Description

Technical Field

[0001] 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

[0002] For the installation of indoor units in air conditioning units, since the relative positions of air duct openings in different customers' homes are not uniform, the product needs to be able to achieve multiple air inlet and outlet installation methods, such as left in and right out, right in and left out, bottom in and top out, top in and bottom out, etc. This makes the indoor unit installed at multiple angles during on-site installation. When installing the indoor unit at different angles, it is also necessary to rotate the angles of the evaporator and the water receiving box inside the box so that the water receiving box is always below the evaporator and can receive water.

[0003] At the same time, in order to more accurately monitor the state of the indoor unit operating environment, a temperature detector is also installed at the air inlet end of the evaporator. However, when the evaporator rotates, the positions of its air inlet and air outlet change. In order to detect the temperature of the air inlet after rotation, it is usually necessary to remove the temperature detector and reinstall it at the air inlet after rotation, which increases the complexity of the installation process. Summary of the invention

[0048] Central air conditioning includes air conditioning indoor unit and air conditioning indoor unit. The air conditioning indoor unit is usually installed outdoors, and the air conditioning indoor unit is usually installed indoors. The air conditioning indoor unit and air conditioning indoor unit work together to realize the air conditioner's cooling, heating, dehumidification and air purification functions to achieve comfortable air quality.

[0049] In a central air conditioner, there is usually one indoor air conditioner, but the number of indoor air conditioners can be multiple. Each indoor air conditioner is provided with one or more air outlets to discharge the cooled, heated, dehumidified or purified air into the room through the air outlets. An indoor heat exchanger is usually provided in the indoor air conditioner, and an outdoor heat exchanger is usually provided in the indoor air conditioner. The indoor heat exchanger and the outdoor heat exchanger are usually connected through a refrigerant pipeline, so that the refrigerant can flow between the indoor heat exchanger and the outdoor heat exchanger.

[0050] 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, and takes 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 after heat release and cooling, 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.

[0051] 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 discharges it from the air conditioner indoor unit to the room outside the air conditioner indoor unit, so that the indoor unit blows hot air, thereby realizing the heating process.

[0052] Since the relative positions of the air duct openings in each user's room are not uniform, the product needs to be able to achieve multiple air inlet and outlet installation methods, such as left in and right out, right in and left out, bottom in and top out, top in and bottom out, etc. This makes the air conditioner indoor unit installed at various angles during on-site installation. When installing the air conditioner indoor unit at different angles, it is also necessary to rotate the angles of the evaporator and the water receiving box inside the box so that the water receiving box is always below the evaporator and can receive water.

[0053] At the same time, in order to more accurately monitor the state of the indoor unit operating environment, a temperature detector is also installed at the air inlet end of the evaporator. However, when the evaporator rotates, the positions of its air inlet and air outlet change. In order to detect the temperature of the air inlet after rotation, it is usually necessary to remove the temperature detector and reinstall it at the air inlet after rotation, which increases the complexity of the installation process.

[0054] In order to solve the problem that the temperature detection component needs to be reassembled after the evaporator is rotated and installed, the present application proposes an air-conditioning indoor unit and an air conditioner having the same. The temperature detection component is fixed to the air-conditioning indoor unit assembly and the temperature detection component can always detect the temperature of the air inlet of the air-conditioning indoor unit. Therefore, during the process of rotating the angle of the indoor heat exchanger assembly, there is no need to disassemble and reinstall the temperature detection component, thereby reducing the complexity of the installation process of the air-conditioning indoor unit.

[0055] Combined with this application Figures 1 to 7 As shown, Figures 1 to 4 This is a schematic diagram of the structure of the air conditioner indoor unit 1 when air enters from the bottom and exits from the top. At this time, the water receiving box 80 is arranged below the indoor heat exchanger 21. Figures 5 to 7 This is a schematic diagram of the structure of the air-conditioning indoor unit 1 when air enters from the top and 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 re-located above the water receiving box 80, and the angle of the indoor heat exchanger 21 needs to be flipped 180° in the vertical direction.

[0056] Combination Figures 1 to 7 As shown, 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, and 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 encloses a guide cavity 24, one end of the guide cavity 24 is provided with a first opening 241, 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, and the temperature detection component 30 is arranged at the vent and is used to detect the air flow temperature at the vent.

