[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] In devices with infrared receiving functions, the shell is usually made of plastic. However, in order to improve the appearance quality, the infrared function is hidden in the appearance, which has the problem of weakened signal reception range. Taking air conditioners as an example, when users use the remote control to control the air conditioner, they may need to be very close to the air conditioner body to operate it effectively. In other words, they may operate according to the recommended distance in the manual, but signal delays or unresponsiveness are often encountered.

[0029] Currently, split portable air conditioners are typically made of plastic with a heavily frosted surface finish to maintain aesthetic appeal. This can lead to one or more of the following issues: First, the remote control range is limited. Users may need to be very close to the unit to effectively operate it. In other words, even if the user operates the unit within the recommended distance specified in the user manual, signal delays or even no response are common. Second, signal instability can occur. When attempting to control the unit from different locations around the room, the signal may become unstable at certain angles or distances, sometimes working and sometimes unresponsive, causing inconvenience.

[0030] First, users need to frequently adjust their position or the remote control to ensure smooth signal transmission, which not only reduces the convenience of use but also affects the overall user experience. Furthermore, when the air conditioner settings need to be adjusted quickly (such as suddenly feeling too cold or too hot), due to the limitations of remote control distance and signal stability, users may not be able to quickly achieve the desired adjustment effect, resulting in untimely indoor temperature adjustment. In fact, if users face such usage problems for a long time, they may doubt the quality and performance of the product, which in turn affects their favorability and loyalty to the brand. Moreover, some users may contact after-sales service because they cannot solve the remote control problem by themselves. The increase in after-sales service demand increases the manufacturer's service cost and the user's time cost (especially in areas with less after-sales service). Therefore, improving the sensitivity and distance of the air conditioner remote control reception and optimizing the appearance material selection and surface treatment process are important aspects of improving the overall product usage experience and user satisfaction.

[0031] To this end, the present invention provides a housing. In this embodiment, the housing is a housing of an indoor unit of an air conditioner (i.e., a protective and visible housing of the indoor unit of the air conditioner). In other embodiments, the housing can also be used in household appliances with infrared functions, such as fans, dehumidifiers, etc.

[0032] See also Figures 1 to 5 In one embodiment of the present invention, the housing 100 includes a housing body 110 and a remote control mounting position 120. The housing body 110 includes an outer surface 102 and an inner surface 101 opposite to the outer surface 102. Figure 2 , the remote control installation position 120 is provided on the inner surface 101 of the shell body 110, referring to Figure 1 and Figure 4 The remote control installation position 120 is used to install the infrared remote control box 200. The remote control installation position 120 is also provided with a thinning area 121. The signal end 210 of the infrared remote control box 200 faces the thinning area 121, and the thickness of the thinning area 121 is less than the thickness of the surrounding area.

[0033] In the technical solution of the present invention, the remote control mounting position 120 is provided on the inner surface 101 of the shell body 110, and the outer shell 100 hides the infrared remote control box 200, thereby improving the appearance quality of the air-conditioning product and making the appearance surface of the air-conditioning product more integrated. In order to improve the problem of weakened signal reception range when the outer surface 102 of the shell body 110 is subjected to frosted etching treatment, the inner surface 101 is further provided with a thinned area 121. The shell body 110 has the smallest thickness in the thinned area 121, and the signal end 210 of the infrared remote control box 200 faces the thinned area 121, which helps to reduce energy loss or interference during the reception process. The signal can be better received from the thinned area 121, avoiding the problem that when the user uses the remote control to control the air conditioner, it may be very close to the air conditioner body to effectively operate. In other words, even if the operation is performed at the recommended distance in the manual, signal delay or unresponsiveness may often occur. Or when the user tries to control the remote control at different locations in the room, the remote control signal may become unstable at certain angles or distances, sometimes being able to control and sometimes not responding, causing inconvenience in use.

[0034] In this embodiment, the signal end 210 is the receiving end of the infrared remote control box 200; in other embodiments, the housing 100 can be used as a shell of an infrared transmitting device, such as a remote control shell; the signal end 210 serves as a transmitting end, and the intensity of the transmitted signal is improved by setting the thinning area 121.

[0035] Reference Figure 1 and Figure 4 The outer surface 102 and the inner surface 101 of the shell body 110, that is, the outer surface and the inner surface of the air conditioner indoor unit, the remote control installation position 120 is the area for installing and arranging the infrared device, which is an area defined by several ribs. The ribs can be provided with mounting holes for locking and fixing the infrared remote control box.

[0036] In this embodiment, injection molding is used to form shells of different thicknesses, and the thinning portion of the shell is set as a thinning area 121. It can be understood that since the wall thickness is reduced, the signal reception is improved to a certain extent.

[0037] Reference Figure 5, in order to maximize the infrared reception effect while taking into account production and manufacturing, the thickness of the shell body 110 in the thinning area 121 is d, where 1.2 mm ≤ d ≤ 1.6 mm. On the one hand, the smaller the thickness of the thinning area 121, the better the reception effect of the thinner thinning area 121. On the other hand, the more difficult the injection molding process, the more obvious the problems of surface deformation and air streaks, which not only affect the appearance of the product but also cannot meet the usage requirements. After using the product for a period of time, wrinkles may occur, and users may doubt the quality and performance of the product, thereby affecting the favorability and loyalty to the brand. Limiting the thickness d of the thinning area within the above range can take into account production and manufacturing while improving the infrared reception effect.

[0038] Specifically, the maximum thickness of the shell body 110 is D, where 1.6 mm < D < 4 mm. When the maximum thickness of the shell body 110 is D and the thickness ratio range of 0.45 < d / D < 0.7 is satisfied, the structural strength, surface quality, and overall performance of the product can be ensured to reach the optimal state. The thickness of the shell body 110 is 2 mm, 2.5 mm, 2.8 mm, 3 mm, 3.2 mm, 3.5 mm, etc.

