Description

[Technical Field]

[0001] The present invention relates to the field of air conditioning technology, and in particular to a ductless mobile air conditioner. [Background technology]

[0002] Conventional mobile air conditioners typically use a vapor compression refrigeration cycle, primarily consisting of a compressor, condenser, throttle, and evaporator. The condenser typically uses an air-cooling mode for heat dissipation, which uses a built-in fan to force convection and directly expel the heat released during the condensation process to the surrounding environment. To ensure effective heat transfer, conventional mobile air conditioners must have an exhaust duct connected to the hot air outlet, which must extend to the outdoors or a dedicated heat exhaust passage to form a forced heat exhaust path.

[0003] The exhaust duct must be located next to a window or vent, or must be located along a reserved heat exhaust passage, preventing true freedom of movement as the indoor equipment layout changes. In large machine rooms or complex spaces, issues such as exhaust duct length limitations and piping path obstructions significantly restrict the usability and application range of mobile air conditioners, making it difficult to meet the actual needs for rapid deployment and multi-point rotation.

[0017] The following is a detailed description of the embodiments of the present invention. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are used only to explain the present invention, and cannot be interpreted as limitations on the present invention.

[0018] As shown in FIGS. 1 to 14, an embodiment of the present invention provides a ductless mobile air conditioner, which includes a case 10, a condenser 20, an evaporator 30, a water tank 40, and a water guide member 70.

[0019] The case 10 is provided with a storage chamber 11, which has a first air duct 12 and a second air duct 13. The first air duct 12 is mainly used for the heat dissipation process of the condenser 20, while the second air duct 13 is mainly used for the cooling process of the evaporator 30. This allows the air conditioner to route air between the condenser 20 and the evaporator 30 via two independent air ducts. The separate design of the first air duct 12 and the second air duct 13 allows for efficient air flow and prevents heat interference between the condenser 20 and the evaporator 30, improving the stability and efficiency of the air conditioner.

[0020] As shown in Figures 1 and 2, the case 10 includes a first side case surface 101, a second side case surface 102, a third side case surface 103, a fourth side case surface 104, and a top case surface 105, and the first side case surface 101, the second side case surface 102, the third side case surface 103, and the fourth side case surface 104 are side surfaces of the case 10, and the first side case surface 101, the second side case surface 102, the third side case surface 103, and the fourth side case surface 104 are located horizontally in the circumferential direction of the storage chamber 11. The first case surface 101 and the fourth case surface 104 are located between the second case surface 102 and the third case surface 103, the first case surface 101 and the fourth case surface 104 are installed opposite each other, the second case surface 102 and the third case surface 103 are located on both sides, and the top case surface 105 is located above the storage chamber 11 in the direction of gravity, and the top case surface 105 is located at the top of the case 10.

[0021] The first air duct 12 has a first air intake port 121 and a first air exhaust port 122. The first air duct 12 adopts a horizontal circulation mode of lateral intake and exhaust, where the first air intake port 121 is provided on the first case surface 101, the first air exhaust port 122 is provided on the second case surface 102 and / or the third case surface 103, and the first air exhaust port 122 is distributed on at least one of the second case surface 102 and the third case surface 103. In one possible embodiment, the first air exhaust port 122 is provided on the second case surface 102 or the third case surface 103 to form a one-sided exhaust, which can intensively guide heat in a specific direction.

[0022] The second air duct 13 has a second intake port 131 and a second exhaust port 132. The second air duct 13 adopts a vertical circulation mode with side intake and top exhaust, with the second intake port 131 located on the fourth side case surface 104 and the second exhaust port 132 located on the top case surface 105. Preferably, the second intake port 131 is also located on the second side case surface 102 to increase the return air area.

[0023] The condenser 20 is provided in the first air duct 12 and contains a refrigerant. The refrigerant is a medium for transferring heat in the air conditioning system, circulating within the air conditioning system and absorbing and releasing heat through phase transition. The condenser 20 includes a coiled tube, and the superheated gas discharged from the compressor releases heat as it advances through the coiled tube, and the refrigerant becomes a subcooled liquid when it reaches the outlet of the coiled tube.

