JPS5853892B2 - Heat plate for smoke generation in home smoker - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a hot plate for generating smoke in a domestic smoker.

Conventional household smokers include a method of using a corrugated hot plate and smoking in a gas range (Utility Model Publication No. 51-51984).
Since only the upper part of the heat source can be heated, there is an uneven temperature on the hot plate, and the wood pieces around the hot plate cannot be heated.

Another disadvantage is that a large heat source is required because a large amount of heat escapes from the heat source to the surroundings, resulting in poor thermal efficiency.

The present invention was made in view of the drawbacks of the conventional example, and
The first object of the present invention is to provide a heat plate for smoke generation in a household smoker that can increase thermal efficiency by providing fins on the heat plate and generate sufficient smoke with a small heat source. The purpose of 2 is to make the height of the fins gradually higher from the center of the heating plate toward the periphery, thereby making the temperature on the surface of the heating plate uniform, and making it possible to evenly pyrolyze the wood chips around the heating plate. To provide a hot plate for generating smoke in a vessel.

The present invention will be explained in detail below with reference to Examples.

As shown in FIG. 1, the smoke container 6 has a cylindrical shape with an open top, an air inflow hole 7 and a heat source storage port 14 at the bottom, and a cover 8 is removably attached to the top opening. This forms a smoker body 1.

This cover 8 is removable for removing the smoked object 12 and for cleaning the inside of the smoking container 6.

Further, a locking protrusion 9 is protruded from the upper part of the smoke container 6.
A net shelf 10 is installed on this locking protrusion 9, and a lift 11 is suspended from the net shelf 10.
The thing to be smoked 12 is placed on 1 or fixed with a hook.

A plate-shaped hot plate fixture 13 is provided at the bottom of the smoke container 6, and a hot plate insertion hole 15 is bored in the center of the hot plate fixture 13.

Legs 16 are provided protruding from the bottom of the smoking container 6.

The hot plate 4 has a large number of fins 5 hanging downward from a disk-shaped hot plate main body 17.

The shape of this fin 5 is as shown in FIG.
The gap 18 between the concentric and adjacent fins 5 is provided so as to face the fins 5 on the outer peripheral side.

Therefore, the gaps 18 between the fins located at the center, the gaps 18 between the fins in the second row, and the gaps 18 between the outermost fins are arranged in a staggered manner.

Further, the fins 5 which are vertically disposed from the hot plate main body 11 are formed so that the height gradually increases from the center toward the outer periphery.

The hot plate 4 is fitted into the hot plate insertion hole 15, and the fins 5 protrude downward from the hot plate insertion hole 15.

The heat source 2 is, for example, a box-shaped container formed in the shape of a bottomed cylinder with an open top, and an electric heater, for example, is attached to the lower surface of the bottom.

A gas burner, charcoal fire, etc. may be used instead of an electric heater.

This heat source 2 is placed directly below the hot plate 4 and is designed to heat the hot plate 4.

Therefore, when smoking with the household smoker formed as described above, the object to be smoked 12 such as fish or meat is placed on the net shelf 10 of the smoking container 6, and the smoking material 3 such as wood chips or wood powder is placed. is placed on the hot plate 4, the heater of the heat source 2 is turned on to heat the hot plate 4, and the smoke material 3 is thermally decomposed to generate smoke.

This smoke fills the smoker body 1 and smokes the object 12 to be smoked.

In this case, the high-temperature air that heats the hot plate 4 tries to escape to the surrounding area, but at this time the high-temperature air flows out through the gap 18 between the fins 5 as shown by the arrow in FIG. During this time, the amount of heat is efficiently absorbed by the hot plate 4.

As a result, sufficient smoke can be generated with a small heat source.

Further, to explain the temperature distribution of the high temperature air heated by the heat source 2 according to FIG. 4, the vertical axis indicates the temperature of the high temperature air, point C on the horizontal axis indicates the center of the hot plate 4, and D indicates the periphery. Show part.

The high temperature air is highest at the center of the hot plate 4 and becomes lower toward the periphery.

Therefore, if the height of the fins 5 increases toward the outer periphery, the fins 5 will absorb a large amount of heat toward the outer periphery, and the hot plate body will lose heat the most and will not be heated by high-temperature air. The temperature does not drop even at the edges of the hot plate 17, and as shown in FIG. 5, a substantially uniform heat distribution is obtained over the entire surface of the hot plate body 17.

As a result, the smoke material 3 is thermally decomposed uniformly from the center to the periphery, and there is an advantage that no unevenness occurs.

Next, another embodiment of the hot plate 4 will be explained according to FIG.
The hot plate body 17 has a container shape with an open top, and stores the smoking material 3 therein, and a lattice lid 19 is fitted from above.

In this case, the smoke material 3 will be heated from the surroundings and thermally decomposed more effectively, and the smoke will flow out through the grid holes 20 of the grid cover 19.

Claims (1)

[Claims] 1 A hot plate that generates smoke by heating smoking material such as wood chips or wood flour is placed on a heat source installed inside the smoker body, and a large number of fins are placed vertically toward the heat source from the hot plate. At the same time, the above-mentioned fins are arranged in a staggered manner, and the height of the fins gradually increases from the center to the periphery of the hot plate.
