[0042] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0044] In the prior art, to improve indoor air quality, a filter is typically installed in the indoor unit of an air conditioner. The filter filters the air flowing through the indoor unit, thereby improving indoor air quality. Furthermore, to facilitate installation and removal of the filter, a slide rail is provided on the indoor unit casing. To install the filter, the filter can be first mounted on the slide rail, then slid into the indoor unit to complete the installation. To remove the filter, the filter can be pulled out of the indoor unit using the slide rail, and then removed from the slide rail to complete the removal.

[0045] However, existing indoor unit casings are typically curved, and therefore the slide rails are also curved. Consequently, after the filter is installed in the indoor unit via the slide rails, it becomes curved. Over time, the filter can become deformed, making it difficult to remove and install, and thus reducing the user experience.

[0046] like Figures 1 to 8 As shown, the embodiment of the present disclosure provides a refrigeration device that can quickly install or remove the filter assembly 20 without providing an arc-shaped slide rail structure on the indoor unit, thereby avoiding deformation of the filter assembly 20 and improving the user experience.

[0047] like Figures 1 to 8 As shown, an embodiment of the present disclosure provides a refrigeration device including: a filter assembly 20 and a casing 10. The filter assembly 20 includes a mounting frame 21, and the side wall surface of the mounting frame 21 is provided with a mounting protrusion 211 and a limiting portion, and the mounting protrusion 211 and the limiting portion are respectively provided at both ends of the side wall surface of the mounting frame 21; the mounting area of the casing 10 is used to mount the filter assembly 20, and the side wall surface of the mounting area is provided with a mounting groove 12 and a limiting matching portion 13 corresponding to the mounting protrusion 211 and the limiting portion, respectively; wherein the limiting matching portion 13 can move in a direction close to or away from the filter assembly 20; the mounting protrusion 211 of the mounting frame 21 can be mounted in the mounting groove 12, and the limiting portion is placed in a position corresponding to the limiting matching portion 13, at which time the limiting matching portion 13 abuts against the limiting portion to mount the filter assembly 20 in the mounting area.

[0048] Specifically, the refrigeration equipment also includes a heat exchanger, and the mounting area is located at a position corresponding to the heat exchanger. The filter assembly 20 also includes a filter body 22, which is fixedly mounted to the mounting frame 21. The mounting groove is located on the side of the mounting protrusion 211 away from the retaining portion 13, and the retaining portion 13 is located on the side of the retaining portion away from the mounting groove. The mounting groove is provided with an opening, and the mounting opening is located on the side near the mounting protrusion 211.

[0049] When installing the filter assembly 20, the mounting protrusion 211 can be first installed in the mounting groove 12 through the opening. The mounting groove 12 can limit the mounting protrusion 211 to secure one side of the filter assembly 20. After securing one side of the filter assembly 20, the side of the mounting frame 21 provided with the limiting portion can be pushed toward the limiting mating portion 13. At this time, the mounting frame 21 can push the limiting mating portion 13 away from the filter assembly 20, causing the limiting mating portion 13 to give way. After the mounting frame 21 moves to the installation area, the limiting mating portion 13 moves toward the mounting frame 21 and abuts against the limiting portion, preventing the filter assembly 20 from falling out of the installation area.

[0050] To remove the filter assembly 20, first move the retaining member 13 away from the mounting frame 21 to free it from the retaining member. Then, remove the side of the mounting frame 21 where the retaining member is located from the mounting area. After removing one side of the mounting frame 21, remove the mounting protrusion 211 from the mounting slot 12 through the opening, removing the entire mounting frame 21 from the mounting area.

[0051] With such a configuration, the filter assembly 20 can be quickly installed or removed without providing an arc-shaped slide rail structure on the indoor unit, thereby avoiding deformation of the filter assembly 20 and improving the user experience.

