Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an indoor unit of an air conditioner and an air conditioner. Background Art

[0002] With the popularization of air conditioners, in areas with relatively high temperatures, the concentration of particles and corrosive gases contained in the air is relatively high. Therefore, air conditioners with higher cooling capacities are generally used in such areas. To ensure such a high cooling capacity, the evaporator of the air conditioner needs to be made longer and larger, and the corresponding bottom case needs to be larger and longer. However, as the length of the indoor unit increases, the torsional stress on the bottom case is also greater, and the stress is mainly concentrated at the front drainage position of the bottom case. Since there are more dust particles in the air in this area, they generally adhere to the evaporator and all accumulate at the front water receiving tray position after the evaporator self-cleaning. Over time, it will cause corrosion, cracking and leakage. However, since the bottom case is of an integral structure, it is usually impossible to replace it when cracking and leakage occur, and the whole machine needs to be removed, resulting in an increase in after-sales costs and a decrease in the user experience during actual use.

[0003] Due to the technical problems in the existing air conditioners that the whole machine needs to be removed when the water receiving tray cracks and leaks, resulting in difficult maintenance and high maintenance costs, the utility model researches and designs an indoor unit of an air conditioner and an air conditioner.

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way restrictive of the present utility model and its application or use. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0041] It should be noted that the terms used here are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

[0042] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0043] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description.

Without otherwise stating, the above words have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0046] AsFigures 1-7 As shown in the figure, the present utility model provides an air conditioner indoor unit, which includes:

[0047] A bottom case 1 and a water receiving tray 2, the bottom case 1 and the water receiving tray 2 are of a split structure, and the bottom case 1 and the water receiving tray 2 are connected as a whole.

[0048] The bottom case 1 and the water receiving tray 2 are snap-connected together through a snap component;

[0049] The snap component includes a first snap 3 provided on the bottom case 1, the first snap 3 is bent to form a first slot 4, the water receiving tray 2 includes a first plate 5, and one end of the first plate 5 is inserted into the first slot 4, so that a snap connection is formed between the water receiving tray 2 and the bottom case 1;

[0050] The first snap 3 includes a guiding portion 6 at its free end, the surface of the guiding portion 6 facing the first plate 5 of the water receiving tray 2 is a guiding inclined surface 7, and the guiding inclined surface 7 can guide the movement and insertion of the first plate 5 of the water receiving tray 2.

[0051] By setting the bottom case and the water receiving tray of the air conditioner indoor unit as a split structure and connecting the water receiving tray to the bottom case, the water receiving tray can be separately detached from the bottom case in case of faults such as cracks and leaks in the water receiving tray, facilitating its repair or replacement, as well as cleaning or cleaning, avoiding the problem of blockage of the water receiving tray, and solving the problems of difficult installation and disassembly and repair of the integrally formed water receiving tray and bottom case in the prior art, complex structure, more parts, difficult wiring, and high cost, and solving the problem that the position of the water receiving tray of the existing integrated water receiving tray is difficult to clean and is easily blocked; by snap-connecting the bottom case and the water receiving tray into a whole through a snap component, the effect of snap-connecting the split-structured bottom case and water receiving tray into an integrated structure is realized, ensuring more convenient disassembly and repair when the water receiving tray fails, further improving the repair efficiency and reducing the repair cost; through the first slot formed by bending the first snap on the bottom case, the first plate of the water receiving tray can be snap-connected, realizing the efficient assembly and disassembly between the water receiving tray and the bottom case, facilitating the repair and replacement of the water receiving tray, further improving the repair efficiency and reducing the repair cost; by the guiding portion and the guiding inclined surface, the assembly and disassembly of the water receiving tray can be facilitated, the disassembly and assembly efficiency can be further improved, and the repair cost can be reduced. Through the setting of the above dimensions, the snap-fastening degree can be improved, loosening can be prevented, and the assembly efficiency can also be improved.

