Description

Technical Field

[0001] The present invention relates to the field of air conditioning, and in particular to an air conditioning indoor unit. Background Art

[0002] In modern homes, embedded air conditioner indoor units are widely used in customized home settings such as kitchens and wardrobes due to their space-saving and aesthetically pleasing features. This installation method cleverly integrates the air conditioner into the home environment, meeting users' needs for indoor temperature regulation while enhancing the overall aesthetics of the space, making it a popular choice for those pursuing a high-quality home lifestyle.

[0003] However, existing built-in air conditioner indoor units generally adopt a top air intake and front air outlet structure, which requires sufficient space to be reserved above the cabinet to ensure air circulation at the air inlet. This not only greatly increases the difficulty of cabinet design and installation, but also seriously limits the effective use of space in kitchen wall cabinets, wardrobe top cabinets, etc.

[0004] To improve space usage, some products have attempted to adopt a front-up intake and front-down exhaust layout, but this presents new challenges. During operation, due to the close proximity of the air inlet and outlet, some of the airflow from the outlet is drawn directly into the inlet before fully participating in indoor air circulation, creating an airflow short-circuit. This not only significantly reduces the cooling and heating efficiency of the air conditioner and significantly increases energy consumption, but also generates abnormal noise due to localized airflow disturbances, significantly impacting the user experience and the lifespan of the device. Summary of the Invention

[0005] An object of the present invention is to overcome at least one technical defect in the prior art and provide an air conditioner indoor unit.

[0006] A further object of the present invention is to use the air outlet panel as a physical barrier to block the upward flow path of the air outlet, avoid air flow short circuit phenomenon, and improve the cooling / control efficiency of the air conditioner.

[0007] Another further object of the present invention is to improve the smoothness and stability of the air outlet panel switch.

[0008] Yet another further object of the present invention is to reduce the difficulty of rotating the air outlet panel.

[0009] In particular, the present invention provides an air conditioner indoor unit, comprising:

[0010] The housing has an air outlet at a lower area of the front side thereof;

[0011] an air outlet panel, disposed at the air outlet; and

[0012] At least one transmission mechanism is disposed in the housing and connected to the air outlet panel, and is configured to drive the air outlet panel in a controlled manner so that the lower edge of the air outlet panel turns upward and outward, thereby opening the air outlet.

[0013] Optionally, the transmission mechanism includes:

[0014] A first transmission member, a front end of which forms a first hinge point with the air outlet panel; and

[0015] a second transmission member, a front end of which forms a second hinge point with the air outlet panel, wherein the second hinge point is located higher than the first hinge point;

[0016] The first transmission member is used to move forward in a controlled manner to push the air outlet panel outward, and the second transmission member is used to constrain the movement trajectory of the second hinge point during the pushing process of the air outlet panel, so that the air outlet panel produces a rotational displacement around the second hinge point to flip the lower edge of the air outlet panel upward.

[0017] Optionally, the first transmission member extends obliquely upward from rear to front, so as to push the air outlet panel toward the front and upward when moving forward in a controlled manner;

[0018] The first transmission member is provided with a guide groove extending downward from back to front, and a guide rod is provided at the rear end of the second transmission member. During the pushing out process of the air outlet panel, the guide rod slides and rotates in the guide groove, thereby constraining the movement trajectory of the second hinge point.

[0019] Optionally, a first hinge shaft and a second hinge shaft are provided on the inner side of the air outlet panel, the second hinge shaft is located higher than the first hinge shaft, and the axes of the second hinge shaft and the second hinge shaft are arranged in the transverse direction of the air outlet panel;

[0020] A first hinge hole is provided at the front end of the first transmission member, and the first hinge shaft is inserted into the first hinge hole to form the first hinge point that can rotate relatively;

[0021] A second hinge hole is provided at the front end of the second transmission member, and the second hinge shaft is inserted into the second hinge hole to form the second hinge point which can rotate relatively.

