Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, and specifically provides an air conditioner indoor unit and an air conditioner. Background Art

[0002] An air conditioner is a cooling and heating device, which generally includes an indoor unit and an outdoor unit. An air conditioner generally uses the indoor unit for cooling and heating. Specifically, when the air conditioner is running in the cold winter, the indoor unit of the air conditioner heats up the room; when the air conditioner is running in the hot summer, the indoor unit of the air conditioner cools down the room. Therefore, air conditioners can provide users with a comfortable living and working environment. However, when the cold or hot air blown by the indoor unit of the air conditioner blows directly to the user, it will not only cause discomfort to the user, but also easily cause the user to have symptoms such as colds, fevers, and headaches.

[0003] Existing air conditioners generally prevent cold or hot air from blowing directly at the user by adjusting the angle of the air guide plate of the indoor unit of the air conditioner, or by allowing the user to purchase and install a multi-hole windshield. The former generally blows the cold or hot air to one area of ​​the room, which has poor uniformity in cooling and heating the room. The latter requires the user to manually adjust the windshield, which has a poor user experience.

[0004] The utility model aims to provide a new direct blowing prevention solution. Utility Model Content

[0005] One purpose of the utility model is to provide a new air-conditioning indoor unit and an air conditioner to solve the problem that the wind blown out by the air-conditioning indoor unit directly blows on the user.

[0006] Another object of the utility model is to solve the problem of poor temperature uniformity when the indoor unit of the air conditioner cools or heats the room.

[0007] To achieve the above-mentioned object, the utility model provides an air conditioner indoor unit in a first aspect, comprising:

[0008] A housing having a return air vent and an air supply vent;

[0009] At least two wind shield components are sequentially arranged at the air supply outlet along the air outlet direction of the air supply outlet, and each of the wind shield components includes a plurality of first wind shield strips distributed at intervals, so that the air in the casing is blown out from the gap between two adjacent first wind shield strips; at least a part of the at least two wind shield components is configured to be movable in a direction perpendicular to the first wind shield strips, so that the first wind shield strips of each wind shield component are aligned or misaligned.

[0010] Optionally, the first wind shield strip is perpendicular to the left-right direction or the up-down direction of the casing.

[0011] Optionally, each of the windshield components further comprises at least one fixed beam, and the fixed beam is fixedly connected to or integrally formed with all of the first windshield strips.

[0012] Optionally, the cross-section of the first wind shield strip is rectangular, diamond-shaped, circular or elliptical.

[0013] Optionally, the air-conditioning indoor unit further comprises a first driving device, which is drivingly connected to the wind shield component to drive the wind shield component to move in a direction perpendicular to the first wind shield strip, thereby aligning or misaligning the first wind shield strips of each wind shield component.

[0014] Optionally, each of the wind shield components further includes a plurality of second wind shield strips distributed at intervals, and the second wind shield strips are perpendicular to the first wind shield strips; at least a portion of the at least two wind shield components are also configured to be able to move in a direction perpendicular to the second wind shield strips so that the second wind shield strips of each of the wind shield components are aligned or misaligned.

[0015] Optionally, the cross-section of the second wind shield strip is rectangular, diamond-shaped, circular or elliptical.

[0016] Optionally, the air conditioner indoor unit also includes a second driving device, which is drivingly connected to the wind shield component to drive the wind shield component to move in a direction perpendicular to the second wind shield strip, so that the second wind shield strips of each wind shield component are aligned or misaligned.

[0017] Optionally, the air-conditioning indoor unit is an embedded air-conditioner.

[0018] The utility model provides an air conditioner in a second aspect, comprising an air conditioner outdoor unit and an air conditioner indoor unit as described in any one of the first aspects.

[0019] Based on the foregoing description, it can be understood by those skilled in the art that, in the aforementioned technical solution of the utility model, at least two windshield components are sequentially arranged along the air outlet direction of the air outlet at the air outlet of the air-conditioning indoor unit, and each windshield component includes a plurality of first windshield strips distributed at intervals, so that the air in the casing can be blown out from the gap between two adjacent first windshield strips. At least a part of the windshield components of the at least two windshield components is configured to be able to move in a direction perpendicular to the first windshield strips, so that the first windshield strips of each windshield component are aligned or misaligned. When the first windshield strips of each windshield component are aligned, the air-conditioning indoor unit can blow air forward, left, right, upward or downward, with a large air volume, and can quickly heat up or cool down the room. When the first windshield strips of each windshield component are misaligned, at least two windshield components jointly block the airflow, so that the airflow cannot continue to blow out in the same direction, but is broken up to form an airflow with a lower flow rate. Therefore, the air-conditioning indoor unit of the utility model can prevent cold wind and hot wind from blowing directly on the user, thereby achieving a windless blowing effect.

