[0001]

[Industrial applications]

 The present invention relates to a cassette stove having a cassette cylinder.

[0002]

[Prior Art]

 Conventionally, the cassette stove is convenient to carry and suitable for use outdoors. Therefore, this cassette stove has a cassette type gas cylinder as a supply source of gas for combustion. In other words, this gas cylinder is detachably attached to the stove body and can be easily replaced. And, this gas cylinder has no means for displaying the remaining amount, and the stove body is not equipped with means for measuring the amount of gas used by the gas cylinder.

The gas cylinder was exchanged on the cassette stove as follows. For example, when the usage time of this gas cylinder is known, the usage time was compared with the usage time specified by the internal capacity, and the gas cylinder was replaced when it was used up to the usage time. Also, when the usage time of this cassette type gas cylinder was unknown, the gas cylinder was replaced after all the gas in this gas cylinder was used up.

[0004]

[Problems to be solved by the device]

 However, with the conventional cassette stove, it has been difficult to determine the remaining amount of gas in the gas cylinder when used by multiple users or when a long time has passed since the previous use. As a result, when using it outdoors, there was a problem that it was not possible to determine how many spare gas cylinders needed to be prepared. Moreover, since it is not possible to measure the amount of gas used depending on the type and content of cooking, there is a problem that it is difficult to judge whether a spare gas cylinder is needed or not, or how many gas cylinders are needed.

Therefore, the present invention provides a cassette stove in which it is easy to determine whether or not it is necessary to prepare a spare gas cylinder, and also to determine the number of gas cylinders to be prepared depending on the cooking content. Has an aim.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, in the cassette stove of the present invention, a stove body, a gas cylinder detachably provided to the stove body, a combustion member for burning gas supplied from the gas cylinder, A cassette stove that includes a thermoelectric generator that detects combustion by the combustion member and generates electric power, and a timer that operates by electric power from the thermoelectric generator.

[0007]

[Action]

 In the cassette stove configured as described above, the gas cylinder is attached to the stove body, and the combustion member burns the gas supplied from the gas cylinder. The thermoelectric generator detects the combustion of this gas to generate electric power and operates the timer with the electric power. As a result, the burning time can be measured by the timer. Therefore, the amount of gas used from the gas cylinder can be accurately known. Further, in this case, it is not necessary to provide the timer power source separately from the thermoelectric generator.

【Example】

 Hereinafter, an embodiment of a cassette stove according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an outline of a cassette stove according to an embodiment of the present invention.

As shown in FIG. 1, a cassette stove 1 according to the present invention is composed of a main body portion 2 and a cassette portion 3, and is formed in a box shape as a whole. At the four corners of the upper portion of the main body portion 2, there are installed a lot of pieces 12, 12, 12, 12 for supporting a kettle, a frying pan and the like. A burner 13 is fixedly provided in the center of the upper portion of the main body 2 so as to be surrounded by the above-mentioned members 12. An ignition device 15 and a thermoelectric generator 19 are fixedly installed near the burner 13, that is, in the vicinity of the gas outlet.

A cassette type gas cylinder 16 is detachably mounted inside the cassette unit 3. Gas is supplied from the gas cylinder 16 to the burner 13. A knob 14 for adjusting the flow rate of the gas supplied to the burner 13 is provided on the front surface of the cassette unit 3. A timer 18 is fixedly provided on the front surface of the main body 2. The timer 18 is configured to operate by the thermoelectromotive force from the thermoelectric generator 19.

The thermoelectric generator 19 is composed of a thermocouple in which a P-type semiconductor made of, for example, a FeSi ₂ compound and an N-type semiconductor are joined. Connect the hot contact side to the burner 13 and connect the reference contact side to both power supply terminals of the timer 18. Since the FeSi ₂ -based compound thermocouple has high oxidation resistance, it can operate as a stable thermocouple even at high temperatures. As the thermoelectric generator 19, a small thermoelectromotive force such as CC thermocouple (copper-constantan) or CA thermocouple (chromel-alumel) and a battery (for timer) may be used in combination. The timer 18 has a reset function (return to the initial state), and the timer 18 can be reset when the gas cylinder 16 is replaced.

Hereinafter, a method of using the cassette stove 1 will be described. When the frying pan is placed on the stove 12, 12, 12, 12 of the cassette stove 1 and the knob 14 is turned, gas is supplied from the gas cylinder 16 to the burner 13 and a spark is emitted from the igniter 15. The gas burns. At this time, the combustion power of the combustion gas is selected according to the cooking, and the amount of flame of the combustion gas emitted from the burner 13 is adjusted. At this time, the thermoelectric generator element 19 detects the heat of the flame and generates thermoelectromotive force. This thermoelectromotive force operates the timer 18. That is, when the heat of the combustion gas is transferred to the thermoelectric generator 19, a predetermined thermoelectromotive force is generated with respect to the temperature difference between the temperature of this gas and room temperature. This thermoelectromotive force applies a predetermined voltage to the timer 18, and the timer 18 can measure the heating time of the frying pan due to the combustion of the combustion gas.

Therefore, if the gas is burned after the cassette type gas cylinder 16 of the cassette stove 1 is replaced and the timer 16 is reset, the time when the gas cylinder 16 is used can be accurately measured. Therefore, the remaining amount of gas can be determined more accurately than the pressure gauge used in a fixed gas cylinder such as propane gas. When all the gas in the cylinder 16 is burned, the total usage time of the cylinder 16 can be automatically known. Moreover, since the time when the gas is burned can be measured, the remaining amount of the cylinder 16 can be predicted. In addition, it is possible to check whether there is a gas remaining amount according to the object to be cooked, and to provide a criterion for determining whether a spare cylinder is necessary or not. Further, since the operation of the timer 18 is performed by the power generation of the thermoelectric generator 19, a new power supply for the operation of the timer 18 is not required. In addition, the remaining amount of the cylinder 16 can be determined even if it is used by a plurality of people and the usage period is long.

[0014]

[Effect of the device]

 Since the present invention is configured as described above, it is possible to accurately measure the usage time of the gas cylinder. Therefore, it is easy to judge whether or not it is necessary to prepare a spare gas cylinder. Also, the number of gas cylinders to be prepared can be judged according to the cooking contents. Furthermore, it is not necessary to use a battery or the like as the power source of the timer, and the weight of the cassette stove itself is not significantly increased as compared with the conventional case.
