Description
Technical Field
[0001] The utility model relates to the field of cooking equipment, in particular to a water tank component and cooking equipment having the water tank component. Background Art
[0002] Cooking equipment with steaming function, such as steam boxes and steam ovens, is generally equipped with a water tank assembly and a steam generator. In the steaming mode, the water in the water tank is input into the steam generator and heated into steam in the steam generator. The generated steam is used to heat food. For example, the Chinese invention patent with patent number ZL 202110121313.2 (authorization announcement number CN112932254A), the Chinese utility model patent with patent number ZL 202022599840.8 (authorization announcement number CN214760654U), etc.
[0003] Furthermore, in the prior art, the water tank assembly generally adopts a water inlet mechanism including a water pump and a solenoid valve, for example, the Chinese utility model patent with patent number ZL201922163364.2 (authorization announcement number CN211795859U) discloses a steam-bake micro-integrated machine, including a water tank, the water tank having a first water outlet, a second water outlet and a water return outlet, the first water outlet is connected to the water inlet of the inner pot through a first water inlet pipe, and a first water pump solenoid valve assembly is installed on the first water inlet pipe. However, the use of a water inlet mechanism including a water pump not only makes the internal structure of the cooking device complicated and increases the production cost, but also the electrical devices such as the water pump are easily damaged, which affects the service life of the cooking device. Summary of the invention
[0004] The first technical problem to be solved by the utility model is to provide a water tank assembly which does not need to be provided with a water outlet pump in view of the prior art.
[0005] The second technical problem to be solved by the utility model is to provide a water tank assembly which does not require a water outlet pump and has a relatively high water outlet efficiency in view of the prior art.
[0006] The third technical problem to be solved by the present invention is to provide a cooking device with the water tank assembly according to the prior art.
[0007] The utility model solves at least one of the above technical problems by adopting a technical solution: a water tank assembly, comprising a water tank seat and a water tank accommodated in the water tank seat, the water tank seat having a water tank port for the water tank to enter and exit, and a water outlet is provided at the lower end of the water tank, and correspondingly, a water outlet joint for forming a fluid connection with the water outlet is provided at the lower end of the water tank seat, characterized in that:
[0008] The straight line where the central axis of the water outlet is located is inclined downwardly relative to the horizontal plane along the water outlet direction. Correspondingly, the straight line where the central axis of the above-mentioned water outlet joint is located is also inclined downwardly relative to the horizontal plane along the water outlet direction, and the two are parallel. Moreover, the straight line where the central axis of the water outlet is located is located above the straight line where the central axis of the water outlet joint is located.
[0009] Furthermore, it also includes a piston assembly, which includes a piston, a first sealing ring and a return spring, wherein the piston is inserted into the water outlet so as to be movable back and forth along the linear direction where the central axis of the water outlet is located, and the first sealing ring is arranged at the upper end of the piston along the length direction.
[0010] When the water tank is not placed in the water tank seat, the upper end of the piston and the first sealing ring close the water outlet, and the return spring is in the initial state. When the water tank is inserted into the water tank seat and in place, the water tank seat acts on the piston to move the upper end of the piston and the first sealing ring upward and away from the water outlet, and the water outlet is opened. The return spring is compressed and causes the piston to have a tendency to move downward and reset to close the water outlet. In this way, the opening and closing of the water outlet of the water tank is controlled by the piston assembly: when the water tank is not inserted into the water tank seat, the piston assembly closes the water outlet. When the water tank is inserted into the water tank seat and in place, the piston is forced to move upward to open the water outlet. At this time, the water in the water tank can flow out through the water outlet. When the water tank is taken out of the water tank seat, the piston moves downward and resets under the elastic force of the return spring to close the water outlet again.
[0011] Furthermore, the lower end of the piston is provided with a limiting edge along the circumferential direction, and the return spring is sleeved on the piston and is limited along the circumferential direction between the lower edge of the water outlet and the limiting edge. Thus, the piston can be stably arranged, and when the piston is forced to move upward, the distance between the lower edge of the water outlet and the limiting edge is shortened, and the return spring is compressed and deformed.
