If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0047] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0048] The present application provides an electric heating device. Specifically, the electric heating device provided by the present application is applied to air handling equipment, and the air handling equipment may be a duct air conditioner.

[0049] Please refer to Figure 1 and Figure 2 , Figure 1 This is a partial structural schematic diagram of an air treatment device according to an embodiment of the utility model. Figure 2 The electric heating device 10 comprises an electric control component 200 and a heating component 100 , wherein the heating component 100 is configured to generate heat when powered by the electric control component 200 .

[0050] Please refer to Figure 3 and Figure 4 , Figure 3 A schematic diagram of the structure of the heating assembly of the utility model embodiment when the holding member is in the first position, Figure 4The heating assembly 100 includes a support member 110 and a heating mechanism 120 , and the heating mechanism 120 is mounted on the support member 110 .

[0051] Among them, the heating mechanism 120 is the core component of the heating component 100. The heating mechanism 120 is electrically connected to the electric control component 200. When the heating mechanism 120 is powered on, a large amount of heat is generated to heat the air in the housing 20 of the air handling device 1000. The heating mechanism 120 includes a mounting portion 121 and a heating portion 122 connected to the mounting portion 121. The heating portion 122 includes a heating element 1221. The heating element 1221 is formed by a heating wire wound in a spiral manner. There are multiple heating elements 1221, and each heating element 1221 is cylindrical. The mounting portion 121 includes a mounting plate 1211 and multiple brackets 1212 connected to the mounting plate 1211. The heating element 1221 is fixedly connected to the bracket 1212. Each heating part 122 is also provided with a thermostat 1222 and a fuse 1223. The thermostat 1222 and the fuse 1223 are fixedly connected to one side of the mounting plate 1211, and the heating wire is located on the other side of the mounting plate 1211, so that the heating wire is separated from the thermostat 1222 and the fuse 1223. The two ends of the heating wire are respectively connected to the thermostat 1222 and the fuse 1223. The current enters from the thermostat 1222, flows out from the fuse 1223 after passing through the heating wire, and the heating temperature of the heating wire can be detected in real time by using the thermostat 1222. The output power can be adjusted according to the detected temperature value to achieve the control of the heating temperature. When the heating wire has a short circuit or other faults, the excessive current will trigger the fuse 1223 to disconnect the power supply, meeting the requirements of safety protection.

[0052] The support member 110 is used to position and support the heating mechanism 120. Figure 3 As shown, in one embodiment, the support member 110 is designed to be plate-shaped, and the support member 110 includes a first surface 111 and a second surface (not shown) opposite to each other, and the support member 110 is provided with an opening, and the opening passes through the first surface 111 and the second surface. Specifically, the mounting plate 1211 of the heating mechanism 120 is connected to the first surface 111, and the heating portion 122 passes through the opening to the side of the second surface.

[0053] In the related art, on a traditional duct-type air conditioner, the electric heating tube assembly and the control switch of the electric auxiliary heating device are usually assembled as a whole, and only a buckle structure is formed on the outer shell of the electric auxiliary heating device to facilitate installation in the factory. When the electric heating tube assembly needs to be maintained after sales (for example, adding electric heating tubes), the electric heating wire or the fixing structure on the electric heating tube assembly is generally grasped to remove the electric heating tube assembly, which is inconvenient for operators to grasp, affecting installation or disassembly, and it is easy for the heating tube assembly to fall and be damaged due to unstable grasping.

[0054] In this regard, in the embodiment of the present application, the heating assembly 100 further includes a grip 130 (also referred to as a handle), which is connected to the support member 110. The grip 130 is used for a human hand to hold and cooperate, so that the operator can grasp and lift the heating assembly 100. Of course, in some embodiments, the grip 130 can also be designed to cooperate with a tool.

[0055] The provision of the holding piece 130 facilitates the gripping of the heating component 100, so that the operator can lift the entire heating component 100 firmly through the holding piece 130, and the installation and disassembly of the heating component 100 is convenient, especially in the after-sales maintenance process, under limited after-sales operating conditions (compared to factory assembly), the difficulty of installing and disassembling the heating component 100 is reduced, the efficiency of after-sales maintenance can be improved, and user recognition can be improved.

