Technical Field

[0001] The utility model relates to the technical field of steam furnaces, in particular to a heating furnace for a sauna cabin. Background Art

[0002] Saunas can be divided into dry saunas and wet saunas according to the different steam states. Among them, dry saunas generate hot air by heating stones or special heating elements, resulting in a sauna form with a relatively high temperature (about 80°C) and a relatively low humidity (generally below 20%). Wet saunas generate steam by adding water to heated stones or steam generators, resulting in a sauna form with a relatively low temperature (about 60°C) and a relatively high humidity (up to over 40%). According to different heat sources, they can be roughly divided into electric heating furnaces and firewood heating furnaces. Among them, for families in regions such as Europe where winters are cold and there are independent courtyards, compared with the disadvantage of fast heat dissipation of electric heating furnaces, they are more enthusiastic about using firewood heating furnaces to generate steam for sauna cabins.

The cobblestones are located inside the sauna cabin, and the stove is connected to the outside of the sauna cabin to prevent toxic gases such as carbon dioxide generated in the stove from entering the sauna cabin. In this way, steam is generated by splashing water on the cobblestones inside the sauna cabin. However, the existing such firewood heating furnaces are only used to heat cobblestones, with a too single function, resulting in a large waste of the heat of the fuel. Therefore, in order to solve the above deficiencies, the heating furnace for a sauna cabin of this application is proposed. Summary of the Utility Model

[0027] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant accompanying drawings. The preferred embodiments of the present utility model are shown in the accompanying drawings.

[0028] Such as Figures 1 to 3As shown in the figure, a heating furnace 10 for a sauna cabin includes a furnace base 100 and a heating assembly 200. The heating assembly 200 includes a partition seat 210, a smoke exhaust pipe 220, a water tank 230, and a combustion net 240. The partition seat 210 is disposed within the furnace base 100 such that the lower side surface of the partition seat 210 and the inner side wall of the furnace base 100 jointly enclose a combustion chamber 110, and the upper side surface of the partition seat 210 and the inner side wall of the furnace base 100 jointly enclose a material placement groove 120. The smoke exhaust pipe 220 is disposed vertically on the partition seat 210 and is in communication with the combustion chamber 110. The water tank 230 is disposed on the smoke exhaust pipe 220 such that the smoke exhaust pipe 220 passes through the water tank 230. The combustion net 240 is in communication with the water tank 230 and is located on one side surface of the partition seat 210 close to the combustion chamber 110.

[0029] It should be noted that the partition seat 210 is welded to the inner side wall of the furnace base 100, so that the partition seat 210 divides the inner side wall of the furnace base 100 into two independent upper and lower regions. The region located at the lower side is the combustion chamber 110 jointly enclosed by the lower side surface of the partition seat 210 and the inner side wall of the furnace base 100. The region located at the upper side is the material placement groove 120 jointly enclosed by the upper side surface of the partition seat 210 and the inner side wall of the furnace base 100. The material placement groove 120 is used to accommodate cobblestones. The smoke exhaust pipe 220 is located at the middle position of the partition seat 210, and the smoke exhaust pipe 220 is in communication with the combustion chamber 110. Further, the water tank 230 is welded to the smoke exhaust pipe 220, so that the smoke exhaust pipe 220 penetrates through the water tank 230, and there is a gap between the water tank 230 and the furnace base 100. The combustion net 240 is located within the combustion chamber 110 and is in communication with the water tank 230. Thus, when fuels such as firewood / coal are placed in the combustion chamber 110 for combustion, the partition seat 210 and the combustion net 240 will be heated by combustion, so that the cobblestones in the material placement groove 120 are heated. Further, during the process of the exhaust gas being discharged through the smoke exhaust pipe 220, the smoke exhaust pipe 220 will heat the water in the water tank 230. Since the combustion net 240 is located within the combustion chamber 110, as the combustion net 240 is heated, the water inside will form a circulating flow with the water in the water tank 230, thereby accelerating the heating of the water in the water tank 230. Thus, compared with the existing heating furnace with a single function that can only heat cobblestones alone, the heating furnace 10 for a sauna cabin of the present application can heat the cobblestones and the water tank 230 simultaneously, effectively reducing the waste of heat of the fuel and being more economical.

[0030] In one embodiment, the partition seat 210 is fixedly welded to the inner side wall of the furnace base 100. Thus, it can ensure a reliable isolation between the formed combustion chamber 110 and the material placement groove 120.