[0012] Furthermore, the piston comprises a body extending along its length direction, the cross section of the body is in a cross shape, and the upper end of the body is provided with a head, and the first sealing ring is sleeved on the head.
[0013] Furthermore, when the water tank is not accommodated in the water tank seat, the head and the first sealing ring close the water outlet, and when the water tank is accommodated in the water tank seat, the body is inserted into the water outlet, so that water can flow out of the water tank through the gap between the edge of the water outlet and the body, and a limiting ring is provided on the periphery of the lower end portion of the body, and the upper surface of the limiting ring constitutes the limiting circumference, so that the piston and the return spring can interact better, thereby ensuring the reliability of the opening and closing control of the water outlet.
[0014] Furthermore, a water outlet sleeve is sleeved on the outer surface of the water tank at the water outlet, and the water outlet sleeve extends along the straight line direction where the central axis of the water outlet is located, and when the piston is in a moving state, the limit ring can move back and forth in the circumferential direction relative to the inner circumference of the water outlet sleeve. The guidance of the water outlet sleeve can make the piston move back and forth more smoothly, further improving the reliability of the opening and closing control of the water outlet.
[0015] Furthermore, a water inlet is provided at the lower end of the water tank seat, and the water inlet is arranged opposite to the water outlet and is used to connect the water outlet with the water outlet joint in fluid communication.
[0016] It also includes a water outlet seat, which is a truncated cone-shaped cover body and is connected to the water outlet on the outer surface of the water tank seat. A connecting port is eccentrically opened on the end wall of the water outlet seat, and the water outlet joint is connected to the connecting port.
[0017] The water outlet sleeve is inserted into the water outlet seat, so that the water tank and the water tank seat can be firmly inserted and connected, and a limit block is provided on the inner end surface of the water outlet seat at one side of the connecting port.
[0018] When the water tank is inserted into the water tank seat, the lower end of the piston abuts against the limit block to move the piston upward and compress the return spring. In this way, the water tank seat can push the piston upward through the limit block to move the piston upward and open the water outlet.
[0019] Furthermore, the shape of the stop block is cylindrical, and the stop block is arranged along the straight line direction where the central axis of the water outlet is located, and the upper end of the stop block can be against the lower end of the piston in the circumferential direction, and one side of the stop block is axially penetrated through the break to form a water-passing gap, and the water-passing gap is opposite to the connecting port. In this way, the water flowing out of the water outlet flows into the stop block through the water-passing port, and then flows into the water outlet joint from the connecting port through the water-passing gap, which can better ensure that the water flowing out of the water outlet enters the water outlet joint.
[0020] Furthermore, the circle where the lower port of the limit block is located partially overlaps with the circle where the connecting port is located, so that water can flow more smoothly into the connecting port from the water outlet gap.
[0021] Furthermore, it also includes a second sealing ring, which is circumferentially sandwiched between the water outlet sleeve and the edge of the water outlet, and the lower edge of the second sealing ring extends radially upward along the circumferential direction to form a third sealing ring, which is circumferentially sandwiched between the edge of the water outlet seat and the edge of the water outlet. The second sealing ring and the third sealing ring can ensure the sealing of the connection between the water outlet sleeve and the water outlet seat to avoid water leakage.
[0022] The technical solution adopted to further solve the third technical problem mentioned above is: a cooking device, characterized in that it includes the water tank assembly as described above.
[0023] Compared with the prior art, the utility model has the advantages that: the straight line where the central axis of the water outlet of the water tank is located is inclined downwardly relative to the horizontal plane along the water outlet direction, so that the water in the water tank can flow out through the water outlet under the action of its own gravity, and at the same time, the straight line where the central axis of the water outlet joint on the water tank seat is located is also inclined downwardly relative to the horizontal plane along the water outlet direction, so that the water flowing to the water outlet joint can also flow out from the water outlet joint under the action of its own gravity, thereby realizing water outlet of the water tank assembly without the need for a water outlet pump, and the straight line where the central axis of the water outlet is located is located above the straight line where the central axis of the water outlet joint is located, and the water flow is accelerated by utilizing the upper and lower drop differences, thereby improving the water outlet efficiency of the water tank assembly.

