Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

The following describes a cabinet air conditioner according to an embodiment of the present invention with reference to the drawings.

As shown in fig. 1 and fig. 2, a cabinet air conditioner 1 according to an embodiment of the present invention includes: a housing 10 and an evaporator 20.

Specifically, the housing 10 has an air inlet 10a and an air outlet 10b, and the housing 10 has an air duct 110 with two ends respectively connected to the air inlet 10a and the air outlet 10 b. Air may enter the air duct 110 from the inlet 10a and then be discharged from the outlet 10 b.

The evaporator 20 includes a first evaporator 21 and a second evaporator 22, the first evaporator 21 is disposed in the air duct 110, the second evaporator 22 is stacked with the first evaporator 21, and the first evaporator 21 and the second evaporator 22 have a first non-overlapping area 211 in a horizontal extending direction. Wherein only the first evaporator 21 or only the second evaporator 22 is present in the first non-overlapping area 211.

The air enters the air duct 110 from the air inlet 10a to exchange heat with the evaporator 20, and then is discharged to the indoor from the air outlet 10b, the air entering the air duct 110 can exchange heat with the first evaporator 21 or the second evaporator 22 of the first non-overlapping area 211, and can also exchange heat with the overlapping area having the first evaporator 21 and the second evaporator 22 at the same time, because the first non-overlapping area 211 only has the first evaporator 21 or the second evaporator 22, the wind resistance is small, and the ultra-far air supply can be realized in the first non-overlapping area 211.

In addition, since only the first evaporator 21 or the second evaporator 22 exists in the first non-overlapping area 211, the heat exchange effect of the air flowing through the first non-overlapping area 211 is poor compared with the heat exchange effect of the air flowing through the overlapping area, and when the cabinet air conditioner is heating, the temperature of the air flowing out of the first non-overlapping area 211 is lower than that of the air flowing out of the overlapping area, so that part of the air flow discharged from the air outlet 10b is reduced, and the temperature difference between the upper layer and the lower layer in the room can be reduced.

According to the utility model discloses cabinet air conditioner, through first non-overlapping region 211 that first evaporimeter 21 and second evaporimeter 22 formed on horizontal extending direction, first non-overlapping region 211 air supply temperature is on the low side when heating to improve indoor layering difference in temperature from top to bottom. In addition, the first non-overlapping area 211 has a small air blowing resistance, and thus ultra-far air blowing can be achieved. In addition, the first non-overlapping area 211 can reduce the space occupied by the evaporator 20 in the horizontal extending direction, provide a way for mounting other components inside the cabinet air conditioner 1, and provide possibility for reducing the size of the cabinet air conditioner 1.

Further, the first non-overlapping area 211 extends in the vertical direction, so that the length of the first non-overlapping area 211 in the vertical direction can be increased, the temperature of the air flow passing through the first non-overlapping area 211 of the evaporator 20 is low during heating, and the change of the distribution of the wind field is facilitated, so that the layered temperature difference is improved, the heat exchange effect is improved, and the user experience is improved.

Further, as shown in fig. 3, both ends of the first non-overlapping area 211 extend to both vertical ends of the evaporator 20, so that the area of the first non-overlapping area 211 can be further enlarged, the area of the area with the lower temperature of the airflow can be increased, and the effect of improving the temperature difference of the stratification layer can be enhanced.

According to some embodiments of the present invention, the first non-overlapping area 211 is located at least one of two ends of the horizontal extension of the evaporator 20. Specifically, the first non-overlapping area 211 may be located at the left end of both ends in the horizontal extending direction, may be located at the right end of both ends in the horizontal extending direction, and may have the first non-overlapping area 211 at both left and right ends in the horizontal extending direction. For example, both ends of the first evaporator 21 in the horizontal extending direction exceed the second evaporator 22, the first evaporator 21 and the second evaporator 22 overlap in the overlapping region, the first non-overlapping region 211 includes only the first evaporator 21, and the first non-overlapping region 211 includes two first sub-non-overlapping regions respectively located at both ends of the first evaporator 21 in the horizontal extending direction. For another example, one end of the first evaporator 21 in the horizontal extending direction exceeds the second evaporator 22, the other end of the first evaporator 21 in the horizontal extending direction is flush with the second evaporator 22, and the first non-overlapping area 211 is located at one end of the first evaporator 21 in the horizontal extending direction exceeding the second evaporator 22.

