Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioning technology, and in particular to a top-discharge type outdoor air conditioning unit. Background Technology
[0002] Top-discharge air conditioning outdoor units are a common type of air conditioning outdoor unit. In a top-discharge air conditioning outdoor unit, the outdoor air outlet is located at the top of the casing, the outdoor air inlet is located on the outer perimeter of the casing, the outdoor heat exchanger is installed along the height of the outdoor unit and extends along the inner peripheral wall of the casing, and the outdoor fan is located inside the casing and is positioned corresponding to the outdoor air outlet along the height of the casing. When the outdoor fan operates, it creates a negative pressure inside the casing, allowing outside air to enter the casing through the outdoor air inlet, exchange heat with the heat exchanger, and then be discharged to the outside of the casing through the outdoor air outlet.
[0003] For top-discharge air conditioner outdoor units, accurate ambient temperature detection is crucial. The air conditioning system needs to adjust its operating mode and parameters based on the outdoor ambient temperature to achieve efficient and energy-saving cooling and heating. Accurate ambient temperature detection provides the system with reliable data, allowing it to adjust its operating status in a timely manner and avoid operational abnormalities caused by changes in ambient temperature. This ensures that the air conditioner operates stably and efficiently under various conditions, meeting users' needs for a comfortable environment.
[0004] In existing technologies, temperature sensors used to detect ambient temperature are mounted on the casing via sensor brackets. There are various options for the installation location of the ambient temperature sensors and the design of the brackets. For example, some temperature sensors are installed on the outside of the casing, which not only affects the size and quantity of the packaging box, leading to increased shipping costs, but also poses a risk of damage during outdoor unit transportation. Some sensor brackets are poorly designed, resulting in cumbersome wiring for the temperature sensors. Other sensor brackets are poorly designed, with complicated installation steps requiring multiple operations, consuming time, resulting in low installation efficiency, poor stability, susceptibility to external factors, and a lack of effective protection for the temperature sensors, leading to easy damage, high maintenance costs, and short service life. These current problems affect the performance and reliability of air conditioners and urgently need improvement.
[0005] In view of the above, this application is hereby submitted. Utility Model Content
[0006] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore,
[0007] According to embodiments of this disclosure, a top-discharge air conditioning outdoor unit is provided, comprising:
[0008] A housing having an internal mounting cavity, the housing including an outdoor air outlet and an outdoor air inlet communicating with the mounting cavity, the outdoor air outlet and the outdoor air inlet being respectively located on the top and side of the housing;
[0009] An outdoor fan is installed inside the mounting cavity and located near the outdoor air outlet.
[0010] An outdoor heat exchanger is located inside the mounting cavity, and the outdoor heat exchanger is positioned close to the outdoor air inlet.
[0011] A compressor is disposed within the mounting cavity, and the compressor is located below the outdoor fan.
[0012] An electrical control box is connected to the housing and located outside the mounting cavity. The electrical control box has an internal cavity for accommodating the electrical control board. The electrical control box includes a base plate.
[0013] A temperature sensor, located outside the cavity, is used to detect the outdoor ambient temperature. The top of the temperature sensor is electrically connected to the control board via a sensor wiring harness.
[0014] A fixing hole is provided on the base plate and extends through the base plate along its thickness direction;
[0015] A mounting base is connected to the mounting hole, and the mounting base defines a clamping space for the sensor wiring to pass through. The mounting base includes:
[0016] The main body has an opening on its side wall;
[0017] The mounting part is connected to the opening. The mounting part and the body enclose the clamping space. The mounting part slides relative to the body in a direction perpendicular to the central axis of the clamping space so that the clamping space can be adjusted. The mounting part and the side opposite to each other of the body are provided with a snap-fit part, which snaps into the base plate from the fixing hole.
[0018] The above technical solution has the following advantages or beneficial effects: By placing the temperature sensor below the electrical control box, its location is concealed, not affecting the packing quantity, while effectively detecting the outdoor ambient temperature. By setting the mounting base as a separate sliding connection between the main body and the mounting part, the clamping space is adjustable. Simultaneously, corresponding snap-fit parts are provided on the main body and the mounting part, which, together with the sensor wiring, enable the mounting base to have a self-locking function. Specifically, when the snap-fit part snaps into the base plate through the fixing hole, the sensor wiring abuts against the hole wall through the mounting base. The snap-fit part and the two sides of the base plate adapt to form a bidirectional limit interlocking mechanism, ensuring stable installation of the mounting base and preventing loosening, thereby improving the installation reliability of the temperature sensor and enhancing installation efficiency and quality.
