Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0047] The jet air conditioning unit 10 is a new type of air conditioning system that uses jet technology to circulate and regulate air. The working principle of the jet air conditioning unit 10 is to accelerate and discharge air through jet technology, thereby generating negative pressure and attracting surrounding air into the unit. This design can achieve efficient air circulation and effectively regulate indoor temperature and humidity.

[0048] The jet air conditioning unit 10 has the advantages of high efficiency, energy saving, quietness, easy installation and maintenance, etc. It is suitable for a variety of places, such as offices, shopping malls, hotels, hospitals, etc., and can provide a comfortable indoor environment. However, due to the low temperature of the cold air sprayed by the spherical nozzle 31 of the jet air conditioning unit 10 or improper design, the cold air contacts the surrounding environment, and condensation is more likely to occur on the surface of the spherical nozzle 31.

[0049] Condensation on the spherical nozzle 31 affects the user experience and may also cause corrosion on the surface of the spherical nozzle 31 and surrounding equipment, affecting the normal operation and service life of the unit. At the same time, condensation may drip onto electrical equipment or the ground, posing a safety hazard of electrical short circuit and pedestrian slipping.

[0050] In the related art, in order to reduce the problem of condensation generated by the spherical nozzle 31, the condensation can be reduced by adjusting the working parameters of the air conditioning unit, such as temperature and humidity, and by providing insulation materials on the inner and outer surfaces of the spherical nozzle 31. However, the anti-condensation effect achieved by these methods is not ideal.

[0051] Based on this, see Figure 1 as well as Figure 2The embodiment of the present application provides a jet air conditioning unit 10, which can improve the anti-condensation effect of the spherical nozzle 31 and improve the user experience. The jet air conditioning unit 10 includes: a box body 1, a fan 2 and a nozzle 3.

[0052] The box body 1 has an installation cavity 11 . The fan 2 is disposed in the installation cavity 11 and connected to the nozzle 3 to introduce the air after heat exchange into the nozzle 3 .

[0053] It is understandable that the air after heat exchange in the box body 1 enters the fan 2 through the air inlet of the fan 2, then flows through the nozzle 3 connected to the air outlet of the fan 2, and is then ejected out of the box body 1.

[0054] Exemplarily, the fan 2 may be a centrifugal fan or an axial flow fan.

[0055] The jet air conditioning unit 10 further includes a motor 5 , which is disposed in the installation cavity 11 , and a driving shaft of the motor 5 is connected to a rotating shaft of the fan 2 , thereby driving the fan 2 to rotate.

[0056] See also Figure 3 The box body 1 is provided with a first mounting hole 12 , and the first mounting hole 12 is communicated with the mounting cavity 11 . The nozzle 3 is connected to the box body 1 and is arranged at the first mounting hole 12 .

[0057] It can be understood that the first mounting hole 12 is an air outlet of the jet air conditioning unit 10 , and the air in the box body 1 is ejected out of the box body 1 through the first mounting hole 12 .

[0058] Exemplarily, the number of the first mounting holes 12 is one or more, which is not limited in the present application.

[0059] It should be noted that the embodiment of the present application is described by taking the example that the number of the first mounting holes 12 is two.

[0060] For further information, see Figure 4 The box body 1 is also provided with a second mounting hole 13 , which is communicated with the mounting cavity 11 . The second mounting hole 13 is the air inlet of the jet air conditioning unit 10 , and the air outside the box body 1 enters the box body 1 through the second mounting hole 13 .

[0061] Exemplarily, the second mounting hole 13 can be a square hole, a round hole or other shapes. Exemplarily, the shape of the second mounting hole 13 is set to a square hole, and the entire side wall of the box body 1 can be set as the second mounting hole 13, which increases the air intake area of ​​the second mounting hole 13 and improves the air intake efficiency.

[0062] It can be understood that the second mounting hole 13 and the first mounting hole 12 of the jet air-conditioning unit 10 are arranged on opposite sides of the box body 1, which can form a better air flow path and help prevent the indoor air from being directly drawn back into the jet air-conditioning unit 10 to form a backflow.