[0024] In conventional air conditioning systems, heat dissipation from the condenser 20 is achieved by dissipating heat to the external environment via a fan. In contrast, in the embodiment of the present invention, heat dissipation from the condenser 20 is primarily achieved by heat exchange with a temperature-reducing liquid. The temperature of the temperature-reducing liquid is lower than the temperature of the refrigerant in the condenser 20, allowing it to more effectively absorb heat and improve heat dissipation efficiency. The heat exchange between the temperature-reducing liquid and the refrigerant in the condenser 20 prevents excess heat from being directly released into the external environment, reducing thermal pollution to the surrounding environment.

[0025] The evaporator 30 is provided in the second air duct 13, and its function is to absorb heat from the air to lower the temperature of the air and achieve a cooling effect. In the second air duct 13, the evaporator 30 exchanges heat with the air to absorb the heat from the air and lower the air temperature.

[0026] The water tank 40 is provided in the accommodation chamber 11 and has a water reservoir 41 for storing a temperature-reducing liquid. The temperature-reducing liquid may be water, and the temperature of the temperature-reducing liquid is lower than the temperature of the refrigerant in the condenser 20. The role of the water tank 40 is to supply low-temperature temperature-reducing liquid to the condenser 20. Since the temperature of the temperature-reducing liquid is lower than the temperature of the refrigerant in the condenser 20, the temperature-reducing liquid can absorb heat in the condenser 20 and achieve heat exchange. Preferably, the temperature-reducing liquid is circulatable, and the low-temperature temperature-reducing liquid is continuously supplied to the condenser 20 through a circulating flow.

[0027] The water guide member 70 is installed in the first air duct 12, and by drawing the temperature-reducing liquid to the condenser 20, heat exchange between the temperature-reducing liquid and the refrigerant is achieved, thereby lowering the temperature of the airflow at the first exhaust port 122 of the first air duct 12 to an appropriate temperature. Because the heat of the refrigerant is effectively absorbed by the temperature-reducing liquid rather than directly discharged in the form of hot air, the exhaust duct structure can be eliminated, and heat dissipation from the condenser 20 can be achieved through internal water circulation. Users can freely move the device to any location in the room according to their actual needs, thereby expanding usability and the range of applications.

[0028] 4 and 5, a base 14, a standing plate 15, a first fan unit 50, and a second fan unit 60 are provided within the accommodation chamber 11. The base 14 serves as a mounting platform, and the standing plate 15 serves as a vertical isolation structure, allowing the first air duct 12 and the second air duct 13 to be independent of each other and not interfere with each other. The first fan unit 50 is provided within the first air duct 12, and the second fan unit 60 is provided within the second air duct 13, thereby accelerating the flow of air within the first air duct 12 and the second air duct 13, forming a power source for forced convection and improving heat dissipation and cooling efficiency.

[0029] The standing plate 15 is fixed to the base 14 to form a substantially inverted T-shaped frame, and the first air duct 12 and the second air duct 13 are formed on opposite sides of the standing plate 15 in the horizontal direction. After the standing plate 15 is fixed vertically, the sides of the standing plate 15 naturally form two relatively independent spatial regions, providing a stable physical boundary for dividing the first air duct 12 and the second air duct 13 into regions.

[0030] The condenser 20 and the evaporator 30 are both fixed to the base 14, and are arranged on opposite sides of the standing plate 15 in the horizontal direction, and the first fan unit 50 and the second fan unit 60 are both fixed to the standing plate 15 by a suspension-type or embedded-type mounting method.

[0031] The first fan unit 50 is located between the condenser 20 and the standing plate 15. The condenser 20 is installed corresponding to the intake side of the first fan unit 50. The first fan unit 50 takes in air through the first intake port 121, forces the air through the condenser 20, and then discharges it through the first exhaust port 122, ensuring that condensation heat is sufficiently removed. The standing plate 15 plays a role in guiding the air and sealing it, preventing hot air from leaking to the evaporator 30.

