TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a water tank device and a steam cooking appliance. BACKGROUND

[0002] The oven with a steam function in the related scheme is provided with a water tank assembly capable of being telescoped, wherein the telescoping mode of the water tank assembly has two schemes, the first one is to realize the telescoping of the water tank by controlling the motor, and the second one is to realize the telescoping of the water tank by manually pressing through the setting of a rebound device. The above two structures need to additionally set the rebound device or the motor, so that the structure of the system is relatively complex, thereby increasing the cost of the product.

[0003] Therefore, how to design a telescopic water tank assembly and a steam oven with simple structure and low cost has become a problem to be solved at present. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at least to solve the problems of complex structure and high cost of the steam oven in the prior art or related art.

[0005] The first purpose of the utility model is to provide a water tank device.

[0006] The second purpose of the utility model is to provide a steam cooking appliance.

[0007] The embodiment of the first aspect of the utility model provides a water tank device, which comprises: a mounting shell comprising a mounting cavity, the mounting cavity being provided with a mounting opening at one end; a first limiting piece mounted on the mounting shell; a water tank assembly capable of being slid into a first position in the mounting cavity or out of the mounting cavity through the mounting opening, the water tank assembly comprising a second limiting piece; an elastic piece mounted between the water tank assembly and the mounting shell, the first limiting piece and the second limiting piece being mutually buckled to lock the water tank assembly when the water tank assembly is located at the first position in the mounting cavity, and the elastic piece being in a compressed state; when the water tank assembly is located at the first position, pressing the water tank assembly into the mounting cavity can release the limiting between the first limiting piece and the second limiting piece to unlock the water tank assembly and make the elastic piece elongate, and the elongation of the elastic piece can push the water tank assembly to move to a second position, in which a part of the water tank assembly extends out of the mounting opening.

[0008] The water tank device according to the embodiments of the utility model can be specifically used in a steam cooking utensil, and the steam cooking utensil can be an oven or the like. The water tank device specifically comprises a mounting shell and a water tank assembly. The water tank assembly can be pressed into the mounting shell or ejected from the mounting shell. The water tank assembly and the mounting shell can be locked and unlocked through the first limiting structure and the second limiting piece. After the water tank assembly is unlocked, the water tank assembly can be taken out of the mounting shell to add water, clean or replace the water tank assembly. 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 prone to shaking, so that the water tank assembly is not prone to sliding out of the mounting shell.

[0009] The structure can push the water tank assembly into the mounting shell when the water tank assembly is installed, and the water tank assembly can be ejected from the mounting shell by pressing the water tank assembly when the water tank assembly needs to be taken out. The water tank assembly can be separately detached from the product for water adding or cleaning. The water tank assembly does not need to be detached with the aid of a motor or other power equipment, 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 piece is arranged on the water tank assembly, so that the elastic piece can directly act on the water tank assembly, the water tank assembly can be directly limited through the first limiting structure, the water tank assembly is more reliable in limiting, and the water tank assembly is more stable in the mounting shell, so that the water tank assembly is not prone to loosening.

[0010] In addition, the structure for driving the water tank assembly to rebound is directly integrated on the water tank assembly and the mounting shell, so that the structure of the water tank device is relatively simple, and the cost of the product can be reduced. In addition, the water tank assembly itself serves as a rebounding piece, so that the pressing and ejection of the water tank assembly are more reliable.

[0011] In any of the above technical solutions, the water tank assembly comprises a water tank shell, and the second limiting piece is arranged on the water tank shell.

[0012] 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 piece is used for limiting the position of the water tank assembly in the mounting shell.

[0013] In any of the above technical solutions, the second limiting piece and the water tank shell are in an integral structure.

[0014] In the technical solutions, the second limiting member can be 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 integrated structure, so that the connection strength of the two is higher, and the reliability is better. Of course, in other solutions, the second limiting member and the water tank shell can be arranged separately, and then the second limiting member is detachably mounted on the water tank shell.

[0015] 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 mounted on the mounting shell, and a part of the movable member is located in the guide slide; when the water tank assembly is installed to the first position in the mounting cavity, at least a part of the movable member can be moved to the limiting slot from the first end of the guide slide and be limited in the limiting slot; when the water tank assembly is located at the first position, the water tank assembly is pressed into the mounting cavity, and the movable member can be moved along the guide slide to be separated from the limiting slot, so as to unlock the water tank assembly and make the elastic member elongate.

[0016] 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 relatively move in the guide slide. A limiting slot is arranged in the guide slide, and the movable member can be limited by the limiting slot, so as to ensure that the water tank assembly can be locked and installed at the first position. Then, when the water tank assembly needs to be detached, the water tank assembly can be pressed into the mounting shell, so that the water tank assembly moves inward, and the movable member can be moved to a position separated from the limiting slot again, so that the movable member limits the water tank assembly, and the water tank assembly is in an unlocked state. After the water tank assembly is unlocked, the elastic member can rebound, so as to push the water tank assembly to move a distance out of the mounting shell. In this way, the water tank can be automatically popped out, which is convenient for the user to subsequently detach the water tank assembly for cleaning, water adding or maintenance.

[0017] In any of the above technical solutions, optionally, when the water tank assembly is located at the first position, the water tank assembly is pressed into the mounting cavity, and at least a part of the movable member can move to the second end of the guide slide and be separated from the limiting slot.

[0018] In the technical solutions, when the water tank assembly is pulled out of the mounting shell, the movable member can continue to slide as before, instead of sliding back. In this way, when the water tank assembly is inserted into the mounting shell and pulled out of the mounting shell, the movement path of the movable member is inconsistent, so that the locking and unlocking cooperation between the movable member and the guide slide is more reliable.

[0019] 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.

[0020] In any of the above technical solutions, optionally, the movable member comprises a sliding member, the sliding member being capable of sliding along the guide slide and being capable of being limited in the limiting groove when the water tank assembly is located at the first position.

[0021] In the above technical solutions, the movable member comprises a sliding member. The insertion and removal of the water tank assembly can be realized through the sliding of the sliding member along the guide slide. When the water tank assembly is inserted and installed in place, i.e., the water tank assembly is installed at the first position, the sliding member can be better clamped in the limiting groove, so that the sliding of the sliding member can be prevented by the limiting groove, thereby 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 and the sliding member slides out of the limiting groove along the second guide surface, thereby the limiting fit between the sliding member and the limiting groove can be released, so that the water tank assembly is in a free state, thereby the water tank assembly can be conveniently removed for heating, water adding, cleaning or maintenance and replacement.

