Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking microwave oven built into a dining table for home use.

BACKGROUND OF THE INVENTION Microwave ovens have gradually become more popular due to their speedy cooking, convenience, safety, and other features, and have become even more popular as microwave-specific foods have appeared in recent years.

In addition, as a dining table with a cooking function, there is a table called a cooking table, which has a gas stove or an electric stove embedded in the dining table.

Traditionally, household microwave ovens were
The tabletop type described in Publication No. 28 is the mainstream, and as shown in Figure 4, the door 2 provided on the side of the box l is opened, and the food to be cooked or the cooking container containing the food is inserted through this door. The configuration was such that cooking was performed with the door 2 closed.

Problems that the invention aims to solve However, we Japanese have many years of experience in cooking using stoves, and many of our dishes are suitable for this.Therefore, we cannot cook in a box like in an oven. This is due to the fact that it is difficult to stir the sea bream while cooking or to ``open the lid of the sea bream for a moment'' to check the doneness and taste.

To perform such an operation on a microwave oven, it is necessary to open the door and pull out the food inside, which poses the risk of overturning or spilling the hot food.

In addition, in recent years, as housing conditions have worsened, home kitchens have become smaller, and various cooking appliances must be installed or stored in a limited space. The current situation is that each household is having trouble placing it on top of their equipment.

As mentioned above, if the microwave oven is placed on top of other appliances, the height of the food being cooked will be higher, and the work of putting the food down on another table will be added, increasing the danger and creating false alarms. There were issues such as the food being cooked cooled down.

Even if the door of current microwave ovens were simply configured to open from above, the height would be too high to perform cooking operations from above, making it difficult to use and making it far from the stove-like feeling. Put it away.

In addition, the shoe king table is, for example,
There is one described in Publication No. 64. As shown in Figure 5, the stove unit A is buried in the center of the dining table top 3, but since the heat source becomes high temperature, it is dangerous to place food on the stove, so we solved this problem. To do this, we use measures to lower the height of the stove as much as possible. However, even with this, there was a problem that the danger of burns and fire due to the high temperature of the top plate 3 could not be completely eliminated. In addition, some devices incorporating electromagnetic cookers that utilize induction heating inside the dining table have become commercially available, but because the material and shape of the cooking container are limited, they are not yet common as cooking utensils and are not widely used in general-purpose stoves or microwave ovens. Still one step behind.

Therefore, the first purpose of the present invention is to incorporate a microwave oven into a dining table in the home, so that food can be inserted into the table and seasoning can be done from the top of the table. Not only can it be used for cooking, but it also eliminates the space required to install a microwave oven in the kitchen.

In addition, by opening the top door, the food to be cooked rises to the height of the table, making it easier to perform various operations during cooking, and making it easier to put in and take out food before cooking and at the end of cooking.
Furthermore, by lowering the cooking table with food on it to the bottom of the cabinet during cooking and rotating the cooking table, it is possible to easily visually check the cooking status from the top door, while heating the food. The second purpose is to eliminate unevenness.

Furthermore, a third object is to provide a control system that automatically opens and closes the door, raises and lowers food, rotates, and heats the food using a switch at hand.

Means for Solving the Problems In order to achieve the first object, the present invention embeds the cabinet of a microwave oven for storing and cooking cooked food, and has an opening/closing area for the microwave oven above the table. The configuration is such that

In addition, in order to achieve the second purpose, when the door installed on the top of the table is opened, the cooking surface on which the cooked food is placed becomes approximately the same height as the top surface of the table, and when the door is closed, the cooking surface A cooking table top and bottom drive unit that is lowered to the bottom of the oven body;
The rotary drive unit that rotates the cooking table is configured to have a rotary drive unit that rotates the cooking table.

Furthermore, in order to achieve the third objective, the control system of the table with a built-in microwave oven is equipped with a door opening/closing switch and a cooking on/off switch, and an opening/closing control unit that outputs a signal to the door opening/closing drive unit based on the signal from the opening/closing switch. , a vertical control unit that outputs a signal to the cooking table vertical drive unit to move the cooking table to the top when the door is open and to the bottom when it is closed, and a vertical control unit that outputs a signal to the cooking table vertical drive unit to move the cooking table to the top when the door is open and to the bottom when the door is closed. The structure includes a rotation control section that sends a signal to the rotation drive section to rotate the table, and a radio wave generation control section that drives the magnetron at this time to perform dielectric heating cooking.

