[Industry use]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a temperature control device for a gas container in a gas appliance that uses a gas container detachably connected to a pressure regulator, transmits the heat of the combustion section to the gas container by a heat transfer plate, and heats it.

[Prior art]

Since the liquefied gas evaporates during use, the small gas container used for the portable gas stove lowers the temperature due to the latent heat of evaporation, and the combustion power decreases. As a countermeasure, heat of a combustion part (burner) is used for heating of a gas container by a heat pipe, a heat transfer plate, or the like. This method is effective in an environment where the temperature range of the gas stove is low, but for example, in case of bulgogi in summer, the temperature of the gas container is abnormally high, so the pressure sensing safety device is frequently operated, which is rather inconvenient.

[Problem to Solve Invention]

The present invention has been made in view of the above points, and the problem is that the temperature of the gas container is always adjusted to an appropriate temperature range regardless of the operating environment or the method of use, so as to reduce the fire power or operate the pressure sensing safety device. It is to be able to use the gas appliance properly without bringing inconvenience.

[Means for solving the problem]

The present invention for solving the above problems is provided with a pressure guiding means (12) for drawing the primary pressure of the gas before the pressure adjustment discharged from the gas container 10, and a slidable piston (21) and The pressure reducing means 22 receives a pressure reducing spring 22 having a predetermined spring force to pressurize it in one direction in the cylinder 23 to form a piston cylinder device 20, and pressurizes the piston 21 to resist the spring force. The other end of (12) is connected to the cylinder side, and the folding part 14 which can be contacted and spaced apart by a part of the heat exchanger circuit from the combustion part to the gas container 10 via the heat exchanger plate 13 is formed, 1 The means for providing the piston cylinder device 20 at the position where the fold part 14 is spaced apart by the piston 21 when the pressure difference exceeds the set value and the piston 21 slides is taken.

The heat generated in the combustion section is collected from the heat collecting section of one end of the heat transfer plate 13, passes through the heat transfer plate 13 of the heat transfer circuit, and reaches the gas container 10 at the other end of the heating section, thereby heating the gas container 10.

Now, when the internal pressure of the gas container 10 rises for some reason, since the primary pressure of the gas before the pressure adjustment is guided to the piston cylinder device 20 via the pressurizing means 12, the decompression spring 22 Above the set value of, the piston 21 starts sliding to space the fold portions 14 in the circuit components of the heat transfer circuit.

As a result, since the heating of the gas container 10 is stopped, the gas container 10 cools, and when the primary pressure decreases, the decompression spring 22 of the piston 21 overcomes and the gas container 10 comes into contact with the heat transfer plate. Warming resumes. Therefore, the temperature of the gas container 10 is always adjusted to an appropriate temperature range by repetition of cooling and heating.

EXAMPLE

1, 2 and 3 show Embodiment 1 of a gas container temperature regulating apparatus according to the present invention. This is an embodiment of the gas appliance A using the small gas container 10, which has a combustion section (burner) 15 on its upper surface and a storage chamber 16 of the gas container 10 inside its side. have. The heat transfer plate 13 collects combustion heat from one end of the heat collecting section 17 near the combustion section 13, and heats the gas container 10 from the heating section 18 of the other end. The heat transfer plate 13 is made of a metal or other plate-like material having good thermal conductivity.

The gas container 10 has a nozzle 19 for discharging gas at its tip, and when connected to a pressure regulator (so-called governor 11), the nozzle 19 is press-fitted by the check valve 29 to discharge the gas. The gas flows into the pressure regulator 11. The introduced gas is depressurized in a pressure adjusting chamber composed of a diaphragm or the like and is transferred to the combustion unit 15.

In order to take out the gas pressure before pressure adjustment (this is called primary pressure), the pressure outlet lla is formed in the position which passes through the primary pressure chamber l1b (refer FIG. 3). The taken out primary pressure is transferred by the pipe of the pushing means 12 to the piston cylinder device 20 to be described later.

In addition, the gas of the pressure (referred to as the secondary pressure) after flowing into the pressure adjusting chamber and depressurized in the primary pressure chamber l1b is passed through the mechanical field 28 in the gas passage 27 to the combustion unit 15. ), It becomes a combustible mixed gas and is ejected from the combustion port. The pressure regulator 11 may be equipped with a pressure sensing safety device, for example, the secondary pressure after depressurizing the gas discharged from the valve nozzle 19 in the pressure regulator 11 and the primary pressure before decompression. Is operated against the safety valve for opening and closing the gas passage of the secondary pressure, and when the primary pressure is abnormally elevated, the safety valve is moved to close the gas passage to the combustion section 15.

The piston cylinder device 20 accommodates the slidable piston 21 in the cylinder 23 so that the shaft portion 21a can protrude out of the cylinder 23, and reduces the pressure in the direction in which the piston 21 is immersed. (22) was worked (each figure is shown typically). The pressure reducing spring 22 pressurizes the piston 21 so that the shaft portion 21a does not protrude while the primary pressure is in the normal range, but when the primary pressure increases to a pressure exceeding the range, the piston 21 It is a spring of strength that is pressed and contracted. In FIG. 3, 12a represents a pressure port for introducing pressure into the cylinder from the pressure-inducing means 12, and 21b represents a sealing of the piston 21. As shown in FIG.

The folding part 14 is installed in a part of the heating circuit from the combustion part 15 to the gas container 10 via the heat collecting part 17, the heat transfer plate 15 main body, and the heating part 18. In the case of Example 1, the folding part 14 is comprised by the heating part 18 of the other end of the heat exchanger plate 13, and the gas container 10 mounted on the upper surface and making surface contact. In order to stop the heat transfer action by the piston 21 with respect to this folding part 14, the piston cylinder apparatus 20 is a position where the axial part 21a which is immersed in contact with the lower surface of the gas container 10 (heating part ( 18) is installed on the instrument body bottom plate 24 having the same surface height as that of 18). In Example 1, the attachment recessed part 25 is formed in the bottom plate, and the piston cylinder apparatus is fixed there.