[0019] According to an embodiment of this disclosure, slide rails are provided on the two side walls of the main body facing each other, and sliding portions are provided on the two side walls of the mounting portion, the sliding portions being slidably connected in the slide rails.
[0020] The above technical solution has the following advantages or beneficial effects: by cooperating with the sliding part and the slide rail, the relative movement direction between the mounting part and the body is effectively restricted, preventing displacement in unexpected directions, enhancing the stability and reliability of the sliding connection, and further improving the clamping stability and installation convenience of the fixed seat.
[0021] According to an embodiment of this disclosure, there are guide slopes on the opposite sides of the two sliding portions, and the guide slopes are located at the end of the sliding portion near the sensor wiring.
[0022] The above technical solution has the following advantages or beneficial effects: the guide slope can guide the sliding part to smoothly enter the slide, making the adjustment of the clamping space size smoother and improving installation efficiency and convenience.
[0023] According to an embodiment of this disclosure, a protective cage is provided at the bottom of the main body, the protective cage is provided with a window, and the temperature sensor is disposed inside the protective cage.
[0024] The above technical solution has the following advantages or beneficial effects: by setting up a protective cage and placing the temperature sensor inside the protective cage, the temperature sensor can be effectively protected from being touched, meeting the safety requirements. The protective cage has windows, which facilitates airflow. Air flows into the protective cage and circulates fully within it, enabling the temperature sensor to accurately sense the air temperature and improving the detection accuracy of the outdoor ambient temperature.
[0025] According to an embodiment of this disclosure, the windows are located on opposite sides of the protective cage, and are arranged in a staggered manner along the length of the protective cage.
[0026] The above technical solution has the following advantages or beneficial effects: the staggered arrangement of windows can prevent air from passing directly through the protective cage, thereby avoiding the formation of blind spots in airflow within the protective cage, ensuring air circulation, and improving the sensing accuracy of the temperature sensor.
[0027] According to an embodiment of this disclosure, a guide portion is formed on the top of the fixing base corresponding to the snap-fit portion, and the guide portion is gradually widened in the direction from the top to the bottom of the fixing base.
[0028] The above technical solution has the following advantages or beneficial effects: by setting a guide part to guide the fixed seat when it is inserted into the fixed hole, the fixed seat can be inserted into the fixed hole more smoothly and accurately, reducing the alignment difficulties during the installation process and improving the installation efficiency.
[0029] According to an embodiment of this disclosure, the mounting portion has a protrusion on the side facing the clamping space, the protrusion is correspondingly provided with a snap-fit portion on the body, and the protrusion abuts against the sensor wiring.
[0030] The above technical solution has the following advantages or beneficial effects: the protrusion can increase the contact area and friction between the mounting part and the sensor wiring, thereby effectively preventing the sensor wiring from sliding in the clamping space, improving the fixing effect, and ensuring that the sensor wiring is fixed stably and reliably.
[0031] According to an embodiment of this disclosure, the outer periphery of the fixing seat is provided with a flange in the circumferential direction. When the fixing seat is inserted into the fixing hole, the flange is used to restrict the fixing seat from dislodging from the top of the fixing hole. A portion of the flange forms the bottom wall of the snap-fit portion.
[0032] The above technical solution has the following advantages or beneficial effects: by setting a flange, the fixing seat can be effectively prevented from coming out of the top of the fixing hole, significantly improving the installation stability of the fixing seat. Part of the flange forms the bottom wall of the locking part, enhancing the two-way interlocking effect between the fixing seat and the base plate, ensuring the reliability of the fixing seat during use.
[0033] According to an embodiment of this disclosure, the base plate is provided with a protrusion that protrudes toward the top of the housing, and the fixing hole is opened on the protrusion. The protrusion is circular and is a pressed structure on the base plate.
[0034] The above technical solution has the following advantages or beneficial effects: by setting the protrusion of the pressed structure, the strength of the part of the base plate around the fixing hole is increased, so that when the fixing seat is embedded in the fixing hole, the base plate can withstand greater pressure and is not easy to deform, thereby improving the load-bearing capacity and service life of the base plate.
[0035] According to embodiments of this disclosure, a top-discharge air conditioning outdoor unit is also provided, comprising:
[0036] A housing having an internal mounting cavity, the housing including an outdoor air outlet and an outdoor air inlet communicating with the mounting cavity, the outdoor air outlet and the outdoor air inlet being respectively located on the top and side of the housing.
