Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking appliance having a main body and a container that is detachably attached to the main body.

Conventional technology In general, a device has a main body and a container that can be attached to and detached from the main body, kneads the food to be cooked and cooks it using a mixing blade inside the container, and drives a drive motor to rotate the mixing blade. When attaching the container to the main body of the cooking appliance, a plurality of engagement protrusions 3 and engagement receiving parts 4 are attached to the container body attachment part 1 and the main body container attachment part 2, as shown in FIG. The main body 6 and the container 6 are engaged by the engaging protrusion 3 and the engaging receiving part 4 being provided (According to U.S. Pat.
-56481).

In many of these attachment parts, the retaining part 7 is tapered in order to facilitate the engagement work between the container body attachment part 1 and the main container attachment part 2 and to strengthen the engagement force.

Problem to be Solved by the Invention However, in the conventional engagement method using frictional force, when the main body 6 and the container 6 are attached and detached, a large frictional force acts on the engagement portion 7, causing the engagement protrusion 3 and the engagement The receiving part 4 is rubbed and the engagement force decreases each time it is used, and the engagement may come loose during operation.In a cooker in which the rotation direction of the kneading blades 8 can be reversed, the rotational force may cause the operation. The engagement in the middle is released, and the main body 5
There was a problem that the container 6 could come off.

In addition, since the engagement area of the engagement part 7 is small, force tends to concentrate locally, and when a large load is applied, the retention part 7 deforms, making it difficult to attach and detach the main body 6 and the container 6. , there was a problem that it would come off while driving.

In addition, in order to increase the engagement area, a plurality of engagement protrusions 3 are provided.
If the engaging receiving part 4 is used, the shape becomes complicated, making it difficult to attach and detach, and there is also a problem that food waste and water accumulate in the retaining part 7, which is unhygienic.

Nowadays, devices that are built into heating cookers such as toasters and microwave ovens have appeared, and when conventional cookers are built into these box-shaped refrigerators, they occupy more space inside the refrigerator than mentioned above. Due to this limitation, it becomes difficult to attach and detach the main body 6 and the container 6, and if the interior of the refrigerator is painted or surface-treated, the friction during engagement may damage the coating or surface treatment, resulting in failure. There was a problem that it could cause

The present invention solves these conventional problems, and by replacing the frictional force of the retaining part with magnetic attraction and repulsion, the retaining part is simplified, easy to attach and detach, and easy to maintain. To provide a highly reliable and safe cooking device which is easy to use and does not cause looseness due to wear or damage to paint or surface treatment.

Means for Solving the Problems The cooking appliance of the present invention has an attachment/detachment mechanism that uses magnetic force and applies its attraction and repulsion force as a means for attaching and detaching the container to the attachment portion of the main body and the mating portion of the container that can be detached from the main body. By providing this, it is an attempt to solve the conventional problems.

Function: The cooking device of the present invention utilizes magnetic attraction and repulsion between the main body and the attachment portion of the removable container on the main body, so that the engaging portion does not have an intrusive shape as in conventional cooking devices. , it has a flat shape. Therefore, it is not necessary to engage the engagement protrusion with the retaining portion as in the conventional case, and the attachment and detachment can be easily performed. Also, since it has a flat shape, it is easy to clean and hygienic.

In addition, whereas the conventional structure had a small retaining area and the force was easily concentrated locally, the cooker of the present invention
As mentioned earlier, since the locking part has a flat shape, the locking area can be large, the force is evenly distributed without local concentration, and the locking part does not shake due to deformation. do not have.

In addition, since the present invention utilizes attraction and repulsion of magnetic force instead of frictional engagement as in the past, there is no need to worry about abrasion of the retaining portion and no damage to the paint or surface treatment. .

Embodiments Hereinafter, embodiments of the cooking appliance of the present invention will be described with reference to the drawings. Figure 1 shows an embodiment applied to a microwave oven with a built-in cooker, showing a cross-sectional view of its main parts;
The figure is an enlarged view of the engaging portion.

In the figure, reference numeral 10 denotes an outer box forming body, which has a heating cooking chamber 11, and a main container attachment part 2 made of an electromagnet for attaching the container 6 to the bottom of the heating cooking chamber 11. The main container mounting part 2 and the container main body mounting part 1 are configured to be attracted and fixed by electromagnetic force generated by an electromagnet when the cooker is used. The kneading blade 8 transfers the rotational force of the drive motor 9 to a small pulley 12. Belt 13. The rotational force is transmitted to the rotating shaft 16 via the large 12° pulley gear 16, and is rotated by this rotational force. A heating cooking chamber 11 is used to heat the food to be cooked.
A magnetron 17 provided on the outer side surface of the cooking chamber 11 or a heater 18 provided above and below the heating cooking chamber 11 is used.

In this way, by arranging an electromagnet in the main container mounting part 2 and arranging a magnetic material in the container main body mounting part 1 so as to be attracted and fixed by electromagnetic force, the retaining protrusion 3 can be fixed as in the conventional case. Furthermore, there is no need to have the engagement receiving part 4, and the engagement surface' has a simple shape, making attachment and detachment easier.

Also, there is no need to damage or damage the inside of the refrigerator.
This is advantageous because problems such as wear and looseness are eliminated.

In addition, by providing the guider 19 on the retaining part 7, the attachment position is fixed, and attachment/detachment work becomes easier.
As a synergistic effect, a large engagement force can be obtained against lateral forces. At the same time, on the main body container attachment part 2,
By providing a detector 62o that checks the presence or absence of a container and prevents insufficient engagement, it is possible to prevent disengagement and the associated dangers. Furthermore, if the operating order of the cooker is performed as in the cooker according to claim 2, the cooker may operate without engaging the container main body attachment part 1 and the main body container attachment part 2, or the cooker may operate in the opposite direction. In addition, the danger of the bond breaking during cooking can be prevented. Detector 2o
It seems desirable for safety if used in combination with

FIG. 3 shows an engaging portion in the present invention when the engagement is achieved in combination with the conventional engagement method.

A magnet 21 is provided at the bottom of the container body attachment part 1, a magnetic body 22 is provided at a position facing the magnet 21 on the main body container attachment part 2, and at the same time, the conventional engagement protrusion 3 and engagement receiving part 4 are provided. They are provided in the container main body attachment part 1 and the main body container attachment part 2, respectively.

In this way, by using it in combination with the conventional engagement method, the shape of the engagement portion 7 is simplified compared to the case where only one frictional mechanical engagement is used. In addition, in the case of force and magnetism alone, a strong magnetic force is required because the engagement is somewhat small with respect to the lateral force, but when used in combination as described above, the engagement force is also strong in the lateral direction. can be obtained. Therefore, even when a large engagement force is required, attachment and detachment work can be easily performed.

Note that by providing the guider 19 on the retaining portion 7, the attachment position can be determined and attachment/detachment work can be more easily performed.

Effects of the Invention As described above, the cooking device of the present invention has a method of attaching and detaching the container and the main body by attraction and repulsion of magnetic force as an engagement method, as well as a conventional method of friction.

The container and main body are attached and detached using a combination of mechanical locking methods. By doing this, the retaining part is simpler than in conventional cookers, problems such as wear and deformation of the retaining part are eliminated, and it is easy to attach and detach, and it is also easy to maintain. Hygienic. Simplifying the structure of the engaging portion improves safety and reliability, which is extremely advantageous in practice.
