Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to air outlet devices and household appliances. Background Technology

[0002] Heaters, electric heaters, and other air-discharging devices are common household appliances that typically use convection to heat the air and raise the indoor temperature for users. However, the air-discharging devices in these technologies have a single airflow direction, limited to the front or top, resulting in a limited airflow range and making it difficult to meet the needs of whole-house heating. Summary of the Invention

[0003] In view of this, the present invention provides an air outlet device and a household appliance to solve the problem of small air delivery range in related technologies.

[0004] In a first aspect, the present invention provides an air outlet device, comprising: The outer casing is equipped with a first air outlet and a second air outlet; The wind turbine assembly is housed inside the casing and has a wind turbine inlet and a wind turbine outlet. A diverter plate is rotatably disposed at the air outlet of the impeller, and can adjust the airflow from the air outlet of the impeller to the first air outlet and / or the second air outlet.

[0005] Beneficial effects: The outer casing has a first air outlet and a second air outlet. The airflow from the impeller outlet can flow to the first and second air outlets respectively, achieving simultaneous airflow in two directions with almost no loss of air volume. This expands the air supply range, improves the air supply effect, and enhances the comfort of the indoor environment. By incorporating a diverter plate, which is rotatably mounted at the impeller outlet, the airflow from the impeller outlet to the first and / or second air outlets can be adjusted to meet different user needs.

[0006] In one optional embodiment, a first air duct and a second air duct are formed between the outer casing and the impeller assembly. The first air duct connects the impeller outlet and the first air outlet, and the second air duct connects the impeller outlet and the second air outlet. The diverter plate is rotatably disposed in the second air duct. When the diverter plate is in a horizontal position, the second air duct is blocked, and all the airflow from the impeller outlet flows to the first air outlet. When the diverter plate is at a predetermined angle to the horizontal plane, an air passage gap is formed between the diverter plate and the side wall of the second air duct.

[0007] Beneficial effects: When the diverter plate is in a horizontal position, the second air duct is blocked, and all the airflow from the impeller outlet flows to the first air outlet, at which point the airflow at the first air outlet reaches its maximum. When the diverter plate is at a predetermined angle to the horizontal plane, an air gap is formed between the diverter plate and the side wall of the second air duct. At this time, part of the airflow from the impeller outlet flows to the first air outlet and is blown out from the first air outlet, while part flows through the air gap to the second air outlet and is blown out from the second air outlet, achieving the effect of airflow from two directions simultaneously and realizing full-area air supply.

[0008] In one optional embodiment, a first air duct and a second air duct are formed between the housing and the impeller assembly. The first air duct connects the impeller outlet and the first air outlet, and the second air duct connects the impeller outlet and the second air outlet. The diverter plate is rotatably disposed in the second air duct, and the diverter plate is provided with openings.

[0009] In one alternative implementation, the housing includes: Shell body; The first air outlet grille is disposed on the side of the shell body near the air outlet of the impeller, and the grille gap of the first air outlet grille constitutes the first air outlet. The diverter plate is rotatably mounted on the first air outlet grille.

[0010] Beneficial effects: By rotatably mounting the diverter plate on the first air outlet grille, the diverter plate can be pre-assembled onto the first air outlet grille during installation, and then the first air outlet grille can be connected to the housing body, which facilitates disassembly and assembly.

[0011] In one alternative embodiment, the first air outlet is disposed on the side of the housing, the second air outlet is disposed on the top of the housing, and the diverter is disposed at the end of the first air outlet grille near the second air outlet.

[0012] Beneficial effects: It enables simultaneous airflow from both the top and sides, expanding the air supply range and enhancing air circulation. When the air outlet delivers hot air, the hot air exiting from the sides is directed forward, heating the bottom and slowly sending heat upwards through natural convection; the hot air exiting from the top enhances the upward heat transfer rate, thereby increasing the overall heat output and expanding the airflow dissipation range. This achieves greater airflow diffusion, meeting the air supply needs of the entire room and improving indoor comfort. By placing the diverter plate at the end of the first air outlet grille near the second air outlet, it facilitates the diversion of some of the air from the impeller outlet to the second air outlet at the top.

[0013] In one alternative embodiment, the air outlet device further includes a drive structure connected to the splitter plate and capable of driving the splitter plate to rotate.

