Description

Technical Field

[0001] The invention relates to the technical field of air supply structures, in particular to an air outlet component, an indoor unit and an air conditioning system. Background Art

[0002] Single-sided air outlet ceiling air conditioners are widely used in hotels, office buildings, shopping malls, apartments, villas, homes and other places with limited installation or special needs due to their downward return and downward flow mode, providing people with a comfortable and pleasant living and working environment. When a cross-flow fan is used, the air conditioning unit is generally a suction type, but its static pressure capacity is poor; when a centrifugal fan is used, the unit is generally a blowing type, with good static pressure capacity and strong air supply capacity. In kitchen air conditioning, due to the high oil smoke environment in the kitchen, the unit uses a high-efficiency filter to filter the oil smoke, which has a large resistance, and the use of a blowing type unit is more advantageous.

[0003] At the same time, the kitchen is in a high temperature and high humidity environment, and the blower-type unit with downward return and downward discharge will inevitably have condensation problems at the air outlet. Due to the inertia of the airflow itself, the airflow always flows close to the side away from the water tray at the air outlet, and the cold air distribution at the air outlet is seriously uneven during cooling. A large amount of cold air flows through the windward side of the air guide plate at the air outlet, while only a small amount of cold air flows on the leeward side. The cold air gathered on the windward side of the plate reduces the temperature of the entire air guide plate. The leeward side is in contact with the original high temperature and high humidity air in the room. The large temperature difference causes condensation problems on the air guide plate, affecting the user experience. Summary of the invention

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The kitchen is in a high temperature and high humidity environment, and the blower-type unit with downward discharge will inevitably have condensation problems at the air outlet. Due to the inertia of the airflow itself, the airflow always flows close to the side away from the water tray at the air outlet, and the cold air distribution at the air outlet is seriously uneven during cooling. A large amount of cold air flows through the windward side of the air guide plate at the air outlet, while only a small amount of cold air flows on the leeward side. The cold air gathered on the windward side of the plate reduces the temperature of the entire air guide plate. The leeward side is in contact with the original high temperature and high humidity air in the room. The large temperature difference causes condensation problems on the air guide plate, affecting the user experience.

[0043] To this end, the present application provides a Figures 1 to 8The air outlet assembly shown includes: an air outlet guide member 1, wherein an air outlet duct 11 is formed in the air outlet guide member 1, and an air outlet 12 is formed at one end of the air outlet duct 11; an anti-condensation structure 2, wherein the anti-condensation structure 2 is arranged in the air outlet duct 11, and the anti-condensation structure 2 has a windward surface; an air guide plate 3, wherein the air guide plate 3 is arranged at the air outlet 12, and the windward surface can direct the airflow in the air outlet duct 11 to the leeward side of the air guide plate 3. By setting an anti-condensation structure 2 upstream of the air guide plate 3, the airflow blown from the air guide plate 3 is guided to the leeward side of the air guide plate 3, and cold air passes through both the windward side and the leeward side of the air guide plate 3, thereby isolating the high-temperature and high-humidity air from contacting the air guide plate 3, reducing the temperature difference between the windward side and the leeward side of the air guide plate 3, and thus avoiding the occurrence of condensation problems on the air guide plate 3. At the same time, the anti-condensation structure 2 can also reduce the ability of the airflow to generate eddies in the air outlet duct 11, further improving the uniformity of the air volume distribution between the windward side and the leeward side of the air guide plate 3, making the airflow distribution at the air outlet 12 more uniform, avoiding the generation of eddy noise at the air outlet 12, and improving the user experience.

[0044] Furthermore, the windward surface is provided with a guide groove 21, and the guide groove 21 forms a guide outlet on the edge of the anti-condensation structure 2 close to the air outlet 12, and the outflow direction of the guide outlet points to the leeward side of the air guide plate 3. The guide groove 21 is used to further increase the ability of the fluid on the windward surface to move to the leeward side of the air guide plate, thereby increasing the ability to adjust the air volume on the windward side and the leeward side of the air guide plate 3, avoiding the occurrence of condensation problems, and making the airflow distribution of the air outlet 12 more uniform, avoiding the generation of eddy noise at the air outlet 12, and improving the user experience.

