Description

[Technical field]

[0001] The present invention relates to a sauna apparatus that is configured by disposing, within a sauna room, a heating device having a heat source function and a loyly function, and a waiting area where sauna users wait. [Background technology]

[0002] As an example of this type of sauna device, a sauna device as shown in Patent Document 1 has been proposed. This sauna device is configured with a sauna stove for heating and a waiting section in which sauna users wait inside the sauna room. The high-temperature air heated by the sauna stove increases the ambient temperature inside the sauna room. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3237499 Summary of the Invention [Problem to be solved by the invention]

[0005] In this type of sauna equipment, the high-temperature air heated by the heating device placed on the floor side is gradually pushed up to the top of the sauna room by buoyancy, and accumulates at the top of the sauna. Meanwhile, the high-temperature air that subsequently rises by buoyancy pushes down the air, causing the high-temperature air area to spread from the top of the sauna room to the bottom, heating the entire sauna room. However, since the speed at which this high-temperature air spreads from the top of the sauna room to the bottom is extremely slow, the temperature near the heads of users sitting in the waiting area, which is located near the ceiling wall of the sauna room, reaches a high temperature of 90 to 100°C, while the temperature in the area near the sauna user's feet at the bottom of the sauna room is low at 40 to 50°C, creating a large temperature gradient between the upper and lower areas and continuing for a long time.

[0007] As a result, the user sitting in the waiting area will experience excessively hot heads, dry eyes and noses, and skin irritation, resulting in an extremely uncomfortable state.

[0008] On the other hand, people sitting near the bottom of the sauna room are not warmed by the heat, so they are not comfortable. Moreover, if this low temperature continues for a long time, there is a risk of mold growth due to condensation on the floor, which is unhygienic.

[0009] For these reasons, there is a demand for this type of sauna equipment to have improved heating characteristics so that the large temperature gradient between the upper and lower areas of the sauna room can be quickly eliminated, as well as to improve thermal efficiency and reduce operating costs.

[0010] Therefore, in the process of considering solutions to the above-mentioned problems, the inventors of the present application came up with the idea of ​​making effective use of the heated air, rather than simply allowing all of the high-temperature air that is heated and rises to the top of the sauna room to remain at the top and be used in a random manner, by actively removing some of the heated air that rises due to buoyancy from the top of the sauna room and returning it to the middle or bottom of the sauna room to reuse the heat, and they propose a sauna apparatus that embodies this idea. [Means for solving the problem]

[0011] In the present invention, the following configuration is adopted as a specific means for solving the above problems.

[0012] In the first invention of the present application, a sauna room The floor is equipped with an electric heater and heat storage stone as a heating source. Heating device and 、 In a sauna apparatus having a waiting section where sauna users wait, The sauna room In the side wall close to the heating device The side wall is provided with an air passage extending vertically therethrough, and the air passage Top of teeth Facing the hot air inlet opening at the top of the sauna room The air passage in the wall Bottom edge of is the above Connected to one end of the in-floor ventilation passage installed inside the floor surface do On the other hand, in addition to the above-mentioned floor ventilation passages The edge on the floor of the sauna room andBelow the standby area formed in The air flow from the in-floor ventilation path side is opened facing the internal space. into the internal space. The internal space is formed of the above-mentioned part. The sauna room is connected to the inside space through the gap, and the air flow in the internal space is Flows into the sauna room to make The present invention is characterized in that it is configured as follows.

[0013] The second invention of the present application is characterized in that, in the sauna apparatus of the first invention, a first intake fan is provided within the internal space to introduce the air flow in the flow path from the intra-wall air passage to the intra-floor air passage into the internal space.

[0014] The third invention of the present application is characterized in that in the sauna apparatus of the first or second invention, a second intake fan is provided near one side of the floor surface and close to the entrance / exit door of the sauna room, for introducing the air flow in the in-floor air passage into the sauna room.

[0015] The fourth invention of the present application is characterized in that in the sauna apparatus of the first or second invention, an air flow collection and guide section is provided at a location directly above the heating device near the ceiling wall of the sauna room, which collects a portion of the air flow moving upward from the heating device and guides it to the high-temperature air inlet side.

[0016] The fifth invention of the present application is characterized in that, in the sauna apparatus of the first or second invention, the in-floor air passage is configured such that the upper surface of the flow path is composed of a plywood having a number of air vents and a stainless steel pan stacked on the upper surface of the plywood, and a portion of the air flow flowing through the in-floor air passage comes into contact with the stainless steel pan through the air vents in the plywood. Effect of the Invention

[0017] The present invention provides the following effects.