[0056] However, the holding member 130 will occupy the space on one side of the support member 110, increasing the overall volume of the heating component 100. In order to reduce the internal space occupied by the heating component 100 of the air treatment device 1000, in an embodiment of the present application, the holding member 130 is movably connected to the support member 110, and the holding member 130 can move and switch between the first position and the second position under the action of an external force.

[0057] Please refer to Figure 3 The holding member 130 includes a holding portion 131. When in the first position, the holding portion 131 is spaced apart from the first surface 111 and a hand-gripping gap is formed.

[0058] Specifically, when the gripping portion 131 is in the first position, it is spaced from the first surface 111 to form a hand-gripping gap, so that the after-sales operator can pass the hand-gripping gap with the gripping portion 131 to cooperate with the operator, so that the operator can lift the entire heating component 100. In other words, the first position is the gripping position of the gripping member 130. For example, when the after-sales operator needs to add a heating wire to the heating component 100, the gripping portion 131 is moved to the first position and held by hand to facilitate taking the heating component 100 out of the housing 20. Similarly, after the maintenance of the heating component 100 is completed, the operator can lift the entire heating component 100 through the gripping portion 131 and install it into the housing 20, so that the operator can easily complete the installation and removal of the heating component 100 by one person.

[0059] Please refer to Figure 5 , Figure 5This is a schematic diagram of the structure of the heating component of an embodiment of the utility model when the grip is in the second position. In the second position, the grip portion 131 is against the first surface 111. In this way, the hand-clasping gap between the grip portion 131 and the first surface 111 disappears when the grip is in the second position, and the grip 130 cannot be grasped at this time. This position can be used as the position of the grip 130 when not in use, that is, the storage position. Then, when it is not needed, the grip 130 is moved to the second position so that the grip 131 is against the first surface 111, which reduces the space occupied by the grip 131 on one side of the first surface 111. After the heating component 100 is installed in the shell 20 of the air treatment device 1000, the operator can move the grip 131 to the second position, which can reduce the occupation of the internal space of the shell 20.

[0060] The heating component of the embodiment of the present application is configured to be movably connected with the support member 110 by setting a holding member 130 so that the holding member 130 can be moved and switched between a first position and a second position. When in the first position, a hand-gripping gap is formed between the holding member 130 and the first surface 111 of the support member 110, which is convenient for the operator to hold and is conducive to the installation or removal of the heating component 100. When in the second position, the holding member 130 is abutted against the first surface 111, thereby reducing the overall volume of the heating component 100. When the heating component 100 is installed in the air treatment device 1000, the holding member 130 is moved to the second position, thereby reducing the occupation of the internal space of the air treatment device 1000.

[0061] In traditional duct air conditioners, the electric heating tube and control switch of the electric auxiliary heating device are assembled as a whole. In order to meet the requirement of uniform heating of the air in the shell, the electric heating tube is usually set in the center. Since the control switch and the electric heating tube are assembled as a whole, the installation of the control switch is passive. Especially for series products, air conditioners usually provide different specifications and models according to different cooling requirements. The installation positions of the control switches on shells of different sizes vary greatly, affecting the consistency of the series products. If the control switch is installed in the required position according to the series design, the electric heating tube is difficult to meet the requirement of central placement, and the assembly positions of the electric heating tube and the control switch cannot be taken into account.

[0062] In this regard, in one embodiment of the present application, the electric control component 200 and the heating component 100 are separately arranged, and the electric control component 200 is electrically connected to the heating component 100 through a flexible cable (not shown in the figure). It should be noted that the separate arrangement here means that the electric control component 200 and the heating component 100 are two separate independent functional modules, the electric control component 200 and the heating component 100 are not assembled as a whole, and the electric control component 200 and the heating component 100 are only electrically connected through a flexible cable. Before the two are assembled with the housing 20 of the air treatment device 1000, the electric control component 200 and the heating component 100 can generate relative movement under the action of external force; and the two can be assembled and disassembled separately.

