Description

[Detailed Description of the Invention] The present invention relates to a gas appliance, particularly a gas rice cooker equipped with a gas amount regulating device.

In order to cook various amounts of rice in the same gas rice cooker, set the gas combustion capacity J (hereinafter referred to as input) per unit time that is optimal for the amount of rice to be cooked, and also set the optimal amount of water at this time. Set the ratio (ratio of water amount to rice amount),
It is important to add an amount of water that matches the water amount ratio.

As a gas rice cooker that can perform such rice cooking, it is possible to selectively set in advance the optimal input that matches the rice amount classification, and also has several water volume scales corresponding to the rice volume classification, and sets the water volume scale according to the optimal input. Although we have proposed a method with a water volume scale when rice is cooked, in this case, from the viewpoint of ease of use, it is desirable to be able to set the optimal input that matches the amount of rice to be cooked and the water volume before starting rice cooking.

However, when performing the ignition operation according to the set number of inputs, it is difficult to adapt the same ignition device to variously varying inputs.

In other words, if the amount of gas to the ignition burner changes each time the input is set, the air and gas mixture state in the ignition burner will not be constant, and the amount of gas to the ignition burner will change in conjunction with the control section of the spark generator. In an ignition device that opens and closes a circuit and discharges electricity to an ignition burner at the same time, the ignition performance is extremely degraded in a gas amount range where the gas amount of the ignition burner is lower or higher than the standard gas amount.

Therefore, it is necessary to restrict the fluctuation range of the input of the ignition burner in the ignition device to as small as possible.

In addition, in a heat-retaining rice cooker, the input of the heat-retaining burner is extremely small, and if the input of the heat-retaining burner fluctuates to an excessively low level due to the optimum input setting, there is a strong possibility that a situation such as blowing out may occur. be.

The present invention was developed in view of the above points, and aims to improve the ignition performance of a gas rice cooker in which the gas amount can be adjusted over a wide range. .

The basic configuration of the present invention is that a gas amount adjustment device is provided separately from a valve device that is linked to an ignition spark generator, and an ignition burner and/or a heat retention burner are connected from the upstream side of the gas amount adjustment device. In addition, the gas circuit to the ignition burner is opened and closed by the valve device.

In the present invention, with the above configuration, the amount of gas to the ignition burner does not change due to the gas amount adjustment operation, and the ignition performance is improved over the entire gas amount adjustment range.

Hereinafter, embodiments of the present invention will be described based on the drawings.

In the figure, reference numeral 1 is a rice cooker, and on the inner surface of the rice cooker 1 there is an optimum water volume scale 2 engraved for cooking rice at the optimum input for each water volume category, and on the other hand, on the outer bottom surface. The thermal response device 3 responds to this, and when the internal temperature of the rice cooking pot 1 reaches the rice cooking completion temperature, the main burner 5 is extinguished by the valve device 4 interlocked with the thermal response device.

6 is a gas amount adjustment cock that adjusts the input of the main burner 5 in stages according to the amount of rice to be cooked.As shown in Fig. 2, an open hole 8 is bored on the downstream side of the shutter 7. A plurality of restriction holes 9, 9 are arranged radially to connect the hole portion 8 and the upstream side and appropriately restrict the flow rate to the main burner 5. The input of the main burner 5 can be optimally adapted to the amount of rice to be cooked by selectively communicating between the main burner 5 and the upstream side of the rice cooker.

Reference numeral 10 denotes an ignition burner, and 14 a heat retention burner, which are disposed near the main burner 5. Gas is supplied to the ignition burner and the heat retention burner by inserting the gas volume control plug 11 between the gas volume adjustment cap and the appliance plug 11. Opening/closing is controlled by a valve device 4.

During ignition operation, the valve element 13 is opened and closed in conjunction with the operating section of the high voltage generator that generates spark between the ignition plug 12 and the ignition burner 10, thereby blocking and communicating the gas flow path. be.

As described in detail above, the gas rice cooker according to the embodiment of the present invention has a gas amount adjustment mechanism that can selectively set the optimum input in accordance with the amount of rice to be cooked. Ignition burner 1 from the upstream side of the adjustment knob
Therefore, when performing the ignition operation after setting the optimum input that matches the amount of rice to be cooked, the ignition burner 10 will not be affected by fluctuations in the gas flow rate due to the optimum input setting. Therefore, fluctuations in the gas flow rate to the ignition device including the ignition burner 10 are only caused by fluctuations in the gas pressure introduced into the gas rice cooker, and the ignition performance of the ignition device is stabilized and improved. .

Furthermore, since the heat-retaining burner 14 is also connected to the upstream side of the gas volume adjustment valve, the flame of the heat-retaining burner is not affected by fluctuations in the gas flow rate caused by the optimum input adjustment (setting) by the cock.

Therefore, the flame of the heat retaining burner 14 is stable, and there is no fear that the flame will blow out due to insufficient input.

Since the present invention has the above configuration, it has the following dynamic effects.

(1) Since the gas amount can be adjusted before the ignition operation, rice cooking operations including the ignition operation can be performed after setting the input according to the amount of rice to be cooked, so the operating procedure is suitable for the rice cooker. .

(2) The operation of the gas amount adjustment device and the above-mentioned rice cooking operation (including ignition operation) are independent, and an interlock mechanism (safety mechanism) is required for a method that adjusts the gas amount after ignition and rice cooking. is no longer necessary, and the structure is simplified.

In addition, the gas flow rate adjustment device according to the embodiment of the present invention can be selectively switched between flow channels using a valve mechanism to sequentially change the gas flow rate of each flow channel, thereby setting the optimal input for each rice volume classification. Even if the gas flow rate adjustment device is replaced, the effect of the present invention remains the same.
