After the cabinet door is opened, the air inlet and outlet on the front side of the embedded air conditioner indoor unit are exposed for air intake and exhaust.

[0004] However, technicians found that the air conditioning energy efficiency of the embedded indoor air conditioner was always low, and no good solution could be found. Utility Model Content

[0005] The purpose of the present utility model is to provide a built-in air-conditioning indoor unit that overcomes the above problems or at least partially solves the above problems.

[0006] The purpose of the utility model is to improve the air conditioning energy efficiency of a built-in air-conditioning indoor unit.

[0007] In order to solve the above technical problems, the present invention provides a built-in air conditioner indoor unit, which includes:

[0008] The housing has an air inlet for air intake and an air outlet for air discharge on a first side surface thereof, wherein the air inlet and the air outlet are arranged side by side; and

[0009] A first panel is movably mounted on the housing; and

[0010] The first panel has a closed position for enclosing the air inlet, and has an open position between the air inlet and the air outlet, so that in the open position, the air inlet is allowed to enter, and the air flow in the air inlet is isolated from the air flow out of the air outlet to avoid mixing of the air flow in and the air flow out.

[0011] Optionally, the first side of the first panel is rotatably mounted on the housing; and

[0012] The first side is adjacent to a side of the air inlet adjacent to the air outlet, so that when the first panel is in the open position, the first side is located between the air inlet and the air outlet.

[0013] Optionally, the air inlet is located above the air outlet; and

[0014] The first side is a bottom side of the first panel.

[0015] Optionally, the first panel is configured so that when it is in the open position, the angle between it and the first side surface is between 20° and 60°.

[0016] Optionally, the embedded air conditioner indoor unit further includes:

[0017] At least one driving device, each of which is installed between the housing and the first panel and is used to controllably drive the first panel to move between the open position and the closed position.

[0018] Optionally, each of the driving devices includes:

[0019] A drive motor, fixedly installed inside the housing; and

[0020] a connecting rod, a first end of which is fixedly connected to the rotating shaft of the driving motor and a second end of which is slidably mounted on the first panel;

[0021] When the driving motor drives the connecting rod to swing back and forth, the second end of the connecting rod moves toward or away from the air outlet, thereby driving the first panel to close or open the air inlet.

[0022] Optionally, the inner side of the first panel facing the air inlet has at least one sliding groove; and

[0023] A roller is installed on the second end of each connecting rod, and the roller can be slidably inserted into the sliding groove so that when the connecting rod swings, the second end of the connecting rod slides along the length direction of the sliding groove, thereby driving the first panel to close or open the air inlet.

[0024] Optionally, each of the rollers is rotatably mounted on the second end of the connecting rod.

[0025] Optionally, the embedded air conditioner indoor unit further includes:

[0026] a windshield, the windshield being rotatably mounted on the housing to open and close the air outlet and guide the flow direction of the outlet airflow; and

[0027] When the wind shield is in a position closing the air outlet, it is located between the air inlet and the air outlet, thereby separating the inlet airflow of the air inlet from the outlet airflow of the air outlet.

[0028] Optionally, the embedded air-conditioning indoor unit is embedded, for being embedded in a preset cavity; and

[0029] The air inlet and the air outlet are opened toward the chamber to exchange air with the external space of the chamber.

[0030] Through research, the inventors of the present utility model have discovered that the reason why existing embedded air-conditioning indoor units have low air conditioning efficiency is related to the air intake method of the embedded air-conditioning indoor units. The embedded air-conditioning indoor units adopt a front airflow form, and the air inlet and air outlet are arranged adjacent to each other and very close to each other. This causes a portion of the outlet air flow to mix with the inlet air flow and flow back into the casing from the air inlet. Taking the cooling mode as an example, the temperature of these outlet air flows is relatively low in itself, and their mixing with the inlet air flow will cause the overall temperature of the inlet air flow to become lower, lowering the heat exchange rate between the inlet air flow and the heat exchanger, causing the heat exchanger to be unable to fully exert its heat exchange capacity, resulting in a decrease in its heat exchange efficiency, and thus a decrease in the air conditioning efficiency.

