Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more particularly to a locking structure, a water tank, and an air conditioner. Background Technology

[0002] The water tank is a very important component in an air conditioning unit. On the one hand, the water tank inside the air conditioning unit can collect the condensate produced in the air conditioning system. On the other hand, the water tank provides water to spray at the air inlet of the air conditioner. The sprayed water will carry away the heat at the air inlet, thereby improving the heat exchange rate of the air conditioner.

[0003] Most existing air conditioner internal water tanks use a pull-out structure. Pull-out water tanks are prone to relative misalignment and not being closed tightly. If the pull-out water tank is not closed tightly, it can easily be opened by external force when the air conditioner is running, causing the water tank to malfunction or even causing the water inside the tank to spill out. Summary of the Invention

[0004] This invention provides a locking structure, a water tank, and an air conditioner to solve the defect in the prior art where pull-out water tanks are easily opened by external force when the air conditioner is running, causing the water tank to malfunction.

[0007] According to a locking structure provided by the present invention, the guide plate includes a guide plane plate and two guide limiting plates perpendicularly connected to both ends of the guide plane plate. The inclined groove is disposed on the guide plane plate, and each of the two guide limiting plates is provided with a first guide groove. The driving assembly includes a drive shaft and a driving member connected to the drive shaft. The drive shaft passes through the two first guide grooves, and the driving member drives the drive shaft to move along the first direction, thereby moving the guide plate.

[0008] According to a locking structure provided by the present invention, the base includes a base planar plate and two base vertical plates vertically connected to both ends of the base planar plate. The two base vertical plates are parallel to the guide limiting plate. A parallelogram groove is provided on the base vertical plate. The drive shaft passes through the parallelogram groove and the first guide groove. The first guide groove is an L-shaped guide groove. The guide plate is connected to a first spring that extends and retracts along the first direction. The first spring is connected to the base.

[0009] According to a locking structure provided by the present invention, the driving member includes a driving plane plate and two driving vertical plates vertically connected to both ends of the driving plane plate; the driving plane plate is connected to a second spring that extends and retracts along a first direction, the second spring is connected to the base, the driving plane plate is provided with a protruding structural member, the protruding structural member is located on the moving path of the locking member; the driving vertical plates are slidably connected to the base, the driving vertical plates are provided with a second guide groove, the second guide groove is an L-shaped guide groove, and the driving shaft passes through the second guide groove.

[0010] According to a locking structure provided by the present invention, the locking structure further includes a locking limiting plate, which is slidably connected to the base and adapted to slide on the base along a second direction, the second direction being perpendicular to the first direction. The locking limiting plate is connected to a third spring that extends and retracts along the second direction, and the third spring is connected to the base. The locking limiting plate is provided with a locking limiting groove and an unlocking groove. A smooth protrusion is provided on the side wall of the locking limiting groove along the first direction to form an unlocking position and a locking position within the locking limiting groove. A second sliding member is inserted into the locking limiting groove and is connected to the guide plate. The protruding structural member of the driving member is inserted into the unlocking groove, and a ramp structure is formed within the unlocking groove.

[0012] The present invention also provides a water tank, including a water tank frame and a water tank body movably disposed within the water tank frame. The water tank frame and the water tank body are connected by any of the above-described locking structures to achieve locking or unlocking between the water tank frame and the water tank body.

[0013] According to a water tank provided by the present invention, the water tank frame and the water tank body form a drawer structure, the base of the locking structure is fixed to the inner end of the water tank frame, and the locking member of the locking structure is fixed to the inner end of the water tank body.

[0014] The present invention also provides an air conditioner comprising the above-mentioned water tank.

[0015] The locking structure, water tank, and air conditioner provided by this invention fix a base and a locking component to two objects that need to be locked. Locking and unlocking between the two objects are achieved through relative movement between the base and the locking component. Specifically, the locking component moves towards the base. When the locking component enters the base, the pawl rotates on the base via a drive mechanism, clamping and limiting the locking component, thus locking it onto the base. When unlocking is required, the pawl rotates in the opposite direction on the base via the drive mechanism, releasing the restriction on the locking component and allowing it to unlock and disengage from the base. This locking structure, applied to a pull-out water tank in an air conditioner, prevents the water tank from being accidentally opened by external force during air conditioner operation, ensuring the normal operation of the air conditioner water tank.

Detailed Implementation

Obviously, the described embodiments are only some, not all, of the embodiments of this invention.

Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0030] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0033] The following is combined with Figures 1 to 10 The specific structure and working process of the locking structure, water tank, and air conditioner of the present invention are described.

