Description

Technical Field

[0001] This invention relates to air conditioning technology, and in particular to a casing for a vertical air conditioner indoor unit and the vertical air conditioner indoor unit itself. Background Technology

[0002] In air conditioner indoor units, a filter is usually installed at the air intake grille to filter the air entering the unit and ensure cleanliness inside the casing. For easy cleaning, the filter is typically detachably attached to the air intake grille or the casing. Currently, the filter opening and closing structure of floor-standing air conditioner indoor units is mostly either a snap-on type or a magnetic attachment type. Snap-on filter opening and closing structures are prone to problems such as loose or overly tight snaps due to changes in ambient temperature and injection molding processes, and disassembly is relatively difficult, resulting in a poor user experience. Magnetic filter opening and closing structures are expensive, leading to a higher cost for the air conditioner indoor unit. Summary of the Invention

[0024] The fork is configured to abut against the air inlet grille during the process of the filter body switching from the open state to the closed state, and to move under the abutment of the air inlet grille so that the head moves out of the slot, thereby releasing the transmission member.

When the locking component disengages from the locking hole, the accumulated elastic deformation restoring force is released to cause the shift fork to rotate, thereby causing the tail of the shift fork to gradually separate from the air intake grille and causing the head of the shift fork to engage with the slot.

[0029] Optionally, the resilient opening and closing mechanism further includes:

[0030] The base plate is fixedly connected to the filter body; wherein

[0045] According to a second aspect of the present invention, the present invention also provides a vertical air conditioner indoor unit, which includes the casing described in any of the above embodiments.

[0046] The vertical air conditioner indoor unit of this invention features a specially designed elastic opening and closing mechanism on the filter body of each filter assembly. This mechanism allows the filter body to lock with the air inlet grille, keeping it in a closed state, with a simple operation of closing the filter body. Conversely, it releases the filter body by easily opening it, allowing it to switch to the open state. This invention replaces traditional, difficult-to-operate snap-fit ​​structures and costly magnetic structures with an elastic opening and closing mechanism, allowing for simple locking and releasing of the filter body. Users only need to perform simplified opening and closing operations, reducing operational difficulty and lowering the cost of the unit casing.

[0047] Furthermore, the elastic opening and closing mechanism includes a first elastic component, which can accumulate elastic deformation restoring force during the switching process of the filter body from a closed to an open state. On the one hand, it can release the accumulated elastic deformation restoring force during the reverse switching process of the filter body from an open to a closed state, thereby prompting the filter body to return to and maintain a closed state, reducing the force required for the user to close the filter body and improving the user experience. On the other hand, during the state switching process of the filter body, the first elastic component can generate a certain buffering effect, so that no matter how much force the user applies, it will not damage the elastic opening and closing mechanism or the filter body, improving the flexibility of the opening and closing force of the filter assembly.

[0048] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0058] This invention first provides a casing for a vertical air conditioner indoor unit. Figure 1 This is a schematic structural diagram of the casing of a vertical air conditioner indoor unit according to an embodiment of the present invention. See also... Figure 1 The housing 1 of the vertical air conditioner indoor unit of the present invention generally includes a main housing 10, and an air inlet 11 for airflow is provided on the main housing 10.

[0059] Furthermore, the housing 1 may also include an air intake grille 20 and at least one filter assembly 30 (see Figure 4 The air intake grille 20 is located at the air intake 11.

[0060] Figure 2 and Figure 3 These are schematic structural diagrams of the air intake grille and filter assembly in different orientations according to an embodiment of the present invention. Figure 4 This is a schematic exploded view of the air intake grille and filter assembly according to an embodiment of the present invention. See also Figures 2 to 4 Each filter assembly 30 includes a filter body 31 and an elastic opening and closing mechanism 32 disposed on the filter body 31.

[0061] The filter body 31 has a closed state covering at least a portion of the air inlet grille 20 and an open state where the air inlet grille 20 is open. That is, in the closed state, the filter body 31 can filter the airflow passing through the air inlet grille 20, and in the open state, the filter body 31 cannot filter the airflow passing through the air inlet grille 20.

[0062] The flexible opening and closing mechanism 32 is configured to operably lock the filter body 31 to the air inlet grille 20 so that the filter body 31 remains in a closed state and / or release the lock between the filter body 31 and the air inlet grille 20 to release the filter body 31 so that the filter body 31 switches to an open state.

[0063] The housing 1 of the vertical air conditioner indoor unit of the present invention is specially designed with an elastic opening and closing mechanism 32 on the filter body 31 of each filter assembly 30. The elastic opening and closing mechanism 32 can lock the filter body 31 with the air inlet grille 20 under the simple operation of the user to close the filter body 31, thereby keeping the filter body 31 in a closed state. It can also release the locking action between the filter body 31 and the air inlet grille 20 under the simple operation of the user to open the filter body 31, thereby releasing the filter body 31 and switching the filter body 31 to the open state.

