Description

Technical Field

[0001] The present invention relates to the field of air conditioning equipment, and in particular to a fresh air mechanism and a fresh air air conditioner. Background Art

[0002] Indoor air is polluted by various decorative materials and furniture, including paint, plywood, particleboard, foam filler, interior wall coating, plastic veneer and other materials, which contain formaldehyde, benzene, toluene, ethanol, chloroform and other organic vapors. The above pollutants will slowly release and pollute the indoor air. For this reason, many families install fresh air systems to overcome this problem. However, the fresh air introduced generally does not pass through the heat exchanger, so there will be a temperature difference with the indoor air, which will reduce the comfort experience. Summary of the invention

[0003] Compared with the prior art, the present application has the following characteristics: compared with the prior art, a regulating device for introducing air into the fresh air system is added, so that the introduced air has the same temperature as the indoor air, thereby improving indoor comfort.

[0004] To solve at least one of the above problems, the present invention provides a fresh air mechanism, which is arranged in a fresh air air conditioner with a heat exchange air duct, in which a heat exchanger is provided.

[0005] In the above embodiment, by setting a fresh air intake device outside the fresh air air conditioner, outdoor fresh air is introduced to the air intake side of the heat exchanger, and the temperature of the fresh air introduced by the fresh air intake device is adjusted by the heat exchanger to match the indoor temperature. Compared with the prior art, fresh air with a temperature difference from the indoor temperature will not be directly blown in, avoiding discomfort to indoor users and reducing condensation. At the same time, the temperature of the fresh air introduced by the fresh air intake device can be synchronously adjusted according to the temperature set by the air conditioner.

[0006] Preferably, the fresh air intake device includes an air intake pipe and an air intake box connected to the air intake pipe, an axial flow fan is arranged in the air intake box, and the air intake pipe is connected to the air inlet of the axial flow fan.

[0007] An air inlet pipe is set to lead to the outside to introduce outdoor fresh air, and the outdoor fresh air can be guided to the air outlet of the air inlet box through the axial flow fan. The axial flow fan is set in the air inlet box to improve the safety of the device. At the same time, since the axial flow fan has a large noise, the air inlet box can also isolate the noise to a certain extent.

[0008] Preferably, the opening direction of the air inlet box outlet is upward, and the air inlet box includes a cover plate, which is hinged to one side of the air inlet box outlet and can be driven to rotate above the air inlet box outlet to face the air inlet side of the heat exchanger.

[0009] When the axial flow fan starts working, the fresh air flows along the air inlet pipe to the air inlet box, and at the same time rotates to the top of the air outlet of the air inlet box and toward the air inlet side of the heat exchanger, playing the role of guiding the fresh air to the air inlet side of the heat exchanger. When the axial flow fan is not working, the cover is closed to prevent dust and foreign matter from falling into the air inlet box and affecting the operation of the axial flow fan.

[0010] Preferably, a humidifying device is provided in the air inlet box, a first opening is provided on one side of the air inlet box, and the humidifying device can be drawn out and disposed in the first opening.

[0011] By installing a humidifier, the humidity of outdoor fresh air can be increased, thereby improving the user's comfort; the pull-out setting of the humidifier is convenient for water addition and maintenance.

[0012] Preferably, a purification device is provided in the air inlet box, a second opening is provided on one side of the air inlet box, and the purification device can be drawn out and disposed in the second opening.

[0013] By installing a purification device, the quality of outdoor fresh air can be improved to ensure human health; the pull-out setting of the purification device is convenient for cleaning and replacement.

[0014] Preferably, the fresh air mechanism further includes a fresh air fan assembly, and the outdoor fresh air introduced by the fresh air inlet device passes through the heat exchanger and then enters the air inlet of the fresh air fan assembly.

[0015] By setting up a fresh air fan assembly, the outdoor fresh air that has undergone heat exchange is guided to the outdoors through the fresh air outlet.

[0017] Preferably, the fresh air air conditioner comprises a shell, the shell is provided with an air inlet shared by the heat exchange air duct and the fresh air duct, and the shell is provided with a fresh air outlet connected to the fresh air duct.

[0018] The above arrangement enables indoor air circulation and fresh air duct to share one heat exchanger, thus saving costs and providing high versatility for the fresh air mechanism.

[0019] Preferably, the fresh air intake device is arranged at the rear of the heat exchanger, and the fresh air intake device is arranged at the bottom of the heat exchanger.

[0020] The above arrangement makes the air inlet direction of the fresh air entering the fresh air air conditioner the same as the air inlet direction of the indoor air circulation, thereby directing the fresh air to the air inlet side of the heat exchanger.

