SUMMARY

[0004] The problem solved by the present application is that since the distance between the evaporator left support and the heat exchange fins of the evaporator is small, and the disassembly and assembly of the evaporator left support is performed on the front surface of the base in the related art, that is, the evaporator left support is arranged on the same side as the side surface on which the evaporator is installed, and thus the evaporator fins are easily scratched during the disassembly of the evaporator left support, which leads to hand cutting and low disassembly and assembly efficiency.

[0007] In one example of the present application, the locking member is rotationally connected with the base to be switched between a first relative position and a second relative position; when the locking member is mounted to the base in the first relative position relative to the left bracket of the evaporator, the locking member restricts the left bracket of the evaporator from being disengaged from the first mounting position; and / or when the locking member is switched from the first relative position to the second relative position relative to the left bracket of the evaporator, the locking member restricts the left bracket of the evaporator from being moved in the first mounting position.

[0012] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: further ensure the stable state of the first clamping end portion in the mounting slot, and effectively limit the warping of the first clamping end portion.

[0016] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: on the one hand, effectively limit the warping of the first clamping end portion; on the other hand, by increasing the extrusion force of the second clamping portion extruded to the stop portion, effectively limit the movement of the first clamping end portion in the mounting slot.

[0024] In one example of the present application, the base is provided with at least one positioning slot corresponding to the position of the first mounting hole; the fitting part is provided with a positioning protrusion for cooperating with the positioning slot; wherein, when the locking member is in the second relative position, the positioning protrusion enters the at least one positioning slot; and / or, when the locking member is in the first relative position, the positioning protrusion is arranged out of position with the at least one positioning slot.

[0025] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: the cooperation of the positioning slot and the positioning protrusion ensures that the locking member can be stably maintained in the second relative position, avoiding the situation that the locking member is turned from the second relative position to the first relative position due to the shaking of the body during the operation of the air conditioner, and further causing the first clamping end to be raised or the first clamping end to move unstably in the installation clamping groove.

[0026] In one example of the present application, the adjusting part is provided with a first auxiliary dismounting slot on the side close to the fitting part; and / or, the base is provided with a second auxiliary dismounting protrusion on the side close to the adjusting part, and when the locking member is installed to the base, the fitting part is fixed with the second auxiliary dismounting protrusion to form a dismounting distance between the corresponding side surface of the base.

[0027] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: the operator can apply a stable pulling force to the locking member through the first auxiliary dismounting slot and / or the second auxiliary dismounting protrusion to smoothly dismount the locking member from the base, thereby reducing the difficulty of taking the locking member off the base.

[0028] In one example of the present application, the adjusting part is provided with a positioning indication member at the end away from the fitting part; the base is provided with a plurality of positioning points on the wall-hanging side, and the plurality of positioning points are arranged circumferentially around the position of the first mounting hole.

[0032] After adopting the technical scheme of the present application, the following technical effects can be achieved:

[0033] (1) On the one hand, by installing the locking member from the hanging plate mounting position to the first mounting position of the base, the situation that the evaporator fins are scratched to cause hand cutting during the operation of installing the evaporator left support to the base is effectively avoided. On the contrary, during the process of disassembling the evaporator left support from the base, since the operator disassembles the locking member on the side of the bottom plate away from the first mounting position, the situation that the operator's hand contacts the evaporator fins is also effectively avoided, thereby improving the safety of the overall disassembly and assembly of the evaporator left support. On the other hand, the disassembly and assembly operation is adjusted to the back of the base. The back of the base can be understood as the side of the base where the hanging plate mounting position is located.

[0035] (3) The cross structure or T-shaped structure plays the role of installation prevention. In addition, since the cooperation part is an annular elastic rib, the force received due to the shaking of the machine body during the operation of the air conditioner can be reduced, the effect of moderately dispersing the structural stress is achieved, and the cracking of the locking member is avoided or alleviated.

DETAILED DESCRIPTION

[0052] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings.

[0053] Referring to Figure 1Fig. 1 is a structural schematic diagram of a base assembly 100 of an air conditioner according to an embodiment of the present application. Fig. 2 is a structural schematic diagram of the base assembly 100 of the air conditioner according to the embodiment of the present application. Figures 2-13 The base assembly 100 includes, for example, a base 10, an evaporator left support 20, and a locking member 30. The base 10 is provided with a hanging plate mounting position on one side, and a first mounting position is correspondingly provided on the side of the base 10 opposite to the hanging plate mounting position. The corresponding end of the evaporator left support 20 is matched with the first mounting position. The locking member 30 is mounted to the base 10 from the direction in which the hanging plate mounting position points to the first mounting position, so as to limit the evaporator left support 20 to the first mounting position.

