Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to heating components and household appliances. Background Technology

[0002] In related technologies, the heating components of skirting board products include a rapid-heating evaporator assembly, an upper air inlet plate, a volute, a lower air inlet plate, a volute housing, a fan assembly, a left side plate, and a right side plate. These components are all assembled between the left and right side plates, and are positioned and connected via them. During assembly, these six components are typically positioned one by one onto the left side plate, and then the right side plate is fixed to them. Due to dimensional errors in the parts, the left and right side plates are prone to twisting during the fixing process. Utility Model Content

[0003] In view of this, the present invention provides a heating component and a household appliance to solve the problem that the left and right side plates of the heating components in the related technology are easily twisted due to part size errors.

[0004] In a first aspect, this utility model provides a heating assembly, comprising:

[0005] The upper frame assembly includes a first upper side plate, a second upper side plate, an upper air inlet plate, a volute, and an evaporator assembly. The upper air inlet plate, the volute, and the evaporator assembly have the same assembly length and are all assembled between the first upper side plate and the second upper side plate.

[0006] The lower frame assembly includes a first lower side plate, a second lower side plate, a lower air inlet plate, a volute, and a wind turbine assembly. The lower air inlet plate, the volute, and the wind turbine assembly have the same assembly length and are all assembled between the first lower side plate and the second lower side plate. The lower frame assembly is connected to the upper frame assembly.

[0007] Beneficial effects: The first upper side plate and the first lower side plate are separate structures, as are the second upper side plate and the second lower side plate. The upper air inlet plate, volute, and evaporator assembly have the same assembly length and are all assembled between the first and second upper side plates to form the upper frame assembly. The lower air inlet plate, volute, and impeller assembly have the same assembly length and are all assembled between the first and second lower side plates to form the lower frame assembly. Individually, the first upper side plate, the first lower side plate, the second upper side plate, and the second lower side plate are less prone to twisting. During assembly, the upper frame assembly and the lower frame assembly are assembled separately. Because the upper air inlet plate, volute, and evaporator assembly have the same assembly length, the assembly difficulty of the upper frame assembly is relatively low. Similarly, because the lower air inlet plate, volute, and impeller assembly have the same assembly length, the assembly difficulty of the lower frame assembly is relatively low. Therefore, the overall assembly difficulty can be reduced.

[0008] Compared with related technologies, dividing the left side plate into a first upper side plate and a first lower side plate, and dividing the right side plate into a second upper side plate and a second lower side plate, can avoid the twisting and deformation of the left and right side plates due to part size errors.

[0009] In one optional embodiment, the upper air intake plate and the volute assembly form a first assembly unit, which is assembled between the first upper side plate and the second upper side plate.

[0010] Beneficial effects: Pre-assembling the upper air intake plate and the volute into the first assembly unit, and assembling the first assembly unit as a whole with the evaporator assembly between the first upper side plate and the second upper side plate, makes assembly easier and can effectively reduce the problem of twisting and deformation caused by the error of each component.

[0011] In one alternative embodiment, the evaporator assembly includes an evaporator, a first support structure, and a second support structure. A first end of the evaporator is axially movable relative to the first support structure, and a second end of the evaporator is fixed to the second support structure. The first support structure is connected to a first upper side plate, and the second support structure is connected to a second upper side plate.

[0012] Beneficial effects: Since the first end of the evaporator can move axially relative to the first support structure, and the second end of the evaporator is fixed to the second support structure, the first support structure is connected to the first upper side plate, and the second support structure is connected to the second upper side plate, the assembly difficulty caused by dimensional tolerances can be reduced, and the second upper side plate can be tightly fitted with the upper air inlet plate.

[0013] In one optional embodiment, the first support structure includes a first support and a first support cover, the second support structure includes a second support and a second support cover, a first end of the evaporator is disposed between the first support and the first support cover, and a second end of the evaporator is disposed between the second support and the second support cover.