[0022] In any of the above technical solutions, optionally, the guide slide comprises a first guide surface, a second guide surface arranged at a first angle with the first guide surface, the limiting groove being surrounded by the first guide surface and the second guide surface, a first slide, the first guide surface being arranged at a second end of the first slide, the first slide being used for guiding the sliding member to move from a first end of the first slide to the first guide surface during the process that the water tank assembly slides from the installation opening into the installation cavity to the third position, when the water tank assembly is located at the third position, the water tank assembly is loosened, the water tank assembly moves to the first position outside the installation cavity under the action of the elastic member, the sliding member slides along the first guide surface to a 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, when the water tank assembly is located at the first position, the water tank assembly is pressed into the installation cavity, the sliding member can move along the second guide surface to separate from the limiting groove.

[0023] In the above 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 member is limited in the limiting groove under the resilience of the elastic member, thereby the position of the water tank assembly can be limited by the interaction between the limiting groove and the sliding member, so that the water tank assembly cannot fall from the installation cavity without other external force. In order to guide the sliding member 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 member can be guided to move along a preset track, so that when the water tank assembly is installed in place, the sliding member can just reach the bottom of the limiting groove, and the situation that the sliding member is stuck in advance and the water tank assembly cannot be correctly installed can be avoided.

[0024] 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 separate 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.

[0025] In any of the above technical solutions, optionally, the guide slide further comprises a second slide, one end of the second slide is connected with the other end of the second guide surface away from the first guide surface, when the water tank assembly is in the first position, the water tank assembly is pressed into the mounting cavity, and the sliding piece can move along the second guide surface into the second slide; during the process that the water tank assembly slides out of the mounting cavity through the mounting opening, the sliding piece can move along the second slide.

[0026] In the technical solutions, the guide 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, so as to define the position of the sliding piece, and at the same time, the water tank assembly can be guided to avoid the water tank assembly from being offset and stuck with the mounting shell.

[0027] 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, so that the locking and unlocking cooperation between the sliding piece and the guide slide is more reliable.

[0028] 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 move along the first guide surface back into the first slide.

[0029] In any of the above technical solutions, optionally, the guide slide further comprises an outwardly extending section arranged at the first end of the first slide, fourth guide surfaces are arranged on the two inner side walls of the outwardly extending section, and the fourth guide surfaces are used to guide the sliding piece to move into the first slide during the process that the water tank assembly slides into the mounting cavity through the mounting opening.

[0030] In the technical solutions, since the sliding piece has a certain sliding range, after the water tank assembly is removed, the position of the sliding piece is not fixed. After the water tank assembly is correctly inserted into the mounting shell, the sliding piece can always fall within the range of the outwardly extending section, and when the water tank assembly is inserted inwardly, the sliding piece can be guided into the first slide through 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, so that the installation of the water tank assembly is more convenient.

[0031] Of course, in other solutions, the outer expansion section and the fourth guide surface can not be provided, and in this case, in order to ensure that the sliding member can slide into the first sliding channel, the position of the sliding member needs to be fixed in advance.

[0032] In any of the above embodiments, optionally, a limiting hole is arranged on the mounting shell, and the sliding member is slidingly installed in the limiting hole, and the sliding range of the sliding member can be limited through the limiting hole.

[0033] In these technical solutions, in order to avoid the sliding member from sliding excessively, a limiting hole is arranged on the mounting shell, and the sliding range of the sliding member can be limited through the limiting hole, 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 moves to other positions and cannot cooperate with the second limiting member on the water tank assembly, so as to ensure that after the water tank assembly is installed on the water tank shell, the sliding member can always cooperate with the second limiting member to lock the water tank assembly.

[0034] In any of the above technical solutions, optionally, the movable member comprises a rotating member, a first end of the rotating member is rotatably installed outside the mounting shell, a limiting hole is arranged on the mounting shell, a second end of the rotating member penetrates through the limiting hole and is inserted into the mounting cavity, the sliding member is arranged on the second end of the rotating member, the sliding member and the rotating member are an integral structure, or the sliding member and the rotating member are detachably connected.

[0035] In these technical solutions, the movable member comprises a rotating member, and the sliding member is arranged on the rotating member. The rotation of the rotating member can drive the sliding member to slide. This structure can conveniently realize the sliding installation of the sliding member.

[0036] The sliding member and the rotating member can form one part, for example, they can be integrally formed or 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.

[0037] In any of the above technical solutions, optionally, the water tank device further comprises a pressing member arranged outside the mounting shell, and at least part of the rotating member is located between the pressing member and the mounting shell.

[0038] In these 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 through 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 rotation.

[0039] 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.

[0040] In the technical solutions, the pressing part is arranged in an elastic structure, so that the elastic force of the pressing part can press the rotating part, and the other end of the rotating part can always abut against the water tank assembly, thereby avoiding the separation of the other end of the rotating part from the water tank assembly and the failure of locking the water tank assembly.

[0041] In any of the above embodiments, optionally, the water tank device further comprises a supporting structure arranged on the outer wall of the mounting shell and supporting the rotating part on the side close to the mounting shell.

[0042] In the embodiment, in order to limit the height position of the rotating part, the supporting structure is arranged on the mounting shell to support the rotating part, so that the installation height of the rotating part can be better limited. Meanwhile, the supporting structure can also reduce the contact area between the rotating part and the mounting shell, so as to reduce the friction therebetween.

[0043] 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 first position, so as to open the water outlet channel. After the water tank assembly slides out of the mounting cavity, the valve assembly returns to the position for closing the water outlet channel, so that the water outlet channel is closed.

[0044] 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. The valve assembly is arranged in the water outlet channel, and the valve assembly can be used for opening and closing the water outlet channel. For example, when the water tank assembly is detached from the cooking box body and water is added, the valve assembly can be used for closing the water outlet channel, so as 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, so as to facilitate the output of water from the water tank assembly.

[0045] In any of the above technical solutions, optionally, the valve assembly comprises a valve rod slidably installed in the water outlet channel, the valve rod being capable of moving between the fourth position and the fifth position under the action of the push rod; an elastic member located in the water outlet channel, one end of the elastic member being connected with the valve rod and the other end of the elastic member being connected with the inner wall of the water outlet channel; and a sealing member installed on the valve rod and capable of moving with the valve rod to open or seal the water outlet channel.

