[0070] See also Figure 1 , Figure 1 The schematic diagram of the installation of a household appliance on a mounting base 40 in an embodiment of the present application is shown. The household appliance provided in an embodiment of the present application includes a housing structure and an electrical component 30. The housing structure includes an accessory space 10 and a hanging hole 12. The accessory space 10 is formed inside the housing structure and is used to accommodate the electrical component 30 of the household appliance. The electrical component 30 may be a circuit board, a sensor, a solenoid valve, a conductive wire or other energized component of the household appliance. By installing the electrical component 30 in the internal space of the housing structure, the electrical component 30 can be protected, and the electrical component 30 can be prevented from being exposed to the external environment, which affects the service life of the electrical component 30. At the same time, it can also prevent users from touching the electrical component 30 and causing electric shock accidents.

[0071] Furthermore, the housing structure further includes a hanging hole 12, which is formed on the outer wall of the housing structure, and is used to accommodate a fastener 31, which is provided on a mounting base 40 for mounting the household appliance. When the fastener 31 is installed on the mounting base 40 and penetrates through the hanging hole 12, the fastener 31 can abut against the inner wall of the hanging hole 12, so that the housing structure is hung on the mounting base 40 through the fastener 31.

[0072] Specifically in one embodiment, the installation base 40 is a wall, the household appliance is a pipeline machine, and the fastener 31 is a screw. During the installation of the pipeline machine, the screw is first fixed to the wall by drilling or directly knocking in, then the hanging hole 12 of the pipeline machine is aligned with the screw, and the screw is inserted into the hanging hole 12, and finally the pipeline machine is loosened, and the pipeline machine is hung on the screw, thereby realizing the installation of the pipeline machine on the wall.

[0073] It should be noted that the household appliance may also be a television, an air conditioner, or other appliance that needs to be fixed on a wall, and the fastener 31 may also be a hook, and the mounting base 40 may also be glass or the like.

[0074] In actual use, the conventional hanging hole 12 is usually formed by a through-hole structure on the shell structure, and the hanging hole 12 of the through-hole structure has the following problems:

[0075] 1. Affecting the visual experience and overall aesthetics. Before the whole machine is installed, the through-hole structure will expose the internal structure of household appliances such as pipeline machines, affecting the user's visual experience and overall aesthetics, and reducing the high-end feel of the product.

[0076] 2 Increase the risk of long-term reliability quality. When the through-hole structure is installed on an uneven wall or not close to the wall, water, air, dust and insects can easily enter the interior of the shell structure, which may cause quality problems such as circuit short circuits in circuit components, affecting the long-term stable operation of household appliances.

[0077] 3. There are electrical safety hazards. When the through-hole structure is used without the user installing the household appliance on the wall, for example, when the pipeline machine is in the trial prototype stage or is placed directly on the countertop as a desktop water purifier, people's hands can easily touch the internal circuits and other electrical components, which poses an electrical safety hazard and poses a threat to user safety.

[0078] To this end, in the shell structure provided by the present application, the internal space of the hanging hole 12 is independent of the accessory space 10. In this way, while ensuring the hanging function of the hanging hole 12, it can firstly avoid the problem of the user's hands touching the electrical components 30 before the household appliance is installed or when the household appliance is not installed on the wall for use, and at the same time it can also increase the visual experience and overall aesthetics.

[0079] Secondly, after the housing structure is installed on the mounting base 40, since the hanging hole 12 is not connected to the accessory space 10, as shown in FIG. Figure 5 , Fig.11 and 17 As shown in any of the embodiments, the arrows in the figures are the movement directions of materials such as water, gas, and impulse. External materials will only flow outside the hanging hole 12 and the accessory space 10 and will not enter the accessory space 10. Therefore, it is possible to prevent materials such as water, gas, and insects from entering the accessory space 10 to affect the normal operation of the electrical components 30, thereby improving quality reliability.

[0080] In some embodiments of the present application, the shell structure also forms a hanging space 11, which is independent of the accessory space 10, and the hanging hole 12 is connected to the hanging space 11, wherein the size of the hanging space 11 is larger than the size of the hanging hole 12, and the hanging hole 12 is located in the middle of the inner wall of the hanging space 11, so that the hanging space 11 still has a certain space above the hanging hole 12.