[0054] For example, the air conditioner is a wall-mounted air conditioner, and the base 10 includes, for example, a wall-hanging side 101 and a mounting side 102. The wall-hanging side 101 can also be understood as the back side of the base 10, and the mounting side 102 is the front side of the base. The hanging plate mounting position is provided on the wall-hanging side 101, and the hanging plate is mounted to the hanging plate mounting position, so that the base 10 can be mounted to the wall. In contrast, the mounting side 102 is provided opposite to the wall-hanging side 101, and is used to mount various assembly parts of the indoor unit, such as the evaporator, cross-flow fan, etc. The first mounting position is also provided on the mounting side 102. For ease of understanding, the direction in which the hanging plate mounting position points to the first mounting position or the first mounting position points to the hanging plate mounting position can be defined as the longitudinal direction 103, and the left-right direction of the base 10 along the transverse length thereof is defined as the left-right direction.

[0055] Further, in combination with the actual installation scene of the wall-mounted air conditioner, the evaporator is mounted to the base 10 in a transversely arranged direction, and is limited from being separated from the base 10 by the mounting limiting structure of the base assembly 100 matched with the base 10. Specifically, the mounting limiting structure includes the evaporator left support 20 and a sheet metal side plate. The evaporator left support 20 is mounted to the left end of the base 10, and the sheet metal side plate is provided at the right end opposite to the left end.

[0056] Further, the evaporator left support 20 includes, for example, a first end arranged in the vertical direction and a second end. The first end is mounted to the upper end 181 of the base 10, and the second end is connected to the position of the lower end 182 of the base 10. In addition, the base 10 is provided with a first arc-shaped groove at the left end, which is adapted to the outer surface of the corresponding end of the evaporator. Correspondingly, the evaporator left support 20 is also provided with a second arc-shaped groove matched with the first arc-shaped groove, so as to stably mount the end of the evaporator to the base 10 by matching the first arc-shaped groove and the second arc-shaped groove.

[0057] In the related art, in order to reduce the difficulty of disassembling the evaporator left support 20, the first end portion is often buckled and connected with the corresponding end portion clamping groove provided on the base 10. Specifically, the base 10 is provided with a containing groove for containing the first end portion, and an elastic buckle is provided at the opening corresponding to the containing groove. The first end portion is provided with a pressing plate, and in the process of pressing the first end portion to make it enter the containing groove, the elastic buckle is elastically deformed due to the extrusion of the pressing plate provided on its upper surface, so that when the elastic buckle is buckled to the upper position of the pressing plate under the action of continuous pressure, the first end portion smoothly enters the containing groove, and at this time the clamping connection between the first end portion and the base 10 is completed. In addition, the connection relationship between the second end portion and the base 10 is screw connection.

[0058] However, in combination with the actual assembly of the evaporator on the base 10, due to the small distance between the evaporator left support 20 and the heat exchange fins of the evaporator, it is easy to scratch the evaporator fins during disassembly of the evaporator left support 20, which can cause hand injury. In addition, the deformation force of the elastic buckle needs to be overcome during disassembly of the evaporator left support 20, which further leads to low disassembly efficiency.

[0059] Therefore, in combination with the technical solution, on the one hand, by installing the locking member 30 from the hanging plate mounting position to the first mounting position of the base 10, the situation of scratching the evaporator fins and causing hand injury during the operation of installing the evaporator left support 20 to the base 10 is effectively avoided. On the contrary, during the process of disassembling the evaporator left support 20 from the base 10, the operator disassembles the locking member 30 on the side of the bottom plate away from the first mounting position, which also effectively avoids the situation that the operator's hand contacts the evaporator fins, thereby improving the safety of disassembling the evaporator left support 20. On the other hand, the disassembly operation is adjusted to the back of the base 10. The back of the back can be understood as the side of the base 10 where the hanging plate mounting position is located. Compared with disassembling the locking member 30 on the front of the bottom plate, the back has a larger space for disassembly, which is convenient for the operator to operate and improves the disassembly efficiency.

[0060] Preferably, the locking member 30 is rotationally connected with the base 10 to switch between the first relative position and the second relative position; when the locking member 30 is installed to the base 10 in the first relative position relative to the evaporator left support 20, the locking member 30 limits the evaporator left support 20 from being detached from the first mounting position; and / or when the locking member 30 is switched from the first relative position to the second relative position relative to the evaporator left support 20, the locking member 30 limits the evaporator left support 20 to move on the first mounting position.

