Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dish selection display for a high frequency cooking device equipped with an electric heater.

In high-frequency heating, the food itself absorbs high-frequency power,
The disadvantage is that it does not burn because it generates heat by itself. Also, if baking bread or other oven dishes does not work well, cooking with an electric heater is more effective.

The present invention relates to a high-frequency heating device in which an electric heater is provided in the heating chamber in order to improve this problem, and its purpose is to provide an easy-to-use device for first-time or unfamiliar users. It is intended to.

Microwave ovens can be used for cooking and reheating over high heat, thawing and stewing over low heat, and electric ovens can be used for making bread using the fermentation function and for cooking using the upper and lower heaters. The device is capable of handling more than nine types of cooking, such as browning oven dishes, grilling, etc., but when the user decides to use it, it is difficult to choose between the numerous timers and the numerous switch knobs. It was not easy to decide whether to do so. Also,
If there was only a selection switch between a microwave oven and an electric oven, it would be extremely difficult to select the knob after that, requiring skill.

In order to improve these drawbacks, the present invention first provides a switch (for example, the above-mentioned ~) for selecting the type of dish, thereby making it easier for the user.

An embodiment of the present invention will be described below with reference to the drawings.

In Figures 1 and 2, 1 is a heating chamber in which food 2 is placed and heated by high frequency heating or electric heater;
is a door that can be opened and closed at the front of the heating chamber, and 4 is heating chamber 1.
5 is a saucer on which food is placed; when used as a high-frequency heating device, it is made of heat-resistant glass or ceramics with low high-frequency loss; on the other hand, when used as an oven, the saucer is Generally, metal plates are used to provide heat conduction, particularly from the bottom surface in some way. 6
7 is a top electric heater, and 7 is a bottom electric heater.

In the high-frequency heating device with electric heater configured as described above, when cooking (above-mentioned ~), slide the knob 9 of the food type selection switch on the operation panel 8 to select ~.

Therefore, if you set the timer knob 10 to a predetermined time by referring to the cooking text according to the quality, quantity, and moisture content of the food, and then press the high-pressure application start button 11, the high-pressure application start instruction lamp 14 will be activated.
lights up, oscillates at high frequency, and after a predetermined period of time,
The timer goes to "0" or "off", and the application of high pressure ends and cooking ends.

In the case of an oven, set the gloss level 9 of the cooking selection switch to oven cooking, for example. Therefore, if the knob 12 of the selection switch for the upper and lower heaters is set to "upper or lower", for example, the upper heater 6 and the lower heater 7 are electrically coupled. At that time, the temperature is adjusted to a predetermined temperature using the knob 13 of the internal temperature control device depending on the type of food. After that, if you set a predetermined cooking time with the timer knob 10, oven cooking will start, the oven cooking start indicator lamp 16 will light up, and after the predetermined time has elapsed, the timer will turn off electrically.
Then, the cooking is finished.

Next, in the case of fermentation cooking, when making ``bread'' etc., ``yeast'' is fermented, but the temperature management at that time is controlled, and the temperature is kept at the optimum temperature.
If this is not done at the optimum time, the yeast may die, the bread may lose its shape due to over-fermenting, or the bread may become small and hard due to insufficient fermentation. Therefore, as shown in FIGS. 1 and 3, the following operating procedure was used.

First, turn knob 9 of the food selection switch to "fermentation," then turn knob 12 of the upper and lower heater type selection switch to "fermentation." Turn knob 13 of the internal temperature control device to "fermentation". Thereafter, a predetermined time is set using the timer knob 10. At this time, the indicator lamp 21 indicating that the "oven" is in use lights up. Then, after a predetermined period of time has elapsed, the timer is electrically turned off, and the "fermentation" ends.

A series of these tasks can be carried out by a skilled person.
You can easily operate the four operation knobs 9, 10, 12, and 13, but for first-time or inexperienced users, please read the instruction manual and follow each operation procedure. It was difficult to operate the knobs, and sometimes I would forget them, resulting in unsatisfactory dishes. Therefore, the present invention aims at "one-shot selection." That is,
The purpose is to operate the "fermentation" operation button on the operation panel 8 once, and then set the time using the timer. below,
An embodiment of the present invention will be described with reference to the drawings.

In FIG. 3, slide the knob 9 of the food type selection switch on the operation panel 8 to set it to "fermentation". Next, turn the timer knob 10 for the specified time.
Match at. Then, after the set time has elapsed, the timer turns off electrically and cooking ends.

