Description

Technical Field

[0001] This disclosure relates to the technical field of household appliances, and in particular to the shell structure of a cooking apparatus using a hot melt adhesive component as a sealing ring. Background Technology

[0002] Home appliances often have elastic sealing rings in their internal structure. These rings isolate air or moisture, protecting the sealed structure and ensuring its proper functioning in various environments. For example, sealing rings are used in washing machine control panels for waterproofing, in appliance compressors to improve airtightness, and in the control panels of kitchen appliances like rice cookers to prevent water vapor from entering. These sealing rings need to have good heat resistance and stability.

[0003] The process of assembling a sealing ring requires precise positioning. Different home appliances require different rubber sealing rings due to their different structures and application scenarios, resulting in low assembly efficiency. Furthermore, a mismatch between the sealing ring and the installation position can affect the sealing effect.

[0004] For example, the rice cooker panel and rice cooker disclosed in prior art document CN201920885216.9 include a panel body, a transparent plastic sheet, and a circuit board. The panel body has a through hole, and the first end face of the transparent plastic sheet protrudes to form a touch screen key. The shape of the touch screen key is the same as the shape of the through hole and is suitable for fitting into the through hole. The first end face of the transparent plastic sheet is attached to the inner wall of the panel body. The circuit board is located below the transparent plastic sheet, and the light source of the circuit board is located directly below the touch screen key on the transparent plastic sheet. A spring is connected to the circuit board, and the two ends of the spring abut against the circuit board and the transparent plastic sheet, respectively. In this design, the circuit board is not sealed with a sealing ring, resulting in poor sealing and inability to prevent dust and moisture from contacting the circuit board. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a steaming apparatus shell structure that uses a hot melt adhesive component to replace the sealing ring, which simplifies assembly and provides better sealing.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A steam cooker housing structure for replacing sealing rings with hot melt adhesive components includes a housing assembly, a control board assembly, and a hot melt adhesive sealing strip.

[0027] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0028] like Figures 1 to 3 As shown, this is a shell structure 10 of a cooking apparatus for a hot melt adhesive component replacing a sealing ring according to an embodiment of this disclosure. It includes a shell assembly 100, a control board assembly 200, and a hot melt adhesive sealing strip 300. The shell assembly 100 includes a cover shell 110 and a panel shell 120. The cover shell 110 has a control circuit receiving groove 1101, and the control board assembly 200 is installed within the control circuit receiving groove 1101.

[0029] The face cover housing 110 has a shaped assembly ring groove 1102. The hot melt adhesive sealing strip 300 is disposed in the shaped assembly ring groove 1102. The shaped assembly ring groove 1102 is sleeved around the control circuit receiving groove 1101. The panel housing 120 covers the face cover housing 110. The hot melt adhesive sealing strip 300 abuts against the face cover housing 110. The hot melt adhesive sealing strip 300 is used to fill the shaped assembly ring groove 1102 after heating. The hot melt adhesive sealing strip 300 is adhered to the shaped assembly ring groove 1102. The side of the hot melt adhesive sealing strip 300 away from the face cover housing 110 elastically abuts against the panel housing 120.

[0030] In this embodiment, the hot melt sealant is heated and then filled into the irregular assembly ring groove 1102 using a hot melt adhesive machine. After the hot melt sealant cures, it forms a hot melt sealant strip 300. The hot melt sealant strip 300 adheres to the inner wall of the ring-shaped assembly groove, making the hot melt sealant strip 300 fit more tightly with the irregular assembly ring groove 1102. The hot melt sealant strip 300 also elastically abuts against the panel housing 120, thus sealing the control circuit receiving groove 1101 in the irregular assembly ring groove 1102.

[0031] The aforementioned hot melt adhesive component replacing the sealing ring in the steaming device housing structure 10 forms a hot melt adhesive sealing strip 300 by filling the irregular assembly ring groove 1102 with hot melt adhesive. This allows the hot melt adhesive sealing strip 300 to adhere to the inner wall of the irregular assembly ring groove 1102, resulting in a tighter fit between the hot melt adhesive sealing strip 300 and the irregular assembly ring groove 1102. This simplifies the assembly process of the hot melt adhesive sealing strip 300, making the assembly and manufacturing of the hot melt adhesive component replacing the sealing ring in the steaming device housing structure 10 more convenient and simple. Through the tight fit between the hot melt adhesive sealing strip 300 and the irregular assembly ring groove 1102, the hot melt adhesive sealing strip 300 elastically abuts against the panel housing 120, resulting in better sealing of the control circuit receiving groove 1101. This prevents dust and moisture from entering the control circuit receiving groove 1101, thereby extending the service life of the control board assembly 200.

