Description

Technical Field

[0001] The utility model belongs to the technical field of electric steamers, and particularly relates to a three-dimensional steam circulation electric steamer. Background Art

[0002] An electric steamer, also called an electric steamer basket, is a kitchen household appliance developed on the basis of traditional wooden steamers, aluminum steamers, bamboo steamers, etc., which directly steams various delicacies by using the principle of electric heating steam. However, at present, the steam of electric steamers on the market generally discharges water vapor from bottom to top. Most of the water vapor contacts the bottom surface of the food to heat the food. Only a small amount of water vapor can flow upward through the bottom of the food to the top and side positions of the food to heat the top and side of the food under the blockage of the bottom of the food. Therefore, the food cannot be quickly steamed. In addition, when the food is unevenly heated on each side, it is easy to cause part of the food to be cooked while the other part is not cooked, affecting the steaming effect. Content of the Utility Model

[0003] (I) Purpose of the Utility Model

[0004] In order to overcome the above deficiencies, the purpose of the present utility model is to provide a three-dimensional steam circulation electric steamer to solve the technical problems that the existing electric steamer cannot quickly heat and steam food and has poor steaming effect.

[0005] (II) Technical Solution

[0006] To achieve the above purpose, the technical solution provided by the present application is as follows:

[0007] A three-dimensional steam circulation electric steamer includes: a water tank steam chamber for containing water and heating the water, a steaming plate arranged above the water tank steam chamber for placing food materials, with a plurality of first ventilation holes formed thereon, a steamer basket covering the steaming plate, a diversion seat arranged inside the steamer basket, the diversion seat being a hollow structure and having a plurality of second ventilation holes, and further including: a steam concentrating cover arranged in the water tank steam chamber, wherein the lower end of the steam concentrating cover covers a partial area of the bottom of the water tank steam chamber, and the upper end passes through the steaming plate and extends into the diversion seat, and can divert a part of the water vapor into the diversion seat after the water in the water tank steam chamber is heated to form water vapor, so that the water vapor can be discharged onto the upper surface of the food through the second ventilation holes for heating, and another part of the water vapor in the water tank steam chamber is discharged onto the lower surface of the food materials through the first through holes of the steaming plate for heating;

[0008] In this application, by providing a steam concentrating cover, a part of the water vapor generated in the water tank steam chamber can be guided into the diversion base, and then discharged through the second ventilation holes of the diversion base to the top and side surfaces of the food to heat the food. At the same time, another part of the water vapor in the water tank steam chamber is directly discharged through the first through holes of the steaming plate to the lower surface of the food material to heat its bottom surface. Therefore, the water vapor can heat the food three-dimensionally from above, below, and on the side, quickly steaming the food, making the food evenly heated, and ensuring the steaming effect of the food.

[0009] In some embodiments, the steam concentrating cover includes a concentrating base for collecting a part of the water vapor, which covers a part of the bottom area of the water tank steam chamber, and at least one diversion channel that communicates with the concentrating base and extends into the diversion base.

[0010] In some embodiments, it further includes: a diversion partition provided in the diversion base that can divide the diversion base into an upper diversion steam chamber and a lower diversion steam chamber. The lower diversion steam chamber communicates with the second ventilation holes. A third ventilation hole is provided at a position corresponding to the second ventilation holes on the diversion partition. It also includes a fan rotatably provided in the upper diversion steam chamber. Among them, one diversion channel of the steam concentrating cover extends into the lower diversion steam chamber to discharge the water vapor into the lower diversion steam chamber, and the other diversion channel extends into the upper diversion steam chamber, where the water vapor will push the fan to rotate, so that the water vapor in the lower diversion steam chamber can be forced to be discharged through the connection with the second ventilation holes;

[0011] By providing a diversion partition to divide the inside of the diversion base into two parts, and a fan is provided in the upper diversion steam chamber. A part of the water vapor is discharged into the upper diversion steam chamber to push the fan to rotate, and the other part of the water vapor is discharged into the lower diversion steam chamber. When the wind generated by the rotation of the fan blows into the lower diversion steam chamber through the third ventilation hole, it forces the water vapor in the lower diversion steam chamber to continuously discharge from the second ventilation holes to contact and heat the top and side surfaces of the food. In this way, a negative pressure will be formed in the lower diversion steam chamber, and the water vapor generated at the bottom of the water tank steam chamber will continuously enter the steam concentrating cover and then flow into the upper diversion steam chamber, forming a continuous cycle process, which can continuously discharge water vapor to heat the top and side surfaces of the food, further ensuring the steaming effect.

