A fan is a household appliance that uses an electric motor to drive the blades to rotate to accelerate the circulation of air. With the advancement of technology, air conditioners that can cool the air have also appeared. Air conditioners are a type of refrigeration device. Air conditioners are short for air conditioners. Air conditioners process the temperature, humidity, purity, and air flow speed of the air to meet people's production and life needs. The earliest household air conditioners were wall-mounted air conditioners, but since wall-mounted air conditioners are usually fixed on the wall for use, there are certain restrictions. Therefore, mobile air conditioners have appeared to enhance the convenience of mobile use of air conditioners.

[0003] Chinese Patent Publication No. CN219300894U discloses a mobile air conditioner comprising a cooling assembly and a heating assembly. The cooling assembly comprises a cooling inlet for admitting indoor air to the cooling assembly and a cooling outlet for discharging the cold air produced by the cooling assembly. The heating assembly comprises a heating inlet for admitting indoor air to the heating assembly and a heating outlet for discharging the hot air produced by the heating assembly. The cooling and heating assemblies of the mobile air conditioner are relatively independent, ensuring operational stability and reliability. Furthermore, the outlet direction can be adjusted by rotating the mobile air conditioner, facilitating operation.

[0004] However, in fact, the mobile air conditioner disclosed in the above patent document is essentially a combination of the indoor unit and outdoor unit of a traditional wall-mounted air conditioner.

[0044] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0045] Such as Figure 1As shown in the figure, the present utility model discloses a novel local refrigeration device combining an air conditioner and a fan, which includes a fan body 1 and an air conditioner component 2. The air conditioner component 2 is used to cool the surrounding air into cold air, and the fan body 1 forms a wind flow to blow the cold air out, so as to cool only the area close to the person or object in need, specifically for local area refrigeration, and effectively and economically realize the function of close-range refrigeration and cooling. Specifically, the fan body 1 includes a fan column 101 and a blowing head 102 connected to the fan column 101. The fan body 1 also includes a base 103. The fan column 101 is connected to the base 103, so that the base 103 supports the whole fan body 1. The blowing head 102 includes a fan motor and fan blades. The fan motor drives the fan blades to rotate to form a wind flow. A fan cover is also arranged outside the fan blades, and the fan cover wraps the fan blades inside to achieve a safety effect.

[0046] The fan column 101 is connected to the base 103 and coincides with the central axis of the base 103, that is, the center of gravity of the blowing head 102 and the fan column 101 is located at the center of the base 103, with good stability and not easy to tip over. A first moving wheel 104 is arranged below the base 103, which is beneficial to the flexible movement of this local refrigeration device to different positions for use.

[0047] As Figures 2 to 9 and Figures 11 to 14 shown in the figure, the air conditioner component 2 includes a housing 201. The housing 201 is provided with an assembly groove 2011. One combination method of the fan body 1 and the air conditioner component 2 is to use them in an overlapping manner. As Figure 1 shown in the figure, when the fan body 1 and the air conditioner component 2 are used in an overlapping manner, the fan column 101 is correspondingly embedded in the assembly groove 2011. A refrigeration component is arranged inside the housing 201. An air outlet pipe component is connected to the housing 201. One end of the air outlet pipe component is connected to the refrigeration component, and the other end of the air outlet pipe component extends close to the blowing head 102, that is, the cold air coming out of the refrigeration component is output to the area where the wind flow is formed by the blowing head 102. The cold air after being cooled by the refrigeration component is discharged from the air outlet pipe component and is blown out under the drive of the wind flow formed by the blowing head 102. Therefore, cold air can be felt in the close range area sensed by the wind flow, and the cooling effect in the close range is good.

[0048] In this embodiment, the fan column 101 is in the shape of a straight rod; the assembly groove 2011 runs through the housing 201 in the axial direction and extends into the recess in the radial direction of the housing 201. The width dimension of the assembly groove 2011 is greater than the diameter dimension of the fan column 101. When the air-conditioning component 2 is used in combination with the fan body 1, the housing 201 is placed on the base 103, and the assembly groove 2011 is correspondingly embedded with the fan column 101. When the air-conditioning component 2 is stacked on the base 103 of the fan body 1, the assembly groove 2011 can be aligned with the fan column 101 and embedded for placement; the housing 201 is in the shape of a cylinder, and the ratio between the diameter and the height of the housing 201 is 1:1.2 to 1.8. In this embodiment, the ratio between the diameter and the height of the housing 201 is 1:1.3. Because it is found in multiple tests that the stability of the housing 201 with such a proportional structure when stacked on the base 103 is good, and the overall structure is also more beautiful and compact.

