[0034] Traditional air conditioning equipment usually installs wire meshes at the air outlets to prevent users from touching the moving parts inside the air conditioner. Among them, since the installation process of the wire meshes requires additional manual operations, this undoubtedly increases the assembly cost and reduces the assembly efficiency.
[0035] To solve this technical problem, the present utility model proposes an indoor unit of an air conditioner.
[0036] Please refer to Figures 1 to 5 , in an embodiment of the present utility model, the indoor unit of the air conditioner includes an air duct housing 10 and an air outlet structure 20. The air duct housing 10 has an air duct outlet 11; the air outlet structure 20 includes an air outlet frame 21 and a grille 26. The air outlet frame 21 is provided at the air duct outlet 11, and the grille 26 is provided inside the air outlet frame 21 and is integrally formed with the air outlet frame 21. With such a setting, the assembly efficiency of the indoor unit of the air conditioner is improved, and at the same time, the assembly cost is effectively saved.
[0037] In the technical solution of the present utility model, through the integral molding of the grille 26 and the air outlet frame 21, compared with using additional assembly steps to install the grille 26, it helps to reduce the assembly steps of installing the grille 26. Furthermore, it helps to reduce the assembly cost. At the same time, it can also improve the assembly efficiency of the indoor unit of the air conditioner and improve the use reliability of the air outlet structure 20.
[0038] It should be noted that the gap and strength design of the grille 26 of the present utility model need to meet the safety regulations requirements to ensure that users cannot touch the impeller and realize the safe use of the indoor unit of the air conditioner. The integral molding of the grille 26 and the air outlet frame 21 can effectively enhance the structural strength of the air outlet frame 21. At the same time, it eliminates the safety hazard of the grille 26 falling off, and ensures the assembly efficiency of the air outlet structure 20 and the air duct housing 10.
[0039] Optionally, in an embodiment of the present utility model, the grille 26 and the air outlet frame 21 are integrally injection molded, which helps to reduce subsequent assembly steps and costs. And due to the characteristics of the integral injection molding process, it is convenient for mass production and automated production, improves the production efficiency of the air outlet structure 20, can also ensure the quality of the air outlet structure 20, and at the same time, improves the utilization rate of the molding material and reduces the material cost.
[0040] Among them, in an embodiment, the grille 26 is configured as a non-plastic part, the air outlet frame 21 is configured as a plastic part, and the grille 26 and the air outlet frame 21 are integrally formed by insert injection molding; in this way, an air outlet structure 20 with a complex structure can be manufactured. At the same time, the structural strength of the air outlet structure 20 is improved, and it is also convenient to realize automated production and improve the production efficiency of the air outlet structure 20.
[0041] In another embodiment, both the grille 26 and the air outlet frame 21 are configured as plastic parts, and the grille 26 and the air outlet frame 21 are integrally formed by one-shot injection molding; in this way, a complex air outlet structure 20 can be manufactured. At the same time, the utilization rate of the molding material is improved, the material cost is reduced, and it is also convenient to realize automated production and mass production, improving the production efficiency and production cost of the air outlet structure 20.
[0042] Optionally, in the embodiment of the present invention, the grille 26 and the air outlet frame 21 are integrally die-cast, which helps to reduce subsequent assembly steps and costs. Moreover, due to the characteristics of the integral die-casting process, it is convenient for mass production and automated production, improving the production efficiency of the air outlet structure 20. It can also ensure the quality of the air outlet structure 20. At the same time, the utilization rate of the molding material is improved, and the material cost is reduced.
[0043] Please refer to Figure 3 , in the embodiment of the present invention, an air outlet section 24 and a wind guiding section 23 are provided in the air outlet frame 21. The wind guiding section 23 is used to connect the air duct outlet 11 and the air outlet section 24. The wind guiding section 23 is arranged in a gradually expanding manner in the direction from the air duct outlet 11 to the air outlet section 24. Among them, the outlet of the air outlet section 24 away from the wind guiding section 23 is configured as the air outlet 22 of the air outlet frame 21, and the diameter of the air outlet 22 is larger than the diameter of the air duct outlet 11. Therefore, through the gradually expanding setting of the wind guiding section 23, it adaptively cooperates with the change in the diameter from the air duct outlet 11 to the air outlet 22 to form a buffer diffusion area for the air flow, which helps to reduce the wind pressure and the air outlet resistance. Furthermore, the air flowing out from the air outlet 22 can be made more uniform and gentle, reducing the air duct noise of the indoor unit of the air conditioner and improving the user's comfort at the same time.
