In this structure, residual water is prone to be left in the water outlet channel, and when the user takes down the water tank assembly, the residual water in the water tank assembly will drip onto the desktop or the ground, thereby affecting the user experience. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at least to solve the problem of residual water in the water tank assembly of the steam oven in the prior art or related art.

[0004] The first object of the utility model is to provide a water tank device.

[0005] The second object of the utility model is to provide a steam cooking appliance.

[0006] The embodiment of the utility model provides a water tank device for a steam cooking appliance, the water tank device includes: a water tank assembly, the water tank assembly includes a water storage cavity, a water outlet channel and a valve assembly, the water outlet channel is communicated with the water storage cavity, the valve assembly is movably installed in the water outlet channel and can move between a first position and a second position; the water outlet channel includes a water outlet, the valve assembly includes a sealing element, when the valve assembly is located at the first position, the sealing element blocks the water outlet, and when the valve assembly is located at the second position, the sealing element opens the water outlet.

[0007] The water tank device provided by the embodiment of the utility model can be specifically used for a steam cooking appliance, and the steam cooking appliance can be an oven or the like. The water tank device specifically includes a water tank assembly. The water tank assembly includes a water outlet channel, and water in the water tank assembly can be discharged through the water outlet channel. A valve assembly is arranged in the water outlet channel, and the water outlet channel can be opened and closed through the valve assembly.

[0008] In the application, the sealing member is arranged in the water outlet channel and close to the water outlet. When the water tank assembly is not installed on the product, the valve assembly is in the first position, the sealing member blocks the water outlet, and the water in the water tank assembly cannot be discharged through the water outlet channel. After the water tank assembly is installed, the valve assembly is in the second position, at this time, the sealing member is arranged away from the water outlet and opens the water outlet, so that the water outlet and the water inlet are communicated, so that the water in the water tank assembly can be discharged through the water outlet channel to facilitate water supply for the steam cooking appliance. In this structure, the sealing member is installed in the water outlet channel, and when the valve assembly closes the water outlet channel, the sealing member can move along the outlet of the water outlet channel, so that the remaining water in the water outlet channel can be squeezed out through the sealing member, avoiding too much water remaining in the water outlet channel, so that when the water tank assembly is taken out, the water tank assembly can be prevented from leaking and affecting the user experience.

[0009] Further, it can be considered that the water outlet channel is slightly inclined downward from the inlet to the outlet, which can also reduce the residual water in the water outlet channel.

[0010] In any of the above embodiments, optionally, at least part of the water outlet channel is located in the water containing cavity, the water outlet channel comprises a water inlet, the water outlet channel communicates with the water containing cavity through the water inlet, and the water inlet is arranged on the side wall of the part of the water outlet channel located in the water containing cavity.

[0011] In this embodiment, the water inlet is arranged in the water containing cavity, and the water inlet is arranged on the side wall of the water outlet channel, so that the water in the water tank assembly can flow out through the side wall of the water outlet channel. In related schemes, the water inlet is generally arranged at the end of the water outlet channel, so that the water inlet is far away from the water outlet, which does not facilitate opening of the water inlet. In the application, the water inlet is arranged on the side wall of the water outlet channel, so that the water inlet is close to the water outlet, which can shorten the movement distance of the sealing member, so that the sealing member can more easily open the water outlet to communicate the water outlet and the water inlet.

[0012] In any of the above embodiments, optionally, the water tank device further comprises: an elastic member installed in the water outlet channel, one end of the elastic member is connected or abuts against the valve assembly, and the other end of the elastic member is connected or abuts against the inner wall of the water outlet channel, the elastic member is used to drive the valve assembly to move, so that the valve assembly moves from the second position back to the first position.

[0013] In this embodiment, the elastic member is generally a spring. The elastic member is arranged between the valve assembly and the inner wall of the water outlet channel. In the normal state, the elastic member is in a compressed state, and the elastic force of the elastic member can press the sealing member to enable the sealing member to close the water outlet. When the valve assembly is pushed along the water outlet channel, the valve assembly can drive the sealing member to move and open the water outlet channel, so that the water in the water tank assembly can flow out. At the same time, the elastic member is compressed in this process, so that after the external force on the valve assembly disappears, the elastic member can drive the valve assembly to return to the initial position, so that the sealing member closes the water outlet again. Through the arrangement of the elastic member, the automatic reset of the valve assembly can be realized.

[0014] In any of the above embodiments, optionally, the valve assembly further comprises a valve rod which is slidingly arranged in the water outlet channel; and a sealing member which is arranged on the valve rod and in sealing contact with the inner wall of the water outlet channel, and the sealing member can move with the valve rod to open or close the water outlet channel.

[0015] In this embodiment, the valve assembly specifically comprises a valve rod and a sealing member. The valve rod is slidingly arranged in the water outlet channel, and the sealing member is arranged on one end of the valve rod and can move with the valve rod, so that the water outlet channel can be opened or closed by the movement of the sealing member. Through the valve rod, the movement of the sealing member can be driven.

[0016] In any of the above embodiments, optionally, the elastic member and / or the sealing member are sleeved and arranged on the valve rod.

[0017] In this embodiment, the elastic member and the sealing member can be positioned and arranged by the valve rod, and the elastic member and the sealing member can be guided by the valve rod, so that deformation of the elastic member and the sealing member during movement can be avoided.

[0018] In any of the above embodiments, optionally, the water outlet channel comprises a water outlet, and the elastic member is arranged on the side of the sealing member away from the water outlet.

[0019] In this embodiment, the sealing member is arranged close to the water outlet, and in order to avoid interference of the elastic member with the work of the sealing member, the elastic member is arranged on the side of the sealing member away from the water outlet, so that the structure of the product is more reasonable.

[0020] In any of the above embodiments, optionally, two first positioning structures are arranged on the valve rod, the two first positioning structures are arranged in the axial direction of the valve rod and are spaced apart, and the sealing member is arranged between the two first positioning structures.

[0021] In this embodiment, the installation position of the sealing member can be limited by the two first positioning structures, and movement of the position of the sealing member can be avoided, so that the sealing member can reliably seal the water outlet.

[0022] Optionally, the inner side wall of the water outlet channel is provided with a second positioning structure, the valve rod is provided with a third positioning structure, and the elastic member is abutted and installed between the second positioning structure and the third positioning structure.

[0023] In this embodiment, the elastic member is abutted and installed between the valve rod and the water outlet channel, so that the position of the elastic member can be accurately defined through the second positioning structure and the third positioning structure, and deformation of the elastic member is avoided.

[0024] In any of the above embodiments, optionally, one end of the water outlet channel is provided with a water outlet, the other end of the water outlet channel is provided with a flange, the flange extends inwardly from the inner side wall of the water outlet channel in the radial direction of the water outlet channel, the flange surrounds a through hole, the valve rod comprises a first rod portion and a second rod portion arranged in steps, the first rod portion can protrude out of the through hole, the diameter of the first rod portion is smaller than the diameter of the second rod portion, and the elastic member and the sealing member are installed on the second rod portion.

[0025] In this embodiment, the through hole is arranged, so that the valve rod can protrude out of the water outlet channel when moving, so that the length of the water outlet channel can be shortened, and the internal space of the water tank assembly is avoided from being wasted due to the excessively long water outlet channel. At the same time, the end of the valve rod close to the through hole can be arranged to be thin, so that the valve rod forms a stepped structure, and the front end of the valve rod can be conveniently protruded out of the through hole.

[0026] In any of the above embodiments, optionally, the water tank device further comprises: a mounting shell comprising a mounting cavity, one end of the mounting cavity is provided with a mounting opening, and the mounting shell is provided with a push rod; the valve assembly is provided with a slot, the water tank assembly can be inserted and mounted into the mounting cavity through the mounting opening, and when the water tank assembly is located in the mounting cavity, a part of the push rod is inserted into the slot and pushes the valve assembly to move from the first position to the second position to open the water outlet channel.

[0027] In this embodiment, the mounting shell is used to be directly mounted on a product, and the water tank assembly is detachably mounted on the mounting shell, so that the water tank assembly can be individually detached from the tank body, thereby facilitating cleaning of the water tank assembly. At the same time, a push rod can be arranged on the mounting shell, and after the water tank assembly is mounted on the mounting shell, the push rod can be inserted into the water outlet channel to push the valve assembly to move along the water outlet channel, so that the water outlet channel can be opened. When the water tank assembly is removed, the external force of the push rod acting on the valve assembly disappears, and the valve assembly is reset under the resilience of the elastic member, so that the water outlet channel of the water tank assembly is closed, and the water outlet channel of the water tank assembly cannot be watered.

[0028] In order to ensure that the valve assembly and the push rod slip, a slot can also be arranged on the valve assembly, so that one end of the push rod can be inserted into the slot to ensure the stability of the cooperation between the valve assembly and the push rod.