[0012] In some embodiments, at positions corresponding to the diversion channels on the diversion base, a plurality of connection channels are formed extending downward to dock with the diversion channels.

[0013] In some embodiments, an exhaust port is formed at the upper end of the diversion channel, and a collection cavity for collecting the condensed water formed after the liquefaction of the water vapor is formed by concave downward around the exhaust port. Among them, the lower end of the connection channel is sleeved outside the exhaust port, and a gap for the condensed water to flow through and enter the collection cavity is formed between the lower end of the connection channel and the outer wall of the exhaust port;

[0014] When water vapor flows upward along the diversion channel and the connection channel and contacts the inner side wall of the connection channel, it will cool down to form condensed water. Then, the condensed water flows downward and can enter the collection cavity, sealing the gap between the diversion channel and the connection channel, preventing water vapor from overflowing from the gap, which would otherwise reduce the amount of water vapor flowing upward into the lower steam chamber and the water vapor discharged from the gap would disrupt the direction of the water vapor flowing downward from the lower steam chamber. Moreover, compared with using materials such as sealing rings to seal the gap between the diversion channel and the connection channel, using condensed water for sealing does not require consuming materials, is more environmentally friendly, and can avoid particulate contamination of food caused by the shedding of aged sealing rings and other materials.

[0015] In some embodiments, the side wall of the exhaust port narrows towards the center to form a guiding inclined surface for guiding the condensed water into the collection cavity;

[0016] Optimize the shape of the exhaust port so that the condensed water can quickly and in large quantities enter the collection cavity along the guiding inclined surface, achieving a quick and good sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0032] Please refer to Figures 1 - 3 , Figure 8 , 10 and Figure 11 , a steam three-dimensional circulation electric steamer provided by the present utility model includes: a water tank steam chamber 1 for containing water and heating the water, a steaming plate 3 arranged above the water tank steam chamber 1 for placing food materials, on which a plurality of first ventilation holes 301 are opened, a steamer 4 covering above the steaming plate 3, a flow guide seat 5 arranged inside the steamer 4, the flow guide seat 5 being a hollow structure and having a plurality of second ventilation holes 502, and further including: a steam energy-gathering cover 2 arranged in the water tank steam chamber 1, wherein the lower end of the steam energy-gathering cover 2 covers a partial area at the bottom of the water tank steam chamber 1, and the upper end passes through the steaming plate 3 and extends into the flow guide seat 5, and can guide a part of the water vapor into the flow guide seat 5 after the water in the water tank steam chamber 1 is heated to form water vapor, so that the water vapor can be discharged to the upper surface of the food through the second ventilation holes 502 for heating, and another part of the water vapor in the water tank steam chamber 1 is discharged to the lower surface of the food materials through the first through holes 302 of the steaming plate 3 for heating.

[0033] Specifically, a heating component 9 is provided at the bottom of the water tank steam chamber 1. During the steaming process, water needs to be added into the water tank steam chamber 1. The lower end of the steam concentrating cover 2 covers a part of the area at the bottom of the water tank steam chamber 1, and the other part of the water is outside the steam concentrating cover 2. When the heating component 9 is started, the water in the water tank steam chamber 1 is heated to boiling to generate water vapor. A part of the water vapor enters the diversion seat 5 and flows along the diversion seat 5, and finally is discharged from the second ventilation hole 502 of the diversion seat 5 to heat the top surface and the side surface of the food. At the same time, another part of the water vapor in the water tank steam chamber 1 is directly discharged through the first through hole 302 of the steaming plate 3 to contact the lower surface of the food material to heat its bottom surface. The water vapor of the electric steamer in this application can perform three-dimensional heating on the food from above, below and on the side, can quickly steam the food, and can make each side of the food evenly heated, ensuring the steaming effect of the food.

