Description

Technical Field

[0001] The invention relates to the technical field of cooking appliances such as steamers and ovens, in particular to a water tank of a cooking appliance with a steaming function and a cooking appliance using the water tank. Background Art

[0002] As people's quality of life continues to improve, kitchen appliances are becoming more and more abundant, and microwave ovens, ovens, steamers, etc. have gradually become essential kitchen appliances for family life. These kitchen appliances not only have relatively single functions, but each product requires a certain amount of kitchen space, and the cost of purchasing them separately is high. In order to effectively utilize kitchen space and reduce purchase costs, currently, the prior art has disclosed an all-in-one machine that integrates the functions of a steamer with a microwave oven and / or an oven.

[0003] For example, the "Microwave Steamer and Oven" disclosed in the Chinese patent with patent number 201320074461.4 (authorization announcement number CN 203168920 U) includes a body, a door frame and a controller installed on the front of the body, a cavity in the body, a transformer installed on the top of the body, a capacitor connected to the transformer, a magnetron connected to the capacitor, and a waveguide box connected to the magnetron, microwaves are transmitted into the cavity through the waveguide box, a microwave agitator is arranged at the microwave inlet in the cavity, a low-speed motor is connected to the microwave agitator, a water container and a steam generator connected to the water container are installed on the side wall of the body, the steam generator is communicated with the cavity in the body, a heating tube is arranged on the top of the cavity in the body, and the heating tube is connected to the controller. For example, the Chinese patent application with application number 201510457051.1 (application publication number CN 105011740 A) discloses a steam oven and microwave oven integrated with a steam inlet on the cooking chamber, which is connected to the steam outlet of the steam generating device. Another example is the Chinese patent with patent number 201410167732.X (authorization announcement number CN 103976641 B) discloses a steam oven with a water tank on top, in which the steam outlet on the top of the evaporator of the steam oven is connected to the steam inlet on the back of the inner pot, and the steam is generated from the evaporator and enters the inner pot.

[0004] In the prior art, whether the steamer is combined with one or both of the functions of a microwave oven and an oven, a water tank needs to be placed in the appliance to provide high-temperature steam for the cooking space. In particular, in embedded cooking appliances, the water tank is often placed above the cooking cavity, and an openable panel is provided on the front side of the cooking appliance to cover the water tank. When taking out the water tank, the panel needs to be removed first, the water tank needs to be moved to the top edge of the cooking cavity, and then the water box in the water tank needs to be pulled out. Regardless of whether the panel is flipped forward, flipped sideways, or moved in other ways, it will be inconvenient to take out and put the water tank box in the water tank due to the visual obstruction of the panel. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a water tank which can make a water box automatically pop out from the water tank so as to facilitate taking and placing.

[0006] Another technical problem to be solved by the present invention is to provide a cooking appliance that can gradually bring out a water tank in response to the current status of the prior art. After the water tank is brought out, the water box automatically pops out from the water tank, thereby providing convenience for the user.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a water tank, including an outer shell and a water box, wherein the outer shell has a first inner cavity, and the front side of the first inner cavity has a first opening connected to the first inner cavity, characterized in that: it also includes

[0008] An inner shell body is disposed in the first inner cavity of the outer shell body so as to be movable forward and backward through the first opening, and the inner shell body has a second inner cavity for accommodating a water box;

[0009] An elastic mechanism, connected to the inner shell and the outer shell and enabling the inner shell to always maintain a tendency to move outward relative to the outer shell;

[0010] A locking structure, used for locking the state of the elastic mechanism when the inner shell is completely hidden in the outer shell; and

[0011] The trigger member is arranged below the locking structure and is used to release the locking state of the locking structure.

[0012] For the convenience of connection, the middle part of the inner shell has a mounting cavity extending forward and backward, the elastic mechanism is arranged in the mounting cavity, and the front end of the elastic mechanism is connected to the inner shell, and the rear end of the elastic mechanism is connected to the outer shell.

