[0001] The present invention relates to the technical field of electrical equipment, and in particular to a wind wheel structure for a heater and the heater. Background Art

[0002] There are many types of heaters. Take the bathroom heater as an example. The bathroom heater is a small household appliance for the bathroom that combines multiple functions such as bathroom heating, bathroom ventilation, and decoration through a clever combination of a special PTC heater and a wind wheel duct. With the continuous advancement of technology and the continuous updating of customer needs, the quality and function of the bathroom heater are also constantly improving. While the bathroom heater industry is developing, some problems are also increasingly exposed. For example, the general floor height is only 3 meters. In order to pursue a larger space, the ceiling of the bathroom in the user's home generally does not reserve too much space. Generally, about 100mm of ceiling space is reserved. At present, the thickness of the general bathroom heater is also about 100mm. Due to the limitation of the size of the body, many users cannot install and use the bathroom heater; of course, there are also a small number of bathroom heaters on the market that are mainly thin and light, but due to the limitation of the size of the host, the functions are relatively simple, the performance is generally poor, and the user experience is not perfect.

[0003] That is to say, the heater in the prior art has the problem of poor performance. Summary of the invention

[0004] The main purpose of the present invention is to provide a wind wheel structure for a heater and a heater, so as to solve the problem of poor performance of the heater in the prior art.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a wind wheel structure for a heater is provided, comprising: a wind wheel body, which is cylindrical; supporting ribs, which are multiple and converge at one point, and the ends of the support ribs that are away from each other are connected to the wind wheel body, and the ends of the support ribs that converge to each other bulge toward the inside of the cylindrical wind wheel body, and a ventilation gap is formed between two adjacent support ribs, and at least one support rib is provided with a long slit, which extends along the extension direction of the support rib.

[0006] Furthermore, the height of one end of the supporting ribs converging to the inside of the cylindrical wind rotor body is greater than half of the axial length of the wind rotor body.

[0007] Furthermore, the height of one end of the supporting ribs converging toward the inside of the cylindrical wind rotor body is equal to the axial length of the wind rotor body.

[0008] Furthermore, the supporting ribs are divided into two sub-ribs by a long slit, the first ends of the two sub-ribs are respectively connected to the wind wheel body, the second ends of the two sub-ribs are converged and connected, and the cross-section of at least one sub-rib is one of polygonal, circular, and elliptical.

[0009] Furthermore, the cross section of the sub-rib is triangular.

[0010] Furthermore, the distance between the two sub-ribs gradually decreases in a direction approaching the first end of the sub-rib.

[0011] According to another aspect of the present invention, a heater is provided, comprising: a main body, the main body having an air outlet and a ventilation port, the air outlet and the ventilation port being located on the same or different surfaces of the main body; a volute, the volutes being multiple, the multiple volutes being arranged in sequence, and at least a portion of the volute wall of two adjacent volutes being shared; the above-mentioned wind wheel structure for the heater, the wind wheel structure being multiple, the multiple wind wheel structures being arranged in a one-to-one correspondence with the multiple volutes.

[0012] Further, a portion of the volute wall of at least one volute among the plurality of volutes is shared with the body.

[0013] Furthermore, the main body has a group of first and second side walls that are relatively arranged, the ventilation port is arranged on the first side wall, and an installation space is formed between the volute connected to the ventilation port and the second side wall. The heater also includes an electrical component, and the electrical component is arranged in the installation space; and / or the main body also has a group of third and fourth side walls that are relatively arranged, the installation space is arranged close to the third side wall relative to the fourth side wall, the heater also includes a heating module, the heating module is arranged close to the fourth side wall relative to the third side wall, and an air outlet is arranged at the main body corresponding to the heating module.

[0014] Furthermore, a plurality of volutes are arranged in sequence along the diagonal direction of the body.

[0015] Applying the technical solution of the present invention, a wind wheel structure for a heater includes a wind wheel body and supporting ribs, wherein the wind wheel body is cylindrical; there are multiple supporting ribs that converge at one point, and ends of the supporting ribs that are away from each other are connected to the wind wheel body, and one end of the supporting ribs that converge bulges toward the inside of the cylindrical wind wheel body, and a ventilation gap is formed between two adjacent supporting ribs, and at least one supporting rib is provided with a long slit, which extends along the extension direction of the supporting rib.

