Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a baffle box assembly and a water heater. Background Technology

[0002] Water heaters, as a type of household hot water device, are mainly used in kitchens or bathrooms to provide instant hot water, thus solving the problem of cold water in scenarios such as washing dishes, vegetables, and hands in winter. Based on the different heating methods, water heaters are mainly divided into two types: storage water heaters and instantaneous water heaters.

[0003] Existing water heaters have a material retainer box on the outer casing for housing the control components. After installing the retainer box onto the water heater casing, a gap inevitably exists between the two, posing a risk of foam material overflow. Currently, the common practice is to attach a sponge strip to the gap. However, using sponge strips to seal the gap is not only costly and cumbersome, but also ineffective at preventing overflow, especially as the sponge strips age over time, further reducing their effectiveness. Utility Model Content

[0039] like Figures 1 to 4 As shown, this utility model discloses a baffle box assembly 10, which is used in a water heater and for installing control components and implementing baffle functionality. Specifically, as... Figures 1 to 11 As shown, the baffle box assembly 10 includes a housing 100 and a baffle box structure 200. The housing 100 is the main external structure of the water heater. The housing 100 includes an inner protrusion 101 and a recessed inner wall surface 102 formed outside the inner protrusion 101. A mounting hole 103 is provided through the inner protrusion 101. It should be noted that the recess of the recessed inner wall surface 102 is relative to the inner protrusion of the inner protrusion 101. That is, the inner wall surface corresponding to the inner protrusion 101 is closer to the center line of the housing 100 than the recessed inner wall surface 102. The baffle box structure 200 is a structure for installing control components in a water heater. The baffle box structure 200 includes a box body 201 and a ring edge 202. A chamber for installing control components is formed inside the box body 201. The ring edge 202 is located at the open end of the box body 201 and extends outward along the circumference of the box body 201. A recessed structure 203 and a ring groove structure 204 are provided on the ring edge 202. The recessed structure 203 is arranged along the circumference of the opening of the box body 201, and the ring groove structure 204 is arranged around the circumference of the recessed structure 203.

[0040] When assembling the baffle box assembly 10, the baffle box structure 200 is first installed inside the outer shell 100, with the opening of the box body 201 facing the mounting hole 103 to achieve communication. The inner protrusion 101 is embedded in the recessed structure 203, and a first baffle structure 11 is formed at the bend edge where the inner protrusion 101 and the recessed structure 203 meet. The ring edge 202 abuts against the inner wall surface 102 of the recess. A second baffle structure 12 is formed between the concave surface of the annular groove structure 204 and the inner wall surface 102 of the recess. The first baffle structure 11 can be a bend edge, such as a right-angle bend edge, or a material-accommodating space formed at the edge. The second baffle structure 12 is a material-accommodating space formed between the concave surface of the annular groove structure 204 and the inner wall surface 102 of the recess.

[0041] It should be noted that when filling the foaming space of the water heater with foaming material, the small gap formed at the joint between the baffle box structure 200 and the outer shell 100 can easily cause foaming material overflow. In the embodiments of this application, both the first baffle structure 11 and the second baffle structure 12 have a blocking effect on the foaming material filled into the water heater. That is to say, at least two baffle structures can be formed by the second baffle structure 12 and the first baffle structure 11. The foaming material can only overflow after passing through the second baffle structure 12 and the first baffle structure 11, thus reducing the probability of overflow and improving product quality. Furthermore, by designing the baffle box structure 200 with a large-sized ring edge 202, the ring edge 202 increases the contact area between the baffle box structure 200 and the outer shell 100. This not only provides sufficient space for designing the recessed structure 203 and the annular groove structure 204, but also extends the length of the gap. Even if a small amount of foam material enters this gap, it is less likely to overflow outside the outer shell 100, thus extending the flow path of the foam material. This design also helps reduce the probability of overflow. In addition, the setting of at least two baffle structures eliminates the need for sealing structures such as sponge strips between the baffle box structure 200 and the outer shell 100. The omission of sealing structures helps reduce the cost of preventing overflow and also improves assembly efficiency and reduces assembly difficulty.