[0063] See also Figure 3 Combined with Figure 4 The housing 1 of the jet air conditioning unit 10 includes a frame 14 and a wall panel 15. The frame 14 defines a plurality of installation areas, and the wall panel 15 is arranged in the installation area. The frame 14 includes a mounting portion extending toward the center of the installation area, and the mounting portion is located on the side of the wall panel 15 facing the inside of the housing. When the fan 2 is running at a high speed, the housing 1 is in a negative pressure state, and the wall panel 15 is subjected to pressure from the outside to the inside. In this way, the wall panel 15 can better fit the frame 14 under the action of the pressure from the outside to the inside, thereby reducing the air leakage rate of the jet air conditioning unit 10.

[0064] Exemplarily, the frame 14 of the box body 1 may be made of an aluminum alloy frame, which can improve the strength and corrosion resistance of the frame 14 .

[0065] Exemplarily, the wall panel 15 can be made of cyclopentane foam board, or can be made of integral polyurethane foam, or can be made of high-multiple polyethylene board or glass wool wall panel. These materials have good thermal insulation performance and can effectively avoid air heat exchange inside and outside the jet air conditioning unit 10.

[0066] It is understandable that the jet air conditioning unit 10 further includes an electrical box 6, and the electrical equipment is arranged in the electrical box 6. The electrical box 6 is fixedly connected to the side wall of the box body 1 to prevent external objects, water and dust from entering the electrical box 6, thereby protecting the electrical equipment from damage.

[0067] In order to facilitate the maintenance of the jet air conditioning unit 10, the housing 1 is also provided with an inspection door 16, which is arranged on a wall plate 15 parallel to the air flow direction F1. In order to facilitate opening or closing the inspection door 16, a door handle 17 is also arranged on the inspection door 16.

[0068] It is understandable that, in order to facilitate the hanging of the jet air conditioning unit 10, a hanger 4 is further provided at the bottom of the outer side of the box body 1. Both ends of the hanger 4 extend to both sides of the box body 1, and for the convenience of hanging, both ends of the hanger 4 are provided with hanging holes 41.

[0069] Exemplarily, the hanger 4 can be made of hot-dip galvanized steel plate, which can improve the strength and corrosion resistance of the hanger 4.

[0070] See also Figure 5 Combined with Figure 4The jet air conditioning unit 10 further includes: an air inlet filter 7 and a heat exchanger 8. The air inlet filter 7 is used to filter the air entering the jet air conditioning unit 10 to prevent dust, particles, bacteria and other pollutants from entering the system, protect the equipment and ensure indoor air quality. The heat exchanger 8 is used to heat or cool the air entering the jet air conditioning unit 10.

[0071] Exemplarily, the air inlet filter 7 can be a primary air filter, a particulate filter, a high efficiency air filter or a UV-C light oxidation filter, etc. When the jet air conditioning unit 10 is produced and organized, a suitable filter can be selected according to specific process requirements and occasion conditions.

[0072] Exemplarily, the heat exchanger 8 generally adopts a tubular heat exchanger or a plate heat exchanger structure. The tubular heat exchanger is suitable for high temperature and high pressure conditions, is easy to clean and maintain, has strong corrosion resistance, and can be flexibly combined. The plate heat exchanger has the advantages of high efficiency, small footprint, detachable cleaning, and suitable for low temperature heat exchange. When the jet air conditioning unit 10 is produced and organized, the appropriate type of heat exchanger can be selected for application according to specific process requirements and occasion conditions.

[0073] The air inlet filter 7 is arranged at the second mounting hole 13, and can filter the air entering the second mounting hole 13. Exemplarily, the air inlet filter 7 is sealed and connected to the hole wall of the second mounting hole 13, and external air can be prevented from entering the mounting cavity 11 through the gap between the air inlet filter 7 and the hole wall of the second mounting hole 13.

[0074] The heat exchanger 8 is disposed at the second mounting hole 13 and is located on a side of the air inlet filter 7 close to the mounting cavity 11 , and is used for heating or cooling the air entering the mounting cavity 11 through the second mounting hole 13 .

[0075] The working process of the entire jet air conditioning unit 10 is as follows: the motor 5 runs, driving the fan 2 to work, sucking the air outside the box 1 through the second mounting hole 13, entering the fan 2 through the air inlet of the fan 2, and then entering the nozzle 3 through the air outlet of the fan 2 and ejecting out of the box 1 through the first mounting hole 12. It can be understood that when the air enters the second mounting hole 13, the air inlet filter 7 and the heat exchanger 8 filter and heat the air, and the air entering the box 1 has been processed.