[0016] The wind rotor body is cylindrical, and such a setting plans the structural shape of the wind rotor body, improves the reliability of the use of the wind rotor body, and provides installation space for the support ribs, so that the support ribs can be set inside the cylindrical wind rotor body, ensuring the stability of the support ribs. There are multiple support ribs and they converge at one point. Such a setting is conducive to balancing the forces between the multiple support ribs to avoid the risk of deformation of the support ribs due to wind pressure during the operation of the wind rotor structure, thereby ensuring the structural stability of the support ribs. By connecting the ends of the support ribs that are far away from each other to the wind rotor body, the ends of the support ribs that converge to each other are raised toward the inside of the cylindrical wind rotor body, so that the support ribs are supported inside the wind rotor, which is conducive to increasing the strength of the structure formed by the multiple support ribs, thereby ensuring the strength of the wind rotor structure and ensuring that the wind rotor structure can operate stably. In addition, since the multiple support ribs are all strip-shaped, this is conducive to reducing the weight of the wind rotor structure and ensuring the lightweight of the wind rotor structure. By setting ventilation gaps and long slits, the supporting ribs of the wind rotor structure have less blocking effect on the wind during rotation, which greatly reduces the resistance encountered by the wind rotor structure during rotation, thereby improving the air permeability of the wind rotor structure, thereby increasing the air volume and maximum static pressure, so that the wind rotor structure can perform better.

[0017] In addition, since one end of the supporting ribs that converge together bulges toward the inside of the cylindrical wind wheel body, this greatly increases the size of the ventilation gap formed between two adjacent supporting ribs and the size of the long slits on the supporting ribs, further increasing the air passage area of ​​the wind wheel structure, increasing the air passage volume, and greatly increasing the air output of the wind wheel structure. At the same time, it is beneficial to reduce noise and improve user satisfaction. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0034] In order to solve the problem of poor performance of the heater in the prior art, the main purpose of the present invention is to provide a wind wheel structure for a heater and a heater.

[0035] like Figures 1 to 10 As shown, a wind wheel structure for a heater includes a wind wheel body 11 and supporting ribs 12, the wind wheel body 11 is cylindrical; there are multiple supporting ribs 12 and they converge at one point, the ends of the supporting ribs 12 that are away from each other are connected to the wind wheel body 11, and one end of the supporting ribs 12 that converges to each other bulges toward the inside of the cylindrical wind wheel body 11, and a ventilation gap 123 is formed between two adjacent supporting ribs 12, and at least one supporting rib 12 is provided with a long slit 122, and the long slit 122 extends along the extension direction of the supporting rib 12.

[0036] The wind rotor body 11 is cylindrical, and such a setting plans the structural shape of the wind rotor body 11, improves the reliability of the use of the wind rotor body 11, and provides installation space for the support ribs 12, so that the support ribs 12 can be arranged inside the cylindrical wind rotor body 11, ensuring the stability of the support ribs 12. There are multiple support ribs 12 and they converge at one point. Such a setting is conducive to balancing the forces between the multiple support ribs 12, so as to avoid the risk of deformation of the support ribs 12 due to wind pressure during the operation of the wind rotor structure, and ensure the structural stability of the support ribs 12. By connecting the ends of the support ribs 12 that are far away from each other to the wind rotor body 11, the ends of the support ribs 12 that converge to each other are raised toward the inside of the cylindrical wind rotor body 11, so that the support ribs 12 are supported inside the wind rotor, which is conducive to increasing the strength of the structure formed by the multiple support ribs 12, thereby ensuring the strength of the wind rotor structure and ensuring that the wind rotor structure can operate stably. In addition, since the multiple support ribs 12 are all strip-shaped, this is conducive to reducing the weight of the wind rotor structure and ensuring the lightweight of the wind rotor structure. By providing the ventilation gap 123 and the long slit 122, the supporting ribs 12 have less effect of blocking the wind during the rotation of the wind wheel structure, which greatly reduces the resistance encountered by the wind wheel structure during rotation, thereby improving the air permeability of the wind wheel structure, thereby increasing the air volume and maximum static pressure, so that the wind wheel structure can perform better.

