detailed description

Embodiments provided by the present invention are described below in conjunction with the accompanying drawings. In this document, the "up" and "down" orientation words used are determined with reference to the use status of the instant steamer.

Please refer to Fig. 1 and Fig. 2, Fig. 1 is a sectional view of the instant steam pot provided by the embodiment of the present invention, and at the same time illustrates the working principle of the instant steam pot. Fig. 2 is an exploded view of the instant steam pot provided by the embodiment, showing various components of the instant steam pot. The instant steam pot provided by the embodiment of the present invention includes a pot lower body 100 and a pot upper body 200 .

The pot upper body 200 includes an upper shell 201 , a cover 202 and a steaming rack 203 . The lid 202 cooperates with the upper opening of the upper casing 201, and a steam heating cavity 210 is formed inside, for placing or containing food ingredients to be steamed. The periphery of the lower bottom plate of the upper casing 201 is closed, and the middle part forms a penetrating part corresponding to the steam output port 112 of the steam forming chamber 110 described later, so that steam enters the steam heating chamber 210 . For steaming needs, in this embodiment, the inner wall of the upper casing 201 also forms a supporting step. The pot upper body 200 also includes a steaming rack 203 matched with the supporting steps to place food materials that need to be steamed.

In this embodiment, the pot lower body 100 includes a lower shell 101 and a separation ring 102 . The lower housing 101 includes an annular plate, and the dividing ring 102 is located in the middle of the annular plate. The lower ends of the annular plate and the dividing ring 102 are closed by an annular bottom plate. The upper part of the annular bottom plate forms a water storage chamber 120 for storing backup water. The upper opening of the water storage chamber 120 is opposite to the peripheral closed portion of the bottom plate of the upper casing 201 , covering the upper opening of the water storage chamber 120 . The lower part of the separating ring 102 is closed by the heating plate 111, and the upper part of the heating plate 111 forms a steam forming chamber 110 for generating steam. The upper opening of the steam forming chamber 110 is opposite to the through part of the middle part of the bottom plate of the upper casing 201 to output the generated steam.

In this embodiment, the bottom surface of the water storage chamber 120 is substantially equal in height to the bottom surface of the steam generating chamber 110 . A water filling port 121 communicating with the inside and the outside is also provided near the bottom edge of the partition ring 102 . The water supply port 121 is located between the water storage chamber 120 and the steam generating chamber 110 and communicates the two.

When in use, an appropriate amount of water is added to the water storage chamber 120 and the steam generation chamber 110 , and the water level in the water storage chamber 120 is kept equal to the water level in the steam generation chamber 110 due to the connection of the water supply port 121 . The water filling port 121 is close to the bottom, lower than the steam output port 112, and lower than the predetermined water storage level of the water storage cavity 120, and the height difference is H. The water level of the water storage chamber 120 and the water level of the steam generating chamber 110 can maintain a water seal to the water replenishment port 121 .

Then, the heat receiving plate 111 at the lower part of the steam forming chamber 110 can be heated by a heat source or a heating device (such as an external liquefied gas stove), so that the water in the steam forming chamber 110 boils to form steam. The formed steam reaches steam through the steam output port 112 of the steam forming chamber 110 . But when the pressure is abnormal (such as opening or closing the lid 202 halfway), in order to prevent the water in the steam forming chamber 110 from flowing out backwards, ensure the temperature of the steam forming chamber 110, and then keep the water in the steam forming chamber 110 boiling, the water supply port 121 can be A one-way valve plate is provided that leads from the water storage chamber 120 to the steam forming chamber 110 to ensure smooth replenishment of water and reduce the outward flow of the steam forming chamber 110 .

In the embodiment shown in the figure, the water storage chamber 120 and the steam generation chamber 110 are separated by an annular partition ring 102 , and the water storage chamber 120 has an annular structure surrounding the outer periphery of the steam generation chamber 110 . In this way, the water storage chamber 120 can absorb the radiant heat of the steam forming chamber 110, and then on the one hand play a function of preheating the water in the water storage chamber 120 or the supplemented water, thereby helping to ensure the continuous boiling of the steam forming chamber 110; On the one hand, it can reduce heat waste and improve energy saving effect.

In another embodiment, in order to better "separate" the water storage chamber 120 and the steam formation chamber 110, avoid the steam formation chamber 110 from transferring too much heat to the water storage chamber 120, ensure the temperature of the steam formation chamber 110, and keep the steam formation chamber 110 Continuous boiling, the separation ring 102 can be set to a double-layer vacuum structure, that is, the separation ring 102 includes an inner layer and an outer layer, and the inner layer and the outer layer are evacuated, thereby reducing the heat transfer from the steam forming chamber 110 to the storage tank through "conduction". Water chamber 120. Further, in order to reduce heat transfer to the water storage chamber 120 through "radiation", the inner surface of the outer layer of the separation ring 102 can be set as a reflective surface, and the outer surface of the inner layer can be set to have a certain roughness or a black surface to absorb reflection radiant heat back.