[0029] In any of the above embodiments, optionally, the water tank assembly has a locked state and an unlocked state in the installation cavity, and the elastic member can push a part of the water tank assembly out of the installation housing and move the valve assembly from the second position to the first position to close the water outlet channel when the water tank assembly is in the unlocked state; when the water tank assembly is in the locked state, the elastic member is in a compressed state, and after the water tank assembly is unlocked, the elastic member can be elongated to push a part of the water tank assembly out of the installation housing and move the valve assembly from the second position to the first position to close the water outlet channel.

[0030] In this embodiment, the water tank assembly can be pressed into the installation housing or pushed out of the installation housing. After the water tank assembly is installed, it can be locked in the installation housing. After the water tank assembly is locked, the cooperation between the water tank assembly and the installation housing is good, and the water tank assembly is not easy to shake, so that the water tank assembly is not easy to slide out of the installation housing. When the water tank assembly needs to be filled with water, cleaned or repaired, the water tank assembly can be unlocked to be in an unlocked state. After the water tank assembly is unlocked, the water tank assembly can be taken out of the installation housing.

[0031] When the water tank assembly needs to be detached from the cooking box body for water filling, the water tank assembly can be unlocked first, and after the water tank assembly is unlocked, the external force of the push rod acting on the valve assembly disappears, and the valve assembly is reset to the first position under the action of the elastic member, so that the water outlet channel of the water tank assembly is closed, and the water outlet channel of the water tank assembly cannot outlet water. At the same time, the water tank assembly is pushed out under the action of the elastic member.

[0032] This structure, the elastic member can push the water tank assembly out, and can also make the valve assembly close the water outlet channel, that is, the elastic member for telescopic installation of the water tank assembly and the elastic member required by the valve assembly are the same part, that is, the push-out structure of the water tank assembly and the opening and closing structure of the water outlet of the water tank assembly share an elastic member, so as to simplify the structure of the product.

[0033] Of course, in other schemes, the elastic member for telescopic installation of the water tank assembly and the elastic member required by the valve assembly can also be two independent parts.

[0034] In any of the above technical solutions, optionally, when the water tank assembly is in the locked state, the elastic member is in a compressed state, and after the water tank assembly is unlocked, the elastic member can be elongated to push a part of the water tank assembly out of the installation housing and move the valve assembly from the second position to the first position to close the water outlet channel.

[0035] In the technical solutions, the elastic member is in a compressed state when the water tank assembly is in the locked state. When the water tank assembly is in the unlocked state, the elastic member can be elongated to push the water tank assembly out of the mounting shell. After the water tank assembly is pushed out of the mounting shell, the push rod is separated from the water outlet channel, and the valve assembly is returned to the second position under the action of the elastic member, so as to close the water outlet channel.

[0036] Of course, in other solutions, the elastic member can also be set to an elongated state when the water tank assembly is in the locked state.

[0037] In any of the above technical solutions, optionally, the elastic member comprises a spring capable of being elongated or shortened.

[0038] In the technical solutions, the spring capable of being elongated or shortened can better provide elastic force to push the water tank assembly out when it is needed to be detached from the steam cooking utensil. Meanwhile, the spring can also return the valve body assembly to the initial installation position to block the water outlet channel, so as to avoid water leakage after the water tank assembly is detached from the steam cooking utensil.

[0039] Of course, the elastic member can also be a metal spring, a rubber member or other structures with certain elasticity and hardness.

[0040] In any of the above technical solutions, optionally, the water tank device further comprises: a first limiting member installed on the mounting shell; and a second limiting member arranged on the water tank assembly. When the water tank assembly is located in the mounting cavity, the first limiting member and the second limiting member limit each other to lock the water tank assembly. When the water tank assembly is pressed into the mounting cavity, the limiting between the first limiting member and the second limiting member can be released to unlock the water tank assembly.

[0041] In the technical solutions, the water tank assembly and the mounting shell can be locked and unlocked through the first limiting member and the second limiting member. After the water tank assembly is unlocked, the water tank assembly can be taken out of the mounting shell for water filling, cleaning or maintenance and replacement. After the water tank assembly is locked, the water tank assembly and the mounting shell are well matched, and the water tank assembly is not easy to shake, so that the water tank assembly is not easy to slide out of the mounting shell.

[0042] The water tank assembly only needs to be pushed into the installation shell when the water tank assembly is installed, and when the water tank assembly needs to be taken out, the water tank assembly can be released from the limitation of the elastic member by pressing the water tank assembly, so that the water tank assembly can be separately detached from the product for water filling or cleaning. The disassembly of the water tank assembly does not need to rely on power equipment such as motors, so that the structure of the water tank device can be simplified, and the cost of the water tank device can be reduced. In addition, the second limiting member is arranged on the water tank assembly itself, so that the elastic member can directly act on the water tank assembly itself, thereby the water tank assembly can be directly limited by the first limiting member, so that the limitation of the water tank assembly is more reliable, and the water tank assembly is more stable in the installation shell, so that the water tank assembly is not easy to loosen.

[0043] In addition, the structure for driving the water tank assembly to rebound is directly integrated on the water tank assembly and the installation shell, so that the structure of the entire water tank device is relatively simple, thereby the cost of the product can be reduced. In addition, the water tank assembly itself serves as a rebounding member, so that the pressing and pushing of the water tank assembly are more reliable.

[0044] In any of the above technical solutions, optionally, the water tank assembly comprises a water tank shell, and the second limiting member comprises a limiting structure arranged on the water tank shell.

[0045] In the technical solutions, the water tank assembly comprises a water tank shell, and the water tank shell is used for containing water. The second limiting member is used for limiting the installation position of the water tank assembly in the installation shell. The second limiting member can be directly a limiting structure arranged on the water tank shell, that is, the second limiting member is part of the water tank assembly, specifically, the second limiting member is part of the water tank shell.

[0046] In any of the above technical solutions, optionally, the second limiting member and the water tank shell are in an integral structure.

[0047] In the technical solutions, the second limiting member can be specifically a protruding structure arranged on the water tank shell, or a recessed structure arranged on the water tank shell. The second limiting member and the water tank shell are in an integral structure, so that the connection strength is higher and the reliability is better. Of course, in other solutions, the second limiting member and the water tank shell can be separately arranged, and then the second limiting member is detachably installed on the water tank shell.

[0048] In any of the above technical solutions, optionally, the second limiting member comprises a guide slide, and the guide slide comprises a limiting slot; the first limiting member comprises a movable member, the movable member is installed on the mounting shell, and a part of the movable member is located in the guide slide; when the water tank assembly is installed into the mounting cavity, at least a part of the movable member can be moved from a first end of the guide slide to the limiting slot and be limited in the limiting slot; when the water tank assembly is located in the mounting cavity, the water tank assembly is pressed into the mounting cavity, and at least a part of the movable member can be moved to a second end of the guide slide away from the limiting slot to unlock the water tank assembly.

[0049] In the technical solutions, the first limiting member comprises a movable member, which can be a rotating member or a sliding member. When the water tank assembly is installed in the mounting shell or taken out of the mounting shell, the movable member can move relatively in the guide slide. A limiting slot is arranged in the guide slide, and the movable member can be limited in the limiting slot to ensure that the water tank assembly can be locked and installed at the third position. Then, when the water tank assembly needs to be disassembled, the water tank assembly can be pressed into the mounting shell to move inward, so that the movable member can move to a position away from the limiting slot again, so as to limit the water tank assembly by the movable member, so that the water tank assembly is in an unlocked state. After the water tank assembly is unlocked, the elastic member can rebound to push the water tank assembly to move outward a distance, so as to realize automatic pushing out of the water tank, which is convenient for the user to disassemble the water tank assembly for cleaning, water adding or maintenance.

[0050] In the technical solutions, the first limiting member comprises a movable member, which can be a rotating member or a sliding member. When the water tank assembly is installed in the mounting shell or taken out of the mounting shell, the movable member can move relatively in the guide slide. A limiting slot is arranged in the guide slide, and the movable member can be limited in the limiting slot to ensure that the water tank assembly can be locked and installed at the third position. Then, when the water tank assembly needs to be disassembled, the water tank assembly can be pressed into the mounting shell to move inward, so that the movable member can move to a position away from the limiting slot again, so as to limit the water tank assembly by the movable member, so that the water tank assembly is in an unlocked state. After the water tank assembly is unlocked, the elastic member can rebound to push the water tank assembly to move outward a distance, so as to realize automatic pushing out of the water tank, which is convenient for the user to disassemble the water tank assembly for cleaning, water adding or maintenance.

[0051] Conversely, when the water tank assembly is unlocked, at least a part of the movable member can also move back to the first end of the guide slide until the movable member is separated from the limiting slot.

[0052] In any of the above technical solutions, optionally, the movable member comprises a sliding member, the sliding member can slide along the guide slide, and can be limited in the limiting slot when the water tank assembly is located in the mounting cavity.