[0052] like Figure 2 and Figure 7 As shown, optionally, the left and right sidewalls of the mounting frame 21 are provided with mounting protrusions 211 and position-limiting portions, and the left and right sidewalls of the mounting area are also provided with mounting grooves 12 and position-limiting mating portions 13. This arrangement can further prevent the filter assembly 20 from falling off the mounting area.

[0053] Optionally, the filter body 22 can be detachably mounted on the mounting frame 21. For example, the filter can be mounted on the mounting frame 21 by snapping, gluing, or screwing. Thus, after the filter assembly 20 is removed from the mounting area, the filter body 22 can be removed from the mounting frame 21 for replacement or cleaning.

[0054] like Figure 1 As shown, the filter assembly 20 is optionally provided with multiple filter bodies 22 and mounting frames 21. It is understood that a general air conditioner indoor unit is provided with multiple indoor heat exchangers, some of which are arranged at an angle and some of which are arranged vertically to increase the efficiency of indoor cooling or heating. The multiple filter bodies 22 and mounting frames 21 of the filter assembly 20 are installed in a manner corresponding to the multiple indoor heat exchangers. In this way, the air flowing through the indoor heat exchanger can be fully filtered to further improve the indoor air quality.

[0055] like Figure 4 As shown, in some embodiments, the position-limiting fitting portion 13 is an elastic structure, and when the position-limiting fitting portion 13 is in a natural state, the position-limiting fitting portion 13 can abut against the position-limiting portion.

[0056] Specifically, when installing the filter assembly 20, the mounting frame pushes the retaining portion 13 away from the mounting frame, compressing it. After the filter assembly 20 is installed, the retaining portion 13, under the action of elastic force, moves toward the mounting frame 21 and abuts against the retaining portion. This arrangement makes it easier for users to install the filter assembly 20, further enhancing the user experience.

[0057] like Figure 4 As shown, in some embodiments, a side wall surface of the installation area is provided with an avoidance opening 14; the limiting fitting portion 13 includes a connecting piece 131 and a limiting protrusion 132; wherein, the connecting piece 131 is elastically connected to the edge of the avoidance opening 14, and the limiting protrusion 132 is provided on the side of the connecting piece 131 facing the limiting portion.

[0058] Specifically, a clearance opening 14 is provided on the sidewall of the mounting area at a position corresponding to the stopper. A first side of a connecting piece 131 is elastically connected to the edge of the clearance opening 14, and a second side of the connecting piece 131 extends away from the connection. A limiting protrusion 132 is provided on the second side of the connecting piece 131, facing the stopper. The limiting protrusion 132 has an inclined surface.

[0059] When installing the filter assembly 20, the mounting frame 21 can abut against the inclined surface of the limiting protrusion 132, pushing the limiting protrusion 132 away from the mounting frame 21, thereby causing the connecting piece 131 to bend. After the filter assembly 20 is installed, the connecting piece 131, under the action of the elastic force, can drive the limiting protrusion 132 to move toward the mounting frame 21, so that the limiting protrusion 132 abuts against the limiting portion.

[0060] like Figure 5 and Figure 6 As shown, in some embodiments, a limiting block 212 is provided on the side wall surface of the mounting frame 21 to constitute a limiting portion, and a limiting groove 213 is provided on the side wall surface of the limiting block 212 facing away from the mounting frame 21; wherein, the limiting protrusion 132 can be engaged with or disengaged from the limiting groove 213.

[0061] Specifically, when the filter assembly 20 is installed in the installation area, the limiting protrusion 132 can abut against the limiting block 212 to limit the filter assembly 20 .

[0062] When the filter assembly 20 is installed vertically, the stopper 212 pushes the stopper protrusion 132 away from the mounting frame 21. After the filter assembly 20 is installed, the stopper 212 moves into the stopper groove 213 and engages with the stopper groove 213. At this point, the stopper 212 abuts against the sidewall of the stopper groove 213 to prevent the filter assembly 20 from shaking.