[0032] The second fan unit 60 is located between the evaporator 30 and the standing plate 15. The evaporator 30 is provided corresponding to the intake side of the second fan unit 60. The second fan unit 60 takes in air from the second intake port 131 and generates cool air after forcibly passing the air through the evaporator 30. The standing plate 15 plays a role in guiding the air and sealing it, preventing the cool air from leaking to the condenser 20 side.

[0033] In an embodiment of the present application, as shown in FIGS. 4 and 5, the first fan unit 50 includes a first drive motor 51, a centrifugal wind turbine 52, and a centrifugal volute 53, in which the first drive motor 51 serves as a power source, the centrifugal wind turbine 52 serves as a working component, and the centrifugal volute 53 serves as a flow guide component.

[0034] The first drive motor 51 can be fixed to the standing plate 15 by a suspension-type or embedded mounting structure. The centrifugal wind turbine 52 is fixed to the output shaft of the first drive motor 51, and the first drive motor 51 constitutes the rotation drive means of the centrifugal wind turbine 52. The centrifugal volute 53 is installed between the condenser 20 and the standing plate 15 and encloses the entire cavity between the condenser 20 and the standing plate 15 in a sealed air duct. The centrifugal volute 53 and the condenser 20 together form an air intake chamber and ensure that air can only be drawn in through the fins of the condenser 20. The centrifugal volute 53 also directs the airflow blown out from the centrifugal wind turbine 52 to the first exhaust port 122, realizing concentrated use of the air volume.

[0035] 4 and 5, the centrifugal volute 53 has a first opening 531 and a second opening 532. The first opening 531 is provided corresponding to the intake side of the centrifugal wind turbine 52 and the condenser 20. The first opening 531 is responsible for drawing in airflow from the condenser 20 side. The second opening 532 is responsible for directing the pressurized airflow to the first exhaust port 122. The second opening 532 is provided corresponding to the exhaust side of the centrifugal wind turbine 52 and is aligned with the airflow blowing direction of the centrifugal wind turbine 52 to shorten the exhaust path and reduce exhaust resistance. The air heated by the condenser 20 is drawn directly into the center of the centrifugal wind turbine 52 through the first opening 531, then blown out in the radial direction of the centrifugal wind turbine 52, and then discharged through the second opening 532.

[0036] In the embodiment of the present application, the second fan unit 60 includes a second drive motor 61, a cross-flow wind turbine 62, and a cross-flow volute 63. The cross-flow wind turbine 62 is cylindrical, and the airflow enters along the axial direction and is blown out along the radial direction, forming a long, uniform air curtain.

[0037] The cross-flow volute 63 is fixed to the upright plate 15, the second drive motor 61 is fixed to the cross-flow volute 63, the second drive motor 61 and the wind turbine are arranged coaxially, the cross-flow wind turbine 62 is supported on the cross-flow volute 63, and the cross-flow wind turbine 62 is fixedly connected to the output shaft of the second drive motor 61, the second air intake port 131 and the second air exhaust port 132 are located on the outer periphery of the cross-flow wind turbine 62, indoor air is drawn in from the fourth side case surface 104, and a wide horizontal airflow can be formed on the top case surface 105 of the air conditioner, achieving uniform diffusion of cool air in the horizontal direction.

[0038] 4, a heat shield plate 17 and a blocking plate 18 are provided in the accommodation chamber 11. The heat shield plate 17 and the blocking plate 18 are both provided between the standing plate 15 and the evaporator 30 and located below the once-through volute 63. The heat shield plate 17 is connected to the standing plate 15 and the blocking plate 18, and the blocking plate 18 is connected to the heat shield plate 17 and the evaporator 30. The heat shield plate 17 is made of a low thermal conductivity material and serves to block heat transfer, preventing heat from the condensation side from radiating to the evaporation side through the standing plate 15. The blocking plate 18 serves to block airflow leakage, allowing most of the intake air of the second air duct 13 to enter from the axial direction of the once-through wind turbine 62, thereby improving the effective heat exchange area and heat exchange efficiency of the evaporator 30.

