The entire disclosure of which is incorporated by reference into the present disclosure.

This disclosure relates to the field of air conditioning technology, and in particular to an air conditioning indoor unit that can be disassembled and cleaned.

As living standards improve, people have increasingly higher requirements for their living environment, and air conditioners are widely used to adjust the comfort of rooms by controlling the environmental temperature and/or humidity.

After a certain period of use, a large amount of dust accumulates in the internal air duct system and other components of a conventional air conditioner, which makes it easy for harmful bacteria to grow, making the air conditioner a secondary pollution source and harmful to human health. Conventional air conditioners have a complicated assembly relationship between the various components, and users cannot disassemble and clean them themselves. Therefore, air conditioners that are easy to disassemble and clean are now becoming more widespread. When the indoor unit is operating, the fan continues to rotate, and air passes through the air duct member and exchanges heat with the evaporation member, and is then blown out from the blowing member. Dust and bacteria in the air are likely to accumulate in the air duct member, which, if left as is, will affect the quality of the blown air and further affect the health of the user. Therefore, in a conventional air conditioner that can be disassembled and cleaned, the air duct member is provided so as to be removable from the housing and base body of the indoor unit, which makes it easy to clean the air duct member. However, a conventional removable air duct member is generally connected to the base body and housing via several screws, so that when removing it, it is necessary to remove all the screws on the air duct member in order. In addition, when removing the unit, it is necessary to store the screws without confusing their dimensions and installation positions so that they can be reassembled. This causes great inconvenience during cleaning and creates a poor user experience. Furthermore, if the screws are assembled multiple times, the screw holes will be damaged, making the installation of the air passage components unstable.

An embodiment of the present disclosure provides an air conditioning indoor unit that can be disassembled and cleaned.

Air conditioning indoor units that can be disassembled and cleaned are:
A housing having a first opening;
A base provided within the housing;
an air passage member that is detachably connected to the base and is removable through the first opening, and has an air passage casing, the air passage casing having side walls provided on both left and right sides thereof, the side walls being provided with insertion holes, and lock grooves being provided at positions corresponding to the respective insertion holes on the base;
a locking portion having one end attached to the air passage casing and the other end movably connected to the base, which, when connected to the base, can prevent the air passage member from being removed through the first opening, and each of the side walls of the air passage casing is provided with one of the locking portions, the locking portion including a main body, a connecting shaft being provided at a first end of the main body and a toggle portion being provided at a second end of the main body, a latching portion being provided in the main body between the connecting shaft and the toggle portion, the locking portion being provided between the two side walls, and being inserted from the inside to the outside into the insertion hole via the connecting shaft.

For example, they may be fixedly connected, detachably connected, or integrally connected; mechanically connected, or electrically connected; directly connected, indirectly connected via an intermediate medium, or internally connected between two elements. Those skilled in the art may understand the specific meaning of the above terms in the present disclosure according to the specific circumstances.

Figure 1 is a structural schematic diagram of an air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure. Figure 2 is an exploded view of an air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure. As shown in Figures 1 and 2, the air conditioning indoor unit that can be disassembled and cleaned in the embodiments of the present disclosure includes a housing 1, a base 2, an air passage member 3, a fan 4, an evaporation member 5, and a blowing member 6, and the base 2, the air passage member 3, the fan 4, and the evaporation member 5 are all provided inside the housing 1.

Here, both sides of the base 2 and both inner walls of the housing 1 are fixedly connected to form one mounting body. The air passage member 3 is attached to the base 2, and the fan 4 is provided in the air passage member 3. The evaporation member 5 is connected to the base 2 and is covered in the space above the fan 4. A first opening 11 is provided at the bottom of the housing 1, and a blowing member 6 is provided in the first opening 11, and the blowing member 6 includes a lower panel 61 and an air guide section 62. The lower panel 61 covers the first opening 11, and the front end of the lower panel 61 is movably connected to the housing 1. The lower panel 61 is provided with an air outlet 611, and the air guide section 62 is provided in the air outlet 611 to guide air. As shown in FIG. 4, the air passage member 3 includes an air passage casing 31, and an air passage cavity 311 is provided in the air passage casing 31. The housing 1 is provided with an intake port (not shown), and the intake port communicates with the inlet of the air passage cavity 311. As a result, during the specific operation process of the air conditioning indoor unit, air enters the air passage cavity 311 from the air intake, undergoes heat exchange via the fan 4 and the evaporative member 5, and is blown out from the air outlet 611.