[0037] An outdoor fan is installed inside the mounting cavity and located near the outdoor air outlet.
[0038] An outdoor heat exchanger is located inside the mounting cavity, and the outdoor heat exchanger is positioned close to the outdoor air inlet.
[0039] A compressor is disposed within the mounting cavity, and the compressor is located below the outdoor fan.
[0040] An electrical control box is connected to the housing and located outside the mounting cavity. The electrical control box has an internal cavity for accommodating the electrical control board. The electrical control box includes a base plate.
[0041] A temperature sensor, located outside the cavity, is used to detect the outdoor ambient temperature. The top of the temperature sensor is electrically connected to the control board via a sensor wiring harness.
[0042] A fixing hole is provided on the base plate and extends through the base plate along its thickness direction;
[0043] A mounting base is connected to the mounting hole, and a clamping space is defined within the mounting base. The sensor wiring passes through the clamping space and extends out of the mounting base from the top of the clamping space. The mounting base includes:
[0044] The main body has an opening on its side wall;
[0045] The mounting part is connected to the opening and together with the body defines the clamping space. The mounting part is slidably connected to the body along the radial direction of the sensor wiring. A snap-fit part is provided on the side of the mounting part away from the clamping space.
[0046] When the mounting base is installed, the mounting part slides and presses the sensor wiring into the clamping space along the radial direction, and the mounting base is pushed into the fixing hole from bottom to top; when the mounting base is pushed in until the snap-fit part corresponds to the fixing hole, the sensor wiring springs back and drives the snap-fit part to abut against the base plate to form a two-way limiting interlock structure.
[0047] The above technical solution offers the following advantages or beneficial effects: By placing the temperature sensor below the electrical control box, its location is concealed, not affecting the packing quantity, while effectively detecting the outdoor ambient temperature. During installation, simply press the mounting part inwards and push the mounting base from bottom to top into the fixing hole to complete the installation. The sensor wiring springs back, and the locking part enables the mounting base to self-lock, preventing it from moving vertically. This ensures the reliability of both the mounting base and the temperature sensor installation, effectively improving installation efficiency and quality. Attached Figure Description

[0070] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.
[0071] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.
[0072] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.
[0073] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.
[0074] The top-discharge air conditioning outdoor unit provided in this application can have various implementation forms. For example... Figures 1 to 20This is a specific embodiment of the top-discharge air conditioner outdoor unit of this application. The top-discharge air conditioner outdoor unit serves as the outdoor unit of the air conditioner, used to transfer heat from the indoor environment to the outdoor environment.
[0075] like Figure 1 As shown, the top-discharge air conditioner outdoor unit provided in this application may include a housing 1. The housing 1 is installed outdoors, and the housing 1 forms the overall appearance of the air conditioner outdoor unit 100.
[0076] The housing 1 defines a mounting cavity for installing and securing the various components of the outdoor unit 100 of the air conditioner. (Refer to...) Figure 1 The housing 1 has a top and a bottom, and the top and bottom of the housing 1 are opposite ends in the height direction of the housing 1.
[0077] The housing 1 may include an outdoor air outlet 12, which is located at the top of the housing 1. The outdoor air outlet 12 communicates with the mounting cavity and serves as an outlet for the heat-exchanged air to flow out from inside the housing 1.
[0078] The housing 1 may include an outdoor air inlet 11, which is located on the side wall of the outer periphery of the housing 1. The outdoor air inlet 11 communicates with the mounting cavity and serves as the inlet for external air to flow into the housing 1.
[0079] refer to Figure 1 , Figure 2 In this embodiment, the air outlet 12 is positioned so that its air outlet direction intersects with the air inlet 11.
[0080] like Figure 1 As shown, the housing 1 may include a top cover 13, which is located at the top of the housing 1, and an outdoor air outlet 12 is formed on the top cover 13. In this embodiment, the outdoor air outlet 12 is circular and located in the middle of the top cover 13.
[0081] The housing 1 may include a side panel 15, which surrounds the edge of the top cover 13. For example... Figure 2 As shown, the side panel 15 is located below the top cover 13, and the outdoor air inlet 11 is opened on the side panel 15.
[0082] The top cover 13 can be detachably connected to the side plate 15 by means of bolts or screws.
[0083] like Figure 2 As shown, the housing 1 may include a chassis 14, and the chassis 14 and the top cover 13 are disposed opposite each other along the height direction of the housing. The chassis 14 is connected to the lower part of the side plate 15, and the chassis 14, the side plate 15 and the top cover 13 together define and enclose to form a mounting cavity.
