[0039] The air conditioning device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0040] like Figures 1-4 As shown, the air conditioning device 100 according to the embodiment of the present invention includes a housing assembly 1 , a heat exchanger 2 and an air supply fan 3 .

[0041] The shell assembly 1 includes a first shell 11, which defines a accommodating cavity 110. The first shell 11 also includes an air inlet 111 and an air outlet 112. The air inlet 111 is distributed along the circumference of the surrounding wall 115 of the first shell 11. That is, the first shell 11 discharges air into the room along the circumference of the surrounding wall 115, so that the air-conditioning equipment of this embodiment supplies air to the room more evenly, makes the indoor temperature rise or fall more evenly, and improves the user experience.

[0042] The air outlet 112 is provided at the bottom 113 of the first shell 11. The air inlet 111 and the air outlet 112 are both connected to the accommodating cavity 110. A first platform 114 for placing objects is formed on the top of the first shell 11, so that the first shell 11 forms a structure capable of placing objects.

[0043] Heat exchanger 2 is disposed within chamber 110 and is configured to exchange heat with air entering chamber 110 through air inlet 111. Air blower 3 is disposed within chamber 110 and is located inside heat exchanger 2. Air blower 3 is configured to force air within chamber 110 toward air outlet 112.

[0044] The blower 3 generates negative pressure in the accommodating chamber 110, and indoor air is drawn into the accommodating chamber 110 through the air inlet 111. The air exchanges heat with the heat exchanger 2 as it passes through the heat exchanger 2, causing the drawn-in air to be heated or cooled. The heated or cooled air is then blown into the room through the air outlet 112, thereby improving the indoor temperature and providing comfort to the user.

[0045] Compared to related art, the air conditioning device 100 of the present embodiment not only draws indoor air into the accommodating chamber 110 via the air supply fan 3 and exchanges heat with the heat exchanger 2, but also blows the heated or cooled air into the room, thereby improving the indoor temperature and achieving the purpose of making the user's living comfortable. Furthermore, the top of the first housing 11 has a first platform 114 for storing items, allowing the air conditioning device 100 of this embodiment to also function as other indoor storage structures, such as a desk or coffee table. This improves the home decoration integration of the air conditioning device 100 of the present embodiment and enhances the user experience.

[0046] In addition, by arranging circumferentially distributed air outlets 112 on the surrounding wall 115 and a heat exchanger 2 cooperating with the air outlets 112, the air-conditioning equipment of this embodiment can supply air to the room more evenly, so that the room can be heated or cooled more evenly, thereby improving the comfort of the indoor environment and providing the user with a better experience.

[0047] In some optional embodiments, such as Figure 1 As shown, the air supply fan 3 is an axial flow fan.

[0048] In some embodiments, as Figure 1 As shown, the surrounding wall 115 includes a plurality of side walls 1151 sequentially connected in its circumferential direction; each side wall 1151 is provided with a through hole 1152 , and the through hole 1152 is communicated with the accommodating cavity 110 , and the plurality of through holes 1152 form an air outlet 112 .

[0049] The heat exchanger 2 includes a plurality of heat exchange parts 21 , which are spaced apart in the circumferential direction of the surrounding wall 115 , and the plurality of heat exchange parts 21 correspond one-to-one to the plurality of through holes 1152 , and the air supply fan 3 is located inside the plurality of heat exchange parts 21 .

[0050] For example, the surrounding wall 115 has four side walls 1151 connected in sequence in its axial direction. The first housing 11 is a rectangular parallelepiped. Each of the four side walls 1151 is provided with a through hole 1152 that communicates with the accommodating cavity 110. The heat exchanger 2 includes four heat exchange portions 21, each corresponding to one of the four through holes 1152.

[0051] After the air supply fan 3 draws indoor air into the accommodating chamber 110, the air first exchanges heat with each of the multiple heat exchange components 21 before being discharged from the multiple air outlets 112. Before being blown out of the multiple air outlets 112, the air is fully in contact with the multiple heat exchange components 21, making the airflow from the multiple air outlets 112 more uniform in temperature and improving the comfort of the indoor environment.

[0052] In some embodiments, as Figure 2-Figure 5 As shown, the air conditioning device 100 of the embodiment of the present invention further includes a second shell 12, a plurality of second shells 12, and a second platform 121 for placing objects is formed on the top of the second shell 12, so that the first shell 11 forms a structure capable of placing objects.