Therefore, when the gas container 10 is at a high temperature and the primary pressure exceeds the set value and the piston cylinder device 20 is operated, the piston shaft portion 21a protrudes from the cylinder 23, and the rear surface of the gas container 10 is lowered. Since it pushes up (broken line of FIG. 2), the folding part 14 is in a spaced state. As a result, heat is hardly transmitted to the gas container 10 by the heating part 18. On the contrary, cooling of the gas container 10 starts by latent latent heat, and when the primary pressure is lowered, a dozen gas container ( 10) the seat is seated on the warming unit 18 so that the heating is resumed. The temperature of the gas container is controlled by the repeated heating and cooling.

Embodiment 2 of the apparatus of the present invention is shown in Figs. 4, 5 and 6, which divides the heat transfer plate 13 along the way, overlapping the divided end portions 13a and 13b and making the heat transferable contact possible. It is an example in which the folding part 14 which can be contacted and spaced apart is comprised by leaving in state (FIG. 6). In this case, the shaft portion 21a of the piston 21 presses one end (13b in FIG. 6) and is spaced apart from the other end (13a in FIG. 6), but the end portion (13b) of the pressurized side is opposite. It is made to contact elastically by its spring property (other spring is also possible) toward the edge part 13a.

Also in the second embodiment, the configuration of the piston cylinder device 20 may be the same as that of the first embodiment. Moreover, the copper apparatus 20 is attached to the heat shield plate 26 which partitions the combustion part 15 side and the storage chamber 16 side of the stove main body.

Therefore, when the gas container 10 is heated to a high temperature and the primary pressure is increased to overcome the decompression spring 22, the piston shaft portion 21a protrudes from the cylinder 23 to press the one end portions 13a and 13b. As the heat transfer plate itself is separated from the other side, and the function of transferring heat is lost, the gas container 10 is not warmed and is directed in a direction where the temperature is lowered by latent heat of evaporation. As a result, when the piston shaft portion 21a is immersed and the heat transfer plate 13 functions again, the heating of the gas container 10 is resumed, and the above operation is repeated as in the first embodiment.

7 and 8 show Example 3 of the apparatus of the present invention. The third embodiment is the same as the second embodiment in that the heat transfer plate 13 is divided in the middle, and the ends of the heat transfer plate are overlapped with each other so that the heat transfer plate 13 can be heat-transferred. In addition to the direction falling from 13b, under the normal pressure, the piston shaft part 21a of the piston cylinder apparatus 20 is made to press the heat-transfer plate edge part 13a to the other edge part 13b. Therefore, in the piston cylinder device 20, the pressure reducing spring 22 is assembled so that the primary pressure presses the shaft portion 21a in the protruding direction in the normal range, and the pressure port ( 12a is through a seal on the piston shaft 21a side.

Therefore, in the case of Example 3, the folding part 14 divides the middle part of the heat exchanger plate 13, superpose | polymerizes the cut | disconnected end parts 13a and 13b, and is made into the primary pressure which overcomes the pressure reduction spring 22. When the piston 21 slides, one end 13a is dropped from the other end 13b, and when the primary pressure is lowered again, the operation of polymerization of the both ends is repeated, and the temperature control of the gas container is repeated.

9, the fourth embodiment of the device of the present invention will be described. In this example, the piston 21 which senses the primary pressure is provided on the pressure regulator 11 side, and the heat transfer plate 13 is pushed down from the piston end to fall from the gas container 10. The heat transfer plate 13 is normally in a state in which it is possible to contact the lower surface of the gas container 10. When the primary pressure exceeds a set value, the heat transfer plate 13 is pressed downward by the piston 21 in the state in which the heat-receiving state is possible, and the lower surface of the gas container 10 is lowered. A gap is formed in the fold part 14 of the fruit. The pressure reducing spring 22 pressurizes the piston 21 in response to gas pressure. In addition, the heat-transfer plate 13 illustrated in conjunction with the operation of the lever 30 pressed by the shaft portion 21a at the tip of the piston 21. 31 represents an axial point of the lever 30.

In the fourth embodiment, the gas container 10 is supported by a support 32 not shown or shown in the drawing, and the gap 33 between the heat transfer plate 13 and the gas container 10 changes in size according to the change in the internal pressure of the container. By adjusting the amount of heat moving through the heat transfer plate (13). If both of the heat transfer plate 13 and the gas container 10 are completely in contact with each other, heat is directly transmitted. However, since there is a gap, heat is moved by radiation. Therefore, supplying the heat amount along the gap 33 to the gas container 10 by radiation has a very good effect in controlling the temperature of the gas container. The heat transfer plate 13 and the lever 30 are pressed by a spring or the like in the direction in which the heat transfer plate 13 is in contact with the gas container 10. In the fourth embodiment, the force guiding means 12 is a very short passage.

[Effects of the Invention]

Since the present invention is constructed and functioned as described above, when the internal pressure of the gas container 10 is increased, the piston cylinder device 20 automatically acts to stop the heating of the gas container 10 and the gas container by latent heat of evaporation. When the internal pressure of (10) decreases, the operation of the piston cylinder device 20 is stopped and the gas container 10 is heated. Therefore, the temperature of the gas container 10 can always be adjusted to an appropriate range regardless of the method of use. Therefore, the thermal power is not lowered or the gas container 10 becomes a high temperature, so that the pressure sensing safety device is not operated, resulting in an effect that the gas appliance can be used very comfortably and safely.