The air passage member 3 is removably connected to the base 2 and can be removed through the first opening 11, making it easy to remove and clean the air passage member 3. In addition, a fan drive mechanism 8 is attached to one side of the base 2, and the fan 4 is removably connected to the fan drive mechanism 8, making it easy to remove the fan 4 from the air passage member 3 and clean it. In addition, because the fan drive mechanism 8 is provided on the side of the base 2, it is possible to prevent the charged fan drive mechanism 8 from being removed together with the fan 4, effectively ensuring the safety of the removal and cleaning operations.

3 is a schematic diagram of a connection structure between an air passage member and a base in an air conditioning indoor unit that can be disassembled and washed according to some embodiments of the present disclosure. As shown in FIG. 3, the air passage member 3 and the base 2 are removably connected by a locking part 9, and one end of the locking part 9 is hingedly attached to the air passage casing 31, and the other end is movably connected to the base 2. When the locking part 9 is connected to the base 2, it restricts the air passage member 3 from being removed through the first opening 11, thereby ensuring the stability of the assembly between the air passage member 3 and the base 2. In addition, since the locking part 9 is movably connected to the base 2, when the locking part 9 is detached from the base 2, the air passage member 3 can be removed from the base 2 by unlocking it from the base 2, which makes cleaning easier. In this way, there is no need to fix and connect the air passage casing 31 to the base 2 with a connector such as a screw, and the removal operation is simple. Even if the removal is repeated many times, the stability of the connection can be maintained, and the risk of incorrect installation or omission of the connector can be effectively avoided.

Figure 4 is a schematic diagram of the connection structure between the locking portion and the base in an air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure. Figure 5 is a partial enlarged view of part A in Figure 4. Figure 6 is a schematic diagram of the structure of the locking portion of an air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure. Figure 7 is a partial enlarged view of part B in Figure 6. As shown in Figures 4 to 7, the air passage casing 31 has side walls 312 provided on both the left and right sides, and each side wall 312 is provided with one locking portion 9.

8 is a configuration diagram of an air passage member of an air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure, as viewed from the bottom. FIG. 9 is a partial enlarged view of part C of FIG. 8. FIG. 10 is a structural schematic diagram of a base of an air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure. FIG. 11 is a structural schematic diagram of a locking part of an air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure. FIG. 12 is a structural schematic diagram of the locking part of FIG. 11, as viewed from another viewpoint. As shown in FIG. 9, an insertion hole 3121 is provided in the side wall 312, and as shown in FIG. 5 and FIG. 7, a lock groove 21 is provided at a position corresponding to each insertion hole 3121 of the base 2. As shown in FIG. 11 and FIG. 12, the locking part 9 includes a main body 91, a connecting shaft 92 is provided at a first end 911 of the main body 91, and a toggle part 93 is provided at a second end 912 of the main body 91. In addition, a locking part 94 is provided between the connecting shaft 92 and the toggle part 93 in the main body 91. The locking portion 9 is provided between the two side walls 312 and is inserted from the inside to the outside into the insertion hole 3121 via the connecting shaft 92. When the toggle portion 93 is turned, the main body 91 can be rotated around the connecting shaft 92, which allows the locking portion 94 to be inserted into the locking groove 21 and lock the air passage member 3. In Figs. 3 to 5, the locking portion 9 is locked to the locking groove 21, and when the toggle portion 93 is turned in the opposite direction, the main body 91 can be rotated around the connecting shaft 92 until the locking portion 94 is released from the locking groove 21, thereby unlocking the air passage member 3. In Figs. 6 and 7, the locking portion 9 is released from the locking groove 21. The locking portion 9 is easy to operate, and the air passage member 3 and the base 2 can be quickly attached and detached.

