[0002] In existing commercial air conditioning technology, there is no special snow-prevention device for the upper part of the top-outlet outdoor unit fan. This is a significant problem in heavy snow weather conditions in winter.

For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The following will Figures 1 - 5 describe the specific implementation manners of the top-air outlet air conditioner outdoor unit and the anti-snow accumulation method of the top-air outlet air conditioner outdoor unit of the present invention.

[0029] As Figure 1 and Figure 2 shown, the present invention provides a top-air outlet air conditioner outdoor unit, including a body 10, an electric heating component, a detection component, and a controller. Among them, an air outlet 11 is provided at the top of the body 10, and a fan component is provided in the air outlet 11; the electric heating component includes a top heating wire 21 disposed above the air outlet 11; the detection component includes a pressure sensor 31, and the pressure sensor 31 is disposed in the air outlet 11, and the pressure receiving surface of the pressure sensor 31 faces upward of the air outlet 11; the electric heating component is connected to the controller to control the heating state of the electric heating component through the controller, and the detection component is connected to the controller to send the pressure detection information of the pressure sensor 31 to the controller.

[0030] Among them, the body 10 serves as the basic structure of the outdoor air conditioner. An air outlet 11 is provided at the top of the body 10. The fan assembly installed inside the air outlet 11 of the body 10 is responsible for driving the air flow to achieve an efficient heat exchange process. The electric heating assembly mainly includes a top heating wire 21. The top heating wire 21 is arranged above the air outlet 11 and is preferably evenly distributed in a zigzag or other broken line shape above the air outlet 11. In the heavy snow weather in winter, the snow is melted by heating with the top heating wire 21, which can effectively prevent the air outlet 11 from being frozen or blocked due to snow cover, ensuring the normal air circulation and heat exchange.

[0031] In order to monitor the operating status of the outdoor air conditioner and environmental impacts in real time, the detection assembly at least includes a pressure sensor 31. The pressure sensor 31 is arranged at the air outlet 11, and the pressure receiving surface faces upward above the air outlet 11, so that the pressure sensor 31 can directly detect whether there is snow accumulation above it. When the snow accumulates to a certain extent and exerts pressure on the pressure sensor 31, the sensor can quickly capture this change and send relevant information to the controller.

[0032] The controller, as the center of the entire system, is responsible for coordinating the work of each component. The electric heating assembly is connected to the controller, and the heating state of the electric heating assembly can be flexibly controlled through the controller, such as starting or stopping heating, adjusting the heating temperature, etc. At the same time, the detection assembly is also connected to the controller and can send the pressure detection information of the pressure sensor 31 to the controller in real time. When the controller receives the snow pressure detection information reported by the pressure sensor 31, it can intelligently judge whether it is necessary to start the electric heating assembly for snow removal to ensure the smoothness of the air outlet 11 and the continuous normal operation of the outdoor air conditioner.

[0033] According to the above embodiments, the top-outlet outdoor air conditioner can automatically detect and handle the problem of blockage of the air outlet 11 in the snowy environment in winter, significantly improving the adaptability and reliability of the air conditioning system. Whether it is heavy snow weather or severe cold conditions, the outdoor air conditioner can maintain an efficient and stable working state, providing a comfortable indoor environment for users.

[0034] As Figure 1 、 Figure 2 and Figure 3 shown, according to a top-outlet outdoor air conditioner provided by the present invention, the fan assembly includes a fan bracket 12, and a wind guide opening 121 is provided on the fan bracket 12; the pressure sensor 31 is located outside the air outlet range of the wind guide opening 121. Among them, the function of the wind guide opening 121 is to cooperate with the fan blades arranged therein to guide the direction of the air flow leaving the outdoor air conditioner. In order to accurately detect whether the snow blocks the air outlet 11, the pressure sensor 31 is arranged outside the air outlet range of the wind guide opening 121, so that the pressure sensor 31 is not directly exposed to the air flow generated by the fan assembly, but is located in a relatively static area.

