Air conditioner indoor unit and air conditioner

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application number 202310768595.4, filed with the State Intellectual Property Office of China on June 27, 2023, entitled “Air Conditioning Indoor Unit and Air Conditioner”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the technical field of air-conditioning equipment, and specifically relates to an air-conditioning indoor unit and an air conditioner. Background Art

[0004] When installing the indoor unit of an air conditioning unit, the relative positions of air duct openings vary from customer to customer, requiring the product to accommodate various air inlet and outlet configurations, such as left-in-right-out, right-in-left-out, bottom-in-top-out, and top-in-bottom-out. This results in the indoor unit being installed at various angles during on-site installation. When installing the indoor unit at different angles, the evaporator and water collection box inside the unit must be rotated to ensure the water collection box is always positioned below the evaporator and receives water.

[0005] To more accurately monitor the indoor unit's operating environment, a temperature sensor is installed at the evaporator's air inlet. However, when the evaporator rotates, the positions of its air inlet and air outlet change. To detect the temperature at the rotated air inlet, the temperature sensor typically needs to be removed and reinstalled at the rotated air inlet, complicating the installation process.

[0006] Summary of the Invention

[0007] The purpose of this application is to at least solve the problem of needing to reassemble the temperature detection component after the evaporator is rotated and installed. This purpose is achieved by the following means:

[0008] A first aspect of the present application provides an air-conditioning indoor unit, comprising:

[0009] A box body, the box body comprising an air inlet and an air outlet, and the interior of the box body is further provided with a heat exchange air duct connecting the air inlet and the air outlet;

[0011] A temperature detecting element is provided at the vent and is used to detect the air flow temperature at the vent.

[0012] When the first opening of the air guide cavity is set toward the air inlet, the air outside the box can enter the guide cavity through the air inlet and the first opening in sequence, and flow out to the outside of the guide cavity through the air vent. In this process, the temperature detection member provided at the air vent can detect the air flow passing through the air vent, that is, the air flow that has not exchanged heat with the indoor heat exchanger, thereby detecting the air intake temperature of the air conditioner indoor unit; when it is necessary to rotate the angle of the indoor heat exchanger according to the installation position of the air inlet, such as turning the indoor heat exchanger upward, the air inlet can be turned downward. When the internal heat exchanger rotates 180°, the first opening of the guide cavity is set toward the air outlet, and the airflow outside the box can enter the guide cavity through the air inlet and the vent in turn. During this process, the temperature detection component arranged at the vent can also detect the airflow passing through the vent, that is, the airflow that has not exchanged heat with the indoor heat exchanger, so as to detect the intake air temperature of the air-conditioning indoor unit.

[0042] Central air conditioning includes air conditioning indoor unit and air conditioning indoor unit. Air conditioning indoor unit is usually installed outdoors, and air conditioning indoor unit is usually installed indoors. Air conditioning indoor unit and air conditioning indoor unit work together to realize the cooling, heating, dehumidification and air purification functions of the air conditioner to achieve comfortable air quality.

[0043] Central air conditioning typically has one indoor unit, but the number can be multiple. Each unit is equipped with one or more air outlets to discharge cooled, heated, dehumidified, or purified air into the room. The indoor unit is typically equipped with an indoor heat exchanger, and the outdoor unit is typically equipped with an outdoor heat exchanger. The indoor and outdoor heat exchangers are typically connected by a refrigerant pipe, allowing refrigerant to circulate between the indoor and outdoor heat exchangers.

[0044] During the cooling process of the central air conditioner, the indoor heat exchanger is the evaporator, and the refrigerant in the evaporator absorbs heat from liquid to gas. In the process of refrigerant evaporation and heat absorption, the evaporator exchanges heat with the air flowing through the evaporator, taking away the heat in the air in the air-conditioning indoor unit, so that the air discharged from the air-conditioning indoor unit is the air that has released heat and cooled down, and the air-conditioning indoor unit blows cold air. At the same time, the outdoor heat exchanger is the condenser, and the refrigerant in the condenser changes from gas to liquid. In the process of refrigerant condensation and heat release, the condenser exchanges heat with the air in the air-conditioning indoor unit flowing through the condenser, so that the air in the air-conditioning indoor unit brings the heat of the condenser to the outside of the air-conditioning indoor unit, realizing the cooling process.

[0045] During the heating process of the central air conditioner, the outdoor heat exchanger is the evaporator, and the refrigerant in the evaporator absorbs heat from liquid to gas. In the process of refrigerant evaporation and heat absorption, the evaporator exchanges heat with the air flowing through the evaporator, and replaces the heat carried by the air in the air conditioner indoor unit with the refrigerant in the evaporator. At the same time, the indoor heat exchanger is the condenser, and the refrigerant in the condenser changes from gas to liquid. In the process of refrigerant condensation and heat release, the condenser exchanges heat with the air in the air conditioner indoor unit flowing through the condenser, so that the air in the air conditioner indoor unit takes away the heat carried by the condenser and is discharged from the air conditioner indoor unit to the room outside the air conditioner indoor unit, so that the indoor unit blows hot air, thus realizing the heating process.