[0084] In some embodiments, the top cover 13 is connected to an air guide ring, which is located at the outdoor air outlet 12.
[0085] The air guide ring internally defines a cavity extending along the height direction of the casing 1. The impeller of the outdoor fan 3 is located inside the cavity. The air guide ring is used to guide the airflow within the installation cavity, enabling the outdoor fan 3 to better perform its air guiding function.
[0086] In some embodiments, the air guide ring can be integrally formed with the top cover 13 to facilitate the manufacturing and assembly of the outdoor unit of the air conditioner.
[0087] like Figure 1 As shown, an air outlet shroud 16 is connected to the casing 1. The air outlet shroud 16 is located at the outdoor air outlet 12 and covers the outside of the air guide ring. The air outlet shroud 16 can guide the airflow to be discharged in a specific direction. By optimizing the airflow path, the air outlet shroud 16 ensures that the heat exchange air discharged by the air conditioner can be quickly dispersed, reducing the energy loss during the operation of the outdoor unit 100 of the air conditioner and improving the performance and energy efficiency of the air conditioning system.
[0088] In some embodiments of this application, such as Figure 3 As shown, the outdoor unit of a top-discharge air conditioner may include an outdoor heat exchanger 2, which is located in the mounting cavity for heat exchange with the air inside the casing 1. The outdoor heat exchanger 2 is mounted on the chassis 14 and is positioned near the outdoor air inlet 11.
[0089] Continue to refer to Figure 4 The outdoor heat exchanger 2 is installed inside the outdoor air inlet 11 to exchange heat with the outdoor air entering the installation cavity through the outdoor air inlet 11.
[0090] The outdoor heat exchanger 2 extends along the inner peripheral wall of the casing 1 within the mounting cavity to increase the heat exchange area of the outdoor heat exchanger 2 within the mounting cavity, thereby increasing the heat exchange effect of the outdoor heat exchanger 2.
[0091] In this embodiment, the outdoor heat exchanger 2 is installed on the chassis 14, and the outdoor heat exchanger 2 is enclosed on the chassis 14 to form a semi-enclosed heat exchange space, which increases the area of the outdoor heat exchanger 2 and thus increases the heat exchange effect of the outdoor heat exchanger 2.
[0092] In some embodiments of this application, the outdoor unit 100 of the air conditioner may include an outdoor fan 3. The outdoor fan 3 is disposed in the mounting cavity and is used to drive outdoor air outside the housing 1 into the mounting cavity through the outdoor air inlet 11, and drive the air in the mounting cavity to flow along the outdoor air inlet 11 toward the outdoor air outlet 12.
[0093] The outdoor fan 3 is correspondingly installed with the outdoor air outlet 12. (Reference) Figure 2 The outdoor fan 3 is located inside the outdoor air outlet 12.
[0094] Outdoor fan 3 can be an axial flow fan. When an axial flow fan is used in the outdoor unit 100 of an air conditioner, its low aerodynamic noise and high air volume can improve the performance of the outdoor unit, thereby improving the performance of the entire air conditioning system.
[0095] The outdoor unit 100 of the air conditioner may include a compressor 4, which is disposed in a mounting cavity within the housing 1. (Continue to refer to...) Figure 4 The compressor 4 is mounted on the chassis 14 and located below the outdoor fan 3.
[0096] An air conditioner may include an indoor unit, also known as an indoor air conditioning unit, which is installed indoors and used for heat exchange with the indoor environment. The indoor air conditioning unit includes an indoor heat exchanger.
[0097] The air conditioner may include a throttling device for flow control. The throttling device may be located in the indoor unit of the air conditioner or in the outdoor unit 100 of a top-discharge air conditioner.
[0098] An air conditioner may include a refrigerant circuit. A refrigerant circuit is formed by connecting pipes to the indoor unit and the top-discharge outdoor unit 100 of the air conditioner, allowing the refrigerant to circulate sequentially through the compressor 4, condenser, throttling device, and evaporator, thus enabling indoor cooling or heating.
[0099] The indoor heat exchanger and outdoor heat exchanger 2 are used as condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in cooling mode.
[0100] Refrigeration and heating cycles include compression, condensation, expansion, and evaporation processes. They provide cooling or heating to the indoor space through the heat absorption and release processes of the refrigerant, thereby regulating the temperature of the indoor space.
[0101] Compressor 4 compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas, which then flows into the condenser.
[0102] The condenser condenses the compressed, high-temperature, high-pressure gaseous refrigerant into a liquid refrigerant, and the heat is released to the surrounding environment through the condensation process.
