Description

Technical Field

[0001] The invention relates to the technical field of cooking appliances such as steamers and ovens, in particular to a cooking appliance with a steaming function and a water tank that can be taken out and put away. 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. Due to the influence of the cabinet installation space, the panel needs to be flipped forward or sideways to take out the water tank. If the panel is flipped sideways, the cooking appliance will occupy a larger space. If the panel is pushed forward directly, it will make it difficult to take out the water tank inside the panel. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a cooking appliance with a water tank that can be taken out gradually during the movement of the panel, in view of the current status of the prior art. The structure makes the taking and placing of the water tank more comfortable and convenient.

[0006] Another technical problem to be solved by the present invention is to provide a cooking appliance with a water tank that can be taken out and placed, based on the current status of the existing technology. The cooking appliance can move the panel forward a certain distance and then shift upward, and the water tank can be taken out and placed during the shifting process. After the water tank is partially taken out, it is more convenient to take and place, and is convenient to use.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a cooking appliance with a removable water tank, comprising a panel located on the front side of the cooking appliance, a water tank assembly arranged on the rear side of the panel, and a top plate arranged below the panel and the water tank assembly;

[0008] It is characterized by: it also includes a panel driving mechanism capable of driving the panel to move toward the upper front side;

[0009] 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 assembly;

[0010] When the panel is driven and opened, the panel is positioned above and in the front of its position in the reset state, so that at least the front side of the water tank assembly is exposed to the outside.

[0011] The panel driving mechanism of the present invention comprises

[0012] A sliding member is disposed on the top plate so as to be movable forward and backward;

[0013] 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;

[0014] 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

[0015] A first guide post, disposed on a side wall of the first connecting rod and guidingly matched with the first guide groove; and

[0016] The driving mechanism is used to drive the sliding member to move forward and backward.

[0017] 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.

[0018] Preferably, a connection assembly is provided between the water tank assembly and the panel driving mechanism, which can keep the horizontal displacement of the water tank assembly and the panel consistent in the front-to-back direction. This structure keeps the displacement of the water tank assembly and the panel consistent in the horizontal direction, while limiting the displacement of the water tank assembly in the up-down direction, so as to avoid the water tank assembly colliding with the inner wall or edge of the accommodating space during the pulling-out process, thereby affecting the normal pulling-out of the water tank assembly.

[0019] In order to facilitate connection, the connection assembly at least includes a connection plate, one side of the connection plate is connected to the side wall of the water tank assembly, and the other side of the connection plate is connected to the sliding member and moves synchronously with the sliding member.

[0020] 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.

[0021] The water tank removal mechanism of the present invention also includes a limit assembly that can prevent the water tank assembly from moving backward when the water tank assembly is pulled out. When the panel is parked at the front and upper part of the accommodating space, the front part of the water tank assembly is exposed at the front port of the accommodating space, but most of the water tank assembly is still in the accommodating space. At this time, careless human touch may cause the water tank assembly to move backward, or even cause the panel to move downward, affecting use. The above structure avoids this problem.

[0022] As an improvement, the limit assembly includes a limit block, a limit column that can cooperate with the limit block to limit, and a release mechanism that can release the limit block and the limit column from limiting the state. The limit block is arranged on the top plate and is located below the water tank assembly. The release mechanism can be rotatably arranged on the water tank assembly. The limit column is arranged on the release mechanism and can rotate synchronously with the release mechanism. With the above structure, when the water tank assembly is in the pushed-out state, the position of the water tank assembly can be limited by the limit block and the limit column to prevent the water tank from moving backwards under non-human subjective operation; when the panel is to cover the front port of the accommodating space, the panel driving mechanism moves backward and drives the release mechanism to rotate at the same time, thereby canceling the limiting effect of the limit block and the limit column, and the water tank assembly returns to the accommodating space with the movement of the panel.

[0023] Preferably, at least the rear portion of the limit block is formed as a first inclined surface that gradually tilts backward from top to bottom, and correspondingly, the bottom surface of the limit column is formed as a second inclined surface that gradually tilts backward from bottom to top, and the release mechanism is provided with an elastic member that can keep the limit column always in a downward movement trend, and when the water tank assembly is in a forward moving state, the second inclined surface of the limit column cooperates with the first inclined surface to slide until the rear side wall of the limit column and the front side wall of the limit block are engaged and limited. With the above structure, during the process of pushing out the water tank assembly, when the first inclined surface contacts the second inclined surface, the elastic member is compressed, and the water tank assembly continues to drive the limit column to move forward until the rear side wall of the limit column and the front side wall of the limit block are engaged and limited.

