Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric heating cooker in which a flat heat-resistant plate is used for a portion on which a cooking vessel is placed and heated, and a halogen lamp is used as a heat source.

2. Description of the Related Art Conventionally, as shown in FIG. 5, an electric cooker of this type includes a heat-resistant glass 1 for placing and heating a cooking vessel, an appliance main body 2 provided with the heat-resistant glass 1 in an upper opening, and an appliance. A heater unit 3 housed in the main body 2 and provided between the main unit 2 and the heat-resistant glass 1, a halogen lamp 4 serving as a heat source of the heater unit 3, and a temperature of the heat-resistant glass 1 near the heater unit 3 are approximately detected. And a light-emitting indicator 6 housed in the instrument body 2 and receiving a detection signal from the temperature detector 5 so that a light-emitting portion emits light through the heat-resistant glass 1. 3 was heated to generate heat, and the cooking vessel was heated from the heat-resistant glass 1. When the operation of the heater unit 3 is stopped when the operation is stopped, the temperature of the heat-resistant glass 1 is high due to residual heat.
The temperature detector 5 detects and the controller 7 emits or blinks the light-emitting indicator 6 to warn the user not to touch the heat-resistant glass 1.

However, in the above-described configuration, when the heater unit 3 stops operating and the heat-resistant glass 1 still has residual heat, the light-emitting display 6 performs light-emitting display through the heat-resistant glass 1. Since the back surface of the glass 1 was uneven, light was scattered and it was difficult for a user to understand. In addition, since the number of the light emitting displays 6 is one, the display capability is weak, and it is similarly difficult to understand. Also, there was no way to distinguish which heater unit 3 had residual heat. So, by mistake, heat-resistant glass 1
There was a problem of getting burned by touching the hand.

Therefore, according to the present invention, when the heat-resistant glass has residual heat, a display that is easy for the user to understand is displayed and the heat-resistant glass 1
The primary purpose is to solve the problem of getting burned by touching the hand.

A second object is to provide an easy-to-understand display without hindering the cooling of the residual heat of the heater unit.

A third object is to provide an easy-to-understand display without hindering the cooling of the residual heat of the heater unit.

Means for Solving the Problems In order to achieve the first object, the present invention is provided with a controller that receives a detection signal of a temperature detector and causes a halogen lamp to emit light at regular intervals.

Further, in order to achieve the second object, the present invention is provided with a controller which receives a detection signal of a temperature detector, reduces power supplied to a halogen lamp, and emits light at regular intervals.

In order to achieve the third object, the present invention is provided with a controller that receives a detection signal of a temperature detector and causes some of the plurality of halogen lamps to emit light at regular intervals in response to a detection signal.

According to the electric heating cooker according to the present invention, when the heat-resistant plate has residual heat, the controller causes the halogen lamp to emit light at regular intervals, so that the entire heating surface of the heater unit emits light. This makes it easier to see which of the plurality of heater units has residual heat.

The controller reduces the power supplied to the halogen lamp and emits light at regular intervals, so it generates less heat and does not hinder the cooling of the surplus heat of the heat-resistant plate. It becomes.

Furthermore, since the controller causes some of the plurality of halogen lamps to emit light at regular intervals, the heat generated from the lamps is small, and there is no hindrance to the cooling of the residual heat of the heat-resistant plate. It is easy to understand that there is.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

In FIGS. 1 and 2, reference numeral 7a denotes a controller. When the heat-resistant glass 1, which is a heat-resistant plate, has residual heat immediately after the operation is stopped, the halogen lamp 4 is kept constant by receiving a detection signal from the temperature detector 5. Is controlled so as to emit light at intervals of.

Next, the operation of the configuration of the embodiment will be described.
First, the case where the heater unit 3 is energized to heat the cooking container will be described. When the heater unit 3 is energized, the halogen lamp 4 emits light and generates heat, and the portion of the heat resistant glass 1 corresponding to the heater unit 3 rises to a high temperature. Therefore,
The cooking container placed on the heat-resistant glass 1 is also heated.

Next, a case where the power supply to the heater unit 3 is stopped to stop the operation will be described. When the power supply to the heater unit 3 is stopped, the heater unit 3 stops generating heat, but the portion of the heat resistant glass 1 corresponding to the heater unit 3 has residual heat. Then, receiving the detection signal of the temperature detector 5,
The controller 7a causes the halogen lamp 4 to emit light at regular intervals.

 Next, a second embodiment will be described with reference to FIG.

In the figure, if there is residual heat immediately after operation stop,
In 7a, since the power supplied to the halogen lamp 4 is reduced to emit light at regular intervals, the heat generated from the halogen lamp 4 is small, and it is easy to understand that there is residual heat without hindering the cooling of the residual heat of the heat-resistant glass. It can be displayed. Also, it can be seen which heater unit 3 has residual heat.

 Next, a third embodiment will be described with reference to FIG.

In the figure, if there is residual heat immediately after the operation is stopped, the controller 7a causes some of the halogen lamps 4a to 4d to emit light at regular intervals among the plurality of halogen lamps 4a to 4d. This does not hinder the cooling of the residual heat of the heat-resistant glass, but makes it easier for the user to recognize that there is residual heat. In the embodiment, the halogen lamps 4b to 4c emit light. However, the present invention is not limited to this, and another halogen lamp may be used.

Effect of the Invention As described above, the present invention provides a controller that receives a detection signal of a temperature detector and causes a halogen lamp to emit light at regular intervals. The entire area emits light, and it is easy for the user to know that there is residual heat, and it is easy to see which of the plurality of heater units has residual heat.

In addition, the present invention provides a controller that receives a detection signal from the temperature detector and reduces the power supplied to the halogen lamp to emit light at regular intervals, so that when there is excess heat, the heat generated from the halogen lamp is reduced. This does not hinder the cooling of the residual heat of the heat-resistant plate and makes it easier for the user to recognize that there is residual heat.

Further, according to the present invention, by providing a controller that receives a detection signal of the temperature detector and causes some of the plurality of halogen lamps to emit light at regular intervals, a heat generated from the halogen lamp is provided when there is residual heat. Is small and does not hinder the cooling of the residual heat of the heat-resistant plate, so that the user can easily recognize that there is residual heat.