[0046] 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 at 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 moving the sealing member. The elastic member, usually a spring, is installed between the valve rod and the water tank shell. In the normal state, the elastic member is in a compressed state, and the elastic member can compress the sealing member by the elastic force of the elastic member, so that the sealing member can close 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. At the same time, the elastic member is compressed in this process, so that 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 closes the water outlet channel again.

[0047] Specifically, a push rod can be arranged on the cooking box body at a position corresponding to the water outlet channel. After the water tank assembly is installed on the cooking box body, the push rod can be inserted into the water outlet channel to push the valve rod to move along the water outlet channel, so that the water outlet channel is opened. After the water tank assembly is removed, the external force of the push rod on the valve rod disappears, and the valve rod and the sealing member return to the original position under the elastic force of the elastic member, so that the water outlet channel of the water tank assembly is closed and cannot discharge water.

[0048] Specifically, one end of the valve rod penetrates the inlet of the water outlet channel into the water cavity, and the sealing member is sealingly installed at the inlet of the water outlet channel. Along the water outlet channel, the valve rod is pushed to drive the sealing member to move away from the outlet of the water outlet channel to open the inlet of the water outlet channel. In this arrangement, the sealing member is arranged at the inlet of the water outlet channel, so that the opening and closing of the entire water outlet channel can be realized by opening and closing the inlet of the water outlet channel through the sealing member.

[0049] In this embodiment, 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 elastic member is shared by the pop-out structure of the water tank assembly and the opening and closing structure of the water outlet of the water tank assembly, so that the structure of the product can be simplified.

[0050] 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.

[0051] In any of the above technical solutions, optionally, the water outlet channel comprises a water outlet and a water inlet, the sealing member blocks the water outlet when the valve rod is in the fourth position, and the sealing member opens the water outlet when the valve rod is in the fifth position, so that the water inlet and the water outlet are communicated.

[0052] In the technical solutions, the sealing member is arranged in the water outlet channel and close to the water outlet. When the water tank assembly is not installed in the installation shell, the valve rod is in the fourth position, the sealing member blocks the water outlet, and water in the water tank shell cannot leak out through the water outlet channel. When the water tank assembly is installed in the installation shell, the push rod is inserted into the water outlet channel and pushes up the valve rod, so that the valve rod is in the fifth position, the elastic member is in a compressed state, the sealing member and the valve rod move to the other side of the water inlet together, so that the water outlet and the water inlet are communicated, and thus water in the water tank shell can be discharged through the water outlet channel to facilitate water supply for the steam cooking appliance. When the water tank assembly needs to be removed, the limiting between the water tank assembly and the shell assembly is released, the valve rod rebounds under the action of the elastic member, and the entire water tank assembly is ejected. In this structure, when the water tank assembly is ejected, 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 that too much water remains in the water outlet channel, so that when the water tank assembly is removed, water leakage of the water tank assembly can be avoided, and user experience is affected.

[0053] Conversely, the sealing member can also be arranged at the water inlet. When the water tank assembly is not installed in the installation shell, the sealing member seals the water inlet. When the water tank assembly is installed in the installation shell, the push rod pushes the valve rod to move forward, the sealing member extends out of the water outlet channel, thereby opening the inlet of the water outlet channel, and water in the water tank assembly can be discharged. Due to the length of the water outlet channel and the general horizontal placement of the water outlet channel, when the water tank assembly is unlocked, there will be some residual water in the water outlet channel. At this time, during the process of removing the water tank assembly, the water in the water outlet channel will fall down, thereby reducing the user experience.

[0054] Further, the water outlet channel can be slightly inclined downward from the inlet to the outlet, which can also reduce the residual water in the water outlet channel.

[0055] In any of the above technical solutions, optionally, the elastic member includes a spring capable of elongation or shortening.

[0056] In the technical solutions, the spring capable of elongation or shortening can better provide elastic force to eject the water tank assembly when it is necessary to detach the water tank assembly from the steam cooking appliance. At the same time, the spring can also make the valve body assembly return to the initial installation position to block the water outlet channel, thereby avoiding water leakage of the water tank assembly after it is detached from the steam cooking appliance.

[0057] Of course, the elastic member can also be a metal spring, a rubber member or other structures with certain elasticity and hardness.

[0058] The second aspect of the embodiments of the utility model provides a steam cooking appliance, comprising: the water tank device provided by any one of the first aspect.

[0059] The steam cooking utensil according to the embodiments of the present application has all the beneficial effects of the water tank device according to any one of the embodiments of the first aspect, and details are not repeated here.

[0061] The steam cooking utensil according to the embodiments of the present application comprises a cooking cabinet and a water tank assembly. The cooking cabinet can generate steam and complete cooking functions. The water tank assembly is detachably mounted on the cooking cabinet to provide water for the cooking cabinet. The cooking cabinet comprises a cabinet and a door body, and a cooking cavity is arranged in the cabinet and communicates with a food material inlet and outlet. The door body is mounted on the cabinet to open and close the food material inlet and outlet. The water tank assembly is mounted on the side of the cabinet where the door body is arranged, for example, the water tank assembly is arranged on the front side of the cabinet. At the same time, the water tank assembly can also be mounted on the cabinet along the front side of the cabinet, and the water tank assembly can be pulled out in the front-rear direction to realize the disassembly and assembly of the water tank assembly. At the same time, the water tank assembly is also placed in front of and behind the cabinet, that is, the water tank assembly is horizontally mounted on the cabinet, not vertically mounted.

[0062] Further, the water tank assembly can be mounted on the cabinet by the mounting opening along the first direction. The water tank assembly comprises a water tank housing, the water tank housing comprising a water containing cavity and a water inlet and outlet port communicating with the water containing cavity, the water inlet and outlet port being arranged at one end of the water tank housing along the first direction; a cover body being detachably mounted on the water tank housing to open or close the water inlet and outlet port; and a sealing ring being arranged between the water tank housing and the cover body to seal the gap between the water tank housing and the cover body.

