Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, such as a handle assembly for an outdoor unit and an air conditioning outdoor unit. Background Technology

[0002] Inverter air conditioners have become the mainstream in the air conditioning industry, but with the continued occurrence of high temperatures in recent years, with summer temperatures reaching 42°C or even close to 50°C across the globe, air conditioners failing to cool or experiencing reduced cooling capacity have become new complaints from users. To address these user pain points, air conditioners that maintain cooling performance even at high temperatures are a new research and development direction for air conditioning companies.

[0003] The inverter chip is a crucial component in inverter air conditioners, determining the compressor's operating frequency. A higher compressor frequency results in stronger cooling capacity in summer, but this also leads to a surge in heat generation from components on the control board. The main heat-generating components in the inverter control system include four power devices: IPM, IGBT, diodes, and a rectifier bridge, as well as inductors, reactance, capacitors, the fan IPM, and internal circuitry on the control board. With advancements in semiconductor technology, chip designs have become more compact, increasing the heat flux density of components, and miniaturizing the control board and its components. Simultaneously, the compressor compartment's ambient temperature significantly impacts the stable operation of the control components and the compressor. High temperatures can cause a sharp increase in compressor casing temperature and exhaust temperature, potentially leading to compressor shutdown due to high temperature. Therefore, the compressor compartment, inverter control system, and their components suffer from high temperatures, high heat flux density, and high power consumption, severely restricting the air conditioner's operational safety and high-temperature cooling capacity. Solving the high-temperature heat dissipation problem of the compressor compartment, inverter control system, and components is crucial for ensuring consistent high-temperature cooling performance, which is of paramount importance in the air conditioning industry.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: Currently, compressor compartments mostly adopt a closed sand-proof and waterproof design, and some air conditioners have added handles and side shell air-expelling designs. However, in the case of air-conditioning environments with a lot of sand and dust, the traditional air-expelling handle structure has poor sand-proof effect, which can easily lead to sand and dust entering the compressor compartment and can easily block the air vents. When sand and dust enter the compressor compartment, it can easily cause failure of the electrical control board and power lines.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a handle assembly for an outdoor unit and an outdoor air conditioning unit to solve the problem that when an air vent is opened in the handle of an existing outdoor air conditioning unit, sand and dust can easily enter the interior of the outdoor unit, blocking the air vent and causing power line failure of the outdoor unit.

[0008] In some embodiments, the handle assembly for the outdoor unit includes: a handle member having an air inlet, the inner cavity of the handle member including an air turbulence zone and an air intake zone; a turbulence assembly disposed in the air turbulence zone of the handle member, the turbulence assembly including a plurality of staggered turbulence plates, and an air passage gap formed between the turbulence plates and the inner wall of the handle member; and a partition plate disposed in the air intake zone of the handle member, the partition plate having an air outlet, and the partition plate forming an air duct with the inner wall of the handle member, wherein dust in the ambient temperature air introduced from the air inlet is blocked by the turbulence plates, and the ambient temperature air enters the air duct after passing through the air gap, and enters the housing of the outdoor unit through the air outlet of the partition plate.

[0009] In some alternative embodiments, the handle component includes a handle front shell, a first handle side plate disposed on one side of the handle front shell, and a second handle side plate disposed on the other side of the handle front shell, wherein the handle front shell, the first handle side plate, and the second handle side plate form a semi-enclosed inner cavity.

[0010] In some alternative embodiments, the induced draft turbulence zone and the induced draft air intake zone are arranged in a vertical direction, and the induced draft turbulence zone is located at the lower part of the induced draft air intake zone.

[0011] In some alternative embodiments, an inner baffle is provided between the air turbulence zone and the air intake zone of the handle component. The baffle is sleeved on the upper part of the inner baffle, and the inner baffle has an air intake mesh that communicates with the air duct.