[0018] (a) In the first aspect of the present invention, a sauna room The floor is equipped with an electric heater and heat storage stone as a heating source. Heating device and 、In a sauna apparatus having a waiting section where sauna users wait, The sauna room In the side wall close to the heating device The side wall is provided with an air passage extending vertically therethrough, and the air passage Top of teeth Facing the hot air inlet opening at the top of the sauna room The air passage in the wall Bottom edge of is the above Connected to one end of the in-floor ventilation passage installed inside the floor surface do On the other hand, the other end of the above-mentioned in-floor ventilation passage on the floor of the sauna room and Below the standby area formed in The air flow from the in-floor ventilation path side is opened facing the internal space. into the internal space. The internal space is the waiting section. The sauna room is connected to the inside space through the gap, and the air flow in the internal space is Flows into the sauna room to make It is structured as follows.

[0019] With this configuration, a portion of the heated air blown up from the heating device toward the ceiling wall of the sauna room is introduced into the in-wall air passage from the high-temperature air inlet, and this air is introduced from the in-wall air passage through the in-floor air passage into the internal space, and from here it is blown out into the sauna room through the waiting section.This makes it possible for the atmospheric temperature in the area near the bottom of the sauna room to rise more quickly compared to, for example, a case in which high-temperature air blown up from the heating device toward the ceiling wall of the sauna room is successively pushed down by the high-temperature air blown up later, heating the area near the bottom.This makes it possible to achieve an appropriate atmospheric temperature state with a small temperature gradient early on, and improves the comfort of the sauna.

[0020] In this case, the heated air in the internal space directly comes into contact with the waiting area, so that the ambient temperature in the vicinity of the waiting area rises more quickly, shortening the waiting time for sauna bathing and reducing the costs of operating the sauna equipment, such as utility bills.

[0021] Furthermore, it is possible to raise the temperature near the bottom of the sauna room more quickly and maintain it at a temperature above the activity temperature of mold, thereby providing a hygienic sauna apparatus with less mold growth.

[0022] (b) In addition to the effect described in (a) above, the sauna apparatus according to the second aspect of the present invention has the following unique effect: In this invention, a first intake fan is provided in the internal space to introduce the airflow in the flow path from the in-wall air passage to the in-floor air passage into the internal space, which promotes the introduction of high-temperature air into the internal space and the blowing out of the internal space into the sauna room, thereby promoting an increase in the ambient temperature at the bottom of the sauna room and improving the comfort of using the sauna apparatus.

[0023] (c) In the third invention of the present application, in the sauna apparatus of the first or second invention, a second intake fan is provided at a position near one side of the floor surface and close to the entrance / exit door of the sauna room, which introduces the air flow in the floor air passage into the sauna room.The air flow introduced into the sauna room by the second intake fan functions as an air curtain in the entrance / exit door area, preventing the warm air in the sauna room from flowing out through the entrance / exit door when the sauna room is opened or closed.As a result, a sudden drop in temperature near the bottom of the entrance / exit door caused by the opening and closing of the entrance / exit door is suppressed, and the temperature rises again quickly after a temperature drop.As a result, the comfort of using the sauna apparatus is maintained well.

[0024] (d) In addition to the effects described in (a) or (b) above, the sauna apparatus according to the fourth aspect of the present invention has the following unique effect: In this invention, an air flow collection and guide is provided in a location directly above the heating device near the ceiling wall of the sauna room, which collects part of the air flow moving upward from the heating device and guides it to the high-temperature air inlet side, ensuring the introduction of high-temperature air into the in-wall air passage and further into the in-floor air passage and the internal space, thereby improving the comfort of the sauna apparatus.

[0025] (e) In addition to the effects described in (a) or (b) above, the sauna apparatus according to the fifth aspect of the present invention has the following unique effect: That is, in this invention, in the sauna apparatus according to the first, second or third aspect of the present invention, the in-floor air passage is configured such that the upper surface side of the passage is made of a plywood having a large number of vents and a stainless steel pan stacked on the upper surface of the plywood, and part of the air flowing through the in-floor air passage comes into contact with the stainless steel pan through the vents of the plywood, so that the stainless steel pan comes into contact with the heated air coming into contact with it through the vents and is heated, generating radiant heat toward the sauna room, which promotes an early rise in the temperature of the upper surface side of the stainless steel pan, i.e., the atmospheric temperature near the bottom of the sauna room, thereby improving the comfort of using the sauna apparatus. [Brief description of the drawings]

[0026] [Figure 1] 1 is an overall system diagram of a sauna apparatus according to an embodiment of the present invention. [Diagram 2] 2 is a longitudinal sectional view of a main part taken along line AA in FIG. 1. [Diagram 3] FIG. 2 is a longitudinal sectional view of a main part of BB in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Hereinafter, the sauna apparatus of the present invention will be described in detail based on a preferred embodiment.

