Description

Technical Field

[0001] The present invention specifically relates to a bathroom heater. Background Art

[0002] The current bathroom heaters on the market usually adopt a double volute structure with two blowing volutes in order to achieve the two functions of heating air and ventilation. One volute is used for heating air and the other volute is used for ventilation. In order to achieve a good air supply effect, two air inlets need to be opened on the casing to correspond to the air inlets of the two blowing volutes. In this way, the space reserved for the exhaust vents on the surface of the casing is limited, which limits the size of the exhaust vents and the location of the exhaust vents. This will also directly affect the layout of the internal structure of the casing, which is not conducive to the improvement of the internal air duct structure and the installation of electronic components, and is not conducive to reducing the size of the bathroom heater and further improving the performance of the bathroom heater. There is still a lot of room for improvement in how to optimize the setting of the air inlet of the blowing volute on the casing and improve the air supply efficiency of the bathroom heater.

[0003] Based on this, it is necessary to provide a bathroom heater that uses a combination of two-way blowing volute and one-way blowing volute to supply air, but only requires one blowing volute air inlet on the casing, optimizes the internal air duct structure, improves the air supply efficiency of the blowing volute, reduces the size of the bathroom heater, has a higher cost performance, and has a wider range of applications. Summary of the Invention

[0004] The purpose of the present invention is to provide a bathroom heater to solve the shortcomings of the prior art bathroom heaters that use double blowing volutes with low air supply efficiency and large space occupation.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A bathroom heater comprises a casing, which has an exhaust port and a ventilation port, and is characterized in that the casing is also provided with an air inlet, and a first blowing volute and a second blowing volute are arranged in the casing; the first blowing volute is a two-way blowing volute, having two air outlets and one air inlet, and the air inlet of the two-way blowing volute is arranged opposite to the air inlet, so that one air outlet of the first blowing volute is connected to the exhaust port through a first air outlet channel, and one air outlet of the first blowing volute is connected to the ventilation port through a second air outlet channel; the air outlet of the second blowing volute is connected to the ventilation port.

[0007] In the present invention, the air inlet and exhaust vents are located at the top of the housing; the exhaust vent is located above the second blowing volute; the air inlet of the second blowing volute is arranged in the opposite direction of the air inlet of the first blowing volute. The opposite orientation of the air inlets of the two blowing volutes optimizes the internal air duct structure of the bathroom heater, leaving more space, which is conducive to improving the air outlet efficiency of the bathroom heater. At the same time, it makes the internal structure of the bathroom heater more compact, reduces the overall size of the bathroom heater, and has a wider range of applications and higher cost performance.

[0008] Furthermore, the ventilation port is provided on the side wall of the casing.

[0009] The present invention can be improved by stacking the first and second air outlet channels, each separated by a first partition. This arrangement improves air outlet efficiency while reducing the space occupied by the first and second air outlet channels, thus reducing the overall size of the bathroom heater and broadening its application range.

[0010] Furthermore, the first air outlet passage includes a first channel section and a second channel section, the first channel section and the second channel section being connected; the first channel section is an Archimedean spiral air duct, and the second channel section is a wedge-shaped air duct; the first blowing volute is disposed within the first channel section, and the air outlet is disposed above the second channel section. The first air outlet passage guides air through the combination of the Archimedean spiral air duct and the wedge-shaped air duct, resulting in low air loss and high air supply efficiency.

[0011] Furthermore, a heater is provided at the connection between the first channel section and the second channel section.

[0012] In some embodiments of the present invention, the exhaust port is rectangular, and the second channel section is a wedge-shaped air duct with a gradually narrowing width, arranged along the long side of the exhaust port. This arrangement can reduce airflow loss, increase airflow intensity, and achieve a more uniform airflow effect.

[0013] The present invention can be improved as follows: the exhaust port is connected to an air guide assembly, which includes an outer shell and an inner shell, the outer shell being trumpet-shaped and the inner shell being conical, and the outer shell being sleeved outside the inner shell, so that an annular airflow channel is formed between the outer shell and the inner shell. This arrangement can achieve an annular air outlet, which is more uniform, has a wider air outlet range, and higher ventilation efficiency.

[0014] Furthermore, diverter grilles are evenly distributed on the inner shell and arranged along the cone generatrix. The diverter grilles can improve the structural strength and also have a guiding effect, reducing airflow loss and improving air output strength.

[0015] Furthermore, the air guide assembly is further provided with a lamp, which is arranged in the inner shell and is located in the circular area enclosed by the annular airflow channel.

