Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioner technology, and more specifically, to a portable air conditioner. Background Technology
[0002] Portable air conditioners are small in size and have a compact internal structure. The distance between the air outlet and the air inlet is relatively close. After the air enters the air inlet, the airflow is accelerated by the rotation of the fan, and the airflow direction is changed by the air duct structure such as the volute before being discharged from the air outlet. However, after the airflow enters the portable air conditioner, the heat exchange effect of the evaporator and condenser is not ideal, resulting in uniform airflow at the air outlet but failing to guarantee the air outlet temperature. Summary of the Invention
[0003] The problem solved by this invention is that the air volume at the air outlet is uniform, but the air outlet temperature has a large deviation.
[0004] To address the aforementioned problems, this invention provides a portable air conditioner, comprising an air outlet assembly and a condenser assembly, the air outlet assembly and the condenser assembly being connected together. The air outlet assembly includes: a front panel with a first air inlet and a first air outlet, the first air inlet being connected to a first fan; a volute, connected to the front panel, the volute housing containing the first fan, the volute housing including: a first housing, the first fan being located inside the first housing, the first housing having a protrusion, the inner wall of the protrusion forming an airflow acceleration surface; and a connecting portion, connected to the first air outlet, forming an air outlet channel between the first fan and the connecting portion. After the fan drives the air to rotate, the air is accelerated through the protrusion and enters the air outlet channel; the evaporator is fixedly connected to the volute and is located between the volute and the front panel; the condenser assembly includes: a second housing, on which a second air inlet and a second air outlet are provided, the second air outlet communicating with the second air inlet; a condensing heat exchanger, which is connected to the evaporator, the condensing heat exchanger is inclined and located between the second air outlet and the second air inlet, and a receiving cavity is formed between the condensing heat exchanger and the second air inlet; wherein, the receiving cavity includes an air inlet buffer space and an air inlet receiving space, the air inlet buffer space being located on the side of the receiving cavity away from the condensing heat exchanger.
[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: The front panel and volute configuration enable the air outlet assembly to perform both air intake and exhaust functions; the first fan allows outside air to be drawn into the first housing; the protruding part further accelerates the airflow after the first fan rotates, increasing the maximum air outlet speed of the air outlet assembly and preventing some airflow from being delayed due to rotation, thus reducing the air volume; the second housing configuration makes the installation of the condenser heat exchanger more stable; the tilted configuration of the condenser heat exchanger increases the contact area between the airflow entering at the condenser air inlet and the condenser heat exchanger, improving heat exchange efficiency; the third extension section increases the volume of the air inlet buffer space, making the air intake at the condenser air inlet smoother; the condenser assembly and the air outlet assembly work together to ensure uniform air volume while making the air outlet temperature more accurate.
[0006] In one embodiment of the present invention, the protrusion includes: a first accelerating surface, which is arc-shaped; a second accelerating surface, which is arc-shaped, and is connected to the first accelerating surface and extends in the direction of the connecting portion; wherein the first accelerating surface and the second accelerating surface are both located at the upper end of the housing, the first fan sends air to the connecting portion, and the air passes through the first accelerating surface; and / or, the second accelerating surface enters the air outlet channel.
[0007] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The setting of the first acceleration surface and the second acceleration surface allows the rotating airflow after passing through the fan to maintain a uniform acceleration speed as it moves to the first air outlet, avoiding resistance to the rotating airflow inside the first housing. The setting of the first acceleration surface matching the outer contour of the first fan makes the rotating airflow driven by the first fan more compatible with the first acceleration surface. The setting of the second acceleration surface gradually moving away from the first fan towards the side closer to the connection increases the air inlet angle for the rotating airflow to enter the air outlet channel from inside the first housing, avoiding air outlet delay.
[0008] In one embodiment of the present invention, the second housing includes: an upper housing, a second air inlet disposed on the upper housing, a third extension section disposed on the side of the upper housing away from the second air outlet, the third extension section being fixedly connected to the condensing heat exchanger and forming an air inlet buffer space; a middle housing, the middle housing being connected to the upper housing, the condensing heat exchanger being located between the upper housing and the middle housing, and a static pressure chamber being formed between the middle housing and the condensing heat exchanger; and a lower housing, a second air outlet disposed on the lower housing, a second fan disposed inside the lower housing, an air outlet section being formed between the second fan and the second air outlet, the second fan being connected to the static pressure chamber and capable of driving the gas in the static pressure chamber to the air outlet section.
[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the bending of the third extension section increases the distance between the condenser heat exchanger and the top of the upper shell, allowing more gas to be contained in this area to form a uniform air inlet surface; the cooperation between the lower shell and the middle shell allows the upper end of the air outlet section to have a variable design; and the lower end of the second air outlet is horizontally tangent to the air outlet direction to ensure that the air outlet velocity is not affected.
[0010] In one embodiment of the present invention, the middle shell includes: a bottom plate; a first side plate, which contacts the condensing heat exchanger and is disposed on the side of the bottom plate near the second air inlet; and a second side plate, which contacts the condensing heat exchanger and is disposed on the side of the bottom plate away from the second air inlet; wherein, a static pressure cavity is formed between the first side plate, the second side plate, the bottom plate, and the condensing heat exchanger, and a third inclined surface is provided on the side of the bottom plate near the second air outlet, the first side plate is fixedly connected to the third inclined surface, and a heat dissipation buffer space is formed between the third inclined surface, the condensing heat exchanger, and the first side plate.
[0011] Compared with existing technologies, the technical effects achieved by this solution are as follows: The arrangement of the first and second side plates allows the condenser heat exchanger to be tilted and fixed between the middle and upper shells. The first side plate also increases the distance between the bottom plate and the condenser heat exchanger, increases the area of the static pressure chamber, and allows the airflow passing through the condenser heat exchanger to smoothly enter the corner of the static pressure chamber, improving the heat exchange efficiency of the condenser heat exchanger. The arrangement of the third inclined surface further increases the distance between the condenser heat exchanger and the bottom plate, allowing the airflow at the air inlet buffer space expanded by the bend section to smoothly enter the heat dissipation buffer space after passing through the condenser heat exchanger, improving the heat exchange efficiency of the condenser heat exchanger, and making the airflow at the second air outlet smoother.
[0012] In one embodiment of the present invention, the portable air conditioner further includes: a housing, the lower surface of which is the bottom of the housing, an air outlet assembly and a condenser assembly disposed inside the housing, and a water outlet hole provided on the housing; a base, which is connected to the bottom of the housing and located outside the housing; and a water collection tank, which is connected to the bottom of the housing, with at least a portion of the water collection tank passing through the water outlet hole; wherein the air outlet assembly is located above the water collection tank, the condensate generated by the air outlet assembly can enter the water collection tank, the condensate can flow in the water collection tank, and the water outlet hole is located on the side of the housing near the direction of condensate flow.
[0013] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by changing the position of the water outlet on the outer casing, the flow distance of condensate in the water collection tank is shortened, allowing the condensate in the water collection tank to be quickly discharged from the inside of the outer casing, ensuring that the evaporator can work normally, and also reducing the volume of the water collection tank, making the overall installation of the portable air conditioner more convenient.
[0014] In one embodiment of the present invention, the water collection tank includes: a water receiving tray located between the air outlet assembly and the bottom of the shell; a water storage cavity connected to the water receiving tray, the height of the water storage cavity being lower than the height of the water receiving tray; and a water outlet pipe connected to the water storage cavity, the water outlet pipe passing through a water outlet hole; wherein, the surface of the water receiving tray is provided with a water receiving surface recessed towards the bottom of the shell, the water receiving surface is obliquely arranged, and the end of the water receiving surface near the water outlet pipe is closer to the bottom of the shell than the side of the water receiving surface away from the water outlet pipe.