[0103] The liquid refrigerant flowing out of the condenser enters the throttling device, which expands the high-temperature, high-pressure liquid refrigerant after condensation in the condenser into a low-pressure liquid refrigerant.
[0104] The low-pressure liquid refrigerant flowing out of the throttling device enters the evaporator. As the liquid refrigerant flows through the evaporator, it absorbs heat and evaporates into a low-temperature, low-pressure refrigerant gas. The low-temperature, low-pressure refrigerant gas returns to the compressor 4.
[0105] The evaporator achieves its cooling effect by exchanging heat with the material being cooled using the latent heat of refrigerant evaporation. Throughout this entire cycle, the air conditioner regulates the temperature of the indoor space.
[0106] In some embodiments of this application, the chassis 14 may be a quadrilateral structure with chamfered corners, and the housing 1 may be a generally cuboid structure.
[0107] The outdoor unit of a top-discharge air conditioner may include an electrical control box 5, which is mounted on the housing 1 and located outside the mounting cavity. For example... Figure 2 As shown, the electrical control box 5 is positioned above the chamfered corner of the chassis 14.
[0108] The inside of the electrical control box 5 has a receiving cavity for accommodating the electrical control board 52.
[0109] It is understandable that the electrical control board 52 contains the electrical components required for the operation of the outdoor unit of the air conditioner. This is prior art in the field and will not be described in detail here.
[0110] refer to Figure 5 The electrical control box 5 may include a base plate 51, which forms the bottom wall 742 of the receiving cavity. The base plate 51 is perpendicular to the height direction of the housing.
[0111] In some embodiments of this application, the outdoor unit of a top-discharge air conditioner may include an ambient temperature detection component for detecting the outdoor ambient temperature. The ambient temperature detection component may include a temperature sensor 9, which is located outside the housing cavity.
[0112] It is understood that a sensor wiring 8 is provided at one end of the temperature sensor 9, and the other end of the sensor wiring 8 is electrically connected to the electronic control board 52 to enable communication between the temperature sensor 9 and the electronic control board 52. The temperature sensor 9 and the electronic control board 52 can communicate bidirectionally.
[0113] In related technologies, temperature sensors 9 that detect outdoor ambient temperature are mostly installed on the outside of the machine casing through a fixed structure. The fixed structure is complex, which is not conducive to the installation of the ambient temperature sensor. It not only affects the packing quantity, but also increases the risk of damage during machine transportation.
[0114] To solve the above-mentioned technical problems, in this embodiment, the top-discharge air conditioner outdoor unit may include a fixing base 7, which is installed on the base plate 51 and is used to install and support the temperature sensor 9.
[0115] refer to Figures 6 to 11 A fixing hole 6 is provided through the base plate 51 for mounting the fixing seat 7. The base plate 51 provides a basic support point for the mounting seat 7, ensuring the stability of the fixing seat 7 and the temperature sensor 9.
[0116] refer to Figure 12 The fixing base 7 has a clamping space 75 for clamping the sensor wiring 8, and the clamping space 75 allows the sensor wiring 8 to pass through and be clamped.
[0117] refer to Figures 13-15 The fixing base 7 may include a body 71, and the side wall of the body 71 is provided with an opening 711.
[0118] The opening 711 provides a structural basis for the installation of the subsequent mounting part 72 and the adjustability of the clamping space 75, making it easy to adjust the size of the clamping space 75.
[0119] Specifically, the mounting base 7 may include a mounting part 72, which is located at the opening 711. The mounting part 72 and the main body 71 enclose a clamping space 75. The clamping space 75 is arranged through the height direction of the housing.
[0120] The mounting part 72 slides relative to the main body 71. (Reference) Figure 16 The mounting part 72 slides along a direction perpendicular to the central axis of the clamping space 75, so that the size of the clamping space 75 can be adjusted. Specifically, by pressing the mounting part 72, the clamping space 75 can be reduced, thereby enabling the fixing base 7 to clamp the sensor wiring 8.
[0121] In this embodiment, by providing a dedicated fixed position for the sensor wiring 8, the sensor wiring 8 can be reliably clamped, preventing the sensor wiring 8 from becoming loose or shaking and interfering with the normal operation of the temperature sensor 9.
[0122] Further reference Figure 18 The mounting part 72 and the body 71 are provided with a snap-fit part 74 on their opposite sides, and the snap-fit part 74 snaps into the base plate through the fixing hole 6.
