[0035] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0036] like Figures 1 to 3 As shown, according to the first embodiment of the present application, an air guide ring 100 is proposed, including: an air guide ring body 110; and a heating element 120, which is arranged on the outer wall of the above-mentioned air guide ring body 110.

[0037] In the prior art, a sealing mesh cover is usually provided above the air duct of the air-conditioning outdoor unit 300 to reduce the amount of water flowing into the air duct, thereby reducing the amount of ice. However, when the air-conditioning outdoor unit 300 is in a cold environment, a small amount of water will still freeze and accumulate, causing the volume of ice to increase, thereby affecting the rotation of the fan blades, and the ice problem is not solved well.

[0038] It is understood that the air guide ring 100 provided in the embodiment of the present application is provided with an air guide ring body 110 and a heating element 120. The air guide ring body 110 can be provided on the panel 210 of the air conditioner housing 200, and the air flow in the air conditioner housing 200 is guided to the air outlet through the air guide ring body 110 to ensure smooth blowing. The heating element 120 can be provided on the outer wall of the air guide ring body 110, and heat exchange is performed between the heating element 120 and the outer wall of the air guide ring body 110 to increase the temperature of the air guide ring body 110, thereby ensuring that the air guide ring 100 of the air conditioner outdoor unit 300 does not freeze or melts the ice on the surface of the air guide ring 100 when the outdoor temperature is low or when it rains, snows, or freezes. This prevents excessive ice from forming on the air guide ring 100, which may affect the rotation of the fan blades of the air conditioner outdoor unit 300, causing abnormal noise or even damage to the blades. This improves the protection of the blades, ensures that the blades can operate continuously and stably, and improves reliability.

[0039] It should be noted that a waterproof layer may be provided on the outside of the heating element 120 to prevent rainwater from the external environment or water formed by melting ice on the surface of the air guide ring 100 due to heating of the air guide ring body 110 by the heating element 120, causing a short circuit in the heating element 120 and affecting the normal operation of the heating element 120, thereby improving protection.

[0040] In some examples, such as Figures 1 to 3 As shown, the heating element 120 includes an electric heating belt, which is sleeved around the outer wall of the air guide ring body 110 .

[0041] It is understandable that the heating element 120 can be an electric heating tape. The electric heating tape is relatively soft and easy to shape. The electric heating tape can be bent to match the shape of the air guide ring body 110 so that the electric heating tape can fit the outer wall of the air guide ring body 110. On the one hand, the heating area of the electric heating tape on the air guide ring body 110 can be increased, ensuring the heating effect of the electric heating tape. When the outdoor temperature of the air conditioner outdoor unit 300 is low, or in low temperature climates such as rain, snow, and freezing rain, the air guide ring 100 will not be frozen or the ice on the surface of the air guide ring 100 will be melted. On the other hand, the electric heating tape occupies a smaller area along the radial direction of the air guide ring body 110, avoiding excessive protrusion from the outer wall of the air guide ring body 110 and interference with other components, thereby improving reliability.

[0042] For example, the extended length of the electric heating tape is at least 50% of the outer diameter of the air guide ring body 110 to ensure the heating efficiency of the electric heating tape on the air guide ring body 110, so as to quickly remove the ice layer on the air guide ring body 110 and prevent further ice accumulation on the air guide ring body 110.

[0043] In some examples, such as Figures 1 to 3As shown, one end of the air guide ring body 110 used for connecting to the panel 210 is a connecting end, and the electric heating belt is arranged close to the connecting end.

[0044] It is understood that the air guide ring body 110 can be used to connect to the panel 210. The panel 210 can have an air outlet. The air guide ring 100 is connected to the air outlet to guide the airflow within the air conditioner housing 200 to the air outlet through the air guide ring body 110, ensuring smooth blowing. Among them, the end of the air guide ring body 110 that is connected to the panel 210 is the connection end. Since the air conditioner outdoor unit 300 is placed in an outdoor environment, when the air conditioner uses the heating function in a cold environment, the low-temperature airflow after heat exchange in the heat exchanger is transported to the air outlet through the air guide ring 100, making the temperature of the air guide ring body 110 near the panel 210 lower than the temperature of the area far from the panel 210, making it more prone to ice formation. Therefore, an electric heating belt is set near the connection end of the air guide ring body 110 to ensure a heating effect on the area prone to ice formation, so as to quickly remove the ice layer on the air guide ring body 110 and prevent further ice accumulation on the air guide ring body 110.

[0045] It should be noted that the outer diameters of the connecting end and the opposite end of the air guide ring body 110 are larger than the outer diameter of the middle section of the air guide ring body 110. The electric heating tape can be installed in the middle section near the connecting end. Once the electric heating tape is installed, its outer diameter is less than or equal to the outer diameters of the connecting end and the opposite end. This prevents the electric heating tape from protruding from the air guide ring body 110 and interfering with other components, ensuring the normal operation of the air conditioner outdoor unit 300.

[0046] In some examples, the air guide ring 100 further includes a fixing member, through which the electric heating belt is fixed to the air guide ring body 110 .

