Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments, but the scope of the present invention is not limited to the following specific embodiments.
As shown in fig. 1, a temperature indicating device includes a first snap-action temperature controller 1, a second snap-action temperature controller 2, a temperature control indicator lamp 5, a shift indicator lamp 9 and a heating pipe 3, wherein the first snap-action temperature controller 1 and the second snap-action temperature controller 2 are disposed at the same position of the same object, and a maximum temperature control temperature T1 of the first snap-action temperature controller 1 is greater than a maximum temperature control temperature T2 of the second snap-action temperature controller 2.
The kick type temperature controller is a heat sensitive reaction component which takes a bimetal wafer after temperature setting, when the temperature of a main part of a product is increased or decreased, heat generated is transferred to the bimetal wafer to quickly act when the action temperature is set, and a contact is opened or closed through the action of a mechanism to achieve the purpose of connecting or disconnecting a circuit, thereby controlling the circuit.
Specifically, the resistances of the first snap-action temperature controller 1 and the second snap-action temperature controller 2 are almost zero, the set temperature is a fixed value, when the collected temperature reaches the set temperature value, the circuit is switched off, and when the temperature is reduced, the circuit is automatically switched on.
The first kick type temperature controller 1 is a first branch circuit; the second kick type temperature controller 2 is connected with a temperature control indicator lamp 5 in parallel and then connected with a resistor in series to form a second branch circuit;
the gear indicator lamp 9 is connected with a resistor in series to form a third branch circuit;
the heating pipe 3 forms a fourth branch;
the first branch and the fourth branch are connected in series to form a fifth branch; the second branch and the third branch are connected with a fifth branch in parallel; and a switch 10 is arranged on a combining path of the second branch, the third branch and the fifth branch which are connected in parallel.
Specifically, the value of T1 is between 100 and 200 degrees, further between 150 and 170 degrees, in this embodiment, the value of T1 is 170 degrees; the value of T2 is 130-160 degrees, and further, 140-160 degrees, in this embodiment, the value of T1 is 160 degrees.
When the value of T1 is 170 degrees and the value of T1 is 160 degrees, the shift indicator lamp 9 is turned on when the switch 10 is closed, and it is known that the shift position is changed. When the temperature of the surface of the object reaches 160 ℃, the second kick temperature controller 2 is disconnected, the indicating lamp circuit is conducted at the moment, and the temperature control indicating lamp 5 is lightened; then the heater 3 continues to heat, when the temperature of the object reaches 170 ℃, the first kick temperature controller 1 is switched off, at the moment, the heater 3 does not continue to heat, and the temperature control indicator lamp 5 continues to light up; because the temperature of the heating pipe 3 is not heated to the object and is slowly reduced, when the temperature is lower than 170 ℃, the first kick type temperature controller 1 is switched on again, and the heating pipe 3 is heated again; if the temperature is lower than 160 ℃, the second snap-action thermostat 2 is turned on again, because the resistance of the second snap-action thermostat 2 is almost zero, the voltage at the two ends of the temperature control indicator lamp 5 is also 0, and therefore the indicator lamp is turned off. Therefore, as long as the temperature of the object is between 160 and 170, the temperature control indicator lamp 5 is always on to play the indicating role.
The first set of T1 is 170 degrees, meaning that we expect the temperature to be controlled between 160-170 degrees. In fact, when the temperature reaches 170 ℃, the temperature controller will cut off the circuit, and the heating pipe stops heating; when the temperature drops to about 160 ℃, the temperature controller is connected with the circuit, and the heating pipe continues to heat. This approach will actually control the temperature between 160-170 deg.f. For this reason, we set T2 to 160 degrees. When the temperature reaches 160 ℃, the temperature controller 2 is disconnected with the circuit, the temperature control indicator lamp 5 is lightened, and people know that the controlled temperature reaches the temperature immediately and can start to fry.
Preferably, a protective temperature controller 6 for protection is further connected in series between the first sudden-jump temperature controller 1 and the heating pipe 3, and the protective temperature controller 6 is used for measuring and controlling the temperature at the bottom of an object, preventing the temperature from being too high, and playing a role in protection. Whole device inserts the power, still is provided with power indicator 7, a resistance is established ties to power indicator 7, in order to distinguish with preceding resistance, names second resistance 8, power indicator 7 with second resistance 8 establish ties after again with first branch road parallel connection, after the switch-on, power indicator 7 is bright.
The temperature indicating device of the utility model can be arranged on a pot and a heating kettle, and can be applied to all products needing temperature indication in a certain interval.
The first branch circuit, the second branch circuit, the third branch circuit and the switch are provided with a plurality of groups, and the first branch circuit of any group is connected with the fourth branch circuit in series to form a fifth branch circuit; the second branch and the third branch of any group are connected with the corresponding fifth branch, the combined circuit formed by connecting the second branch, the third branch and the fifth branch of any group in parallel is connected with the corresponding combined circuits of other groups in parallel, and the switch of any group is connected with the switches of other groups in parallel.
As shown in fig. 2, in the present embodiment, the first branch, the second branch, the third branch and the switch are arranged in 2 groups. Wherein each element in the second group is numbered correspondingly: a first kick type temperature controller-21, a second kick type temperature controller-22, a resistor-24, a temperature control indicator lamp-25, a gear indicator lamp-29 and a switch-210.
For the multiple group case, the operation is described as follows:
for example, in the first group, the set temperatures of the first snap-action thermostat and the second snap-action thermostat are respectively: t11 ═ 170, T12 ═ 160;
in the second group, the set temperatures of the first snap-action temperature controller and the second snap-action temperature controller are respectively as follows: t21 ═ 150, T22 ═ 140;
when "one group" is selected, when the switches of one group are closed, the shift indicator lamp 9 in one group is turned on, but the "temperature control indicator lamp 5" is not turned on. The control temperature of 160-170 is proved to be selected, but the temperature is not reached; when the temperature control indicator lamp 5 is turned on, the control temperature is reached. Similarly, if switching to two groups, the same phenomenon occurs.
As shown in fig. 3, an electric cooker with a temperature indicating device includes a cooker body 11 and a temperature indicating device disposed on the cooker body. The first kick type temperature controller 1 and the second kick type temperature controller 2 are both arranged on the side wall of the cooker body 11; the heating pipe 3 and the protection temperature controller 6 are arranged at the bottom of the cooker body and are in contact with the cooker body.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention. In addition, although specific terms are used in the specification, the terms are used for convenience of description and do not limit the utility model in any way.
