Description

Description: FIELD OF THE INVENTION The present invention relates to a high-frequency heating device with a heater, and more particularly to a toast baking oven, generally called a toaster range.

2. Description of the Related Art In a conventional toaster range with a rotary mounting table shown in FIG. 3, for example, 14 is a heating chamber, 15 is a high frequency oscillator for supplying high frequency energy into the heating chamber 14, and 16 is a high frequency radio wave from the high frequency oscillator. Reference numeral 17 is a waveguide, and 17 is an upper heater in which a coil heater is covered with a crystallized glass tube. 18
Is a lower heater composed of a mica plate and a wire heater,
19 is a metallic rotary mounting table, and when baking toast or the like, a pan is placed on the baking table, so that the radiant heat from the lower heater 18 directly hits the bottom surface of the pan, the entire rotary mounting table 19 is It has a coarse mesh shape. 20 is a motor for driving the rotary mounting table 19 and 21 is a motor.
A rotary shaft for transmitting the rotary force from 20 to the rotary mounting table, and 22 for a roller.

The problem to be solved by the invention, however, in the conventional toaster range having such a configuration, since the food or the like is directly placed on the metal net-like rotary mounting table 19 and heated even at the time of high frequency heating, spillage of the food or the like occurs. If there is, the rotary mounting table 19 may become dirty, or it may be difficult to clean because it may pass through the mesh of the rotary mounting table 19 and spill onto the bottom surface of the heating chamber. Further, when the food contained in a metal container such as an aluminum container is heated at high frequency, there is a disadvantage that a spark is generated between the bottom surface of the metal container and the metal rotary mounting table.

The present invention is to solve such conventional problems,
It is an object of the present invention to provide a toaster range which is easy to use and has good performance both when heating a heater such as toast baking and at the time of high frequency heating.

Means for Solving the Problems To achieve the above object, the toaster range of the present invention is
The metal net-like rotary mounting table is enamel processed, and the borosilicate glass saucer is detachably provided on the rotary mounting table.When baking the toast, the glass saucer is taken out of the heating chamber and the rotary mounting table is used. Place the pan directly on top and heat with a heater. Also, for high frequency heating, use it for the glass saucer,
The food is put on it and cooked by heating.

Action The toaster range of the present invention is, during high-frequency heating, placed on a metal reticulated rotary mounting table in a heating chamber, a saucer made of borosilicate glass is placed thereon, and food or the like is further placed thereon for heating, for example, overheating. Therefore, even if the food is spilled, it will be accommodated in the saucer, so that the saucer can be washed without contaminating the rotary mounting table, the bottom of the heating chamber, etc., so that cleaning is not a problem. Furthermore, in the case of the toaster range, the bread is placed directly on the rotary mounting table and the toast is baked, so the cleanliness of the rotary mounting table is especially required, but the chances of dirt from spillage etc. are reduced. , Easy to care.

If it is only the above-mentioned thing, it means that a borosilicate glass plate for preventing spillage is simply added on the rotary mounting table of the conventional toaster range, but in the case of the present invention, it is not limited to that. Has the effect peculiar to the range. That is, the rotary mounting table is made of metal and has a mesh shape because the rotary mounting table to be used is made of metal and has a mesh shape in order to eliminate uneven heating during high frequency heating. It is intended to be used as a rack when heating the heater of
When the toast is baked, the coarser the mesh, the more radiant heat from the lower heater is not blocked, so the baking time can be shortened. However, during high-frequency heating, the coarser the mesh, the easier it is for radio waves to reach the rotary mounting table.
When the load is light, the rotary mounting table itself may be heated, and may become hot enough to cause a problem in handling. Due to the two contradictory facts as described above, the mesh size has conventionally been selected as appropriate. However, as in the present invention, when the borosilicate glass saucer is provided on the rotary mount during high-frequency heating, the borosilicate glass saucer itself becomes a load against radio waves, so even during light load heating, The heating by the radio wave to the transfer table itself is weakened, and the mesh roughness of the rotary table can be increased as compared with the conventional configuration. As a result, as a toaster range,
Bake time of toast can be shortened. Also, toast can have a burnt pattern according to the mesh pattern, but if this burnt pattern is a large grid pattern, it will be more toasty and the delicious toast that looks good will be baked. I have.