[0053] In the technical solutions, the movable part comprises a sliding part. The insertion and removal of the water tank assembly can be realized through the sliding of the sliding part on the guide slide. Meanwhile, after the water tank assembly is inserted and installed in place, that is, the water tank assembly is installed into the installation cavity, the sliding part can be better clamped in the limiting groove. In this way, the sliding of the sliding part can be prevented by the limiting groove, so that the locking of the water tank assembly can be realized. When the water tank assembly needs to be removed again, the water tank assembly can be pressed inward, so that the limiting groove retreats, the sliding part slides out of the limiting groove along the second guide surface, so that the limiting cooperation between the sliding part and the limiting groove is released, and the water tank assembly is in a free state, thereby facilitating the removal of the water tank assembly, and the water tank assembly can be heated, watered, cleaned or repaired and replaced.

[0054] In any of the above technical solutions, optionally, when the water tank assembly is in the locked state, the water tank assembly is located at a third position in the installation cavity, and when the water tank assembly is in the unlocked state, the water tank assembly is located at a fourth position in the installation cavity. The guide slide comprises: a first guide surface; a second guide surface, which is arranged at a first angle with the first guide surface, and the limiting groove is surrounded by the first guide surface and the second guide surface; a first slide, the first guide surface is arranged at a second end of the first slide, and the first slide is used to guide the movement of the sliding part from a first end of the first slide to the first guide surface during the sliding of the water tank assembly from the installation opening into the installation cavity to a fifth position. When the water tank assembly is located at the fifth position, the water tank assembly is loosened, and the water tank assembly moves to the third position outside the installation cavity under the action of the elastic member. The sliding part slides along the first guide surface to the connection between the first guide surface and the second guide surface and is limited at the connection between the first guide surface and the second guide surface; a second slide, one end of the second slide is connected with one end of the second guide surface away from the first guide surface. When the water tank assembly is located at the third position in the installation cavity, the water tank assembly is pressed into the installation cavity, and the sliding part can move into the second slide along the second guide surface. During the sliding of the water tank assembly out of the installation cavity from the installation opening, the sliding part can move along the second slide.

[0055] In the technical solutions, the first guide surface and the second guide surface can be connected to form a limiting groove. After the water tank assembly is installed in place, the sliding part is limited in the limiting groove under the resilience of the elastic member. Through the interaction between the limiting groove and the sliding part, the position of the water tank assembly can be limited, so that the water tank assembly cannot fall out of the installation cavity without other external forces. In order to guide the sliding part to normally enter the limiting groove formed by the first guide surface and the second guide surface, the first slide is arranged. Through the first slide, the sliding part can be guided to move along a preset track. In this way, after the water tank assembly is installed in place, the sliding part can just reach the bottom of the limiting groove, and the sliding part cannot be stuck in advance, so that the water tank assembly cannot be correctly installed.

[0056] When the water tank assembly needs to be disassembled, the water tank assembly can be pressed into the mounting shell, so that the other end of the sliding piece can move along the second guide surface to be separated from the limiting groove, thereby releasing the locking of the water tank assembly by the mounting shell, so that the water tank assembly can be pulled out of the mounting shell, thereby achieving the disassembly of the water tank assembly relative to the mounting shell.

[0057] The guiding slide further comprises a second slide. When the water tank assembly is pulled out of the mounting shell, the sliding piece can slide along the second slide, thereby defining the position of the sliding piece and guiding the water tank assembly to avoid jamming with the mounting shell and other failures.

[0058] In addition, when the water tank assembly is inserted into the mounting shell and pulled out of the mounting shell, the movement path of the sliding piece is inconsistent and forms a loop, thereby making the locking and unlocking cooperation between the sliding piece and the guiding slide more reliable.

[0059] Conversely, the second slide can not be provided, and the structures of the first slide and the first guide surface can be reasonably arranged, so that when the water tank assembly is unlocked, the other end of the sliding piece can return to the first slide along the first guide surface.

[0060] In any of the above technical solutions, the guiding slide further comprises an expansion section arranged at the first end of the first slide, and fourth guide surfaces are arranged on the two inner side walls of the expansion section, the fourth guide surfaces being used to guide the sliding piece to move into the first slide during the sliding of the water tank assembly into the mounting cavity from the mounting opening.

[0061] In these technical solutions, since the sliding piece has a certain sliding range, the position of the sliding piece is not fixed after the water tank assembly is removed. After the water tank assembly is correctly inserted into the mounting shell, the sliding piece can always fall within the range of the expansion section, and when the water tank assembly is inserted inward, the sliding piece can be guided into the first slide by the fourth guide surface. This structure makes the sliding piece be able to slide into the first slide regardless of the initial position, and then move along the fixed track to the limiting part. In this way, before the water tank assembly is installed, the sliding piece does not need to be reset, and the position of the sliding piece does not need to be determined intentionally, thereby making the installation of the water tank assembly more convenient.

[0062] Of course, in other solutions, the expansion section and the fourth guide surface can not be provided, and in this case, in order to ensure that the sliding piece can slide into the first slide, the position of the sliding piece needs to be fixed in advance.

[0063] In any of the above embodiments, the mounting shell is provided with a limiting hole, and the sliding piece is slidably installed in the limiting hole, and the sliding range of the sliding piece can be defined by the limiting hole.

[0064] In the technical solutions, the limiting hole is arranged on the mounting shell to limit the sliding range of the sliding member, so that the sliding member can only move in a predetermined area, thereby limiting the position of the sliding member, avoiding the situation that the sliding member cannot cooperate with the second limiting member on the water tank assembly, and ensuring that the sliding member can always cooperate with the second limiting member to lock the water tank assembly after the water tank assembly is mounted on the water tank shell.

[0065] In any of the above technical solutions, optionally, the movable member comprises a rotating member, a first end of the rotating member being rotatably mounted outside the mounting shell, a limiting hole being arranged on the mounting shell, a second end of the rotating member penetrating through the limiting hole and being inserted into the mounting cavity, the sliding member being arranged on the second end of the rotating member, the sliding member and the rotating member being an integral structure, or the sliding member being detachably connected with the rotating member.

[0066] In the technical solutions, the movable member comprises a rotating member, and the sliding member is arranged on the rotating member. The rotating of the rotating member can drive the sliding member to slide. The structure can conveniently realize the sliding installation of the sliding member.

[0067] The sliding member and the rotating member can form one part, for example, the two are integrally formed or are separately processed and then connected into an integral structure. In addition, the sliding member and the rotating member can also be two completely independent parts.

[0068] In any of the above technical solutions, optionally, the water tank device further comprises a pressing member arranged outside the mounting shell, at least part of the rotating member being located between the pressing member and the mounting shell.

[0069] In the technical solutions, the pressing member is used to press the rotating member towards the water tank assembly, so as to limit the position of the rotating member by the pressing member, so that the rotating member can abut against the water tank assembly, avoiding the situation that the rotating member and the water tank assembly are separated from each other during the rotation.

[0070] In any of the above technical solutions, optionally, the pressing member is elastic, and the pressing member can press the rotating member towards the water tank assembly through elasticity.

[0071] In the technical solutions, the pressing member can be arranged in an elastic structure, so that the rotating member can be pressed by the elastic force of the pressing member, so that the other end of the rotating member can always abut against the water tank assembly, avoiding the situation that the other end of the rotating member is separated from the water tank assembly, and the water tank assembly cannot be locked.

[0072] In any of the above embodiments, optionally, the water tank device further comprises a support structure arranged on the outer wall of the mounting shell and supported on the side of the rotating member close to the mounting shell.

[0073] In this embodiment, in order to limit the height position of the rotating member, a supporting structure is arranged on the mounting shell to support the rotating member, through which the mounting height of the rotating member can be better limited. Meanwhile, through the supporting structure, the contact area between the rotating member and the mounting shell can be reduced to reduce the friction therebetween.

[0074] In any of the above technical solutions, optionally, the water tank assembly comprises a water tank shell comprising a water outlet channel; and a valve assembly installed at the water outlet channel and used for opening or closing the water outlet channel; the mounting shell is provided with a push rod, which is used for being inserted into the water outlet channel and pushing the valve assembly to move when the water tank assembly is installed at the third position, so as to open the water outlet channel; and after the water tank assembly slides out of the mounting cavity, the valve assembly returns to a position for closing the water outlet channel, so that the water outlet channel is closed.

[0075] In the technical solutions, the water tank assembly comprises a water tank shell comprising a water outlet channel, and water in the water tank assembly can be discharged through the water outlet channel. A valve assembly is arranged in the water outlet channel, through which the water outlet channel can be opened and closed. For example, when the water tank assembly is detached from the cooking box body and water is added, the valve assembly can be used to close the water outlet channel to facilitate the addition of water into the water tank assembly. When the water tank assembly is installed on the cooking box body and steam needs to be generated, the water outlet channel can be opened to facilitate the output of water from the water tank assembly.

[0076] In any of the above technical solutions, optionally, the valve assembly comprises a valve rod which is slidably installed in the water outlet channel and can move between a first position and a second position under the action of the push rod; an elastic member which is located in the water outlet channel, one end of the elastic member is connected with the valve rod, and the other end of the elastic member is connected with the inner wall of the water outlet channel; and a sealing member which is installed on the valve rod and can move with the valve rod to open or seal the water outlet channel.

