Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to a cabinet-type air conditioner indoor unit. Background Technology

[0002] An air conditioner, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air inside a building or structure.

[0003] Currently, more and more people are choosing to install air conditioners indoors to regulate the temperature of the indoor air. Floor-standing air conditioners are one type of air conditioner, and they offer significant advantages in temperature control and comfort enhancement in large spaces due to their large air volume, wide coverage, quiet operation, and rich additional functions.

[0004] In the prior art, the display panel of the indoor unit of the cabinet air conditioner has a touch function. Users can select the operating mode of the indoor unit by touching the display panel. When the indoor unit of the cabinet air conditioner blows air downwards, the air will blow directly onto the display panel, causing condensation on the display panel, which in turn causes the touch function to be insensitive or unresponsive. Utility Model Content

[0005] This application discloses a cabinet-type air conditioner indoor unit that can prevent the air conditioning air from the air outlet from blowing towards the junction and avoid condensation on the display panel.

[0006] To achieve the above objectives, some embodiments of this application provide a cabinet-type air conditioner indoor unit, comprising: a housing, the housing including: a front panel having an air outlet; an air outlet grille disposed at the air outlet; an air guide plate oscillatingly disposed at the air outlet grille to change the air outlet direction; a panel bracket disposed on the front panel and located below the front side of the air outlet, the panel bracket including: a front surface of the bracket facing the front side of the housing; an upper surface of the bracket connected above the front surface of the bracket and forming a junction with the front surface of the bracket; a display panel disposed on the front surface of the bracket; and a windbreak structure disposed on the upper surface of the bracket and located on the air outlet path between the air outlet and the junction, to prevent the air conditioning air blown from the air outlet from blowing towards the junction.

[0007] In related technologies, when air conditioning air blows out from the air outlet along the air path between the air outlet and the junction, the air conditioning air blows directly towards the junction of the front surface and the upper surface of the bracket. The area near the junction is filled with hot and humid indoor air. When the indoor unit of the cabinet air conditioner is running in cooling mode, the air conditioning air blown out is cold air. The cold air and the hot and humid indoor air meet near the junction. When the surface temperature of the junction is lower than the dew point temperature of the air, condensation will occur at the junction. The condensate on the junction will flow onto the display panel, causing the user to experience touch insensitivity or unresponsiveness when touching the display panel, thus affecting the user experience.

[0008] In this embodiment, the wind-blocking structure on the upper surface of the bracket is located on the air outlet path between the air outlet and the junction. When the air conditioning air blown from the air outlet flows along the air outlet path between the air outlet and the junction, the air conditioning air is blocked by the wind-blocking structure, thus preventing the air conditioning air from blowing onto the junction. When the air conditioning air is cold, it cannot blow onto the junction, meaning it will not mix with the warm air near the junction. This ensures that the surface temperature of the junction will not fall below the dew point temperature of the air, preventing condensation at the junction. Consequently, it ensures that there is no condensation on the surface of the display panel, guaranteeing the touch sensitivity and timely response when the user touches the display panel, thus ensuring a good user experience.

[0009] In some embodiments of this application, the windbreak structure includes: a boss disposed on the upper surface of the bracket, the boss including: a windward wall extending along the front-rear direction of the housing; a connecting wall connecting the windward wall and the upper surface of the bracket; and a gap between the connecting wall and the junction in the front-rear direction of the housing.

[0010] Thus, when the air conditioning air blown out of the air outlet blows out along the air outlet path between the air outlet and the junction, the air conditioning air will blow directly towards the junction of the windward wall and the connecting wall, causing the air conditioning air to be blocked by the junction of the windward wall and the connecting wall, forcing the air conditioning air to change its air outlet direction, so that the air conditioning air will not blow towards the junction between the front surface of the bracket and the upper surface of the bracket.

[0011] Furthermore, if there is no gap between the connecting wall and the junction in the front-rear direction of the casing, meaning the connecting wall and the front surface of the bracket are coplanar, then if condensation occurs at the connection between the windward wall and the connecting wall, the condensate adhering to the connecting wall will flow along the connecting wall to the display panel on the front surface of the bracket, resulting in poor sensitivity of the user's touch display panel. In this embodiment, however, there is a gap between the connecting wall and the junction in the front-rear direction of the casing. This prevents condensation from occurring at the connection between the windward wall and the connecting wall, and prevents the condensate from flowing along the connecting wall to the display panel. This effectively blocks the air conditioning air from blowing towards the junction while keeping the surface of the display panel dry.

[0012] In some embodiments of this application, the height H of the connecting wall in the vertical direction is greater than the width L1 of the gap in the front-rear direction of the housing.