[0063] In this embodiment, the water tank assembly specifically comprises a water tank housing and a cover body, the water tank housing being provided with a water inlet and outlet port, and the cover body being detachably mounted on the water inlet and outlet port of the water tank housing. At the same time, in order to ensure the sealing between the water tank housing and the cover body, a sealing ring is further arranged therebetween, and the sealing ring can be used to seal the connection between the two, so as to avoid water leakage of the water tank assembly.

[0064] In the related scheme, the water tank assembly arranged on the oven is directly provided with a water inlet 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, a detachable cover is specially arranged, so that when the water tank assembly needs to be cleaned, the cover can be opened to clean the interior 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 to view the interior of the water tank shell, the user can conveniently check the dirt condition in the interior of the water tank assembly in a timely manner, so that the user can discover the dirt in the water tank assembly more quickly, thereby facilitating the user to clean the water tank assembly in a timely manner, so that the user can use the water tank assembly more confidently.

[0068] Further, the water in the water tank device can flow to the water receiving groove through the connecting pipe group under the action of gravity.

[0069] In the above embodiment, optionally, the water tank shell comprises a first arc-shaped surface arranged along the circumferential direction of the water tank shell, two ends of the first arc-shaped surface arranged along the circumferential direction of the water tank shell are connected by a first outer side wall surface, the first outer side wall surface comprises a first plane and a second arc-shaped surface, the first plane is provided with an indication structure to indicate the mounting direction of the water tank assembly, and the second arc-shaped surface is located on the side of the first plane close to the water inlet / outlet of the water tank shell.

[0070] In this embodiment, the water tank shell is substantially 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 is a first plane, which facilitates the installation of the indication structure and the first limiting structure of the water tank assembly.

DETAILED DESCRIPTION

[0089] In order to enable the above object, features and advantages of the utility model to be more clearly understood, the utility model will be further described below 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.

[0090] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, the present application can be practiced according to other embodiments that are not specifically described herein, and the present application is not limited to the specific embodiments described herein.

[0091] The embodiments of the present application will be described below with reference to Figures 1 to 10 The water tank device 100 and the steam cooking appliance 200 provided by the embodiments of the present application will be described below.

[0092] As shown in Figure 1 , Figure 2 and Figure 3 , the embodiments of the first aspect of the present application provide a water tank device 100, comprising: a mounting shell 1, comprising a mounting cavity 12, one end of the mounting cavity 12 being provided with a mounting opening 14; a water tank assembly 3, the water tank assembly 3 being capable of sliding into a first position in the mounting cavity 12 from the mounting opening 14 or sliding out of the mounting cavity 12.

[0093] Further, as shown in Figure 1 , Figure 2 and Figure 3 , the water tank device 100 further comprises: a first limiting piece 2, mounted to the mounting shell 1. The water tank assembly 3 comprises a second limiting piece 32; an elastic piece 4, mounted between the water tank assembly 3 and the mounting shell 1, when the water tank assembly 3 is in the first position in the mounting cavity 12, the first limiting piece 2 and the second limiting piece 32 are buckled to each other to lock the water tank assembly 3, and the elastic piece 4 is in a compressed state; when the water tank assembly 3 is in the first position, pressing the water tank assembly 3 into the mounting cavity 12 can release the limiting between the first limiting piece 2 and the second limiting piece 32 to unlock the water tank assembly 3 and make the elastic piece 4 elongate, and the elongation of the elastic piece 4 can push the water tank assembly 3 to move to a second position, in which a part of the water tank assembly 3 extends out of the mounting opening 14.

[0094] The water tank device 100 provided by the embodiments of the present application can be specifically used in the steam cooking appliance 200, which can be an oven or other products. The water tank device 100 specifically comprises the mounting shell 1 and the water tank assembly 3. The water tank assembly 3 can be pressed into the mounting shell 1 or popped out of the mounting shell 1. The water tank assembly 3 and the mounting shell 1 can be locked and unlocked through the first limiting structure and the second limiting piece 32. After the water tank assembly 3 is unlocked, the water tank assembly 3 can be taken out of the mounting shell 1 to add water, clean or repair and replace the water tank assembly 3. After the water tank assembly 3 is locked, the water tank assembly 3 and the mounting shell 1 cooperate well, 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.

[0095] The structure only needs to push the water tank assembly 3 into the installation shell 1 when installing the water tank assembly 3, and when the water tank assembly 3 needs to be taken out, the water tank assembly 3 can be released from the limitation of the water tank assembly 3 under the rebound action of the elastic member 4 by pressing the water tank assembly 3, so that the water tank assembly 3 can be separately detached from the product for water filling or cleaning. The disassembly of the water tank assembly 3 does not need to rely on the power equipment such as the motor, so that the structure of the water tank device 100 can be simplified, and the cost of the water tank device 100 can be reduced. In addition, the second limiting member 32 is arranged on the water tank assembly 3, so that the elastic member 4 can directly act on the water tank assembly 3, and the water tank assembly 3 can be directly limited by the first limiting structure, so that the limitation of the water tank assembly 3 is more reliable, and the water tank assembly 3 is more stable in the installation shell 1, so that the water tank assembly 3 is not easy to loosen.

[0096] In addition, the structure for driving the water tank assembly 3 to rebound is directly integrated on the water tank assembly 3 and the installation shell 1, so that the structure of the whole water tank device 100 is relatively simple, so that the cost of the product can be reduced. In addition, the water tank assembly 3 itself serves as a rebound member, so that the pressing and rebounding of the water tank assembly 3 are more reliable.

[0097] In any of the above embodiments, optionally, the water tank assembly 3 comprises a water tank shell 30, and the second limiting member 32 is arranged on the water tank shell 30.

[0098] In the embodiments, the water tank assembly 3 comprises a water tank shell 30, and the water tank shell 30 is used for containing water. The second limiting member 32 is used for limiting the position of the water tank assembly 3 in the installation shell 1.

[0099] In any of the above embodiments, optionally, the second limiting member 32 and the water tank shell 30 are in an integral structure.

[0100] 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 integral structure, so that the connection strength is higher and the reliability is better. Of course, in other schemes, the second limiting member 32 and the water tank shell 30 can be separately arranged, and then the second limiting member 32 is detachably installed on the water tank shell 30.

