Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to an air guide component and a heater equipped with the air guide component. Background Art

[0002] With the improvement of the quality of modern home life, heaters, as important equipment for winter heating, play a vital role in ensuring indoor warmth and improving living comfort. The main function of the heater is to generate heat through the heating element and transport the hot air to the indoor space through a fan or impeller, thereby increasing the indoor temperature. In this process, the volute and volute tongue, as key components, have a direct and significant impact on the performance of the heater. However, the side wall structures of the volute and volute tongue of the heaters commonly seen on the market are often too simple and mainly straight, which limits the performance of the heater in many aspects.

[0003] First, from the perspective of aerodynamics, the side walls of the volute and the volute tongue cannot effectively guide the rotating wind output by the wind wheel. The airflow generated by the wind wheel during rotation has complex rotation and vortex characteristics, and the straight surface cannot fully utilize these characteristics, resulting in unnecessary vortex and backflow of the airflow inside the volute. This not only reduces the air output efficiency of the heater, but may also lead to energy waste and unstable operation of the heater.

[0004] Secondly, the straight-face design increases wind resistance, which in turn affects the performance and energy consumption of the heater. When the airflow passes through the straight face, due to the large angle between the straight face and the airflow, the airflow needs to consume more energy to overcome the resistance, resulting in increased wind resistance. This not only reduces the air output efficiency of the heater, but may also cause the fan or impeller to consume more energy to drive the airflow, thereby increasing the energy consumption of the heater. In today's increasingly tight energy situation, reducing energy consumption has become an important development direction for home appliances.

[0005] In addition, the straight-face design may also increase noise and affect user comfort. Due to the increase in wind resistance, the airflow may generate turbulence and vibration when flowing inside the volute, which in turn generates noise. Noise not only reduces user comfort, but may also have an adverse effect on user health. In today's pursuit of high-quality life, reducing noise has become an important evaluation indicator for home appliances. Utility Model Content

[0006] One of the primary purposes of the present invention is to solve at least one of the above problems and to provide an air guide assembly and a heater.

[0007] In order to meet the various purposes of the utility model, the utility model adopts the following technical solutions:

[0008] To meet one of the purposes of the utility model, an air guide component is provided, including a volute and a volute tongue, the volute includes an air guide plate, the air guide plate and the volute tongue are arranged opposite to each other to define an air guide channel, the air guide plate is provided with an air guide protrusion to divide the air guide channel into a cyclone section and an air outlet section, the volute tongue includes an air induction plate, the air induction plate is one of the side walls of the air outlet section, and the air guide protrusion is arranged to protrude toward the air induction plate.

[0009] Furthermore, the wind guide plate also includes a front wind guide plate and a rear wind guide plate, the front wind guide plate and the rear wind guide plate are respectively arranged on the front and rear sides of the wind guide protrusion, and the rear wind guide plate and the air induction plate define the air outlet section.

[0010] Specifically, the air guide front plate and the air guide rear plate are respectively arranged tangent to the air guide protrusions.

[0011] In one embodiment, the wind guiding protrusion is an arc protrusion with an angle ≥ 90°.

[0012] Furthermore, the volute tongue also includes a wind-inducing protrusion and a downwind plate, and the downwind plate and the wind-inducing plate are respectively arranged on the front and rear sides of the wind-guiding protrusion, and the downwind plate and the wind-guiding front plate define the cyclone section.

[0013] In one embodiment, the downwind plate is arranged tangentially to the wind-inducing protrusion.

[0014] In one embodiment, the cyclone section defines an air guide inlet of the air guide channel, the air outlet section defines an air guide outlet of the air guide channel, and an angle between a plane where the air guide inlet is located and a plane where the air guide outlet is located is ≤45°.

[0015] Specifically, the air guiding rear plate is arranged tangent to the air guiding protrusion.

[0016] In one embodiment, the air-inducing protrusion is an arc protrusion with an angle of 30°-60°.

[0017] A heater is provided to meet one of the purposes of the utility model, including a shell and a wind wheel, a heating component, a mounting frame installed in the shell, and an air guide component as described in any one of the previous purposes, the wind wheel is installed in the cyclone section, the mounting frame is provided with a heating channel, the heating channel is connected to the air outlet section, the heating component is installed in the heating channel, the shell is provided with an air inlet and an air outlet, the air inlet is connected to the cyclone section, and the air outlet is connected to the heating channel.