As shown in Figures 5, 7, 11, and 12, the connecting shaft 92 is provided perpendicular to the main body 91, and the main body 91 is attached parallel to the inner wall surface of the side wall 312, so that the installation space of the locking part 9 is saved and the integrity of the air passage member 3 is ensured.

Furthermore, as shown in Figs. 11 and 12, in some embodiments of the present disclosure, a stopper protrusion 921 extends radially from the end of the connecting shaft 92 facing away from the main body 91. As shown in Figs. 8 and 9, a notch 3122 is provided on one side of the insertion hole 3121 to allow the stopper protrusion 921 to escape along the axial direction, and the notch 3122 communicates with the insertion hole 3121 in the radial direction of the insertion hole 3121. When the connecting shaft 92 is assembled into the insertion hole 3121, the stopper protrusion 921 abuts against the end of the insertion hole 3121.

16 is a schematic diagram of the structure of an air-conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure after the air passage member and the locking part are assembled. FIG. 17 is a partial enlarged view of part D in FIG. 16. As shown in FIGS. 16 and 17, when attaching the locking part 9, while aligning the connecting shaft 92 with the insertion hole 3121, align the stopper protrusion 921 with the notch 3122, pass the connecting shaft 92 from the inside to the outside of the insertion hole 3121, and after the stopper protrusion 921 has completely passed through the notch 3122, rotate the connecting shaft 92 so that the stopper protrusion 921 avoids the notch 3122 and abuts against the outer wall surface of the side wall 312 in the outer peripheral region of the insertion hole 3121. This provides a stopper effect and a position control effect for the connecting shaft 92, preventing the locking part 9 from falling off the insertion hole 3121.

As still shown in Figures 10, 11, and 12, in some embodiments of the present disclosure, one bend in the main body 91 defines and forms the locking portion 94, and the locking groove 21 is elongated and extends in the vertical direction, and the depth of the locking groove 21 gradually increases from top to bottom, facilitating locking and unlocking between the locking portion 94 and the locking groove 21.

11 and 12, in some embodiments of the present disclosure, the width of the main body 91 gradually increases from the first end 911 to the second end 912, and the entire main body 91 has a fan-shaped structure. On the one hand, the strength and rigidity requirements of the locking part 9 are met, and on the other hand, the volume and weight are reduced while improving the aesthetics. The locking part 94 and the toggle part 93 are respectively connected to opposite sides of the second end 912 of the main body 91. The toggle part 93 is in the form of a long plate, and is smoothly connected to the side of the main body 91. Illustratively, in order to reduce the weight of the handle, the width of the toggle part 93 is 1/4 to 1/3 of the width of the second end 912 of the main body 91.

The main body 91, connecting shaft 92 and toggle portion 93 are molded as a single unit to ensure strength while reducing production costs and assembly requirements.

When the locking portion 9 is rotated to a position where it can be unlocked, in order to facilitate removal of the air passage member 3 and to prevent the locking portion 9 from interfering with the removal operation, as shown in FIG. 11, a stopper portion 913 is protruded from the side of the main body 91. The stopper portion 913 is located between the engaging portion 94 and the toggle portion 93, and an engagement groove 3123 is provided on the inner wall surface of the side wall 312. As shown in FIGS. 8 and 9, when the locking portion 9 is rotated until the stopper portion 913 contacts the engagement groove 3123, the rotation of the locking portion 9 is restricted.

Furthermore, a locking structure 313 that locks to the base 2 is provided on the rear side of the air passage casing 31. The cooperation between the locking structure 313 and the locking portion 9 allows the air passage casing 31 to be fixed to the base 2, making it easy to attach and detach.

8 and 9, the locking structure 313 includes a plurality of first snaps 3131 provided on the rear bottom of the air passage casing 31, which are bent upward and extend. As shown in FIG. 10, a plurality of first engagement grooves 22 that engage with the first snaps 3131 are provided on the bottom of the base 2. When the air passage member 3 is pressed into the base 2 and assembled to the target position, the first snaps 3131 engage with the first engagement grooves 22 in the base 2 and are fixed in place. This limits the degree of freedom of the air passage member 3 in the up and down direction, and cooperates with the locking portion 9 to ensure the stability of the air passage member 3.