[0063] like Figure 2 As shown, in some embodiments, the housing 10 is further provided with a support surface 15 for supporting the filter assembly 20 .

[0064] Specifically, the bottom wall surface of the installation area constitutes the support surface 15. In this way, after the filter assembly 20 is installed, the support surface can abut against the lower edge of the filter assembly 20 to support the filter assembly 20.

[0065] like Figure 4 As shown, optionally, the housing 10 is further provided with a support member 16 , and the support member 16 is provided with a support surface.

[0066] Specifically, a support member 16 is provided in the middle of the side wall of the installation area, and the upper end surface of the support member 16 forms the support surface 15. When the filter assembly 20 is installed in the upper half of the installation area, the upper end surface of the support member 16 can abut against the lower edge of the filter assembly 20 to provide support for the filter assembly 20.

[0067] like Figure 1 and Figure 2 As shown, in some embodiments, the refrigeration equipment is provided with a plurality of filter assemblies 20; a crossbeam 11 is provided in the installation area to divide the installation area into a plurality of sub-installation areas, and the number of sub-installation areas is the same as the number of the filter assemblies 20; wherein the crossbeam 11 is provided with a mounting groove 12 and a limiting fitting portion 13, and the mounting frame 21 is provided with a mounting protrusion 211 and a limiting portion corresponding to the crossbeam 11.

[0068] Specifically, the ends of the crossbeam 11 are connected to the top and bottom walls of the installation area, respectively, to divide the installation area into multiple self-installation areas. Both sides of the crossbeam 11 are provided with mounting grooves 12, and the mounting protrusions 211 of the mounting frames 21 on either side of the crossbeam 11 can be respectively installed in the mounting grooves 12 on either side of the crossbeam 11. The crossbeam 11 is also provided with position-limiting mating portions 13 on both sides of the crossbeam 11 to limit the position of the position-limiting portions of the mounting frames 21 on either side of the crossbeam 11.

[0069] In practice, a clearance opening 14 is provided through the crossbeam 11 at the position corresponding to the stop portion. A connecting piece 131 is provided at the clearance opening 14, and limiting protrusions 132 are provided on both sides of the connecting piece 131. When the first and second filter assemblies 20 are installed on either side of the crossbeam 11, the user can first install the first filter assembly 20. The user can then cause the first mounting frame 21 to push the limiting protrusion 132 through the clearance opening 14 to the other side of the crossbeam 11, bending the connecting piece 131. After the first filter assembly 20 is installed, the connecting piece 131 returns to its natural position and drives the limiting protrusion 132 to limit the stop portion of the first mounting frame 21. When installing the second filter assembly 20, the user can cause the second mounting frame 21 to push the limiting protrusion 132 through the clearance opening 14 into the limiting groove 213 of the limiting block 212 of the first mounting frame 21, bending the connecting piece 131. After the second filter assembly 20 is installed, the connecting piece 131 returns to its natural state and drives the limiting protrusion 132 to limit the limiting parts of the first installation frame 21 and the second installation frame 21 at the same time.

[0070] In some embodiments, a plurality of mounting protrusions 211 are provided on the sidewall surface of the mounting frame 21 , and a plurality of mounting grooves 12 are correspondingly provided on the sidewall surface of the mounting area.

[0071] Specifically, the plurality of mounting protrusions 211 of the mounting frame 21 can be respectively mounted in the plurality of mounting grooves 12 on the sidewall surface of the mounting area. This arrangement can further improve the stability of the mounting frame 21 installation to prevent the filter assembly 20 from falling out of the mounting area.

[0072] In some embodiments, a plurality of position-limiting portions are provided on the sidewall surface of the mounting frame 21 , and a plurality of position-limiting matching portions 13 are correspondingly provided on the sidewall surface of the mounting area.

[0073] Specifically, the multiple limiting matching parts 13 on the side wall of the installation area can respectively limit the multiple limiting parts of the installation frame 21. This arrangement can further improve the stability of the installation of the installation frame 21 to prevent the filter assembly 20 from falling out of the installation area.

