Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a steam generating device and a cooking utensil. Background Art

[0002] In cooking appliances such as electric steamers, steam-bake machines, frying and baking machines, there are often steam generating devices for outputting steam. Currently, common steam generating devices heat all the water in the water tank to generate steam. However, such a design takes a long time to generate steam and cannot achieve the effect of quickly outputting steam. Utility Model Content

[0003] Based on this, it is necessary to provide a steam generating device and a cooking utensil that can quickly generate steam.

[0004] The present application provides a steam generating device, comprising: a water tank, a partition, a heating element and a float valve, wherein the partition is arranged in the water tank, and the partition divides the inner cavity of the water tank into a steam generating cavity and a water storage cavity, the heating element is used to heat the steam generating cavity, a water inlet is arranged on the bottom wall of the steam generating cavity, the float valve is arranged in the steam generating cavity, and can open and close the water inlet according to the water level in the steam generating cavity; a water inlet groove is arranged below the water inlet, and the water inlet groove connects the water storage cavity and the water inlet.

[0005] The steam generating device provided by the present application divides the water tank into a steam generating chamber and a water storage chamber by setting a partition, and steam can be generated by simply heating the water in the steam generating chamber. By setting a float valve, the float valve can open and close the water inlet according to the water level in the steam generating chamber, thereby controlling the amount of water in the steam generating chamber, so that the steam generating chamber can be maintained at a lower water level, thereby generating steam quickly, and at the same time, the steam generating chamber can be replenished with water in time through the water storage chamber to avoid dry burning.

[0006] In one embodiment, the bottom wall of the water inlet groove is lower than the bottom wall of the water storage chamber.

[0007] This is conducive to the water in the water storage chamber flowing into the water inlet tank, thereby replenishing the steam generating chamber with water in time through the water inlet tank.

[0008] In one embodiment, a sealing ring is sleeved inside the water inlet, and the sealing ring at least covers the end surface of the water inlet close to the steam generating chamber, and the float valve cooperates with the sealing ring to close the water inlet.

[0009] In this way, the float valve can well seal the water inlet by pressing against the sealing ring to avoid water leakage at the water inlet, and the sealing ring can play a certain buffering role to reduce the wear caused by the float valve hitting the water inlet.

[0010] In one embodiment, the float valve includes a lever portion, a float provided at one end of the lever portion, and a sealing portion provided at the other end of the lever portion. The lever portion is rotatably installed in the steam generating chamber, the rotation center of the lever portion is provided between the float and the sealing portion, and the sealing portion is provided corresponding to the water inlet.

[0011] In this way, the float valve forms a lever structure. When the water level rises, the float rises, and the sealing part descends and abuts against one end of the water inlet, thereby closing the water inlet; when the water level drops, the float drops, and the sealing part rises and leaves the water inlet, thereby opening the water inlet. The float valve has a simple structure and can timely control the opening and closing of the water inlet according to the water level in the steam generating chamber.

[0012] In one embodiment, the distance between the rotation center of the lever portion and the sealing portion is L1, and the distance between the rotation center of the lever portion and the float is L2, and L1 is smaller than L2.

[0013] In this way, only a smaller buoyancy is needed to control the rotation of the lever part, so that the action of opening and closing the water inlet is more sensitive.

[0014] In one embodiment, the lever portion includes a baffle and a curved rod, the sealing portion is disposed on the baffle, the curved rod is connected to one end of the baffle away from the sealing portion, the float is connected to one end of the curved rod away from the baffle, and when the sealing portion closes the water inlet, the float is higher than the sealing portion.

[0015] In this way, the baffle has a certain shielding effect on the boiling water in the steam generating chamber, thereby reducing the situation where the hot water in the steam generating chamber flows out through the water inlet. The curved rod can make the float higher than the sealing part when the water inlet is closed, so that the water in the steam generating chamber can be maintained at a suitable water level.

[0016] In one embodiment, the bottom wall of the steam generating chamber is provided with a mounting block close to the water inlet, the mounting block is provided with a rotating shaft hole, the lever portion is provided with a rotating shaft, the rotating shaft is located between the float and the sealing portion, and the rotating shaft is rotatably matched with the rotating shaft hole.

[0017] In this way, the float valve can be conveniently installed in the steam generating chamber.

[0018] In one embodiment, the heating element comprises an electric heating plate, and the electric heating plate is arranged at the bottom of the steam generating chamber.

[0019] In this way, the water in the steam generating chamber can be directly heated by the electric heating plate, and the heating efficiency is high.

[0020] In one of the embodiments, the bottom wall of the steam generating chamber includes a hot zone and a cold zone, the electric heating plate is arranged in the hot zone, and the water inlet is arranged in the cold zone.

