[0035] See also Figure 1 , Figure 1 The schematic diagram of the structure of a cooking device 10 in one embodiment of the present application is shown. In one embodiment of the present application, a cooking device 10 is provided, which can be a steamer, a steam oven, etc., or any existing cooking device with a water tank, without limitation. Figure 1As shown, the cooking device 10 includes a water tank assembly 100 in any of the following embodiments, and also includes a door body 200 and an inner pot 300. The door body 200 covers the inner pot 300 to form a cooking cavity for cooking food together with the inner pot 300.

[0036] Combination Figure 2 As shown, Figure 2 The schematic diagram of the structure of the water tank assembly 100 in one embodiment of the present application is shown. The water tank assembly 100 provided in one embodiment of the present application can be applied to the above cooking device 10, but it is not limited thereto. The water tank assembly 100 includes a water storage tank 110, a water tank float 120, a display member 130 and a vent pipe 140.

[0037] In such Figure 1 In the embodiment shown, the water storage tank 110 is located below the inner tank 300, and a water storage chamber 111 is provided inside the water storage tank 110. Figure 2 The water storage tank 110 includes a box body 112 and a box cover 113 . The box body 112 has a space with an open top, and the box cover 113 is covered on the box body 112 to form a water storage chamber 111 .

[0038] like Figure 3 As shown, the water tank float 120 includes a float 121 that can float on the water surface and a hollow bracket 122 inside. The bracket 122 is connected to the bottom surface of the water storage chamber 111, and a water inlet 123 connected to the water storage chamber 111 is opened at the bottom of the bracket 122, so that the water inside the water storage chamber 111 can enter the bracket 122, so that the water level inside the bracket 122 is consistent with the water level of the water storage chamber 111. Figure 4 The float 121 is movably disposed inside the bracket 122, so that the float 121 can move up and down relative to the bracket 122 as the amount of water inside the water storage chamber 111 changes. Figure 4 As shown, the space inside the bracket 122 located on the side of the float 121 away from the water inlet 123 forms a first cavity 124, and the first cavity 124 is a space connected to the vent pipe 140. In theory, the first cavity 124 is not connected to the outside. Figure 4 Not shown in the figure, in actual use, the top of the bracket 122 and the box cover 113 together enclose a sealed first cavity 124, and the box cover 113 is provided with a connecting hole for connecting with the vent pipe 140 or for the vent pipe 140 to pass through.

[0039] The display element 130 is used to display the water volume inside the water storage chamber 111. The display element 130 is located outside the water storage tank 110 so that the user can observe the water volume inside the water storage tank 110 when the water storage tank 110 is not pumped out. Figure 1 As shown, the display member 130 is located in the door body 200 and is at a height higher than the water storage tank 110 for easy viewing by the user.

[0040] like Figure 1 As shown, in one embodiment, the door body 200 includes a main body 210 and a handle 220. The main body 210 is used to cover the inner container 300. The handle 220 is located on the end surface of the main body 210 away from the inner container 300 and protrudes from the main body 210. Figure 1 As shown, the handle 220 includes a display glass 221 with a display window 2211, and the display glass 221 is located on the side of the handle 220 away from the main body 210. The display element 130 is located opposite to the display window 2211, so that the display element 130 can be observed through the display window 2211 to know the water level in the water storage tank 110. The display element 130 is located on the side of the display glass 221 facing the main body 210, as shown in FIG. Figure 4 As shown, the display element 130 is located between the main body 210 and the display glass 221 to provide a certain degree of protection for the display element 130 .

[0041] like Figure 6 As shown, the display element 130 includes a display housing 131 with a hollow interior and a display mark 132. The display mark 132 is movably disposed inside the display housing 131. The display housing 131 is at least partially transparent so that the position of the display mark 132 can be observed through the display housing 131. More preferably, the display mark 132 is dark or bright in color for easy observation. Figure 6 As shown, the space inside the display housing 131 located on one side of the display mark 132 forms the second cavity 133, and the space inside the display housing 131 located on the other side of the display mark 132 is connected to the outside, so that when the air pressure inside the second cavity 133 increases, the air pressure can move the display mark 132 relative to the display housing 131. In this embodiment, the display housing 131 is further provided with an air hole 134, and the air hole 134 communicates with the outside and the space inside the display housing 131 located on the other side of the display mark 132. In this embodiment, the space inside the display housing 131 located on the lower side of the display mark 132 forms the second cavity 133. In other embodiments, the space inside the display housing 131 located on the upper side of the display mark 132 can also form the second cavity 133. When the display mark 132 can move left and right along the display housing 131, the second cavity 133 can also be a space located on the left or right side of the display mark 132, without limitation.