[0081] Among them, the end of the fastener 31 away from the installation base 40 extends into the hanging space 11, and part of the fastener 31 is located above the hanging hole 12, so that the fastener 31 fixes the shell structure in a hooking manner. In actual use, if the hanging hole 12 is a blind hole, although it can also prevent water, air, insects and other materials from entering the accessory space 10 to affect the normal operation of the electrical component 30, the fastener 31 set in the hanging hole 12 can only limit the movement of the shell structure in the up and down directions, and cannot limit the axial direction of the hanging hole 12, so that the shell structure can easily slip off the fastener 31, causing the household appliance to fall to the ground and be damaged.

[0082] Through the above-mentioned hanging space 11, the fastener 31 is hooked in the hanging hole 12 and the hanging space 11, so that the fastener 31 can not only limit the upper and lower directions of the housing structure, but also limit the movement of the housing structure in the axial direction of the hanging hole 12. That is, when the fastener 31 is hooked in the hanging hole 12, when the housing structure moves along the hanging hole 12, the housing structure will be hooked by the fastener 31, reducing the probability of the household appliance falling off.

[0083] Specifically, the fastener 31 includes a head 32 and a rod 33, the head 32 is connected to one end of the rod 33, the other end of the rod 33 is connected to the mounting base 40, the diameter of the head 32 is greater than the diameter of the rod 33, and the head 32 is located in the hanging space 11, and the rod 33 is inserted into the hanging hole 12. In this way, the housing assembly can be hung on the fastener 31 by the abutment between the head 32 and the inner wall of the hanging space 11.

[0084] Further, see Figure 3 Since the diameter of the head 32 is greater than the diameter of the rod 33, it is not convenient for the head 32 to enter the hanging space 11 through the hanging hole 12. For this reason, in some embodiments, the hanging hole 12 includes a first sub-hole 15 and a second sub-hole 16. The first sub-hole 15 and the second sub-hole 16 are both located on the same plane of the shell structure and are connected to each other. The diameter of the first sub-hole 15 is greater than the diameter of the second sub-hole 16, and when the mounting structure is installed, the first sub-hole 15 is located below the second sub-hole 16.

[0085] Among them, the diameter of the head 32 is smaller than the first sub-hole 15 and larger than the second sub-hole 16, and the diameter of the rod 33 is smaller than the second sub-hole 16. When the shell structure needs to be hung, the head 32 can be inserted into the hanging space 11 through the first sub-hole 15, and then the shell structure is loosened. Under the action of gravity, the rod 33 will move into the second sub-hole 16, so that the installation structure is hung on the fastener 31.

[0086] In some embodiments of the present application, in order to increase the production speed of the shell structure and also to reduce the production cost of the shell structure, various components in the shell structure are injection molded. During the injection molding process, since the hanging space 11 exists independently, after the shell structure is molded, the mold in the hanging space 11 cannot be normally separated from the hanging space 11, resulting in demolding difficulties.

[0087] For this purpose, see Figures 2 to 7 ,exist Figures 2 to 7 In a shell structure provided in the present application, the outer wall of the shell structure also has a side withdrawal hole 13, and a hanging space 11 is formed in the side withdrawal hole 13. The axial direction of the side withdrawal hole 13 intersects with the axial direction of the hanging hole 12, that is, the hanging hole 12 penetrates to the inner wall of the side withdrawal hole 13.

[0088] Thus, in the shell structure of this embodiment, when it is necessary to injection mold a component having a side withdrawal hole 13 and a hanging hole 12, a sliding mold 50 can be added on the basis of the movable mold and the fixed mold. The movement direction of the sliding mold 50 relative to the fixed mold is added to the movement direction of the movable mold relative to the fixed mold. The component having the side withdrawal hole 13 and the hanging hole 12 is jointly molded by the sliding mold 50, the movable mold and the fixed mold.

[0089] Among them, after the component is formed, Figure 6 As shown, the sliding mold 50 is located in the side withdrawal hole 13, and the movement direction of the sliding mold 50 relative to the fixed mold is parallel to the axis of the side withdrawal hole 13, so that the sliding mold 50 can be withdrawn from the side withdrawal hole 13 during the movement. Figure 7 , and then control the movable mold to separate from the fixed mold to complete the demoulding of the component.