Next, the circuit will be explained.

A conventional example is shown in FIGS. 4 and 5, and power is supplied to a power transformer 2 through a time switch 20, a contact 21a of a cooking type changeover switch 21, and door switches 22 and 23 that are linked to the opening and closing of the door.
Connect to 4. The high voltage secondary side of the power transformer 24 is connected to the magnetron 27 via a capacitor 25 and a diode A26, and oscillates radio waves when energized. The contact 21b side of the changeover switch 21 is connected to the heater output changeover switch 28, and its contact 21b side is connected to the heater output changeover switch 28.
8a is connected in series to the upper heater 29, to the diode B32 via one contact 31a of the upper and lower heater switches 31, to the upper heater, and to the temperature regulator 33 via the other contact 31b. . One contact 28b side of the heater changeover switch 28 is connected in series to the lower heater 30, and the other is connected to one contact 31c of the rotary type upper and lower heater switch 31, via a diode B32.
It is connected to the upper heater 29 and then to the temperature regulator 32.

Note that the rotary switch 31 in FIG. 4 indicates the "fermentation" state. That is, the lower heater 30
The upper heater 29 is connected in series with the upper heater 29, which is halved by the diode B32, so that overall power consumption is low and heating suitable for yeast fermentation can be performed. FIG. 5 shows the rotary switch 32
It shows the state of switching between the upper and lower heaters, and shows states such as "upper heater" only, "lower heater" only, and "upper and lower heaters used simultaneously". Let's compare these with the operation panel 5.

The knob 10 of the timer 20 is a switch for changing the type of cooking.The switches of the knob 9 are 21, 28.The door switch linked to the start button 11 is 22.
The knob of the temperature regulator 32 is 13, and the knob of the upper and lower heater selector switch 31 is 12.

(Some other circuits are omitted.) Next, one embodiment of the present invention will be described based on the drawings.

In FIG. 6, the "fermentation" circuit will be described.
The contact 6 side of the output selector switch 28 has the lower heater 30, rotary switch 43, contact c _p contact b,
The diode B32 is connected in series with the upper heater 29, and is connected to the fermentation temperature regulator 44 via the contact b side of the temperature regulator changeover switch 40.

Figure 7 shows the circuit for only the "upper heater".

From the contact b side of the output changeover switch 28, through the contact b side of the upper and lower heater changeover switch 42, to the contact d of the rotary switch 43, and the diode B32.
It is connected to the upper heater 29 whose power has been halved at , and is connected to the high temperature temperature regulator 41 via the a contact point of the temperature regulator changeover switch 40 .

Figure 8 shows the circuit for only the "lower heater".

Contact b of output selector switch 28, lower heater 3
0, the a contact of the heater up/down changeover switch 42, the a contact of the rotary switch 43, the a contact of the temperature regulator changeover switch 40, and the high temperature temperature regulator 41.

Figure 9 shows a circuit that uses both "upper and lower heaters" at the same time. One side from contact a of the output selector switch 28,
It is connected to the contact b of the upper and lower heater changeover switch 42, the contact point d of the rotary switch 43, the upper heater 29 halved by the diode B32, the contact a of the temperature controller changeover switch 40, and the high temperature temperature controller 41.

On the other hand, the high temperature temperature controller 41 is connected from the contact a of the output selector switch 28 to the lower heater 30, the contact a of the upper/lower heater selector switch 42, the contact a of the rotary switch 43, and the contact a of the temperature regulator selector switch 40. connected to.

Next, "grilled food" will be explained with reference to FIG. It is connected to the upper heater 29 as the b contact of the output changeover switch 28. At this time, the upper heater generates heat with twice the power consumption of the upper heater when the upper and lower heaters are used, and heats up the object to focus.

Next, the relationship with the operation panel 8 will be described.

When the food type selection switch 9 is set to fermentation, the output changeover switch 28 turns on contact b, and the rotary switch 43 contacts c and b are turned on.

Next, when a predetermined time is set with the timer knob 10, the contact 21 is turned on.

As mentioned above, there is no complexity in use, which is the drawback of having a two-stage electric oven or microwave oven, and it is easy to use, and does not require any skill even for inexperienced users. By having one unit, you can make effective use of kitchen space.
It becomes even more valuable.

Although a slide switch is used as the selection switch described above, it is not limited to a push button, rotary, drum type, etc.