[0057] Specifically, the housing 10 is used to constitute the overall appearance structure of the indoor unit 1 of the air conditioner, 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 air 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 air duct, and the indoor heat exchanger 21 in the indoor heat exchanger assembly 20 can exchange heat with the airflow entering the heat exchange air duct. The airflow 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 environment temperature. Among them, the direction indicated by the black straight arrow in the accompanying drawing is the flow direction of the airflow in the heat exchange air duct.

[0058] The indoor heat exchanger assembly 20 also includes a baffle 22, and the indoor heat exchanger 21 is connected to the baffle 22 and is jointly arranged to form a guide cavity 24. The airflow outside the box 10 can flow into the 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 guide cavity 24, thereby changing the temperature of the airflow itself. By arranging a vent on the baffle 22 and arranging a temperature detection member 30 at the vent, the airflow can contact the temperature detection member 30 in the process of flowing through the vent, thereby detecting the airflow temperature at the vent. Among them, the temperature detection member 30 can be a temperature sensor.

[0059] 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 arranged 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°, 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. In this process, the temperature detection component 30 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 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, thereby reducing the complexity of the installation process of the air-conditioning indoor unit 1.

[0061] Specifically, the first heat exchange portion 211 and the second heat exchange portion 212 are arranged in a substantially V-shaped structure, and a baffle 22 is arranged at the opening of at least one side of the V-shaped structure to prevent the airflow from flowing into or out of the guide cavity 24 through the side opening of the V-shaped structure. In some embodiments of the present application, baffles 22 may be arranged at the openings on both sides of the V-shaped structure to prevent the airflow from flowing into or out of the guide cavity 24 through the openings on both sides of the V-shaped structure.

[0062] Combination Figure 2 and Figure 7 As shown, in some embodiments of the present application, the air conditioner indoor unit 1 also includes a sensor bracket 40, which is arranged at the vent, and an installation cavity is formed inside the sensor bracket 40, in which the temperature detection component 30 is arranged, and the outside and inside of the guide cavity 24 are respectively connected to the installation cavity.

[0063] Specifically, the interior of the sensor bracket 40 is formed with an installation cavity for installing the temperature detection element 30. By placing the temperature detection element 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. Figure 4 Alternatively, the airflow outside the guide cavity 24 can flow into the guide cavity 24 through the mounting cavity, as shown in FIG. Figure 7 As shown, the airflow can contact the temperature detection member 30 during the flow in the installation cavity, so that the airflow temperature is detected by the temperature detection member 30.

At the same time, the through hole structure that penetrates the sensor bracket 40 facilitates the airflow to flow into or out of the guide cavity 24, and then facilitates the detection of the airflow temperature through the temperature detection member 30.

[0066] Combination Figures 3 to 7 As shown, 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 the inside of the guide cavity 24 are respectively connected to the installation cavity through the first through holes 411.

[0067] By providing a plurality of first through holes 411, it is convenient for airflow to flow into or out of the mounting hole 43, thereby facilitating the airflow to contact the temperature detection member 30. When the sensor bracket 40 is plugged into the vent, a portion of the sensor bracket 40 provided with the first through holes 411 can be provided in the flow guide cavity 24, and another portion of the sensor bracket 40 provided with the first through holes 411 can be provided outside the flow guide cavity 24, so that the mounting hole 43 communicates with the inside and outside of the flow guide cavity 24 through the first through holes 411 on both sides of the axial direction.

[0069] Specifically, the support frame 50 is used to fix and install the sensor bracket 40. The support frame 50 can be a bent plate-like structure, a part of the plate-like structure is connected to the baffle 22, and another part of the plate-like structure is spaced apart from the baffle 22, so as to facilitate the installation and fixing of the sensor bracket 40. Among them, one end of the support frame 50 away from the first opening 241 is open, so as to facilitate the airflow to flow out of or into the guide cavity 24.

[0070] Combination Figure 4 , Figure 7 and Figure 8 As shown, 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 plugged into the vent, and the plug-in portion 41 is provided with a plurality of first through holes 411 spaced along its own axial direction and radial direction, respectively, and 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, and a part of the structure of the support frame 50 can be plugged into the positioning groove 421, so that the sensor bracket 40 is fixed 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 the installation process, which is convenient for installation. The positioning groove 421 is an annular groove, and a circular mounting hole is provided on the support frame 50, 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 is convenient for the positioning groove 421 to be clamped into the circular mounting hole on the support frame 50.