[0012] In some optional embodiments, the spoiler assembly includes: a first spoiler plate disposed on the inner wall surface of the first handle side plate of the handle member; and a second spoiler plate disposed adjacent to the first spoiler plate and above the first spoiler plate, the second spoiler plate being disposed on the inner wall surface of the second handle side plate of the handle member, wherein a first air passage gap is formed between the first spoiler plate and the inner wall surface of the second handle side plate, and a second air passage gap is formed between the second spoiler plate and the inner wall surface of the first handle side plate, such that the first air passage gap and the second air passage gap are staggered.

[0013] In some alternative embodiments, the first spoiler makes an angle a1 with the horizontal direction, where a1 ≥ 0.5°.

[0014] In some alternative embodiments, a1 ≤ 30°.

[0015] In some alternative embodiments, the outdoor unit housing includes a front housing and a rear housing opposite to the front housing, and a first handle side panel is located near the rear housing, wherein an air vent is formed on the first handle side panel.

[0016] In some embodiments, the outdoor unit of the air conditioner includes a handle assembly for the outdoor unit as described above.

[0017] In some alternative embodiments, the outdoor unit of the air conditioner also includes wiring terminals, wherein a partition is provided on the outside of the wiring terminals.

[0018] The handle assembly for an outdoor unit and the air conditioner outdoor unit provided in this disclosure can achieve the following technical effects: The handle assembly for outdoor units includes a handle component, a spoiler component, and a sleeve partition.

[0019] The handle component is equipped with an air inlet, and its inner cavity includes an air-induced turbulence zone and an air-induced intake zone. A turbulence assembly is located in the air-induced turbulence zone of the handle component, comprising multiple staggered turbulence plates, with air gaps formed between the turbulence plates and the inner wall of the handle component. A baffle plate is located in the air-induced intake zone of the handle component, with an air outlet, and forms an air-induced duct with the inner wall of the handle component. Dust in the ambient temperature air introduced from the air inlet is blocked by the turbulence plates, and the ambient temperature air enters the air-induced duct after passing through the air gap, and then enters the outdoor unit's casing through the air outlet of the baffle plate.

[0020] In this way, if the ambient air introduced from the air inlet of the handle component contains impurities such as sand and dust, the impurities will be turbulent and turned by the shielding effect of the spoiler. After the sand and dust hit the spoiler, they will slow down or even stall and fall downwards by their own gravity, eventually being discharged from the handle component.

[0021] As can be seen, the handle assembly provided in this embodiment effectively prevents dust in the ambient temperature wind from entering the interior of the air conditioner outdoor unit through the air inlet of the handle, improves the heat dissipation effect of the air inlet on the electrical control module of the air conditioner outdoor unit, avoids dust clogging the air inlet, and avoids the problem of dust causing circuit failure to the power supply of the air conditioner outdoor unit.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0031] This disclosure provides a handle assembly for an outdoor unit.

[0032] The handle assembly includes a handle component 1, a spoiler component 2, and a sleeved partition 3.

[0033] The handle component 1 is provided with an air inlet 11. The inner cavity of the handle component 1 includes an air turbulence zone 101 and an air intake zone 102. A turbulence assembly 2 is disposed in the air turbulence zone 101 of the handle component 1. The turbulence assembly 2 includes multiple staggered turbulence plates, and an air passage gap is formed between the turbulence plates and the inner wall of the handle component 1. A partition 3 is disposed in the air intake zone 102 of the handle component 1. The partition 3 has an air outlet 31, and the partition 3 and the inner wall of the handle component 1 form an air duct. Among them, the dust in the normal temperature air introduced from the air inlet 11 is blocked by the turbulence plates, and the normal temperature air enters the air duct after passing through the air gap, and enters the outdoor unit housing through the air outlet 31 of the partition 3.

[0034] In existing solutions for cooling the inverter chip of an air conditioner outdoor unit, a normal temperature air intake vent 11 can be opened on the casing of the air conditioner outdoor unit to introduce normal temperature air from the outside environment to cool the heat-generating components such as the inverter chip.