[0014] Beneficial effects: By setting up a drive structure, the splitter plate can be rotated. The splitter plate can be rotated to the required position by controlling the operation of the drive structure, reducing manual operation.

[0015] In one optional embodiment, a motor mounting bracket is provided at the first end of the first air outlet grille, the drive structure includes a drive motor, the drive motor is fixed to the motor mounting bracket, and the output shaft of the drive motor is connected to the first end of the splitter plate.

[0016] Beneficial effects: By setting a motor mounting bracket at the first end of the first air outlet grille, it is convenient to install the drive motor. In addition, during assembly, the drive motor, the first air outlet grille and the splitter plate can be pre-assembled into a whole, and then the first air outlet grille can be connected to the shell body for easy disassembly and assembly.

[0017] In one alternative embodiment, the second end of the diverter plate is rotatably engaged with the second end of the first air outlet grille.

[0018] Beneficial effect: The second end of the diffuser plate rotates and engages with the second end of the first air outlet grille, which can support and limit the second end of the diffuser plate, ensuring that the diffuser plate can rotate smoothly.

[0019] In one alternative embodiment, the diverter plate is disposed on the side of the first air outlet grille near the impeller assembly, and is located at the end of the first air outlet grille near the second air outlet.

[0020] Beneficial effect: By setting the diverter plate at one end of the first air outlet grille near the second air outlet, it is convenient to divert part of the gas coming out of the impeller outlet to the second air outlet.

[0021] In one alternative embodiment, the wind turbine assembly includes a wind turbine and a volute. The cochlear tongue includes: The volute tongue main body section is located on the outer periphery of the wind turbine, and has an air inlet end and an air outlet end along the airflow direction; The volute tongue guide section extends from the air outlet end of the volute tongue main body section toward the direction close to the second air outlet. The volute tongue guide section and the outer shell enclose the second air duct. When the diverter plate is in a horizontal position, the diverter plate abuts against the volute tongue guide section.

[0022] Beneficial effects: By adopting the design of the volute tongue guide section, the volute tongue can also serve as a guide, directing the airflow of the upward branch towards the second air outlet, achieving the effect of multiple uses and simplifying the structure.

[0023] In one optional embodiment, the wind turbine assembly further includes: The volute and the volute tongue are located on the outer periphery of the wind turbine and are arranged at intervals along the circumference of the wind turbine. The wind turbine inlet and the wind turbine outlet are formed on both sides of the volute tongue and the volute shell respectively along the airflow direction. The volute includes: The volute main body section is located below the wind turbine; The volute guide section is located at one end of the volute main body section near the wind turbine outlet, and extends towards the first outlet. The volute guide section, the diverter plate, and the outer shell enclose a first air duct, which connects the ventilation wheel outlet and the first air outlet.

[0024] Beneficial effects: By employing a volute guide section design, the volute can also function as a wind guide, directing the airflow from the forward branch towards the first air outlet. This design of the volute and volute tongue ensures sufficient airflow at both the first and second air outlets, achieving both upward and forward convection, thus increasing the airflow range. When the air outlet delivers hot air, it ensures simultaneous upward and forward convection heating, expanding the heating range and meeting the user's need for simultaneous foot and body heating. Furthermore, it achieves multi-functionality and simplifies the structure.

[0025] Secondly, the present invention also provides a household appliance, including the aforementioned air outlet device.

[0026] In one alternative implementation, the household appliance is a heater or a fan heater.

[0027] In one optional embodiment, the household appliance further includes: The heating element has an air inlet on its outer casing and is disposed between the air inlet and the air inlet of the impeller.

[0028] Beneficial effect: By setting up a heating element, the air flowing into the air inlet of the impeller can be heated, thereby achieving the effect of producing warm air.

[0029] In one alternative implementation, the projections of the heating element and the impeller along the height direction of the housing at least partially overlap.

[0030] Beneficial effects: The heating element is arranged on the air inlet side of the impeller, and the projection of the heating element along the height direction of the outer shell overlaps at least partially with the projection of the impeller along the height direction of the outer shell. This effectively ensures the compactness of the air outlet device in the lateral direction, that is, the width will not be too large, improving the compactness of the overall structure, which is more conducive to the miniaturization design of the whole machine and reducing the floor space.

