Description

Technical Field

[0001] This utility model specifically relates to a ring-shaped air outlet bathroom heater. Background Technology

[0002] Most bathroom heaters on the market currently use a dual-volute structure, with one volute for heating and the other for ventilation. To achieve a greater airflow, a higher-power volute is usually required, or the airflow efficiency needs to be improved while maintaining the same volute power, resulting in a larger unit size. The uniformity of airflow from a bathroom heater directly affects the user experience; further improvements are needed to make the airflow more even.

[0003] Therefore, it is necessary to provide a ring-shaped air outlet bathroom heater that uses a bidirectional blowing volute for air delivery. Combined with the ring-shaped air outlet mechanism, the space occupied by the bathroom heater is greatly reduced, the air delivery efficiency is higher, and the bathroom heater has a higher cost performance and a wider range of applications. Utility Model Content

[0004] The purpose of this invention is to provide a ring-shaped air outlet bathroom heater, which solves the shortcomings of existing bathroom heaters that occupy a large space and have uneven air outlet.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A ring-shaped exhaust fan for bathroom heaters, characterized in that it includes a housing with an air exchange port and an exhaust port; a blower volute is provided inside the housing, and the rotor of the blower volute has two layers of blades, wherein one layer of blades is arranged counterclockwise and the other layer of blades is arranged clockwise, so that the blower volute has two air outlets, one air outlet is connected to the air exchange port through an air exchange channel, and the other air outlet is connected to the exhaust port through an exhaust channel; the exhaust port is connected to a ring-shaped exhaust mechanism, and the ring-shaped exhaust mechanism has a ring-shaped airflow channel.

[0007] In this invention, the annular air outlet mechanism includes an outer shell and an inner shell. The outer shell is trumpet-shaped, and the inner shell is conical. The outer shell is fitted over the inner shell, forming an annular airflow channel between them. This design results in a conical inner shell with low wind resistance and better air delivery, while the trumpet-shaped outer shell creates a more uniform annular airflow.

[0008] Furthermore, the inner shell is provided with flow-dividing grids, which are arranged along the direction of the conical generatrix. By setting the flow-dividing grids, the airflow direction is defined, making the airflow more uniform after passing through the annular airflow channel.

[0009] In this invention, the inlet of the annular air outlet mechanism is rectangular, and the outlet of the annular air outlet mechanism is circular. This design matches the airflow in the inlet with the airflow in the outlet channel, and through the guidance of the annular air outlet mechanism, ultimately forms an annular air outlet, further improving the uniformity of the airflow.

[0010] Furthermore, the diversion grille is positioned diagonally along the rectangular inlet of the annular air outlet mechanism. This arrangement allows the diversion grille to better match the inlet, resulting in higher air delivery efficiency.

[0011] In this invention, the air outlet duct and the ventilation duct share a common channel section, which is formed by a first common section and a second common section arranged opposite each other. This arrangement reduces the space occupied by the entire air supply duct, resulting in a smaller bathroom heater / ventilation unit that can meet the needs of more application scenarios.

[0012] Furthermore, the first common segment is an arc-shaped plate, and the second common segment is an arc-shaped plate.

[0013] In some embodiments of this utility model, the air outlet channel further includes a first guide channel section, which is connected to the common channel section and to the exhaust port; the first guide channel section is formed by the first channel section and the second channel section facing each other.

[0014] Furthermore, the first channel segment is an arc-shaped plate, and the second channel segment is a straight plate.

[0015] In this invention, the first flow channel section is equipped with a heater.

[0016] In this invention, a guide element is provided at the exhaust port, which is a guide channel with an isosceles trapezoidal cross-section. By setting the guide element, the airflow direction of the exhaust channel is changed. Moreover, the cross-section of the guide element is an isosceles trapezoid, which can guide the airflow in three directions, forming a certain diffusion airflow, guiding it to the annular exhaust mechanism, reducing losses, obtaining greater exhaust efficiency, and at the same time making the airflow entering the annular exhaust mechanism as uniform as possible in all directions.

[0017] In some embodiments of this utility model, the ventilation channel further includes a second flow guiding channel section, which is connected to the common channel section and to the ventilation port; the second flow guiding channel section is formed by a third channel section and a fourth channel section facing each other.

[0018] Furthermore, the third channel segment is a straight plate, and the fourth channel segment is a straight plate.

[0019] Furthermore, the ventilation port is located between the third channel section and the fourth channel section.