[0035] However, in some dusty weather, especially in Xinjiang and Inner Mongolia, when the normal temperature air from outside the air conditioner is introduced, the dust mixed in with the air can easily enter the interior of the air conditioner through the air inlet 11, affecting the heat dissipation of heat-generating components such as the inverter chip, and may also lead to internal electrical control and circuit failures.

[0036] This disclosure provides a windproof and waterproof handle assembly that filters out impurities such as sand and dust carried in the wind during the process of introducing normal temperature air.

[0037] The handle component 1 has an air inlet 11. When the fan of the outdoor unit of the air conditioner rotates, a pressure difference is formed between the fan compartment, the compressor compartment and the external environment. Through this pressure difference, the ambient temperature air from the external environment is introduced into the compressor compartment through the air inlet 11. After the inverter chip is cooled, the air enters the fan compartment and is discharged from the air outlet 31 of the fan compartment, thus completing one air cooling cycle.

[0038] The inner cavity of the handle component 1 includes an air turbulence zone 101 and an air intake zone 102. The ambient temperature air entering through the air inlet 11 first passes through the air turbulence zone 101 for filtration, which blocks and filters impurities such as sand and dust in the ambient temperature air. The filtered clean ambient temperature air then enters the casing of the outdoor unit through the air intake zone 102.

[0039] Optionally, the induced draft turbulence zone 101 is connected to the induced draft air intake zone 102 so that the filtered room temperature air in the induced draft turbulence zone 101 can smoothly enter the induced draft air intake zone 102.

[0040] Optionally, the induced draft turbulence zone 101 and the induced draft air intake zone 102 are arranged sequentially along the intake path of the normal temperature wind, with the induced draft turbulence zone 101 located upstream of the intake path of the normal temperature wind and the induced draft air intake zone 102 located downstream of the intake path of the normal temperature wind.

[0041] Optionally, multiple air intake grilles are provided at the air inlet 11 to perform primary filtration of some sand, water and other large particulate solid impurities in the outside wind.

[0042] The airflow spoiler assembly 2 is disposed in the airflow spoiler area 101 of the handle component 1, and multiple spoilers are staggered from bottom to top along the inner surface of the handle front shell 14, such as... Figures 2 to 5 As shown.

[0043] Multiple staggered baffles can directly block dust in the air entering through the air inlet 11. Normal temperature air enters through the air inlet 11 located at the bottom of the handle's base 17. Dust mixed in with the air also enters from bottom to top. Dust not blocked by the air intake grille of the air inlet 11 enters the handle's interior and is blocked in multiple layers by the staggered baffles. The dust impacts the baffles, slowing or stalling, and is then discharged from the lower air inlet 11 under gravity. Meanwhile, the air enters the outdoor unit of the air conditioner through the air gap, thus achieving its heat dissipation effect.

[0044] The partition 3 is installed in the air intake area 102 inside the handle component 1. The normal temperature air entering from the air intake 11 of the handle component 1 first passes through the multi-level shielding of the air turbulence area 101 to filter the sand and dust. The filtered clean normal temperature air passes through the air duct formed between the partition 3 and the inner wall of the handle component 1, and enters the casing of the outdoor unit through the air outlet 31 on the partition 3, so as to exert its heat dissipation effect on the inverter module.

[0045] Optionally, a partition 3 is installed to cover the wiring terminals 5 of the outdoor unit of the air conditioner.

[0046] The partition 3 has an air outlet 31, through which clean air filtered by the turbulence component 2 enters the interior of the outdoor unit of the air conditioner.

[0047] Optionally, the partition 3 is in the shape of a boss, used to form a covering space for the terminal block 5.

[0048] like Figure 9 and Figure 10 As shown, the sleeve partition 3 includes a first partition wall 301 and a second partition wall 302. The boss-shaped sleeve partition 3 protrudes from the first partition wall 301, and an air passage gap is formed between the first partition wall 301 and the inner surface of the handle.

