Detailed Implementation

[0034] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0035] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0036] When the door of the housing is opened relative to the box, the maximum opening angle of the door is fixed, which makes the door prone to collision with obstacles behind it, thus causing the door to bump and knock.

[0037] The door assembly 10 and the receiving device of the present disclosure are described below with reference to Figures 1-12.

[0038] This disclosure provides a receiving device, which includes a housing 20 and a door assembly 10. The housing 20 has a storage space inside, and the door assembly 10 is connected to the housing 20 and is used to open or close the housing 20 to facilitate the user's retrieval and placement.

[0039] In some embodiments, the housing includes a refrigerator, washing machine 100, dryer or other products with a door opening mechanism, which are not limited thereto.

[0040] The following description uses a washing machine 100 as an example of a housing device. The washing machine 100 includes a cabinet 20 and a door assembly 10. The door assembly 10 is connected to the cabinet 20 and is used to open or close the cabinet 20 so that the user can take out and put in clothes.

[0041] However, in some usage scenarios, the washing machine 100 is in a confined space and there is an obstacle on one side of the door 2 in the opening direction. When the user opens the door to the maximum opening angle, the door 2 is prone to collision or bumping with the obstacle, which may lead to damage to the door 2.

[0042] In response, this disclosure proposes a door assembly 10.

[0043] Please refer to Figures 2 and 3. The door assembly 10 includes: a mounting base 1, a door body 2, and a limiting member 3.

[0044] Mounting base 1 is suitable for installation on housing 20. For example, mounting base 1 can be a hinge, and mounting base 1 can be detachably connected to housing 20. For example, mounting base 1 can be connected to housing 20 by bolts or snap-fit. This facilitates the disassembly and installation of door assembly 10 and housing 20, and helps reduce the difficulty of assembly and disassembly of door assembly 10. Of course, mounting base 1 can also be fixedly connected to housing 20 by welding to enhance the connection stability between mounting base 1 and housing 20.

[0045] The door 2 is rotatably mounted on the mounting base 1 to open or close the housing 20. This allows the door 2 to rotate relative to the mounting base 1, thereby enabling the door 2 to rotate relative to the housing 20 and thus opening or closing the housing 20. For example, the mounting base 1 may be provided with a pivot, and the door 2 may be provided with a bushing fitted onto the pivot, thereby achieving a rotatable connection between the door 2 and the mounting base 1 and enhancing the rotational stability of the door 2 and the mounting base 1.

[0046] The limiting component 3 is detachably installed on the mounting base 1. For example, the limiting component 3 can be connected to the mounting base 1 by means of snap-fit, plug-in, magnetic attraction or bolt connection. This allows the user to flexibly select the limiting component 3 according to their needs, and the installation and removal process of the limiting component 3 does not require disassembly of the receiving device, so as to reduce the difficulty of installing and removing the limiting component 3 and improve the efficiency of installing and removing the limiting component 3.

[0047] In the direction of rotation of the door 2, at least a portion of the limiting member 3 protrudes from the mounting base 1, and when the door 2 opens the housing 20, the limiting member 3 engages with the door 2 in a limiting engagement. It is understood that the door 2 is adapted to open relative to the housing 20 (i.e., when the door 2 is opened to its maximum opening angle), so that the limiting member 3 engages with the door 2 in a limiting engagement.

[0048] It is understandable that, as shown in Figure 5, when the limiting member 3 is not installed on the mounting base 1, when the door 2 opens the box 20, the door 2 will rotate to be limited by the mounting base 1 to achieve the maximum opening angle (angle A0 in Figure 5). However, in this disclosure, as shown in Figure 5, at least a portion of the limiting member 3 protrudes from the mounting base 1 in the rotation direction of the door 2, so that when the door 2 opens the box 20, the door 2 will first be limited and engaged with the limiting member 3. In this way, the maximum opening angle of the door 2 (angle A2 in Figure 5) can be reduced compared to the case where the limiting member 3 is not installed.

[0049] This limits the maximum opening angle of the door 2, thereby reducing the risk of the door 2 colliding with obstacles behind it, and thus reducing the impact on the door 2, which serves to protect the door 2.

[0050] According to the door assembly 10 of the present disclosure, at least a portion of the limiting member 3 protrudes from the mounting base 1, so that the limiting member 3 and the door 2 can limit the maximum opening angle of the door 2, thereby reducing the risk of the door 2 colliding with obstacles behind the door, and thus reducing the impact on the door 2, so as to protect the door 2. The limiting member 3 is detachably installed on the mounting base 1, so that the user can flexibly select and install it according to the needs. The installation and removal process of the limiting member 3 does not require disassembly and assembly of the receiving device, so as to reduce the difficulty of installing and removing the limiting member 3 and improve the efficiency of installing and removing the limiting member 3.

[0051] In some embodiments, as shown in FIG5, the mounting base 1 is provided with a limiting rib 11, and the surface of the limiting member 3 away from the limiting rib 11 is formed as a limiting surface 301, which is used to abut against the door body 2.