For example, as shown in FIG. 10, the connection portion 23 is formed so as to extend rearward along the underside of the base 2, and the first engagement groove 22 is provided at the connection point between the connection portion 23 and the base 2. In this embodiment, four first engagement grooves 22 are provided spaced apart in the left-right direction.

The locking structure 313 further includes second engagement grooves 3132 provided at both the left and right ends of the rear side of the air passage casing 31, and as shown in Figs. 8 and 9, the second engagement grooves 3132 are provided close to the front end of the air passage casing 31. As shown in Fig. 10, the base 2 is provided with second snaps 24 that engage with the second engagement grooves 3132 in a one-to-one correspondence. When the air passage casing 31 is pushed backward into the base 2, the moment the second snaps 24 engage with the second engagement grooves 3132, a "click" sound is generated to indicate that the target position has been reached. At the moment of engagement, a sense of failure is also generated, informing the user that the air passage casing 31 has been assembled to the target position. This makes it easier for the user to sense the assembly state.

13 is a bottom view of an air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure after the base and the air passage member are assembled. FIG. 14 is a cross-sectional view along A-A in FIG. 13. FIG. 15 is a partially enlarged view of the base of an air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure. As shown in FIGS. 13 to 15, a first guide block 25 is provided on each of the left and right sides of the base 2, and a second guide block 314 is provided at each position opposite to each first guide block 25 on both sides of the air passage casing 31. The first guide block 25 is provided with a first guide surface 251 extending in the vertical direction, and the second guide block 314 is provided with a second guide surface 3141 extending in the vertical direction. The second guide surface 3141 slides in accordance with the first guide surface 251. During the installation and removal process, the air passage member 3 can be guided by the sliding of the first guide surface 251 and the second guide surface 3141, eliminating the need to time-consumingly estimate the distance for positioning in the left and right direction in advance, and the installation position can be determined in one go, eliminating the need for repeated trial and error or adjustments, and improving the efficiency of installation and removal.

The base 2 includes a bottom plate 26 and side plates 27 connected to the left and right sides of the bottom plate 26 and extending forward. A support surface 261 is provided on the front side of the bottom plate 26 for sliding the air passage member 3 up and down to be assembled. As shown in Figures 10 and 15, the two first guide blocks 25 are provided on the inner wall surfaces of the two left and right side plates 27 of the base 2, respectively, and the rear side surface of the first guide block 25 is defined as the first guide surface 251. Specifically, as shown in Figures 16 and 17, the second guide block 314 is provided on the outer wall surfaces on both sides of the air passage casing 31, and the front side surface of the second guide block 314 is defined as the second guide surface 3141. During the installation process, the second guide block 314 is inserted upward between the first guide block 25 and the support surface 261, so that the second guide surface 3141 is attached to the rear side of the first guide surface 251 of the first guide block 25, and the rear side of the second guide block 314 comes into contact with the support surface 261, improving the accuracy of the guide.

Figure 18 is a schematic diagram of the structure of an air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure after the evaporation member and air passage member are assembled. As shown in Figure 18, an end plate 51 is provided at the left end of the evaporation member 5, and an outer plate 32 is provided at the left end of the air passage member 3, and the end plate 51 and the outer plate 32 are aligned vertically and in sealing contact. The end plate 51 can be used to further position the air passage member 3, improving the assembly accuracy and connection stability of the air passage member 3.

As shown in Figures 18 and 19, the end plate 51 is semicircular and has a first arc groove formed on the lower edge of the end plate 51. The outer plate 32 is semicircular and has a second arc groove formed on the upper edge of the outer plate 32. When the lower edge of the end plate 51 abuts against the upper edge of the outer plate 32 in a vertical alignment, the first arc groove and the second arc groove form a circular hole for mounting the bearing assembly 10. In other embodiments of the present disclosure, the end plate 51 and the outer plate 32 may adopt a rectangular or other shaped structure.