[0074] Optionally, when the mounting protrusion 211 is mounted in the mounting groove 12, the distance between the mounting protrusion 211 and the side wall of the mounting groove 12 is a first distance t. The first distance t is greater than or equal to 0.2 cm and less than or equal to 0.1 cm.

[0075] Optionally, the longitudinal section of the mounting protrusion 211 is circular, and the radius of the longitudinal section of the mounting protrusion 211 is a first radius R. The distance between the two sidewalls of the mounting groove 12 is a first distance H, where H=2R+2t.

[0076] Optionally, the thickness of the supporting surface of the supporting member is a first thickness T. The first thickness T is less than or equal to 0.2 cm.

[0077] Optionally, the distance between the opening of the installation groove 12 and the innermost sidewall surface of the installation protrusion 211 in the installation groove 12 is a second distance L, wherein R≤L≤R+T.

[0078] like Figure 7 and Figure 8 As shown, in some embodiments, the refrigeration device further includes: a panel 30 and a detection device 40. The panel 30 is located outside the installation area; the detection device 40 is electrically connected to the refrigeration system and is used to obtain the installation status of the filter assembly 20. When the detection device 40 determines that the panel 30 is open, the detection device 40 controls the refrigeration device to stop operating.

[0079] Specifically, the detection device 40 can be provided on the filter assembly 20 , the housing 10 or the panel 30 . The panel 30 includes a pivoting side that is rotatably connected to the housing 10 .

[0080] After the filter assembly 20 is installed, the panel 30 can be rotated about its pivoting side toward the installation area to engage with the outside of the installation area to protect the internal components of the refrigeration unit. If the user needs to remove the filter assembly 20, the panel 30 can be rotated about its pivoting side away from the installation area to open the installation area, and then the filter assembly 20 can be removed from the installation area.

[0081] The refrigeration device further comprises a refrigeration system, and the detection device 40 is electrically connected to the refrigeration system. When the detection device 40 detects that the panel 30 opens the installation area, the detection device 40 can shut down the refrigeration system to avoid potential safety hazards.

[0082] like Figure 7 and Figure 8 As shown, in some embodiments, the detection device 40 includes: a control unit, a conductive sheet 41, and a detection sheet 42. The conductive sheet 41 is elastically mounted on the filter assembly 20 or the housing 10; the detection sheet 42 is mounted on the filter assembly 20 or the housing 10, and is located on the side of the conductive sheet 41 facing away from the panel 30. When the panel 30 is opened, the conductive sheet 41 is separated from the detection sheet 42, and the control unit controls the refrigeration equipment to stop operating.

[0083] Specifically, the control unit is electrically connected to the refrigeration system, and the conductive sheet 41 and detection sheet 42 are each connected to the control unit. Both the conductive sheet 41 and detection sheet 42 are made of conductive materials. Extrusion blocks 31 are located on the panel 30 at positions corresponding to the conductive sheet 41. The conductive sheet 41 has an elastic structure, and when the conductive sheet 41 is in its natural state, a predetermined distance exists between the conductive sheet 41 and the detection sheet 42.

[0084] When the panel 30 is fastened to the mounting area, the pressing block 31 pushes the conductive sheet 41 to contact the detection sheet 42, thereby forming a circuit between the control unit, the conductive sheet 41, and the detection sheet 42. At this point, the control unit determines that the panel 30 is in the fastened state.

[0085] like Figure 7 and Figure 8 As shown, when the panel 30 is opened, the conductive sheet 41 is separated from the detection sheet 42 by the elastic force, so that a circuit is formed between the conductive sheet 41 and the detection sheet 42. At this time, the control unit determines that the panel 30 is in the open state.

[0086] The above description and the accompanying drawings sufficiently illustrate the embodiments disclosed in this application to enable those skilled in the art to practice them.
