DETAILED DESCRIPTION

[0036] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict in structure or function. The present application will be described in detail below according to examples.

[0037] The present application discloses a shell assembly, such as Figures 1 to 4As shown, the first inner frame support 120 has a first handle portion 123 at the upper portion, a first support section 121 extending downwardly forward from the front end of the first handle portion 123, and a second support section 122 extending downwardly backward from the rear end of the first handle portion 123, the first support section 121 and the second support section 122 are connected by a first connecting section 126 near the bottom plate 142, and the first connecting section 126 is connected to the bottom plate 142, the first handle portion 123, the first support section 121, the second support section 122 and the first connecting section 126 are integrally formed, and a stress deformation structure is formed between the first handle portion 123 and the first connecting section 126. Since the shell assembly is internally installed with a heavy object, when the first handle portion 123 is lifted under stress, the stress of the first handle portion 123 will be transmitted forward and backward to the first support section 121 and the second support section 122 connected thereto, and the stress will be transmitted to the stress deformation structure between the handle portion 123 and the first connecting section 126, so that the deformation of the stress deformation structure eliminates the stress generated on the first support section 121 and the second support section 122, preventing the first support section 121 and the second support section 122 from deforming due to stress in the long-term use, thereby affecting the stable pulling force on the bottom plate.

[0038] Thus, it is ensured that the two support sections generate a stable pulling force on the front and rear ends connected to the bottom plate 142 to smoothly lift the bottom plate 142 bearing the heavy object, and by connecting the first connecting section 126 at the lower end of the first support section 121 and the second support section 122, the pulling force of the first handle portion 123 is further formed in three sections to transmit to the bottom plate 142, generating a smooth upward pulling force on the bottom plate 142, thereby ensuring the stability of the entire classroom assembly in supporting the internal heavy object.

[0039] Specifically, in some embodiments of the present application, as shown in Figures 2 to 4 The stress deformation structure includes an opening arranged between the first handle portion 123 and the first connecting section 126, and a side plate elastically deformed and clamped with the opening, i.e. Figure 2The first side plate 148 is provided with and covers the opening. The first support segment 121 and / or the second support segment 122 facing the first side plate 148 are provided with a snap-fit ​​structure. The first connecting segment 126 facing the first side plate 148 is provided with a snap-fit ​​structure and / or a fastening connection structure. The first side plate 148 has a matching structure corresponding to the snap-fit ​​structure and the fastening connection structure. The first side plate 148 is a decorative panel for appearance. When the weight of the object on the base plate 142 is large, when the first handle part 123 is subjected to force, the first support segment 121 and the second support segment 122 connected to it will deform due to the tension. However, through the snap-fit ​​structure of the first side plate 148 covering the opening and the first support segment 121 and the second support segment 122, the deformation will be eliminated at the gaps of these snap-fit ​​structures, and the first side plate 148 will not be deformed, thereby ensuring the appearance consistency of the whole machine where the housing assembly is located.

[0040] In some embodiments of the present invention, the housing assembly further includes a front panel 141, which has a connecting edge for connecting to the base plate 142. The front panel 141 is also provided with a connecting structure for connecting to the front side of the first support segment 121, and the connecting structure on the front side of the first support segment 121 is correspondingly provided with a mating structure. A support decorative strip is also provided outside the connecting structure. Figure 2 The first decorative strip 143 covers the connecting structure and snaps onto the first bracket segment 121 and / or the front panel 141. The front panel 141 and the first bracket segment 121 are connected via a snap-fit ​​structure. In this embodiment, the front panel 141 is curved, and the connecting edge to the first bracket segment 121 is also curved, thus enhancing the aesthetics of the front panel 141. Furthermore, the curved edge increases the length of the connecting structure with the first bracket segment 121, thereby strengthening the reliability of the connection. The first decorative strip 143 can be snapped onto the connecting surface of the connecting structure, thus concealing the snap-fit ​​structure beneath it and enhancing the overall aesthetics of the device.

[0041] In some embodiments of the present invention, the second support segment 122 has a frame forming a tail opening. This frame includes vertically arranged upright ribs 127 and horizontal ribs 128 extending horizontally along the rear edge of the base plate 142. The second support segment 122 extends rearward and is integrally connected to the upright ribs 127. The second support segment 122 extends downward and is integrally connected to the horizontal ribs 128. The horizontal ribs 128 and the upright ribs 127, together with the curved section in the rearward downward segment of the second support segment 122, form a frame with a central opening, which allows the entire machine to perform its function.

[0042] In some embodiments of the present application, the first inner frame support 120 is further provided with a second connecting section 124, which forms a hollow handle passage with the first handle part 123, and the opening is located between the second connecting section 124 and the first connecting section 126. The second connecting section 124 is formed with a clamping structure connected with the first side plate 148, and the second connecting section 124 is connected with the first support section 121 and the second support section 122 and is integrally formed. The two ends of the second connecting section 124 are connected with the first support section 121 and the second support section 122, so as to form a substantially quadrilateral shape by the first connecting section 126, the second connecting section 124, the first support section 121 and the second support section 122. In this way, when the handle part is stressed to form force transmission, the strengthening of the bearing capacity is realized through the quadrilateral shape, so that the bottom plate 142 connected therewith can bear heavier objects. The four perimeters of the first side plate 148 are connected with the above-mentioned quadrilateral shape through the clamping structure, so that when the quadrilateral shape is deformed due to the stress of the handle part, more deformation is eliminated through the joint gap of the clamping structure, so that the first side plate 148 does not deform, so as to increase the appearance and not affect the appearance when the handle part is stressed.

