Description

Technical Field

[0001] This utility model relates to the field of heating devices, specifically to a heater for sauna inside a tent. Background Technology

[0002] Currently, more and more people enjoy outdoor camping activities, and in cold weather, tent heaters are needed to heat the tents. For PCT-type tent heaters, the extracted gas is heated by the PCT before being expelled. However, due to an unreasonable design of the air outlet structure, a large temperature difference occurs between the top and bottom of the tent, resulting in poor comfort for the users. Improvements are needed. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a heater for sauna inside a tent, including a shell and a fan and heating mechanism installed inside the shell. The bottom of the shell has a downward-facing air outlet. The air drawn by the fan is delivered to the air outlet after passing through the heating mechanism. An air guide net is installed at the air outlet. The air guide net has air guide plates. The air guide plates are spaced apart from each other and are inclined toward the side of the shell. An air duct is formed between two adjacent air guide plates and extends inclined toward the side of the shell.

[0005] The heater structure designed in this scheme uses a fan to draw in air, a heating mechanism to heat the airflow drawn in by the fan, and a downward-facing air outlet is placed at the bottom of the shell with an added air guide mesh. The airflow heated by the heating mechanism is blown out through the air duct between the air guides. The blown hot air is blown obliquely downward, which helps to shorten the temperature difference between the top and bottom of the tent and improve comfort.

[0006] Furthermore, the fan is located above the housing cavity, a heating mechanism is provided below the air outlet of the fan, and an air outlet is provided below the heating mechanism. This reasonable layout facilitates assembly and molding.

[0007] Furthermore, the heating mechanism includes multiple spaced PTC heating elements, with a cavity formed between adjacent PTC heating elements for gas passage. The PTC heating elements have advantages such as small size and easy installation, making them easy to assemble and helping to reduce the size of the housing.

[0008] Furthermore, the air guide cover includes a mesh cover, which is positioned above the air guide plate and horizontally disposed at the air outlet. The mesh cover helps to improve the comfort of the blown airflow.

[0009] Furthermore, it also includes a clamping mechanism, which is located on the side of the shell and facilitates connection with poles inside the tent, such as clamping the tent fabric onto the poles.

[0010] Furthermore, the clamping mechanism includes a clamp band, a fixing seat, and fasteners. The two clamp bands are hinged at one end and connected at the other end by fasteners. A fixing seat is provided on one of the clamp bands, and the fixing seat is connected to the side of the housing. The fasteners are such as bolts.

[0011] Furthermore, it also includes a control mechanism, which is connected to the fan and heating mechanism for easy control. Common control mechanisms include touch type, knob type, and button type, which can be selected according to needs.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model improves the structure of the heater, which helps to reduce the temperature difference between the top and bottom of the tent and improve the comfort of use. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3As shown, the sauna heater inside the tent in this example includes a housing 1 and a fan 2 and a heating mechanism installed inside its cavity. The fan is a common DC fan. The fan 2 is located above the cavity of the housing 1, and the inlet of the fan 2 corresponds to an air inlet 10 formed on the top wall of the housing. A grille can be installed at the air inlet for filtration. Vertically, the heating mechanism is installed below the air outlet of the fan 2. The heating mechanism can be selected according to needs. In this example, the heating mechanism is composed of PCT heating elements 3. Multiple PCT heating elements 3 are laid flat and spaced apart on the bottom wall of the housing. The distance between adjacent PCT heating elements can be selected according to needs. This serves as a cavity through which the fan draws air.

[0023] The outlet 11 is a channel formed on the wall of the housing 1 below the PCT heating element 3, with the orifice facing downwards to allow airflow. The airflow heated by the PCT heating element is discharged through the outlet. The outlet can be gradually expanding, with a smaller initial diameter below the PCT heating element and a larger diameter at the bottom of the housing. Furthermore, the end face of the outlet 11 at the bottom of the housing 1 can be convex to help reduce clogging. The fixing methods for the fan and the PCT heating element within the housing cavity are standard industry techniques and can be selected according to requirements, so they will not be elaborated further.

[0024] In this example, an air guide mesh 4 is installed at the air outlet 11. The air guide mesh 4 includes air guide vanes 41 and a mesh 42, wherein the air guide vanes 41 are located below the mesh 42, and the air guide vanes 41 are spaced apart from each other and installed at an angle towards the side of the housing 1. The air guide vanes 41 are common straight plates or curved plates, etc. Figure 2 , Figure 3 In the indicated state, the air guide 41 is tilted toward the left side of the shell 1, and an air duct 43 is formed between two adjacent air guides 41, extending obliquely toward the left side of the shell 1. The airflow heated by the PCT heating element blows out toward the left side of the shell through the air duct. The blown airflow first surges downward, and then rises due to the hot air properties, reducing the temperature difference between the top and bottom of the tent and improving comfort.

[0025] In this example, the mesh cover 42 is a common mesh surface, which is positioned above the air guide vane 41 and horizontally placed in the air outlet 11 cavity. The mesh cover helps to improve the comfort of the blown airflow by breaking up the airflow. The air guide vane 41 can be fixed to the mesh cover, or the air guide vane can be directly installed on the shell cavity wall at the air outlet, such as a fixed connection or a pivot connection to facilitate adjustment of the tilt angle, etc.

[0026] This example also includes a control mechanism 6, which is connected to the fan 2 and the PTC heating element 3. Common control mechanisms include touch panel type, knob type, and button type, which can be selected according to requirements.

[0027] To facilitate the installation of the shell inside the tent, a clamping mechanism 5 is added in this example. For example, a control mechanism 6 is installed on the left side of the shell 1, and the clamping mechanism 6 is installed on the right side of the shell 1. The clamping mechanism 6 can be directly selected from commercially available models. A common clamping mechanism 6 includes clamp straps 51, a fixing seat 53, and fasteners 52. The two clamp straps 51 are hinged at one end and connected at the other end by fasteners 52. The fasteners are such as bolts, which are screwed into threaded holes at the ends of the clamp straps. One clamp strap has a fixing seat formed on it, and the configuration of the fixing seat can be selected according to requirements. The fixing seat is used to connect to the side of the shell, such as by bolts. In addition, elastic washers can be added, such as those fixed to the opposite ends of the two clamp straps, to accommodate poles of various diameters. During use, the clamping mechanism 5 clamps the poles 7 at the tent. Figure 2 As shown.

[0028] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
