[0033] Please combine Figures 1 to 4 As shown, the present application first provides a box structure, including a box 10, an air duct 20, a wind shield 30 and a panel 40. The air duct 20 is arranged inside the box 10, and the wind shield 30 can be adjustably arranged at the end of the air flow path direction inside the air duct 20, so that the wind shield 30 has a plurality of installation positions facing different directions. At each installation position, the wind shield 30 can guide the air flow path inside the air duct 20 to the corresponding direction; the panel 40 is fixed to the box 10, so that the air flow path guided by the wind shield 30 is toward the air outlet 41 of the panel 40.

[0034] For ease of description, the orientation in this article refers to direction and / or position, that is, the orientation of different installation positions may be only different in position, only different in direction, or different in direction and position, etc. L1 is the center line of the panel 40, and L2 is the center line of the air outlet 41.

[0035] In the present application, the wind shield 30 is used to cooperate with the air duct 20 to form an air flow path. By installing the wind shield 30 to different installation positions, the outlet of the air flow path can be oriented to different directions. When the style of the adjustment panel 40 causes the position of the air outlet 41 to change, it is only necessary to install the wind shield 30 to the corresponding installation position to change the outlet direction of the air flow path and make it oriented to the new position of the air outlet 41. There is no need to re-open the mold to produce the corresponding box 10, which effectively reduces the cost increase caused by changing the style of the panel 40.

[0036] Please combine Figures 5 to 7 As shown, in some embodiments, the box body 10 and the air duct 20 open in the same direction, and the box body structure also includes an air collecting plate 50, which has an air collecting plate outlet 51 that passes through the opening direction of the box body 10, and the air collecting plate 50 can be fixed to the box body 10 and close part of the opening of the air duct 20 to form an air flow path with the outlet toward the air collecting plate outlet 51 through the air duct 20, the air collecting plate 50 and the wind shield 30; when the style of the panel 40 is changed, the air collecting plate 50 needs to be replaced accordingly so that the air collecting plate outlet 51 corresponds to the air outlet 41.

[0037] For the convenience of the following description, a plane direction perpendicular to the outlet direction of the box body 10 is defined as a first plane direction.

[0038] The airflow first flows along the first plane direction in the airflow path formed by the air duct 20 until it flows to the position of the wind shield 30. The wind shield 30 is at least partially perpendicular to or inclined to the first plane. The airflow is blocked by the wind shield 30 and flows along the wind shield 30 toward the opening of the box body 10. The air is discharged through the air collecting plate outlet 51 and the air outlet 41 under the guidance of the wind shield 30.

[0039] Of course, in some other embodiments, the air duct 20 may also be other structures. For example, the air duct 20 is tubular, forms an air flow path inside itself and is open at the end, and changes the outlet direction of the air flow path by a wind shield 30, etc. This application does not make further limitations here.

[0040] Please combine Figures 6 to 8 As shown, in some embodiments, the wind shield 30 includes an air guide surface 31, and the air guide surface 31 includes a plurality of air guide segments 31a connected in sequence along the opening direction of the box body 10, and two adjacent air guide segments 31a are tangent to each other; the projection of at least one air guide segment 31a along the x-axis direction is an arc, and the center of the air guide segment 31a is located on the side of the air guide surface 31 close to the air flow path.

[0041] For the following description, please refer to Figure 3 As shown, the length direction of the wind shield 30 is defined as the x-axis direction.

[0042] With such arrangement, when the airflow flows to the wind shield 30, the airflow can be smoothly turned under the guidance of the arc-shaped air guide section 31a, thereby minimizing the air volume loss caused by the collision between the airflow and the wind shield 30, increasing the air volume of the bathroom heater, and also reducing the noise generated by the collision, thereby increasing the quietness of the operation of the bathroom heater.

[0043] Please combine Figures 6 to 8 As shown, in some embodiments, the projections of at least two air guide segments 31a along the x-axis direction are arc-shaped, wherein the air guide segment 31a on the side away from the air collecting plate 50 along the opening direction of the box body 10 has its center located on the side of the air guide surface 31 close to the air flow path, and the center of the other air guide segment 31a is located on the side of the air guide surface 31 away from the air flow path, and / or the end of the air guide segment 31a close to the air collecting plate 50 faces the opening direction of the box body 10. The air guide segment 31a on the side away from the air collecting plate 50 along the opening direction of the box body 10 is used to guide the air flow to turn smoothly, and the other air guide segment 31a is used to guide the air flow to flow out along the air outlet 41.

[0044] In some embodiments, the wind guide surface 31 further includes at least one wind guide segment 31 a projected as a straight line along the x-axis direction, and the wind guide segments 31 a projected as a straight line and the wind guide segments 31 a projected as an arc are alternately arranged.

[0045] In the above embodiment, the air guide segment 31a at one end away from the panel 40 is projected as a straight line, and the intersection between the air guide segment 31a and the adjacent arc-shaped air guide segment 31a corresponds to half the height of the air duct 20, that is, the center position of the airflow flowing to the wind shield 30 through the airflow path corresponds to the arc-shaped starting point of the arc-shaped air guide segment 31a, thereby ensuring that as much airflow as possible can be guided and diverted by the arc-shaped air guide segment 31a, thereby minimizing the air volume loss.