[0024] Preferably, the rear side surface of the limit block is formed into a first inclined surface that gradually tilts backward from bottom to top, and the front side surface of the limit block is formed into an arc-shaped groove that gradually concave downward and backward. Correspondingly, the lower end of the limit column is formed into a semicircular arc surface that convexes downward. The release mechanism is provided with an elastic member that can keep the limit column always moving downward. When the water tank assembly moves forward, the semicircular arc surface of the limit column cooperates with the first inclined surface to slide until the lower end of the limit column and the arc groove of the limit block are engaged and limited. When the water tank assembly is pushed backward by artificial force, the semicircular arc surface at the lower end of the limit column slides away from the arc groove of the limit block and passes over the limit block backward to release the limit of the water tank assembly. This structure can manually reset the panel and the water tank assembly when the panel and the water tank assembly are removed but the power is suddenly cut off.

[0025] Preferably, the release mechanism includes a mounting seat and a guide structure, the mounting seat can be rotatably arranged on the rear side wall of the water tank assembly and arranged close to the panel drive mechanism, the limit column can be movably arranged on the mounting seat up and down, the guide structure can be movably arranged on the panel drive mechanism forward and backward, the guide structure has a limit opening gradually offset from the side of the panel drive mechanism to the limit block, the bottom of the mounting seat extends downward to form a plug-in column that can be inserted into the limit opening, when the plug-in column is located at the rear of the limit opening, the lower end of the plug-in column is aligned with the limit block, and when the plug-in column is located at the front of the limit opening, the lower end of the plug-in column is mutually misaligned with the limit block. The above structure realizes whether the release mechanism is triggered or not.

[0026] In the above scheme, the bottom of the guide structure is provided with a first clamping foot and a second clamping foot arranged in a front-to-back spacing. Correspondingly, the panel driving mechanism is provided with a limiting groove that can limit the guide structure in the area. When the first clamping foot is in contact with the front end wall of the limiting groove, the plug-in column is located at the front of the limiting opening. When the second clamping foot is in contact with the rear end wall of the limiting groove, the plug-in column is located at the rear of the limiting opening. The above structure is mainly provided to limit the moving state of the guide structure, so that when the water tank assembly is pulled out, the release mechanism is in an invalid state, and when the water tank assembly needs to be returned to the accommodating space, the release mechanism is in an effective state, thereby releasing the limit on the water tank assembly.

[0027] To facilitate installation and assembly, an installation bin for installing a limiting column is opened upward at the bottom of the mounting seat, the elastic member is arranged at the top of the installation bin and abuts against the upper end of the limiting column, and a toggle member is arranged on one side of the mounting seat to prevent the limiting column from falling out of the installation bin.

[0028] Preferably, the toggle member is rotatably arranged on the mounting seat, a notch is formed on the side wall of the limit column facing the toggle member, and a toggle piece that can be inserted into the notch is formed on the side wall of the toggle member and extends outward. The toggle member has a cylindrical main body, and a mounting sleeve for mounting the main body is formed on the mounting seat, and the mounting sleeve is open near the limit column. A mounting shaft is provided in the middle of the mounting sleeve, and the main body is rotatably sleeved on the mounting shaft.

[0029] Preferably, a first protrusion and a second protrusion are arranged at intervals on the side wall of the main body part, the first protrusion is arranged opposite to the paddle, the second protrusion is located between the first protrusion and the paddle, a first limiting opening for the first protrusion to be inserted into the inner wall of the mounting sleeve is provided, and a second limiting opening for the second protrusion to be inserted into the peripheral wall of the mounting sleeve is provided to prevent the paddle from falling out of the notch.

[0030] In order to improve the stability of the release mechanism, a guide column extending outward is provided on the rear side wall of the water tank assembly, and correspondingly, a guide opening is formed on the mounting seat, which can cooperate with the guide column to keep the mounting seat on the rotation track. A roller is provided on the rear side wall of the water tank assembly, and correspondingly, a guide surface is formed on the top of the mounting seat, which can cooperate with the roller to keep the rotation track.

