Detailed Description

It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict in structure or function. The present invention will be described in detail below with reference to examples.

The utility model discloses a condenser assembly, as shown in fig. 2 to 9, including air exhaust fan 117, air inlet section 188 and air-out section 189, air inlet section 188 is provided with condensation heat exchanger 106, and air-out section 189 is provided with air exhaust fan 117, and air inlet section 188's the wind direction of airing exhaust is opposite with the air inlet wind direction of air-out section 189, and air inlet section 188 sets up in baffle 180's both sides with air-out section 189 interval, and condensation heat exchanger 106 is 15 to 45 settings with the contained angle of air inlet direction to form wedge-shaped air inlet chamber 181. As shown in fig. 3 and 5, the air inlet section 188 is provided with a condensation air inlet 105, the air outlet section 189 is provided with a condensation air outlet 104, the air inlet section 188 and the air outlet section 189 are isolated by the partition plate 180, the air inlet section 188 and the air outlet section 189 are communicated through an air flow channel entering the air exhaust fan 117, when the air exhaust fan 117 works, a negative pressure region is formed in the air exhaust fan 117 of the air outlet section 189, so that the air outside the negative pressure region is sucked into the air inlet section 188 from the condensation air inlet 105, enters the air outlet section 189 through the condensation heat exchanger 106 for heat exchange, and is discharged from the air outlet section 189 through the condensation air outlet 104 through a high-speed rotation path of the air exhaust fan 117. The air inlet section 188 and the air outlet section 189 are separated by the partition 180, so that the chamber of the air inlet section 188 and the chamber of the air outlet section 189 are arranged in parallel, and the condensation air inlet 105 and the condensation air outlet 104 are also arranged in parallel, which is beneficial to the compact structural arrangement of the whole air inlet section 188 and the whole air outlet section 189. As shown in fig. 5, the condensing heat exchanger 106 is disposed in the cavity of the air intake section 188 in an inclined manner, specifically, the condensing heat exchanger 106 is disposed in an inclined manner from a side of the condensing air inlet 105 close to the partition plate 180 to a side of the air intake section 188 far from the partition plate 180, an included angle Φ 1 shown in fig. 5 is formed between the surface of the condensing heat exchanger 106 and the air intake direction, so as to form a wedge-shaped air inlet cavity 181, compared with the arrangement mode that the condensing heat exchanger 106 is parallel or nearly parallel to the direction of the inlet air in the prior art, the contact area between the air flow entering from the condensing air inlet 105 and the condensing heat exchanger 106 is increased, so that the air inlet surface of the whole condensing heat exchanger 106 can be uniformly entered with air flow, and the air flow at the air outlet side of the condensing heat exchanger 106 is also uniform, so that the air flow entering the exhaust fan 117 is also relatively uniform and the air flow finally discharged from the condensation exhaust outlet 104 is uniform. Whereas in the prior art arrangement where the condensing heat exchanger 106 is parallel or nearly parallel to the direction of the incoming air, the air flow entering from the condensation air inlet 105 is distributed unevenly on the surface of the inlet air of the condensation heat exchanger 106, the closer to the surface of the condensation air inlet 105, such as the air1 part of the air flow in fig. 5, the less the air contact amount on the surface of the condensation heat exchanger 106, and the more distant the surface of the condensation air inlet 105 such as the air2 portion of the air flow in fig. 5 contacts the surface of the condensation heat exchanger 106, thereby causing uneven distribution of the gas flow through the condensing heat exchanger 106, affecting the heat exchange efficiency of the condensing heat exchanger 106 on the gas flow, therefore, the air flow finally discharged from the condensation air outlet 104 is not uniform, and the amount of the air flow in the air inlet cavity 181 far away from the condensation air inlet 105 is large, so that a swirling effect is easily formed along the inner wall surface of the cavity at this time to cause turbulence, and further, large air flow noise is formed. And therefore, the overall condensing heat exchanger 106 assembly operates with increased noise. Through reasonable arrangement of the included angle between the condensation heat exchanger 106 and the air inlet direction, the air flow can form a uniform air inlet surface on the condensation heat exchanger 106, and further the air flow passing through the condensation heat exchanger 106 is uniform. The angle φ 1 may further preferably be 20 to 35, as φ 1 in FIG. 5 is about 22.

In some embodiments of the utility model, be provided with flaring section 190 between the income wind gap of air inlet chamber 181 and air inlet section 188, as shown in fig. 5, it has one section bore from the flaring section 190 of air inlet wind direction convergent to enter into the air inlet chamber 181 at condensation heat exchanger 106 place to go into wind gap 105 at the condensation to thereby make the air current through this section after thereby the increase enter into the air pressure in air inlet chamber 181 by the compression, help promoting the speed of the air flow through condensation heat exchanger 106, and then strengthen condensation heat exchanger 106's heat exchange efficiency.

