Abstract

PURPOSE:To provide the portable type kerosine stove capable of expediting ventilation by a ventilation alarm means after the set time of a timer has elapsed by a method wherein a thermal power generating element, generating an electromotive force by being heated by the exhaust gas of a combustion cylinder, is utilized to drive the timer. CONSTITUTION:The exhaust gas, discharged out of the combustion cylinder 11, rises up and flows into an exhaust gas guide tube 15 from an opening 14 immediately above the cylinder and is discharged to the upper outside of a cabinet through exhaust gas passing holes 3a, 3b,... of a ceiling plate 3. In this case, the high-temperature side terminals 18a of a multitude of thermal power generating elements 18, 18,... are heated heavily by high-temperature exhaust gas passing through the exhaust gas guide tube 15, while the low-temperature side terminals 18a are faced to an upper partitioning chamber 16 separated from a heat rays reflecting chamber 6, therefore, a temperature difference is increased to generate the electromotive force in the thermal power generating elements 18, 18,... and the motor of the timer 20 is driven by the power. When the set time 60min, for example, of the timer 20 has elapsed, a timer switch 21 is put ON to supply the electric power of the elements 18, 18,... to a buzzer 22 and the buzzer 22 sounds to notify that the ventilation is to be effected.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a portapu-type kerosene stove having a wick that can be moved up and down.

(B) Prior Art Conventionally, in a conventional portable kerosene stove with a wick that can move up and down, the exhaust gas from the combustion tube is directly discharged into the room, and the kerosene is burned using the room air as combustion air. If burned for a long time, the room would become depleted of oxygen, and if the room was not ventilated about once every 30 to 90 minutes, oxygen deficiency symptoms such as headaches and nausea could occur.

Therefore, in recent years, open-type hot air heaters have been proposed that detect oxygen concentration using an oxygen deficiency sensor and stop combustion, or turn on a ventilation notification lamp to encourage ventilation. In addition to having a complicated structure, conventional devices have problems in that they cannot be used unless a household AC power outlet is nearby and are portable, meaning they can be carried and used anywhere.

(c) Purpose of the Invention The present invention was made in view of the problems of the prior art mentioned above, and drives a timer by effectively using a thermoelectric element that is heated by the exhaust gas of the combustion tube and generates an electromotive force. The aim of the present invention is to provide a portable kerosene stove which can prompt ventilation by means of a ventilation alarm means after the timer has been activated for a set time.

B) Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a cabinet that forms a heat ray reflection chamber above the horizontal reflector, and a lamp wick that is arranged under the horizontal reflector and is movable vertically. A built-in fuel tank, a combustion tube placed above the fire pan of the fuel tank, the upper part of which passes through the horizontal reflecting plate and faces a heat ray reflection chamber, and a combustion tube located directly above the combustion tube. An exhaust gas guide tube, a large number of thermoelectric generating elements installed with the high temperature side end facing into the exhaust gas guide tube and the low temperature side end located in the upper compartment separated from the heat ray reflection chamber, The device is configured to include a timer driven by the electromotive force of the power generating element, and ventilation alarm means that issues a busy alarm after the set time of the timer.

When the minutes have passed, the timer switch (21) is turned on and power is supplied to the thermoelectric generator (IOK-) to the buzzer (A). Let me know.

Next time when heating is to be continued, K can notify the next ventilation by resetting the timer using the knob (c) again.

Although a motor-type timer is used in the embodiment of the present invention, the present invention is not limited to this, and an IC timer circuit may also be used.

(F) Effects of the Invention As described above, the kerosene stove of the present invention has an exhaust gas guide located directly above the combustion tube to direct the exhaust gas from the combustion tube whose upper part faces the heat ray reflection chamber through the horizontal reflector. External pressure is discharged through the cylinder, and the electromotive force of a large number of thermoelectric generators whose high-temperature side ends are respectively exposed to the exhaust gas guide cylinder drives a timer for activating the pressure ventilation alarm means after a set time. Therefore, if the device itself can generate electricity to promote ventilation, it can be carried around and used even in places where there is no power outlet nearby, and if it can maintain vertical pullability, it can improve the safety of the button at the same time. Furthermore, since the low-temperature side end of the thermoelectric generator installed in the exhaust gas guide tube is placed in the pressure part of the upper compartment separated from the heat ray reflection chamber, the temperature difference between both ends can be increased.
The electromotive force can be increased and the timer can be driven stably.
