Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to a gas stove. Background Technology

[0002] Currently, most gas equipment uses an external drive mounted on a Z-shaped electrical control mounting plate to drive and control the exhaust fan and the blower motor.

[0003] Although the drive solution using a Z-type electronic control mounting plate can save on the drive cost of gas equipment, the Z-type electronic control mounting plate usually needs to be fixed to the volute, and the volute is a curved surface, which can easily affect the stability of the installation and fixation. Utility Model Content

[0004] In view of this, the present application provides a gas furnace that can improve the stability of the mounting plate for installing an external drive.

[0005] The gas furnace of this application includes: a shell; a fan wheel disposed inside the shell, the fan wheel including a volute and two side plates, the two side plates being disposed on both sides of the volute; and a mounting assembly including a mounting bracket and a mounting plate, one end of the mounting bracket being connected to the side plate and the other end being connected to the mounting plate.

[0006] Furthermore, the mounting bracket includes multiple brackets, and the mounting assembly further includes a limiting bracket, which connects any two of the mounting brackets and is connected to the mounting plate.

[0007] Furthermore, the mounting bracket includes a first mounting bracket, a second mounting bracket, a third mounting bracket, and a fourth mounting bracket, and the limiting bracket includes a first limiting bracket and a second limiting bracket. The first limiting bracket connects the first mounting bracket and the second mounting bracket, and the second limiting bracket connects the third mounting bracket and the fourth mounting bracket.

[0008] Furthermore, the first limiting bracket includes a mounting part and a limiting part, the limiting part includes a limiting groove, and a first limiting plate extends from the mounting plate, the first limiting plate being disposed within the limiting groove.

[0009] Furthermore, a second limiting plate extends from the mounting plate, and the second limiting plate abuts against the second limiting bracket.

[0010] Furthermore, the mounting plate is provided with a plurality of mounting screw holes, and the mounting bracket is provided with a plurality of assembly screw holes that match the mounting screw holes.

[0011] Furthermore, the mounting plate is provided with multiple mounting screw holes, and the limiting bracket is provided with multiple assembly screw holes that match the mounting screw holes.

[0012] Furthermore, the mounting plate is provided with a plurality of mounting screw holes, and the limiting part is provided with a plurality of assembly screw holes that match the mounting screw holes.

[0013] Furthermore, the mounting bracket and the side plate are screwed together.

[0014] Furthermore, the mounting plate includes a printed circuit board.

[0015] The gas furnace according to this application includes a shell, a blower, and a mounting assembly. The blower is located inside the shell and includes a volute and two side plates. The two side plates are located on both sides of the volute, forming a spiral structure to facilitate the smooth entry of air into the combustion chamber inside the gas furnace shell, ensuring the combustion efficiency of the gas furnace. The mounting assembly includes a mounting bracket and a mounting plate. One end of the mounting bracket is connected to the side plate, and the other end is connected to the mounting plate to provide support for the mounting plate. The mounting plate can be an external drive plate for the gas furnace or an external drive for mounting the gas furnace. Since the side plates do not contain curved surfaces, the fixed connection between the mounting bracket and the side plates to provide support for the mounting plate ensures the structural stability of the mounting plate, avoids the risk of slippage and foreign objects falling into the blower's air duct during installation, and improves the safety and service life of the gas furnace.

[0016] Furthermore, since the mounting plate does not require an additional folded edge for mounting and fixing to the internal components of the gas furnace, it can save production materials and reduce production costs, further enabling the miniaturization of the gas furnace.

[0017] Additional aspects and advantages of embodiments of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of embodiments of this application. Attached Figure Description

[0023] Figure 5 This is a schematic diagram of the structure of the limiting part, the mounting part and the limiting groove of the limiting bracket according to certain embodiments of this application; Detailed Implementation

[0024] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0025] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one feature. In the description of this application, "multiple" means at least two, such as two or three, unless otherwise explicitly specified.

[0027] In the gas furnace industry, exhaust fans and blower motors directly affect the furnace's efficiency, exhaust performance, and energy consumption. Traditional gas furnaces mostly use built-in drives to operate the exhaust fans and blower motors; for example, a built-in controller controls the motor's operation to drive the fan impeller and generate airflow. Because built-in drives typically require higher precision and more complex designs, the production cost of gas furnaces is higher.