[0016] The present invention can be improved as follows: the second air outlet channel includes a third channel section and a fourth channel section, the third and fourth channel sections being connected; the third channel section is an Archimedean spiral air duct, and the fourth channel section is a linear air duct; the first blowing volute is disposed within the third channel section, and the fourth channel section is disposed directly opposite the ventilation port. The combination of the Archimedean spiral air duct and the linear air duct improves air supply efficiency while occupying less space, reducing the size of the bathroom heater and achieving a higher cost-effectiveness.

[0017] In the present invention, the air outlet of the second blowing volute is connected to the ventilation port via a ventilation channel; the ventilation channel includes a fifth channel section and a sixth channel section, which are connected to each other; the sixth channel section is an Archimedean spiral air duct, and the sixth channel section is a linear air duct; the second blowing volute is disposed within the fifth channel section, and the sixth channel section is disposed directly opposite the ventilation port. The combination of the Archimedean spiral air duct and the linear air duct improves air supply efficiency while occupying less space, reducing the size of the bathroom heater and achieving a higher cost-effectiveness.

[0018] Furthermore, the fourth channel section and the sixth channel section are arranged side by side; the second channel section of the first air outlet channel is arranged above the fourth channel section and the sixth channel section. This arrangement optimizes the internal space structure of the bathroom heater, reduces the size of the bathroom heater, and has a wide range of applications and a higher cost-effectiveness.

[0019] Furthermore, the fourth and sixth channel sections are separated by a second partition; an air guide is provided at the connection between the third and fourth channel sections, and an air guide is provided at the connection between the fifth and sixth channel sections. This arrangement reduces the mutual influence of air supply between the fourth and sixth channel sections when the first and second blowing volutes are simultaneously ventilating, thereby improving air supply efficiency.

[0020] The present invention has the following beneficial effects:

[0021] (1) The bathroom heater of the present invention is provided with an air inlet corresponding to the blowing volute and adopts a bidirectional blowing volute. The two blowing volutes can exchange air at the same time, which has a higher ventilation efficiency and leaves more room for improvement in the location of the exhaust port on the casing and the internal structure layout, which is beneficial to improving the air supply efficiency of the bathroom heater and reducing the size of the bathroom heater.

[0022] (2) The bathroom heater of the present invention improves the air duct structure, optimizes the layout position of the air duct structure inside the casing, improves the air supply efficiency of the air duct, makes the internal structure more compact, and has a smaller overall size. It is less restricted by the ceiling installation space and has a wider range of applications.

[0023] (3) The bathroom heater of the present invention improves the structure of the air outlet channel and adopts a wedge-shaped air duct that is adapted to the internal structure to make the air outlet more uniform. An air guide component is set at the air outlet to achieve annular uniform air outlet, obtain a better uniform air outlet effect, expand the blowing range, and improve the efficiency of blowing warm air.

DETAILED DESCRIPTION

[0045] Example 1

[0046] like Figure 1-10 The bathroom heater shown includes a casing 1 , a first blowing volute 2 , a second blowing volute 3 and a heater 4 .

[0047] The top of the housing 1 has a circular air inlet 102 and a rectangular air outlet 103, and a ventilation port 101 is provided on the side wall. With both the air inlet 102 and the air outlet 103 located on the top of the housing 1, air circulation within the bathroom's interior is achieved, improving ventilation efficiency and facilitating rapid heating within the bathroom. Furthermore, the placement of the air inlet 102 on the top of the housing 1 and the ventilation port 101 on the side wall circulate air within the bathroom and outside, creating an internal-external cycle for improved ventilation.

[0048] A first blowing volute 2 and a second blowing volute 3 are fixed within the casing 1. The first blowing volute 2 is a bidirectional blowing volute having two air outlets 201 and an air inlet 202. The air inlet 202 of the bidirectional blowing volute is arranged directly opposite the air inlet 102 on the casing 1, so that one air outlet 201 of the first blowing volute 2 is connected to the exhaust port 103 through the first air outlet channel 5, and one air outlet 201 of the first blowing volute 2 is connected to the ventilation port 101 through the second air outlet channel 6; the air outlet 201 of the second blowing volute 3 is connected to the ventilation port 101 through the ventilation channel 7. The air inlet 202 of the second blowing volute 3 is arranged in the opposite direction to the air inlet 202 of the first blowing volute 2, and the exhaust port 103 is arranged above the second blowing volute 3.

[0049] Specifically, the impeller of the first blowing volute 2 is provided with two layers of blades, wherein one layer of blades is arranged in a counterclockwise direction and the other layer of blades is arranged in a clockwise direction, so that the first blowing volute 2 can form air outlet in two directions and has two air outlets 201, one air outlet 201 is connected to the exhaust port 103 through the first air outlet channel 5, and the other air outlet 201 is connected to the ventilation port 101 through the second air outlet channel 6.

