[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] The following combination Figures 1-6 The evaporator mounting structure according to the embodiment of the present invention is described.

[0029] The evaporator mounting structure of the present embodiment includes a base 1 and a motor 2. The base 1 includes a base body 11 and a front support member 12. The front support member 12 is disposed at one end of the base body 11 in a first direction. The motor 2 is mounted on the base body 11. The motor 2 and the front support member 12 are located at the same end of the base body 11 in the first direction. The motor 2 and the front support member 12 are spaced apart in a second direction, which is perpendicular to the first direction. The motor 2 includes a cover 21. The cover 21, the front support member 12, and an end surface of the base body 11 in a third direction jointly support the base body 11 when the base 1 is erected in the third direction, which is perpendicular to the first and second directions.

[0030] According to the evaporator mounting structure of the embodiment of the present invention, a front support member 12 is formed by extending from one side of the base body 11 along the first direction, and the front support member 12 and the cover body 21 of the motor 2 mounted on the base body 11 are spaced apart in the second direction. At this time, the front support member 12, the cover body 21 and one end face of the base body 11 in the third direction can simultaneously abut against the work surface to achieve stable support for the base 1 erected along the third direction, thereby ensuring that the notch 113 on the base body 11 is exposed, thereby effectively improving the installation efficiency of the evaporator 3 on the base body 11.

[0031] Need to explain the place, such as Figure 1 and Figure 2 As shown, the first direction is the front-to-back direction of the installed air conditioner indoor unit, the second direction is the left-to-right direction of the installed air conditioner indoor unit, and the third direction is the up-down direction of the installed air conditioner indoor unit. The front support member 12 is disposed in front of the base 11. The front support member 12 and the cover 21 of the motor 2 are respectively adjacent to the left and right ends of the base 11.

[0032] In some embodiments, as Figure 1 and Figure 2 As shown, the end surface of the base body 11 in the third direction includes a first end surface 111 and a second end surface 112. The base body 11 is provided with a notch 113 on the first end surface 111 for the copper tube on the evaporator 3 to pass through. The cover body 21, the front support member 12 and the second end surface 112 jointly support the base body 11 when the base 1 is erected along the third direction.

[0033] At this time, the evaporator 3 can be moved from top to bottom to insert the copper tube on the evaporator 3 into the notch 113 from top to bottom to complete the tube insertion operation, and then the evaporator 3 is moved to the set position on the base 11, and then the evaporator 3 and the base 11 are connected by fasteners, thereby realizing the installation of the evaporator 3 on the base 11, and the installation efficiency of the evaporator 3 is high.

[0034] Specifically, the first end surface 111 is the lower end surface of the base 11, and the front support 12 and the cover 21 of the motor 2 are arranged on the upper end surface of the base 11. That is, when the evaporator 3 is installed, the base 11 is placed upside down on the work surface.

[0035] In some embodiments, as Figure 1 As shown, the front support member 12 has a third end surface 121 in the third direction, the cover body 21 has a fourth end surface 211 in the third direction, and the third end surface 121, the fourth end surface 211 and the second end surface 112 are coplanar.

[0036] That is, the base body 11 is in contact with the work surface through the second end face 112, the third end face 121 and the fourth end face 211 so as to be placed upside down on the work surface. At this time, the second end face 112, the third end face 121 and the fourth end face 211 have higher support stability for the base body 11. When the evaporator 3 is installed, the base body 11 is less likely to shake back and forth or left and right, and the installation efficiency of the evaporator 3 on the base body 11 is higher.

[0037] In some embodiments, the evaporator 3 includes a first bracket 31 , a heat exchange portion, and a second bracket 32 ​​sequentially connected along the second direction. The first bracket 31 is snap-fitted to the base 11 , and the first bracket 31 is connected to the base 11 via fasteners.

[0038] That is, during the installation of the evaporator 3, after the copper tube passes through the notch 113, the position of the evaporator 3 is adjusted so that the first bracket 31 engages with the base 11. This achieves pre-positioning of the first bracket 31 on the base 11, facilitating the fastening of the first bracket 31 to the base 11 via the fasteners. This effectively ensures that the second bracket 32 ​​remains relatively fixed to the base 11, further facilitating the connection of the second bracket 32 ​​to the base 11.

[0039] Specifically, the notch 113 is adjacent to the right end of the base body 11 , the first bracket 31 is adjacent to the left end of the base body 11 , the fastener is a threaded member, and the first bracket 31 is connected to the base body 11 by bolts.

[0040] In some embodiments, as Figure 5 As shown, the first end and the second end of the base body 11 along the first direction are respectively provided with a first supporting portion 13 and a clamping portion 15 , and at least part of the first bracket 31 is pressed between the first supporting portion 13 and the clamping portion 15 along the first direction.

[0041] By sandwiching at least a portion of the first bracket 31 between the first support portion 13 and the clamping portion 15 , the first bracket 31 and the base 11 are relatively fixed, and the first bracket 31 is conveniently screwed to the base 11 .

[0042] Specifically, when at least part of the first bracket 31 is inserted between the first support portion 13 and the clamping portion 15, the clamping portion 15 will be forced to bend in a direction away from the first support portion 13, thereby enabling the clamping portion 15 to apply a clamping force to the first bracket 31 toward the first support portion 13, thereby making the pre-positioning reliability of the first bracket 31 on the base body 11 higher.