[0077] In this embodiment, the valve assembly specifically comprises a valve rod, an elastic member and a sealing member. The valve rod is slidably installed in the water outlet channel, the sealing member is installed on one end of the valve rod and can move with the valve rod, so that the water outlet channel can be opened or closed through the movement of the sealing member. The elastic member is generally a spring. The elastic member is abutted and installed between the valve rod and the water tank shell, and in a normal state, the elastic member is in a compressed state, the elastic member can compress the sealing member through the elastic force of the elastic member, so that the sealing member can seal the water outlet channel. When the valve rod is pushed along the water outlet channel, the valve rod can drive the sealing member to move and open the water outlet channel, so that the water in the water tank assembly can flow out. Meanwhile, the elastic member is compressed in this process, and therefore, after the external force on the valve rod disappears, the elastic member can drive the valve rod to return to the initial position, so that the sealing member seals the water outlet channel again.

[0078] Specifically, a push rod can be installed on the cooking unit at the position corresponding to the water outlet channel. After the water tank assembly is installed on the cooking unit, the push rod can be inserted into the water outlet channel, thereby pushing the valve rod to move along the water outlet channel, thus opening the water outlet channel. After the water tank assembly is removed, the external force exerted by the push rod on the valve rod disappears, and the valve rod and the seal reset under the action of the elastic force of the elastic element, thereby closing the water outlet channel of the water tank assembly, so that water cannot flow from the water outlet channel of the water tank assembly.

[0079] For example, one end of the valve stem passes through the inlet of the water outlet channel and enters the water-containing chamber. A seal is installed at the inlet of the water outlet channel. Pushing the valve stem along the water outlet channel causes the seal to move away from the outlet, thus opening the inlet of the water outlet channel. In this configuration, the seal is located at the inlet of the water outlet channel, allowing the entire water outlet channel to be opened and closed by using the seal to open or close the inlet.

[0080] In this embodiment, the elastic element used for the telescopic installation of the water tank assembly and the elastic element required for the valve assembly are the same part. That is, the push-out structure of the water tank assembly and the opening and closing structure of the water outlet of the water tank assembly share the same elastic element, which simplifies the structure of the product.

[0081] Of course, in other solutions, the elastic components for the telescopic installation of the water tank assembly and the elastic components required for the valve assembly can also be two separate parts.

[0082] In any of the above technical solutions, optionally, the water outlet channel includes an outlet and an inlet. When the valve stem is in the first position, the seal blocks the outlet. When the valve stem is in the second position, the seal opens the outlet, so that the inlet and outlet are connected.

[0083] A second aspect of this utility model provides a steam cooking appliance, including: a water tank device provided in any embodiment of the first aspect.

[0084] The steam cooking appliance provided according to the embodiments of the present invention includes the water tank device provided in any of the embodiments of the first aspect. Therefore, the steam cooking appliance has all the beneficial effects of the water tank device provided in any of the embodiments of the first aspect, which will not be repeated here.

With this arrangement, the water receiving groove can be directly heated by the existing heating device of the product, and a separate heating structure is not needed, which can simplify the structure of the product. Of course, considering the actual heating requirements, a separate heating structure can also be provided for the water receiving groove.

[0087] Wherein, the box body and the door body constitute the shell structure of the whole product, which forms a cooking box body.

[0088] Further, the first direction can be the front-to-back direction of the box body, for example, the water tank assembly can be disassembled from the front side of the box body. The cover body and the water tank shell of the water tank assembly are also assembled in the front-to-back direction, which is equivalent to that the water tank assembly is installed horizontally on the box body, rather than vertically on the box body. This structure can install the water tank assembly horizontally, which can make the water tank assembly installed relatively high, thereby providing conditions for the water tank assembly to drain by gravity alone.

[0089] Optionally, a first avoiding opening is provided on the box body to avoid the mounting opening, so that the water tank assembly can extend out of the box body.

[0090] Further, the water tank assembly comprises a water tank shell and a cover body, the water tank shell is provided with a water inlet and outlet, and the cover body is detachably covered on the water inlet and outlet of the water tank shell.

[0091] Among them, the water tank assembly arranged on the oven of the related scheme is directly provided with a water adding opening on the side wall of the water tank shell, and no detachable cover is arranged, so that the inside of the water tank cannot be opened, and it is very inconvenient to clean the inside of the water tank. In the present application, a detachable cover body is specially arranged, so that when the water tank assembly needs to be cleaned, the cover body can be opened to clean the inside of the water tank shell, thereby improving the cleaning convenience of the water tank assembly and ensuring the cleanliness of the water tank assembly. At the same time, since the user can open the cover body to observe the inside of the water tank shell, it is convenient for the user to check the dirt inside the water tank assembly in time, so that the user can discover the dirt inside the water tank assembly more quickly, thereby facilitating the user to clean the water tank assembly in time, so that the user can use the water tank assembly more confidently.

[0092] In any of the above embodiments, optionally, the box body includes an inner container, the inner container surrounds the cooking cavity, and the water tank device is installed above the inner container. This arrangement allows the water tank device to be installed higher, thereby facilitating the use of gravity to drain the water tank assembly.

DETAILED DESCRIPTION

[0108] In order to enable the above object, features and advantages of the utility model to be more clearly understood, the following further describes the utility model with reference to the drawings and specific embodiments. It should be explained that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0109] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can be practiced in other ways different from those described herein, therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0110] The embodiments of the present application will be described below with reference to Figures 1 to 8 to describe the water tank device 100 and the steam cooking appliance 200 provided by the embodiments of the present application.

[0111] As Figure 4 and Figure 5 shown, the embodiments of the first aspect of the present application provide a water tank device 100 for a steam cooking appliance 200, the water tank device 100 comprising: a water tank assembly 3, the water tank assembly 3 comprising a water containing cavity 300, a water outlet channel 34 and a valve assembly 36, the water outlet channel 34 being in communication with the water containing cavity 300, the valve assembly 36 being movably mounted in the water outlet channel 34 and being movable between a first position and a second position; the water outlet channel 34 comprising a water outlet opening 342, the valve assembly 36 comprising a sealing member 39, the sealing member 39 blocking the water outlet opening 342 when the valve assembly 36 is in the first position, the sealing member 39 opening the water outlet opening 342 when the valve assembly 36 is in the second position.

[0112] The water tank device 100 provided by the embodiments of the present application can be specifically used in the steam cooking appliance 200, and the steam cooking appliance 200 can be an oven or other products. The water tank device 100 specifically comprises a water tank assembly 3. The water tank assembly 3 comprises a water outlet channel 34, and the water in the water tank assembly 3 can be discharged through the water outlet channel 34. A valve assembly 36 is arranged in the water outlet channel 34, and the valve assembly 36 can open and close the water outlet channel 34.

[0113] In the present application, the sealing member 39 is arranged in the water outlet channel 34 and close to the water outlet opening 342. When the water tank assembly 3 is not installed on the product, the valve assembly 36 is in the first position, and the sealing member 39 blocks the water outlet opening 342, so that the water in the water tank assembly 3 cannot be discharged through the water outlet channel 34. After the water tank assembly 3 is installed, the valve assembly 36 is in the second position, at this time, the sealing member 39 is arranged away from the water outlet opening 342 and opens the water outlet opening 342, so that the water outlet opening 342 and the water inlet opening 344 are in communication, and thus the water in the water tank assembly 3 can be discharged through the water outlet channel 34, to facilitate water supply for the steam cooking appliance 200. In this structure, the sealing member 39 is arranged in the water outlet channel 34, and when the valve assembly 36 closes the water outlet channel 34, the sealing member 39 can move along the outlet of the water outlet channel 34, so that the residual water in the water outlet channel 34 can be squeezed out through the sealing member 39, to avoid that too much water remains in the water outlet channel 34, so that when the water tank assembly 3 is taken out, water leakage of the water tank assembly 3 can be avoided, and the user experience can be affected.

[0114] Further, the water outlet passage 34 can be slightly inclined downward from the inlet to the outlet, so as to reduce the residual water in the water outlet passage 34.

[0115] In any of the above embodiments, optionally, as shown in Figure 4 , Figure 5 and Figure 6 , at least part of the water outlet passage 34 is located in the water storage cavity 300, the water outlet passage 34 comprises a water inlet 344, the water outlet passage 34 communicates with the water storage cavity 300 through the water inlet 344, and the water inlet 344 is arranged on the side wall of the part of the water outlet passage 34 located in the water storage cavity 300.