[0052] As can be understood, as shown in Figure 6, when the limiting member 3 is not installed on the mounting base 1, as shown in Figure 7, the door 2 engages with the limiting rib 11 when the housing 20 is opened, as shown in Figure 8. When the limiting member 3 is installed on the mounting base 1, as shown in Figure 9, the door 2 will first abut against the limiting surface 301 when the housing 20 is opened. The limiting surface 301 is the surface of the limiting member 3 away from the limiting rib 11. Therefore, the installation of the limiting member 3 reduces the maximum opening angle of the door 2 compared to the case without the limiting member 3. This limits the maximum opening angle of the door 2, thereby reducing the risk of the door 2 colliding with obstacles behind it, and thus reducing the risk of the door 2 being bumped or knocked, thus protecting the door 2.

[0053] In some embodiments, the angle between the limiting surface 301 and the limiting rib 11 is inversely proportional to the maximum opening angle of the door body 2.

[0054] It is understandable that, referring to Figure 5, when the door 2 is in the closed box 20 state, the angle between the door 2 and the limiting rib 11 is A0, that is, the maximum opening angle of the door 2 without the limiting component 3 is A0. After the limiting component 3 is installed, when the door 2 is in the closed box 20 state, the angle between the door 2 and the limiting surface 301 is A2 (corresponding to the maximum opening angle of the door 2 with the limiting component 3 installed), and the angle between the limiting surface 301 and the limiting rib 11 is A, where A0 = A + A2. Since A0 is a fixed value, when angle A increases, angle A2 will decrease accordingly, or when angle A decreases, angle A2 will increase accordingly. That is, the angle between the limiting surface 301 and the limiting rib 11 is inversely proportional to the maximum opening angle of the door 2 (with the limiting component 3 installed).

[0055] Therefore, the maximum opening angle of the door body 2 can be adjusted by adjusting the angle between the limiting surface 301 and the limiting rib 11, thereby reducing the difficulty of adjusting the maximum opening angle of the door body 2.

[0056] In some embodiments, the limiting member 3 includes a first limiting part 31. When the door body 2 abuts against the first limiting part 31, the door body 2 and the limiting rib 11 are spaced apart in the rotation direction of the door body 2. It can be understood that when the limiting member 3 includes the first limiting part 31, the door body 2 is adapted to open to abut against the first limiting part 31. At this time, the maximum opening angle of the door body 1 can be understood as the first angle (angle A1 as shown in Figure 8).

[0057] Therefore, when the door 2 abuts against the first limiting part 31, the maximum opening angle of the door 2 is less than that when the limiting part 3 is not installed. In this way, the maximum opening angle of the door 2 can be limited, thereby reducing the risk of the door 2 colliding with obstacles behind the door, and thus reducing the impact on the door 2, so as to protect the door 2.

[0058] In some embodiments, referring to Figure 10, the limiting member 3 further includes a second limiting part 32, which is detachably connected to the first limiting part 31. The door body 2 is adapted to open to abut against the second limiting part 32. As shown in Figure 11, when the door body 2 abuts against the second limiting part 32, the maximum opening angle of the door body 2 is a second angle (angle A2 in Figure 10), which is smaller than the first angle A1. Specifically, when the door body 2 abuts against the first limiting part 31, the maximum opening angle of the door body 2 is the first angle (angle A1 shown in Figure 8).

[0059] The first limiting part 31 and the second limiting part 32 can be connected by snap-fit, plug-in or magnetic attraction to reduce the difficulty of loading and unloading the first limiting part 31 and the second limiting part 32.

[0060] It is understandable that when the second limiting part 32 is connected to the first limiting part 31, the limiting surface 301 of the limiting member 3 is the surface of the second limiting part 32 away from the first limiting part 31. This is equivalent to increasing the angle between the limiting surface 301 and the limiting rib 11, thereby reducing the maximum opening angle of the door body 2.

[0061] Therefore, in scenarios where it is necessary to reduce the maximum opening angle of the door 2, the first limiting part 31 can be used alone, and in scenarios where it is necessary to further reduce the maximum opening angle of the door 2, the first limiting part 31 and the second limiting part 32 can be used in combination. In this way, the maximum opening angle of the door 2 can be further reduced to meet the user's needs.

[0062] For example, referring to Figures 6 and 7, when the door assembly 10 is not equipped with the limiting member 3, the door 2 is suitable to abut against the limiting rib 11 when the box 20 is opened. At this time, the maximum opening angle of the door 2 is A0, and A0 can be 130 degrees.

[0063] When the limiting member 3 is installed on the door assembly 10, and the limiting member 3 only includes the first limiting part 31, please refer to Figures 8 and 9. When the door 2 opens the box 20, it is suitable to abut against the first limiting part 31. At this time, the maximum opening angle of the door 2 is A1, and A1 can be 110 degrees.

[0064] When the limiting member 3 is installed on the door assembly 10, and the limiting member 3 includes a first limiting part 31 and a second limiting part 32, please refer to Figures 10 and 11. When the door 2 opens the box 20, it is suitable to abut against the second limiting part 32. At this time, the maximum opening angle of the door 2 is A2, which can be 90 degrees.