[0014] Beneficial effects: The first support structure includes a first support and a first support cover, and the second support structure includes a second support and a second support cover, which facilitates limiting the two ends of the evaporator.

[0015] In one optional embodiment, the second end of the evaporator is provided with a positioning post, and the second bracket is provided with a positioning groove, wherein the positioning post is embedded in the positioning groove.

[0016] Beneficial effects: The second end of the evaporator is equipped with a positioning post, and the second bracket is equipped with a positioning groove. The positioning post is embedded in the positioning groove, which facilitates the limiting and fixing of the second end of the evaporator.

[0017] In one optional embodiment, the first lower side plate is provided with a mounting through hole, and a bearing housing assembly is provided in the mounting through hole. The end of the wind turbine assembly away from the motor is located in the bearing housing assembly.

[0018] Beneficial effects: By providing a mounting through hole in the first lower side plate, and a bearing housing assembly inside the mounting through hole, the end of the impeller assembly away from the motor is located in the bearing housing assembly. Therefore, the impeller assembly can move axially relative to the mounting through hole, ensuring that the assembly of the lower frame assembly is not affected by the dimensional tolerance of the impeller assembly.

[0019] In one optional embodiment, the lower air intake plate and the volute are assembled to form a second assembly unit, which is assembled between the first lower side plate and the second lower side plate.

[0020] Beneficial effects: Pre-assembling the lower air intake plate and the volute into a second assembly unit, which is then assembled as a whole with the impeller assembly between the first and second lower side plates, makes assembly easier and reduces assembly difficulty. It can also effectively reduce the problem of torsion and deformation caused by errors in various components.

[0021] In one optional embodiment, the connection position between the first upper side plate and the first lower side plate is adjustable;

[0022] The connection position between the second upper side plate and the second lower side plate is adjustable.

[0023] Beneficial effects: The connection position of the first upper side plate and the first lower side plate is adjustable, which can prevent twisting and deformation when the first upper side plate and the first lower side plate are connected due to dimensional errors. The connection position of the second upper side plate and the second lower side plate is also adjustable, which can prevent twisting and deformation when the second upper side plate and the second lower side plate are connected due to dimensional errors.

[0024] In one optional embodiment, one of the first upper side plate and the first lower side plate is provided with a circular hole, and the other of the first upper side plate and the first lower side plate is provided with an elongated hole. Fasteners pass through the circular hole and the elongated hole to connect the first upper side plate and the first lower side plate.

[0025] One of the second upper side plate and the second lower side plate is provided with a round hole, and the other of the second upper side plate and the second lower side plate is provided with an elongated hole. Fasteners pass through the round hole and the elongated hole to connect the second upper side plate and the second lower side plate.

[0026] Beneficial effects: By providing a circular hole in one of the first upper side plate and a long oval hole in the other, and allowing fasteners to pass through both holes to connect the first upper and lower side plates, twisting deformation due to dimensional errors during connection can be avoided. Similarly, by providing a circular hole in one of the second upper side plate and a long oval hole in the other, and allowing fasteners to pass through both holes to connect the second upper and lower side plates, twisting deformation due to dimensional errors during connection can also be avoided.

[0027] Secondly, this utility model also provides a household appliance, including:

[0028] The heating component mentioned above.

[0029] Beneficial effects: In this household appliance, the first upper side panel and the first lower side panel are separate structures, as are the second upper side panel and the second lower side panel. The upper air inlet plate, volute, and evaporator assembly have the same assembly length and are all assembled between the first and second upper side panels to form the upper frame assembly. Similarly, the lower air inlet plate, volute, and impeller assembly have the same assembly length and are all assembled between the first and second lower side panels to form the lower frame assembly. Individually, the first upper side panel, the first lower side panel, the second upper side panel, and the second lower side panel are less prone to twisting. During assembly, the upper frame assembly and the lower frame assembly are assembled separately. Because the upper air inlet plate, volute, and evaporator assembly have the same assembly length, the assembly difficulty of the upper frame assembly is relatively low. Similarly, because the lower air inlet plate, volute, and impeller assembly have the same assembly length, the assembly difficulty of the lower frame assembly is relatively low. Therefore, the overall assembly difficulty can be reduced. Attached Figure Description