[0045] As an embodiment, the anti-condensation structure 2 includes a first guide portion 22 and a second guide portion 23 connected to each other, the side of the first guide portion 22 away from the air outlet 12 and the side of the second guide portion 23 away from the air outlet 12 together constitute the windward surface, and the first guide portion 22 protrudes toward the air outlet 12, and the second guide portion 23 protrudes away from the air outlet 12. At this time, the cross-sectional shape of the anti-condensation structure 2 is S-shaped, and the fluid flowing to the anti-condensation structure 2 will first contact the first guide portion 22, and then pass through the first guide portion 22. The guide part 22 is used to divert the flow, so that it can be directed to the leeward side of the air guide plate 3, reducing the impact of the fluid on the anti-condensation structure 2, and the second guide part 23 is used to reduce the flow of the fluid that is about to flow out of the anti-condensation structure 2 to the side wall of the air outlet duct 11, reduce the impact loss of the fluid, and further improve the state of the fluid flowing on the leeward side of the air guide plate 3, thereby increasing the ability to adjust the air volume on the windward side and the leeward side of the air guide plate 3, avoiding the occurrence of condensation problems, and making the airflow distribution at the air outlet 12 more uniform, avoiding the generation of eddy noise at the air outlet 12, thereby improving the user experience.

[0046] The cross-sections of the first guide part 22 and the second guide part 23 are both arc-shaped, and the relationship between the radius R1 of the first guide part 22 and the width k of the air outlet duct 11 is 1≤R1 / k≤1.3. When R1 is too large, flow separation will occur in the process of airflow flowing in the windward surface and the guide groove 21, resulting in air volume loss and uneven distribution of air volume downstream. When R1 is too small, the guiding effect of the first guide part 22 on the fluid will be reduced, and the air volume flowing to the leeward side of the air guide plate 3 will be reduced, resulting in uneven air volume on the windward side and the leeward side of the air guide plate 3, and condensation will still occur. Only when 1≤R1 / k≤1.3 can the guiding effect of the first guide part 22 on the fluid be guaranteed, and flow separation can be avoided, and the ability to adjust the air volume on the windward side and the leeward side of the air guide plate 3 can be increased to avoid the occurrence of condensation problems. The airflow distribution of the air outlet 12 is more uniform, avoiding the generation of eddy noise at the air outlet 12, and improving the user experience.

[0047] The relationship between the radius R2 of the second guide portion 23 and the width k of the air outlet duct 11 is 0.7≤R2 / k≤1. When R2 is too large, flow separation will occur in the process of the airflow flowing on the windward surface and in the guide groove 21, resulting in air volume loss and uneven air volume distribution downstream. When R2 is too small, the guiding effect of the second guide portion 23 on the fluid will be reduced, and the fluid will still impact the inner wall of the air outlet duct 11 and cause impact loss. Only when 0.7≤R2 / k≤1 can the guiding effect of the second guide portion 23 on the fluid be guaranteed, flow separation can be avoided, and impact loss can be reduced. The airflow distribution at the air outlet 12 is more uniform, and eddy noise at the air outlet 12 can be avoided, thereby improving the user experience.

[0048] In order to prevent the anti-condensation structure 2 from obstructing the fluid too much and affecting the air outlet effect of the air outlet component, an air hole is provided between two adjacent guide grooves 21. The air hole allows part of the fluid to flow directly through the anti-condensation structure 2 to ensure the air outlet effect of the air outlet component.

[0049] Specifically, the first air outlet 24 is provided on the first air guide portion 22, and the second air outlet 25 is provided on the second air guide portion 23. The first air outlet 24 and the second air outlet 25 together constitute the air hole. By respectively providing the first air outlet 24 on the first air guide portion 22 and the second air outlet 25 on the second air guide portion 23, a certain connection structure can exist between the first air outlet 24 and the second air outlet 25, thereby ensuring the structural strength of the anti-condensation structure 2.