[0101] In any of the above embodiments, optionally, as Figure 3As shown, the second limiting member 32 comprises a guide slide 320, and the guide slide 320 comprises a limiting groove 327; the first limiting member 2 comprises a movable member 22, and the movable member 22 is installed 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 installed in the first position in the mounting cavity 12, at least a part of the movable member 22 can be moved to the limiting groove 327 from the first end of the guide slide 320 and be limited in the limiting groove 327; when the water tank assembly 3 is in the first position, the water tank assembly 3 is pressed into the mounting cavity 12, and the movable member 22 can be moved along the guide slide 320 to be separated from the limiting groove 327, so as to unlock the water tank assembly 3 and make the elastic member 4 be elongated.

[0102] In the embodiments, the first limiting member 2 comprises the movable member 22. When the water tank assembly 3 is installed in the mounting shell 1 or is taken out from the mounting shell 1, the movable member 22 can be moved relative to the water tank assembly 3. The limiting groove 327 is arranged in the guide slide 320, 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 installed in the first position. Then, when the water tank assembly 3 needs to be disassembled, 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 be moved to a position separated 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 be 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 ejection of the water tank, and facilitate the user to disassemble the water tank assembly 3 for cleaning, water adding or maintenance.

[0103] In any of the above embodiments, optionally, as shown, when the water tank assembly 3 is in the first position, the water tank assembly 3 is pressed into the mounting cavity 12, and at least a part of the movable member 22 can be moved to the second end of the guide slide 320 and be separated from the limiting groove 327. Figure 3

[0104] In the embodiments, when the water tank assembly 3 is taken out from the mounting shell 1, the movable member 22 can continue to slide previously, instead of sliding back. In this way, when the water tank assembly 3 is inserted into the mounting shell 1 and is pulled out from 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.

[0105] Conversely, when the water tank assembly 3 is unlocked, at least a part of the movable member 22 can also move back to the first end of the guide slide 320 until the movable member 22 is separated from the limiting groove 327.

[0106] In the embodiments, the first limiting member 2 comprises the movable member 22. When the water tank assembly 3 is installed in the mounting shell 1 or is taken out from the mounting shell 1, the movable member 22 can be moved relative to the water tank assembly 3. The limiting groove 327 is arranged in the guide slide 320, 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 installed in the first position. Then, when the water tank assembly 3 needs to be disassembled, 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 be moved to a position separated 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 be 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 ejection of the water tank, and facilitate the user to disassemble the water tank assembly 3 for cleaning, water adding or maintenance. Figure 3 ​The arrow in the figure indicates the movement path of the movable part 22 when the water tank assembly 3 is being installed and unlocked.

[0107] In any of the above embodiments, optionally, as shown in Figure 1 、 Figure 2 and Figure 3 , the movable part 22 comprises a sliding part 24, which is capable of sliding along the guide slide 320 and being limited in the limiting groove 327 when the water tank assembly 3 is in the first position.

[0108] In the embodiments, the movable part 22 comprises the sliding part 24. The insertion and removal of the water tank assembly 3 can be realized by the sliding of the sliding part 24 along the guide slide 320. Meanwhile, after the water tank assembly 3 is inserted and installed in place, i.e. the water tank assembly 3 is installed to the first position, the sliding part 24 can be better clamped in the limiting groove 327, so as to prevent the sliding of the sliding part 24 through the limiting groove 327, thereby realizing the locking of the water tank assembly 3. When it is needed to remove the water tank assembly 3 again, the water tank assembly 3 can be pressed inwardly, so as to make the limiting groove 327 retreat and the sliding part 24 slide out of the limiting groove 327 along the second guide surface 324, so as to release the limiting cooperation between the sliding part 24 and the limiting groove 327, so that the water tank assembly 3 is in a free state, thereby facilitating the removal of the water tank assembly 3, and the heating and water adding, cleaning or maintenance and replacement of the water tank assembly 3.

[0109] In any of the above embodiments, optionally, as shown in Figure 3 , the guide slide 320 comprises: a first guide surface 322; a second guide surface 324, which is arranged at a first angle with the first guide surface 322, and the limiting groove 327 is surrounded by the first guide surface 322 and the second guide surface 324; a first slide 326, the first guide surface 322 is arranged at the second end of the first slide 326, and the first slide 326 is used for guiding the movement of the sliding part 24 from the first end of the first slide 326 to the first guide surface 322 in the process that the water tank assembly 3 slides from the installation opening 14 into the installation cavity 12 to the third position; when the water tank assembly 3 is in the third position, the water tank assembly 3 is loosened, and the water tank assembly 3 moves to the first position outside the installation cavity 12 under the action of the elastic member 4, the sliding part 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 at the connection between the first guide surface 322 and the second guide surface 324; when the water tank assembly 3 is in the first position, the water tank assembly 3 is pressed into the installation cavity 12, and the sliding part 24 can move along the second guide surface 324 to separate from the limiting groove 327.

[0110] In the 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 piece 24 is limited in the limiting groove 327 under the elastic recovery force of the elastic piece 4, so that the position of the water tank assembly 3 can be limited through the interaction of the limiting groove 327 and the sliding piece 24, so that the water tank assembly 3 cannot fall out of the installation cavity 12 without other external force. In order to guide the sliding piece 24 to normally enter the limiting groove 327 formed by the first guide surface 322 and the second guide surface 324, a first sliding channel 326 is arranged. Through the first sliding channel 326, the sliding piece 24 can be guided to move along a preset track, so that after the water tank assembly 3 is installed in place, the sliding piece 24 can just reach the bottom of the limiting groove 327, and the situation that the sliding piece 24 is stuck in advance and the water tank assembly 3 cannot be correctly installed does not occur.

[0111] When it is necessary to disassemble the water tank assembly 3, the water tank assembly 3 can be pressed into the installation shell 1, so that the other end of the sliding piece 24 can move along the second guide surface 324 to separate from the limiting groove 327, thereby releasing the locking of the installation shell 1 on the water tank assembly 3, so that the water tank assembly 3 can be pulled out of the installation shell 1, so as to realize the disassembly of the water tank assembly 3 relative to the installation shell 1.

[0112] In any of the above embodiments, optionally, as shown in Figure 3 The guide sliding channel 320 further includes a second sliding channel 328. When the water tank assembly 3 is pulled out of the installation shell 1, the sliding piece 24 can slide along the second sliding channel 328, so as to limit the position of the sliding piece 24, and guide the water tank assembly 3 to avoid the water tank assembly 3 from being offset and stuck in the installation shell 1.