[0044] Furthermore, a wind guiding component for adapting to different temperature adjustment modes of the air conditioner can be rotatably installed in the air outlet section 24. By using the rotation of the wind guiding component in the air outlet section 24 and the guiding part extending out of the air outlet 22, in the cooling mode of the air conditioner, the air flow at the air outlet 22 is blown upward, and in the heating mode of the air conditioner, the air flow at the air outlet 22 is blown to one side of the air conditioner. Furthermore, the temperature adjustment effect of the air conditioner is improved, so as to accelerate the rapid mixing of the indoor temperature in different modes, which helps to save electric energy.
[0045] Specifically, in the embodiment of the present utility model, the grille 26 is disposed between the air guiding section 23 and the air outlet section 24. With such a setting, the air flow flowing out from the air duct outlet 11 can form a uniform and gentle air flow under the buffering effect of the air guiding section 23 and then be blown out by the grille 26, improving the design of no wind feeling and low noise of the indoor unit of the air conditioner. By arranging the air outlet section 24 on the side of the grille 26 facing away from the air guiding section 23, the change of the air flow direction can be realized, that is, the specific shape of the air outlet section 24 and / or the air guiding component in the air outlet section 24 can be used to achieve the purpose of changing the air flow direction. Therefore, setting the grille 26 between the air guiding section 23 and the air outlet section 24 can not only ensure the buffering and noise reduction of the air flow, but also reserve space for the assembly of the air guiding component and the change of the air flow direction, improving the miniaturization level and temperature regulation effect of the indoor unit of the air conditioner. However, this design is not limited thereto. In other embodiments, the grille 26 is disposed in any one of the air guiding section 23 and the air outlet section 24.
[0046] Limited by the installation of the grille 26 in the air outlet frame 21 and the integral molding of the grille 26 and the air outlet frame 21, for the convenience of demolding the air outlet structure 20, please refer to Figures 3 to 5 , in the embodiment of the present utility model, an installation opening 231 is formed on the channel wall of the air guiding section 23, and a guiding structure 25 is installed in the installation opening 231. The guiding structure 25 has a guiding surface 252 that gradually approaches the air outlet section 24. Among them, the installation opening 231 is communicated with the through hole of the air guiding section 23 that is communicated with the air duct outlet 11, which is convenient for the air guiding section 23 to be demolded from the injection mold. The guiding structure 25 is installed in the installation opening 231, which can not only seal the installation opening 231 and reduce air leakage, but also buffer the air flow flowing out from the air duct outlet 11 by using the setting that the guiding surface 252 gradually approaches the air outlet section 24 to obtain a gentle and mild air flow.
[0047] Among them, the guiding structure 25 and the air guiding section 23 are fixed into a whole by non-detachable means such as welding and bonding, which helps to realize the integration of the air outlet structure 20, ensure the structural strength and airtightness of the air outlet structure 20, and at the same time, reduce the assembly steps and improve the assembly efficiency of the indoor unit of the air conditioner; or, the guiding structure 25 and the air guiding section 23 are fixed into a whole by detachable means such as clamping and plugging, which is convenient for flexible replacement and selection of guiding structures 25 with different guiding effects, realizing the diversification of the air outlet structure 20.
[0048] Specifically, in the embodiment of the present utility model, the longitudinal section contour line of the guiding surface 252 is a straight line or an arc, and the longitudinal section is specifically Figure 3The cross-section in the vertical direction shown. At this time, the contour line of the diversion surface 252 extends toward the air outlet section 24 at the end far from the air duct housing 10 to adapt to the change in the caliber of the air guiding section 23. On this basis, the longitudinal cross-section contour line of the diversion surface 252 can be a straight line or an arc. When the contour line is a straight line, the diversion surface 252 is inclined upward as a whole; when the contour line is an arc, at least part of the diversion surface 252 protrudes downward. However, the present design is not limited to this. In other embodiments, the longitudinal cross-section contour line of the diversion surface 252 is a polyline, and the polyline includes but is not limited to straight line segments and arc segments.