[0043] In some embodiments of the present application, the second inner frame support 130 is symmetrically arranged with the first inner frame support 120, forming a corresponding second handle part, a first support section, a second support section, a first connecting section and a second connecting section, and being connected to the bottom plate 142, the front panel 141 and the side plate, i.e. the second side plate 151. Correspondingly, the second inner frame support 130 is further provided with a second decorative strip 144 corresponding to the position of the first decorative strip 143, which plays the same role as the first decorative strip 143. The side of the first handle part 123 is formed with a plug-in structure, which is connected with the plug-in structure formed on the side of the second handle part 131 to form the handle part 101. A passage bottom cover 152 is further provided, which forms a handle passage with the handle part 101, and the left and right sides thereof are connected to the second connecting section 124 of the first inner frame support 120 and the second connecting section of the second inner frame support 130, respectively. In this way, the first inner frame support 120 and the second inner frame support 130 are symmetrically arranged to form a hollow three-dimensional frame structure, so that heavy parts can be arranged in the hollow part. The handle part 101 is formed into a hollow tubular structure through the plug-in structure for convenient holding. When the handle part 101 is lifted, the stress is uniformly transmitted to the second inner frame support 130 and the first inner frame support 120 on both sides, and the two inner frame supports are connected with the bottom plate 142 to realize reliable tension on the bottom plate 142 to stably lift the whole machine.

[0044] Further, a handle decoration strip 145 is further included, which is used to cover the insertion structure of the handle part of the first inner frame support 120 and the second inner frame support 130, and is clamped with the handle part 101. Thus, the insertion structure is hidden under the handle decoration strip 145, and the appearance consistency of the whole machine where the shell assembly is located is enhanced.

[0045] In some embodiments of the present application, the first support section 121 and the second support section 122 include an outward exposed surface 125, which is located between the first decoration strip 143 and the first side plate 148, is connected with the handle part and extends in the rear direction of the handle, and extends to the bottom plate 142. The exposed surface 125 forms a smooth decoration surface, which, together with the decoration strip and the first side plate 148, forms the outer surface of the whole shell formed by the shell assembly, so that the shell appearance forms a whole, and the outer surface of the exposed surface 125 can adopt a color different from that of the decoration strip and the first side plate 148, thereby enhancing the beauty of the appearance formed by different colors.

[0046] In some embodiments of the present application, as shown in Figures 5 to 7 The stress deformation structure is an air inlet grille 132 arranged between the first handle part 123 and the first connecting section 126; the grille is formed in an elongated shape with a length of at least 1 / 3 to 3 / 4 of the side length, and includes vertically arranged grilles 132b arranged at intervals and integrally connected to the upper and lower structures of the shell, and the surface connected with the vertical grilles 132b is formed in an opening form with an outer width and an inner narrowness. The air inlet grille 132 is integrally connected with the first handle part 123 and the first connecting section 126, as shown in Figure 5As shown, the air inlet grille 132 is arranged in the middle region of the first handle part 101123 and the first connecting segment 126, and the air inlet grille 132 is integrally connected with the first handle part 123 and the first connecting segment 126 in the up-down direction through the overall plate surface, so as to realize the strength reliability of the entire shell assembly. Specifically, the air inlet grille 132 includes spaced grid segments, each grid segment includes two concave segments, i.e., an upper concave segment 132a and a lower concave segment 132c, which are concave towards the shell assembly, and a vertical grid 132b connecting the two segments, and the three segments are integrally connected to form a grid segment. The grid segments are spaced and preferably uniformly spaced in the front-rear direction to form the air inlet grille 132. The above-mentioned air inlet grille 132 is arranged in the first inner frame support 120, and the second inner frame support 130 can also be arranged with the same air inlet grille 132, so as to form a symmetrical distribution on the left and right sides of the shell assembly. When the handle part 101 is lifted under force, the weight inside the shell assembly of the handle part 101 generates stress under force, which is transmitted to the inner frame support, so that the grid segments of the air inlet grille 132 are slightly deformed to eliminate the stress. Specifically, the upper concave segment 132a and the lower concave segment 132c are deformed and elongated relative to the vertical grid 132b, so as to eliminate the stress and avoid the deformation of the inner frame support under long-term stress, thereby affecting the stability of the entire shell assembly in bearing the weight. Preferably, the length of the grid is 1 / 3 to 2 / 3 of the length of the side surface, so as to maintain the overall appearance of the shell assembly and ensure that it can bear stress.

[0047] The present application also provides a portable air conditioner (hereinafter referred to as air conditioner), which comprises a refrigerant system and the shell assembly provided in the above embodiments, such as Figures 1 to 9 As shown, the shell assembly forms the shell 199 of the air conditioner, and the inside is a hollow cavity. The inner cavity is provided with a refrigerant system to form the main body 100 of the air conditioner. Specifically, the bottom plate 142 is provided with a compressor 107, a condenser heat exchanger 106 connected with the exhaust port of the compressor 107, an evaporator heat exchanger 109 connected with the suction port of the compressor 107, and further includes an air inlet fan 108, a throttling device and an air outlet fan 117. The compressor 107, the condenser heat exchanger 106, the evaporator heat exchanger 109 and the throttling device are sealingly connected through the refrigerant pipe, so as to form the refrigerant system. The front side of the front panel 141 is provided with an air outlet 102 inclined upward and an air inlet 103 close to the air outlet 102. The rear side of the shell 199 is provided with a condensing air inlet 105 and a condensing air outlet 104, which are respectively formed by the surrounding frame of the first inner frame support 120 and the surrounding frame of the second inner frame support 130.

[0048] The air conditioner further comprises a battery shell arranged below the shell 199, which is connected with the shell 199 through a connecting structure, and a battery module is arranged in the battery shell to form a battery box 600, so as to supply power for the operation of the control system in the shell 199, and an electric control box 161 is further arranged in the shell 199 to control the operation of the air inlet fan 108, the compressor 107 and the air outlet fan 117.

[0049] The air outlet 102 and the air inlet 103 are specifically arranged on the front panel 141, and the surrounding frames of the first inner frame support 120 and the second inner frame support 130 form the condensation air inlet 105 and the condensation air outlet 104, respectively, which together with the condensation heat exchanger 106 and the air outlet fan 117 form a condensation air duct, and the airflow in the condensation air duct exchanges heat with the condensation heat exchanger 106 to take away the heat on the condensation heat exchanger 106.