[0035] Specifically, it is preferably a circular opening that matches the movement of the fan blades and is located within the air outlet 11 at the top of the fuselage 10. The pressure sensor 31 is horizontally located outside the air guide opening 121 and within the air outlet 11. On the one hand, placing the pressure sensor 31 outside the air outlet range can prevent the air flow from directly impacting the sensor, thus ensuring the stability and accuracy of the sensor. On the other hand, since the pressure sensor 31 is not affected by the air flow, it can more sensitively capture the pressure change generated by the snow accumulation above the air outlet 11, issue an alarm in a timely manner, and activate the electric heating component to remove the snow.

[0036] Preferably, a plurality of pressure sensors 31 can be provided, and the plurality of pressure sensors 31 are evenly distributed around the air guide opening 121 to fully obtain the pressure detection information above the air outlet 11 and accurately judge the snow accumulation state.

[0037] As Figure 1 、 Figure 2 and Figure 3 shown, according to a top air outlet air conditioner outdoor unit provided by the present invention, a protective net 13 is provided on the air outlet 11; the above-mentioned pressure sensor 31 is arranged on the protective net 13. Among them, the protective net 13 is arranged on the air outlet 11, and its main purpose is to protect the components inside the air conditioner outdoor unit and prevent external objects such as floating garbage, leaves, small animals, etc. from entering the fan assembly, so as to ensure the cleanliness and normal operation of the air conditioning system. The protective net 13 can be made of a fine metal or plastic mesh material, which can effectively block foreign objects and allow air to pass through smoothly. Since the protective net 13 is located on the outermost side of the air outlet 11 and is in direct contact with the external environment, arranging the pressure sensor 31 on the protective net 13 can more directly detect the influence of snow accumulation on the air outlet 11. When snow accumulates on the protective net 13 and generates pressure on the pressure sensor 31, the sensor can quickly capture this change.

[0038] The pressure sensor 31 is preferably arranged on the inner side of the protective net 13, that is, the side facing the fuselage 10, so that under the protection of the protective net 13, the sensor can be prevented from being directly exposed to harsh weather conditions such as rain, snow, hail, etc., thereby extending the service life of the sensor and maintaining its detection accuracy.

[0039] Furthermore, as Figure 4 shown, according to a top air outlet air conditioner outdoor unit provided by the present invention, the protective net 13 includes heat-conducting wires 131 distributed in a cross shape; the top heating wires 21 are arranged on the protective net 13, and at least a part of the top heating wires 21 is attached to the heat-conducting wires 131. Among them, the heat-conducting wires 131 are preferably made of a metal or non-metal heat-conducting material.

[0040] Specifically, since the heat-conducting wire 131 can quickly transfer heat and reduce heat loss during the transfer process, the energy efficiency of the electric heating component can be improved and the energy consumption can be reduced. When the top heating wire 21 releases heat, the heat can be directly conducted to the heat-conducting wire 131 that is in contact with the top heating wire 21. The cross-distributed heat-conducting wires 131 can make the heat more evenly distributed on the protective net 13. When the top heating wire 21 starts heating, the heat can be quickly and evenly transferred to each part of the protective net 13 through the heat-conducting wire 131, improving the snow removal efficiency.

[0041] On the other hand, in addition to the implementation mode of setting the top heating wire 21 in contact with the heat-conducting wire 131, the top heating wire 21 can also replace part of the heat-conducting wire 131 so that the top heating wire 21 forms a part of the protective net 13.

[0042] According to an outdoor air conditioner with top air outlet provided by the present invention, the electric heating component includes a side heating wire 22; the side heating wire 22 vertically extends inside the side plate corner part 14 of the fuselage 10. As Figure 3 shown, the side plate corner part 14 of the fuselage 10 can also be a column structure distributed at the four corners of the fuselage 10.

[0043] Specifically, the top heating wire 21 in the above implementation mode mainly melts the snow above the air outlet 11, while the side heating wire 22 can prevent snow accumulation or icing at the side plate corner part 14 of the fuselage 10. Since the air inlet on the side plate is a key area for air flow and heat exchange, the accumulated snow or melted snow water may freeze here and affect the overall performance of the outdoor air conditioner. The setting of the side heating wire 22 is beneficial to preventing the melted snow water from freezing on the side of the fuselage 10 and preventing the accumulated snow around the fuselage 10 from being too high, ensuring the efficiency of air circulation and heat exchange. Since the side heating wire 22 is not directly exposed, the possibility of causing a safety accident due to contact with external objects is reduced.