[0042] like Figure 2 As shown, the water tank assembly 100 further includes a vent pipe 140, and a vent passage 141 is provided inside the vent pipe 140. Figure 2 , Figure 4 and Figure 6As shown, the two ends of the ventilation channel 141 are connected to the first cavity 124 and the second cavity 133 respectively, and the first cavity 124, the second cavity 133 and the ventilation channel 141 together form a sealed space. When the volume of the first cavity 124 changes, the airflow will enter the second cavity 133 through the ventilation channel 141, so that the second cavity 133 changes synchronously, so that when the water volume in the water storage cavity 111 changes, the display mark 132 can rise or fall with the change of the water volume in the water storage cavity 111, so that the user can judge the water volume in the water storage cavity 111 by the position of the display mark 132 that is easy to observe. In the above scheme, the up and down movement of the display mark 132 is realized by the dynamic change of the sealed space connected up and down, and there is no intervention of electronic components, and the reliability is higher.

[0043] It is understandable that when the cooking device 10 starts working, although the water tank assembly 100 is located outside the inner pot 300, the increase in the temperature of the inner pot 300 will inevitably have some impact on the water tank assembly 100. Figure 7 As shown, in one embodiment, the water tank assembly 100 also includes a one-way valve 150, which is connected to the vent pipe 140. The one-way valve 150 can be connected to the vent channel 141 in an on-off manner, and the one-way valve 150 is arranged to be connected in one direction from the vent channel 141 to the outside of the vent pipe 140, so that when the cooking device 10 starts to work, when the sealed space formed by the first cavity 124, the second cavity 133 and the vent channel 141 is heated, the air pressure increases. In order to avoid the display mark 132 from moving up due to temperature changes, the one-way valve 150 is used to exhaust air to the outside to adjust the air pressure inside the sealed space, so that the air pressure inside the sealed space is balanced with the outside, so that the up and down movement of the display mark 132 is not affected by the increase in temperature of the inner pot 300 during the cooking process, thereby improving the accuracy of the display mark 132 indicating the water level in the water storage chamber 111.

[0044] like Figure 5 As shown, in one embodiment, the water tank assembly 100 also includes a water injection pipe 160, and a water injection channel 161 is provided inside the water injection pipe 160. The two ends of the water injection channel 161 are respectively connected to the water storage chamber 111 and the outside, so as to facilitate the injection of water into the water storage chamber 111, so that water can be directly added without pulling out the water storage tank 110, thereby solving the problem of difficulty in adding water to the existing water tank.

[0045] like Figure 5 As shown, in one embodiment, the water tank assembly 100 further includes a water injection tank 180 connected to the water injection pipe 160, and the water injection tank 180 is located above the water storage tank 110 to facilitate water injection when the water storage tank 110 is not pulled out. Figure 1 and Figure 2In the embodiment shown, the water injection groove 180 is located at the handle portion 220, and the opening of the water injection groove 180 is located at the top of the handle portion 220, so that it is more convenient to inject water into the water storage chamber 111. Figure 6 In the illustrated embodiment, the water injection pipe 160 passes through the display housing 131 along the moving direction of the display mark 132, and the display mark 132 is sleeved on the outer periphery of the water injection pipe 160, so that the water injection pipe 160 can guide the movement of the display mark 132 to prevent the display mark 132 from tilting.

[0046] Combination Figure 7 and Figure 8 As shown, in one embodiment, the one-way valve 150 is configured to disconnect the connection between the ventilation channel 141 and the outside of the ventilation pipe 140 when water is injected into the water storage chamber 111, so that during the water injection process, the sealed space is in a completely closed state. At this time, the float 121 rises and drives the display mark 132 to rise, thereby accurately indicating the amount of water in the water storage chamber 111.

[0047] like Figure 7 and Figure 8 As shown, in this embodiment, the water tank assembly 100 further includes a joint assembly 170, which is used to connect the water injection pipe 160 and the ventilation pipe 140 to realize the opening and closing of the one-way valve 150. In other embodiments, the one-way valve 150 can also be automatically controlled, for example, when a signal is triggered during water injection, the one-way valve 150 automatically closes after receiving the signal to disconnect the ventilation channel 141 from the outside of the ventilation pipe 140.