[0021] In this way, the electric heating plate and the water inlet can be arranged on the bottom wall of the steam generating chamber, and the structure is very compact. In addition, the water inlet is arranged in the cold zone, so that the hot water in the steam generating chamber will not roll violently at the water inlet, thereby reducing the situation where the hot water flows out from the water inlet.

[0022] The present application also provides a cooking appliance, comprising the steam generating device as described above.

[0023] The cooking utensil provided in the present application can generate steam quickly and avoid dry burning by providing the above-mentioned steam generating device. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] See also Figures 1 to 3 The present application provides a steam generating device, comprising: a water tank 10, a partition 20, a heating element 30 and a float valve 40. The partition 20 is arranged in the water tank 10, and the partition 20 divides the inner cavity of the water tank 10 into a steam generating chamber 11 and a water storage chamber 12. The heating element 30 is used to heat the steam generating chamber 11. A water inlet 111 is arranged on the bottom wall of the steam generating chamber 11, and the float valve 40 is arranged in the steam generating chamber 11, and can open and close the water inlet 111 according to the water level in the steam generating chamber 11; a water inlet groove 13 is arranged below the water inlet 111, and the water inlet groove 13 connects the water storage chamber 12 and the water inlet 111. In this way, by setting the partition 20, the water tank 10 is divided into the steam generating chamber 11 and the water storage chamber 12, and steam can be generated by heating the water in the steam generating chamber 11. By setting the float valve 40, the float valve 40 can open and close the water inlet 111 according to the water level in the steam generating chamber 11, so as to control the water amount in the steam generating chamber 11, so that the steam generating chamber 11 can be maintained at a lower water level, so that steam can be generated quickly. At the same time, the steam generating chamber 11 can be replenished with water in time through the water storage chamber 12 to avoid dry burning.

[0038] Furthermore, the bottom wall of the water inlet groove 13 is lower than the bottom wall of the water storage chamber 12, so that the water in the water storage chamber 12 can flow into the water inlet groove 13, thereby timely replenishing the steam generating chamber 11 with water through the water inlet groove 13. In this embodiment, the water inlet groove 13 is formed by partially concavely lowering the bottom wall of the water storage chamber 12, and the structure is simple.

[0039] Furthermore, a sealing ring 112 is sleeved inside the water inlet 111, and the sealing ring 112 at least covers the end surface of the water inlet 111 close to the steam generating chamber 11, and the float valve 40 cooperates with the sealing ring 112 to close the water inlet 111. In this way, the float valve 40 can well seal the water inlet 111 by pressing against the sealing ring 112 to avoid water leakage at the water inlet 111, and the sealing ring 112 can play a certain buffering role to reduce the wear caused by the float valve 40 hitting the water inlet 111. In this embodiment, the sealing ring 112 is sleeved inside the water inlet 111, and both ends of the sealing ring 112 form flanges, which cover the end surfaces of the two ends of the water inlet 111, so that the sealing ring 112 is not easy to fall off from the water inlet 111. Furthermore, the sealing ring 112 is made of silicone material and has a good sealing effect.

[0040] See also Figure 2 and Figure 3 The float valve 40 includes a lever portion 41, a float 42 disposed at one end of the lever portion 41, and a sealing portion 43 disposed at the other end of the lever portion 41. The lever portion 41 is rotatably mounted in the steam generating chamber 11, and the rotation center of the lever portion 41 is disposed between the float 42 and the sealing portion 43. The sealing portion 43 is disposed corresponding to the water inlet 111, so that the water inlet 111 is opened and closed by the sealing portion 43. In this way, the float valve 40 forms a lever structure. When the water level rises, the float 42 rises, and the sealing portion 43 falls and abuts against one end of the water inlet 111, so that the water inlet 111 is closed; when the water level drops, the float 42 drops, and the sealing portion 43 rises and leaves the water inlet 111, so that the water inlet 111 is opened. The float valve 40 has a simple structure and can timely control the opening and closing of the water inlet 111 according to the water level in the steam generating chamber 11.

[0041] In this embodiment, the float 42 is set as a sphere, but it is not limited thereto, and the float 42 can also be any other shape. Further, the float 42 is hollow inside, so that the float 42 is light in weight, which is conducive to its floating on the water surface. In addition, the float 42 can also be filled with light materials, such as plastic foam.

[0042] In this embodiment, the outer surface of the sealing portion 43 is provided with an arc surface, so that the water inlet 111 can be well sealed.