[0028] In order to reduce the production cost of gas furnaces and improve the performance of exhaust fans (under the built-in drive scheme, it is difficult to select the type of motor for the exhaust fan, and the exhaust fan is difficult to meet the high static pressure), most gas furnaces currently use an external drive scheme to drive the exhaust fan and the blower motor.

[0029] For related technologies, please refer to Figure 1Typically, an electrical control mounting box 101 (including a printed circuit board (PCB) for driving the exhaust fan and the blower motor) is provided for the gas appliance 100. The electrical control mounting box 101 is mounted on a Z-shaped electrical control mounting plate 102, which needs to be fixed to the volute 103 of the gas appliance 100 with screws. Since the screws are fixed to the volute 103, which is a curved surface, the screws are prone to slippage. When tightening the screws, the iron filings generated by the screws can easily fall into the air duct of the gas appliance 100, affecting the safety and service life of the gas appliance 100. In addition, since the Z-shaped electrical control mounting plate 102 is fixed to the volute 103 by setting a folded edge 104, the production cost is high. The Z-shaped electrical control mounting plate 102 also occupies a large space inside the gas appliance 100, making it difficult to achieve miniaturization of the gas appliance 100.

[0030] The gas furnace provided in this application will be described in detail below.

[0031] Please see Figures 2 to 4 This application provides a gas stove 200, which includes:

[0032] case;

[0033] The impeller 20 is located inside the housing. The impeller 20 includes a volute 21 and two side plates 22, which are located on both sides of the volute.

[0034] Mounting component 30 includes mounting bracket 31 and mounting plate 32. One end of mounting bracket 31 is connected to side plate 22, and the other end is connected to mounting plate 32.

[0035] The shell can be the external frame of the gas furnace 200, used to protect the internal components of the gas furnace 200 (such as the impeller 20, burner, etc.). The shell can be made of high-temperature resistant and corrosion-resistant materials to cope with the working conditions of the gas furnace 200 in high-temperature and complex environments.

[0036] The impeller 20 can be used to deliver air (oxygen) into the gas furnace 200 to provide the necessary oxygen for gas combustion and improve combustion efficiency.

[0037] The mounting plate 32 may include a PCB board, for example, the mounting plate 32 is a PCB board; or, the PCB board and the mounting plate 32 are fixedly connected to each other to be mounted on the mounting plate 32. Based on the PCB board, the driving and control of various components (e.g., fans, etc.) inside the housing of the gas furnace 200 can be realized.

[0038] For example, please refer to Figure 4The mounting plate 32 has multiple mounting screw holes 321, and the mounting bracket 31 has multiple assembly screw holes that match the mounting screw holes. By sequentially locking the mounting screw holes and assembly screw holes with bolts, a fixed connection can be achieved between the mounting plate 32 and the mounting bracket 31. Please refer again. Figure 1 In existing solutions that use a Z-type electrical control mounting plate 101 to externally drive the gas appliance 100, during installation, the installer's line of sight is usually overhead. The screws at the connection between the Z-type electrical control mounting plate 102 and the volute 103 of the gas appliance 100 are easily obstructed by the Z-type electrical control mounting plate 102, making installation and replacement of the Z-type electrical control mounting plate 102 difficult. However, the mounting screw holes in this application are located on the front of the mounting plate 32, avoiding the problem of obstructed mounting screw holes and thus improving the convenience of installation and after-sales repair.

[0039] This is understandable; please refer to [link / reference]. Figure 1 and Figure 4 Compared to the Z-shaped structure of the existing Z-shaped electrical control mounting box, the mounting plate 32 of this application can be set to a flat state, which improves the utilization rate of sheet metal and makes it more convenient to install electronic components and transport the entire electrical control box.

[0040] The mounting bracket 31 and the side plate 22 are screwed together to achieve a fixed connection between them. Since the side plate 22 is not curved, the connection stability of the mounting bracket 31 can also be improved.