[0044] Therefore, the design of the side heating wire 22 in the electric heating component vertically extending inside the side plate corner part 14 of the fuselage 10 is a further improvement and optimization of the snow protection function of the outdoor air conditioner. It can not only comprehensively prevent the influence of snow accumulation on each key part of the outdoor air conditioner, improve its operation efficiency and stability in the winter snow environment, but also take into account energy efficiency and safety, enhancing the comprehensive performance of the entire air conditioning system and the user experience.

[0045] Furthermore, as Figure 4As shown in the figure, a top - blowing air - conditioner outdoor unit provided by the present invention has a diversion channel 15 disposed between the fan assembly and the side plate of the body 10; the end of the diversion channel 15 leads to the inner side of the side - plate corner 14. When the top heating wire 21 releases heat and melts the snow at the air outlet 11, the diversion channel 15 can guide the melted snow water to flow along a preset path. In this way, the accumulation of snow water around the fan assembly can be avoided. The end of the diversion channel 15 leads to the inner side of the side - plate corner 14, which helps to centrally guide the melted snow water near the side heating wire 22. Under the heat - releasing effect of the side heating wire 22, it prevents the snow water from freezing again during the downward flow process.

[0046] A top - blowing air - conditioner outdoor unit provided by the present invention, the electric heating assembly includes a power supply unit; the top heating wire 21 and the side heating wire 22 are connected in series to the power supply unit, or the top heating wire 21 and the side heating wire 22 are respectively connected to the power supply unit to supply power to the top heating wire 21 and the side heating wire 22 respectively through the power supply unit.

[0047] Among them, the heat of the electric heating wire is generated after the current passes through the conductor. According to Joule's law, the heat generated by the current passing through the conductor is proportional to the resistance of the conductor, proportional to the square of the current passing through the conductor, and proportional to the energization time. When the current passes through the electric heating wire with a relatively large resistivity, heat will be generated. The electric heating wire itself is a kind of metal conductor, which will generate heat and release thermal energy after being energized. In order to prevent electric leakage, the outer surface of the electric heating wire is preferably wrapped with a heat - conducting insulating sleeve or insulating coating.

[0048] The above - mentioned power supply unit is responsible for converting the power supply into the voltage and current suitable for the operation of the top heating wire 21 and the side heating wire 22. When the top heating wire 21 and the side heating wire 22 are connected in series, when the power supply unit supplies power to the circuit, the top heating wire 21 and the side heating wire 22 will be heated simultaneously. When the top heating wire 21 and the side heating wire 22 are respectively connected to the power supply unit, the top heating wire 21 or the side heating wire 22 can be controlled and powered separately, so that the heating states and powers of the two heating wires can be independently adjusted and controlled.

[0049] Preferably, the power supply unit is connected to the controller, and according to the instructions of the controller, the power - supply states of the top heating wire 21 and the side heating wire 22 are respectively adjusted, and then the start or stop of the top heating wire 21 and the side heating wire 22 are respectively controlled, and the heat - releasing powers of the two are respectively adjusted.

[0050] As Figure 1 and Figure 3 As shown in the figure, a top - blowing air - conditioner outdoor unit provided by the present invention has a temperature sensor 32 disposed on the body 10; the temperature sensor 32 is disposed outside the air outlet 11, and the installation position of the temperature sensor 32 is adjacent to the air outlet 11.

[0051] Among them, the temperature sensor 32 is arranged outside the air outlet 11, and the installation position is adjacent to the air outlet 11. Therefore, it can directly sense and measure the ambient temperature at the air outlet 11 and quickly respond to the change of the temperature at the air outlet 11. The ambient temperature information at the air outlet 11 is monitored and fed back to the controller of the air-conditioning system by the temperature sensor 32. These temperature data will be used to determine whether to start or adjust the working state of the electric heating components (including the top heating wire 21 and the side heating wire 22) to prevent snow from freezing or to maintain a suitable air outlet temperature.

[0052] In combination with the ambient temperature information of the temperature sensor 32 and the pressure detection information of the pressure sensor 31, the controller can give a more accurate judgment on the snow accumulation state of the top air outlet air-conditioning outdoor unit.