[0050] In some embodiments of the present application, as shown in Figure 2 The fixed ring 149 is sleeved on the outer wall surface of the surrounding frames of the first inner frame support 120 and the second inner frame support 130 to fix the two surrounding frames symmetrically, and two air pipe connecting rings 147 corresponding to the two surrounding frames are further arranged, the size of the air pipe connecting ring 147 is adapted to the size of the surrounding frame, a clamping structure is formed between the air pipe connecting ring 147 and the surrounding frame, and the two are fixed in the fixed ring 149, the two air pipe connecting rings 147 are located around the condensation air inlet 105 and the condensation air outlet 104, respectively, to connect the condensation air inlet hose (not shown in the figure) and the condensation air outlet hose (not shown in the figure), respectively, to realize long-distance air inlet and long-distance air outlet during heat exchange of the condenser. The condensation filter screen 146 can be further arranged at the condensation air inlet 105 and the condensation air outlet 104, respectively, and the condensation filter screen 146 is arranged between the wall surface of the first inner frame support 120 and the second inner frame support 130 and the fixed ring 149 to filter impurities in the air inlet and the air outlet, and also prevent foreign matters from extending into the shell 199 to damage the components inside the shell 199.

[0051] In some embodiments of the present application, the portable air conditioner comprises a portable state and a placed state. The stress deformation structure of the first inner frame support 120 is arranged in the opening between the first handle part 123 and the first connecting section 126. When the portable air conditioner is switched from the placed state to the portable state, the handle part 101, the first support section 121 and the second support section 122 are elastically deformed, and the at least one clamping structure connected between the first support section 121 and the second support section 122 of the first side plate 148 is elastically deformed or slid.

[0052] In some embodiments of the present application, the portable air conditioner comprises a portable state and a placed state. When the portable air conditioner is switched from the placed state to the portable state, the handle part 101, the first support section 121 and the second support section 122 are elastically deformed, and the at least one clamping structure connected between the first support section 121 and the second support section 122 of the first side plate 148 is elastically deformed or slid. When the handle part 101 is stressed by the user, the weight of the components of the refrigerant system arranged on the bottom plate 142 of the handle part 101 causes the handle part 101 and the first support section 121 and the second support section 122 connected thereto to be deformed. The first side plate 148 of the first support section 121 and the second support section 122 is elastically deformed or slid due to the small gap of the clamping structure at the connection, so that the stress generated on the first support section 121 and the second support section 122 is eliminated, and the deformation is not transmitted to the first side plate 148 as an appearance part, and the consistency of the appearance of the entire air conditioner is ensured.

[0053] The stress deformation structure of the second inner frame support 130 is the same as that of the first inner frame support 120, and the principle of eliminating stress is the same as that of the first inner frame support.

[0054] The handle part 101 is arranged at the position of the center of gravity of the air conditioner, which is convenient for stability during portability. The length of the handle part 101 is preferably greater than the width of the hand of the user, for example, the length of the handle part 101 is twice the width of the hand of the user, so that the air conditioner is conveniently lifted by holding the handle part 101 with one hand or both hands.

[0055] When the portable air conditioner is switched from the placed state to the portable state, the handle part 101, the first support section 121 and the second support section 122 are elastically deformed, and the channel bottom cover 152 respectively supports the second connecting section 124 of the first inner frame support 120 and the second connecting section 124 of the first inner frame support 120.

[0056] In some embodiments of the present application, the force-deformation structure of the first inner frame support is an air inlet grille arranged between the first handle and the first connecting section, and when the air conditioner is switched from the placed state to the portable state, the handle, the first support section and the second support section are elastically deformed, and the vertical grille of the air inlet grille is elongated, and the opening of the surface connected with the vertical grille is widened. Specifically, the upper concave section and the lower concave section of the grille section are elongated to eliminate the stress caused by the force, thereby avoiding the deformation of the inner frame support caused by the long-term force, thereby affecting the stability of the entire shell assembly in bearing the weight, and further avoiding the deformation of the entire air conditioner, thereby affecting the appearance and enhancing the firmness of the entire shell body of the air conditioner.

[0057] The force-deformation structure of the second inner frame support 130 is the same as that of the first inner frame support 120, and the principle of eliminating stress is the same as that of the first inner frame support.

[0058] The present application discloses a portable air conditioner (hereinafter referred to as air conditioner), as shown in Figures 8 to 20 The air conditioner comprises a bottom plate 142 and a shell fixedly connected with the bottom plate 142 to form an internal mounting cavity for mounting components of the air conditioner, wherein an evaporative heat exchanger 109 is arranged on the front side of the bottom plate 142, and a condensing heat exchanger 106 is arranged on the rear side of the bottom plate 142, and a water collecting tray 162 is further arranged, which has a first water collecting section 1621 arranged below the evaporative heat exchanger 109, and is inclined from front to back, and is located above the bottom plate 142 with a certain interval. The periphery of the water collecting tray 162 is a vertical wall surface to form a water containing cavity, so that the water collecting tray 162 is arranged below the evaporative heat exchanger 109 to collect the condensed water generated by the evaporative heat exchanger 109 during refrigeration, and the condensed water is prevented from directly flowing onto the bottom plate 142, and the water collecting tray 162 and the bottom plate 142 are spaced apart. Figure 20As shown, the distance between the water pan 162 and the bottom plate 142 is set to be 0.5cm to 5cm, so that there is an air gap between the water pan 162 and the bottom plate 142, so that the low temperature of the condensed water on the water pan 162 will not be transmitted to the bottom plate 142, so as not to cause the temperature of the bottom plate 142 to be reduced to produce condensation phenomenon, even if condensation is generated on the outer surface of the water pan 162, the water amount of the small water droplets generated by the condensation is much less than that of the condensed water, even if it drops to the bottom plate 142, the very small amount of water will be evaporated by the bottom plate 142 which has a relatively high temperature, and will not cause substantial temperature reduction of the bottom plate 142. Moreover, the water pan 162 is set to be inclined from the front side of the evaporative heat exchanger 109 to the rear side of the condensing heat exchanger 106, so that the condensed water dropped from the evaporative heat exchanger 109 can be quickly flowed away by the water pan 162, and will not be accumulated at the position of the first water receiving section 1621 to cause overflow phenomenon.