In some embodiments of the present invention, an inverted wedge-shaped static pressure chamber 182 is formed between the condensation heat exchanger 106 and the exhaust fan 117, the fin-shaped combing air of the condensation heat exchanger 106 enters the static pressure chamber 182 from the air inlet section 188, and the static pressure chamber 182 is connected to the blowing area of the exhaust fan 117 through the air outlet 183 on the partition 180. Referring to fig. 3 and 5, the static pressure chamber 182 is substantially the same as the air inlet chamber 181 in shape and is disposed opposite to the air inlet chamber. Through setting up the static pressure chamber 182 of the wedge that falls for the space in its wind channel increases after the air current exports from condensation heat exchanger 106, thereby make the velocity of flow at this place reduce, therefore promote static pressure, it is more smooth and easy to enter into exhaust fan 117 from static pressure chamber 182 through gas vent 183 with the air current, static pressure chamber 182 pressure is more even moreover, make the velocity of flow of air through condensation heat exchanger 106 even, can further promote its heat exchange efficiency, and reduce the noise of air current route condensation heat exchanger 106 and gas vent 183 simultaneously.

In some embodiments of the present invention, as shown in fig. 3 and 4, the air outlet 183 is a circular hole for air exhaust, a first gradually tapered air guiding ring 184 extends from the circular hole to the direction of the air exhaust fan 117, and the first air guiding ring 184 forms a cylindrical outlet. Specifically, the air outlet 183 is a circular hole, the circular hole is provided with a first air guiding ring 184 with a gradually reduced aperture size towards the direction of the exhaust fan 117, the first air guiding ring 184 has an arc-shaped first inner air guiding surface 184a, and the first air guiding surface 184a extends towards the axial direction of the exhaust fan 117, so that when an air flow passes through the circular hole in the static pressure cavity 182, the air flow is guided by the first inner air guiding surface 184a to form an air flow which is consistent with the axial direction of the exhaust fan 117, such as the air flow air3 in fig. 4, and noise generated when the air flow passes through the air outlet 183 can be further reduced.

In some embodiments of the present invention, as shown in fig. 3 and 4, the exhaust fan 117 correspondingly extends a tapered second wind guiding ring 185 toward the circular hole, the second wind guiding ring 185 is sleeved on the periphery of the first wind guiding ring 184, and forms an annular first gap with the first wind guiding ring 184, and a free end of the second wind guiding ring 185 forms a second gap with a corresponding position of the partition board 180, the first gap range is 1.0mm to 3.0mm, and the second gap range is 1.0mm to 3.0 mm. The exhaust fan 117 is also provided with a second wind guide ring 185 opposite to the first wind guide ring 184, the aperture of the second wind guide ring 185 is larger than that of the first wind guide ring 184, the second wind guide ring is sleeved on the periphery of the first wind guide ring 184, the first wind guide ring 184 and the second wind guide ring 185 have an overlapping area in the wind direction of the intake wind, namely, a first outer wind guide surface 184b formed by the outer surface of the first wind guide ring 184 and a second inner wind guide surface 185a formed by the inner surface of the second wind guide ring 185 exist, wherein the first outer wind guide surface 184b and the second inner wind guide surface 185a are both arc-shaped, and the direction of a wind guide channel formed between the first outer wind guide surface 184b and the second inner wind guide surface 185a is. Because the second wind guiding ring 185 is connected with the wind wheel of the exhaust fan 117, the second wind guiding ring 185 and the exhaust fan 117 rotate synchronously during operation, so a certain gap needs to be reserved between the circular hole and the wind wheel to avoid interference to influence the rotation of the wind wheel, during the high-speed rotation process of the exhaust fan 117, the formed high-speed airflow has wind pressure around the wind wheel of the exhaust fan 117, and a certain negative pressure exists inside the wind wheel, so that a part of the airflow is sucked into the wind wheel through the gap and then enters the wind wheel. If the air guide channel formed between the first air guide ring 184 and the second air guide ring 185 is not provided, but is a gap of a conventional design, the part of the air flow enters the interior of the wind wheel along the wall surface of the partition 180, the air flow direction of the part of the air flow is consistent with the surface of the partition 180, the air flow direction of the part of the air flow is approximately vertical to the air flow direction entering from the circular hole along the axial direction of the exhaust fan 117, and therefore the air flow direction and the air flow direction collide and interfere at the gap, so that a large abnormal sound such as a squeaking sound is formed, and the use of a user is interfered. In order to avoid the problem, the first air guiding ring 184 is arranged at the circular hole, and the second air guiding ring 185 is arranged at one end of the wind wheel of the exhaust fan 117, so as to form an air guiding channel consistent with the axial direction of the fan between the two air guiding rings, as shown in fig. 4, when a part of air flow is the air flow air4 in fig. 4, the air flow air changes the direction after entering the air guiding channel along the surface of the partition board 180, and the air flow air3 consistent with the axial direction of the exhaust fan 117 is formed, so that the two air flow air and the air guiding channel do not cause interference, thereby eliminating the abnormal sound caused by the interference, and improving the experience of users in use. Through experiments, the first gap and the second gap select an appropriate gap range value, so that the condition that the circular hole does not interfere with the wind wheel in long-term operation can be met, an appropriate wind guide channel is formed to avoid the formation of air flow noise, and the value can be preferably 1.5mm to 2.0mm, such as 1.7 mm.