[0013] The locking structure includes

[0014] A mounting seat is arranged in the mounting cavity and extends along the front-rear direction of the mounting cavity, a slide groove arranged along the length direction is opened on the rear side of the mounting seat, and the rear end of the slide groove is bent downward to form a limiting area;

[0015] A locking member is slidably disposed in the slide slot, wherein when the rear portion of the locking member corresponds to a non-limiting zone of the slide slot, the elastic mechanism is in a working state, and when the rear portion of the locking member corresponds to a limiting zone of the slide slot, the elastic mechanism is in a locked state; and

[0016] The elastic member is connected to the locking member and enables the locking member to always maintain a tendency to move downward relative to the sliding groove.

[0017] With the above structure, when the rear part of the locking member corresponds to the horizontal section of the slide groove, that is, the non-limiting area, the locking structure is in an unlocked state, and the elastic mechanism can drive the inner shell to move forward relative to the outer shell, thereby bringing the water box out of the outer shell; when the inner shell is manually pushed into the outer shell and the rear part of the locking member corresponds to the limiting area of ​​the slide groove, the elastic member pulls the locking member downward and limits it in the limiting area, locking the elastic mechanism to prevent the inner shell from driving the water box forward in a non-set state.

[0018] To facilitate connection, the rear side of the locking piece has a first limiting portion formed in the shape of a hook, and correspondingly, the middle part of the locking piece extends upward to form a second limiting portion, the top of the mounting cavity has a limiting column extending downward, and a clamping groove is formed between the first limiting portion and the second limiting portion, which can clamp the limiting column so that the locking piece and the inner shell body maintain synchronous movement in the front and rear directions.

[0019] Preferably, the middle part of the locking member is provided with a first axial hole for the first elastic member to pass through, the lower part of the first limiting portion is provided with a second axial hole for the second elastic member to pass through, the first elastic member passes through the first axial hole to movably connect the middle part of the locking member to the slide slot, the second elastic member passes through the second axial hole to movably connect the rear part of the locking member to the slide slot, when the second elastic member is located in the non-limiting area of ​​the slide slot, the elastic mechanism is in a working state, when the second elastic member is located in the limiting area of ​​the slide slot, the elastic mechanism is in a locked state. This structure facilitates the locking and unlocking process of the locking member.

[0020] To facilitate assembly, a connecting plate that can link the first elastic member and the second elastic member is provided on one side of the mounting seat, and a first through hole aligned with the first axial hole is opened at the front of the connecting plate, and the middle part of the first elastic member passes through the first through hole and the slide slot arrangement, and the end of the first elastic member is bent backward and moved closer to the second elastic member; a second through hole aligned with the second axial hole and located below the first through hole is opened at the rear of the connecting plate, and the upper part of the second elastic member passes through the second through hole and the slide slot arrangement, and a trigger part extending downward is formed at the lower part of the second elastic member. When the trigger part is pushed backward, the second elastic member drives the second axial hole to disengage from the slide slot limiting area and move upward to the slide slot non-limiting area.

[0021] In order to facilitate connection, a limiting notch is opened on the front side wall of the sliding groove limiting area, and correspondingly, a sleeve is formed at the end of the second axial hole which can be clamped in the limiting notch to limit the locking state of the locking piece.

[0022] In the above schemes, the rear end of the mounting seat is connected to the outer shell, the front end of the mounting seat is connected to the inner shell, and the elastic mechanism is arranged at the front part of the mounting seat and the rear end is connected to the locking member.

[0023] Preferably, the elastic mechanism is a damper capable of keeping the piston rod in a contracted state relative to the elastic mechanism body at all times, and the piston rod of the damper is connected to the front portion of the locking member.

[0024] In order to facilitate connection, the front portion of the locking member has a connecting hook extending forward from the front side of the second limiting portion, and the connecting hook is connected to the piston rod of the damper.

[0025] Preferably, the rear part of the mounting seat is provided with a stopper extending from the top downward in the front-to-back direction and used to accommodate the locking member, the slide groove is provided on the side wall of the mounting seat and communicates with the mounting groove, and the front part of the locking member is provided with a third limiting portion located below the connecting hook and extending downward, and correspondingly, the mounting groove is through-through and a stopper is formed at the bottom that can be engaged with the third limiting portion to prevent the locking member from moving backward laterally. This structure cleverly prevents the locking member from continuing to move backward laterally when the second shaft hole of the locking member corresponds to the limiting zone. At this time, if the person continues to apply a backward force to the inner shell, the second shaft hole and the second elastic member can be easily pushed downward along the limiting zone, thereby limiting the locking member.

