Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to a mobile air conditioner. Background Art

[0002] A mobile air conditioner belongs to a type of integral air conditioner. The evaporator and the condenser are installed in the same space. When operating under a refrigeration condition, condensed water will inevitably be generated on the evaporating fins. Affected by gravity, the condensed water is finally collected in a water collecting tank at the bottom of the air conditioner and ultimately requires manual drainage. Almost all mobile air conditioners are provided with a condensed water self-evaporation system. The principle is to atomize the condensed water by using the centrifugal force generated by high-speed rotation. The main working process is as follows: The motor drives a water pumping wheel to break and atomize the condensed water and then sprinkle it on the condenser fins (at a high temperature). The atomized water droplets absorb heat, evaporate, and are discharged outdoors through an exhaust duct.

[0003] Restricted by the installation position of the water pumping wheel and its structural design, the atomized condensed water cannot be evenly distributed in the high-temperature space on the condenser side, and there is a certain atomization dead zone, which results in a reduction in the evaporation amount of the condensed water and insufficient utilization of the condensation heat. Especially in high-humidity areas, the production of condensed water is large, and through this condensed water self-evaporation system, the condensed water cannot be evaporated and discharged in time, thus bringing the trouble of manual drainage.

[0004] In the related art, the rotation speed of the water pumping wheel is fixed and cannot be adjusted according to the amount of condensed water. The atomization rate is the same under different water amounts, which will cause insufficient atomization ability at a higher water amount. The mobile air conditioner has the disadvantages of an atomization dead zone, a lower evaporation rate of condensed water, inability to fully utilize the condensation heat, and a fixed rotation speed of the water pumping wheel. When the system operates under a high-humidity condition, the condensed water cannot be quickly evaporated through the water pumping component, and the problem of shutdown due to water fullness will still occur, and manual drainage is required.

Detailed description of the specific implementation

[0033] The following details the embodiments of the present invention. The embodiments described with reference to the drawings are exemplary. The following details the embodiments of the present invention.

[0034] The following refers to Figures 1 - 11 Describe a mobile air conditioner according to an embodiment of the present invention.

[0035] Combined with Figure 1As shown in the figure, the mobile air conditioner includes: a refrigerant circuit, an outdoor unit part, and an indoor unit part. In the refrigerant circuit, the refrigerant circulates successively through a compressor, a condenser, a decompressor, and an evaporator. One of the condenser and the evaporator is the outdoor heat exchanger 12, and the other is the indoor heat exchanger.

[0036] The outdoor unit part is located on the lower side. The outdoor unit part includes a first housing, an outdoor fan, a compressor, and the outdoor heat exchanger 12 arranged in the first housing. A water collecting tank 11 is formed at the bottom of the outdoor unit part. When the outdoor heat exchanger 12 serves as an evaporator, condensed water is generated at the evaporator, and the condensed water gathers in the water collecting tank 11 to prevent the condensed water from corroding components.

[0037] An outdoor air inlet and an outdoor air outlet are provided on the first housing. Outdoor air enters the first housing from the outdoor air inlet and then exits the outdoor from the outdoor air outlet. The compressor, the outdoor heat exchanger 12, and the outdoor fan are all arranged in the first housing. Outdoor air enters the first housing from the outdoor air inlet, exchanges heat inside the first housing, and then exits the outdoor from the outdoor air outlet.

[0038] The compressor is arranged inside the first housing. The compressor is provided with an exhaust port and a suction port. The compressor compresses the refrigerant, turning the low-pressure refrigerant into a high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor from the suction port. After the compressor compresses the low-pressure refrigerant into a high-pressure refrigerant, the high-pressure refrigerant exits from the exhaust port. The refrigerant releases heat at the condenser, absorbs heat at the evaporator after decompression, and finally enters the compressor from the suction port.

[0039] The outdoor heat exchanger 12 is arranged inside the first housing to exchange heat between the outdoor air and the refrigerant flowing in the outdoor heat exchanger 12. The outdoor air entering the inside of the first housing from the outdoor air inlet flows to the outdoor heat exchanger 12 to exchange heat with the refrigerant. The outdoor air enters the first housing from the outdoor air inlet and flows to the outdoor heat exchanger 12; and the refrigerant flows in the outdoor heat exchanger 12. When the outdoor air passes through the outdoor heat exchanger 12, it exchanges heat with the refrigerant; the heated outdoor air then flows to the outdoor air outlet and is discharged outdoors from the outdoor air outlet.