[0063] In this embodiment, the heating component 100 and the electric control component 200 are separately arranged, and the two can be installed and removed independently. The electric control component 200 will not be restrained by the heating component 100, and similarly, the heating component 100 will not be restrained by the electric control component 200, so that the heating component 100 and the electric control component 200 can be installed at the required position. Especially for series products, different specifications and models are provided, and the electric control component 200 can be assembled to the same position (or substantially the same) of different models of products, reducing the differences between different models of products, facilitating product production, and achieving coordination and consistency in the appearance of series products.

[0064] Please refer to Figure 2 The electric control component 200 includes a mounting member 210 and an electric control element connected to the mounting member 210, such as an air switch 220. Since the air switch 220 requires manual operation under normal circumstances, the present application separates the heating component 100 and the electric control component 200, so that the electric control component 200 can be installed in a position that is convenient for manual access according to usage requirements, which is convenient for operation by users or operators.

[0065] It should also be pointed out that in this embodiment, the heating component 100 and the electronic control component 200 are separately arranged, and a gripping piece 130 is also provided for the heating component 100, which makes it more convenient to install and disassemble the heating component 100 separately, further improves the efficiency of after-sales maintenance, and improves user recognition.

[0066] In one embodiment, the grip 130 is rotatably connected to the support 110 to switch between the first position and the second position. It should be noted that the grip 130 and the support 110 are rotatably connected, and the grip 130 and the support 110 can be directly rotatably connected, or the grip 130 and the support 110 can be indirectly rotatably connected, for example, the grip 130 can be rotatably connected to a connection structure provided on the support 110. In order to form a hand-gripping gap between the grip 131 and the first surface 111 when the grip 130 is in the first position, the rotation axis of the grip 130 is parallel to the first surface 111.

[0067] For more information, see Figure 6 , Figure 6 The figure is a schematic diagram of the assembly of the support member and the gripping member of the embodiment of the utility model. The gripping member 130 may include a connecting portion 132, one end of which is rotatably disposed on the support member 110, and the other end is connected to the gripping member 131. The connecting portion 132 rotates relative to the support member 110 under the action of an external force, thereby driving the gripping member 131 to rotate and switch between the first position and the second position. For one gripping member 130, there are two connecting portions 132, and the two connecting portions 132 are respectively connected to the two ends of the gripping member 131, such as Figure 6 As shown, the holding member 130 is generally in the shape of a "]".

[0068] The mounting plate 1211 of the heating mechanism 120 is connected to the first surface 111. Specifically, the support member 110 is provided with a first connection hole (not shown) penetrating the first surface 111 and the second surface, and the mounting plate 1211 is connected to the first surface 111 via a fastener penetrating the first connection hole. In this way, the mounting plate 1211 of the heating mechanism 120 is located on the first surface 111.

[0069] In one embodiment, please combine Figure 3 , Figure 5 And refer to Figure 7 and Figure 8 , Figure 7 This is a top view of the heating assembly of the utility model embodiment when the holding member is in the first position. Figure 8 This is a top view of the heating assembly of the present invention when the grip is in the second position. In the first position, at least part of the orthographic projection of the grip 131 on the first surface 111 is located within the orthographic projection of the heating mechanism 120 on the first surface 111, and the grip 131 is spaced apart from the heating mechanism 120; in the second position, the orthographic projection of the grip 131 on the first surface 111 is located outside the orthographic projection of the heating mechanism 120 on the first surface 111.

