Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor unit of an air conditioner. Background Technology

[0002] Wall-mounted air conditioners typically consist of two parts: an indoor unit and an outdoor unit. The outdoor unit is usually installed on an exterior wall, balcony, or roof, while the indoor unit is usually installed on an interior wall. The indoor unit draws in air through a heat exchange inlet on its casing, and after the air passes through the indoor heat exchanger, it is released into the room through the heat exchange outlet.

[0037] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0038] The indoor and outdoor units of an air conditioner are connected by pipes to transfer refrigerant. The indoor unit includes an indoor heat exchanger and a fan assembly (such as a heat exchange fan), while the outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan, and an expansion valve. The compressor, outdoor heat exchanger, expansion valve, and indoor heat exchanger connected in sequence form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor and indoor heat exchangers to achieve the air conditioner's cooling or heating mode.

[0039] An expansion valve connects the outdoor and indoor heat exchangers. The opening degree of the expansion valve regulates the refrigerant pressure flowing through both heat exchangers, thereby regulating the refrigerant flow rate between them. The flow rate and pressure of the refrigerant flowing between the outdoor and indoor heat exchangers affect their heat exchange performance. The expansion valve can be an electronic valve. Its opening degree is adjustable to control the flow rate and pressure of the refrigerant passing through it.

[0040] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the air conditioner, the outdoor heat exchanger operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0041] The following is for reference. Figures 1-10 The indoor unit 100 of the air conditioner according to an embodiment of the present utility model includes: a base 1, an outer cover 2, and an electrical control box assembly 3.

[0042] Specifically, the outer cover 2 is mounted on the base 1, and the outer cover 2 has ventilation holes 21; the electrical control box assembly 3 is mounted on the base 1, and part of the electrical control box assembly 3 is arranged opposite to the ventilation holes 21; the electrical control box assembly 3 is equipped with an ambient temperature sensor 31, which is arranged opposite to the ventilation holes 21, and the ambient temperature sensor 31 is used to detect the airflow at the ventilation holes 21; wherein, the electrical control box assembly 3 includes: an electrical control box 32 and a retaining plate 33, the electrical control box 32 is mounted on the base 1, the retaining plate 33 is snapped onto the outside of the electrical control box 32, and the ambient temperature sensor 31 is mounted on the retaining plate 33.

[0043] It is understandable that during the use of the indoor unit 100 of the air conditioner, it is suitable to be built in the indoor environment to improve the indoor environment and achieve the goal of improving the indoor environment.

[0044] In practical use, it is suitable to provide ventilation holes 21 on the outer cover 2 so that the air conditioner indoor unit 100 can circulate air through the ventilation holes 21 during use, so as to sense and detect the airflow and realize the detection feedback of the operation of the air conditioner indoor unit 100. Based on the detection results, the output performance of the air conditioner indoor unit 100 can be adjusted so that the air conditioner indoor unit 100 can better improve the quality of the indoor environment and improve the user's experience of using the air conditioner indoor unit 100.

[0045] In some specific embodiments, the indoor unit 100 of the air conditioner is adapted to include a base 1, an outer cover 2, and an electrical control box assembly 3. The base 1 is adapted to provide a load-bearing function to support other electrical structures within the indoor unit 100. The outer cover 2 is adapted to cover the base 1 to protect the other electrical structures mounted on the base 1, thereby making the structure of the indoor unit 100 more reliable. Simultaneously, the electrical control box assembly 3 is also adapted to be constructed within the outer cover 2. The electrical control box assembly 3 is adapted to control and adjust the operation of the indoor unit 100, so that the output performance of the indoor unit 100 can better adjust the indoor environmental quality, thereby improving the user's experience in the indoor environment.

[0046] During the use of the indoor unit 100 of the air conditioner, it is necessary to adjust the output performance of the indoor unit 100 according to demand. Therefore, the output performance of the indoor unit 100 needs to be tested. Thus, an ambient temperature sensor 31 can be installed inside the indoor unit 100 to test the output performance of the indoor unit 100 and transmit the test results to the control box assembly 3. The control box assembly 3 can then adjust the output performance of the indoor unit 100 based on the test results, thereby improving the user experience. A retaining plate 33 is suitable for being installed on one side of the control box 32. The ambient temperature sensor 31 is suitable for being mounted on one side of the control box 32 via the retaining plate 33, allowing the ambient temperature sensor 31 to detect the airflow flowing through the ventilation hole 21. The test results are relatively accurate and reliable, allowing the indoor unit 100 to better adjust its output performance based on the test results, thereby further improving the user experience of the indoor unit 100.

