Abstract

PURPOSE:To improve the handling property and the comfortable property of a pit type foot warmer by a method wherein foot rests, accommodating a heater, are attached pivotably to the opening of a furnace box. CONSTITUTION:A pair of plate type foot rests 4, attached pivotably to both ends of the opening 2b of a furnace box 2, open and/or close the opening 2b of the furnace box 2 and retain the feet of an user with an arbitrary angle upon using them as a pit type foot warmer. On the other hand, a heater 6, accommodated in the foot rest 4, effects as a floor heating device under a condition that the foot rests have blockaded the opening 2b of the furnace box 2 while the same foot rest 4 acts as the auxiliary heating device of a main heater 7 provided in the furnace box 2 upon using it as the pit type foot warmer. According to this method, variation between the use as a sitting table type foot warmer and the use as the pit type foot warmer can be effected easily, the handling property is improved and, further, taking of never tired comfortable posture as well as delicate temperature regulation can be effected whereby the comfortable property of the foot warmer can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moat kotatsu in which a table is arranged on a furnace box formed by digging a floor surface.

[0002]

2. Description of the Prior Art As a moat kotatsu
As shown in No. 58, it is common to arrange a yagura on the furnace box, but recently, a so-called table-top moat kotatsu, which is a high-quality furniture-style table so that it can be used even in summer Demand is increasing. This type of moat kotatsu digs down a predetermined part of the floor surface F in a Japanese-style room, as shown in FIG.
A furnace box 2 for arranging an electric heater (not shown) is formed, and a table 1 is arranged on the furnace box 2. This furnace box 2 is used when it is not used as a moat kotatsu such as in summer. The cage 3 is fitted into the locking step portion 2a formed around the upper part of the floor so that the floor surface F is flat.

[0003]

In the above-mentioned conventional moat kotatsu, the cage used to close the upper surface of the furnace box is not used when the moat kotatsu is used, so it should be stored in a closet or the like. However, since the external dimensions are large, it is difficult to secure a storage space in a bulky and narrow residential environment. In addition, since the child of this cage is not always used,
It is often trapped in the inner part of a closet, and for this reason, when it comes to the stage where it is to be used, it has to be searched for each time and taken out from the storage place, which is very troublesome.

Further, in the conventional moat kotatsu, the depth of the furnace is
Since it is set according to the physique of general adults, it is too deep for old people and children, and when sitting for a long time, the burden on the hips and hips becomes large and there is a problem that it is easy to get tired.

Furthermore, in the conventional moat kotatsu, since the heater inside the furnace box warms the air inside the furnace box,
In particular, when it is used for floor heating by using a cage, there is a problem that much energy is wasted and it is difficult to finely control the temperature. An object of the present invention is to solve the problems that these conventional moat kotatsu have.

[0006]

SUMMARY OF THE INVENTION In the present invention, a pair of plate-shaped footrests containing heaters are rotatably attached to both ends of an opening of a furnace box in which a main heater is arranged. Solved.

[0007]

The pair of plate-shaped leg mounts rotatably attached to both ends of the opening of the furnace box opens and closes the opening of the furnace box, and also supports the user's legs when used as a moat kotatsu. It is held at an arbitrary angle. In addition, the heater installed in the footrest acts as a floor heating device when the opening of the furnace box is closed, and when used as a moat kotatsu, the heater of the main heater installed in the furnace box is used. It functions as an auxiliary heating device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings. First, FIG. 1, FIG. 2, and FIG. 3 are simplified cross-sectional views showing respective usage states of the moat kotatsu of the present invention.
As shown in the figure, the moat kotatsu of the present invention, like the conventional moat kotatsu, digs down a predetermined portion of the floor surface F of the tatami room to form the furnace box 2 for housing the main heater 7 serving as a heating source. Although the table 1 is arranged on the upper side, in the present invention, plate-like leg rests 4 and 4 can be respectively rotated by shafts 5 and 5 at both ends of the opening 2b of the furnace box 2. Is attached to.

The leg rest 4 is made of a material having thermal conductivity such as synthetic resin or metal, and as shown in the enlarged cross-sectional view of FIG. It has been incorporated. The heater 6 may be a plate-shaped panel heater or may be a plurality of sheathed heaters arranged in a row. Then, the leg rest 4 is rotated about the attached shaft 5 in a range of about 90 ° from a horizontal state to a vertical state in which a tip end thereof is located below, and a drive device (not shown). Is connected with.

The moat kotatsu of the present invention has the above-mentioned structure, and its function will be described below. First of all, when using it as a normal moat kotatsu, as shown in FIG.
It suffices to rotate each of the tips downward about the shafts 5 and 5 by a driving device (not shown) so as to contact the left and right wall surfaces of the furnace box 2, whereby the user lowers his legs downward. In this state, the legs can be put in the furnace box 2.
The inside is heated only by the heat of the main heater 7 installed inside,
It can be used as a normal moat kotatsu. Then, if the user wants to take a comfortable posture with the legs slightly extended from this state, the tip of the leg rest 4 may be rotated about the shaft 5 with its tip upward to any position. As a result, the user can sit with the legs extended as shown in FIG. 2, and fatigue is reduced. At the same time, when the heater 6 installed in the leg rest 4 is energized at this time, the leg rest 4 itself contacting the lower limbs is warmed, so that the main heater 7 keeps the heat in the furnace box 2 higher, and the heating effect is higher. In addition to being obtained, it becomes possible to warm energy saving without using the main heater 7 which consumes a large amount of electric power. Then, from this state, the footrest 4
When is rotated upward, the opening 2b of the furnace box 2
As shown in FIG. 1, it is closed by both leg mounts 4 and 4, and is substantially flush with the surrounding floor surface F where the moat kotatsu is provided. Therefore,
In this state, it can be used in the same manner as an ordinary table-type kotatsu, and the leg rest 4 can also be used as floor heating equipment.

As described above, in the moat kotatsu according to the present invention, the leg mounting base having the heater therein is rotatably attached to the opening of the furnace box so that the opening can be opened / closed and the legs can be held during use. At the same time, fine temperature control can be performed.

In the illustrated embodiment, the left and right leg mounts are rotated symmetrically, but the two leg mounts do not necessarily need to be symmetrically rotated and can be driven separately. It is more desirable that each user who faces the table can take his / her comfortable posture.

[0013]

As described above, in the moat kotatsu of the present invention, since the plate-like footrest containing the heater is attached to the opening of the furnace box so that the opening can be rotated and opened, the furnace It can be used as a normal table-top kotatsu with the top of the box closed, and can be easily changed when using a moat kotatsu to improve handleability, and also as floor heating equipment when the opening is closed. Will also be possible. Further, unlike the conventional one in which the opening is closed with a child cage, there is no need for a place to store the removed child cage, so there is no fear of narrowing the living space, and introduction into a narrow dwelling becomes easy. Furthermore, when using the moat kotatsu, the user's legs are held at an arbitrary angle and heated directly, so that you can take a comfortable posture without tired, and you can also finely adjust the temperature and improve comfort. At the same time, there are many excellent effects that energy can be saved.
