Description

[Detailed Description of the Invention] [Field of Application] The present invention relates to a rice cooker, particularly a cabinet-type rice cooker for home use, and includes at least a rice cooker storage case (upper frame) that is removably provided in the cabinet. The present invention relates to a rice cooker in which the front opening of the cabinet is closed by a front plate connected to the front edge of the movable table, in which the rice cooker is supported by a movable table.

[Prior art and its problems] As a cabinet-type rice cooker, the one shown in FIG. 8 has already been proposed.

In this device, a movable table 1 is provided in a box body B so as to be pulled out, a rice cooking mechanism is provided on the movable table 1, a gas burner is exposed on the top surface of the movable table 1, and the gas burner and the rice cooker of the rice cooker are connected to each other. The upper frame 21 is placed so that the upper frame 21 is properly opposed to the upper frame 21. A front plate 11 is provided at the front edge of the movable table 1 to close the front opening of the box body B, and this front plate 11 is equipped with a handle for pulling out.

In this conventional device, when the movable table 1 is completely housed in the box body B, the front plate 11 closes the open part of the box body B, and rice cooking progresses in this state, and when not in use, The rice cooking mechanism section and the upper frame 21 are housed in the box body B. Therefore, unlike a normal rice cooker, the gas rice cooker is not always exposed on the top surface of the table or workbench. In other words, the gas rice cooker doesn't get in the way.

However, in the case of this conventional rice cooker, operability is insufficient.

The built-in part of the rice cooking mechanism of a conventional general gas rice cooker, that is, the lower frame 22, is housed in the movable table 1 as it is, and the operating parts such as the operating levers and operation buttons provided on the lower frame 22 are directly attached to the front plate 11. In cabinet-type rice cookers, which are often installed at a relatively low position because they are exposed at the bottom, the operation section is located at an extremely low position, making it difficult to operate when cooking rice.
This is because you have to bend your back a lot.

[Technical Problem] The present invention is designed to accommodate the moving table 1 in a drawable manner in the lower part of the box body B, and also to provide a large structure that closes the front opening of the box body B at the front edge of the moving table 1. In the case where the installation height of the appliance is low in a cabinet-type rice cooker in which the front plate 11 of the rice cooker is arranged in series, and the movable table 1 supports at least an upper frame 21 containing a built-in rice cooker. The technical challenge is to locate the operation part at a high position on the instrument in order to prevent the operability from deteriorating even when the instrument is used.

[Technical Means] The technical means of the present invention taken to solve the above-mentioned technical problems are as follows. A damper D whose upper end is swingably supported is suspended in the exhaust passage 4, and the downstream openings 13, 13 of the exhaust passage 4 are arranged above the front opening of the box body B. and said opening 1
Front plate 11 that closes the lower front opening of 3 and 13
An operation panel 6 electrically connected to the rice cooking mechanism of the rice cooker is disposed on the top of the rice cooker, and an operation section consisting of a start switch 51, a power switch, etc. is disposed on the operation panel 6.

[Effect] The above technical means works as follows.

Rice is cooked with the upper frame 21 placed on the movable table 1, but when the movable table 1 is pushed in, the front plate 11 is in line with the front edge of the box B, and the operation panel 6 is It is located on the top of the front plate 11. Therefore, when cooking rice, the rice cooker is put into operation by operating the operation section provided in the operation panel 6, and after the rice cooking is completed, the power can be turned off or the heat retention function can be turned off. can do.

Note that even if the rice cooker is placed below the counter or below the range, the operation panel will be located at the top of the rice cooker.

In addition, hot air and steam generated during rice cooking are forcibly discharged through the exhaust passage 4 built into the box body B, and are exhausted from the openings 13, 13 above the front opening of the box body B. After being exhausted, they escape upwards, so the negative effects of these exhausts do not reach the operating section below.

Further, during the rice cooking, the damper D in the exhaust passage 4 is opened by the wind pressure of the blowing fan 40, and thereby, hot air etc. during the rice cooking can be discharged. On the other hand, when the rice cooking operation is completed, the ventilation fan 4
When the rice cooker 0 stops, the exhaust passage 4 is blocked by the damper D, whereby the rice cooker housing space and the outside are thermally isolated.

[Effects] Since the present invention has the above configuration, it has the following unique effects.

Since the operation panel will be located at the top of the rice cooker, even if this appliance is installed in a low place, such as under a counter, the position of the operation panel will be relatively high, and the rice cooker will The operability is improved compared to the conventional one.

Since the hot air and steam generated inside are exhausted through the forced exhaust type exhaust passage 4, the rice cooker housed in the box body B can be smoothly exhausted, and this exhaust is also exhausted from the front of the appliance. There is no need to prepare a separate exhaust pipe etc.

Furthermore, although the operating section is disposed at the top of the door 11, the exhaust gas is discharged forward from above the door, so that the adverse effects of the exhaust gas on the operating section can be prevented. Therefore, the durability of the operating section containing various electrical devices is improved.