[0042] Regarding the structure of the housing 100, in some embodiments, such as Figure 6 As shown, the outer shell 100 is a cylindrical structure open at both ends. Optionally, the outer shell 100 is a shell structure with an elliptical cross-section. Of course, in other embodiments, the outer shell 100 can also be a shell structure with a circular, square, or other cross-sections, depending on the requirements.

[0043] In some embodiments, the outer shell 100 is an integrally formed sheet metal part, and the inner protrusion 101 and the mounting hole 103 are integrally formed during stamping, which is simple and efficient in manufacturing.

[0044] In some embodiments, the mounting hole 103 is a rectangular hole, and the outer contour of the inner protrusion 101 is also generally rectangular. Further, rounded corners or chamfers may be provided at the corners of the outer contour of the inner protrusion 101. Of course, in other embodiments, the shape of the mounting hole 103 can be flexibly set to other shapes as needed, preferably adapted to the opening shape of the box body 201; the shape of the outer contour of the inner protrusion 101 can also be flexibly set to other shapes as needed, preferably adapted to the shape of the outer contour of the ring edge 202.

[0045] Regarding the structure of the baffle box 200, in some embodiments, such as Figure 8 and Figure 9 As shown, the baffle box structure 200 is an integrally molded injection part, and the recessed structure 203 and the annular groove structure 204 are also integrally molded during injection molding, which is simple and efficient in manufacturing.

[0046] In some embodiments, the outer contour of the box body 201 in a section perpendicular to its protruding direction is approximately rectangular, the opening of the box body 201 is rectangular, and the outer contour of the ring edge 202 is also approximately rectangular. Further, rounded corners or chamfers are provided at the corners of the outer contour of the ring edge 202. Of course, in other embodiments, the shape of the opening of the box body 201 can be flexibly set to other shapes as needed, preferably adapted to the shape of the mounting hole 103; the shape of the outer contour of the ring edge 202 can also be flexibly set to other shapes as needed, preferably adapted to the shape of the outer contour of the inner protrusion 101.

[0047] To improve the anti-overflow effect, at least two annular groove structures 204 are provided, and the at least two annular groove structures 204 are spaced apart in the extending direction of the annular edge 202. This arrangement forms multiple second baffle structures 12, ensuring that the foaming material only reaches the first baffle structure 11 after passing through multiple second baffle structures 12, resulting in better material blocking and reducing the likelihood of overflow. In a specific embodiment, referring to… Figure 9 As shown, there are two annular groove structures 204, which form two second baffle structures 12. The two second baffle structures 12 and one first baffle structure 11 form a triple baffle structure. Optionally, the cross-section of the annular groove structure 204 is formed as a semi-circle, a semi-ellipse, or a triangle, etc.

[0048] In some embodiments, a raised rib structure 205 is provided on the ring edge 202, and the raised rib structure 205 and the ring groove structure 204 are arranged opposite each other in the thickness direction of the ring edge 202. That is, the ring groove structure 204 is formed at the same time as the raised rib structure 205, so that the thickness of the ring edge 202 remains basically unchanged, which is beneficial to achieving a thinner and lighter baffle box structure 200, and also more aesthetically pleasing.

[0049] Continue to refer to Figure 8As shown, to improve the structural strength of the baffle box structure 200, a reinforcing rib structure 209 is provided on the outer wall surface of the box body 201. The reinforcing rib structure 209 enhances the structural strength of the box body 201, preventing deformation or damage to the baffle box structure 200. In some embodiments, the reinforcing rib structure 209 includes a first reinforcing rib 2091 and a second reinforcing rib 2092. The first reinforcing rib 2091 extends along the length direction of the box body 201, and the second reinforcing rib 2092 extends along the width direction of the box body 201. Furthermore, multiple first reinforcing ribs 2091 and multiple second reinforcing ribs 2092 are provided. Multiple first reinforcing ribs 2091 are spaced apart along the width direction of the box body 201, and multiple second reinforcing ribs 2092 are spaced apart along the length direction of the box body 201. The multiple first reinforcing ribs 2091 and multiple second reinforcing ribs 2092 are arranged in a mesh pattern, which further enhances the strength of the baffle box structure 200.