[0052] With the popularization of air conditioners, the concentration of particles and corrosive gases in the air in areas with higher temperatures is relatively high. To ensure high cooling capacity, the evaporator of the air conditioner needs to be made longer and larger, and the corresponding bottom case needs to be larger and longer. However, as the length of the indoor unit increases, the torsional stress on the bottom case becomes greater, and the stress is mainly concentrated at the front drain position of the bottom case. Since there are more dust particles in the air in the Middle East region, they generally adhere to the evaporator and all accumulate at the front water receiving tray position after the evaporator self-cleaning. Over time, this will cause corrosion, cracking, and leakage. However, since the bottom case is of an integrated structure, it is usually impossible to replace it when cracks and leaks occur, and the whole machine needs to be disassembled, resulting in an increase in after-sales costs.

[0053] The functional structure of the embodiment of the present utility model includes: a split water receiving tray and bottom case structure, mainly including a bottom case, a water receiving tray, an evaporator combination component. The specific embodiments are as follows; as Figure 4 shown, the main part of the split water receiving tray splits the original air duct into two parts (i.e., the bottom case and the water receiving tray are designed as a split structure). Preferably, the split starts at a position about 6 - 7 mm in front of the fixing screw of the evaporator angle bracket. If it is too large, it will cause the rotation center of the water receiving tray to move forward during installation, resulting in interference with the position of the bottom case screw post during installation. If it is too small, the strength of the fixing screw will be weak. Preferably, its size must exceed the edge of the position where the cross-flow fan blade mates with the bottom case, reducing the damage to the air duct and making the transition smooth. After splitting, the gap between the water receiving tray and the inner side of the bottom case air duct is 0.15 - 0.2 mm. Looking from the top, the left and right sides of the water receiving tray and the inner part of the bottom case air duct overlap as Figure 4 shown. To prevent air leakage after splitting, a buckle assembly is provided on the outside of the split bottom case.

[0054] In some embodiments,

[0055] An angle C is formed between the guiding inclined surface 7 and the plate surface of the first plate 5, C = 35° - 65° (preferably 45° - 55°). In the projection plane of the vertical plane, the length of the guiding inclined surface 7 is E, E = 8 - 14 mm (preferably 10 - 12 mm). After the end of the first plate 5 is snapped into the first card slot 4, the minimum gap between the first plate 5 and the slot wall of the first card slot 4 is D, D = 0.1 - 0.6 mm (preferably 0.12 - 0.2 mm).

[0056] The overlapping structure on the left side of the water receiving tray and the bottom case is as Figure 2As shown, when installing, the water receiving tray slides in along the buckle shown in the figure. The included angle C of the buckle is between 35° and 65°. If it is too small, it will be difficult to snap in; if it is too large, it will be easy to become loose. The length E of the guide groove is 8 - 14 mm, and its top is designed with an inclined surface to facilitate guiding. The gap D between the two after installation is about 0.1 - 0.6 mm. The gap should not be too small, otherwise abnormal noise is likely to occur during heating. If it is too large, vibration and loosening are likely to occur when the cross-flow fan blade moves.

[0057] In some embodiments,

[0058] The positions of the water receiving tray 2 and the bottom shell 1 other than the buckle assembly are overlapped with each other (for the overlapping position 19, see Figure 4 ), and at the overlapping positions, the gap between the water receiving tray 2 and the bottom shell 1 is 0 - 0.6 mm (preferably 0.1 - 0.2 mm).

[0059] This is a further preferred structural form of the present utility model, that is, the positions of the water receiving tray and the bottom shell other than the buckle assembly form an overlap, which can achieve the effect of complete assembly between the water receiving tray and the bottom shell, and also improves the assembly and disassembly efficiency and reduces the maintenance cost.

[0060] In some embodiments,

[0061] A motor 8 is arranged on the side surface of the water receiving tray 2. The motor 8 is connected with a motor wire 9. A drain part 10 and a clip 11 are also arranged on the water receiving tray 2. The motor wire 9 is guided to the clip 11 and fixed there; a boss 12 is also arranged on the water receiving tray 2. The minimum distance between the boss 12 and the drain part 10 is greater than the minimum distance between the motor 8 and the drain part 10. The minimum distance between the boss 12 and the drain part 10 is greater than the minimum distance between the clip 11 and the drain part 10. The boss 12 limits and guides the motor wire 9 between the motor 8 and the clip 11, so that the motor wire 9 reaches the boss 12 first after passing through the motor 8 and then reaches the clip 11.