[0013] Therefore, setting the vertical height H of the connecting wall to be greater than the front-to-back width L1 of the gap in the casing means that the vertical dimension of the supporting windward wall is also correspondingly larger. This makes the overall effective interception surface of the boss higher, enabling it to more effectively intercept the air conditioning air flowing along the air outlet path between the air outlet and the junction. The larger vertical dimension of the connecting wall ensures that the junction is covered by a protected area, preventing air conditioning air from blowing towards the junction.

[0014] In some embodiments of this application, the end of the windward wall away from the connecting wall is connected to the air outlet grille.

[0015] In this way, the windward wall, connecting wall, upper surface of the support, and front surface of the support together form a continuous and closed wall. This barrier isolates the downward airflow from the air outlet from the junction area of ​​the panel support, preventing cold air from directly washing over the junction and thus fundamentally eliminating the direct cause of condensation at the junction.

[0016] Furthermore, one end of the windward wall is fixed to the air outlet grille, while the other end is fixed to the upper surface of the panel bracket via a connecting wall. This two-point fixing method enhances the overall rigidity and stability of the boss, avoiding the risk of vibration, deformation, or even damage to the boss when subjected to long-term airflow impact or potential external collisions, thus improving structural reliability and service life.

[0017] In some embodiments of this application, the height H of the connecting wall is 5mm to 35mm in the vertical direction; and / or, the width L1 of the gap is 2mm to 30mm in the front-rear direction of the housing.

[0018] Thus, by setting the vertical height H of the connecting wall to be 5mm to 30mm, the overall height of the boss is ensured so that the air conditioning air on the air outlet path between the air outlet and the junction can be blocked by the boss and will not blow to the junction. At the same time, the boss will not block the air outlet too much, thus ensuring the air volume of the air outlet.

[0019] Furthermore, by setting the gap width L1 in the front-rear direction of the casing to be 2mm to 30mm, it means that the distance between the connecting wall and the front surface of the bracket is appropriate. This ensures that the air conditioning air blowing to the connection between the connecting wall and the windward wall will not flow along the connecting wall to the junction. It also ensures that the boss is located on the air outlet path between the air outlet and the junction without increasing the vertical height H of the connecting wall too much, thus ensuring that the air conditioning air will not blow towards the junction and ensuring the anti-condensation effect.

[0020] In some embodiments of this application, the width L2 of the windward wall in the front-rear direction of the housing is 5mm to 30mm.

[0021] In this way, by setting the width L2 of the windward wall in the front-to-back direction of the casing to 5mm to 30mm, the width of the windward wall is within a suitable range, which not only ensures its own structural strength and enables it to effectively block the wind, but also avoids the overall aesthetics and harmony of the product being damaged due to the windward wall being too wide in the front-to-back direction of the casing.

[0022] In some embodiments of this application, the upper surface of the bracket is inclined, and in the vertical direction, the junction is higher than the end of the upper surface of the bracket that connects to the connecting wall.

[0023] Thus, by setting the upper surface of the bracket to be inclined, when condensation on the connecting wall drips onto the upper surface of the bracket, the condensation can flow along the upper surface of the bracket toward the end connected to the connecting wall. The condensation naturally flows away from the junction and the display panel along the inclined upper surface of the bracket, and is eventually guided to the junction of the connecting wall and the upper surface of the bracket, thereby eliminating any possibility of liquid flowing back or dripping onto the display panel below.

[0024] In some embodiments of this application, the angle between the upper surface of the bracket and the front-rear direction of the housing is α, where α satisfies: 0°<α≤5°.

[0025] Thus, by setting the angle α between the upper surface of the bracket and the front-rear direction of the casing to 0°<α≤5°, it is ensured that the upper surface of the bracket can guide condensation to the junction between the upper surface of the bracket and the connecting wall, while avoiding interference with other components caused by excessive tilting of the upper surface of the bracket. Furthermore, a slight tilt angle of less than 5° is almost imperceptible to the user, and the upper surface of the bracket still maintains a near-horizontal, simple, and stable appearance, enhancing the premium feel of the product.

[0026] In some embodiments of this application, a plurality of drainage holes are provided at the junction of the upper surface of the bracket and the connecting wall. The plurality of drainage holes are spaced apart along the left and right direction of the housing. The plurality of drainage holes are used to discharge condensate on the upper surface of the bracket to the inner wall of the front panel.

[0027] Thus, in this embodiment, by opening multiple drainage holes at the junction of the upper surface of the bracket and the connecting wall, the condensate collected at the junction of the connecting wall and the upper surface of the bracket is drained, ensuring that the condensate does not accumulate and overflow onto the display panel.