[0022] Optionally, a connecting piece is provided on the inner side of the air outlet panel, and the first hinge shaft and the second hinge shaft are both fixed to the connecting piece; and

[0023] When the first hinge shaft moves to the front of the second hinge shaft, the air outlet panel is in a horizontal state with the air outlet fully opened;

[0024] When the first hinge shaft moves to the rear of the second hinge shaft, the air outlet panel is in a vertical state that completely closes the air outlet.

[0025] Optionally, when the air outlet panel is in a horizontal state, its lower surface is higher than the upper edge of the air outlet, and there is a movement gap between the rear side and the casing.

[0026] Optionally, the air conditioner indoor unit further includes:

[0027] An installation box is defined therein with an installation space for accommodating the first transmission member and the second transmission member, and a side wall of the installation box is provided with a first slide groove, which extends upward at an angle from back to front, and at least a portion of the first transmission member is slidably arranged in the first slide groove.

[0028] Optionally, the side wall of the mounting box is further provided with a second slide groove, which extends upwardly and obliquely from back to front, and the rear end of the second transmission member is slidably arranged in the second slide groove, wherein the slope of the second slide groove is greater than the slope of the first slide groove.

[0029] Optionally, the first transmission member is provided with a rack extending in the front-to-rear direction; and

[0030] The transmission mechanism further comprises:

[0031] The gear is engaged with the rack and is used for rotating in a controlled manner to drive the first transmission member to move forward and backward through the rack.

[0032] Optionally, the air conditioner indoor unit further includes:

[0033] The driving part is directly or indirectly connected to the first transmission member and is configured to drive the first transmission member to move forward and backward in a controlled manner.

[0034] The air conditioner indoor unit of the present invention connects a transmission mechanism to the air outlet panel, enabling a unique opening method in which the lower edge of the air outlet panel flips upward and outward. The air outlet panel acts as a physical barrier, redirecting airflow that would otherwise flow directly upward into the space ahead. This design encourages airflow to fully circulate indoors before returning to the air inlet, effectively alleviating or circumventing the airflow short-circuiting problem found in traditional units and significantly improving the cooling and cooling efficiency of the air conditioner.

[0035] Furthermore, the air conditioner indoor unit of the present invention utilizes a vertically staggered first and second hinge points, combined with the linear propulsion of the first transmission member and the trajectory constraint of the second transmission member, to enable the air outlet panel to flip upward around the high hinge point during its outward movement. This design avoids the air outlet panel's movement jamming caused by a single hinge point, ensuring a smoother and more stable opening process.

[0036] Furthermore, in the air conditioner indoor unit of the present invention, the first transmission member extends upward and obliquely from rear to front, enabling the first transmission member to generate a forward and upward thrust as it moves forward, thereby assisting in the upward and outward tilting of the lower edge of the air outlet panel and reducing the difficulty of rotating the air outlet panel. Furthermore, the sliding and rotation of the guide rod within the guide groove allows the second transmission member to adaptively adjust with the movement of the first transmission member while effectively constraining the motion trajectory of the second hinge point, thereby maintaining smooth opening of the air outlet panel.

For example, features illustrated or described as part of one embodiment may be used in conjunction with another embodiment to produce yet another embodiment. Therefore, the present invention is intended to cover such modifications and variations within the scope of the appended claims and their equivalents.

[0052] Refer to the following Figure 1-10 The air conditioner indoor unit 10 according to an embodiment of the present invention is described below. The terms "inside," "outside," "upper," "lower," "top," "bottom," "horizontal," and "vertical" are used to indicate positions or relationships based on those shown in the accompanying drawings. These terms are intended solely to facilitate and simplify the description of the present invention and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0053] In the description of this embodiment, it should be understood that the term "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined. When a feature "includes or comprises" one or more of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may further include other features.