[0034] A specific embodiment of the present invention provides a locking structure, combined with Figure 1 and Figure 2 As shown, the device includes a base 1 and a locking element 2. The base 1 and the locking element 2 are respectively fixed to two objects that need to be locked. The locking element 2 can move along a first direction toward or away from the base 1. A pawl 3 is rotatably provided on the base 1. The pawl 3 is connected to a drive mechanism, which is suitable for driving the pawl 3 to rotate so that the pawl 3 can switch between a locked state and an unlocked state. In the locked state, the pawl 3 engages with the locking element 2 to restrict the pawl 3 to the base 1. In the unlocked state, the pawl 3 releases the restriction on the locking element 2 so that the pawl 3 can disengage from the base 1.

[0035] It is understood that in this locking structure of the embodiment, the base 1 and the locking element 2 are respectively fixed to the two objects to be locked. The locking and unlocking of the two objects is achieved through relative movement between the base 1 and the locking element 2. Specifically, see... Figure 1As shown, the locking member 2 moves towards the base 1. After the locking member 2 enters the base 1, the pawl 3 rotates on the base 1 via the drive mechanism, locking the locking member 2 in place and securing it to the base 1. This achieves a relative lock between the base 1 and the locking member 2. When unlocking is required, the pawl 3 rotates in the opposite direction on the base 1 via the drive mechanism, releasing the restriction on the locking member 2 and allowing it to unlock and disengage from the base 1. Applying this locking structure to the pull-out water tank of an air conditioner prevents the water tank from being accidentally opened by external force during operation, ensuring the normal operation of the air conditioner water tank.

[0036] See Figure 2 As shown, the jaws 3 can be configured as two opposing jaws. When the two jaws 3 rotate on the base 1, they can move closer or further apart relative to each other. See [reference needed]. Figure 5 As shown, the locking component 2 may include an upper connecting block and a lower locking block. The connecting block is used to connect with the object, and the locking block is arrow-shaped. When the locking component 2 moves to the middle of the two claws 3, the two claws 3 rotate relative to each other and move closer. The ends of the claws 3 clamp the arrow-shaped locking block, thereby locking the locking component 2 and the base 1. Similarly, when the two claws 3 rotate relative to each other and move away, the ends of the claws 3 leave the arrow-shaped locking block, thereby unlocking and disengaging the locking component 2 and the base 1.

[0037] In some embodiments of the locking structure of the present invention, combined with Figure 1 and 7 As shown, the driving mechanism includes a guide plate 4 and a driving assembly 5. The guide plate 4 is slidably disposed on the base 1. The driving assembly 5 is connected to the guide plate 4 to drive the guide plate 4 to move along a first direction. The guide plate 4 is provided with a groove 401. A first sliding member 402 passes through the groove 401. The first sliding member 402 is connected to a claw 3.

[0038] It is understood that the locking structure of this embodiment is described in [reference needed]. Figure 7 As shown, two symmetrical inclined grooves 401 are provided on the guide plate 4, and a first sliding member 402 is provided in the inclined groove 401. The first sliding member 402 is connected to the claw 3. As the drive assembly 5 drives the guide plate 4 to move... Figure 6 In the structure shown, the up-and-down movement (first direction) causes the first sliding member 402 to generate an arc-shaped movement trajectory due to the action of the inclined groove 401. The first sliding member 402 drives the claw 3 to rotate around the rotation axis, so that the two claws 3 are relatively close or far apart, so as to lock or unlock the locking member 2.

[0039] Specifically, in some examples, see further. Figure 7As shown, the guide plate 4 includes a guide plane plate 403 and two guide limiting plates 404 perpendicularly connected to both ends of the guide plane plate 403. An inclined groove 401 is disposed on the guide plane plate 403, and each of the two guide limiting plates 404 is provided with a first guide groove 405. The drive assembly 5 includes a drive shaft 501 and a drive member 502 connected to the drive shaft 501. The drive shaft 501 passes through the two first guide grooves 405, and the drive member 502 drives the drive shaft 501 to move along a first direction, thereby moving the guide plate 4. It can be understood that the drive member 502 drives the drive shaft 501 in... Figure 6 In the structure shown, the up-and-down movement (first direction) is driven by the drive shaft 501 passing through the first guide groove 405 of the guide limiting plate 404, which in turn drives the guide plate 4 to move up and down. The up-and-down movement of the guide plate 4 ultimately achieves the relative approach or distance of the ends of the two claws 3, thereby locking or unlocking the locking member 2.