[0043] The distance between the rotation center of the lever part 41 and the sealing part 43 is L1, and the distance between the rotation center of the lever part 41 and the float 42 is L2, and L1 is smaller than L2. In this way, only a small buoyancy is needed to control the rotation of the lever part 41, so that the action of opening and closing the water inlet 111 is more sensitive.

[0044] See also Figures 4 to 6 The lever portion 41 includes a baffle 411 and a curved rod 412. The sealing portion 43 is disposed on the baffle 411. The curved rod 412 is connected to one end of the baffle 411 away from the sealing portion 43. The float 42 is connected to one end of the curved rod 412 away from the baffle 411. When the sealing portion 43 closes the water inlet 111, the float 42 is higher than the sealing portion 43. In this way, the baffle 411 has a certain shielding effect on the boiling water in the steam generating chamber 11, thereby reducing the situation where the hot water in the steam generating chamber 11 flows out through the water inlet 111. The curved rod 412 can make the float 42 higher than the sealing portion 43 when the water inlet 111 is closed, so that the water in the steam generating chamber 11 can be maintained at a suitable water level. In this embodiment, the curved rod 412 is L-shaped, and the curved rod 412 can also be Z-shaped, or other shapes.

[0045] The bottom wall of the steam generation chamber 11 is provided with a mounting block 50 near the water inlet 111. The mounting block 50 is provided with a rotating shaft hole 51. A rotating shaft 44 is provided on the lever portion 41. The rotating shaft 44 is located between the float 42 and the sealing portion 43. The rotating shaft 44 is rotationally engaged with the rotating shaft hole 51, thereby rotatably mounting the float valve 40 on the mounting block 50. In this way, the float valve 40 can be conveniently installed in the steam generation chamber 11. In this embodiment, an opening is provided above the rotating shaft hole 51, and the rotating shaft 44 is inserted into the rotating shaft hole 51 from the opening. The opening can be set to be smaller than the outer diameter of the rotating shaft 44, so as to prevent the rotating shaft 44 from脱出 from the opening. During installation, only need to squeeze the mounting block 50 forcefully to make the opening deform and expand, then the rotating shaft 44 can be inserted into the rotating shaft hole 51. In addition, a limiting member can also be provided at the opening of the rotating shaft hole 51 to limit the rotating shaft 44 from脱出 from the rotating shaft hole 51.

[0046] Please refer to Figure 1 and Figure 4 , the heating member 30 includes an electric hot plate, and the electric hot plate is provided at the bottom of the steam generation chamber 11. In this way, the water in the steam generation chamber 11 can be directly heated by the electric hot plate, and the heating efficiency is high.

[0047] Please refer to Figure 1 and Figure 4 , the bottom wall of the steam generation chamber 11 includes a hot zone 113 and a cold zone 114. The electric hot plate is provided in the hot zone 113, and the water inlet 111 is provided in the cold zone 114. In this way, both the electric hot plate and the water inlet 111 can be provided on the bottom wall of the steam generation chamber 11, and the structure is very compact. And, since the water inlet 111 is provided in the cold zone 114, the hot water in the steam generation chamber 11 will not boil violently at the water inlet 111, thereby reducing the situation of hot water flowing out from the water inlet 111.

[0048] Please refer to Figure 4 as shown, the partition 20 is annular. The steam generation chamber 11 is formed inside the partition 20, and the water storage chamber 12 is formed outside the partition 20. In this way, the temperature inside the water tank 10 is relatively high, while the temperature outside is relatively low. The water storage chamber 12 also plays a role in heat insulation and anti-scalding.

[0049] In this embodiment, the partition 20 includes a circular main body portion 21 and a protruding portion 22 in the shape of a "匚" provided on one side of the main body portion 21. The area enclosed by the main body portion 21 corresponds to the hot zone 113, and the area enclosed by the protruding portion 22 corresponds to the cold zone 114. The water inlet groove 13 is provided below the protruding portion 22. In this way, the structure is very compact. However, it is not limited to this. In other embodiments, the main body portion 21 can also be polygonal, or the partition 20 can be polygonal as a whole. In addition, the partition 20 can also be of any other shape, and the present application does not limit this.

[0050] The partition plate 20 and the water tank 10 may be an integrated structure or a split structure. When the partition plate 20 and the water tank 10 are split structures, a sealing structure may be provided at the connection between the partition plate 20 and the water tank 10 to prevent water leakage.

[0051] See also Figure 1 The present application also provides a cooking appliance, including the steam generating device as described above. In this embodiment, the cooking appliance is an electric steamer, but is not limited thereto. In other embodiments, the cooking appliance may also be a steamer, a steam-bake-in-one machine, a frying-bake machine, or other types of cooking appliances.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