[0026] In order to facilitate connection, the front end of the installation cavity is provided with a first assembly plate connected to the inner shell, the rear end of the installation cavity is provided with a second assembly plate connected to the outer shell, the front end of the installation seat is rotatably connected to the rear side wall of the first assembly plate, and the rear end of the installation seat is rotatably connected to the front side wall of the second assembly plate. The side wall of the installation cavity is provided with a bayonet arranged near the rear end, and correspondingly, the third assembly plate is provided at the upper rear part of the installation cavity and has a buckle corresponding to the bayonet, and the limiting column is provided on the lower surface of the third assembly plate.

[0027] Preferably, the trigger member has a protrusion that can push the trigger portion of the second elastic member backward when the outer shell moves forward. With this structure, it is easy to generate a backward pushing force on the trigger portion at the lower end of the second elastic member to cancel the locking state of the locking member, release the elastic mechanism, and realize that the inner shell drives the water box to move forward.

[0028] A cooking appliance using the water tank comprises a panel located on the front side of the cooking appliance, a water tank arranged on the rear side of the panel, and a top plate arranged below the panel and the water tank;

[0029] It is characterized by: it also includes a panel driving mechanism capable of driving the panel to move toward the upper front side;

[0030] The front end of the panel drive mechanism is connected to the panel, the rear part of the panel drive mechanism is arranged on the top plate, and the side part of the panel drive mechanism is connected to the side wall of the water tank;

[0031] When the panel is driven to be in the open state, the panel is positioned above and in the front of the position in the reset state, so that at least the front side of the water tank is exposed to the outside;

[0032] The triggering member is arranged on the top plate, the front side of the water tank is exposed to the outside, and the inner shell moves outward relative to the outer shell.

[0033] The panel driving mechanism of the present invention comprises

[0034] A sliding member is disposed on the top plate so as to be movable forward and backward;

[0035] A first connecting rod, a first end of which is rotatably connected to a rear end of the sliding member, and a second end of which extends forward and is connected to a panel;

[0036] A guide member, disposed on the top plate and close to the front end of the accommodating space, the guide member being provided with a first guide groove matching the movement trajectory of the panel; and

[0037] A first guide post, disposed on a side wall of the first connecting rod and guidingly matched with the first guide groove; and

[0038] The driving mechanism is used to drive the sliding member to move forward and backward.

[0039] When the driving mechanism drives the sliding member to move forward, the sliding member drives the first connecting rod to slide forward. Since the front part or the middle part of the first connecting rod can be slidably limited in the first guide groove of the guide member through the first guide column, as the first connecting rod moves forward, the panel at the front end of the first connecting rod moves forward and then slides upward along the movement trajectory of the front end of the first connecting rod, thereby realizing the movement of the panel.

[0040] Preferably, a connection assembly is provided between the water tank and the panel driving mechanism, which can keep the horizontal displacement of the water tank and the panel consistent in the front-to-back direction. This structure keeps the horizontal displacement of the water tank and the panel consistent, while limiting the displacement of the water tank in the up-down direction, so as to avoid the water tank colliding with the inner wall or edge of the accommodating space during the pulling-out process, thus affecting the normal pulling-out of the water tank.

[0041] In order to facilitate connection, the connection assembly at least includes a connection plate, one side of which is connected to the side wall of the water tank, and the other side of which is connected to the sliding member and moves synchronously with the sliding member.

[0042] Preferably, the connection assembly further comprises an elastic member, which is connected between the connection plate and the first connecting rod and enables the first connecting rod to maintain a tendency to move forward. The elastic member is a torsion spring, the first end of which is connected to the connection plate, and the second end of which is connected to the side of the first connecting rod. With this structure, when the first guide post on the first connecting rod moves to the middle turning point of the first guide groove, it will be subjected to a large torsion force. At this time, the torsion spring will provide a forward thrust to the first connecting rod to overcome the resistance of the first guide post in the middle of the first guide groove, thereby ensuring a smooth panel removal process and reducing the load of the driving mechanism.