[0043] In some embodiments, the first support portion 13 includes an angled first support surface 131 and a second support surface 132, the first bracket 31 abuts against each of the first support surface 131 and the second support surface 132, the first support surface 131 is parallel to the side surface of the first end of the heat exchange portion adjacent to the seat body 11 in the first direction, and a threaded hole 133 is provided on the second support surface 132, and the fastener passes through the mounting hole on the first bracket 31 and is threadedly engaged with the threaded hole 133.

[0044] The angled first support surface 131 and the second support surface 132 abut against the first bracket 31, and the second support surface 132 is parallel to the rear side surface of the heat exchange portion and abuts against the rear side surface of the first bracket 31, so that the first support portion 13 has higher reliability in limiting the first bracket 31 in the front-to-back direction and the up-down direction. At the same time, it is also more convenient to combine with the clamping portion 15 to achieve reliable positioning of the first bracket 31 on the base body 11, and by arranging the threaded hole 133 on the second support surface 132 of the first support portion 13, the efficiency of the fastener connecting the first bracket 31 and the base body 11 is higher.

[0045] Specifically, if Figure 5 As shown, the first supporting surface 131 is located above the second supporting surface 132, the second supporting surface 132 is parallel to the front-to-back direction, and the second supporting surface 132 abuts against the rear side surface of the first bracket 31. At the same time, the clamping portion 15 abuts against the front side surface of the first bracket 31. The clamping portion 15 and the second supporting surface 132 realize the positioning of the first bracket 31 in the front-to-back direction, and the first supporting surface 131 realizes the positioning of the first bracket 31 in the up-down direction.

[0046] In some embodiments, as Figure 6 As shown, the second bracket 32 ​​is engaged with the base 11 , and a second support portion 14 is further provided at a first end of the base 11 along the first direction. The second support portion 14 abuts against a side surface of the second bracket 32 ​​along the first direction.

[0047] That is, the second bracket 32 ​​is clamped with the left end of the base 11. At this time, the connection strength between the left end of the evaporator 3 and the base 11 is lower than the connection strength between the right end of the evaporator 3 and the base 11. By setting the second support portion 14 to abut against the rear side of the second bracket 32, the left end of the evaporator 3 can be supported in the front and rear directions, which can better prevent the evaporator 3 from shaking or deforming when subjected to external force, and the installation reliability of the evaporator 3 on the base 11 is high.

[0048] Specifically, while the rear side surface of the second bracket 32 ​​abuts against the second support portion 14, the upper end surface of the second bracket 32 ​​can also abut against the base body 11. Combined with the clamping connection between the second bracket 32 ​​and the base body 11, the installation reliability of the second bracket 32 ​​on the base body 11 is effectively guaranteed.

[0049] In some embodiments, as Figure 6 As shown, the second support portion 14 includes a third support surface 141 . The third support surface 141 is parallel to the side surface of the heat exchange portion adjacent to the first end of the base 11 in the first direction. The third support surface 141 abuts against the second bracket 32 ​​.

[0050] At this time, the second support portion 14 supports the evaporator 3 in the oblique front and upper direction through the third support surface 141, thereby providing better support for the evaporator 3, better offsetting external impacts, and increasing the reliability of fixing the evaporator 3 on the base 1.

[0051] Specifically, the second bracket 32 ​​includes a hem protruding from the rear side of the heat exchange unit, which abuts the third support surface 141. The hem design of the second bracket 32 ​​increases the distance between the second support unit 14 and the heat exchange unit, reducing heat transfer efficiency between the two, and making the second support unit 14 less susceptible to condensation due to low temperatures. Furthermore, the left-right projection of the second support unit 14 is triangular, which increases the structural stability of the second support unit 14 and makes it less likely to bend downward relative to the base 1.

[0052] In some embodiments, the motor 2 further includes a base 22 , which is engaged with the second bracket 32 ​​.

[0053] That is, the base 11 is clamped with the second bracket 32 ​​through the base 22 of the motor 2 , thereby simplifying the structure of the base 11 and effectively reducing the manufacturing cost of the base 11 .

[0054] Specifically, the motor 2 is used to drive the crossflow impeller to rotate. The base 22 of the motor 2 is provided with a connecting flange, which is clamped to the upper end of the second bracket 32 ​​.

[0055] In some embodiments, as Figure 6 As shown, the base 22 is provided with a protrusion 221 extending along the second direction, and the second bracket 32 ​​is provided with a locking hole 321 , and the protrusion 221 is locked in the locking hole 321 .

[0056] That is, the base 22 fixes the second bracket 32 ​​in the up and down directions through the protrusion 221 , ensuring that the second bracket 32 ​​is reliably suspended and fixed on the base body 11 .

[0057] Specifically, the outer surface of the protrusion 221 is preferably spherical or conical. When the evaporator 3 moves from front to back toward the base 1, the second bracket 32 ​​and the protrusion 221 can slide relative to each other. When the evaporator 3 is moved into place, the protrusion 221 is locked in the locking hole 321. In addition, there are two protrusions 221. The cooperation between the two protrusions 221 and the two locking holes 321 further ensures the installation reliability of the second bracket 32 ​​on the base 11.
