Description

Technical Field

[0001] The utility model relates to the field of air supply equipment, in particular to an air supply component and an electrical appliance using the same. Background Art

[0002] The existing air supply equipment includes a shell, an air supply assembly arranged at the bottom of the shell, and a fan arranged in the shell. The airflow generated by the fan is transported outwards through the air supply assembly. The air supply assembly includes a panel with an air duct, an air guide arranged on the panel, and a motor that drives the air guide to rotate. The air guide is swingably installed at the air outlet of the air duct to divert and guide the hot air to ensure that the hot air is transported to a preset area. The existing motors are all arranged on the side of the air guide. The motor is connected to the end wall of the air guide through a rotating shaft, which effectively controls the air guide to swing at a preset angle. The contour of the air guide matches the contour of the air outlet, resulting in the airflow flowing out from the ends of the air outlet and spreading outwards. The airflow cannot be guided to the preset area by contact due to the air guide being too short and misaligned with the air guide. Especially in heater products, the hot air will suffer from transmission loss due to poor transmission and guidance effect, affecting the heating efficiency of the preset space and increasing energy consumption.

[0003] In addition, in order to reserve installation space for the motor, the length of the air guide is limited, resulting in a large distance between the air guide and the edge of the panel, affecting the aesthetics. Utility Model Content

[0004] In order to address the deficiencies of the prior art, the utility model provides an air supply assembly and an electrical appliance using the same. An end guide portion is provided at the end of the baffle. The end guide portion can not only effectively guide the airflow flowing out from the end of the air outlet, ensuring that the airflow can be transported to a preset area, but also shield the motor, reduce the distance between the end edge of the baffle and the edge of the panel, and improve the aesthetics.

[0005] The present invention is realized in the following manner: an air supply assembly, comprising a panel with an air duct, an air guide member arranged on the panel, and a motor for driving the air guide member to rotate, the air guide member being swingably mounted at the air outlet of the air duct, the air guide member comprising a baffle, the baffle extending outwardly along its length direction to form an end guide portion, the motor being arranged at the end side of the air guide member and being shielded by the end guide portion, the swinging path of the baffle avoiding the motor so that the airflow flowing out of the end of the air outlet is transported to a preset area through the end guide portion. An end guide portion is arranged at the end of the baffle, and the baffle can avoid the motor when swinging, so that the end guide portion can be used to effectively guide the airflow flowing out of the end of the air outlet to ensure that the airflow can be transported to the preset area, and the end guide portion can be used to completely shield the motor and the rotating shaft connected between the motor and the air guide member when the baffle blocks the air outlet, and the distance between the end edge of the baffle and the edge of the panel is reduced by increasing the length of the baffle, thereby improving the aesthetics.

[0006] Preferably, the air guide is rotatably mounted at the air outlet via a rotating shaft, so that the air guide can swing and switch between a closed position that blocks the air outlet and blocks the motor and an open position that exposes the air outlet, with the rotating shaft as the center. The swingable angle of the air guide when switching between the closed position and the open position is A, and A ≥ 90°. The air guide has the functions of guiding the airflow and blocking the air outlet. By increasing the swingable angle of the air guide, the airflow delivery range is expanded to meet the use requirements. The air guide is connected to the air outlet via a rotating shaft, which not only plays a role in connecting and positioning the air guide, facilitating the connection between the rotating shaft and the motor, but also guides the swinging path of the air guide, thereby improving the control convenience and reliability.

[0007] Preferably, a protrusion with a mounting cavity is provided on one side of the air duct end wall, and the motor is inserted and installed in the mounting cavity, and an avoidance gap is formed on the other side of the air duct end wall for the end guide to swing. The protrusion is provided in the air duct end wall, which can not only provide installation space for the motor through the internal mounting cavity, but also reduce the impact on the air flow velocity in the air duct by being hidden in the air duct end wall. The protrusion is provided on one side of the air duct end wall, so that an avoidance gap is formed on the other side of the air duct end wall. The end guide can swing at a large angle through the avoidance gap with the rotating shaft as the center, which not only expands the air supply range and effectively prevents the protrusion from hindering the swing of the end guide, but also can use the space under the protrusion to increase the length of the baffle to ensure that the extended end guide can completely cover the protrusion when the air guide member is switched to the closed position.