[0113] In the embodiments, the guide sliding channel 320 further includes the second sliding channel 328. When the water tank assembly 3 is pulled out of the installation shell 1, the sliding piece 24 can slide along the second sliding channel 328, so as to limit the position of the sliding piece 24, and guide the water tank assembly 3 to avoid the water tank assembly 3 from being offset and stuck in the installation shell 1.

[0114] In addition, when the water tank assembly 3 is inserted into the installation shell 1 and pulled out of the installation shell 1, the movement path of the sliding piece 24 is inconsistent and forms a loop, so that the locking and unlocking cooperation between the sliding piece 24 and the guide sliding channel 320 is more reliable.

[0115] Conversely, the second slide 328 can not be provided, and the structure of the first slide 326 and the first guide surface 322 can be 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.

[0116] In any of the above embodiments, optionally, as shown in Figure 3 The guide slide 320 further includes an outwardly expanding 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 outwardly expanding section 329. 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 mounting cavity 12 from the mounting opening 14.

[0117] 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 mounting shell 1, the sliding member 24 can always fall within the range of the outwardly expanding section 329, and when the water tank assembly 3 is inserted inwardly, the sliding member 24 can be guided into the first slide 326 by the fourth guide surfaces. 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 a fixed trajectory 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 deliberately determined, so that the installation of the water tank assembly 3 is more convenient.

[0118] Of course, in other schemes, the outwardly expanding section 329 and the fourth guide surfaces 3292 can not be provided. At this time, 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.

[0119] In any of the above embodiments, optionally, as shown in Figure 1 The mounting shell 1 is provided with a limiting hole 10, and the sliding member 24 is slidably arranged in the limiting hole 10. The sliding range of the sliding member 24 can be limited by the limiting hole 10.

[0120] In these embodiments, in order to avoid the sliding member 24 from sliding excessively, the limiting hole 10 is arranged on the mounting shell 1, 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 within a predetermined area. In this way, the position of the sliding member 24 can be limited, and the situation that the sliding member 24 moves to other positions and cannot cooperate with the second limiting member 32 on the water tank assembly 3 can be avoided. In this way, it can be ensured that after the water tank assembly 3 is installed on the water tank shell 30, the sliding member 24 can always cooperate with the second limiting member 32 to lock the water tank assembly 3.

[0121] In any of the above embodiments, optionally, asFigure 1 As shown, 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, a limiting hole 10 is arranged on the mounting shell 1, a second end of the rotating member 26 passes through the limiting hole 10 and is inserted into the mounting cavity 12, the sliding member 24 is arranged on the second end of the rotating member 26, and the sliding member 24 and the rotating member 26 are in an integrated structure or detachably connected.

[0122] 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 sliding of the sliding member 24 can be realized by the rotation of the rotating member 26. In this structure, the sliding installation of the sliding member 24 can be realized more conveniently.

[0123] The sliding member 24 and the rotating member 26 can form one part, for example, the two are integrally formed or are respectively processed 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.

[0124] In any of the above embodiments, optionally, as shown in Figure 1 The water tank device 100 further comprises a pressing member 5 arranged outside the mounting shell 1, and at least part of the rotating member 26 is located between the pressing member 5 and the mounting shell 1.

[0125] In the embodiments, the pressing member 5 is used to press the rotating member 26 towards the water tank assembly 3, so that the position of the rotating member 26 can be limited by the pressing member 5, 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 the rotation of the rotating member 26 is avoided.

[0126] In any of the above embodiments, optionally, the pressing member 5 is elastic, and the rotating member 26 can be pressed towards the water tank assembly 3 by the elasticity of the pressing member 5.

[0127] In the embodiments, the pressing member 5 can be arranged in an elastic structure, so that the rotating member 26 can be pressed by the elastic force of the pressing member 5, so that the other end of the rotating member 26 can always abut against the water tank assembly 3, and the situation that the other end of the rotating member 26 and the water tank assembly 3 are separated from each other and the water tank assembly 3 cannot be locked is avoided.

[0128] In any of the above embodiments, optionally, as shown in Figure 1 The water tank device 100 further comprises a support structure 18 arranged on the outer wall of the mounting shell 1 and supported on the side of the rotating member 26 close to the mounting shell 1.

[0129] In the embodiment, in order to limit the height position of the rotating member 26, a supporting structure 18 is arranged on the mounting shell 1 to support the rotating member 26, through which the mounting height of the rotating member 26 can be better limited. Meanwhile, through the supporting structure 18, the contact area between the rotating member 26 and the mounting shell 1 can be reduced to reduce the friction therebetween.

[0130] In any of the above embodiments, as shown in Figure 4 、 Figure 5 、 Figure 7 and Figure 8 , the water tank assembly 3 comprises a water tank shell 30, the water tank shell 30 comprising a water outlet passage 34; a valve assembly 36 is arranged at the water outlet passage 34 to open or close the water outlet passage 34; the push rod 16 is arranged on the mounting shell 1 to be inserted into the water outlet passage and push the valve assembly 36 to move to open the water outlet passage 34 when the water tank assembly 3 is mounted at the first position, and the valve assembly 36 returns to the position to close the water outlet passage 34 to close the water outlet passage 34 after the water tank assembly 3 slides out of the mounting cavity 12.

[0131] In the embodiments, the water tank assembly 3 comprises a water tank shell 30, the water tank shell 30 comprising a water outlet passage 34, and water in the water tank assembly 3 can be discharged through the water outlet passage 34. The valve assembly 36 is arranged in the water outlet passage 34, through which the water outlet passage 34 can be opened and closed, for example, when the water tank assembly 3 is detached from the cooking box body to add water, the valve assembly 36 can be used to close the water outlet passage 34 to facilitate the addition of water to the water tank assembly 3. When the water tank assembly 3 is mounted on the cooking box body and steam needs to be generated, the water outlet passage 34 can be opened to facilitate the water output of the water tank assembly 3.

[0132] In any of the above embodiments, as shown in Figure 4 and Figure 5 , the valve assembly 36 comprises a valve rod 38 which is slidingly arranged in the water outlet passage 34 and can act between the fourth position and the fifth position under the action of the push rod 16; an elastic member 4 is arranged in the water outlet passage 34, one end of the elastic member 4 is connected with the valve rod 38, and the other end of the elastic member 4 is connected with the inner wall of the water outlet passage 34; a sealing member 39 is arranged on the valve rod 38 and can move with the valve rod 38 to open or seal the water outlet passage 34.