[0050] The relationship between the projection width W1 of the first air outlet 24 on the plane where the air outlet 12 is located and the width k of the air outlet duct 11 is 0.15≤W1 / k≤0.35. W1 will affect the flow area of ​​the first air outlet 24. When W1 is too small, the flow area of ​​the first air outlet 24 is too small. At this time, the amount of fluid that can pass through the first guide part 22 is small, which will seriously affect the air outlet effect of the air outlet component. When W1 is too large, the size of the first air outlet 24 is too large, which reduces the number of guide grooves 21 and cannot reliably guide the fluid. The problem of condensation will still occur on the air guide plate 3. Only when 0.15≤W1 / k≤0.35 can the air volume of the air outlet component and the condensation of the air guide plate 3 be guaranteed at the same time, thereby ensuring the user experience of the air outlet component.

[0051] The relationship between the projection width W2 of the second air outlet 25 on the plane where the air outlet 12 is located and the width k of the air outlet duct 11 is 0.1≤W2 / k≤0.3. W2 will affect the flow area of ​​the second air outlet 25. When W2 is too small, the flow area of ​​the second air outlet 25 is too small. At this time, the amount of fluid that can pass through the second guide part 23 is small, which will seriously affect the air outlet effect of the air outlet component. When W2 is too large, the size of the second air outlet 25 is too large, which reduces the number of guide grooves 21 and cannot reliably guide the fluid. The problem of condensation will still occur on the air guide plate 3. Only when 0.1≤W2 / k≤0.3 can the air volume of the air outlet component and the condensation of the air guide plate 3 be guaranteed at the same time, thereby ensuring the user experience of the air outlet component.

[0052] The relationship between the projection width W1 of the first air outlet 24 on the plane where the air outlet 12 is located and the projection width W2 of the second air outlet 25 on the plane where the air outlet 12 is located is W1>W2. The fluid in the air outlet duct 11 will preferentially contact the first air outlet 24. Therefore, the size of the first air outlet 24 needs to be increased as much as possible to ensure the air volume of the air outlet component.

[0053] The projection length of the first air outlet 24 on the plane where the air outlet 12 is located is equal to the projection length of the second air outlet 25 on the plane where the air outlet 12 is located. Since the first air outlet 24 and the second air outlet 25 together form an air hole, and the air hole is located between the two guide grooves 21, in order to ensure the uniform distribution of the guide grooves 21, the spacing between the two guide grooves 21 is equal, and the adjacent edges of the two guide grooves 21 constitute the two opposite edges of the air hole, and the projections of these two edges on the plane where the air outlet 12 are two parallel line segments, and these two line segments are distributed along the width direction of the air outlet 12. The projection length of the first air outlet 24 on the plane where the air outlet 12 is located and the projection length of the second air outlet 25 on the plane where the air outlet 12 is located are the spacing between the two line segments. Since the spacing between the guide grooves 21 is equal, the two projection lengths are also equal, so that the uniform distribution of the guide grooves 21 can be ensured, and the guiding and air passing effects of the anti-condensation structure 2 can be ensured.

[0054] The relationship between the projection length L of the second air outlet 25 on the plane where the air outlet 12 is located and the projection width W2 of the second air outlet 25 on the plane where the air outlet 12 is located is 0.6≤L / W2≤1.6. When L is too small, the number of guide grooves 21 is too large, which affects the air outlet effect of the air outlet component. When L is too large, the number of guide grooves 21 is too small, the guide effect on the fluid is weakened, and the structural strength of the anti-condensation structure 2 is deteriorated. Only when 0.6≤L / W2≤1.6 can the guide effect and structural strength of the anti-condensation structure 2 be guaranteed.

[0055] Preferably, the projections of the first air outlet 24 and the second air outlet 25 on the plane where the air outlet 12 is located are rectangular, elliptical rectangular, elliptical or polygonal.

[0056] The relationship between the depth R3 of the guide groove 21 and the thickness t of the anti-condensation structure 2 is 0.3≤R3 / t≤0.7. When R3 is too large, the structural strength of the part of the anti-condensation structure 2 where the guide groove 21 is located is weakened, affecting the structural strength of the anti-condensation structure 2. When R3 is too small, the guide groove 21 has an insignificant guiding effect on the fluid. Only when 0.3≤R3 / t≤0.7 can the guiding effect of the guide groove 21 and the structural strength of the anti-condensation structure 2 be guaranteed.

[0057] The cross section of the guide groove 21 is semicircular, semi-elliptical, rectangular or triangular.