[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: the drip tray allows condensate dripping from the evaporator to smoothly enter the water collection tank; the water storage chamber continuously collects condensate dripping from the drip tray; the outlet pipe allows water in the water storage chamber to drain; the baffle allows water entering the water storage chamber to be diverted, and can smoothly guide the flow when condensate is generated quickly, improving the stability of the drip surface in terms of drainage. The first and second inclined surfaces prevent excessive condensate residue in the water storage chamber, increasing the maximum condensate flow rate that the water collection tank can handle; and the height of the outlet pipe allows condensate in the second water channel to drain smoothly. The design of the first and second water inlets allows condensate to drain smoothly from the water storage chamber, ensuring the normal operation of the portable air conditioner. The curved surfaces of the first and second water inlets allow gravity to drive the condensate flow without the need for external assistance, simplifying the structure of the water storage chamber. The groove design enables the conversion of the condensate flow direction, preventing the condensate from moving obliquely while minimizing the flow distance and achieving rapid drainage.
[0016] In one embodiment of the present invention, the outer casing is provided with a third air inlet and a third air outlet. The third air inlet cooperates with the second air inlet, and the third air outlet cooperates with the second air outlet. A filter screen is provided between the third air inlet and the second air inlet. There is a gap between the inner surface of the third air outlet and the outer surface of the second air outlet. The gap is set along the outer contour of the second air outlet and forms an annular ventilation outlet.
[0017] Compared with existing technologies, the technical effects achieved by this solution are as follows: The design of the third and second air inlets ensures that when the condenser assembly draws outside air into the portable air conditioner, it must pass through the third and second air inlets sequentially. The filter screen filters the outside air as it passes through the third air inlet, reducing contaminants entering the second air inlet, ensuring the normal operation of the condenser assembly, and improving the heat exchange effect of the portable air conditioner during operation. The design of multiple gaps forming an annular ventilation outlet allows heat inside the casing to be discharged more smoothly, further improving the operational stability of the portable air conditioner.
[0018] In one embodiment of the present invention, the filter screen includes: a filter panel with a notch; a first snap-fit portion located on the side of the filter panel near the condenser assembly, the first snap-fit portion being detachably connected to a third air outlet; and / or, the first snap-fit portion being detachably connected to a third air inlet; a filter frame fixedly connected to a housing, the filter frame containing a mesh sheet; the first snap-fit portion includes: a first snap-fit member located in the notch, at least a portion of the first snap-fit member extending toward the condenser assembly, and having a bend at the extended end, the bend enabling the first snap-fit member to engage with the third air outlet; a second snap-fit member extending toward the condenser assembly, the extended end having a buckle, the buckle engaging with the third air outlet; the first snap-fit member and the second snap-fit member are located on opposite sides of the filter panel.
[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: the filter panel effectively filters pollutants from the external airflow; the detachable design of the first snap-fit part and the third air inlet makes daily maintenance of the filter screen more convenient; the separate snap-fit design of the first and second snap-fit parts makes the connection between the filter screen and the third air outlet or the third air inlet more stable; and the notch design allows the first snap-fit part to be easily disconnected, making the disassembly of the filter panel more convenient.
[0020] In one embodiment of the present invention, the portable air conditioner further includes: a mounting part disposed on a base, the mounting part including a mounting groove extending downward along the upper surface of the base, the mounting groove being hollow, and the upper edge of the mounting groove extending toward the center of the mounting groove to form a mounting position; a second snap-fit part located on the side of the outer shell near the base and protruding toward the base, at least a portion of the second snap-fit part entering the mounting groove and being able to slide into the mounting position.
[0021] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the cooperation between the mounting slot and the second snap-fit part makes it more convenient to fix the shell and the base directly. When the shell and the base are connected, the second snap-fit part does not need to be aligned after entering the mounting slot. Assembly can be achieved simply by moving it, which improves the convenience of assembly. Attached Figure Description

Detailed Implementation
[0056] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0057] [First Embodiment]
[0058] See Figures 1 to 11 as well as Figures 30 to 32In one specific embodiment, the present invention provides a portable air conditioner 100, which includes an air outlet assembly and a condenser assembly. The air outlet assembly and the condenser assembly are connected in cooperation. The air outlet assembly includes: a front panel 170, on which a first air inlet 111 and a first air outlet 112 are provided, the first air inlet 111 being connected to a first fan 160; a volute 120, which is connected in cooperation with the front panel 170, and the first fan 160 is provided inside the volute 120. The volute 120 includes: a first housing 121, in which the first fan 160 is disposed, the first housing 121 having a protrusion 150, the inner wall of the protrusion 150 forming an air duct acceleration surface; and a connecting part 123, which is connected to the first air outlet 112, and the first fan 160 is connected to the connecting part. An air outlet channel is formed between 123. After the first fan 160 drives the air to rotate, the air is accelerated through the protrusion 150 and enters the air outlet channel. The evaporator 140 is fixedly connected to the volute 120 and is located between the volute 120 and the front panel 170. The condenser assembly includes: a second housing 201, on which a second air inlet 211 and a second air outlet 231 are provided, and the second air outlet 231 is connected to the second air inlet 211; a condensing heat exchanger 240, which is connected to the evaporator 140. The condensing heat exchanger 240 is inclined and located between the second air outlet 231 and the second air inlet 211. A receiving cavity is formed between the condensing heat exchanger 240 and the second air inlet 211. An air inlet buffer space 250 is provided on the side of the receiving cavity away from the second air inlet 211.
[0059] The first air inlet 111 is located at the lower end of the front panel 170, and the first air outlet 112 is located at the upper end of the front panel 170. The upper end of the volute 120 is connected to the upper end of the front panel 170, and an evaporator 140 is provided between the lower end of the front panel 170 and the lower end of the volute 120. The lower end of the first housing 121 has a through hole, the position of which matches the position of the evaporator 140. A first fan 160 is fixedly connected inside the through hole. The first housing 121 has protrusions 150 on the left and right sides opposite to the air inlet direction. A sealing cover 122 is provided on the side away from the first air outlet 112. The sealing cover 122 is fixed to the first housing 121 by a snap fastener. A receiving space is formed between the sealing cover 122 and the first housing 121. The connecting part 123 is located at the upper end of the first housing 121. A protrusion is provided on the rear side of the front panel 170. Both the protrusion and the connecting part 123 are hollow frame 123d. When the protrusion and the connecting part 123 are connected, the receiving space between the sealing cover 122 and the first housing 121 is connected to the first air outlet 112, forming an air outlet channel.
[0060] The button on the front panel 170 of the air outlet assembly can control the operation and stop of the air outlet assembly. When the air outlet assembly is cooling, the first fan 160 draws in hot air from the outside by rotating. After heat exchange in the evaporator 140, cold air is formed. The cold air generated at this time is located in the containment space. When the cold air passes through the first fan 160, the first fan 160 will make the cold air rotate and accelerate, and impact the inner wall of the first housing 121. Under the action of the protrusion 150, the rotating cold air flow is more closely attached to the inner wall of the first housing 121, making the cold air flow faster and able to be discharged from the first air outlet 112 more quickly.
[0061] In related technologies, an obstruction is provided between the connecting part 123 of the volute 120 and the first fan 160. Some of the accelerated airflow cannot be discharged smoothly from the first air outlet 112 and remains inside the volute 120, resulting in insufficient airflow.
[0062] The condensing heat exchanger 240 is fixed to the second housing 201. The pipes of the condensing heat exchanger 240 are located outside the second housing 201. The upper housing 210 is provided with a second air outlet 231. The end of the upper housing 210 away from the second air outlet 231 is provided with a third extension section 213. An air inlet buffer space 250 is formed between the inner surface of the upper housing 210 and the upper surface of the condensing heat exchanger 240. The middle section of the upper housing 210 is inclined to the side away from the condensing heat exchanger 240, which increases the distance between the inner surface of the upper housing 210 and the condensing heat exchanger 240 and expands the volume of gas that can be contained in the air inlet buffer space 250. Under normal circumstances, the volume of the air inlet buffer space 250 is the same as the volume of the condensing heat exchanger 240, ensuring that the condensing heat exchanger 240 can fully exchange heat under the maximum air inlet area.