[0031] In the above scheme, the movement trajectory of the panel driven by the panel driving mechanism is L-shaped with a smooth transition at the bend, and the shape of the first guide groove matches the above L-shaped movement trajectory. Such a movement trajectory enables the panel 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 to slide upward. The process of the rear section moving forward and sliding upward is to avoid the panel from hitting the outer wall of the installation space (such as the edge of the cabinet countertop) during the movement process while keeping the displacement of the front section small. When the panel moves to the upper part of the accommodating space through the sliding process of the rear section, the angle between the panel and the front end of the accommodating space gradually increases from top to bottom. When the panel completely stays at the front upper position of the accommodating space, a suitable angle is maintained between the lower part of the panel and the front end of the accommodating space. On the basis of maintaining the appearance of the panel facing the user, it is more convenient to take out or put in the water tank installed in the accommodating space.

[0032] Preferably, the L-shaped motion track includes a horizontal section, a vertical section and an arc section, the horizontal section extends forward and backward on the top plate, the vertical section is vertically arranged in front of the horizontal section, and the arc section is connected between the horizontal section and the vertical section and arches downward. This structure provides conditions for the formation of the panel track and makes the entire motion stroke of the panel smooth.

[0033] Preferably, the first connecting rod is provided with a second guide groove near the first end and arranged along the length direction of the first connecting rod, and the side wall of the sliding member is provided with a second guide column that can be rotatably connected to the second guide groove and slide back and forth along the guide groove. This structure provides a guide space for the relative rotation of the rear end of the first connecting rod, which can greatly reduce the movement resistance of the panel, reduce the energy consumption of the driving mechanism, and increase the sliding speed of the panel.

[0034] As an improvement, the panel movement structure further includes a second connecting rod, the first end of which is rotatably connected to the side wall of the sliding member and the connection point is located at the rear side of the first guide column, and the second end of the second connecting rod is rotatably connected to the first connecting rod through the first guide column. Since the guide member will generate a large reaction force on the first guide column at the front end of the first connecting rod, if the second connecting rod is not provided, the driving mechanism will be subjected to a large irregular force and a large load. The provision of the second connecting rod can effectively reduce the load of the driving mechanism and make the panel run more smoothly and stably.

[0035] In order to make the sliding part slide smoothly, a guide part arranged along the length direction is provided on the outer side wall of the sliding part, and correspondingly, a guide rail extending forward and backward is provided on the top plate, and a third guide groove for the guide part to slide forward and backward is provided on the side of the guide rail. A limiting column capable of preventing the guide part from escaping from the third guide groove is provided at the rear end of the third guide groove.

[0036] Preferably, the driving mechanism comprises a motor and a gear and rack transmission assembly capable of connecting the output shaft of the motor with the sliding member.

[0037] Further preferably, the gear and rack transmission assembly includes a first rack, a second rack, a third rack, a first gear, a second gear and a third gear, the sliding members are two and are arranged on both sides of the top plate respectively, the first rack is arranged on the sliding member on one side of the panel, the second rack is arranged on one side of the first rack and moves synchronously with the first rack, the first gear is connected to the output shaft of the motor and meshes with the second rack for transmission, the second gear meshes with the first rack for transmission, the third gear is connected to the second gear through the first connecting shaft and meshes with the third rack for transmission, and the third rack is arranged on the sliding member on the other side of the panel. Support seats are arranged on the top plate respectively close to the two sliding members, and the two ends of the above-mentioned first connecting shaft are rotatably supported on the support seats.

[0038] In order to facilitate assembly, the sliding member on one side of the panel extends to one side to form a mounting groove for accommodating the second rack, and the second rack is arranged in the mounting groove. The outer side of the mounting groove is provided with a first stopper that can prevent the second rack from escaping upward from the mounting groove. The mounting groove is formed in a U shape, and a step arranged lower than the upper edge of the mounting groove is formed on the outer side wall of the second rack, and a pressing portion that can be pressed on the step is formed on the top of the first stopper, and the lower part of the first stopper is buckled on the outer side wall of the mounting groove by a buckle.

[0039] Preferably, the gear and rack transmission assembly includes a fourth rack, a fifth rack, a fourth gear, a fifth gear, and a sixth gear. There are two sliding members and they are respectively arranged on both sides of the top plate. The fourth rack is provided on the sliding member on one side of the panel. The fourth gear is connected to the output shaft of the motor and meshes with the fifth gear for transmission. The fifth gear meshes with the fourth rack for transmission and is connected to the sixth gear through the second connecting shaft. The sixth gear meshes with the fifth rack for transmission. The fifth rack is provided on the sliding member on the other side of the panel.