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0053] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0056] The heating components in the skirting board product include a fast-heating evaporator assembly, an upper air inlet plate, a volute, a lower air inlet plate, a volute housing, a fan assembly, a left side plate 1a, and a right side plate 2a. These components are all assembled between the left side plate 1a and the right side plate 2a, and are positioned and connected using the left side plate 1a and the right side plate 2a. The specific assembly process is as follows: First, each of the six components—the fast-heating evaporator assembly, upper air inlet plate, volute, lower air inlet plate, volute housing, and fan assembly—is positioned onto the left side plate 1a and secured with screws. Then, the right side plate 2a is fitted over these secured components. Because the fast-heating evaporator assembly, upper air inlet plate, and other components exceed half a meter in length, when finally installing the right side plate 2a, the operator needs to support these longer components with one hand simultaneously to align the positioning holes on the right side plate 2a with the positioning posts on these components. Because the positioning holes are small in diameter (approximately 6 mm), and because the mounting surfaces of the left side plate 1a and the right side plate 2a are deformed, it becomes very difficult and inconvenient to insert these longer components into the positioning holes simultaneously.

[0057] In addition, the six components—rapid-heating evaporator assembly, upper air inlet plate, volute, lower air inlet plate, volute casing, and impeller assembly—all have certain dimensional tolerances; for a half-meter-long part, the dimensional tolerance is approximately 5 millimeters. Due to these tolerances, the actual lengths of these components will vary. Figure 1 For example, the actual length of the volute tongue might be shortened by 3 mm due to tolerance, while the volute casing might be increased by 3 mm. In this case, after assembly, the upper mounting surfaces 3a and lower mounting surfaces 4a of the left side plate 1a and right side plate 2a, which should originally be parallel, will become twisted and no longer parallel due to the inconsistent lengths of the intermediate parts. As load-bearing components, if the left side plate 1a and right side plate 2a are significantly affected by twisting, it will not only reduce their rigidity but also increase the overall tolerance of the entire frame assembly, causing interference with the installation of other parts of the machine.

[0058] During the installation process using left side panel 1a and right side panel 2a as the frame components of the overall structure, the following problems were discovered:

[0059] Deformation of left side plate 1a: Due to the flatness tolerance of the left side plate 1a, its upper mounting surface 3a and lower mounting surface 4a are slightly deformed and not flat enough. This causes deformation of the positioning holes and screw mounting holes on the left side plate 1a, which in turn causes a slight tilt when installing the fast-heating evaporator assembly, upper air inlet plate, impeller assembly, volute tongue, volute, and lower air inlet plate.

[0060] Parts tolerance deformation: The fast evaporator assembly, upper air inlet plate, impeller assembly, volute tongue, volute, lower air inlet plate and other parts may also be slightly deformed due to tolerance, which will further affect the assembly accuracy of the right side plate 2a.

[0061] The difficulty of inserting the parts into the right side plate 2a: It is very difficult to simultaneously insert six parts, each more than half a meter long, into the positioning holes of the right side plate 2a. Due to the length of the parts, it is difficult to place them stably during the insertion process.

[0062] Cumulative error: Due to component deformation and cumulative errors during installation with the left side plate 1a, the six middle parts are difficult to position and secure correctly. Simultaneously, the right side plate 2a itself deforms, making it even more difficult to insert the right side plate 2a into the six middle parts.