[0070] For the convenience of explanation, the first surface 111 is used as a reference surface, and the side of the first surface 111 facing away from the second surface is defined as the upper side of the support member 110. When the gripping member 130 is in the first position, the orthographic projection of at least part of the gripping portion 131 on the first surface 111 is located in the first area, and the gripping portion 131 is spaced apart from the heating mechanism 120, which means that at least part of the gripping portion 131 is located directly above the heating mechanism 120, that is, directly above the mounting plate 1211. Then, when the gripping portion 131 is in the first position, the space directly above the heating mechanism 120 is utilized, thereby improving the space utilization rate. There is no need to design the area of ​​the support member 110 to be large for installing the gripping member 130, which can reduce the area of ​​the support member 110, reduce the overall volume of the heating assembly 100, and further reduce the occupation of the internal space of the air treatment device 1000.

[0071] When the grip 130 is in the second position, the orthographic projection of the grip 131 on the first surface 111 is located outside the orthographic projection of the heating mechanism 120 on the first surface 111, that is, the grip 131 is located in the outer space except for the space directly above the heating mechanism 120, and there is no obstruction in the square space of the heating mechanism 120. In other words, when the grip 130 is in the second position, there is no other obstruction in the space area on the first surface 111 where the heating mechanism 120 is installed, which facilitates the installation or removal of the heating mechanism 120. Then, when installing or removing the heating mechanism 120, the grip 130 is moved to the second position to facilitate the smooth installation and removal of the heating mechanism 120. In particular, during the production process within the factory, the support member 110 and the holding member 130 are often produced at one workstation, while the heating mechanism 120 is produced at another workstation, and finally assembled. Through the above arrangement, the present embodiment allows the holding member 130 to be moved to the second position during the final assembly process, so that the heating mechanism 120 can smoothly pass through the opening 112 and be installed with the support member 110, which will not affect the assembly progress and can improve production efficiency.

[0072] The support member 110 is provided with a mounting hole 115, which passes through the first surface 111 and the second surface. The support member 110 is used to be connected to the housing 20 of the air treatment device 1000 through a fastener (such as a screw) passing through the mounting hole 115. In order to facilitate the installation and removal of the heating component 100 itself and the housing 20, in one embodiment, please continue to refer to Figure 7 and Figure 8 When the holding member 130 is in the first position and the second position, the orthographic projection of the holding portion 131 on the first surface 111 is located on one side of the mounting hole 115 .

[0073] like Figure 7 and Figure 8As shown, no matter the gripping member 130 is in the first position or the second position, the mounting hole 115 can be directly seen from the top of the first surface 111 of the support member 110. That is to say, when the gripping member 130 is in the first position and the second position, the gripping portion 131 avoids the mounting hole 115, and the gripping portion 131 does not block the top of the mounting hole 115, so that a space for human hands or tools to operate is reserved above the mounting hole 115, which can facilitate the operator to screw the screws in the mounting hole 115, facilitate the operator to operate, facilitate the installation and disassembly of the heating assembly 100 as a whole, and further improve the production efficiency or the efficiency of later maintenance.

[0074] In addition, it is also necessary to point out that the above-mentioned embodiment of the present application sets the holding member 130 in the first position so that at least a part of the holding portion 131 is located directly above the heating mechanism 120, so that the holding portion 131 can be away from the mounting hole 115, which not only saves space but also makes it easier to achieve that the mounting hole 115 is not blocked when the holding member 130 is in the first position, which has two functions.

[0075] In one embodiment, there are two gripping members 130, and the two gripping members 130 are arranged at a relative interval. With two gripping members 130, the operator can hold the gripping members 130 with both hands to lift the heating assembly 100 steadily, thereby improving the stability of the installation or removal of the heating assembly 100.

[0076] In one embodiment, the heating component 100 is configured as follows: when the heating component 100 is installed in the shell 20 of the air treatment device 1000, the two gripping members 130 are relatively spaced apart along the width direction of the shell 20, that is, the two gripping members 130 are relatively arranged along the horizontal direction, so that the two gripping members 130 are adapted to the positions of the left and right hands of the human body, which is more conducive to the operator's gripping, further reducing the difficulty of installation and disassembly of the heating component 100, and can improve the efficiency of after-sales maintenance.