[0076] It should be noted that see Figure 5 Combined with Figure 6 The jet air conditioning unit 10 is also provided with a water receiving pan 9, which is arranged at the bottom of the installation cavity 11, and a drainage pipe 91 is also provided on the water receiving pan 9.

[0077] It is understandable that when the water vapor in the air condenses into liquid water on the surface of the heat exchanger 8 , the condensed water will be collected in the water receiving pan 9 and then discharged to the outside through the drain pipe 91 .

[0078] In this way, water droplets can be prevented from dripping into the interior of the unit or the indoor space, causing pollution or damaging the equipment. Meanwhile, the design of the water receiving tray 9 can effectively prevent condensed water from leaking, keeping the air conditioning unit and the indoor space dry and clean.

[0079] It is understandable that, for the convenience of maintenance, the maintenance door 16 and the water inlet and outlet pipes of the heat exchanger 8 and the drain pipe 91 of the water receiving pan 9 are arranged on the same side.

[0080] See also Figure 7 The nozzle 3 of the jet air conditioning unit 10 includes: a spherical nozzle 31, a support member 32 and a first insulation layer 33.

[0081] For details, see Figure 8 The spherical nozzle 31 includes an inner side 311 and an outer side 312, and the spherical nozzle 31 is used to spray the heat-exchanged air to the outside of the box body 1. The inner side 311 of the spherical nozzle 31 forms a columnar air duct 313, and the inner diameter of the air duct 313 gradually decreases along the flow direction of the air, which can increase the flow rate of the air.

[0082] For further information, see Figure 8 Combined with Fig. 9 The nozzle 3 further includes a second thermal insulation layer 34 and a third thermal insulation layer 35. The second thermal insulation layer 34 is disposed on the inner side 311 of the spherical nozzle 31 to prevent the air after heat exchange from contacting the inner side 311 of the spherical nozzle 31. The third thermal insulation layer 35 is disposed on the outer side 312 of the spherical nozzle 31 to prevent the air outside the box 1 from contacting the outer side 312 of the spherical nozzle 31.

[0083] In this way, the contact between the spherical nozzle 31 and the air outside the box 1 can be effectively reduced, the temperature drop of the spherical nozzle can be reduced, and condensation on the spherical nozzle can be avoided, thereby improving the user experience and increasing the service life of the spherical nozzle.

[0084] Exemplarily, the material of the second thermal insulation layer 34 may be thermal insulation cotton or other thermal insulation materials, and the thermal insulation cotton has a good thermal insulation effect.

[0085] Exemplarily, the material of the third insulation layer 35 can be flocking cloth or other insulation materials. The third insulation layer 35 is arranged on the outer side 312 of the spherical nozzle 31. The material properties of the flocking cloth can reduce the distance between the spherical nozzle 31 and the support member 32 to avoid air leakage.

[0086] Continue to see Fig. 9 Combined with Fig.10The support member 32 of the nozzle 3 includes a first connection portion 321 and a support portion 323 connected to each other. The first connection portion 321 is used to connect to the box body 1, and the support portion 323 is arranged in the installation cavity 11, and an active cavity 3231 is formed inside. The spherical nozzle 31 is movably arranged in the active cavity 3231, so that the ejection direction of the air can be adjusted.

[0087] During the cooling process of the jet air conditioning unit 10, the first heat-insulating layer 33 of the nozzle 3 is used to prevent the cold air after heat exchange from contacting the outer peripheral side of the support portion 323. The outer peripheral side of the support portion 323 is in the installation cavity 11, and the air after heat exchange is also in the installation cavity 11. The first heat-insulating layer 33 can isolate the air after heat exchange from contacting the outer peripheral side of the support portion 323, avoiding the air after heat exchange from exchanging heat with the support portion 323, thereby facilitating the temperature reduction of the outer peripheral side of the support portion 323.

[0088] It is understandable that, since the spherical nozzle 31 is movably arranged in the installation cavity 11 of the support portion 323, the cold air after heat exchange enters the installation cavity 11, and the temperature of the outer peripheral side of the support portion 323 decreases, which further affects the temperature of the spherical nozzle 31 and reduces the temperature of the spherical nozzle 31. The part of the spherical nozzle 31 outside the box 1 is in contact with the space outside the box 1. If the temperature of the spherical nozzle 31 is too low and the temperature difference with the air outside the box 1 is too large, water vapor is easy to condense on the surface of the spherical nozzle 31 to produce condensation, affecting the user experience.