[0053] The second shell 12 has an air outlet channel 122 running through it, and the air outlet channel 122 includes an air inlet end 1221 and an air outlet end 1222. Each second shell 12 can be detachably matched with multiple side walls 1151 in a one-to-one correspondence, wherein the multiple air inlet ends 1221 are connected to the multiple through holes 1152 in a one-to-one correspondence.

[0054] Specifically, if Figure 2-Figure 4 As shown, the first housing 11 includes two side walls 1151 that oppose each other in its longitudinal direction, each of which is provided with an air inlet 111. There are two second housings 12. One second housing 12 mates with one side wall 1151, and the air inlet end 1221 of the air outlet channel 122 of the first second housing 12 is connected to the air inlet 111 of the first side wall 1151. The other second housing 12 mates with the other side wall 1151, and the air inlet end 1221 of the air outlet channel 122 of the second second housing 12 is connected to the air inlet 111 of the other side wall 1151.

[0055] The air conditioning device 100 of this embodiment includes a first shell 11 and multiple second shells 12, so that the air conditioning device 100 of this embodiment can freely combine the first shell 11 and multiple second shells 12 according to the user's home decoration needs to form a storage structure, thereby further improving the user's experience.

[0056] Each second shell 12 has an air outlet channel 122 connected to the air outlet 112, so that the air flow blown out from the multiple air outlets 112 of the first shell 11 can be evenly blown into the indoor area from the circumference of the air-conditioning device 100 of this embodiment through the air outlet channels 122 of the multiple second shells 12, thereby eliminating the need to change the specifications of the heat exchanger 2 and the fan, and realizing modular coordination of the first shell 11 and the second shell 12.

[0057] In some optional embodiments, such as Figure 2-Figure 4As shown, the first shell 11 and the second shell 12 are both rectangular, and the two second shells 12 are respectively matched on both sides of the first shell 11 to form a rectangular storage structure.

[0058] In other optional embodiments, such as Figure 5 As shown, the first shell 11 is cylindrical, each of the multiple second shells 12 is fan-shaped, and the multiple second shells 12 are fitted on the outer circumference of the first shell 11. The multiple second shells 12 and the first shell 11 are combined into a cylindrical storage structure.

[0059] Furthermore, one of a plug-in connector and a plug-in slot is provided on the side wall 1151 of each second housing 12 , and the other of a plug-in connector and a plug-in slot is provided on each side surface, and the plug-in connector and the plug-in slot are capable of matching.

[0060] In other words, a plug-in component is provided on the side wall 1151 of each second shell 12, and a plug-in slot is provided on each side surface; or, a plug-in slot is provided on the side wall 1151 of each second shell 12, and a plug-in component is provided on each side surface.

[0061] The first shell 11 and the second shell 12 are matched with each other through the plug-in connector and the plug-in slot, so that the first shell 11 and the second shell 12 are easy to assemble and disassemble, thereby improving practicality.

[0062] It should be noted that the second shell 12 and the first shell 11 may also be directly fixedly connected, that is, the second shell 12 and the first shell 11 are integrally formed.

[0063] In some embodiments, the air inlet 111 extends along the circumference of the surrounding wall 115. The heat exchanger 2 is annular and extends along the circumference of the surrounding wall 115, and the air supply fan 3 is located inside the heat exchanger 2. After the air supply fan 3 draws indoor air into the accommodating chamber 110, the air first exchanges heat with the annular heat exchanger 2 before being discharged through the annular air outlet 112. Before the air flow is blown out of the annular air outlet 112, it fully contacts the annular heat exchanger 2, making the air temperature of the air blown out of the annular heat exchanger 2 more uniform and improving the comfort of the indoor environment.

[0064] In some embodiments, as Figure 1 As shown, the bottom wall of the accommodating cavity is provided with an annular water receiving groove 1101, the top of the annular water receiving groove 1101 is open, and the bottom 113 of the heat exchanger 2 is provided in the annular water receiving groove 1101 so that the annular water receiving groove 1101 can collect condensed water generated on the heat exchanger 2.