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0034] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present utility model can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.
[0035] A cooking device (e.g., a steamer, a steam oven, etc.) includes: Figures 1 to 9 The water tank assembly shown includes a water tank seat 2 and a water tank 1 accommodated in the water tank seat 2. The water tank seat 2 has a water tank port 20 for the water tank 1 to enter and exit, and a water outlet 10 is provided at the lower end of the water tank 1. Accordingly, a water outlet joint 3 is provided at the lower end of the water tank seat 2 for forming a fluid connection with the water outlet 10. The straight line a where the central axis of the water outlet 10 is located is inclined downward along the water outlet direction relative to the horizontal plane, and accordingly, the straight line b where the central axis of the water outlet joint 3 is located is also inclined downward along the water outlet direction relative to the horizontal plane, and the two are parallel, and the straight line a where the central axis of the water outlet 10 is located is located above the straight line b where the central axis of the water outlet joint 3 is located.
[0036] As can be seen from the above, in the present utility model, the straight line a where the central axis of the water outlet 10 of the water tank 1 is located is tilted downward along the water outlet direction relative to the horizontal plane, so that the water in the water tank 1 can flow out through the water outlet 10 under the action of its own gravity. At the same time, the straight line b where the central axis of the water outlet joint 3 on the water tank seat 2 is located is also tilted downward along the water outlet direction relative to the horizontal plane, so that the water flowing to the water outlet joint 3 can also flow out from the water outlet joint 3 under the action of its own gravity, thereby realizing the water outlet of the water tank assembly without the need for a water outlet pump. In addition, the straight line a where the central axis of the water outlet 10 is located is located above the straight line b where the central axis of the water outlet joint 3 is located, and the water flow is accelerated by using the up and down drop, thereby improving the water outlet efficiency of the water tank assembly.
[0037] Specifically, in this embodiment, the water tank 1 and the water tank seat 2 are both square in shape, wherein the water tank port 20 of the water tank seat 2 is opened at its front end, and the outer bottom surface of the water tank 1 and the inner bottom surface of the water tank seat 2 can slide relative to each other in the front-to-back direction, thereby facilitating the water tank 1 to be inserted into the water tank seat 2 or taken out from the water tank seat 2.
[0038] Furthermore, the water tank assembly also includes a piston assembly 4, which includes a piston 41, a first sealing ring 42 and a reset spring (not shown). The piston 41 is inserted into the water outlet 10 so as to be movable back and forth along the straight line a direction where the central axis of the water outlet 10 is located, and the first sealing ring 42 is arranged at the upper end of the piston 41 along the length direction. When the water tank 1 is not accommodated in the water tank seat 2, the upper end of the piston 41 and the first sealing ring 42 close the water outlet 10, and the reset spring is in an initial state. When the water tank 1 is inserted into the water tank seat 2 and in place, the water tank seat 2 acts on the piston 41 to move the upper end of the piston 41 and the first sealing ring 42 upward and out of the water outlet 10, and the water outlet 10 is opened. The reset spring is compressed and causes the piston 41 to have a tendency to move downward and reset to close the water outlet 10. In this way, the opening and closing of the water outlet 10 of the water tank 1 is controlled by the piston assembly 4:
[0039] When the water tank 1 is not inserted into the water tank seat 2, the piston assembly 4 closes the water outlet 10. When the water tank 1 is inserted into the water tank seat 2 and in place, the piston 41 is forced to move upward to open the water outlet 10. At this time, the water in the water tank 1 can flow out through the water outlet 10. When the water tank 1 is taken out of the water tank seat 2, the piston 41 moves downward and resets under the elastic force of the reset spring to close the water outlet 10 again.