[0047] Furthermore, the control box assembly 3 is adapted to include a control box 32 and a mounting plate 33. The control box 32 is adapted to receive the detection results of the ambient temperature sensor 31 and adjust the output performance of the indoor unit 100 of the air conditioner according to the results. The mounting plate 33 is adapted to provide a position for the ambient temperature sensor 31, so that the ambient temperature sensor 31 can be connected to the mounting plate 33 to be arranged on one side of the control box 32. This makes the arrangement of the ambient temperature sensor 31 in the indoor unit 100 of the air conditioner simpler and more convenient, and the setting of the ambient temperature sensor 31 more reliable. This allows the ambient temperature sensor 31 to more reliably detect the ventilation at the ventilation hole 21, so that the output performance of the indoor unit 100 of the air conditioner can meet the indoor environment requirements, and the user experience of using the indoor unit 100 of the air conditioner is more comfortable. In addition, placing the mounting plate 33 on one side of the control box 32 can also prevent the mounting plate 33 from protruding from the plane of the control box 32 near the outer cover 2, so as to prevent interference during the assembly of the outer cover 2.

[0048] According to an embodiment of the present invention, the indoor unit 100 of the air conditioner has a retaining plate 33 on one side of the control box 32. The ambient temperature sensor 31 is adapted to be connected to the control box 32 via the retaining plate 33, allowing for a simpler and more reliable arrangement of the ambient temperature sensor 31 on the control box 32, thus making its use more stable and reliable. Furthermore, by using the retaining plate 33 to arrange the ambient temperature sensor 31 on one side of the control box 32, it can be positioned relative to the ventilation hole 21, enabling the ambient temperature sensor 31 to more accurately and reliably detect the output performance of the indoor unit 100 during use, thereby improving its detection accuracy. In addition, because the ambient temperature sensor 31's detection is more accurate, the indoor unit 100 can adjust its output performance based on the detection results, allowing for more reliable adjustment of the indoor unit's output performance to meet user needs and providing a more comfortable user experience. Meanwhile, placing the ambient temperature sensor 31 on the electrical control box 32 can avoid the influence of other structures on the use of the ambient temperature sensor 31 during use, thereby improving the accuracy of the ambient temperature sensor 31.

[0049] In some embodiments, the card plate 33 includes: a card plate body 331 and a limiting part 332. The limiting part 332 is movably connected to the card plate body 331, and the limiting part 332 is provided with a limiting groove 333. The limiting groove 333 is a recess and the ambient temperature sensor 31 is limited to the limiting groove 333.

[0050] In other words, during the construction of the card plate 33, it is suitable to include a card plate body 331 and a limiting part 332. The limiting part 332 is suitable to be movably connected to the card plate body 331, so that the limiting position of the limiting part 332 can be adjusted according to needs, so that the ambient temperature sensor 31 can be limited to the card plate body 331 by the limiting part 332. This simplifies the construction of the ambient temperature sensor 31 on the card plate 33, makes the assembly process of the ambient temperature sensor 31 simpler, and makes the setting of the ambient temperature sensor 31 on the card plate 33 more reliable. Moreover, it is suitable to construct a limiting groove 333 on the limiting part 332. The limiting groove 333 is a recess, so that the limiting groove 333 can limit the ambient temperature sensor 31, so that the ambient temperature sensor 31 can be limited to the card plate body 331 by the limiting groove 333, thereby improving the reliability of the arrangement of the ambient temperature sensor 31 on the card plate 33.

[0051] In some embodiments, an angle is formed between the extending direction of the limiting portion 332 and the extending direction of the card plate body 331, and the angle satisfies the relationship: 15°≤A≤45°. It is understood that during the construction of the limiting portion 332 and the card plate body 331, it is suitable to establish an angle between them. This angle is suitable for guiding the assembly process of the ambient temperature sensor 31, making the assembly of the ambient temperature sensor 31 on the card plate 33 simpler and more convenient, thereby improving assembly efficiency. Similarly, the angle should not be too large or too small. If the angle is too large, the limiting effect of the limiting portion 332 on the ambient temperature sensor 31 will be relatively poor, while if the angle is too small, the assembly of the ambient temperature sensor 31 between the limiting portion 332 and the card plate body 331 will be more difficult. Therefore, it is suitable to construct the included angle between 15° and 45° so that the ambient temperature sensor 31 can be easily assembled between the limiting part 332 and the card plate body 331, and the limiting part 332 has a relatively good limiting effect on the ambient temperature sensor 31. In some more specific embodiments, it is suitable to set the included angle between the extension direction of the limiting part 332 and the extension direction of the card plate body 331 to 30°, so that the assembly process of the ambient temperature sensor 31 on the card plate 33 is simple and reliable, so that the ambient temperature sensor 31 can be arranged at the ventilation hole 21 as designed to detect airflow, so that the detection results are more accurate and reliable.