[0063] When the condenser assembly is running, the outside airflow can enter the buffer air inlet space from the second air outlet 231, and move towards the second air outlet 231 after passing through the condenser heat exchanger 240. By tilting the condenser heat exchanger 240, which is relatively parallel or nearly parallel to the air inlet direction, the contact area between the airflow entering from the condenser air inlet and the condenser heat exchanger 240 is increased, so that the entire air inlet surface of the condenser heat exchanger 240 will have a more uniform airflow, thereby making the airflow on the air outlet side of the condenser heat exchanger 240 more uniform.
[0064] In related technologies, no third extension section 213 is provided at the position of the upper shell 210 of the condenser assembly. The side of the condenser heat exchanger 240 near the upper surface of the upper shell 210 is close to the inner surface of the upper shell 210. The cross-sectional shape of the air inlet buffer space 250 is close to a triangle, which causes some airflow to be unable to enter the condenser air inlet smoothly. At the same time, the volume of the air inlet buffer space 250 is insufficient, and the air intake at the condenser air inlet is not smooth enough.
[0065] The front panel 170 and the volute 120 enable the air outlet assembly to perform both air intake and exhaust functions. The first fan 160 allows outside air to be drawn into the first housing 121. The protrusion 150 further accelerates the airflow after the first fan 160 rotates, increasing the maximum airflow speed of the air outlet assembly and preventing some airflow from being delayed due to rotation, thus reducing the airflow volume. The second housing 201 makes the installation of the condenser heat exchanger 240 more stable. The inclined design of the condenser heat exchanger 240 increases the contact area between the airflow entering at the condenser air inlet and the condenser heat exchanger 240, improving heat exchange efficiency. The third extension section 213 increases the volume of the air inlet buffer space 250, making the airflow at the condenser air inlet smoother. The condenser assembly and the air outlet assembly work together to ensure uniform airflow while making the airflow temperature more accurate.
[0066] [Second Embodiment]
[0067] See Figures 2 to 4 as well as Figure 30 and Figure 32 In one specific embodiment, the protrusion 150 includes: a first acceleration surface 151, which is arc-shaped; and a second acceleration surface 152, which is arc-shaped, and is connected to the first acceleration surface 151 and extends toward the connecting portion 123; wherein the first acceleration surface 151 and the second acceleration surface 152 are both located at the upper end of the housing 121, the first fan 160 sends air to the connecting portion 123, and the air passes through the first acceleration surface 151; and / or, the second acceleration surface 152 enters the air outlet channel.
[0068] Normally, the protrusion 150 is located at the upper left end of the first housing. The first acceleration surface 151 and the second acceleration surface 152 are arc-shaped. The fan 160 is cylindrical. The side wall of the fan 160 is provided with a grille. The fan blades inside the fan 160 rotate to make the airflow flow in the direction of rotation and increase the airflow speed. After acceleration, the airflow first passes through the side wall of the first housing 121 and turns, and moves to the upper left of the first housing 121. The first acceleration surface 151 can guide the airflow located on the right side of the first housing 121, so that the airflow movement direction is towards the connecting part 123. The arc shape is more in line with the direction of airflow, reducing the contact between the airflow and the inner wall of the first housing 121, which would cause the airflow speed to decrease. The airflow located below the first acceleration surface 151 can be accelerated by the second acceleration surface 152. The airflow is accelerated under the guidance of the second acceleration surface 152. The rotating airflow accelerates and cuts into the frame 123d of the connecting part 123, and finally the concentrated airflow is introduced into the air outlet 112.
[0069] Furthermore, the first acceleration surface 151 is arc-shaped. Under the action of the inner wall of the first housing 121, some airflow can flow along the inner wall to the top of the fan 160 when the fan 160 rotates. At this time, the first acceleration surface 151 can smoothly accelerate this airflow. During the movement along the first acceleration surface 151, in order to allow the airflow to better enter the connecting part 123, the surface area of the first acceleration surface 151 that guides the airflow decreases as the first acceleration surface 151 approaches the connecting part, so as to avoid affecting the normal air outlet at the connecting part 123 due to the first acceleration surface 151 occupying too much space. Another portion of the airflow moves directly above the fan when the fan 160 rotates. If the airflow speed is too fast, it cannot directly enter the connecting part 123. At this time, under the action of the second acceleration surface 152, this portion of the airflow is smoothly guided to the connecting part 123 and enters the air outlet channel. The first acceleration surface 151 and the second acceleration surface 152 work together to avoid the delayed discharge of airflow inside the first housing 121. Compared with the 90° right angle between the rotating airflow and the air outlet channel in the related technology, the airflow has a larger angle to enter the air outlet channel, which can increase the rotation delay discharge airflow by 15%.
[0070] Furthermore, the connecting portion 123 also includes: a first extension 123a, which is connected to the first housing 121 and extends towards the side near the first air outlet 112; a second extension 123b, which is inclined and connected to the top of the first housing 121; wherein both the first extension 123a and the second extension 123b are connected to the front panel 170. The air outlet assembly also includes: an evaporator 140, which is fixedly connected to the volute 120 and located between the volute 120 and the front panel 170; a water collection tank 130, which is connected to the evaporator 140. The first extension 123a is longer than the second extension 123b. The first extension 123a is horizontally positioned, and the second extension 123b is horizontally positioned. The extension section 123b is inclined from above the first housing 121 toward the first air outlet 112. The protrusion on the rear side of the front panel 170 is adapted to the inclination of the second extension section 123b. After the protrusion and the frame 123d are engaged, an upwardly inclined air outlet channel is formed, which can deliver air to a farther position, thereby achieving a larger air volume flow from the first air inlet 111 to the first air outlet 112, so that the air conditioner can obtain a larger cooling capacity. The evaporator 140 is engaged with the first extension section 123a, located below the first extension section 123a, and attached to the front side of the first housing 121. The air passing through the evaporator 140 can enter the first housing 121 through the fan. The water collection tank 130 is located below the evaporator 140 and is used to collect the condensate generated by the operation of the evaporator 140.
[0071] The inclined design of the second extension section 123b allows the air outlet assembly to deliver air to a farther location and also allows the air outlet channel to be adapted to the protrusion 150, further increasing the air volume. The design of the first extension section 123a allows the evaporator 140 to be fixed to the air outlet assembly. The design of the water collection tank 130 ensures the normal operation of the evaporator 140 and improves the stability of the air outlet assembly.
[0072] Furthermore, the connecting part 123 also includes a fixing frame 123c, which is located at the lower end of the first extension 123a. The left and right sides of the evaporator 140 relative to the air inlet direction are fixed by the fixing frame 123c. The lower end of the evaporator 140 cooperates with the water collection tank 130. The setting of the fixing frame 123c makes the evaporator more firmly fixed and also makes the evaporator 140 fit more closely to the volute 120, so that the condensed air can quickly enter the first housing 121.
[0073] The arrangement of the first acceleration surface 151 and the second acceleration surface 152 allows the rotating airflow after passing through the fan to maintain a constant acceleration speed as it moves to the first air outlet 112, avoiding resistance to the rotating airflow inside the first housing 121. The arrangement of the first acceleration surface 151 to match the outer contour of the first fan 160 makes the rotating airflow driven by the first fan 160 more compatible with the first acceleration surface 151. The arrangement of the second acceleration surface 152 to gradually move away from the first fan 160 towards the side closer to the connecting part 123 increases the air inlet angle for the rotating airflow to enter the air outlet channel from inside the first housing 121, avoiding air outlet delay.