[0065] In some embodiments, as Figure 6As shown, the air conditioning device 100 of this embodiment further includes a filter element 4, which is detachably mounted at the air inlet 111 so as to filter the airflow passing through the air inlet 111. The filter element 4 is used to filter the airflow entering the accommodating chamber 110 to remove dust entrained in the airflow, thereby improving the air quality of the air conditioning device 100 of this embodiment.

[0066] In some embodiments, as Figure 6 As shown, the surrounding wall 115 is provided with an installation opening 1153, which is in communication with the air inlet 111. In other words, one end of the installation opening 1153 passes through the outer surface of the surrounding wall 115, and the other end of the installation opening 1153 passes through the inner wall surface of the air inlet 111.

[0067] The filter element 4 includes a mounting portion 41 and a filter portion 42 . The mounting portion 41 is connected to the filter portion 42 . The mounting portion 41 is inserted into the mounting opening 1153 , and the filter portion 42 is located in the air inlet 111 .

[0068] During disassembly, the user can pull the entire filter element 4 out of the mounting opening 1153 through the mounting portion 41. During installation, the user can first insert the filter portion 42 into the air inlet 111 through the mounting opening 1153, and then insert the filter element 4 further into the mounting opening 1153, so that the mounting portion 41 fits into the mounting opening 1153. This facilitates disassembly or installation of the filter element 4 through the mounting opening 1153 without opening the first housing 11, thereby improving practicality.

[0069] Furthermore, if Figure 7 As shown, a clip is provided on the outer surface of the mounting portion 41. The fixed end 4111 of the elastic clip 411 is connected to the mounting portion 41. The free end 4112 of the elastic clip 411 is provided with a protrusion 4113 protruding outward. A relief groove is provided on the outer surface of the mounting portion 41. The relief groove corresponds to the elastic clip 411 so that the relief groove can accommodate the elastic clip 411. The inner wall surface of the mounting opening 1153 is provided with a clip groove 1154 that is compatible with the clip. Thus, the elastic clip 411 cooperates with the clip groove 1154, so that the mounting portion 41 can be more stably fitted into the mounting opening 1153.

[0070] In some embodiments, the inner wall of the receiving groove is provided with a heat insulating layer (not shown in the figure), so that the heat insulating layer can provide heat insulation to the first shell 11 and prevent the generation of condensed water.

[0071] Optionally, the heat insulation layer may be a polyurethane foam material; or, the heat insulation layer may be a glass fiber wool board; or, the heat insulation layer may also be other heat insulation materials.

[0073] The air conditioner of the embodiment of the present invention includes an indoor unit and an outdoor unit, wherein the indoor unit is the air conditioning device 100 of any one of the above embodiments.

[0074] The air conditioner 100 of the air conditioner of the present embodiment not only draws indoor air into the accommodating chamber 110 via the air supply fan 3 and exchanges heat with the heat exchanger 2, but also blows the heated or cooled air into the room, thereby improving the indoor temperature and achieving the purpose of making the user comfortable. Furthermore, the top of the first housing 11 has a first platform 114 for placing items, allowing the air conditioner 100 of this embodiment to also function as other indoor storage structures, such as a desk or coffee table. This improves the home decoration integration of the air conditioner 100 of the present embodiment and enhances the user experience.

[0075] Specifically, the air conditioning device 100 is connected to the air conditioning outdoor unit through a refrigerant pipeline, which includes a gas pipe and a liquid pipe, so that the refrigerant circulates forward or reversely between the air conditioning device 100, the liquid pipe, the air conditioning outdoor unit and the gas pipe in sequence.

[0076] In some embodiments, the refrigerant pipeline is detachably fixedly connected to the connecting pipe portion in the air conditioner indoor unit through a connecting end (not shown in the figure).

[0077] Specifically, the connection end can be a magnetic end, a snap-on end, a sleeve end, a welded pipe joint, etc., which can quickly connect and install the refrigerant pipeline to the pipe joint of the indoor air conditioner unit and the pipe joint of the outdoor air conditioner unit. The connection end can also be provided with a male end and a female end. For example, the pipe joints of the indoor air conditioner unit and the outdoor air conditioner unit are female, and the two ends of the refrigerant pipeline are male. For another example, the end of the refrigerant pipeline facing outdoors is a male end, and the pipe joint of the outdoor unit is a female end, while the end of the refrigerant pipeline facing indoors is a female end, and the pipe joint of the indoor air conditioner unit is a male end.

[0078] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