[0052] In some embodiments, the pallet body 331 is provided with a connecting port 334, which is disposed opposite to the limiting part 332. It is understood that the connecting port 334 is adapted to be constructed on the pallet body 331 to simplify the demolding process of the pallet body 331 during production, thereby improving the production efficiency of the pallet body 331. Simultaneously, by adapting the connecting port 334 to be disposed opposite to the limiting part 332, after the ambient temperature sensor 31 is confined to the limiting part 332, the connecting port 334 is adapted to allow airflow, thereby enabling airflow to act on the ambient temperature sensor 31 through the connecting port 334, making the detection results of the ambient temperature sensor 31 more accurate and reliable during use.

[0053] In some embodiments, the bottom of the card plate 33 is provided with a cantilever 335, and the free end of the cantilever 335 is provided with a buckle 336. The electrical control box 32 is provided with a slot 321, and the buckle 336 is inserted into the slot 321, with the buckle 336 at the bottom of the slot 321. That is to say, during the process of connecting the card plate 33 to the electrical control box 32, since the slot 321 is constructed on the electrical control box 32, the buckle 336 on the card plate 33 can be engaged with the bottom of the slot 321 to realize the assembly of the card plate 33 on the electrical control box 32, and the assembly process of the card plate 33 is relatively simple. Meanwhile, since the card plate 33 is provided with a cantilever 335 and a buckle 336 is provided at the free end of the cantilever 335, during the snap-fit ​​process of the buckle 336, it is suitable to set the cantilever 335 inside the card slot 321, so that the snap-fit ​​area of ​​the card plate 33 on the electrical control box 32 is larger, thereby making the card plate 33 more reliably restricted on the electrical control box 32, so that the arrangement stability of the ambient temperature sensor 31 is higher, and the detection result of the ambient temperature sensor 31 is more accurate and reliable.

[0054] In some embodiments, the card plate 33 is further provided with a limiting protrusion 337 in the middle, and the limiting protrusion 337 is abutted against the top of the card slot 321. It can be understood that by providing a limiting protrusion 337 in the middle of the card plate 33, and by constructing the limiting protrusion 337 in an abutting manner on the top of the card slot 321, the limiting protrusion 337 can be fixed together with the buckle 336 to fix the card plate 33, thereby improving the reliability of the arrangement of the card plate 33 on the electrical control box 32.

[0055] In some embodiments, the electrical control box 32 is provided with a wire-holding groove 322 for holding the wiring harness of the indoor unit 100 of the air conditioner. The wire-holding groove 322 is provided with a first connecting hole 323, and the limiting boss 337 is provided with a second connecting hole 338. The first connecting hole 323 and the second connecting hole 338 are arranged opposite to each other and connected and fixed. That is to say, during the use of the indoor unit 100 of the air conditioner, it is suitable to construct a wiring harness to connect different electrical structures. Therefore, the wire-holding groove 322 is provided in the indoor unit 100 of the air conditioner. The wire-holding groove 322 is suitable for organizing and tidying up the wiring harness, so that the wiring harness arrangement of the indoor unit 100 of the air conditioner is simpler and more reliable. A first connecting hole 323 is suitable for being constructed on the wire-locking groove 322, so that the first connecting hole 323 can be fixedly connected to the second connecting hole 338 on the limiting boss 337. In this way, the connection and fixation between the wire-locking groove 322 and the limiting boss 337 improves the reliability of the arrangement of the wire-locking groove 322 and the locking plate 33 on the electrical control box 32, making the arrangement of the ambient temperature sensor 31 on the electrical control box 32 more reliable. This allows the ambient temperature sensor 31 to detect airflow as designed, so that the output performance of the air conditioner indoor unit 100 can meet the user's needs, thereby improving the user experience. In addition, a screw hole 360 ​​is also provided on the limiting boss 337, so that during the connection between the locking plate 33 and the wire-locking groove 322, the locking plate 33 and the wire-locking groove 322 can be restricted through the screw hole 360, making the connection restriction between the locking plate 33 and the wire-locking groove 322 more reliable.

[0056] In some embodiments, the card plate 33 is further provided with a limiting rib 339, the extension height of which is greater than the diameter of the ambient temperature sensor 31, and the ambient temperature sensor 31 is snapped and restricted inside the limiting mechanism. It is understood that during the setting of the ambient temperature sensor 31 on the card plate 33, it is suitable to restrict the ambient temperature sensor 31 by means of the limiting rib 339, so that the limiting rib 339 can restrict the setting of the ambient temperature sensor 31, and after the limiting part 332 restricts the ambient temperature sensor 31, it is suitable to further restrict the ambient temperature sensor 31 by means of the limiting rib 339, so that the setting of the ambient temperature sensor 31 on the card plate 33 is more reliable, and the detection of the ambient temperature sensor 31 is more accurate. Furthermore, the limiting part 332 and the limiting rib 339 are adapted to be constructed on both sides of the ambient temperature sensor 31, so that when the ambient temperature sensor 31 is set on the card plate 33, the limiting part 332 and the limiting rib 339 can restrict the setting of the ambient temperature sensor 31, thereby further improving the reliability of the ambient temperature sensor 31 on the card plate 33.