[0039] 4, the axis of the centrifugal wind turbine 52 is perpendicular to that of the cross-flow wind turbine 62, and the rotation axis of the centrifugal wind turbine 52 and the rotation axis of the cross-flow wind turbine 62 are perpendicular to each other in space, thereby realizing a compact air conditioner structure and reducing the space occupied by the air conditioner. The axis of the centrifugal wind turbine 52 extends along the horizontal longitudinal direction (perpendicular to the standing board 15), and the centrifugal wind turbine 52 takes in air vertically and exhausts air horizontally, driving the airflow to be discharged from the condenser 20 side to the second case surface 102 or the third case surface 103 in the horizontal plane. The cross-flow wind turbine 62 takes in air laterally and exhausts air circumferentially, and the axis of the cross-flow wind turbine 62 extends along the horizontal lateral direction (perpendicular to the second side case surface 102 and the third side case surface 103), driving the airflow upward in a vertical plane and exhausting it from the top case surface 105.

[0040] In an embodiment of the present application, the extension direction of the top case surface 105 and the horizontal direction form an included angle of 15° to 45°, and the included angle is preferably 22.5°. When the extension direction of the top case surface 105 is smaller than the minimum value of the predetermined range, the exhaust airflow is too horizontal and cannot cover a long-distance space. When the extension direction of the top case surface 105 is larger than the maximum value of the predetermined range, the exhaust airflow rises in a concentrated manner. When the extension direction of the top case surface 105 is within the predetermined range, the exhaust airflow is projected obliquely upward, covering a wide area, and the wind speed can be within a comfortable range sensed by the human body.

[0041] In an embodiment of the present application, the ductless mobile air conditioner further includes at least one ice box, which is installed in the water storage chamber 41 and is used to reduce the temperature of the temperature reducing liquid by exchanging heat with the temperature reducing liquid.

[0042] The ice box is a cold source, or regenerator, and is a flat rectangular parallelepiped. The ice box is installed as a complete module within the water tank 40, allowing it to be easily removed and replaced, facilitating replacement and maintenance. Most of the ice box is immersed in the temperature-reducing liquid in the water tank 40, providing a uniform and continuous cooling effect. It continuously removes heat from the temperature-reducing liquid, lowering the temperature of the temperature-reducing liquid until it stabilizes at a design value. This design value is lower than the temperature of the refrigerant in the condenser 20. This ensures that the heat released from the refrigerant during the condensation process is quickly and effectively removed by the temperature-reducing liquid. The number of ice boxes can be increased or decreased depending on the demand for cooling, and operation can continue even if one ice box is disabled.

[0043] The ice box contains low-temperature phase-change ice as a refrigerant, which exchanges heat with the temperature-reducing liquid to reduce the temperature of the liquid. The temperature-reducing liquid absorbs heat from the refrigerant in the condenser 20 and then transfers the heat to the outer wall of the ice box. The low-temperature phase-change ice in the ice box absorbs the heat and provides and maintains the low temperature of the temperature-reducing liquid.

[0044] The low-temperature phase-transition ice exists in the form of solid ice inside the ice box. As the ice box continues to absorb heat from the water tank 40, the low-temperature phase-transition ice gradually changes from solid to liquid. Although the ice exchanges a large amount of latent heat during the solid-liquid phase transition process, its own temperature remains nearly constant, so the outer wall of the ice box can maintain a low temperature for a long period of time, providing a stable cold end to the temperature-reducing liquid, which keeps the temperature of the temperature-reducing liquid lower than the temperature of the refrigerant in the condenser 20.

