The present invention relates to a rice cooker having a base body on which an inner pot is placed and installed inside the rice cooker body; A cover portion mounted on a bottom surface of the base body; A holder part which is fastened to each other at a lower portion of the cover part and in which a PCB is mounted; A temperature sensor member mounted on the holder portion and positioned in the cover portion; And a shielding member mounted on the holder to surround the temperature sensor member.
Description
The present invention relates to a contactless temperature sensor assembly for a rice cooker, and more particularly, to a contactless temperature sensor assembly for a rice cooker capable of measuring a temperature without directly contacting the inner pot of the rice cooker.
In general, a cooking device such as a rice cooker refers to a device used for cooking food, and is divided into a resistance heater heating method and an induction heating method according to a heating method for cooking. The induction heating method refers to induction heating (IH) in which an inner pot housed inside the main body is induced by electromagnetic induction when a high frequency current is supplied to a coil wound around a lower portion of the main body.
1B is a cross-sectional view showing a configuration of a conventional contact type temperature sensor assembly applied to a conventional induction heating pressure cooker. FIG. 1A is a schematic view showing a configuration of a conventional induction heating pressure cooker.
As shown in FIG. 1A, a conventional induction heating pressure cooker is constructed by heating an

The
When a high frequency current controlled by the controller is applied to the
Meanwhile, the conventional induction heating pressure cooker is generally equipped with a contact type temperature sensor assembly. For example, as shown in FIG. 1B, a working
A contact type temperature sensor assembly is mounted on the working
Accordingly, when the inner pot (not shown) is mounted in the
However, such a conventional contact type temperature sensor assembly has the following problems.
First, since the contact type temperature sensor assembly is subjected to temperature measurement only by contact, a structural consideration for efficient contact must be preceded, which makes it difficult to accurately measure the temperature.
Secondly, since the sensor
<Prior art>: Korean Patent Publication No. 2012-0000164 (Jan. 02, 2012)
The present invention provides a noncontact type temperature sensor assembly for an electromagnetic cooker which is developed for solving the above problems and is capable of accurately measuring temperature by noncontact sensing and improving airtightness to improve durability and prevent damage to the device .
According to an aspect of the present invention, there is provided a cooking apparatus comprising: a base body on which an inner pot is placed and installed inside a rice cooker main body; A cover unit integrally formed on a bottom surface of the base body; A temperature temperature sensor member located inside the cover portion and electrically connected to the PCB; And a shield member mounted on the bottom surface of the base body and mounted to surround the temperature sensor member.
And a holder portion which is opened at a part of the bottom surface of the base body and is fastened to each other at a lower portion of the cover portion.
A penetrating hole may be formed at the center of the cover portion so as to pass through the upper and lower portions, and a penetrating plate may be attached to the entrance side of the penetrating hole.
The temperature sensor member may be an infrared sensor.
The upper surface of the cover portion may be inclined toward the edge.
According to the present invention, accurate temperature measurement can be performed through a non-contact sensor (infrared sensor) provided inside the cover part, and the cover part is housed inside the sensor, thereby improving airtightness and securing device damage and airtightness.