[0043] Compared with the prior art, the advantages of the present invention are: the pop-up mechanism of the present invention can make the inner shell carrying the water box automatically pop out from the water tank outer shell, which provides great convenience for taking and placing the water box; especially when the water tank structure of the present invention is used in a cooking appliance, when in use, the panel can be opened and reset under the drive of the panel driving mechanism. In the fully open state, the panel is located at the upper front position, and the upper front position refers to the direction close to the user and the upper direction. The opened panel is higher than its position in the reset state, so that the space behind the panel in the reset state is completely exposed, and the water tank is partially taken out when the panel is docked. Visually, it is reflected in the sequence of panel flipping, partial taking out of the water tank, and automatic popping out of the water box. The whole process is smooth and orderly, which provides convenience for the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The present invention is further described in detail below with reference to the accompanying drawings.

[0067] Embodiment 1:

[0068] like Figures 1 to 11 13 to 22 show a preferred embodiment of the water tank and the cooking appliance using the water tank of the present invention. In this embodiment, the cooking appliance 10 has a cooking cavity 10a, including a top plate 1 and a water tank b arranged above the cooking cavity 10a, a panel 2 arranged in front of the water tank b, and a panel driving mechanism a for driving the panel 2 to move. The panel 2 is opened and closed for the purpose of taking and placing the water tank b installed at the rear side thereof, see Figure 1-2 The cooking appliance 10 is installed in the installation space 20 provided by the cabinet, see Figure 3 As shown, the portion of the installation space 20 located above the top plate 1 is the accommodating space 100, and the accommodating space 100 has a front port 101. The water tank b is arranged in the accommodating space 100, and the panel 2 is vertically arranged at the position of the front port 101. The panel 2 can be opened and reset under the drive of the panel driving mechanism a, so that the front port 101 can be opened or covered.

[0069] Panel drive mechanism The panel drive mechanism a of this embodiment can move the panel 2 forward and upward relative to the accommodating space 100. The front end of the panel drive mechanism a is connected to the panel 2, and the rear part of the panel drive mechanism a is arranged on the top plate 1. When the panel drive mechanism a drives the panel 2 to open the front port 101 of the accommodating space 100, the lower edge of the panel 2 is higher than the upper wall surface of the front port 101 of the accommodating space 100 or is flush with the upper wall surface. The side wall of the outer shell b1 of the water tank b of this embodiment is connected to the side of the panel drive mechanism a. When the front port 101 of the accommodating space 100 is opened, the panel 2 is parked at the front upper part of the accommodating space 100, and the panel 2 gradually tilts backward from bottom to top, and the front part of the water tank b is exposed outside the front port 101 of the accommodating space 100.

[0070] The water tank b of this embodiment includes an outer shell b1, an inner shell b2, a water box b3, an elastic mechanism b4, a locking structure b5 and a trigger member b6. The outer shell b1 has a first inner cavity b100, and the front side of the first inner cavity b100 has a first opening b12 connected to the first inner cavity b100. The two inner side walls of the inner shell b2 are respectively connected to the inner side walls of the outer shell b1 through sliding rails b21. The inner shell b2 can be pulled out of or pushed into the first inner cavity b100 of the outer shell b1 through the first opening b12. The inner shell b2 has a second inner cavity b200 for placing the water box b3. The front side of the inner shell b2 is provided with a second opening b22 for pulling the water box b3 out of or pushing it into the second inner cavity b200. The elastic mechanism b4 is connected to the inner shell b2 and the outer shell b1 and enables the inner shell b2 to always maintain a tendency to move outward relative to the outer shell b1; the locking structure b5 is used to lock the state of the elastic mechanism b4 when the inner shell b2 is completely hidden in the outer shell b1, and the trigger member b6 is arranged on the top plate 1 below the locking structure b5 and is used to release the locking state of the locking structure b5.

