Description

Technical Field

[0001] This application relates to the field of electrical technology, and in particular to water tank assemblies and cooking equipment. Background Technology

[0002] Cooking equipment with steaming functions, such as steam ovens and steam ovens, is usually equipped with a water tank. The water in the tank is heated to generate steam, which is used to steam food to keep it moist and prevent the surface of the food from drying out too quickly, thus maintaining the juiciness and texture of the food.

[0003] Water tanks are typically designed as pull-out tanks for easy refilling and regular cleaning to prevent scale buildup and bacterial growth. However, current technology usually involves either manual pull-out or electric push-out. Manual pull-out is laborious, especially for users with limited strength; while electric push-out is not only expensive but also requires a push rod motor, which is unreliable if it malfunctions. Therefore, a low-cost, highly reliable solution for automatically pushing out water tanks is needed. Utility Model Content

[0004] Therefore, it is necessary to provide a water tank component and cooking device to address the problems of difficult water tank ejection in existing cooking equipment, high cost and poor reliability of existing ejection structures.

[0005] A water tank assembly includes a fixed plate, a movable water tank, and a push-out mechanism. The fixed plate includes a water tank seat and a base spaced apart. The movable water tank is slidably connected to the water tank seat to move closer to or further away from the base. The push-out mechanism includes a push rod, a pressure rod, and an elastic element arranged sequentially. The elastic element is connected between the pressure rod and the base and has a tendency to drive the pressure rod away from the base. The push rod is slidably connected to the water tank seat and moves synchronously with the movable water tank. The pressure rod can selectively abut against either the push rod or the water tank seat. The pressure rod is configured to move synchronously with the push rod relative to the water tank seat when it abuts against the push rod.

[0006] In one embodiment, the ejection mechanism further includes a sleeve fixedly connected to the water tank seat, and the sleeve has a through hole arranged along the sliding direction of the movable water tank, the push rod passing through the through hole and slidably connected to the sleeve.

[0007] In one embodiment, the push rod includes sliders that protrude from the circumferential surface of the push rod and are spaced apart circumferentially along the push rod, and the sliders are located at the end of the push rod away from the movable water tank, and the inner wall of the sleeve is recessed with a guide groove adapted to the sliders.

[0008] In one embodiment, there are multiple guide grooves, all of which are distributed at intervals along the circumference of the sleeve, and the number of sliders is equal to and corresponds one-to-one with the number of guide grooves.

[0009] In one embodiment, the guide groove includes a full guide groove and a semi guide groove with different depths. The semi guide groove and the full guide groove are alternately distributed circumferentially on the sleeve. The depth of the semi guide groove is less than the depth of the full guide groove, and the depth to which the slider is inserted into the guide groove is not greater than the depth of the semi guide groove.

[0010] In one embodiment, the end face of the pressure rod facing the slider is provided with a force-receiving block. The number of force-receiving blocks is consistent with the number of full guide grooves and is set in a one-to-one correspondence. The diameter of the force-receiving block is larger than the aperture of the semi-guide groove but not larger than the aperture of the full guide groove.

[0011] In one embodiment, the end of the slider away from the movable water tank is provided with a transmission surface, and the end face of the force-bearing block facing the slider is provided with a guide surface opposite to the transmission surface. At least one of the transmission surface and the guide surface is an inclined surface, so that when the slider and the pressure rod abut, the force between them has the tendency to drive the pressure rod to rotate and abut against the sleeve.

[0012] In one embodiment, the sleeve includes guide posts for spacing adjacent guide grooves, the end face of the guide post facing the base being an abutment surface, and the abutment surface being inclined in the same direction as either the transmission surface or the guide surface.

[0013] In one embodiment, the end face of the semi-guide groove facing the base is an extension surface, the extension surface is inclined in the same direction as the abutment surface, and the extension surface and the abutment surface of the guide post connected to the semi-guide groove and located in the upward direction of the extension surface are on the same plane.

[0014] In one embodiment, the transmission surface is an inclined surface, and each slider further includes a back inclined surface opposite to the inclination direction of the transmission surface at one end away from the movable water tank.

[0015] A cooking appliance includes a water tank assembly as described in any of the above embodiments.

[0016] The water tank assembly provided in the above solution features a pressure rod that can selectively abut against the top rod and the water tank seat, and an elastic element that moves the pressure rod and the movable water tank out of the water tank seat. When the pressure rod abuts against the top rod, the elastic element and the pressure rod simultaneously move the top rod and the movable water tank relative to the water tank seat away from the base, providing assistance when the movable water tank is pushed out. When the pressure rod abuts against the water tank seat, the force exerted by the elastic element on the pressure rod cannot be transmitted to the top rod, thus preventing the top rod and the movable water tank from moving out of the water tank seat. This solution uses a mechanical structure to provide assistance when the movable water tank is pushed out. It does not require a control unit, has low cost, and eliminates the problem of failure to push out due to electrical control component malfunction, resulting in higher reliability.

