Housing structure, household appliance and injection mold

Abstract

This application relates to a housing structure for a household appliance. The housing structure includes: a fitting space formed inside the housing structure for accommodating electrical components of the household appliance; and a hanging hole formed on the outer wall of the housing structure for accommodating fasteners. The fasteners are mounted on a mounting base for installing the household appliance, and the internal space of the hanging hole is independent of the mounting space. Because the internal space of the hanging hole is independent of the mounting space, after the housing structure is installed on the mounting base, since the hanging hole is not connected to the mounting space, external materials will only flow outside the hanging hole and the mounting space and will not enter the mounting space. Therefore, it can prevent water, air, insects, and other materials from entering the mounting space and affecting the normal operation of the electrical components, thus improving quality and reliability.

Description

[0001] This application relates to the field of drinking water equipment technology, and in particular to a housing structure, household appliance, and injection mold. Background Technology

[0002] A water dispenser, also known as a piped water purifier or wall-mounted piped water purifier, is generally used in homes, offices, schools, etc., in conjunction with water purification equipment. Existing water dispensers include an inlet pipe, inlet control components, a water tank, a water tank cover, a drain pipe, and water treatment equipment. Water is drawn into the water tank through the inlet pipe and flows into the water treatment equipment through the drain pipe.

[0003] Currently, most water dispensers are fixed to the wall by drilling hanging holes in the outer casing and using hooks or bolts installed on the wall. However, due to uneven walls or improper installation, water, air, dust, and insects from the surrounding environment can easily enter the water dispenser through the hanging holes, potentially causing short circuits and other quality problems, affecting the long-term stable operation of the water dispenser. Summary of the Invention

[0037] In the aforementioned shell structure, the internal space of the hanging hole and the accessory space are independent of each other. In this way, while ensuring the hanging function of the hanging hole, it can firstly prevent the problem of people touching electrical components before the appliance is installed or when the user is using the appliance without it being installed on the wall. At the same time, it can also enhance the visual experience and overall aesthetics.

[0038] After the shell structure is installed on the mounting foundation, since the hanging holes are not connected to the accessory space, external materials will only flow outside the hanging holes and accessory space and will not enter the accessory space. Therefore, it can prevent water, air, insects and other materials from entering the accessory space and affecting the normal operation of electrical components, thus improving quality and reliability.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0065] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0066] Furthermore, where the terms "first" and "second" appear, these terms are 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 with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0069] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0070] See Figure 1 , Figure 1 This illustration shows a schematic diagram of a household appliance installed on a mounting base 40 according to an embodiment of this application. The household appliance provided in this embodiment includes a housing structure and electrical components 30. The housing structure includes a fitting space 10 and hanging holes 12. The fitting space 10 is formed inside the housing structure and is used to accommodate the electrical components 30 of the household appliance. The electrical components 30 can be circuit boards, sensors, solenoid valves, conductive wires, or other electrically conductive parts of the household appliance. By installing the electrical components 30 within the internal space of the housing structure, protection is provided for the electrical components 30, preventing them from being exposed to the external environment and affecting their service life. It also prevents users from touching the electrical components 30 and causing electric shock accidents.

[0071] Furthermore, the housing structure also includes a hanging hole 12, which is formed on the outer wall of the housing structure. The hanging hole 12 is used to receive a fastener 31, which is provided on the mounting base 40 for installing household appliances. When the fastener 31 is installed on the mounting base 40 and passes through the hanging hole 12, the fastener 31 can abut against the inner wall of the hanging hole 12, thereby hanging the housing structure on the mounting base 40 by means of the fastener 31.

[0072] In one specific embodiment, the mounting base 40 is a wall, the household appliance is a water dispenser, and the fastener 31 is a screw. During the installation of the water dispenser, the screw is first fixed to the wall by drilling or hammering. Then, the hanging hole 12 of the water dispenser is aligned with the screw, and the screw is inserted into the hanging hole 12. Finally, the water dispenser is released, and it will hang on the screw, thus realizing the installation of the water dispenser on the wall.