[0020] Those skilled in the art can also understand that, since the at least two wind shielding components of the air conditioner indoor unit of the utility model can break up the airflow, the airflow is no longer blown to a certain area of ​​the room at a faster flow rate, but is evenly diffused to the entire room at a smaller flow rate, thereby improving the temperature uniformity of the air conditioner indoor unit when cooling or heating the room.

[0021] Furthermore, by configuring a first driving device connected to the wind shield component for the air conditioner indoor unit, the wind shield component can move in a direction perpendicular to the first wind shield strip when driven by the first driving device, thereby aligning or misaligning the first wind shield strips of each wind shield component.

[0022] Furthermore, by making each wind shield component also include a plurality of second wind shield strips distributed at intervals, and making the second wind shield strips perpendicular to the first wind shield strips, and by configuring at least a part of the at least two wind shield components to be movable in a direction perpendicular to the second wind shield strips, so that the second wind shield strips of each wind shield component are aligned or misaligned; the air-conditioning indoor unit of the utility model can direct the blown wind to the front, left, right, top or bottom through at least two wind shield components.

[0037] It should be understood by those skilled in the art that the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention, and the embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0038] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] Furthermore, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. For example, the terms "install", "connect", "connect" and "fix", unless otherwise specifically described, can specifically be any feasible connection form such as bolt connection, screw connection, welding, plug-in, riveting, melting, and clamping.

[0040] In addition, it should be noted that in the description of the present utility model, the terms "cold" and "heat" are two descriptions of the same physical state. That is, the higher the "cold" of a certain target object (such as an evaporator, air, condenser, etc.), the lower the "heat" it has, and the lower the "cold" it has, the higher the "heat" it has. A certain target object will release "heat" while absorbing "cold", and will absorb "heat" while releasing "cold". A certain target object stores "cold" or "heat" in order to keep the current temperature of the target object. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, that is, a certain target object (such as an evaporator) will absorb heat while cooling.

[0041] like Figure 1 As shown, in some embodiments of the present invention, the air-conditioning indoor unit 100 includes a casing 110 and at least two wind shielding components 120 .

[0042] The housing 110 has a return air port 1101 and an air supply port 1102, so that the outside air enters the housing 110 from the return air port 1101, and is cooled or heated by the air conditioner indoor unit 100; and the air in the air conditioner indoor unit 100 is blown to the outside from the air supply port 1102.

[0043] At least two windshield members 120 are sequentially arranged at the air outlet 1102 along the air outlet direction of the air outlet 1102. Each windshield member 120 includes a plurality of first windshield strips 121 spaced apart from each other, so that the air in the housing 110 is blown out from the gap between two adjacent first windshield strips 121.

[0044] Further, at least a portion of the at least two wind shielding members 120 are configured to be movable in a direction perpendicular to the first wind shielding strips 121 , so that the first wind shielding strips 121 of each wind shielding member 120 are aligned or misaligned.

[0045] like Figure 2 As shown, when the air conditioner indoor unit 100 blows air forward, each wind shielding member 120 is moved to align the respective first wind shielding strips 121 in the front-to-back direction, thereby forming a wind shielding strip 121 facing the front. Figure 2 The air guide channel 101 extends in the front-to-back direction. Then the air is blown forward along the air guide channel 101 (such as Figure 2 (indicated by the arrow in the middle).

[0046] like Figure 3 As shown, when the air conditioner indoor unit 100 blows air to the left, each wind shielding member 120 is moved to the front-to-back direction so that each first wind shielding strip 121 is sequentially displaced, thereby forming a wind shielding strip 121 facing the left side. Figure 2 The air guide channel 101 extends to the left front of the middle. Then the air is blown out to the left front along the air guide channel 101 (such as Figure 2 (indicated by the arrow in the middle).

[0047] Accordingly, when the air conditioner indoor unit 100 blows air to the right, each wind shielding member 120 is moved to the front-rear direction so that each first wind shielding strip 121 is sequentially displaced, thereby forming a wind shielding member 120 facing the right side. Figure 2 The wind guide channel 101 extending from the middle right front (with Figure 2 The state and position of the first windshield strip 121 shown in the figure are symmetrical). Then, the air is blown out to the right front along the wind guide channel 101 (same as Figure 2 The arrows in the middle are symmetrical.

