[0002] The indoor unit of the air conditioner is generally provided with an air outlet for blowing cold air or hot air into the indoor environment to regulate the indoor ambient air.

[0003] When the air conditioner is running, if a person is close to the air conditioner, the cold / hot air will blow directly on the person, which may cause discomfort. However, when the person is far away from the air conditioner, the air conditioner hopes that the air conditioner can deliver air over a long distance. Therefore, how to meet the air supply needs of users has become a technical problem that needs to be solved urgently in the air conditioning industry. Summary of the invention

[0011] Optionally, each of the driving mechanisms is connected to the first orifice plate, and a positioning portion is provided at an edge of the second orifice plate;

[0012] The casing is provided with a first stopper and a second stopper; the air conditioner indoor unit is configured as follows:

[0013] When the first orifice plate and the second orifice plate move to the wind shielding position in the connected state, the positioning portion is blocked by the first stop portion to stop the second orifice plate from moving, so that the first orifice plate continues to move to the staggered state;

[0014] When the first orifice plate and the second orifice plate move to the open position in the offset state, the positioning portion is blocked by the second stop portion to stop the second orifice plate from moving, so that the first orifice plate continues to move to the connected state.

[0015] Optionally, a first sliding column and a second sliding column are provided at the end of the first orifice plate;

[0016] The housing is provided with a first slide groove and a second slide groove;

[0017] When the driving mechanism drives the first orifice plate to move, the first sliding post slides in the first sliding groove, and the second sliding post slides in the second sliding groove.

[0018] Optionally, when the first orifice plate and the second orifice plate are in the open position and in the connected state, the first sliding post and the second sliding post abut against one end of the first sliding groove and the second sliding groove respectively;

[0019] When the first orifice plate and the second orifice plate are in the wind-shielding position and in the staggered state, the first sliding column and the second sliding column respectively abut against the other ends of the first sliding groove and the second sliding groove.

[0020] Optionally, a slide rail is fixedly arranged in the housing;

[0021] The first sliding groove, the second sliding groove, the first stopper and the second stopper are all formed on the sliding rail.

[0022] Optionally, both ends of the first orifice plate respectively have first flanges bent toward the inner side of the housing;

[0023] Both ends of the second orifice plate respectively have second flanges bent toward the inner side of the housing;

[0024] The second orifice plate is attached to the inner side of the first orifice plate, and the two second flanges are attached to the inner sides of the two first flanges respectively;

[0025] The positioning portion is arranged on the second flange and extends out through the first clearance hole formed in the first flange;

[0026] At least one mounting portion extends from the inner side of the first orifice plate, and each of the mounting portions extends out through a second clearance hole formed in the second orifice plate to be connected to one of the driving mechanisms.

[0027] Optionally, when the first orifice plate and the second orifice plate are in the connected state and the offset state, the positioning parts are respectively abutted against two opposite ends of the first relief hole.

[0028] Optionally, each of the driving mechanisms is a gear rack mechanism, which includes a motor, a gear and a rack;

[0032] Optionally, when the first orifice plate and the second orifice plate are in the communicating state, each of the first through holes is opposite to each of the second through holes, and the radii of the opposite first through holes and second through holes are equal.

[0033] The air conditioner indoor unit of the present invention has a first orifice plate and a second orifice plate which are arranged in a superimposed manner. The first orifice plate and the second orifice plate can move together or relatively to each other, so that the air conditioner indoor unit has a variety of air supply modes. For example, the first orifice plate and the second orifice plate can be moved to an open position to open the air outlet so that the air outlet is completely unblocked by them, so that the air supply distance of the air supply airflow is farther, forming a long-distance air supply mode. The first orifice plate and the second orifice plate can also be moved to a wind-shielding position and to a connected state to block the air outlet and connect a plurality of first through holes and a plurality of second through holes so that the air supply airflow flows out through the through holes, so that the airflow is fine and comfortable, forming a breeze mode. When the air conditioner indoor unit is turned off, the first orifice plate and the second orifice plate can be moved to a wind-shielding position and relatively moved to a staggered state so that a plurality of first through holes and a plurality of second through holes are staggered, so that the first orifice plate and the second orifice plate block the air outlet and cannot be ventilated, thereby playing a dust-proof role.