[0037] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Heaters, electric heaters, and other air-discharging devices are common household appliances that typically use convection to heat the air and raise the indoor temperature for users. However, existing air-discharging devices have a single airflow direction, limited to the front or top, resulting in a limited airflow range that is difficult to meet the needs of whole-house heating.

[0039] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, in one aspect, an air outlet device is provided, including a housing 10, a fan assembly 20, and a diverter plate 15.

[0041] The outer casing 10 is provided with a first air outlet 101 and a second air outlet 102; the impeller assembly 20 is disposed inside the outer casing 10, and the impeller assembly 20 has an impeller inlet 201 and an impeller outlet 202; the diverter plate 15 is rotatably disposed at the impeller outlet 202, and can adjust the airflow from the impeller outlet 202 to the first air outlet 101 and / or the second air outlet 102.

[0042] In this embodiment, the outer casing 10 is provided with a first air outlet 101 and a second air outlet 102. The airflow from the impeller air outlet 202 can flow to the first air outlet 101 and the second air outlet 102 respectively, achieving the effect of simultaneous airflow in two directions with almost no loss of air volume. This expands the air supply range, improves the air supply effect, and enhances the comfort of the indoor environment. By setting a diverter plate 15, which is rotatably disposed at the impeller air outlet 202, the airflow from the impeller air outlet 202 to the first air outlet 101 and / or the second air outlet 102 can be adjusted to meet different user needs.

[0043] Specifically, the manifold 15 can be manually driven to rotate, or it can be driven by a drive structure. When the manifold 15 is manually driven to rotate, it passes through the housing 10 and can be rotated outside the housing 10.

[0044] In one embodiment, a first air duct and a second air duct are formed between the outer casing 10 and the impeller assembly 20. The first air duct connects the ventilation wheel outlet 202 and the first air outlet 101, and the second air duct connects the ventilation wheel outlet 202 and the second air outlet 102. A diverter plate 15 is rotatably disposed in the second air duct. When the diverter plate 15 is in a horizontal position, the second air duct is blocked, and all the airflow from the impeller outlet 202 flows to the first air outlet 101. When the diverter plate 15 is at a predetermined angle to the horizontal plane, an air passage gap is formed between the diverter plate 15 and the side wall of the second air duct.

[0045] In this embodiment, when the diverter plate 15 is in a horizontal position, the second air duct is blocked, and all the airflow from the impeller outlet 202 flows to the first outlet 101. At this time, the airflow of the first outlet 101 reaches its maximum. When the diverter plate 15 is at a predetermined angle to the horizontal plane, an air gap is formed between the diverter plate 15 and the side wall of the second air duct. At this time, part of the airflow from the impeller outlet 202 flows to the first outlet 101 and is blown out from the first outlet 101, and part of the airflow flows through the air gap to the second outlet 102 and is blown out from the second outlet 102, thus achieving the effect of airflow from two directions at the same time and realizing full-area air supply.

[0046] Specifically in one embodiment, such as Figure 2As shown, when the angle between the diverter plate 15 and the horizontal plane is 45°, an air gap is formed between the diverter plate 15 and the side wall of the second air duct. At this time, part of the airflow is blown out from the first air outlet 101 and part of the airflow is blown out from the second air outlet 102.

[0047] Specifically in one embodiment, such as Figure 3 As shown, when the diverter plate 15 is perpendicular to the horizontal plane, the second air duct is at its maximum opening. Part of the airflow is blown out from the first air outlet 101, and part of the airflow is blown out from the second air outlet 102. The airflow blown out from the second air outlet 102 reaches its maximum.

[0048] In a preferred embodiment, the diverter plate 15 does not have air passage holes. In other alternative embodiments, a first air duct and a second air duct are formed between the housing 10 and the impeller assembly 20. The first air duct connects the ventilation wheel outlet 202 and the first air outlet 101, and the second air duct connects the ventilation wheel outlet 202 and the second air outlet 102. The diverter plate 15 is rotatably disposed in the second air duct, and the diverter plate 15 has openings.

[0049] When the diverter plate 15 is in a horizontal position, some airflow passes through the opening and flows to the second air outlet 102; when the diverter plate 15 is tilted, some airflow passes through the opening and flows to the second air outlet 102, and some airflow passes through the air gap between the diverter plate 15 and the side wall of the second air duct and flows to the second air outlet 102. The diverter plate 15 can also regulate the airflow from the impeller outlet 202 to the first air outlet 101 and the second air outlet 102.

