Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] This invention relates to an induction heating device, and more particularly to an improvement of an induction heating device in which the induction heating operation can also be controlled using a temperature probe.

[Technical background of the invention and its problems]

2. Description of the Related Art In an electromagnetic induction cooking device such as an induction heating device, cooking is usually performed by adjusting the output of a heating coil installed inside the cooking device.
However, when cooking with such output adjustment, the pot etc. generates heat just by adjusting the output, so temperature control for food tends to be rough, and cooking of temperature-sensitive foods is not satisfactory. There are drawbacks.

Therefore, electromagnetic induction cooking devices have been developed that use temperature probes to enable detailed temperature control. This type of electromagnetic induction heating cooker uses a temperature probe with a temperature sensor section and a plug connected by a long cable.
The plug of this temperature probe is removably connected to the insertion part provided in the cooker body, and the temperature sensor is connected to the induction heating circuit built into the cooker body through the insertion part, thereby controlling the temperature of the food. I try to cook based on this.

By the way, as shown in FIG. 1, this type of electromagnetic induction heating cooker has conventionally provided an insertion part b on the upper surface side of the cooker main body a, and a temperature probe (not shown) is provided in the insertion opening of this insertion part b. (not installed).

However, with such a structure in which the insertion part b is provided on the top side of the cooking device main body a, during cooking when the temperature probe is not used, foreign objects such as food juices may enter the cooking device including the top plate c. If food spills or food scraps spill onto the top surface of the cooker body a, those liquids, crumbs, etc. will enter the socket of the socket b, causing poor insulation or clogging. There is an inconvenience. For this reason, it is inferior in safety and also brings about problems in reliability when using a temperature probe. Moreover, the structure in which the insertion part b is provided on the upper surface side of the cooking device main body a is such that the insertion part b and the insertion part b are
The plug inserted into the
The object to be heated is very likely to interfere with the insertion part b or the plug protruding from the insertion part b, and there is a great possibility that the insertion part b and the plug of the temperature probe will be damaged by external force.

[Purpose of invention]

This idea was developed in light of the above circumstances, and its purpose is to create an induction heating device that is safe, reliable, and durable, avoiding troubles that occur with the insertion part and temperature probe plug. It is about providing.

[Summary of the idea]

This idea is to provide a recess in the side of the heating device body, provide an insertion part for receiving the plug of the temperature probe in this recess, and set the depth of the recess to a space where the inserted plug does not protrude from inside the recess. By configuring the insertion part within the recess, it is possible to avoid foreign matter from entering the insertion part from the top surface of the heating device main body, and also to avoid interference with the insertion part. This is intended to prevent troubles that may occur with the plug of the temperature probe by avoiding interference with the plug that is inserted.

[Example of idea]

This invention will be explained below based on an embodiment shown in FIGS. 2 to 4. In Fig. 2, 1 is the main body of the electromagnetic induction cooking device (hereinafter referred to as the main body), which is the main body of the induction heating device, 2 is the top plate attached to the top side of the main body 1, and 3 is the top plate 2. The cooking lamp 4 and output display section 5 are displayed on the panel surface provided on the right side of the upper surface of the main body 1 adjacent to the
6 is a fly-type power switch, and 7 is a slide-type output adjustment knob. Further, as shown in FIG. 4, inside the main body 1, a heating coil 8 is provided facing the top plate 3, and a power supply circuit section 9 having a built-in inverter circuit for driving the heating coil 8 is further provided. A control circuit section 10 is provided to control the power supply circuit section 9 in response to the operation of the switch 6 and the output adjustment knob 7. It constitutes an induction heating circuit 20 that can generate heat.

The electromagnetic induction cooking device configured as described above is designed to allow detailed temperature control of cooking using the temperature probe 12. That is, the temperature probe 12
As shown in FIG. 3, a rod-shaped temperature sensor portion 14 is connected to the tip of a long cable 13, and a plug 15 having a jack portion 15a at the tip is connected to the base. Further, a recess 16 is provided on the right side of the main body 1 adjacent to the display panel 3 of the main body 1 over the entire width direction of the right side, and the side surface inside this recess 16 is connected to the power supply circuit section 9. An insertion section 17 is disposed together with the power switch 6 and the output adjustment knob 7, and as shown in FIG. 4, the plug 15 of the temperature probe 12 can be detachably inserted into the insertion section 17. This allows the induction heating operation using the temperature probe 12 to be performed appropriately. Therefore,
Due to the provision of the recess 16 and the installation on the side of the main body 1, the insertion part 17 is placed in a position where it is extremely difficult for foreign matter, such as food juice and food scraps, to enter from the top surface of the main body 1. Further, the depth of the recess 16 is such that the plug 15 does not protrude from the inside of the recess 16 when the plug 15 is inserted into the insertion portion 17. The structure is such that it is extremely difficult to come into contact with (interference with) the pot 11 and the like. In addition, the plug 15 of the temperature probe 12 has a jack portion 15a.
For example, a disc-shaped collar 18 formed into a concave shape is provided on the base side of the cable 13, and this collar 18 serves as a blocking part to prevent food juice from flowing through the cable 13 toward the insertion part 17. It is designed to prevent the intrusion of liquids such as water and steam condensate (water droplets).