[0045] As shown in Figure 6, a water tank 141 is provided within the base 14, and the water tank 141 is a cavity recessed downward from the top surface of the base 14 or a tank body surrounded by several protrusions. The temperature-reducing liquid in the water tank 40 passes through the water tank 141, and the heat of the condenser 20 is first transferred to the temperature-reducing liquid. The liquid dripping from the condenser 20 also falls directly into the water tank 141, preventing water from accumulating within the case 10 and enabling the temperature-reducing liquid to be recycled.

[0046] The water guide member 70 is positioned above the water tank 141 to guide at least a portion of the temperature-reducing liquid on the water tank 141 to the condenser 20. As shown in FIGS. 7 and 8, in this embodiment of the present invention, the water guide member 70 includes a third drive motor 71 and a rotating disk 72 that is power-transmitted to the output shaft of the third drive motor 71. The third drive motor 71 is fixed to the base 14, and the output shaft of the third drive motor 71 extends horizontally above the water tank 141. The rotating disk 72 is power-transmitted to the output shaft of the third drive motor 71 as a rotating body and rotates synchronously with the motor. The body of the third drive motor 71 is enclosed in a sealed cover to prevent short circuits caused by splashing of the temperature-reducing liquid.

[0047] A plurality of blades 73 are provided on the outer periphery of the turntable 72, and the blades 73 are arranged at intervals in an annular pattern around the axis of the turntable 72. The blades 73 are radially or backwardly curved and uniformly distributed around the periphery of the turntable 72 to form a symmetrical rotating mass and ensure dynamic balance. Spaces are left between adjacent blades 73, allowing the temperature-reducing liquid to rise at the moment of rotation, and the temperature-reducing liquid naturally returns to the water tank 141 after being lifted, completing efficient heat exchange while preventing the liquid from splashing outside the case 10 and keeping the interior dry and clean.

[0048] The third drive motor 71 provides continuous rotational power to drive the rotating disk 72 in a circular motion. As the rotating disk 72 rotates, the blades 73 lift the temperature-reducing liquid in the water tank 141, and the temperature-reducing liquid is blown out tangentially under the action of centrifugal force to form an annular liquid curtain. The liquid curtain directly impinges on the condenser 20, achieving uniform coverage. The thin and uniform liquid film enhances heat exchange efficiency.

[0049] As shown in Figure 9, a through-hole 42 is formed in the water tank 40, and the through-hole 42 connects the water storage chamber 41 to the outside. The through-hole 42 is a through-hole formed in the wall of the water tank 40, and connects the internal water storage chamber 41 directly to the outside. The through-hole 42 serves as an outlet for the outflow of temperature-reducing liquid and provides mounting positioning for the subsequent water nozzle 43.

[0050] A water nozzle 43 is provided in the through-hole 42, and one end of the water nozzle 43 extends from the water tank 40. The water nozzle 43 is a rigid or semi-rigid pipe member, and both ends thereof extend into the water storage chamber 41 and outside the water storage chamber 41, respectively. The end extending into the water storage chamber 41 serves as a fitting port for an internal water pipe, and the end extending outside the water tank 40 can be connected to the adapter member 161 of the adapter base 16.

[0051] One end of the water pipe is connected to the first end of the water nozzle 43 by a seal or integral molding, and the other end of the water pipe is freely suspended. During water extraction, the negative pressure generated by the water pump passes through the adapter member 161 and the water nozzle 43 in order to reach the water pipe, and continues to suck out the temperature-reducing liquid in the water storage chamber 41.

[0052] As shown in Figures 5 and 6, the ductless mobile air conditioner further includes an adapter base 16, with the adapter base 16 and the water tank 40 both located below the base 14. The adapter base 16 and the base 14 are preferably integrally molded, with the adapter base 16 and the water tank 40 installed horizontally opposite each other. The adapter base 16 is provided with an adapter member 161, which is fixed to the adapter base 16 by snap-fit, screws, or quick-insertion. The adapter member 161 has a hollow interior with a temperature-reducing liquid passage formed therein. The adapter member 161 is connected to a pipeline, which is directly inserted into the adapter member 161 and can be locked with quick-insertion, clips, or screws.