[0089] Therefore, during the cooling process, the jet air conditioning unit 10 in the embodiment of the present application introduces the air entering the box 1 into the nozzle 3 through the fan 2, and sprays it into the outside of the box 1 through the nozzle 3, thereby adjusting the air in the space outside the box 1. By setting the first insulation layer 33 outside the support portion 323 of the nozzle 3 support member 32, the contact between the cold air after heat exchange in the box 1 and the support portion 323 is reduced, thereby reducing the heat exchange between the air after heat exchange in the box 1 and the support portion 323, and reducing the temperature drop of the support portion 323. Since the spherical nozzle 31 is set in the active cavity 3231 inside the support portion 323, the temperature drop of the spherical nozzle 31 can be reduced, and condensation on the spherical nozzle 31 can be further avoided, which can improve the user experience and increase the service life of the spherical nozzle 31.

[0090] In some embodiments, the first thermal insulation layer 33 is disposed on the outer peripheral side of the support portion 323 and surrounds the support portion 323 .

[0091] It is understandable that the first heat-insulating layer 33 is arranged around the support portion 323, so that the entire support portion 323 is isolated from the heat-exchanged air in the installation cavity 11, and the support portion 323 is prevented from contacting with the heat-exchanged air to generate heat exchange. In this way, the temperature change of the support portion 323 can be small, thereby reducing the impact on the temperature of the spherical nozzle 31.

[0092] See also Fig.11 A first connection hole 322 is formed on the first connection portion 321 , and the support portion 323 is installed on the box body 1 through the first connection hole 322 of the first connection portion 321 .

[0093] See also Fig.12 The nozzle 3 further includes a decorative ring 36, which is disposed on a side of the first connection portion 321 away from the first insulation layer 33 and can shield the first connection portion 321, thereby making the appearance of the jet air conditioning unit 10 more beautiful.

[0094] Exemplarily, the support portion 323 and the box body 1 are mounted by screws, etc.

[0095] In some embodiments, see Fig.11 The support member 32 further includes a second connection portion 324, which is connected to the support portion 323. The first connection portion 321 and the second connection portion 324 are spaced apart in the axial direction of the support portion 323. A second connection hole 325 is also formed in the second connection portion 324.

[0096] For example, see Fig.13 Combined with Fig. 9 , the distance between the first connection portion 321 and the second connection portion 324 can be adjusted.

[0097] The first insulation layer 33 is connected to the first connection part 321 and the second connection part 324 at two opposite ends in the axial direction of the support part 323, respectively. In this way, the first insulation layer 33 can be fixed more firmly on the outer side 312 of the support part 323, which can play a better insulation role for the support part 323.

[0098] In some embodiments, at least one thermal insulation cavity 327 is formed between the first thermal insulation layer 33 and the support portion 323 .

[0099] Understandably, see Fig.14 , Fig.15 as well as Fig.16 , a plurality of reinforcing plates 326 may be provided on the first thermal insulation layer 33 or the support portion 323, and the plurality of reinforcing plates 326 divide the space between the first thermal insulation layer 33 and the support portion 323 into a plurality of thermal insulation chambers 327. The reinforcing plates 326 may support and reinforce the first thermal insulation layer 33 to prevent the first thermal insulation layer 33 from deforming. If the first thermal insulation layer 33 is deformed, the deformed first thermal insulation layer 33 is prone to air leakage, which will affect the heat exchange effect between the insulating support portion 323 and the air after heat exchange, and thus the effect of preventing condensation will also be weakened.

[0100] In some embodiments, see Fig.17The first thermal insulation layer 33 and the support portion 323 are spaced apart, and a thermal insulation cavity 327 is formed between the first thermal insulation layer 33 and the support portion 323 .

[0101] In this way, a heat-insulating cavity 327 is formed between the first heat-insulating layer 33 and the supporting portion 323 .

[0102] Exemplarily, the heat preservation chamber 327 may be a closed cavity. Exemplarily, the heat preservation chamber 327 may be a vacuum chamber.

