Abstract

PURPOSE:To prevent dicharging spark completely and facilitate cleaning by a method wherein a protecting body made of ceramic is fixed to the part which a metallic drip tray main body contacts with the wall of a heating chamber and the whole drip tray main body containing the protecting body thereof is coated with enamel. CONSTITUTION:The section of the protecting body 14 made of ceramic is almost 6-shape and the width D of the protecting body 14 is a little smaller than the total sum of intervals d1, d2 and the width d5 of the first vertical piece 17, accordingly, after protecting body 14 inserted into the first vertical piece 17 up to abut against the tip end 16a of the vertical side surface 16 through the second vertical piece 18 and the tip end 18 of the second vertical piece 18 is bent a little upward whereby the stopper of the protecting 14 is formed, and it is fixed to the drip tray main body 13. All of the protecting bodies are fixed to the drip tray main body 13 in the same method, thereafter, the whole drip main body 13 contained the protecting body 14 are applied with enamel coating to heat and to calcine whereby the enamelling drip tray 15 may be formed.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a metal saucer used in a heating chamber of a microwave oven.

(b) Prior Art Since this type of saucer is made of metal, it is necessary to take measures against discharge sparks that may occur at the contact portion with the wall of the heating chamber of the microwave oven.

FIG. 3 shows the prior art, in which metal trays ( 3) is multiplied.

FIG. 4 shows another conventional technique in which opposing protrusions are similarly provided on each of the left and right side walls (1) of the microwave oven heating chamber to form a tray (4), and the peripheral edge of the metal tray (3) is The tray (3) is held in the space by attaching a protector (5) made of an insulating material to the two parts and hanging it on the tray (4).

In each of the above embodiments, an insulator is inserted between the heating chamber wall and the saucer, so that they do not come into direct contact with each other, thereby preventing the generation of discharge sparks. However, in the case of FIG. 5, there is a drawback that it is expensive. That is, saucer (3)
In order to stably load the tuL, it is necessary to extend the receiving shelf (2) in the depth direction of the heating chamber and use it as a slide guide for the receiving tray (3). Naυ
, the cost of materials will increase. Particularly in a microwave oven equipped with a heater that heats the atmosphere of the heating chamber, the receiving shelf (2) must be made of ceramics that can withstand high temperatures, which further increases the material cost. In the case of Fig. 4, if the receiving shelf (4) is extended in the depth direction of the heating chamber, the protective body (5) can be formed only partially, and therefore there is no problem in terms of material cost. 5) and saucer (3) makes it easy for boiling liquid to get into the gap.

When cleaning the saucer (3), it is difficult to remove.

As a simpler structure! ! As disclosed in Japanese Patent Publication No. 55-14691, it has been proposed to curl the edges of a metal saucer into a round shape and hang the outer edges on a tray (4) as shown in Figure 4. Even in this case, there is metal contact between the heating chamber wall and the saucer, so the generation of discharge sparks cannot be completely suppressed, and even if the saucer is enameled and insulated.

Since the enamel film is thin, less than 200 μm, discharge sparks cannot be prevented.

Problems to be Solved by the Invention The present invention provides a metal saucer for a microwave oven that is inexpensive, completely prevents discharge sparks, and is easy to clean.

B) Means for Solving the Problems The microwave oven saucer of the present invention is a saucer used in the heating chamber of a microwave oven, and is made of ceramic at the portion of the metal saucer body that contacts the wall of the heating chamber. Fix the protective body made of
It is characterized in that the entire saucer body including the protector is enameled.

(E) Function According to the present invention, since the ceramic protector is interposed between the heating chamber wall and the metal saucer body, generation of discharge sparks between them is completely prevented, and the protector can be partially installed on the saucer body, so the material cost is not high.
In addition, since the entire saucer is enamel-coated, the saucer can be easily cleaned without allowing boiling liquid to get in between the protector and the saucer body.

(f) Embodiment FIG. 1A shows the saucer C1O of the embodiment of the present invention, and FIG. 1B
In this example, protrusions facing each other are provided on the left and right side walls (if) of the microwave oven heating chamber to form a receiving shelf a2, and a receiving tray α is placed on this receiving shelf.
It shows the state where C is multiplied. Note that the receiving shelf a3 is located in the depth direction of the heating chamber, and also serves as a slide guide for loading and unloading the receiving tray α.

Among the outer edges of the metal saucer body t13, ceramic protectors (141fi41) are fixed at two places in the front and back on both left and right edges (13a) and (13b) that contact the tray α2, and the saucer body including this protector The entire part 0 is enameled (C) as shown by the dotted line in the figure.

FIG. 2 shows the fixing structure of the protector I. The original left and right edges of the saucer body a3 are the vertical side surface 1e, and there is a space d on each side of the vertical side surface 1e.
f%d! The 1st stroke is formed by cutting down the IE2 vertical piece aηaa. The vertical side αe and the first and second vertical pieces (171α& are reeds on the same plane, and the respective tips (16
a) (17a) (18a) are bent inward at 90 degrees. Further, the tip ends (17a) and (18a) are at the same height, and the reed tip i1$ (16a) is lower than these.

The protective body (liFi) has a +16# shape in cross section and its vertical gap (14a) and horizontal gap (14b).

1st. It has a size that fits the second vertical piece a'naa.

Therefore, protector 0 is the first. The second vertical piece (171) can be inserted into the brocade.The tip (16a) of the vertical side surface 1L61 is.

It is arranged to abut against the horizontal side surface of the protector a4 in such an inserted state, and the width of the protector IO is slightly smaller than the sum of the above-mentioned intervals dl and d and the width dB of the first vertical side. Therefore, the protection body (14) is moved through the second vertical piece (1♂) until it abuts the tip (16a) of the vertical side surface (e) of the first ripple piece a?
), the tip (18a) of the second vertical piece a& is slightly bent upward (see Fig. 1B) to prevent the protector a4 from being removed, and it is fixed to the saucer body 0. be done.

After all the protectors are fixed to the saucer body a3 in the same way, a enamel glaze is applied to the entire saucer body 0 including these protectors α4, and heated and fired to make the saucer body a5.
! is formed. At this time, the protective body I and the saucer body α3 are completely integrated by the adhesive action of the enamel αS, so that the protective body α4 does not wobble, and the gap between the protective body a4 and the saucer body (13) Since the gap is filled with the enamel αS, the cooking liquid and the like will not enter into the gap, making it easier to clean the saucer.

In the above embodiment, four saucers were placed on the tray α2, but by extending the height of both edges of the tray α, the bottom surface of the tray body was also extended downward, and a similar protective body was provided at the lower end. ) It is also possible to place the saucer directly on the bottom wall of the heating chamber via a protector.

(G) Effects of the Invention According to the present invention, the generation of discharge sparks between the heating chamber wall and the metal saucer is completely prevented, the material cost of the protective body for this purpose does not increase, and Since the body is made of ceramic, the saucer of the present invention can be used.

It can also be used in a microwave oven with a heater.

The saucer can be easily cleaned despite the presence of the protective body.