[0040] For example, the outdoor heat exchanger 12 operates as a condenser in the cooling mode of the mobile air conditioner, enabling the refrigerant compressed by the compressor to release heat to the outdoor air through the outdoor heat exchanger 12 and condense. The outdoor heat exchanger 12 operates as an evaporator in the heating mode of the mobile air conditioner, enabling the decompressed refrigerant to absorb the heat of the outdoor air through the outdoor heat exchanger 12 and evaporate.

[0041] The outdoor fan is located inside the first housing. Driven by the outdoor fan, outdoor air enters the first housing from the outdoor air inlet, flows to the outdoor heat exchanger 12, and after the outdoor air exchanges heat with the refrigerant at the outdoor heat exchanger 12, the refrigerant is discharged outdoors from the outdoor air outlet driven by the outdoor fan.

[0042] The indoor unit is located above the outdoor unit. The indoor unit includes a second housing, and an indoor air duct member, an indoor fan, and an indoor heat exchanger disposed in the second housing. The indoor fan is disposed within the indoor air duct member.

[0043] The second housing is located above the first housing, and the first housing and the second housing are connected. That is, an indoor air inlet and an indoor air outlet are provided on the second housing. Indoor air enters the second housing through the indoor air inlet and then enters the room through the indoor air outlet. The indoor heat exchanger, the indoor fan, and the indoor air duct member are located within the second housing. Indoor air enters the second housing, exchanges heat at the indoor heat exchanger, and then enters the room through the indoor air outlet.

[0044] The indoor heat exchanger is disposed within the second housing to exchange heat between the indoor air and the refrigerant flowing through the indoor heat exchanger. The indoor air entering the second housing through the indoor air inlet flows to the indoor heat exchanger to exchange heat with the refrigerant. The indoor air enters the second housing through the indoor air inlet and flows to the indoor heat exchanger; the refrigerant flows through the indoor heat exchanger. When the indoor air passes through the indoor heat exchanger, it exchanges heat with the refrigerant; the heat-exchanged indoor air then flows to the indoor air outlet and is discharged into the room through the indoor air outlet.

[0045] For example, the indoor heat exchanger operates as an evaporator in the cooling mode of the mobile air conditioner, such that the depressurized refrigerant absorbs the heat of the indoor air through the indoor heat exchanger and evaporates. The indoor heat exchanger operates as a condenser in the heating mode of the mobile air conditioner, such that the refrigerant compressed by the compressor dissipates heat to the indoor air through the indoor heat exchanger and condenses.

[0046] The indoor fan is disposed within the indoor air duct member. The indoor fan rotates to drive the air flow to enter the second housing through the indoor air inlet, exchange heat with the indoor heat exchanger, and then flow to the room through the indoor air outlet. Driven by the indoor fan, the indoor air enters the second housing through the indoor air inlet, flows to the indoor heat exchanger. After the indoor air exchanges heat with the refrigerant at the indoor heat exchanger, the refrigerant is discharged into the room through the indoor air outlet under the drive of the indoor fan.

[0047] Combined Figures 1 - 10 As shown, the mobile air conditioner further includes a water spraying assembly. The water spraying assembly is disposed within the outdoor unit. The water spraying assembly includes a driving member, a rotating shaft 21, a water pump, and an atomizing member 23. The driving member is disposed at the bottom of the outdoor unit; the rotating shaft 21 is in transmission connection with the driving member; the water pump is disposed within the water collecting tank 11; at least a part of the atomizing member 23 is disposed within the water collecting tank 11, and the atomizing member 23 is in transmission connection with the rotating shaft 21.

[0048] The driving member is in transmission connection with the rotating shaft 21, and the rotating shaft 21 is in transmission connection with the atomizing member 23. When the driving member drives the rotating shaft 21 to rotate, the atomizing member 23 rotates with the rotating shaft 21. At least a part of the atomizing member 23 is arranged in the water collecting tank 11. During the rotation of the atomizing member 23, more condensed water can be lifted and quickly broken and atomized.

[0049] When the condensed water level is lower than the critical water level, the driving member starts, and the atomizing holes 234 break the condensed water into water mist. That is to say, when the condensed water in the water collecting tank 11 is lower than the critical water level, the driving member drives the rotating shaft 21 to rotate to atomize the condensed water. At this time, the atomizing method is centrifugal atomization.

[0050] When the water level is higher than the critical water level, the driving member stops operating, and the condensed water is pumped into the atomizing member 23 by a water pump, and a water column is ejected from the atomizing member 23. During the ejection of the condensed water, the rotating shaft 21 can be driven to rotate by the centrifugal force and reaction force of the water flow, so as to realize multi-directional water spraying and atomization. In the above process, when the fine and high-speed jet ejected from the atomizing member 23 impacts the wall surface of the nearby atomizing member 23, secondary fragmentation and atomization will occur. The atomizing methods involved in this process include centrifugal atomization and jet impact atomization.