[0116] In this embodiment, the water inlet 344 is arranged in the water storage cavity 300, and the water inlet 344 is arranged on the side wall of the water outlet passage 34, so that the water in the water tank assembly 3 can flow out through the side wall of the water outlet passage 34. In related solutions, the water inlet 344 is generally arranged at the end of the water outlet passage 34, so that the water inlet 344 is far away from the water outlet 342, which is not conducive to opening the water inlet 344. In the present application, the water inlet 344 is arranged on the side wall of the water outlet passage 34, so that the water inlet 344 is close to the water outlet 342, which can shorten the movement distance of the sealing member 39, so that the sealing member 39 can more easily open the water outlet 342, so that the water outlet 342 and the water inlet 344 are communicated.

[0117] In any of the above embodiments, optionally, as shown in Figure 4 and Figure 5 , the water tank device 100 further comprises a resilient member 4 arranged in the water outlet passage 34, one end of the resilient member 4 is connected or abuts against the valve assembly 36, and the other end of the resilient member 4 is connected or abuts against the inner wall of the water outlet passage 34, and the resilient member 4 is used to drive the valve assembly 36 to move, so that the valve assembly 36 moves from the second position back to the first position.

[0118] In this embodiment, the resilient member 4 is generally a spring. The resilient member 4 is arranged between the valve assembly 36 and the inner wall of the water outlet passage 34, and in the normal state, the resilient member 4 is in a compressed state, and the resilient force of the resilient member 4 can press the sealing member 39, so that the sealing member 39 can close the water outlet 342. When the valve assembly 36 is pushed along the water outlet passage 34, the valve assembly 36 can drive the sealing member 39 to move and open the water outlet passage 34, so that the water in the water tank assembly 3 can flow out. At the same time, the resilient member 4 is compressed in this process, so that after the external force on the valve assembly 36 disappears, the resilient member 4 can drive the valve assembly 36 to reset to the initial position, so that the sealing member 39 closes the water outlet 342 again. Through the arrangement of the resilient member 4, the automatic reset of the valve assembly 36 can be realized.

[0119] In any of the above embodiments, optionally, as shown in Figure 4 and Figure 5 , the valve assembly 36 further comprises a valve rod 38 slidingly installed in the water outlet channel 34, and a sealing member 39 installed on the valve rod 38 and in sealing contact with the inner wall of the water outlet channel 34, the sealing member 39 being capable of moving with the valve rod 38 to open or close the water outlet channel 34.

[0120] In this embodiment, the valve assembly 36 specifically comprises the valve rod 38 and the sealing member 39. The valve rod 38 is slidingly installed in the water outlet channel 34, and the sealing member 39 is installed on one end of the valve rod 38 and is capable of moving with the valve rod 38, so that the water outlet channel 34 can be opened or closed by moving the sealing member 39. In this way, the sealing member 39 can be moved by the valve rod 38.

[0121] In any of the above embodiments, optionally, as shown in Figure 4 and Figure 5 , the elastic member 4 and / or the sealing member 39 are sleeved and installed on the valve rod 38.

[0122] In this embodiment, the elastic member 4 and the sealing member 39 can be positioned and installed by the valve rod 38, and the elastic member 4 and the sealing member 39 can be guided by the valve rod 38, so that deformation of the elastic member 4 and the sealing member 39 during movement can be avoided.

[0123] In any of the above embodiments, optionally, as shown in Figure 4 and Figure 5 , the water outlet channel 34 comprises a water outlet 342, and the elastic member 4 is arranged on the side of the sealing member 39 away from the water outlet 342.

[0124] In this embodiment, the sealing member 39 is arranged close to the water outlet 342, and in order to avoid interference of the elastic member 4 with the work of the sealing member 39, the elastic member 4 is arranged on the side of the sealing member 39 away from the water outlet 342, so that the structure of the product is more reasonable.

[0125] In any of the above embodiments, optionally, as shown in Figure 4 and Figure 5 , the valve rod 38 is provided with two first positioning structures 382, the two first positioning structures 382 are arranged in the axial direction of the valve rod 38 and are spaced apart, and the sealing member 39 is installed between the two first positioning structures 382.

[0126] In this embodiment, the installation position of the sealing member 39 can be defined by the two first positioning structures 382, so that the position of the sealing member 39 cannot be moved, and thus the sealing member 39 can reliably seal the water outlet 342.

[0127] In any of the above embodiments, optionally, as shown inFigure 4 and Figure 5 As shown in FIG. 6, the inner side wall of the water outlet passage 34 is provided with a second positioning structure 346, the valve rod 38 is provided with a third positioning structure 384, and the elastic member 4 is abuttingly installed between the second positioning structure 346 and the third positioning structure 384.

[0128] In this embodiment, the elastic member 4 is abuttingly installed between the valve rod 38 and the water outlet passage 34, so that the position of the elastic member 4 can be accurately defined by the second positioning structure 346 and the third positioning structure 384, and deformation of the elastic member 4 is avoided.

[0129] In any of the above embodiments, optionally, as shown in Figure 4 and Figure 5 As shown in FIG. 6, one end of the water outlet passage 34 is provided with a water outlet 342, the other end of the water outlet passage 34 is provided with a flange 348, the flange 348 extends inwardly from the inner side wall of the water outlet passage 34 along the radial direction of the water outlet passage 34, the flange 348 surrounds a through hole 349, the valve rod 38 includes a first rod portion 386 and a second rod portion 388 arranged in steps, the first rod portion 386 can extend out of the through hole 349, the diameter of the first rod portion 386 is smaller than the diameter of the second rod portion 388, and the elastic member 4 and the sealing member 39 are installed on the second rod portion 388.

[0130] In this embodiment, by providing the through hole 349, the valve rod 38 can extend out of the water outlet passage 34 when moving, so that the length of the water outlet passage 34 can be shortened, and the internal space of the water tank assembly 3 is avoided from being wasted due to the excessively long water outlet passage 34. At the same time, the end of the valve rod 38 close to the through hole 349 can be arranged to be relatively thin, so that the valve rod 38 forms a stepped structure, and the front end of the valve rod 38 can be conveniently extended out of the through hole 349.

[0131] In any of the above embodiments, optionally, as shown in Figure 1 , Figure 4 and Figure 5 As shown in FIG. 6, the water tank device 100 further includes a mounting shell 1 including a mounting cavity 12, one end of the mounting cavity 12 is provided with a mounting opening 14, the mounting shell 1 is provided with a push rod 16, the valve assembly 36 is provided with a slot 389, the water tank assembly 3 can be inserted into the mounting cavity 12 through the mounting opening 14, and when the water tank assembly 3 is located in the mounting cavity 12, a part of the push rod 16 is inserted into the slot 389 and pushes the valve assembly 36 to move from the first position to the second position to open the water outlet passage 34.

[0132] In this embodiment, the mounting shell 1 is used for direct installation on the product, and the water tank assembly 3 is detachably mounted on the mounting shell 1, so that the water tank assembly 3 can be individually detached from the tank 6, thereby facilitating the cleaning of the water tank assembly 3. Meanwhile, a push rod 16 can be arranged on the mounting shell 1, and after the water tank assembly 3 is mounted on the mounting shell 1, the push rod 16 can be inserted into the water outlet passage 34 to push the valve assembly 36 to move along the water outlet passage 34, so as to open the water outlet passage 34, and after the water tank assembly 3 is removed, the external force of the push rod 16 acting on the valve assembly 36 disappears, and the valve assembly 36 is reset under the resilience of the elastic member 4, so as to close the water outlet passage 34 of the water tank assembly 3, so that the water outlet passage 34 of the water tank assembly 3 cannot outlet water.

[0133] In order to ensure the sliding of the valve assembly 36 and the push rod 16, a slot 389 can also be arranged on the valve assembly 36, so that one end of the push rod 16 can be inserted into the slot 389, thereby ensuring the stability of the cooperation between the valve assembly 36 and the push rod 16.

[0134] In any of the above embodiments, optionally, the water tank assembly 3 has a locked state and an unlocked state in the mounting cavity 12, and when the water tank assembly 3 is in the unlocked state, the elastic member 4 can push a part of the water tank assembly 3 out of the mounting shell 1 and move the valve assembly 36 from the second position to the first position to close the water outlet passage 34; when the water tank assembly 3 is in the locked state, the elastic member 4 is in a compressed state, and after the water tank assembly 3 is unlocked, the elastic member 4 can be elongated to push a part of the water tank assembly 3 out of the mounting shell 1 and move the valve assembly 36 from the second position to the first position to close the water outlet passage 34.

[0135] In this embodiment, the water tank assembly 3 can be pressed into the mounting shell 1 or pushed out of the mounting shell 1. After the water tank assembly 3 is installed, it can be locked in the mounting shell 1. After the water tank assembly 3 is locked, the cooperation between the water tank assembly 3 and the mounting shell 1 is good, and the water tank assembly 3 is not easy to shake, so that the water tank assembly 3 is not easy to slide out of the mounting shell 1. When the water tank assembly 3 needs to be filled with water, cleaned or maintained, the water tank assembly 3 can be unlocked to be in the unlocked state. After the water tank assembly 3 is unlocked, the water tank assembly 3 can be taken out of the mounting shell 1.