[0021] Preferably, the fresh air fan assembly includes a fresh air blade, and the axis of the fresh air blade is in a vertical state.

[0022] By placing the fresh air fan horizontally, its air inlet is closer to the fresh air outlet of the heat exchanger, thereby improving the efficiency of the fresh air flow and ensuring that it is delivered to the room faster; and saving shell space.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 , Figure 4 As shown, a fresh air mechanism provided by the present invention includes a fresh air intake device 1, which is arranged in a fresh air air conditioner having a heat exchange air duct, wherein the heat exchange air duct is used for circulating heat exchange of indoor air, and a heat exchanger 2 is arranged in the heat exchange air duct. The fresh air intake device 1 is arranged outside the housing of the fresh air air conditioner, and the fresh air intake device 1 can lead outdoor fresh air to the air intake side of the heat exchanger 2.

[0037] In the above embodiment, by setting a fresh air intake device 1 outside the fresh air air conditioner housing, outdoor fresh air is introduced to the air intake side of the heat exchanger 2, and the temperature of the outdoor fresh air introduced by the fresh air intake device 1 is adjusted by the heat exchanger 2 to match the indoor temperature. Compared with the prior art, the wind with a temperature difference with the indoor temperature will not be directly blown in, thus avoiding discomfort to indoor users and reducing the generation of condensation. At the same time, the temperature of the wind introduced by the fresh air intake device 1 can be synchronously adjusted according to the temperature set by the fresh air air conditioner.

[0038] In one embodiment, the fresh air intake device 1 is configured to include an air intake pipe 11, an axial flow fan 12 and an air intake box 13, wherein the air intake pipe 11 is connected to the air intake box 13, the axial flow fan 12 is arranged in the air intake box 13, and the air intake pipe 11 is connected to the air inlet of the axial flow fan 12. The air intake pipe 11 of the fresh air intake device 1 can lead to the outside to introduce outdoor fresh air, and the axial flow fan 12 can further guide the outdoor fresh air introduced by the air intake pipe 11 to the air outlet of the air intake box 13; in addition, as the length of the air intake pipe 11 increases, the flow resistance will increase, and the problem of reduced ventilation efficiency can be overcome by adding the axial flow fan 12; the axial flow fan 12 is arranged in the air intake box 13, which also improves the safety of the device. At the same time, since the noise of the axial flow fan 12 is relatively large, the air intake box 13 can also isolate the noise to a certain extent.

[0039] Since the fresh air inlet device 1 of the device and the air inlet 6 of the heat exchanger 2 adopt an open connection form, when the fresh air is introduced, in order to ensure that the fresh air completely enters the air inlet of the heat exchanger 2, the above embodiment is optimized. The fresh air inlet device 1 also includes a cover plate 14, which is hinged to one side of the air outlet of the air inlet box 13, and can be driven to rotate above the air outlet of the air inlet box 13 to face the air inlet side of the heat exchanger 2. When the axial flow fan 12 starts to work, the outdoor fresh air flows into the air inlet box 13 along the air inlet pipe 11. At this time, the opening and closing direction of the cover plate 14 is toward the air inlet side of the heat exchanger 2, which can guide the fresh air to blow to the air inlet side of the heat exchanger 2. When the fresh air starts to be introduced, under the wind guiding effect of the cover plate 14, the fresh air completely flows to the air inlet of the heat exchanger 2, avoiding the fresh air flowing to other places, causing gases with different temperature differences to be blown into the room, reducing the comfort.

[0040] In addition, the cover plate 14 can be set to be one-way open. Here, the cover plate is equivalent to a one-way valve. When the axial flow fan and the fresh air system are not working, the cover plate is automatically closed by gravity to prevent dust and foreign matter from falling into the air inlet box and affecting the operation of the axial flow fan.

[0041] like Figure 2 , Figure 5 As shown, a humidifying device 15 is provided in the air inlet box 13. Preferably, the humidifying device 15 is composed of structures such as a water film and a water tank. By providing the humidifying device 15, the humidity of the outdoor fresh air can be increased, thereby improving the comfort of the user. A first opening 131 is provided on one side of the air inlet box 13, and the humidifying device 15 can be pulled out and arranged in the first opening 131, so as to facilitate the watering and maintenance of the humidifying device 15.

[0042] Preferably, a purification device 16 is also provided in the air inlet box 13. Preferably, the purification device 16 is composed of a filter box and a filter in the filter box and other structures. By providing the purification device 16, the air quality of outdoor fresh air can be improved to ensure human health; a second opening 132 is provided on one side of the air inlet box 13, and the purification device 16 can be pulled out and set in the second opening 132, which is convenient for cleaning and replacement of the filter in the purification device 16.