[0032] like Figure 2 and Figure 3 As shown, in one embodiment, the side wall of the irregular assembly ring groove 1102 is provided with a first fixing groove 1103, and the hot melt adhesive sealing strip 300 is correspondingly formed with a first fixing block 310, which is embedded in the first fixing groove 1103. In this embodiment, the hot melt sealing adhesive is heated and filled into the irregular assembly ring groove 1102 by a hot melt adhesive machine. The molten hot melt sealing adhesive can flow smoothly into the first fixing groove 1103. When the hot melt sealing adhesive cools and solidifies, the first fixing block 310 is formed. The first fixing block 310 and the first fixing groove 1103 form a tight fit, preventing the hot melt adhesive sealing strip 300 from separating or shifting from the irregular assembly ring groove 1102 due to external forces during use, thereby improving the stability and reliability of the hot melt adhesive sealing strip 300.

[0033] like Figure 2 and Figure 3As shown, in one embodiment, the bottom of the irregular assembly ring groove 1102 is provided with a second fixing groove 1104, and the hot melt adhesive sealing strip 300 is correspondingly formed with a second fixing block 320, which is embedded in the second fixing groove 1104. In this embodiment, when the hot melt sealant is heated and filled into the irregular assembly ring groove 1102 by the hot melt adhesive machine, the molten hot melt sealant flows into the second fixing groove 1104 to form the second fixing block 320. The second fixing block 320 is embedded in the second fixing groove 1104, which enhances the connection between the hot melt sealant strip 300 and the irregular assembly ring groove 1102. The first fixing block 310 and the first fixing groove 1103 cooperate in the side wall direction, and the second fixing block 320 and the second fixing groove 1104 cooperate at the bottom. The synergistic effect in the two directions provides all-round fixation and support between the hot melt sealant strip 300 and the irregular assembly ring groove 1102, which improves the stability and reliability of the hot melt sealant strip 300 and prevents assembly and sealing problems caused by the loosening of the hot melt sealant strip 300.

[0034] like Figure 2 and Figure 3 As shown, in one embodiment, there are multiple first fixing blocks 310, second fixing blocks 320, first fixing grooves 1103 and second fixing grooves 1104. The multiple first fixing blocks 310, multiple second fixing blocks 320, multiple first fixing grooves 1103 and multiple second fixing grooves 1104 are all spaced apart along the extension direction of the irregular assembly ring groove 1102. Each first fixing block 310 is embedded in the corresponding first fixing groove 1103, and each second fixing block 320 is embedded in the corresponding second fixing groove 1104. In this embodiment, the cooperation of multiple first fixing blocks 310 with the first fixing groove 1103 and the second fixing block 320 with the second fixing groove 1104 forms a multi-point connection structure, which makes the hot melt adhesive sealing strip 300 firmly fixed in the irregular assembly ring groove 1102. When the steaming device shell structure 10 of the hot melt adhesive component replacing the sealing ring is subjected to external force, the multi-point connection structure can disperse the stress and avoid stress concentration at a certain point, which would lead to connection failure. This improves the connection stability between the hot melt adhesive sealing strip 300 and the irregular assembly ring groove 1102, and ensures that the hot melt adhesive sealing strip 300 will not loosen or fall off during long-term use.

