Description

[Detailed Description of the Invention] The present invention relates to a cylinder cooling prevention device for a cylinder built-in gas appliance.

An object of the present invention is to provide an apparatus that can prevent insufficient gas supply by cooling a cylinder using heat generated by a burner.

For this purpose, the inventor developed a cooling prevention device that uses steam as a medium (Utility Model Publication No. 57-3121), but it is not very effective, especially in the early stages, and the high pressure of steam tends to cause failures in the connections. occured.

As a result, they found that it is more effective to heat and circulate liquid instead of steam.

If it is not boiled, no steam will be generated, but if it is a liquid itself, it will exchange heat with the cylinder depending on the degree of heating, and it was through this trial that we came up with the idea.

Another advantage of liquids is that they have a smaller coefficient of expansion than gases and less pressure difference.

The present invention was completed under these circumstances, and its gist is that a liquid storage chamber 2 is formed around a gas burner 1, and a contact warmer 5 for a cylinder B is installed in a cylinder storage section 4 provided in a device body 3. The liquid storage chamber 2 and the contact warmer 5 are connected through communication pipes 6 and 7, and the communication path from the liquid storage chamber 2 to the communication pipe 6.7 and the contact warmer 5 is filled with liquid. This is a cylinder cooling prevention device in a cylinder built-in gas appliance, which is characterized by the following.

The contact warmer 5 in this embodiment has not only a flat arc-shaped chamber as shown in FIG. Press Kai-type plate 9.10
Alternatively, the metal serpentine tube 11 may be formed integrally with the connecting tube 6.7 as shown in FIG. 5).

In this case, the liquid storage chamber 2 is also spirally shaped.

In the figure, 12 indicates a cock. As described above, in this invention, the water, oil, etc. filled in the communication path is heated by the heat generated from the burner, and although the rate of increase in temperature varies depending on the type of liquid, it is gradually heated, and as a result, even if it is slightly When the temperature rises, convection occurs and reaches the contact warmer 5 via the communication pipe 6, warming the cylinder B, and the cooled liquid flow is returned to the liquid storage chamber 2 from the communication pipe 7.

Therefore, not only can the cylinder be prevented from being cooled by latent heat due to its use, but also the action starts quickly compared to heating with steam, and since the temperature is initially low, the action is not sudden and the gas This has the effect of allowing smooth use without causing problems such as sudden changes in the delivery amount.

As mentioned above, the heating effect of the present invention starts from the time the burner is ignited, and the temperature gradually increases, so there is no danger of the cylinder being heated rapidly and the flame suddenly growing as a result, as in the case of conventional methods. There is.
