Description

Improved text stove

Technical field

The utility model relates to a kind of electrical heated appliance, the improved text stove of particularly a kind of heater circuit.

Background technology

The Chinese patent communique discloses that a kind of patent No. is 01238225.6, name is called the utility model patent of " electric hot tray of card sealing ", this patent solved heat preservation component need be without mould prefabricated and heat preservation component thickness can freely regulated problem; It is the improvement that Chinese utility model patent 99229770.2, name is called " electric hot tray of card sealing ".This product is on sale on market, it mainly is used on the text pot, the heater circuit of this product plugs in as shown in Figure 1, and A, B end obtains 220 volts of civil powers, press the power supply pass and open K1, select the power that heats then, K2 beats when the C20 place, and resistive heater RW all inserts, resistance is bigger, and heating power is low; K2 beats when the C21 place, and resistive heater RW partly inserts, and resistance is less, the heating power height; Because no matter K2 is in C20 place or C21 place, the value of resistive heater all is bigger, therefore heating power is all lower, therefore, can only produce low-grade fever, because constantly gathering of energy, heated vessel heat up gradually, and this product can not produce the delicious characteristics of food that soup stock overflows and makes in power saving, system dish process; But in the process of using, for culinary art quickly, this product must be heated to boiling by first dish material with required pot in pot, and then pot or vessel is placed on this electric hot tray heating again; This mode has been brought great inconvenience to use.

The utility model content

The purpose of this utility model is in order to solve above-mentioned trouble, a kind of improved text stove to be provided, and it is realized by the following technical solutions:

Improved text stove, it comprises: electric hot tray, text stove pan body assembly, the control circuit of card sealing; The electric hot tray of described card sealing comprises: chassis 1, metallic plate 2, heat transfer plate 3, electric heating assembly 4, heat preservation component 6, pan arrest 7, described heat preservation component 6 is formed by folded the establishing of asbestos wadding, its underpart is positioned at the cavity volume 9 of pan arrest 7, and top then is positioned at the cavity on chassis 1; Described metallic plate 2 is positioned at the cavity on chassis 1 and is fixed on the inner surface on chassis 1, and the rim on described chassis 1 is provided with some air-vents 12, and described heat preservation component 6 integral body present the cylinder table shape; Described heat preservation component 6 is provided with some passages 8 at the central portion of pan arrest 7; It is characterized in that: also have temperature control component 15 between chassis 1 and the metallic plate 2; Also has a cover heating element heater R1 on the described electric heating assembly 4 in addition; Described control circuit is characterised in that: power supply enters the input A of plug, the end of input A and power switch K1 joins, the common port of the other end order cutter on-off switch K2 of power switch K1 and the end of temp control switch K3, the end of another termination heating element heater R1 of temp control switch K3, another termination power of heating element heater R1 enters the input B of plug, one joint C20 of the non-common port of hilted broadsword on-off switch K2 connects the end of electric heating assembly RW, another joint C21 of the non-common port of hilted broadsword on-off switch K2 connects electric heating assembly RW transition joint, and another termination power of electric heating assembly RW enters the input B of plug.

Above-mentioned described temperature control component 15 is bimetal release K3 or magnet steel temperature limit switch K3.

The temperature-control range of above-mentioned described temperature control component 15 is 98 ± 2 ℃.

Operation principle of the present utility model is: plug in earlier, A, B holds, press power switch K1, and heater switch, at this moment, since temperature not within the temperature-control range of temperature control component 15, therefore, temp control switch K3 conducting, because K3, the R1 series connection is connected between the common port and power input B of hilted broadsword on-off switch K2, and the power of R1 is bigger, therefore heating rapidly, within 98 ± 2 ℃, K3 disconnects, and R1 no longer heats, at this moment, because RW has in the part or all of place in circuit, so, but, can only make temperature maintenance near 98 ℃ because its power is less still in heating, and reached that pot interior food is continued is vexed ripe, vexed mashed effect, and the boiling that can not produce soup stock is overflowed.

In the utility model owing to adopted additional heating element heater R1 and temperature control component 15, make in each heating process, reach near the function that just disconnects additional heater circuit 98 ℃ when temperature, therefore, product is intelligent more, use more conveniently, do not need earlier not put into the heating of text stove again after the heating elsewhere.

The specific embodiment

Embodiment one:

Ask for an interview Fig. 2 and Fig. 3, improved text stove, it comprises: electric hot tray, text stove pan body assembly, the control circuit of card sealing; The electric hot tray of described card sealing comprises: chassis 1, metallic plate 2, heat transfer plate 3, electric heating assembly 4, heat preservation component 6, pan arrest 7, described heat preservation component 6 is formed by folded the establishing of asbestos wadding, its underpart is positioned at the cavity volume 9 of pan arrest 7, and top then is positioned at the cavity on chassis 1; Described metallic plate 2 is positioned at the cavity on chassis 1 and is fixed on the inner surface on chassis 1, and the rim on described chassis 1 is provided with some air-vents 12, and described heat preservation component 6 integral body present the cylinder table shape; Described heat preservation component 6 is provided with some passages 8 at the central portion of pan arrest 7; It is characterized in that: also have temperature control component 15 between chassis 1 and the metallic plate 2; Also has a cover heating element heater R1 on the described electric heating assembly 4 in addition; Described control circuit is characterised in that: power supply enters the input A of plug, the end of input A and power switch K1 joins, the common port of the other end order cutter on-off switch K2 of power switch K1 and the end of temp control switch K3, the end of another termination heating element heater R1 of temp control switch K3, another termination power of heating element heater R1 enters the input B of plug, one joint C20 of the non-common port of hilted broadsword on-off switch K2 connects the end of electric heating assembly RW, another joint C21 of the non-common port of hilted broadsword on-off switch K2 connects electric heating assembly RW transition joint, and another termination power of electric heating assembly RW enters the input B of plug.

Operation principle of the present utility model is: plug in earlier, A, B holds, press power switch K1, and heater switch, at this moment, since temperature not within the temperature-control range of temperature control component 15, therefore, temp control switch K3 conducting, because K3, the R1 series connection is connected between the common port and power input B of hilted broadsword on-off switch K2, and the power of R1 is bigger, therefore heating rapidly, within 98 ± 2 ℃, K3 disconnects, and R1 no longer heats, at this moment, because RW has in the part or all of place in circuit, so, but, can only make temperature maintenance near 98 ℃ because its power is less still in heating, and reached that pot interior food is continued is vexed ripe, vexed mashed effect, and the boiling that can not produce soup stock is overflowed.So far, finished goal of the invention of the present utility model.

This paper understands the utility model exemplary embodiment and present preferred embodiment specifically, should be appreciated that the utility model design can be by other various forms enforcement utilizations, and they drop in the protection domain of the present utility model equally.