[0103] It can be understood that the heat preservation cavity 327 can reduce the air flow between the first heat preservation layer 33 and the support portion 323, and can reduce the heat exchange between the first heat preservation layer 33 and the support portion 323, thereby achieving a heat preservation effect.

[0104] Exemplarily, the heat preservation cavity 327 may also be filled with some heat preservation materials, such as polystyrene (EPS), polyurethane (PU), mineral wool, polyethylene (PE) and silicate heat preservation materials.

[0105] In some embodiments, see Fig.18 The support portion 323 includes a first sub-portion 3232, a second sub-portion 3233 and a third sub-portion 3234 which are sequentially connected along the axial direction of the support portion 323. The first sub-portion 3232 and the third sub-portion 3234 are respectively connected to the first connecting portion 321 and the second sub-portion 3233, the second sub-portion 3233 is connected to the first thermal insulation layer 33, a thermal insulation cavity 327 is formed between the first sub-portion 3232 and the first thermal insulation layer 33, and another thermal insulation cavity 327 is formed between the third sub-portion 3234 and the first thermal insulation layer 33.

[0106] In this way, the second sub-portion 3233 can be connected to the first insulation layer 33, and can support and strengthen the first insulation layer 33. At the same time, since the second sub-portion 3233 is connected to the first insulation layer 33, the size of the first insulation layer 33 in the direction A perpendicular to the axial line of the nozzle 3 can be reduced.

[0107] In some embodiments, see Fig.19 The support portion 323 includes an inner arc surface 3235. The inner arc surface 3235 of the support portion 323 forms an active cavity 3231, and the spherical nozzle 31 is rotatably installed in the active cavity 3231. Since the spherical nozzle 31 is spherical, the inner arc surface 3235 is designed to be a spherical arc surface with a radius slightly larger than the radius of the spherical nozzle 31. The spherical nozzle 31 can move in the active cavity 3231 and adjust the direction, thereby adjusting the direction of the air ejected from the box body 1.

[0108] The support portion 323 further includes an outer arc surface 3236. It is understandable that, in order to facilitate processing, the outer arc surface 3236 is designed as a spherical arc surface. In this way, at least one insulation cavity 327 is formed between the outer arc surface 3236 and the first insulation layer 33, which can enhance the insulation effect and reduce the size of the support portion 323 perpendicular to the axial direction A of the nozzle 3, thereby further reducing the size of the nozzle 3.

[0109] In some embodiments, the first heat-insulating layer 33 is respectively sealed and connected to the first connecting portion 321 and the second connecting portion 324. In this way, the first heat-insulating layer 33 can isolate the supporting portion 323 from the cold air after heat exchange, and the heat-insulating effect is better.

[0110] For example, see Fig.14 The first thermal insulation layer 33 includes a fixing plate 331, which is used to be fixedly connected to the second connection part 324. The fixing plate 331 is provided with a third connection hole 332, and the second connection hole 325 is connected to the third connection hole 332 by screws or bolts, so that the second connection part 324 and the fixing plate 331 can be fixedly connected, thereby realizing the connection between the first thermal insulation layer 33 and the support part 323.

[0111] In some embodiments, at least one heat-insulating cavity 327 is formed between the first heat-insulating layer 33 and the supporting portion 323 , and the heat-insulating cavity 327 is an annular cavity surrounding the supporting portion 323 .

[0112] In this way, at least one annular heat-insulating cavity 327 is formed between the first heat-insulating layer 33 and the supporting portion 323 , which can enhance the heat-insulating effect on the supporting portion 323 .

[0113] In some embodiments, the first insulation layer 33 is sealed and connected to the first connection part 321 and the second connection part 324 respectively, and at least one insulation cavity 327 is formed between the first insulation layer 33 and the support part 323 , and the insulation cavity 327 is an annular cavity surrounding the support part 323 .

[0114] In this way, the first thermal insulation layer 33 can isolate the support portion 323 from the cold air after heat exchange, reduce the temperature drop of the support portion 323, and then reduce the temperature drop of the spherical nozzle 31, thereby reducing the occurrence of condensation on the spherical nozzle 31. At the same time, since the annular thermal insulation cavity 327 is formed between the first thermal insulation layer 33 and the support portion 323, the thermal insulation effect of the support portion 323 can be enhanced.
