Description

[Detailed Description of the Invention] The present invention relates to an electric cooker that allows roasting and steaming to be performed in the same room, and particularly relates to control of water supply for steam generation.

A detailed explanation will be given below using an example shown in the drawings.

1 is an inner box consisting of inner plates 2, 2 and a reflecting plate 3 which is integrally formed with a rear plate and a top plate, and the inside thereof is a roasting chamber 4, and upper and lower heaters are installed in the upper and lower portions of the roasting chamber 4. 5 and lower heater 6 are installed. Reference numeral 7 denotes an outer box formed by outer plates 8, 8, a rear plate (not shown), a top plate 9, and bottom plates 10, 11, and supporting legs 12, 12 are attached to the bottom of the outer box, and handles 13 are attached to the tops of both sides. , 13 are attached, and a shielding plate 14 for shielding heat from the inner box 1 is installed between the top plate of the inner box 1 and the top plate 9 of the outer box 7. 15,
15 is a guide rail with a U-shaped cross section attached to the inner wall of the inner box 1 to be located above the lower heater 6, and on the upper part of this lower piece, both side edges of the gridiron 16 can be attached/detached and slid back and forth. The tray 17 is placed on the upper part of the tray 17 so that both side edges of the saucer 17 can be attached and detached and slid back and forth. This saucer 17 receives water from a water supply tank, which will be described later, and receives water from the upper and lower heaters 5 and 6.
It acts to generate steam. Reference numeral 18 is a drainboard that is detachably installed on the upper part of the saucer 17, and has a large number of through holes 18a (small holes or long holes) formed on its upper surface, and the food 19 to be cooked such as chawanmushi is placed on the upper surface. It is becoming more and more common to 20
A drain plate is detachably provided at the bottom of the inner box 1 to store condensed water flowing down the front opening/closing door (not shown) and the inner wall surface of the inner box 1.

Reference numeral 21 denotes a water supply tank which is detachably installed on the upper part of the mounting board 22, and a cap 25 having a built-in valve 24 which opens and closes the valve hole 23 by vertical movement is detachably attached to the water supply port of the tank. Reference numeral 26 is a first operating lever whose midsection is supported by a pivot 27, one end of which faces the valve 24, and the other end supported by a return spring 28. 2
Reference numeral 9 designates a second actuating lever whose midsection is rotatably and swingably supported by a pivot 30 and a long hole 31, and one end of which is placed on the end of the first actuating lever 26 on the return spring support side. At the same time, the other end is bent downward and positioned above the timer device 32. The timer device 32 has a protruding pin 33 on its upper part that repeatedly moves up and down at regular intervals during timer operation, and a rotary shaft 34 that can be freely engaged and detached from the side edge of the bent piece 29a of the second operating lever 29. A cam 35 is provided.

A protruding pin 33 of this timer device 32 is provided below and facing the second operating lever 29, and is adapted to move upward for about 10 seconds, for example, every 3 minutes.
When the protruding pin 33 moves upward, the second actuating lever 2
9 is pushed up, the first operating lever 26 is rotated clockwise against the return spring 28, and the tip thereof moves the valve 24 upward to open the valve hole 23.
On the other hand, when the protruding pin 33 moves downward, the second operating lever 2
Since no pressing force is applied to 9, the first actuating lever 26
is rotated counterclockwise by the return spring 28, and the first operating lever 26 and the second operating lever 29 return to their predetermined positions. Of course, the valve 24 also moves downward under its own weight to close the valve hole 23.

Further, when the timer device 32 is operated, that is, when the rotary shaft 34 is rotated clockwise, the cam 35 engages the bent piece 29a of the second operating lever 29, as shown by the solid line in FIG.
does not prevent the second actuating lever 29 from being located above the protruding pin 33, but when the timer device 32 is turned off, that is, when the rotating shaft 34
When the cam 35 rotates counterclockwise, the cam 35 engages with the side edge of the bent piece 29a of the second operating lever 29, as shown by the two-dot chain line in FIG.
is slid in the A direction to prevent one end of the second operating lever 29 from facing the protruding pin 33 (as shown in the sixth figure). This is because the protruding pin 33 moves upward during the operation of the timer device 32 and the water tank 21
Even if the user forcibly rotates the rotary shaft 34 of the timer device 32 counterclockwise to stop the operation of the timer device 32 while water is being supplied from the This makes it possible to stop the water supply operation regardless of whether the water supply is running or not. That is, in the case of the timer device 32, the rotating shaft 3 is
4 forcibly rotated counterclockwise to stop the operation of the timer device 32 (“off” state), the protruding pin 33 remains in the upwardly moved state, and therefore the cam 35 If the engagement between the two-actuating lever 29 and the protruding pin 33 is not released, there will be a problem that the water supply operation will not be stopped no matter how long it takes. Furthermore, the second actuating lever 29 slides on the pivot 3.
It is needless to explain in detail that this is allowed because 0 is loosely fitted into the elongated hole 31.