[0028] In some embodiments of this application, the indoor unit of the cabinet air conditioner further includes:

[0029] An air guide frame is provided on the side of the air outlet grille facing the outside of the housing. The air guide frame surrounds the air outlet to form an air outlet channel. The panel bracket is located inside the air outlet channel. The front surface of the bracket is flush with the front surface of the air guide frame or located behind the front surface of the air guide frame.

[0030] In this way, the front surface of the panel bracket is flush with or located behind the front surface of the air guide frame, achieving a seamless visual connection and high degree of integration. From the user's perspective, the display panel appears to be naturally "embedded" in the outline of the air outlet channel, rather than an abrupt, additional, independent component, enhancing the product's premium feel, overall aesthetics, and design appeal, in line with the modern home appliance design trend of simplicity and integration.

[0057] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0058] As an important branch of home appliances, cabinet air conditioner indoor units have significant advantages in temperature regulation and comfort improvement in large spaces due to their large air volume, wide coverage, quiet operation, and rich additional functions.

[0059] In related technologies, cabinet-type air conditioner indoor units typically have air outlets on the front panel, and below the air outlets on the front panel is a panel bracket for mounting the display panel. When the air outlets of the cabinet-type air conditioner indoor unit blow downwards, the air will blow onto the junction of the front and upper surfaces of the panel bracket. When the air is cold, the cold air will mix with the warm and humid indoor air, causing condensation at the junction. The condensate at the junction will flow onto the display panel on the front surface of the bracket, causing touch sensitivity or unresponsiveness when the user touches the display panel, affecting the user experience.

[0060] Based on this, this application provides a cabinet-type air conditioner indoor unit that can prevent air conditioning air from blowing towards the junction of the front surface and the upper surface of the panel bracket, thus avoiding condensation problems at the junction.

[0061] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0062] Please see Figure 1This application provides a cabinet-type air conditioner indoor unit 100, which includes a casing 1. The casing 1 houses various functional components of the cabinet-type air conditioner indoor unit 100, such as a fan and a heat exchanger. The heat exchanger is used to exchange heat with the airflow flowing into the casing 1. The heat exchanger is a heat exchanger that utilizes the characteristic that liquid low-temperature refrigerant is easy to evaporate under low pressure. By absorbing the heat of the cooled medium, it lowers the temperature of the surrounding air, thereby achieving a cooling effect. The cooled air after passing through the heat exchanger is sent back to the room through the air supply system, providing a comfortable indoor environment. Especially in the hot summer, the cooling effect of the heat exchanger can significantly reduce the indoor temperature and improve people's living comfort. The fan is used to introduce airflow into the casing through the air inlet, and after heat exchange by the heat exchanger, it is sent into the room. The fan can introduce airflow into the interior of the casing, so that after heat exchange by the heat exchanger, the airflow is sent back to the room under the action of the fan.

[0063] It should be noted that the fan in this embodiment can be a cross-flow fan or other types of fans, and this embodiment does not specifically limit it.

[0064] The housing 1 includes a front panel 11, and the front panel 11 is provided with an air outlet 11a. The air outlet 11a is the part that connects the indoor unit 100 of the cabinet air conditioner to the room. After heat exchange by the heat exchanger, the airflow is sent into the room through the air outlet 11a under the action of the fan.

[0065] See Figures 2 to 4 The indoor unit 100 of the cabinet air conditioner also includes an air outlet grille 2, which is set at the air outlet 11a. As a decorative piece set at the air outlet 11a, the air outlet grille 2 not only ensures the appearance of the air outlet 11a, but also disperses the air blown out of the air outlet 11a to achieve a soft breeze.

[0066] In this embodiment, the air outlet grille 2 can be rotated or fixedly installed at the air outlet 11a. This embodiment does not specifically limit this.

[0067] like Figure 4 As shown, the indoor unit 100 of the cabinet air conditioner also includes an air guide plate 3, which is swayed on the air outlet grille 2 to change the air outlet direction of the air outlet 11a.

[0068] It should be noted that there are multiple air guide plates 3 in this embodiment, that is, there are two, three, four or more air guide plates 3. This embodiment does not limit this.

[0069] When the air outlet grille 2 can rotate, the rotation axis of the air outlet grille 2 coincides with the axis of the air outlet 11a. During the rotation of the air outlet grille 2, the air can be delivered in all directions through the swing of the air guide plate 3.

[0070] Combination Figure 1 and Figure 5 The indoor unit 100 of the cabinet air conditioner also includes a panel bracket 4, which is located on the front panel 11 and below the front side of the air outlet 11a.

[0071] The panel bracket 4 includes a front surface 41 facing the front of the housing 1.

[0072] The panel bracket 4 also includes an upper bracket surface 42, which is connected above the front bracket surface 41 and forms a junction 43 with the front bracket surface 41.