[0018] Compared with the prior art, the present invention has many advantages, including but not limited to:

[0019] First, the air guide protrusion of the air guide assembly of the utility model divides the air guide channel into a cyclone section and an air outlet section. By reasonably setting the air guide protrusion, the air flow in the cyclone section is further optimized. The air in the cyclone section can form an orderly swirl under the rotation of the volute. This swirl not only reduces unnecessary energy loss, but also enhances the mixing effect of the air, making the temperature distribution of the air more uniform. The air outlet section allows the air to flow out more directly and quickly without excessive obstruction and turning, which greatly reduces the resistance to air flow and improves the air outlet efficiency. At the same time, this also enables the heater to deliver warm air to the room in a shorter time, improving the user's comfort.

[0020] Secondly, the air guide protrusion is arranged to protrude toward the air guide plate, so that the air in the air outlet section has a clearer guide when it flows out, thereby reducing wind resistance. This not only ensures that the air flows in the predetermined direction, but also reduces wind resistance. The air flows more smoothly and orderly in the air guide channel. This helps to reduce the generation of turbulence, making the air flow more stable and continuous when it flows out, and improving the use effect of the heater.

[0021] In addition, as mentioned earlier, the cyclone section and the air outlet section help reduce the turbulence and eddies generated during the air flow. These turbulence and eddies are one of the main sources of noise, so by reducing their generation, the noise level of the heater can be effectively reduced. The air guide ridges and air guide plates also help reduce wind resistance noise. The reduction in noise not only improves the performance and service life of the heater, but also provides users with a quieter and more comfortable use environment.

[0034] Those skilled in the art will understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of ordinary technicians in the field to which the utility model belongs. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as the meaning in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as here.

[0035] The utility model provides an air guide component, the air guide protrusion of the air guide component divides the air guide channel into a cyclone section and an air outlet section, so as to effectively guide the flow of air, so that the air can flow out more directly and efficiently, and the flow of air in the air guide channel is smoother and more orderly, thereby reducing the noise generated during the air flow.

[0036] In the present invention, in order to facilitate the discussion of the air guide assembly 100, the present invention will discuss the air guide assembly 100 in conjunction with the heater 200. The air guide assembly 100 is one of the components of the heater 200, but this should not be understood as a limitation on the application of the air guide assembly 100.

[0037] In a typical embodiment of the present invention, Figure 3 and Figure 4 The heater 200 includes a shell 210, a wind wheel 220, a heating component 230, a motor 240, an air guide component 100, a mounting bracket 250 and a control unit (not shown). The wind wheel 220, the heating component 230, the motor 240, the air guide component 100 and the mounting bracket 250 are arranged in the shell 210, and the control unit is electrically connected to the heating component 230 and the motor 240 respectively.

[0038] Specifically, the housing 210 has an air duct formed therein. Figure 1 and Figure 2 The air duct includes an air inlet 211 and an air outlet 212 opened on the housing 210. Figure 4 and Figure 5 The air guide assembly 100 includes a volute 110 and a volute tongue 120, and the volute 110 and the volute tongue 120 cooperate to form an air guide channel 130. The mounting frame 250 is provided with a heating channel 251, and the air guide channel 130 is connected with the heating channel 251 to form the air duct. The air guide channel 130 is arranged near the air inlet 211, and the heating channel 251 is arranged near the air outlet 212.

[0039] The wind wheel 220 is disposed in the wind guide channel 130, the output shaft of the motor 240 is plugged into the wind wheel 220, and the control unit controls the motor 240 to drive the wind wheel 220 to rotate through the motor 240 to form cold air, and the cold air is output toward the heating channel 251. In one embodiment, the control unit is a control chip or a single-chip microcomputer.

[0040] Combination Figure 3 and Figure 5The heating component 230 is disposed in the heating channel 251, and the control unit controls the heating component 230 to work so that the heating component 230 generates heat. When the cold air generated by the wind wheel 220 flows into the heating channel 251, the heat generated by the heating component 230 heats the cold air, so that the cold air becomes hot air, and the hot air is output to the outside of the heater 200 through the air outlet 212 to increase the temperature of the external environment.

[0041] In this embodiment, the volute tongue 120 is disposed in the volute case 110, and the volute tongue 120 cooperates with the volute case 110, so that the heater 200 can output hot air to the outside world well and increase the outside temperature.

[0042] Specifically, the volute 110 is used to guide the wind rotation formed by the wind wheel 220, so that the hot air output by the heater 200 can be evenly output from the air outlet 212, to ensure that the hot air can be effectively and evenly distributed to the outside, for example, to every corner of the indoor environment, thereby improving the heating efficiency.