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

[0055] In the description of the present embodiment, reference to terms such as "one embodiment," "some embodiments," "some examples," or "an example" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0056] Figure 1 is a schematic structural diagram of an air-conditioning indoor unit 10 according to one embodiment of the present invention. Figure 2 yes Figure 1 The schematic layout diagram of the air inlet 101 and the air outlet 102 of the air conditioner indoor unit 10 is shown. Figure 3 yes Figure 1 Schematic cross-sectional view of the air conditioner indoor unit 10 shown in FIG. Figures 1 to 3 As shown, the air conditioner indoor unit 10 may generally include a casing 100 , an air outlet panel 120 and at least one transmission mechanism 200 .

[0057] Among them, an air outlet 102 is opened in the lower area of the front side of the casing 100, an air outlet panel 120 is arranged at the air outlet 102, and a transmission mechanism 200 is arranged in the casing 100 and connected to the air outlet panel 120, and is configured to drive the air outlet panel 120 in a controlled manner, so that the lower edge of the air outlet panel 120 is turned upward and outward, thereby opening the air outlet 102.

[0058] The above structure connects the transmission mechanism 200 to the air outlet panel 120, achieving a unique opening method in which the lower edge of the air outlet panel 120 flips upward and outward. The air outlet panel 120 acts as a physical barrier, redirecting airflow that would otherwise flow directly upward into the space ahead. This design encourages airflow to fully circulate indoors before returning to the air inlet 101, effectively alleviating or circumventing the airflow short-circuiting problem found in traditional air conditioners and significantly improving the cooling / control efficiency of the air conditioner.

[0059] In this embodiment, the air inlet 101 can be provided in the upper area of the front side of the housing 100. The air inlet 101 extends laterally in the upper area of the front side of the housing 100, and the air outlet 102 extends laterally in the lower area of the front side of the housing 100, respectively for achieving front-upward air intake and front-downward air outlet of the air conditioner indoor unit 10.

[0060] When the air-conditioning indoor unit 10 needs to be installed in an area with limited space such as a cabinet, the front-up air intake and front-down air outlet method is not restricted by the top and bottom walls of the cabinet. There is no need to worry about air flow obstruction or insufficient space, which is conducive to improving the installation adaptability of the air-conditioning indoor unit 10.

[0061] In other embodiments, the air inlet 101 may also be disposed on the top of the housing 100 .

[0062] In some other embodiments, the number of the air inlet 101 may be two, and the two air inlets 101 are respectively disposed at the top of the housing 100 and the upper area of the front side of the housing 100 .

[0063] It's worth emphasizing that the present invention fundamentally solves the problem of airflow short-circuiting by virtue of its unique upward and outward opening method, the air outlet panel 120. Whether the air inlet 101 is located on the front or top of the housing 100, or even a dual air inlet 101 layout on the front and top, the air outlet panel 120, when open, forms a physical barrier, effectively preventing airflow from flowing directly upward back to the air inlet 101.

[0064] Figure 4 is a schematic assembly diagram of the transmission mechanism 200 and the air outlet panel 120 according to one embodiment of the present invention. Figure 5 is a schematic assembly diagram of a transmission mechanism 200 and an air outlet panel 120 according to another embodiment of the present invention. Figure 6 yes Figure 5 The schematic diagram of the state when the air inlet panel 110 and the air outlet panel 120 are both opened is shown. Figure 7 is a schematic diagram of a state when the air outlet panel 120 is fully closed according to an embodiment of the present invention. Figure 8 is a schematic diagram of a state when the air outlet panel 120 is fully opened according to an embodiment of the present invention. Figure 9 yes Figure 3 The schematic structural diagram of the installation box 230 shown in the first opening perspective is as follows: Figure 10 yes Figure 3 The illustrated schematic structural diagram of the installation box 230 at a second open viewing angle.

[0065] In some embodiments, the transmission mechanism 200 may include a first transmission member 210 and a second transmission member 220, wherein the front end of the first transmission member 210 forms a first hinge point with the air outlet panel 120, and the front end of the second transmission member 220 forms a second hinge point with the air outlet panel 120, with the second hinge point being located higher than the first hinge point. The first transmission member 210 is configured to move forward in a controlled manner to push the air outlet panel 120 outward, and the second transmission member 220 is configured to constrain the motion trajectory of the second hinge point during the pushing process of the air outlet panel 120, causing the air outlet panel 120 to rotate about the second hinge point to flip the bottom edge of the air outlet panel 120 upward.

