit (UL).
The purpose of this utility model provides and a kind ofly can not be higher than on arbitrary temperature of the maximum temperature limit electric food warmer that keeps constant temperature.
In order to achieve the above object, the electric food warmer of band thermostatically-controlled equipment of the present utility model is made up of pot body (13) and base (14), and heater and thermostatically-controlled equipment are arranged in the base.Thermostatically-controlled equipment is connected in parallel on heater switch (4), (5), (6), makes when heater switch disconnects the thermostatically-controlled equipment effect.Two cavitys are arranged on the base, and its shape, size are corresponding with thermostatical pilot lamp (12) with burner on light (10) respectively, place burner on light (10) and thermostatical pilot lamp (12) respectively.
After adopting this structure, because thermostatically-controlled equipment is connected in parallel on heater switch (4), (6), (6), when heater switch was closed, thermostatically-controlled equipment was inoperative, can heat rapidly; When needs constant temperature, can disconnect heater switch, this moment, thermostatically-controlled equipment worked, and forwarded change-over switch to corresponding temperature controller place, and electric food warmer is remained on the temperature of setting; Increased by two indicator lamps that show heated condition and temperature constant state because the end is taken again, two indicator lamps are alternately lighted during electric food warmer work, and are not only attractive in appearance but also be convenient to the working condition that the user understands electric food warmer.Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the electric food warmer of the utility model band thermostatically-controlled equipment.
Fig. 2 is the heating and the temperature-control circuit schematic diagram of the electric food warmer of the utility model band thermostatically-controlled equipment.
The electric food warmer of band thermostatically-controlled equipment shown in Figure 1 comprises: pot body (13), base (14) and heating and thermostatically-controlled equipment constitute.Heating and thermostatically-controlled equipment are installed in the cavity of base.Heater switch (4), (5), (6) and temp control switch (11) are installed on the base.
Fig. 2 has provided the circuit diagram of heating and thermostatically-controlled equipment.During heated condition, civil power is added to heater switch through temperature controller (1) and holds concurrently on the switch (4), (5), (6) of indicator lamp, and when switch (4) was closed, electrothermal tube had electric current to pass through in (7), and electrothermal tube (7) begins heating; When switch (5) was closed, electrothermal tube (8) began heating; When switch (6) is closed, electrothermal tube (9) heating.Adjust the combinations of states of switch (4), (5), (6), can control firing rate.
When the temperature of electric food warmer reached a high temperature the temperature of protecting, temperature controller (1) disconnected, no matter which kind of state switch (4), (5), (6) are at this moment, electrothermal tube (7), (8), (9) all do not generate heat.
When needs constant temperature, switch (4), (5), (6) disconnect, and simultaneously change-over switch (11) are placed on the temperature position that needs.When change-over switch (11) places (11-1) when locating, civil power is added on the electrothermal tube (9) through temperature controller (2), electrothermal tube (9) heating, burner on light (10) is lighted simultaneously, and when temperature was higher than the temperature of setting, temperature controller (2) disconnected, electrothermal tube (9) dead electricity, stop heating, burner on light (10) extinguishes, and thermostatical pilot lamp (12) is lighted.
The constant temperature temperature controller can be selected also can select the temperature controller of different temperature coefficients as required by adorning one or more as required.
The thermostat temperature control circuit can be connected in parallel on switch (4) or switch (5) or the switch (6) as required.
Because the utility model has increased a plurality of temperature controllers in circuit, the temperature of electric food warmer can arbitrarily be controlled, and has increased the purposes of electric food warmer, saves energy and easy to use.
Again since the utility model at the base of electric food warmer by having adorned two indicator lamps that show heating and temperature constant state respectively, be convenient to the duty that the user understands electric food warmer.
Claims (3)
1, a kind of electric food warmer with thermostatically-controlled equipment, comprise a pot body (13), base (14) and place the interior heater of base, it is characterized in that a thermostatically-controlled equipment is arranged in the base, this thermostatically-controlled equipment can make heater work in range of set temperature.
2, the electric food warmer of band thermostatically-controlled equipment according to claim 1, it is characterized in that, this thermostatically-controlled equipment comprises a change-over switch (11) and a plurality of temperature controller, temperature controller inserts each contact of change-over switch respectively, make under the various situations of change-over switch to have only a temperature controller place in circuit at most.
3, the electric food warmer of band thermostatically-controlled equipment according to claim 1 and 2 is characterized in that being equipped with on the base indicator lamp (10) that shows heated condition and the indicator lamp (12) that shows temperature constant state.