[0073] The indoor unit 100 of the cabinet air conditioner also includes a display panel 5, which is disposed on the front surface 41 of the bracket.

[0074] It should be noted that the display panel 5 in this embodiment not only has a display function, but also a touch function, that is, the user can control the operating mode, air outlet direction or other functions of the cabinet air conditioner indoor unit 100 by touching the display panel 5.

[0075] Combination Figure 1 and Figure 6 The indoor unit 100 of the cabinet air conditioner also includes a wind deflector structure 6, which is disposed on the upper surface 42 of the bracket and located in the air outlet path between the air outlet 11a and the junction 43 (e.g., Figure 8 (As shown by the dotted arrow in the image) to prevent the air conditioning air blown out of the air outlet 11a from blowing towards the junction 43.

[0076] In related technologies, when the air conditioner blows out from the air outlet 11a along the air outlet path between the air outlet 11a and the junction 43, the air conditioner air will blow directly towards the junction 43 of the front surface 41 and the upper surface 42 of the bracket. The area near the junction 43 is filled with hot and humid indoor air. When the indoor unit 100 of the cabinet air conditioner is running in cooling mode, the air conditioner air blown out is cold air. The cold air and the hot and humid indoor air meet near the junction 43. When the surface temperature of the junction 43 is lower than the dew point temperature of the air, condensation will occur on the junction 43. The condensate on the junction 43 will flow onto the display panel 5, causing the user to experience touch insensitivity or unresponsiveness when touching the display panel 5, affecting the user experience.

[0077] In this embodiment, the wind-blocking structure 6, located on the upper surface 42 of the bracket, lies on the air outlet path between the air outlet 11a and the junction 43. When the air conditioning air blown from the air outlet 11a flows along the air outlet path between the air outlet 11a and the junction 43, the air conditioning air is blocked by the wind-blocking structure 6, preventing it from blowing onto the junction 43. When the air conditioning air is cold, it cannot reach the junction 43, meaning it will not mix with the hot air near the junction 43. This ensures that the surface temperature of the junction 43 does not fall below the dew point temperature of the air, preventing condensation at the junction 43. Consequently, it ensures that there is no condensation on the surface of the display panel 5, guaranteeing the touch sensitivity and timely response when the user touches the display panel 5, thus ensuring a good user experience.

[0078] For example, when the indoor unit 100 of the cabinet air conditioner is running in cooling mode, the air blown out of the air outlet 11a is low-temperature cold air, while the indoor ambient air where the indoor unit 100 is located is usually warm and humid air. If the cold air blows directly onto the junction 43 of the panel bracket 4 without obstruction, the surface temperature of the junction 43 will drop sharply. When the surface temperature here is lower than the dew point temperature of the indoor air, water vapor in the air will condense into water droplets on the surface of the junction 43, i.e., condensation will occur. The wind deflector structure 6 effectively destroys the two necessary conditions for condensation by blocking the direct blowing of cold air: 1. It avoids the junction 43 from being directly washed by a large amount of cold air, causing its temperature to drop too low; 2. It reduces the violent airflow at the junction 43, making its local ambient temperature closer to room temperature, making it difficult to reach the dew point temperature. Therefore, it fundamentally prevents condensation at the junction 43. This prevents condensation from forming, thus completely avoiding the risk of condensation flowing down the front surface 41 of the bracket onto the display panel 5 due to gravity. Maintaining the dryness and cleanliness of the display panel 5 ensures consistently sensitive and reliable touch operation, greatly enhancing the user experience and reliability of the product.

[0079] It should be noted that the windproof structure 6 can be a windproof plate or other independent components set on the upper surface 42 of the bracket. This embodiment does not specifically limit it.

[0080] In some embodiments, combined with Figure 7 and Figure 8 The windproof structure 6 includes a boss 61, which is disposed on the upper surface 42 of the bracket. The boss 61 includes a windward wall 611, which extends along the front and rear direction of the housing 1.

[0081] The boss 61 also includes a connecting wall 612, which connects the windward wall 611 and the upper surface 42 of the bracket. In the front-rear direction of the housing 1, there is a gap M between the connecting wall 612 and the junction 43.

[0082] In other words, the windbreak structure 6 is a boss 61 composed of a windward wall 611 and a connecting wall 612.

[0083] It should be noted that the front-to-back direction of housing 1 is... Figure 7 or Figure 8 The direction from left to right or from right to left.

