Description

a dining stove

technical field

The utility model relates to an outer container of a dining furnace, more precisely, it relates to a technological structure of an outer container of a dining furnace.

Background technique

The dining stove mainly includes an inner tank and an outer tank. The outer tank of the dining furnace is filled with water, the inner tank is filled with food, and the inner tank is placed in the outer tank to contact with water. Heating the bottom of the outer tank raises the temperature of the water in the outer tank, indirectly heating and keeping the food in the inner tank warm. At present, more and more electromagnetic cookers are used for heating in the market. If the material of the outer tank is non-magnetic stainless steel, it is necessary to apply a bottom of magnetic material on the bottom of the outer tank. Most of the cooker heads of electromagnetic cookers are round. The shape of the bottom of the outer pot is also mostly round to match the round stove head, but when the dining stove and the outer pot are rectangular, it is unsightly to put a round bottom on the bottom of the outer pot, and it is very unsightly to put it on a flat table. Stablize. Although the patent No. CN201520012457.4 solves the above problems, as shown in Figure 1, during the manufacturing process, due to the high temperature generated at the bottom 2` during the bottom coating process, it is transmitted to the raised part 3`, and the edge ring area 1 of the bottom coating 2` `The temperature is also very high, and the shape in the ring area 1` is irregular and complex, resulting in inconsistent expansion and contraction in all directions. If the cooling speed is too fast, it will easily deform the bottom of the outer tank, which affects production efficiency and products. quality.

Utility model content

In order to overcome the disadvantages of the large difference in thermal expansion and contraction in various directions of the bottom coating structure of the above-mentioned dining stove outer container, the utility model provides a dining stove exterior that can reduce the difference in thermal expansion and cold contraction of the bottom coating structure in all directions. guts.

The process structure greatly reduces the degree of deformation of the outer tank in the manufacture of the outer tank, and improves the production efficiency and product quality.

The technical scheme that the utility model adopts is:

The outer container of the dining stove includes an outer container body and a base, the base is located at the center of the bottom of the outer container, and the bottom of the outer container is provided with several protrusions, and the protrusions surround the The base is evenly arranged around the center, and it is characterized in that: an annular protrusion is arranged between the base and the protrusion at the bottom of the outer tank. The cross-sectional shape of the annular protrusion may be an arc-shaped or non-arc-shaped special-shaped cross-section.

The annular protrusion can be closed or not.

Due to the different shapes of the bottom of different outer tanks and the different process conditions in the production process, it is obvious that the amount of deformation is also different everywhere. Use different cross-sectional shapes of annular protrusions and use closed or unclosed annular protrusions , After experiments and trial production, the best results can be achieved in the manufacture of production.

The ring-shaped protrusion near the bottom edge of the coating forms a local structure with a uniform cross-sectional shape, which is conducive to uniform heat conduction, makes the ring-shaped high-temperature zone evenly distributed, and the bottom structure of the outer tank is not suitable for deformation.

The beneficial effect of the utility model is embodied in that: it can reduce the thermal expansion and contraction differences in various directions of the bottom application structure during use, and reduce thermal deformation.

detailed description

Referring to Fig. 2, the outer container of the cooking stove described in the utility model includes an outer container body 1 and a bottom coating 2, and the bottom coating 2 is located at the center of the bottom of the outer container body 1, and the outer container 2 is The bottom is provided with a number of protrusions 3, and the protrusions 3 surround the base 2 and are evenly arranged around the center. It is characterized in that the base 2 and the protrusions at the bottom of the outer bladder Annular protrusions 4 are arranged between the protrusions 3 .

Referring to FIG. 3 , the cross-sectional shape of the annular protrusion 4 may be an arc 5 .

Referring to FIG. 4 , the cross-sectional shape of the annular protrusion 4 may be a rectangle 6 .

Referring to FIG. 5 , the cross-sectional shape of the annular protrusion 4 may be a trapezoid 7 .

Of course, the cross-sectional shape of the annular protrusion 4 can also be other special shapes.

Said annular protrusion 4 can be closed or not.

Due to the different shapes of the bottom of different outer tanks and the different process conditions in the production process, it is obvious that the amount of deformation is also different everywhere. Use different cross-sectional shapes of annular protrusions and use closed or unclosed annular protrusions , After experiments and trial production, the best results can be achieved in the manufacture of production.

The dining stove and the outer container can be rectangular or circular, and the outer container body is formed by stamping, and the bottom is circular, and the bottom is placed at the center of the bottom of the outer container and placed symmetrically around the bottom Four bumps.

The ring-shaped protrusion near the bottom edge of the coating forms a local structure with a uniform cross-sectional shape, which is conducive to uniform heat conduction, makes the ring-shaped high-temperature zone evenly distributed, and the bottom structure of the outer tank is not suitable for deformation.

The material of the outer tank is 304, 201 and other stainless steels, which have good high-temperature mechanical properties. The cross-sectional shape of the annular protrusion is obtained by pressure forming. It has a certain strength and can resist some thermal deformation.

The content described in the embodiments of this specification is only an enumeration of the realization forms of the utility model concept, and the protection scope of the present utility model should not be regarded as limited to the specific forms stated in the embodiments, such as the annular protrusion 4 can be is not closed.