[0049] A handle position 2015 is provided on the side wall of the housing 201, which is beneficial to the handling of the housing 201.

[0050] A first air inlet position 2012 is provided on the housing 201; the refrigeration component includes a compressor 3, a condenser 4, a throttling device, and an evaporator 5; the compressor 3 drives the refrigerant to circulate between the condenser 4, the throttling device, and the evaporator 5; the first air inlet position 2012 corresponds to the evaporator 5, the evaporator 5 is connected to the first fan 6, the first fan 6 is connected to one end of the output pipe 7, and the other end of the output pipe 7 is connected to the air outlet pipe component; after the first fan 6 is started, an air flow is formed to make the surrounding air enter from the first air inlet position 2012, flow through the evaporator 5 to complete refrigeration, and then be transported to the air outlet pipe component through the output pipe 7; the evaporator 5 is made of hydrophilic aluminum foil and high-efficiency internal spiral copper tubes to improve the evaporation effect and reduce energy consumption.

[0051] As Figure 7 shown, the condenser 4 includes an alloy tube 401 for the flow of the refrigeration working medium. A microporous spraying component 402 is provided on the alloy tube 401. The microporous spraying component 402 is connected to a water tank, and the water in the water tank is pumped to the micropores of the microporous spraying component 402 to spray the alloy tube 401, so as to improve the heat exchange efficiency, reduce the exhaust pressure and the condensation power consumption, and thus reduce the energy consumption.

[0052] The air outlet pipe component includes an air outlet hose 8 and an air outlet nozzle 9 connected to the air outlet hose 8. The air outlet hose 8 is made of plastic and has a certain softness, which is beneficial to the matching use with different blowing heads 102 within a certain height range, and is also beneficial to adjusting the air outlet direction of the air outlet nozzle 9. The air outlet hose 8 is connected to the output pipe 7; the air outlet nozzle 9 is rotatably assembled on the air outlet hose 8, so that the air outlet nozzle 9 can be set to be horizontal or vertical, so that the cold air can be blown out horizontally or vertically.

[0053] A hanging member 10 for fixing to the blowing head 102 is provided on the air outlet hose 8. The upper end of the air outlet hose 8 is suspended at the blowing head 102 through the hanging member 10, so that the air outlet nozzle 9 is close to the air flow at the blowing head 102, facilitating the blowing out of the cold air coming out of the air outlet nozzle 9.

[0054] A second air inlet position 2013 is provided on the housing 201. A second fan 11 is connected to the condenser 4. An air outlet position 2014 is provided on the outer wall surface of the housing 201. After the second fan 11 is started, an air flow is formed to allow the surrounding air to enter the housing 201 from the second air inlet position 2013, pass through the condenser 4 and finally blow out from the air outlet position 2014, thereby discharging the internal heat of the housing 201; combined Figures 2 to 5 Look, both the first air inlet position 2012 and the second air inlet position 2013 are set as filter meshes, which helps to filter and isolate large impurities in the air and prevent them from entering the interior of the housing 1; and the first air inlet position 2012 and the second air inlet position 2013 are respectively located on both sides of the inner wall of the assembly groove 2011; that is, as shown in the figure, the housing 201 is formed in a U shape, and the assembly groove 2011 is the opening of the U shape; the second air inlet position 2013 is located on one side within the opening, and the first air inlet position 2012 is located on the other side within the opening; first of all, the first air inlet position 2012 and the second air inlet position 2013 are respectively located on both sides of the inner wall of the assembly groove 2011, achieving a certain hidden and aesthetic effect; secondly, the air outlet position 2014 is located on the side of the outer wall of the housing 201 away from the second air inlet position 2013, that is, the heat dissipation channel formed from the second air inlet position 10 to the air outlet position 2014 is U-shaped. The surrounding air enters the housing 1 from the second air inlet position 10 and finally blows out from the air outlet position 11. At this time, the air flow inside the housing 1 is U-shaped, basically covering the internal space of the housing 1, which helps to completely blow out the heat inside the housing 1.