[0008] Preferably, the air guide member includes a guide plate arranged in the middle section of the baffle, and the guide plate close to the end guide portion is connected to the drive shaft of the motor through a rotating shaft, so that the swing path of the air guide member avoids the protrusion. The guide plate is arranged perpendicular to the baffle, and the guide plate at the end is connected to the drive shaft of the motor through a rotating shaft, so that the air guide member can swing freely within a preset angle range under the drive of the motor, thereby realizing switching between the closed position and the open position, and adjusting the airflow delivery direction by swinging when in the open position, ensuring that the airflow is delivered to the preset area. The projection of the guide plate along the axis of the air duct is staggered with the protrusion to ensure that the guide plate does not come into contact with the protrusion when swinging.

[0009] Preferably, the guide plates are equidistantly spaced along the length direction of the baffle. When the air guide is in the open position, the guide plates are equidistantly spaced and simultaneously play a role in steering and guiding the airflow in each area of the air outlet, ensuring that the airflow can be turned synchronously and reducing wind resistance by limiting the number of guide plates.

[0010] Preferably, the guide plates are connected by a top plate, and the top plate and the vertical projection of the protrusion are offset from each other. The top plate is used to connect the guide plates, and the ends of the guide plates are respectively connected to the top plate and the baffle, which effectively improves the structural strength of the air guide, ensures that the guide plates always remain perpendicular to the baffle, and prevents the ends of the guide plates from deforming when pushed by airflow.

[0011] Preferably, the raised portion is exposed on the sidewall of the avoidance notch to form a limiting surface. When the air guide member swings to the open position, it contacts the limiting surface to prevent excessive swing of the air guide member. The limiting surface is formed by the surface of the raised portion facing the avoidance notch, and acts as a contact and limiter for the end-mounted guide portion, thereby limiting the swing range of the air guide member and ensuring that the air guide member swings within a preset angle range.

[0012] Preferably, the raised portion is formed as an integral part with the panel, and an assembly port for disassembling and assembling the power supply unit is provided on the outer end surface of the raised portion facing away from the air duct, and the inner end surface of the raised portion facing the air duct is sealedly connected to the inner wall of the air duct to limit leakage of air in the air duct. The raised portion and the panel are formed by integral processing, which effectively eliminates the gap between them and ensures the sealing of the inner wall of the air duct. It not only ensures smooth flow of air by reducing wind resistance, but also prevents loss of air leakage, improves airflow transmission efficiency, and avoids the motor being affected by factors such as temperature, humidity, and dust of the air flow. The assembly port is provided on the outer end surface of the raised portion facing away from the air duct, which not only facilitates the disassembly and assembly of the motor and improves assembly efficiency, but also avoids the air duct and ensures that the inner wall of the air duct is smooth and flat.

[0013] Preferably, the motor comprises a cylindrical housing, an eccentrically arranged drive shaft, and a terminal box disposed on the side of the housing away from the drive shaft. The motor is deflected with its drive shaft as the center, away from the avoidance notch, thereby reducing the height of the mounting cavity and increasing the swingable angle of the air guide. The terminal box is disposed on the outer peripheral wall of the housing away from the drive shaft. The inner contour of the mounting cavity matches the contour of the motor, thereby securing and limiting the rotation of the motor and thereby improving the swing accuracy of the air guide.

[0014] Preferably, the motor has a center plane passing through the stator axis and the center line of the terminal box, the angle between the center plane and the vertical plane is B, 50°≤B≤65°, and the terminal box is arranged in the upper oblique area of the outer peripheral wall of the shell away from the avoidance gap, which can effectively reduce the height of the motor and limit the width of the radial cross-section of the motor, reasonably utilize the space, and increase the swing range of the air guide to ensure that the swing amplitude of the air guide meets the use requirements.

[0015] An electrical appliance using the air supply assembly includes a fan and the air supply assembly. The airflow generated by the fan is transported outward through the air supply assembly. The air supply assembly can effectively expand the air supply range and enhance the user experience. Appliances include heaters, bathroom heaters, and various other air supply devices.

[0016] The beneficial effects of the present invention are as follows: an end guide portion is provided at the end of the baffle, and the baffle can avoid the motor when swinging. The end guide portion can be used to effectively guide the airflow flowing out from the end of the air outlet to ensure that the airflow can be transported to the preset area. The end guide portion can also completely block the motor and the rotating shaft connected between the motor and the air guide member when the baffle blocks the air outlet. By increasing the length of the baffle, the distance between the end edge of the baffle and the edge of the panel is shortened, thereby improving the aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0024] Example 1:

[0025] This embodiment provides an air supply component.

