DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas appliance for adjusting the heating power of a gas burner to a desired heating power by manually operating a heating adjustment lever of a heating appliance for a gas appliance. The present invention relates to a gas appliance having a partition point for partitioning into a large thermal power range and a normal thermal power range.

[0002]

2. Description of the Related Art Conventionally, for example, a push-type ignition / extinguishing button of an ignition / extinguishing device for igniting and extinguishing a stove burner, and a thermal power adjusting device for adjusting the heating power of a stove burner are provided on an operation panel installed in front of a table stove. A slide-type thermal power adjustment lever of the device is provided. On the other hand, in the stove burner, for example, Chinese food has been required to be cooked deliciously at home. ). The heating power of the heating power adjustment device can be continuously adjusted within the range of the weak heating power and the strong heating power by manually operating the heating power adjustment lever to an arbitrary position in the horizontal direction. It has become.

[0003] As described above, when the heating power range is widened, the heating power of the stove is controlled within a wide heating power range of high calorie (high heat power, for example, 4600 kcal / h) and low calorie (low heat power, for example, 400 kcal / h). When performing the above, there is a problem that the fire is misfired by moving the wide heating power range at a stretch at a high speed by the manual operation of the heating power adjusting lever.

Therefore, in order to solve the problem, as shown in FIG. 9, an intermediate point between the strong heating position and the weak heating position of the heating power adjusting lever 101 on the side of the weak heating power relative to the middle heating power position (for example, as shown in FIG. 9). Stepped operation window 102 which lifts the heat adjustment lever 101 at 1300 kcal / h)
Is provided.

Thus, even if the user attempts to move the heating power adjustment lever 101 in a wide-ranging heating power range from the high heating power position to the low heating power position at a high speed in the squeezing direction at once, it is temporarily moved by the stop wall 103 provided in the stepped operation window 102. Is regulated, and thereafter, the heating power adjustment lever 101 is lifted and then moved again in the drawing direction, so that the above-mentioned misfire is prevented by narrowing the heating power range that can be quickly squeezed at a stretch. ing.

[0006]

However, in the above-mentioned stove, the outside diameter of a cooking pot generally used at home is usually less than 20 cm and the heating power used is 3200.
It is often kcal / h or less. In particular, for cooking in a general home, the heating power adjustment lever 101 is set to the medium heating power position (for example, 2
300 kcal / h) and low heating power (for example, 400 kcal
/ H) position. However, FIG.
As shown in FIG. 7, since the stop wall 103 is provided on the side of the low heating power position relative to the middle heating power position, the heating power adjustment lever 101 is provided.
In order to finely adjust the heating power of the stove burner by operating the heating power control lever 101, it is necessary to lift the heating power adjustment lever 101 as described above.

[0007] Also, due to an erroneous operation of the heating power adjustment lever 101, the normal use range (3200 kcal / h or less).
Therefore, it is not preferable from the viewpoint of disaster prevention that the fire easily switches to the high heat power side and a large flame rises unexpectedly. On the other hand, in a table stove, a mixture of fuel gas and combustion air is ignited by an ignition source such as a discharge spark. In order to perform this ignition smoothly and reliably, it is desirable that the heating power of the stove is set to a large heating power that is equal to or greater than the medium heating power during the ignition operation. However, if the heat at the time of ignition is too strong, the user may be inadvertently conceived, which is not preferable.

For this reason, in recent years, the heating power adjustment lever has been moved to a position (about 70% of the high heating power side of the heating power adjustment range of the high heating power and the low heating power) (higher heating power than the medium heating power) in conjunction with the ignition / extinguishing button. Let it be ignited. However, in the conventional table stove, the position of the heating power adjustment lever at the time of the ignition operation varies, and in particular, when it shifts to the high heating power side, there remains a problem that the user is inadvertently exposed as described above.

[0009]

The abolition wall on the low heat power position side compared to the conventional medium heat power position is abolished. Thereby, the heating power can be smoothly adjusted by operating the heating power adjustment knob 8 between the middle heating power position and the low heating power position which are generally used in the home, and the usability is improved.

At the time of the ignition operation of the stove burner 3,
When the heating power of the stove burner 3 is set near the strong heating power, the heating power adjustment knob 8 is moved rightward in conjunction with the ignition operation, and the extension piece 7a of the heating power adjustment lever 7 hits the stop wall B. By using the heating power of P as the heating power at the time of ignition, it is possible to prevent the rapid generation of the flame of the high heating power in the stove burner 3. Also, at the time of the ignition operation of the stove burner 3, when the heating power of the stove burner 3 is set near the low heating power,
The ignition is easily performed by moving the heating power adjustment knob 8 to the left in conjunction with the ignition operation and setting the heating power at the section point P where the extension piece 7a of the heating power adjustment lever 7 hits the stop wall C as the heating power at the time of ignition. Become.

In addition, regardless of the position of the heating power adjustment knob 8 and the heating power adjustment lever 7 before the ignition operation of the stove burner 3, the division point P (position of about 70% of the heating power adjustment range) is surely set. Therefore, the positions of the heating power adjustment knob 8 and the heating power adjustment lever 7 at the time of the ignition operation of the stove burner 3 do not vary, and reliable ignition and appropriate flame can be formed. Note that the extension piece 7a of the heating power adjustment lever 7 does not necessarily have to move to the stop walls B and C by the ignition operation. That is, the purpose can be achieved if the stop walls B and C function as limit values of the movement of the heating power adjustment lever 7 during the ignition operation.