[0031] The embedded air conditioner indoor unit of the present invention is specially designed with a first panel. The first panel has a closed position that seals the air inlet and an open position between the air inlet and the air outlet. In the open position, the first panel opens the air inlet to allow air to enter the air inlet and isolates the inlet airflow from the outlet airflow to prevent the inlet and outlet airflows from mixing, thereby preventing the heat exchange airflow from mixing with the inlet airflow, ensuring the heat exchange efficiency of the heat exchanger, and thus improving the energy efficiency of the air conditioner. In the closed position, the first panel closes the air inlet, preventing external dust and impurities from entering the interior of the housing through the air inlet, thereby improving the cleanliness of the interior of the housing.

[0032] Furthermore, the embedded air conditioner indoor unit of the present invention includes a windshield, which is rotatably mounted on the housing to open and close the air outlet and guide the flow of the outlet air. When the windshield is in the position that closes the air outlet, it is located between the air inlet and the air outlet, thereby separating the airflow from the air inlet from the airflow from the air outlet, preventing the heat exchange airflow from mixing with the airflow, ensuring the heat exchange efficiency of the heat exchanger, and thus improving the energy efficiency of the air conditioner.

[0048] An embodiment of the utility model provides a built-in air-conditioning indoor unit.

[0049] A built-in air conditioner indoor unit is the indoor portion of a split-type air conditioner or the indoor terminal unit of a central air conditioner. It is used to condition the indoor air. Specifically, this includes adjusting the air temperature, humidity, and air quality, humidifying and dehumidifying the indoor air, and introducing fresh air. An air conditioner can consist of an evaporator, condenser, compressor, throttling device, and other necessary components to form a vapor compression refrigeration cycle system. This system outputs cold / hot air through a fan to achieve cooling and heating of the indoor environment.

[0050] Figure 1 This is a structural diagram of an embedded air-conditioning indoor unit according to an embodiment of the present invention; Figure 2 yes Figure 1 The schematic diagram of the embedded air conditioner indoor unit is shown when the first panel 20 is in the open position; Figure 3 yes Figure 2 A schematic side view of a flush-mounted air conditioner indoor unit is shown.

[0051] like Figures 1 to 3 As shown, the embedded air-conditioning indoor unit of the embodiment of the present invention may generally include a casing 10 and a first panel 20 .

[0052] An air inlet 11 for air intake and an air outlet 12 for air discharge are formed on a first side surface of the housing 10 . The air inlet 11 and the air outlet 12 are arranged side by side.

[0053] The embedded air conditioner indoor unit is embedded and is used to be embedded in a preset chamber. The air inlet 11 and the air outlet 12 are opened towards the chamber to exchange air with the external space of the chamber.

[0054] The cavity may be a cavity of a cabinet. The cabinet may include a cabinet body and a cabinet door, wherein the cabinet body defines the cavity and has an opening, and the cabinet door is movably arranged on the cabinet body for opening and closing the opening.

[0055] The first panel 20 is movably mounted on the housing 10. The first panel 20 has a closed position for sealing the air inlet 11. Figure 1 , and has an open position between the air inlet 11 and the air outlet 12, such as Figure 2 Thus, when in the open position, air is allowed to enter the air inlet 11 and the air flow from the air inlet 11 is isolated from the air flow from the air outlet 12 to prevent the air flow from mixing with the air flow.

[0056] like Figures 1 to 3 As shown, the aforementioned first side surface is the front surface. Of course, in other embodiments, the aforementioned first side surface may also be a lateral side surface, a lower surface or an upper surface, which is not limited in the present invention.

[0057] The housing 10 is used to accommodate the main components of the embedded air conditioner indoor unit, including a fan, an indoor heat exchanger, an electronic control module, and the like.

