[0003] In the process of implementing this application, the inventors found that there are at least the following problems in the prior art:

[0004] The cover is fixed to the main housing by multiple screws, which makes disassembly and assembly inconvenient. Take the housing of an air conditioner as an example. When in use, the cover faces downward. When internal parts are replaced during after-sales maintenance, the cover needs to be removed. When removing and installing the cover, one needs to hold the cover with one hand while removing the screws on the cover with the other hand. This operation is time-consuming and laborious. In addition, a large number of screws are required during disassembly and assembly, which requires a correspondingly long assembly time. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide an air-conditioning device and a device housing, the structural design of which can effectively solve the problem of time-consuming and labor-intensive assembly and disassembly of the cover.

[0033] The utility model discloses an air conditioning device and a device shell, which can be disassembled and assembled by a convenient noodle cover.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] The device housing provided in the present application, including but not limited to the device housing of air-conditioning equipment, is particularly suitable for equipment that is installed with the cover facing downward when in use.

[0036] In some embodiments, see Figure 1-Figure 3The device housing provided by the utility model includes a cover 1 and a main housing 2. The cover 1 is used to be installed on the main housing 2. Specifically, a window can be provided on the main housing 2. The cover 1 is used to close the window to play a protective role. Alternatively, the cover 1 can also be installed on the main housing 2 to play a decorative role. Whether the window is provided on the main housing 2 is not limited. The cover 1 includes a cover body 11 and at least one buckle 12 provided on the cover body 11. The shape and size of the cover body 11 can be set as required. No specific limitation is made here. In the case where a window is provided on the main housing 2, the shape and size of the cover body 11 are set according to the shape and size of the window. At least one card slot 21 is provided on the main housing 2 corresponding to the buckle 12. Specifically, the buckle 12 corresponds to the card slot 21 one by one. The buckle 12 and the corresponding card slot 21 form a group of snap-fit ​​structures. According to the size of the cover 1, the number of snap-fit ​​structures can be set to one group, two groups or more groups. The length of the slot 21 is greater than the length of the corresponding buckle 12. The buckle 12 can be inserted into the slot 21 from the first end 211 of the corresponding slot 21 and slide along the slot 21 to its second end 212, that is, the first end 211 corresponds to the disassembly position of the face cover 1, and the second end 212 corresponds to the fixed position of the face cover 1. When the buckle 12 is located at the second end 212 of the corresponding slot 21, the buckle 12 cooperates with the slot 21 to achieve reverse engagement in the insertion direction, that is, longitudinal engagement, thereby preventing the buckle 12 from falling out of the second end 212. The width of the second end 212 of at least one slot 21 is less than the width of the first end 211, that is, the second end 212 of at least one slot 21 is designed to be narrowed. It can be understood that the width mentioned here and below refers to the lateral width, which is the direction perpendicular to the above-mentioned insertion direction, and the lateral is perpendicular to the above-mentioned sliding direction.

[0037] When the device housing provided by the utility model is used and the face cover 1 is installed, the buckle 12 is first inserted into the card slot 21 from the first end 211 corresponding to the card slot 21, and then the face cover 1 is pushed to move relative to the main housing 2, so that the buckle 12 slides along the card slot 21. When the face cover 1 is pushed to the bottom, that is, when the buckle 12 moves to the second end 212 of the card slot 21, the reverse engagement in the insertion direction is achieved, so that the buckle 12 cannot be disengaged from the second end 212, and the face cover 1 is connected to the main housing 2. When disassembling, the face cover 1 is pushed in the reverse direction from the second end 212 to the first end 211, and the engagement is released. When the face cover 1 is pulled by an external force or under the action of the face cover 1's own gravity, the buckle 12 can be disengaged from the first end 211, so that the face cover 1 is disassembled. In summary, the device housing provided by the present application and the face cover 1 are easy to disassemble and assemble, saving time and effort. The width of the second end 212 of the slot 21 is smaller than the width of the first end 211. On the one hand, the buckle 12 can be conveniently inserted from the first end 211. On the other hand, the buckle 12 can be longitudinally engaged at the second end 212 and can also limit the buckle 12 in the horizontal direction to prevent the cover 1 from being displaced laterally relative to the main housing 2 to generate abnormal noise and vibration. In addition, the device housing does not need to be provided with multiple screws to connect the cover 1 to the main housing 2, thereby reducing the number of materials and further reducing the assembly time.