[0036] See Figure 1 , Figure 1 A cross-sectional schematic diagram of a cooking device 10 according to an embodiment of this application is shown. The cooking device 10 provided in this embodiment can be a steam oven, a steam oven, or any existing cooking device. The cooking device 10 includes an inner liner 200 with a cooking cavity and a door 300 covering the inner liner 200. It also includes a water tank assembly 100 as described in any of the following embodiments, the water tank assembly 100 being located above the inner liner 200. The cooking device 10 also includes a top baffle 400 located above the door 300, the top baffle 400 having an opening for the removal of the movable water tank 120 described below from the water tank assembly 100.

[0037] Combination Figure 2 As shown, Figure 2A schematic diagram of the structure of a water tank assembly 100 in one embodiment of this application is shown. The water tank assembly 100 provided in one embodiment of this application can be applied to the cooking equipment 10 described above and used to supply water for cooking ingredients, and can also be applied to other scenarios.

[0038] like Figure 2 As shown, the water tank assembly 100 includes a fixed plate 110, a movable water tank 120, and a push-out mechanism 130. The fixed plate 110 includes a water tank seat 111 and a base 112 spaced apart. Figure 2 In the illustrated embodiment, the fixing plate 110 further includes a fixedly disposed partition 113 located above the inner liner 200 to separate the inner liner 200 from the movable water tank 120 and electronic components located above the partition 113, thereby preventing the movable water tank 120 and electronic components from being affected by the high temperature of the inner liner 200. The water tank base 111 and the base 112 are respectively connected to the partition 113 at intervals and are both located on the side of the partition 113 away from the inner liner 200.

[0039] Combination Figure 3 and Figure 4 , Figure 3 and Figure 4 The diagram shows different sliding positions of the movable water tank 120 relative to the water tank base 111 in one embodiment of this application. The movable water tank 120 is slidably connected to the water tank base 111, and the movable water tank 120 moves closer to or further away from the base 112 when it slides relative to the water tank base 111.

[0040] Combination Figure 5 As shown, the ejection mechanism 130 includes a push rod 131, a pressure rod 132, and an elastic element 133 arranged sequentially. The elastic element 133 is connected between the pressure rod 132 and the base 112 and has a tendency to drive the pressure rod 132 away from the base 112, i.e., it has a tendency to drive the movable component to move away from the base 112. During use, the elastic element 133 remains in a compressed state. In this embodiment, the elastic element 133 is illustrated as a spring. In other embodiments, the elastic element 133 can also be other components with restoring properties.

[0041] Combination Figure 6 As shown, the push rod 131 is slidably connected to the water tank base 111 and moves synchronously with the movable water tank 120. In this embodiment, the water tank base 111 has a groove 121, and the push rod 131 is partially inserted into the groove 121. The end face of the groove 121 facing the base 112 is the force-bearing surface 122. The push rod 131 abuts against the force-bearing surface 122 to move synchronously with the movable water tank 120. Furthermore, in conjunction with... Figure 7 and Figure 8The pressure rod 132 can selectively abut against either the top rod 131 or the water tank seat 111. When the pressure rod 132 abuts against the top rod 131, it moves synchronously with the top rod 131 relative to the water tank seat 111. When there is no external force acting on the moving water tank 120, under the action of the elastic element 133, the elastic element 133 pushes the pressure rod 132, causing the top rod 131 and the moving water tank 120 to move synchronously relative to the water tank seat 111 in a direction away from the base 112. When the moving water tank 120 is pressed or pushed, the external force overcomes the elastic force of the elastic element 133, causing the moving water tank 120 to move synchronously with the top rod 131 and the pressure rod 132 in a direction closer to the base 112. When the pressure rod 132 abuts against the water tank seat 111, the force exerted by the elastic element 133 on the pressure rod 132 cannot be transmitted to the top rod 131, and thus will not drive the top rod 131 and the moving water tank 120 to move out of the water tank seat 111.

[0042] Combination Figure 9 and Figure 10 As shown, in one embodiment, the ejection mechanism 130 further includes a sleeve 134, which is fixedly connected to the water tank base 111. In this embodiment, the sleeve 134 is welded to the water tank base 111 by means of a screw; in other embodiments, the sleeve 134 can also be connected by means of screws or other methods. The sleeve 134 is provided with a through hole 1341 provided along the sliding direction of the movable water tank 120, combined with... Figure 3 and Figure 4 The push rod 131 is inserted into the through hole 1341 and slidably connected to the sleeve 134 so that the push rod 131 can move relative to the water tank seat 111.