According to some embodiments of the present invention, the first non-overlapping area 211 is spaced apart from both ends of the horizontal extension of the evaporator 20. For example, the second evaporator 22 includes two spaced-apart second sub-evaporators, of which the two ends are flush with both ends of the first evaporator 21, respectively, in the horizontal extending direction, and the first non-overlapping area 211 is located between the two second sub-evaporators. This increases the structural versatility of the evaporator 20, so that different wind field distributions can be achieved.

It should be noted that the distance between the first non-overlapping area 211 and the two ends of the evaporator 20 needs to be designed according to experiments.

Further, the first non-overlapping area 211 includes a plurality of first sub non-overlapping areas spaced apart in the horizontal extending direction. For example, both ends in the horizontal extending direction of the first evaporator 21 are flush with both ends in the horizontal extending direction of the second evaporator 22, respectively, and the second evaporator 22 includes a plurality of first sub-evaporators spaced apart in the horizontal extending direction, and the region between the adjacent two sub-evaporators is configured as a first sub-non-overlapping region. Therefore, the structural diversity of the evaporator 20 can be increased, different wind field distributions can be realized, and different requirements of users can be met.

It should be noted that the actual size of the first sub non-overlapping area can be determined experimentally for different evaporators 20 under different operating conditions.

According to some embodiments of the present invention, the length of the evaporator 20 in the horizontal extending direction is L, the total length of the first non-overlapping area 211 in the horizontal extending direction is L1, and: l1 is more than 0 and less than or equal to 2/3L. It is understood that the first non-overlapping area 211 may include one first sub non-overlapping area or a plurality of first sub non-overlapping areas, when the first non-overlapping area has only one first sub non-overlapping area, the total length of the first non-overlapping area 211 in the horizontal extending direction is the length of one first sub non-overlapping area, and when the first non-overlapping area 211 includes a plurality of first sub non-overlapping areas, the total length of the first non-overlapping area 211 in the horizontal extending direction is the sum of the lengths of the plurality of first sub non-overlapping areas. Therefore, the distribution of the wind field can be changed, the layering temperature difference is improved, the heat exchange effect is improved, and the user experience is further improved.

Further, the total length L1 of the first non-overlapping area 211 in the horizontal extending direction and the length L of the evaporator 20 in the horizontal extending direction meet the requirement that L1 is more than or equal to 30mm and less than or equal to 1/3L, and the proper L1 can ensure that the evaporator 20 has good heat exchange effect and improve the layering temperature difference.

Further, the total length L1 of the first non-overlapping area 211 in the horizontal extension direction satisfies: l1 is more than or equal to 30mm and less than or equal to 250 mm. Therefore, the distribution of the wind field can be further changed, the layering temperature difference is improved, the heat exchange effect is improved, and the user experience is further improved.

According to some embodiments of the present invention, as shown in fig. 4 and 5, the first evaporator 21 and the second evaporator 22 have a second non-overlapping area 213 in the vertical direction, wherein only the first evaporator 21 or only the second evaporator 22 is provided in the second non-overlapping area 213.

The air enters the air duct 110 from the air inlet 10a to exchange heat with the evaporator 20, and then is discharged to the indoor from the air outlet 10b, the air entering the air duct 110 can exchange heat with the first evaporator 21 or the second evaporator 22 in the second non-overlapping area 213, and can also exchange heat with the overlapping area having the first evaporator 21 and the second evaporator 22 at the same time, because the second non-overlapping area 213 only has the first evaporator 21 or the second evaporator 22, the wind resistance is small, and the ultra-far air supply can be realized in the second non-overlapping area 213.

In addition, since only the first evaporator 21 or the second evaporator 22 is present in the second non-overlapping area 213, the heat exchange effect of the air flowing through the second non-overlapping area 213 is inferior to that of the air flowing through the overlapping area, and the temperature of the air flowing out of the second non-overlapping area 213 is lower than that of the air flowing out of the overlapping area during heating of the cabinet air conditioner, so that a part of the air flow discharged from the outlet 10b is reduced, and the temperature difference between the upper and lower floors in the room can be reduced.

In addition, the provision of the second non-overlapping area 213 can reduce the space occupied by the evaporator 20 in the vertical direction.

Specifically, the number of the second non-overlapping areas 213 is one or more.