[0063] Contact surface issues after installation: After installation, due to dimensional tolerances in the lengths of six components—the fast-heating evaporator assembly, upper air inlet plate, impeller assembly, volute, volute casing, and lower air inlet plate—the contact surface between the right side plate 2a and the middle components is uneven. The longest component has the most contact, while the other components have less contact. After fixing each component to the right side plate 2a with screws, the right side plate 2a deforms due to the inconsistent lengths of the six middle components caused by the screw tightening force.

[0064] Stiffness is affected: Due to the inconsistent basic lengths of the six middle parts, the contact surfaces of the left side plate 1a and the right side plate 2a with the middle parts are not on the same plane. After installation, the right side plate 2a will twist under stress, thus affecting its stiffness.

[0065] These problems combined make the assembly process complex and prone to deviations, affecting the stability and performance of the overall structure.

[0066] The following is combined with Figures 1 to 17 The following describes embodiments of the present invention.

[0067] According to an embodiment of the present invention, a heating assembly is provided, including an upper frame assembly 1 and a lower frame assembly 2.

[0068] The upper frame assembly 1 includes a first upper side plate 101, a second upper side plate 102, an upper air inlet plate 103, a volute 104, and an evaporator assembly 105. The upper air inlet plate 103, the volute 104, and the evaporator assembly 105 have the same assembly length and are all assembled between the first upper side plate 101 and the second upper side plate 102. The lower frame assembly 2 includes a first lower side plate 201, a second lower side plate 202, a lower air inlet plate 203, a volute 204, and a fan wheel assembly 205. The lower air inlet plate 203, the volute 204, and the fan wheel assembly 205 have the same assembly length and are all assembled between the first lower side plate 201 and the second lower side plate 202. The lower frame assembly 2 is connected to the upper frame assembly 1.

[0069] In this embodiment, the first upper side plate 101 and the first lower side plate 201 are separate structures, and the second upper side plate 102 and the second lower side plate 202 are also separate structures. The upper air inlet plate 103, the volute 104, and the evaporator assembly 105 have the same assembly length and are all assembled between the first upper side plate 101 and the second upper side plate 102 to form the upper frame assembly 1. The lower air inlet plate 203, the volute 204, and the impeller assembly 205 have the same assembly length and are all assembled between the first lower side plate 201 and the second lower side plate 202 to form the lower frame assembly 2. The individual first upper side plate 101, first lower side plate 201, second upper side plate 102, and second lower side plate 202 are not easily twisted. During assembly, the upper frame assembly 1 and the lower frame assembly 2 are assembled separately. Since the upper air inlet plate 103, the volute tongue 104 and the evaporator assembly 105 have the same assembly length, the assembly difficulty of the upper frame assembly 1 alone is relatively low. Since the lower air inlet plate 203, the volute 204 and the impeller assembly 205 have the same assembly length, the assembly difficulty of the lower frame assembly 2 is relatively low. Therefore, the overall assembly difficulty can be reduced.

[0070] Compared with related technologies, this embodiment divides the left side plate 1a into a first upper side plate 101 and a first lower side plate 201, and the right side plate 2a into a second upper side plate 102 and a second lower side plate 202, which can avoid the twisting and deformation of the left side plate 1a and the right side plate 2a due to part size errors.

[0071] It should be noted that the assembly length of the upper air inlet plate 103, the volute tongue 104 and the evaporator assembly 105 refers to the length between the first upper side plate 101 and the second upper side plate 102, and the assembly length of the lower air inlet plate 203, the volute 204 and the impeller assembly 205 refers to the length between the first lower side plate 201 and the second lower side plate 202.

[0072] It should be noted that the evaporator assembly 105 is the heating element; the upper air inlet plate 103, the volute tongue 104, the lower air inlet plate 203, and the volute 204 constitute the air duct system; the impeller assembly 205 provides forced airflow.

[0073] In one embodiment, such as Figure 7 As shown, the upper air intake plate 103 and the volute tongue 104 are assembled to form a first assembly unit, which is assembled between the first upper side plate 101 and the second upper side plate 102.