[0077] In order to prevent the holding piece 130 from moving due to vibration and contacting electrical components on the heating mechanism 120, especially to prevent the holding piece 130 from contacting electrical components on the mounting plate 1211, in one embodiment, the heating assembly 100 also includes a limiting mechanism, which is arranged on the support member 110, and the limiting mechanism is used to limit the holding piece 130 to the first position.

[0078] It can be understood that there can be many specific structures of the limiting mechanism. The limiting mechanism can be a rigid limiting structure. For example, the limiting mechanism can include a limiting plate, and the limiting plate is arranged on the rotation path of the connecting portion 132. When the holding member 130 is rotated to the first position, the limiting plate and the connecting portion 132 of the holding member 130 are limited and cooperated to prevent the connecting portion 132 from continuing to rotate, thereby limiting the holding member 130 to the first position. The limiting mechanism may also be an elastic limiting structure. For example, the limiting mechanism may include an elastic member and a limiting pin connected to the elastic member. A limiting hole is provided on the connecting portion 132 of the gripping member 130. The spatial position of the limiting hole changes with the rotation of the connecting portion 132. In other positions, the limiting pin abuts against the connecting portion 132 under the elastic force of the elastic member. When the gripping member 130 is rotated to the first position, the limiting hole corresponds to the limiting pin. The limiting pin is inserted into the limiting hole under the elastic force of the elastic member. The limiting pin limits the freedom of rotation of the connecting portion 132, thereby limiting the gripping member 130 to the first position.

[0079] In order to simplify the overall structure of the heating assembly 100, in one embodiment, please combine Figure 6 And refer to Fig. 9 , Fig. 9 for Figure 6 A partial enlarged view of the position A in the middle. The limiting mechanism 140 includes a connecting plate 141 and a limiting portion 142. The connecting plate 141 is connected to the first surface 111, and the connecting portion 132 is rotatably connected to the connecting plate 141. Among them, a second connecting hole can be provided on the connecting plate 141, and the connecting portion 132 is rotatably connected to the connecting plate 141 through a pin shaft penetrating the second connecting hole, so that the connecting portion 132 rotates relative to the connecting plate 141 around the axis of the pin shaft, thereby driving the gripping portion 131 to rotate.

[0080] The limiting portion 142 is disposed on the connecting plate 141. Fig. 9 As shown, the limiting portion 142 protrudes from the surface of the connecting plate 141, and when the gripping member 130 rotates to the first position, the limiting portion 142 abuts against the connecting portion 132. The limiting portion 142 can be designed as a plate, a block, a column, etc.

[0081] In this way, by setting the limiting portion 142, when the holding member 130 rotates to the first position, the limiting portion 142 abuts against the connecting portion 132, limiting the freedom of the connecting portion 132 to continue to rotate toward the side of the heating mechanism 120, thereby limiting the holding member 130 to the first position. When the holding member 130 is in the first position and rotates due to a large vibration, the limiting portion 142 prevents the holding member 130 from rotating toward the side of the heating mechanism 120, so that the holding member 130 can only move in the direction away from the heating mechanism 120, preventing the holding member 130 (especially the holding portion 131) from contacting and conducting with the electrical components on the heating mechanism 120, avoiding the short circuit of the heating mechanism 120, preventing the heating mechanism 120 from being damaged by a short circuit, and preventing the current from being conducted to other components through the holding member 130 to cause leakage, thereby improving the safety of the heating assembly 100.

[0082] Among them, the limiting portion 142 is arranged on the connecting plate 141, and the connecting plate 141 is rotatably connected with the connecting portion 132, so that the connecting plate 141 is not only used to support the limiting portion 142, but also the connecting plate 141 serves as the connecting portion 132 of the holding piece 130. That is, through the limiting mechanism 140 composed of the connecting plate 141 and the limiting portion 142, the two functions of connecting and limiting the holding piece 130 are realized, which can simplify the overall structure of the heating component 100, facilitate processing and manufacturing, and improve production efficiency.