[0066] The above structure, by staggering the first and second hinge points vertically, combined with the linear propulsion of the first transmission member 210 and the trajectory constraint of the second transmission member 220, allows the air outlet panel 120 to flip upward around the high hinge point during the outward push. This design avoids the stalling of the air outlet panel 120 caused by a single hinge point, ensuring a smoother and more stable opening process for the air outlet panel 120.

[0067] In some embodiments, the first transmission member 210 extends upwardly and obliquely from rear to front so as to push the air outlet panel 120 toward the front and upward during controlled forward movement. The first transmission member 210 is provided with a guide slot 212 extending downwardly and obliquely from rear to front. The rear end of the second transmission member 220 is provided with a guide rod 222. During the pushing process of the air outlet panel 120, the guide rod 222 slides and rotates within the guide slot 212, thereby constraining the motion trajectory of the second hinge point.

[0068] With this structure, the first transmission member 210 extends upward and obliquely from rear to front, generating a forward and upward thrust as it moves forward. This helps tilt the lower edge of the air outlet panel 120 upward and outward, making it easier to rotate the air outlet panel 120. Furthermore, the sliding and rotation of the guide rod 222 within the guide slot 212 allows the second transmission member 220 to adaptively adjust with the movement of the first transmission member 210 while effectively constraining the motion trajectory of the second hinge point, thereby maintaining smooth opening of the air outlet panel 120.

[0069] In some embodiments, a first hinge axis 121 and a second hinge axis 122 are provided on the inner side of the air outlet panel 120. The second hinge axis 122 is positioned higher than the first hinge axis 121, and the axes of both hinge axes are arranged along the transverse direction of the air outlet panel 120. The front end of the first transmission member 210 is provided with a first hinge hole 211, into which the first hinge axis 121 is inserted, forming a first hinge point that can rotate relative to each other. The front end of the second transmission member 220 is provided with a second hinge hole 221, into which the second hinge axis 122 is inserted, forming a second hinge point that can rotate relative to each other.

[0070] Of course, the arrangement of the hinge shaft and the hinge hole can be flexibly adjusted according to actual design requirements.

[0071] For example, a first hinge shaft 121 and a second hinge shaft 122 are respectively provided at the front ends of the first transmission member 210 and the second transmission member 220 , and a first hinge hole 211 and a second hinge hole 221 are correspondingly provided on the inner side of the air outlet panel 120 .

[0072] For another example, a first hinge shaft 121 is provided at the front end of the first transmission member 210, and a first hinge hole 211 is correspondingly provided on the inner side of the air outlet panel 120. Simultaneously, a second hinge hole 221 is provided at the front end of the second transmission member 220, and a second hinge shaft 122 is correspondingly provided on the inner side of the air outlet panel 120.

[0073] For example, a first hinge hole 211 is provided at the front end of the first transmission member 210, and a first hinge shaft 121 is provided on the inner side of the air outlet panel 120. At the same time, a second hinge shaft 122 is provided at the front end of the second transmission member 220, and a second hinge hole 221 is provided on the inner side of the air outlet panel 120.

[0074] In some embodiments, a connecting member 140 is provided on the inner side of the air outlet panel 120, and the first hinge shaft 121 and the second hinge shaft 122 are both fixed to the connecting member 140. Furthermore, when the first hinge shaft 121 moves directly in front of the second hinge shaft 122, the air outlet panel 120 is in a horizontal position, fully opening the air outlet 102. When the first hinge shaft 121 moves directly below the second hinge shaft 122, the air outlet panel 120 is in a vertical position, fully closing the air outlet 102.

[0075] In one example, the connector 140 includes a panel base 141 and a hinge bracket 142. The panel base 141 is fixed to the air outlet panel 120 or is integrally formed with the air outlet panel 120. The hinge bracket 142 is a separate component that is mutually engaged with the panel base 141. The first hinge shaft 121 and the second hinge shaft 122 are both fixed to the hinge bracket 142 or are integrally formed with the hinge bracket 142.