[0026] like Figure 1The air supply assembly shown is composed of a panel 1 with an air duct 4, an air guide 2 arranged on the panel 1, and a motor 3 for driving the air guide 2 to rotate. The air guide 2 can be swingably installed at the air outlet of the air duct 4. The air guide 2 includes a baffle 6, which extends outward along its length direction to form an end guide portion 5. The motor 3 is arranged on the end side of the air guide 2 and can be blocked by the end guide portion 5. The swinging path of the baffle 6 avoids the motor 3 so that the airflow flowing out of the end of the air outlet is transported to a preset area through the end guide portion 5. An end guide portion 5 is provided at the end of the baffle 6, and the baffle 6 can avoid the motor 3 when swinging. The end guide portion 5 can be used to effectively guide the airflow flowing out from the end of the air outlet to ensure that the airflow can be transported to the preset area. When the baffle 6 blocks the air outlet, the end guide portion 5 can be used to completely block the motor 3 and the rotating shaft 7 connected between the motor 3 and the air guide member 2. By increasing the length of the baffle 6, the distance between the end edge of the baffle 6 and the edge of the panel 1 is shortened, thereby improving the aesthetics.

[0027] In this embodiment, the air guide 2 is rotatably mounted at the air outlet via a rotating shaft 7, so that the air guide 2 can swing about the rotating shaft 7 between a closed position, which blocks the air outlet and shields the motor 3, and an open position, which exposes the air outlet. The end guide 5 swings back and forth through the avoidance notch 9, so that the air guide 2 can freely swing between the open and closed positions at the air outlet. When the air guide member 2 is in the closed position, the baffle 6 blocks the air outlet and is smoothly connected to the surface of the panel 1. The end guide plate 10 blocks the avoidance gap 9 and blocks the motor 3 and the rotating shaft 7 to separate the air duct 4 from the outside space. When the air guide member 2 is in the open position, the baffle 6 swings and forms a channel for air flow between the edge of the air outlet. The end guide plate 10 swings synchronously with the baffle 6 through the avoidance gap 9. The airflow in the air duct 4 is turned after contacting the baffle 6, ensuring that the airflow is transported to the preset space under the guidance of the baffle 6.

[0028] In this embodiment, the extension length of the end guide portion can be adjusted as needed and meets the requirements of shielding and air guiding, and should be regarded as a specific implementation method of this embodiment. When the end guide portion is shorter, the end guide portion can at least completely shield the rotating shaft 7 and the drive shaft 15 when the air guide member is switched to the closed position; when the end guide portion is longer, the end guide portion 5 can completely shield the motor 3, the drive shaft 15 and the rotating shaft 7 when the air guide member is switched to the closed position. From the front perspective of the user observing from bottom to top, the vertical projection of the motor and the end guide portion 5 completely overlap, which not only ensures that the motor is effectively shielded, but also effectively guides the airflow direction at the end of the air outlet.

[0029] In this embodiment, the swing angle of the air guide 2 when switching between the closed position and the open position is A, A ≥ 90°. By setting the avoidance gap 9, a swing space is provided for the end guide 5 (such as Figure 3 When the air guide 2 is switched to the open position, it can freely swing and position within the angle set by parameter A, ensuring that the air flow can be stably delivered to the preset space.

[0030] In this embodiment, a protrusion 8 with a mounting cavity is provided on one side of the end wall of the air duct 4, and the motor 3 is inserted and installed in the mounting cavity. A clearance gap 9 is formed on the other side of the end wall of the air duct 4 for the end guide 5 to swing. A protrusion 8 is provided on one side of the end wall of the air duct 4, and a clearance gap 9 is provided on the other side. The motor 3 is installed in the mounting cavity in the protrusion 8. The baffle 6 and the rotating shaft 7 are eccentrically arranged. The end guide 5 can swing around the protrusion 8 with the rotating shaft 7 as the center, which can not only completely block the protrusion 8 and the rotating shaft 7 when the air guide 2 is switched to the closed position, but also effectively guide the airflow output from the end of the air duct 4 when the air guide 2 is switched to the open position, ensuring that the airflow can be transported toward the preset space.