[0047] It is understandable that the air guide ring 100 may also be provided with fixings. Specifically, the electric heating tape may be fixed to the air guide ring body 110 by fixings to prevent the electric heating tape from shaking or even falling off from the air guide ring body 110, thereby improving reliability. The type of fixings may be selected according to actual conditions. For example, adhesive may be used to adhere the electric heating tape to the middle section of the air guide ring body 110 near the connection end, and the adhesiveness may be used to keep the electric heating tape in contact with the middle section, thereby improving reliability. Adhesive with good high and low temperature resistance and waterproof properties shall be selected to ensure adhesive bonding reliability. Alternatively, a through hole may be provided on the electric heating tape, and a threaded hole may be provided along the radial direction of the middle section. The position of the through hole corresponds to the position of the threaded hole. A bolt may be passed through the through hole and screwed into the threaded hole to fix the electric heating tape to the middle section, thereby facilitating the disassembly and assembly of the electric heating tape. It is also important to note that the bolts must be made of a material with good thermal expansion and contraction resistance. This prevents the bolts from expanding and interfering with the threaded connection in the threaded holes due to excessively high temperatures near the panel 210 of the air guide ring 100 when the air conditioner is in cooling mode. Furthermore, when the air conditioner is in heating mode, the bolts from contracting and interfering with the threaded connection in the threaded holes due to excessively low temperatures near the panel 210 of the air guide ring 100. This improves reliability. Alternatively, the electric heating belt can be equipped with a buckle, and a buckle position can be provided in the middle section, into which the buckle can be snapped.

[0048] In some examples, a mounting groove is opened on the circumference of the air guide ring body 110 , and the electric heating belt is disposed in the mounting groove.

[0049] It is understood that a mounting groove can be provided radially along the middle section of the air guide ring body 110, near the connection end. The electric heating belt can be placed in the mounting groove. The mounting groove restricts the axial freedom of the electric heating belt along the air guide ring body 110, reducing its movement and improving stability. The radial dimension of the electric heating belt protruding from the middle section can also be further reduced, preventing it from protruding from the air guide ring body 110 and interfering with other components, thereby ensuring the normal operation of the air conditioner outdoor unit 300.

[0050] It should be noted that the electric heating belt can be fixed in the installation groove by a fixing member, for example, the electric heating belt is adhered to the installation groove by adhesive, or the electric heating belt is fixed in the installation groove by bolts.

[0051] For example, the depth of the mounting groove can be greater than or equal to the thickness of the electric heating tape, so that the electric heating tape does not protrude from the notch of the mounting groove after being placed in the mounting groove. The width of the mounting groove can be slightly larger than the width of the electric heating tape, for example, the width of the mounting groove is 1mm to 2mm larger than the width of the electric heating tape, so as to facilitate the removal and installation of the electric heating tape while ensuring the effect of limiting the freedom of the electric heating tape along the axial direction of the air guide ring body 110.

[0052] In some examples, the electric heating belt includes a plurality of heating segments, wherein when the air guide ring body 110 is in an installed state, the heating segments are arranged on the side and / or bottom of the air guide ring body 110 .

[0053] It is understandable that the electric heating belt can be provided with a plurality of independent heating sections. Since the air conditioner outdoor unit 300 is in the working position, the air guide ring 100 is in a vertically placed state. Rainwater and condensed liquid hanging on the inner wall of the air guide ring 100 will slide down due to gravity. Therefore, the lower half of the air guide ring 100 is more likely to freeze than the upper half. Therefore, a plurality of heating sections can be set at the ice-prone parts of the air guide ring body 110 to quickly remove the ice layer in a targeted manner and prevent the air guide ring body 110 from freezing. Therefore, the heating sections are set on the left and right sides of the air guide ring body 110 and / or the bottom of the air guide ring body 110. Specifically, when the air guide ring 100 is in an installed state and placed vertically, the angle directly below the air guide ring 100 is set to 0°, and the heating sections need to cover at least the positions of 0° and ±90°.

[0054] It is understood that multiple heating segments can be arranged in series to simultaneously heat multiple locations on the air deflector body 110. Alternatively, multiple heating segments can be arranged in parallel to activate the heating segments corresponding to the ice layer locations on the air deflector body 110 to perform targeted deicing operations.

[0055] In some examples, the air guide ring 100 further includes: a controller electrically connected to the electric heating belt, for controlling the operation of the electric heating belt according to the icing condition of the air guide ring body 110 .