[0040] Preferably, both ends of the first guide groove are provided with a clamping groove extending outward, and a buffering member capable of buffering the movement trend of the first guide post is arranged in the clamping groove. The buffering member has a positioning portion that can be embedded in the clamping groove and a contact portion that is located in the first guide groove and can contact the first guide post, and the contact portion is formed into an arc structure extending along the inner end surface of the first guide groove. This structure can reduce the impact of the guide member on the first guide post, increase the service life of the components, and reduce noise.

[0041] Compared with the prior art, the panel of the cooking appliance of the present invention can be opened and reset under the drive of the panel driving mechanism. In the fully opened 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. The water tank is partially brought out when the panel is docked without the need for manual removal, and the water tank is more comfortable and convenient to take and put.

[0062] The present invention is further described in detail below with reference to the accompanying drawings.

[0063] Embodiment 1:

[0064] like Figures 1 to 11 , Figures 13 to 19 As shown in FIG. 1 , a preferred embodiment of the cooking appliance with a water tank that can be taken out and put in is shown. 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 water tank b installed at the rear thereof to be taken out and put in. Of course, the water tank b can also be replaced by other equipment required by the cooking appliance 10, such as a condiment box, etc., see FIG. Figure 1-2 The cooking appliance 10 is installed in the installation space 20 provided by the cabinet, see Figure 3As 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.

[0065] 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 water tank assembly 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 assembly b is exposed outside the front port of the accommodating space 100. The front side of the water tank assembly b has a removable water box, and the above structure is not easy to interfere with the placement and removal of the water tank assembly.

[0066] The panel driving mechanism 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. 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.

[0067] 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. In the process of the panel 2 moving 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 assembly b installed in the accommodating space 100.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] A connecting assembly c is provided between the water tank assembly b and the panel driving mechanism a of the present embodiment, which can keep the horizontal displacement of the water tank assembly b and the panel 2 in the front-back direction consistent. This structure keeps the displacement of the water tank assembly b and the panel 2 in the horizontal direction consistent, and limits the displacement of the water tank assembly b in the up-down direction, so as to avoid the collision of the water tank assembly 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 assembly b. In order to facilitate the connection, the connecting assembly c includes a connecting plate c1 and an elastic member c2, one side of the connecting plate c1 is connected to the side wall of the water tank assembly b, and the other side of the connecting 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 connecting plate c1 and the first connecting rod 5 and keeps the first connecting rod 5 in a trend of moving forward. The elastic member c2 of the present embodiment is a torsion spring, and the connecting plate c1 has an extension plate extending horizontally outward from the side wall of the water tank assembly b, the first end of the torsion spring is connected to the upper surface of the extension plate of the connecting 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.

[0073] The water tank removal mechanism of this embodiment also includes a limiter assembly d that can prevent the water tank assembly b from moving backward when the water tank assembly b is pulled out. When the panel 2 is parked at the front and upper part of the accommodating space 100, the front part of the water tank assembly b is exposed at the front end of the accommodating space 100, but most of the water tank assembly b is still located in the accommodating space 100. At this time, if someone touches it carelessly, the water tank assembly b may move backward, or even cause the panel 2 to move downward and affect the use. The above structure avoids this problem. The limiting assembly d of this embodiment includes a limiting block d1, a limiting column d2, and a release mechanism e. The limiting block d1 is arranged on the top plate 1 and is located below the water tank assembly b. The release mechanism e is rotatably arranged on the water tank assembly b. The limiting column d2 is arranged on the release mechanism e and can rotate synchronously with the release mechanism e. The position of the limiting block d1 on the top plate 1 corresponds exactly to the position of the limiting column d2 when the front part of the water tank assembly b is pulled out. The limiting column d2 can cooperate with the limiting block d1 to limit the position of the water tank assembly b in the pulled-out state. When the water tank assembly b is in the pushed-out state, the position of the water tank assembly b can be limited by the limiting block d1 and the limiting column d2 to prevent the water tank assembly b from moving backward under non-human subjective operation; when the panel 2 is to cover the front port of the accommodating space 100, the panel driving mechanism a moves backward and drives the release mechanism e to rotate, thereby canceling the limiting effect of the limiting block d1 and the limiting column d2, and the water tank assembly b moves back to the accommodating space 100 with the movement of the panel 2. Specifically, at least the rear portion of the limit block d1 is formed as a first inclined surface d11 which is gradually inclined backward from top to bottom. Correspondingly, the bottom surface of the limit column d2 is formed as a second inclined surface d21 which is gradually inclined backward from bottom to top. The release mechanism e is provided with an elastic member d3 which can enable the limit column d2 to always maintain a downward movement trend. When the water tank assembly b moves forward, the second inclined surface d21 of the limit column d2 cooperates with the first inclined surface d11 to slide until the rear side wall of the limit column d2 is engaged and limited with the front side wall of the limit block d1.