[0083] To further improve the production and processing efficiency, in one embodiment, the limiting portion 142 is configured to be plate-shaped, such as Fig. 9 As shown, the connecting plate 141 is bent and formed at the outer edge of the supporting member 110, and the limiting portion 142 is bent and formed at the side edge of the connecting plate 141, so that the connecting plate 141, the limiting portion 142 and the supporting member 110 are an integrally bent structure, which can be processed and formed in the same processing step, greatly improving the processing efficiency.

[0084] In order to facilitate the processing and manufacturing of the gripping member 130, the gripping member 130 can be made of a plate, and the plate is processed into the above-mentioned shape through a bending process. The processing process is simple, fast, and low in cost. Figure 6 The holding piece 130 further includes a first folded edge 133 , which is bent at the outer edge of the holding portion 131 , and the first folded edge 133 is in contact with the surface of the holding portion 131 .

[0085] Then, by providing the first folded edge 133 at the edge of the gripping portion 131 and arranging the first folded edge 133 to fit the surface of the gripping portion 131, on the one hand, the local thickness of the gripping portion 131 is increased, the overall strength of the gripping member 130 can be enhanced, and the overall bearing capacity of the gripping member 130 can be improved, thereby improving the anti-deformation ability of the gripping member 130 and preventing the gripping member 130 from deforming due to the weight of the support member 110 and the heating mechanism 120. On the one hand, the bending connection between the first folded edge 133 and the gripping portion 131 is an arc transition, which increases the contact area, prevents the operator's hand from being strangled by the edge of the gripping portion 131, improves the comfort of the operator's grip, and is more conducive to the operator lifting the heating assembly 100 for installation or removal.

[0086] In addition, since the first folded edge 133 is also formed by a bending process, the first folded edge 133 and the gripping portion 131 can be processed in the same processing step, reducing the transfer steps during the processing of the gripping piece 130 and further improving the processing efficiency of the gripping piece 130.

[0087] Continue to refer Figure 6 As shown, the outer edge of the support member 110 is bent to form a second folded edge 113. It can be understood that by providing the second folded edge 113, the overall strength of the support member 110 can be enhanced, the bearing capacity of the support member 110 can be improved, and the weight of the heating mechanism 120 can be prevented from acting entirely on the support member 110, causing the support member 110 to deform.

[0088] Among them, there can be many specific structural designs of the second folded edge 113, and this embodiment does not limit this. The second folded edge 113 can be set to extend in a direction perpendicular to the surface of the support member 110. For example, the second folded edge 113 can extend in a direction toward the side of the first surface 111 away from the second surface, or it can extend in a direction toward the side of the second surface away from the first surface 111. The second folded edge 113 can also be set to fit the surface of the support member 110. For example, the second folded edge 113 can be set to fit the first surface 111, or it can be set to fit the second surface. The structure of the second folded edge 113 shown in the drawings of this embodiment is for illustration only and cannot be regarded as a limitation of this application.

[0089] Please refer again Figure 6 The support member 110 further includes a third folded edge 114 , which is bent at a side edge of the opening 112 .

[0090] Similarly, a third folded edge 114 is formed at the side edge of the opening 112 to enhance the strength of the area near the opening 112, prevent the support member 110 from deforming and pulling the opening 112 to deform, avoid obstruction to the heating portion 122 of the heating mechanism 120 when passing through the opening 112, and ensure smooth installation or disassembly of the heating mechanism 120.

[0091] In one embodiment, the third folded edge 114 is located on the side of the first surface 111 facing the second surface, that is, the third folded edge 114 does not protrude from the first surface 111. In this way, the first surface 111 is designed to be flat, so that the mounting portion 121 of the heating mechanism 120 is connected to the first surface 111, thereby improving the installation efficiency. The third folded edge 114 can extend in a direction away from the first surface 111 toward the second surface, or can be arranged to fit the second surface, which is not limited in the embodiment of the present application.

[0092] The present application also provides an air treatment device 1000, which includes an electric heating device 10 based on any one of the above embodiments. The air treatment device 1000 may be a duct air conditioner.

[0093] Since the air handling equipment adopts all the technical solutions of the electric heating device of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment.

[0094] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