[0074] [Third Embodiment]
[0075] See Figures 5 to 11 In one specific embodiment, the second housing 201 includes: an upper housing 210, a second air inlet 211 disposed on the upper housing 210, a third extension section 213 disposed on the side of the upper housing 210 away from the second air outlet 231, the third extension section 213 being fixedly connected to the condensing heat exchanger 240 and forming an air inlet buffer space 250; a middle housing 220, the middle housing 220 being connected to the upper housing 210, the condensing heat exchanger 240 being located between the upper housing 210 and the middle housing 220, and a static pressure chamber 280 being formed between the middle housing 220 and the condensing heat exchanger 240; and a lower housing 230, a second air outlet 231 disposed on the lower housing 230, a second fan 270 disposed inside the lower housing 230, an air outlet section being formed between the second fan 270 and the second air outlet 231, the second fan 270 being connected to the static pressure chamber 280 and capable of driving the gas in the static pressure chamber 280 to the air outlet section.
[0076] The third extension section 213 is inclined, and the inclination angle of the third extension section 213 is adapted to the inclination angle of the condensing heat exchanger 240.
[0077] Furthermore, the third extension section 213 includes a first section 213a and a second section 213b. The first section 213a is connected to the second section 213b. An air inlet space 251 is formed between the first section 213a and the condenser heat exchanger 240, and an air inlet buffer space 250 is formed between the second section 213b and the upper shell 210.
[0078] The third extension section 213 is located on the side of the upper shell 210 away from the second air inlet 211. The outer surface of the third extension section 213 is flush with the side of the condenser heat exchanger 240, and the lower surface of the third extension section 213 is in contact with the upper surface of the condenser heat exchanger 240, that is, the first section 213a is in contact with the upper surface of the condenser heat exchanger 240, thereby forming an air inlet buffer space 250. The second section 213b increases the distance between the upper surface of the condenser heat exchanger 240 and the upper surface of the shell 201, increasing the air inlet buffer space 250, and also allowing the airflow located at the bend of the upper shell 210 to enter the condenser air inlet in a direction perpendicular to the condenser heat exchanger 240.
[0079] The first section 213a is designed to form an air intake space 251 within the accommodating cavity. The second section 213b further increases the volume of the accommodating cavity and forms an air intake buffer space 250 at the upper end of the air intake space 251. The air intake buffer space 250 ensures that when vortices are formed at the corners of the accommodating cavity, the contact area between the condenser heat exchanger 240 and the incoming airflow will not be affected, thus further improving the heat exchange efficiency.
[0080] It should be noted that the connection between the first segment 213a and the second end 213b can be horizontal or bent.
[0081] In related technologies, no third extension section 213 is provided at the position of the upper shell 210 of the condenser assembly 110. The side of the condenser heat exchanger 240 near the upper surface of the upper shell 210 is close to the inner surface of the upper shell 210. The cross-sectional shape of the air inlet buffer space 250 is close to a triangle, which causes some airflow to be unable to enter the condenser air inlet smoothly. At the same time, the volume of the air inlet buffer space 250 is insufficient, and the air intake at the condenser air inlet is not smooth enough.
[0082] A second fan 270 is provided in the middle of the lower shell 230. The upper surface of the lower shell 230 is attached to the lower surface of the middle shell 220 to form an air outlet section and a second air outlet 231, and they are fixedly connected by screws. The position of the second fan 270 is matched with the connection hole 227 on the bottom plate 225. The second fan 270 brings the airflow in the static pressure chamber 280 into the air outlet section by rotating.
[0083] The inclined setting of the third extension section 213 increases the distance between the condenser heat exchanger 240 and the top of the upper shell 210, allowing more gas to be contained therein, so as to form a uniform air inlet surface. The cooperation between the lower shell 230 and the middle shell 220 allows the upper end of the air outlet section to have a variable design. The lower end of the second air outlet 231 is horizontally tangent to the air outlet direction, ensuring that the air outlet speed is not affected.
[0084] [Fourth Embodiment]
[0085] In one specific embodiment, the middle shell 220 includes: a bottom plate 225; a first side plate 221, which contacts the condenser heat exchanger 240 and is disposed on the side of the bottom plate 225 near the second air inlet 211; and a second side plate 222, which contacts the condenser heat exchanger 240 and is disposed on the side of the bottom plate 225 away from the second air inlet 211; wherein, a static pressure cavity 280 is formed between the first side plate 221, the second side plate 222, the bottom plate 225 and the condenser heat exchanger 240, a third inclined surface 226 is provided on the side of the bottom plate 225 near the second air outlet 231, the first side plate 221 is fixedly connected to the third inclined surface 226, and a heat dissipation buffer space 260 is formed between the third inclined surface 226, the condenser heat exchanger 240 and the first side plate 221.
[0086] The base plate 225 is provided with side plates on all four sides. The left and right sides of the middle shell 220 are the air inlet directions. The first side plate 221 and the second side plate 222 are located on the left and right sides of the base plate 225, respectively. The height of the side plates on the front and rear sides of the base plate 225 is higher than the height of the first side plate 221 and the second side plate 222. The right side of the middle shell 220 is provided with a fixing member, which is usually a connecting rod. After the side plates on the front and rear sides contact the lower surface of the upper shell 210, the connecting rod is connected to the upper shell 210 to realize the connection between the middle shell 220 and the upper shell 210, and fix the condensing heat exchanger 240 between the middle shell 220 and the upper shell 210. The base plate 225 is provided with a third connecting hole 227. The third connecting hole 227 is a through hole. The airflow through the condensing heat exchanger 240 moves in the air outlet direction through the third connecting hole 227. The height of the first side plate 221 on the left side of the condensing heat exchanger 240 is lower than the height of the second side plate 222. The lower surface of the left side of the condensing heat exchanger 240 is in contact with the upper surface of the first side plate 221, and the lower surface of the right side of the condensing heat exchanger 240 is in contact with the upper surface of the second side plate 222. The height difference between the first side plate 221 and the second side plate 222 allows the condensing heat exchanger 240 to be tilted. The close connection method improves the airtightness of the static pressure chamber 280.
[0087] The lower end of the first baffle 223 is fixedly connected to the third inclined surface 226. The side of the first baffle 223 is fixedly connected to the first side plate 221. The first baffle 223 is at least partially higher than the first side plate 221. The side of the second baffle 224 is fixedly connected to the second side plate 222. The second baffle 224 is at least partially higher than the second side plate 222. The left and right sides of the condensing heat exchanger 240 are in contact with the first baffle 223 and the second baffle 224 respectively. The inner sides of the first side plate 221 and the second side plate 222 are provided with reinforcing ribs.
[0088] After the airflow passes through the condenser and enters the static pressure chamber 280, the airflow moves towards the second air outlet 231 through the third connecting hole 227 on the base plate 225. The setting of the first side plate 221 increases the distance between the bottom of the condensing heat exchanger 240 and the base 180, increasing the area inside the static pressure chamber 280. At this time, the cross-sectional area of the static pressure chamber 280 is approximately trapezoidal. In related technologies, the distance between the condenser and the base 180 of the middle shell 220 is small, that is, the first baffle 223 is not set, which results in the distance between the right side of the condensing heat exchanger 240 and the base 180 being too small, making the cross-section of the static pressure chamber 280 approximately triangular. In the corner, due to the small local space, sufficient heat exchange cannot be achieved.
[0089] Furthermore, a third inclined surface 226 is provided on the side of the base plate 225 near the second air outlet 231, and the first side plate 221 is fixedly connected to the third inclined surface 226; wherein, a heat dissipation buffer space 260 is formed between the third inclined surface 226, the condensing heat exchanger 240 and the first side plate 221.
[0090] The right side of the base plate 225 is a flat surface, and the left end is a third inclined surface 226. The second side plate 222 is set on the flat surface, and the first side plate 221 is set on the third inclined surface 226. The third inclined surface 226 is inclined towards the direction of the second air outlet 231, which is more compatible with the inclined condensing heat exchanger 240.