[0071] Specifically, the middle part of the inner shell b2 has a mounting cavity b20 extending forward and backward, the elastic mechanism b4 is arranged in the mounting cavity b20, and the front end of the elastic mechanism b4 is connected to the inner shell b2, and the rear end of the elastic mechanism b4 is connected to the outer shell b1. The locking structure b5 includes a mounting seat b51, a locking member b52, and an elastic member b53. The mounting seat b51 is arranged in the mounting cavity b20 and extends along the front and rear direction of the mounting cavity b20. The rear side of the mounting seat b51 is provided with a slide groove b511 arranged along the length direction, and the rear end of the slide groove b511 is bent downward to form a limiting area b5111, that is, the slide groove b511 is formed as a whole in an L shape, the portion of the slide groove b511 extending horizontally along the length direction of the mounting seat b51 is a non-limiting area b5112, and the portion of the slide groove b511 arranged vertically at the rear end of the mounting seat b51 is a limiting area b5111. The locking member b52 can slide back and forth in the slide groove b511. When the rear of the locking member b52 corresponds to the non-limiting area b5112 of the slide groove b511, the elastic mechanism b4 is in a working state, and the locking member b52 can be pulled forward along the slide groove b511 and the inner housing b2 can be brought out of the outer housing b1. When the rear of the locking member b52 corresponds to the limiting area b5111 of the slide groove b511, the elastic mechanism b4 is in a locked state, and the inner housing b2 is in the outer housing b1 and will not pop out. The elastic member b6 is connected to the locking member b52 and enables the locking member b52 to always maintain a tendency to move downward relative to the slide groove b511.

[0072] The rear side of the locking piece b52 has a first limiting portion b521 formed in a hook shape, and correspondingly, the middle part of the locking piece b52 extends upward to form a second limiting portion b522, and the top of the rear end of the installation cavity b20 has a limiting column b201 extending downward, and a clamping groove b523 is formed between the first limiting portion b521 and the second limiting portion b522, which can clamp the limiting column b201 therein so that the locking piece b52 and the inner shell body b2 maintain synchronous movement in the front and rear directions. A first axial hole b524 is opened in the middle part of the locking member b52 for the first elastic member b531 to pass through, and a second axial hole b525 is opened in the lower part of the first limiting portion b521 for the second elastic member b532 to pass through. The first elastic member b531 passes through the first axial hole b524 to movably connect the middle part of the locking member b52 to the slide groove b511. Regardless of whether the locking member b52 is locked or not, the first axial hole b524 is always located in the non-limiting area b5112 of the slide groove b511. The second elastic member b532 passes through the second shaft hole b525 to movably connect the rear part of the locking member b52 to the slide slot b511. When the second elastic member b532 is located in the slide slot non-limiting area b5112, the elastic mechanism b4 is in a working state. When the second elastic member b532 is located in the slide slot limiting area b5111, the elastic mechanism b4 is in a locked state. This structure facilitates the locking and unlocking process of the locking member b52. The first elastic member b531 and the second elastic member b532 together constitute the elastic member b53.

[0073] A connecting plate b7 is provided on one side of the mounting seat b51, which can link the first elastic member b531 and the second elastic member b532. A first through hole b71 aligned with the first axial hole b524 is opened at the front of the connecting plate b7. The first elastic member b531 is formed into a U shape. The middle part of the first elastic member b531 passes through the first through hole b71 and the non-limiting area b5112 of the slide groove. The end of the first elastic member b531 is bent backward and approached to the second elastic member b532. A slot b73 is provided on the outer wall of the connecting plate b7 for limiting the position of the first elastic member b531 and the second elastic member b532. The rear part of the connecting plate b7 is provided with a second through hole b72 aligned with the second shaft hole b525 and located below the first through hole b71. The upper part of the second elastic member b532 passes through the second through hole b72 and the slide slot b511. The lower part of the second elastic member b532 is formed with a trigger portion b5321 extending downward. When the trigger portion b5321 is moved backward, the second elastic member b532 drives the second shaft hole b525 to break away from the slide slot limiting area b5111 and move upward to the slide slot non-limiting area b5112. A limiting notch b5113 is formed on the front side wall of the slide slot limiting area b5111. Correspondingly, the end of the second shaft hole b525 is formed with a sleeve b526 that can be clamped in the limiting notch b5112 to limit the locking state of the locking member b52.