[0034] Specifically, the steam concentrating cover 2 includes a concentrating base 201 and at least one diversion channel 202 communicated with the concentrating base 201. The concentrating base 201 of the water vapor covers a part of the area at the bottom of the water tank steam chamber 1, and the diversion channel 202 extends upward into the diversion seat 5.

[0035] Specifically, the steaming plate 3 is directly placed on the top of the water tank steam chamber 1. Through holes 302 are formed on the steaming plate 3 for the diversion channels 202 to pass through and extend upward. Specifically, the diameter of the through hole 302 can be set to match the diameter of the diversion channel 202, and they are engaged with each other by interference fit. In this way, the steaming plate 3 can suspend the steam concentrating cover 2, so that a tiny gap for water to flow in can be formed between the concentrating base 201 of the steam concentrating cover 2 and the bottom of the water tank steam chamber 1.

[0036] Specifically, the diversion seat 5 is embedded in the top position inside the steamer basket 4. A diversion upper cover 8 is provided on the diversion seat 5 to seal the diversion seat 5.

[0037] Please refer to Figures 4 - 7 , preferably, a diversion partition 7 is provided in the diversion seat 5 in this application. The diversion partition 7 divides the diversion seat 5 into a diversion upper steam chamber and a diversion lower steam chamber. The diversion lower steam chamber is communicated with the second ventilation hole 502. A first air guide cover 503 is provided on the lower steam chamber. A third ventilation hole 702 is formed on the diversion partition 7 at the position corresponding to the second ventilation hole 502. A second air guide cover 701 is provided on the diversion partition 7 corresponding to the third ventilation hole 702. And a fan 6 is provided at the position corresponding to the second air guide cover 701 in the upper steam chamber. In this embodiment, there are two diversion channels 202. One of the diversion channels 202 extends to the diversion lower steam chamber and is communicated with the first air guide cover 503 to discharge the water vapor into the diversion lower steam chamber, and the other diversion channel 202 extends into the diversion upper steam chamber and is communicated with the second air guide cover 701.

[0038] Specifically, when water vapor is discharged into the upper steam chamber, it can push the fan 6 to rotate. The wind generated by the rotation of the fan 6 blows into the lower steam chamber through the third ventilation hole 702, forcing the water vapor in the lower steam chamber to continuously discharge from the second ventilation hole 502 and contact the top and side surfaces of the food to heat it. In this way, a negative pressure will be formed in the lower steam chamber, and the water vapor in the water tank steam chamber 1 will continuously enter the steam energy-gathering cover 2 and then flow upward into the diversion upper steam chamber and the diversion upper steam chamber, forming a continuous circulation process, and can continuously heat the top and side surfaces of the food to further ensure the steaming effect.

[0039] Specifically, at the position corresponding to the diversion channel 202 on the diversion seat 5, a plurality of connection channels 501 that are docked with the diversion channel 202 extend downward.

[0040] Please refer to Figure 8 、 9 and Figure 12 Preferably, the shape of the diversion channel 202 of the steam energy-gathering cover 2 of the present application is optimized. An exhaust port 203 is formed at the upper end of the diversion channel 202, and then a collection cavity 204 is recessed downward around the exhaust port 203. The lower end of the connection channel 501 is sleeved outside the exhaust port 203 and a gap is formed between the lower end of the connection channel 501 and the outer side wall of the exhaust port 203. When the water vapor flows upward along the diversion channel 202 and the connection channel 501 and contacts the inner side wall of the connection channel 501, it will cool down to form condensed water, and then the condensed water flows downward into the collection cavity 204. The condensed water can seal the gap between the diversion channel 202 and the connection channel 501.

[0041] Furthermore, the side wall of the exhaust port 203 of the present application is narrowed toward the center direction to form a guiding inclined surface 205 for guiding the condensed water to the collection cavity 204.

[0042] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modification examples that fall within the scope and boundary of the appended claims, or equivalent forms of such scope and boundary.