[0041] Specifically, please refer to Figure 2 and Figure 3The gas furnace 200 includes a shell, a blower 20, and a mounting assembly 30. The blower 20 is located inside the shell and includes a volute 21 and two side plates 22. The two side plates 22 are located on both sides of the volute 21. The volute 21 guides air into the blower 20, and the two side plates 22 support and protect the volute 21 (where the blades of the blower 20 can be housed) and the blades of the blower 20, preventing damage or deformation and improving the stability of the blower 20. The two side plates 22, located on both sides of the volute 21, form a spiral structure, which helps convert the kinetic energy of the airflow into pressure, facilitating the smooth entry of air into the combustion chamber inside the gas furnace 200 shell. The mounting assembly 30 includes a mounting bracket 31 and a mounting plate 32. One end of the mounting bracket 31 is fixedly connected to the side plate 22, and the other end is fixedly connected to the mounting plate 32, providing support for the mounting plate 32 and preventing the mounting plate 32 from falling off when internal components of the gas furnace 200 are operating (e.g., the impeller 20 rotates). By fixing the electrical control box (i.e., the PCB board) onto the mounting plate 32, the installation and setup of the external drive for the gas furnace 200 can be completed. Since the side plate 22 does not contain a curved surface, the fixed connection between the mounting bracket 31 and the side plate 22 to provide support for the mounting plate 32 ensures the structural stability of the mounting plate 32, avoiding the risk of slippage and foreign objects falling into the air duct of the impeller 20 during installation, thus improving the safety and service life of the gas furnace 200.

[0042] Thus, the gas furnace 200 includes a shell, a blower 20, and a mounting assembly 30. The blower 20 is located inside the shell and includes a volute 21 and two side plates 22. The two side plates 22 are located on both sides of the volute 21, forming a spiral structure to facilitate the smooth entry of air into the combustion chamber inside the gas furnace 200 shell, ensuring the combustion efficiency of the gas furnace 200. The mounting assembly 30 includes a mounting bracket 31 and a mounting plate 32. One end of the mounting bracket 31 is connected to the side plate 22, and the other end is connected to the mounting plate 32 to provide support for the mounting plate 32. The mounting plate 32 can be an external drive plate of the gas furnace 200 or an external drive for mounting the gas furnace 200. Since the side plate 22 does not contain a curved surface, the fixed connection between the mounting bracket 31 and the side plate 22 to provide support for the mounting plate 32 ensures the structural stability of the mounting plate 32, avoids the risk of slippage and foreign objects falling into the air duct of the blower 20 during installation, and improves the safety and service life of the gas furnace 200.

[0043] Furthermore, since the mounting plate 32 does not require an additional folded edge to install and fix the components inside the gas furnace 200, it can save production materials and production costs, and further realize the miniaturization of the gas furnace 200.

[0044] Please see Figure 3Furthermore, the mounting bracket 31 includes multiple brackets, and the mounting assembly 30 also includes a limiting bracket 33, which connects any two mounting brackets 31 and connects to the mounting plate 32.

[0045] The limiting bracket can keep the phase position between any two mounting brackets 31 stable, ensuring that the position of the mounting brackets 31 will not move during the operation of the gas furnace 200, and further improving the stability of the mounting assembly 30.

[0046] Specifically, please refer to Figure 4 Taking a mounting bracket 31 comprising four components—a first mounting bracket 311, a second mounting bracket 312, a third mounting bracket 313, and a fourth mounting bracket 314—as an example, a limiting bracket 33 can connect any two mounting brackets 31. For instance, taking two limiting brackets 33, connecting the first mounting bracket 311, the second mounting bracket 312, the third mounting bracket 313, and the fourth mounting bracket 314 respectively, the two limiting brackets 33 connect to the mounting plate 32 to provide support for the mounting plate 32, further improving the stability of the mounting assembly 30. For another example, please refer to... Figure 5 Taking the limiting bracket 33 as an example, which includes two brackets, respectively connecting the first mounting bracket 311 and the third mounting bracket 313, the second mounting bracket 312 and the fourth mounting bracket 314 (i.e. the two limiting brackets 33 interfere with each other), the two limiting brackets 33 are connected to the mounting plate 32 to provide support for the mounting plate 32 and further improve the stability of the mounting assembly 30.

[0047] Please see Figure 3 Furthermore, the mounting bracket 31 includes a first mounting bracket 311, a second mounting bracket 312, a third mounting bracket 313, and a fourth mounting bracket 314, and the limiting bracket 33 includes a first limiting bracket 331 and a second limiting bracket 332. The first limiting bracket 331 connects the first mounting bracket 311 and the second mounting bracket 312, and the second limiting bracket 332 connects the third mounting bracket 313 and the fourth mounting bracket 314.