[0050] Specifically, the first air outlet 101 and the second air outlet 102 can be located on adjacent side walls of the outer casing 10, or one can be located on a side wall of the outer casing 10 and the other on a top wall of the outer casing 10, or the first air outlet 101 and the second air outlet 102 can be located on opposite side walls of the outer casing 10. Preferably, one of the first air outlet 101 and the second air outlet 102 is located on the front side wall of the outer casing 10, and the other is located on the top wall of the outer casing 10.

[0051] In one embodiment, the outer casing 10 includes a casing body and a first air outlet grille 121. The first air outlet grille 121 is disposed on the side of the casing body near the impeller air outlet 202, and the grille gap of the first air outlet grille 121 forms a first air outlet 101; the diverter plate 15 is rotatably disposed on the first air outlet grille 121.

[0052] In this embodiment, by rotatably mounting the diverter plate 15 onto the first air outlet grille 121, the diverter plate 15 is pre-assembled onto the first air outlet grille 121 during installation, and then the first air outlet grille 121 is connected to the housing body, which facilitates disassembly and assembly.

[0053] Specifically, the first air outlet grille 121 is detachably mounted on the housing body for easy cleaning and maintenance. An installation port is provided at the bottom of the front side wall of the housing body, and the first air outlet grille 121 is detachably mounted at the installation port of the housing body. Optionally, the first air outlet grille 121 is installed and fixed to the housing body by means of screws, clips, interference fits, etc.

[0054] Furthermore, the shell body includes a bottom plate 14, a front plate 12, a rear plate 13, and left and right side plates. A first air outlet grille 121 is installed at the bottom of the front plate 12, and a second air outlet grille 11 is installed at the top of the shell body. The second air outlet 102 is formed by the grille gaps of the second air outlet grille 11. An air inlet 130 is provided on the rear plate 13, which communicates with the external space and is used to introduce external air into the shell 10 for heating, and then deliver it to the impeller assembly 20.

[0055] In one embodiment, a first air outlet 101 is disposed on the side of the housing 10, a second air outlet 102 is disposed on the top of the housing 10, and a diverter 15 is disposed at one end of the first air outlet grille 121 near the second air outlet 102.

[0056] In this embodiment, simultaneous airflow from both the top and sides is achieved, expanding the air supply range and enhancing airflow. When the air outlet device delivers hot air, the hot air exiting from the side is directed forward, heating the bottom and slowly sending heat upward through natural convection; the hot air exiting from the top enhances the upward heat transfer rate, thereby increasing the overall heat output and expanding the airflow dissipation range. This achieves greater airflow diffusion, meeting the air supply needs of the entire house and improving the comfort of the indoor environment. By placing the diverter plate 15 at one end of the first air outlet grille 121 near the second air outlet 102, it is convenient to divert some of the gas exiting from the impeller outlet 202 to the second air outlet 102 at the top.

[0057] Specifically, the first air outlet 101 is located at the bottom side of the housing 10, the impeller assembly 20 is located at the bottom of the housing 10, and the impeller outlet 202 is located on the side close to the first air outlet 101. More specifically, the first air outlet 101 is located at the bottom front side of the housing 10, and the second air outlet 102 is located at the top of the housing 10, so that the air outlet device can achieve the effect of simultaneously venting air from both the top and front sides.

[0058] In one embodiment, the air outlet device further includes a drive structure connected to the diverter plate 15 and capable of driving the diverter plate 15 to rotate.

[0059] In this embodiment, by setting a driving structure, the splitter plate 15 can be rotated. The splitter plate 15 can be rotated to the required position by controlling the operation of the driving structure, reducing manual operation.

[0060] In some alternative embodiments, the drive structure may not be provided, and the position of the splitter plate 15 may be adjusted by manually rotating the splitter plate 15.

[0061] In one embodiment, the first end of the first air outlet grille 121 is provided with a motor fixing bracket 17, and the drive structure includes a drive motor 16, which is fixed to the motor fixing bracket 17, and the output shaft of the drive motor 16 is connected to the first end of the diverter plate 15.