[0074] The rear end of the mounting seat b51 is connected to the outer shell b1, the front end of the mounting seat b51 is connected to the inner shell b2, and the elastic mechanism b4 is arranged at the front part of the mounting seat b51 and the rear end is connected to the locking member b52. The elastic mechanism b4 of this embodiment is a damper that can keep its piston rod in a contracted state relative to the elastic mechanism b4 body, and the piston rod of the damper is connected to the front part of the locking member b52. The front part of the locking member b52 has a connecting hook b527 extending forward from the front side of the second limiting portion b522, and the connecting hook b527 is connected to the piston rod of the damper. The rear part of the mounting seat b51 is provided with a mounting groove b513 extending from the top to the bottom in the front-to-back direction and used to accommodate the locking member b52. The sliding groove b511 is provided on the side wall of the mounting seat b51 and communicates with the mounting groove b513. The front part of the locking member b52 is provided with a third limiting portion b528 located below the connecting hook b527 and extending downward. Correspondingly, the mounting groove b513 is connected from top to bottom and a stopper b514 is formed at the bottom to be able to engage with the third limiting portion b528 to prevent the locking member b52 from moving backward laterally. This structure is very clever in preventing the locking member b52 from continuing to move backward laterally when the second shaft hole b525 of the locking member b52 corresponds to the limiting area b5111. At this time, if the person continues to apply a backward force to the inner shell b2, the second shaft hole b525 and the second elastic member b532 can be easily pushed downward along the limiting area b5111, thereby limiting the locking member b52. The front end of the installation cavity b20 is provided with a first assembly plate b23 connected to the inner shell b2, the rear end of the installation cavity b20 is provided with a second assembly plate b24 connected to the outer shell b1, the front end of the mounting seat b51 is rotatably connected to the rear side wall of the first assembly plate b23, and the rear end of the mounting seat b51 is rotatably connected to the front side wall of the second assembly plate b24. The side wall of the installation cavity b20 is provided with a bayonet b202 arranged near the rear end, and correspondingly, the third assembly plate b25 is provided at the upper rear part of the installation cavity b20 and has a buckle b251 corresponding to the bayonet b202, and the limiting column b201 is provided on the lower surface of the third assembly plate b25.

[0075] The trigger member b6 is arranged on the top plate 1 and is located below the outer shell b1. The trigger member b6 has a protrusion b61 that can push the trigger portion b5321 of the second elastic member b532 backward when the outer shell b1 moves forward. The rear side wall of the trigger member b6 is formed as an inclined surface gradually inclined upward from the back to the front, and at least the upper part of the front side wall of the trigger member b6 is formed as an inclined surface gradually inclined upward from the front to the back, and the protrusion b61 is located at the top of the inclined surface of the rear side wall of the trigger member b6.

[0076] The panel driving mechanism a of this embodiment includes a sliding member 4, a first connecting rod 5, a second connecting rod 6, a guide member 7, a first guide column 8 and a driving mechanism 9. Among them, the sliding member 4 is arranged on the top plate 1 so as to be movable forward and backward, the first end of the first connecting rod 5 is rotatably connected to the rear end of the sliding member 4, the second end of the first connecting rod 5 extends forward and is connected to the panel 2, the guide member 7 is arranged on the top plate 1 and is arranged near the front end 101 of the accommodating space 100, the guide member 7 is provided with a first guide groove 71 matching the L-shaped motion track 3 of the panel 2, the first guide column 8 is arranged on the side wall of the first connecting rod 5 and is guided and matched with the first guide groove 71, and the driving mechanism 9 is used to drive the sliding member 4 to move forward and backward.

[0077] The panel driving mechanism a of this embodiment drives the panel 2 to move in an L-shaped motion trajectory 3 with a smooth transition in the middle, and the shape of the first guide groove 71 matches the L-shaped motion trajectory 3. Such a motion trajectory enables the panel 2 to move forward and slide upward after moving forward for a certain distance. The forward movement process of the front section is to provide a certain space for the panel 2 to slide upward, and the process of the rear section moving forward and sliding upward is to prevent the panel 2 from hitting the outer wall of the installation space 20 (such as the edge of the countertop of the cabinet) during the movement process while keeping the displacement of the front section small. When the panel 2 moves to the upper part of the accommodating space 100 through the sliding process of the rear section, the angle between the panel 2 and the front end 101 of the accommodating space 100 gradually increases from top to bottom. When the panel 2 completely stays at the front upper position of the accommodating space 100, a suitable angle is maintained between the lower part of the panel 2 and the front end 101 of the accommodating space 100. On the basis of the panel 2 facing the user and maintaining beauty, it is more convenient to take out or put in the water tank b installed in the accommodating space 100.