[0059] In some embodiments of the present application, the water pan 162 further comprises a second water receiving section 1622, which is a narrow sheet shape, and is arranged below the refrigerant pipeline, which is a pipeline connecting the suction pipe of the compressor 107 to the evaporative heat exchanger 109, and specifically Figure 3The refrigerant pipe connecting section 164 is shown in the middle. According to the working principle of the air conditioner, the gaseous refrigerant with high temperature and high pressure from the discharge port of the compressor 107, after passing through the condensing heat exchanger 106 to discharge heat to the outside to cool the refrigerant in the refrigerant pipe, becomes liquid refrigerant with low temperature and high pressure, and after throttling and pressure reduction by the throttling and pressure reduction component such as the capillary tube 163, becomes liquid refrigerant with medium temperature and high pressure, and then enters the evaporating heat exchanger 109. The evaporating heat exchanger 109 absorbs heat from the surrounding environment to lower the temperature, and the temperature of the refrigerant passing through the evaporating heat exchanger 109 is very low, so that the temperature of the fins of the evaporating heat exchanger 109 installed on the refrigerant pipe is also very low, thus causing condensate water to be generated and to drip to the first water receiving section 1621 of the water pan 162 below the evaporating heat exchanger 109. After exiting the evaporating heat exchanger 109, the refrigerant becomes gaseous refrigerant with low temperature, and finally enters the suction port of the compressor 107 to be compressed by the compressor 107 into high-temperature and high-pressure refrigerant, thus forming a cycle. Therefore, the refrigerant pipe connecting the inlet and outlet of the evaporating heat exchanger 109 also absorbs heat from the outside, so that the temperature of the refrigerant pipe is very low, generally below 2°, and therefore this section of the refrigerant pipe is also prone to generate condensate water, especially the refrigerant pipe connecting section 164 connecting the suction port of the compressor 107, and the refrigerant pipe connecting section between the evaporating heat exchanger 109 and the condensing heat exchanger 106, which is mainly a capillary tube 163, has a much smaller diameter than the refrigerant pipes at other positions, so that less condensate water is generated and is not easy to drip. Therefore, the refrigerant pipe connecting section 164 connecting the suction port of the compressor 107 is first selected to be arranged above the water pan 162, i.e. above the second water receiving section 1622, to receive the dripping condensate water. Further, the refrigerant pipe section between the evaporating heat exchanger 109 and the condensing heat exchanger 106, i.e. the capillary tube 163, is also arranged above the second water receiving section 1622, to reduce the phenomenon of condensate water dripping onto the water pan 162.

[0060] In some embodiments of the present application, the water pan 162 is provided with a positioning and connecting structure which gradually reduces the spacing between the water pan 162 and the bottom plate 142 from the front side to the rear side. As shown in Figures 11 to 13As shown, a plurality of fixing blocks 165 are arranged on the bottom plate 142, and the water collecting tray 162 is installed on the fixing blocks 165. Specifically, a long strip-shaped fixing block 165 is arranged under the first water collecting section 1621, two small square fixing blocks 165 are arranged under the second water collecting section 1622, and a structure for fixing the water collecting tray 162, such as a fixing column, can be arranged on one or all of the fixing blocks 165, so as to facilitate the fixation of the water collecting tray 162 on the fixing blocks 165 by means of fasteners such as screws. By reasonably adjusting the height of the fixing blocks 165, the height of the water collecting tray 162 from the front of the evaporative heat exchanger 109 to the rear of the condensing heat exchanger 106 gradually decreases, that is, the gap between the water collecting tray 162 and the bottom plate 142 gradually decreases in the above direction, so as to form a slope downward from the front to the rear on the surface of the water collecting tray 162, thereby enabling the condensed water dropped from the evaporative heat exchanger 109 to be smoothly drained without being accumulated in the first water collecting section 1621.

[0061] In some embodiments of the present application, the water collecting tray 162 is spaced apart from the heat exchanger fins of the evaporative heat exchanger 109, the heat exchanger fins are arranged in the front-rear direction, and the condensed water is dropped from the evaporative heat exchanger 109 to the water collecting tray 162 and flows out of the first water collecting section 1621 along the gap between the water collecting tray 162 and the fins, thereby achieving the smooth drainage of the condensed water. Here, the fins of the evaporative heat exchanger 109 are arranged in parallel in the front-rear direction, and the air inlet fan 108 is arranged on one side of the evaporative heat exchanger 109 in the front-rear direction, specifically as shown in Figure 20 As shown, the air inlet fan 108 is arranged on the rear side of the evaporative heat exchanger 109, so that when the air inlet fan 108 is working, the air from the outside enters the evaporative air inlet 103 in the front-rear direction, is cooled by the fins, and is then discharged from the evaporative air outlet 102, so as to achieve the refrigeration of the surrounding air. At the same time, the condensed water generated on the fins and the refrigerant pipe of the evaporative heat exchanger 109 flows down along the surface of the fins and drops to the first water collecting section 1621, and is drained along the second water collecting section 1622 in the front-rear inclined direction.