[0065] Thus, the first limiting part 31 and the second limiting part 32 can provide two maximum opening angles for the door assembly 10, and the first limiting part 31 and the second limiting part 32 are detachably connected, so that users can flexibly select the limiting part 3 according to actual usage needs to meet the user's usage needs.

[0066] It should be noted that the above-mentioned angle is only used as a preferred embodiment for illustration and does not represent a limitation thereof.

[0067] In some embodiments, multiple second limiting parts 32 are provided, and the multiple second limiting parts 32 are arranged sequentially in the rotation direction of the door body 2.

[0068] For example, three second limiting parts 32 may be provided, and the three second limiting parts 32 are stacked in sequence. Any two adjacent second limiting parts 32 can be detachably connected. Thus, by increasing or decreasing the number of second limiting parts 32, the angle between the limiting surface 301 and the limiting rib 11 can be adjusted, thereby adjusting the maximum opening angle of the door body 2.

[0069] In some embodiments, one of the first limiting portion 31 and the second limiting portion 32 is provided with a snap-fit ​​protrusion 321 and the other is provided with a snap-fit ​​groove 314, and the snap-fit ​​protrusion 321 and the snap-fit ​​groove 314 engage in a snap-fit ​​cooperation.

[0070] For example, referring to Figure 12, the first limiting part 31 is provided with a snap-fit ​​groove 314, and the second limiting part 32 is provided with a snap-fit ​​protrusion 321. The snap-fit ​​protrusion 321 engages with the snap-fit ​​groove 314. In this way, the first limiting part 31 and the second limiting part 32 can be detachably connected, and the snap-fit ​​engagement method is relatively simple, which helps to reduce the difficulty of connecting the first limiting part 31 and the second limiting part 32.

[0071] Of course, a snap-fit ​​protrusion can also be provided in the first limiting part 31 and a snap-fit ​​groove can be provided in the second limiting part 32 to achieve the same technical effect as described above, which will not be elaborated here.

[0072] In some embodiments, referring to FIG12, the first limiting portion 31 includes a first portion 311 and a second portion 312, the first portion 311 and the second portion 312 being detachably connected, and at least a portion of the mounting base 1 (the mounting base 1 in FIG3) is sandwiched between the first portion 311 and the second portion 312.

[0073] Therefore, the first part 311 and the second part 312 can be separated first, and a portion of the mounting base 1 can be placed between the first part 311 and the second part 312. Then, the first part 311 and the second part 312 can be connected to achieve the connection between the first limiting part 31 and the mounting base 1.

[0074] This reduces the difficulty of connecting the first limiting part 31 to the mounting base 1, and facilitates the installation and separation of the first limiting part 31 from the mounting base 1. This eliminates the need to disassemble the receiving device during the loading and unloading process of the limiting member 3, thereby reducing the difficulty of loading and unloading the limiting member 3 and improving the loading and unloading efficiency of the limiting member 3.

[0075] In some embodiments, the first part 311 and the second part 312 are connected by screws.

[0076] For example, as shown in Figure 12, both the first part 311 and the second part 312 are provided with mounting holes 313. When actually connected, the first part 311 and the second part 312 are first installed on both sides of the mounting base 1, and then the first part 311 and the second part 312 are connected by screws. This makes it easier to increase the connection strength of the first part 311 and the second part 312, thereby enhancing the connection strength between the first limiting part 31 and the mounting base 1. The bolt connection method is relatively simple and helps to reduce the connection difficulty.

[0077] In some embodiments, one of the limiting member 3 and the door body 2 is provided with a positioning protrusion 21 and the other is provided with a positioning groove 302, and the positioning protrusion 21 is adapted to be inserted into the positioning groove 302.

[0078] Please refer to Figures 9 and 11. The limiting member 3 is provided with a positioning groove 302, and the door body 2 is provided with a positioning protrusion 21. When the door body 2 and the limiting member 3 abut against each other, the positioning protrusion 21 is inserted into the positioning groove 302. In this way, the positioning cooperation between the door body 2 and the limiting member 3 can be achieved when the door body 2 abuts against the limiting member 3, thereby enhancing the stability of the door body 2 when it is open.

[0079] In some embodiments, as shown in Figures 2-4, the mounting base 1 is provided with a positioning part 12, and the limiting member 3 is adapted to be positioned and engaged with the positioning part 12.

[0080] Therefore, by setting the positioning part 12, the installation position of the limiting member 3 can be limited by the positioning part 12, thereby ensuring that the limiting member 3 can be assembled in place.

[0081] In some implementations, the positioning part 12 can be a positioning rib, and the limiting member 3 is adapted to abut against the positioning rib. This makes it easy to limit the installation position of the limiting member 3 by the positioning rib, thereby ensuring that the limiting member 3 can be assembled in place.

[0082] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0083] Therefore, the door assembly disclosed herein can reduce the risk of collision between the door and obstacles behind it, thereby reducing the impact on the door and protecting it.

[0084] The accommodating device disclosed herein has the same advantages as the aforementioned door assembly over related technologies, and will not be repeated here.

[0085] The above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit it. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