[0074] In this embodiment, the upper air inlet plate 103 and the volute tongue 104 are pre-assembled into a first assembly unit. The first assembly unit is assembled as a whole with the evaporator assembly 105 between the first upper side plate 101 and the second upper side plate 102, which makes assembly easier and can effectively reduce the problem of twisting and deformation caused by errors of individual components.

[0075] It should be noted that, since the upper air inlet plate 103 and the volute tongue 104 are assembled into the first assembly unit, when assembling the first assembly unit between the first upper side plate 101 and the second upper side plate 102, the upper air inlet plate 103 can be connected only to the first upper side plate 101 and the second upper side plate 102, or the volute tongue 104 can be connected only to the first upper side plate 101 and the second upper side plate 102.

[0076] In one specific embodiment, the upper air inlet plate 103 and the volute tongue 104 are assembled into a first assembly unit. The two sides of the upper air inlet plate 103 are connected to the first upper side plate 101 and the second upper side plate 102, respectively. The volute tongue 104 does not need to be connected to the first upper side plate 101 and the second upper side plate 102. After the upper air inlet plate 103 and the volute tongue 104 are assembled into the first assembly unit, one side of the upper air inlet plate 103 is first connected to the first upper side plate 101, and then the second upper side plate 102 is connected to the other side of the upper air inlet plate 103. Therefore, the dimensional accuracy of the upper frame assembly 1 mainly depends on the upper air inlet plate 103. The dimensional accuracy of the volute tongue 104 has no impact on the assembly accuracy of the upper frame assembly 1, thus improving the assembly accuracy of the upper frame assembly 1.

[0077] Specifically, the upper air inlet plate 103 has flanges on both sides, and the flanges are connected to the first upper side plate 101 and the second upper side plate 102 by screws.

[0078] In one specific embodiment, the upper air intake plate 103 and the volute tongue 104 are connected by screws and / or clips.

[0079] In one specific embodiment, the upper air inlet plate 103 includes a first inclined plate 1031, a second inclined plate 1032 and a vertical plate 1033 connected sequentially from top to bottom. The angle between the first inclined plate 1031 and the horizontal plane is greater than the angle between the second inclined plate 1032 and the horizontal plane. The vertical plate 1033 is connected to the volute tongue 104.

[0080] In one embodiment, the evaporator assembly 105 includes an evaporator 1051, a first support structure, and a second support structure. The first end of the evaporator 1051 is axially movable relative to the first support structure, and the second end of the evaporator 1051 is fixed to the second support structure. The first support structure is connected to the first upper side plate 101, and the second support structure is connected to the second upper side plate 102.

[0081] In this embodiment, since the first end of the evaporator 1051 can move axially relative to the first support structure, and the second end of the evaporator 1051 is fixed to the second support structure, the first support structure is connected to the first upper side plate 101, and the second support structure is connected to the second upper side plate 102, the assembly difficulty caused by dimensional tolerances can be reduced, and the second upper side plate 102 can be tightly fitted with the upper air inlet plate 103.

[0082] Specifically, when the evaporator assembly 105 is longer or shorter than the upper air inlet plate 103 due to manufacturing tolerances, during assembly, the first support structure is first fixedly connected to the first upper side plate 101, the first assembly assembly is fixedly connected to the first upper side plate 101, and then the second upper side plate 102 is assembled. Since the first end of the evaporator 1051 can move axially relative to the first support structure, the position of the evaporator 1051 can be adjusted to match the assembly length of the upper air inlet plate 103, so that the second upper side plate 102 can fit tightly with the upper air inlet plate 103.

[0083] In one embodiment, the first support structure includes a first support 1052 and a first support cover 1053, and the second support structure includes a second support 1054 and a second support cover 1055. The first end of the evaporator 1051 is disposed between the first support 1052 and the first support cover 1053, and the second end of the evaporator 1051 is disposed between the second support 1054 and the second support cover 1055.