[0039] On the basis of controlling the thickness of the thinning area 121, in order to further reduce the problems of deformation and / or air streaks on the surface of the shell caused by the increasing difficulty of the injection molding process, the shell body 110 also has a transition area 122 at the remote control installation position 120, and the thickness of the shell body 110 gradually decreases from the transition area 122 to the thinning area 121. As an area where the thickness of the shell body 110 gradually changes, the transition area 122 can relieve the stress concentration problem caused by the direct transition from the thicker part to the thinning area 121. By gradually reducing the thickness, the injection molding material can fill the mold more evenly during the flow process, reducing air streaks and deformation caused by uneven flow.

[0040] Refer to Figure 2 and Figure 3 , specifically, the transition area 122 is arranged around the thinning area 121. The transition area 122 should be arranged around the thinning area 121 to form a continuous transition zone. This can ensure that the thinning area 121 has sufficient support and buffering in all directions, preventing deformation and cracks caused by excessive thickness change. During the injection molding process, due to material cooling shrinkage and the limitation of the mold structure, stress concentration is likely to occur in the area of the shell body 110 with a large thickness change. By arranging the transition area 122 around the thinning area 121, the material flow and cooling can be gradually guided, thereby relieving stress concentration and reducing the generation of deformation and cracks.

[0041] Specifically, in order to reduce the impact of air streaks, the extension length of the transition zone 122 ≥ 10 mm. A gradual transition zone 122 of more than 10 mm is adopted to ensure an area with a gradually changing thickness and sufficient length, providing a longer flow path for the injection molding material. This helps the material to exhaust gas better during the flow process, reducing the possibility of gas being trapped in the plastic; thus, it can alleviate the stress concentration problem caused by the direct transition from the thicker part to the thinning zone 121, reducing the impact of air streaks on the surface; moreover, the extension of the transition zone 122 also means that the material has more time to gradually adapt to the temperature change during the cooling process. This helps to reduce the internal stress generated due to the sharp temperature drop, further reducing the generation of air streaks. The transition zone 122 is arranged around the thinning zone 121, that is, the area enclosed by the transition zone 122 is not larger than or slightly larger than the remote control signal transmission box. The extension length can be 10 mm, 13 mm, 15 mm, 25 mm, 30 mm, etc.

[0042] To balance the structural requirements of the product and the feasibility of the injection molding process, the maximum thickness of the shell body 110 is D, and 0.45 < d / D < 0.7. Here, d / D represents the ratio between the thickness d of a local area of the thinning zone 121 and the maximum thickness D of the shell body 110. By limiting the parameter within a relatively reasonable thickness change range, it aims to balance the structural requirements of the product and the feasibility of the injection molding process. During the injection molding process, thicker areas require more material to fill, while thinner areas are relatively easier to fill. By controlling the ratio of d / D within a reasonable range, it can ensure that the material flows more evenly within the shell body 110, reducing air streaks and shrinkage holes caused by poor flow. According to the ratio range of 0.45 < d / D < 0.7, the thickness of the transition zone 122 can gradually decrease from a value close to D to a value close to a certain value between 0.45*D and 0.7*D.

[0043] In order to make the surface of the molded part smooth to enhance the signal reception effect, the inner surface 101 of the shell body 110 is subjected to mirror polishing treatment. When the outer surface 102 does not require a matte design, the outer surface 102 of the shell body 110 is subjected to mirror polishing treatment.

[0044] For convenient installation, the remote control installation position 120 and the infrared remote control box 200 are fixedly connected by a clamping structure 300. Specifically, in this embodiment, clamping buckles 310 are provided on opposite sides of the remote control installation position 120, and the infrared remote control box 200 correspondingly has clamping grooves or protrusions. During installation, the infrared remote control box 200 is pressed so that the clamping buckles 310 are clamped to the infrared remote control box 200 for fixation; in other embodiments, the clamping structure 300 can also be in other forms, such as having clamping buckles 310 at the four corners; or the infrared remote control box 200 can be fixed with screws.

[0045] The present invention also provides an air conditioner, comprising an indoor unit, an outdoor unit, a housing 100, and an infrared remote control box 200. The specific structure of the housing 100 is similar to that of the above-mentioned embodiments. Since the present air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here. The housing 100 is the housing 100 of the indoor unit (i.e., the protective and visible housing of the indoor unit). The air conditioner includes the indoor unit and the outdoor unit. A refrigerant pipe group (usually a copper pipe) extends through the housing of the air conditioner to connect the indoor unit and the outdoor unit. The indoor unit and the outdoor unit can be integrated into one unit. In this case, the air conditioner is a mobile air conditioner, requiring no external exhaust pipe or outdoor unit. All components are integrated into a single unit. However, the indoor unit and the outdoor unit are connected by a flexible refrigerant pipe. The compressor of the air conditioner can also be installed in the indoor unit.

[0046] This makes the split-type air conditioner easy for users to install. It uses flexible refrigerant piping to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit. Refrigerant is already injected into the refrigerant circuit before the unit leaves the factory. This allows users to install the unit themselves by simply securing the indoor and outdoor units separately, eliminating the need to assemble refrigerant piping or inject refrigerant. This simplifies installation and makes it easy for users to install the unit themselves.

[0047] Placing the compressor in the indoor air conditioner reduces the weight of the outdoor unit, making it easier for users to move the outdoor unit to a suitable installation location. This reduces installation effort and labor costs, especially in areas with high labor costs. To reduce noise, the indoor unit's compressor is also treated with noise-reducing materials, such as filling it with noise-reducing materials or installing a buffer structure to reduce the transmission of compressor vibration.

[0048] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