Embodiment Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, 1 is a heating chamber, 2 is a high frequency oscillator for supplying high frequency energy into the heating chamber 1, 3 is a waveguide for guiding the high frequency energy from the high frequency oscillator 2 into the heating chamber 1, and 4 is a coil heater. Is covered with a crystallized glass tube, 5 is a lower heater consisting of a flat heater composed of a mica plate and a wire heater, 6 is a metal rotary mounting table, and the surface is enamel processed. There is. 7 is a motor for driving the rotary mounting table 6, 8 is a rotary shaft for transmitting the rotational force of the drive motor 7 to the rotary mounting table 6,
Reference numeral 9 denotes a plurality of rollers rotatably fixed around the rotary mounting table 6. Reference numeral 10 is a borosilicate glass saucer according to the present invention, which has a round shape, and the protrusions 11 provided at several places around the rotary mounting table 6 and the outer circumference of the glass saucer 10 come into contact with each other, so that the glass saucer There are 10 positionings. Reference numeral 12 denotes an annular convex portion provided on the peripheral portion of the bottom surface of the glass tray 10, which is a device for removing peeling of the enamel processed on the surface of the rotary mounting table 6. Usually, when a dish is made of borosilicate glass, the back surface of the dish is textured and the surface is rough. The reason for this is that a ring-shaped pattern is formed at the time of molding, which is blurred, and one is to make small scratches and the like at the time of molding inconspicuous. It also includes the meaning of improving mold release and increasing productivity. For the reasons described above, the back surface of the glass saucer 10 is textured,
In the configuration of the present invention, the glass saucer 10 is used during high-frequency heating, but the glass saucer 10 is taken out of the heating chamber 1 and used during heater heating such as toast baking. Therefore, it is conceivable that the glass tray 10 is taken in and out several times a day, and the enamel on the surface of the rotary mounting table 6 is scraped off due to the rough surface of the glass tray 10 during long use. Therefore, in the present invention, the annular convex portion 12 is provided in the peripheral portion of the bottom surface of the glass saucer, the portion is in contact with the rotary mounting table 6, the surface of the portion is smoothed, and the other portion is textured as usual. In order to solve the above-mentioned problems, Further, as shown in FIG. 2, the rotary mounting table 13 is provided with the convex portion 12 not at the central portion but at the peripheral portion.
Has a net-like shape with a plurality of holes and is not a rigid body, so that it may slightly bend when heated, as shown by the chain double-dashed line in the figure. In this case, it is possible to prevent rattling of the glass tray by providing a convex portion, which is a portion that comes into contact with the rotary mounting table, in the peripheral portion where the amount of change in deflection is small.

Further, in the present invention, the rotating mounting table is subjected to enamel processing, because burr and the like are dangerous if the stamped parts of the press parts are left as they are, while the black enamel is used. This is because there is a slight heat storage effect, and in the case of toast baking, there is an effect that a net-like pattern hardly appears on the bread after the second time. For example, with a rotary mounting table that is made of stainless steel, no matter how many times the toast is baked, the cross-shaped bars always reflect heat, so the grid pattern of the bread will not disappear forever.

Effects of the Invention As described above, according to the toaster range of the present invention, the following effects can be obtained.

(1) Due to the configuration in which the borosilicate glass saucer is used at the time of high frequency heating, it is possible to obtain a large mesh roughness of the metallic reticulated rotary mounting table for the reason described above. Therefore, during toast baking, the radiant heat from the lower heater can reduce the amount of breakage due to the mesh bars, so that the toast baking time can be shortened.

(2) When baking the toast, the bread is placed directly on the rotary mounting table, so the rotary mounting table must always be kept clean. However, as in the present invention, the glass is heated during high frequency heating. By using the saucer, the spilled food does not directly stain the rotary mounting table as in the conventional case, and the cleaning can be maintained without washing the rotary mounting table, which facilitates the handling.

(3) In the case of the toaster range, since it is necessary to bake toast etc. in a short time, a coil heater covered with a crystallized glass tube that has a quick start-up is often used as the upper heater, but it is mistakenly used for high frequency heating. When heated by forgetting to sometimes load food etc., in the conventional case, the crystallized glass tube is heated, and if it is for a long time, it may lead to cracking of the crystallized glass tube, etc. By using the borosilicate glass pan as described above, the heating by high frequency is not concentrated on the crystallized glass tube, and the above problems are alleviated.

(4) Since the convex portion is provided in the peripheral portion of the bottom surface of the glass tray and the surface of the convex portion is made smooth, the friction between the convex portion of the glass tray and the rotary mounting table is reduced, and the enamel on the surface of the rotary mounting table is reduced. It became hard to be scraped.