[0084] Since the windbreak structure 6 is located on the air outlet path between the air outlet 11a and the junction 43, that is, the boss 61 is located on the air outlet path between the air outlet 11a and the junction 43. When the air conditioning air blown out of the air outlet 11a blows out along the air outlet path between the air outlet 11a and the junction 43, the air conditioning air will blow directly towards the connection between the windward wall 611 and the connecting wall 612, causing the air conditioning air to be blocked by the connection between the windward wall 611 and the connecting wall 612, forcing the air conditioning air to change its air outlet direction, so that the air conditioning air will not blow towards the junction 43 between the front surface 41 of the bracket and the upper surface 42 of the bracket.

[0085] Furthermore, if there is no gap M between the connecting wall 612 and the junction 43 in the front-rear direction of the housing 1, that is, the connecting wall 612 and the front surface 41 of the bracket are coplanar, then if condensation occurs at the connection between the windward wall 611 and the connecting wall 612, the condensate adhering to the connecting wall 612 will flow along the connecting wall 612 to the display panel 5 on the front surface 41 of the bracket, resulting in poor sensitivity of the user's touch control of the display panel 5. In this embodiment, however, there is a gap M between the connecting wall 612 and the junction 43 in the front-rear direction of the housing 1. This prevents condensation from occurring at the connection between the windward wall 611 and the connecting wall 612, thus preventing the condensate from flowing along the connecting wall 612 to the display panel 5. This not only blocks the air conditioning air from blowing towards the junction 43 but also keeps the surface of the display panel 5 dry.

[0086] It should be noted that the shape of the connecting wall 612 can be an inclined wall (similar to the side of a trapezoidal frustum), a vertical wall, or an arc transition wall, as long as the junction 43 and the connecting wall 612 have a gap M in the front-rear direction of the housing 1. This embodiment does not make specific limitations on this.

[0087] It should be noted that the boss 61 and the upper surface 42 of the panel bracket 4 can be integrally injection molded to ensure structural strength and assembly accuracy. Of course, it can also be fixed to the upper surface 42 of the bracket as an independent component by welding or fasteners. This embodiment does not make specific limitations on this.

[0088] In some embodiments, such as Figure 8As shown, the vertical height H of the connecting wall 612 is greater than the width L1 of the gap M in the front-rear direction of the housing 1. The relationship between the vertical height H of the connecting wall 612 and the width L1 of the gap M in the front-rear direction of the housing 1 is related to whether the boss 61 can block the wind.

[0089] If the vertical height H of the connecting wall 612 is less than the width L1 of the gap M in the front-rear direction of the housing 1, it means that the vertical dimension of the connecting wall 612 is small, resulting in a lower effective interception surface of the boss 61 against the air conditioning wind in the vertical direction, thus failing to ensure that the boss 61 can block the air conditioning wind from blowing towards the junction 43.

[0090] If the vertical height H of the connecting wall 612 is equal to the width L1 of the gap M in the front-rear direction of the casing 1, when the air conditioning air flows along the air outlet 11a and the junction 43, the air conditioning air will just pass over the connection between the windward wall 611 and the connecting wall 612 and blow towards the junction 43, causing the junction 43 to still have condensation problems.

[0091] Therefore, in this embodiment, the vertical height H of the connecting wall 612 is greater than the width L1 of the gap M in the front-rear direction of the housing 1, meaning that the vertical dimension of the windward wall 611 it supports is also correspondingly larger. This makes the overall effective interception surface of the boss 61 higher, enabling it to more effectively intercept the air conditioning air flowing along the air outlet path between the air outlet 11a and the junction 43. The larger vertical dimension of the connecting wall 612 ensures that the junction 43 is covered by a protected area, preventing the air conditioning air from blowing towards the junction 43.

[0092] In some embodiments, the end of the windward wall 611 away from the connecting wall 612 is connected to the air outlet grille 2.

[0093] In other words, the end of the windward wall 611 furthest from the connecting wall 612 is connected to the air outlet grille 2, while the end closest to the connecting wall 612 is connected to the upper surface 42 of the bracket via the connecting wall 612. This makes the windward wall 611, the connecting wall 612, the upper surface 42 of the bracket, and the front surface 41 of the bracket together form a continuous and closed wall. This barrier isolates the downward airflow from the air outlet 11a from the junction 43 area of ​​the panel bracket 4, preventing cold air from directly washing over the junction 43, thus fundamentally eliminating the direct cause of condensation (direct cold air blowing) at the junction 43.

[0094] Furthermore, one end of the windward wall 611 is fixed to the air outlet grille 2, and the other end is fixed to the upper surface 42 of the panel bracket 4 via the connecting wall 612. This two-point fixing method enhances the overall rigidity and stability of the boss 61, avoiding the risk of vibration, deformation or even damage to the boss 61 (especially the higher boss 61) when subjected to long-term airflow impact or possible external collisions, thus improving structural reliability and service life.

[0095] In some embodiments, such as Figure 8 As shown, the height H of the connecting wall 612 in the vertical direction is 5mm to 30mm. The height H of the connecting wall 612 determines the windproof area of ​​the boss 61.