[0073] It should be noted that household appliances can also include televisions, air conditioners, and other appliances that need to be fixed to the wall, and fastener 31 can also be a hook, and mounting base 40 can also be glass, etc.

[0074] In actual use, traditional hanging holes 12 are usually formed by through holes in the shell structure. However, through holes have the following problems:

[0075] 1. It affects 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 water dispensers, which will affect the user's visual experience and overall aesthetics, and reduce the product's high-end feel.

[0076] 2. Increased long-term reliability and quality risks: When the wall is uneven or the appliance is not installed close to the wall, water, air, dust and insects can easily enter the interior of the casing, which may cause short circuits and other quality problems, affecting the long-term stable operation of the household appliance.

[0077] 3. There are electrical safety hazards. When the user does not install the household appliance on the wall, such as when the water dispenser is in the trial stage or when it is used as a countertop water purifier, the user's hand can easily touch the internal wiring and other electrical components, which poses an electrical safety hazard and threatens the user's safety.

[0078] Therefore, in the housing structure provided in this application, the internal space of the hanging hole 12 and the accessory space 10 are independent of each other. In this way, while ensuring the hanging function of the hanging hole 12, it can first avoid the problem that the user's hand will touch the electrical component 30 before the household appliance is installed or when the household appliance is not installed on the wall. At the same time, it can also enhance the visual experience and overall aesthetics.

[0079] Secondly, after the shell structure is installed on the mounting base 40, since the hanging hole 12 is not connected to the accessory space 10, such as Figure 5 , Figure 11 and 17 As shown in any embodiment, the arrows in each figure indicate the direction of movement of materials such as water, air, and insects. 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 materials such as water, air, and insects from entering the accessory space 10 and affecting the normal operation of the electrical components 30, thereby improving the quality and reliability.

[0080] In some embodiments of this application, the shell structure further forms a hanging space 11, which is independent of the accessory space 10. 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] In this design, the end of the fastener 31 furthest from the mounting base 40 extends into the hanging space 11, and part of the fastener 31 is located above the hanging hole 12, thus fixing the housing structure in a hook-like manner. In actual use, if the hanging hole 12 is a blind hole, although it can still prevent water, air, insects, and other materials from entering the accessory space 10 and affecting the normal operation of the electrical components 30, the fastener 31 in the hanging hole 12 can only limit the vertical movement of the housing structure, not the axial movement of the hanging hole 12. This makes it easy for the housing structure to slip off the fastener 31, causing the household appliance to fall to the ground and be damaged.

[0082] The hanging space 11 allows the fastener 31 to be hooked within the hanging hole 12 and the hanging space 11. This enables the fastener 31 to not only limit the vertical movement of the housing structure but also to limit its movement along the axis of the hanging hole 12. In other words, when the fastener 31 is hooked within the hanging hole 12, the housing structure will be caught by the fastener 31 as it moves along the direction of the hanging hole 12, reducing the probability of the appliance falling off.

[0083] Specifically, the fastener 31 includes a head 32 and a rod 33. One end of the head 32 is connected to one end of the rod 33, and the other end of the rod 33 is connected to the mounting base 40. The diameter of the head 32 is larger than the diameter of the rod 33, and the head 32 is located within the hanging space 11. The rod 33 passes through the hanging hole 12. Thus, by the contact between the head 32 and the inner wall of the hanging space 11, the housing assembly can be hung on the fastener 31.

[0084] Further, see Figure 3 Since the diameter of the head 32 is larger 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. Therefore, 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 interconnected. The diameter of the first sub-hole 15 is larger 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] The diameter of the head 32 is smaller than that of the first sub-hole 15 and larger than that of the second sub-hole 16. The diameter of the rod 33 is smaller than that of the second sub-hole 16. When it is necessary to hang the shell structure, the head 32 can be inserted into the hanging space 11 through the first sub-hole 15 first. Then the shell structure is released. 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 this application, in order to improve the production speed of the shell structure and reduce the production cost of the shell structure, each component in the shell structure is injection molded. However, during the injection molding process, since the hanging space 11 exists independently, the mold in the hanging space 11 cannot be properly detached from the hanging space 11 after the shell structure is formed, resulting in demolding difficulties.