[0043] The volute tongue 120 is used to reduce the backflow of wind generated by the wind wheel 220 in the wind guide channel 130 of the volute 110, so as to reduce the noise of the heater 200 during operation, so that the heater 200 can maintain a low operating noise while providing hot air, creating a more comfortable use environment for users.

[0044] Therefore, the volute 110 and the volute tongue 120 cooperate with each other to play an important role in guiding airflow, reducing noise and optimizing aerodynamic performance in the heater 200, providing users with a more efficient, comfortable and quiet use experience.

[0045] In a typical embodiment of the present invention, Figure 8 The volute 110 includes an air guide plate 111 and a pair of end covers 112. The pair of end covers 112 are respectively arranged at both ends of the air guide plate 111 in a vertical direction. The air guide plate 111 and the pair of end covers 112 are surrounded to form an installation cavity. Figure 6 and Figure 7 The volute tongue 120 is disposed in the installation cavity. The volute tongue 120 is disposed opposite to the air guide plate 111 . The volute tongue 120 cooperates with the air guide plate 111 to define the air guide channel 130 .

[0046] Specifically, combined Figure 7The wind guide plate 111 includes a wind guide front plate 1111, a wind guide protrusion 1112 and a wind guide rear plate 1113, and the wind guide front plate 1111, the wind guide protrusion 1112 and the wind guide rear plate 1113 are sequentially connected. The volute tongue 120 includes a downwind plate 121, a wind inducing protrusion 122 and a wind inducing plate 123, and the downwind plate 121, the wind inducing protrusion 122 and the wind inducing plate 123 are sequentially connected.

[0047] The air guide channel 130 is divided into a cyclone section 131 and an air outlet section 132 in sequence from the air inlet 211 to the air outlet 212. The cyclone section 131 is connected to the air outlet section 132, the cyclone section 131 is connected to the air inlet 211, and the air outlet section 132 is connected to the heating channel 251. The air guide front plate 1111 is arranged opposite to the windward plate 121 to define the cyclone section 131; the air guide rear plate 1113 is arranged opposite to the wind inducing plate 123 to define the air outlet section 132. The wind wheel 220 is arranged in the cyclone section 131, and the wind wheel 220 rotates to suck the external air into the air channel through the air inlet 211, and the wind wheel 220 rotates and accelerates the air to form wind, and outputs the wind to the heating channel 251 through the air outlet section 132.

[0048] The wind guide front plate 1111 is an arc plate. When the wind wheel 220 rotates to form wind, the wind can flow along the wind guide front plate 1111 to the air outlet section 132. It can be understood that the arc plate-shaped wind guide front plate 1111 can guide the wind formed by the wind wheel 220 to flow to the air outlet section 132, thereby increasing the flow rate of the wind, and the wind will not be blocked by the wind guide front plate 1111, thereby reducing noise.

[0049] In this embodiment, the wind guide front plate 1111 is arranged tangent to the wind guide protrusion 1112, so that the wind flowing along the wind guide front plate 1111 will not be blocked by the wind guide protrusion 1112, that is, the wind resistance is reduced, and the flow rate of the wind can also be increased, so that the wind can quickly flow from the spinning wind section 131 to the air outlet section 132.

[0050] The wind guide protrusion 1112 is a circular arc protrusion, so that the wind flowing through the wind guide protrusion 1112 from the spinning wind section 131 can smoothly flow through the wind guide protrusion 1112 without being blocked by the wind guide protrusion 1112. In this embodiment, the angle of the wind guide protrusion 1112 is ≥90°, that is, the angle of the wind guide protrusion 1112 is an obtuse angle. It can be understood that the obtuse angle is relatively gentle, and the corresponding wind guide protrusion 1112 is also relatively gentle, so that the wind flowing through the wind guide protrusion 1112 will not be blocked by the wind guide protrusion 1112, so that the wind passes through the wind guide protrusion 1112.

[0051] The downwind plate 121 is a flat plate structure, and the downwind plate 121 and the wind guide front plate 1111 form the cyclone section 131. The downwind plate 121 faces the air inlet 211, so as to guide the external air into the wind guide channel 130. The downwind plate 121 is arranged tangentially to the wind inducing protrusion 122, so that no corner or step is formed between the downwind plate 121 and the wind inducing protrusion 122, so that the downwind plate 121 can guide the wind smoothly, and the wind flowing from the downwind plate 121 to the wind inducing protrusion 122 will not be blocked, so as to improve the wind guiding efficiency.