[0050] In this embodiment, the first air outlet duct 5 and the second air outlet duct 6 are stacked and separated by a first partition 8. The first air outlet duct 5 includes a first channel section 501 and a second channel section 502, which are connected. The first channel section 501 is an Archimedean spiral air duct, and the second channel section 502 is a wedge-shaped air duct. A heater 4 is provided at the junction of the first and second channel sections 501, 502, for supplying warm air to the exhaust port 103. The second air outlet duct 6 includes a third channel section 601 and a fourth channel section 602, which are connected. The third channel section 601 is an Archimedean spiral air duct, and the fourth channel section 602 is a straight air duct, located directly opposite the ventilation port 101. The first blowing volute 2 is located within the first and third channel sections 501, 601. The exhaust port 103 is rectangular and located above the second channel section 502. In order to make the air outlet 103 discharge air more evenly, the second channel section 502 is a wedge-shaped air duct with a gradually narrowing width and is arranged along the long side of the air outlet 103.

[0051] In the present invention, the ventilation channel 7 includes a fifth channel section 701 and a sixth channel section 702, and the fifth channel section 701 and the sixth channel section 702 are connected; the sixth channel section 702 is an Archimedean spiral air duct, and the sixth channel section 702 is a linear air duct, and is arranged directly opposite the ventilation port 101. The second blowing volute 3 is arranged in the fifth channel section 701. In order to obtain higher air supply efficiency, optimize the spatial structure inside the bathroom heater, and reduce the volume of the bathroom heater, the fourth channel section 602 and the sixth channel section 702 are arranged side by side, and the fourth channel section 602 and the sixth channel section 702 are separated by a second partition plate 9. The second channel section 502 of the first air outlet channel 5 is arranged above the fourth channel section 602 and the sixth channel section 702. An air guide 10 is provided at the connection between the third channel section 601 and the fourth channel section 602, and an air guide 10 is provided at the connection between the fifth channel section 701 and the sixth channel section 702. The air guide 10 is an arc-shaped plate, which minimizes the loss during the flow of air and improves the air supply efficiency.

[0052] The bathroom heater of the present invention is provided with an air inlet 102 corresponding to the blowing volute, and adopts a bidirectional blowing volute. This ensures ventilation intensity while leaving more room for improvement in the location of the exhaust port 103 on the housing 1 and the internal structural layout. The two blowing volutes can simultaneously ventilate, resulting in higher ventilation efficiency. At the same time, the internal airflow channel of the bathroom heater is optimized to minimize losses during airflow, while reducing the space occupied by the internal structure of the bathroom heater, thereby reducing the overall volume of the bathroom heater. It can be installed on ceilings of spaces of different sizes, has a wider range of applications, reduces the manufacturing cost of the bathroom heater, and is more cost-effective.

Specifically, the air guide assembly 11 includes an outer shell 1101 and an inner shell 1102, the outer shell 1101 is trumpet-shaped, and the inner shell 1102 is conical. The outer shell 1101 is sleeved on the outside of the inner shell 1102, so that an annular airflow channel 1103 is formed between the outer shell 1101 and the inner shell 1102. Through such an arrangement, an annular air outlet can be achieved, the air outlet is more uniform, the air outlet range is larger, and the ventilation efficiency is higher. In order to better achieve the effect of uniform air outlet, diverter grilles 1105 are evenly distributed on the inner shell, and the diverter grilles 1105 are arranged along the direction of the cone busbar. The diverter grilles 1105 can improve the structural strength and have a guiding effect at the same time. In this embodiment, the exhaust vent 103 is rectangular, and the airflow inlet 1104 of the air guide assembly 11 is also rectangular. The airflow inlet 1104 of the air guide assembly 11 is arranged corresponding to the exhaust vent 103; there are four diverter grilles 1105. Through this arrangement, the bathroom heater can achieve excellent air output uniformity, faster airflow exchange, and thus higher heating efficiency. In this embodiment, the air guide assembly 11 is also equipped with a lamp 12. The lamp 12 is arranged within the inner shell 1102 and is located within the circular area enclosed by the annular airflow channel 1103.

[0055] In the present invention, the second channel section 502 of the first air outlet channel 5 is a wedge-shaped air duct, which is compatible with the setting direction of the exhaust port 103 and the air guide component 11, so that the air flow enters the air guide component 11 as evenly as possible, thereby obtaining better air outlet uniformity.
