Because the bathroom heater is embedded into the integrated suspended ceiling or the gypsum suspended ceiling during installation, that is, the side surface and the top surface of the shell 100 are positioned above the suspended ceiling except the bottom surface of the shell 100, the air outlet 14 facing the side surface of the shell 100 can be communicated with the outside through a pipeline or other structures for ventilation.

For ease of description, the length direction of the diffuser section 13 in the present application is referred to as the Y-axis direction as shown.

In the application, by designing the structure of the air duct 10, one of the air outlets 14 is arranged at the tail end of the diffuser section 13 along the length direction of the diffuser section 13, so that the air outlet 14 faces the side surface of the shell 100 and can be used for ventilation, and therefore, in the ventilation mode, air flow can directly flow out from the corresponding air outlet 14 along the length direction of the diffuser section 13, the possibility of collision and backflow of the air flow in the air duct 10 is reduced as much as possible, the air quantity loss of ventilation air flow is reduced, and the ventilation effect is optimized.

The diffuser 13 herein refers to a wind path channel extending from the wind wheel cavity 12, and if the wind wheel cavity 12 extends to form a plurality of wind path channels or the wind path channels form a plurality of branches, one wind path channel or one branch is regarded as the diffuser 13.

Referring to fig. 1 and 4, in some embodiments, the air inlet 11 and the other air outlet 14 face the bottom surface of the housing 100.

The air inlets 11 of the ordinary bathroom heater are arranged at the joint position of the panel and the box body of the shell 100, but the arrangement mode of the air inlets 11 is only suitable for the condition that the bathroom heater is mounted on an integrated ceiling, and when the bathroom heater is mounted on a traditional gypsum roof, the air inlets 11 are blocked by the gypsum roof; in the application, the air inlet 11 is formed in the bottom surface of the shell 100, the air inlet 11 faces indoors, no matter the bathroom heater is arranged on the integrated ceiling or the gypsum top, the air inlet can be normally realized, and the double-installation requirement of the integrated ceiling and the gypsum top is met.

Referring to fig. 2 and 3, in some embodiments, the diffuser 13 is disposed along the length direction of the housing 100, and the other air outlet 14 and the wind turbine chamber 12 are located on the same side of the diffuser 13; the arrangement is used for fully utilizing the internal space of the shell 100 and improving the space utilization rate of the interior of the shell 100.

Referring to fig. 1 and fig. 4, in some embodiments, a strip-shaped opening 110 is formed on the bottom surface of the housing 100 along the length direction thereof, and the air inlet 11 and the other air outlet 14 correspond to the strip-shaped opening 110.

The air inlet 11 and the other air outlet 14 for indoor heating can exchange air flow with the indoor space through the strip-shaped opening 110, so that on one hand, the aesthetic degree of the bottom surface of the shell 100 can be improved, and the product identification degree can be increased; on the other hand, only one baffle assembly is arranged at the position of the strip-shaped opening 110 to finish the closing of the air inlet 11 and the other air outlet 14 in the non-working state, and compared with the arrangement of independent baffle assemblies for the air inlet 11 and the other air outlet 14 respectively to avoid the dust accumulation in the non-working state, the strip-shaped opening 110 provided by the application has relatively low cost by matching with a single baffle assembly, and meanwhile, the requirement of dust accumulation prevention can be met.

Referring to fig. 1 and fig. 4, in some embodiments, a trumpet-shaped wind collecting ring 15 is fixed on a side of the wind channel 10 near the bottom surface of the housing 100, the inner diameter of the wind collecting ring 15 gradually decreases toward a side near the wind wheel cavity 12 along the axis direction of the wind collecting ring 15, an opening on the side of the wind collecting ring 15 near the wind wheel cavity 12 is an air inlet 11, and the area of the air inlet 11 is smaller than or equal to the wind wheel area of the wind wheel 20.

The horn-shaped wind collecting ring 15 can increase the air inlet area, guide the air flow to enter the air inlet 11, and play a role in collecting wind, so that the air inlet quantity at the position of the air inlet 11 is increased.

Referring to fig. 1 and fig. 4, in some embodiments, a strip-shaped opening 110 is formed on the bottom surface of the housing 100 and is arranged along the length direction of the housing, the wind collecting ring 15 corresponds to the strip-shaped opening 110, and the ratio of the overlapping area of the strip-shaped opening 110 and the air inlet 11 along the axial direction of the wind collecting ring 15 to the area of the air inlet 11 is greater than or equal to 70%.

It can be understood that in an actual working state, indoor air needs to enter the air collection ring 15 after passing through the strip-shaped opening 110, if the area of the strip-shaped opening 110 corresponding to the air inlet 11 is too small, the air inlet quantity of the air collection ring 15 is affected.

Referring to fig. 4 and fig. 5, in some embodiments, an auxiliary air inlet 120 is formed on a side of the housing 100, and the auxiliary air inlet 120 is located between the bottom surface of the housing 100 and the air inlet 11.

The design of the strip-shaped opening 110 makes the actual air inlet area of the wind wheel 20 be only the overlapping part of the strip-shaped opening 110 and the air inlet 11, the air inlet area is greatly limited, and if the size of the strip-shaped opening 110 is increased, the aesthetic degree of the bottom surface of the shell 100 and the design difficulty of the corresponding baffle assembly can be affected.

Therefore, in the present application, by providing the auxiliary air inlet 120 located between the bottom surface of the housing 100 and the air inlet 11 on the side surface of the housing 100, the external air can directly enter the air collecting ring 15 through the auxiliary air inlet 120, and meanwhile, since the air collecting ring 15 is in a horn shape, the air flow entering the housing 100 through the auxiliary air inlet 120 in the radial direction can be guided, so that the air inlet volume can meet the requirement on the premise that the size of the strip-shaped opening 110 is relatively smaller.

In some embodiments, the auxiliary air inlet 120 may be a basic pattern such as a circle, triangle, quadrilateral, or a composite pattern formed by combining a plurality of basic shapes, which is not limited herein.

Referring to fig. 3 and fig. 6, in some embodiments, the bathroom warmer further includes a driving assembly 50, the damper 30 is fixedly provided with a connecting rod portion 31 extending to the outside of the air duct 10, the driving assembly 50 includes a motor 51 and a connecting rod 52 fixedly arranged on the housing 100, the connecting rod 52 is fixedly arranged on the driving end of the motor 51, the connecting rod 52 is further provided with a chute 52a, and the connecting rod portion 31 is slidably connected with the chute 52 a.

The link portion 31 may be integrally formed with the damper 30, or may be a separate member and fixed to the damper 30, and the present application is not limited thereto.

Referring to fig. 2 and 3, in some embodiments, the damper 30 is projected along the rotation center line thereof as a curved line or a multi-sectional line formed by connecting multiple sections of straight lines.

It can be understood that the air guiding surface projected as a curve or a multi-section line formed by connecting a plurality of sections of straight lines increases the guiding effect, and reduces the air quantity loss caused by collision between the air flow and the air guiding surface as much as possible.

Referring to FIG. 2, in some embodiments, the damper 30 is raised relative to the inner wall of the diffuser 13 when the damper 30 closes the other air outlet 14.

When the air door 30 closes the other air outlet 14 and the air flows along the diffuser section 13 to the air door 30, the air door 30 protrudes inward from the inner wall of the diffuser section 13 due to the direction of the air flow along the length direction of the diffuser section 13, so that the air flow can generate an outward extrusion force on the air door 30 when flowing through the air door 30, thereby ensuring that the air door 30 is tightly attached to the inner wall of the diffuser section 13 and avoiding the air leakage.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