[0031] In this embodiment, the width of the baffle 6 corresponds to the width of the air outlet, the length of the middle section of the baffle 6 corresponds to the length of the air outlet, the length of the end guide portion 5 at the end of the baffle 6 corresponds to the length of the protrusion 8 along the axis of the motor 3, and when the air guide member 2 is switched to the closed position, the baffle 6 completely blocks the air outlet and covers the protrusion 8 and the rotating shaft 7.

[0032] In this embodiment, the air guide 2 includes a guide plate 10 provided in the middle section of the baffle 6. The guide plate 10 near the end guide portion 5 is connected to the drive shaft 15 of the motor 3 via the rotating shaft 7, so that the swing path of the air guide 2 avoids the protrusion 8. The guide plate 10 is vertically provided on the middle section of the baffle 6. The guide plate 10 at the endmost end is connected to the drive shaft 15 of the motor 3 via the rotating shaft 7, and a space for accommodating the protrusion 8 is reserved between the guide plate 10 and the end edge of the baffle 6. After installation, the motor 3 provided in the protrusion 8 is connected to the rotating shaft 7 provided on the guide plate 10 via the driving shaft 15. When in use, the driving shaft 15 of the motor 3 drives the guide to rotate via the rotating shaft 7, and the guide plate 10 drives the baffle 6 to swing, so that the end guide portion 5 can avoid the protrusion 8 and achieve free swing.

[0033] In this embodiment, the guide plates 10 are multiple and are equidistantly spaced along the length of the baffle 6, ensuring that the airflow output from each area of the air duct 4 can be accurately delivered to the preset space under the guidance of the guide plates 10 and the baffle 6. In addition, in order to improve the deformation resistance of the air guide 2, the ends of the guide plates 10 facing away from the baffle 6 can be connected by a top plate 11 (such as Figure 4 As shown), the vertical projections of the top plate 11 and the raised portion 8 are staggered with each other, and the top plate 11 is used to strengthen the structural strength and guide the airflow, which should also be regarded as a specific implementation method of this embodiment.

[0034] In this embodiment, the protrusion 8 is formed integrally with the panel 1, and the outer end surface of the protrusion 8 facing away from the air duct 4 is provided with an assembly port 12 for disassembling the power supply unit 3 (eg, Figure 5 As shown, the raised portion 8 faces the inner end surface of the air duct 4 and is sealed to the inner wall of the air duct 4 to prevent air from leaking out of the air duct 4. The panel 1 and the raised portion 8 are integrally injection molded, which not only facilitates processing but also ensures a sealed connection between the raised portion 8 and the inner wall of the air duct 4. This prevents air leakage by eliminating gaps, ensuring that air can flow out effectively, and reduces kinetic energy loss of airflow by reducing wind resistance on the inner wall of the air duct 4, ensuring that the airflow can effectively maintain its flow rate.

[0035] In this embodiment, the motor 3 includes a cylindrical housing 13, an eccentrically arranged drive shaft 15, and a terminal box 14 arranged on the side of the housing 13 away from the drive shaft 15. The motor 3 deflects away from the avoidance gap 9 with its drive shaft 15 as the center, so that the height of the installation cavity is reduced and the swingable angle of the air guide 2 is increased. The terminal box 14 is arranged on the outer peripheral wall of the housing 13 away from the drive shaft 15. The inner contour of the installation cavity matches the contour of the motor 3, which plays a role in clamping and limiting the rotation of the motor 3, thereby improving the swing accuracy of the air guide 2. The motor 3 deflects toward the avoidance gap 9 and away from the avoidance gap 9, which can not only reserve space for the opening of the avoidance gap 9 and effectively increase the swing angle of the air guide 2, but also set the terminal box 14 on the top side of the housing 13 to reduce the overall height of the motor 3, thereby effectively reducing the space required for the installation of the air supply assembly. Specifically, the motor 3 has a center plane passing through the stator axis and the center line of the terminal box 14, and the angle between the center plane and the vertical plane is B (such as Figure 2 As shown in the figure, B = 57°. This ensures that the air guide 2 has a large swing angle, effectively expanding the air supply range, and effectively limits the size of the installation cavity, improving space utilization efficiency. In addition, parameter B can also be 50°, 55°, 60°, 65°, etc., as long as the requirement of 50°≤B≤65° is met.