[0064] This invention replaces the traditional snap-fit ​​structure with its tight and difficult-to-operate fastening force and the costly magnetic attraction structure with an elastic opening and closing mechanism 32. It switches the state of the filter body 31 in a simple way of locking and releasing, and the user only needs to perform a simplified opening and closing operation, which reduces the user's operating difficulty and the cost of the casing 1.

[0065] Figure 5 yes Figure 3 A schematic enlarged view of part B in the middle. In some embodiments, the elastic opening and closing mechanism 32 includes a first elastic member 321, which is configured to accumulate elastic deformation restoring force during the process of the filter body 31 switching from a closed state to an open state, and to release the accumulated elastic deformation restoring force during the process of the filter body 31 switching from an open state to a closed state, so as to cause the filter body 31 to return to and remain in the closed state.

[0066] The first elastic component 321 can accumulate elastic deformation recovery force during the switching process of the filter body 31 from closed to open. On the one hand, it can release the accumulated elastic deformation recovery force during the reverse switching process of the filter body 31 from open to closed, thereby prompting the filter body 31 to return to and maintain the closed state, reducing the force required for the user to close the filter body 31 and improving the user experience. On the other hand, during the state switching process of the filter body 31, the first elastic component 321 can generate a certain buffering effect, so that no matter how much force the user applies, it will not damage the elastic opening and closing mechanism 32, the filter body 31 and the air inlet grille 20, improving the flexibility of the opening and closing force of the filter assembly 30.

[0067] Figure 6 yes Figure 2 The schematic enlarged view of the middle part A shows that, in some embodiments, the air intake grille 20 has a locking hole 21 for cooperating with the elastic opening and closing mechanism 32.

[0068] Furthermore, the flexible opening and closing mechanism 32 also includes a locking member 322, which is configured to be operably movable relative to the air inlet grille 20 to selectively engage with or disengage from the locking hole 21. Specifically, when the locking member 322 engages with the locking hole 21, the filter body 31 is held in a closed state; when the locking member 322 disengages from the locking hole 322, the filter body 31 is switched to an open state.

[0069] Furthermore, the locking component 322 interacts directly or indirectly with the first elastic component 321 to cause the first elastic component 321 to deform and accumulate elastic deformation restoring force during the process of the locking component 322 disengaging from the locking hole 21, and to cause the locking component 322 to move until it engages with the locking hole 21 when the first elastic component 321 releases its accumulated elastic deformation restoring force, thereby keeping the filter body 31 in a closed state.

[0070] Specifically, during the opening of the filter body 31, the user can easily push the locking component 322 out of the locking hole 21. During the pushing of the locking component 322, the locking component 322 moves and directly or indirectly squeezes the first elastic component 321, causing the first elastic component 321 to deform. During the closing of the filter body 31, the user can easily push the filter body 31, causing the first elastic component 321 to release its accumulated elastic deformation recovery force. Under the pushing action of the first elastic component 321, the locking component 322 moves and inserts into the locking hole 21 to achieve cooperation with the locking hole 21.

[0071] Since the locking component 322 and the locking hole 21 are plug-in connected and do not need to be tightly fitted, the user does not need to exert much force to push the locking component 322. Furthermore, during the closing process of the filter body 31, the elastic deformation restoring force accumulated by the first elastic component 322 is used to move the locking component 322. This ingenious design reduces the amount of force required for the user to close the filter body 31.

[0072] Figure 7 This is a schematic structural diagram of an elastic opening and closing mechanism according to an embodiment of the present invention. Figure 8 This is a schematic exploded view of an elastic opening and closing mechanism according to an embodiment of the present invention. In some embodiments, the elastic opening and closing mechanism 32 further includes a fork assembly 323, which interacts directly or indirectly with the first elastic member 321, and the fork assembly 323 is configured to maintain the deformation state of the first elastic member 321 after the filter body 31 switches from a closed state to an open state so as to accumulate elastic deformation restoring force, and to release the first elastic member 321 during the process of the filter body 31 switching from an open state to a closed state so as to allow it to release the accumulated elastic deformation restoring force.

[0073] That is, the deformation state of the first elastic component 321 and the release of the elastic deformation restoring force are achieved through the shift fork assembly 323. The mechanical structure design of the shift fork assembly 323 is very ingenious and can replace the traditional buckle and magnetic structure.

[0074] In some embodiments, the shift fork assembly 323 may specifically include a transmission member 3231 and a shift fork 3232.