[0043] In another embodiment, the fresh air mechanism further includes a fresh air fan assembly 3, and the outdoor fresh air introduced by the fresh air intake device 1 passes through the heat exchanger 2 and then enters the air inlet of the fresh air fan assembly 3. Figure 3 As shown, the fresh air fan assembly 3 can blow the fresh air processed by the heat exchanger 2 to a farther distance, and lead it into the room through the fresh air outlet 4, so as to ensure more sufficient indoor air circulation and avoid uneven distribution of fresh air causing reduced indoor comfort.

[0044] The present application also provides a fresh air air conditioner, comprising the fresh air mechanism described in the above technical solution, and thus has the beneficial effects of the above solution.

[0045] Specifically, the fresh air air conditioner includes a heat exchange duct and a fresh air duct. The indoor unit of the fresh air air conditioner includes a shell, the shell is provided with an air inlet 6 shared by the heat exchange duct and the fresh air duct, and the shell is provided with a fresh air outlet 4 connected to the fresh air duct, and the outdoor fresh air after heat exchange flows into the room through the fresh air outlet 4.

[0046] The technical solution adopted in the present application is that the indoor air circulation heat exchange duct and the fresh air duct share a heat exchanger, which simplifies the internal structure and reduces costs. At the same time, it improves the consistency of the fresh air temperature and the circulating air temperature regulated by the fresh air air conditioner, thereby improving the indoor comfort level; and the fresh air mechanism of the present application has higher versatility.

[0047] In summer, the heat exchanger cools, and the fresh air passes through the heat exchanger to lower the temperature before entering the room; in winter, the heat exchanger heats, and the fresh air passes through the heat exchanger to increase the temperature before entering the room. Ensure that the temperature provided by the indoor fresh air air conditioner is the same as the outlet temperature of the fresh air to improve the comfort experience.

[0048] In some embodiments, the fresh air intake device 1 is arranged at the rear of the fresh air air conditioner heat exchanger 2, and the fresh air intake device 1 is arranged at the lower part of the heat exchanger 2. Only by the above arrangement can the air intake direction of the outdoor fresh air entering the housing be the same as the air intake direction of the indoor air circulation, and the fresh air duct and the heat exchange duct share a heat exchanger. In addition, the fresh air intake device 1 is arranged at the rear of the heat exchanger 2 to facilitate installation and wiring. When the fresh air air conditioner device is placed against a wall, the pipeline can be directly led out from the rear.

[0049] An optimization is made on the basis of the above embodiment, in which the fresh air fan assembly 3 includes fresh air blades, and the fresh air blades are preferably centrifugal blades. The axes of the fresh air blades are in a vertical state, that is, the fresh air fan assembly 3 is horizontally placed. Since the fresh air fan assembly 3 needs to be arranged at the lower part of the heat exchanger 2, the air inlet of the fresh air fan assembly 3 is closer to the fresh air outlet of the heat exchanger 2 by horizontally placing the fresh air fan assembly 3, thereby improving the efficiency of the fresh air flow and ensuring that it is delivered to the room faster; and the horizontal placement of the fresh air fan assembly 3 saves the internal space of the shell.

[0050] In addition, since the fresh air fan assembly 3 is a rotating device, it will vibrate during operation. Therefore, the fresh air fan assembly 3 also needs to be placed at the bottom of the fresh air air conditioner device to ensure safety and prevent the center of gravity from being too high, causing mechanical vibration and leading to instability of the fresh air air conditioner device. Therefore, in order to match the fresh air fan assembly 3, the fresh air outlet 4 is set at the front bottom of the fresh air air conditioner device.

[0051] The fresh air outlet 4 is arranged at the front bottom so as to be close to the fresh air fan assembly 3, thereby avoiding the increase of flow resistance due to the long distance, which causes the fresh air to be unable to be transmitted to the corners of the room.

[0052] As an improvement to the above solution, a guide plate 5 is provided at the fresh air outlet 4. The fresh air delivery direction can be changed by adjusting the guide plate 5, so that the direction is controllable and the user experience is improved; in addition, the guide plate 5 can also control the switch state of the fresh air outlet 4.

[0053] As an improvement to the above technical solution, the fresh air intake device 1 is detachably connected to the fresh air air conditioner device. Since the fresh air air conditioner needs to be assembled on site, in order to facilitate transportation and packaging, the fresh air intake device and the fresh air air conditioner device are set to be detachably connected, and the specific connection structure can be a connection form such as a buckle, a bolt, etc.

[0054] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