[0037] In addition, since one end of the support ribs 12 that converge to each other bulges toward the inside of the cylindrical wind wheel body 11, this greatly increases the size of the ventilation gap 123 formed between two adjacent support ribs 12 and the size of the long slit 122 on the support rib 12, further increasing the air passage area of ​​the wind wheel structure, increasing the air passage volume, and greatly increasing the air output of the wind wheel structure. At the same time, it is beneficial to reduce noise and improve user satisfaction.

[0038] It should be noted that the side where the plurality of support ribs 12 bulges into the inside of the cylindrical wind rotor body 11 and the side where the ends of the support ribs 12 away from each other are connected to the wind rotor body 11 are located on two opposite sides of the wind rotor body 11.

[0039] Specifically, the height of one end of the support ribs 12 that converges toward the inside of the cylindrical wind rotor body 11 is greater than half of the axial length of the wind rotor body 11. This arrangement is conducive to ensuring the support effect of the support ribs 12 on the wind rotor body 11, and at the same time can reduce the wind resistance of the wind rotor structure during rotation, which is conducive to reducing noise and ensuring the wind output effect.

[0040] like Figure 8 As shown, the height of the one end where the support ribs 12 converge to the inside of the cylindrical wind rotor body 11 is equal to the axial length of the wind rotor body 11. This arrangement effectively reduces the weight of the wind rotor structure while ensuring that the wind rotor structure has sufficient strength, thereby ensuring the lightweight of the wind rotor structure. Since the air inlet of the wind rotor structure is located inside the cylindrical wind rotor body 11, the height of the one end where the support ribs 12 converge to the inside of the cylindrical wind rotor body 11 is equal to the axial length of the wind rotor body 11, making the structure of the support ribs 12 more reasonable, facilitating the assembly of the support ribs 12 and the wind rotor body 11, and further reducing the blocking of the air inlet by the support ribs 12, thereby reducing the resistance encountered when the wind rotor structure rotates, and ensuring the stability of the incoming air.

[0041] Specifically, the support ribs 12 are arc-shaped. The support ribs 12 are arranged in an arc shape, and the structural shape of the support ribs 12 is planned, which improves the reliability of the use of the support ribs 12, so that the structure formed by the multiple support ribs 12 is a hemispherical frame, which ensures the structural rationality of the support ribs 12 and increases the use efficiency of the support ribs 12.

[0042] Specifically, the above-mentioned wind wheel structure also includes a motor, which is arranged inside the wind wheel body 11 and the output shaft of the motor is drivingly connected to one end where multiple support ribs 12 converge. Since the end where the support ribs 12 converge is raised toward the inside of the cylindrical wind wheel body 11, this leaves space for the motor to accommodate the motor, ensuring reliability in use. At the same time, the support ribs 12 will not affect the operation of the motor, so that the motor starts and drives the wind wheel body 11 to rotate through the support ribs 12, ensuring that the wind wheel structure can operate stably.

[0043] like Figure 4 and Figure 6As shown, the support rib 12 is divided into two sub-ribs 121 by a long slit 122, the first ends of the two sub-ribs 121 are respectively connected to the wind rotor body 11, and the second ends of the two sub-ribs 121 are converged and connected. This arrangement makes the end of the long slit 122 on the support rib 12 away from the convergence point extend to the end of the support rib 12, so that the first ends of the two sub-ribs 121 are separated and respectively connected to the wind rotor body 11; the end of the long slit 122 close to the convergence point is spaced from the convergence point, that is, the second ends of the two sub-ribs 121 are converged and connected. This arrangement increases the connection position of the support rib 12 and the wind rotor body 11, ensures the connection strength of the support rib 12 and the wind rotor body 11, avoids the risk of the support rib 12 and the wind rotor body 11 being separated during operation, and ensures the connection stability. Since the end of the long slit 122 close to the convergence point does not extend to the convergence point, the end where the multiple support ribs 12 converge is a structure with a connection area, so that the convergence end of the multiple support ribs 12 has sufficient structural strength to reduce the possibility of deformation of the support ribs 12 due to excessive wind pressure or excessive rotation speed; in addition, the connection area reserves a connection position for the motor to ensure the reliability of the driving connection between the motor and the connection area.