[0123] It is understandable that the snap-fit part 74 is adapted to the wall of the fixing hole 6 so that the fixing seat 7 is embedded in the fixing hole 6, and the base plate 51 is limited in the snap-fit part 74.
[0124] During installation, the mounting part 72 slides radially into the clamping space 75 (sliding along direction F) to press the sensor wiring 8, and pushes the mounting base 7 into the fixing hole 6 from bottom to top. When the mounting base 7 is pushed in until the snap-fit part 74 corresponds to the fixing hole 6, the sensor wiring 8 springs back to drive the snap-fit part 74 to snap into the base plate 51, forming a bidirectional limit interlock structure.
[0125] In this embodiment, when installing the mounting base 7, simply press the mounting part 72 to squeeze the sensor wiring 8 inward and push the mounting base 7 from bottom to top into the fixing hole 6 to complete the installation of the mounting base 7. When the mounting base 7 is pushed in until the locking part 74 corresponds to the fixing hole 6, the sensor wiring 8 springs back, and the locking part 74 enables the mounting base 7 to self-lock, preventing the mounting base 7 from moving vertically.
[0126] refer to Figure 17 When the mounting base 7 is in the assembled state, the sensor wiring 8 at the top of the temperature sensor 9 passes through the clamping space 75 and extends out of the mounting base 7 from the top of the clamping space 75 to connect to the electronic control board 52. This setting simplifies the wiring requirements of the sensor wiring, allowing the sensor wiring 8 at the top of the temperature sensor 9 to be directly connected to the electronic control board 52 through the mounting base, making the wiring of the sensor wiring 8 simple and convenient.
[0127] When the snap-fit part 74 is adapted to the fixing hole 6, the sensor wiring 8 abuts against the fixing seat 7, and the fixing seat 7 abuts against the hole wall of the fixing hole 6. The snap-fit part 74 and the two sides of the base plate 51 are adapted to form a two-way limiting interlocking mechanism, so that when the fixing seat 7 is embedded in the fixing hole 6.
[0128] Furthermore, the sensor wiring 8 abuts against the walls of the mounting base 7 and the mounting hole 6 in sequence, ensuring a tight fit between the temperature sensor 9 and the mounting base 7. This increases the friction between the temperature sensor 9 and the mounting base 7, preventing the temperature sensor 9 from easily detaching from the mounting base 7. The cooperation between the mounting base 7 and the mounting hole 6 allows for quick installation and fixation of the mounting base 7 on the base plate 51, ensuring the reliability of the installation of the mounting base 7 and the temperature sensor 9. This effectively improves the installation efficiency and quality of the ambient temperature detection component and facilitates disassembly and maintenance.
[0129] refer to Figure 10 After the mounting base 7 is installed, the temperature sensor 9 is fixed to the bottom of the body 71 through the sensor wiring 8 and the mounting base 7, and the temperature sensor 9 is located outside the receiving cavity.
[0130] In this embodiment, by placing the temperature sensor 9 below the electrical control box 5, its location is concealed, which does not affect the packing quantity while effectively detecting the outdoor ambient temperature. Simultaneously, placing the temperature sensor 9 below the electrical control box 5 shortens the length of the sensor wiring 8, facilitating wiring and connection arrangements, and saving costs.
[0131] In this embodiment, a snap-fit portion 74 is provided on the outer side of the mounting portion 72, and a snap-fit portion 74 is also provided on the outer side of the main body 71 opposite to the mounting portion 72. The two snap-fit portions 74 are arranged opposite each other, so that when the mounting portion 72 is pressed, the distance between the two snap-fit portions 74 becomes smaller, thereby allowing the fixing seat 7 to be smoothly inserted into the fixing hole 6.
[0132] By providing corresponding snap-fit parts 74 on the main body 71 and the mounting part 72, and in conjunction with the sensor wiring 8, the mounting base 7 can have a self-locking function, ensuring that the mounting base 7 is installed stably and is not easy to loosen, thereby improving the installation reliability of the temperature sensor 9 and improving installation efficiency and quality.
[0133] In some other embodiments, the snap-fit portion 74 may be provided only on the outer side of the mounting portion 72. This arrangement can still achieve the self-locking function of the fixing seat 7, but the stability is slightly worse than that described above, where the snap-fit portion 74 is provided on both the mounting portion 72 and the main body 71.
[0134] In some embodiments of this application, slide rails 712 are provided on the two side walls of the body 71 facing each other, and sliding parts 722 are provided on the two side walls of the mounting part 72, with the sliding parts 722 slidably connected in the slide rails 712.