[0031] As Figure 2As shown, in one embodiment, the heating assembly 200 further includes two circulation pipes 250. The two circulation pipes 250 are respectively communicated with the combustion net 240, and the two circulation pipes 250 respectively pass through the exhaust pipe 220 to be communicated with the water tank 230.

[0032] It should be noted that the two circulation pipes 250 are located on the inner side wall of the exhaust pipe 220, and both ends of the two circulation pipes 250 are respectively communicated with the water tank 230 and the combustion net 240. Thus, water can circulate and flow for heating among the circulation pipe 250, the combustion net 240, and the water tank 230, accelerating the heating efficiency of the water in the water tank 230.

[0033] In one embodiment, one end of the two circulation pipes 250 located in the water tank 230 has a height difference. Thus, as the combustion net 240 is heated, there is a temperature difference in the water of the water tank 230. Therefore, setting one end of the two circulation pipes 250 located in the water tank 230 with a height difference is beneficial to the water in the water tank 230 to circulate into the combustion net 240 for heating.

[0034] As Figure 1 and Figure 2 shown, in one embodiment, the exhaust pipe 220 includes a support pipe body 221, a terminal pipe body 222, and a plurality of heat dissipation pipe bodies 223. One end of the support pipe body 221 is arranged on the partition seat 210, and the other end of the support pipe body 221 extends into the water tank 230. One end of each heat dissipation pipe body 223 is communicated with the support pipe body 221, and the other end of each heat dissipation pipe body 223 is communicated with the terminal pipe body 222. And each heat dissipation pipe body 223 is located in the water tank 230. The end of the terminal pipe body 222 away from the heat dissipation pipe body 223 extends out from the top of the water tank 230.

[0035] It should be noted that the support pipe body 221 and the partition seat 210 are fixed by welding. One end of each heat dissipation pipe body 223 is welded and fixed to the end of the support pipe body 221 away from the partition seat 210, and the other end of each heat dissipation pipe body 223 is welded and fixed to the terminal pipe body 222. Among them, each heat dissipation pipe body 223 is located in the water tank 230, and the support pipe body 221 extends into the water tank 230 from the lower end surface of the water tank 230. The terminal pipe body 222 extends out from the upper end surface of the water tank 230. Thus, after the combustion waste gas enters the support pipe body 221 from the combustion chamber 110, it then enters each heat dissipation pipe body 223 and is discharged from the terminal pipe body 222. Since each heat dissipation pipe body 223 increases the contact area with the water in the water tank 230, it can increase the utilization of the waste heat of the waste gas by the water tank 230. Thus, the heat utilization of the fuel is effectively improved.

[0036] In one embodiment, the support pipe body 221 and the heat dissipation pipe body 223, the heat dissipation pipe body 223 and the terminal pipe body 222, the support pipe body 221 and the water tank 230, and the terminal pipe body 222 and the water tank 230 are all fixed by welding.

[0037] In one embodiment, four heat dissipation tube bodies 223 are provided, and intervals are provided between the four heat dissipation tube bodies 223. In this way, it is possible to contact the water in the water tank 230 as much as possible.

[0038] As Figure 1 shown, in one embodiment, a protective cover 300 is provided on the outer side wall of the furnace base 100, and an interval is provided between the protective cover 300 and the furnace base 100. In this way, it is possible to prevent users from accidentally touching the outer side wall of the furnace base 100 and being scalded.

[0039] As Figure 1 shown, in one embodiment, a plurality of heat dissipation holes 310 are formed in the protective cover 300. In this way, the heat dissipation efficiency of the protective cover 300 can be improved.

[0040] As Figure 4 shown, in one embodiment, a slag collection hole 130 is provided on the inner bottom wall of the furnace base 100, and a number of filter rods 140 are arranged at intervals in the slag collection hole 130.

[0041] It should be noted that after the fuel burns sufficiently in the combustion chamber 110, the waste slag is discharged from the slag collection hole 130. On the one hand, the filter rods 140 ensure good ventilation in the combustion chamber 110, and on the other hand, they prevent unburned fuel from being discharged from the combustion chamber 110.

[0042] In one embodiment, the inner bottom wall of the furnace base 100 is a downward-sloping structure in the direction close to the slag collection hole 130. In this way, it is convenient to discharge the waste slag in the combustion chamber 110 from the slag collection hole 130.

[0043] As Figure 1 shown, in one embodiment, a closable furnace door 400 is provided on the furnace base 100. In this way, the heat loss of the fuel in the combustion chamber 110 can be reduced.

[0044] The above-described embodiments merely represent several embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