[0136] When the water tank assembly 3 needs to be detached from the cooking tank 6 for water filling, the water tank assembly 3 can be unlocked first, and after the water tank assembly 3 is unlocked, the external force of the push rod 16 acting on the valve assembly 36 disappears, and the valve assembly 36 is reset to the first position under the action of the elastic member 4, so as to close the water outlet passage 34 of the water tank assembly 3, so that the water outlet passage 34 of the water tank assembly 3 cannot outlet water. Meanwhile, the water tank assembly 3 is pushed out under the action of the elastic member 4.

[0137] In this structure, the elastic member 4 can push the water tank assembly 3 out and also can make the valve assembly 36 close the water outlet passage 34, that is, in this structure, the elastic member 4 required for the telescopic installation of the water tank assembly 3 and the elastic member 4 required for the valve assembly 36 are the same part, that is, the elastic member 4 is shared by the pushing structure of the water tank assembly 3 and the opening and closing structure of the water outlet 342 of the water tank assembly 3, so as to simplify the structure of the product.

[0138] Of course, in other schemes, the elastic member 4 required for the telescopic installation of the water tank assembly 3 and the elastic member 4 required for the valve assembly 36 can also be two independent parts.

[0139] In any of the above embodiments, optionally, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state, and after the water tank assembly 3 is unlocked, the elastic member 4 can be elongated to push a part of the water tank assembly 3 out of the mounting shell 1 and make the valve assembly 36 move from the second position to the first position to close the water outlet passage 34.

[0140] In these embodiments, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state. When the water tank assembly 3 is in the unlocked state, the elastic member 4 can be elongated to push the water tank assembly 3 out of the mounting shell 1, and after the water tank assembly 3 is pushed out of the mounting shell 1, the push rod 16 is separated from the water outlet passage 34, and the valve assembly 36 returns to the second position under the action of the elastic member 4, thereby closing the water outlet passage 34.

[0141] Of course, in other schemes, when the water tank assembly 3 is in the locked state, the elastic member 4 can also be set to the elongated state.

[0142] In any of the above embodiments, optionally, the elastic member 4 includes a spring that can be elongated or shortened.

[0143] In these embodiments, through the spring that can be elongated or shortened, the elastic force can be better provided to push the water tank assembly 3 out when it is required to be detached from the steam cooking utensil 200. At the same time, the spring can also make the valve body assembly return to the initial installation position to block the water outlet passage 34, thereby avoiding water leakage after the water tank assembly 3 is detached from the steam cooking utensil 200.

[0144] Of course, the elastic member 4 can also be a metal spring, a rubber piece or other structures with certain elasticity and hardness.

[0145] In any of the above embodiments, optionally, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state, and after the water tank assembly 3 is unlocked, the elastic member 4 can be stretched to push a part of the water tank assembly 3 out of the mounting shell 1 and to move the valve assembly 36 from the second position to the first position to close the water outlet passage 34.

[0146] In the embodiments, when the water tank assembly 3 is in the locked state, the elastic member 4 is in the compressed state. When the water tank assembly 3 is in the unlocked state, the elastic member 4 can be stretched to push the water tank assembly 3 out of the mounting shell 1, and after the water tank assembly 3 is pushed out of the mounting shell 1, the push rod 16 is separated from the water outlet passage 34, and the valve assembly 36 is returned to the second position under the action of the elastic member 4, thereby closing the water outlet passage 34.

[0147] Of course, in other solutions, when the water tank assembly 3 is in the locked state, the elastic member 4 can also be set to the stretched state.

[0148] In any of the above embodiments, optionally, as shown in Figure 5 and Figure 7 , the elastic member 4 includes a spring capable of being stretched or shortened.

[0149] In the embodiments, through the spring capable of being stretched or shortened, the elastic force can be better provided to push the water tank assembly 3 out when it is needed to be detached from the steam cooking utensil 200. At the same time, the spring can also return the valve body assembly to the initial installation position to block the water outlet passage 34, thereby avoiding water leakage after the water tank assembly 3 is detached from the steam cooking utensil 200.

[0150] Of course, the elastic member 4 can also be a metal spring, a rubber piece or other structures having certain elasticity and hardness.

[0151] In any of the above embodiments, optionally, as shown in Figure 1 , Figure 2 and Figure 3 , the water tank device 100 further includes a first limiting member 2 installed on the mounting shell 1 and a second limiting member 32 provided on the water tank assembly 3. When the water tank assembly 3 is located in the mounting cavity 12, the first limiting member 2 and the second limiting member 32 limit each other to lock the water tank assembly 3. When the water tank assembly 3 is located in the mounting cavity 12 and is pressed into the mounting cavity 12, the limiting between the first limiting member 2 and the second limiting member 32 can be released to unlock the water tank assembly 3.

[0152] In the embodiments, the water tank assembly 3 and the mounting shell 1 can be locked and unlocked by the first limiting member 2 and the second limiting member 32. After the water tank assembly 3 is unlocked, the water tank assembly 3 can be taken out of the mounting shell 1 for water filling, cleaning or maintenance. After the water tank assembly 3 is locked, the water tank assembly 3 and the mounting shell 1 are well matched, and the water tank assembly 3 is not easy to shake, so that the water tank assembly 3 is not easy to slide out of the mounting shell 1.

[0153] In the embodiments, the water tank assembly 3 and the mounting shell 1 can be locked and unlocked by the first limiting member 2 and the second limiting member 32. After the water tank assembly 3 is unlocked, the water tank assembly 3 can be taken out of the mounting shell 1 for water filling, cleaning or maintenance. After the water tank assembly 3 is locked, the water tank assembly 3 and the mounting shell 1 are well matched, and the water tank assembly 3 is not easy to shake, so that the water tank assembly 3 is not easy to slide out of the mounting shell 1.

[0154] In addition, the structure for driving the water tank assembly 3 to rebound is directly integrated on the water tank assembly 3 and the mounting shell 1, so that the structure of the entire water tank device 100 is relatively simple, thereby reducing the cost of the product. In addition, the water tank assembly 3 itself serves as a rebounding member, so that the pressing and pushing of the water tank assembly 3 are more reliable.

[0155] In any of the above embodiments, optionally, as shown in Figure 2 and Figure 3 The water tank assembly 3 comprises a water tank shell 30, and the second limiting member 32 comprises a limiting structure arranged on the water tank shell 30.

[0156] In the embodiments, the water tank assembly 3 comprises a water tank shell 30, and the water tank shell 30 is used for water storage. The second limiting member 32 is used for limiting the installation position of the water tank assembly 3 in the mounting shell 1. In the embodiments, the second limiting member 32 can be directly a limiting structure arranged on the water tank shell 30, that is, the second limiting member 32 is a part of the water tank assembly 3, specifically, the second limiting member 32 is a part of the water tank shell 30.

[0157] In any of the above embodiments, optionally, the second limiting member 32 and the water tank shell 30 are in an integrated structure.

[0158] In the embodiments, the second limiting member 32 can be a protruding structure arranged on the water tank shell 30, or a recessed structure arranged on the water tank shell 30. The second limiting member 32 and the water tank shell 30 are in an integrated structure, so that the connection strength is higher and the reliability is better. Of course, in other solutions, the second limiting member 32 and the water tank shell 30 can be arranged separately, and then the second limiting member 32 is detachably mounted on the water tank shell 30.

[0159] In any of the above embodiments, optionally, as shown in Figure 3 The second limiting member 32 includes a guide slide 320, and the guide slide 320 includes a limiting groove 327. The first limiting member 2 includes a movable member 22, and the movable member 22 is mounted on the mounting shell 1, and a part of the movable member 22 is located in the guide slide 320. When the water tank assembly 3 is mounted into the mounting cavity 12, at least a part of the movable member 22 can move from a first end of the guide slide 320 to the limiting groove 327 and be limited in the limiting groove 327. When the water tank assembly 3 is located in the mounting cavity 12, the water tank assembly 3 is pressed into the mounting cavity 12, and at least a part of the movable member 22 can move to a second end of the guide slide 320 away from the limiting groove 327, so as to unlock the water tank assembly 3.

[0160] In the embodiments, the first limiting member 2 includes a movable member 22, which can be a rotating member 26 or a sliding member 24. When the water tank assembly 3 is mounted in or taken out of the mounting shell 1, the movable member 22 can move relatively in the guide slide 320. The guide slide 320 is provided with a limiting groove 327, and the movable member 22 can be limited by the limiting groove 327, so as to ensure that the water tank assembly 3 can be locked and mounted at the third position. Thereafter, when it is needed to dismount the water tank assembly 3, the water tank assembly 3 can be pressed into the mounting shell 1, so that the water tank assembly 3 moves inwardly, and the movable member 22 can move to a position away from the limiting groove 327 again, so as to limit the water tank assembly 3 by the movable member 22, and make the water tank assembly 3 in an unlocked state. After the water tank assembly 3 is unlocked, the elastic member 4 can rebound, so as to push the water tank assembly 3 to move outwardly from the mounting shell 1 by a distance, so as to realize automatic pushing out of the water tank, and facilitate the user to dismount the water tank assembly 3 for cleaning, water adding or maintenance.