[0074] The release mechanism e of this embodiment includes a mounting seat e1 and a guide structure e2. The mounting seat e1 is rotatably disposed on the rear side wall of the water tank assembly b through a rotating shaft e0 and is arranged close to the panel driving mechanism a. The limit column d2 is disposed on the mounting seat e1 so as to be movable up and down. The guide structure e2 is disposed on the panel driving mechanism a so as to be movable forward and backward. The guide structure e2 has a limit opening e21 which is gradually offset from the side of the panel driving mechanism a toward the limit block d1. The bottom of the mounting seat e1 extends downward to form a plug-in column e11 which can be inserted into the limit opening e21. When the plug-in column e11 is located at the rear of the limit opening e21, the lower end of the plug-in column e11 is aligned with the limit block d1. When the plug-in column e11 is located at the front of the limit opening e21, the lower end of the plug-in column e11 is misaligned with the limit block d1. This structure can realize whether the release mechanism e is triggered or not. The bottom of the guide structure e2 is provided with a first foot e22 and a second foot e23 arranged in a front-to-back interval. Correspondingly, the panel driving mechanism a is provided with a limiting groove a1 which can limit the guide structure e2 in the region. When the first foot e22 abuts against the front wall of the limiting groove a1, the plug-in column e11 is located at the front of the limiting opening e21. When the second foot e23 abuts against the rear wall of the limiting groove a1, the plug-in column e11 is located at the rear of the limiting opening e21. The guide structure e2 of this embodiment is directly provided at the front end of the second rack 922 and slightly offset toward the direction of the water tank assembly b. The second rack 922 is provided in the mounting groove 43 so as to be movable forward and backward. The first foot e22 and the second foot e23 are provided on the bottom surface of the second rack 922. The limiting groove a1 is formed on the inner bottom wall of the mounting groove 43. With such a structure, the driving mechanism 9 can directly drive the guide structure e2 to move, so as to cooperate with the water tank assembly b to control the effectiveness of the release mechanism e at the appropriate time. Of course, in this embodiment, the guide structure e2 can also be separately arranged at other positions of the panel driving mechanism a, and a separate driving structure can be provided for its movement, as long as the movement state of the guide structure e2 can be kept compatible with the pulling out or retracting state of the water tank assembly b. The above structure is mainly for limiting the movement state of the guide structure e2, so that when the water tank assembly b is pulled out, the release mechanism e is in an invalid state, and when the water tank assembly b needs to be retracted into the accommodating space 100, the release mechanism e is in an effective state, thereby releasing the limit on the water tank assembly b.

[0075] To facilitate installation and assembly, an installation chamber e12 for installing the limiting column d2 is opened upward at the bottom of the installation seat e1. The elastic member d3 is a spring and is arranged on the top of the installation chamber e12. The elastic member d3 is against the upper end of the limiting column d2. A toggle member d4 is provided on one side of the installation seat e1 to prevent the limiting column d2 from downwardly escaping from the installation chamber e12.

[0076] The toggle member d4 is rotatably arranged on the mounting seat e1, and a notch d22 is formed on the side wall of the limiting column d2 facing the toggle member d4, and a toggle piece d41 is formed on the side wall of the toggle member d4 to be inserted into the notch d22. The toggle member d4 has a cylindrical main body d42, and a mounting sleeve e13 for mounting the main body d42 is formed on the mounting seat e1, and the portion of the mounting sleeve e13 close to the limiting column d2 is open, and a mounting shaft e14 is provided in the middle of the mounting sleeve e13, and the main body d42 is rotatably sleeved on the mounting shaft e14. A protrusion d421 is provided on the side wall of the main body part d42, and a limiting opening e131 for the protrusion d421 to be inserted into is opened on the inner wall of the mounting sleeve e13. When the elastic member d3 is stretched, the protrusion d421 is located in the notch d22, and when the elastic member d3 is compressed, the protrusion d421 is located in the limiting opening e131.

[0077] In order to improve the stability of the release mechanism e, the rear side wall of the water tank assembly b in this embodiment is provided with a guide column b1 extending outward, and correspondingly, the mounting seat e1 is formed with a guide opening e15 that can cooperate with the guide column b1 to keep the mounting seat e1 on the rotation track. The rear side wall of the water tank assembly b is provided with a roller b2, and correspondingly, the top of the mounting seat e1 is formed with an arc-shaped guide surface e16 that can cooperate with the roller b2 to keep the rotation track.