[0046] Because the relative positions of air duct openings in different users' rooms are not uniform, the product needs to be able to achieve multiple air inlet and outlet installation methods, such as left-in-right-out, right-in-left-out, bottom-in-top-out, top-in-bottom-out, etc. This results in the air conditioner indoor unit being installed at various angles during on-site installation. When installing the air conditioner indoor unit at different angles, the angle of the evaporator and water collection box inside the box must be rotated so that the water collection box is always below the evaporator and can collect water.

[0047] To more accurately monitor the indoor unit's operating environment, a temperature sensor is installed at the evaporator's air inlet. However, when the evaporator rotates, the positions of its air inlet and air outlet change. To detect the temperature at the rotated air inlet, the temperature sensor typically needs to be removed and reinstalled at the rotated air inlet, complicating the installation process.

[0048] In order to solve the problem of needing to reassemble the temperature detection component after the evaporator is rotated and installed, the present application proposes an air-conditioning indoor unit and an air conditioner having the same. By fixing the temperature detection component on the air-conditioning indoor unit assembly and enabling the temperature detection component to always detect the temperature of the air inlet of the air-conditioning indoor unit, there is no need to disassemble and reinstall the temperature detection component during the process of rotating the angle of the indoor heat exchanger assembly, thereby reducing the complexity of the installation process of the air-conditioning indoor unit.

[0049] With reference to Figures 1 to 7 of the present application, Figures 1 to 4 are schematic diagrams of the structure of the air-conditioning indoor unit 1 when air enters from the bottom and air exits from the top. In this case, the water receiving box 80 is located below the indoor heat exchanger 21. Figures 5 to 7 are schematic diagrams of the structure of the air-conditioning indoor unit 1 when air enters from the top and air exits from the bottom. Since the overall structure of the air-conditioning indoor unit 1 has been rotated 180°, in order for the water receiving box 80 to smoothly undertake the task of receiving water, the positions of the water receiving box 80 and the indoor heat exchanger 21 need to be adjusted. The indoor heat exchanger 21 needs to be relocated above the water receiving box 80, and the angle of the indoor heat exchanger 21 needs to be flipped 180° in the vertical direction.

[0050] In combination with Figures 1 to 7, in some embodiments of the present application, the air-conditioning indoor unit 1 includes a box body 10, an indoor heat exchanger assembly 20 and a temperature detection component 30. The box body 10 includes an air inlet 11 and an air outlet 12. The interior of the box body 10 is also provided with a heat exchange air duct connecting the air inlet 11 and the air outlet 12. The indoor heat exchanger assembly 20 is arranged in the heat exchange air duct. The indoor heat exchanger assembly 20 includes an indoor heat exchanger 21 and a baffle 22. The indoor heat exchanger 21 is connected to the baffle 22 and together forms a guide cavity 24. One end of the guide cavity 24 is provided with a first opening 241, and the first opening 241 is arranged toward the air inlet 11 or the air outlet 12. The end of the baffle 22 away from the first opening 241 is provided with a vent connected to the guide cavity 24. The temperature detection component 30 is provided at the vent and is used to detect the air flow temperature at the vent.

[0051] Specifically, the housing 10 is used to constitute the overall appearance structure of the air-conditioning indoor unit 1, and an installation cavity for installing various accessories is provided inside the housing 10. An air inlet 11 is provided at one end of the housing 10, and an air outlet 12 is provided at the other end. A heat exchange duct is formed inside the housing 10 between the air inlet 11 and the air outlet 12. The indoor heat exchanger assembly 20 is arranged in the heat exchange duct, and the indoor heat exchanger 21 in the indoor heat exchanger assembly 20 can exchange heat with the air flow entering the heat exchange duct. The air flow after heat exchange can be discharged to the outside of the housing 10 through the air outlet 12 and discharged into the indoor environment, thereby adjusting the indoor ambient temperature. Among them, the direction indicated by the black straight arrow in the accompanying figure is the direction of air flow in the heat exchange duct.

[0052] The indoor heat exchanger assembly 20 also includes a baffle 22, and the indoor heat exchanger 21 is connected to the baffle 22 and together encloses a flow guide cavity 24. The airflow outside the box 10 can flow into the flow guide cavity 24 through the air inlet 11, and exchange heat with the indoor heat exchanger 21 in the process of flowing out of the flow guide cavity 24, thereby changing the temperature of the airflow itself. By providing a vent on the baffle 22 and arranging a temperature detection component 30 at the vent, the airflow can contact the temperature detection component 30 in the process of flowing through the vent, thereby detecting the airflow temperature at the vent. Among them, the temperature detection component 30 can be a temperature sensor.