[0053] The adapter member 161 contains a check valve 162, which is removably connected to the water nozzle 43. The outer diameter of the water nozzle 43 fits into the port of the check valve 162, allowing it to be connected by straight insertion into the check valve 162. The check valve 162 is a one-way valve that opens when pressure is applied in the forward direction and immediately closes when pressure is applied in the reverse direction. When the water nozzle 43 is connected to the check valve 162, the check valve 162 only allows the temperature-reducing liquid in the water reservoir 41 to flow sequentially through the water pipe, water nozzle 43, check valve 162, and adapter member 161, and then into the water tank 141.

[0054] When the water pump in the air conditioner is running, the check valve 162 is pushed open by the water flow, allowing the water in the water tank 40 to smoothly enter the pipeline. When the user extracts or moves the water tank 40, the connection between the check valve 162 and the pipeline is cut off, and the check valve 162 immediately closes, preventing the temperature-reducing liquid in the water tank 40 from leaking out. When the pressure in the pipeline fluctuates, the check valve 162 also prevents the temperature-reducing liquid from entering the water tank 40 in the reverse direction.

[0055] In the embodiment of the present application, the check valve 162 is made of an elastic material, and the entire check valve 162, or at least the valve body portion thereof, is integrally molded from an elastic polymer material such as silica gel, EPDM, TPE, etc. This forms a surface seal with the water nozzle 43, and the check valve 162 opens and closes by utilizing the elastic recovery force of the material itself.

[0056] As shown in FIGS. 12 and 14 , a flow path 1621 is provided within the check valve 162. The flow path 1621 is a through-passage formed within the check valve 162. The flow path 1621 has a first end (inlet) and a second end (outlet), and serves as a path for the temperature-reducing liquid to enter the check valve 162 from the water nozzle 43. The water nozzle 43 extends into the flow path 1621 from its first end. In one possible embodiment, the outer diameter of the second end of the water nozzle 43 is slightly larger than the inner diameter of the first end of the flow path 1621, forming an interference fit. After the water nozzle 43 is inserted, the check valve 162 opens radially, generating uniform containment pressure. The outer wall of the water nozzle 43 and the inner wall of the flow path 1621 form a surface-contact seal, eliminating the need for an additional O-shaped sealing ring and avoiding the risk of leakage due to sealing ring aging or misalignment.

[0057] As shown in Figure 14, the second end of flow path 1621 forms slit-shaped opening 1622, which is a linear slit (duckbill or straight line) formed by the natural joining of two elastic lip edges. During the water extraction phase, when negative pressure from the water pump acts on the outside of slit-shaped opening 1622, the lip edges are sucked, expanding slit-shaped opening 1622 into a roughly elliptical hole, allowing the temperature-reducing liquid to flow out smoothly. When the air conditioner is stopped, the lip edges immediately close under the action of the material's elasticity and external atmospheric pressure, causing the slit width to approach zero and achieving instantaneous sealing.

[0058] In one possible embodiment, as shown in Figures 12 and 14, the check valve 162 has a radially contracted region in which the walls on both sides of the flow passage 1621 gradually contract along the length of the flow passage 1621 to form a sloped surface 1623, with a slit-shaped opening 1622 formed at the end of the sloped surface 1623. The check valve 162 forms an elastic lip edge due to a gradation in wall thickness during the radially contracted region, and from the beginning to the end of the contracted region, the inner wall of the flow passage 1621 exhibits a symmetrical slope, with the cross-section gradually transitioning from a circular shape to an elongated slit. During water extraction, the walls on both sides of the sloped surface 1623 gradually expand outward due to the negative pressure, and the cross-sectional area of ​​the flow passage 1621 gradually expands along the slope, reducing flow resistance. When stopped, the slope surface 1623 quickly closes due to elastic rebound, generating a wedge-type self-lock, realizing zero leakage at low pressure difference and improving sealing reliability.