19 is a structural schematic diagram of an air conditioner indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure after the fan is assembled with an air passage member and a fan drive mechanism. FIG. 20 is a partial enlarged view of part E in FIG. 19. FIG. 21 is a structural schematic diagram of a support seat of an air conditioner indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure. As shown in FIGS. 19 to 21, a bush 41 is provided at one end of the fan 4, and a lock screw 42 is provided in the bush 41 along the radial direction. A bearing assembly 10 is provided on one side wall 312, and a support seat 20 is provided on the other side wall 312. The support seat 20 is provided with an axial hole 201 and an escape groove 202 that communicates with the side of the axial hole 201 and allows the lock screw 42 to escape, and the escape groove 202 communicates with the axial hole 201 in the radial direction of the axial hole 201. Fan drive mechanism 8 has a motor shaft 81, one end of fan 4 is connected to bearing assembly 10, and the other end of fan 4 passes through shaft hole 201 via bushing 41 and is then fitted onto the outside of motor shaft 81, and lock screw 42 locks bushing 41 and motor shaft. The central axes of shaft hole 201, bearing assembly 10 and motor shaft 81 overlap, thereby ensuring concentricity and stability in the installation of fan 4. When installing air passage member 3, fan 4 is first installed to air passage member 3. In the process of mounting the fan 4, first, one end of the fan 4 is mounted to the bearing assembly 10, then the lock screw 42 on the bush 41 is aligned with the clearance groove 202, the bush 41 is passed through the shaft hole 201 of the support seat 20, the position of the bush 41 is determined in advance by the support seat 20, and finally, the assembled fan 4 and the entire air passage member 3 are mounted to the base 2, and after the air passage member 3 is assembled in the target position, the bush 41 and the motor shaft 81 of the fan drive mechanism 8 also become coaxial, and the bush 41 and the motor shaft 81 of the fan 4 are easily aligned and mounted in one go, improving the efficiency of assembly. Also, when removing the fan 4 from the fan drive mechanism 8, the fan 4 is moved a certain distance axially away from the fan drive mechanism 8, and then the bush 41 passes through the shaft hole 201, and the lock screw 42 on the bush 41 passes through the clearance groove 202 at the same time. After the bush 41 detaches from the motor shaft 81, it remains supported by the support seat 20, which prevents the fan 4 from being damaged by detaching from the motor shaft 81 and losing support.

In this embodiment, the support seat 20 can be molded integrally with the air passage member 3 (not shown), which reduces the assembly work required to assemble the support seat 20 and the air passage member 3.

Similarly, the support seat 20 may be provided so as to be removably connected to the air passage member 3. For example, as shown in FIG. 19 to FIG. 21, a mounting groove 3124 is provided in the right side wall 312, and the support seat 20 is removably connected to the mounting groove 3124. The insertion protrusion 203 and the fixing block 204 are provided at intervals on the outer periphery of the support seat 20, and the fixing block 204 is provided with a fixing hole 2041. The mounting groove 3124 is provided with an insertion hole (not shown) into which the insertion protrusion 203 is inserted, and a mounting position corresponding to the fixing block 2044 is provided. In this way, the support seat 20 is positioned by inserting the insertion protrusion 203 into the insertion hole and the fixing block 204 abutting the mounting position, and is further fixedly connected to the fixing block 204 via the fixing hole 2041, thereby attaching the support seat 20 to one side wall 312 of the air passage member 3. For example, the mounting location is a mounting base provided on the side wall 312.

In some embodiments of the present disclosure, as shown in FIG. 16, a condensation water channel 3125 is provided at the upper end of the side wall 312, and a drain outlet 3125a is provided at the end of the condensation water channel 3125. Condensed water formed by the evaporation member 5 is collected in the condensation water channel 3125 and discharged through the drain outlet 3125a at the end of the condensation water channel 3125, thereby ensuring normal operation of the air conditioning indoor unit.