[0091] It should be noted that the heat dissipation buffer space 260 refers to the space formed on the right side of the middle shell 220 due to the setting of the first side plate 221, and the cross-sectional shape of the heat dissipation buffer space 260 is roughly a parallelogram.
[0092] It should be noted that the tilt angle of the condenser heat exchanger 240 is between ° and °. Preferably, the length of the first side plate 221 is one-quarter of the thickness of the condenser, and the length of the second side plate 222 is equal to the thickness of the condenser.
[0093] The third inclined plane 226 further increases the distance between the condenser heat exchanger 240 and the base plate 225, allowing the airflow at the air inlet buffer space 250, which is expanded by setting the bend section, to smoothly enter the heat dissipation buffer space 260 after passing through the condenser heat exchanger 240, thereby improving the heat exchange efficiency of the condenser heat exchanger 240 and making the air outlet at the second air outlet 231 more smooth.
[0094] The arrangement of the first side plate 221 and the second side plate 222 allows the condenser heat exchanger 240 to be tilted and fixed between the middle shell 220 and the upper shell 210. The first side plate 221 also increases the distance between the bottom plate 225 and the condenser heat exchanger 240, increases the area of the static pressure chamber 280, and allows the airflow passing through the condenser heat exchanger 240 to smoothly enter the corner of the static pressure chamber 280, improving the heat exchange efficiency of the condenser heat exchanger 240. The arrangement of the third inclined surface 226 further increases the distance between the condenser heat exchanger 240 and the bottom plate 225, allowing the airflow at the air inlet buffer space 250, which is expanded by setting the bend section, to smoothly enter the heat dissipation buffer space 260 after passing through the condenser heat exchanger 240, improving the heat exchange efficiency of the condenser heat exchanger 240, and making the airflow at the second air outlet 231 smoother.
[0095] [Fifth Embodiment]
[0096] See Figures 12 to 17 In one specific embodiment, the portable air conditioner 100 further includes: a housing 110, the lower surface of which is a bottom 117; an air outlet assembly and a condenser assembly disposed inside the housing 110; and a water outlet 114 provided on the housing 110; a base 180, which is connected to the bottom 117 and located outside the housing 110; and a water collection tank 130, which is connected to the bottom 117, with at least a portion of the water collection tank passing through the water outlet 114; wherein the air outlet assembly is located above the water collection tank 130, and the condensate generated by the air outlet assembly can enter the water collection tank 130, and the condensate can flow in the water collection tank 130; and the water outlet 114 is located on the side of the housing 110 near the direction of condensate flow.
[0097] The base 180 and the outer casing 110 cooperate to form an enclosing space. The water collection tank 130 is fixedly connected to the base 180 and located within the enclosing space. The air outlet assembly includes a volute 120 and an evaporator 140. A fan is installed inside the volute 120. The volute 120 includes a housing and a sealing cover 122. The fan is located between the housing and the sealing cover 122. A protrusion 150 is provided at the front end of the housing. The protrusion 150 rests on the evaporator 140 and is fixedly connected to the evaporator 140. After the evaporator 140 is fixed, it is located above the water collection tank 130. The outer casing 110 is located near... A water outlet 114 is provided on one side of the water collection tank 130. The water outlet 114 is connected to the water collection tank 130. The water outlet 114 is located on the side of the outer shell 110 near the water outlet position of the water collection tank 130. For example, after the condensate produced by the evaporator 140 enters the water collection tank 130, the condensate moves to the right. At this time, the water outlet 114 is located on the right side of the outer shell 110. It can be understood that if the condensate produced by the evaporator 140 enters the water collection tank 130, the condensate moves to the left. At this time, the water outlet 114 is located on the left side of the outer shell 110.
[0098] When the portable air conditioner 100 is working, the fan inside the casing rotates and brings airflow into the casing. Heat exchange is completed in the evaporator 140. During the heat exchange process, condensate is generated and drips down into the water collection tank 130. When the condensate reaches a certain volume, it is discharged through the water outlet 114. Because the distance between the water outlet 114 and the water collection tank 130 is relatively short, and the condensate moves towards the water outlet 114 after dripping, the portable air conditioner 100 can quickly discharge the condensate, avoiding long-distance drainage through the water collection tank 130.
[0099] In related technologies, after the condensate produced by the evaporator 140 enters the water collection tank 130, the water collection tank 130 needs to travel an excessively long distance to guide the condensate out. This not only makes the structure of the water collection tank 130 complex and occupies the installation space on the base 180, but also makes it impossible to drain the condensate in a timely manner.
[0100] By changing the position of the water outlet 114 on the outer casing 110, the flow distance of condensate in the water collection tank 130 is shortened, allowing the condensate in the water collection tank 130 to be quickly discharged from the inside of the outer casing 110. This ensures that the evaporator 140 can work normally and also reduces the volume of the water collection tank 130, making the overall installation of the portable air conditioner 100 more convenient.
[0101] [Sixth Embodiment]
[0102] In one specific embodiment, the water collection tank 130 includes: a water receiving tray 133, which is located between the air outlet assembly and the bottom of the shell 117; a water storage cavity 134, which is connected to the water receiving tray 133, and the height of the water storage cavity 134 is lower than the height of the water receiving tray 133; and a water outlet pipe 131, which is connected to the water storage cavity 134 and passes through a water outlet hole 114; wherein, the surface of the water receiving tray 133 is provided with a water receiving surface 132 that is recessed towards the bottom of the shell 117, the water receiving surface 132 is obliquely arranged, and the end of the water receiving surface 132 near the water outlet pipe 131 is closer to the bottom of the shell 117 than the side of the water receiving surface 132 away from the water outlet pipe 131.
[0103] The housing is provided with a receiving groove 113, and a water outlet 114 is located in the receiving groove 113. The water outlet pipe 131 passes through the water outlet 114 and enters the receiving groove 113. A water collection tray 133 is provided on the side of the water collection tank 130 away from the water outlet. The water collection tray 133 is arranged horizontally on the base 180 in the left-right direction, usually perpendicular to the air outlet direction. The connection between the water storage cavity 134 and the water collection tray 133 is L-shaped. The water storage cavity 134 is located at the lower end of the water collection tray 133, which facilitates the water in the water collection tray 133 to enter the water storage cavity 134. The other end of the water storage cavity 134 extends towards the water outlet 114. Under normal circumstances, the placement direction of the water storage cavity 134 is perpendicular to the placement direction of the water collection tray 133. The water outlet pipe 131 is connected to the water storage cavity 134 and can pass through the water outlet 114.
[0104] When the condensate from the evaporator 140 enters the water receiving pan 133, the condensate flows along the water receiving pan 133 into the water storage chamber 134. As the amount of condensate in the water storage chamber 134 increases, the condensate can move towards the outlet pipe 131 and enter the outlet pipe 131. Finally, the condensate is discharged to the outside of the outer casing 110 by the outlet pipe 131.
[0105] Furthermore, the upper surface of the water receiving tray 133 is recessed downward to form a water receiving surface 132. The water receiving surface 132 is inclined and gradually decreases from right to left. Under the action of gravity, the condensate dripping on the water receiving surface 132 will flow into the water storage chamber 134. The position of the water receiving surface 132 is adapted to the installation position of the evaporator 140 to ensure that the condensate can drip smoothly into the water receiving surface 132.
[0106] Furthermore, the partition 135 is located at the center of the water receiving surface 132 and divides the water receiving surface 132 into two water receiving surfaces. The lower surface of the partition 135 is in contact with the water receiving surface 132, and the upper surface of the partition 135 is at the same height as the water receiving tray 133.