[0078] The L-shaped motion track 3 includes a horizontal section 31, a vertical section 32 and an arc section 33. The horizontal section 31 is arranged to extend forward and backward on the top plate 1, the vertical section 32 is vertically arranged at the front side of the horizontal section 31, and the arc section 33 is connected between the horizontal section 31 and the vertical section 32 and arches downward. This structure provides conditions for the formation of the motion track of the panel 2 and makes the entire motion stroke of the panel 2 smooth. It should be noted that the arrangement of the horizontal section 31 does not require to be completely consistent with the horizontal plane, and the arrangement of the vertical section 32 does not require to be completely perpendicular to the horizontal plane, as long as the L-shaped motion track of the panel 2 can be realized. The vertical section 32 in this embodiment is arranged at an angle slightly tilted forward from bottom to top to reduce the force applied to the panel drive mechanism a.

[0079] Both ends of the first guide groove 71 are provided with a clamping groove 711 extending outwards, and a buffering member 72 is arranged in the clamping groove 711 to buffer the movement trend of the first guide column 8. The buffering member 72 has a positioning portion 721 that can be embedded in the clamping groove 711 and a contact portion 722 that is located in the first guide groove 71 and can contact the first guide column 8. The contact portion 722 is formed into an arc structure extending along the inner end surface of the first guide groove 71, which can reduce the impact of the guide member 7 on the first guide column 8, improve the service life of the components, and reduce noise.

[0080] The first connecting rod 5 of this embodiment is provided with a second guide groove 51 close to the first end and arranged along the length direction of the first connecting rod 5, and the side wall of the sliding member 4 is provided with a second guide post 41 which can be rotatably connected to the second guide groove 51 and slide back and forth along the second guide groove 51. The first end of the second connecting rod 6 is rotatably connected to the side wall of the sliding member 4 and the connection point is located at the rear side of the first guide post 8, and the second end of the second connecting rod 6 is rotatably connected to the first connecting rod 5 through the first guide post 8. In actual use, the movement of the panel 2 can be achieved without the second connecting rod 6. However, since the guide member 7 will generate a large reaction force on the first guide post 8 at the front end of the first connecting rod 5, if the second connecting rod 6 is not provided, the driving mechanism 9 will be subjected to a large irregular force and a large load. The provision of the second connecting rod 6 can effectively reduce the load of the driving mechanism 9, making the operation of the panel 2 smoother and more stable. In order to make the sliding member 4 slide smoothly, a guide portion 42 arranged along the length direction is provided on the outer side wall of the sliding member 4, and correspondingly, a guide rail 11 extending forward and backward is provided on the top plate 1, and a third guide groove 111 is provided on the side of the guide rail 11 for the guide portion 42 to slide forward and backward. A limiting column 112 is provided at the rear end of the third guide groove 111 to prevent the guide portion 42 from being separated from the third guide groove 111.

[0081] In this embodiment, there are two slide members 4, which are arranged on both sides of the top plate 1, and each slide member 4 is paired with a set of first connecting rod 5 and second connecting rod 6, so that the panel 2 moves smoothly and stably. The driving mechanism 9 includes a motor 91 and a gear and rack transmission assembly 92 that can connect the output shaft of the motor 91 to the slide member 4. The gear and rack transmission assembly 92 includes a first rack 921, a second rack 922, a third rack 923, a first gear 924, a second gear 925 and a third gear 926. The first rack 921 is arranged on the sliding member 4 on one side of the panel 2. The second rack 922 is arranged on one side of the first rack 921 and moves synchronously with the first rack 921. The first gear 924 is connected to the output shaft of the motor 91 and meshes with the second rack 922 for transmission. The second gear 925 meshes with the first rack 921 for transmission. The third gear 926 is connected to the second gear 925 through the first connecting shaft 927 and meshes with the third rack 923 for transmission. The third rack 926 is arranged on the sliding member 4 on the other side of the panel 2. Support seats 928 arranged close to the two sliding members 4 are arranged on the top plate 1. The two ends of the first connecting shaft 927 are rotatably supported on the support seats 928. In order to facilitate assembly, the sliding member 4 on one side of the panel 2 extends toward the inner side of the top plate 1 to form a mounting groove 43 for accommodating the second rack 925, and the second rack 925 is arranged in the mounting groove 43. A first stopper 44 is arranged on the outer side of the mounting groove 43 to prevent the second rack 922 from escaping upward from the mounting groove 43. The mounting groove 43 is formed in a U shape, and a step 9222 arranged lower than the upper edge of the mounting groove 43 is formed on the outer side wall of the second rack 922 near the center of the top plate 1. A pressing portion 441 that can be pressed on the step 9222 is formed on the top of the first stopper 44, and the lower part of the first stopper 44 is clamped on the buckle 432 of the outer side wall of the mounting groove 43 through the bayonet 442.