[0035] like Figure 2As shown, in one embodiment, the control board assembly 200 includes a control circuit board 210, a hot melt adhesive sealing block 220, and a wire 230. The control circuit receiving groove 1101 also has a wire-through hole 1105. The control circuit board 210 is disposed in the control circuit receiving groove 1101. One end of the wire 230 is connected to the control circuit board 210, and the other end of the wire 230 passes through the wire-through hole 1105. The hot melt adhesive sealing block 220 covers the wire 230 and is disposed in the wire-through hole 1105. In this embodiment, the wire 230 is used to transmit current and control signals, the control circuit board 210 is used to process control signals to control the operation of the home appliance, and the hot melt adhesive sealing block 220 seals the wire hole 1105 to prevent external pollutants such as dust, debris, and moisture from entering the device through the wire hole 1105, further improving the sealing performance of the control circuit receiving groove 1101 and avoiding damage such as corrosion and short circuit to the wire 230 and control circuit board 210 caused by pollutants.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the panel housing 120 includes an integrally formed panel portion 121 and a transparent display portion 122, which is correspondingly disposed with the control circuit board 210. In this embodiment, the control circuit board 210 is also provided with a display screen and indicator lights to display the working status of the home appliance. The current working status of the home appliance can be clearly seen through the transparent display portion 122. The integrally formed panel portion 121 and transparent display portion 122 facilitate the assembly of the panel housing 120 with the cover housing 110, and prevent moisture and dust from entering the control circuit receiving groove 1101, thereby protecting the control circuit board 210 and the wires 230.

[0037] like Figure 2 As shown, in one embodiment, the housing assembly 100 further includes a mounting support 130, which is connected to the inner wall of the control circuit receiving groove 1101 of the faceplate housing 110. The control circuit board 210 is mounted on the mounting support 130. In this embodiment, the control circuit board 210 is directly mounted on the mounting support 130. The mounting support 130 serves to support the control circuit board 210 and keep it suspended, thereby improving the heat dissipation performance of the control circuit board 210. The mounting support 130 is integrally connected with the faceplate housing 110, which also improves the mechanical strength of the faceplate housing 110.

[0038] like Figure 2As shown, in one embodiment, the housing assembly 100 further includes a fastener 140, which is disposed in the control circuit receiving groove 1101 and fastened to the control circuit board 210. In this embodiment, the fastener 140 is connected to the control circuit board 210 by a fastening method, so that the control circuit board 210 is fixed in the control circuit receiving groove 1101. By fastening, the control circuit board 210 can be quickly disassembled and replaced, thereby accelerating the assembly efficiency of the cooking device housing structure 10 of the hot melt adhesive replacement sealing ring.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the cover housing 110 has a positioning groove 1106, and the inner side of the panel housing 120 has a positioning block 123 protruding therefrom, the positioning block 123 being installed in the positioning groove 1106. In this embodiment, by fitting the positioning block 123 into the positioning groove 1106, the installation positions of the cover housing 110 and the panel housing 120 are fixed, thereby improving the assembly speed of the cover housing 110 and the panel housing 120.

[0040] like Figure 1 and Figure 2 As shown, in one embodiment, the steaming device housing structure 10 for the hot melt adhesive component replacing the sealing ring further includes a venting component 400. The housing 110 has a first receiving channel 1107, and the panel housing 120 has a second receiving channel 1201 communicating with the first receiving channel 1107. The venting component 400 is installed in the first receiving channel 1107 and passes through the second receiving channel. The venting component 400 has a vent hole 401, which is located on the side of the venting component 400 away from the control circuit receiving groove 1101. In this embodiment, when the appliance is working, high-temperature water vapor will pass through the vent hole 401. The control circuit receiving groove 1101 needs to reduce the entry of water vapor. The vent hole 401 is located on the side of the venting component 400 away from the control circuit receiving groove 1101, which prevents high-temperature water vapor from entering the control circuit receiving groove 1101, thereby improving the service life of the control board assembly 200 in the control circuit receiving groove 1101.

[0041] Compared with the prior art, this disclosure has at least the following advantages:

[0042] The aforementioned hot melt adhesive component replacing the sealing ring in the steaming device housing structure 10 forms a hot melt adhesive sealing strip 300 by filling the irregular assembly ring groove 1102 with hot melt adhesive. This allows the hot melt adhesive sealing strip 300 to adhere to the inner wall of the irregular assembly ring groove 1102, resulting in a tighter fit between the hot melt adhesive sealing strip 300 and the irregular assembly ring groove 1102. This simplifies the assembly process of the hot melt adhesive sealing strip 300, making the assembly and manufacturing of the hot melt adhesive component replacing the sealing ring in the steaming device housing structure 10 more convenient and simple. Through the tight fit between the hot melt adhesive sealing strip 300 and the irregular assembly ring groove 1102, the hot melt adhesive sealing strip 300 elastically abuts against the panel housing 120, resulting in better sealing of the control circuit receiving groove 1101. This prevents dust and moisture from entering the control circuit receiving groove 1101, thereby extending the service life of the control board assembly 200.