[0028] FIG. 1 shows the entire system of a sauna apparatus Z according to an embodiment of the present invention. 2 and 3 show the configuration of the main part.

[0029] This sauna apparatus Z is primarily used as a home sauna apparatus and includes a sauna room 1 of a required size, with a heating device 8 placed in a corner away from the entrance door 10 of the sauna room 1. A standby unit 7 is placed opposite the heating device 8.

[0030] "Heating device 8" The heating device 8 is constructed by arranging an electric heater 15 as a heat source and heat storage stones 16 for generating the loyly effect inside a mesh cylinder of a given size. The surrounding air is heated by the electric heater 15, becoming high-temperature air, which gradually rises due to buoyancy toward the ceiling wall 6, gradually raising the indoor temperature from the ceiling wall 6 side of the sauna room 1, while moving downwards as it is pushed down by the heated air rising later, gradually raising the atmospheric temperature of the sauna room 1.

[0031] Meanwhile, the heat storage stones 16 are heated and stored by the heated air moving upward from the electric heater 15 or around the electric heater 15. When the humidity inside the sauna room 1 drops, water is poured onto the heat storage stones 16 as necessary to generate steam and restore the humidity inside the room. At this time, negative ions are generated in the atmosphere, creating a loyly effect.

[0032] "In-wall ventilation channel 34" Inside the first side wall 3 of the sauna room 1, to which the heating device 8 of the sauna room 1 is arranged close, there is provided an in-wall air passage 34 extending vertically, as shown in Fig. 2. This in-wall air passage 34 extracts a portion of the high-temperature air that is generated in the heating device 8 and rises due to buoyancy toward the ceiling wall 6 and passes it to an in-floor air passage 28 on the floor surface 2 side, which will be described later, and its upper end faces the inside of the sauna room 1 via a high-temperature air inlet 35 provided in the inner panel 32. Meanwhile, the lower end of the in-wall air passage 34 communicates with the in-floor air passage 28, which will be described later.

[0033] "Air flow collection guide portion 38" An air flow collecting and guiding section 38 is provided near the ceiling wall 6 directly above the heating device 8 to collect a portion of the high-temperature air rising due to buoyancy from the heating device 8 and collect it on the side of the high-temperature air inlet 35. This air flow collecting and guiding section 38 is composed of a partition wall 37 of a certain height surrounding the periphery of the high-temperature air inlet 35, and a rectangular guide plate 36 disposed within the partition wall 37 so as to incline downwardly from the edge on the side of the inner panel 32 toward the outside.

[0034] By providing this air flow collection guide section 38, a portion of the high-temperature air moving upward from the heating device 8 flows into the air flow collection guide section 38, and then moves upward along the slope of the guide plate 36 and flows into the in-wall air passage 34 from the high-temperature air inlet 35. In this case, since the partition wall 37 is provided, the required amount of air can be reliably collected and introduced into the in-wall air passage 34, ensuring the introduction of high-temperature air into the in-wall air passage and further into the in-floor air passage and the internal space, thereby improving the comfort of the sauna apparatus.

[0034] "In-floor ventilation channel 28" The heating device 8 and standby section 7 are placed on the floor surface 2 of the sauna room 1, and the configuration is characteristic of the present invention. That is, the floor surface 2 has a plurality of underfloor supports 21 arranged at a predetermined interval, and notched grooves 22 are formed at a predetermined interval on the upper surface side of the underfloor supports 21. The notched grooves 22 function as ventilation passages.

[0035] A plywood board 23 with a number of ventilation holes 24 is placed on the upper surface of each underfloor support 21. Furthermore, a stainless steel pan 25 made of a stainless steel plate is placed on the upper surface of this plywood board 23. Furthermore, a wooden lattice 26 is placed on the upper surface of this stainless steel pan 25.