[0049] Please refer to Figure 3 , in an embodiment of the present utility model, the diversion structure 25 includes a diversion plate 251 and two connecting plates 253 provided on opposite sides of the diversion plate 251. The connecting plates 253 are connected to the installation opening 231. The inner surface of the diversion plate 251 is the diversion surface 252. It can be understood that the diversion structure 25 is connected to the installation opening 231 through the connecting plates 253, and the air flow flowing out of the air duct outlet 11 is diverted and buffered by the diversion surface 252 on the diversion plate 251. Among them, the end of the connecting plate 253 far from the diversion plate 251 is adapted to the edge of the installation opening 231, which is convenient for sealing design and the assembly of the diversion structure 25. And because the height of the diversion plate 251 in the vertical direction will also affect the diversion effect of the diversion plate 251 and the buffering effect of the air guiding section 23, the installation opening 231 of the air guiding section 23 is opened far from the air duct outlet 11 and has a certain distance from the plane where the air duct outlet 11 is located, which is convenient for the forming and demolding of the air guiding section 23 and also facilitates the selection of the height of the connecting plate 253, so as to facilitate the design of the longitudinal cross-section contour line of the diversion surface 252 and improve the diversion effect and buffering effect of the air guiding section 23. However, the present design is not limited to this. In other embodiments, the diversion structure 25 only includes the diversion plate 251.
[0050] Specifically, please refer to Figure 5 , in an embodiment of the present utility model, one end of the connecting plate 253 is connected to the diversion plate 251, and the other end is snap-connected to the edge of the installation opening 231. It can be understood that the connecting plate 253 and the channel wall of the air guiding section 23 are connected through the snap structure 255, and its disassembly and assembly are fast and convenient; among them, the snap structure 255 includes a snap and a snap opening. One of the snap and the snap opening is provided on the connecting plate 253, and the other is provided on the channel wall of the air guiding section 23. For example, a convex is provided on the outer side of the channel wall, and a snap opening is formed on the convex. At this time, the connecting plate 253 is provided with a snap that can be inserted into the snap opening.
[0051] Please refer to Figure 4, in an embodiment of the present utility model, the connecting plate 253 is provided with a sealing groove 254 for inserting the hole wall of the mounting opening 231. At this time, the end of the connecting plate 253 close to the mounting opening 231 forms a U-shaped sealing groove 254. When the hole wall of the mounting opening 231 is inserted into the sealing groove 254, a tortuous channel is formed between the groove wall of the sealing groove 254 and the hole wall. The air flow in the air guiding section 23 will produce a throttling effect when passing through the tortuous channel, so as to achieve the purpose of leakage prevention. Furthermore, the risk of air leakage can be reliably reduced, and the energy efficiency of the indoor unit of the air conditioner can be improved. Of course, in other embodiments, a sealing medium is also provided in the sealing groove 254, which helps to improve the overall sealing performance of the indoor unit of the air conditioner and can also improve the connection strength between the flow guiding structure 25 and the air guiding section 23.
[0052] When the connecting plate 253 and the channel wall of the air guiding section 23 are connected through the buckle structure 255, the buckle structure 255 can be formed on the groove side wall of the sealing groove 254.
[0053] The present utility model also proposes an air conditioner, which includes an indoor unit of the air conditioner. The specific structure of the indoor unit of the air conditioner refers to the above embodiments. Since this air conditioner adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.
[0054] Optionally, in an embodiment of the present utility model, the air conditioner further includes an outdoor unit of the air conditioner, and the outdoor unit of the air conditioner is connected to the indoor unit of the air conditioner through a flexible refrigerant pipe; specifically, the air conditioner of the present utility model can be a split air conditioner that is convenient for users to install personally. It uses a flexible refrigerant pipe to connect the indoor heat exchanger of the indoor unit of the air conditioner and the outdoor heat exchanger of the outdoor unit of the air conditioner, and injects refrigerant into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the indoor unit and the outdoor unit of the air conditioner respectively, and does not need to assemble the refrigerant pipe and add refrigerant, thereby reducing the installation difficulty and realizing personal installation by the user. However, this design is not limited to this. In other embodiments, the air conditioner of the present utility model can also be a common split air conditioner.
[0055] Optionally, in an embodiment of the present utility model, the compressor of the air conditioner is arranged in the indoor unit of the air conditioner, which can reduce the weight of the outdoor unit of the air conditioner, thereby facilitating the installation of the outdoor unit of the air conditioner; correspondingly, the compressor is also provided with a noise reduction structure to ensure low-noise operation of the indoor unit of the air conditioner.
