As shown in fig. 1 to 4, according to a first aspect of an embodiment of the present utility model, a fresh air structure is provided, including: a fan assembly 110, wherein the fan assembly 110 is provided with an air inlet 111; the joint 120, connect to the above-mentioned air intake 111, the above-mentioned joint 120 opens the first import 121 and second import 122; a first pipe body 130, one end of the first pipe body 130 is connected to the first inlet 121, and the other end is connected to the outdoor space; and a second pipe body 140, wherein the second pipe body 140 is provided with a first end 141, a second end 142 and a third end 143, the first end 141 is used for communicating with the outdoor space, the second end 142 is used for communicating with a water outlet of the air conditioner, and the third end 143 is connected to the second inlet 122.

The fresh air structure provided by the embodiment of the utility model is provided with a fan assembly 110, a connector 120, a first pipe 130 and a second pipe 140. Wherein, fan assembly 110 is used for carrying the new trend, and fan assembly 110 is provided with air intake 111, and air intake 111 communicates in outdoor environment, connects 120 and connects 111 in the air intake, connects 120 and has seted up first import 121 and second import 122, and wherein, first body 130 is connected in first import 121, and first body 130 and outdoor space are linked together. The second pipe body 140 is connected to the second inlet 122, and the second pipe body 140 is formed with a first end 141, a second end 142 and a third end 143, is communicated with the outdoor space through the first end 141, is communicated with the drain hole of the air conditioner through the second end 142, and is connected to the second inlet 122 through the third end 143. So set up, under the condition that new trend structure carried the new trend to indoor, through the power that fan subassembly 110 provided, the new trend in outdoor space carries simultaneously to indoor space from first body 130 and second body 140 through joint 120 and fan subassembly 110, has improved new trend air inlet equivalent diameter, reduces the pipe resistance, and then improves air supply efficiency, improves user experience.

It is understood that the first pipe 130 may be an installed fresh air pipe, and the second pipe 140 may be an existing drain pipe of the air conditioner. The fresh air pipe and the water drain pipe are integrally connected to the fan assembly 110 through the joint 120, so that fresh air can be simultaneously conveyed from the water drain pipe and the fresh air pipe, and fresh air supply quantity is improved. And a new air hole is not required to be additionally drilled on the wall body, so that the installation engineering quantity is reduced, and the degree of damage to the appearance of the wall body is reduced. And so set up, under the prerequisite of guaranteeing equal new trend air supply volume, can reduce the fan rotational speed of fan subassembly 110, reduce the energy consumption, and noise reduction improves user experience.

It will be appreciated that in the case of the air conditioner performing a cooling operation, condensed water generated from the heat exchanger is transferred from the second end 142 of the second pipe body 140 to the first end 141, and discharged from the first end 141 to the outdoor space. In the case of the fresh air structure operation, fresh air of the outdoor space is transferred from the first end 141 to the third end 143, and transferred from the third end 143 to the joint 120 and the fan assembly 110, thereby being transferred to the indoor space.

It is understood that the shapes of the first pipe 130 and the second pipe 140 may be set according to the actual installation state of the fresh air structure, so as to avoid interference. For example, a bend section may be provided to avoid an existing structure.

In some examples, as shown in fig. 1 to 4, the second pipe body 140 includes: and a liquid sealing structure provided between the second end 142 and the third end 143, wherein when the liquid sealing structure is in a liquid sealing state, the liquid in the liquid sealing structure prevents the gas in the passage between the second end 142 and the third end 143 from flowing.