[0053] According to the air-conditioning indoor unit 1 of the present application, by providing a guide cavity 24 and a ventilation hole connected to the guide cavity 24, when the first opening 241 of the guide cavity 24 is set toward the air inlet 11, the airflow outside the box body 10 can enter the guide cavity 24 through the air inlet 11 and the first opening 241 in sequence, and flow out to the outside of the guide cavity 24 through the ventilation hole. In this process, the temperature detection member 30 provided at the ventilation hole can detect the airflow flowing through the ventilation hole, that is, the airflow that has not exchanged heat with the indoor heat exchanger 21, so as to detect the intake air temperature of the air-conditioning indoor unit 1; when it is necessary to rotate the angle of the indoor heat exchanger 21 according to the installation position of the air inlet 11 For example, when the indoor heat exchanger 21 is rotated 180 degrees, the first opening 241 of the guide cavity 24 is set toward the air outlet 12, and the airflow outside the box body 10 can enter the guide cavity 24 through the air inlet 11 and the vent in sequence. During this process, the temperature detection component 30 provided at the vent can also detect the airflow passing through the vent, that is, the airflow that has not exchanged heat with the indoor heat exchanger 21, so as to detect the intake air temperature of the air-conditioning indoor unit 1. In the process of rotating the angle of the indoor heat exchanger 21, the temperature detection component 30 is always fixed at the vent of the baffle 22, and there is no need to disassemble and reinstall it, which reduces the complexity of the installation process of the air-conditioning indoor unit 1.

[0054] As shown in Figures 2 and 3, in some embodiments of the present application, the indoor heat exchanger 21 includes a first heat exchange portion 211 and a second heat exchange portion 212 arranged at a first angle a, and the first heat exchange portion 211 and the second heat exchange portion 212 are respectively connected to the baffle 22 on the same side edges for forming the first angle a, and the value range of the first angle a is 0°<a<180°.

[0055] Specifically, the first heat exchange portion 211 and the second heat exchange portion 212 are arranged in a generally V-shaped structure, and a baffle 22 is provided at the opening on at least one side of the V-shaped structure to prevent airflow from flowing into or out of the guide cavity 24 through the side openings of the V-shaped structure. In some embodiments of the present application, baffles 22 may be provided at the openings on both sides of the V-shaped structure to prevent airflow from flowing into or out of the guide cavity 24 through the openings on both sides of the V-shaped structure.

[0056] In combination with Figures 2 and 7, in some embodiments of the present application, the air-conditioning indoor unit 1 further includes a sensor bracket 40, which is arranged at the vent. An installation cavity is formed inside the sensor bracket 40, and the temperature detection component 30 is arranged in the installation cavity. The outside and inside of the guide cavity 24 are respectively connected to the installation cavity.

[0057] Specifically, an installation cavity for installing the temperature detection component 30 is formed inside the sensor bracket 40. By placing the temperature detection component 30 in the installation cavity and connecting the sensor bracket 40 to the baffle 22 and then placing it at the vent, the airflow in the guide cavity 24 can flow out to the outside of the guide cavity 24 through the installation cavity, as shown in Figure 4, or the airflow outside the guide cavity 24 can flow into the guide cavity 24 through the installation cavity, as shown in Figure 7, and the airflow can contact the temperature detection component 30 during the flow in the installation cavity, thereby detecting the airflow temperature through the temperature detection component 30.

[0058] 3 to 7 , in some embodiments of the present application, the sensor bracket 40 is provided with a mounting hole 43 extending through the sensor bracket 40 along its own axis, and the mounting hole 43 forms a mounting cavity.

[0059] Specifically, mounting hole 43 is a through hole extending along the axis of sensor bracket 40. A receiving space is provided within mounting hole 43 to facilitate installation of temperature detection element 30. Furthermore, the through hole structure extending through sensor bracket 40 facilitates airflow into or out of guide cavity 24, thereby facilitating detection of airflow temperature by temperature detection element 30.

[0060] 3 to 7 , in some embodiments of the present application, a plurality of first through holes 411 are provided on the circumferential surface of the sensor bracket 40 along the axial direction, and the outside and inside of the guide cavity 24 are respectively connected to the installation cavity through the first through holes 411 .

[0061] The provision of multiple first through holes 411 facilitates airflow into or out of the mounting hole 43, thereby facilitating contact between the airflow and the temperature sensing element 30. When the sensor bracket 40 is inserted into the vent, the portion of the sensor bracket 40 with the first through holes 411 can be positioned within the flow diversion cavity 24, while the other portion of the sensor bracket 40 with the first through holes 411 can be positioned outside the flow diversion cavity 24. This allows the mounting hole 43 to communicate with the interior and exterior of the flow diversion cavity 24 via the first through holes 411 on both sides of the axial direction.