[0133] In this embodiment, the valve assembly 36 specifically comprises a valve rod 38, a resilient member 4 and a sealing member 39. The valve rod 38 is slidably installed in the water outlet passage 34, and the sealing member 39 is installed at one end of the valve rod 38 and can move with the valve rod 38, so that the water outlet passage 34 can be opened or closed by moving the sealing member 39. The resilient member 4 is generally a spring. The resilient member 4 is installed between the valve rod 38 and the water tank shell 30, and in the normal state, the resilient member 4 is in a compressed state, and the resilient member 4 can compress the sealing member 39 by the elastic force of the resilient member 4, so that the sealing member 39 can close the water outlet passage 34. When the valve rod 38 is pushed along the water outlet passage 34, the valve rod 38 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 rod 38 disappears, the resilient member 4 can drive the valve rod 38 to return to the initial position, so that the sealing member 39 closes the water outlet passage 34 again.

[0134] Specifically, a push rod 16 can be arranged on the cooking box body at a position corresponding to the water outlet passage 34. After the water tank assembly 3 is installed on the cooking box body, the push rod 16 can be inserted into the water outlet passage 34 to push the valve rod 38 to move along the water outlet passage 34, so as to open the water outlet passage 34. After the water tank assembly 3 is removed, the external force of the push rod 16 on the valve rod 38 disappears, and the valve rod 38 and the sealing member 39 return to the original position under the elastic force of the resilient 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 flow out.

[0135] In this embodiment, the resilient member for telescopic installation of the water tank assembly 3 and the resilient member required by the valve assembly 36 are the same part, that is, the water tank assembly pop-out structure and the water outlet opening and closing structure of the water tank assembly share one resilient member, so as to simplify the structure of the product.

[0136] Of course, in other schemes, the resilient member for telescopic installation of the water tank assembly 3 and the resilient member required by the valve assembly 36 can also be two independent parts.

[0137] Specifically, one end of the valve rod 38 penetrates the inlet of the water outlet passage 34 into the water containing cavity, and the sealing member 39 is sealingly installed at the inlet of the water outlet passage 34. The valve rod 38 can drive the sealing member 39 to move away from the outlet of the water outlet passage 34 to open the inlet of the water outlet passage 34 by pushing the valve rod 38 along the water outlet passage 34. In this arrangement, the sealing member 39 is arranged at the inlet of the water outlet passage 34, so that the inlet of the water outlet passage 34 can be opened or closed by the sealing member 39 to realize the opening and closing of the entire water outlet passage 34.

[0138] In any of the above embodiments, optionally, as Figure 4 ,Figure 5 and Figure 6 As shown, the water outlet channel 34 includes an outlet 342 and an inlet 344. When the valve stem 38 is in the fourth position, the seal 39 blocks the outlet 342. When the valve stem 38 is in the fifth position, the seal 39 avoids the outlet and connects the inlet 344 and the outlet 342.

[0139] In these embodiments, the seal 39 is disposed within the water outlet channel 34 and near the water outlet 342. When the water tank assembly 3 is not installed into the mounting housing 1, the valve stem 38 is in the fourth position, and the seal 39 blocks the water outlet 342, preventing water in the water tank housing 30 from leaking out through the water outlet channel 34. When the water tank assembly 3 is installed into the mounting housing 1, the push rod 16 is inserted into the water outlet channel 34 and pushes up the valve stem 38, placing it in the fifth position. At this time, the elastic element 4 is compressed, and the seal 39 and the valve stem 38 move together to the other side of the water inlet 344, connecting the water outlet 342 and the water inlet 344. This allows water in the water tank housing 30 to be discharged through the water outlet channel 34, facilitating water supply to the steam cooking appliance 200. When it is necessary to remove the water tank assembly 3, the limiting position between the water tank assembly 3 and the housing assembly is released, the valve stem 38 rebounds under the action of the elastic element 4, and the entire water tank assembly 3 is ejected. With this structure, when the water tank assembly 3 is ejected, the seal 39 can move along the outlet of the water outlet channel 34. In this way, the seal 39 can squeeze out the remaining water in the water outlet channel 34, avoiding the presence of too much water in the water outlet channel 34. This prevents the water tank assembly 3 from leaking when it is removed, thus avoiding any impact on the user experience.

[0140] Conversely, it can also be like Figure 7 and Figure 8 As shown, the seal 39 is positioned at the water inlet 344. When the water tank assembly 3 is not installed in the mounting housing, the seal 39 seals the water inlet 344. When the water tank assembly 3 is installed in the mounting housing 1, the push rod 16 pushes the valve rod 38 forward, causing the seal 39 to extend out of the water outlet channel 34, thereby opening the inlet of the water outlet channel 34 and allowing water to drain from the water tank assembly 3. However, because the water outlet channel 34 has a certain length and is generally placed horizontally, some residual water will remain in the water outlet channel 34 after the water tank assembly 3 is unlocked. During the removal of the water tank assembly 3, this water will drip out, negatively impacting the user experience.

[0141] Furthermore, it is advisable to slightly tilt the water outlet channel 34 downwards from the inlet to the outlet, which can also reduce the residual water in the water outlet channel 34.

[0142] In any of the above embodiments, optionally, as Figure 5 and Figure 7As shown, the elastic element 4 includes a spring that can extend or shorten.

[0143] In these embodiments, the use of a spring that can extend or shorten provides better elasticity to eject the water tank assembly 3 when it needs to be removed from the steam cooking appliance 200. Simultaneously, the spring also allows the valve body assembly to return to its initial installation position to block the water outlet passage 34, thereby preventing leakage of the water tank assembly 3 after it has been removed from the steam cooking appliance 200.

[0144] Of course, the elastic element 4 can also be other structures with a certain degree of elasticity and hardness, such as metal springs or rubber parts.

[0145] like Figure 9 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.

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.

[0147] In any of the above embodiments, optionally, as Figure 9 and Figure 10 As shown, the steam cooking appliance 200 includes a housing 6 and a door 7. The housing 6 has a food inlet / outlet 64 at its first end along a first direction. The door 7 is installed at the first end to open or close the food inlet / outlet 64. The water tank shell 30 is installed on the housing 6 and is arranged along the first direction. The installation port 14 is located at the first end of the housing 6 along the first direction.

