[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0037] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0038] In one aspect of the present application, an air outlet frame structure is provided. Figures 1 to 17 The air outlet frame structure includes an air outlet frame body 710, which is provided with an air duct for airflow guidance inside, and an air outlet 701 is provided on the air outlet frame body 710; an air outlet panel 720, which is provided on the air outlet frame body 710, and the air outlet panel 720 is adapted to the air outlet 701; wherein the air outlet panel 720 and the air outlet frame body 710 are integrally formed.

[0039] The air outlet frame structure of the present application significantly improves the production efficiency and appearance quality of the air conditioner indoor unit by adopting the design scheme of the air outlet panel 720 and the air outlet frame body 710 being integrally formed, and also optimizes the air flow guiding performance. Specifically, firstly, the integrally formed air outlet frame structure avoids the assembly requirements of multiple independent parts in the traditional separate structure, thereby reducing the internal complexity of the air conditioner and reducing the total number of parts. This not only simplifies the assembly process, reduces labor costs and the possibility of assembly errors, but also shortens the production cycle and improves production efficiency. Secondly, since the air outlet panel 720 and the air outlet frame body 710 are integrally formed, there is no need to perform additional sealing treatment between the two, which effectively avoids the problem of condensed water leakage caused by the poor sealing of the parts connection in the traditional separate structure. The integrally formed structure naturally forms a more tightly enclosed space, ensuring that the condensed water can be completely drained to the water receiving tray component 300, avoiding the condensed water from dripping onto the customer's floor and flowing to the electrical box component 500, and improving the electrical safety performance. Thirdly, due to the connection and matching between parts, the traditional separated structure often leaves gaps or uneven marks on the appearance, affecting the overall appearance. The one-piece molding design of the present application eliminates these appearance defects, so that the secondary appearance surface 724 and the main appearance surface 725 of the air outlet frame structure present a smoother and more delicate surface, which improves the neatness and high-end texture of the appearance of the air conditioner. In addition, the one-piece molded air outlet frame structure effectively improves the structural strength between the air outlet frame body 710 and the air outlet panel 720. The problem of structural looseness or vibration caused by the independence of parts is reduced, making the overall structure of the air outlet frame more stable and durable, and reducing the failure rate of the air conditioner during long-term use.

[0040] In summary, the one-piece air outlet frame structure of the present application shows significant beneficial effects in reducing the number of parts, improving assembly efficiency, optimizing sealing, improving appearance quality, enhancing structural strength and optimizing airflow control, and effectively solves the technical problems caused by the separate structure. This design not only improves the overall performance and user experience of the air conditioner, but also reduces production costs and the difficulty of later maintenance, and has high market application value and promotion potential. It can be seen that this design not only simplifies the manufacturing and assembly process of the air outlet frame structure, but also improves its overall strength and stability. It is suitable for various household and commercial air conditioner indoor units, especially in occasions that require frequent disassembly and maintenance. The one-piece air outlet frame structure can significantly reduce assembly time and reduce maintenance costs, thereby providing users with a more convenient service experience.

[0041] In this embodiment, if Figures 1 to 8As shown, the air outlet panel 720 and the air outlet frame body 710 are integrally injection molded; and / or there are two air outlets 701 and air outlet panels 720, and the two air outlets 701 are arranged in a one-to-one correspondence with the two air outlet panels 720. The one-piece injection molding process can ensure the seamless connection between the air outlet panel 720 and the air outlet frame body 710, avoid airflow leakage, and improve the energy efficiency of the air conditioner. The design of the two air outlets 701 and the air outlet panel 720 can achieve a more uniform airflow distribution, which is suitable for rooms that need to cover a large area, such as living rooms, offices, etc., providing a more comfortable air conditioning experience, especially in a multi-person family or office environment, can meet the temperature requirements of different areas and improve the overall comfort.