[0036] Additionally, the lower half of each of the under-floor supports 21 is filled with a heat insulating material 27. An in-floor air passage 28 extending across the entire area of ​​the floor surface 2 is formed between the upper surface of this heat insulating material 27 and the lower surface of the plywood 23. In this case, each of the notched grooves 22 of the sauna room 1 serves as a communication passage, and the in-floor air passage 28 extends across the entire area of ​​the floor surface 2.

[0037] "Waiting Department 7" The waiting section 7 is for the sauna user to sit on and take a sauna bath, and in this embodiment, it is configured with a seat section 71, an upper front wall section 72 on its front side, a footrest section 73, a lower front wall section on its front side, and a backrest section 75 located behind the seat section 71. Each of these sections is made up of multiple plate materials, and a horizontally long ventilation gap is formed between each plate material.

[0038] "Interior Space 14" An internal space 14 is formed between the inside of the waiting section 7 and the stainless steel pan 25 of the floor surface 2. In this internal space 14, as shown in Figures 1 and 3, three intake fans 41 are attached, penetrating the upper surface of the floor surface 2 facing this internal space 14, i.e., the abutment part of the plywood 23 and the stainless steel pan 25, and the high-temperature air on the ceiling side of the sauna room 1 is forcibly sucked in through the in-wall air passage 34 and in-floor air passage 28 by the suction force of each intake fan 41.

[0039] In this case, since the intake fans 41 are arranged in a row at predetermined intervals in the longitudinal direction of the waiting section 7, the high-temperature air in the in-floor air passage 28 is sucked in as evenly as possible from the entire area of ​​the in-floor air passage 28. This means that the high-temperature air comes into contact with and is heated as evenly as possible over the entire area in the planar direction of the stainless steel pan 25, generating radiant heat over a wide area, and therefore the atmospheric temperature near the floor surface 2 of the sauna room 1 is raised as evenly as possible, improving the temperature gradient in the vertical direction of the sauna room 1 and increasing comfort within the sauna room 1.

[0040] In addition, the high-temperature air introduced into the internal space 14 is blown directly into the sauna room 1 through the gaps in each part of the waiting section 7, thereby raising the temperature at the bottom side of the sauna room 1 and, in cooperation with the radiant heat from the stainless steel pan 25 side, contributing to further improving the temperature gradient in the vertical direction of the sauna room 1.

[0041] By improving the temperature gradient in the vertical direction of the sauna room 1 in this way, the ambient temperature in the sauna room 1 approaches an appropriate temperature more quickly, allowing the user to experience the comfort of a sauna bath.

[0042] Meanwhile, a second intake fan 42 that introduces the air flow in the in-floor air passage into the sauna room is provided at a position toward one side of the floor surface 2 and close to the entrance door 10 of the sauna room 1. The suction force of this second air supply fan 42 prevents the flow of high-temperature air in the in-floor air passage 28 from being excessively biased toward the center of the sauna room 1 by the suction force of the first intake fans 41, and the high-temperature air flows up to the vicinity of the entrance door 10.

[0043] And, because the second air supply fan 42 blows out the high-temperature air in the in-floor air passage 28 directly toward the bottom of the sauna room 1, this blown-out air flow functions as an air curtain at the entrance door 10. As a result, the warm air flow inside the sauna room is prevented from flowing out of the entrance door 10 when the entrance door 10 is opened or closed, a sudden drop in temperature near the bottom of the entrance door 10 caused by the opening and closing of the entrance door 10 is prevented, and the temperature quickly rises again after a drop in temperature, so that the comfort of using the sauna apparatus Z is well maintained.

[0044] "Ventilation structure" In the sauna device Z, a fresh air inlet 11 is provided near the bottom edge of the entrance door 10, while an exhaust outlet 12 is provided in a corner of the ceiling diagonally opposite the fresh air inlet 11, and the opening of the exhaust outlet 12 is adjusted as necessary to ventilate the sauna room 1. Also, reference numeral 13 in Fig. 1 denotes an inspection window.

[0045] "others" (1) In this embodiment, the sauna apparatus Z is described as being "primarily used as a home sauna apparatus." However, the sauna apparatus of the present invention is not limited to home use and can be widely applied, for example, for large facilities and public use. (2) In this embodiment, the above-mentioned intra-wall air passage 34 is provided in one wall portion, but the present invention is not limited to this. For example, it may be provided in each of two wall portions that are adjacent to each other through an inside corner. [Industrial Applicability]

[0046] The sauna apparatus according to the present invention can be widely used in sauna rooms in which a heating device serving as a heat source and a waiting section in which sauna users wait are arranged. [Explanation of symbols]