[0043] like Figure 11 As shown, in one embodiment, the push rod 131 includes sliders 1311 protruding from the circumferential surface of the push rod 131 and spaced circumferentially along the push rod 131. The sliders 1311 are located at the end of the push rod 131 away from the movable water tank 120 and are used to abut against the pressure rod 132. Figure 9 and Figure 10 As shown, the inner wall of the sleeve 134 is recessed with a guide groove 1342 that matches the slider 1311. The slider 1311 is slidably disposed in the guide groove 1342 so as to guide the movement of the push rod 131 through the guide groove 1342.

[0044] like Figure 9 and Figure 10 As shown, in one embodiment, there are multiple guide grooves 1342, all of which are distributed at intervals along the circumference of the sleeve 134, and the number of sliders 1311 is equal to the number of guide grooves 1342 and corresponds one-to-one, so that the force on the push rod 131 and the sleeve 134 is uniform.

[0045] like Figure 9 and Figure 10As shown, in one embodiment, the guide groove 1342 includes a full guide groove 13421 and a semi-guide groove 13422 of different depths. The semi-guide groove 13422 and the full guide groove 13421 are alternately distributed circumferentially on the sleeve 134. The depth of the semi-guide groove 13422 is less than the depth of the full guide groove 13421, and as shown... Figure 8 As shown, the depth to which the slider 1311 is inserted into the guide groove 1342 is no greater than the depth of the semi-guide groove 13422, so that the slider 1311 can slide normally in both the semi-guide groove 13422 and the full guide groove 13421. In this embodiment, as... Figure 8 and Figure 11 As shown, the number of sliders 1311 is the same as the number of guide grooves 1342, and the sliders 1311 are respectively embedded in the corresponding guide grooves 1342 to slide and connect to the sleeve 134.

[0046] like Figure 11 As shown, in one embodiment, the end face of the pressure rod 132 facing the slider 1311 is provided with a force-receiving block 1321. The number of force-receiving blocks 1321 is the same as the number of full guide grooves 13421 and they are arranged in a one-to-one correspondence. The diameter of the force-receiving block 1321 is larger than the aperture of the semi-guide groove 13422 but not larger than the aperture of the full guide groove 13421. When the force-receiving block 1321 corresponds to the full guide groove 13421, the force-receiving block 1321 is as follows: Figure 8 As shown, it can be inserted into the full guide groove 13421 and slide relative to the sleeve 134. At this time, the pressure rod 132 abuts against the top rod 131 so as to move synchronously with the top rod 131 relative to the water tank seat 111.

[0047] like Figure 11As shown, in one embodiment, the end of the slider 1311 facing away from the movable water tank 120 is provided with a transmission surface 1312, and the end face of the force block 1321 facing the slider 1311 is provided with a guide surface 1322 opposite to the transmission surface 1312. At least one of the transmission surface 1312 and the guide surface 1322 is an inclined surface, so that when the slider 1311 and the pressure rod 132 abut, the force between the two has the tendency to drive the pressure rod 132 to rotate and abut against the sleeve 134. The force between the two abutting each other generates a component force that causes the pressure rod 132 to rotate due to acting on the inclined surface, so that when the pressure rod 132 is disengaged from the full guide groove 13421, it can rotate relative to the sleeve 134 and the top rod 131. Meanwhile, since the diameter of the pressure rod 132 is larger than the aperture of the semi-guide groove 13422, when the pressure rod 132 rotates and is positioned in the semi-guide groove 13422, it will be unable to insert into the semi-guide groove 13422. Under the elastic force of the elastic element 133, it will abut against the end face of the sleeve 134 facing the base 112. Since the sleeve 134 is fixedly connected to the water tank seat 111, the force exerted by the elastic element 133 on the pressure rod 132 cannot be transmitted to the top rod 131, and therefore will not cause the top rod 131 and the moving water tank 120 to move out of the water tank seat 111. In this embodiment, both the transmission rod and the guide surface 1322 are inclined surfaces, and their inclination directions are the same. However, in this embodiment, their slopes are different for illustrative purposes only and are not intended to be limiting.

[0048] In such Figure 11 In the embodiment shown, the transmission surface 1312 is an inclined surface, and each slider 1311 also includes a back inclined surface 1313 opposite to the inclination direction of the transmission surface 1312 at one end away from the moving water tank 120, so that the area of ​​the slider 1311 abutting against the force block 1321 is smaller, making it easier to drive the pressure rod 132 to rotate.