[0084] In this embodiment, the first support structure includes a first support 1052 and a first support cover 1053, and the second support structure includes a second support 1054 and a second support cover 1055, which facilitates limiting the two ends of the evaporator 1051.

[0085] Specifically, the first end of the evaporator 1051 is provided with two tubular joints, which are clamped between the first support 1052 and the first support cover 1053. The second end of the evaporator 1051 is also provided with two tubular joints, which are clamped between the second support 1054 and the second support cover 1055.

[0086] Specifically, the evaporator 1051 is a fast-heating evaporator 1051.

[0087] In one specific embodiment, the first bracket cover 1053 and the first bracket 1052 are connected by screws and / or snaps; the second bracket cover 1055 and the second bracket 1054 are connected by screws and / or snaps.

[0088] In one embodiment, such as Figures 8 to 10 The second end of the evaporator 1051 is provided with a positioning post 10511, and the second bracket 1054 is provided with a positioning groove 10541, with the positioning post 10511 embedded in the positioning groove 10541.

[0089] In this embodiment, the second end of the evaporator 1051 is provided with a positioning post 10511, and the second bracket 1054 is provided with a positioning groove 10541. The positioning post 10511 is embedded in the positioning groove 10541, which facilitates the limiting and fixing of the second end of the evaporator 1051.

[0090] In one embodiment, such as Figure 13 and Figure 14 The first lower side plate 201 is provided with a mounting through hole, and a bearing housing assembly 206 is provided in the mounting through hole. The end of the impeller assembly 205 away from the motor 207 is located in the bearing housing assembly 206.

[0091] In this embodiment, a mounting through hole is provided in the first lower side plate 201, and a bearing housing assembly 206 is provided in the mounting through hole. The end of the impeller assembly 205 away from the motor 207 is located in the bearing housing assembly 206. Therefore, the impeller assembly 205 can move axially relative to the mounting through hole, ensuring that the assembly of the lower frame assembly 2 is not affected by the dimensional tolerance of the impeller assembly 205.

[0092] Specifically, the end of the wind turbine assembly 205 away from the motor 207 is provided with a rotating shaft 2051, which can move relative to the bearing housing assembly 206.

[0093] Specifically, the motor 207 is located on the side of the second lower side plate 202 away from the first lower side plate 201.

[0094] In one embodiment, such as Figure 16 As shown, the lower air inlet plate 203 and the volute 204 are assembled to form a second assembly unit, which is assembled between the first lower side plate 201 and the second lower side plate 202.

[0095] In this embodiment, the lower air inlet plate 203 and the volute 204 are pre-assembled into a second assembly unit. The second assembly unit is assembled as a whole with the impeller assembly 205 between the first lower side plate 201 and the second lower side plate 202, which makes assembly easier, reduces assembly difficulty, and can effectively reduce the problem of torsion and deformation caused by errors of various components.

[0096] It should be noted that since the lower air inlet plate 203 and the volute 204 are assembled into a second assembly unit, when assembling the second assembly unit between the first lower side plate 201 and the second lower side plate 202, only the lower air inlet plate 203 can be connected to the first lower side plate 201 and the second lower side plate 202, or only the volute 204 can be connected to the first lower side plate 201 and the second lower side plate 202. Alternatively, both the lower air inlet plate 203 and the volute 204 can be connected to the first lower side plate 201 and the second lower side plate 202, with the lower air inlet plate 203 positioned and fitted with the first lower side plate 201 and the second lower side plate 202, and the volute 204 connected to the first lower side plate 201 and the second lower side plate 202 by screws. Therefore, the dimensional accuracy of the lower frame assembly 2 mainly depends on the volute 204, thus improving the assembly accuracy of the lower frame assembly 2.

[0097] In one embodiment, the connection position of the first upper side plate 101 and the first lower side plate 201 is adjustable, and the connection position of the second upper side plate 102 and the second lower side plate 202 is adjustable.