[0040] In this embodiment, preferably, the lower end of the piston 41 is provided with a limiting edge 431 along the circumferential direction, and the return spring is sleeved on the piston 41 and is limited between the lower edge of the water outlet 10 and the limiting edge 431 along the circumferential direction. Thus, the piston 41 can be stably arranged, and when the piston 41 is forced to move upward, the distance between the lower edge of the water outlet 10 and the limiting edge 431 is shortened, and the return spring is compressed and deformed. Specifically, the piston 41 includes a body 411 extending along its length direction, the cross section of the body 411 is in a cross shape, and the upper end of the body 411 has a head 412, and the first sealing ring 42 is sleeved on the head 412. Furthermore, when the water tank 1 is not accommodated in the water tank seat 2, the head 412 and the first sealing ring 42 close the water outlet 10; when the water tank 1 is accommodated in the water tank seat 2, the main body 411 is inserted into the water outlet 10, so that water can flow out of the water tank 1 through the gap between the edge of the water outlet 10 and the main body 411, and a limiting ring 43 is provided on the periphery of the lower end of the main body 411, and the upper surface of the limiting ring 43 constitutes the limiting circumference 431, so that the piston 41 can better interact with the return spring, thereby ensuring the reliability of the opening and closing control of the water outlet 10.
[0041] Furthermore, a water outlet sleeve 5 is sleeved on the outer surface of the water tank 1 at the water outlet 10, and the water outlet sleeve 5 extends along the straight line a where the central axis of the water outlet 10 is located, and when the piston 41 is in a moving state, the limit ring 43 can move back and forth in the circumferential direction relative to the inner circumferential surface of the water outlet sleeve 5. The guidance of the water outlet sleeve 5 can make the piston 41 move back and forth more smoothly, further improving the reliability of the opening and closing control of the water outlet 10. In this embodiment, the water outlet sleeve 5 and the water tank 1 are an integral part.
[0042] Furthermore, a water passage 21 is provided at the lower end of the water tank seat 2, and the water passage 21 is arranged opposite to the water outlet 10, and is used to make the water outlet 10 fluidly connected with the water outlet joint 3. A water outlet seat 6 is also included, which is a truncated cone-shaped cover body, and is connected to the water passage 21 on the outer surface of the water tank seat 2, and a connection port 61 is eccentrically provided on the end wall of the water outlet seat 6, and the water outlet joint 3 is connected to the connection port 61. The water outlet sleeve 5 is inserted into the water outlet seat 6, so that the water tank 1 and the water tank seat 2 can be firmly inserted, and a limit block 62 is provided on the inner end surface of the water outlet seat 6 on one side of the connection port 61. When the water tank 1 is inserted into the water tank seat 2, the lower end of the piston 41 abuts against the limit block 62 to move the piston 41 upward, and the return spring is compressed. In this way, the water tank seat 2 can push the piston 41 upward through the limit block 62, so that the piston 41 moves upward to open the water outlet 10.
[0043] Preferably, the shape of the above-mentioned stop block 62 is cylindrical, and the stop block 62 is arranged along the direction of the straight line a where the central axis of the water outlet 10 is located, and the upper end of the stop block 62 can be against the lower end of the above-mentioned piston 41 along the circumferential direction, and one side of the stop block 62 is axially penetrated through the break to form a water-passing gap 620, and the water-passing gap 620 is opposite to the above-mentioned connecting port 61. In this way, the water flow out of the water outlet 10 flows into the stop block 62 through the water-passing port 21, and then flows into the water outlet joint 3 from the connecting port 61 through the water-passing gap 620, which can better ensure that the water out of the water outlet 10 enters the water outlet joint 3. Further preferably, the circle where the lower port of the above-mentioned stop block 62 is located coincides with the circle where the above-mentioned connecting port 61 is located, so that the water flow can enter the connecting port 61 more smoothly from the water outlet gap. In this embodiment, the above-mentioned stop block 62 and the water outlet seat 6 are an integral part, and the water outlet seat 6 and the water outlet joint 3 are also an integral part.
[0044] Furthermore, a second sealing ring 7 is included, which is circumferentially sandwiched between the water outlet sleeve 5 and the edge of the water outlet 21, and the lower edge of the second sealing ring 7 extends radially upward in the circumferential direction to form a third sealing ring 71, which is circumferentially sandwiched between the edge of the water outlet seat 6 and the edge of the water outlet 21. The second sealing ring 7 and the third sealing ring 71 can ensure the sealing of the connection between the water outlet sleeve 5 and the water outlet seat 6 to avoid water leakage.