[0096] If the height H of the connecting wall 612 is less than 5mm, the boss 61 is too low overall, and the effective area of ​​the windbreak barrier it forms is too small. It is difficult to effectively intercept the air conditioning air on the air outlet path between the air outlet 11a and the junction 43. The air conditioning air is easy to blow to the junction 43, causing the anti-condensation effect to fail.

[0097] If the height H of the connecting wall 612 is greater than 30mm, the boss 61 will become obtrusive and tall. This will not only occupy too much space above the panel bracket 4 and below the air outlet 11a, but will also excessively block the air outlet 11a, resulting in a reduction in the air volume of the air outlet 11a.

[0098] Therefore, in this embodiment, the vertical height H of the connecting wall 612 is set to be 5mm to 30mm. This ensures that the overall height of the boss 61 is sufficient to prevent the air conditioning air on the air outlet path between the air outlet 11a and the junction 43 from being blocked by the boss 61 and blown to the junction 43. It also ensures that the boss 61 does not block the air outlet 11a too much, thus ensuring the air volume of the air outlet 11a.

[0099] It should be noted that the vertical height H of the connecting wall 612 can be 5mm, 10mm, 13mm, 15mm, 20mm, 25mm, 30mm or 35mm, and this embodiment does not make a specific limitation on it.

[0100] For example, in the vertical direction, the height H of the connecting wall 612 is 13mm. At this time, it can ensure that the height of the boss 61 can block the air conditioning air along the air outlet 11a and the junction 43 from blowing towards the junction, and can also make the air outlet 11a have a larger air volume.

[0101] In some embodiments, such as Figure 8 As shown, in the front-rear direction of the housing 1, the width L1 of the gap M is 2mm to 30mm.

[0102] The width L1 of the gap M in the front-rear direction of the housing 1 is related to the distance between the connecting wall 612 and the front surface 41 of the bracket in the front-rear direction of the housing 1.

[0103] If the gap M has a width L1 of less than 2mm in the front-rear direction of the housing 1, it means that the distance between the connecting wall 612 and the front surface 41 of the bracket in the front-rear direction of the housing 1 is too close. When the air conditioning air flowing along the air outlet path between the air outlet 11a and the junction 43 blows to the connection between the connecting wall 612 and the windward wall 611, if the distance between the connecting wall 612 and the front surface 41 of the bracket in the front-rear direction of the housing 1 is too close, the air conditioning air will flow along the connecting wall 612 to the junction 43, thus causing the anti-condensation effect to fail.

[0104] If the gap M has a width L1 greater than 30mm in the front-rear direction of the housing 1, it means that the distance between the connecting wall 612 and the front surface 41 of the bracket in the front-rear direction of the housing 1 is too far. In this case, it is necessary to increase the vertical height H of the connecting wall 612 to ensure that the height of the boss 61 is located on the air outlet path between the air outlet 11a and the junction 43. Otherwise, it cannot be guaranteed that the boss 61 is located on the air outlet path between the air outlet 11a and the junction 43, and it cannot be guaranteed that the boss 61 can effectively block the air conditioning air from blowing towards the junction 43.

[0105] Therefore, in this embodiment, by setting the gap M in the front-rear direction of the housing 1 with a width L1 of 2mm to 30mm, it means that the distance between the connecting wall 612 and the front surface 41 of the bracket is appropriate. This ensures that the air conditioning air blown to the connection between the connecting wall 612 and the windward wall 611 will not flow along the connecting wall 612 to the junction 43. It also ensures that the boss 61 is located on the air outlet path between the air outlet 11a and the junction 43 without increasing the vertical height H of the connecting wall 612 too much, thus ensuring that the air conditioning air will not blow towards the junction 43 and ensuring the anti-condensation effect.

[0106] It should be noted that the width L1 of the gap M in the front-rear direction of the housing 1 can be 2mm, 5mm, 10mm, 15mm, 20mm, 25mm or 30mm, and this embodiment does not make a specific limitation on it.

[0107] For example, in the front-rear direction of the housing 1, the width L1 of the gap M is 10mm. At this time, it ensures that there is a sufficient distance between the connecting wall 612 and the front surface 41 of the bracket, and ensures that the boss 61 is located on the air outlet path between the air outlet 11a and the junction 43 while minimizing the vertical height H of the connecting wall 612. This ensures both the air volume of the air outlet 11a and the anti-condensation effect.

[0108] It should be noted that in the above embodiments, the height H of the connecting wall 612 in the vertical direction is always greater than the width L1 of the gap M in the front-rear direction of the housing 1. That is, when the width L1 of the gap M in the front-rear direction of the housing 1 is 5mm, the height H of the connecting wall 612 in the vertical direction must be greater than 5mm to ensure that the boss 61 can play a windproof role.