[0107] Furthermore, the water storage chamber 134 includes: a first water inlet channel 134a, one end of which engages with the water receiving surface 132, and the other end extends toward the water outlet pipe 131; a second water inlet channel 134b, one end of which is connected to the first water inlet channel 134a, and the other end is connected to the water outlet pipe 131, and a groove 138 is provided at the connection between the second water inlet channel 134b and the first water inlet channel 134a; wherein, the condensate in the water receiving surface 132 enters the water outlet pipe 131 after passing through the first water inlet channel 134a and the second water inlet channel 134b, the first water inlet channel 134a and the second water inlet channel 134b are arc-shaped and inclined, and the distance between the surface of the first water inlet channel 134a and the base 180 decreases as it approaches the groove 138.
[0108] The first water inlet channel 134a is horizontally arranged in the front-to-back direction, with its rear end flush with the front side of the water receiving surface 132, ensuring that all water dripping from the water receiving surface 132 can enter the first water inlet channel 134a. The second water inlet channel 134b is located at the position where the first water inlet channel 134a is flush with the water outlet 114 in the left-to-right direction, and its direction is consistent with that of the water receiving surface 132. The condensate in the first water inlet channel 134a will move towards the groove 138. When there is condensate in the water chamber 8, the second water channel 134b will move the condensate towards the outlet pipe 131, carrying the condensate out of the water storage chamber 134. The surfaces of the first water channel 134a and the second water channel 134b are both arc surfaces. The height of the first water channel 134a is lowest near the groove 138, and the height increases with the increase of the distance between it and the groove 138. The height of the second water channel 134b is lowest at the end near the outlet pipe 131, and the height increases with the increase of the distance between it and the outlet pipe 131.
[0109] When the condensate flow rate is small, the front section of the first water inlet channel 134a and the left section of the second water inlet channel 134b can complete the discharge of condensate. When the condensate flow rate is large, condensate may flow into the rear section of the first water inlet channel 134a and the right section of the second water inlet channel 134b. However, on the inclined arc surface, the condensate will also move towards the groove 138 and eventually flow to the outlet pipe 131.
[0110] It should be noted that the first water inlet channel 134a and the second water inlet channel 134b are set vertically to avoid the condensate water from having to pass through bends during its flow, thus ensuring smooth flow of the condensate water while also reducing the flow distance of the condensate water.
[0111] It should be noted that the front and rear sections of the first water channel 134a are divided by the position of the groove 138, and the left and right sections of the second water channel 134b are also divided by the position of the groove 138.
[0112] Furthermore, a first inclined surface 136 is provided between the side wall of the water storage cavity 134 and the first water inlet channel 134a. A second inclined surface 137 is provided on the side of the first inclined surface 136 near the first water inlet channel 134a. The second inclined surface 137 is connected to the first water inlet channel 134a. At least a portion of the water outlet pipe 131 is located inside the outer shell 110. The lower surface of the water outlet pipe 131 is flush with the surface of the second water inlet channel 134b.
[0113] The slope of the first inclined surface 136 is less than that of the second inclined surface 137. When the flow rate of condensate on the water receiving surface 132 is large, because there is a height difference between the water storage cavity 134 and the water receiving surface 132, the dripping condensate will splash up, and some water droplets will drip to the outside of the first water inlet channel 134a. At this time, the first inclined surface 136 and the second inclined surface 137 cooperate to allow the external water droplets to enter the first water inlet channel 134a, so as to avoid too much condensate remaining in the water storage cavity 134. The lower surface of the outlet pipe 131 is flush with the lowest height of the second water inlet channel 134b, so as to ensure that the condensate can flow into the outlet pipe 131 when it flows on the surface of the second water inlet channel 134b.
[0114] The drip tray 133 allows condensate dripping from the evaporator 140 to smoothly enter the water collection tank 130. The water storage chamber 134 continuously collects condensate dripping along the drip tray 133. The outlet pipe 131 allows water in the water storage chamber 134 to drain. The baffle 135 diverts water entering the water storage chamber 134, effectively guiding the flow when condensate is generated quickly, thus improving the stability of the drip surface 132 in terms of drainage. The first inclined surface 136 and the second inclined surface 137 prevent excessive condensate residue in the water storage chamber 134, increasing the maximum condensate flow rate that the water collection tank 130 can handle. The height of the outlet pipe 131 allows condensate in the second water channel 134b to drain smoothly. The design of the first water inlet channel 134a and the second water inlet channel 134b allows condensate to be smoothly discharged from the water storage chamber 134, ensuring the normal operation of the portable air conditioner 100. The arc-shaped design of the first water inlet channel 134a and the second water inlet channel 134b allows gravity to drive the condensate to flow without the need for external assistance, making the structure of the water storage chamber 134 simpler. The design of the groove 138 realizes the conversion of the condensate flow direction, avoiding the condensate from moving obliquely while shortening the flow distance of the condensate as much as possible, and realizing the rapid discharge of condensate.
[0115] [Seventh Embodiment]
[0116] See Figures 18 to 21 as well as Figure 31In one specific embodiment, the outer casing 110 is provided with a third air inlet 116 and a third air outlet 115. The third air inlet 116 cooperates with the second air inlet 211, and the third air outlet 115 cooperates with the second air outlet 231. A filter screen 300 is provided between the third air inlet 116 and the second air inlet 211. There is a gap 330 between the inner surface of the third air outlet 115 and the outer surface of the second air outlet 231. The gap 330 is set along the outer contour of the second air outlet 231 and forms an annular ventilation outlet.
[0117] The outer shell 110 has a third air inlet 116 and a third air outlet 115 on one side, which are arranged side by side. The upper shell 210 has a second air inlet 211 on the side near the third air inlet 116. The upper surface of the lower shell 230 and the lower surface of the middle shell 220 are joined together to form the second air outlet 231. The position of the second air inlet 211 is adapted to the position of the third air inlet 116 to ensure that the airflow passing through the third air inlet 116 can enter the second air inlet 211. 11. To facilitate heat exchange in the condenser heat exchanger 240, the position of the second air outlet 231 is adapted to the position of the third air outlet 115, ensuring that the airflow passing through the condenser heat exchanger 240 can be discharged from the third air outlet 115. Under normal circumstances, the outer contour of the third air inlet 116 is the same as that of the second air inlet 211, and the area of the second air inlet 211 is slightly smaller than that of the third air inlet 116. The adaptation relationship between the third air outlet 115 and the second air outlet 231 is the same, which will not be described in detail here.
[0118] When the portable air conditioner 100 is running, under the action of the fan inside the lower shell 230, the outside airflow flows into the upper shell 210 through the first air inlet. Before entering the upper shell 210, it passes through the filter screen 300. At this time, the filter screen 300 can block pollutants outside the second air inlet 211, such as dust, small blades, etc., to prevent these pollutants from entering the second air inlet 211 and adhering to the fins of the condenser heat exchanger 240, thus affecting the heat exchange effect of the condenser heat exchanger 240.
[0119] It should be noted that the filter 300 has an improved design for the arrangement of through holes on its surface to maximize the airflow area at the third air inlet 116.
[0120] Preferably, a sponge pad can be provided on the rear side of the filter screen 300 to further filter impurities in the airflow.
[0121] In related technologies, the portable air conditioner 100 does not have a filter 300 at its air inlet. Although this ensures the airflow area at the air inlet, it also makes it easy for pollutants to be drawn in at the air inlet.
[0122] Furthermore, a gap 330 is provided between each side of the frame 123d of the second air outlet 231 and each side of the frame 123d of the corresponding third air outlet 115. Multiple gaps 330 are connected to form an annular ventilation outlet, allowing the heat generated by the condenser heat exchanger 240 and the fan to be discharged more smoothly.
[0123] It should be noted that the frame 123d of the third air outlet 115 has a certain length along the air outlet direction, and the gap 330 is usually formed between the inner side of the frame 123d of the third air outlet 115 and the outer side of the frame 123d of the second air outlet 231.