In some embodiments of the present invention, the condenser assembly further comprises a housing forming a wind channel, the housing having a bottom surface with a flat portion, and the partition 180 is disposed in the middle of the housing to divide the cavity in the housing into an air inlet section 188 and an air outlet section 189.

The casing specifically includes a first casing 186 on the side of the clad condensing heat exchanger 106 shown in fig. 8, and a second casing 187 on the side of the clad exhaust fan 117 shown in fig. 9.

The exhaust fan 117 is a centrifugal fan having an air flow discharge area and an air flow turning area between the centrifugal fan and the inner wall surface of the casing, and the air flow turning area and the air flow discharge area have opposite components. As shown in fig. 7, when the centrifugal fan rotates at a high speed, the blades of the wind wheel of the centrifugal fan continuously discharge the airflow sucked from the circular hole along the axial direction of the fan to the area between the wind wheel and the condensation exhaust outlet 104 along the rotation direction of the wind wheel, wherein most of the airflow is conveyed to the outside of the condensation exhaust outlet 104 as airflow air5 in fig. 7, and therefore the area is an airflow exhaust area, because of the lack of the volute tongue structure, a small part of the airflow continues to be rotated to the area between the wind wheel and the inner wall surface of the second housing 187 along the wind wheel, as airflow air6 in fig. 7, which is an airflow rotation area, the airflow in the airflow rotation area and the airflow in the airflow exhaust area contain opposite components in the airflow flowing direction, so that a part of the airflow in the airflow rotation area can re-enter the wind wheel from the wind guide channel between the first wind guide ring 184 and the second wind guide ring 185, accordingly, turbulence caused by the fact that the airflow in the area impacts the inner wall surface of the second outer shell 187 along the air exhaust direction away from the condensation air exhaust port 104 is reduced, noise is caused, the interference airflow in the airflow turning area is absorbed through the air guide channel, and therefore noise of the airflow can be further reduced.

Wherein the symmetry line of the air outlet segment 189 is L1 in fig. 7, and specifically as shown in fig. 7 and 9, the air outlet segment 189 of the casing, that is, the second casing 187, includes two parts, which are semicircular in shape with an arc shape at the front end, and as shown in the sectional view of fig. 7, the position starting from a boundary line L2 passing through the axis C1 of the exhaust fan 117 and formed perpendicular to the symmetry line L1 is the rear end, and the rear end starts from the boundary line L2 to the condensation exhaust outlet 104, and the upper and lower wall surfaces thereof are gradually reduced to the size of the condensation exhaust outlet 104, the arc-shaped section at the front end is adapted to the shape of the exhaust fan 117, and the tapered section at the rear end causes the air flow in the air flow discharge region to be gradually compressed to increase the air flow velocity discharged from the condensation exhaust outlet 104 to be discharged further backward, because the condensation air inlet 105 and the condensation exhaust outlet 104 are arranged side by side at the rear end of the casing, and are close to help to reduce the higher velocity of the air flow discharged from the condensation exhaust, the air flow interference between the two is reduced, and the heat exchange capacity of the condensing heat exchanger 106 is improved. In order to provide a suitable structural dimension of the tapering section for a reasonable acceleration effect on the air flow, as shown in fig. 7, the height of the second housing 187 at the condensation exhaust opening 104 is H1, and the height at the boundary line L2, i.e., at the position corresponding to the axis of the exhaust fan 117, is H2, wherein the ratio of H1 to H2 ranges from 1/2 to 4/5, i.e., from 0.5 to 0.8, and preferably, the modified range value may further range from 0.55 to 0.75, such as from 0.61 in fig. 7.