[0161] In the embodiments, when the water tank assembly 3 is pulled out of the mounting shell 1, the movable member 22 can continue to slide as before, instead of sliding back. In this way, when the water tank assembly 3 is inserted into the mounting shell 1 and pulled out of the mounting shell 1, the movement path of the movable member 22 is inconsistent, so as to make the locking and unlocking cooperation between the movable member 22 and the guide slide 320 more reliable.

[0162] Conversely, when the water tank assembly 3 is unlocked, at least part of the movable member 22 can also move back towards the first end of the guide slide 320 until the movable member 22 is separated from the limiting groove 327.

[0163] Figure 3 The arrow in the figure is a schematic diagram of the movement path of the movable member 22.

[0164] In any of the above embodiments, optionally, as shown in Figure 1 、 Figure 2 and Figure 3 , the movable member 22 comprises a sliding member 24, which is capable of sliding along the guide slide 320 and capable of being limited in the limiting groove 327 when the water tank assembly 3 is located in the installation cavity 12.

[0165] In these embodiments, the movable member 22 comprises the sliding member 24. By sliding the sliding member 24 along the guide slide 320, the insertion and removal of the water tank assembly 3 can be achieved. At the same time, after the water tank assembly 3 is inserted and installed in place, that is, when the water tank assembly 3 is installed into the installation cavity 12, the sliding member 24 can be better clamped in the limiting groove 327. In this way, the sliding of the sliding member 24 can be prevented by the limiting groove 327, so that the locking of the water tank assembly 3 can be achieved. When it is necessary to remove the water tank assembly 3 again, the water tank assembly 3 can be pressed inward so that the limiting groove 327 retreats, and the sliding member 24 slides out of the limiting groove 327 along the second guide surface 324. In this way, the limiting fit between the sliding member 24 and the limiting groove 327 can be released, so that the water tank assembly 3 is in a free state, thereby facilitating the removal of the water tank assembly 3, and the water tank assembly 3 can be heated, watered, cleaned or repaired and replaced.

[0166] In any of the above embodiments, optionally, as shown in Figure 3As shown, when the water tank assembly 3 is in the locked state, it is located in the third position within the mounting cavity 12. When the water tank assembly 3 is in the unlocked state, it is located in the fourth position within the mounting cavity 12. The guide slide 320 includes: a first guide surface 322; a second guide surface 324, which is set at a first angle to the first guide surface 322; a limiting groove 327, which is surrounded by the first guide surface 322 and the second guide surface 324; and a first slide 326, with the first guide surface 322 disposed at the second end of the first slide 326. The first slide 326 is used to guide the sliding member 24 from the first end of the first slide 326 to the first guide surface 322 during the process of the water tank assembly 3 sliding from the mounting port 14 into the mounting cavity 12 to the fifth position. When the water tank assembly 3 is in the fifth position... When the water tank assembly 3 is released, it moves to the third position outside the mounting cavity 12 under the action of the elastic member 4. The sliding member 24 slides along the first guide surface 322 to the connection between the first guide surface 322 and the second guide surface 324, and is limited to the connection between the first guide surface 322 and the second guide surface 324. The second slide 328 has one end connected to the end of the second guide surface 324 away from the first guide surface 322. When the water tank assembly 3 is in the third position inside the mounting cavity 12, the water tank assembly 3 is pressed into the mounting cavity 12, and the sliding member 24 can move along the second guide surface 324 into the second slide 328. During the process of the water tank assembly 3 sliding out of the mounting cavity 12 from the mounting port 14, the sliding member 24 can move along the second slide 328.

[0167] In these embodiments, the first guide surface 322 and the second guide surface 324 can be connected to form a limiting groove 327. After the water tank assembly 3 is installed in place, the sliding member 24 is limited within the limiting groove 327 by the rebound force of the elastic member 4. Thus, through the interaction between the limiting groove 327 and the sliding member 24, the position of the water tank assembly 3 can be limited, preventing the water tank assembly 3 from falling out of the mounting cavity 12 without other external forces. In order to guide the sliding member 24 to enter the limiting groove 327 formed by the first guide surface 322 and the second guide surface 324 normally, a first slide rail 326 is provided. Through the first slide rail 326, the sliding member 24 can be guided to move along a preset trajectory. This ensures that after the water tank assembly 3 is installed in place, the sliding member 24 can just reach the bottom of the limiting groove 327, and the sliding member 24 will not be stuck in advance, which would prevent the water tank assembly 3 from being installed correctly.

[0168] When it is necessary to disassemble the water tank assembly 3, the water tank assembly 3 can be pressed into the mounting housing 1 so that the other end of the sliding member 24 can move along the second guide surface 324 to separate from the limiting groove 327, thereby releasing the locking of the mounting housing 1 to the water tank assembly 3, so that the water tank assembly 3 can be pulled out from the mounting housing 1, thereby realizing the disassembly of the water tank assembly 3 relative to the mounting housing 1.

[0169] As shown in Figure 3 The guide slide 320 further comprises a second slide 328. When the water tank assembly 3 is pulled out of the installation housing 1, the sliding member 24 can slide along the second slide 328, so as to limit the position of the sliding member 24 and guide the water tank assembly 3, avoiding the water tank assembly 3 from being offset and stuck with the installation housing 1.

[0170] In addition, when the water tank assembly 3 is inserted into the installation housing 1 and pulled out of the installation housing 1, the movement path of the sliding member 24 is inconsistent and forms a loop, so that the locking and unlocking cooperation between the sliding member 24 and the guide slide 320 is more reliable.

[0171] Conversely, the second slide 328 can not be provided, and the structures of the first slide 326 and the first guide surface 322 are reasonably arranged, so that the other end of the sliding member 24 can return to the first slide 326 along the first guide surface 322 when the water tank assembly 3 is unlocked.

[0172] In any of the above embodiments, optionally, as shown in Figure 3 The guide slide 320 further comprises an expanded section 329 arranged at the first end of the first slide 326, and fourth guide surfaces 3292 are arranged on the inner side walls of the expanded section 329, and the fourth guide surfaces 3292 are used to guide the sliding member 24 to move into the first slide 326 during the sliding of the water tank assembly 3 into the installation cavity 12 from the installation opening 14.

[0173] In these embodiments, since the sliding member 24 has a certain sliding range, after the water tank assembly 3 is removed, the position of the sliding member 24 is not fixed. After the water tank assembly 3 is correctly inserted into the installation housing 1, the sliding member 24 can always fall within the range of the expanded section 329, and when the water tank assembly 3 is inserted inward, the sliding member 24 can be guided into the first slide 326 through the fourth guide surface. This structure makes the sliding member 24 be able to slide into the first slide 326 regardless of the initial position, and then move along the fixed track to the limiting portion. In this way, before the water tank assembly 3 is installed, the sliding member 24 does not need to be reset, and the position of the sliding member 24 does not need to be determined intentionally, so that the installation of the water tank assembly 3 is more convenient.

[0174] Of course, in other schemes, the expanded section 329 and the fourth guide surface 3292 can not be provided, and in this case, in order to ensure that the sliding member 24 can slide into the first slide 326, the position of the sliding member 24 needs to be fixed in advance.

[0175] In any of the above embodiments, optionally, as shown in Figure 1As shown, the mounting shell 1 is provided with a limiting hole 10, and the sliding member 24 is slidingly mounted in the limiting hole 10, and the sliding range of the sliding member 24 can be limited by the limiting hole 10.

[0176] In the embodiments, in order to avoid the sliding member 24 from sliding excessively, the mounting shell 1 is provided with a limiting hole 10, and the sliding range of the sliding member 24 can be limited by the limiting hole 10, so that the sliding member 24 can only move in a predetermined area, thereby limiting the position of the sliding member 24, avoiding the situation that the sliding member 24 cannot cooperate with the second limiting member 32 on the water tank assembly 3, and thus ensuring that the sliding member 24 can always cooperate with the second limiting member 32 to lock the water tank assembly 3 after the water tank assembly 3 is mounted on the water tank shell 30.

[0177] In any of the above embodiments, optionally, as shown, Figure 1 The movable member 22 comprises a rotating member 26, a first end of the rotating member 26 is rotatably mounted outside the mounting shell 1, the mounting shell 1 is provided with a limiting hole 10, a second end of the rotating member 26 penetrates through the limiting hole 10 and is inserted into the mounting cavity 12, and the sliding member 24 is arranged on the second end of the rotating member 26. The sliding member 24 and the rotating member 26 are in an integrated structure, or the sliding member 24 is detachably connected with the rotating member 26.

[0178] In the embodiments, the movable member 22 comprises the rotating member 26, and the sliding member 24 is arranged on the rotating member 26. The rotation of the rotating member 26 can drive the sliding member 24 to slide. This structure can conveniently realize the sliding installation of the sliding member 24.