[0049] Optionally, the first partition wall 301 includes a partition slope near the air outlet 31, and the inner surface of the handle includes a handle slope. The partition slope and the handle slope form an inclined gap, wherein the ambient temperature air passing through the air gap is redirected through the inclined gap and enters the outdoor unit of the air conditioner from the air outlet 31 on which the partition 3 is fitted. In this way, the air intake direction of the S-shaped path is different from the air intake direction of the inclined gap, that is, the ambient temperature air is redirected. Furthermore, when the ambient temperature air passes through the inclined gap, the sand and dust that are not blocked by the turbulence component 2 further fall back under the action of gravity within the inclined gap. It can be seen that the setting of the inclined gap improves the filtration effect of sand and dust.

[0050] Optionally, the air outlet 31 with the partition 3 is set in a horizontal direction, so that the air in the inclined gap is redirected again and flows into the air outlet 31, which improves the filtration effect of sand and dust.

[0051] Optionally, the more spoilers the spoiler assembly 2 has, the better its effect in blocking sand and dust.

[0052] Optionally, the air outlet 31 of the partition 3 is located on the upper part of the partition 3. Optionally, the air outlet 31 can be a rectangular hole, and a sheet metal guardrail is provided around the air outlet 31. This can enhance the strength of the partition 3 and prevent deformation and twisting. At the same time, the folded edge of the guardrail increases the air duct depth of the air outlet 31, and the folded edge of the guardrail also has a certain function of preventing wind and sand. Optionally, the air outlet 31 can also be in the shape of a louver or similar.

[0053] Optionally, the edge of the handle component 1 and the edge of the sleeve partition 3 are sleeved and connected by a fixing structure such as screws.

[0054] Optionally, the handle component 1 includes a handle front shell 14, a first handle side plate 12 disposed on one side of the handle front shell 14, and a second handle side plate 13 disposed on the other side of the handle front shell 14, wherein the handle front shell 14, the first handle side plate 12, and the second handle side plate 13 form a semi-enclosed inner cavity.

[0055] The handle component 1 has a handle front shell 14, a first handle side plate 12, and a second handle side plate 13 forming a three-sided semi-enclosed inner cavity. When the handle component is installed on the housing of the outdoor unit of the air conditioner, the handle component 1 and the housing of the outdoor unit of the air conditioner form a complete normal temperature air intake path.

[0056] Optionally, the induced draft turbulence zone 101 and the induced draft air intake zone 102 are arranged in the vertical direction, and the induced draft turbulence zone 101 is located at the lower part of the induced draft air intake zone 102.

[0057] Along the vertical direction, the height of the induced draft turbulence zone 101 is greater than the height of the induced draft air intake zone 102. The relatively large height of the induced draft turbulence zone 101 improves the airflow volume of ambient temperature air and the filtering effect on dust in the ambient temperature air; the relatively small height of the induced draft air intake zone 102 allows clean ambient temperature air to quickly enter the casing of the outdoor unit of the air conditioner through the induced draft air intake zone 102, reducing the airflow resistance of ambient temperature air and ensuring the airflow volume and velocity of ambient temperature air entering the outdoor unit of the air conditioner.

[0058] Optionally, an inner baffle 15 is provided between the air turbulence zone 101 and the air intake zone 102 of the handle component 1. The baffle 3 is provided on the upper part of the inner baffle 15, and the inner baffle 15 has an air intake mesh 151 that communicates with the air duct.

[0059] The inner partition 15 divides the inner cavity of the handle component 1 into an airflow disturbance zone and an airflow inlet zone 102. The inner partition 15 is arranged horizontally. The air inlet mesh 151 of the inner partition 15 connects the airflow disturbance zone 101 and the airflow inlet zone 102. The inner partition 15 includes a first inner partition edge near the inner wall surface of the first handle side plate 12, a second inner partition edge near the inner wall surface of the second handle side plate 13, and a third inner partition edge near the inner wall surface of the handle front shell 14. The air inlet mesh 151 is opened along the edges of the first, second, and third inner partitions. This ensures that the opening of the air inlet mesh 151 corresponds to the air gap and the airflow duct, which facilitates the entry of air flowing out through the air gap into the airflow duct.