[0051] As Figure 4 、 Figure 5 and Figure 7 shown, the atomizing member 23 is provided with a plurality of atomizing regions 231 in the circumferential direction. Any one atomizing region 231 includes: a spray hole 233 and a plurality of atomizing holes 234. The spray hole 233 is arranged at a position close to the center of the atomizing member 23 in the atomizing region 231, and the plurality of atomizing holes 234 are arranged at a position close to the edge of the atomizing member 23 in the atomizing region 231.

[0052] The high-speed rotational movement of the atomizing region 231 can play a role in centrifugally atomizing the condensed water. Any one atomizing region 231 is provided with atomizing holes 234. The shape of the atomizing holes 234 is "wheel-shaped", including a plurality of tooth tips. The bending direction of the tooth tips is the same as the rotation direction of the rotating shaft 21. The arrangement of the wheel-shaped atomizing holes 234 can ensure that more condensed water is atomized.

[0053] The atomizing region 231 is provided with spray holes 233 for quickly ejecting and atomizing the condensed water. The atomizing holes 234 can lift and atomize the condensed water, so as to reduce the atomization dead zone, improve the atomization effect of the condensed water and increase its atomization rate, and achieve the purpose of drainage-free operation of the mobile air conditioner in a high-humidity environment. When the amount of condensed water is large, the method of atomizing the condensed water through the spray holes 233 can obtain a better atomization effect, the water mist is finer, and at the same time, the ejected water mist presents a fan shape, which can increase the coverage area of the water mist and reduce the atomization dead zone.

[0054] As Figures 4 - 7As shown, the water fetching assembly further includes: a water inlet pipe 22, which is coaxially placed with the rotating shaft 21. One end of the water inlet pipe 22 is connected to a water pump, and the other end of the water inlet pipe 22 is connected to one end of a plurality of water inlet branch pipes 221. The other ends of the plurality of water inlet branch pipes 221 are respectively communicated with a plurality of spray holes 233, dividing the condensed water into a plurality of tributaries. The plurality of tributaries are respectively communicated with the plurality of spray holes 233, and finally flow out from the spray holes 233.

[0055] When the condensed water level is higher than the critical water level, the water pump starts, and the spray holes 233 spray out the condensed water to atomize the condensed water. When the water level is higher than the critical water level, the driving member stops operating, and the condensed water is pumped into the atomizing member 23 by the water pump and ejected from the spray holes 233. During the process of spraying the condensed water, the rotation of the rotating shaft 21 can be driven by the centrifugal force and reaction force of the water flow, so as to realize multi-directional spraying and atomization. In the above process, when the fine and high-speed jet flow ejected from the spray holes 233 impacts the wall surface of the nearby atomizing member 23, secondary fragmentation and atomization will occur. The atomization methods involved in this process include centrifugal atomization and jet impact atomization.

[0056] When the condensed water level is lower than the critical water level, the driving member starts, and the atomizing holes 234 break the condensed water into water mist. That is to say, when the condensed water in the water collecting tank 11 is lower than the critical water level, the rotating shaft 21 is driven to rotate by the driving member to atomize the condensed water. At this time, the atomization method is centrifugal atomization.

[0057] Thus, when the condensed water is lower than the critical water level, the rotating shaft 21 is driven to rotate by the driving member to atomize the condensed water. At this time, the atomization method is centrifugal atomization; when the condensed water level is higher than the critical water level, the water pump starts, and the spray holes 233 spray out the condensed water to atomize the condensed water, and the ejection of the condensed water can drive the rotation of the rotating shaft 21, realizing the combination of centrifugal atomization and jet impact atomization.

[0058] In some embodiments, before the rotating shaft 21 operates, a condensed water filter (or a filter screen is directly installed) should be installed between the water pump and the water inlet of the atomizing member 23 to filter impurities in the condensed water and prevent the spray holes 233 from being blocked. A filter screen is installed at the inlet of the filter.

[0059] Preferably, the filter screen is larger than 100 mesh to ensure a certain filtering effect.

[0060] Such as Figure 4 and Figure 5As shown in the figure, the atomizing member 23 includes: a plurality of atomizing fan blades 232, the atomizing fan blades 232 protrude relative to the atomizing member 23, an atomizing area 231 is formed between two adjacent atomizing fan blades 232, and the spray holes 233 and the atomizing fan blades 232 are arranged oppositely. Specifically, the atomizing fan blades 232 serve to increase the amount of splashed condensed water and quickly break the condensed water. There is an atomizing area 231 between two adjacent atomizing fan blades 232. On the one hand, it can fix the two adjacent atomizing fan blades 232. On the other hand, a plurality of atomizing holes 234 are provided on the atomizing area 231, so that the high-speed rotational movement of the atomizing area 231 can play a role in centrifugally atomizing the condensed water.