[0057] In some embodiments, a guide surface 340 is provided on the side of the limiting rib 339 away from the ambient temperature sensor 31, and the guide surface 340 is a guide slope. That is, a guide slope is also provided on the side of the limiting rib 339 away from the ambient temperature sensor 31. During the assembly process of the ambient temperature sensor 31, it is suitable to provide a guiding function through the guide slope so that the ambient temperature sensor 31 can be guided through the guide surface 340, thereby simplifying the assembly process and improving assembly efficiency.

[0058] Furthermore, during the construction of the card plate 33, it is also suitable to provide a flange 350 on the outer periphery of the card plate 33. The flange 350 is suitable to improve the structural strength of the card plate 33, so that the card plate 33 has higher performance to support the installation of the ambient temperature sensor 31. At the same time, it can also save the material of the card plate 33 and reduce the production cost of the card plate 33, thereby saving the production cost of the indoor unit 100 of the air conditioner.

[0059] An indoor unit 100 of an air conditioner according to an embodiment of the present utility model includes: a base 1, an outer cover 2, and an electrical control box assembly 3. The outer cover 2 is disposed on the base 1 and has ventilation holes 21. The electrical control box assembly 3 is disposed on the base 1, and a portion of the electrical control box assembly 3 is disposed opposite to the ventilation holes 21. An ambient temperature sensor 31 is disposed on the electrical control box assembly 3 and is disposed opposite to the ventilation holes 21. The ambient temperature sensor 31 is used to detect the airflow at the ventilation holes 21.

[0060] In practical use, it is suitable to provide ventilation holes 21 on the outer cover 2 so that the air conditioner indoor unit 100 can circulate air through the ventilation holes 21 during use, so as to sense and detect the airflow and realize the detection feedback of the operation of the air conditioner indoor unit 100. Based on the detection results, the output performance of the air conditioner indoor unit 100 can be adjusted so that the air conditioner indoor unit 100 can better improve the quality of the indoor environment and improve the user's experience of using the air conditioner indoor unit 100.

[0061] In some specific embodiments, the indoor unit 100 of the air conditioner is adapted to include a base 1, an outer cover 2, and an electrical control box assembly 3. The base 1 is adapted to provide a load-bearing function to support other electrical structures within the indoor unit 100. The outer cover 2 is adapted to cover the base 1 to protect the other electrical structures mounted on the base 1, thereby making the structure of the indoor unit 100 more reliable. Simultaneously, the electrical control box assembly 3 is also adapted to be constructed within the outer cover 2. The electrical control box assembly 3 is adapted to control and adjust the operation of the indoor unit 100, so that the output performance of the indoor unit 100 can better adjust the indoor environmental quality, thereby improving the user's experience in the indoor environment.

[0062] During the use of the indoor unit 100 of the air conditioner, it is necessary to adjust the output performance of the indoor unit 100 according to demand. Therefore, the output performance of the indoor unit 100 needs to be tested. Thus, an ambient temperature sensor 31 can be installed inside the indoor unit 100 to test the output performance of the indoor unit 100 and transmit the test results to the control box assembly 3. The control box assembly 3 can then adjust the output performance of the indoor unit 100 based on the test results, thereby improving the user experience. A retaining plate 33 is suitable for being installed on one side of the control box 32. The ambient temperature sensor 31 is suitable for being mounted on one side of the control box 32 via the retaining plate 33, allowing the ambient temperature sensor 31 to detect the airflow flowing through the ventilation hole 21. The test results are relatively accurate and reliable, allowing the indoor unit 100 to better adjust its output performance based on the test results, thereby further improving the user experience of the indoor unit 100.

[0063] According to an embodiment of this utility model, the indoor unit 100 of the air conditioner includes an ambient temperature sensor 31 housed within the outer casing 2. This ambient temperature sensor 31 can be easily and reliably arranged on the control box 32, achieving centralized placement of the sensor on the control box 32. Furthermore, by arranging the ambient temperature sensor 31 on one side of the control box 32, it can be positioned relative to the ventilation hole 21, allowing for more accurate and reliable detection of the output performance of the indoor unit 100 during use, thus improving its detection accuracy. In addition, the more accurate detection by the ambient temperature sensor 31 allows the indoor unit 100 to adjust its output performance based on the sensor's detection results. This more reliable adjustment ensures that the output performance of the indoor unit 100 meets the user's needs, resulting in a more comfortable user experience.