[0058] The housing 10 is used to be embedded in a cabinet or other structure with a cavity, with its front side exposed to the outside. The shape of the housing 10 is not limited in this embodiment. Figures 1 to 3 The case 10 is shown as a horizontally long strip. In addition, the case 10 can also be an upright column, square or other shapes. The case 10 has a top plate constituting its top structure and a front plate constituting its front structure, and the top plate and the front plate face upward and forward respectively.

[0059] The fan is disposed within the housing 10 and is configured to draw air from the outside of the housing 10 into the housing 10 through the air inlet 11, thereby forming an inlet airflow. The present invention does not limit the type of fan. Specifically, the fan may be a cross-flow type, an axial flow type, a centrifugal type, or other types.

[0060] The indoor heat exchanger is disposed within the housing 10 and is configured to exchange heat with the incoming airflow within the housing 10, forming a heat exchange airflow. When the air conditioner is operating in cooling mode, the heat exchange airflow is cold air. When the air conditioner is operating in heating mode, the heat exchange airflow is hot air. Of course, the air conditioner may have only cooling functions, or both cooling and heating functions.

[0061] The indoor heat exchanger, the throttling device, the compressor arranged in the outdoor unit of the air conditioner, the outdoor heat exchanger and other refrigeration elements are connected through pipelines to form a vapor compression refrigeration cycle system.

[0062] The compressor is typically a rolling rotor compressor. The throttling device may include a capillary tube or an electronic expansion valve. For heat pump air conditioners, the vapor compression refrigeration cycle also includes a four-way valve to switch between cooling and heating modes.

[0063] For heat pump air conditioners, the indoor heat exchanger acts as an evaporator in cooling mode and as a condenser in heating mode.

[0064] An air duct is formed inside the housing 10, the outlet of which is connected to the air outlet 12, allowing the heat exchange air within the housing 10 to be blown out of the housing 10 through the air outlet 12. Under the action of the fan, indoor air enters the housing 10 through the air inlet 11, completes forced convection heat exchange with the indoor heat exchanger, and forms a heat exchange airflow, which is guided by the air duct 15 and blown out of the air outlet 12 to the indoor environment.

[0065] Through research, the inventors of this utility model discovered that the low air conditioning efficiency of existing built-in air conditioner indoor units is related to their air intake method. Built-in air conditioner indoor units use a front-end airflow system, with the air inlet 11 and air outlet 12 positioned adjacent to each other and very close together. This causes a portion of the outgoing airflow to mix with the incoming airflow, flowing back through the air inlet 11 and into the housing 10.

[0066] Taking the cooling mode as an example, the temperature of these outlet air flows is relatively low in itself. When the outlet air flows into the inlet air flow, the overall temperature of the inlet air flow will become lower, which will reduce the heat exchange between the inlet air flow and the heat exchanger. As a result, the heat exchanger cannot fully utilize its existing heat exchange capacity, resulting in a decrease in its heat exchange efficiency, which in turn leads to a decrease in the functional energy efficiency of the air conditioner.

[0067] To address this technical problem, the embedded air conditioner indoor unit of the present invention is specially designed with a first panel 20. The first panel 20 has a closed position that seals the air inlet 11, and an open position between the air inlet 11 and the air outlet 12. In the open position, the first panel 20 opens the air inlet 11 to allow air to enter the air inlet 11, and isolates the incoming airflow from the air inlet 11 from the outgoing airflow from the air outlet 12 to prevent the incoming airflow and the outgoing airflow from mixing, thereby preventing the heat exchange airflow from mixing with the incoming airflow, ensuring the heat exchange efficiency of the heat exchanger, and thus improving the energy efficiency of the air conditioner. In the closed position, the first panel 20 closes the air inlet 11, preventing external dust and impurities from entering the interior of the housing 10 through the air inlet 11, thereby improving the cleanliness of the interior of the housing 10.

[0068] Furthermore, the embedded air conditioner indoor unit of the embodiment of the present invention can also adjust the air intake volume of the air inlet 11 by adjusting the opening of the first panel 20, thereby achieving adjustable air intake volume.