[0048] like Figure 4 As shown, when the air conditioner indoor unit 100 is protected from direct blowing, each wind shielding member 120 is moved to make each first wind shielding strip 121 reciprocate in the front-rear direction, thereby forming Figure 4The air is then dispersed under the action of the air guide structure to form an airflow with a lower flow rate, preventing cold wind and hot wind from blowing directly on the user, thereby achieving a windless blowing effect.

[0049] Based on the above description, in some embodiments of the utility model, at least two windshield members 120 are arranged in sequence along the air outlet direction of the air outlet 1102 at the air outlet 1102 of the air conditioner indoor unit 100, and each windshield member 120 includes a plurality of first windshield strips 121 distributed at intervals, so that the air in the housing 110 can be blown out from the gap between two adjacent first windshield strips 121. At least a part of the at least two windshield members 120 is configured to be movable in a direction perpendicular to the first windshield strips 121, so that the first windshield strips 121 of each windshield member 120 are aligned or misaligned. When the first windshield strips 121 of each windshield member 120 are aligned, the air conditioner indoor unit 100 can blow air forward, left, right, upward or downward, with a large air volume, and can quickly heat up or cool down the room. When the first wind shielding strips 121 of each wind shielding member 120 are misaligned, at least two wind shielding members 120 block the airflow together, so that the airflow cannot continue to blow out in the same direction, but is dispersed to form an airflow with a lower flow rate. Therefore, the air conditioner indoor unit 100 of the utility model can prevent cold air and hot air from blowing directly to the user, thereby achieving a windless blowing effect.

[0050] like Figure 5 As shown, in some embodiments of the present invention, the air-conditioning indoor unit 100 further includes a heat exchanger 130 and a fan 140 .

[0051] The heat exchanger 130 is disposed in the casing 110 and is used to heat or cool the air in the casing 110 .

[0052] Furthermore, when the air conditioner indoor unit 100 is cooling, the heat exchanger 130 is used as an evaporator to cool the air in the casing 110 ; when the air conditioner indoor unit 100 is heating, the heat exchanger 130 is used as a condenser to heat the air in the casing 110 .

[0053] The fan 140 is disposed in the housing 110 and is used to drive air to flow from the return air port 1101 to the supply air port 1102 via the heat exchanger 130 .

[0054] Continue reading Figure 5 In some embodiments of the present invention, the return air outlet 1101 and the supply air outlet 1102 are both arranged on the front side panel of the housing 110 .

[0055] Those skilled in the art can understand that by setting both the return air vent 1101 and the supply air vent 1102 on the front side plate of the housing 110, the air conditioner indoor unit 100 can be installed in a small space, without having to reserve more top return air space like a traditional wall-mounted air conditioner. Therefore, the air conditioner indoor unit 100 of the utility model has more applicable scenarios and better return air effect.

[0056] Continue reading Figure 5 In some embodiments of the present invention, the air conditioner indoor unit 100 may further include a partition 150. The partition 150 is disposed in the housing 110 and extends from the return air port 1101 to the heat exchanger 130, so that the air on the top side of the partition 150 flows to the portion of the heat exchanger 130 located on the top side of the fan 140. In other words, the partition 150 divides the housing 110 into two return air passages, one of which leads to the front of the heat exchanger 130 and the other leads to the rear of the heat exchanger 130.

[0057] Those skilled in the art will appreciate that by extending the partition 150 from the return air port 1101 toward the heat exchanger 130, the air on the top side of the partition 150 flows toward the portion of the heat exchanger 130 located on the top side of the fan 140, and thus air flows through each portion of the heat exchanger 130, thereby ensuring the working efficiency of the heat exchanger 130. In addition, ice formation at the rear of the heat exchanger 130 due to insufficient air volume is avoided.

[0058] Furthermore, the partition 150 may be fixedly connected to the housing 110 or may be integrally formed therewith.

[0059] In example 1, the partition plate 150 is integrally formed with the front side plate of the housing 110 .

[0060] Example 2: A plug-in structure is provided on the partition 150, and a plug-in matching structure is provided on the front side plate of the housing 110. The partition 150 is plugged together with the front side plate of the housing 110 through the plug-in structure and the plug-in matching structure.

[0061] Example three: A vertical mounting plate is provided on the partition 150, a through hole is provided on the mounting plate, and a threaded hole is provided on the front side plate of the casing 110. The screws pass through the through holes and are tightened together with the threaded holes, thereby fixing the partition 150 to the front side plate of the casing 110.

[0062] like Figure 1 and Figure 6 As shown, in some embodiments of the present invention, the first wind shielding strip 121 is perpendicular to the up-down direction of the housing 110 .