[0048] like Figure 7 and Figure 8 As shown, the joint assembly 170 includes an extension tube 171 connected to the vent tube 140, and an extension channel 1711 is provided inside the extension tube 171. The extension channel 1711 is selectively connected to the vent tube 141. At this time, it is only necessary to adjust the opening and closing of the extension channel 1711 and the vent tube 141, and it is not necessary to adjust the opening and closing of the one-way valve 150. The one-way valve 150 is connected to the side of the extension tube 171 away from the vent tube 140, and the one-way valve 150 is arranged to be connected from the extension channel 1711 to the outside of the extension tube 171 in a one-way manner. When the extension channel 1711 is connected to the vent tube 141, the one-way valve 150 can realize the connection between the vent tube 141 and the outside of the vent tube 140. When the extension channel 1711 is not connected to the vent tube 141, the connection between the vent tube 141 and the outside of the vent tube 140 is disconnected, and the sealed space is in a completely closed state.

[0049] like Figure 7 and Figure 8 As shown, in one embodiment, the joint assembly 170 further includes a movable stopper 172 movably disposed in the extension channel 1711. The movable stopper 172 is arranged in a Figure 8The occlusion position shown and Figure 7 Move between the connected positions shown, such as Figure 8 As shown, when the movable stopper 172 is in the blocking position, the movable stopper 172 blocks the extension channel 1711, so that the connection between the ventilation channel 141 and the outside of the ventilation pipe 140 is disconnected, and the sealed space is in a completely closed state. The movable stopper 172 is configured to move to the blocking position when the water storage chamber 111 is filled with water, so that the sealed space is in a completely closed state during the water filling process. At this time, the rise of the float 121 drives the display mark 132 to rise, thereby accurately indicating the water volume in the water storage chamber 111.

[0050] like Figure 7 and Figure 8 As shown, in one embodiment, the joint assembly 170 also includes an elastic member 173, which is connected to and acts on the movable stopper 172. The elastic member 173 has a tendency to drive the movable stopper 172 to move from the blocking position to the connecting position, so that when there is no external force, the elastic member 173 remains in the connecting position, thereby avoiding the movement of the display mark 132 caused by changes in temperature and air pressure in the sealed space.

[0051] like Figure 7 As shown, in one embodiment, the joint assembly 170 further includes a water guide pipe 174, the water guide pipe 174 includes an upstream end 1741, a downstream end 1742 and a transition section 1743 located between the upstream end 1741 and the downstream end 1742, the upstream end 1741 and the downstream end 1742 are respectively connected to different positions of the water injection pipe 160, and the water guide pipe 174 includes an upstream end 1741, a downstream end 1742 and a transition section 1743 located between the upstream end 1741 and the downstream end 1742. Figure 8 As shown, during the water injection process, water flows from the upstream end 1741 , flows through the transition section 1743 , and finally returns to the water injection pipe 160 at the downstream end 1742 .

[0052] like Figure 7 and Figure 8 As shown, in this embodiment, the water guide pipe 174 includes two pipes arranged up and down, and both ends located upstream and downstream in the flow direction of the water flow are located inside the water injection pipe 160 and connected to the water injection channel 161 in the water flow direction, but the other side of the pipe is located inside the ventilation pipe 140, and the water flows in the two pipes. The two pipes together constitute the transition section 1743 of the water guide pipe 174, and as shown in FIG. Figure 8 As shown, the ends of the two pipes located inside the ventilation pipe 140 are provided with holes facing each other up and down, so that water flows from the upper pipe to the lower pipe under the action of gravity. In other embodiments, a hole may be provided between the ends of the two pipes located inside the ventilation pipe 140. Figure 8 The connecting pipe shown by the dotted line, at this time, the water flows from the upper pipe to the lower pipe more reliably.

[0053] like Figure 7 and Figure 8 As shown, the joint assembly 170 also includes a lap joint body 175, two ends of one lap joint body 175 are respectively connected to the water injection pipe 160, two ends of the other lap joint body 175 are respectively connected to the ventilation pipe 140, and the water guide pipe 174 is connected between the two lap joint bodies 175 to make the installation of the water tank assembly 100 more stable and convenient.

[0054] like Figure 7 As shown, the transition section 1743 is provided with an opening 1744 connected to the extension channel 1711, and when the movable block 172 is in the connecting position, the movable block 172 passes through the opening 1744 and is located inside the water pipe 174 to block the water pipe 174, thereby isolating the vent pipe 140 and the water injection pipe 160, so as to prevent the sealed cavity from connecting to the water injection channel 161 in the non-water injection state, causing the display mark 132 to be inaccurate. The water flow in the water pipe 174 has a tendency to drive the movable block 172 to move from the connecting position to the blocking position, so as to use the pressure of the water flow to push the movable block 172 to move to the position as shown in FIG. Figure 8 The blocking position shown in the figure ensures that during the water injection process, there is no gas flow between the ventilation channel 141 and the outside, and the sealed space is in a completely closed state. At this time, the rise of the float 121 drives the display mark 132 to rise, thereby accurately indicating the water amount in the water storage chamber 111.