[0069] In some embodiments of the present invention, the first side 201 of the first panel 20 is rotatably mounted on the housing 10. Furthermore, the first side 201 is adjacent to a side of the air inlet 11 that is adjacent to the air outlet 12. When the first panel 20 is in the open position, the first side 201 is located between the air inlet 11 and the air outlet 12, and closer to the housing 10, thereby more completely isolating the inlet and outlet airflows.

[0070] Preferably, reference Figure 2 and Figure 3 , the air inlet 11 can be located above the air outlet 12, and the first side 201 is the bottom side of the first panel 20. The bottom side is adjacent to the top side of the air outlet 12.

[0071] The top edge 202 of the first panel 20 is a free end. Thus, the first panel 20 as a whole rotates about the first edge 201. This allows the relatively low-density, hotter indoor air to float more freely above the room during cooling mode, making it easier for the air inlet 11 located further up to enter the housing 10.

[0072] Furthermore, the first panel 20 is configured such that, when in the open position, the angle a formed between the first panel 20 and the first side surface is between 20° and 60°, that is, 20°≤a≤60°, for example, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, or 60°. Preferably, 30°≤a≤50°.

[0073] If a is too large, it will take up too much space. If a is too small, it will easily affect the air intake, thereby affecting the operating capacity of the air conditioner. The embodiment of the utility model reasonably limits the range of a to minimize the impact on the air intake of the air conditioner.

[0074] The embodiment of the utility model enables the first panel 20 to be rotatably arranged, and its installation structure is simpler, lower in cost, and more reliable.

[0075] Of course, in other embodiments of the present invention, the first panel 20 can be mounted on the housing 10 so as to be translatable, or mounted on the housing 10 in a planar motion manner, where the planar motion is a composite motion of translation and rotation. Those skilled in the art can reasonably design the motion method and motion path of the first panel 20, and no further details will be given here.

[0076] Figure 4 yes Figure 3 A magnified view of point A; Figure 5 yes Figure 1 The structure diagram of the embedded air conditioner indoor unit is shown after the first panel 20 is removed.

[0077] In some embodiments of the present invention, Figures 3 to 5 As shown, the embedded air conditioner indoor unit further includes at least one driving device 40. Each driving device 40 is installed between the casing 10 and the first panel 20, and is used to controllably drive the first panel 20 to move between an open position and a closed position.

[0078] The driving device 40 can be connected to the controller of the air conditioner to receive control from the controller. When the air conditioner is turned on, the controller can control the driving device 40 to operate and drive the first panel 20 from the closed position to the open position. When the air conditioner is turned off, the controller can control the driving device 40 to operate and drive the first panel 20 from the open position to the closed position.

[0079] The number of the driving device 40 may be one or more.

[0080] For example, for Figures 1 to 5 The long first panel 20 shown can be provided with two driving devices 40 , so that the two driving devices 40 are respectively connected to the two lateral ends of the first panel 20 , and the two driving devices 40 move synchronously.

[0081] Specifically, in some embodiments of the present invention, Figures 3 to 5 As shown, each driving device 40 includes a driving motor 41 and a connecting rod 42 .

[0082] The drive motor 41 is fixedly mounted within the housing 10. The first end of the connecting rod 42 is fixedly connected to the rotating shaft of the drive motor 41, and the second end is slidably mounted on the first panel 20. Together, the connecting rod 42 and the first panel 20 form a slider-crank mechanism. When the drive motor 41 drives the connecting rod 42 to swing back and forth, the second end of the connecting rod 42 moves toward or away from the air outlet 12, thereby driving the first panel 20 to close or open the air inlet 11.

[0083] like Figure 5 As shown, the first side panel of the housing 10 may be provided with a clearance slot 13 , the driving motor 41 is located inside the housing 10 , and the connecting rod 42 extends to the outside of the housing 10 through the clearance slot 13 .