When the rice cooking operation is finished, the damper D blocks the exhaust passage 4 and thermally isolates the rice cooker housing space from the outside, making it difficult for the heat in the rice cooker housing space to be released to the outside when keeping the rice warm after cooking. , This suppresses a decrease in the heat retention effect.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 7.

The cabinet-type gas rice cooker of this embodiment is as follows:
It is designed to be built into a sink or counter, and as shown in Figs. 1 and 2, the rice cooking function part is a movable table 1 that is freely removable from a box body B.
The movable platform 1 is provided with a front plate 11 connected to its front edge for closing the front opening of the box body B, and the movable platform 1 is located at the bottom of the box body B. In order to make it possible to pull out the movable platform 1, rails 1 are provided on each of the opposing side walls of the movable platform 1.
The rail 10 is supported in a forward pair state by a support portion provided on the inner surface of the side wall of the box body B.

Opening 1 on the downstream side of the exhaust passage 4 at the upper end of the box body B
3 and 13 are located. This exhaust passage 4 is a duct attached to the ceiling inside the box body B. On the upstream side thereof, a cavity 42 for accommodating the ventilation fan 40 is formed, and on the front side of this cavity 42. The suction port 43 opens. This suction port 43 becomes the upstream open end of the exhaust passage 4. The position of the suction port 43 is opposite to the upper part of the upper frame 21 placed on the movable table 1.

The blower fan 40 is brought into conduction by closing the start switch of the rice cooking mechanism, and its operation is stopped by the operation of the automatic fire extinguisher.

Therefore, the blowing fan 40 is inserted into the electrical circuit shown in FIG. This electric circuit includes a solenoid valve 52 that is opened by a starter switch 51, an ignition device 53 that is in operation for a certain period of time, and a solenoid valve 52 that is opened by a starter switch 51;
2, a blower fan 40 connected in parallel to the electromagnetic valve 52, and a heat retaining device 55 which is a combination of a heater H and a thermostat 5.

Therefore, when the start switch 51 is closed, the electromagnetic valve 52 is opened to start supplying gas to the gas burner, and the ignition device 53 is operated to ignite the gas burner and start cooking rice.
The blowing fan 40 becomes operational.

When rice cooking is completed, the circuit to the electromagnetic valve 52 and the ventilation fan 40 is cut off by the operation of the heat-sensitive device 54, and these operations are stopped. At the same time, the circuit of the heat-retaining device 55 becomes conductive via the normally closed contact side of the heat-sensitive device 54, and henceforth, the heat-retaining device 55 maintains the temperature.

In the above embodiment, rice is cooked with the upper frame 21 placed on the movable table 1, but at the same time as the rice cooking starts, the ventilation fan 40 is activated, and the box B is placed in the exhaust passage 4. A flow of air is generated from the rear upper opening of the housing B, passing through the front edge of the upper end of the box body B and reaching the openings 13, 13.

Therefore, even if the intake opening area formed in the lower inner wall of the box body B is relatively small, sufficient air for combustion is sucked in by the forced suction action of the ventilation fan 40. Similarly, the combustion exhaust gas generated by the combustion of the gas burner is guided into the exhaust passage 4 by the forced suction action of the blowing fan 40. At this time, since the upstream end of the exhaust passage 4 is located at the rear upper part of the box body B, there is no fear that the suction air into the box body B will reach the upstream end of the exhaust passage 4 in a short circuit.

The combustion exhaust gas sucked into the exhaust passage 4 and the generated gas are discharged to the outside through the openings 13, 13 at the downstream end thereof.

When the rice cooking is completed, by the action of the control means,
Since the operation of the exhaust passage 4 is stopped, the forced intake and exhaust action is also stopped.

Originally, the number of openings for intake and exhaust is relatively small, so there is almost no visual convection when the rice cooking is completed.

The control for rice cooking and the control for keeping the rice warm are electrically operated, and in particular, in this embodiment, as shown in FIG. 5, the operation panel 6 is disposed on the upper part of the front plate 11. Therefore, operating means such as a start switch 51 and a power switch of the control device built in the upper frame 21 are arranged in the operation panel 6, and are electrically connected to the control device components of the rice cooking mechanism. ing.

This configuration further improves the operability of the rice cooker.

A handle 60 for pulling out the front plate 11 is arranged parallel to the operation panel 6 as shown in the same figure, and this handle 60 is built into the thickness of the front plate 11. Therefore, in this example,
There is no protruding member in front of the front plate 11.

Next, the thermal gas rice cooker with the above configuration basically has the same configuration as a normal household thermal gas rice cooker, but it houses a rice cooker and has an electric heat insulation function. The frame 21 is placed on the top surface of the movable platform 1, and the lower frame 22, which is equipped with a combustion device and an automatic fire extinguishing device, is mounted on the movable platform 1 with the exception of the operation section.
It is configured to be built in.

