Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 to 2, the present utility model provides a technical solution: a far-infrared sauna room 1 with a lower auxiliary heating device. An infrared heating device 6, a control panel 12 are provided on the inner wall of the sauna room 1, and a control system 11 is provided on the top of the sauna room 1. A seat bench 2 is provided inside the sauna room 1. The seat bench 2 includes a seat board and a bench seat 2 located below the seat board. The bench seat 2 is a hollow cylinder, including a front side plate 21 and a left side plate 2. An air outlet hole 211 is provided on the front side plate 21 of the bench seat 2, and an air inlet hole 21 is provided on the left side plate 2. A lower auxiliary heating device is provided inside the bench seat 2. The lower auxiliary heating device includes a blower 4 and a PTC honeycomb heating element 5. The PTC honeycomb heating element 5 is installed at the position of the air outlet hole 211, and the blower 4 is installed inside the bench seat 2. In the prior art, the infrared heating device 6 is located in the upper middle part of the inner wall of the sauna room 1. The heating process of the sauna room 1 is mainly as follows: first, the space in the upper middle part of the sauna room 1 is heated, and then the temperature of the entire sauna room 1 is made uniform by the air circulation heating method. Since the air circulation heating method is relatively slow, therefore, in this solution, by setting a heating device in the bench seat 2, that is, the PTC honeycomb heating element 5 with heat function and the blower 4, the lower space of the sauna room 1 can be quickly heated up, thereby shortening the time required for the entire sauna room 1 to reach a uniform temperature and bringing comfort to the user.

[0019] The lower auxiliary heating device further includes a wind guide cylinder 3. The wind guide cylinder 3 is provided inside the bench seat 2. The PTC honeycomb heating element 5 is arranged at the wind guide outlet 31 position of the wind guide cylinder 3, and the blower 4 is arranged at the wind guide inlet 331 position of the wind guide cylinder 3. The wind guide outlet 31 of the wind guide cylinder 3 is located behind the air outlet hole 211 of the front side plate 21. Setting the wind guide cylinder 3 is beneficial to increasing the air flow rate passing through the PTC honeycomb heating element 5, thereby being beneficial to quickly heating up the lower space of the sauna room 1.

[0020] The wind guide cylinder 3 includes a bottom plate 33 and an arc-shaped top plate 32 connected to the bottom plate 33. Its shape is a quarter sphere. A wind guide inlet 331 is opened at the bottom plate 33 position away from the wind guide outlet 31 of the wind guide cylinder 3. A blower installation shell 34 is also attached directly below the wind guide inlet 331. The blower installation shell 34 is connected to the wind guide cylinder 3 through the wind guide inlet 331. A through hole 341 is also provided at the bottom of the blower installation shell 34. A blower is installed in the blower installation shell 34.

[0021] The blower selects a cross-flow blower assembly. The through hole 341 is provided on the side of the blower installation shell 34 away from the wind guide inlet 331, so as to increase the air flow rate passing through the wind guide inlet 331, as shown in the appendix Figure 2 shown.

[0022] The front side of the air duct 3 (i.e., the air outlet side of the air duct) is installed on the inner wall of the bench seat 2 where the air outlet hole 211 is located. The air outlet 31 is matched with the air outlet hole 211, and their sizes are matched to further increase the air flow velocity passing through the PTC honeycomb heating element 5, so as to more effectively heat up the lower space of the sauna room 1 quickly.

[0023] Air guide strips (not shown) with a set installation spacing are installed at the air outlet hole 211 to play a role in guiding air and protection.

[0024] A first temperature sensor 71 is provided at the upper part of the inner wall of the sauna room 1, and a second temperature sensor 72 is provided at the lower part. The first temperature sensor 71, the second temperature sensor 72, the fan 4, the infrared heating device 6, and the PTC honeycomb heating element 5 are electrically connected to the control system 11. The first temperature sensor is used to monitor the temperature at the upper part of the space of the sauna room 1 in real time, and the second temperature sensor is used to monitor the temperature at the lower part of the space of the sauna room 1. When the temperature at the lower part of the space of the sauna room 1 is lower than that at the upper part, the fan 4 is started in time and the PTC honeycomb heating element 5 is turned on to heat the lower space. When the temperatures of the two parts are the same, the fan 4 is turned off in time and the PTC honeycomb heating element 5 is disconnected.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