[0062] The present utility model also has a structure of arranging a boss on the side surface of the water receiving tray. The boss structure is farther away from the drain part than the motor and the clip. And the motor wire is first limited and guided by the boss after coming out of the motor, and then guided to the clip, which can effectively prevent the motor wire from being eroded by the water dripping from the drain part when directly guided from the motor to the clip, prevent condensation, and effectively improve the safety performance.

[0063] In some embodiments,

[0064] The boss 12 has at least two, and the at least two bosses 12 are arranged at intervals. The horizontal distance between two adjacent bosses 12 is the width F, and F is 0.1-1.0 mm (preferably 0.2-0.5 mm) smaller than the diameter of the motor wire. A guiding hole 13 is further provided on the water receiving tray 2 between the boss 12 and the clamping buckle 11, and the guiding hole 13 allows the motor wire 9 to pass through it.

[0065] This is a further preferred structural form of the present utility model. Through more than two bosses, the clamping and fixing effect on the motor wire can be further improved, further preventing the occurrence of condensation on the motor wire and improving the safety performance. The specific embodiments of the wire routing part of the present invention are as follows. Since the air guide plate used is a single air guide plate, only the motor on the right side cannot be driven, so a motor is added on the left side. As Figure 5 shown, for the drain nozzle (drainage part 10), to avoid condensation dripping due to the motor wire being too close to the drain nozzle, bosses 12 are added on the water receiving tray to isolate the motor wire 9 from the drain nozzle. The width F between the two bosses should be 0.1-1.0 mm smaller than the wire diameter of the motor wire, so that the motor wire can be firmly clamped between the bosses. The designed opening (guiding hole 13) on the water receiving tray facilitates the motor wire to be clamped inside the wire groove, which can further improve the assembly efficiency and further prevent condensation on the motor wire.

[0066] In some embodiments,

[0067] The minimum distance of the wire passing space of the clamping buckle 11 is 0.1-1.0 mm (preferably 0.3-0.5 mm) smaller than the diameter of the motor wire 9.

[0068] The clamping buckle of the present utility model is also preferably limited by a structure with more than two bosses. The formed wire passing space should be 0.1-1.0 mm smaller than the diameter of the wire. On the one hand, it plays a role in fixing the wire, and on the other hand, it restricts the wire hanging down from the left motor, so that it can be firmly clamped inside the forward buckle and closely attached to the outer wall of the water receiving tray.

[0069] In some embodiments,

[0070] On the front surface of the water receiving tray 2, a first forward buckle 14, a second forward buckle 15 and a reverse buckle 16 are provided. The first forward buckle 14, the second forward buckle 15 and the reverse buckle 16 can sequentially clamp the motor wire 9, so that the motor wire 9 led out through the clamping buckle 11 is sequentially guided by the first forward buckle 14, the second forward buckle 15 and the reverse buckle 16.

[0071] The utility model also has snap structures such as the first and second forward snaps and reverse snaps arranged on the front of the water receiving tray, which can further rationally design the motor wiring of the water receiving tray, and effectively solve the problem that the existing water receiving tray has too many air-sweeping blades and cannot be integrated due to space problems.

[0072] In some embodiments,

[0073] The first forward snap 14 includes a first arm 17 and a second arm 18 connected to each other. The first arm 17 is connected to the water receiving tray 2 and protrudes outward. One end of the second arm 18 is connected to the protruding end of the first arm 17, and the other end extends upward in the vertical direction. There is a spacing width G between the second arm 18 and the water receiving tray 2, and G is 0.1-1.0 mm (preferably 0.3-0.5 mm) smaller than the diameter of the motor wire 9. The extension length of the second arm 18 is the height H of the first forward snap 14, and H = 8-14 mm (preferably 10-12 mm); and the first forward snaps 14 are multiple, and the multiple first forward snaps 14 are arranged at intervals in the horizontal direction on the front of the water receiving tray 2.