[0055] The first air inlet position 2012 and the air outlet position 2014 are staggeredly arranged in the height of the housing 201. The second air inlet position 2013 is located above, and the air outlet position 2014 is located below, which can prevent the air flow that enters from the first air inlet position 2012 and is about to flow to the evaporator 5 from discharging from the air outlet position 2014, helping to make the air volume entering from the first air inlet position 2012 be refrigerated as much as possible and reducing air flow loss.

[0056] Moreover, the ratio of the height dimension of the area occupied by the first air inlet position 2012 to the height dimension of the housing 201 is 1 / 2 to 5 / 6, that is, the first air inlet position 2012 occupies a relatively large area on the side wall of the assembly groove 2011, which helps more air flow to enter the heat dissipation from the first air inlet position 2012 and improves the heat dissipation effect.

[0057] Figure 10Three-dimensional view of the combination of the fan body 1 of the present utility model and the air-conditioning component 3. At this time, the air-conditioning component 2 is provided with second moving wheels 12, that is, the air-conditioning component 2 can also be moved and used through the second moving wheels 12. The housing 201 is also connected with a power cord 13. The access end of the power cord 13 is located in the assembly groove 2011 and the access end of the power cord 13 is located in the assembly groove 4. The assembly groove 4 functions to accommodate the power cord 13.

[0058] The structural feature of the combined new type of local refrigeration device of this air-conditioning fan is that through the organic combination of the fan body 1 and the air-conditioning component 2, the fan body generates a flowing air current, and the air-conditioning component 2 provides cold air. It is mainly aimed at cooling only the immediate range of people or objects in need in indoor, outdoor open spaces or a large indoor specific space environment, that is, cooling and lowering the temperature of a specific local area in need; the process of heat transfer is that through the air-conditioning component 2, the cold quantity in the area far from people or objects is transferred to the immediate range of people or objects, so as to achieve the purpose of targeted cooling.

[0059] This local refrigeration device does not need to consider "taking heat (cold) from the outside and transferring it indoors", but only needs to cool a specific range, and does not need to consider indoor-outdoor heat exchange. That is, the cold quantity in the far area is transferred to the immediate range of people or objects to achieve the purpose of cooling the target area.

[0060] This device creatively provides a solution for transportable, unrestricted by indoor and outdoor environments, unrestricted by installation positions, remotely directed cold air supply, and combined directional cooling.

[0061] This device can be productized, can be used by civilians to supply cold to local areas or the immediate range of people and objects, and can also be used industrially to supply cold to local areas in large spaces or field operation sites, including applications such as factories, squares, mining areas, tunnels, and building platforms. It can be transported by vehicle, can be used in combination and expanded, and can supply cold with increased power and air volume.

[0062] This device uses wheels for transport; uses a microporous spraying device (to solve the technical difficulties of the high temperature and high pressure on the condensation side of the refrigeration system) and environmental heat dissipation to jointly supply cold to a specified area or the immediate range of people and objects in the same space, without the need for indoor-outdoor isolation; uses an air duct to remotely direct cold air supply, can increase power and air volume, and can supply cold to large spaces, large areas, factories, and field operation sites to achieve local area cooling.

[0063] This device is characterized by the following: 1. There are no restrictions on the location and space isolation between indoor and outdoor environments, enabling the normal operation of the refrigeration system. An air conditioner needs to utilize indoor and outdoor air for energy transfer and heat exchange. However, it is limited by the energy transfer space of the indoor and outdoor environments. Otherwise, it is difficult for the system to operate stably due to excessive condensation temperature and pressure. This device uses a "condenser microporous spraying device" in combination with the refrigeration system and environmental heat dissipation to overcome the technical problem of excessive condensation temperature and pressure, enabling this refrigeration system to operate stably for cooling without the need for indoor-outdoor isolation. 2. This device is movable and not restricted by the installation location. The main unit of the refrigeration system, the fan, and the air duct can be transported combined or separately. 3. It can supply cold air through remote air supply. This device utilizes the fact that the main unit of the refrigeration system is movable and can increase power, the air duct is movable, can be lengthened and thickened, and the fan and blower are movable and can increase power, thereby achieving long-distance air supply for cooling. 4. This device can be used in large indoor spaces, outdoor open spaces, and field environments. It is movable and can adjust the direction of cold air supply, thereby realizing the function of directional cold air supply to a local area in the close range for people, groups, equipment and facilities, rooms or designated spaces, and field operation areas in need.

[0064] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