[0082] A connection assembly c is provided between the water tank b and the panel driving mechanism a of the present embodiment, which can keep the horizontal displacement of the water tank b and the panel 2 in the front-back direction consistent. The structure keeps the displacement of the water tank b and the panel 2 in the horizontal direction consistent, and limits the displacement of the water tank b in the up-down direction, so as to avoid the collision of the water tank b with the inner wall or edge of the accommodating space 100 during the pulling-out process, thereby affecting the normal pulling-out of the water tank b. In order to facilitate the connection, the connection assembly c includes a connection plate c1 and an elastic member c2, one side of the connection plate c1 is connected to the side wall of the water tank b, and the other side of the connection plate c1 is connected to the sliding member 4 and moves synchronously with the sliding member 4. The elastic member c2 is connected between the connection plate c1 and the first connecting rod 5 and keeps the first connecting rod 5 in a tendency to move forward. The elastic member c2 of the present embodiment is a torsion spring, and the connection plate c1 has an extension plate extending horizontally outward from the side wall of the water tank b, the first end of the torsion spring is connected to the upper surface of the extension plate of the connection plate c1, and the second end of the torsion spring is connected to the side of the first connecting rod 5. With this structure, when the first guide post 8 on the first connecting rod 5 moves to the middle arc section 33 of the first guide groove 71, it will be subjected to a large torsion. At this time, the torsion spring will provide a forward thrust to the first connecting rod 5 to overcome the resistance encountered by the first guide post 5 in the middle of the first guide groove 71, thereby making the panel 2 move out smoothly and reducing the load on the driving mechanism 9.

[0083] When the water tank taking-out mechanism of the present embodiment is used and the water tank b in the accommodating space 100 needs to be taken out, the driving mechanism 9 drives the sliding member 4 to move forward, and the sliding member 4 drives the first connecting rod 5 to slide forward. Since the front part or the middle part of the first connecting rod 5 can be slidably limited in the first guide groove 71 of the guide member 7 through the first guide column 8, as the first connecting rod 5 moves forward, the panel 2 at the front end of the first connecting rod 5 moves forward along the arc segment 33 and the vertical segment 32 in the movement trajectory of the front end of the first connecting rod 5 and then slides upward, so that the panel 2 stays on the upper front side of the accommodating space 100 at a certain angle. In this process, since the water tank b is directly connected to the sliding member 4, as the panel 2 moves, the water tank b also moves with the panel 2 in the horizontal direction until the front part of the water tank b is exposed at the front port of the accommodating space 100. In the process of the horizontal forward movement of the water tank b, when the triggering part b532 of the second elastic member b532 When the inner shell b2 contacts the protruding portion b61 of the triggering member b6, an upward force is generated through the elastic member b53, so that the second shaft hole b525 of the locking member b52 moves upward to the non-limiting area b5112 of the sliding groove b511. At this time, the elastic mechanism b4 can drive the locking member b52 to move forward laterally along the sliding groove b511, thereby driving the inner shell b2 to move forward relative to the outer shell b1, and bringing the water box b3 out of the outer shell b1; when the water box b3 After the water is changed, the inner shell b2 is manually pushed into the outer shell b1. When the rear part of the locking member b52 corresponds to the limiting area b5111 of the slide groove b511, the elastic member b53 pulls the locking member b52 downward and limits it in the limiting area b5111. At this time, the elastic mechanism b4 is in a locked state, preventing the inner shell b2 from driving the water box b3 to move forward in a non-set state; the panel drive mechanism a runs in reverse to complete the withdrawal of the water tank b and the closing of the panel 2.