[0179] The sliding member 24 and the rotating member 26 can form one part, for example, the two are integrally formed or are respectively machined and then connected into an integrated structure. In addition, the sliding member 24 and the rotating member 26 can also be two completely independent parts.

[0180] In any of the above embodiments, optionally, as shown, Figure 1 The water tank device 100 further comprises a pressing member 5 arranged outside the mounting shell 1, and at least a part of the rotating member 26 is located between the pressing member 5 and the mounting shell 1.

[0181] In the embodiments, the pressing member 5 is used to press the rotating member 26 towards the water tank assembly 3, so as to limit the position of the rotating member 26, so that the rotating member 26 can abut against the water tank assembly 3, and the situation that the rotating member 26 and the water tank assembly 3 are separated from each other during rotation is avoided.

[0182] In any of the above embodiments, optionally, the pressing member 5 is elastic, and can press the rotating member 26 towards the water tank assembly 3 by elasticity.

[0183] In these embodiments, the press-fitting member 5 can be configured as an elastic structure, so that the elastic force of the press-fitting member 5 can press the rotating member 26, so that the other end of the rotating member 26 can always abut against the water tank assembly 3, avoiding the situation where the other end of the rotating member 26 separates from the water tank assembly 3 and the water tank assembly 3 cannot be locked.

[0184] In any of the above embodiments, optionally, as Figure 1 As shown, the water tank device 100 also includes a support structure 18, which is disposed on the outer wall of the mounting housing 1 and supported on the side of the rotating member 26 near the mounting housing 1.

[0185] In this embodiment, in order to limit the height position of the rotating component 26, a support structure 18 is provided on the mounting housing 1 to support the rotating component 26. The support structure 18 can better limit the installation height of the rotating component 26. At the same time, the support structure 18 can also reduce the contact area between the rotating component 26 and the mounting housing 1, thereby reducing the friction between the rotating component 26 and the mounting housing 1.

[0186] like Figure 7 As shown, an embodiment of the second aspect of the present invention provides a steam cooking appliance 200, including: a water tank device 100 provided in any embodiment of the first aspect.

[0187] The steam cooking appliance 200 provided according to the embodiments of the present invention includes the water tank device 100 provided in any embodiment of the first aspect. Therefore, the steam cooking appliance 200 has all the beneficial effects of the water tank device 100 provided in any embodiment of the first aspect, which will not be repeated here.

[0188] In any of the above embodiments, optionally, as Figure 7 and Figure 8 As shown, the steam cooking appliance 200 includes a housing 6 and a door 7.

Wherein, the water tank assembly 3 is installed on the side of the box body 6 provided with the door body 7, for example, the water tank assembly 3 is arranged on the front side of the box body 6. Meanwhile, the water tank assembly 3 can also be installed on the box body 6 along the front side of the box body 6, and the water tank assembly 3 can be pulled out in the front-rear direction to realize the disassembly and assembly of the water tank assembly 3. Meanwhile, the water tank assembly 3 is also placed in front of and behind the box body 6, that is, the water tank assembly 3 is installed on the box body 6 in the transverse direction, not in the vertical direction.

[0190] Further, as shown in the figure, Figures 1 to 8 The water tank assembly 3 can be installed on the box body 6 along the first direction by the installation opening 14.

Meanwhile, in order to ensure the sealing between the water tank shell 30 and the cover 302, a sealing ring is arranged between the two, and the two are connected in a sealed manner through the sealing ring, so that the water tank assembly 3 can be prevented from leaking.

[0192] In the related scheme, the water tank assembly arranged on the oven is directly provided with a water filling port on the side wall of the water tank shell, without a detachable cover, so that the interior of the water tank cannot be opened, and it is very inconvenient to clean the interior of the water tank. In the present application, the detachable cover body 302 is specially arranged, so that when the water tank assembly 3 needs to be cleaned, the cover body 302 can be opened to clean the interior of the water tank shell 30, thereby improving the cleaning convenience of the water tank assembly 3 and ensuring the cleanliness of the water tank assembly 3. At the same time, since the user can open the cover body 302 to view the interior of the water tank shell 30, the user can conveniently check the dirt condition in the interior of the water tank assembly 3 in time, so that the user can discover the dirt in the water tank assembly 3 more quickly, thereby facilitating the user to clean the water tank assembly 3 in time, so that the user can use the water tank assembly 3 more confidently.

[0196] In any of the above embodiments, optionally, as shown in Figure 7 and Figure 8 The steam cooking appliance 200 further comprises a heating device mounted on the box body 6 and configured to heat food materials in the cooking cavity 62; a water receiving groove 9 mounted in the cooking cavity 62 and capable of being heated by the heating device; and a connecting pipe group 8 configured to connect the water tank device 100 and the water receiving groove 9, so as to convey water in the water tank device 100 to the water receiving groove 9.

[0197] Further, the water in the water tank device 100 can flow to the water receiving groove 9 through the connecting pipe group 8 under the action of gravity.

[0198] In the above embodiments, optionally, as shown in Figure 2As shown, the water tank shell 30 comprises a first arc surface arranged along the circumferential direction of the water tank shell 30, and the two ends of the first arc surface along the circumferential direction of the water tank shell 30 are connected by a first outer side wall surface, the first outer side wall surface comprises a first plane 304 and a second arc surface, the first plane 304 is provided with an indication structure 306 to indicate the installation direction of the water tank assembly 3, and the second arc surface is located on the side of the first plane 304 close to the water inlet / outlet 342 of the water tank shell 30.

[0199] In this embodiment, the water tank shell 30 is generally cylindrical in structure, and most of the outer wall surface thereof is arc-shaped, such as a circular arc. However, at least part of the outer wall surface of the water tank shell 30 is a first plane 304. The first plane 304 is provided to facilitate the installation of the indication structure 306 and the first limiting member of the water tank assembly 3. For example, during processing, a cylindrical water tank can be first processed, and then part of the outer wall surface of the cylindrical water tank is flattened to form the first plane 304.

[0200] In addition, by providing the first plane 304, the user can also distinguish the front and back of the water tank shell 30, thereby avoiding incorrect installation of the water tank assembly 3.

[0201] Further, the first outer side wall surface further comprises a second arc surface, and the second arc surface is located on the side of the first plane 304 close to the water inlet / outlet 342 of the water tank shell 30, that is, the part of the first outer wall surface close to the water inlet / outlet 342 is arc-shaped rather than planar. In this way, the outer wall surface around the entire water inlet / outlet 342 is circular, thereby facilitating the circular arrangement of the cover body 302. In this way, the overall appearance of the water tank assembly 3 can be more aesthetically pleasing, especially when the water tank assembly 3 is used in an oven or the like. The shape of the water tank assembly 3 can be consistent with that of the knob or the like on the oven, thereby improving the overall aesthetic appeal of the oven.

[0202] In the above embodiment, optionally, as Figure 2 shown, the water tank shell 30 comprises two oppositely arranged second outer side wall surfaces, and each of the second outer side wall surfaces is provided with one of a guide rib 308 and a guide groove, and the guide rib 308 or the guide groove is arranged along the first direction. The water tank assembly 3 can be slidably installed on the installation shell 1 through the guide of the guide rib 308 and the guide groove.

[0203] In this embodiment, the outer wall surfaces of the two oppositely arranged sides of the water tank shell 30 are provided with guide structures, such as guide ribs 308 or guide grooves. Meanwhile, the cooking cabinet can be provided with another guide structure that is adapted thereto. In this way, the water tank assembly 3 can be more smoothly installed on the cooking cabinet through the cooperation of the two guide structures, thereby facilitating the disassembly and assembly of the water tank assembly 3 on the cooking cabinet. Meanwhile, the guide rib 308 or the guide groove is arranged along the first direction, thereby enabling the water tank assembly 3 to be slidably installed on the cooking cabinet along the first direction.

[0204] The water tank device 100 is located at the top of the cooking cavity 62 along the height direction of the box body 6, so that the water tank device 100 is installed higher, thereby providing conditions for the water tank device 100 to drain water by gravity.

[0205] In any of the above embodiments, optionally, the box body 6 comprises an inner container 60, the inner container 60 surrounds the cooking cavity 62, and the water tank device 100 is installed above the inner container 60. This arrangement makes the water tank device 100 installed higher, thereby facilitating the water tank assembly to drain water by gravity. In addition, this arrangement can reasonably utilize the height space of the product, so as to reduce the width of the product and reduce the floor area occupied by the product, thereby facilitating the storage of the product.

[0206] Optionally, the box body 6 comprises a first part and a second part, the door body 7 is installed on the first part, the second part is located above the first part along the height direction of the box body 6, and the water tank device 100 is installed on the second part. In this way, the water tank assembly can be exposed to the door body 7, so that the door body 7 does not need to be opened when water is added, thereby facilitating water addition during cooking.

[0207] The water tank device and the steam cooking appliance in the present application will be further introduced below by taking an oven as an example.