Reference numeral 36 designates a rotating knob attached to the tip of the rotating shaft 34 of the timer device 32, and 37 designates a guide body for guiding water supplied from the water supply tank 21 to the saucer 17, which is connected to the outside of the roasting chamber 4. It penetrates the side wall of the inner box 1 and projects above the saucer 17. The tip of the guide body 37 is inclined downward toward the receiving tray 17 to smooth the water supply operation.

Here, the operation of the electric cooker of the present invention will be explained. First, in normal cooking for the purpose of roasting, the saucer 17 and drainboard 1 are placed from the top of the grill 16.
8 is removed and the food to be cooked is placed on the grill 16,
It is sufficient to energize the upper and lower heaters 5 and 6, and
By energizing the lower heaters 5 and 6, the food to be cooked is heated and cooked from the upper and lower parts.

Next, the case of steam cooking such as chawanmushi will be explained. When steam cooking such as chawanmushi, a saucer 17 is placed on the grill 16, and a drainboard 18 and the food 1 to be cooked such as chawanmushi are placed on the saucer 17.
9 is placed, and the upper and lower heaters 5 and 6 are energized. On the other hand, when the operating knob 36 is rotated clockwise, the cam 35 rotates together with the rotating shaft 34, and the second
The bent piece 29a of the actuation lever 29 and the cam 35 are disengaged, and the second actuation lever 29 is moved to the projecting pin 33.
The timer device 32 is driven.

The protruding pin 33 is driven by the timer device 32.
protrudes upward for 10 seconds at 3-minute intervals, and this protruding action rotates the first actuating lever 26 clockwise via the second actuating lever 29, causing the tip of the first actuating lever 26 to close the valve. 24 upward to open the valve hole 23. Therefore, only while the protruding pin 33 is moving upward (that is, for 10 seconds), water from the water tank 21 flows from the valve hole 23 through the guide body 37 to the saucer 1.
Supplied within 7 days. When the protruding pin 33 moves downward, the upward pressing force on the second operating lever 29 is released, so the first operating lever 26 is rotated counterclockwise by the return spring 28, and the valve 24 is opened. The valve hole 23 is moved downward by its own weight, and the valve hole 23 is closed, and the operation of supplying water from the water tank 21 to the saucer 17 is stopped. By repeating this operation, water is intermittently supplied to the saucer 17.

On the other hand, the temperature of the water supplied into the saucer 17 rises due to the influence of heat from the upper and lower heaters 5 and 6.
Eventually it reaches boiling temperature. The amount of water supplied into the saucer 17 at one time is relatively small since the protruding pin 33 of the timer device 32 is moving upward (for 10 seconds), and the rise time until the boiling temperature is reached is correspondingly short. shellfish.

When the water in the saucer 17 begins to boil, the steam passes through the through hole 18a of the drainboard 18 and enters the roasting chamber 4.
The food to be cooked 19 is steam-cooked.

Now, when the timer device 32 becomes "off" due to the passage of time or due to the user forcibly turning the operating knob 36 in the counterclockwise direction,
The cam 35 attached to the rotating shaft 34 pushes the bent piece 29a of the second operating lever 29 in the direction A, and moves the second operating lever 29 away from above the protruding pin 33 of the timer device 32. Therefore, even if the timer device 32 stops when the protrusion pin 33 is moving upward and the protrusion pin 33 remains in the upward movement state, the second operating lever 29 remains at a position away from the protrusion pin 33. Since the first actuating lever 26 returns to its original state due to the restoring force of the return spring 28, the valve 2
Release the pressure on 4. Therefore, the water supply operation can be reliably stopped at the same time as the timer device 32 is stopped.

In the above embodiment, water from the water supply tank 21 is supplied to the saucer 17 installed in the roasting chamber 4, and the saucer 17 is heated by the upper and lower heaters 5, 6 to generate steam and cool the roasting chamber. Although we have described a structure in which steam cooking is performed in the roasting chamber, a steam generator with a built-in heating heater is installed in the steam generation chamber, and steam is generated in advance outside the roasting chamber by this steam generator and then roasted. Of course, it can also be applied to a structure that leads into the firing chamber.

As described above, the present invention is an electric cooking device that has a roasting function that roasts and cooks food in the roasting chamber by energizing the heater, and a steaming function that steams water from the water tank and steams it in the roasting chamber. The container is equipped with a timer device that allows water to be supplied from the water tank via a lever device at regular intervals during steam cooking, reducing the amount of water supplied to the steam generating container at one time and reducing the rise time. It is very convenient because it can be done in a short time and steam can be generated effectively, and water can be automatically refilled into the steam generating container.The steam cooking time can also be arbitrarily selected using a timer device. It can have many remarkable effects.