[0075] The transmission component 3231 is movably disposed between the locking component 322 and the first elastic component 321 to transmit the force between the locking component 322 and the first elastic component 321. The transmission component 3231 is provided with a slot 3233.

[0076] The shift fork 3232 has a head 3234 for engaging with the slot 3233.

[0077] Furthermore, the transmission member 3231 is configured to move under the pushing action of the locking member 322 during the process of switching the filter body 31 from a closed state to an open state, thereby pressing the first elastic member 321 and causing the head 3234 of the shift fork 3232 to engage with the slot 3233. That is, the transmission member 3231 moves under the pushing action of the locking member 322 to press the first elastic member 321 and cause the head 3234 of the shift fork 3232 to engage with the slot 3233.

[0078] Furthermore, the shift fork 3232 is configured to abut against the air inlet grille 20 during the process of the filter body 31 switching from the open state to the closed state, and move under the abutment action of the air inlet grille 20 so that the head 3234 moves out of the slot 3233, thereby releasing the transmission member 3231. When the transmission member 3231 is released, the squeezing action of the transmission member 3231 on the first elastic member 321 is released, which is equivalent to releasing the elastic deformation restoring force of the first elastic member 321. The first elastic member 321 restores its deformation and pushes the transmission member 3231 to move during the process of restoring its deformation. The transmission member 3231 then pushes the locking member 322 to move so that it engages with the locking hole 21.

[0079] In some embodiments, the fork 3232 further includes a tail portion 3235 for abutting against the air intake grille 20, the tail portion 3235 extending protruding toward the air intake grille 20 so as to contact the air intake grille 20 before other structures.

[0080] Furthermore, the fork 3232 is configured to rotate about its pivot 3236 located between the head 3234 and the tail 3235, so that the head 3234 can engage with or disengage from the slot 3233. That is, the fork 3232 moves by rotation. This movement facilitates the use of the contact between the fork 3232 and the air inlet grille 20 during the closing of the filter body 31, and cleverly transforms this into a switching of the relative state between the head 3234 and the slot 3233.

[0081] In some embodiments, the elastic opening and closing mechanism 32 further includes a second elastic component 324. The second elastic component 324 is disposed on the side of the tail of the shift fork 3232 away from the air intake grille 20 and elastically abuts against the tail 3235 of the shift fork 3232. The second elastic component 324 is configured to deform under the squeezing action of the tail of the shift fork 3232 when the tail 3235 of the shift fork 3232 abuts against the air intake grille 20 to accumulate elastic deformation recovery force. When the locking component 322 disengages from the locking hole 21, the accumulated elastic deformation recovery force is released to cause the shift fork 3232 to rotate, thereby causing the tail 3235 of the shift fork 3232 to gradually separate from the air intake grille 20 and causing the head 3234 of the shift fork 3232 to engage with the slot 3233.

[0082] Specifically, during the later stages of the filter body 31 gradually closing, the contact between the tail 3235 of the fork 3232 and the air inlet grille 20 becomes increasingly stronger, and the second elastic component 324 continuously accumulates increasingly greater elastic deformation restoring force until the locking component 322 engages with the locking hole 21. Under the action of the locking component 322 and the locking hole 21, the tail 3235 of the fork 3232 continuously abuts against the air inlet grille 20, and the second elastic component 324 maintains a state of accumulating elastic deformation restoring force. When the user pushes the locking component 322 to push it out of the locking hole 21, the engagement between the locking component 322 and the locking hole 21 disappears. The second elastic component 324 releases the accumulated elastic deformation restoring force, restoring the deformation, which can cause the shift fork 3232 to rotate, thereby causing the tail 3235 of the shift fork 3232 to gradually separate from the air intake grille 20 and causing the head 3234 of the shift fork 3232 to engage with the slot 3233.

[0083] As can be seen, by setting the second elastic component 324, the present invention can automatically spring the filter body 31 from the closed state to the open state after the locking component 322 and the locking hole 21 are disengaged. The user only needs to push the locking component 322 out of the locking hole 21, which saves the user's effort and further improves the user experience.

[0084] In some embodiments, the elastic opening and closing mechanism 32 further includes a base plate 325, which is fixedly connected to the filter body 31. One end of the first elastic member 321 and one end of the second elastic member 324 are both fixed to the base plate 325. The locking member 322 and the transmission member 3231 are slidably disposed on the base plate 325. The shift fork 3232 is rotatably supported on the base plate 325. Specifically, the pivot 3236 of the shift fork 3232 is rotatably supported on the base plate 325.

[0085] In other words, the base plate 325 provides support for the other components of the flexible opening and closing mechanism 32. All other components are installed on the base plate 325, so that the flexible opening and closing mechanism 32 forms a whole that can be installed and disassembled as a whole, which facilitates the maintenance and replacement of the flexible opening and closing mechanism 32 and also improves its assembly efficiency.