Function: With the above structure, a home dining table and a microwave oven are integrated, and cooked food can be taken in and out from the top.

In addition, the cooking table vertical drive section that allows the cooking table on which cooked food is placed to be moved up and down lifts the cooked food to the same height as the table when cooking is stopped, and the rotary drive section that rotates the cooking table allows the cooking table to be moved up and down during cooking. Cook by rotating the stand at the bottom of the cabinet.

Furthermore, the control system of the table with built-in microwave oven allows
The function is to automatically perform a series of these operations using a switch.

Embodiments Hereinafter, embodiments of the present invention will be explained using FIGS. 1 to 3.

FIG. 1 is a perspective view showing the external appearance of a table with a built-in microwave oven according to the present invention. There is a microwave oven opening/closing door 4 in the center of the top plate 3 of the table, and when the door is closed, the top plate 3 is flat. It is designed to be. Further, the door 4 is provided with a window 5 through which the cooking status of the food inside can be checked.

6 is a control panel that will be explained later, which allows you to open and close the door, raise and lower the cooking table,
Instructs to start and stop cooking, etc.

FIG. 2 shows a sectional view of the main part, and a storage body 7 into which cooked food is inserted is embedded in the top plate 3. In Figure 2, the door 4 is shown in an open state.
Various methods can be considered, such as hiding inside. A cooking table 9 is built into the storage body 7 and moves up and down on which cooked food 8 is placed.
The cooking table 9 has a shaft 10 and a gear 1 which is a vertical drive unit.
1 and a motor 12 to move the cooked food up and down. Cooking table 9
As shown in the figure, the range in which the food is raised and lowered is such that the upper end is approximately at the same height as the top plate 3, and the food is exposed on the top plate, making it easy to check the cooking status and take out the food after cooking is complete. do. Further, the lower end is at a position 1 where the cooking table 9 almost touches the bottom of the storage body 7, as shown at 9' in the figure, and is in this position during cooking. Furthermore, when the cooking table 9 is cooking at the 9° position, radio waves generated by a magnetron (not shown) are introduced through the waveguide window 13. At this time, in order to prevent uneven cooking, the gear 14 of the rotation drive unit and It is configured to be rotated by a motor 15. 16 is a door opening/closing drive unit that opens and closes the door 4.

Here, a mechanism that uses the gears 11 and 14 or the motors 12 and 15 may be used. Also, the vertical drive section raises the cooking table 9 to the top of the top plate 3, and at that position, the rotary drive section drives the cooking table. It is also possible to easily rotate the food 9, and in this case, it becomes possible for everyone around the table to eat while eating the cooked food 8.

FIG. 3 shows a block diagram of this control system.

Reference numerals 17 and 18 are a door opening/closing switch and a cooking on/off switch built into the operation panel 6 shown in FIG. A door opening signal from the door opening/closing switch 17 is input to the opening/closing control section 19 . The opening/closing control section 20 outputs a signal to the opening/closing driving section 16 shown in FIG. 2 to drive the door 4 to open or close. Now, when the opening signal is input to the opening/closing control unit 20, the opening/closing drive unit 16 is driven in the direction to open the door 4. When the door 4 is in the fully open position, the opening/closing drive unit 16 outputs the full open signal a, and thereby the opening/closing control unit 20 stops outputting the drive signal of the opening/closing drive unit 16. In FIG. 3, this operation is equivalently represented by the contact 21, and the normally closed contact 2
1 is opened. The fully open signal a of the door 4 is also input to the cooking table vertical control section 22 at the same time, and this signal causes the gear 1 shown in FIG.
The cooking table 9 is moved upward by a cooking table vertical drive section 23 composed of a cooking table 1 and a motor 12. When the cooking table 9 reaches the highest point, the highest point signal is sent from the vertical drive unit 23 to the vertical control unit 2.
2 is output. This opens the normally closed contact 24 and stops the cooking table 9. At this time, the cooking table 9 is approximately at the same height as the table top 3.

When the door opening/closing switch 17 is operated to the door opening side, a closing signal is input to the upper and lower door sections 22, and the upper and lower drive sections 23 drive the cooking table 9 in the downward direction. When the cooking table 9 reaches the position 9' in FIG. 2, the vertical drive section 23 receives the lowest point signal C.
As a result, the normally closed contact 25 of the vertical control section 22 is turned off and the drive is stopped.

