The technical solutions of this application will be clearly and completely described below with reference to the drawings.
[0042] Please refer to Figure 1 , in this embodiment, the electric steamer includes a steamer assembly 1 and a cooking cavity 101 located inside the steamer assembly 1. The steamer assembly 1 is provided above the base 102. The base 102 has a water storage cavity 2 inside. A water separation cover 6 is provided in the water storage cavity 2. The water separation cover 6 divides the water storage cavity 2 into an evaporation cavity 201 outside the water separation cover 6 and a secondary heating cavity 202 inside the water separation cover 6. A first heating element 3 for heating the water in the evaporation cavity 201 to generate steam is provided in the electric steamer. A second heating element 4 is provided in the secondary heating cavity 202. The second heating element 4 is used to heat the steam. A steam outlet 602 and a steam inlet 601 are opened on the water separation cover 6. The basic working process of the electric steamer provided in this application is as follows: the water in the evaporation cavity 102 is heated and evaporated by the first heating element 3 to become unsaturated steam. The steam enters the secondary heating cavity 202 from the steam inlet 601 of the water separation cover 6, and after flowing, flows out from the steam outlet 602. Among them, the steam is secondarily heated by the radiation heating or contact heat conduction of the second heating element 4 when entering the secondary heating cavity 202, so as to obtain steam with higher heat, thereby realizing a high-temperature electric steamer. Continue to refer to Figure 1 , the first heating element 3 is provided below the evaporation cavity 201. Of course, the first heating element 3 can also be provided at other positions as long as it can be used to heat the evaporation cavity 201, and no limitation is made here. A partition rib 1021 protrudes inside the base 102. The partition rib 1021 further divides the water storage cavity 2 into a water replenishing cavity 203. A communication part (not shown in the figure) is provided on the partition rib 1021 to connect the water replenishing cavity 203 with the evaporation cavity 201. As the water in the evaporation cavity 201 is heated and evaporated, the water in the water replenishing cavity 203 is replenished into the evaporation cavity 201 from the communication part to ensure its evaporation process. By only heating in the evaporation cavity 201, the area of the evaporation generation area of the electric steamer is restricted, so as to realize the rapid generation of steam. Due to the above scheme, after the steam enters the secondary heating cavity 202 from the steam inlet 601, it is easy to directly flow to the steam outlet 602 and flow out through the gap, resulting in poor secondary heating effect. An improvement scheme is urgently needed to improve the secondary heating effect.
[0043] Please refer to Figure 2 , Figure 2 which is an enlarged schematic view of area A in Figure 1 . The steam outlet 602 is located on one side of the water separation cover 6 close to the cooking cavity 101, and there is no need to limit the position of the steam inlet 601 here. A steam channel is formed from the steam inlet 601 to the steam outlet 602 in the secondary heating cavity 202, and a baffle rib is provided at a position close to the steam outlet 602 in the steam channel. A seal 7 is provided between the steam outlet 602 and the cooking cavity 101. The seal 7 has a steam supply channel 701 for communicating the secondary heating cavity 202 and the cooking cavity 101, and the seal 7 can prevent steam leakage during the process of transporting steam from the secondary heating cavity 202 to the cooking cavity 101. After the steam for secondary heating in the secondary heating cavity 202 flows out from the steam outlet 602, it is transported to the cooking cavity 101 through the connection of the steam supply channel 701 to heat the food placed therein and cook it. The penetration rate of the high-temperature steam after secondary heating to the food is higher, so the heating efficiency and heating uniformity are improved, and the food is more delicious. In one embodiment, the baffle rib can protrude from the water separation cover 6. In another embodiment, refer to Figure 2, the retaining rib 702 protrudes from the seal 7, and at least part of the retaining rib 702 is located within the water shield 6. Regardless of which component the retaining rib protrudes from, since the retaining rib is arranged at a position of the steam channel close to the steam outlet 602, the retaining rib can block the steam from entering the steam supply channel 701 from the steam channel of the secondary heating chamber 202, achieving the effect of delaying the steam flow. That is, an "obstacle" is arranged between the steam channel of the secondary heating chamber 202 and the steam outlet 602, so that the steam generated from the evaporation chamber 202 stays in the secondary heating chamber 202 for a longer time, is heated more fully, the heating temperature of at least part of the output steam is increased, and overall the secondary heating effect is better, solving the problem in the prior art that part of the steam is delivered to the cooking chamber before being secondary heated, resulting in the steam temperature not reaching the expected value. When the retaining rib 702 protrudes from the seal 7, the retaining rib structure and the seal 7 are integrally formed, which is easy to manufacture. When the retaining rib 702 protrudes from the seal 7, there is a gap between the retaining rib 702 and the second heating element 4. This gap enables the retaining rib 702 not to contact the second heating element 4, preventing the second heating element 4 from damaging the retaining rib 702 and thus affecting the normal use of the seal 7, and ensuring that the steam can at least overflow to the steam outlet 602 through this gap at the retaining rib 702, preventing the situation where the steam cannot flow out smoothly and causing the electric steamer to malfunction, and ensuring the service performance of the high-temperature electric steamer. It can be understood that the size of this gap is designed according to the actual needs of parameters such as the space size of the secondary heating chamber, the power of the first heating element 3 and the second heating element 4. The minimum size of the gap satisfies that during the working process of the high-temperature electric steamer, the steam can flow out smoothly without being blocked by the retaining rib 702. There is no limitation on the protruding direction of the retaining rib 702 here, as long as it is ensured that at least part of the retaining rib 702 is located within the water shield 6, blocking the steam in the secondary heating chamber 202 during the working process and delaying at least part of the steam from directly flowing out of the steam outlet 602 in the secondary heating chamber 202, thus playing the role of improving the secondary heating effect of the steam. In other embodiments, the retaining rib can contact the second heating element 4, as long as it is ensured that the heat-resistant temperature of the retaining rib is greater than or equal to the highest temperature in the working state of the second heating element 4, and there is no limitation here.
[0044] Specifically, the retaining rib protrudes at the rim of the steam outlet 602, that is, protrudes at the end of the steam channel. Please refer to Figure 2, when the retaining rib protrudes from the seal 7, the retaining rib 702 protrudes at the edge of the steam outlet 602. The edge of the steam outlet 602 is located at the initial end of the steam supply channel 701 close to the secondary heating chamber 202. Therefore, by arranging the retaining rib here, the retaining rib is almost entirely located within the water isolation cover 6, that is, almost entirely within the secondary heating chamber 202, which can block steam to a greater extent and delay the moment of its outflow. As a result, the steam is heated by the second heating element 4 for a longer time, making the heat and / or temperature of the obtained steam higher, and making the heating uniformity of the heated food better and the cooking faster, greatly improving the cooking efficiency. Combining Figure 3 it can be seen that the retaining rib 702 extends in the vertical direction, and / or the retaining rib 702 extends obliquely inward towards the steam outlet 602. When the retaining rib protrudes from other components, the above two extension structures can also be achieved. When the retaining rib 702 extends vertically downward, the overall shape of the seal 7 is simple and easy to manufacture. When installing the seal 7, it is not easily blocked due to additional structures, and the assembly is smooth, providing a good user experience. When the retaining rib 702 extends obliquely inward towards the steam outlet 602, the moment when the steam entering the secondary heating chamber 202 from the steam inlet 601 encounters the retaining rib 702 is delayed. After encountering the retaining rib 702 that slopes inward towards the steam outlet 602, it continues to move along the inclined surface of the retaining rib 702, and then flows through the gap below to the steam outlet 602 after moving below the retaining rib 702. This can lengthen the movement path of the steam in the secondary heating chamber 202, enabling it to be fully heated, and also making the steam more concentrated in the middle of the steam outlet 602, redistributing the steam when it flows in the steam supply channel and improving the steam outlet uniformity. When the above two structures are used simultaneously, that is, when there are multiple different retaining rib structures, a certain degree of flow-around is formed at the steam outlet 602, further improving the steam outlet uniformity. It can be known that the retaining rib 702 can also protrude in other directions, as long as it can block the steam between the steam outlet 602 and the second heating element 4, and in Figure 2 and Figure 3 the schematic illustration, the retaining rib protrudes from the seal 7. In other embodiments, the retaining rib can also protrude from other components, such as the water isolation cover 6. The above solutions can be implemented after being read by those skilled in the art, and are not limited here.
[0045] In one embodiment, when the retaining rib 702 protrudes from the seal 7, the retaining rib 702 is elastic. In the vertical direction, the lower end of the retaining rib 702 is higher than the top surface of the second heating element 4. The advantage is that when the retaining rib 702 blocks sufficient steam on the side away from the steam outlet 602, sufficient pressure is formed, and the steam squeezes and flips the elastic retaining rib 702 towards the inside of the steam outlet 602. At this time, the gap between the retaining rib 702 and the second heating element 4 becomes larger, and the steam that has been sufficiently reheated by the second heating element 4 flows out from this gap, flows towards the steam outlet 602, and then flows into the steam supply channel 701 to supply steam to the cooking cavity 101, ensuring smooth steam transportation. In addition, the lower end of the retaining rib 702 being higher than the top surface of the second heating element 4 ensures that the retaining rib 702 can be smoothly flipped when squeezed by a sufficient amount of steam, without being obstructed by the second heating element 4 during the flipping process. The elastic characteristic enables the retaining rib 702 to reset and continue to work after a certain amount of steam has flowed out, ensuring the smooth outflow of steam and the normal operation of the electric steamer. The elasticity of the retaining rib 702 can be achieved by using an elastic material or by setting an elastic member between the retaining rib 702 and the inner wall of the water shield 6, and no limitation is made here.
[0046] Please refer to Figure 7 , in this embodiment, the retaining rib 702 protrudes from the seal 7, and the retaining rib 702 protrudes from the inner wall 7011 of the steam supply channel 701. Specifically, it extends obliquely towards the inside of the steam outlet 602. It can be understood that the initial end of the protrusion of the retaining rib 702 is on the inner wall 7011, and the end of the protrusion extends into the water shield 6. The retaining rib 702 extends into the water shield 6 to ensure that the steam is delayed from overflowing from the secondary heating cavity 202, so as to ensure the secondary heating effect of the steam, rather than just delaying its overflow from the steam supply channel 701. The steam entering the steam supply channel 701 is blocked, and at least part of the steam is blocked back to the secondary heating cavity 202 or flows back to the secondary heating cavity 202 along the boundary of the retaining rib 702 for secondary heating again, ensuring the secondary heating effect. And setting the retaining rib 702 in the steam supply channel 701 can reduce the flow cross-sectional area in the channel. According to Bernoulli's principle, the flow velocity of the steam can be increased to a certain extent, thereby increasing the steam outlet velocity. As the steam outlet velocity increases, the steam will be more likely to spread throughout the cooking cavity 101, resulting in good steam uniformity and thus improving the heating effect on food. Similarly, the retaining rib provided at the position of the steam channel close to the steam outlet 602 can play a role in increasing the flow velocity. In other embodiments, the shape of the retaining rib 702 may not extend obliquely towards the inside of the steam outlet 602, as long as at least part of the retaining rib 702 is located inside the water shield 6.
[0047] The retaining rib extends obliquely towards the outside of the water shield 6. Please refer to Figure 4, in this embodiment, the baffle rib 702 extends obliquely towards the outside of the water isolation cover 6. When the steam flows to the baffle rib 702, a part of the steam flows into the outside of the baffle rib 702, and this part of the steam is delayed from flowing towards the steam outlet 602. The heat of this part of the steam is increased by the heating of the second heating element 4, and the secondary heating effect is generally improved. Further, the lower end of the baffle rib 702 is lower than the top surface of the second heating element 4 in the vertical direction, so that the space outside the baffle rib 702 becomes larger, and the amount of steam that can be retained becomes more, further improving the secondary heating effect.
[0048] Please refer to Figure 8 , in this embodiment, at least two different baffle rib structures are adopted, an outer baffle rib 702a protruding from the edge of the steam outlet 602, and an inner baffle rib 702b protruding from the inner wall 7011 of the steam supply channel 701. The combination of the two baffle ribs forms a further blocking structure at the steam outlet 602 to the inside of the steam supply channel 701, delaying the outflow of the steam, so that the heating time of the steam in the secondary heating chamber 202 is increased, and the heat possessed by the outflowing steam is ensured. Among them, the inner baffle rib 702b needs to protrude from the seal 7, and there is no restriction on the protruding position of the outer baffle rib, that is, it can protrude from the seal 7, or it can protrude from the water isolation cover 6 or other components, as long as the aforementioned blocking structure can be formed.
[0049] In a preferred embodiment, the baffle ribs are continuous in the circumferential direction of the steam outlet 602. Therefore, the baffle ribs only have one baffle rib structure at one position, reducing the manufacturing difficulty of the seal 7. The continuity of the baffle ribs can make their blocking effect reach the best, ensuring the delayed outflow of the steam, keeping the steam in the secondary heating chamber 202 longer, and ensuring its secondary heating effect. In addition, the channel area at the end of the steam outlet channel 802 or the initial end of the steam supply channel 701 becomes narrower. Under the condition of constant flow rate, the speed of the steam leaving the channel can be increased. The increase in the steam outlet speed can make the steam uniformity in the cooking chamber 101 better. When the baffle ribs adopt a continuous circumferential structure, since the steam stays in the secondary heating chamber 202 for a longer time and the amount of accumulated steam becomes more, the steam pressure potential energy here is higher than that of the existing technology solution, forming a micro-pressure chamber. When the pressure increases, the saturation temperature that the steam can reach is higher, and it is easier to obtain superheated steam. Therefore, the outlet steam temperature obtained can be higher, and the higher temperature steam has a better heating effect on the food materials, realizing a good high-temperature electric steam cooker. In addition, when the baffle rib 702 protrudes from the seal 7, the continuously arranged baffle rib 702 is easier to manufacture, reducing the requirements for the mold, and the demolding of the seal 7 is also simpler, reducing the production cost of the seal 7. In the case of damage to the seal 7, the user can replace it at a lower price, ensuring the use of the high-temperature electric steam cooker.
[0050] Please refer to Figure 2 、Figure 7 and Figure 8 , at least one hole portion 7021 is formed below the retaining rib 702. The shape of the hole portion 7021 is not limited herein. The hole portion 7021 guides the steam, generates a jet effect, and improves the steam outlet speed. Further, when the retaining rib 702 is continuous along the circumferential direction of the steam outlet 602, providing one hole portion 7021 below the retaining rib 702 can not only release the steam in time and increase the outlet speed, ensuring the pressure safety in the secondary heating chamber 202, but also does not require a gap between the retaining rib and the second heating member 4 or an increase in the size of the gap to ensure safety, thereby ensuring the blocking effect of the retaining rib on the steam between the steam outlet 602 and the second heating member 4, and achieving a high-temperature electric steam cooker with good secondary heating effect of the present utility model.
[0051] Please refer to Figure 8 , in one embodiment, two types of retaining rib structures are adopted, respectively protruding at the rim of the steam outlet 602 and protruding from the inner wall 7011 of the steam supply channel 701 towards the second heating member 4. Here, only the inner retaining rib 702b is provided with the hole portion 7021. After the steam is blocked by the outer retaining rib 702a in the secondary heating chamber 202, it bypasses the outer retaining rib 702a and enters below the inner retaining rib 702b, and is concentrated and flows into the steam supply channel 701 through the guidance of the hole portion 7021, achieving the effect of concentrating the steam, increasing the steam output and the steam outlet rate, and making the steam uniformity in the cooking chamber 101 better.
[0052] Please refer to Figures 1 to 8 , in one embodiment, the high-temperature electric steam cooker further includes a juice receiving tray 5 located between the water storage chamber 2 and the cooking chamber 101. The juice receiving tray 5 is provided with a through hole communicating with the water storage chamber 2. Specifically, the through hole communicates with the steam outlet 602. Since the secondary heating chamber 202 and the cooking chamber 101 are communicated through the steam supply channel 701, one end of the seal member 7 close to the cooking chamber 101 is hermetically connected to the through hole of the juice receiving tray 5, and the juice receiving tray 5 is only communicated with the secondary heating chamber 202 through the sealed portion of the seal member 7, preventing the steam in the evaporation chamber 201 of the water storage chamber 2 from entering the cooking chamber 101 before entering the secondary heating chamber 202 and ensuring the generation of high-temperature steam. A heat conducting cover 8 is further provided in the secondary heating chamber 202. Therefore, the retaining rib can also protrude from the heat conducting cover 8, as long as it is ensured that the position of the retaining rib is located at a position of the steam channel close to the steam outlet 602. The upper end of the heat conducting cover 8 is connected to the water separating cover 6 at a position between the steam inlet 601 and the steam outlet 602. The second heating member 4 is also used to heat the heat conducting cover 8. Refer to Figure 3, the heat conduction cover 8 divides the aforementioned steam channel into a steam inlet channel 801 between the water separation cover 6 and the heat conduction cover 8 and a steam outlet channel 802 between the heat conduction cover 8 and the second heating element 4. At this time, the rib is located at a position of the steam outlet channel 802 close to the steam outlet 602. The heat transfer through the heat conduction cover 8 first heats the steam entering the steam inlet channel 801 from the steam inlet 601. Continue to refer to Figure 3 , the steam inlet channel 801 bypasses the lower end of the heat conduction cover 8 and communicates with the steam outlet channel 802. The steam outlet 602 penetrates through the top of the heat conduction cover 8 and the water separation cover 6 and communicates with the steam outlet channel 802. Since the steam outlet 602 is located on the side close to the cooking cavity 101, the steam flow forms a path that enters the secondary heating cavity 202 from the steam inlet 601, flows along the steam inlet channel 801 to the lower part of the heat conduction cover 8, then enters the steam outlet channel 802, and flows upward along the steam outlet channel 802 to the steam outlet 602, forming a winding flow. The advantage is that the flow path is extended. The setting of the heat conduction cover 8 greatly prolongs the heating time of the steam in the secondary heating cavity 202 and improves the secondary heating effect. With the rib provided in the present invention, the secondary heating effect is better.
[0053] Refer to Figure 2 , both the steam inlet 601 and the steam outlet 602 are opened on the top wall of the water separation cover 6, so as to further lengthen the flow path of the steam in the secondary heating cavity 202 to a greater extent. Refer to Figure 5, the steam inlet 601 is located on the outer periphery of the steam outlet 602. A flanging 603 is provided at the edge of the steam outlet 602 to form a sealed connection part connecting the heat conduction cover 8 and the water separation cover 6. The sealed connection part includes a fixing groove 604 formed by bending and extending the flanging 603. The heat conduction cover 8 is provided with an opening corresponding to the steam outlet 602, and the edge of the opening extends into the fixing groove 604 for fitting and fixing. In this embodiment, the edge of the steam outlet 602 is folded into the fixing groove 604. After the opening of the heat conduction cover 8 is fitted with the fixing groove 604, the two are fixed by pressing. This can make the fixing of the two relatively simple and convenient, with a high fixing strength and good sealing performance at the fixing part, so as to form a double seal for the secondary heating cavity 202 with the seal 7, ensuring no steam leakage. Moreover, the steam inlet channel 801 and the steam outlet channel 802 can be well separated, preventing the steam entering from the steam inlet 601 from directly entering the steam outlet channel 802 and overflowing from the steam outlet 602, ensuring the residence of steam in the secondary heating cavity 202 and its secondary heating effect, and achieving a better secondary heating effect in cooperation with the rib. The flanging 603 can also make the edge of the steam outlet 602 more round and smooth, reducing the wear on the seal 7 and preventing it from being scratched, and making it more smooth to install the seal 7 and convenient for assembly. The steam inlets 601 are arranged at intervals around the outer periphery of the steam outlet 602. Compared with continuous arrangement, the interval arrangement can reduce the steam inlet volume to ensure the heating effect of steam in the secondary heating cavity. Preferably, the seal 7 is a silica gel part or a rubber part to ensure the sealing effect of the seal 7. Preferably, both the water separation cover 6 and the heat conduction cover 8 are hardware parts. They are assembled by the above pressing method, reducing the assembly difficulty, improving the assembly strength, and the use of hardware parts ensures the structural strength of the secondary heating cavity, ensuring the smooth progress of its secondary heating, improving the secondary heating effect and the service life of the high-temperature electric steamer provided by the present utility model.
[0054] Continue to refer to Figure 2 , both the steam inlet 601 and the steam outlet 602 are opened on the top wall of the water separation cover 6. The bottom of the heat conduction cover 8 has a steam passage 803 connecting the steam inlet channel 801 and the steam outlet channel 802. Refer to Figure 6 , the second heating element 4 is provided with radially protruding heating protrusions 401 at intervals along its circumferential direction. The steam outlet channels 802 are formed between two adjacent heating protrusions 401. Designed in this way, the contact area between the second heating element 4 and the steam can be increased to improve the heating rate of the steam.
[0055] Specifically, refer to Figure 2, in this embodiment, an installation boss 9 is provided in the evaporation chamber 201, and the second heating element 4 is arranged on the installation boss 9. The second heating element 4 can be fixed to the installation boss 9 through fixing screws 901. The second heating element 4 is lifted by a certain height through the installation boss 9 so that it cannot contact the water at the bottom of the evaporation chamber 201, thereby avoiding directly heating the water by the second heating element 4 and ensuring that the second heating element 4 heats the steam. The water isolation cover 6 is fixed by an interference fit with the sealing ring 10, reducing the installation and disassembly difficulty of the water isolation cover 6. At the same time, the sealing is ensured to prevent the water in the evaporation chamber 201 from flowing into the secondary heating chamber 202.