[0034] Furthermore, the air conditioner indoor unit of the present invention is provided with a first stopper and a second stopper in the casing. When the first orifice plate and the second orifice plate move to the wind-shielding position / closed position, the first stopper / the second stopper stops the second orifice plate to stop it, and then the first orifice plate is allowed to continue to move, so that it can be switched to the staggered state / connected state. The present invention does not need to provide a separate driving mechanism for each orifice plate, but only needs to drive the first orifice plate to drive the second orifice plate to move, and the timely stopping of the second orifice plate by the two stoppers realizes the switching of the staggered / connected state of the two orifice plates. The structure is very clever, and the driving mechanism is simplified.

A person skilled in the art should be able to understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0053] The present invention provides an indoor unit of an air conditioner. The indoor unit of an air conditioner is the indoor part of a split air conditioner or the indoor terminal model of a central air conditioner, and is used to adjust the indoor air, including adjusting the temperature, humidity, and air quality of the air, humidifying and dehumidifying the indoor air, introducing fresh air, and the like. The air conditioner can be composed of an evaporator, a condenser, a compressor, a throttling device, and other necessary components to form a vapor compression refrigeration cycle system, so as to output cold air / hot air through an indoor fan to achieve cooling and heating of the indoor environment. The indoor unit of the embodiment of the present invention can be a vertical indoor unit of an air conditioner, such as Figures 1 to 13 In addition, the air-conditioning indoor unit of the embodiment of the present invention may also be a wall-mounted air-conditioning indoor unit or an indoor unit of other forms.

[0054] Figure 1is a schematic front view of an air conditioner indoor unit according to an embodiment of the present invention when the first orifice plate 30 and the second orifice plate 40 are in an open position; Figure 2 yes Figure 1 The schematic diagram of the air conditioner indoor unit shown is when the first orifice plate 30 and the second orifice plate 40 are in the wind-blocking position and in the connected state; Figure 3 yes Figure 1 The diagram shows an indoor unit of an air conditioner when the first orifice plate 30 and the second orifice plate 40 are in a wind-shielding position and in a staggered state.

[0055] like Figures 1 to 3 As shown, the indoor unit of the air conditioner according to the embodiment of the present invention may generally include a casing 10 , a first orifice plate 30 , a second orifice plate 40 and at least one driving mechanism 50 .

[0056] The housing 10 constitutes the supporting structure of the indoor unit of the air conditioner and defines a cavity to accommodate the main structure of the indoor unit of the air conditioner, such as an evaporator, a fan, etc. The housing 10 may include a panel for constituting the appearance of the indoor unit of the air conditioner, and may also include a frame covered by the panel to support the internal structure of the air conditioner structure, an air outlet frame 15, etc., which are all well known to technicians and will not be described in detail here.

[0057] The housing 10 is provided with an air inlet (not shown, but may be provided at the rear side and / or both lateral sides of the housing 10) and an air outlet 12. The air inlet is used to introduce indoor air, which forms a heat exchange airflow after the indoor air exchanges heat with the evaporator in the housing 10, and then flows to the air outlet 12 under the action of the indoor fan. The air outlet 12 is used to blow the conditioned airflow (heat exchange airflow, purified airflow or fresh airflow, etc.) in the housing 10 to the indoor environment to regulate the indoor ambient air.

[0058] like Figures 1 to 3 , Fig.10 and Fig.11 As shown, the first orifice plate 30 and the second orifice plate 40 are stacked in the thickness direction, which refers to the thickness direction of the first orifice plate 30 and the second orifice plate 40. One side surface (large surface) of the first orifice plate 30 is attached to one side surface of the second orifice plate 40 to form a double-layer plate structure. The first orifice plate 30 is provided with a plurality of first through holes 301, and the second orifice plate 40 is provided with a plurality of second through holes 401 (refer to Fig.10 , Fig.11 For example Fig.11 As shown, a plurality of first through holes 301 may be arranged in a matrix on the first orifice plate 30, and a plurality of second through holes 401 may be arranged in a matrix on the second orifice plate 40. The opening ratio of the first orifice plate 30 and the second orifice plate 40 may be between 20% and 40%.

[0059] The driving mechanism 50 is used to drive the first orifice plate 30 and the second orifice plate 40 to move. The number of the driving mechanisms 50 may be one or more. Since the air outlet 12 is usually arranged in a long strip shape (the air outlet of the vertical air conditioner indoor unit is mostly vertical strip shape, and the air outlet of the wall-mounted air conditioner indoor unit is mostly horizontal strip shape), the first orifice plate 30 and the second orifice plate 40 are also correspondingly long strip shape, so it is preferred to set two driving mechanisms 50, respectively used to drive the two ends of the length direction of the first orifice plate 30 (and the second orifice plate 40). When two driving mechanisms 50 are set, their movements are in step. Of course, three or more driving mechanisms 50 may also be set.