[0058] The relationship between the minimum distance k1 between the edge of the anti-condensation structure 2 away from the air outlet 12 and the inner wall of the air outlet duct 11 and the width k of the air outlet duct 11 is 0.15≤k1 / k≤0.35, wherein the edge of the anti-condensation structure 2 away from the air outlet 12 can be defined as the starting end of the anti-condensation structure 2, and the fluid will first contact the starting end when contacting the anti-condensation structure 2. When k1 is too small, since the mainstream of the fluid still adheres to the side wall of the air outlet duct 11 and flows, it will cause the fluid to impact the starting end and generate turbulence, and the vortex area near the starting end will increase, affecting the air volume and noise of the air outlet component; when k1 is too large, the anti-condensation structure 2 cannot timely and effectively guide the mainstream of the fluid, and cannot enhance the fluid flow on the leeward side of the air guide plate 3, and the anti-condensation effect becomes weak; only when 0.15≤k1 / k≤0.35, can the guiding effect of the anti-condensation structure 2 and the air volume and noise of the air outlet component be guaranteed.

[0059] The relationship between the minimum distance k2 between the edge of the anti-condensation structure 2 close to the air outlet 12 and the inner wall of the air outlet duct 11 and the width k of the air outlet duct 11 is 0.2≤k2 / k≤0.4. Among them, the edge of the anti-condensation structure 2 close to the air outlet 12 can be defined as the end of the anti-condensation structure 2, and the fluid will flow out from the end when it is about to flow out of the anti-condensation structure 2, that is, the fluid will pass through the starting end and the end in sequence when flowing through the anti-condensation structure 2; when k2 is too small, there is not enough airflow to be diverted to the leeward side of the air guide plate 3, and the anti-condensation structure 2 fails; when k2 is too large, the distance from the end to the air outlet duct 11 is too small and a vortex area will be formed. At this time, the vortex will instead cause the fluid to flow to the windward side of the air guide plate 3, resulting in more fluid on the windward side of the air guide plate 3, and at the same time further compressing the space of the mainstream airflow, affecting the air volume of the air outlet component; only when 0.2≤k2 / k≤0.4 can the guide effect of the anti-condensation structure 2 and the air volume and noise of the air outlet component be guaranteed.

[0060] The air outlet guide member 1 has a first side and a second side adjacent to each other, the air outlet 12 is arranged on the first side, and the air inlet is arranged on the second side, the leeward side of the air guide plate 3 faces the second side, that is, the air inlet direction of the air outlet guide member 1 and the air outlet direction of the air outlet 12 have an angle, so that the air entering the air inlet will gather at the side wall of the air outlet duct 11 to form the mainstream of the fluid, and the distance from the starting end of the anti-condensation structure 2 to the second side is greater than the distance from the end of the anti-condensation structure 2 to the second side, so that the starting end can target the mainstream of the fluid and can guide the fluid to the leeward side of the air guide plate 3, thereby increasing the ability to adjust the air volume on the windward side and the leeward side of the air guide plate 3, avoiding the occurrence of condensation problems, and making the airflow distribution of the air outlet 12 more uniform, avoiding the generation of eddy noise at the air outlet 12, thereby improving the user experience.

[0061] Since the fluid will flow to the air outlet assembly after passing through the heat exchanger, and the size of the heat exchanger is large, the fluid will be dispersed into a larger space first, so the air outlet assembly further includes a guide plate 4, the guide plate 4 is coplanar with the second side surface, and the guide plate 4 is arranged at the air inlet, and the lower edge of the guide plate 4 is sealed with the edge of the air inlet close to the air outlet 12. The guide plate 4 is used to reduce the size of the air inlet, so that the fluid dispersed by the heat exchange of the heat exchanger is gathered to a certain extent, thereby increasing the flow rate of the fluid entering the air outlet duct 11 and ensuring the air supply effect of the air outlet assembly.

[0062] The relationship between the height difference s1 between the edge of the anti-condensation structure 2 away from the air outlet 12 and the upper edge of the guide plate 4 and the height s of the guide plate 4 is 0.08≤s1 / s≤0.28. When s1 is too small or lower than the upper edge of the guide plate 4, the airflow guided by the guide plate 4 cannot be effectively guided by the anti-condensation structure 2; when s1 is too large, the fluid sent into the air inlet will be directly diverted by the anti-condensation structure 2, and the mainstream area of ​​the outlet guide will be more disturbed, which is not conducive to the uniform distribution of air volume. Only when 0.08≤s1 / s≤0.28 can the guiding effect of the anti-condensation structure 2 and the air volume of the air outlet component be guaranteed.