[0124] The third air inlet 116 and the second air inlet 211 are designed so that when the condenser assembly draws outside air into the portable air conditioner 100, it needs to pass through the third air inlet 116 and the second air inlet 211 in sequence. The filter screen 300 is designed so that the outside air is filtered when it passes through the third air inlet 116, reducing the amount of pollutants entering the second air inlet 211, ensuring the normal operation of the condenser assembly, and improving the heat exchange effect of the portable air conditioner 100 during operation. The multiple gaps 330 forming an annular ventilation outlet allow the heat inside the casing to be discharged more smoothly, further improving the operational stability of the portable air conditioner 100.
[0125] [Eighth Embodiment]
[0126] In one specific embodiment, the filter 300 includes: a filter panel 301 with a notch; a first snap-fit portion located on the side of the filter panel 301 near the condenser assembly, the first snap-fit portion being detachably connected to a third air outlet 115; and / or, the first snap-fit portion being detachably connected to a third air inlet 116; a filter frame 302 fixedly connected to the housing 110, the filter frame 302 having a mesh 303 inside; the first snap-fit portion includes: a first The first snap-fit member 310 is provided in the notch, and at least a portion of the first snap-fit member 310 extends toward the condenser assembly and has a bend at the end of the extension, so that the first snap-fit member 310 can be fastened to the third air outlet 115 by the bend; the second snap-fit member 320 extends toward the condenser assembly and has a buckle at the end of the extension, so that the buckle can be fastened to the third air outlet 115; the first snap-fit member 310 and the second snap-fit member 320 are located on opposite sides of the filter panel 301.
[0127] The filter panel 301 is detachably connected to the third air inlet 116 via the first snap-fit part. The size of the filter panel 301 is adapted to the size of the third air inlet 116. A gap is left around the filter panel 301 and the third air inlet 116 to facilitate the removal and installation of the filter panel 301. The filter panel 301 is provided with through holes arranged side by side and at intervals to ensure that the external airflow can pass through the filter screen 300. The first snap-fit part is fixed to the side of the filter panel 301 near the second air inlet 211. The first snap-fit part is connected to the rear side of the frame 123d of the third air inlet 116 to fix the filter panel 301. After fixing, the filter panel 301 is located inside the frame 123d of the third air inlet 116 and away from the side of the second air inlet 211.
[0128] During installation, the filter panel 301 is fixed by engaging with the third air inlet 116 through the first snap-fit part. When the filter panel 301 needs to be replaced or cleaned, the filter screen 300 can be removed by simply disassembling the first snap-fit part and the third air inlet 116. During the disassembly process, there is no need to disassemble the outer shell 110 or the base 180, which greatly improves the replacement efficiency of the filter screen 300.
[0129] It should be noted that the ways in which the filter panel 301 and the third air inlet 116 are connected include, but are not limited to: snap-fit, fastening, magnetic attraction, etc.
[0130] It should be noted that the filter 300 can also be installed at the third air outlet 115, and the installation method is the same as that at the third air inlet 116, which will not be described again here.
[0131] When installing the filter panel 301, tilt the filter panel 301 so that the second snap-fit piece 320 first enters the interior of the housing 110. Then rotate the filter panel 301 so that the buckle on the second snap-fit piece 320 engages with the frame 123d of the third air outlet 115. Then rotate the filter panel 301 inward along the snap-fit position of the second snap-fit piece 320 to engage the first snap-fit piece 310 with the frame 123d of the third air outlet 115, thus fixing the filter panel 301. The installation method of the filter panel 301 at the third air inlet 116 is the same, and will not be described again here.
[0132] When the filter panel 301 is being disassembled, the first snap-fit connector 310 is controlled by the notch to disengage from the frame 123d of the third air outlet 115. Then, the filter screen 300 is rotated outward until the second snap-fit connector 320 disengages from the frame 123d of the third air outlet 115, at which point the filter panel 301 can be removed.
[0133] The filter panel 301 effectively filters pollutants from the external airflow. The detachable design of the first snap-fit part and the third air inlet 116 makes daily maintenance of the filter screen 300 more convenient. The snap-fit design of the first snap-fit part 310 and the second snap-fit part 320 makes the connection between the filter screen 300 plate and the third air outlet 115 or the third air inlet 116 more stable. The notch design allows the first snap-fit part 310 to be easily disconnected, making the disassembly of the filter panel 301 more convenient.
[0134] [Ninth Embodiment]
[0135] In one specific embodiment, the first latching member 310 includes: a first latching segment 311, which extends horizontally along the notch toward the condenser assembly; a second latching segment 312, which is connected to the first latching segment 311 and is bent at the connection point, changing the extension direction of the second latching segment 312 to the opposite of the first latching segment 311, with the end of the second latching segment 312 extending to the notch; and a protrusion 313, which is disposed on the second latching segment 312 and is capable of contacting the third air outlet 115.
[0136] The first snap-fit component 310 is U-shaped in general. The first snap-fit segment 311 extends horizontally into the interior of the outer shell 110 and is provided with a bend at the end of the extension. At least part of the bend is located on the inner side of the inner surface of the frame 123d of the third air outlet 115. After the bend is bent at °, it extends outward from the second snap-fit segment 312 to a position flush with the outer surface of the filter panel 301. A protrusion 313 is provided at the bend. The protrusion 313 is obliquely arranged and snaps with the frame 123d of the third air outlet 115 through the oblique surface.
[0137] In the horizontally extended structure, there is a gap between the first snap-fit section 311 and the second snap-fit section 312 on the outside of the filter panel 301. The operator can squeeze the second snap-fit section 312 toward the first snap-fit section 311 to change the relative position of the second snap-fit section 312 and the first snap-fit section 311. When disassembling the filter panel 301, by squeezing, the protrusion 313 is separated from the frame 123d of the third air outlet 115, and the filter panel 301 is rotated outward to complete the disassembly.
[0138] After the clip is engaged with the frame 123d of the third air outlet 115, the operator can place their finger at the notch and then rotate the filter panel 301 inward to forcefully engage the protrusion 313 with the frame 123d of the third air outlet 115.
[0139] It should be noted that during the installation process, when the protrusion 313 is attached to the frame 123d of the third air outlet 115, the buckle of the second snap-fit 320 has already been snapped onto the frame 123d of the third air outlet 115 on the other side. Therefore, the length of the protrusion 313 does not need to be very long, it only needs to play an auxiliary fixing effect, and the oblique setting makes it easier to disassemble the first snap-fit section 311.
[0140] Normally, there are two second clips 320, which are arranged side by side in the vertical direction. The height of the first clip 310 is located in the middle of the two second clips 320. The filter panel 301 is fixed by the cooperation of the two buckles and the protrusion 313, which improves the stability of the filter panel 301.
[0141] The design of the first clip section 311 and the second clip section 312 allows the staff to completely disassemble the first clip section 310 at the notch. The design of multiple second clip sections 320 makes the filter panel 301 more securely fixed, thus improving the stability of the portable air conditioner 100.
[0142] [Tenth Embodiment]
[0143] See Figures 22 to 29 In one specific embodiment, the portable air conditioner 100 further includes: a mounting slot 510, which is disposed on the base 180. The mounting slot 510 is provided with a third snap-fit member 520 and a second snap-fit part 400. The second snap-fit part 400 is fixedly connected to the outer shell 110 and is located on the side of the outer shell 110 near the base 180. The second snap-fit part 400 is detachably connected to the mounting slot 510.
[0144] The portable air conditioner 100 connects the outer shell 110 to the base 180 via the second snap-fit part 400. The second snap-fit part 400 is fixed to the bottom 117 of the outer shell 110. A mounting groove 510 is provided on the upper surface of the base 180. A surrounding structure extending towards the center is provided on the right side of the mounting groove 510. An accommodating space is formed between the surrounding structure and the bottom surface of the mounting groove 510. The second snap-fit part 400 slides into the accommodating space from left to right. The side wall of the second snap-fit part 400 contacts the side wall of the mounting groove 510, thereby engaging the second snap-fit part 400 with the mounting part 500. A battery is provided inside the base 180 to provide power to the portable air conditioner 100.