In some embodiments, as shown in Figs. 1 and 2, the air conditioning indoor unit further includes a blowing member 6 provided in the first opening 11 for opening and closing the first opening 11. The blowing member 6 includes a lower panel 61 and an air guide section 62, the front end of the upper panel is movably connected to the housing 1, the lower panel 61 is provided with an air outlet 611, and the air outlet 611 is provided with an air guide section 62. As shown in Fig. 16, the front lower end of the air duct casing 31 is provided with a plurality of engagement sections 33 that engage with the lower panel 61, and fastens the air duct casing 31, the lower panel 61, and the base 2 together to improve the stability of the air conditioning indoor unit.

FIG. 23 is a partial enlarged view of the F part in FIG. 22. As shown in FIGS. 22 and 23, the air guide drive mechanism 30 is provided on one side of the base 2, and the link 40 is connected to the power output end of the air guide drive mechanism 30, and the link 40 is removably connected to the air guide section 62. On the lower side of the air passage casing 31, an opening groove 34 for the link 40 to pass through is provided on the side closer to the air guide drive mechanism 30. The air guide drive mechanism 30 swings the air guide section 62 by the link 40 to change the blowing direction. In addition, the link 40 passes through the opening groove 34 and extends into the air passage cavity 311. When removing the air passage member 3, first release the connection between the link 40 and the air guide section 62. Then, the link 40 is rotated to one side of the air guide drive mechanism 30 through the opening groove 34 to give way to the removal position. This avoids interference with the link 40 when removing the blowing member 6, ensuring smooth removal of the air passage member 3. At the same time, the operation of rotating the link 40 avoids removing the link 40 from the air guide drive mechanism 30, simplifying the removal and assembly process.

Typically, the opening groove 34 is a rectangular groove or an arc groove, and it is sufficient if it allows the link 40 to be attached or detached.

In some embodiments, as shown in Figures 1 and 2, a second opening 12 is provided on the front side of the housing 1. A front panel 7 is provided on the second opening 12 for opening and closing the second opening 12. By opening the front panel 7, localized cleaning of the evaporation member 5 can be performed.

In the process of removing and installing the air conditioning indoor unit of the present disclosure, in the case of removal, when the components such as the blowing member 6 and the fan 4 are in a state where removal is complete or removable, the toggle portion 93 of the locking portion 9 is moved to rotate the locking portion 9 forward so as to disengage from the locking groove 21. Then, the air passage casing 31 is pulled downward through the first opening 11, and the air passage member 3 is removed. In the case of assembly, the air passage casing 31 is pushed backward into the base 2 through the first opening 11 until the second snap 24 on the base 2 engages with the second engagement groove 3132 of the air passage casing 31. At this time, the air passage casing 31 is assembled to the target position. After that, the locking portion 9 is rotated backward, and the engaging portion 94 is engaged with the locking groove 21 of the base 2 to lock it.

As described above, the embodiment of the present disclosure provides an air conditioning indoor unit that can be disassembled and cleaned. The air passage member 3 is attached to the base 2, so that the removal and cleaning of the air passage member 3 is easy. The fan 4 is provided in the air passage cavity and is removably connected to the fan drive mechanism 8 on the base 2, so that the fan 4 can be easily removed from the air passage member 3 and cleaned. In addition, since the fan drive mechanism 8 is provided on the side of the base 2, it is possible to prevent the charged fan drive mechanism 8 from being removed together with the fan 4, and to ensure the safety of the removal and cleaning processes. In addition, the air passage member 3 is locked to the base 2 by the locking portion 9, and one end of the locking portion 9 is hingedly attached to the air passage casing 31 and the other end is movably connected to the base 2. When the locking portion 9 is connected to the base 2, it is possible to restrict the air passage member 3 from being removed through the first opening 11, and the assembly stability of the air passage member 3 and the base 2 is ensured. In addition, because the locking portion 9 is movably connected to the base 2, when the locking portion 9 is detached from the base 2, the air passage member 3 can be removed from the base 2 by unlocking the air passage member 3 from the base 2, which makes cleaning easy. In this way, there is no need to fix the air passage casing 31 to the base 2 with connectors such as screws, the removal operation is simple, the connection stability can be maintained even if the removal is repeated many times, and the risk of incorrect or missing connector attachment can be effectively avoided.
