Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating cooker having a pull-out door.

In recent years, so-called built-in type heating cookers incorporating high-frequency heating devices, electrical openers, etc. have been developed and are gaining popularity in high-end homes and condominiums.

Particularly, in order to make effective use of narrow kitchen space, it is more convenient to use a drawer-type door that can be pulled back and forth than to open and close the door provided on a two-way heating cooker by rotating it.

To configure the door of the heating cooker in this way, by providing a tray holder on the inner wall of the door for placing the tray for the object to be heated, when the door is pulled out to the front of the main unit, the tray and the door will move to the front of the main unit at the same time. This makes it easy to use, as there is no risk of burns when taking out hot heated items after cooking.

However, since the inside of the heating chamber is heated to over 500'C, if the tray holder and the holder that locks the tray holder are made of a synthetic resin material with a low dielectric constant, they will lack heat resistance, so these should be replaced with metal materials. I have no choice but to configure it.

This metal tray holder is supported by a pair of holders and locking pieces provided on the left and right sides of the inner wall of the door, and is configured to be held at four or more fulcrums. In reality, it is always difficult to electrically contact all four fulcrum points.

If such a plate holder is used for high-frequency cooking and the table is far away from the table, sparks may occur, resulting in high-frequency loss, or the holder, locking piece, or plate holder may be abnormally heated by the high-frequency waves. This is extremely dangerous when removing the saucer from the heating chamber.

The present invention solves the drawbacks of the conventional heating cooker, and includes a high-frequency generator that supplies high-frequency waves into a heating chamber provided in the main body, and a high-frequency generator that supplies high-frequency waves into a heating chamber provided in the main body. It consists of a door that opens and closes by moving horizontally, a pair of metal holders provided on the inner wall of the door and having a plurality of locking pieces, and a tray holder on which a tray placed in the heating chamber is placed. B. The plate holder is made of an elastic metal material, and the plate holder is held in electrical contact with four supporting points of a pair of holders and a locking piece provided on the door. However, when cooking with high frequency, the plate holder is held in electrical contact with the holder and locking piece provided on the inner wall of the door, so the holder and locking piece and the plate holder are held together. There will be no sparks between the plates or the plate holder will heat up abnormally, so you can use a cheap one.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 6.

In Fig. 1, 1 is the main body of the heating cooker, and this main body 1
A door 3 is provided at the opening of a heating chamber 2 provided therein so as to be openable and closable. 4 is a rail provided on the door 3, and 6 is a roller provided on the rail 4, which is provided so that the door 3 can move horizontally in the front and back of the main body 1 to facilitate opening and closing. A magnetron 6 is used as an example of a high-frequency generator for supplying high-frequency waves into the heating chamber 2. The high-frequency waves generated by the magnetron 6 are supplied into the heating chamber 2 from an opening 8 through a waveguide 7. Reference numeral 9 denotes a pair of metal holders provided on the inner wall of the door 3, and the holders 9 are provided with a plurality of locking pieces 1O, 1C;

Reference numeral 11 denotes a metal plate holder that is held in electrical contact with the locking piece 1Q.A saucer 12 is placed on this plate holder 11, and food 13, which is an object to be heated, is placed on this plate holder 11.

As shown in FIGS. 3 and 4, it is composed of metal fittings a, bec, d, and e, and as shown in FIG. When engaged, the lower metal fitting and the locking piece 10 come into electrical contact, so that the plate holder 11 is supported by the holder 9.

When removing the plate holder 11 from the locking piece 1o and moving it to the upper locking piece 1d, lift the plate holder 11 upward as shown by the arrow in FIG. Easy to remove and move.

Next, the upper metal fitting d of the tray holder 11 is inserted into the recess 14 of the locking piece 1o.
The dimensions at which the lower metal fitting engages with the locking piece 1o and makes electrical contact with the locking piece 1o will be explained with reference to FIGS. 3 and 4.

First, the distance Q1 between the upper metal fitting d and the lower metal fitting e of the plate holder 11 is set to be 220 g in depth of the plate holder 11. The width is (between the locking pieces 10) of the tray holder 110 is set to be six times or more the distance m between the upper metal fitting d and the lower metal fitting 0.

6. The metal fittings used for the tray holder 11 are made of an elastic material, and are configured to be able to withstand the tray 12 or even when the food 13 is placed on the tray 12.

By configuring the plate holder 11 to such dimensions, even if there is some error in the dimensional accuracy of the locking piece 1o provided on the holder 9 or the dimensional accuracy of the plate holder 110, the plate holder 1
1 electrically contacts the upper metal fitting d and the fulcrums B and B' of the locking piece 100 and the lower metal fitting e and the fulcrums B and B' of the locking piece 10, thereby holding the plate holder 11. Due to the condition,
Even if the inside of the heating chamber 2 is preheated with high frequency without placing food 13 on the plate holder 11, the fulcrums M, M', B, and B' of the locking pieces 10 and the metal fittings d and e of the plate holder 11 will not be Sparks are unlikely to occur. Therefore, variations in high-frequency impedance within the heating chamber 2 are reduced, which significantly reduces the incidence of failures in the magnetron 6, and also prevents the plate holder 11 from being abnormally heated when preheating the heating chamber 2. There are no problems, so you can use it with confidence.

FIGS. 6 and 6 are page 7 showing another embodiment of the present invention, in which a recess 14 is provided in the holder 9, and a metal fitting d is provided in the recess 14.
are engaged with each other, and a metal fitting e is supported on the locking piece 1o to hold the plate holder 11 horizontally.

Further, the distance Q4 between the locking piece 1o and the locking piece 1d is set small so that the height of the plate holder 11 can be set at an optimal position depending on the size of the food 13 to be cooked.

By configuring the plate holder 11, the holder 9 that holds the plate holder 11, and the locking piece 10 in this way, the fulcrum of the holder e and the metal fitting d can be formed as shown in FIG.

Because they are held in electrical contact, no sparks are generated, and the plate holder 11 remains stable even when a large amount of food 13 to be cooked is placed on the plate holder 11. When the object to be heated is put in or taken out by pulling it out to the front of the saucer 1, the saucer 13 is not spilled, making cooking even more convenient.

As is clear from the above description, the heating cooker of the present invention is provided with a door at the opening of the heating chamber that opens and closes by moving back and forth horizontally with respect to the front surface of the main body, and a plurality of locking pieces are provided on the inner wall of the Q door. A heating cooker is incorporated into a kitchen set by providing a pair of metal holders, which hold a plate holder made of an elastic metal material in electrical contact with the holders. This makes it possible to make effective use of a small kitchen.

In addition, when preheating the heating chamber or cooking an object using high frequency, the holder and locking piece are in electrical contact with the plate holder, so no sparks are generated, and the high frequency generator The defect rate can be significantly reduced.

Furthermore, the plate holder is not heated abnormally, making it highly safe to use.Moreover, the holder is equipped with multiple locking pieces that hold the plate holder, making it easy to handle the size of the food being cooked. Since the height of the plate holder can be adjusted as desired, it is very easy to use and can be provided as a convenient cooking device.