[0060] The driving mechanism 50 is used to drive the first orifice plate 30 and the second orifice plate 40 to an open position (such as Figure 1 ) or close the wind shielding position of the air outlet 12 (such as Figure 2 , Figure 3 ). In addition, the first orifice plate 30 and the second orifice plate 40 are configured to be relatively movable so as to have a communication state in which the plurality of first through holes 301 communicate with the plurality of second through holes 401 (such as Figure 2 ), and a staggered state in which the plurality of first through holes 301 and the plurality of second through holes 401 are staggered (such as Figure 3 ).like Figure 1 As shown, for a vertical air conditioner indoor unit, when the first orifice plate 30 and the second orifice plate 40 are in the open position, they are located at the lateral side (left or right) of the air outlet 12 .

[0061] The air conditioner indoor unit of the embodiment of the present invention has multiple air supply modes. The first orifice plate 30 and the second orifice plate 40 move to the open position to open the air outlet 12, so that the air outlet 12 is completely unobstructed, so that the air supply distance of the air supply airflow is longer, forming a long-distance air supply mode, such as Figure 1 The first orifice plate 30 and the second orifice plate 40 move to the wind-shielding position and move to the connected state, so that the plurality of first through holes 301 and the plurality of second through holes 401 are connected, so that the air supply air flows out through the through holes, making the air flow fine and comfortable, forming a breeze mode, such as Figure 2 When the air conditioner is turned off, the first orifice plate 30 and the second orifice plate 40 can be moved to the wind-blocking position and relatively moved to a staggered state, so that the plurality of first through holes 301 and the plurality of second through holes 401 are staggered, thereby preventing ventilation. Figure 3 , so that the first orifice plate 30 and the second orifice plate 40 shield the air outlet 12 and prevent air from coming out, thereby playing a dust-proof role.

[0062] In some embodiments, when the first orifice plate 30 and the second orifice plate 40 are in a connected state, each first through hole 301 is opposite to each second through hole 401, and the radii of the first through holes 301 and the second through holes 401 opposite to each other are equal. Fig.11 .

[0063] Figure 4 is a schematic diagram of the first orifice plate 30 and the second orifice plate 40 when they are in an open position; Figure 5 yes Figure 4 A magnified image of point A; Figure 6 is a schematic diagram of the first orifice plate 30 and the second orifice plate 40 being in a wind-shielding position and in a connected state; Figure 7 yes Figure 6 A magnified view of point B; Figure 8 is a schematic diagram of the first orifice plate 30 and the second orifice plate 40 being in a wind-shielding position and in a staggered state; Fig. 9 yes Figure 8 Enlarged view of point C; Fig.10 is a schematic diagram of the inner side view of the first orifice plate 30 and the second orifice plate 40 when they are in an assembled state; Fig.11 yes Fig.10 Schematic diagram of the decomposition.

[0064] In some embodiments, Figures 4 to 11 As shown, each driving mechanism 50 can be connected to the first orifice plate 30, that is, the first orifice plate 30 is directly driven by the driving mechanism 50, and the second orifice plate 40 is driven to move by the first orifice plate 30. The housing 10 can include an air outlet frame 15, the air outlet frame 15 is used to define the air outlet 12, and the driving mechanism 50 is installed on the air outlet frame 15.

[0065] The edge of the second orifice plate 40 is provided with a positioning portion 420. For example, for a vertical air conditioner indoor unit, the top edge of the second orifice plate 40 may be provided with a positioning portion 420. The housing 10 is provided with a first stopper 161 and a second stopper 162. The air conditioner indoor unit is configured as follows:

[0066] When the first orifice plate 30 and the second orifice plate 40 are moved to the wind shielding position in a communicating state (from Figures 5 to 7 , moves in the positive direction along the x-axis), so that the positioning portion 420 is blocked by the first stopper 161 and the second orifice plate 40 stops moving, so that the first orifice plate 30 continues to move (moves in the positive direction along the x-axis) to the staggered state (from Figures 7 to 9 ), so that the plurality of first through holes 301 and the plurality of second through holes 401 are staggered.

[0067] The first orifice plate 30 and the second orifice plate 40 move in a staggered state (from Fig. 9 When the first orifice plate 30 starts to move in the negative direction of the x-axis to the open position, the positioning portion 420 is blocked by the second stopper 162 to stop the second orifice plate 40 from moving, so that the first orifice plate 30 continues to move (moves in the negative direction of the x-axis) to the connected state ( Figure 5 ).