[0040] In other embodiments of the locking structure of the present invention, see Figure 6 As shown, the base 1 includes a base planar plate 101 and two base vertical plates 102 vertically connected to both ends of the base planar plate 101. The two base vertical plates 102 are parallel to the guide limiting plate 404. A parallelogram-shaped groove 103 is provided on the base vertical plate 102. The drive shaft 501 passes through the parallelogram-shaped groove 103 and a first guide groove 405, which is an L-shaped guide groove. A first spring 6, which extends and retracts along a first direction, is connected to the guide plate 4. The first spring 6 is connected to the base 1. Figure 4 and Figure 8 As shown, the driving component 502 includes a driving plane plate 5021 and two driving vertical plates 5022 vertically connected to both ends of the driving plane plate 5021; the driving plane plate 5021 is connected to a second spring 7 that extends and retracts along a first direction, the second spring 7 is connected to the base 1, the driving plane plate 5021 is provided with a protruding structural member 5023, the protruding structural member 5023 is located on the moving path of the locking member 2; the driving vertical plates 5022 are slidably connected to the base 1, the driving vertical plates 5022 are provided with a second guide groove 5024, the second guide groove 5024 is an L-shaped guide groove, and the driving shaft 501 passes through the second guide groove 5024.

[0041] Combination Figure 3 and Figure 6 As shown, it can be understood that the guide plate 4 is connected to the base 1 through the first spring 6, and the driving component 502 is connected to the base 1 through the second spring 7. During the downward movement of the guide plate 4 and the driving component 502, both the first spring 6 and the second spring 7 will be stretched. When the guide plate 4 and the driving component 502 are no longer under force and restricted, they will automatically retract and rebound due to the springs.

[0042] In this embodiment, the locking member 2 moves toward the base 1 and acts on the protruding structural member 5023 of the driving member 502. Since the driving vertical plate 5022 of the driving member 502 is slidably connected to the base 1, the driving member 502 will move downward with the locking member 2. The driving shaft 501 passes through the second guide groove 5024 on the driving vertical plate 5022. During the descent of the driving member 502, the driving shaft 501 passes through the transverse slot of the second guide groove 5024 and the transverse slot of the first guide groove 405. As the driving member 502 descends, it will drive the driving shaft 501 to descend. The driving shaft 501 drives the guide plate 4 to descend. During the descent of the guide plate 4, the two claws 3 rotate and move closer to each other, limiting the upper end of the arrow-shaped locking block of the locking member 2. At this time, the locking member 2 and the base 1 are locked and cannot be opened.

[0043] Continue moving the locking member 2 downwards. When the drive shaft 501 descends to the inclined surface of the parallelogram groove 103 corresponding to both sides of the base 1, the drive shaft 501 will move outwards perpendicular to the first direction under the influence of the inclined surface of the parallelogram groove 103. At this time, the drive shaft 501 will move from the transverse slot of the second guide groove 5024 and the transverse slot of the first guide groove 405 to the longitudinal slot of the second guide groove 5024 and the longitudinal slot of the first guide groove 405. When the drive shaft 501 is in the longitudinal slot of the second guide groove 5024 and the longitudinal slot of the first guide groove 405, the guide plate 4 and the drive member 502 are no longer subjected to the vertical downward squeezing force, and will move upwards under the rebound action of the first spring 6 and the second spring 7. During the upward movement of the guide plate 4, the two claws 3 rotate away from each other, and lose the limiting effect on the upper end of the arrow-shaped locking block of the locking member 2. At this time, the locking member 2 and the base 1 are unlocked and can be opened and disengaged.

[0044] As can be seen from the above process, the locking structure of the above embodiment forms the locking and unlocking between the locking member 2 and the base 1 at two positions where the locking member 2 moves toward the base 1. In this process, the drive shaft 501 plays a very important role in the transmission of power and the conversion of the locking state. The power transmission and the conversion of the locking state are mainly achieved by the shape structure of the first guide groove 405, the second guide groove 5024 and the parallelogram groove 103.

[0045] In other embodiments of the locking structure of the present invention, see again Figure 2 As shown, the locking structure also includes Figure 9The locking limiting plate 8 shown is slidably connected to the base 1 and is adapted to slide on the base 1 along a second direction, which is perpendicular to the first direction. The locking limiting plate 8 is connected to a third spring 9 that extends and retracts along the second direction, and the third spring 9 is connected to the base 1. The locking limiting plate 8 is provided with a locking limiting groove 801 and an unlocking groove 802. A smooth protrusion 803 is provided on the side wall along the first direction in the locking limiting groove 801 to form an unlocking position 804 and a locking position 805 in the locking limiting groove 801. A second sliding member 806 is inserted in the locking limiting groove 801 and is connected to the guide plate 4. The protruding structural member 5023 of the driving member 502 is inserted in the unlocking groove 802, and a ramp structure is formed in the unlocking groove 802.