[0090] Specifically, see Figure 2 and Figure 3 The shell structure includes a first shell 20 and a second shell 21. The second shell 21 is covered on the first shell 20 and spliced ​​with the first shell 20 to form an accessory space 10. Among them, a hanging hole 12 is formed at one end of the first shell 20 away from the second shell 21, and a side withdrawal hole 13 is opened on the side wall of the first shell 20. During the injection molding process of the first shell 20, the fixed mold and the movable mold are respectively located on both sides of the first shell 20 in the axial direction of the hanging hole 12, and the sliding mold 50 is penetrated between the fixed mold and the movable mold. After the first shell 20 is injection molded, the sliding mold 50 will be penetrated in the side withdrawal hole 13. When the first shell 20 is demolded, the sliding module can be pulled out first, and then the movable mold and the fixed mold are separated to complete the demolding of the first shell 20.

[0091] It is understandable that since the second shell 21 is not provided with the hanging hole 12 and the hanging space 11, the second shell 21 can be directly injection molded using the traditional fixed mold and movable mold method without a slider mold. After injection molding, the second shell 21 and the first shell 20 are then spliced ​​with each other by bolts or the like to form the accessory space 10.

[0092] Further, based on this application Figures 2 to 7 The first housing 20 in the embodiment, the embodiment of the present application also provides an injection mold for molding Figures 2 to 7 The first shell 20 in the embodiment. The injection mold includes a fixed mold, a movable mold and a sliding mold 50, the movable mold can move relative to the fixed mold along a first direction, the sliding mold 50 can move relative to the fixed mold along a second direction intersecting the first direction, and the fixed mold, the movable mold and the sliding mold 50 together constitute an injection space for forming the first shell 20.

[0093] Among them, when the first shell 20 is formed in the injection molding space, the axial direction of the side withdrawal hole 13 on the first shell 20 is parallel to the second direction, and the sliding mold 50 can be pulled out of the side withdrawal hole 13 during the movement along the second direction, and then the movable mold is controlled to move along the first direction, so that the movable mold and the fixed mold are separated from each other, and finally the demolding of the first shell 20 is completed.

[0094] In some other embodiments, see Figures 8 to 13 , while Figure 8 - Fig.13 In the embodiment of the present invention, the housing structure includes a first housing 20, a second housing 21 and a mounting boss 22. The mounting boss 22 is disposed on the outer surface of the first housing 20, and a hanging hole 12 is disposed at one end of the mounting boss 22 away from the first housing 20. A side draw hole 13 is provided on the circumferential side wall of the mounting boss 22, and a hanging space 11 is formed inside the side draw hole 13. The second housing 21 is covered on one side of the first housing 20 away from the mounting boss 22, and is spliced ​​with the first housing 20 to form an accessory space 10.

[0095] Compared to Figures 2 to 7 The housing structure in the embodiment, Figures 8 to 13 The shell structure in the embodiment forms the side draw-out hole 13 and the hanging hole 12 on the mounting boss 22 on the outer surface of the first shell 20 , so that the hanging space 11 does not encroach on the internal space of the first shell 20 , thereby increasing the capacity of the accessory space 10 .

[0096] The first housing 20 and the mounting boss 22 are integrally formed by injection molding. Figures 2 to 7The injection mold in the embodiment is the same, and the injection mold includes a fixed mold, a movable mold and a sliding mold 50. The fixed mold, the movable mold and the sliding mold 50 together form a molding space for molding the first shell 20 and the mounting boss 22. After the first shell 20 and the mounting boss 22 are molded, the sliding mold 50 is located in the side draw hole 13, such as Fig.12 When demolding is performed later, the sliding mold 50 is firstly pulled out from the side withdrawal hole 13, and finally the movable mold is separated from the fixed mold, and the demolding of the first housing 20 and the mounting boss 22 is completed.

[0097] based on Figures 8 to 13 In the embodiment, the first housing 20 and the mounting boss 22 are provided. The present application also provides an injection mold for molding Figures 8 to 13 The first shell 20 and the mounting boss 22 are formed by the injection mold, and the injection mold includes a fixed mold, a movable mold and a sliding mold 50. The movable mold can move relative to the fixed mold along a first direction, and the sliding mold 50 can move relative to the fixed mold along a second direction intersecting the first direction. The fixed mold, the movable mold and the sliding mold 50 together constitute an injection space for forming the first shell 20 and the mounting boss 22.

[0098] Among them, when the first shell 20 and the mounting boss 22 are formed in the injection molding space, the axial direction of the side withdrawal hole 13 on the mounting boss 22 is parallel to the second direction, and the sliding mold 50 can be pulled out of the side withdrawal hole 13 during the movement along the second direction, and then the movable mold is controlled to move along the first direction, so that the movable mold and the fixed mold are separated from each other, and finally the demolding of the first shell 20 and the mounting boss 22 is completed.