The moving table 1 includes, as shown in FIGS. 1 and 2,
So that the juice tray 23 of the lower frame 22 is exposed on the top surface,
The outer case of the lower frame 22 is housed, and this juice tray 2
The lower end portion of the upper frame 21 is fitted onto and placed on the upper frame 3. Thereby, the upper frame 21 and the lower frame 22 are integrated like a normal gas rice cooker.

The lower frame 22 moves together with the movable table 1, and in order to enable gas supply to the lower frame 22, the gas pipe G fixed to a part of the box body B is made of a bendable material. For example, a heat-resistant rubber tube or a flexible metal tube is used.

As the upper frame 21, that of a normal gas rice cooker can be used as is, but in this embodiment, a cylindrical protective cover 3 with an opening corresponding to the soup tray 23 is provided on the upper surface of the movable table 1. It is removably attached. As shown in FIG. 3, this protective cover 3 is composed of a rectangular top plate 31 and a pair of side plates 32, 32 extending downward from opposite sides of the rectangular top plate 31. An opening 33 having a size to fit is provided, and the peripheral wall of this opening 33 has a tapered shape that decreases downward.

In particular, the upper frame 21 is equipped with an electric heat retaining device, and as shown in FIG. 4, a cord reel 24 is provided on the upper part of the peripheral wall of the upper frame 21. Therefore, a partial concave portion 34 is formed in the peripheral wall of the opening 33 in a portion corresponding to the cord reel 24.

This protective cover 3 is attached so that one side sandwiched between the side plates 32, 32 is in contact with the rear surface of the moving platform 1. In order to make this protective cover 3 removable, Move the lower part 1
It is screwed to the upper part of the side wall with decorative screws N and N. A power outlet 25 is provided near the concave portion 34 of the side plate 32. Therefore, when the upper frame 21 is inserted through the opening 33, fitted and placed at a predetermined position on the moving platform 1, and the power plug of the cord reel 24 is connected to the outlet 25, the heat retaining device 55 in the upper frame 21 is activated. Becomes conductive.

The receptacle 25 is attached to a mounting bracket 26 on the top surface of the moving table 1, and the receptacle is attached so that the connection end surface is exposed directly from the receptacle opening 35 formed on the upper surface of the protective cover 3, as shown in FIG. 25 mounting positions are set. Therefore, when the plug of the cord reel 24 is removed from the outlet 25, the protective cover 3 can be taken out by removing the decorative screws N, N.

Further, in the above embodiment, the protective cover 3 is attached to the movable table 1 by screws, but it is also possible to make the protective cover 3 removable by fitting.

Furthermore, as shown in FIG.
If a damper D that is opened by zero wind pressure is provided in the exhaust passage 4, natural convection during heat retention will be eliminated, and the heat retention effect will be further improved.

Next, the second embodiment shown in FIG. 7 is a cabinet-type rice cooker in which the rice cooking mechanism is fixed inside the box body B, and the movable table 1 is not equipped with the rice cooking mechanism. be.

In this embodiment, the rice cooking mechanism section and the front plate 11
For electrical connection with the operation panel 6 of the
and the rice cooking mechanism fixed to the box body B are connected via an auxiliary cord reel 7, and the connection cord 71 of this auxiliary cord reel 7 is always urged in the retracting direction.

Therefore, a connection cord 71 is provided for electrical connection between the start switch 51 of the operation panel 6 provided on the front plate 11 and the rice cooking mechanism section provided at the bottom of the box body B.
is always applied with an appropriate tension, and there is no fear that this connection cord will become sagging and get caught on other nearby parts during the pull-out and push-in operations of the movable table 1.

Furthermore, in the case of this embodiment, the heat-sensitive device 54 facing the rice cooker is equipped to be able to move up and down, and a lifting device 56 is provided below this heat-sensitive device to drive it up and down. In a state separated from the box B, the lifting device 56 operates to pull down the heat sensitive device 54.
Therefore, when the moving table 1 is pushed in,
A micro switch 57 is disposed at a position facing the back surface of the front plate 11, and its actuator is connected to the front plate 11.
It is designed to be in contact with the back side of the This micro switch 57 is inserted in series in the circuit of the lifting device 56, as shown by the imaginary line in FIG. This micro switch 57 is normally in a closed state, and is closed when the front plate 11 separates from the box body B. When the front plate 11 closes the box body B, it is in the closed state. Therefore, in this box-closed state, the elevating device 56 is inactive, and the heat-sensitive device 54 is brought into contact with the bottom of the rice cooker by the biasing force of the biasing means applied to the heat-sensitive device 54. It will be done. Conversely, when the front plate 11 is separated from the box body B, the heat-sensitive device 54 is lowered by a certain stroke, and the movable table 1 can be pulled out.