[0061] Furthermore, the atomizing fan blades 232 are arc-shaped, and the bending direction of the atomizing fan blades 232 is consistent with the rotation direction of the atomizing member 23. Therefore, the water mist ejected from the spray holes 233 presents a fan shape, which can increase the coverage area of the water mist and reduce the atomizing dead zone.

[0062] When the water flow ejects along the spray holes 233, it will hit the outer curved side surface of the adjacent atomizing fan blade 232, and the impact point is approximately in the middle of the outer curved side surface. The reflection thrust generated by the water jet ejected at high speed from the spray holes 233 on the atomizing fan blade 232 can drive the rotating shaft 21 to rotate automatically. Therefore, when the fine and high-speed jet ejected from the spray holes 233 hits the nearby wall surface, secondary fragmentation atomization will occur. The atomization methods involved in this process include centrifugal atomization and jet impact atomization, realizing the combination of centrifugal atomization and jet impact atomization, improving the atomization effect of the condensed water and enhancing its atomization rate, and achieving the purpose of drainage-free for the mobile air conditioner in a high-humidity environment.

[0063] As Figure 7 and Figure 9 shown in the figure, a plurality of atomizing teeth 235 are provided on at least one side of the atomizing fan blade 232. The plurality of atomizing teeth 235 are arranged at intervals on the atomizing fan blade 232, and the atomizing teeth 235 are inclined towards the spray holes 233. By providing the atomizing teeth 235 on the atomizing fan blade 232, the atomizing fan blade 232 can raise more condensed water and quickly break and atomize it. When the amount of condensed water is large, the method of atomizing the condensed water through the spray holes 233 can obtain a better atomization effect, the water mist is finer, and at the same time, the ejected water mist presents a fan shape, which can increase the coverage area of the water mist and reduce the atomizing dead zone.

[0064] In some embodiments, the thickness of the atomizing fan blade 232 is h1, and h1 satisfies the relational expression: 2.5 mm ≤ h1 ≤ 3.5 mm; that is to say, the thickness of the atomizing fan blade 232 is between 2.5 mm and 3.5 mm, ensuring the structural stability of the atomizing fan blade 232. If the thickness of the atomizing fan blade 232 is less than 2.5 mm, the atomizing fan blade 232 is too thin and is prone to deformation due to the resistance of the condensed water during rotation, affecting the atomizing efficiency of the atomizing member 23; if the thickness of the atomizing fan blade 232 is greater than 3.5 mm, the atomizing fan blade 232 is too thick, the rotation resistance increases, and the atomizing efficiency of the atomizing member 23 is affected.

[0065] As Figure 9 shown, the central angle corresponding to two adjacent atomizing fan blades 232 is θ, and θ satisfies the relational expression: 45° ≤ θ ≤ 90°. With such a design, through the number of the atomizing fan blades 232, the contact area between the atomizing fan blades 232 and the condensed water per unit time is ensured, and the atomizing efficiency of the condensed water is improved.

[0066] Moreover, the outer diameter of the atomizing fan blade 232 is r1, the inner diameter of the atomizing fan blade 232 is r2, and r1 and r2 satisfy the relational expression: 3 mm ≤ r1 - r2 ≤ 6 mm. That is, the outer curved surface of the atomizing fan blade 232 is an arc with a radius of r1, the inner curved surface of the atomizing fan blade 232 is an arc with a radius of r2, and the difference range between the radius of the outer curved surface of the atomizing fan blade 232 and the radius of the inner curved surface of the atomizing fan blade 232 is between 3 mm and 6 mm.

[0067] Furthermore, the outer curved surface and the inner curved surface of the atomizing fan blade 232 are concentric circles.

[0068] As Figure 8 shown, the spray hole 233 is oval, and an atomizing groove 236 is arranged in the vertical direction of the spray hole 233. Specifically, there is an oval groove in the vertical direction at the outlet position of the spray hole 233, aiming to secondarily break the jet ejected from the spray hole 233 into a fan-shaped atomizing surface, so as to increase the atomizing area and reduce the atomizing dead zone.