[0046] In some embodiments, the air guide surface 31 includes five air guide segments 31a. Along the center line of the air outlet 41 toward the side close to the panel 40, the projections of the five air guide segments 31a are linear, arc, linear, arc, and linear in sequence.

[0047] Please combine Figure 6 as well as Figure 7 As shown, in some embodiments, the end of the air guiding surface 31 close to the side of the air collecting plate 50 is flush with the edge of the air collecting plate outlet 51, and / or the projection of the air collecting plate outlet 51 along the straight line direction of the opening of the box body 10 falls into the air flow path.

[0048] Such a configuration can make full use of the opening space of the air outlet 51 of the air collecting plate. While ensuring that the airflow flows through the air outlet 51 of the air collecting plate without obstruction, the opening size of the air outlet 51 of the air collecting plate can be reduced as much as possible. On the one hand, it can reduce the possibility of foreign matter entering the interior of the box body 10 through the air outlet 51 of the air collecting plate in the non-working state, and on the other hand, it can also increase the overall aesthetics.

[0049] Please combine Figures 6 to 8 As shown, in some embodiments, at least one of the air collecting plate 50 , the air duct 20 and the box body 10 is provided with a slot 21 , and the wind shield plate 30 can be snapped into the slot 21 .

[0050] Of course, the wind shield 30 and any of the wind collecting plate 50, the air duct 20 and the box 10 may also adopt other commonly used fixing methods, as long as the wind shield 30 can be disassembled and assembled as needed and has multiple installation positions, the present application does not make further limitations here.

[0051] Please combine Figures 6 to 8 As shown, in some embodiments, the air duct 20 is provided with multiple groups of slots 21, each group of slots 21 corresponds to an installation position, each group of slots 21 includes two slots 21, and the two slots 21 are respectively provided on the two inner side walls of the air duct 20 along the X-axis direction, and the two slots 21 are both arranged along the opening direction of the box body 10.

[0052] A card slot 21 is provided on the air duct 20, and the card slot 21 can play a pre-positioning effect to facilitate the insertion of the wind shield 30, and each group of card slots 21 includes two card slots 21 to ensure that the wind shield 30 is fully fixed (the wind shield 30 is fixed by the air duct 20 and the wind collecting plate 50 along the center line direction of the air outlet 41) to reduce the possibility of the wind shield 30 shaking.

[0053] Please combine Figures 6 to 8 As shown, in some embodiments, the inner wall of the air duct 20 away from its own opening also has a blocking strip 22, each group of slots 21 corresponds to a blocking strip 22, and when the wind shield 30 is engaged with the slots 21, the side surface of the wind shield 30 away from the airflow path abuts against the blocking strip 22.

[0054] The blocking strip 22 can support the wind shield 30 to avoid the formation of a gap between the wind shield 30 and the air duct 20 under the impact of airflow after long-term use, thereby increasing the working stability of the bathroom heater and increasing its service life.

[0055] In some embodiments, each group of slots 21 corresponds to a group of blocking bars 22 , and a group of blocking bars 22 has two blocking bars. When the windshield 30 is engaged with the slots 21 , the windshield 30 is engaged between the two blocking bars 22 .

[0056] Please combine Figures 6 to 8 As shown, in some embodiments, the wind shield 30 is fixed to at least one of the wind collecting plate 50, the air duct 20 and the box body 10 by screws; it is only necessary to open threaded holes corresponding to each installation position on the wind collecting plate 50, the air duct 20 or the box body 10, and the outlet direction of the air flow path can be changed by fixing the wind shield 30 to the corresponding threaded holes when the style of the panel 40 is changed, and it can be directed to the position of the new air outlet 41; compared with the clamping through the card slot 21, the reliability of screw fixing is stronger.

[0057] Specifically, in some embodiments, a threaded hole is provided on one side of the wind shield 30 close to the air outlet 41 , and the wind shield 30 and the wind collecting plate 50 are fixed by screws.

[0058] In some embodiments, a side of the wind shield plate 30 close to the air outlet 41 has an abutting surface capable of abutting against the wind collecting plate 50 , and a threaded hole is provided on the abutting surface.

[0059] In some embodiments, the wind shield 30 is snap-fitted to the slot 21 , and is fixed to at least one of the wind collecting plate 50 , the air duct 20 , and the housing 10 by screws, so as to further increase the installation stability of the wind shield 30 .

[0060] In some embodiments, the box structure further includes a linear adjustment component disposed on the box 10, and the windshield 30 is disposed at the moving end of the linear adjustment component, and the linear adjustment component can drive the windshield 30 to move to each installation position. For example, the linear adjustment component includes a lead screw, and the lead screw is threadedly connected to the windshield 30, and the windshield 30 can be driven to move along the length direction of the lead screw by rotating the lead screw.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