[0062] In some embodiments of the present application, as shown in Figure 12As shown, the second water receiving section 1622 has a frame forming the tail opening, which includes vertical studs and horizontal bars extending horizontally along the two sides of the bottom plate 142. The first water receiving section 1621 forms a water receiving cavity with vertical walls around it, and is arranged in a long strip shape in the left-right direction to match the bottom surface of the evaporative heat exchanger 109. The second water receiving section 1622 connected thereto is arranged in a long strip shape in the front-back direction, and has vertical walls formed by the studs on the two sides thereof. The bottom thereof has horizontal bars extending along the front-back direction of the bottom plate 142, and the studs extend downward and are integrally connected with the horizontal bars to form a frame. The second water receiving section 1622 is substantially at a right angle with the first water receiving section 1621. One end of the stud at the rear part is provided with a connecting structure with the rear part of the bottom plate 142, specifically, a fixed lug 171 close to the horizontal bar and located between the two studs. A screw hole is arranged in the middle of the fixed lug 171, and a fixed column is arranged on the bottom plate 142 at a corresponding position, so that the fixed lug 171 is fixed on the fixed column by a screw, thereby fixing the second water receiving section 1622 on the bottom plate 142. A water collecting cavity 168 surrounded by vertical walls is further arranged below the condensing heat exchanger 106 on the bottom plate 142. One side of the water collecting cavity 168 is connected with the second water receiving section 1622 to collect the condensed water flowing out of the second water receiving section 1622. The water collecting cavity 168 is arranged below the condensing heat exchanger 106, which is used to evaporate the water in the water collecting cavity 168 to some extent to reduce the water level, because the temperature of the condensing heat exchanger 106 is relatively high compared with the ambient temperature when the air conditioner is working. A drain hole 167 is further arranged at the rear end of the bottom plate 142. The drain hole 167 is blocked by a rubber plug during normal working, and the rubber plug is pulled out when the user needs to drain water, so that the water in the water collecting cavity 168 is drained. Alternatively, a drain pipe (not shown in the figure) can be further arranged to be connected with the drain hole 167, so that the water in the water collecting cavity 168 is drained to a remote position, such as a large water tank.

[0063] Further, a water beating wheel (not shown in the figure) can be arranged in the water collecting cavity 168 to beat the water in the water collecting cavity 168 to the surface of the fins of the condensing heat exchanger 106, so that the water is quickly evaporated by the high-temperature fins, thereby accelerating the evaporation of the water in the water collecting cavity 168.

[0064] In some embodiments of the present application, as Figures 8 to 20As shown, the bottom plate 142 is also provided with a compressor 107, and the compressor 107 is connected through a damping device. The bottom plate 142 is also provided with ribs and / or grooves to increase the structural strength of the bottom plate 142, so as to increase the strength of the bottom plate 142, thereby bearing heavy devices such as the compressor 107, the condenser heat exchanger 106, the evaporator heat exchanger 109, and the fan assembly, and maintaining the strength of the bottom plate 142 during transportation. Since the large area of the bottom plate 142 is not accumulated with condensed water, condensation will not be caused by the low temperature of the condensed water. Therefore, the upper and lower surfaces of the bottom plate 142 do not need to be provided with a thermal insulation layer such as thermal insulation sponge, and the upper and lower surfaces are smooth plastic surfaces, thereby reducing the installation process of the bottom plate 142 which needs to be attached with thermal insulation sponge.

[0065] In some embodiments of the present application, the portable air conditioner further comprises a housing 199 connected with the bottom plate 142, the housing 199 is provided with a handle portion 101, the handle portion 101 is provided with a key panel 170 and a display panel 169, the bottom plate 142 is provided with a water retaining rib 166 on the other side of the water collecting cavity 168 to form a water retaining area, and an electric control box 161 is installed in the housing 199 at the position of the water retaining area. The electric connection lines (not shown in the figure) between the key panel 170, the display panel 169, and the electric control box 161 are routed at the position of the water retaining area. Figures 8 to 20 As shown, the handle portion 101 is arranged above the housing 199, so as to facilitate holding the handle portion 101 to carry the air conditioner. The front and rear portions of the housing 199 at the position of the handle portion 101 are provided with a plurality of feet 102, so as to facilitate the air conditioner to stand on the ground. Figure 11 Figure 14 Figures 16 to 18 As shown, the key panel 170 and the display panel 169 are arranged, wherein the key panel 170 is arranged in front of the handle portion 101, and the display panel 169 is arranged behind the handle portion 101. The key panel 170 is used to set the operation mode, wind speed, and other functions of the air conditioner. Indicating lights can also be arranged on the key panel 170 to indicate the respective operation modes. The display panel 169 can display the current operation state of the air conditioner or the amount of power of the battery in the battery box 600 connected below the air conditioner. The area on the bottom plate 142 adjacent to the water collecting cavity 168 is the position of the installation of the exhaust fan 117. In order to prevent the water in the water collecting cavity 168 from overflowing into the adjacent area when the water is high, causing water accumulation in other areas of the bottom plate 142, the water retaining rib 166 is arranged in the area of the installation of the exhaust fan 117, so as to limit the overflow of the condensed water in this area, and prevent the spread to other areas of the bottom plate 142. Since the electric control box 161 is installed in the area close to the second water collecting section 1622 of the water pan 162, as shown in Figure 12 and Figure 13 ​​As shown, the compressor 107 is installed at a position close to the center of the bottom plate 142, and the electric control box 161 and the second water receiving section 1622 are arranged on the two sides of the compressor 107 respectively. In order to prevent the water on the bottom plate 142 below the electric control box 161 from entering the electric control box 161 and causing the circuit board inside the electric control box 161 to be short-circuited and thus causing the air conditioner to malfunction, the area of the bottom plate 142 below the electric control box 161 should be kept dry as much as possible. Therefore, a water blocking rib 166 is further arranged in the area where the exhaust fan 117 is installed, so as to prevent the water overflowing from the water collecting cavity 168 from spreading to the area below the electric control box 161, thereby ensuring the safety of the electric control board inside the electric control box 161. Moreover, the distribution of the wiring of the connecting wires electrically connected to the circuit board and leading out of the electric control box 161 is arranged on the side opposite to the water collecting cavity 168 and the water pan 162, and the connecting wires are electrically connected to the key plate 170 and the display plate 169 as described above, i.e. Figure 3 the side of the middle bottom plate 142 away from the water collecting cavity 168 and the water pan 162, so as to be away from the water containing area on the bottom plate 142 such as the water pan 162 and the water collecting cavity 168, and to reduce the possibility of the connecting wires being contacted by the condensed water, thereby avoiding the condensed water from entering the electric control box 161, the key plate 170 and the display plate 169 along the connecting wires and causing the working failure problem, and thus improving the reliability of the operation of the entire air conditioner.