[0044] It should be noted that there are five supporting ribs 12, and each supporting rib 12 includes two sub-ribs 121. Of course, different numbers of supporting ribs 12 may be provided according to actual conditions.

[0045] Specifically, the cross section of at least one sub-rib 121 is one of polygonal, circular, and elliptical. In other words, the specific shape of the sub-rib 121 can be set according to actual conditions.

[0046] like Figure 4 As shown, the cross section of the sub-rib 121 is triangular. One of the corners of the triangle faces the direction of the bulge of the support rib 12. This arrangement makes the sub-rib 121 an arc-shaped triangular prism, so that the two sides of the corner facing the direction of the bulge of the support rib 12 can serve as wind guide surfaces, while ensuring the strength of the sub-rib 121, ensuring that the sub-rib 121 can play a role in guiding wind, and reducing the wind resistance of the sub-rib 121.

[0047] Specifically, the distance between the two sub-ribs 121 gradually decreases in the direction close to the first end of the sub-rib 121. This arrangement makes the ventilation area of ​​the long slit 122 gradually decrease in the direction away from the first end of the sub-rib 121.

[0048] like Figure 1 , Figure 2 and Figure 3As shown, the heater includes the above-mentioned wind wheel structure for the heater. The heater also includes a body 20, a volute 30 and the above-mentioned wind wheel structure, the body 20 has an air outlet 21 and a ventilation port 22, the air outlet 21 and the ventilation port 22 are located on the same or different surfaces of the body 20; there are multiple volutes 30, the multiple volutes 30 are arranged in sequence, and at least a part of the volute wall of two adjacent volutes 30 is shared, there are multiple wind wheel structures, and the multiple wind wheel structures are arranged one by one with the multiple volutes 30.

[0049] By sharing at least a portion of the volute wall of two adjacent volutes 30, the size of the volute 30 can be increased as much as possible without increasing the overall size of the body 20, thereby increasing the ventilation area of ​​the volute 30 to increase the air volume, thereby ensuring that the heater is miniaturized and the air outlet effect can meet the user's requirements. Multiple wind wheel structures are arranged in a one-to-one correspondence with multiple volutes 30, so that the volute 30 plays a role in guiding the wind, so that the wind generated by the wind wheel structure is discharged through the guidance of the corresponding volute 30.

[0050] It should be noted that in the present application, there are two wind wheel structures, two volutes 30, and the outlets of the two volutes 30 correspond to the air outlet 21 and the ventilation port 22 respectively. The volute 30 corresponding to the air outlet 21 has a heating air duct, and the volute 30 corresponding to the ventilation port 22 has a ventilation air duct.

[0051] The heater of the present application is a thin and light multifunctional bathroom heater, with a simple overall structure and streamlined parts. The main body 20 is in the shape of a cuboid, and the length of the cuboid is 520 mm, the width is 300 mm, and the height is 74 mm. This makes the overall size of the heater smaller, ensures miniaturization, and enables the heater to be installed in a smaller space, increasing the application range of the heater and making it more widely used. In addition, the heater of the present application has functions such as blowing, ventilation, heating, drying, lighting, night light, negative ion purification, and wind direction adjustment. It solves the problem that the current building floor height is generally low, the ceiling height is insufficient, resulting in the inability to install the heater, or the problem that the performance is reduced and the heating effect is greatly reduced due to the pursuit of a thin and light body. In addition, the heater of the present application is simple in structure and has a small number of parts, is relatively simple in assembly, and is easy to produce, which can effectively increase the production capacity of the product, thereby reducing production costs.

[0052] The heater of the present application reduces the overall volume and ensures miniaturization without reducing the functions of the heater. By adjusting the internal layout structure of the heater, the size of the body is further compressed and the performance is improved, while also having multi-functional expandability.