[0148] The steam cooking appliance 200 provided according to an embodiment of this utility model includes a cooking chamber and a water tank assembly 3. The cooking chamber generates steam and performs cooking functions. The water tank assembly 3 is detachably installed on the cooking chamber to supply water to the cooking chamber. The cooking chamber includes a body 6 and a door 7. A cooking cavity 62 is provided inside the body 6, and the cooking cavity 62 communicates with a food inlet / outlet 64. The door 7 is installed on the body 6 and is used to open and close the food inlet / outlet 64. The water tank assembly 3 is installed on the side of the body 6 where the door 7 is provided, for example, on the front side of the body 6. The water tank assembly 3 can also be installed on the body 6 along the front side, and it can be pulled out in the front-back direction to achieve disassembly and assembly. Furthermore, the water tank assembly 3 is also placed front-back on the body 6, that is, it is installed horizontally on the body 6, not vertically.

[0149] Furthermore, such as Figures 1 to 10As shown, the water tank assembly 3 can be installed on the oven body 6 by the mounting port 14 in the first direction. The water tank assembly 3 comprises a water tank shell 30, the water tank shell 30 comprising a water storage cavity and a water inlet and outlet port 342 communicating with the water storage cavity, the water inlet and outlet port 342 being arranged at one end of the water tank shell 30 in the first direction; a cover 302 detachably mounted on the water tank shell 30 to open or close the water inlet and outlet port 342; a sealing ring arranged between the water tank shell 30 and the cover 302 to seal the gap between the water tank shell 30 and the cover 302.

At the same time, in order to ensure the sealing between the water tank shell 30 and the cover 302, a sealing ring is also arranged therebetween, which can seal the connection between the two, so as to avoid water leakage of the water tank assembly 3.

[0151] Among them, the water tank assembly arranged on the oven of the related scheme is directly arranged with a water inlet on the side wall of the water tank shell, without arranging a detachable cover, so that the inside of the water tank cannot be opened, thereby being very inconvenient for cleaning the inside of the water tank. In the present application, since the detachable cover 302 is specially arranged, when it is necessary to clean the water tank assembly 3, the cover 302 can be opened to clean the inside 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 302 to view the inside of the water tank shell 30, it is convenient for the user to check the dirt condition inside the water tank assembly 3 in time, so that the user can discover the dirt inside 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.

[0152] Among them, the first direction can be specifically the front-to-back direction of the cooking oven body, for example, the water tank assembly 3 can be disassembled from the front side of the cooking oven body. The cover 302 and the water tank shell 30 of the water tank assembly 3 are also assembled in the front-to-back direction, which is equivalent to that the water tank assembly 3 is installed horizontally on the cooking oven body, rather than vertically on the cooking oven body.

[0153] As shown in Figure 9 and Figure 10 As shown, the water tank assembly 3 is arranged close to the top of the steam cooking utensil 200 in the height direction of the steam cooking utensil 200.

[0154] Optionally, the steam cooking utensil 200 comprises an oven. Of course, the steam cooking utensil 200 can also be other devices that need a water tank.

[0155] In any of the above embodiments, optionally, as shown in Figure 9 and Figure 10 shown, the steam cooking appliance 200 further comprises: a heating device mounted on the cabinet 6, configured to heat the 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 transport the water in the water tank device 100 into the water receiving groove 9.

[0156] Further, the water in the water tank device 100 can flow into the water receiving groove 9 through the connecting pipe group 8 under the action of gravity.

[0157] In the above embodiments, optionally, as shown in Figure 2 shown, the water tank shell 30 comprises a first arc-shaped surface arranged along the circumferential direction of the water tank shell 30, two ends of the first arc-shaped surface arranged 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-shaped 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-shaped surface is located on the side of the first plane 304 close to the water inlet / outlet 342 of the water tank shell 30.

[0158] In this embodiment, the water tank shell 30 is substantially cylindrical in structure, and most of the outer wall surface thereof is arc-shaped, such as a circular arc-shaped surface. However, at least part of the outer wall surface of the water tank shell 30 is the first plane 304. By arranging the first plane 304, it is convenient to install the indication structure 306 and the first limiting structure 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.

[0159] In addition, by arranging the first plane 304, it is also convenient for the user to distinguish the front and back of the water tank shell 30, so that the water tank assembly 3 can be prevented from being installed incorrectly.

[0160] Further, the first outer side wall surface further comprises a second arc-shaped surface, the second arc-shaped 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 flat, so that the outer wall surface around the entire water inlet / outlet 342 is circular, thereby facilitating the cover body 302 to also be circular, so that the appearance of the entire water tank assembly 3 is more beautiful, and in particular when the water tank assembly 3 is used on an oven, etc., the water tank assembly 3 can be consistent with the shape of the knob, etc. on the oven, so that the overall aesthetic degree of the oven can be improved.

[0161] In the above embodiments, optionally, as shown in Figure 2As shown, the water tank shell 30 includes two oppositely arranged second outer side wall surfaces, each of which 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, and the water tank assembly 3 can be slidably mounted on the mounting shell 1 through the guide of the guide rib 308 and the guide groove.

[0162] In this embodiment, the water tank shell 30 is provided with a guide structure such as a guide rib 308 or a guide groove on the outer wall surfaces of the two oppositely arranged sides. Meanwhile, another guide structure that is mutually matched can be arranged on the cooking cabinet. In this way, the water tank assembly 3 can be more smoothly mounted on the cooking cabinet through the cooperation of the two guide structures, so as to facilitate 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, so that the water tank assembly 3 can be slidably mounted on the cooking cabinet along the first direction.

[0163] 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.

[0164] In related schemes, the retractable water tank of the oven mainly has two kinds: the first kind is to realize the extension and retraction of the water tank through a motor, which has the disadvantages of complex system, power-on, low reliability and high cost. The second kind is to realize the extension and retraction of the water tank through a rebound device by manual pressing, which has the disadvantages of complex system, low reliability and high cost.

[0165] The present embodiment proposes a retractable water tank scheme, which sets a limiting module and a spring to realize the extension and retraction control of the water tank through the cooperation of the limiting module and the spring. In this way, the two states of “ejection” and “pressing” of the water tank can be realized by pressing the water tank. In the present embodiment, the rebound device is integrated on the water tank / shell system, and the system is simpler, more reliable and lower in cost.