[0084] The driving motor 41 is preferably a stepping motor capable of controlled forward and reverse rotation, so as to facilitate fine adjustment of the rotation angle of the first panel 20 .

[0085] Specifically, if Figure 3 and Figure 4 As shown, the inner side surface of the first panel 20 facing the air inlet 11 has at least one slide groove 210. A roller 43 is mounted on the second end of each connecting rod 42. The roller 43 is slidably inserted into the slide groove 210. When the connecting rod 42 swings, the second end of the connecting rod 42 slides along the length of the slide groove 210, thereby driving the first panel 20 to close or open the air inlet 11.

[0086] like Figure 4 As shown, a long strip 21 can be provided on the inner side of the first panel 20. The long strip 21 is spaced apart from the inner side of the first panel 20, and the space between the long strip 21 and the first panel 20 forms a chute 210. Both ends of the long strip 21 are bent toward the first panel 20 to be connected to the first panel 20.

[0087] Furthermore, the long strip board 21 and the first panel 20 can be formed as an integral piece to reduce costs.

[0088] In some embodiments, each roller 43 can be rotatably mounted on the second end of the connecting rod 42. In this way, when the driving motor 41 drives the first panel 20 to rotate, the roller 43 rolls in the sliding groove 210, and its movement is smoother and quieter.

[0089] Of course, in other embodiments, the roller 43 may be fixedly connected to the second end of the connecting rod 42 , and when the driving motor 41 drives the first panel 20 to rotate, the roller 43 slides in the sliding groove 210 .

[0090] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the embedded air conditioner indoor unit further includes a wind shield 50 .

[0091] The windshield 50 is rotatably mounted on the housing 10 to open and close the air outlet 12 and guide the flow of the outlet air. When the windshield 50 is in the position to close the air outlet 12, it is located between the air inlet 11 and the air outlet 12, thereby separating the airflow from the air inlet 11 from the airflow from the air outlet 12.

[0092] When the windshield 50 is in the position of closing the air outlet 12, as shown in FIG. Figure 2 It is located between the air inlet 11 and the air outlet 12, thereby better separating the inlet airflow of the air inlet 11 from the outlet airflow of the air outlet 12, avoiding the heat exchange airflow from mixing with the inlet airflow, ensuring the heat exchange efficiency of the heat exchanger, and thus improving the energy efficiency of the air conditioner.

[0093] For example Figure 2 As shown, the air outlet 12 and the air inlet 11 are opened on the front side of the housing 10, and the air outlet 12 is located below the air inlet 11. The wind shield 50 is rotatably mounted on the housing 10 around a transverse axis so as to be rotated to a wind shielding position extending forward from the upper side of the air outlet 12, thereby separating the inlet air flow from the heat exchange air flow to prevent the outlet air flow from mixing with the inlet air flow, as shown in FIG. Figure 2 .

[0094] like Figure 2 As shown, the wind deflector 50 can be extended horizontally when in the wind-blocking position. The wind deflector 50 can also have a position to close the air outlet 12, such as Figure 1 .like Figure 2 As shown, the rotation axis of the wind deflector 50 can be located at its end and adjacent to the upper edge of the air outlet 12 so as to rotate between the closed position and the wind blocking position. In addition, the wind outlet angle and air volume of the air outlet 12 can also be adjusted by adjusting the rotation angle of the wind deflector 50.

[0095] Furthermore, the built-in air conditioner indoor unit also includes a deflector. The end of the deflector is rotatably mounted on the housing 10, with its rotation axis extending laterally and near the bottom of the air outlet 12, for adjusting the airflow direction of the air outlet 12. In this way, the wind deflector 50 and the deflector form a "split" configuration, and the two can adjust the airflow direction and volume in conjunction with or independently of each other.

[0096] In some embodiments, as Figure 5 As shown, at least one filter 18 may be provided at the air inlet 11 , and each filter 18 is used to filter the air entering the housing 10 through the air inlet 11 to remove dust and impurities therein.

[0097] 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.