[0063] The height difference s2 between the edge of the anti-condensation structure 2 close to the air outlet 12 and the lower edge of the guide plate 4 and the height s of the guide plate 4 are in the relationship of 0.1≤s2 / s≤0.3. When s2 is too small or lower than the lower edge of the guide plate 4, the diversion of the anti-condensation structure 2 is biased towards the windward side of the guide plate 3, which is not conducive to the distribution of wind volume on the windward side and leeward side of the guide plate 3; when s2 is too large, the fluid diverted from the end will impact the outer wall of the guide plate 3, causing local loss of wind volume and affecting the air volume of the air outlet component. Only when 0.1≤s2 / s≤0.3 can the diversion effect of the anti-condensation structure 2 and the air volume of the air outlet component be guaranteed.

[0064] Specifically, the air outlet assembly further includes a water receiving pan, which is located on one side of the air outlet guide member 1, and the side wall of the water receiving pan constitutes the guide plate 4. The water receiving pan is arranged below the heat exchanger, and it can not only receive the condensed water generated by the heat exchanger, but also guide the fluid flowing through its surface, thereby achieving the guide effect of the guide plate 4.

[0065] The air outlet assembly also includes a shell 5, the air outlet guide member 1 is arranged on the outer wall of the shell 5, and the air outlet guide member 1 and the shell 5 together form the air outlet duct 11, the air outlet duct 11 is connected to the interior of the shell 5, the water receiving tray is arranged in the shell 5, the indoor gas first enters the shell 5, then flows through the heat exchanger above the water receiving tray and enters the air outlet duct 11, and is finally discharged through the air outlet 12, completing the heat exchange process of the gas.

[0066] An indoor unit includes the above-mentioned air outlet assembly. The indoor unit also includes a fan, which is arranged in a housing 5, and the air outlet direction of the fan points to the air inlet of the air outlet guide member 1. At this time, the air inlet takes in horizontal air, and then passes through the deflection effect of the air outlet duct 11 and is discharged vertically through the air outlet 12.

[0067] Preferably, Figure 2 As shown, under the action of the centrifugal fan, the air flow enters from the return air grille on the rear side of the lower surface of the shell 5, is filtered through the filter to form clean air, and then the centrifugal fan drives the air flow to be sucked in axially and discharged horizontally from the volute outlet, blowing to the heat exchanger, and enters the air outlet duct 11 through the air inlet under the guidance of the water receiving tray. At this time, the mainstream of the gas flows on the side away from the heat exchanger, and forms a vortex area near the water receiving tray. Due to the existence of the anti-condensation structure 2, the mainstream of the gas is guided, which not only improves the distribution of the vortex area, but also enables the gas to flow along the windward surface and the guide groove 21, increasing the air flow rate at the first air outlet 24 and the second air outlet 25. The air volume distribution of the entire air outlet component is more uniform, and part of the gas will be guided to the leeward side of the air guide plate 3, thereby reducing the uneven air volume distribution on the windward and leeward sides of the air guide plate 3, and avoiding the occurrence of condensation on the air guide plate 3.

[0068] like Figure 7 and Figure 8 As shown, Figure 7 This is a simulation diagram of the air flow field of the indoor unit when the anti-condensation structure 2 is not provided; Figure 8 This is a simulation diagram of the indoor unit air flow field when the anti-condensation structure 2 is set; when the fan is at the same speed, Figure 7 The wind volume obtained is 479m 3 / h, and Figure 8 The air volume obtained is 471m 3 / h, that is, the air volume of the air outlet 12 of the indoor unit is not much different after the anti-condensation structure 2 is provided, but it can be clearly seen that the anti-condensation structure 2 can improve the air volume distribution of the air outlet 12, reduce the air volume difference on both sides of the air guide plate 3, and achieve the purpose of improving the condensation phenomenon.

[0069] An air conditioning system comprises the above-mentioned air outlet assembly or the above-mentioned indoor unit.