[0038] In some embodiments, the width of the second end 212 of at least one slot 21 is 0.4 to 0.6 mm greater than the thickness of the corresponding buckle 12. It is understandable that the thickness of the buckle 12 is the thickness in the above-mentioned lateral direction. As configured above, the buckle 12 can smoothly move into the second end 212 of the slot 21, while also preventing the lower cover 1 from being greatly displaced laterally when the buckle 12 is engaged with the slot 21, thereby generating abnormal noise and vibration. Specifically, the width of the second end 212 of at least one slot 21 is 0.5 mm greater than the thickness of the corresponding buckle 12. Considering the processing error, the above values ​​can be set accordingly according to the size of the cover 1 and the size of the buckle 12. For example, for a small device housing, the above values ​​can be correspondingly smaller.

[0039] Specifically, the device housing is provided with two sets of snap-fit ​​structures, and the width of the second end 212 of the slot 21 in one set of snap-fit ​​structures is smaller than the width of the first end 211; or, the device housing is provided with multiple sets of snap-fit ​​structures, and the width of the second end 212 of the slot 21 in two sets of snap-fit ​​structures is smaller than the width of the first end 211. As set above, the above-mentioned limiting effect can be achieved, and at the same time, only part of the slot 21 is narrowed, which reduces the requirements for the processing accuracy of the buckle 12 and the slot 21, and reduces the risk that the buckle 12 cannot be inserted into the second end 212 of the slot 21 and cannot be engaged when the cover 1 is installed due to insufficient processing accuracy of the buckle 12 or the slot 21 or deformation of the buckle 12 or the slot 21 during transportation and assembly.

[0040] For example, two rows of buckles 12 are respectively arranged on the cover body 11 along its extension direction, and the two rows of buckles 12 are respectively arranged on the edges of the two opposite sides of the cover body 11. Each row is specifically provided with five buckles 12, and the two corresponding slots 21 in one row of buckles 12 are set so that the width of the second end 212 is smaller than the width of the first end 211, and specifically, the slots 21 corresponding to the first buckle 12 and the fourth buckle 12 from one end of one row of buckles 12 are set so that the width of the second end 212 is smaller than the width of the first end 211.

[0041] In some embodiments, see Figure 4-Figure 6 The buckle 12 includes a main body 121 connected to the face cover body 11 and an arm 122 protruding from the main body 121, and the arm 122 is used to abut against the main shell 2 for engagement. It can be understood that the main body 121 and the arm 122 can be an integrated structure or a split structure connected by a conventional fixing method. When the buckle 12 slides to the second end 212 of the slot 21, the main body 121 is inserted into the slot 21, and the arm 122 can abut against the inner wall of the main shell 2 next to the notch of the slot 21, so that the face cover 1 and the main shell 2 are limited in the longitudinal direction to achieve longitudinal engagement. As set above, the slot 21 can be a through hole opened on the main shell 2, and the structure is simple.

[0042] Furthermore, the side of the support arm 122 that abuts against the main housing 2 for engagement is tilted in the direction from the first end 211 to the second end 212 away from the cover body 11. That is, the side of the support arm 122 that abuts against the main housing 2 to achieve the above-mentioned longitudinal engagement, thereby preventing the buckle 12 from slipping out of the second end 212, is tilted. By tilting the side of the support arm 122 opposite to the cover body 11 so that the support arm 122 is gradually thinned in the direction from the first end 211 to the second end 212, the above-mentioned engagement effect can be achieved, and at the same time, the requirements for the processing accuracy of the buckle 12 are reduced, thereby reducing the risk that the buckle 12 cannot be engaged when the cover 1 is installed due to insufficient processing accuracy of the buckle 12 or deformation of the buckle 12 during transportation and assembly.