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

[0088] Thus, in the housing structure of this embodiment, when it is necessary to injection mold a part with a side pull hole 13 and a hanging hole 12, a sliding mold 50 can be added on the basis of the moving 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 moving mold relative to the fixed mold. The part with the side pull hole 13 and the hanging hole 12 is formed by the sliding mold 50, the moving mold and the fixed mold together.

[0089] Once the component is formed, such as Figure 6 As shown, the sliding mold 50 is located inside the side extraction hole 13, and the direction of movement of the sliding mold 50 relative to the fixed mold is parallel to the axis of the side extraction hole 13, so that the sliding mold 50 can be pulled out of the side extraction hole 13 during the movement. See here. Figure 7 Then, the moving mold and the fixed mold are separated to complete the demolding of the part.

[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 covers the first shell 20 and is joined with the first shell 20 to form an accessory space 10. A hanging hole 12 is formed at the end of the first shell 20 away from the second shell 21, and a side-pull hole 13 is formed on the side wall of the first shell 20. During the injection molding process, the fixed mold and the moving mold are located on opposite sides of the first shell 20 along the axis of the hanging hole 12. A sliding mold 50 passes between the fixed mold and the moving mold. After the first shell 20 is injection molded, the sliding mold 50 will be inserted into the side-pull hole 13. When demolding the first shell 20, the sliding mold can be pulled out first, and then the moving mold and the fixed mold can be separated to complete the demolding of the first shell 20.

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

[0092] Furthermore, based on this application Figures 2 to 7 The first housing 20 in the embodiment, and the injection mold provided in this application embodiment for molding Figures 2 to 7 The first housing 20 in the embodiment. The injection mold includes a fixed mold, a movable mold, and a sliding mold 50. The movable mold is movable relative to the fixed mold along a first direction, and the sliding mold 50 is movable 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 form an injection space for forming the first housing 20.

[0093] When the first housing 20 is formed in the injection space, the axial direction of the side extraction hole 13 on the first housing 20 is parallel to the second direction. The sliding mold 50 can be pulled out of the side extraction hole 13 during the movement along the second direction. Then, the moving mold is controlled to move along the first direction, so that the moving mold and the fixed mold are separated from each other, and finally the demolding of the first housing 20 is completed.

[0094] In some other embodiments, see Figures 8 to 13 , and Figure 8 - Figure 13 In this embodiment, 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 provided at the end of the mounting boss 22 away from the first housing 20. A side pull hole 13 is provided on the circumferential side wall of the mounting boss 22, and a hanging space 11 is formed inside the side pull hole 13. The second housing 21 is covered on the 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 shell structure in the embodiment, Figures 8 to 13 In the embodiment, the housing structure forms the side pull hole 13 and the hanging hole 12 on the mounting boss 22 on the outer surface of the first housing 20, so that the hanging space 11 does not encroach on the internal space of the first housing 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, and are used for molding. Figures 2 to 7In this embodiment, the injection mold is identical, comprising a fixed mold, a movable mold, and a sliding mold 50. The fixed mold, movable mold, and sliding mold 50 together form a molding space for molding the first housing 20 and the mounting boss 22. After the first housing 20 and the mounting boss 22 are molded, the sliding mold 50 is located within the side extraction hole 13, as shown below. Figure 12 As shown. Then, during demolding, the sliding mold 50 is first pulled out from the side extraction hole 13, and finally the moving mold is separated from the fixed mold to complete the demolding of the first housing 20 and the mounting boss 22.

[0097] based on Figures 8 to 13 The embodiment includes a first housing 20 and a mounting boss 22. This application also provides an injection mold for molding. Figures 8 to 13 The first housing 20 and the mounting boss 22 are included in the injection mold. The injection mold includes a fixed mold, a movable mold and a sliding mold 50. The movable mold is movable relative to the fixed mold along a first direction, and the sliding mold 50 is movable 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 form an injection space for forming the first housing 20 and the mounting boss 22.