[0049] like Figure 9 and Figure 10 As shown, in one embodiment, the sleeve 134 includes guide posts 1343 for spacing adjacent guide grooves 1342, such as... Figure 9 and Figure 10As shown, the end face of the guide post 1343 facing the base 112 is the abutment surface 13431, and the abutment surface 13431 is inclined in the same direction as either the transmission surface 1312 or the guide surface 1322, so as to guide the force-bearing block 1321, making it easier for the force-bearing block 1321 to be inserted into the full guide groove 13421, or to align the force-bearing block 1321 with the half guide groove 13422. In this embodiment, both the transmission surface 1312 and the guide surface 1322 are inclined surfaces, and the abutment surface 13431 can be inclined in the same direction as either the transmission surface 1312 or the guide surface 1322. In other embodiments, if the transmission surface 1312 is an inclined surface, then the abutment surface 13431 is inclined in the same direction as the transmission surface 1312; if the guide surface 1322 is an inclined surface, then the abutment surface 13431 is inclined in the same direction as the guide surface 1322.

[0050] like Figure 9 and Figure 10 As shown, in one embodiment, the end face of the semiguide groove 13422 facing the base 112 is an extension surface 1344. The extension surface 1344 and the abutment surface 13431 are inclined in the same direction, and the extension surface 1344 and the abutment surface 13431 of the guide post 1343 connected to the semiguide groove 13422 and located in the upward direction of the extension surface 1344 are in the same plane, so that when the force block 1321 is aligned with the semiguide groove 13422, there is a height difference between the semiguide groove 13422 and the guide post 1343 located in the downward direction of the extension surface 1344, so that the force block 1321 remains in contact with and against the extension surface 1344 of the semiguide groove 13422.

[0051] The water tank assembly 100 provided in the above solution, when in use:

[0052] When pushing is required: Pushing the movable water tank 120, the external force overcomes the elastic force of the elastic element 133, causing the movable water tank 120 to drive the top rod 131 and the pressure rod 132 to move synchronously towards the base 112, until the top rod 131 drives the pressure rod 132 to move until the force-bearing block 1321 of the pressure rod 132 disengages from the full guide groove 13421. At this time, the force-bearing block 1321 loses the abutting force of the guide post 1343 in its circumferential direction, and the abutting force of the top rod 131 and the pressure rod 132... Under the relay action, since the contact force between the slider 1311 and the force-bearing block 1321 has a component force in the circumferential direction, the pressure rod 132 rotates relative to the sleeve 134, causing the force-bearing block 1321 to align with the position of the semi-guide groove 13422. At this time, when the external force is lost, the pressure rod 132 abuts against the water tank seat 111, and the force applied by the elastic element 133 to the pressure rod 132 cannot be transmitted to the top rod 131, and will not drive the top rod 131 and the moving water tank 120 to move out of the water tank seat 111.

[0053] When it needs to be pushed out: Press the moving water tank 120, and the external force overcomes the elastic force of the elastic element 133, causing the top rod 131 to move a short distance toward the pressure rod 132. At this time, the slider 1311, which is slidably set in the semi-guide groove 13422 in the top rod 131, will abut and drive the force block 1321 to move toward the base 112. When the force block 1321 moves to the point of disengaging from the semi-guide groove 13422 and losing the abutting force of the guide post 1343 in its circumferential direction, under the action of the abutting force of the top rod 131 and the pressure rod 132, the pressure rod 132 rotates relative to the sleeve 134, so that the force block 1321 is aligned with the position of the full guide groove 13421. Then, under the action of the elastic element 133, the force block 1321 is inserted into the full guide groove 13421 and pushes the pressure rod 132. The pressure rod 132 drives the top rod 131 and the moving water tank 120 to move synchronously relative to the water tank seat 111 in a direction away from the base 112, so as to assist or automatically pop out when the moving water tank 120 is pushed out.

[0054] In the above-described scheme, the water tank assembly 100 is equipped with a pressure rod 132 that can selectively abut against the top rod 131 and the water tank seat 111, and an elastic element 133 that can drive the pressure rod 132 and the movable water tank 120 to move out of the water tank seat 111. This allows the elastic element 133 and the pressure rod 132 to drive the top rod 131 and the movable water tank 120 to move synchronously relative to the water tank seat 111 in a direction away from the base 112 when the pressure rod 132 abuts against the top rod 131, thus providing assistance when the movable water tank 120 is pushed out. However, when the pressure rod 132 abuts against the water tank seat 111, the force exerted by the elastic element 133 on the pressure rod 132 cannot be transmitted to the top rod 131, and therefore will not drive the top rod 131 and the movable water tank 120 to move out of the water tank seat 111. In this solution, a mechanical structure is used to assist the mobile water tank 120 when it is pushed out. It does not require a control unit, has low cost, and does not have the problem of being unable to push out due to failure of electronic control components, thus having higher reliability.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