[0048] Specifically, the limiting bracket 33 includes a first limiting bracket 331 and a second limiting bracket 332. The first limiting bracket 331 connects the first mounting bracket 311 and the second mounting bracket 312 to limit the relative position between the first mounting bracket 311 and the second mounting bracket 312, thereby improving the stability of the first mounting bracket 311 and the second mounting bracket 312. The second limiting bracket 332 connects the third mounting bracket 313 and the fourth mounting bracket 314 to limit the relative position between the third mounting bracket 313 and the fourth mounting bracket 314, thereby improving the stability of the third mounting bracket 313 and the fourth mounting bracket 314, and further improving the reliability of the mounting plate 32.

[0049] It is understood that the limiting bracket 33 may also include four brackets. For example, taking the limiting bracket 33 as including a first limiting bracket 331, a second limiting bracket 332, a third limiting bracket, and a fourth limiting bracket as an example, the first limiting bracket 331 is connected to the first mounting bracket 311 and the second mounting bracket 312, the second limiting bracket 332 is connected to the third mounting bracket 313 and the fourth mounting bracket 314, the third limiting bracket is connected to the first mounting bracket 311 and the third mounting bracket 313, and the fourth limiting bracket is connected to the second mounting bracket 312 and the fourth mounting bracket 314; or, the third limiting bracket is connected to the second mounting bracket 312 and the third mounting bracket 313, and the fourth limiting bracket is connected to the first mounting bracket 311 and the fourth mounting bracket 314, etc. This application does not limit this and will not list them all here.

[0050] Please see Figure 3 and Figure 5 Furthermore, the first limiting bracket 331 includes a mounting part 3311 and a limiting part 3312. The limiting part 3312 includes a limiting groove 3313. A first limiting plate 322 extends from the mounting plate 32 and is disposed in the limiting groove 3313.

[0051] The mounting plate 32 extends to provide a second limiting plate 323, which abuts against the second limiting bracket 332.

[0052] Specifically, in existing Z-type electrical control mounting plates, the lack of positioning between the mounting plate and the volute often requires workers to repeatedly adjust and confirm the mounting position, leading to installation difficulties and low efficiency. Please refer to [link / reference]. Figure 3 and Figure 5 This application provides two mounting portions 3311 and a limiting portion 3312 for the limiting bracket 33. The limiting portion 3312 is located between the two mounting portions 3311 and has a limiting groove 3313. A first limiting plate 322 (i.e., a folded edge) extends from the mounting plate 32 and is perpendicular to the mounting plate 32. The first limiting plate 322 can improve the strength of the mounting plate 32. During installation, the first limiting plate 322 is placed in the limiting groove 3313 (the limiting groove 3313 can restrict the movement of the first limiting plate 322 in the horizontal direction (i.e., the front-back direction and the left-right direction)) to complete the positioning of the mounting plate 32. A second limiting plate 323 extends from the mounting plate 32 and abuts against the second limiting bracket 332 to complete the positioning and limiting of the mounting plate 32 in the height direction, thereby improving the installation efficiency of the mounting plate 32.

[0053] Please see Figure 4 and Figure 5Furthermore, the mounting plate 32 is provided with multiple mounting screw holes 321, and the limiting bracket 33 is provided with multiple assembly screw holes 333 that match the mounting screw holes 321.

[0054] Furthermore, the mounting plate 32 is provided with a plurality of mounting screw holes 321, and the limiting part 3312 is provided with a plurality of assembly screw holes 333 that match the mounting screw holes 321.

[0055] Specifically, taking a limiting bracket comprising two mounting portions 3311 and one limiting portion 3312, with the limiting portion 3312 located between the two mounting portions 3311 as an example, the mounting plate 32 is provided with multiple mounting screw holes 321, and the mounting portions 3311 and / or the limiting portion 3312 of the limiting bracket are provided with multiple assembly screw holes 333 that match the mounting screw holes 321. Through the engagement of bolts, mounting screw holes 321, and assembly screw holes 333, a fixed connection between the mounting plate 32 and the limiting bracket can be achieved. For example, taking a limiting bracket where both mounting portions 3311 are provided with multiple assembly screw holes 333 that match the mounting screw holes 321 as an example, the fixed connection between the mounting plate 32 and the limiting bracket is achieved by sequentially screwing bolts into the mounting screw holes 321 and the assembly screw holes 333. For example, taking the limiting part 3312 of the limiting bracket as having an assembly screw hole 333 that matches the mounting screw hole 321, the mounting plate 32 and the limiting bracket are fixedly connected by bolts sequentially engaging with the mounting screw hole 321 and the assembly screw hole 333, and the first limiting plate 322 is further fixed in the limiting groove 3313 to achieve positioning.