[0135] In this embodiment, the sliding part 722 cooperates with the slide rail 712 to provide a stable and directional sliding trajectory for the mounting part 72, preventing the mounting part 72 from shifting in an unexpected direction. This ensures that the mounting part 72 can slide smoothly and accurately relative to the body 71 in a predetermined direction, which not only enhances the stability and reliability of the sliding connection of the mounting part 72, but also ensures the smoothness and accuracy of the adjustment of the size of the clamping space 75.
[0136] refer to Figure 14 , Figure 19 The sliding part 722 protrudes from the mounting part 72, and the slide rail 712 is a groove structure recessed on the two opposing side walls of the body 71. In this embodiment, the end of the slide rail 712 away from the sensor wiring 8 has an opening.
[0137] In some embodiments of this application, there are guide slopes 76 on the opposite sides of the two sliding portions 722, and the guide slopes 76 are located at one end of the sliding portion 722 near the sensor wiring 8.
[0138] In this embodiment, the guide slope 76 can guide the sliding part 722 to smoothly enter the slide rail 712, making the size adjustment of the clamping space 75 smoother and improving installation efficiency and convenience.
[0139] refer to Figure 20 The distance between the two guide ramps 76 is reduced in the direction F in which the mounting part 72 moves toward the clamping space 75.
[0140] In some embodiments of this application, a protective cage 73 is provided at the bottom of the body 71, and the temperature sensor 9 is disposed inside the protective cage 73.
[0141] By setting up the protective cage 73, the temperature sensor 9 is effectively protected. Placing the temperature sensor 9 in the protective cage 73 can effectively protect the temperature sensor 9 from being touched, meet the safety requirements, prevent damage to the sensor from external mechanical impacts, impurities, etc., extend the service life of the sensor, and ensure its measurement accuracy and stability.
[0142] refer to Figure 15 The protective cage 73 is equipped with a window 731, which facilitates the contact between the temperature sensor 9 and the external environment and promotes air circulation. The air flowing into and circulating freely within the protective cage 73 allows the temperature sensor 9 to accurately sense the air temperature, improving the accuracy of outdoor temperature detection. This also helps reduce the weight of the protective cage 73, avoiding unnecessary strain on the base plate 51.
[0143] Furthermore, windows 731 are located on opposite sides of the protective cage 73. This arrangement allows air to circulate inside the protective cage 73, accelerating the air exchange between the inside and outside of the protective cage 73. This enables the temperature sensor 9 to sense changes in the ambient temperature more promptly and accurately, thereby improving the sensitivity and accuracy of temperature measurement.
[0144] Continue to refer to Figure 15 Along the length of the protective cage 73, the windows 731 are arranged in a staggered pattern. That is, the windows 731 located on opposite sides of the protective cage 73 are staggered.
[0145] In this embodiment, by setting staggered windows 731, multiple ventilation channels can be formed along the length of the protective cage 73, further enhancing air circulation and avoiding blind spots in airflow within the protective cage 73, thus improving the sensing accuracy of the temperature sensor 9. Simultaneously, the staggered window design 731 also helps to improve the structural strength of the protective cage 73, preventing a decrease in overall strength due to excessively large or concentrated windows 731, thus better balancing protective performance and breathability.
[0146] In some embodiments of this application, a guide portion 77 is formed on the corresponding snap-fit portion at the top of the fixing base 7.
[0147] The guiding function of the guide part 77 makes it easier to align the fixing seat 7 with the fixing hole 6 when it is inserted, avoiding installation difficulties caused by direct contact between the outer periphery of the fixing seat 7 and the wall of the fixing hole 6, reducing the difficulty of centering during installation and improving installation efficiency.
[0148] refer to Figure 19 The guide section 77 is gradually widened from its top to its bottom.
[0149] When the gradually expanding guide portion 77 is inserted into the fixing hole 6, its narrower top part can easily enter the fixing hole 6 first. As the insertion depth increases, the outer wall of the body gradually contacts the hole wall and generates a certain squeezing and guiding effect, so that the fixing seat 7 can enter the fixing hole 6 more smoothly and naturally until the snap-fit portion 74 corresponds to the hole wall of the fixing hole 6. No large external force is required, which further improves the convenience and reliability of installation.
[0150] Of course, in some other embodiments, a guide portion is formed on the outer periphery of the top of the fixing base 7 in the circumferential direction. The guide portion 77 is gradually widened in the direction from the top to the bottom of the fixing base 7.
