An air heating apparatus, or called a bathroom warmer, is an apparatus that is installed in a bathroom and blows warm air to heat a user while bathing.

As shown in fig. 1 and 2, the air heating apparatus includes a main unit 1 and an air outlet member 2, the main unit 1 having air inlets for air outlet, for example, a first air inlet 111 and a second air inlet 112 in fig. 2.

As shown in fig. 3 and 4, the air outlet part 2 has an air inlet 201 and an air outlet 202, and the air inlet 201 communicates with the air collection port of the main unit 1. When the air heating device works, air blown out from the air collecting port of the main machine 1 enters the air outlet part 2 through the air inlet 201 and is blown out from the air outlet 202 of the air outlet part 2.

As shown in fig. 5, the heater 23 is provided in the air outlet member 2, and when the air flows through the heater 23, the air is heated to warm air by the heater 23, thereby realizing the function of air-warming the air-warming device.

The heater 23 has positive and negative terminals for connection to a power source, and the positive and negative terminals may be dangerous if they are in contact with each other.

In view of the above technical problems, the present disclosure provides an air outlet member 2, and as shown in fig. 5 and 6, the air outlet member 2 includes an inner case assembly 21, an outer case assembly 22, and a heater 23. The inner housing assembly 21 is positioned inside the outer housing assembly 22, and an air duct 20 is formed between the inner housing assembly 21 and the outer housing assembly 22. The heater 23 is located in the air duct 20 and surrounds the inner housing assembly 21.

Among them, the terminal hole 22111 may be a closed terminal hole 22111, for example, the cross section of the terminal hole 22111 is rectangular, and the terminal hole 22111 has four hole walls and openings at upper and lower ends. The terminal hole 22111 may be an unsealed terminal hole 22111, for example, the cross section of the terminal hole 22111 is rectangular, but has only three hole walls and openings at the upper and lower ends, or it is understood that the terminal hole 22111 has an opening at one side in addition to the openings at the upper and lower ends, and in this case, the terminal hole 22111 may be referred to as a terminal limit groove, a terminal groove, or the like.

The embodiment of the present disclosure is not limited to the position where the terminal 231 of the heater 23 is located, and in some examples, as shown in fig. 8 and 12, the heater 23 includes a plurality of heating sections 230, and both ends of each heating section 230 have the terminal 231. The number of the support stands 2211 is plural, and each support stand 2211 is in contact with the end portions of the adjacent two heating sections 230.

In some examples, as shown in fig. 8, the heater 23 includes four heating sections 230, and the four heating sections 230 are arranged in a square ring shape. The support platforms 2211 are four, and are respectively located at four corner positions of the square ring shape.

In other examples, four heating sections 230 may also be formed of one heater 23 bent into four sides. Of course, it is also possible to form four heating sections 230 on four sides of the rectangle from three or four, or even more, heaters 23.

The components of the support table 2211 are not particularly limited in embodiments of the disclosure, and in some examples, as shown in fig. 11, the housing assembly 22 has the support table 2211. Of course, in other examples, it is also possible that the inner housing assembly 21 has a support table 2211.

In some examples, as shown in fig. 11, the wiring location of the terminal 231 extends through the bottom of the housing assembly 22 and connects to the power cord at the bottom of the housing assembly 22.

In some examples, as shown in fig. 11, the bottom of the housing assembly 22 has a stop 2213, the stop 2213 being used to limit the location of the power cord for connection with the wiring location of the terminal 231.

In some examples, as shown in fig. 11, the limit buckles 2213 are in three groups, and the positions of the three groups of limit buckles 2213 respectively correspond to the positions of three heating sections 230 of the four heating sections 230.

In some examples, as shown in fig. 12, one end of the two heating sections 230 has one terminal 231 (first terminal 231 a) and the other end has two terminals 231 (first terminal 231a and second terminal 231 b). The other two heating sections 230 have one terminal 231 (first terminal 231 a) at one end and one terminal 231 (first terminal 231 a) at the other end. As shown in fig. 13, two of the support tables 2211 have three terminal holes 22111, and the other two of the support tables 2211 have two terminal holes 22111.

In some examples, as shown in fig. 12, when all of the terminals 231 are energized, both the first heating sub-section 2301 and the second heating sub-section 2302 are operated, achieving a high gear of the heater 23. While when the first terminal 231a of the second heating sub-section 2302 is not energized, only the first heating sub-section 2301 is operated, achieving a low gear of the heater 23.

One of the first terminal 231a and the second terminal 231b is a positive terminal, and the other is a negative terminal. For example, the first terminal 231a is a positive terminal, and the second terminal 231b is a negative terminal.

In some examples, as shown in fig. 7, 8 and 14, a square ring-shaped receiving space 2120 for receiving the heater 23 is formed between the inner case assembly 21 and the outer case assembly 22, and the heater 23 is square ring-shaped and is located in the square ring-shaped receiving space 2120 of the heater 23.

in some examples, the air outlet 202 of the air duct 20 is square ring shaped, and the inner housing assembly 21 includes the inner housing 211, and the cross section of the inner housing 211 may be square to form the square ring shaped air outlet 202 with the outer housing assembly 22. Also, since the cross section of the inner case 211 is square, a square ring-shaped receiving space 2120 can be conveniently formed by the inner case 211 and the outer case assembly 22.

In some examples, the air outlet 202 of the air duct 20 has a circular shape, and then a cross section of a portion of the inner case 211 corresponding to the air outlet 202 may be configured to be circular to form the circular air outlet 202. Also, the cross section of the portion of the inner case 211 corresponding to the heater 23 may be provided in a square shape to form a square ring-shaped receiving space 2120 with the outer case assembly 22.

In other examples, when the air outlet 202 is circular, to facilitate the manufacture of the inner casing 211, the cross sections of the portions of the inner casing 211 corresponding to the air outlet 202 and the heater 23 may be circular, and the inner casing assembly 21 may further include a bracket 212, where a square annular receiving space 2120 is formed between the bracket 212 and the outer casing assembly 22.

Of course, no matter what ring shape the air outlet 202 is, the inner housing assembly 21 may include the inner housing 211 and the bracket 212, and a square ring-shaped receiving space 2120 is formed between the bracket 212 and the outer housing assembly 22.

In some examples, as shown in fig. 16, the bracket 212 includes a base plate 2121 and four support plates 2122, the base plate 2121 having a base plate opening 21211, the base plate opening 21211 surrounding the inner housing 211, the four support plates 2122 surrounding a square ring shape and supporting the heater 23.

In some examples, as shown in fig. 16 and 17, the support segment 2131 is flat plate-like and the connection segment 2132 is arcuate. Wherein the arc shape of the connecting segment 2132 may be adapted to the arc shape of the outer sidewall of the inner housing 211.

In some examples, as shown in fig. 16, the outer sidewall of the inner housing 211 has a ring groove 2113 and the floor opening 21211 of the bracket 212 surrounds the ring groove 2113. In this way, the sealability between the bracket 212 and the inner case 211 can be enhanced, and the possibility of wind being poured from the junction of the bracket 212 and the inner case 211 can be reduced, thereby reducing wind loss of wind flowing through the junction and reducing noise generated when wind flows through the junction.

In some examples, as shown in fig. 3, the outer shell assembly 22 includes a bottom shell 221 and an upper cover 222, as shown in fig. 6-8, a square annular receiving space 2120 is formed between the bottom shell 221 and the bracket 212, the bottom shell 221 has an air inlet 201, and an annular air outlet 202 is formed between the upper cover 222 and the inner shell 211.