[0074] This is the preferred structural form of the first forward snap of the utility model, that is, a snap structure with an upward opening is formed, which is convenient for the motor wire to be snapped into it from top to bottom. The wiring on the front of the water receiving tray of the utility model is as Figure 6 shown. The wiring preferably mainly includes 1 clip, 5 first forward snaps, 1 second forward snap and 1 reverse snap.

[0075] The detailed view of the forward snap of the utility model is as Figure 6 shown. The thickness of the snap is mainly affected by the movement trajectory and cannot exceed the movement trajectory. If it exceeds the movement trajectory, it will cause movement interference and the snap will be damaged during installation. The effective width G of the snap needs to be 0.1-1.0 mm smaller than the wire diameter to ensure that the motor wire can be easily snapped in and taken out. Its height H is about 8-14 mm to ensure that at least 2 wires can be snapped in and prevent interference with the screw column surface at the top due to being too high. Preferably, a large fillet is designed on the outer edge of the snap to avoid sliding in even if the movement deviates during installation and rotation.

[0076] In some embodiments,

[0077] The second forward snap 15 includes a third arm, a fourth arm and a fifth arm connected to each other. The third arm is connected to the water receiving tray and protrudes outward. One end of the fourth arm is connected to the protruding end of the third arm, and the other end extends upward in the vertical direction. One end of the fifth arm is connected to the upper end of the fourth arm, and the other end extends toward the water receiving tray 2 and forms a space with the water receiving tray 2.

[0078] The reverse buckle includes a sixth arm and a seventh arm which are connected. The sixth arm is connected to the water receiving tray and protrudes outward. One end of the seventh arm is connected to the protruding end of the sixth arm, and the other end extends downward in the vertical direction.

[0079] This is the preferred structural form of the second positive buckle and the reverse buckle of the present utility model. The second positive buckle adds a fifth arm on the basis of the structure of the first positive buckle, that is, it also extends in the direction of the water receiving tray, which can further play the role and effect of fastening the motor wire; the opening of the reverse buckle of the present utility model faces downward, which can enable the motor wire to be snapped into the reverse buckle from bottom to top to form a snap connection.

[0080] The buckle designed at the last screw post of the water receiving tray of the present utility model is a reverse buckle. Because at this position, 4 wires need to pass through in the extreme state and the space is narrow. If designed as a positive buckle, the wires will pop out and cannot be snapped in. Designed as a reverse one, the 4 wires can be lifted upward as a whole by the limiting post on the right side to prevent them from popping out downward.

[0081] The present utility model also provides an air conditioner, which includes the aforementioned air conditioner indoor unit.

[0082] The present utility model provides a split water receiving tray and an air conditioner having the same. By splitting the water receiving tray, reasonably designing the overlapping position and the rotation center of the water receiving tray and the bottom case, the problem that it is difficult to replace the water receiving tray due to cracking and leakage caused by the harsh operating conditions of the air conditioner is solved. By reasonably designing the wiring of the water receiving tray, the problem that the existing split water receiving tray has too many swing blades and cannot be integrated due to space problems is solved.

[0083] The following technical problems are solved:

[0084] 1. Solved the problem that the water receiving tray of air conditioners used by users in high-temperature regions is prone to cracking and leakage under harsh conditions, and it is difficult to replace after-sales.

[0085] 2. Solved the problems of difficult installation, complex structure, many parts, difficult wiring and high cost of the existing split water receiving tray.

[0086] 3. Solved the problem that the position of the water receiving tray of the existing integral water receiving tray is difficult to clean and is easy to be blocked.

[0087] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model. The above is only the preferred implementation manner of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and modifications can be made without departing from the technical principle of the present utility model, and these improvements and modifications should also be regarded as within the protection scope of the present utility model.