[0061] In one specific example, the locking member 30 is mounted on the base 10 in a manner of being translated in the first relative position to cooperate with the evaporator left support 20, on the one hand, the locking member 30 is fixed to the evaporator left support 20 in a manner of being translated relative to the base 10 or the evaporator left support 20, so that the overall assembly difficulty is smaller, thereby improving the assembly efficiency; on the other hand, in combination with the actual operation of the air conditioner, the first mounting position is, for example, the upper end 181 position in the vertical direction of the base assembly 100 hanging on the wall, by enabling the locking member 30 to be flexibly switched between the first relative position and the second relative position, the situation that the evaporator extrudes the evaporator left support 20 to drive the corresponding end to be lifted under the action of gravity is effectively avoided, thereby improving the stability of the cooperation between the evaporator left support 20 and the base 10, in addition, the low cooperation precision caused by the buckle and slot cooperation mode in the related art is also avoided, which is easy to cause the corresponding end of the evaporator left support 20 to move on the first mounting position and produce noise, thereby reducing the user's experience.

[0062] Preferably, the extrusion force of the locking member 30 on the corresponding end of the evaporator left support 20 to the base 10 is increased or decreased during the switching of the locking member 30 between the first relative position and the second relative position.

[0063] Specifically, by rotating the locking member 30 to extrude the evaporator left support 20 towards the base 10, the evaporator left support 20 is prevented from being lifted from the corresponding surface of the base 10, thereby improving the stability of the evaporator left support 20 mounted on the base 10, in combination with the actual operation of the indoor unit, the evaporator is stably mounted on the base 10 by the close cooperation between the evaporator left support 20 and the base 10, avoiding the noise caused by the collision between the evaporator left support 20 and the base 10 due to the movement of the evaporator during operation, and even causing the structure of the base 10 and the evaporator left support 20 to be damaged; in addition, compared with the traditional clamping mode, the difficulty of disassembling the evaporator left support 20 is further reduced, by rotating the locking member 30, the evaporator left support 20 can be disassembled from the first mounting position, avoiding the need to overcome the deformation force of the elastic buckle during the disassembly of the evaporator left support 20 in the clamped state, which is laborious, in addition, the operator is also easy to scratch the evaporator fins to cause the accident of cutting hands.

[0064] Referring to Figure 14, preferably, the first mounting position is a mounting slot 13, and the base 10 is provided with a first mounting hole 14 corresponding to the position of the mounting slot 13, which is in rotational cooperation with the locking piece 30; the corresponding end portion is a first clamping end portion 21 clamped with the mounting slot 13, and the projection of the first clamping end portion 21 in the longitudinal direction 103 falls within the area surrounded by the first mounting hole 14; wherein, when the locking piece 30 is installed in the first relative position to the base 10, the locking piece 30 is in contact with the top end surface 22 of the first clamping end portion 21; when the locking piece 30 is converted from the first relative position to the second relative position, the extrusion force increases.

[0065] Continuing to combine Figure 14 In one specific example, the locking piece 30 is provided with a clearance gap 323 for accommodating the first clamping end portion 21, and a stop end portion is formed corresponding to the position of the clearance gap 323, which is used to limit the first clamping end portion 21 from being pulled out of the mounting slot 13, that is, by rotating the locking piece 30 to make the stop end portion abut against the first clamping end portion 21 to prevent it from being pulled out of the mounting slot 13. Specifically, when the locking piece 30 is installed in the first relative position to the base 10, the first clamping end portion 21 is located in the clearance space formed by the clearance gap 323, and when the locking piece 30 is adjusted to rotate around the axis of the first mounting hole 14, the stop end portion applies an extrusion force to the top end surface 22 to make it enter the mounting slot 13, thus effectively limiting the first clamping end portion 21 from being pulled up in the mounting slot 13, ensuring stable installation of the evaporator left bracket 20.

[0066] For example, the locking piece 30 can be divided into a first connecting portion and a second connecting portion according to cooperation with different objects, and when the locking piece 30 is installed on the base 10, the first connecting portion cooperates with the first mounting hole 14, and the second connecting portion is connected to one end of the first connecting portion close to the evaporator left bracket 20, and is used to cooperate with the evaporator left bracket 20.

[0067] Specifically, the first connecting portion can be a cylindrical structure, and correspondingly, the first mounting hole 14 is a circular hole adapted to the cylindrical structure; and the second connecting portion can be a semi-cylindrical structure, or other circular arc structures with different distances from the central axis 34 of the locking piece 30, such as an elliptical structure, or a cross structure with a length ratio greater than 1 or less than 1 in the transverse and longitudinal directions. By making the locking piece 30 cooperate with the evaporator left bracket 20 in the first relative position, the part of the second connecting portion with a shorter distance from the central axis 34 abuts against the top end surface 22 or forms a smaller spacing therebetween, and when the locking piece 30 is rotated from the first relative position to the second relative position, due to the limiting effect of the cooperation between the first connecting portion and the first mounting hole 14, the part of the second connecting portion with a longer distance from the central axis 34 extrudes the top end surface 22, thereby playing a role in limiting the first clamping end portion 21 from being pulled up.