[0053] like Figure 3As shown, part of the volute wall of at least one volute 30 among the multiple volutes 30 is shared with the body 20. As shown in the figure, part of the volute wall of the volute 30 connected to the ventilation port 22 is shared with the body 20, which can also ensure that the size of the volute 30 is increased as much as possible without increasing the overall size of the body 20, thereby increasing the ventilation area of ​​the volute 30 to increase the air volume.

[0054] like Figure 2 and Figure 3 As shown, a plurality of volutes 30 are arranged in sequence along the diagonal direction of the body 20. This arrangement plans the arrangement of the plurality of volutes 30, improves the reliability of the use of the volutes 30, and at the same time leaves an installation space for the structure of the body 20. The body 20 has a set of first side walls 23 and second side walls 24 arranged opposite to each other, the ventilation port 22 is arranged on the first side wall 23, and the above-mentioned installation space is formed between the volute 30 and the second side wall 24 connected to the ventilation port 22. The heater also includes an electrical component, which is arranged in the installation space.

[0055] Specifically, the body 20 also has a set of third side walls 25 and fourth side walls 26 arranged opposite to each other, the installation space is arranged near the third side wall 25 relative to the fourth side wall 26, the heater further comprises a heating module 100, the heating module 100 is arranged near the fourth side wall 26 relative to the third side wall 25, and the body 20 is provided with an air outlet 21 corresponding to the heating module 100. This arrangement enables the wind wheel structure corresponding to the air outlet 21 to work, and the corresponding volute 30 guides the wind generated by the wind wheel structure to the air outlet 21, and then is heated by the heating module 100 to form hot air, which is discharged from the air outlet 21 to achieve the heating function.

[0056] It should be noted that the heating module 100 may be a PTC heater or an electric heating tube. In the present application, the heating module 100 is a PTC heater.

[0057] It should be noted that the electrical components include an LED driving power supply 40, a motor starting capacitor 50, a control PCB board 60 and a terminal 70 which are electrically connected to each other. The terminal 70 is arranged on the third side wall 25 corresponding to the installation space, the first side of the LED driving power supply 40 is connected to the third side wall 25, and the side of the LED driving power supply 40 opposite to the first side is connected to the motor starting capacitor 50. The control PCB board 60 is vertically placed in the installation space and is attached to the second side wall 24, and the control PCB board 60 is located on the side of the motor starting capacitor away from the LED driving power supply 40.

[0058] like Figure 7 and Figure 8As shown, the heater also includes a flow guide structure 80, which is connected to the outlet of one of the volutes 30. The flow guide structure 80 has an arc-shaped air guide surface, which extends from the outlet of the volute 30 to the air outlet 21. Since the volute 30 corresponding to the air outlet 21 has a heating air duct, the flow guide structure 80 is arranged at the outlet of the volute 30, so that the wind at the outlet of the heating air duct is diverted by the flow of the arc-shaped air guide surface. The PTC heater is arranged at the outlet of the flow guide structure 80. The air is accelerated by the wind wheel structure and diverted through the arc-shaped air guide surface. After blowing to the PTC heater, it is heated and blown out as warm air, which saves the original air duct diversion parts of the conventional bathroom heater structure, reduces the number of parts of the whole machine, reduces the weight of the whole machine, greatly improves the production efficiency, and can ensure the heating efficiency at the same time.

[0059] like Fig. 9 and Fig.10 As shown, the heater also includes a negative ion emitter 90, and at least one side surface of the guide structure 80 has a through hole 82, and the negative ion emitter 90 extends into the interior of the guide structure 80 through the through hole 82. The guide structure 80 has a buckle 81, and when the negative ion emitter 90 extends into the interior of the guide structure 80 through the through hole 82, the buckle 81 is engaged with the negative ion emitter 90 to limit and fix the negative ion emitter 90 on the guide structure 80, thereby avoiding the situation where the negative ion emitter 90 and the guide structure 80 shake or separate during operation, and ensuring assembly stability. In this way, the negative ion purification function of the heater is realized, so that the negative ions generated by the negative ion emitter 90 are mixed with air in the guide structure 80 and then blown out.

[0060] It should be noted that a grille is also provided at the air outlet 21 to evenly guide the wind to achieve a uniform wind effect.