[0063] In addition, those skilled in the art may also make the first wind shielding strip 121 perpendicular to the left-right direction of the housing 110 as needed.

[0064] Furthermore, each wind shielding member 120 further includes at least one fixed beam 122 , and the fixed beam 122 is fixedly connected to or integrally formed with all the first wind shielding strips 121 .

[0065] like Figure 1 and Figure 6 As shown, each wind shielding member 120 is provided with a fixing beam 122 at both ends of the first wind shielding strip 121 in the length direction, so as to ensure the structural strength of the wind shielding member 120 .

[0066] Furthermore, in some embodiments of the present invention, the cross section of the first windshield strip 121 is rectangular, diamond-shaped, circular or elliptical. Those skilled in the art can select the first windshield strip 121 of any shape according to actual needs.

[0067] like Figure 6 As shown, in some embodiments of the present invention, the air conditioner indoor unit 100 may include four wind shielding members 120. In addition, those skilled in the art may also make the air conditioner indoor unit 100 include any other number of wind shielding members 120, such as three, five, eight, etc., as required.

[0068] Furthermore, in some embodiments of the present invention, the two wind shielding components 120 may be in sliding contact or may be in clearance fit.

[0069] Furthermore, there may be a spacing between the first wind shielding strips 121 of two adjacent wind shielding members 120 to ensure that the air conditioner indoor unit 100 can be Figure 4 The blown wind is dispersed as shown.

[0070] like Figure 7 As shown, in some embodiments of the present invention, the air conditioner indoor unit 100 may further include a first driving device 161. The first driving device 161 is drivingly connected to the windshield member 120 to drive the windshield member 120 to move in a direction perpendicular to the first windshield strips 121, so that the first windshield strips 121 of each windshield member 120 are aligned or misaligned.

[0071] Furthermore, the air-conditioning indoor unit 100 may configure a first driving device 161 for each first wind shielding strip 121 .

[0072] The first driving device 161 may be a motor or an electric push rod.

[0073] For example, in some embodiments of the present invention, each windshield member 120 is slidably connected to the housing 110, and a rack is provided at one end of each windshield member 120 in the left and right directions. Each windshield member 120 is respectively provided with a first driving device 161. The first driving device 161 is a motor, and is fixedly connected to a gear, which meshes with the rack. The motor drives the windshield member 120 to move left and right by forward and reverse rotation, so that the first windshield strips 121 of each windshield member 120 are aligned or misaligned.

[0074] The sliding connection between the wind shielding member 120 and the housing 110 may specifically be that a plurality of slide grooves extending in the left-right direction are provided on the housing 110, and the fixed beams 122 of the wind shielding member 120 may be slidably embedded in the slide grooves.

[0075] like Figure 8 As shown, in some embodiments of the present invention, the air-conditioning indoor unit 100 may be a built-in air-conditioning unit, which may be embedded in the cabinet 001 or in any other feasible space.

[0076] like Fig. 9 As shown, in other embodiments of the present invention, each windshield member 120 may further include a plurality of second windshield strips 123 that are spaced apart. The second windshield strips 123 are perpendicular to the first windshield strips 121. That is, the second windshield strips 123 are perpendicular to the front-to-back direction of the air-conditioning indoor unit 100; that is, the second windshield strips 123 extend along the left-right direction of the air-conditioning indoor unit 100.

[0077] Furthermore, the second wind shield strip 123 and the first wind shield strip 121 can be Fig. 9 As shown, they are independent, connected front to back or spaced from each other; the second windshield strip 123 and the first windshield strip 121 can also be as Fig.10 As shown, they are made in one piece.

[0078] The cross section of the second windshield strip 123 is rectangular, rhombus, circular or elliptical. Those skilled in the art can select the second windshield strip 123 of any shape according to actual needs.

[0079] Furthermore, at least a portion of the at least two wind shielding members 120 are also configured to be movable in a direction perpendicular to the second wind shielding strips 123 , so that the second wind shielding strips 123 of each wind shielding member 120 are aligned or misaligned.

[0080] Specifically, Fig.11As shown, in some embodiments of the present invention, the air-conditioning indoor unit 100 may further include a second driving device 162, which is drivingly connected to the wind shield component 120 to drive the wind shield component 120 to move in a direction perpendicular to the second wind shield strip 123, so that the second wind shield strips 123 of each wind shield component 120 are aligned or misaligned.

[0081] Furthermore, the air-conditioning indoor unit 100 may configure a second driving device 162 for each second wind shielding strip 123 .

[0082] The second driving device 162 may be a motor or an electric push rod.