[0099] Further, see Fig.14 - Fig.17 The present application also provides a shell structure, which includes a molding hole 14. The molding hole 14 and the hanging hole 12 are both located on the same surface of the shell structure. The inner wall of the molding hole 14 is formed with a side draw hole 13. The inside of the side draw hole 13 is formed with a hanging space 11, that is, the hanging hole 12 penetrates the inner wall of the side draw hole 13. In this way, the side draw hole 13 and the molding hole 14 form a barb space, so that the inclined top 51 in the injection mold can be inserted into the hanging hole 12 through the molding hole 14, and then used to shape the hanging space 11.

[0100] Compared to Figure 2 - Figure 7 The housing structure in the embodiment, Fig.14 - Fig.17 The shell structure hanging holes 12 and forming holes 14 in the embodiment are both on the same surface of the shell structure. When the shell structure is hung on the wall, the hanging holes 12 and the forming holes will be shielded by the wall, thereby making the appearance of the shell structure more regular.

[0101] Compared with Figure 8 - Fig.13 The housing structure in the embodiment, Fig.14 - Fig.17 The housing structure in the embodiment does not have a protruding mounting boss 22, so that the accessory space 10 occupied by the housing structure is smaller, making it more convenient to install the housing structure.

[0102] Specifically, the shell structure includes a first shell 20 and a second shell 21. The first shell 20 and the second shell 21 are spliced ​​to form an accessory space 10. The first shell 20 is provided with a molding hole 14 and a hanging hole 12. The first shell 20 is integrally formed by injection molding. Specifically, the top of the inclined top 51 includes an undercut portion and an ejection portion arranged at an angle, and the undercut portion and the ejection portion form a shape similar to "7". After the first shell 20 is injection molded, the undercut portion will be inserted into the hanging hole 12. At this time, the fixed mold and the movable mold are first controlled to separate, and then the inclined top 51 is controlled to move. While the inclined top 51 ejects the first shell 20 from the fixed mold, it also causes the undercut portion to be pulled out of the side withdrawal hole 13. Finally, in the process of removing the first shell 20, the inclined top 51 leaves the first shell 20 from the molding hole 14 to complete.

[0103] based on Figures 14 to 17 In the embodiment, the first housing 20 is provided. The present application also provides an injection mold for forming Figures 14 to 17 The first shell 20 is formed by the injection mold, which includes a fixed mold, a movable mold, and a tilted ejector 51. The movable mold is movable along a first direction relative to the fixed mold. The tilted ejector 51 is penetrated by the movable mold and is movable along a second direction relative to the movable mold. The second direction intersects with the first direction. The fixed mold, the movable mold and the tilted ejector 51 together constitute an injection space for forming the first shell 20.

[0104] When the first shell 20 is formed in the injection molding space, the axial direction of the side withdrawal hole 13 is parallel to the second direction, and the axial direction of the molding hole 14 is parallel to the first direction, and the inclined ejector 51 can be pulled out of the side withdrawal hole 13 during the movement along the second direction. In actual use, the first direction is the vertical direction, and the second direction is the oblique upward direction. In this way, after the fixed mold and the movable mold are separated, the inclined ejector 51 can not only be pulled out of the side withdrawal hole 13 during the oblique upward movement, but also can eject the first shell 20 from the movable mold. After the inclined ejector 51 is pulled out of the side withdrawal hole 13, the inclined ejector 51 is still located in the molding hole 14, and in the process of removing the first shell 20, the inclined ejector 51 can be pulled out of the first shell 20 through the molding hole 14, thereby completing the separation of the first shell 20 from the injection mold.

[0105] The above shell structure has at least the following advantages:

[0106] The internal space of the hanging hole 12 is independent of the accessory space 10. In this way, while ensuring the hanging function of the hanging hole 12, it can firstly avoid the problem that the household appliance is not installed before, or when the user uses the household appliance before it is installed on the wall, the human hand will touch the electrical component 30, and at the same time it can also increase the visual experience and overall aesthetics.

[0107] After the shell structure is installed on the mounting base 40, since the hanging hole 12 is not connected to the accessory space 10, external materials will only flow outside the hanging hole 12 and the accessory space 10 and will not enter the accessory space 10. Therefore, it can prevent water, air, insects and other materials from entering the accessory space 10 to affect the normal operation of the electrical components 30, thereby improving quality reliability.

[0108] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0109] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
