A collar provided on the upper side wall of the furnace engages with a protruding support edge on the inner surface of the upper side wall of the furnace box. The depth of the furnace is increased by sliding the lower side wall downward until its bottom reaches the bottom of the furnace box or until the bent edges engage and the lower side wall is suspended from the upper side wall. Make it deep.

b. When using the furnace box with a lower height Remove the upper side wall from above the lower side wall of the furnace box and use the furnace box with a lower height. In this case, the flange provided on the upper side wall of the furnace engages with a support edge protruding from the inner surface of the lower side wall of the furnace box.
The bottom and lower side walls of the furnace are raised relative to each other by the bottom of the furnace box, reducing the depth of the furnace.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

In Fig. 1, reference numeral 1 indicates a bottomed furnace box configured in the shape of a square in plan, and its side walls are divided vertically into two along the line A-A along all four sides, and the bottom 2 a lower side wall 3 that is integrated with the lower side wall 3; and an upper side wall 4 that is removably placed on the lower side wall 3.
A furnace rim 5 is further removably placed on the upper side wall portion 4. Engagement portions 6 and 7 are provided on the combined surfaces of the lower side wall portion 3 and the upper side wall portion 4 and the combined surface of the upper side wall portion 4 and the furnace rim 5, respectively, for use in positioning during stacking. The upper and lower engaging portions 6 and 7 have the same unevenness arrangement and size to form the lower side wall portion 3.
It is configured such that the hearth 5 can be positioned and placed directly on top of the furnace. A decorative window 8 punched out in a decorative shape for the purpose of ventilating the inside and outside of the furnace box 1 is formed on the lower side wall portion 3, and screw-type legs 9 are detachably attached to the four corners of the lower surface of the bottom portion 2. Further, support edges 10 and 11 that engage and support an upper edge flange 17 of the furnace 13 are protrudingly fixed to the inner surfaces of the upper and lower side walls 3 and 4, respectively.

A heat insulating material 12 is inserted inside the furnace box 1, and a furnace 13 made of a copper plate is further inserted inside the heat insulating material 12. The heat insulating material 12 is formed from a material such as asbestos or ceramics into a square shape so as to cover the surroundings of the furnace 13, and is placed on a furnace support 14 installed on the bottom surface of the furnace box 1. The side wall of the furnace 13 to be inserted inside this heat insulating material 12 is divided into upper and lower parts along all four sides, and a flange part 17 is formed on the upper edge inside the lower side wall part 15 that is integrated with the bottom part. The upper side wall portion 16 is slidably fitted in the vertical direction, and the lower side wall portion 15
J-shaped bent edges 18 and 19 that engage with each other are formed on the upper edge and the lower edge of the upper side wall portion 16 to prevent leakage of the ash 20 accommodated in the furnace 13. 21 indicates a trivet, and 22 indicates a pot.

The above-mentioned furnace is constructed from a state in which the upper side wall 4 is stacked on the lower side wall 3 of the furnace box 1 as shown in FIG.
Remove and change the height of furnace box 1 to 2 different heights,
Furthermore, it has a three-stage switching structure depending on whether legs 9 are attached or not, and the depth of the furnace 13 inserted into the furnace box 1 can be adjusted regardless of whether the furnace box 1 is used in two high or low positions. Since the structure can be changed, it is possible to provide a furnace that is easy to use and has an attractive appearance. Further, the following configurations can be added and changed to the above embodiment.

The main materials of the furnace, including the hearth box 1 and the hearth rim 15, are made of wood. For this reason, the surface of the wood is coated with lacquer such as Wajima lacquer to enhance the design effect. Wajima lacquer has excellent fire resistance, and this is utilized to simplify the structure of the heat insulating material 12. That is, in the above embodiment, when changing the height of the furnace box 1, two types of high and low square-shaped insulation materials 12 and 12' were prepared and replaced. You can simply lay down a sheet of insulation material.

In FIG. 1, in which the height of the furnace box 1 is set high, the entire furnace 13 with the upper edge flange 17 engaged with the support edge 11 is suspended by this engagement. As a result, the height of the furnace 13 can be changed depending on whether the furnace is used in two different ways. In this case, if the furnace support 14 becomes an obstacle, the furnace support 14 can be rotated around the fulcrum 0 as shown in FIG.
It is also possible to remove it from directly below 3.

[Effect of idea]

The present invention has the following effects. In other words, the side wall of the bottomed furnace box is divided into two parts, upper and lower, and the upper side wall is removably placed on top of the lower side wall, so the height of the furnace box can be adjusted depending on whether or not the upper side wall is used. It can be changed in two ways. In addition, the side wall of the bottomed furnace is divided into two parts, the lower side wall part and the upper side wall part are slidable in the vertical direction, and both side walls are provided with bent edges that engage with each other, and the upper side wall part is provided with a furnace box. Since the flange is detachably engaged with and supported by the support edge of the lower side wall or upper side wall of the furnace, the depth of the furnace can be changed according to changes in the height of the furnace box, making it easy to use. Moreover, it is possible to provide a fireplace that matches the atmosphere of a tea ceremony.