[0078] When the water tank removal mechanism of the present embodiment is used and the water tank assembly b in the accommodating space 100 needs to be removed, 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 is 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 and then slides upward along the arc segment 33 and the vertical segment 32 in the motion trajectory of the front end of the first connecting rod 5, so that The panel 2 stays at a certain angle on the upper front side of the accommodating space 100. In this process, since the water tank assembly b is directly connected to the sliding member 4, as the panel 2 moves, the water tank assembly b also moves with the panel 2 in the horizontal direction until the front part of the water tank assembly b is exposed at the front port of the accommodating space 100, so that the user can take out the water box from the front end of the water tank assembly b. When the water tank assembly b moves forward with the driving mechanism a, when it approaches the end point, the second clamping foot e23 is in a state of abutting against the rear end wall of the limiting groove a1, and the plug-in column e 11 is located at the rear of the limit opening e21. At this time, the contact mechanism e is in an invalid state, and the lower end of the limit column d2 is aligned with the limit block d1. As the water tank component b continues to move forward, the second inclined surface d21 at the lower end of the limit column d2 slides with the first inclined surface d11 of the limit block d1 until the rear side wall of the limit column d2 is locked with the front side wall of the limit block d1. At this time, the water tank component b will not retreat due to non-human subjective operation; when the water tank component b needs to return to the accommodating space 100 and the panel 2 moves the front side of the accommodating space 100 When the port is closed, the driving mechanism 9 runs, first driving the second rack 922 and the guide structure e2 to move backward a certain distance, so that the first clamping foot e22 is in a state of abutting against the front end wall of the limiting groove a1, and the plug-in column e11 is located in front of the limiting opening e21. At this time, the mounting seat e1 rotates, causing the limiting column d2 to shift and become misaligned with the limiting block d1, that is, the release mechanism e takes effect, and the limiting effect on the water tank assembly b is cancelled. The panel driving mechanism a continues to run in reverse, and the water tank assembly b can be withdrawn and the panel 2 can be closed.

[0079] Embodiment 2:

[0080] The difference between this embodiment and embodiment 1 is that the structures of the gear and rack transmission components are different.

[0081] like Fig.12As shown, the gear and rack transmission assembly 92' of this embodiment includes a fourth rack 921', a fifth rack 922', a fourth gear 923', a fifth gear 924', and a sixth gear 925'. The fourth rack 921' is arranged on the sliding member 4' on one side of the panel 2', the fourth gear 921' is connected to the output shaft of the motor 91' and is meshed with the fifth gear 922' for transmission, the fifth gear 922' is meshed with the fourth rack 921' for transmission and is connected to the sixth gear 925' through the second connecting shaft 926', the sixth gear 925' is meshed with the fifth rack 924' for transmission, and the fifth rack 922' is arranged on the sliding member 4' on the other side of the panel 2'.

[0082] It should be noted that the transmission structure between the motor and the sliding member of the present invention is not limited to the gear and rack transmission assembly, and the gear and rack transmission assembly is not limited to the structures listed in Example 1 and Example 2, as long as the forward and backward movement of the sliding member can be achieved.

[0083] Embodiment 3:

[0084] The difference between this embodiment and embodiment 1 is that: Fig. 20 As shown, the matching structure between the limiting block and the limiting column in this embodiment is different from that in embodiment 1. Specifically, the rear side surface of the limit block d1' is formed as a first inclined surface d11' which gradually tilts backward from bottom to top, and the front side surface of the limit block d1' is formed as an arc-shaped groove d12' which is gradually concave downward and backward. Correspondingly, the lower end of the limit column d2' is formed as a semicircular arc surface d21' which protrudes downward. The release mechanism e is provided with an elastic member d3 which can enable the limit column d2' to always maintain a downward movement trend. When the water tank assembly b is in the forward moving state, the semicircular arc surface d21' of the limit column d2' cooperates with the first inclined surface d11' to slide until the lower end of the limit column d2' is engaged and limited with the arc groove d12' of the limit block d1'. When the water tank assembly b is pushed backward by artificial force, the semicircular arc surface d21' at the lower end of the limit column d2' slides away from the arc groove d12' of the limit block d1' and passes backward over the limit block d1', thereby releasing the limit on the water tank assembly b.

[0085] The above structure can manually reset the panel 2 and the water tank assembly b when the panel 2 and the water tank assembly b are removed but the power is suddenly cut off.