[0076] It can be understood that the panel base 141 and the hinged bracket 142 have a certain combined length, which is equivalent to optimizing the rotational dynamic model of the air outlet panel 120 by extending the lever arm. When rotating the air outlet panel 120 from a vertical position to a horizontal position, this structure can shorten the forward movement distance required by the first transmission member 210, which directly reduces the front and rear space occupied by the transmission mechanism 200.

[0077] In this embodiment, when the air outlet panel 120 is in a horizontal state, the lower surface of the air outlet panel 120 is higher than the upper edge of the air outlet 102 to ensure that the airflow after heat exchange can be blown out smoothly. There is a movement gap between the rear side of the air outlet panel 120 and the casing 100 to provide sufficient space for the movement of the air outlet panel 120.

[0078] In some embodiments, the air conditioner indoor unit 10 may further include an installation box 230, which defines an installation space for accommodating the first transmission member 210 and the second transmission member 220. By accommodating the first transmission member 210 and the second transmission member 220 in the installation box 230, it is possible to avoid space clutter and component interference caused by the random arrangement of the first transmission member 210 and the second transmission member 220 within the housing 100.

[0079] The modular installation method makes the internal structure of the air-conditioning indoor unit 10 more regular, which is not only conducive to the rapid positioning and installation of components during production and assembly, but also leaves a reasonable layout space for other components, thereby improving the space utilization rate of the entire machine; at the same time, the closed installation box 230 can effectively protect the transmission parts from dust and debris, reduce the risk of components being damaged by external factors, and enhance the long-term reliability of the transmission.

[0080] In some embodiments, the sidewall of the mounting box 230 may be provided with a first slide groove 233, which extends obliquely upward from back to front, and at least a portion of the first transmission member 210 is slidably disposed within the first slide groove 233. Thus, the first slide groove 233 can provide a stable motion track for the first transmission member 210, ensuring that it moves along a predetermined path while pushing the air outlet panel 120, thereby preventing deviation or shaking caused by uneven force.

[0081] In one example, a sliding pin 213 is provided on one side of the first transmission member 210 adjacent to the first sliding slot 233, and the sliding pin 213 is inserted into the first sliding slot 233. When the first transmission member 210 moves forward in a controlled manner, the sliding pin 213 slides precisely along the track of the first sliding slot 233.

[0082] In some embodiments, the side wall of the mounting box 230 may also be provided with a second slide groove 234, which extends upward at an angle from back to front, and the rear end of the second transmission member 220 is slidably set in the second slide groove 234, wherein the slope of the second slide groove 234 is greater than the slope of the first slide groove 233.

[0083] It can be understood that the first transmission member 210 is driven to move by the air outlet panel 120. The slope of the second chute 234 is greater than the slope of the first chute 233. This means that under the same horizontal movement distance, the second transmission member 220 has a greater vertical displacement than the first transmission member 210. This design creates a speed difference between the two transmission members during movement, thereby driving the air outlet panel 120 to complete a combined movement and rotation, ultimately achieving the upward and outward turning of the lower edge.

[0084] In one example, the installation box 230 includes a first box body 231 and a second box body 232. The first box body 231 and the second box body 232 can be snapped together in a horizontal direction and fixed together by means of clips, slots, or bolts to define an installation space. The first slide groove 233 can be provided only in the side wall of the first box body 231, and the second slide groove 234 can be provided in the side wall of the first box body 231 and the side wall of the second box body 232. The guide rod 222 is disposed in the guide groove 212, and its two ends are slidably connected to the second slide groove 234.

[0085] When the air outlet panel 120 is in a fully closed state, the guide rod 222 stops at the front end of the guide groove 212. During the opening process of the air outlet panel 120, as the first transmission member 210 moves forward, the guide rod 222 moves backward and upward in the guide groove 212 until the guide rod 222 stops at the rear end of the guide groove 212, and the air outlet panel 120 is in a fully open state.