[0053] As Figure 5 shown, the present invention also provides a method for preventing snow accumulation of a top air outlet air-conditioning outdoor unit, which is used to control the top air outlet air-conditioning outdoor unit of any of the above embodiments. The method includes:

[0054] Obtaining pressure detection information: First, the pressure sensor 31 installed at the air outlet 11 of the air-conditioning outdoor unit continuously monitors and obtains pressure detection information. The pressure sensor 31 is arranged at positions such as outside the protection net 13 or the air guide port 121 to detect whether snow accumulation affects the air outlet 11.

[0055] Judging the snow accumulation state of the air outlet of the air-conditioning outdoor unit according to the pressure detection information: According to the obtained pressure detection information, the controller performs data analysis and judgment to determine the snow accumulation state of the air outlet 11 of the air-conditioning outdoor unit. If the pressure value exceeds the preset threshold, this may indicate that snow is accumulated above the air outlet 11 and has a certain impact on the air outlet 11.

[0056] Controlling the heating state of the electric heating components according to the snow accumulation state: According to the judged snow accumulation state, the controller can automatically adjust the heating state of the electric heating components. Specifically, when snow accumulation is detected at the air outlet 11, the controller issues an instruction to start the electric heating components, including the top heating wire 21 and / or the side heating wire 22, to melt the snow. The heating state of the electric heating components can be turned on, turned off or the heating power can be adjusted to adapt to different snow accumulation degrees and environmental conditions.

[0057] Through the above method, the top-outlet air conditioner outdoor unit can automatically detect and address the problem of snow accumulation at the air outlet 11 in a snowy environment in winter. By continuously monitoring the pressure detection information and adjusting the working state of the electric heating component accordingly, the air conditioner outdoor unit can keep the air outlet 11 unobstructed, ensuring normal air circulation and heat exchange, thereby improving the adaptability and reliability of the air conditioning system. This anti-snow accumulation method not only improves the operating efficiency of the air conditioner outdoor unit under harsh weather conditions but also reduces equipment failures and maintenance costs caused by snow accumulation.

[0058] Furthermore, according to an anti-snow accumulation method for a top-outlet air conditioner outdoor unit provided by the present invention, in the step of judging the snow accumulation state of the air outlet 11 of the air conditioner outdoor unit based on the pressure detection information, it further includes: obtaining ambient temperature information; comprehensively judging the snow accumulation state of the air outlet 11 of the air conditioner outdoor unit according to the ambient temperature information and the pressure detection information. By introducing the ambient temperature information, the presence and degree of snow accumulation can be judged more accurately.

[0059] Specifically, the ambient temperature is an important factor affecting snow formation and melting. In a low-temperature environment, for example, when the ambient temperature is less than or equal to 0 degrees, even a slight pressure change shown by the pressure detection information may indicate that snow is starting to accumulate. On the contrary, in a higher ambient temperature, even with a certain pressure change, the snow may melt relatively quickly. Therefore, considering the ambient temperature helps to more precisely identify the snow accumulation state.

[0060] Combining the ambient temperature information and the pressure detection information, the controller can dynamically adjust the heating strategy of the electric heating component. For example, in a low-temperature situation with an obvious pressure change, the system may start or increase the heating power of the electric heating component more quickly to prevent the snow from freezing and accumulating rapidly. In a situation with a higher temperature and an unobvious pressure change, the system may reduce or delay the heating to save energy.

[0061] By obtaining the ambient temperature information and comprehensively judging the snow accumulation state of the air outlet 11 of the air conditioner outdoor unit, this method can improve the accuracy and adaptability of the judgment, ensure that the air conditioner outdoor unit operates more intelligently and efficiently in a snowy environment in winter, effectively prevent the snow from blocking the air outlet 11, and guarantee the normal operation of the air conditioning system and user comfort.

[0062] The above controller may include: a processor, a communication interface, a memory, and a communication bus. Among them, the processor, the communication interface, and the memory communicate with each other through the communication bus. The processor can call the logical instructions in the memory to execute the anti-snow accumulation method for the top-outlet air conditioner outdoor unit.

[0063] In addition, when the logical instructions in the above-mentioned memory can be implemented in the form of software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium. Based on such an understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, or a part of this technical solution, can be embodied in the form of a software product.