[0109] In some embodiments, such as Figure 8 As shown, in the front-to-back direction of the housing 1, the width L2 of the windward wall 611 is 5mm to 30mm.

[0110] If the width L2 of the wind-facing wall 611 in the front-rear direction of the housing 1 is less than 5mm, it means that the wind-facing wall 611 is too thin. This will not only reduce its own structural rigidity, but may also cause vibration or deformation under continuous wind pressure, generating noise and affecting service life. Moreover, if the width of the wind-facing wall 611 is too narrow, it will increase the difficulty of the flow and cooling of the plastic melt during injection molding, making it easy to generate injection defects and reduce production yield.

[0111] If the width L2 of the windward wall 611 in the front-rear direction of the housing 1 is greater than 30mm, it means that the boss 61 will protrude excessively in the front-rear direction of the housing 1, which will increase material costs and product weight. Furthermore, an excessively wide boss will occupy too much visual space of the front panel 11, making it look very abrupt and bulky in design, thus ruining the overall aesthetics and harmony of the product.

[0112] Therefore, in this embodiment, by setting the width L2 of the windward wall 611 in the front-rear direction of the housing 1 to be 5mm to 30mm, the width of the windward wall 611 is within a suitable range, which not only ensures its own structural strength so that it can effectively block the wind, but also avoids the overall aesthetics and harmony of the product being damaged due to the windward wall 611 being too wide in the front-rear direction of the housing 1.

[0113] It should be noted that the width L2 of the windward wall 611 in the front-rear direction of the housing 1 can be 5mm, 10mm, 15mm, 20mm, 25mm or 30mm, and this embodiment does not make a specific limitation on it.

[0114] For example, in the front-rear direction of the housing 1, the width L2 of the windward wall 611 is 10mm. At this time, the height H of the connecting wall 612 in the vertical direction is 13mm, and the width L1 of the gap M in the front-rear direction of the housing 1 is 10mm, thus constructing a windproof boss with a robust structure, excellent windproof effect and aesthetics.

[0115] In some embodiments, such as Figure 9As shown, the upper surface 42 of the bracket is inclined, and in the vertical direction, the junction 43 is higher than the end of the upper surface 42 of the bracket that is connected to the connecting wall 612. In this embodiment, the upper surface 42 of the bracket is not horizontally arranged, but rather adopts an inclined layout. Specifically, the upper surface 42 of the bracket is configured such that the end near the junction 43 is higher, while the end away from the junction 43 (i.e., connected to the connecting wall 612) is lower.

[0116] When the air conditioning air blown out of the air outlet 11a flows along the air outlet path between the air outlet 11a and the junction 43, the air conditioning air will blow over the connection between the connecting wall 612 and the windward wall 611. When the air conditioning air is cold, condensation may occur at the connection between the connecting wall 612 and the windward wall 611, causing condensation water to adhere to the connecting wall 612. The condensation water may drip onto the upper surface 42 of the bracket. In this embodiment, by setting the upper surface 42 of the bracket to be inclined, when the condensation water on the connecting wall 612 drips onto the upper surface 42 of the bracket, the condensation water can flow along the upper surface 42 of the bracket towards the end connected to the connecting wall 612. The condensation water naturally flows away from the junction 43 and the display panel 5 along the inclined upper surface 42 of the bracket, and is eventually guided to the junction between the connecting wall 612 and the upper surface 42 of the bracket, thereby eliminating any possibility of liquid flowing back or dripping onto the lower display panel 5.

[0117] In some embodiments, such as Figure 9 As shown, the angle α between the upper surface 42 of the bracket and the front-rear direction of the housing 1 satisfies: 0°<α≤5°. The magnitude of the angle α between the upper surface 42 of the bracket and the front-rear direction of the housing 1 determines the degree of inclination of the upper surface 42 of the bracket.

[0118] If the angle α between the upper surface 42 of the bracket and the front-rear direction of the housing 1 is greater than 5°, although it can more effectively guide the condensate to the junction of the upper surface 42 of the bracket and the connecting wall 612, the excessive angle will occupy too much forward space inside the housing 1 and may interfere with other components arranged in the panel bracket 4.

[0119] Therefore, in this embodiment, the angle α between the upper surface 42 of the bracket and the front-rear direction of the housing 1 is set to 0° < α ≤ 5°. This ensures that the upper surface 42 of the bracket can guide condensate to the junction of the upper surface 42 of the bracket and the connecting wall 612, while also avoiding interference to other components caused by excessive tilting of the upper surface 42 of the bracket. Furthermore, a slight tilt angle of less than 5° is almost imperceptible to the user, and the upper surface 42 of the bracket still maintains a near-horizontal simplicity and stability in appearance, enhancing the premium feel of the product.