[0068] It should be noted that the positive / negative direction of the x-axis here represents the moving direction of the first orifice plate 30 and the second orifice plate 40. The positive direction of the x-axis represents the closing direction of the orifice plate, and the negative direction of the x-axis represents the opening direction of the orifice plate. Therefore, the x-axis direction is not necessarily a straight line direction, but can also be an arc direction or other curved direction.

[0069] The embodiment of the present invention does not need to set up a separate driving mechanism for each orifice plate. It only needs to drive the first orifice plate 30 to drive the second orifice plate 40 to move, and the timely stopping of the second orifice plate 40 by two stop parts can realize the switching of the staggered / connected state of the two orifice plates. The structure is very clever and the driving mechanism 50 is simplified.

[0070] In some embodiments, Fig.10 and Fig.11 As shown, the two ends of the first orifice plate 30 (for a vertical air conditioner indoor unit, preferably the upper and lower ends of the first orifice plate 30) respectively have first flanges 32 bent toward the inner side of the casing 10. The two ends of the second orifice plate 40 (for a vertical air conditioner indoor unit, preferably the upper and lower ends of the second orifice plate 40) respectively have second flanges 42 bent toward the inner side of the casing 10. The second orifice plate 40 is attached to the inner side of the first orifice plate 30, and the two second flanges 42 are attached to the inner sides of the two first flanges 32, so that the first orifice plate 30 can move with the second orifice plate 40. Of course, the first flange 32 and the second flange 42 cannot be too tightly attached to each other to avoid the two being unable to move relative to each other.

[0071] The positioning portion 420 is disposed on the second flange 42 and extends through the first clearance hole 325 formed in the first flange 32. At least one mounting portion 33 extends from the inner side of the first orifice plate 30, and each mounting portion 33 extends through the second clearance hole 43 formed in the second orifice plate 40 to connect with a driving mechanism 50.

[0072] Further, when the first orifice plate 30 and the second orifice plate 40 are in the connected state and the staggered state, the positioning portion 420 is respectively abutted against the opposite ends of the first clearance hole 325. That is, the first clearance hole 325 is used to limit the movement range of the positioning portion 420.

[0073] In some embodiments, Fig.10 and Fig.11As shown, each driving mechanism 50 can be a gear rack mechanism, which includes a motor 51, a gear 52 and a rack 53. The motor 51 is fixedly mounted on the housing 10, and can be specifically mounted on the air outlet frame 15 of the housing 10. The gear 52 is fixed to the rotating shaft of the motor 51. The rack 53 is slidably mounted on the air outlet frame 15 and meshes with the gear 52. The rack 53 is connected to the first orifice plate 30 through a connecting rod 54, and the two ends of the connecting rod 54 are respectively hinged to the rack 53 and the first orifice plate 30. When the motor 51 drives the gear 52 to rotate, the gear 52 drives the rack 53 to move, and the rack 53 drives the first orifice plate 30 to move through the connecting rod 54.

[0074] Fig.12 Schematic diagram of the matching structure of the first orifice plate 30, the top of the second orifice plate 40 and the slide rail 16; Fig.13 It is a schematic diagram of the structure of the first orifice plate 30 , the top of the second orifice plate 40 and the bottom of the slide rail 16 .

[0075] like Figures 11 to 13 As shown, the first slide post 321 and the second slide post 322 may be provided at the end of the first orifice plate 30, and the housing 10 may be provided with a first slide groove 163 and a second slide groove 164. When the driving mechanism 50 drives the first orifice plate 30 to move, the first slide post 321 slides in the first slide groove 163, and the second slide post 322 slides in the second slide groove 164. Specifically, a slide rail 16 may be fixedly provided in the housing 10, and the first slide groove 163, the second slide groove 164, the first stopper 161 and the second stopper 162 are all formed on the slide rail 16.

[0076] Further, when the first orifice plate 30 and the second orifice plate 40 are in the open position and in the connected state, the first slide post 321 and the second slide post 322 respectively abut against one end (end A and end D) of the first slide slot 163 and the second slide slot 164, and when the first orifice plate 30 and the second orifice plate 40 are in the windproof position and in the staggered state, the first slide post 321 and the second slide post 322 respectively abut against the other end (end B and end C) of the first slide slot 163 and the second slide slot 164. In this way, the movement of the first orifice plate 30 is guided and limited by the first slide slot 163 and the second slide slot 164.

[0077] 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 that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in 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 recognized as covering all these other variations or modifications.