[0083] For example, Fig.11 As shown, the air conditioner indoor unit 100 further includes a plurality of fixing frames 170, which are slidably connected to the casing 110 in a left-right direction perpendicular to the casing 110. Specifically, the casing 110 is provided with a plurality of slide grooves extending perpendicular to the left-right direction, and the fixing frames 170 are slidably embedded in the slide grooves.

[0084] Furthermore, a windshield member 120 is slidably connected to each fixing frame 170. Specifically, a slide groove extending in the left-right direction is provided on the fixing frame 170, and the fixing beam 122 of the windshield member 120 is embedded in the slide groove.

[0085] Furthermore, each fixed frame 170 corresponds to a second driving device 162. The second driving device 162 is a motor and is fixedly connected to a gear. A rack meshing with the gear is provided on the fixed frame 170, and the motor drives the windshield member 120 to move in a direction perpendicular to the left and right directions by forward and reverse rotation, so that the second windshield strips 123 of each windshield member 120 are aligned or misaligned, so that the air conditioner indoor unit 100 blows air upward or downward.

[0086] Furthermore, a first driving device 161 is respectively disposed between the fixing frame 170 and the corresponding windshield member 120. Please refer to the above description for the first driving device 161 and its driving of the windshield member 120.

[0087] In addition, the utility model also provides an air conditioner 002.

[0088] like Fig.12 As shown, the air conditioner 002 includes the air conditioner indoor unit 100 and the air conditioner outdoor unit 200 described in any of the above embodiments.

[0089] When the air conditioner 002 is cooling, the air conditioner outdoor unit 200 releases heat, and the air conditioner indoor unit 100 absorbs heat to cool the room.

[0090] When the air conditioner 002 is heating, the air conditioner outdoor unit 200 absorbs heat, and the air conditioner indoor unit 100 releases heat to heat the room.

[0091] The air conditioner 002 generally needs to use its refrigeration system to complete cooling or heating.

[0092] The refrigeration system includes a compressor, a condenser, a pressure reducing component (an expansion valve or a capillary tube) and an evaporator which are connected end to end in sequence.

[0093] Among them, the compressor and the pressure reducing member are generally provided in the air conditioner outdoor unit 200 .

[0094] Furthermore, a heat exchanger 130 is disposed in the air-conditioning outdoor unit 200 and the air-conditioning indoor unit 100 , respectively.

[0095] When the air conditioner 002 is working, the refrigerant in the refrigeration system circulates along the following path: compressor→condenser→pressure reducing component→evaporator→compressor.

[0096] Specifically, when the refrigerant flows through the compressor, it is compressed by the compressor into a high temperature and high pressure state (liquid or gas-liquid mixed state). When the refrigerant flows through the condenser, the condenser dissipates heat and the temperature is reduced to a low temperature and high pressure state (liquid or gas-liquid mixed state). When the refrigerant flows through the pressure reducing component, it is throttled and reduced to a low temperature and low pressure state (liquid or gas-liquid mixed state) by the pressure reducing component. When the refrigerant flows through the evaporator, it absorbs heat from the external environment through the evaporator and heats up to a high temperature and low pressure state (gaseous state).

[0097] Among them, the aforementioned states of the refrigerant in the compressor, condenser, pressure reducing component, and evaporator, that is, the high temperature, low temperature, high pressure, and low pressure of the refrigerant, are the states of the refrigerant after entering the corresponding components or flowing out of the corresponding components compared to the states before it flows into the corresponding components.

[0098] When the air conditioner 002 is heating, the heat exchanger 130 in the air conditioner outdoor unit 200 is used as an evaporator, and the heat exchanger 130 in the air conditioner indoor unit 100 is used as a condenser.

[0099] When the air conditioner 002 is cooling, the heat exchanger 130 in the air conditioner outdoor unit 200 is used as a condenser, and the heat exchanger 130 in the air conditioner indoor unit 100 is used as an evaporator.

[0100] It should be noted that the present invention only describes the main components of the refrigeration system and the general refrigerant flow path. In actual product applications, the refrigeration system may also have at least one series and / or parallel branch.

[0101] So far, the technical solution of the utility model has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the utility model is not limited to these specific embodiments. Without departing from the technical principle of the utility model, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principle of the utility model will fall within the protection scope of the utility model.

[0102] Finally, it should be noted that the term "communication" means fluid communication, so as to allow fluid (such as air, liquid) to flow between two connected objects. And the "communication" can be to allow the fluid to flow between the two connected objects without leakage, or to allow the fluid to flow between the two connected objects with a little leakage.