[0069] As Figure 10 shown, the atomizing hole 234 includes: a main hole 237 and a plurality of sub-holes 238. The plurality of sub-holes 238 are circumferentially spaced on the main hole 237. The sub-holes 238 are composed of a first circle and a second circle. The first circle and the second circle are internally tangent to each other and the first circle is externally tangent to the main hole 237. Specifically, the shape of the atomizing hole 234 is a fire tooth shape. The main hole 237 forms the center of the fire tooth, and the plurality of sub-holes 238 form the fire tooth tips. The plurality of sub-holes 238 are circumferentially spaced around the main hole 237. The first circle and the second circle are internally tangent to each other and the first circle is externally tangent to the main hole 237 to form, then the sub-holes 238 include two arc surfaces, that is, a first arc surface and a second arc surface.

[0070] According toFigure 10 As shown, the radius of the main hole 237 is r3, and r3 satisfies the relation: 4mm ≤ r3 ≤ 8mm; and, the radius of the first circle is r4, and r4 satisfies the relation: 3mm ≤ r4 ≤ 6mm; and, the radius of the second circle is r5, and r5 satisfies the relation: 2mm ≤ r5 ≤ 4mm. That is to say, the radius range of the first arc surface is between 3mm and 6mm, the radius of the second arc surface is between 2mm and 4mm, the radius range of the main hole 237 is between 4mm and 8mm. One end of the first arc surface is tangent to one end of the second arc surface, the other end of the first arc surface is tangent to the main hole 237, and the other end of the second arc surface is tangent to the main hole 237, thereby forming the atomizing hole 234. Such a setting can ensure that more condensed water is atomized.

[0071] In addition, the mobile air conditioner further includes: a water level sensor, which is arranged in the water collecting tank 11 and electrically connected to the driving member and the water pump to selectively control the driving member or the water pump to start. That is to say, the water level sensor is divided into a critical water level sensor and a maximum water level sensor. The critical water level sensor is used to judge whether the condensed water level reaches the critical water level, so as to control the start and stop of the driving member and the water pump; the maximum water level sensor is used to monitor whether the water level in the water collecting tank 11 reaches the full water state to prevent the water collecting tank 11 from overflowing.

[0072] Among them, the setting of the critical water level needs to be based on the volume of the water collecting tank 11 and the flow rate of the water pump. The ultimate goal is to ensure that a better spraying state can be achieved after the water pump starts.

[0073] Refer to Figure 6 As shown, the mobile air conditioner further includes: a pressure sensor 13, which is arranged at the spray hole 233 and used to monitor the pressure of the water inside the spray hole 233. Specifically, the pressure sensor 13 is located inside the atomizing member 23 and is used to monitor the pressure of the water inside the atomizing member 23 to judge whether the pressure of the water inside the current atomizing member 23 can drive the atomizing fan blade 232 to rotate quickly, and to ensure that a better spraying effect can be achieved.

[0074] Refer to Figure 11As shown, when the water level of the condensed water is lower than the critical water level, the rotation speed of the rotating shaft 21 is controlled by the value measured by the air temperature and humidity monitoring points arranged on the exhaust duct. When the exhaust air temperature is lower than the preset temperature value / the exhaust humidity is higher than the preset humidity value, the evaporation amount of the condensed water is appropriate, and the driving member rotates at a low speed; otherwise, the driving member rotates at a high speed. When the condensation water level is higher than the critical water level, the driving member stops rotating, and the water pump pumps water. At this time, the atomizing member 23 sprays and atomizes, and rotates by means of the thrust of the water jet. Centrifugal atomization is used as an additional means. When the water pressure in the water collection tank 11 is lower than the preset pressure value, it indicates that the amount of condensed water in the water collection tank 11 is relatively low at this time and no more pumping is required. At this time, the water pump stops, and the motor starts to operate. If the water level is higher than the highest water level during the above process, the mobile air conditioner stops working.

[0075] When the water level is higher than the critical water level, the motor stops running, and the condensed water is pumped into the atomizing member 23 by the water pump and ejected from the spray holes 233. During the ejection of the condensed water, the atomizing member 23 can be driven to rotate by the centrifugal force and reaction force of the water flow, so as to realize multi-directional spraying and atomization. During the above process, when the fine and high-speed water jet ejected from the spray holes 233 impacts the nearby wall surface, secondary fragmentation and atomization will occur. The atomization methods involved in this process include centrifugal atomization and jet impact atomization.

[0076] In some embodiments, the outdoor heat exchanger 12 includes at least two sub-heat exchangers, and the atomizing member 23 is at least one, and the atomizing member 23 is clamped between two adjacent sub-heat exchangers. When the atomizing member 23 is arranged between two adjacent sub-heat exchangers, the spray generated by the atomizing member 23 can be carried away by the air around the sub-heat exchanger, so as to achieve the purpose of discharging the condensed water.