[0060] Optionally, the spoiler assembly 2 includes a first spoiler 21 and a second spoiler 22. The first spoiler 21 is disposed on the inner wall surface of the first handle side plate 12 of the handle member 1; the second spoiler 22 is disposed adjacent to the first spoiler 21 and above the first spoiler 21, and is disposed on the inner wall surface of the second handle side plate 13 of the handle member 1. A first air passage gap 211 is formed between the first spoiler 21 and the inner wall surface of the second handle side plate 13, and a second air passage gap 221 is formed between the second spoiler 22 and the inner wall surface of the first handle side plate 12, so that the first air passage gap 211 and the second air passage gap 221 are staggered.

[0061] The first spoiler 21 and the second spoiler 22 are arranged sequentially from bottom to top. The first handle side plate 12 is disposed on one side of the handle member 1, and the second handle side plate 13 is disposed on the other side of the handle member 1. The first spoiler 21 is disposed on the inner wall surface of the first handle side plate 12, and a first air passage gap 211 is formed between the inner wall surfaces of the first spoiler 21 and the second handle side plate 13. The second spoiler 22 is disposed on the inner wall surface of the second handle side plate 13, and a second air passage gap 221 is formed between the inner wall surface of the second spoiler 22 and the first handle side plate 12. In this way, the first air passage gap 211 and the second air passage gap 221 are arranged alternately in a vertical direction.

[0062] like Figure 8 As shown, the first spoiler 21 includes a first spoiler edge 212, a second spoiler edge 213, a third spoiler edge 214 and a fourth spoiler edge 215. The first spoiler edge 212 is fixedly disposed on the inner wall surface of the first handle side plate 12, the second spoiler edge 213 is fixedly disposed on the inner surface of the handle front shell 14, and a first air passage gap 211 is formed between the third spoiler edge 214 and the inner wall surface of the second handle side plate 13.

[0063] Similarly, the second spoiler 22 includes a fifth spoiler edge, a sixth spoiler edge, a seventh spoiler edge and an eighth spoiler edge, wherein the fifth spoiler edge is fixedly disposed on the inner wall surface of the second handle side plate 13, the sixth spoiler edge is fixedly disposed on the inner surface of the handle front shell 14, and a second air passage gap 221 is formed between the seventh spoiler edge and the inner wall surface of the first handle side plate 12.

[0064] In this way, the sand and dust brought in by the ambient temperature wind from the air intake 11 are first blocked by the first spoiler 21, thus partially blocking the sand and dust. The unblocked sand and dust then pass through the first air passage gap 211 with the ambient temperature wind and are further blocked by the second spoiler 22. Thus, the spoiler assembly 2 forms a multi-stage barrier against sand and dust, thereby improving the sand and dust blocking effect. Figure 6 As shown.

[0065] The first spoiler 21 slopes downward from the first handlebar side panel 12 toward the second handlebar side panel 13, and the second spoiler 22 slopes downward from the second handlebar side panel 13 toward the first handlebar side panel 12. Figure 6 As shown.

[0066] The first spoiler 21 and the second spoiler 22 are both inclined, and the inclination directions are different. This improves the multi-level shielding effect of the staggered first spoiler 21 and the second spoiler 22 on sand and dust.

[0067] Optionally, the first spoiler 21 makes an angle α1 with the horizontal direction, where α1 ≥ 0.5°. Figure 7As shown. The angle α1 between the first spoiler 21 and the horizontal direction can be 0.5°, 1°, 3°, 5°, 7°, 10°, 13°, 15°, 17°, 20°, 23°, 25°, 27° or 30°. Optionally, α1 ≤ 30°.