[0062] In combination with Figures 3 to 7, in some embodiments of the present application, the air-conditioning indoor unit 1 also includes a support frame 50, which is arranged outside the guide cavity 24 and connected to the baffle 22. One end of the sensor bracket 40 is inserted into the guide cavity 24 through the vent, and the other end of the sensor bracket 40 is connected to the support frame 50.

[0063] Specifically, the support frame 50 is used to securely mount the sensor bracket 40. The support frame 50 may be a bent plate-like structure, with a portion of the plate-like structure connected to the baffle 22 and another portion of the plate-like structure spaced apart from the baffle 22, thereby facilitating the secure installation of the sensor bracket 40. The end of the support frame 50, away from the first opening 241, is open, thereby facilitating airflow out of or into the guide cavity 24.

[0064] As shown in Figures 4, 7, and 8, in some embodiments of the present application, the sensor bracket 40 includes a plug-in portion 41 and a fixing portion 42, wherein the plug-in portion 41 is used to be inserted into the vent, and the plug-in portion 41 is provided with a plurality of first through holes 411 spaced apart along its own axial direction and radial direction. The fixing portion 42 is provided at one end of the axial direction of the plug-in portion 41, and the outer surface of the fixing portion 42 is provided with a positioning groove 421. Part of the structure of the support frame 50 can be inserted into the positioning groove 421, thereby fixing the sensor bracket 40 to the support frame 50. In some embodiments of the present application, the plug-in portion 41 and the fixing portion 42 are respectively cylindrical structures, so that there is no need to adjust the angle during installation, which facilitates installation. The positioning groove 421 is an annular groove, and the support frame 50 is provided with a circular mounting hole, and the diameter of the circular mounting hole is smaller than the minimum diameter of the positioning groove 421, so that the positioning groove 421 can be easily snapped into the circular mounting hole on the support frame 50.

[0065] 8 , 9 and 10 , in some embodiments of the present application, the support frame 50 may be eliminated, and the positioning groove 421 of the fixing portion 42 may be directly connected to the vent, thereby directly connecting the internal and external airflows of the guide cavity 24 through the mounting hole 43 , and also enabling the temperature of the intake airflow of the air-conditioning indoor unit 1 to be detected.

[0066] In combination with Figures 3 to 7, in some embodiments of the present application, the air-conditioning indoor unit 1 also includes an air guide cover 60, which is arranged on the outside of the support frame 50 and is connected to the baffle 22. The end of the air guide cover 60 away from the first opening 241 is provided with an air guide port 61, and the air flow in the air guide cover 60 is discharged to the outside of the air guide cover 60 through the air guide port 61.

[0067] Specifically, the air guide cover 60 is provided on the outside of the support frame 50, and is also provided on the portion of the sensor bracket 40 provided on the outside of the flow guide cavity 24, thereby reducing the influence of the heat exchange airflow of the indoor heat exchanger 21 outside the flow guide cavity 24 on the detection result of the temperature detection element 30. At the same time, in order to facilitate the flow of air into or out of the air guide cover 60, an air guide port 61 is provided at the end of the air guide cover 60 away from the first opening 241. As shown in FIG4, when the air is taken in from the bottom and out from the top of the air conditioner indoor unit 1, the air guide port 61 facilitates the outflow of the air flow in the air guide cover 60. As shown in FIG5, when the air is taken in from the top and out from the bottom of the air conditioner indoor unit 1, the air guide port 61 facilitates the flow of external air into the air guide cover 60.

[0068] In combination with Figures 2 to 7, in some embodiments of the present application, the indoor heat exchanger assembly 20 also includes a connecting plate 23, and the end of the first heat exchange part 211 away from the first opening 241 and the end of the second heat exchange part 212 away from the first opening 241 are respectively connected to the connecting plate 23, and at least one second through hole 231 is provided on the connecting plate 23, and the at least one second through hole 231 is arranged opposite to the air guide port 61 in the vertical direction.

[0069] Specifically, the connecting plate 23 is used to connect the first heat exchange portion 211 and the second heat exchange portion 212, thereby forming the first heat exchange portion 211 and the second heat exchange portion 212 into a single unit. It also serves to block airflow at the end of the indoor heat exchanger assembly 20 away from the first opening 241, preventing airflow from outflow. The connecting plate 23 may include a first plate portion and a second plate portion. The first plate portion is used to connect to the first heat exchange portion 211, and the second plate portion is used to connect to the second heat exchange portion 212. The first and second plate portions are connected to form the connecting plate 23.

[0070] The air guide cover 60 is located midway between the first heat exchange portion 211 and the second heat exchange portion 212, and a plurality of second through holes 231 are correspondingly provided in the middle of the connecting plate 23.