[0098] When the first housing 20 and the mounting boss 22 are formed in the injection space, the axial direction of the side extraction hole 13 on the mounting boss 22 is parallel to the second direction. The sliding mold 50 can extract the side extraction hole 13 during the movement along the second direction. Then, the moving mold is controlled to move along the first direction, so that the moving mold and the fixed mold are separated from each other, and finally the demolding of the first housing 20 and the mounting boss 22 is completed.

[0099] Further, see Figure 14 - Figure 17 This application also provides a housing structure including a molding hole 14. The molding hole 14 and the hanging hole 12 are both located on the same surface of the housing structure. A side-pull hole 13 is formed on the inner wall of the molding hole 14, and a hanging space 11 is formed inside the side-pull hole 13, that is, the hanging hole 12 extends through the inner wall of the side-pull hole 13. In this way, the side-pull hole 13 and the molding hole 14 form a barbed space, so that the inclined ejector 51 in the injection mold can be inserted into the hanging hole 12 through the molding hole 14, thereby forming the hanging space 11.

[0100] Compared to Figure 2 - Figure 7 The shell structure in the embodiment, Figure 14 - Figure 17 In the embodiment, the hanging hole 12 and the forming hole 14 of the shell structure are on the same surface of the shell structure. When the shell structure is hung on the wall, the hanging hole 12 and the forming hole will be covered by the wall, thus making the appearance of the shell structure more regular.

[0101] Compared to Figure 8 - Figure 13 The shell structure in the embodiment, Figure 14 - Figure 17 The housing structure in this embodiment does not have a protruding mounting boss 22, so that the accessory space 10 occupied by the housing structure is smaller and the installation of the housing structure is more convenient.

[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 joined 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 molded by injection molding. Specifically, the top of the inclined ejector 51 includes an undercut and an ejector portion arranged at an angle, forming a shape similar to "7". After the first shell 20 is injection molded, the undercut portion is inserted into the hanging hole 12. At this time, the fixed mold and the moving mold are separated first, and then the inclined ejector 51 is moved. The inclined ejector 51 ejects the first shell 20 out of the fixed mold, and at the same time, the undercut portion is pulled out of the side extraction hole 13. Finally, during the process of removing the first shell 20, the inclined ejector 51 leaves the first shell 20 through the molding hole 14, completing the process.

[0103] based on Figures 14 to 17 In the embodiment, a first housing 20 is provided. This application also provides an injection mold for molding. Figures 14 to 17 The first housing 20 is an injection mold comprising a fixed mold, a movable mold, and an inclined ejector 51. The movable mold is movable relative to the fixed mold along a first direction. The inclined ejector 51 is mounted on the movable mold and is movable relative to the movable mold along a second direction. The second direction intersects with the first direction. The fixed mold, the movable mold, and the inclined ejector 51 together form an injection space for forming the first housing 20.

[0104] When the first housing 20 is formed in the injection space, the axis of the side extraction hole 13 is parallel to the second direction, and the axis of the forming hole 14 is parallel to the first direction. The inclined ejector 51 can be pulled out of the side extraction hole 13 during its movement along the second direction. In actual use, the first direction is vertical, and the second direction is obliquely upward. Thus, after the fixed mold and the moving mold separate, the inclined ejector 51, during its obliquely upward movement, can not only be pulled out from the side extraction hole 13 but also eject the first housing 20 from the moving mold. After the inclined ejector 51 is pulled out from the side extraction hole 13, it remains within the forming hole 14. During the removal of the first housing 20, the inclined ejector 51 can be pulled out of the first housing 20 through the forming hole 14, thereby completing the separation of the first housing 20 from the injection mold.

[0105] The above-mentioned 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 first avoid the problem that the user's hand will touch the electrical component 30 before the household appliance is installed or when the household appliance is not installed on the wall. At the same time, it can also enhance the visual experience and overall aesthetics.

[0107] After the housing 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 and affecting the normal operation of the electrical components 30, thus improving the quality and reliability.

[0108] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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 embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