This structural design allows the air guide plate to flexibly adjust the air outlet direction to meet the needs of different users for the air supply angle of the air conditioner. Especially in the home, the air supply direction can be adjusted according to the activity area of ​​​​family members to improve comfort. It is also suitable for hotel rooms, conference rooms and other scenes.

This design enables the air outlet frame structure to work in coordination with other moving parts of the air conditioner, ensuring that the large door panel can be automatically opened when the air conditioner is started. This not only improves the degree of automation of the air conditioner, but also enhances the user experience, especially in smart air conditioners, which can achieve more intelligent control, such as remote control of opening and closing the door through a mobile phone, bringing users a more convenient lifestyle.

[0044] In this embodiment, a limit pin 711 is provided on the air outlet frame body 710, which is used to cooperate with the support plate (left support plate 203, right support plate 204) of the evaporator component 200 of the air conditioner; a limit opening 210 is provided on the support plate (left support plate 203, right support plate 204) of the evaporator component 200, which cooperates with the limit pin 711. The matching design of the limit pin 711 and the limit opening can ensure the stability and positioning accuracy of the evaporator component during the operation of the air conditioner, avoid the displacement of the components caused by vibration, improve the operation efficiency and reliability of the air conditioner, and is suitable for all types of air conditioners, especially those large air conditioners that generate large vibrations during operation, such as industrial air conditioners and commercial building air conditioning systems, which can effectively reduce equipment failures and extend service life.

[0059] The present invention includes an air inlet component, an evaporator component 200, a lower water tray component 300, a fresh air component 400, an electrical box component 500, an air duct component 600, an air outlet frame component, a chassis component 800, a lower panel component 900, a main panel component 1000, a left door panel component 1100, a right door panel component 1200, and a top cover component 1300.

[0060] The air outlet frame components include a left air guide plate 730, a right air guide plate 740, a left foam 703, a right foam 705, a left mesh cover 704, and a right mesh cover 706. The air guide plate assembly (left air guide plate 730, right air guide plate 740) realizes left and right air guides, and left and right foams (left foam 703, right foam 705) are designed on the left and right sides of the air outlet frame body 710 for heat preservation, and mesh covers (left mesh cover 704, right mesh cover 706) are designed at the left and right air outlets.

[0061] The left and right sides of the air outlet frame body 710 are assembled to the left support plate 203 and the support plate 204 of the evaporator. The left and right support plates are arranged on the air inlet panel of the air inlet component. The left and right support plates are sheet metal parts. The upper and lower ends of the air outlet frame structure 700 are connected and fixed to the air inlet panel. The invention indirectly connects the air outlet frame and the air inlet panel through the left and right support plates of the evaporator component, which can reduce the direct contact between the air outlet frame and the air inlet panel and avoid abnormal noise caused by thermal expansion and contraction of the injection molded parts.

[0062] The air outlet frame structure 700 is connected with the air duct component 600 by snapping on one side corresponding to the double air outlets, and fixed by screws on the other side. Fillers such as sponges are arranged at the contact position between the air outlet frame and the air duct snapping to prevent abnormal noises caused by thermal expansion and contraction of the injection molded parts.

[0063] A main panel component 1000 is assembled in the middle of the air outlet frame structure 700 and is fixed by buckles and screws.

[0064] Compared with competing products, the left moving component 750 and the right moving component 760 of this application are assembled on the air outlet frame from left to right, and the four moving components are respectively arranged at the upper left, lower left, lower right and upper right positions of the air outlet frame. The left large door panel component 1100 and the right large door panel component 1200 are assembled on the moving components. When the machine is turned on, the large door panels are opened. Compared with competing product solutions, the solution in this application can avoid opening a mechanism movement clearance port on the secondary appearance surface, thereby improving the neatness of the whole machine.

[0065] The air outlet frame body 710 cooperates with the water receiving tray component 300 through latches and screws, and is fixedly connected with the lower panel component 900 through latches and screws, thereby enhancing the front end strength of the whole machine and preventing the whole machine from being unstable.