On the other hand, for the pot 11 as the object to be heated, a dedicated cooking container suitable for the temperature probe 12 is used. Now, if I explain about the pot 11,
As shown in FIG. 4, a sensor storage chamber 19 corresponding to the shape of the temperature sensor section 14 of the temperature probe 12 is provided on the bottom wall 11b of the container body 11a, which is made of a material suitable for induction heating such as iron or stainless steel. The pot 11 is configured by inserting and removing the
By housing the temperature sensor part 14 in the sensor housing chamber 19 and performing cooking using the temperature probe 12, stable temperature control can be obtained in combination with the dedicated pot 11. Note that the pot 11 is prepared in various ways depending on the cooking purpose, such as one for tempura, one for teppanyaki, and others.

When cooking using the special pot 11 and temperature probe 12 using the electromagnetic induction cooking device configured as described above, the pot 11 containing food is placed correctly on the top plate 3, and then the The temperature sensor part 14 of the temperature probe 12 connected to the insertion part 17 is inserted into the sensor housing chamber 19 of the pot 11 and set, and then the power switch 6 is turned on to start cooking from the temperature sensor part 14. While the temperature information of the food is being fed back, a high frequency current corresponding to the temperature information is supplied to the heating coil 8 from the power supply circuit section 9, and an eddy current is generated in the pot 11 through the high frequency magnetic field generated by the heating coil 8, and the pot 11 is heated. It will cause heat generation. However, the food temperature probe 1
The food is cooked by controlling the operation of induction heating according to No. 2.
Note that when the dedicated pot 11 is not used, the temperature sensor section 14 of the temperature probe 12 may be inserted directly into the food.

When cooking without using the special pot 11 and temperature probe 12, set the pot 11 containing food on the top plate 3, turn on the power switch 6, and turn the output adjustment knob 7 as required. By setting this, the pot 11 generates heat through the heating coil 8, and cooking can be carried out over a wide range.

However, during such cooking, conventionally food juices and liquids spilled onto the top surface of the main body 1 as foreign substances.
There is a problem that debris enters the insertion part 17 and causes poor insulation or even clogging at the insertion opening, and furthermore, the insertion part 17 and the plug 15 inserted into the insertion part 17 may be damaged when moving or setting the pot 11, etc. Interfering with the insertion part 17,
However, in this invention, the insertion part 17 is placed in the recess 16 provided on the side of the main body 1, so that the food juice does not reach the top surface of the main body 1. Even if food spills or food debris spills, it will only reach the wall forming the recess 16 and will not reach the insertion part 17 inside the recess 16.
This makes it possible to avoid foreign matter from entering the insertion portion 17. Therefore, poor insulation in the insertion part 17,
Clogging can be prevented. Further, since the recess 16 is configured with a space dimension that prevents the plug 15 from protruding from the recess 16, the insertion portion 17 and the plug 15 are protected from interference from the outside in the recess 16, and the plug 15 is protected from interference from the outside. It becomes possible to prevent the pan 11 and the like from hitting the receptacle 17 and the plug 15. Therefore, damage to the insertion portion 17 and the plug 15 due to external force can be prevented.

In this way, troubles occurring in the insertion portion 17 and the temperature probe 12 can be avoided with a simple structure, and safety, reliability, and durability can be improved.

In addition, in the above-mentioned embodiment, in addition to the insertion part, a power switch and an output adjustment knob are provided in the recess to protect not only the insertion part but also the power switch and the output adjustment nozzle, which is the most preferable embodiment. is given as an example, but only the insertion portion may be disposed in the recess.

Further, in the embodiment described above, the flange portion is provided on the plug portion of the temperature probe, but the flange portion may not be provided.