[0055] like Figure 7 As shown, in one embodiment, the axial direction of the opening 1744 is in the same direction as the flow direction of the water flow, so that the direction in which the movable stopper 172 moves from the connecting position to the blocking position is consistent with the direction of the water flow in the water pipe 174, so that the impact of the water flow can drive the movable stopper 172 to move. Figure 7 and Figure 8 From the perspective shown, the opening 1744 is opened at the end of the horizontal flow of the water in the pipe located above, and accordingly, the extension pipe 171, the movable stopper 172, the elastic member 173 and the one-way valve 150 are also arranged corresponding to the opening 1744. Figure 7 As shown, the opening 1744 can also be arranged at the end of the water flowing horizontally in the pipe located below, and accordingly, the extension pipe 171, the moving block 172, the elastic member 173 and the one-way valve 150 are also arranged corresponding to the opening 1744. Figure 7 At least one of the two positions shown in the figure is selected and set. Figure 8 In the embodiment shown, the opening 1744 is opened at the end of the horizontal flow of the water in the pipe located above.

[0056] In one embodiment, the transition section 1743 is partially inserted into the vent pipe 140, and the transition section 1743 is provided with a vent hole 1745 connected to the vent channel 141, so that the vent channel 141 is connected to the extension channel 1711 through the internal space of the transition section 1743, thereby preventing the water pipe 174 and the movable block 172 located at the connecting position from interfering with the connection between the vent channel 141 and the extension channel 1711. Figure 7 and Figure 8 In the embodiment shown in the figure, since the ends of the two pipes located inside the ventilation pipe 140 are provided with holes facing each other upward and downward, no holes are provided as shown in the figure. Figure 8 In the connecting pipe shown, the upper and lower holes of the upper pipe can both serve as vents 1745, and the upper hole of the upper pipe can be optionally provided.

[0057] In one embodiment, there is a gap 1746 between the transition section 1743 and the inner wall of the ventilation channel 141 so that the ventilation channel 141 is connected to the extension channel 1711, thereby preventing the water pipe 174 and the movable block 172 located at the connecting position from interfering with the connection between the ventilation channel 141 and the extension channel 1711.

[0058] The water tank assembly 100 in the above solution, when in use:

[0059] When water is injected, water flows from the water injection tank 180 and flows downward along the water injection pipe 160. When the water flows to the water guide pipe 174, the water pressure of the water flow pushes the movable stopper 172 to move to the position as shown in FIG. Figure 8 In the blocked position shown, the connection between the ventilation channel 141 and the outside is cut off and there is no gas flow, and the sealed space is in a completely closed state, so that the float 121 rises and drives the display mark 132 to rise, thereby accurately indicating the amount of water in the water storage chamber 111, and the user judges the water level in the water tank by the water level indicator.

[0060] After the water injection is completed, during the cooking process of the cooking device 10 cooking food, under the action of the elastic member 173, the movable block 172 is located at the connected position, at this time, the ventilation channel 141 and the water injection channel 161 are separated by the movable block 172, and when the water level in the water storage chamber 111 drops, the position of the display mark 132 drops synchronously, thereby displaying the water level in the water storage tank 110 in real time. Moreover, since the ventilation channel 141 and the extension channel 1711 are connected at this time, when the temperature of the inner pot 300 rises, the one-way valve 150 exhausts to the outside and adjusts the air pressure inside the sealed space, so that the air pressure inside the sealed space is balanced with the outside, and the up and down movement of the display mark 132 is not affected by the increase in the temperature of the inner pot 300 during the cooking process.

[0061] The water tank assembly 100 provided in the above scheme, by arranging a float 121 that can float on the water surface inside the water storage tank 110, and cooperating with the display mark 132 located outside the water storage tank 110, so that the two are in a connected sealed space, so that when the water level in the water storage chamber 111 changes, the display mark 132 can rise or fall with the change of the water volume in the water storage chamber 111, so that the user can judge the water volume in the water storage chamber 111 by the position of the display mark 132 that is easy to observe, and the up and down movement of the display mark 132 is realized by the dynamic change of the sealed space connected up and down, it does not involve any electronic components, and has higher reliability.