[0086] Specifically, a groove can be formed in the middle area of ​​both the locking component 322 and the transmission component 3231. The base plate 325 is provided with two sliders that protrude toward the side where the locking component 322 and the transmission component 3231 are located. The two sliders are respectively inserted into the grooves of the locking component 322 and the transmission component 3231 to guide the sliding of the locking component 322 and the transmission component 3231.

[0087] In some embodiments, the elastic opening and closing mechanism 32 further includes a third elastic member 326, which is configured to gradually elastically abut against the locking member 322 during the insertion of the locking member 322 into the locking hole 21 to limit the stroke of the locking member 322 into the locking hole 21 and accumulate elastic deformation restoring force, and to release the accumulated elastic deformation restoring force during the removal of the locking member 322 from the locking hole 21 to cause the locking member 322 to move out of the locking hole 21.

[0088] By incorporating a third elastic component 326, this invention not only limits the insertion stroke of the locking component 322 into the locking hole 21 using its elastic deformation capability, thus preventing excessive insertion and potential interference with other structures, but more importantly, it also utilizes the elastic deformation restoring force accumulated in the third elastic component 326 to promote the removal of the locking component 322 from the locking hole 21. This significantly reduces the pushing force required by the user to disengage the locking component 322 from the locking hole 21, further reducing the user's operational effort and improving the user experience.

[0089] Furthermore, the third elastic member 326 is configured to generate elastic deformation in the opening and closing direction of the filter body 31, and has a guide slope 3261 that gradually tilts toward the locking member 322 in the direction in which the locking member 322 is inserted into the locking hole 21, and the locking member 322 elastically abuts against the guide slope 3261.

[0090] Due to the special inclined direction of the guide ramp 3261, the contact between the locking component 322 and the guide ramp 3261 becomes increasingly stronger as the locking component 322 is inserted into the locking hole 21, and the elastic deformation restoring force accumulated by the third elastic component 326 becomes increasingly larger. Also due to the special inclined direction of the guide ramp 3261, the elastic deformation restoring force accumulated by the third elastic component 326 is continuously released as the locking component 322 moves out of the locking hole 21. During this process, the third elastic component 326 exerts a force on the locking component 322 opposite to its insertion direction into the locking hole 21, thereby effectively promoting the locking component 322 to move out of the locking hole 21 faster and smoother, reducing the force required by the user.

[0091] Specifically, the third elastic component 326 can be an elastic cantilever with one end fixed to or integrally formed with the base plate 325 and the other end suspended.

[0092] In some embodiments, the locking hole 21 is provided on the edge of the air intake grille 20 to facilitate user operation of the locking component 322.

[0093] In some embodiments, the locking member 322 is configured to slide inward and outward in a horizontal direction such that its outer end portion 3221 is inserted into the locking hole 21 from the inside out and removed from the locking hole 21 from the outside inward.

[0094] In some embodiments, the third elastic member 326 is used to elastically abut against the inner end portion 3222 of the locking member 322, which is opposite to its outer end portion 3221. The inner end portion 3222 extends upward to facilitate the proper arrangement of the third elastic member 326 and to facilitate the abutment of the third elastic member 326 against the inner end portion 3222.

[0095] In some embodiments, the locking member 322 has a first engaging ramp 3223 adjacent to its inner end 3222 and facing downward. The transmission member 3231 is configured to slide vertically and has a second engaging ramp 3237 located at its top. The first engaging ramp 3223 and the second engaging ramp 3237 are slidably engaged together. A first elastic member 321 is disposed below the transmission member 3231 and abuts against the bottom of the transmission member 3231.

[0096] Specifically, the first mating inclined surface 3223 and the second mating inclined surface 3237 both gradually slope downwards along the insertion direction of the locking component 322.

[0097] Specifically, the third elastic component 326 can be an elastic cantilever with one end fixed to or integrally formed with the base plate 325 and the other end suspended.

[0098] Specifically, the first elastic component 321 can be a suitable elastic component such as a compression spring, a spring, or an elastic ring.

[0099] In some embodiments, the first side 311 of the filter body 31 is pivotally connected to the main housing 10 or the air inlet grille 20, and the elastic opening and closing mechanism 32 is disposed on the second side 312 of the filter body 31 opposite to the first side 311.

[0100] That is, the user can open or close the filter body 31 from the second side 312. During the opening and closing process, the filter body 31 always pivots around its first side 311.

[0101] In some embodiments, the first side portion 311 of the filter body 31 is provided with at least one second rotating shaft 313. The air inlet grille 20 is provided with at least one shaft hole that corresponds to and is adapted to the at least one second rotating shaft 313.