[0050] To facilitate the extension of the control component's wires into the water heater's interior, the main body 201 is provided with a wire passage hole. The wires of the control components located inside the main body 201 can extend through the wire passage hole to the outside of the baffle box structure 200, so as to facilitate electrical connection with the heating components, measuring components, etc., located inside the water heater's inner tank.

[0051] Continue to refer to Figure 8 As shown, the baffle box structure 200 also includes a tubular portion 210, which is located on one side of the ring edge 202 and is arranged side by side with the box body 201. One end of the tubular portion 210 communicates with the wire passage hole, and the other end forms a wire outlet. The tubular portion 210 is designed to protect and waterproof the wire harness, preventing damage or short circuits. Optionally, the tubular portion 210 is approximately L-shaped, which allows the wire outlet to face the inner liner, facilitating wire routing and connection.

[0052] To achieve rapid assembly of the outer shell 100 and the retaining box structure 200, the outer shell 100 and the retaining box structure 200 employ a sliding snap-fit ​​method for quick engagement or disassembly. Specifically, one of the outer shell 100 and the ring edge 202 is provided with a first snap-fit ​​hole structure 104, and the other is provided with a first snap-fit ​​structure 206. The first snap-fit ​​structure 206 engages with the first snap-fit ​​hole structure 104 by translation. When assembling the outer shell 100 and the retaining box structure 200, due to the small size of the retaining box structure 200, it is generally chosen to move the retaining box structure 200. The assembly process is as follows: First, the retaining box structure 200 is moved so that the first snap-fit ​​structure 206 enters the first snap-fit ​​hole structure 104; then, the retaining box structure 200 is moved further until it engages with the edge of the solid structure forming the first snap-fit ​​hole structure 104, thus completing the engagement.

[0053] In some embodiments, such as Figure 7 and Figure 9 As shown, the first snap-fit ​​structure 206 is provided on the baffle box structure 200, and the first snap-hole structure 104 is provided on the outer shell 100.

[0054] Optionally, the first snap-fit ​​structure 206 is an L-shaped structure; the first snap-hole structure 104 is an elongated hole. Optionally, the first snap-hole structure 104 includes a wide section and a narrow section, the width of the wide section is greater than the width of the narrow section, and the first snap-fit ​​structure 206 enters from the wide section and eventually moves to the narrow section.

[0055] To improve assembly stability, multiple first snap-fit ​​structures 206 and first snap-hole structures 104 are provided, and they are arranged in a one-to-one correspondence. Optionally, multiple first snap-fit ​​structures 206 are provided on the ring edge 202 and located on both sides of the opening of the box body 201. In a specific embodiment, referring to... Figure 7 and Figure 9 As shown, there are four first snap-fit ​​structures 206, and correspondingly, there are four first snap-hole structures 104. The four first snap-fit ​​structures 206 are arranged in two rows and two columns, with two first snap-fit ​​structures 206 located on one side of the opening of the box body 201 and the remaining two first snap-fit ​​structures 206 located on the other side of the opening of the box body 201. The four first snap-hole structures 104 are also arranged in two rows and two columns, with two first snap-hole structures 104 located on one side of the mounting hole 103 and the remaining two first snap-hole structures 104 located on the other side of the mounting hole 103.

After the first buckle structure 206 is snapped onto the edge of the solid structure forming the first buckle hole structure 104, the first limiting protrusion 207 can be inserted into the first limiting hole 106 to achieve the limiting between the two.

[0057] In some embodiments, a first limiting hole 106 is provided on the outer shell 100, and a first limiting protrusion 207 is provided on the annular edge 202. In the moving direction of the baffle box structure 200, the first limiting hole 106 is located downstream of the first snap-fit ​​structure 104. Thus, after the first snap-fit ​​structure 206 is snapped onto the edge of the solid structure forming the first snap-fit ​​structure 104, the first limiting protrusion 207 can be directly pressed into the first limiting hole 106 by pressing the baffle box structure 200.