[0120] It should be noted that the angle α between the upper surface 42 of the bracket and the front-rear direction of the housing 1 can be 1°, 2°, 3°, 4° or 5°, and this embodiment does not make a specific limitation on this.

[0121] For example, the angle α between the upper surface 42 of the bracket and the front-rear direction of the housing 1 is 3°. At this time, the upper surface 42 of the bracket can ensure better water guiding performance while its visual and spatial impact is still negligible, which is a balance between function and aesthetics.

[0122] In some embodiments, such as Figure 10 As shown, a plurality of drainage holes 7 are provided at the junction of the upper surface 42 of the bracket and the connecting wall 612. The plurality of drainage holes 7 are spaced apart along the left and right directions of the housing 1. The plurality of drainage holes 7 are used to drain the condensate on the upper surface 42 of the bracket to the inner wall of the front panel 11.

[0123] It should be noted that the left and right directions of casing 1 are... Figure 6 The direction from left to right or from right to left.

[0124] If no drainage holes 7 are provided at the junction of the upper surface 42 of the bracket and the connecting wall 612, there is still a risk that condensation will overflow onto the display panel 5 as the amount of condensation collected at the junction increases. Therefore, in this embodiment, multiple drainage holes 7 are provided at the junction of the upper surface 42 of the bracket and the connecting wall 612 to drain the condensation collected at the junction of the connecting wall 612 and the upper surface 42 of the bracket, ensuring that condensation will not accumulate and overflow onto the display panel 5.

[0125] For example, when condensation collects at the junction of the upper surface 42 of the bracket and the connecting wall 612, the condensation can drain from the drain hole 7 to the inner wall of the front panel 11, thus allowing the condensation to bypass the display components installed inside the panel bracket 4 and flow along the inner wall of the front panel 11. The condensation can flow along the inner wall of the front panel 11 to the water collection tray or evaporation area at the bottom of the cabinet air conditioner indoor unit 100, and is finally treated by the condensate drainage system of the cabinet air conditioner indoor unit 100, or evaporate naturally, avoiding short circuits or corrosion of other components inside the casing 1 caused by the condensation.

[0126] It should be noted that a guide rib (not shown in the figure) is provided on the side of the drain hole 7 facing the inside of the housing 1. The guide rib guides the condensed water to the inner wall of the front panel 11 and then continues to flow along the inner wall of the front panel 11, thereby ensuring that the condensed water will not flow into the inside of the panel bracket 4 and cause a short circuit in the display components.

[0127] It should be noted that the multiple drainage holes 7 can be two, three, four, five or more, and this embodiment does not specifically limit this.

[0128] In some embodiments, combined with Figure 1 and Figure 7 The indoor unit 100 of the cabinet air conditioner also includes an air guide frame 8, which is located on the side of the air outlet grille 2 facing the outside of the casing 1. The air guide frame 8 surrounds the air outlet 11a to form an air outlet channel 8a. The panel bracket 4 is located inside the air outlet channel 8a, and the front surface 41 of the bracket is flush with the front surface 8b of the air guide frame 8, or located behind the front surface 8b of the air guide frame 8. That is to say, the panel bracket 4 is "embedded" in the air outlet channel 8a.

[0129] The front surface 41 of the panel bracket 4 is flush with or located behind the front surface 8b of the air guide frame 8, achieving a seamless visual connection and high integration. From the user's perspective, the display panel 5 appears to be naturally "embedded" in the outline of the air outlet channel 8a, rather than an abrupt, additional, independent component, enhancing the product's premium feel, overall aesthetics, and design appeal, in line with the modern trend of minimalist and integrated design in home appliances.

[0130] For example, when the front surface 41 of the panel bracket 4 is flush with the front surface 8b of the air guide frame 8, when the user observes the indoor unit 100 of the cabinet air conditioner from the front, the front surface 41 of the panel bracket 4 and the front surface 8b of the air guide frame 8 are on the same plane, making the overall appearance neater and more cohesive.

[0131] When the front surface 41 of the panel bracket 4 is located behind the front surface 8b of the air guide frame 8, when the user observes the cabinet air conditioner indoor unit 100 from the front, the front surface 41 of the panel bracket 4 and the front surface 8b of the air guide frame 8 form an interlaced three-dimensional visual effect, enhancing the high-end appearance of the cabinet air conditioner indoor unit 100.

[0132] Of course, the front surface 41 of the panel bracket 4 can also protrude from the front surface 8b of the air guide frame 8, but this embodiment does not specifically limit this.

[0133] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