[0098] In this embodiment, the connection position of the first upper side plate 101 and the first lower side plate 201 is adjustable, meaning that the connection position of the first upper side plate 101 and the first lower side plate 201 is not unique. This can prevent twisting and deformation of the first upper side plate 101 and the first lower side plate 201 when they are connected due to dimensional errors. The connection position of the second upper side plate 102 and the second lower side plate 202 is also adjustable, meaning that the connection position of the second upper side plate 102 and the second lower side plate 202 is not unique. This can prevent twisting and deformation of the second upper side plate 102 and the second lower side plate 202 when they are connected due to dimensional errors.

[0099] In one embodiment, one of the first upper side plate 101 and the first lower side plate 201 is provided with a circular hole, and the other of the first upper side plate 101 and the first lower side plate 201 is provided with an elongated hole 2021. Fasteners pass through the circular hole and the elongated hole 2021 to connect the first upper side plate 101 and the first lower side plate 201. One of the second upper side plate 102 and the second lower side plate 202 is provided with a circular hole, and the other of the second upper side plate 102 and the second lower side plate 202 is provided with an elongated hole 2021. Fasteners pass through the circular hole and the elongated hole 2021 to connect the second upper side plate 102 and the second lower side plate 202.

[0100] In this embodiment, by providing a circular hole in one of the first upper side plate 101 and the first lower side plate 201, and an elongated hole 2021 in the other of the first upper side plate 101 and the first lower side plate 201, and by having fasteners pass through the circular hole and the elongated hole 2021 to connect the first upper side plate 101 and the first lower side plate 201, twisting deformation due to dimensional errors during the connection of the first upper side plate 101 and the first lower side plate 201 can be avoided. Similarly, by providing a circular hole in one of the second upper side plate 102 and the second lower side plate 202, and an elongated hole 2021 in the other of the second upper side plate 102 and the second lower side plate 202, and by having fasteners pass through the circular hole and the elongated hole 2021 to connect the second upper side plate 102 and the second lower side plate 202, twisting deformation due to dimensional errors during the connection of the second upper side plate 102 and the second lower side plate 202 can be avoided.

[0101] In one specific embodiment, the first lower side plate 201 and the second lower side plate 202 are provided with an elongated hole 2021.

[0102] In an alternative embodiment, a plurality of first connecting holes may be provided on the first upper side plate 101, and a second connecting hole may be provided on the first lower side plate 201. During assembly, the second connecting hole and one of the first connecting holes may be aligned as needed, and the fastener may pass through the second connecting hole and the first connecting hole to achieve a fixed connection between the first upper side plate 101 and the first lower side plate 201.

[0103] In an alternative embodiment, a plurality of third connecting holes may be provided on the second upper side plate 102, and a fourth connecting hole may be provided on the second lower side plate 202. During assembly, the fourth connecting hole and one of the third connecting holes may be aligned as needed, and the fastener may pass through the fourth connecting hole and the third connecting hole to achieve a fixed connection between the second upper side plate 102 and the second lower side plate 202.

[0104] According to an embodiment of the present invention, in a second aspect, a household appliance is provided, including the heating component provided in the above embodiments.

[0105] In this household appliance, the first upper side panel 101 and the first lower side panel 201 are separate structures, and the second upper side panel 102 and the second lower side panel 202 are also separate structures. The upper air inlet plate 103, the volute 104, and the evaporator assembly 105 have the same assembly length and are all assembled between the first upper side panel 101 and the second upper side panel 102 to form the upper frame assembly 1. The lower air inlet plate 203, the volute 204, and the impeller assembly 205 have the same assembly length and are all assembled between the first lower side panel 201 and the second lower side panel 202 to form the lower frame assembly 2. The individual first upper side panel 101, first lower side panel 201, second upper side panel 102, and second lower side panel 202 are not easily twisted. During assembly, the upper frame assembly 1 and the lower frame assembly 2 are assembled separately. Since the upper air inlet plate 103, the volute tongue 104 and the evaporator assembly 105 have the same assembly length, the assembly difficulty of the upper frame assembly 1 alone is relatively low. Since the lower air inlet plate 203, the volute 204 and the impeller assembly 205 have the same assembly length, the assembly difficulty of the lower frame assembly 2 is relatively low. Therefore, the overall assembly difficulty can be reduced.