[0058] In order to improve the limiting effect, a plurality of first limiting holes 106 and a plurality of first limiting protrusions 207 may be provided, and are arranged in one-to-one correspondence. In a specific embodiment, two first limiting holes 106 are provided, and correspondingly, two first limiting protrusions 207 are also provided. Optionally, the first limiting hole 106 is a rectangular hole, and the first limiting protrusion 207 is a rectangular block.

[0059] With further reference to Figure 2 , Figure 4 , as shown in the figures, the material blocking box assembly 10 further comprises a control panel 300, the control panel 300 is arranged on the outer side of the outer housing 100 and detachably connected to the material blocking box structure 200. The control panel 300 can close the opening of the box main body 201 and the mounting hole 103, and the control panel 300 can close the cavity formed by the material blocking box structure 200 for mounting control components, so as to achieve dust prevention for the control components.

[0060] With further reference to Figure 10 and Figure 11 , as shown in the figures, the control panel 300 comprises a cover body 310, a circuit board 320 and a diaphragm 330. For mounting the circuit board 320, a first annular rib is arranged on the back surface of the cover body 310, the first annular rib encloses to form a first mounting cavity, and the circuit board 320 is detachably mounted in the first mounting cavity. Optionally, a first limiting buckle is arranged at the edge of the first mounting cavity, and the first limiting buckle presses against the edge of the circuit board 320 to realize limiting of the circuit board 320; a first screw hole is further arranged at the edge of the first mounting cavity, and a screw passes through the circuit board 320 and is fixed in the first screw hole. For mounting the diaphragm 330, a diaphragm groove is arranged on the front surface of the cover body 310, and the diaphragm 330 is adhered in the diaphragm groove.

[0061] A second annular rib is further arranged on the back surface of the cover body 310, the second annular rib encloses to form a second mounting cavity, and the second mounting cavity is used for mounting a WIFI box. Optionally, the first annular rib and the second annular rib share a part of the rib to form a "day"-shaped structure. Further, a second limiting buckle for clamping the WIFI box is further arranged on the back surface of the cover body 310, and the second limiting buckle presses against the edge of the WIFI box to realize limiting of the WIFI box; a second screw hole is further arranged in the first mounting cavity, and a screw passes through the WIFI box and is fixed in the second screw hole.

[0062] In order to improve the structural compactness after assembling the outer housing 100 and the control panel 300, in some embodiments, a groove portion 108 is arranged on the outer housing 100, the groove portion 108 and the inner convex portion 101 are arranged oppositely in the thickness direction of the outer housing 100, and the control panel 300 is embedded in the groove portion 108. It should be noted that the outer contour shape of the groove portion 108 is adapted to the outer contour shape of the cover body 310.

[0063] To enable rapid assembly of the housing 100 and the control panel 300, the housing 100 and the control panel 300 employ a sliding snap-fit ​​mechanism for quick engagement or disassembly. Specifically, as follows... Figure 7 and Figure 11 As shown, one of the covers 310 of the outer casing 100 and the control panel 300 has a second snap-fit ​​structure 105, and the other has a second snap-fit ​​structure 301. The second snap-fit ​​structure 301 is engaged with the second snap-fit ​​structure 105 by translation. When assembling the outer casing 100 and the control panel 300, since the control panel 300 is relatively small, it is generally moved. The assembly process is as follows: First, the control panel 300 is moved so that the second snap-fit ​​structure 301 enters the second snap-fit ​​structure 105; then, the control panel 300 is moved further until it is engaged with the edge of the solid structure forming the second snap-fit ​​structure 105, thus completing the engagement.

[0064] In some embodiments, continue to refer to Figure 7 and Figure 11 As shown, the second snap-fit ​​structure 301 is provided on the cover 310 of the control panel 300, and the second snap-hole structure 105 is provided on the outer shell 100.

