Description

[Detailed Description of the Invention] The present invention relates to improving the thermal efficiency of a hot air bath device and reducing manufacturing and transportation costs.

In other words, conventional hot air bathrooms are made of wood, synthetic resin, or other highly insulating or low-permeable materials to create a hollow chamber, box, bag, or other hollow chamber that can be sealed, and a heat-generating stove or the like is placed inside to create a natural convection system. Since the bath is heated by radiation, the heat collects in the upper space of the closed room, and much of the heat is lost from the upper surface, and when the bather's head or upper body is hot, the lower body, such as the feet, is not warm, although the bather may feel stuffy. It was not possible to avoid this flaw. Therefore, in recent years, heat source devices such as circulating heating or blast heating that circulate heated air to average the temperature have been developed, increasing thermal efficiency and health benefits. Although these devices have become popular items, the heat source device is made as a separate unit and is detachable, which inevitably increases manufacturing and transportation costs.

The present invention improves the relationship between the heat source device and the constituent members of the hollow chamber body, simplifies the overall mechanism, and achieves economic effects such as reduced manufacturing and transportation costs, ease of handling for users, and thermal efficiency. The aim is to achieve the following:

Examples thereof will be described below with reference to the drawings.

Figure 1 is an overall external view of a disassembled hot air bath, including a partially cut-away section, and Figure 2 shows a vertical cross section of the chair on which the bather sits and the rear wall of the box body with its backrest.

That is, a seat 2 and a backrest 5 for a person to sit in a sealable hollow chamber assembled with a back wall 1, a bottom 3, an outer peripheral member 4, and an entrance/exit door 5 for the bather.
Set up A. Further, an electric fan 13 and an electric heating section 14 are arranged in the lower part of the rear wall so that the axis of the air blowing passage is perpendicular, and a heated air sending passage 15 in the vertical direction connected to the outlet thereof is built in. This heated air delivery channel 15 is formed in a horizontal direction between the seat 2 and the lower plate 7 so that one side communicates with the ventilation opening 8 located in the vertical direction opposite to the lower limbs of the seated bather. The air flow path 8A, and the other side are air blowing openings 9, 10, 11 that are angled into the backrest surface 5A, which is vertically provided in opposition to the back body at a height from the waist to approximately the shoulders of the seated bather. The rising air flow path is connected to the upper air flow path.

The air sucked in from the lower intake port 6 of the heat source device as shown by arrow A is heated by the electric heating section 14, passes through the heated air delivery channel 15, and is divided by the sliding guide 12, with one side being a horizontal air flow under the seat. One is from the air blowing opening 8 through the passage 8A as shown by arrow B, and the other is from the guide 17, 18 through the ascending air passage.
From the ventilation openings 9, 10, 11, arrow C, etc.
Divided into two parts, the bather's feet, lumbar vertebrae,
The hot air heats the back vertebrae first and then flows along the bather's body surface, heating it as it flows into the bathroom.

In other words, in a normal hot air bathroom, the entire sealed room is filled with hot air and the bather enters the room, so a large amount of thermal energy is required to heat the entire room, and the heat loss from the surface of the room is due to the internal temperature. This increases as the temperature rises, leading to wasted time and energy. However, with this invention, even if the sealed room is at room temperature, the hot air flow directly heats the bather's heat-generating parts such as the back, hips, and lower legs, so no waiting time is required and heat loss from the surface of the room body is reduced. The amount of energy consumed is extremely low, and a sufficient thermal effect can be obtained.

In the embodiment, the air flow path and the heat source device are built in the rear wall, but the structure housing the flow path and the heat source device may be separated from the rear wall of the hollow chamber and made into separate entities.