The utility model discloses still provide a portable air conditioner, as shown in fig. 1 to fig. 10, including bottom plate 142 and the casing 199 of being connected with bottom plate 142, be provided with oblique ascending evaporation air outlet 102 and the evaporation air intake 103 that is close to with evaporation air outlet 102 in the front side of casing 199, be provided with foretell condenser assembly at the rear portion of casing 199, casing 199 and bottom plate 142 are rectangular shape setting, be provided with evaporation heat exchanger 109 from the front to the back, compressor 107 and condensation heat exchanger 106, evaporation heat exchanger 109, connect through the refrigerant pipe between compressor 107 and the condensation heat exchanger 106, form refrigerating system with this. As shown in fig. 1, fig. 3 and fig. 7, the wind wheels of the evaporation air inlet 103, the evaporation heat exchanger 109 and the air inlet fan 108 are arranged substantially vertically and in parallel, the evaporation air outlet 102 is inclined upward and located obliquely above the air inlet fan 108, so as to form a substantially V-shaped air path channel from the air inlet to the air outlet, so that the arrangement of the components is compact, the overall occupied space is small, and the inclined evaporation air outlet 102 can avoid interference between the air outlet and the air inlet, that is, the cooling air discharged from the evaporation air outlet 102 is prevented from being directly sucked into the evaporation air inlet 103 to cause reduction of the cooling effect on the surrounding environment. Through setting up the casing 199 with the air conditioner to rectangular shape, the mobile air conditioner of common vertical appearance on the market relatively, its air conditioner height greatly reduced and bottom area increase are favorable to placing steadily to reduce the risk of overturning to this conveniently carries. And the refrigeration cycle components including the evaporation heat exchanger 109 and the heating cycle components including the condensation heat exchanger 106 are respectively arranged at two sides of the compressor 107, so that the center of gravity of the whole air conditioner is uniformly distributed, and the air conditioner is more suitable for being conveniently carried. The air conditioner is provided with a handle 101 on the upper surface of the casing, so that the whole air conditioner can be stably lifted up and carried easily by holding the handle 101.

In some embodiments, as shown in fig. 10, a water-receiving tray 162 is further disposed on the bottom plate 142, the water-receiving tray 162 has a first water-receiving section 1621 disposed below the evaporation heat exchanger 109, the water-receiving tray 162 is disposed at a front-to-rear inclination, and the water-receiving tray 162 is located above the bottom plate 142 and spaced apart from the bottom plate 142. Wherein, the periphery of the water pan 162 is a vertical wall surface, so as to form a cavity for containing water, the water pan 162 is arranged, and the first water receiving section 1621 of the water pan 162 is arranged below the evaporation heat exchanger 109, thereby collecting the condensed water generated by the evaporation heat exchanger 109 when the air conditioner refrigerates, avoiding the condensed water from directly flowing onto the bottom plate 142, and a certain distance exists between the water pan 162 and the bottom plate 142, such as 0.5cm to 5cm, so that an air space exists between the water pan 162 and the bottom plate 142, thereby preventing the low temperature of the condensed water on the water pan 162 from being transferred onto the bottom plate 142, and preventing the temperature of the bottom plate 142 from being reduced to generate condensation phenomenon, even if the condensation is generated on the outer surface of the water pan 162, the water quantity of small water drops generated by the condensation is much less than that of the condensed water, even if the water drops onto the bottom plate 142, the very small water drops can be evaporated by the bottom plate 142 with relatively high temperature, without a substantial decrease in the temperature of the bottom plate 142. And the water pan 162 is arranged to incline from the front side of the evaporation heat exchanger 109 to the rear side of the condensation heat exchanger 106, so that condensed water dropping from the evaporation heat exchanger 109 can be quickly drained away by the water pan 162, and can not be accumulated at the position of the first water receiving section 1621 to cause an overflow phenomenon.

In some embodiments of the present invention, the water receiving tray 162 further includes a second water receiving section 1622, which is a narrow plate and disposed under the refrigerant pipeline, and the refrigerant pipeline is the refrigerant pipe connection section 164 shown in fig. 3 for connecting the air suction pipe of the compressor 107 to the evaporation heat exchanger 109. According to the working principle of the air conditioner, the high-temperature and high-pressure gaseous refrigerant in the refrigerant pipe from the exhaust port of the compressor 107 passes through the condensing heat exchanger 106 to discharge heat outwards to cool the refrigerant in the refrigerant pipeline, then becomes low-temperature and high-pressure liquid refrigerant, passes through the throttling and pressure reducing component such as the capillary tube 163 to be throttled and reduced in pressure to become low-temperature and high-pressure liquid refrigerant with low temperature, then enters the evaporating heat exchanger 109, absorbs heat to the surrounding environment through the evaporating heat exchanger 109 to reduce the temperature of the refrigerant, the temperature of the refrigerant rises, the temperature in the refrigerant pipe penetrating through the evaporating heat exchanger 109 is very low, the temperature of the fins of the evaporating heat exchanger 109 installed on the refrigerant pipe is also very low, therefore, condensed water is generated and drops to the first water receiving section 1621 of the water receiving tray 162 below the evaporating heat exchanger 109, and then becomes low-temperature gaseous refrigerant after coming out of the evaporating heat exchanger 109, finally enters the suction port of, and the process is circulated.