[0066] In some embodiments of the present application, the shell 199 is arranged in a long strip shape, and the evaporative heat exchanger 109, the compressor 107 and the condensing heat exchanger 106 are arranged from front to back. By arranging the shell 199 of the air conditioner in a long strip shape, compared with the vertical shape of the mobile air conditioner commonly seen on the market, the height of the air conditioner is greatly reduced and the bottom area is increased, which is beneficial to placing stably and reducing the risk of overturning, so as to facilitate carrying. Moreover, the refrigeration cycle components including the evaporative heat exchanger 109 and the heating cycle components including the condensing heat exchanger 106 are arranged on the two sides of the compressor 107 respectively, so that the center of gravity of the entire air conditioner is evenly distributed, which is more suitable for convenient carrying.

[0067] The shell 199 includes a front panel 141 arranged at the front thereof, and the upper part and the lower part of the front panel 141 are respectively provided with an evaporative air inlet 103 and an evaporative air outlet 102. The shell 199 and the inside of the shell 199 form an air duct connecting the evaporative air inlet 103 to the evaporative air outlet 102, and a filter screen, the evaporative heat exchanger 109 and the air inlet fan 108 are sequentially arranged on the air duct.

[0068] Further comprising an exhaust air duct, a condensing air inlet 105 is arranged at the rear end of the shell 199, and a condensing air outlet 104 is arranged side by side, an exhaust fan (not shown in the figure) is arranged on the exhaust air duct, air is sucked from the condensing air inlet 105, heated by the condensing heat exchanger 106, and then sucked into the exhaust fan, and then discharged from the condensing air outlet 104 under pressure. A handle part 101 is arranged on the upper surface of the shell 199 of the air conditioner, so that the entire air conditioner can be easily and stably lifted and carried by holding the handle part 101.

[0069] A battery box 600 connected to the bottom plate 142 can also be arranged below the air conditioner, and a battery module is installed inside to supply power to the operation of the air conditioner, so that the air conditioner can work in an external environment such as a field where it is inconvenient to provide power.

[0070] The application discloses a light-emitting assembly, such as Figures 1 to 20 As shown, the first PCB circuit board provided with the first light-emitting body 172, and the shell 199 with an appearance surface, the first light-emitting body 172 is arranged towards the shell 199, and the first PCB circuit board is arranged in the first area in the shell 199; the air duct shell 199 in a cooling state and / or the evaporative heat exchanger 109 in a cooling state, a cooling area is formed outside the air duct shell 199 and / or the evaporative heat exchanger 109; the first area and the cooling area are communicated. The shell 199 with an appearance surface makes the outside of the local shell have a smooth appearance surface, in order to better display the light transmission effect of the first light-emitting body 172, the appearance surface corresponding to the first light-emitting body 172 is locally thinned, or in the form of local transparency or semi-transparency, so as to facilitate the user's observation. The light-emitting assembly is arranged in the air conditioner, the air conditioner comprises an external shell 199 and a bottom plate 142 connected to the lower part of the shell 199, so as to form an internal mounting chamber for mounting the components of the air conditioner for refrigeration / heat operation, such as the evaporative heat exchanger 109, the air inlet fan 108, the compressor 107, the throttling component, the condensing heat exchanger 106, the exhaust fan 117 and other components, so that the air conditioner can perform refrigeration / heat operation. Because the evaporator works at a low temperature, a cooling area is formed around the evaporative heat exchanger 109 and the air duct shell communicated with the evaporative heat exchanger 109, the temperature of this area is lower than that of other areas in the shell 199, and the first light-emitting body 172 works and generates heat, so that the temperature of the first PCB circuit board is relatively high, which causes the temperature around it to rise, and the first area where the first light-emitting body 172 is located is communicated with the cooling area, so that the cold air in the cooling area flows downward due to convection, the air in the first area is supplemented, and the temperature of the first area is reduced, so as to realize the reliability improvement of the first PCB circuit board, and ensure that the temperature of the light-emitting body does not overheat, so as to improve the working reliability of the entire circuit board.

[0071] Specifically, in some embodiments of the present application, the shell 199 has a pattern on the area facing the light-emitting body, and when the light-emitting body is working, the illuminated pattern can be seen from the outside; the inside of the shell 199 has a touch sensor, which is located on the inner side of the shell 199 and is used to sense the touch signal at the pattern position; the touch sensor is a conductive sponge or a conductive spring 174, which is connected to a capacitance detection circuit and is connected to a touch chip through the capacitance detection circuit. As shown in FIG. 14, Figures 16 to 18 The first PCB circuit board is the key plate 170 in the figure, and the light-emitting body arranged on the key plate 170 is divided into two parts, one part is arranged inside the conductive spring 174 to serve as a touch key response corresponding to a function indication, and the other part is arranged on the other side of the key plate 170 to serve as a separate other function indication such as a wind speed indication. A thin plastic piece for a decorative strip is arranged above the key plate 170, and the surface of the decorative strip corresponding to the position of the conductive spring 174 is provided with a pattern, and the position is a light-transmissive area. When the corresponding pattern position is pressed, the conductive spring 174 transmits the sensing signal of the human hand to the touch sensing detection circuit on the key plate 170, which is detected in this way. For example, if the position is a cooling function key, it corresponds to a cooling mode pattern such as a snowflake pattern. When the position is touched by a human hand, the light-emitting body such as an LED lamp arranged inside the conductive spring 174 is lit, so that the corresponding pattern is lit. In this way, the air conditioner receives the key instruction of the cooling mode to run in the cooling mode, and the user can clearly know the running state of the air conditioner through the lighting of the pattern. When other keys such as wind speed keys are pressed, the air conditioner enters the wind speed setting state, and the corresponding pattern above the light-emitting body of the wind speed indication is also lit, so that the user can clearly know the current set wind speed. The above structure forms a gap between the inner surface of the shell 199 and the first PCB circuit board, so that air can enter from other positions to reduce the actual temperature of the first area.