[0066] The present invention adopts an integrated design of the air outlet frame, that is, the air outlet panel is integrated with the air outlet frame, which increases the structural strength of the parts and reduces the gaps between the multiple independent parts during assembly, which will significantly improve the sealing, anti-condensation and noise. The air outlet frame structure is mounted on one side of the mesh cover by a buckle, and the other side is fixed by a screw. The interference between the buckle opening and the mesh cover is in the range of 0.1mm≤interference≤1mm, which prevents the mesh cover from falling out under external force and ensures the spacing between the mesh cover and the left and right ends of the air outlet. The invention can solve the problem of fingers entering the air duct and touching the fan blades, causing finger injuries.

[0067] A water receiving structure is designed at the lower end of the front of the air outlet frame, which can drain the condensed water on the front to the lower water receiving tray 301, and the condensed water on the air guide plates at the two air outlets can be drained from the front to the water receiving tray component 300 (including the upper water receiving tray 302 and the lower water receiving tray 301). The water in the pipes on both sides of the air duct component 600 and the evaporator component 200 can also be drained to the lower water receiving tray 301 through the air outlet frame water receiving structure, and finally led to the outside through the drain pipe 303. The invention has the air outlet frame water receiving structure extend beyond the outer edges of both sides of the water receiving tray, so that the condensed water of the entire machine can be drained to the water receiving tray through the air outlet frame or directly flow to the water receiving tray, thereby solving the problem of condensed water dripping onto the customer's floor and flowing to the electrical box component 500 after the air conditioner produces condensed water, causing electrical safety.

[0068] The air guide assembly includes two left and right air guide plates, two left and right support frames, an air guide connecting rod, and upper and lower shaft sleeves. The air outlet needs to be designed as an arc-shaped expansion structure. During the air guiding process, the movement gap between the air guide plate and the air outlet frame can be 1mm≤L1≤6mm. When guiding the air forward, the smaller L1, the better, so that the airflow at the air outlet can be sent forward, reducing the airflow out from both sides. The airflow is sent forward, which can increase the air volume sent forward, thereby increasing the air supply distance. If L1 is too small, it will cause the air guide plate to collide with the arc structure of the air outlet frame, resulting in problems with smooth operation. The L1 value recommended in the present invention is 3mm±1mm, which can make the air supply distance reach more than 5m in the cooling state.

[0069] The present invention increases the air supply angle by designing the angle of the two air outlets to be greater than or equal to 90 degrees. When the air is supplied at the maximum angle, the maximum left and right wind sweeping angle range of the outer side is 150°, and the windless zone range of the inner side can reach 120°.

[0070] In summary, the inventions in this application include:

[0071] 1. Since the present invention adopts a design in which the air outlet frame and the left and right air outlet panels are integrally formed, the number of parts of the left and right air outlet panels is reduced, thereby improving production efficiency.

[0072] 2. The present invention adopts a method of assembling the air outlet frame component on the left and right support plates of the evaporator component, which solves the problem of abnormal noise caused by thermal expansion and contraction in the heating state without adding sponge and flannel, thereby improving production efficiency.

[0073] 3. The moving parts of the door panel of the present invention are assembled on the air outlet frame from left to right, which can avoid the need to open a mechanism movement clearance opening on the secondary appearance surface, thereby improving the neatness of the whole machine.

[0074] 4. The present invention provides a water receiving and diversion structure on the air outlet frame to divert all condensed water to the water receiving tray, thereby preventing the condensed water generated by the air conditioner from dripping onto the customer's floor and flowing onto the electrical box components, causing electrical safety problems.

[0075] 5. The present invention designs an arc expansion structure for the air outlet, and the movement gap between the air guide plate and the arc expansion structure of the air outlet is 1mm≤L1≤6mm, which can lengthen the air supply distance and increase the air supply angle.

[0076] Correspondingly, the technical effects brought about by the technical solution in this application include:
