Description

Technical Field

[0001] The present application relates to the technical field of cooking utensils, and in particular to an electric steamer. Background Art

[0002] Electric steamers are a type of product that people often use in their daily lives. In order to improve the efficiency of steam generation, a steam generation cavity is usually formed directly on the upper surface of a heating plate, and the water above the heating plate is directly heated by the heating plate to generate steam. However, the sealing of the heating plate of this type of electric steamer is usually single-sided, which is prone to seal failure and water leakage after long-term use. Utility Model Content

[0003] Based on this, it is necessary to provide an electric steamer capable of improving the sealing performance of the heating plate.

[0004] An electric steamer comprises a pot body, wherein a heating disk is arranged inside the pot body, and the pot body is provided with an annular baffle corresponding to the heating disk, the baffle is connected to the periphery of the heating disk, and the baffle and the heating disk surround a steam generating chamber, and a positioning portion is arranged at the periphery of the heating disk, the electric steamer also comprises an annular sealing ring, the sealing ring wraps the positioning portion, the baffle is pressed against the upper surface of the sealing ring, and the surface of the sealing ring that is in contact with the positioning portion is provided with a first sealing rib and a second sealing rib, and the first sealing rib and the second sealing rib are respectively abutted against the upper surface and the lower surface of the positioning portion.

[0005] The electric steamer provided in the present application forms a seal on both the upper surface and the lower surface of the positioning portion of the heating plate by arranging a first sealing rib and a second sealing rib, that is, a double-sided seal. When the seal on one side fails, the other side can still play a sealing role, thereby improving the sealing performance of the heating plate, which is beneficial to extending the service life of the electric steamer.

[0006] In one embodiment, a sealing groove is provided on the inner side wall of the sealing ring, and the sealing ring wraps the positioning portion through the sealing groove. The first sealing rib and the second sealing rib are both annular ribs and are respectively provided on opposite side walls of the sealing groove.

[0007] In this way, the sealing ring structure is very simple. During assembly, the sealing ring can be assembled on the positioning portion by simply inserting the positioning portion on the periphery of the heating plate into the sealing groove, thereby achieving the sealing ring wrapping the positioning portion. Since the first sealing rib and the second sealing rib are both annular ribs and are respectively arranged on the opposite side walls of the sealing groove, after the sealing ring is assembled, the first sealing rib and the second sealing rib can abut against the upper surface and the lower surface of the positioning portion, thereby achieving an interference fit between the sealing ring and the positioning portion.

[0008] In one of the embodiments, the baffle at least presses against the upper surface of the inner ring portion of the sealing ring.

[0009] In this way, the inner ring of the sealing ring will not be lifted up due to the baffle pressing the sealing ring too tightly during installation, so that water will not easily penetrate into the sealing groove and will not penetrate under the heating plate, thereby further improving the sealing effect.

[0010] In one of the embodiments, a support member is further provided in the pot body, the support member abuts against the lower surface of the sealing ring, and the support member is at least partially arranged opposite to the baffle.

[0011] In this way, the support member presses the sealing ring from the bottom, and through the cooperation of the baffle and the support member, the sealing ring firmly wraps the upper and lower surfaces of the positioning part, thereby further improving the sealing effect and preventing water from seeping out of the steam generating chamber.

[0012] In one of the embodiments, a stopper is further provided in the pot body, and the stopper abuts against the outer ring side wall of the sealing ring.

[0013] In this way, the sealing ring can be prevented from falling off the positioning portion, ensuring that the sealing ring firmly wraps the positioning portion, thereby further improving the sealing effect.

[0014] In one embodiment, the first sealing rib is disposed close to the notch of the sealing groove, and / or the second sealing rib is disposed close to the bottom of the sealing groove.

[0015] Since the baffle plate and the heating plate enclose a steam generating chamber, if there is a gap between the positioning portion and the sealing ring, the water in the steam generating chamber will enter the gap between the upper surface of the positioning portion and the sealing ring from the notch of the sealing groove. In this embodiment, the first sealing rib is arranged close to the notch of the sealing groove, and a water retaining structure is arranged at the upstream position of the upper surface of the positioning portion, so as to achieve a better sealing effect and prevent water from entering between the sealing groove and the upper surface of the positioning portion. When the first sealing rib fails, water will enter the sealing groove from the upper surface of the positioning portion and flow to the lower surface of the positioning portion. In this embodiment, the second sealing rib is arranged close to the bottom of the sealing groove, and a water retaining structure is arranged at the upstream position of the lower surface of the positioning portion, so as to achieve a better sealing effect and prevent water from flowing out from the lower surface of the positioning portion and entering under the heating plate.

[0016] In one embodiment, the height H1 of the first sealing rib is 0.3 mm to 1.0 mm, and / or the height H2 of the second sealing rib is 0.3 mm to 1.0 mm.

[0017] Thus, the height of the first sealing rib is moderate, and has a good sealing effect. The height of the second sealing rib is moderate, and has a good sealing effect.

[0018] In one embodiment, the number of the first sealing ribs is two, and / or the number of the second sealing ribs is two.

[0019] Thus, when the number of the first sealing ribs is two, the upper surface of the positioning portion forms a double seal, and the sealing effect is better. When the number of the second sealing ribs is two, the lower surface of the positioning portion forms a double seal, and the sealing effect is better.

[0020] In one of the embodiments, a third sealing rib is provided between the sealing ring and the baffle plate, and the third sealing rib is formed on the sealing ring or the baffle plate.

[0021] In this way, a good seal can be formed between the sealing ring and the baffle plate to prevent water from penetrating into the pot body from between the lower surface of the baffle plate and the upper surface of the sealing ring.

[0022] In one embodiment, the height H1 of the third sealing rib is 0.3 mm to 1.0 mm.

[0023] In this way, the height of the third sealing rib is moderate, and a good sealing effect is achieved.

[0024] In one of the embodiments, the heating plate includes a main plate, a heating tube and a heat transfer plate. The heating tube is arranged inside the main plate or on the lower surface of the main plate, and the heat transfer plate is arranged on the upper surface of the main plate. The heat transfer plate protrudes radially from the main plate, and the peripheral portion of the heat transfer plate protruding from the main plate forms the positioning portion.

[0025] In this way, the heating plate is divided into multiple independent components, wherein the heating pipe plays a role of heating, the main plate plays a role of uniform heat, and the heat transfer plate plays a role of heat transfer. The heat transfer plate protrudes radially from the main plate, which is convenient for installing the sealing ring. In addition, the heat transfer plate and the main plate are two independent components that can be made of different materials, which is conducive to reducing material costs and is easier to process.

[0040] See also Figures 1 to 3 The present application provides an electric steamer, comprising a pot body 10, in which a heating plate 20 is arranged. The pot body 10 is provided with an annular baffle 11 corresponding to the heating plate 20, the baffle 11 is connected to the periphery of the heating plate 20, and the baffle 11 and the heating plate 20 surround a steam generating chamber 12. In this way, the heating plate 20 can directly heat the water in the steam generating chamber 12, thereby generating steam, and the heating efficiency is high. A positioning portion 231 is arranged on the periphery of the heating plate 20, and the electric steamer also includes an annular sealing ring 30, the sealing ring 30 wraps the positioning portion 231, and the baffle 11 is pressed against the upper surface of the sealing ring 30. The surface of the sealing ring 30 that fits the positioning portion 231 is provided with a first sealing rib 31 and a second sealing rib 32, and the first sealing rib 31 and the second sealing rib 32 are respectively abutted against the upper surface and the lower surface of the positioning portion 231. In this way, seals are formed on both the upper and lower surfaces of the positioning portion 231 of the heating plate 20, that is, a double-sided seal is formed. When the seal on one side fails, the other side can still play a sealing role, thereby improving the sealing performance of the heating plate 20, which is beneficial to extending the service life of the electric steamer.

[0041] It is understandable that, since the baffle 11 is connected to the periphery of the heating plate 20, the steam generating chamber 12 enclosed by the baffle 11 and the heating plate 20 is smaller than the pot body 10, so that rapid heating can be achieved, thereby generating steam quickly. In order to continuously generate steam, the electric steamer is also provided with a water tank 40, which is connected to the steam generating chamber 12 through a pipeline (not shown), so that the steam generating chamber 12 can be replenished with water through the water tank 40, thereby avoiding the situation of dry burning of the steam generating chamber 12, and ensuring that the electric steamer can continuously generate steam. In addition, a control valve 50 for automatically controlling the water outlet can be provided between the water tank 40 and the steam generating chamber 12, and the control valve 50 automatically replenishes water according to the water amount in the steam generating chamber 12, so that the user only needs to replenish water in the water tank 40, which is very convenient to use.

[0042] See also Figures 2 to 5 The heating plate 20 includes a main plate 21, a heating tube 22 and a heat transfer plate 23. The heating tube 22 is arranged in the main plate 21 or on the lower surface of the main plate 21, and the heat transfer plate 23 is arranged on the upper surface of the main plate 21. The heat transfer plate 23 protrudes radially from the main plate 21, and the peripheral portion of the heat transfer plate 23 protruding from the main plate 21 forms a positioning portion 231. In this way, the heating plate 20 is divided into a plurality of independent components, wherein the heating tube 22 plays a heating role, the main plate 21 plays a heat uniforming role, and the heat transfer plate 23 plays a heat transfer role. The heat transfer plate 23 protrudes radially from the main plate 21, which is convenient for installing the sealing ring 30, and the heat transfer plate 23 and the main plate 21 are two independent components, which can be made of different materials, which is conducive to reducing material costs and is easier to process. The heating tube 22 can be connected to the main plate 21 by casting, and the main plate 21 and the heat transfer plate 23 can be connected by welding, which is not limited in this application.

[0043] Please see 3. Figure 6 and Figure 7 , a sealing groove 33 is provided on the inner side wall of the sealing ring 30, and the sealing ring 30 wraps the positioning portion 231 through the sealing groove 33. The first sealing rib 31 and the second sealing rib 32 are both annular ribs, and are respectively arranged on the opposite side walls of the sealing groove 33. In this way, the structure of the sealing ring 30 is very simple. During assembly, the sealing ring 30 can be assembled on the positioning portion 231 by simply inserting the positioning portion 231 on the periphery of the heating plate 20 into the sealing groove 33, so that the sealing ring 30 wraps the positioning portion 231. Since the first sealing rib 31 and the second sealing rib 32 are both annular ribs, and are respectively arranged on the opposite side walls of the sealing groove 33, after the sealing ring 30 is assembled, the first sealing rib 31 and the second sealing rib 32 can be pressed against the upper surface and the lower surface of the positioning portion 231, so that the sealing ring 30 and the positioning portion 231 are interference fit.

[0044] For further information, see Figure 2 and Figure 3 , the baffle 11 at least presses against the upper surface of the inner ring portion of the sealing ring 30. In this way, the inner ring portion of the sealing ring 30 will not be lifted due to the baffle 11 pressing the sealing ring 30 too tightly during installation, so that water will not easily penetrate into the sealing groove 33, and will not penetrate under the heating plate 20, thereby further improving the sealing effect. In this embodiment, the baffle 11 only presses against the upper surface of the inner ring portion of the sealing ring 30, but it is not limited to this. In other embodiments, the baffle can also press against the entire upper surface of the sealing ring.

[0045] For further information, see Figure 2 and Figure 3 A support member 13 is further provided in the pot body 10, and the support member 13 abuts against the lower surface of the sealing ring 30, and at least a part of the support member 13 is arranged opposite to the baffle 11. In this way, the support member 13 presses the sealing ring 30 from the bottom, and through the cooperation of the baffle 11 and the support member 13, the sealing ring 30 firmly wraps the upper and lower surfaces of the positioning portion 231, thereby further improving the sealing effect and preventing water in the steam generating chamber 12 from leaking out.

[0046] For further information, see Figure 2 and Figure 3 , a stopper 14 is also provided in the pot body 10, and the stopper 14 abuts against the outer side wall of the sealing ring 30. In this way, the sealing ring 30 can be prevented from falling off the positioning portion 231, ensuring that the sealing ring 30 firmly wraps the positioning portion 231, thereby further improving the sealing effect. The stopper 14 can be arranged in a ring shape and surrounded by the outside of the baffle 11; the stopper 14 can also be a plurality of cylinders arranged in a ring shape, as long as the stopper 14 can abut against the outer side wall of the sealing ring 30. In this embodiment, the baffle 11 and the stopper 14 are arranged at intervals, but are not limited to this. In other embodiments, the baffle can also extend to connect with the stopper.

[0047] For further information, see Figure 3 and Figure 7 , the first sealing rib 31 is arranged close to the notch of the sealing groove 33. Since the baffle 11 and the heating plate 20 enclose the steam generating chamber 12, if there is a gap between the positioning portion 231 and the sealing ring 30, water in the steam generating chamber 12 will enter the gap between the upper surface of the positioning portion 231 and the sealing ring 30 from the notch of the sealing groove 33. In this embodiment, the first sealing rib 31 is arranged close to the notch of the sealing groove 33, and a water retaining structure is arranged at the upstream position of the upper surface of the positioning portion 231, so as to achieve a better sealing effect and prevent water from entering between the sealing groove 33 and the upper surface of the positioning portion 231.

[0048] Furthermore, the first sealing rib 31 has a semicircular or arc-shaped outer shape, which has a simple structure and a good sealing effect.

[0049] For further information, see Figure 7 , the height H1 of the first sealing rib 31 is 0.3mm~1.0mm. If the height of the first sealing rib 31 is too small, the first sealing rib 31 is not easy to be close to the upper surface of the positioning part 231, so that it cannot achieve a good sealing effect; if the height of the first sealing rib 31 is too large, the surface of the sealing ring 30 without the first sealing rib 31 is easy to form a gap with the upper surface of the positioning part 231, thereby affecting the sealing effect. In this embodiment, the height H1 of the first sealing rib 31 is 0.3mm~1.0mm, which is moderate in height and has a good sealing effect. In some specific embodiments, the height H1 of the first sealing rib 31 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, or any other value within the range of 0.3mm~1.0mm.

[0050] The number of the first sealing ribs 31 can be one or more, preferably two. When the number of the first sealing ribs 31 is two, a double seal is formed on the upper surface of the positioning portion 231, and the sealing effect is better.

[0051] For further information, see Figure 3 and Figure 7 , the second sealing rib 32 is arranged near the bottom of the sealing groove 33. When the first sealing rib 31 fails, water will enter the sealing groove 33 from the upper surface of the positioning portion 231 and flow to the lower surface of the positioning portion 231. In this embodiment, the second sealing rib 32 is arranged near the bottom of the sealing groove 33, and a water retaining structure is arranged at the upstream position of the lower surface of the positioning portion 231, so as to achieve a better sealing effect and prevent water from flowing out from the lower surface of the positioning portion 231 and entering the bottom of the heating plate 20.

[0052] Furthermore, the second sealing rib 32 has a semicircular or arc-shaped outer shape, which has a simple structure and a good sealing effect.

[0053] For further information, see Figure 7, the height H2 of the second sealing rib 32 is 0.3mm~1.0mm. If the height of the second sealing rib 32 is too small, the second sealing rib 32 is not easy to be close to the lower surface of the positioning part 231, and thus cannot achieve a good sealing effect; if the height of the second sealing rib 32 is too large, the surface of the sealing ring 30 without the second sealing rib 32 is easy to form a gap with the lower surface of the positioning part 231, thereby affecting the sealing effect. In this embodiment, the height H2 of the second sealing rib 32 is 0.3mm~1.0mm, which is moderate in height and has a good sealing effect. In some specific embodiments, the height H2 of the second sealing rib 32 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, or any other value within the range of 0.3mm~1.0mm.

[0054] The number of the second sealing ribs 32 can be one or more, preferably two. When the number of the second sealing ribs 32 is two, a double seal is formed on the lower surface of the positioning portion 231, and the sealing effect is better.

[0055] In this embodiment, the sealing ring 30 is a silicone member with good sealing effect. The first sealing rib 31 and the second sealing rib 32 are both integrally formed on the sealing ring 30 .

[0056] See also Figure 3 A third sealing rib 111 is provided between the sealing ring 30 and the baffle 11, and the third sealing rib 111 is formed on the sealing ring 30 or the baffle 11. In this embodiment, the third sealing rib 111 is formed on the baffle 11, and the upper surface of the sealing ring 30 is a plane. In this way, a good seal can be formed by the cooperation of the third sealing rib 111 and the sealing ring 30, so as to prevent water from penetrating into the pot body 10 from the lower surface of the baffle 11 and the upper surface of the sealing ring 30. Of course, in other embodiments, the third sealing rib can be formed on the sealing ring, and the lower end surface of the baffle is a plane. The cooperation of the third sealing rib and the baffle can also achieve a good sealing effect.

[0057] Furthermore, the third sealing rib 111 has a semicircular or arc-shaped shape, has a simple structure, and has a good sealing effect. In this embodiment, the baffle 11 is made of hard plastic, and the third sealing rib 111 is also made of hard plastic. The third sealing rib 111 and the baffle 11 are an integrally formed structure, so that the baffle 11 can press the sealing ring 30 more tightly, thereby achieving a better seal between the baffle 11 and the heating plate 20.

[0058] Furthermore, the height H3 of the third sealing rib 111 is 0.3 mm to 1.0 mm. If the height of the third sealing rib 111 is too small, the squeezing effect of the third sealing rib 111 on the sealing ring 30 is not good, thereby affecting the sealing effect; if the height of the third sealing rib 111 is too large, a gap is easily formed between the baffle 11 and the sealing ring 30, thereby affecting the sealing effect. In this embodiment, the height H3 of the third sealing rib 111 is 0.3 mm to 1.0 mm, which is moderate in height and has a good sealing effect. In some specific embodiments, the height H3 of the third sealing rib 111 can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, or any other value within the range of 0.3 mm to 1.0 mm.

[0059] The number of the third sealing ribs 111 can be one or more, preferably two. When the number of the third sealing ribs 111 is two, a double seal is formed between the baffle 11 and the sealing ring 30, and the sealing effect is better.

[0060] 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.

[0061] 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.