[0072] In some embodiments of the present application, the first area is located on the upper side of the cooling area, and the descending air flow is formed in the cooling area, and the air of the first area joins the descending air flow. As shown in FIG. 15, Figure 16 The first area where the first PCB circuit board is located is located on the upper part of the shell 199, and the cooling area where the evaporator and the air inlet fan 108 are located is located on one side of the shell 199 and is close to the first area, so that the cooling area is cooled and descends, and the surrounding air including the relatively hot air of the first area is supplemented to form a convection gas, so that the relatively hot air of the first area is continuously taken away, and the air at other positions is supplemented, thereby playing a better cooling effect on the first area, thereby ensuring the working reliability of the first PCB circuit board.

In this way, through the symmetrical first inner frame support 120 and the second inner frame support 130, the shell 199 forms a hollow three-dimensional frame structure, so that a heavy component can be arranged in the hollow part. The handle portion 101 is formed into a hollow tubular structure through the plug-in structure to facilitate holding, when the handle portion 101 is held and lifted, the force is evenly transmitted to the second inner frame support 130 and the first inner frame support 120 on both sides, and through the connection of the two inner frame supports and the bottom plate 142, a pulling force is generated on the bottom plate 142 to stably lift the air conditioner. A handle decoration strip 145 is also arranged on the upper part of the handle portion 101, which is the decoration strip mentioned in the above embodiment, and is used to cover the plug-in structure of the handle portion of the first inner frame support 120 and the second inner frame support 130 and is clamped with the handle portion 101. Thus, the plug-in structure is hidden under the handle decoration strip 145, and the appearance consistency of the air conditioner is enhanced.

[0074] The first PCB circuit board is fixed in the handle portion 101 through a fixing portion arranged in the handle portion 101, as shown in the drawings Figure 6As shown, the specific fixing part includes front and rear clamping parts 175 and 176 respectively arranged in the first handle part 123 and the second handle part 131, which are composed of clamping ribs arranged upward and downward, so as to clamp the first PCB circuit board in the space formed between the upward and downward clamping ribs, and the conductive spring 174 mounted on the first PCB circuit board abuts against the bottom surface of the handle decoration strip 145, and the pattern of the air conditioner function is arranged on the surface of the handle decoration strip 145 corresponding to the position of the conductive spring 174, so as to realize the touch sensing signal detection of the user in this area. Further, the light emitting body such as the SMD LED is also mounted on the circuit board in the conductive spring 174, so as to control the LED to execute lighting or turning off when the touch chip of the first PCB circuit board detects that the button in this area is triggered, so as to realize the opening or closing of the corresponding air conditioner function. Further, the rear clamping part 176 is also formed with a plurality of light emitting cavities 177 surrounded by the clamping ribs, and the light emitting body is mounted on the first PCB circuit board in each light emitting cavity 177, and the part of the clamping rib abutting against the handle decoration strip 145 forms a light guide column, so as to guide the light of the light emitting body in the light emitting cavity 177 to the bottom surface of the part of the handle decoration strip 145 abutting against, and display the light on the surface of the handle decoration strip 145 through the transparent or semi-transparent material of the handle decoration strip 145, so as to realize the display of the corresponding air conditioner function, so as to be used for the wind speed display of the air conditioner, when the touch button of the set wind speed is triggered, the light emitting body indicating the wind speed level in the plurality of light emitting cavities 177 is lit, so as to realize the corresponding display of the wind speed level. Through the connection of the first inner frame support 120 and the second inner frame support 130, the first PCB circuit board is reliably clamped in the left and right directions, so as to be reliably fixed in the handle part 101.

[0075] The application also provides a portable air conditioner (hereinafter referred to as air conditioner), such as Figures 8 to 20 As shown, the light emitting assembly mentioned in the above embodiment is also provided, and a refrigerant circulation system arranged in the air conditioner is further provided, which is sequentially connected with an evaporative heat exchanger 109, a compressor 107, a condensing heat exchanger 106 and a throttling device; and the first PCB circuit board is arranged on one side of the evaporative heat exchanger 109. The shell 199 is in a strip shape, and the evaporative heat exchanger 109, the compressor 107 and the condensing heat exchanger 106 are arranged from front to back. By arranging the shell 199 of the air conditioner in a strip shape, compared with the vertical shape of the common mobile air conditioner on the market, the height of the air conditioner is greatly reduced and the bottom area is increased, which is beneficial to stable placement and reduces the risk of overturning, so as to facilitate carrying. The refrigeration cycle components including the evaporative heat exchanger 109 and the heating cycle components including the condensing heat exchanger 106 are arranged on both sides of the compressor 107, so that the gravity center of the whole air conditioner is uniformly distributed, which is more suitable for convenient carrying.

[0076] The shell 199 comprises a front panel 141 arranged at the front of the shell 199, the upper and lower portions of the front panel 141 are respectively provided with an evaporation air inlet 103 and an evaporation air outlet 102, the shell 199 and the shell 199 are internally formed with an air duct connecting the evaporation air inlet 103 to the evaporation air outlet 102, and a filter screen, an evaporation heat exchanger 109 and an air inlet fan 108 are sequentially arranged on the air duct;

[0077] The air outlet fan 117 is arranged on the air outlet duct, and the air outlet fan 117 sucks air from the condensation air inlet 105, heats the air through the condensation heat exchanger 106, and then sucks the air into the air outlet fan 117, pressurizes the air, and discharges the air from the condensation air outlet 104. A handle portion 101 is arranged on the upper surface of the shell 199 of the air conditioner, so that the entire air conditioner can be easily and stably lifted and carried by holding the handle portion 101.