[0068] Similarly, the second spoiler 22 makes an angle α2 with the horizontal direction, where α2 ≥ 0.5°. The angle α2 between the second spoiler 22 and the horizontal direction can be 0.5°, 1°, 3°, 5°, 7°, 10°, 13°, 15°, 17°, 20°, 23°, 25°, 27°, or 30°. Optionally, α2 ≤ 30°.

[0069] Optionally, the angles between the multiple spoilers and the horizontal direction gradually decrease from bottom to top; that is, the angle α1 between the first spoiler 21 and the horizontal direction is greater than the angle α2 between the second spoiler 22 and the horizontal direction. The closer to the air inlet 11, the greater the intake velocity of the ambient temperature wind. In this embodiment, as the ambient temperature wind enters the airway, the angle between the spoilers and the horizontal direction gradually decreases. This ensures that the multiple spoilers effectively shield against sand and dust while gradually reducing the wind resistance of the spoilers to the ambient temperature wind, thereby increasing the intake volume and velocity of the ambient temperature wind at the air inlet 11.

[0070] Optionally, such as Figure 8 As shown, the length of the spoilers is along the longitudinal direction. Along the vertical direction, the length of the multiple spoilers gradually decreases, meaning that the length or area of ​​the air gaps formed by the spoilers gradually increases. In this way, while ensuring the shielding effect of the multiple spoilers on sand and dust, the airflow through the air gaps is gradually increased, thereby increasing the airflow and wind speed of the ambient temperature wind at the 11 air inlets.

[0071] Optionally, the distance between the first handle side plate 12 and the second handle side plate 13 of the handle component 1 is the handle length K, and the length of the spoiler along the length direction is K1, where 0.5K < K1 < K. This improves the spoiler's turbulence effect and ensures the air intake volume of the air inlet 11.

[0072] Optionally, along the height direction, the greater the height of the handle component 1, the greater the vertical space for placing the spoiler, the more spoilers there are, and the greater the angle between the spoiler and the horizontal direction.

[0073] Optionally, the vertical distance H1 between the first spoiler 21 and the handle bottom shell 17 is greater than or equal to 10 mm, which helps to increase the intake volume of normal temperature air at the air inlet 11. Optionally, the spoiler assembly 2 includes an upper spoiler located at the uppermost end, and the vertical distance H2 between the upper spoiler and the handle inner partition 15 is greater than or equal to 5 mm. Optionally, H1 ≥ H2.

[0074] Optionally, the first spoiler 21 is inclined downwards from the second spoiler edge 213 towards the fourth spoiler edge 215. This causes the sand and dust blocked by the first spoiler 21 to accumulate at the fourth spoiler edge 215 and fall near it. Similarly, the second spoiler 22 is inclined downwards from the sixth spoiler edge towards the eighth spoiler edge, causing the sand and dust blocked by the second spoiler 22 to accumulate at the eighth spoiler edge. This facilitates the separation of sand and dust from the filtered ambient air, improving the filtration and separation effect of the spoilers.

[0075] Optionally, the air vent 11 is formed in the handle base shell 17 of the handle component 1, such as... Figure 3 As shown.

[0076] Optionally, the outdoor unit housing includes a front housing 41 and a rear housing 42 opposite to the front housing 41, and a first handle side panel 12 is close to the rear housing 42, wherein an air vent 11 is opened on the first handle side panel 12.

[0077] Air conditioner outdoor units are usually wall-mounted. The rear shell 42 of the casing is larger than the wall, creating a gap and reducing airflow. The air inlet 11 is located on the first handle side plate 12 near the rear shell 42, which reduces the probability of air entering the casing and thus reduces the probability of sand and dust entering the outdoor unit.

[0078] When the air vent 11 is located on the side panel 12 of the first handle, such as Figure 12 As shown, at this time, the grille opened on the bottom shell 17 of the handle can serve as a pressure relief mesh 16. When the air inlet 11 is opened on the first handle side plate 12, air inflow may occur. When air inflow occurs, the pressure relief mesh 16 has a certain pressure relief effect, reducing the amount of air inflow.