It is understood that the second tube 140 is provided with a liquid seal structure. Specifically, the liquid seal structure is disposed between the second end 142 and the third end 143, the liquid seal structure has a liquid seal state, when the liquid seal structure is in the liquid seal state, the liquid stored in the liquid seal structure can separate the gas passage between the second end 142 and the third end 143 of the second pipe body 140 and the gas passage between the first end 141 and the second end 142, so that the gas is prevented from flowing between the second end 142 and the third end 143 and between the first end 141 and the second end 142, and meanwhile, the gas passage between the first end 141 and the third end 143 of the second pipe body 140 is kept in communication. So set up, under the condition that the air conditioner carries out refrigeration operation, the comdenstion water that the heat exchanger produced gets into in the liquid seal structure through the third end 143 of second body 140 for the gas passageway between second end 142 and the third end 143 of second body 140 cuts off, when making fresh air structure extraction outdoor space's new trend, can not extract the air of heat exchanger department, and the air that outdoor space got into from second end 142 of second body 140 can not carry heat exchanger department, guarantee that new trend carries to third end 143, joint 120 and fan subassembly 110 from first end 141, carry to indoor space through fan subassembly 110, in order normally to indoor space carries new trend. And the liquid sealing action of the liquid sealing structure does not cut off the flow of the liquid in the second pipe body 140, so that the condensed water generated from the air conditioner can be transferred from the second end 142 to the first end 141 to be discharged to the outdoor space. Therefore, the fresh air conveying and the condensed water discharging can be ensured to be carried out smoothly.

It can be appreciated that the temperature of the condensed water is lower, the condensed water in the liquid sealing structure can reduce the temperature in the second pipe body 140, and heat exchange can be performed with the low-temperature condensed water in the process that the fresh air is conveyed from the first end 141 to the third end 143 of the second pipe body 140, so that part of cold energy of the condensed water is recovered, the temperature of the fresh air conveyed to the indoor space is lower, the cooling efficiency of the indoor space can be improved, and the energy utilization rate is improved. And the comdenstion water in the liquid seal structure can effectually block the mosquito and get into in the indoor space from the second end 142 of second body 140, improves user experience.

In some examples, as shown in fig. 1-4, the liquid seal structure described above is a trap 144.

It can be understood that the water trap 144 may be a U-shaped tube structure, and in the case of performing refrigeration operation on the air conditioner, the condensed water generated by the heat exchanger enters the U-shaped tube through the third end 143 of the second tube body 140, and when the liquid level of the condensed water is higher than the height of the communicating area at the bottom of the U-shaped tube, the U-shaped tube has a liquid sealing function. When the liquid level of the condensed water in the U-shaped pipe exceeds the upper limit of the liquid storage of the U-shaped pipe, the condensed water overflows from the U-shaped pipe and flows to the first end 141, so that the second pipe body 140 can normally discharge the condensed water.

In some examples, as shown in fig. 1-4, the third end 143 is higher than the highest point of the trapway 144.

It can be appreciated that the height of the lowest point of the third end 143 is higher than the height of the highest point of the trap 144, so that the condensate water in the trap 144 is prevented from overflowing beyond the upper limit of the trap 144 and flowing into the third end 143, and the condensate water is conveyed from the third end 143 to the fan assembly 110 under the pumping force provided by the fan assembly 110, which easily causes short circuit of the parts in the fan assembly 110, and cannot work normally, thereby bringing about potential safety hazard. The reliability is improved. And so set up, can guarantee that the new trend in outdoor space can carry to third end 143 smoothly from the first end 141 of second body 140, can not receive the influence of the comdenstion water in the trap 144.

In some examples, the above fresh air structure further comprises: the liquid level detecting member is disposed in the trap 144 and is used for detecting the liquid level in the trap 144.

It can be appreciated that the fresh air structure is also provided with a liquid level detection member. Specifically, the liquid level detecting member may be disposed in the trap 144, and is configured to detect whether the liquid level of the condensed water in the trap 144 reaches a preset level. Under the condition that the liquid level of the condensed water in the trap 144 reaches the preset height, the trap 144 can be determined to be in a liquid sealing state, and the second pipe body 140 can be ensured to normally drain and convey fresh air. In the event that the level of condensate within the trap 144 is detected to be below a preset level, it may be determined that the trap 144 is not in a liquid-tight condition. At this time, the second pipe 140 is not suitable for delivering fresh air, and the level of condensed water in the trap 144 should be waited for reaching a preset level. So that the second pipe 140 can be accurately held during use, and the reliability is improved.