[0106] In one specific embodiment, the household appliance is a baseboard heater, a fan heater, an oil-filled radiator, etc.

[0107] According to an embodiment of the present invention, in a third aspect, a method for assembling a heating component is provided, for assembling the heating component provided in the above embodiments, the assembly method comprising:

[0108] The first upper side plate 101, the second upper side plate 102, the upper air inlet plate 103, the volute tongue 104 and the evaporator assembly 105 are assembled into the upper frame assembly 1;

[0109] The first lower side plate 201, the second lower side plate 202, the lower air inlet plate 203, the volute 204 and the impeller assembly 205 are assembled into the lower frame assembly 2;

[0110] Connect the lower frame component 2 to the upper frame component 1.

[0111] In this embodiment, during assembly, the upper frame assembly 1 and the lower frame assembly 2 are assembled separately. Since the upper air inlet plate 103, the volute 104, and the evaporator assembly 105 have the same assembly length, the assembly difficulty of the upper frame assembly 1 alone is relatively low. Since the lower air inlet plate 203, the volute 204, and the impeller assembly 205 have the same assembly length, the assembly difficulty of the lower frame assembly 2 is relatively low. Therefore, the overall assembly difficulty can be reduced. Compared with related technologies, dividing the left side plate 1a into a first upper side plate 101 and a first lower side plate 201, and dividing the right side plate 2a into a second upper side plate 102 and a second lower side plate 202, can avoid the twisting and deformation of the left side plate 1a and the right side plate 2a due to part size errors.

[0112] It should be noted that connecting the lower frame component 2 to the upper frame component 1 specifically means connecting the first upper side plate 101 to the first lower side plate 201, and connecting the second upper side plate 102 to the second lower side plate 202.

[0113] In one embodiment, assembling the first upper side plate 101, the second upper side plate 102, the upper air inlet plate 103, the volute 104, and the evaporator assembly 105 into the upper frame assembly 1 includes:

[0114] The upper air intake plate 103 and the volute tongue 104 are assembled to form the first assembly unit;

[0115] Connect the first assembly unit, the evaporator assembly 105, and the first upper side plate 101;

[0116] The second upper side plate 102 is connected to the first assembly unit and the evaporator assembly 105.

[0117] In this embodiment, the upper air inlet plate 103 and the volute tongue 104 are pre-assembled into a first assembly unit. The first assembly unit is assembled as a whole with the evaporator assembly 105 between the first upper side plate 101 and the second upper side plate 102, which makes assembly easier and can effectively reduce the problem of twisting and deformation caused by errors of individual components.

[0118] In one embodiment, assembling the first lower side plate 201, the second lower side plate 202, the lower air inlet plate 203, the volute 204, and the impeller assembly 205 into the lower frame assembly 2 includes:

[0119] The lower air inlet plate 203 and the volute 204 are assembled to form the second assembly unit;

[0120] Connect the second assembly unit and the wind turbine assembly 205 to the first lower side plate 201;

[0121] Connect the second lower side plate 202 to the second assembly unit and the wind turbine assembly 205.

[0122] The lower air inlet plate 203 and the volute 204 are pre-assembled into a second assembly unit. The second assembly unit is assembled as a whole with the impeller assembly 205 between the first lower side plate 201 and the second lower side plate 202, which makes assembly easier, reduces assembly difficulty, and can effectively reduce the problem of torsion and deformation caused by errors of various parts.

[0123] Although embodiments of the present 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 present invention, and such modifications and variations all fall within the scope defined by this application.