[0046] It is understood that the locking limiting plate 8 in this embodiment plays a further limiting role during the locking state transition. During the locking process of the locking member 2 and the base 1, as the locking member 2 moves downward, it eventually drives the guide plate 4 to move downward. When the guide plate 4 moves downward, it drives the second sliding member 806 to move downward. In the initial state, the second sliding member 806 is located at the upper locking position 805 in the locking limiting groove 801. As the second sliding member 806 moves downward, it reaches the smooth protrusion 803, pushing the locking limiting plate 8 to move horizontally, and the third spring 9 is stretched. After the second slider 806 passes the smooth protrusion 803, the third spring 9 rebounds and pulls the locking limit plate 8 to reset. The second slider 806 reaches the locking position 805 at the lower part of the locking limit groove 801. At this time, the locking member 2 and the base 1 are in a locked state. Due to the obstruction of the smooth protrusion 803, even if the guide plate 4 is subjected to the rebound of the first spring 6, it is not easy to drive the second slider 806 to rise. That is, the smooth protrusion 803 prevents the second slider 806 and the guide plate 4 from rising to a certain extent.

[0047] As the locking member 2 continues to move downward, it pushes the extension structure 5023 of the driving member 502 to continue moving downward. The extension structure 5023 passes through the unlocking groove 802. As the extension structure 5023 continues to move downward, it will act on the ramp structure in the unlocking groove 802, pushing the locking limit plate 8 to move horizontally. As the locking limit plate 8 moves horizontally, the second sliding member 806 moves from the locking position 805 to the unlocking position 804 again. The locking limit groove 801 no longer restricts the second sliding member 806. The second sliding member 806 can rise together with the guide plate 4 under the rebound action of the first spring 6, so that the two claws 3 unlock the locking member 2, and the locking member 2 can be separated from the base 1.

[0048] Furthermore, based on the above embodiments, in some embodiments, the locking structure further includes an elastic piece 10, which contacts the drive shaft 501; the first guide groove 405 includes a sliding groove portion along a first direction and a limiting groove portion perpendicular to the sliding groove portion, and the elastic piece 10 is adapted to push the drive shaft 501 from the sliding groove portion of the first guide groove 405 to the limiting groove portion.

[0049] It is understood that the elastic plate 10 in this embodiment mainly restores the position of the drive shaft 501. When the drive shaft 501 passes through the transverse slot of the second guide groove 5024 and the transverse slot of the first guide groove 405, the elastic plate 10 is in a natural state. When the drive shaft 501 moves from the transverse slot of the second guide groove 5024 and the transverse slot of the first guide groove 405 to the longitudinal slot of the second guide groove 5024 and the longitudinal slot of the first guide groove 405, the elastic plate 10 is squeezed and deformed. When the guide plate 4 and the drive member 502 rise again, the elastic plate 10 needs to return to its natural state to push the drive shaft 501 from the longitudinal slot of the second guide groove 5024 and the longitudinal slot of the first guide groove 405 to the transverse slot of the second guide groove 5024 and the transverse slot of the first guide groove 405.

[0050] In another aspect, the present invention also provides a water tank, see [link to relevant documentation]. Figure 10 As shown, it includes a water tank frame 11 and a water tank body 12 movably disposed within the water tank frame 11. The water tank frame 11 and the water tank body 12 are connected by any of the above-mentioned locking structures to achieve locking or unlocking between the water tank frame 11 and the water tank body 12.

[0051] In some specific embodiments of the water tank provided by the present invention, see also Figure 10 As shown, the water tank frame 11 and the water tank body 12 form a drawer structure. The base 1 of the locking structure is fixed to the inner end of the water tank frame 11, and the locking member 2 of the locking structure is fixed to the inner end of the water tank body 12. After the water tank body 12 enters the interior of the water tank frame 11, the locking member 2 at its inner end moves toward the base 1 at the inner end of the water tank frame 11. After the locking member 2 enters the base 1, the water tank frame 11 and the water tank body 12 are locked. When it is necessary to open the water tank, the water tank body 12 is pushed toward the interior of the water tank frame 11 again, which unlocks the water tank frame 11 and the water tank body 12. For details, please refer to the locking and unlocking implementation process of the locking structure described above.

[0052] In another aspect, the present invention also provides an air conditioner including the aforementioned water tank. Since the air conditioner includes the aforementioned water tank, it is understood that the air conditioner provided in this embodiment, because it includes the aforementioned water tank structure, also possesses all the functions of the aforementioned water tank structure, making it less likely for the air conditioner's water tank to be accidentally opened by external force during operation, thus ensuring the normal operation of the air conditioner.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