In some examples, the equivalent diameter dimension of the first tube 130 and the second tube 140 is 33mm to 35mm.

It is understood that the sum of the effective air supply diameters of the first and second duct bodies 130 and 140 is an equivalent diameter, and the equivalent diameter affects the air supply amount. If the equivalent diameter is too small, the air supply efficiency is low, and the requirement of rapid ventilation of a user cannot be met. If the equivalent diameter is too large, the pipe diameter of the existing first pipe body 130 cannot meet the requirement, and a larger fresh air hole is needed on the wall body, so that the installation engineering amount is increased, and the appearance damage degree to the wall body is increased. Therefore, the equivalent diameter sizes of the first and second duct bodies 130 and 140 are set to 33 to 35mm, so that fresh air holes do not need to be additionally drilled in the wall body while the air supply quantity is ensured, the installation engineering quantity is reduced, and the degree of damage to the appearance of the wall body is reduced. So set up, compare in the correlation technique, at fan assembly 110 equi-rotational speed, fresh air amount of wind promotes the volume more than or equal to 10%.

In some examples, as shown in fig. 1-3, the fan assembly 110 described above includes: the volute 112 is provided with the air inlet 111 and the air outlet 113, wherein the air outlet 113 is used for conveying fresh air to the indoor space; the fresh air wind wheel is arranged in the shell.

It will be appreciated that the fan assembly 110 is provided with a volute 112 and fresh air wind wheel. Wherein, the air intake 111 and the air outlet 113 have been seted up to the spiral case 112, the air intake 111 is connected in the joint 120, the air outlet 113 is connected in the air conditioner, and new trend wind wheel sets up in spiral case 112, new trend wind wheel optional centrifugal wind wheel, centrifugal wind wheel starts the back, the negative pressure that produces makes the new trend in outdoor space carry in air intake 111 through first body 130 and second body 140, the centrifugal force that produces through centrifugal wind wheel again does work, improve new trend pressure and wind speed, blow to indoor space from air outlet 113 in, improve air supply distance and air supply efficiency, in order to realize the high-efficient ventilation to indoor space.

If the fresh air is directly conveyed into the environment after the effect of the centrifugal wind wheel, the wind speed felt by a user is too high, the body feeling is hard, and the discomfort is easily caused. By arranging the volute 112, the speed of the air flow is gradually reduced, so that the kinetic energy of a part of air is changed into static pressure, the air speed in the environment is ensured to be proper, and the comfort level of a user is improved. And after the wind speed is reduced, the friction between the air and the air conditioner component is reduced, the noise is effectively reduced, and the user experience is improved. And a volute tongue is formed at the extension part from the spiral line of the volute 112 to the section of the air outlet 113, and part of air flow is prevented from circulating in the volute 112 by the volute tongue. The air supply loss is reduced, and the air supply quantity is further improved.

In addition, according to the environmental noise requirement and the specific condition of the installation position, the arc radius of the arc surface of the volute tongue can be set, and the arc radius and the noise value are in inverse proportion. Meanwhile, the gap between the volute tongue and the outer diameter of the impeller of the centrifugal wind wheel can be reduced, the generated noise is reduced, the noise pollution is reduced, and the user experience is improved.

In some examples, the above fresh air structure further comprises: and a sealing member provided at a junction between the joint 120 and the air inlet 111.

It is understood that the fresh air structure is also provided with a sealing member. Specifically, the sealing member is disposed at the connection between the connector 120 and the air inlet 111, so as to avoid leakage of fresh air from the connection between the connector 120 and the air inlet 111, resulting in air supply loss and further improving air supply.

Illustratively, the sealing member may be a rubber sealing ring, which is sleeved at the joint of the joint 120 and the air inlet 111, and the periphery of the rubber sealing ring may be coated with a sealant, so as to further ensure the sealing effect.