[0020] This utility model has the following beneficial effects:

[0021] (1) The present invention adopts a bidirectional blowing volute and a ring air outlet mechanism to achieve ring air outlet, which makes the air outlet more uniform. At the same time, it improves the air supply efficiency of the air supply channel of the bathroom heater, reduces the space occupied by the bathroom heater, and has a wider range of applications.

[0022] (2) This utility model of bathroom heater reduces the space occupied by the air duct by optimizing the air outlet channel and the ventilation channel, and improves the air supply efficiency. At the same time, it adds a guide component and improves the structure of the ring air outlet mechanism, so that the air outlet of the ring air outlet mechanism is more uniform.

[0038] like Figure 1-13 The ring-shaped air outlet bathroom heater shown includes a housing 1, a blower housing 2, a heater 3, and a ring-shaped air outlet mechanism 6.

[0039] The top of the casing 1 has a circular air inlet 102 and a rectangular exhaust outlet 103. The exhaust outlet 103 is equipped with a guide element 10, which is an isosceles trapezoidal cross-section guide channel. The exhaust outlet 103 is also connected to an annular air outlet mechanism 6, which has an annular airflow channel. A ventilation port 101 is located on the side wall of the casing 1. This arrangement, with both the air inlet 102 and the exhaust outlet 103 located at the top of the casing 1, allows for internal airflow circulation within the bathroom, improving ventilation efficiency and facilitating rapid heating. Simultaneously, the location of the air inlet 102 at the top of the casing 1 and the ventilation port 101 on the side wall of the casing 1 enables airflow circulation between the bathroom and the outside, forming an internal-external circulation for better ventilation.

[0040] In this embodiment, the annular air outlet mechanism 6 includes an outer shell 601 and an inner shell 602. The outer shell 601 is trumpet-shaped, and the inner shell 602 is conical. The outer shell 601 is fitted over the inner shell 602, forming an annular airflow channel between them. The inlet 604 of the annular air outlet mechanism 6 is rectangular, and the outlet 605 is circular. A diversion grille 603 is distributed on the inner shell 602. The diversion grille 603 is arranged along the generatrix of the conical shape and along the diagonal of the rectangular inlet 604 of the annular air outlet mechanism 6. This arrangement allows the diversion grille 603 to better match the inlet 604, resulting in high air delivery efficiency and uniform air distribution for the entire annular air outlet mechanism 6.

[0041] The housing 1 contains a blower volute 2, with its air inlet 202 facing the air inlet 102 at the top of the housing 1.

One outlet 201 connects to the ventilation outlet 101 via a ventilation channel 4, and the other outlet 201 connects to the exhaust outlet 103 via an exhaust channel 5. This arrangement allows the rotor 203 of the blower volute 2 to generate different airflows at the outlets 201, which are directed through the ventilation channel 4 to the ventilation outlet 101 and through the exhaust channel 5 to the exhaust outlet 103. Thus, the blower volute 2 can perform two functions: ventilation and heating. This design maximizes the use of space and reduces the space occupied by the heater / ventilation unit, while also providing higher air delivery efficiency. In this embodiment, the air outlet duct 5 and the ventilation duct 4 share a common duct section 7, which is formed by a first common section 11 and a second common section 12 facing each other. The first common section 11 is an arc-shaped plate, and the second common section 12 is an arc-shaped plate. The air outlet duct 5 also includes a first guide duct section 8, which is connected to the common duct section 7 and to the exhaust port 103. The first guide duct section 8 is formed by a first duct section 13 and a second duct section 14 facing each other. The first duct section 13 is an arc-shaped plate, and the second duct section 14 is a straight plate. The first guide duct section 8 is equipped with a heater 3, which is located between the first duct section 13 and the second duct section 14. The ventilation channel 4 also includes a second guide channel section 9, which is connected to the common channel section 7 and to the ventilation port 101. The second guide channel section 9 is formed by a third channel section 15 and a fourth channel section 16 facing each other. The third channel section 15 and the fourth channel section 16 are both straight plates. The ventilation port 101 is located between the third channel section 15 and the fourth channel section 16.

[0042] This utility model of bathroom heater adopts a double-layer blower shell 2, combined with a ring-shaped air outlet mechanism 6, which reduces costs while having higher blowing efficiency, achieves ring-shaped air outlet, occupies little space, has lower requirements for bathroom ceiling space, and has a wider range of applications.