[0151] In this embodiment, reference Figure 18 , Figure 19 In some embodiments, the mounting portion 72 is provided with a protrusion 721 on the side facing the clamping space 75, and the protrusion 721 is provided corresponding to the snap-fit portion 74 on the body 71.
[0152] Among them, the protrusion 721 abuts against the sensor wiring 8.
[0153] In this embodiment, the protrusion 721 can increase the contact area and friction between the mounting part 72 and the sensor wiring 8, thereby effectively preventing the sensor wiring 8 from sliding in the clamping space 75, improving the fixing effect, and ensuring that the sensor wiring 8 is fixed stably and reliably.
[0154] As a localized force application point, the protrusion 721 can more precisely clamp the wiring and improve clamping stability. During the installation of the mounting base 7, when the protrusion 721 is used to press the wiring, the wiring can be more stably positioned in a specific location within the clamping space 75, reducing the movement or shaking of the wiring within the clamping space 75.
[0155] In some embodiments of this application, a flange 78 is provided on the outer periphery of the fixing seat 7 in the circumferential direction. When the fixing seat 7 is inserted into the fixing hole 6, the flange 78 is used to prevent the fixing seat 7 from dislodging from the top of the fixing hole 6.
[0156] The flange 78 is designed to limit the fixing seat 7 from below after it is inserted into the fixing hole 6, preventing the fixing seat 7 from coming out of the top of the fixing hole 6 due to upward external force during use, thus improving the stability of the fixing seat 7 during installation.
[0157] Understandably, during installation or disassembly, even if a large pressure is applied to the mounting part 72 to reduce the clamping space 75, the flange 78 on the body 71 can still play a limiting role, effectively preventing the fixing seat 7 from accidentally coming off due to improper operation.
[0158] Among them, reference Figure 15 , Figure 19 The flange 78 partially forms the bottom wall 742 of the snap-fit portion 74.
[0159] In this embodiment, part of the flange 78 is designed to form the bottom wall 742 of the snap-fit part 74, which enhances the bidirectional interlocking effect between the fixing seat 7 and the base plate 51 and ensures the reliability of the fixing seat 7 during use.
[0160] Continue to refer to Figure 19 The snap-fit portion 74 may include a top wall 741. The top wall 741 and the bottom wall 742 of the snap-fit portion 74 are disposed opposite each other along the thickness direction of the base plate 51.
[0161] The engaging portion 74 may include an abutment wall 743. The top and bottom ends of the abutment wall 743 are respectively connected to the opposite ends of the top wall 741 and the bottom wall 742 of the engaging portion 74.
[0162] refer to Figure 18 , Figure 19 After the mounting base 7 is installed, the abutment wall 743 abuts against the wall of the mounting hole 6. The top wall 741 of the snap-fit part 74 is located above the base plate 51, and the bottom wall 742 of the snap-fit part 74 is located below the base plate 51. The top wall 741 and the bottom wall 742 of the snap-fit part 74 cooperate to restrict the vertical movement of the mounting base 7.
[0163] The projected area of the top wall 741 of the snap-fit part 74 on the base plate 51 is smaller than the projected area of the bottom wall 742 of the snap-fit part 74 on the base plate 51.
[0164] The top wall 741 of the snap-fit part 74 has a small projected area, which allows the snap-fit part 74 to move smoothly to fit and connect with the fixing hole 6 when the fixing base 7 is inserted, reducing the installation difficulty. The bottom wall 742 of the snap-fit part 74 has a large projected area, providing a wider support surface, which allows the snap-fit part 74 to better abut against the bottom end of the base plate 51 after being inserted to a certain depth, ensuring the firmness of the snap-fit.
[0165] In some embodiments of this application, the base plate 51 is provided with a protrusion 511 that protrudes towards the top of the housing. A fixing hole 6 is formed on the protrusion 511.
[0166] The protrusion 511 provides a relatively high mounting position for the fixing hole 6, preventing condensation on the base plate 51 from flowing into the fixing hole 6 and affecting the normal operation of the temperature sensor 9.
[0167] refer to Figure 11 The protrusion 511 is circular and is a pressed structure on the base plate 51.
[0168] By setting the protrusion 511 of the pressed structure, the strength of the base plate 51 around the fixing hole 6 is increased, so that when the fixing seat 7 is inserted into the fixing hole 6, the base plate 51 can withstand greater pressure and is less prone to deformation, thereby improving the load-bearing capacity and service life of the base plate 51. At the same time, using the pressing process to manufacture the protrusion 511 can simplify the manufacturing process of the base plate 51, improve production efficiency and reduce production costs.