[0043] In some embodiments, see Figure 7 , the device housing also includes a fastener 3, which is used to fix the face cover body 11 to the main housing 2. During disassembly, first release the fastener 3 from fixing the face cover body 11 and the main housing 2, and then move the face cover body 11 relative to the main housing 2, so that the buckle 12 moves from the second end 212 of the card slot 21 to the first end 211, and then the buckle 12 can be disengaged from the card slot 21, completing the disassembly of the face cover 1. During installation, the buckle 12 is also first engaged with the card slot 21, and then the fastener 3 is fastened. In summary, by setting the fastener 3 to fix the face cover body 11 to the main housing 2, a reliable connection between the two is guaranteed. And due to the engagement of the buckle 12 during disassembly and assembly, there is no need to hold the face cover body 11 with one hand, so that disassembly and assembly are more convenient.

[0044] In some embodiments, see Figure 4-Figure 6 , a fixing hole 111 is provided on the face cover body 11, and a screw hole is provided on the main shell 2 corresponding to the fixing hole 111. When the buckle 12 slides to the second end 212, the screw hole is opposite to the fixing hole 111, and the fastener 3 includes a screw that matches the screw hole. That is, the fastener 3 adopts a screw, which is reliable in connection and convenient for disassembly and assembly. The specific screw can be a hand screw, so as to facilitate manual disassembly and assembly without the need for tools. When it is necessary to explain, the screw hole can be directly opened on the main shell 2, or a stud can be provided in the main shell 2, and a screw hole can be opened on the stud. During installation, first install the buckle 12 of the face cover 1 into the corresponding slot 21, and then move the face cover 1 to one side to the bottom, and see that the fixing hole 111 of the face cover 1 corresponds to the corresponding screw hole. At this time, the buckle 12 is engaged with the slot 21, and then the fixing hole 111 and the screw hole can be locked with screws.

[0045] In some embodiments, see Figure 4-Figure 6 The front of the cover body 11 is provided with a groove to form a hand-holding position 112 for user operation, and the buckle 12 is provided on the back of the cover body 11. By providing a groove to form the hand-holding position 112, the user can buckle the hand-holding position 112 when pushing the cover body 11, which further facilitates the user's operation. Specifically, the hand-holding positions 112 are respectively provided at the opposite ends of the cover body 11, and force can be applied from both ends during operation.

[0046] In some embodiments, the fastener 3 is disposed at the buckle position 112 to fix the cover body 11 to the main housing 2. When the fastener 3 is a screw, the corresponding fixing hole 111 is provided at the bottom of the groove. In this way, the fastener 3 can be sunk below the outer surface of the cover 1, the overall structure is neater and more beautiful, and the fastener 3 is not easily knocked off by an external force.

[0047] Specifically, a screw hole is provided at the bottom of the groove, and the face cover body 11 is connected to the main shell 2 by screws. When the device shell is in use and the face cover 1 is facing upward, when disassembling, you only need to unscrew the screws in the fixing hole 111 by hand, and then put both hands into the hand-holding positions 112 respectively, and move the face cover 1 horizontally, such as moving it horizontally to the right, so that the buckle 12 moves to the first end 211 of the slot 21, and then the buckle 12 falls out of the slot 21 due to gravity, and the face cover 1 is removed from the main shell 2, and the installation and disassembly method is simpler.

[0048] In some embodiments, the back of the cover body 11 is provided with reinforcing ribs 13 along the extension direction of the cover body 11. The back of the cover body 11 may be provided with a raised structure, i.e., reinforcing ribs 13, to increase the strength of the cover body 11 and prevent the cover body 11 from bending and deformation.