[0052] The wind inducing protrusion 122 is an arc protrusion, so that the wind flowing through the wind inducing protrusion 122 from the whirlwind section 131 can smoothly flow through the wind inducing protrusion 122 without being blocked by the wind inducing protrusion 122. In this embodiment, the angle of the wind inducing protrusion 122 is 30°-60°, and the wind inducing protrusion 122 is arranged close to the wind wheel 220, so that the wind inducing protrusion 122 avoids the wind flowing to the air outlet section 132 through the wind inducing front plate 1111, so that the wind guided by the wind inducing front plate 1111 will not flow to the wind inducing protrusion 122, so as to reduce wind resistance.

[0053] In one embodiment, the downwind plate 121 is further arranged tangent to the wind guiding protrusion 1112 , so that the wind flowing through the downwind plate 121 to the air outlet section 132 is blocked by the wind guiding protrusion 1112 to reduce wind resistance.

[0054] In a typical embodiment of the utility model, the air induction plate 123 is an arc-shaped plate, and the air induction plate 123 is used to guide the wind flowing from the air induction front plate 1111 to the air outlet section 132, so that the wind can quickly flow into the heating channel 251. In this embodiment, the air induction protrusion 122 is arranged closer to the wind wheel 220 than the air induction protrusion 1112, and the air induction protrusion 1112 is arranged to protrude toward the air induction plate 123, so that the wind guided to the air outlet section 132 through the air induction front plate 1111 will not pass over the air induction protrusion 122, so that the wind guided through the air induction front plate 1111 can be completely guided by the air induction plate 123, thereby improving the air outlet efficiency.

[0055] In one embodiment, in combination Figure 5 The air outlet section 132 of the air guide channel 130 is connected to the heating channel 251, and the air guide plate 123 is also connected to one of the side walls (called the first side wall 252) of the heating channel 251. In this embodiment, the air guide plate 123 is arranged tangent to the first side wall 252, so that the wind guided by the air guide plate 123 can flow smoothly into the heating channel 251 without being blocked by the first side wall 252 of the heating channel 251, thereby improving the air outlet efficiency.

[0056] In a typical embodiment of the present invention, Figure 7 , the wind guide rear plate 1113 and the air induction plate 123 define the air outlet section 132. The wind guide rear plate 1113 is arranged tangent to the wind guide protrusion 1112 to gradually expand the width of the air outlet section 132, so that the wind flowing into the air outlet section 132 can diffuse into the heating channel 251, thereby improving the heating efficiency of the heating component for the cold air. Because the air induction protrusion 122 is arranged closer to the wind wheel 220 than the wind guide protrusion 1112, the length of the air induction plate 123 connected to the air induction protrusion 122 is greater than the length of the wind guide rear plate 1113 connected to the wind guide protrusion 1112. In one embodiment, the wind guide rear plate 1113 is also arranged tangent to the wind induction protrusion 122, so that the wind guide rear plate 1113 can also guide the wind guided by the downwind plate 121.

[0057] The wind guide front plate 1111 and the wind down plate 121 constitute a cyclone section 131. It can be understood that the end of the wind guide front plate 1111 close to the air inlet 211 (called the first end 113) and the end of the wind down plate 121 close to the air inlet 211 (called the second end 1211) constitute the inlet of the wind guide channel 130 (the inlet is called the wind guide inlet). The wind guide rear plate 1113 and the wind guide plate 123 constitute the air outlet section 132. It can be understood that the end of the wind guide rear plate 1113 close to the heating channel 251 (called the third end 114) and the end of the wind guide plate 123 close to the heating channel 251 constitute the outlet of the wind guide channel 130 (the outlet is called the wind guide outlet).

[0058] In this embodiment, the angle between the plane where the wind guide inlet is located and the plane where the wind guide outlet is located is ≤45°, so that the internal turning of the wind guide channel 130 is not too sharp, thereby avoiding the wind entering the wind guide channel 130 from turning sharply, thereby reducing wind resistance. Figure 7 It can be seen that the angle between the imaginary line (called the first line) between the first end 113 and the second end 1211 and the imaginary line (called the second line) between the third end 114 and the fourth end 1231 is the angle between the plane where the air guide inlet is located and the plane where the air guide outlet is located.

[0059] In summary, the heater of the present invention reasonably designs the structure of the volute and the volute tongue so that the wind entering the air guide channel will not be subject to large wind resistance, so that the wind can flow out of the air guide channel quickly and reduce wind noise.