[0062] In this embodiment, by providing a motor fixing bracket 17 at the first end of the first air outlet grille 121, it is convenient to install the drive motor 16. In addition, during assembly, the drive motor 16, the first air outlet grille 121 and the diverter plate 15 can be pre-assembled into a whole, and then the first air outlet grille 121 can be connected to the shell body for easy disassembly and assembly.

[0063] Specifically, the drive motor 16 is fixed to the motor mounting bracket 17 by screws.

[0064] In one specific embodiment, the output shaft of the drive motor 16 is non-circular, and the first end of the splitter plate 15 is provided with a first shaft hole 1501. The shape of the first shaft hole 1501 is adapted to the output shaft of the drive motor 16, and the output shaft of the drive motor 16 is inserted into the first shaft hole 1501.

[0065] More specifically, the output shaft of the drive motor 16 is D-shaped.

[0066] In one embodiment, the second end of the diverter 15 is rotatably engaged with the second end of the first air outlet grille 121.

[0067] In this embodiment, the second end of the diverter plate 15 is rotatably engaged with the second end of the first air outlet grille 121, which can support and limit the second end of the diverter plate 15, ensuring that the diverter plate 15 can rotate smoothly.

[0068] In one specific embodiment, the second end of the diverter plate 15 is provided with a rotating shaft 1502, and the second end of the first air outlet grille 121 is provided with a second shaft hole 1211, and the rotating shaft 1502 is rotatably disposed in the second shaft hole 1211.

[0069] In one embodiment, the diverter plate 15 is disposed on the side of the first air outlet grille 121 near the wind turbine assembly 20, and is located at the end of the first air outlet grille 121 near the second air outlet 102.

[0070] In this embodiment, by setting the diverter plate 15 at one end of the first air outlet grille 121 near the second air outlet 102, it is convenient to divert part of the gas coming out of the impeller outlet 202 to the second air outlet 102.

[0071] In one specific embodiment, the diverter 15 is connected to the top of the first air outlet grille 121.

[0072] In one embodiment, the impeller assembly 20 includes an impeller 21 and a volute 22. The volute 22 includes a volute body section 221 and a volute guide section 222. The volute body section 221 is located on the outer periphery of the impeller 21 and has an air inlet end and an air outlet end along the airflow direction. The volute guide section 222 extends from the air outlet end of the volute body section 221 toward the direction close to the second air outlet 102. The volute guide section 222 and the outer casing 10 enclose each other to form a second air duct. When the diverter plate 15 is in a horizontal position, the diverter plate 15 abuts against the volute guide section 222.

[0073] In this embodiment, the volute tongue 22 is designed with a volute tongue guide section 222, which enables the volute tongue 22 to also serve as a guide, guiding the airflow of the upward branch to flow towards the second air outlet 102, thus achieving the effect of multiple uses and simplifying the structure.

[0074] Furthermore, combined Figures 1 to 3 as well as Figure 8 As shown, the volute tongue main body section 221 is located above the impeller 21, and the volute tongue guide section 222 is formed by extending vertically upward from the air outlet end of the volute tongue main body section 221. In other modified embodiments, the volute tongue guide section 222 is formed by extending obliquely upward from the air outlet end of the volute tongue main body section 221. The volute tongue guide section 222 is inclined towards the first air outlet 101 or it can be inclined away from the first air outlet 101. The extension direction of the volute tongue guide section 222 is determined according to the relative position of the second air outlet 102 and the impeller air outlet 202.

[0075] In one embodiment, the shortest distance between the air outlet end of the volute tongue main body segment 221 and the highest edge of the first air outlet 101 is h1; when the diverter plate 15 is in a horizontal position, the shortest distance between the lowest point of the diverter plate 15 and the highest edge of the first air outlet 101 is h2, where h1≤h2.

[0076] In the above embodiment, the junction of the volute tongue main body section 221 and the volute tongue guide section 222 is the lowest point of the volute tongue 22. By setting the shortest distance h2 between the lowest point of the diverter plate 15 and the highest edge of the first air outlet 101 within the above-mentioned size range, it can be ensured that the diverter plate 15 is located above the lowest point of the volute tongue 22, avoiding the problem of the diverter plate 15 being lower than the lowest point of the volute tongue 22, resulting in loud whistling and unsatisfactory noise reduction. At the same time, it can also avoid the problem of the diverter plate 15 being too high, thus failing to achieve a good diversion effect. The air outlet device also includes a guide plate 40 disposed between the volute tongue 22 and the second air outlet 102. The volute tongue guide section 222, the outer shell 10, and the guide plate 40 enclose a first air duct, which connects the ventilation wheel air outlet 202 and the second air outlet 102.