[0078] The control box 161 is further arranged in the shell 199, and a control circuit board for controlling the air conditioner is arranged in the control box 161. The control circuit board, the key plate 170 and the display plate 169 are electrically connected (not shown in the figure), so that the key signal output value detected by the key plate 170 is output to the control circuit board. The control circuit board outputs corresponding control signals to control each electric control component of the air conditioner to work, realizes refrigeration or heating operation, and outputs display information to the display plate 169 to realize corresponding air conditioner function display.

[0079] A battery box 600 connected to the bottom plate 142 is further arranged below the air conditioner, and a battery module is arranged in the battery box 600 to supply power to the air conditioner, so that the air conditioner can work in an external environment where power supply is not convenient, such as a wild field.

[0080] In some embodiments, the condensation heat exchanger 106 is located away from one end of the evaporation heat exchanger 109, a temperature rising area is formed on the outside of the condensation heat exchanger 106 and / or the air duct shell 199 connected to the condensation heat exchanger 106, and an upward air flow is formed in the temperature rising area; and a mounting position of the compressor 107 is arranged between the evaporation heat exchanger 109 and the condensation heat exchanger 106. For example, Figures 8 to 20As shown, the evaporative heat exchanger 109 and the condensing heat exchanger 106 are respectively arranged at the front and rear of the inside of the shell 199, and the compressor 107 is arranged in the middle region. The air duct shell 199 connected with the condensing heat exchanger 106 is provided with an exhaust fan 117. Since the condensing heat exchanger 106 has a high temperature during the refrigeration operation, hot air is formed around the condensing heat exchanger 106 to form a temperature rising region. The hot air in the temperature rising region diffuses to the temperature falling region formed around the evaporative heat exchanger 109, is cooled, and then falls and flows back to the temperature rising region from the lower position of the shell 199. In this way, the air circulation is formed in the shell 199, and the hot air in the shell 199 is cooled by heat exchange.

[0081] In some embodiments, the air duct shell 199 connected with the condensing heat exchanger 106 and / or the condensing heat exchanger 106 has a second region. The second region is provided with a second light emitting body 173 and a light transmitting body corresponding to the second light emitting body 173. The light emitting body is fixed to the rear of the inner frame support through the clamping structure. One end of the light transmitting body is close to the second light emitting body 173, and the other end abuts against the bottom surface of the shell 199, so as to transmit the light emitted by the light emitting body to the bottom surface of the shell 199. Figures 16 to 18 As shown, the second PCB circuit board is arranged at the rear of the position of the shell 199 where the handle part 101 is located and above the condensing heat exchanger 106. The second PCB circuit board is provided with the second light emitting body 173. The fixing structure of the second PCB circuit board is similar to the fixing structure of the first PCB circuit board. The second light emitting body 173 is fixed through the clamping structure arranged in the first inner frame support 120 and the second inner frame support 130. The light transmitting body (not shown in the figure) is arranged at the position corresponding to the second light emitting body 173, so as to transmit the light emitted by the second light emitting body 173 to the bottom of the handle decoration part, and then display the light on the surface of the handle decoration part through the position of the transparent or semi-transparent handle decoration part, so as to realize the display. The second PCB circuit board is the display board 169. The indication of the second light emitting body 173 can correspond to other functions of the air conditioner, such as the operation state indication of the compressor 107, the indication of the charging state of the battery in the battery box 600 connected with the air conditioner, the battery power indicator and other functions.

[0082] In some embodiments, the first region and the second region are communicated. The upward air flow passes through the second light emitting body 173 and flows from the second region to the first region. The shell 199 forms an air flow channel. The air flow channel has an arc-shaped upward section and a downward section connected with the upward section. The highest point of the air flow channel is close to the first region. Figure 16As shown, the first region and the second region are located inside the shell 199 near the front and rear positions where the handle portion 101 is located. The surface of the inner frame support where the handle portion 101 is located forms an arc surface. The arc surface is lowered towards the rear portion at the position of the handle portion 101, and is raised towards the front portion at the position of the handle portion 101 to reach the highest position of the arc surface and then descend towards the evaporation air inlet 103. In this way, the second region above the condensation heat exchanger 106 is raised towards the first region above the evaporation heat exchanger 109, thereby adapting to the physical property of the rising of the hot air in the second region, i.e. the hot air in the second region slowly rises from the rear to the front along the inner wall of the inner frame support, i.e. the rising section of the arc surface, and reaches the position of the first region. The air temperature in the first region is slightly lower than that in the second region because the first region is close to the evaporation heat exchanger 109. In this way, preliminary heat exchange and cooling are performed. Then, the air in the first region descends along the descending section towards the front portion to the cooling region where the evaporation heat exchanger 109 is located. Because the hot air is cooled, the physical property of the hot air is to descend. In this way, the descending section is arranged to adapt to the physical property of the cooled air in the first region, thereby adapting the physical property of the flow direction of the air in the first region and the second region to the positions of the rising section and the descending section, and better promoting the flow speed of the air, thereby promoting the cooling of the first PCB circuit board and the second PCB circuit board, and better maintaining the working reliability of the air conditioner.

[0083] In some embodiments, a hollow handle passage is formed on the shell. The second region is connected to the first region through the handle passage, so that the air in the second region enters the first region through the handle passage. The second light emitting body 173 is arranged in the handle passage and is displayed through the outer wall surface of the handle passage. The inner frame support includes a first inner frame support 120 and a second inner frame support 130 which are symmetrically arranged. The first inner frame support 120 and the second inner frame support 130 are provided with a connecting structure. The first inner frame support 120 and the second inner frame support 130 are respectively provided with a first handle portion 123 and a second handle portion 131 which are symmetrically arranged on the upper portions of the first inner frame support 120 and the second inner frame support 130. The first handle portion 123 and the second handle portion 131 are formed with a plug-in structure, so that the first handle portion 123 and the second handle portion 131 are connected through the plug-in structure to form the hollow handle passage. The handle passage is formed with an air flow passage. The second light emitting body 173 is arranged in the handle passage, which is beneficial to heat dissipation of the light emitting element and improves the reliability of the light emitting element.