[0086] In some embodiments, the first transmission member 210 is provided with a rack 214 extending in the front-to-back direction, and the transmission mechanism 200 further includes a gear 240 , which is engaged with the rack 214 for controlled rotation to drive the first transmission member 210 to move forward and backward through the rack 214 .

[0087] In some embodiments, the air conditioning indoor unit 10 further includes a driving unit 250 , which is directly or indirectly connected to the first transmission member 210 and configured to controllably drive the first transmission member 210 to move forward and backward.

[0088] In one example, the driving unit 250 is a motor, and the output shaft of the motor is fixedly connected to the axle of the gear 240. During the rotation of the motor, the gear 240 cooperates with the rack 214 to drive the first transmission member 210 to move forward and backward.

[0089] In another example, the driving part 250 is a cylinder, and the piston rod of the cylinder is connected to the first transmission member 210. During the extension and retraction process, the piston rod of the cylinder drives the first transmission member 210 to move forward and backward.

[0090] In some embodiments, there are two transmission mechanisms 200 , and the two transmission mechanisms 200 are respectively connected to two lateral sides of the air outlet panel 120 to jointly drive the air outlet panel 120 to open or close.

[0091] In some embodiments, the air conditioner indoor unit 10 may further include an air inlet panel 110 , which is hinged to the housing 100 and is used to controllably open or close the air inlet 101 .

[0092] When in an idle state, the air inlet panel 110 can be closed to prevent dust and debris from entering the interior of the air conditioning indoor unit 10. When adjusting the indoor air, the air inlet panel 110 can be opened to allow air to enter normally and ensure the normal operation of the air conditioning indoor unit 10.

[0093] The air inlet panel 110 is controlled to open, and can be in the form of an upper edge turned downward and outward. In this way, after the air inlet panel 110 is opened, indoor air can flow into the air inlet 101 from above and both sides of the air inlet panel 110, reducing the suction force on the airflow at the air outlet 102.

[0094] It should be noted that although the air inlet panel 110 opens with its upper edge tilted downward and outward, effectively distributing the incoming air and reducing interference with the airflow at the air outlet 102, this does not mean that the air outlet panel 120 can be omitted. In fact, the air outlet panel 120 plays an irreplaceable and critical role. If the air outlet panel 120 is removed, some of the airflow from the air outlet 102 may still flow back upward directly along the inclined surface of the air inlet panel 110, causing the airflow to re-enter the air inlet 101 without fully mixing with the indoor air and undergoing heat exchange.

[0095] In this embodiment, the housing 100 may be a rectangular shell, with the air inlet 101 and air outlet 102 both extending laterally in a long strip. The air intake area of the air inlet 101 is larger than the air outlet area of the air outlet 102. This allows full utilization of the front space of the housing 100, allowing the air inlet 101 and air outlet 102 to occupy a larger area, thereby improving air flow efficiency. Furthermore, the long strip facilitates even air distribution, avoiding the problem of excessive or insufficient airflow in certain areas.

[0096] Because the air inlet area of the air inlet 101 is larger than the air outlet area of the air outlet 102, even if the wind speed at the air inlet 101 is low, sufficient air volume can be ensured to enter the housing 100, and after being processed, it can be discharged at a higher wind speed from the air outlet 102. At the same time, the larger area of the air inlet 101 can also reduce the local wind speed at the air inlet 101, reducing noise and vibration, and improving the comfort and stability of the air conditioner indoor unit 10.

[0097] In this embodiment, a panel frame 130 is provided on the front side of the housing 100, and the air inlet 101 and the air outlet 102 are provided on the panel frame 130. The left-right length of the air inlet 101 is equal to the left-right length of the air outlet 102, and the vertical height of the air inlet 101 is greater than the vertical height of the air outlet 102, so that the air intake area of the air inlet 101 is larger than the air outlet area of the air outlet 102.

[0098] At this point, those skilled in the art will recognize that, although a number of 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 may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