[0065] Optionally, the second snap-fit ​​structure 301 is an L-shaped structure; the second snap-hole structure 105 is an elongated hole. Optionally, the second snap-hole structure 105 includes a wide section and a narrow section, the width of the wide section is greater than the width of the narrow section, and the second snap-fit ​​structure 301 enters from the wide section and eventually moves to the narrow section.

[0066] To improve assembly stability, multiple second snap-fit ​​structures 301 and multiple second snap-hole structures 105 are provided, and they are arranged in a one-to-one correspondence. Optionally, multiple second snap-fit ​​structures 301 are provided on the cover 310 and located on both sides of the circuit board 320. In a specific embodiment, there are eight second snap-fit ​​structures 301, and the eight second snap-fit ​​structures 301 are arranged in four rows and two columns, with four second snap-fit ​​structures 301 located on one side of the circuit board 320 and the remaining four second snap-fit ​​structures 301 located on the other side of the circuit board 320; correspondingly, there are eight second snap-hole structures 105, and the eight second snap-hole structures 105 are also arranged in four rows and two columns, with four second snap-hole structures 105 located on one side of the mounting hole 103 and the remaining four second snap-hole structures 105 located on the other side of the mounting hole 103.

[0067] Continue to refer to Figure 7 and Figure 11As shown, in order to prevent the control panel 300 from accidentally detaching from the housing 100, one of the housing 100 and the cover 310 is provided with a second limiting hole 107 and the other is provided with a second limiting protrusion 302. After the second snap-fit ​​structure 301 is snapped onto the edge of the solid structure forming the second snap hole structure 105, the second limiting protrusion 302 can be inserted into the second limiting hole 107 to achieve the limiting between the two.

[0068] In some embodiments, a second limiting hole 107 is provided on the outer casing 100, and a second limiting protrusion 302 is provided on the cover 310. In the moving direction of the control panel 300, the second limiting hole 107 is located downstream of the second latching structure 105. This allows the second limiting protrusion 302 to be pressed into the second limiting hole 107 directly by pressing the control panel 300 after the second latching structure 301 is engaged at the edge of the solid structure forming the second latching structure 105. Further, referring to... Figure 7 As shown, the first limiting hole 106 and the second limiting hole 107 are located on the same side of the mounting hole 103.

[0069] To improve the limiting effect, multiple second limiting holes 107 and multiple second limiting protrusions 302 can be provided, and they can be arranged in a one-to-one correspondence. In a specific embodiment, there are two second limiting holes 107, and correspondingly, there are also two second limiting protrusions 302. Optionally, the second limiting hole 107 is a rectangular hole, and the second limiting protrusion 302 is a U-shaped rib.

[0070] Optionally, a handle groove 303 is provided at one end of the cover 310 of the control panel 300 to facilitate the disassembly of the control panel 300. Furthermore, the handle groove 303 and the second limiting protrusion 302 are located on the same side of the cover 310, which makes it easier and less strenuous to remove the control panel 300 from the outer casing 100.

[0071] Since both the first snap-fit ​​structure 206 and the second snap-fit ​​structure 301 are protruding structures, in order to smoothly achieve the sliding engagement of the control panel 300, the baffle box structure 200, and the outer shell 100, a first clearance structure 208 is provided on the circumferential edge 202 to allow the second snap-fit ​​structure 301 to slide, and a second clearance structure 304 is provided on the control panel 300 to allow the first snap-fit ​​structure 206 to slide. Optionally, the first clearance structure 208 is a clearance groove; if there are eight second snap-fit ​​structures 301, then there are also eight first clearance structures 208. Optionally, the cavity formed by the cover plate and the side wall of the cover body 310 is the second clearance structure 304.

[0072] This utility model also discloses a water heater, which includes an inner tank, an end cap, and the aforementioned baffle box assembly 10. The inner tank is placed inside the outer shell 100, and the end cap is closed at the opening of the outer shell 100. By using the aforementioned baffle box assembly 10, not only is the probability of water overflow reduced, but the cost of preventing overflow is also reduced, resulting in better product quality. Furthermore, the assembly steps are simplified, thus improving assembly efficiency.

[0073] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