[0056] It is understood that the air guide ring 100 may also be provided with a controller. Specifically, the controller may be electrically connected to the electric heating belt. The controller controls the operation of the electric heating belt based on the ice condition of the air guide ring 100. For example, a temperature detector may be provided. If the temperature of the air guide ring 100 near the panel 210 is detected to be less than or equal to a preset temperature, the controller activates the electric heating belt to heat the air guide ring 100 to increase its temperature, thereby melting the ice layer on the air guide ring 100 and preventing ice formation. Alternatively, both a temperature detector and a humidity detector may be provided. To accommodate cold and high-humidity environments such as freezing rain, the temperature and humidity of the environment near the panel 210 of the air guide ring 100 may be detected simultaneously. If the humidity near the panel 210 of the air guide ring 100 is detected to be greater than or equal to a preset humidity, it indicates that the air conditioner outdoor unit 300 is in a high-humidity environment, such as rain. The temperature of the air guide ring 100 near the panel 210 is continuously monitored to determine the ambient temperature of the air conditioner outdoor unit 300. If the temperature of the air guide ring 100 near the panel 210 is detected to be less than or equal to the preset temperature, it indicates that the air conditioner outdoor unit 300 may be in a cold environment such as freezing rain. The controller activates the electric heating belt to heat the air guide ring 100 to increase the temperature, thereby melting the ice layer on the air guide ring 100 and preventing the air guide ring 100 from freezing. Or if the user observes with the naked eye that the ice layer on the air guide ring 100 is thick and there is a risk of affecting the rotation of the fan blades of the air conditioner outdoor unit 300, causing abnormal noise or even damage to the blades, the controller can be manually operated to activate the electric heating belt to heat the air conditioner outdoor unit 300 to melt the ice layer, thereby improving the protection of the blades, ensuring that the blades can operate continuously and stably, and improving the working reliability of the air conditioner outdoor unit 300.

[0057] like Figure 4 As shown, according to the second embodiment of the present application, an air conditioner housing 200 is proposed, comprising: an air guide ring 100 as described in any one of the above technical solutions; a panel 210, and the connection end of the above air guide ring 100 is connected to the back side of the above panel 210.

[0058] It is understandable that the air conditioner housing 200 may be provided with the above-mentioned air guide ring 100 and panel 210. Since the air conditioner housing 200 has the air guide ring 100 described in any one of the above technical solutions, it has all the beneficial effects of the air guide ring 100, which will not be repeated here. The air conditioner housing 200 may also be provided with side panels, a top plate and a back plate. The panel 210, the side panels, the top plate and the back plate can form a housing body after assembly, and a storage space can be formed in the housing body to accommodate parts. The panel 210 may be provided with an air outlet, which is connected to the air guide ring 100, and the air flow in the storage space is guided to the air outlet through the air guide ring 100 to ensure smooth air flow. The connection end of the air guide ring 100 may be provided on the back side of the panel 210.

[0059] For example, a grille may be provided at the air outlet to reduce the amount of foreign matter in the external environment that enters the accommodation space through the air outlet, thereby improving the protection of components.

[0060] In some examples, such as Figure 3 As shown, the panel 210 is provided with a drainage groove 211 , and the drainage groove 211 is disposed on the circumference of the air guide ring 100 .

[0061] It is understood that the panel 210 may be provided with a drainage groove 211. The shape of the drainage groove 211 matches the shape of the air guide ring 100, both being circular. The inner diameter of the drainage groove 211 is larger than the outer diameter of the air guide ring 100, allowing the drainage groove 211 to be positioned around the air guide ring 100. When the air conditioner outdoor unit 300 is exposed to rain, some rainwater will flow off the panel 210 through the drainage groove 211, reducing the amount of rainwater that accumulates on the air guide ring 100 and reducing the thickness of ice. Furthermore, if ice forms near the air guide ring 100, the heater 120 can be activated to heat the air guide ring 100, raising its temperature and melting the ice. The resulting melted water can then flow away from the panel 210 under the guidance of the drainage groove 211, reducing water accumulation on the air guide ring 100, further improving the de-icing effect, reducing the risk of re-freezing, and enhancing reliability.

[0062] like Figure 5 As shown, according to the third embodiment of the present application, an air-conditioning outdoor unit 300 is proposed, comprising: an air-conditioning housing 200 as described in any one of the above technical solutions; a fan assembly 310, arranged in the above air-conditioning housing 200; and a compressor, arranged in the above air-conditioning housing 200.

[0063] It will be appreciated that the outdoor air conditioner unit 300 may be equipped with the aforementioned air conditioner housing 200, fan assembly 310, compressor, and heat exchanger. Since the outdoor air conditioner unit 300 includes the air conditioner housing 200 described in any of the above technical solutions, it possesses all the benefits of the air conditioner housing 200 and will not be further elaborated here. The fan assembly 310 and compressor may be installed within the air conditioner housing 200. The fan assembly 310 may be equipped with a motor 311 and an impeller 312. The motor 311 may be mounted on a motor 311 bracket to provide a reliable operating environment for the motor 311. The impeller 312 is connected to the output shaft of the motor 311. The motor 311 drives the impeller 312 to rotate, causing the blades to drive airflow toward the air guide ring 100. The fan assembly 310 draws outdoor air into the air conditioner housing 200 through the air inlet, where it undergoes heat exchange with the medium in the compressor, changing the medium's form and ensuring continuous and stable heat exchange with the indoor air to adjust the indoor ambient temperature. The gas in the air conditioner housing 200 after heat exchange with the medium can be blown out of the air outlet under the action of the fan assembly 310.
