Abstract

PURPOSE:To make suctioned cooling air flow directly toward an object to be cooled and to improve cooling efficiency by a method wherein an air fan is provided slantwise at a part adjacent to a bottom part and a side part within a body and a suction port for air sending is provided in a slanting part adjacent to the bottom part and the side part of the body to correspond to the air fan. CONSTITUTION:A pot 3 is inductance heated by an inductance coil 4 to make cooking. At this time, the inductance coil 4, a ferrite 5 and a control circuit 6 are cooled by an air fan 9. As a suction port 10 is provided in a connecting part of a bottom part and a side part of a body 1, air suction is very easy. Further, it is very rare that light weight substances such as polyethylene bags on a floor are absorbed to cause a suction trouble. In addition, cooling wind suctioned by the air fan 9 is sent directly toward objects to be cooled such as the control circuit 6, the inductance coil 4 and the ferrite 5, whereby cooling efficiency can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking appliance equipped with a heat source that heats by electric S induction.

BACKGROUND OF THE INVENTION In recent years, rice cookers and cookers that heat by electromagnetic induction, which have good thermal efficiency and high safety, have been widely used.

Conventionally, this type of cooking appliance has generally had a configuration as shown in FIG. The configuration will be described below with reference to the drawings.

As shown in the figure, the main body 1 constitutes a storage part for the pot 3 with a protective frame 2, and the bottom outer surface of the protective frame 2 is connected to an induction coil 4 for inductively heating the pot 3, which enhances inductive coupling and prevents leakage to the outside. A ferrite 5 is provided, and a control circuit 6 and a blower fan 7 for cooling the control circuit 6, the induction coil 4, and the ferrite 5 are horizontally provided at the bottom of the main body 1. An intake hole 8 is provided on the bottom surface of the main body 1 so as to face the blower fan 7, and an exhaust hole 9 is provided on the bottom surface of the main body 1 opposite to the blower fan 7.

Problems to be Solved by the Invention In such a conventional cooker, the air intake hole 8 of the blower fan 7
is located on the bottom of the main unit 1, so air must be taken in from the gap between the floor and the main unit 1, which increases wind resistance and reduces intake efficiency.Furthermore, when it picks up plastic bags placed on the floor, etc. It may also cause poor intake.

In addition, since the cooling air taken in by the blower fan 7 is drawn upward, it does not flow directly toward the control circuit, which is the object to be cooled, but after hitting the top surface, it flows in the direction of the control circuit, which reduces cooling efficiency. There was a problem with it being bad.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a cooking appliance in which the intake cooling air flows directly toward the object to be cooled, thereby improving the cooling efficiency.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a blower fan at an angle in the connecting portion of the bottom and side portions of the main body, and an intake hole for blowing air so as to correspond to the blower fan. It is provided on the sloped part where the bottom and side parts of the main body are connected.

Operation With the above-described configuration, the cooling air can directly cool the control circuit, induction coil, ferrite, etc. that are to be cooled, and air can also be taken in without any obstruction.

Embodiment One embodiment of the present invention will be described below with reference to FIG.

Note that the same components as in the conventional example are given the same reference numerals, and their explanations will be omitted.

The characteristic configuration of this embodiment is that the blower fan described in the conventional example is arranged slantingly inside the portion where the side and bottom portions of the main body connect. That is, the blower fan 9 is provided at an angle inside the part of the main body 1 where the bottom and side parts are connected, and the intake hole 10 is provided on the inclined surface where the bottom and the side part of the main body 1 are connected. Let's face each other. A control circuit 6 is arranged on the blowing side of the blower fan 9. Further, the exhaust hole 1° is provided on the bottom side of the main body 1 on the side opposite to the blower fan 9.

In the above configuration, the pot 3 is heated by induction by the induction coil 4 for cooking, and at this time, the induction coil 4. The ferrite 6 and the control circuit 6 are cooled by a blower fan 9. Since the air intake hole 10 is provided at the joint between the bottom and the side of the main body 1, it is easy to take in air, and light objects such as plastic bags on the floor F are often adsorbed, causing poor air intake.

Furthermore, the cooling air taken in by the blower fan 9 is directly supplied to the control circuit 6 which is the object to be cooled. Air is blown in the direction of the induction coil 4 and ferrite 6, increasing the cooling effect.

Effects of the Invention As is clear from the above description of the embodiments, the present invention provides an inclination to the inner side of the connected portion of the bottom and side of the whole body of the blower fan, and also connects the air intake hole of the blower fan to the bottom of the body. By providing it at the connecting part on the side, it is less likely that lightweight items such as plastic bags placed on the floor will be attracted to the intake hole and cause poor intake.

In addition, the cooling effect can be enhanced because air can be blown directly toward the control circuit, induction coil, and ferrite, which are the objects to be cooled.
