Description

[Detailed Description of the Invention] [Field of Application] The present invention relates to the structure of the lower frame of a gas rice cooker, particularly the structure of its operating section. Furthermore, by exposing the operating section from this portion, operability is improved and the configuration of the operating section is simplified.

[Prior art and its problems] In a gas rice cooker, an upper frame containing a rice cooker and a lid is placed on a lower frame consisting of a lower case containing a combustion device, an automatic fire extinguishing mechanism, etc. Adopt the configuration.

In this type of conventional gas rice cooker, an operating section is provided on the side surface of the lower case of the lower frame. Conventionally, this operating section has a configuration as shown in FIG. 3, in which an operating section lever 11 is projected from a lower case 1, and this operating lever 11 is surrounded by a decorative frame 12, whereby the operating section can be operated. A configuration is adopted that secures a space in the upward and return movement range of the lever 11.

The reason for protruding the operating lever 11 is to improve operability, and the decorative frame 12 prevents the inconvenience that the starting and returning operations of the operating lever 11 may be obstructed by objects placed near the operating lever 11. This is to prevent this.

However, with this conventional device, it becomes difficult to operate the operating lever 11 when the height of the lower frame is reduced.

This is because the decorative frame 12 surrounds the side and upper areas of the operating lever 11, and if the height of the lower frame is low, the frame portion of the decorative frame 12 located above the operating lever 11 and the initial the operating lever in the position
This is because, since the distance from the decorative frame 12 is particularly small, it is difficult to insert a finger inside the decorative frame 12 during a starting operation.

[Technical Issues] The present invention is designed to solve the following problems: ``The operation part is arranged on the side of the lower case 1 constituting the lower frame, and the upper frame A having a built-in rice cooker etc. is placed on the lower frame. In order to make it easier to operate the operation part even if the height of the lower frame is low in the "gas rice cooker", the operation lever 11 is
The technical objective is to make it possible to operate the lever without protruding greatly from the side of the lower case 1, and to secure a space for the upward and return movement area of the operating lever 11 without being surrounded by the decorative frame 12. Take it as a challenge.

[Technical Means] The technical means of the present invention taken to solve the above-mentioned technical problems is as follows: ``The lower case 1 is made into a hollow body with a downward opening, and the opening part is closed by the bottom plate 13. The outline of the side of case 1 is shown in upper frame A.
The wall surface of the shoulder of the lower case 1 is partially recessed to form a concave portion 2 that opens diagonally upward from the shoulder, and the concave portion 2 An opening 21 is formed therein, the operating portion of the operating lever 11 is exposed through the opening 21, and the outer shape of the lower case 1 is made to substantially match that of the lower end of the upper frame A.

[Operation] The above technical means of the present invention operates as follows.

When the upper frame A is placed on the upper surface of the lower case 1, the contour of the side part of the lower case 1 and the side part of the lower end of the upper frame A substantially match, so that the recessed part 2
A space having a triangular cross section is formed above the upper frame A and the bottom of the upper frame A. The operating lever 11 is exposed from an opening 21 that opens in the slope portion of this space (bottom wall of the recessed portion 2).

Therefore, when the operating portion of the operating lever 11 in this exposed state is pushed down, the gas rice cooker enters the operating state, and is maintained in this state thereafter.

Next, when the rice cooking is completed, the operation lever 11 is
moves back to the initial state (returns upward), and the upper part of this movement area is surrounded by the upper frame, and the peripheral area is surrounded by the peripheral wall of the recessed part 2. Therefore, articles installed near this area are difficult to enter into the moving area.

In addition, the above-mentioned space having a triangular cross section is located in the lower case 1.
Since it is constituted by the recessed part 2 directly formed in the upper frame A and the bottom wall of the upper frame A, there is no need to provide a special member for forming the space.

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

Without providing the decorative frame 12, the space formed by the bottom surface of the upper frame A and the recessed part 2 becomes a space for operation, so operability is improved even when the height of the lower frame is low. .

Further, since the decorative frame 12 as in the conventional device is not required to form the space, the configuration of the operating section is simplified and reduced in cost.

Furthermore, since the lower case 1 is a hollow body that opens downward, no gap is created around the recessed portion 2.
Therefore, there is no fear that boiling water will enter from around the concave portion 2.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

In the embodiment shown in FIG.
is one type of gas rice cooker, and the lower frame consists of a deep dish-shaped lower case 1 that opens downward, and a bottom plate 13 that closes this lower open end.
The gas burner B mounted on the top 3, an ignition system, an automatic fire extinguishing system, etc. are built-in.

Further, the lower case 1 is disk-shaped, and the upper surface thereof has a flame hole portion of a gas burner B protruding from a central opening as shown in FIG.

A stepped portion 15 for fitting and mounting the upper frame A is formed on the peripheral edge of the upper surface.

A part of the formation area of the stepped portion 15 is recessed into a spherical shape, and this becomes the recessed portion 2. Therefore, when the upper frame A is placed as shown in FIG.
An operation space will be formed between the two.

This recessed portion 2 has an opening 2 as shown in FIG.
1 is opened, but the periphery of this opening is an inward burring part 22 as shown in FIG. It will be protected.

Moreover, in order to place the upper frame A in a predetermined position, in this embodiment, the inner periphery of the stepped portion 15 is formed with an annular rib 16,
The bottom plate of the upper frame A has an annular recess 17 that fits therein.
has been formed. Therefore, when the upper frame A is placed, the concentricity between the lower case 1 and the upper frame A is maintained.

In the above embodiment, the case where there is only one operating lever 11 has been described, but it is also possible to have a configuration in which a plurality of operating levers are arranged in parallel in the opening 21.