Further, the second non-overlapping area 213 extends along the horizontal extending direction, so that the length of the second non-overlapping area 213 in the horizontal direction can be increased, the temperature of the air flow passing through the second non-overlapping area 213 of the evaporator 20 is lower during heating, and the change of the distribution of the wind field is facilitated, thereby improving the layered temperature difference, improving the heat exchange effect, and further improving the user experience.

Further, both ends of the second non-overlapping area 213 extend to both ends of the horizontal extending direction of the overlapping area of the evaporator 20, respectively. This makes it possible to increase the area of the second non-overlapping region 213 and the area of the region where the temperature of the airflow is relatively low, while simplifying the design structure.

Further, the second non-overlapping area 213 is located at least one of both ends in the vertical direction of the evaporator 20. Specifically, when there is only one second non-overlapping area 213, the second non-overlapping area 213 may be located at the upper or lower end of both ends in the vertical direction of the evaporator 20; when there are a plurality of second non-overlapping areas 213, at least one of the second non-overlapping areas 213 is located at one of the two ends of the evaporator 20 in the vertical direction, or two of the second non-overlapping areas 213 are distributed at the two ends of the evaporator 20 in the vertical direction.

For example, the evaporator 20 may be configured such that both ends in the vertical direction of the first evaporator 21 exceed the second evaporator 22, and the second non-overlapping area 213 includes two second sub-non-overlapping areas respectively located at both ends in the vertical direction of the first evaporator 21. As another example, as shown in fig. 4 and 5, one end in the vertical direction of the first evaporator 21 exceeds the second evaporator 22, the other end in the vertical direction of the first evaporator 21 is flush with the second evaporator 22, and the second non-overlapping area 213 is located at the end of the first evaporator 21 exceeding the second evaporator 22.

Further, the second non-overlapping area 213 is spaced apart from both ends in the vertical direction of the evaporator 20. For example, the second evaporator 22 includes two spaced apart second sub-evaporators, the two second sub-evaporators in the vertical direction are respectively flush with both ends of the first evaporator 21, and the second non-overlapping area 213 is located between the two second sub-evaporators. This increases the structural versatility of the evaporator 20, so that different wind field distributions can be achieved.

Further, the second non-overlapping area 213 includes a plurality of second sub non-overlapping areas spaced apart in the vertical direction. For example, both ends in the vertical direction of the first evaporator 21 are flush with both ends in the vertical direction of the second evaporator 22, respectively, and the second evaporator 22 includes a plurality of second sub-evaporators spaced apart in the vertical direction, and the region between adjacent two second sub-evaporators is configured as a second sub-non-overlapping region. Therefore, the structural diversity of the evaporator 20 can be increased, different wind field distributions can be realized, and different requirements of users can be met.

Further, the length of the evaporator 20 in the vertical direction is H, the total length of the second non-overlapping area 213 in the vertical direction is H1, and: h1 is more than 0 and less than or equal to 2/3H, and proper H1 enables the evaporator 20 to have good heat exchange effect and can improve the layering temperature difference. It is understood that the second non-overlapping area 213 is configured to have only one second sub non-overlapping area or a plurality of second sub non-overlapping areas, when the second non-overlapping area 213 has only one second sub non-overlapping area, the total length of the second non-overlapping area 213 in the vertical extending direction is the length of the second sub non-overlapping area, and when the second non-overlapping area 213 includes a plurality of second sub non-overlapping areas, the total length of the second non-overlapping area 213 in the vertical extending direction is the sum of the lengths of the plurality of second sub non-overlapping areas. Therefore, the distribution of the wind field can be changed, the layering temperature difference is improved, the heat exchange effect is improved, and the user experience is further improved.

Further, the total length H1 of the second non-overlapping area 213 in the vertical direction satisfies: h1 is more than or equal to 50mm and less than or equal to 250 mm. Therefore, the distribution of the wind field can be further changed, the layering temperature difference is improved, the heat exchange effect is improved, and the user experience is further improved.

It is to be noted that, as shown in fig. 6 and 7, when the first non-overlapping area 211 extends in the vertical direction and the second non-overlapping area 213 extends in the horizontal extending direction of the evaporator 20, the first non-overlapping area 211 and the second non-overlapping area 213 may have an overlapping area.

According to the utility model discloses a some embodiments, in cabinet air conditioner 1, along the air current direction of flow, first evaporimeter 21 can set up in second evaporimeter 22's low reaches, perhaps first evaporimeter 21 sets up in second evaporimeter 22's upper reaches, all can realize above-mentioned beneficial effect, no longer gives unnecessary details here.