[0049] In some embodiments, at least one of the two opposite side walls of at least one of the slots 21 is provided with a limiting protrusion, and the limiting protrusion is used to abut against the side wall of the buckle 12 to limit the buckle 12 at the second end 212. It should be noted that the two opposite side walls of the slot 21 refer to two side walls extending in the sliding direction and arranged opposite to each other, and at least one of the two is provided with a limiting protrusion protruding toward the other, that is, at least one side wall of the slot 21 extending in the sliding direction is provided with a limiting protrusion, and the buckle 12 slides along the slot 21 until it passes over the limiting protrusion and enters the second end 212. In the above embodiment, the fastener 3 fixedly connects the cover body 11 with the main housing 2. The difference between this embodiment and the above embodiment is that a limiting protrusion is provided on the side wall of the slot 21 to limit the buckle 12 to the second end 212 of the slot 21, thereby realizing the limitation of the sliding direction of the buckle 12. Then, combined with the longitudinal engagement of the buckle 12 with the slot 21 and the lateral limitation of the buckle 12 by the second end 212, the freedom of the buckle 12 in six directions is limited, thereby realizing the reliable connection between the cover body 11 and the main housing 2. In this embodiment, the connection reliability can be guaranteed without the fastener 3. It can be understood that at least part of the limiting protrusion and / or at least part of the buckle 12 are elastic, so that the buckle 12 can pass over the limiting protrusion by its own deformation or the limiting protrusion under the action of external force. Of course, after the buckle 12 passes over the limiting protrusion, the deformation of the limiting protrusion and / or the buckle 12 is automatically restored, thereby realizing the effective limitation of the buckle 12. By providing a limiting protrusion for limiting the position, it is possible to achieve reliable limiting of the buckle 12 and provide an obvious operating feel when the user pushes the face cover 1 to engage the buckle 12 with the slot 21 .

[0050] Furthermore, the distance between the limiting protrusion and the end surface of the second end 212 of the slot 21 is consistent with the length of the corresponding position of the buckle 12 to limit the sliding of the buckle 12. Since the distance between the end surface of the second end 212 and the limiting protrusion is consistent with the width of the buckle 12, the front end surface of the buckle 12 along the sliding direction abuts against the end surface of the second end 212 of the slot 21, and the rear end surface abuts against the side of the limiting protrusion, so that the buckle 12 is reliably limited, that is, the sliding of the buckle 12 along the slot 21 is limited, and the longitudinal direction of the buckle 12 is also limited, that is, the buckle 12 is effectively limited at the second end 212 of the slot 21.

[0051] Specifically, the limiting protrusion is part of the side wall of the slot 21, that is, an integrated structure, which is easy to form. Alternatively, the limiting protrusion can also be an elastic protrusion slidably mounted on the side wall of the slot 21, and an elastic member is arranged therewith, and when the buckle 12 rotates along the slot 21 toward the second end 212, it can push the limiting protrusion to compress the elastic member and retract, and when the buckle 12 slides to the second end 212, the buckle 12 releases the effect on the limiting protrusion, and the limiting protrusion is automatically lifted and reset under the action of the resetting force of the elastic member, so as to limit the buckle 12 to the second end 212. As set above, when the user pushes the cover body 11 to make the buckle 12 engage with the slot 21, the limiting protrusion is lifted and a sound prompt such as a click sound can be provided, so that the user can confirm that the cover body is installed in place.

[0052] In other embodiments, the size of the second end 212 of the slot 21 may be set smaller than the size of the first end 211 to achieve an interference fit with the buckle 12, thereby achieving a reliable connection between the cover body 11 and the main shell 2.

[0053] Based on the device housing provided in the above embodiments, the utility model also provides an air conditioning device, which includes any device housing in the above embodiments. Since the air conditioning device adopts the device housing in the above embodiments, please refer to the above embodiments for the beneficial effects of the air conditioning device.

[0054] Specifically, the air conditioning device is a duct air conditioner, including a device housing and a fan, a heat exchanger, a PTC (Positive Temperature Coefficient, positive temperature coefficient thermistor) and the like arranged in the device housing, and a fresh air chamber is formed on one side of the device housing. When the cover 1 is disassembled, the cover body 11 can be moved toward the fresh air chamber.

[0055] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