The lowest point signal C is simultaneously input manually to the door opening/closing control section 20,
This signal drives the opening/closing drive unit 16 in the direction in which the door 4 closes. When the door 4 is closed, the fully open point signal d turns off the normally closed contact 26 of the opening/closing control section 20 to stop the drive.

The fully closed signal d is simultaneously input to the AND logic section 27, which operates so that its output becomes positive logic only when all input signals are positive logic. If the
A rotary drive unit 29, which is made up of a gear 14 and a motor 15, shown at 8 in FIG. 2, operates to rotate the cooking table 9 to eliminate uneven cooking. The signal e is simultaneously input to the radio wave generator 30 and the interior light 31, and the radio wave generator 30 drives the magnetron 32 to generate electromagnetic waves at a frequency necessary for cooking and heat the cooked food. The interior light 31 is used to display the cooking status and to make it easy to check the cooking status through the window 5.

When the cooking on/off switch 18 outputs a cooking OFF signal, the AND logic section 27 stops outputting the output e and therefore stops the rotation of the cooking table 9, the operation of the magnetron 32, and the interior light 31. After this, when the door opening/closing switch 17 is operated to open the door, the door opens as described above and the cooked food is lifted.

If the door is opened during cooking, the door open signal of the door open/close switch 17 is inverted by the inverter (inverter) 3.
3, the signal is inverted and the A N D it processing section 27
Because of the input, the output e disappears, and the drive of the rotational drive unit 29, magnetron 32, and interior light 31 is stopped, and then the door is opened.

As described above, when closing the cooking table 9, the cooking table 9 is first lowered, and then the door is closed. If cooking is turned on when the door is closed, cooking starts, but if cooking is not turned on, the cooking table 9 remains on standby. Also, when you open the door,
If cooking is in progress, open the door 4 after stopping the cooking on the cooking table 9.
The operation is to raise the table to the height of the top plate 3.

In this embodiment, the cooking on/off switch 18 has been described as being configured to be operated manually, but it may also be configured to output a cooking off signal by a sensor such as a cooking timer or a temperature sensor. Further, the full open point signal a, the full closed point signal d of the opening/closing drive unit 16, or the highest point signal b1 and the lowest point signal C of the vertical drive unit 23 can easily be generated by using a rimming switch, but a displacement sensor, encoder, etc. You may apply
Furthermore, all of these functions may be configured by a microcomputer program.
The cooking table 9 may be configured to rotate even when the cooking switch is off, or the interior light 3 may be turned on even when the cooking switch is off.
Various sequences can be considered as necessary, such as allowing the light to turn on.

Effects of the Invention The table with a built-in microwave oven and the control system thereof according to the present invention described above have the following various effects.

(11) The cabinet of the microwave oven, which stores and cooks cooked food, is buried in the dining table, and an opening/closing door is provided on the top of the table.As the dining table and microwave oven are integrated, the home kitchen This eliminates the need for installation space for a microwave oven, allows the user to enjoy meals while cooking in the microwave, and eliminates the need to get up from the table to cook, leading to improved work efficiency for housewives and providing a place for family gatherings.

(2) Also, the progress of cooking can be easily checked from the top of the table, rather than from the side of the food as in conventional microwave ovens. Furthermore, since you can stir the food and add seasoning from the top, the cooking efficiency of the microwave oven is improved, almost the same as the conventional habit of ``opening the lid of the pot and checking the taste.''

Moreover, the food being cooked is under the table top.
Even children and the elderly can easily work from the top.

(3) The cooking table vertical drive section that allows the cooking table on which the cooked food is placed to be moved up and down lifts the cooked food to the same height as the table when cooking is stopped. Because the cooking table is rotated at the bottom of the cabinet for cooking, it is easy and safe to put in and take out cooked food.

In addition, it is possible to eat with the cooked food still on the raised cooking table, and the table top can be used efficiently.

(4) Furthermore, the control system of the table with a built-in microwave oven automatically performs a series of these operations using a switch, eliminating operational errors and improving safety and operability, and also making it easy to add an automatic cooking function. .

(5) Unlike a stove, a microwave oven has safety features such as the fact that the heat source reaches a high temperature during cooking, so there is no danger of burns, and even if a wooden table is used, there is no risk of fire. is high.