[0077] In the above embodiment, the design of the air guide plate 40 can guide the airflow towards the second air outlet 102. Specifically, the volute tongue main body section 221 and the volute tongue guide section 222 are integrally formed. The volute tongue guide section 222 has a flat wall surface and can guide the airflow drawn from the impeller outlet 202 towards the direction close to the second air outlet 102. The air guide plate 40 has an air guide wall, and the outer wall of the air guide wall is connected to the flat wall surface of the volute tongue guide section 222. The two work together to guide the airflow to the second air outlet 102.

[0078] In one embodiment, the impeller assembly 20 further includes a volute 23. The volute tongue 22 and the volute 23 are located on the outer periphery of the impeller 21 and are arranged at intervals along the circumference of the impeller 21. An impeller inlet 201 and an impeller outlet 202 are formed on both sides of the volute tongue 22 and the volute 23 respectively along the airflow direction. The volute 23 includes a volute body section 231, which is located below the impeller 21. The volute 23 also includes a volute guide section 232, which is disposed at one end of the volute body section 231 near the impeller outlet 202. The volute guide section 232 extends toward the first outlet 101. The volute guide section 232, together with the diverter plate 15 and the outer shell 10, forms a first air duct. The first air duct connects the impeller outlet 202 and the first outlet 101.

[0079] In this embodiment, the volute 23, through the design of the volute guide section 232, can also function as a wind guide, directing the airflow of the forward branch towards the first air outlet 101. By adopting the above design, the volute 23 and volute tongue 22 can ensure the airflow of the first air outlet 101 and the second air outlet 102, simultaneously achieving upward and forward convection airflow, thus increasing the airflow range. When the air delivered by the air outlet device is hot air, it can ensure simultaneous upward and forward convection heating, increasing the heating range and meeting the user's need for simultaneous heating of the feet and body. Furthermore, it achieves multi-functionality and simplifies the structure.

[0080] Furthermore, the volute main body section 231 and the volute guide section 232 are integrally formed. The volute main body section 231 is arc-shaped, and the side wall of the volute guide section 232 facing the diverter plate 15 is a flat guide wall. The guide wall is used to guide the airflow drawn from the impeller outlet 202 to the first outlet 101. The side wall of the volute guide section 232 facing the first outlet grille 121 fits against the first outlet grille 121 located below the lowest edge of the first outlet 101, avoiding gaps between the volute 23 and the first outlet grille 121 that would cause air leakage. Through the above design, the volute guide section 232 can cooperate with the diverter plate 15 to form a second air duct, reducing airflow loss.

[0081] Of course, in some embodiments, the wall surface of the volute guide section 232 facing the first air outlet grille 121 is attached to the bottom of the first air outlet grille 121, and the projection of the volute guide section 232 along the airflow direction at least partially overlaps with the projection of the first air outlet 101 along the airflow direction, so as to block and obstruct part of the first air outlet 101, reduce the area of ​​the first air outlet 101, and thus increase the air outlet speed.

[0082] For example, such as Figures 1 to 3 As shown, the end wall of the volute guide section 232 abuts against the two lowest grille ribs, blocking the gap of the lowest grille, thereby reducing the area of ​​the first air outlet 101.

[0083] Furthermore, in this embodiment, the volute 23 is fixed to the base plate 14 of the outer shell 10.

[0084] According to an embodiment of the present invention, in another aspect, a household appliance is also provided, including the air outlet device provided in the above embodiments.

[0085] In this embodiment, the household appliance is a heater or a fan heater. Preferably, the household appliance is a baseboard heater.