[0145] When the outer casing 110 and the base 180 are assembled, there is friction between the side of the second snap-fit part 400 and the side of the mounting groove 510. After the snap-fit is completed, the relative position between the second snap-fit part 400 and the mounting groove 510 will not change as the portable air conditioner 100 moves. The connection method of directly inserting the second snap-fit part 400 into the mounting groove 510 makes the connection between the outer casing 110 and the base 180 more convenient.
[0146] It should be noted that the surrounding structure can be an accessory that is installed in the mounting slot 510 later, or it can be integrally formed with the base 180.
[0147] It should be noted that the second snap-fit part 400 can be integrally formed with the housing, or it can be connected by a fixed connection.
[0148] In related technologies, during the assembly process, a connector is provided in the mounting groove 510 of the base 180, and a sliding groove is provided on the outer shell 110. The assembly of the outer shell 110 and the base 180 is achieved by the sliding groove cooperating with the elastic element. However, during the assembly process, after the sliding groove on the base 180 enters the mounting groove 510, it needs to be adjusted to a suitable position before it can be connected with the connector. The base 180 needs multiple sets of sliding grooves and elastic elements to cooperate simultaneously to be fixed. Moreover, the situation inside the mounting groove 510 cannot be observed during assembly, which makes the assembly between the outer shell 110 and the base 180 inconvenient.
[0149] Furthermore, the mounting groove 510 is provided with a first connecting hole 511, and the mounting part 500 also includes a third snap-fit member 520, which is detachably connected to the first connecting hole 511. A stop plate 521 is provided on the side of the third snap-fit member 520 away from the first connecting hole 511, and the second snap-fit part 400 is in contact with the lower surface of the stop plate 521.
[0150] The third snap-fit component 520 is fixedly connected to the inside of the mounting groove 510. A first connecting hole 511 is provided on the right side of the bottom of the mounting groove 510. The first connecting hole 511 is a through hole. The third snap-fit component 520 is U-shaped and hollow inside, accommodating the second snap-fit part 400 through a semi-enclosed structure. A connecting rod is provided at the lower end of the third snap-fit component 520, which is inserted into the first connecting hole 511 to fix the third snap-fit component 520 to the mounting groove 510. A step 512 is also provided between the left and right sides of the third snap-fit component 520. The step 512 is positioned at a length equal to that of the third snap-fit member 520 in the left-right direction, and the height of the step 512 is equal to the thickness of the third snap-fit member 520. After the third snap-fit member 520 is fixed, the lower surface of the mounting groove 510 is flat. The stop plate 521 is located on the side of the third snap-fit member 520 near the bottom of the shell 117. The stop plate 521 extends from the front and rear sides of the third snap-fit member 520 towards the middle. The stop plate 521 can restrict the second snap-fit part 400 from leaving the third snap-fit member 520, thus playing a stopping role.
[0151] The side of the third latching member 520 is attached to the side of the second latching part 400, and the position of the second latching part 400 is fixed by friction. When the magnitude of the friction is constant, the second latching part 400 cannot separate the outer shell 110 from the base 180 by moving left and right, thus avoiding the problem of frequent separation between the outer shell 110 and the base 180 when the portable air conditioner 100 is moved.
[0152] When the battery needs to be replaced, first remove the outer casing 110 from the base 180, and then remove the third clip 520 from the mounting slot 510. In this way, there is no structure to avoid when removing the base 180, making the battery replacement smoother. In related technologies, a corresponding connection structure to the outer casing 110 is provided in the mounting slot 510, which makes it inconvenient to remove the base 180 when replacing the battery.
[0153] Furthermore, the second snap-fit portion 400 includes: a connecting seat 410, at least a portion of which enters the mounting groove 510, and the upper surface of the connecting seat 410 is in contact with the inner surface of the stop plate 521; a boss 420, which is fixedly connected to the upper surface of the connecting seat 410, and the boss 420 is provided with a second connecting hole 421; and a fastener 430, one end of which is located inside the housing 110, and the other end of which is located inside the second connecting hole 421.
[0154] The outer contour of the connector 410 fits into the inner contour of the third snap-fit component 520. The upper section of the connector 410 is straight groove and the lower section is tapered. The boss 420 is located on the upper surface of the connector 410. The boss 420 is provided with two second connecting holes 421. The second connecting holes 421 are threaded holes. Each second connecting hole 421 corresponds to the through hole of the shell bottom 117. The fastener 430 is usually a screw. The screw passes through the shell bottom 117 from the inside of the shell 110 and engages with the second connecting hole 421 to complete the fixation between the boss 420 and the shell 110.
[0155] When the outer shell 110 is connected to the base 180, the right edge of the connecting seat 410 is in contact with the inner surface of the third snap-fit member 520. The boss 420 is located in the middle of the two side stop plates 521, that is, the boss 420 does not contact the stop plate 521, but the stop plate 521 can contact the upper surface of the connecting seat 410. That is, when the outer shell 110 moves upward as a whole, the boss 420 will not interfere with the third snap-fit member 520, but the connecting seat 410 can contact the stop plate 521 and drive the base 180 to move upward as a whole.
[0156] Furthermore, the boss 420 includes: a first protrusion 422, which engages with the connecting seat 410; and a second protrusion 423, which engages with the first protrusion 422 and is located on the side of the first protrusion 422 away from the connecting seat 410; the volume of the first protrusion 422 is larger than the volume of the second protrusion 423, and the second connecting hole 421 penetrates through the first protrusion 422 and the second protrusion 423.
[0157] The outer edge of the first protrusion 422 is tangent to the outer edge of the connecting seat 410. The outer contour of the second protrusion 423 is the same as that of the first protrusion 422. The second protrusion 423 is located at the center of the first protrusion 422. The fastener 430 passes through the first protrusion 422 and the second protrusion 423 in sequence along the second connecting hole 421 to complete the fixation of the second snap-fit part 400 and the outer shell 110.
[0158] The height of the upper surface of the second protrusion 423 is higher than the height of the upper surface of the stop plate 521. When the outer shell 110 and the base 180 are engaged, the first protrusion 422 enters the groove 138 inside the shell, and the upper surface of the second protrusion 423 contacts the lower surface of the shell, so as to prevent the shell from directly contacting the third snap-fit 520 and causing damage to the third snap-fit 520.
[0159] Furthermore, there is a first gap between the side of the connector 410 away from the housing 110 and the inner surface of the snap-fit groove, through which the base 180 and the housing 110 can be disassembled.
[0160] After the outer casing 110 and the base 180 are engaged, there is a first gap between the lower surface of the connecting seat 410 and the lower surface of the mounting groove 510. When the portable air conditioner 100 is working normally, the first gap always exists. When the outer casing 110 and the base 180 need to be disassembled, the second snap-fit part 400 is moved toward the first gap by external force. The second protrusion 423 and the first protrusion 422 can pass smoothly through the gap between the two side stop plates 521. After the connecting seat 410 contacts the base 180 of the third snap-fit part 520, the outer casing 110 is moved to the left to complete the disassembly.
[0161] Furthermore, the base 180 also includes a foot pad 181, which is located on the side of the base 180 near the outer casing 110 and is arranged side by side with the mounting groove 510.
[0162] Normally, the number of foot pads 181 is the same as the number of mounting slots 510, and they are arranged side by side in the mounting slots 510 near the center of the housing. When the housing 110 is disassembled from the base 180, the base 180 will move relative to the housing. At this time, the foot pads 181 can play a buffering role, reducing the impact force of the base 180 on the housing.
[0163] The cooperation between the mounting slot 510 and the second snap-fit part 400 makes it easier to fix the outer shell 110 and the base 180 directly. When the outer shell 110 and the base 180 are connected, the second snap-fit part 400 does not need to be aligned after entering the mounting slot 510. Assembly can be achieved simply by moving it, which improves the ease of assembly.
[0164] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