[0086] The household appliance is a heater, which includes the air outlet device of any of the above embodiments. This device enables simultaneous airflow from both the top and sides. The hot airflow exiting from the sides heats the bottom through initial airflow and then slowly rises via natural convection. The hot airflow exiting from the top enhances the upward heat transfer rate, thereby increasing the overall heat output and expanding the heater's heat dissipation range. This allows for greater heat diffusion, meeting the heating needs of the entire house and improving indoor comfort. Furthermore, by providing a diverter plate 15, which is rotatably positioned at the fan outlet 202, the airflow from the fan outlet 202 to the first outlet 101 and / or the second outlet 102 can be adjusted to meet different user needs.

[0087] In one embodiment, the household appliance further includes a heating element 50, and the housing 10 is provided with an air inlet 130. The heating element 50 is disposed between the air inlet 130 and the impeller air inlet 201.

[0088] By setting the heating element 50, the air flowing into the air inlet 201 of the impeller can be heated, thereby achieving the effect of producing warm air.

[0089] Furthermore, the projections of the heating element 50 and the impeller 21 along the height direction of the housing 10 at least partially overlap.

[0090] In this embodiment, the heating element 50 is arranged on the air inlet side of the impeller 21, and the projection of the heating element 50 along the height direction of the outer casing 10 at least partially overlaps with the projection of the impeller 21 along the height direction of the outer casing 10. This effectively ensures the compactness of the air outlet device in the lateral direction, that is, the width will not be too large, improving the compactness of the overall structure, which is more conducive to the miniaturization design of the whole machine and reducing the floor space.

[0091] Furthermore, the heating element 50 is located between the air inlet 130 and the impeller 21. The air inlet 130 of the outer casing 10 is provided with an upper air inlet cover 60 and a lower air inlet cover 70. The upper air inlet cover 60 is located above the heating element 50, and the lower air inlet cover 70 is located below the heating element 50. The upper air inlet cover 60 and the lower air inlet cover 70 enclose and form an air inlet channel that connects the air inlet 130 and the impeller air inlet 201. The heating element 50 is located inside the air inlet channel.

[0092] The following description, with reference to the accompanying drawings, uses a heater as an example to illustrate the specific structure and working principle of the household appliance provided in this embodiment.

[0093] The specific structure is as follows: Combination Figures 1 to 3 As shown, the heater provided in this embodiment includes a shell 10 (including a bottom plate 14, a front plate 12, a rear plate 13, left and right side plates, a first air outlet grille 121, and a second air outlet grille 11), an upper air inlet cover 60, a heating element 50, a lower air inlet cover 70, a fan assembly 20 (including a fan 21, a volute tongue 22, and a volute shell 23), a diverter plate 15, a drive motor 16, and a guide plate 40. The rear plate 13 is provided with several small air inlets to form an air inlet 130. The heating element 50 is located on the air inlet side of the impeller 21. The upper air inlet cover 60 and the lower air inlet cover 70 are located on the upper and lower sides of the heating element 50, respectively, covering the heating element 50 to ensure that the air drawn in by the impeller 21 can effectively remove the heat of the heating element 50. The volute 23 is located on the lower side of the impeller 21 and is fixed on the base plate 14. The volute 23 includes a volute main body section 231 and a volute guide section 232 formed by extending the volute main body section 231. The volute guide section 232, together with the outer shell 10 and the diverter plate 15, forms a second air duct. The volute tongue 22 is located on the upper side of the impeller 21. The volute tongue 22 includes a volute tongue main body section 221 and a volute tongue guide section 222 provided on the volute tongue main body section 221. The volute tongue guide section 222, together with the outer shell 10 and the air guide plate 40, forms a first air duct.

[0094] The working principle is as follows: like Figure 2 and Figure 3As shown, when the heater is working, the fan wheel 21 rotates, and cold air enters the interior of the outer casing 10 through the air inlet 130 of the rear panel 13. After being heated by the heating element 50, it flows out from the fan wheel outlet 202. The airflow is then divided into two streams, one forward and one upward, by the flow divider 15, and flows out through the first air outlet grille 121 and the second air outlet grille 11. The hot airflow from the first air outlet grille 121 heats the bottom through initial airflow and slowly sends heat upwards via natural convection. The hot airflow from the second air outlet grille 11 enhances the upward heat transfer rate, thereby increasing the overall heat output and expanding the heat dissipation range of the baseboard. Figure 1 As shown, when the diverter plate 15 is in a horizontal position, the upward channel is closed, and the airflow can only come out from below, achieving carpet-like uniform heating.

[0095] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by this application.