Certainly, in the case that the separation ring 102 has a double-layer vacuum structure, the water supply port 121 may be formed by a pipe passing through the double-layer vacuum structure. In order to preheat the water entering the steam forming chamber 110 through the water filling port 121, a preheating channel extending along the circumferential direction for a predetermined distance can be set in the inner layer of the separation ring 102, so that the added water can enter the steam after passing through the preheating channel. In the forming chamber 110, the temperature of the water added into the steam forming chamber 110 is increased to ensure that the steam forming chamber 110 continues to boil.

It can be understood that an instant steam pot may include multiple water storage chambers 120 , and the multiple water storage chambers 120 are located on the outer periphery of the steam forming chamber 110 .

As shown in FIG. 1 and FIG. 2 , at least a part of the lateral cross-sectional area of the steam forming chamber 110 sends the formed steam from the lower heating chamber 210 to the steam heating chamber 210 to heat and steam the food materials. Since only the water in the steam forming chamber 110 needs to be heated, the water in the steam forming chamber 110 can be quickly boiled to quickly form and output steam.

Due to the communication effect of the water filling port 121, when the amount of water in the steam forming chamber 110 is reduced due to evaporation to form steam, the water in the water storage chamber 120 will be automatically replenished in the steam forming chamber 110 under the action of gravity, so that the water level of the water storage chamber 120 is reduced. The height of the water level in the steam forming chamber 110 is kept substantially equal. Since the replenishment of water is continuous and the amount is relatively small, the water in the steam forming chamber 110 can be kept boiling, thereby maintaining the output of steam. Since the water storage chamber 120 can continuously replenish the amount of water converted into steam to the steam forming chamber 110 and keep the steam forming chamber 110 boiling, the steam can be continuously generated.

In this embodiment, the water storage chamber 120 communicates with the outside atmosphere. It can be understood that if the steam heating chamber 210 and the steam forming chamber 110 are well sealed and the internal air pressure is higher than that of the water storage chamber 120, the water level of the steam forming chamber 110 can be lower than the water level of the water storage chamber 120, but the replenishment The port 121 is lower than the predetermined water level of the water storage chamber 120 and lower than the predetermined water level of the steam forming chamber 110, and the liquid water can keep the water seal of the water replenishment port 121, so that the object of the present invention can be achieved.

According to the above description, it can be understood that the steam forming chamber 110, the water storage chamber 120 and the steam heating chamber 210 are not limited to the realization of the above structure, and may also be realized by other specific structures. The top edge and the sealing plate connected to the top edge of the lower casing 101; the lower opening of the steam heating chamber 210 can cooperate with the parts of the lower body 100 of the pot to maintain a proper sealing degree of the lower part; the upper end of the steam forming chamber 110 can extend into the steam heating chamber 210 , and form appropriate steam outlets 112 on the peripheral surface, and so on.

In addition, the specific structure of the water supply port 121 can also be set according to actual needs, such as setting a curve or a Venturi shape.

It should be noted that during use, the water in the steam forming chamber 110 continues to boil, part of the water continues to be converted into steam, and the water in the steam forming chamber 110 continues to decrease, so that the water in the water storage chamber 120 continues to flow through the water supply port 121. Water is replenished to the steam forming chamber 110. Therefore, under normal conditions, water flows upward from the water storage chamber 120 to the steam forming chamber 110 through the water supply port 121 and gradually decreases; this is conducive to increasing the speed of steam rising and steaming efficiency. It can be understood that, in order to facilitate steam control and adapt to different steaming needs, the instant steamer can also include a steam transition chamber through which the steam output port 112 leads into the steam heating chamber and through the steam transition chamber Directs the steam flow so that the steam reaches the intended location.

The steam heating chamber 210 and the water storage chamber 120 can both be provided with air pressure balance holes, such as vent holes can be set on the cover 202 as air pressure balance holes to discharge steam so that the steam heating chamber 210 can maintain an appropriate pressure; Make the water storage chamber 120 communicate with the atmosphere through an air pressure balance hole. This can ensure proper pressure in the steam heating chamber 210 and the water storage chamber 120, maintain pressure balance, and ensure that the water in the water storage chamber 120 is automatically replenished into the steam heating chamber 210 smoothly, without the need to set a power mechanism such as a water pump .

It can be understood that the air pressure balance can also be realized through the matching gap. For example, the air pressure balance of the steam heating chamber 210 can be realized through the matching gap between the upper casing 201 and the cover 202, and the air pressure balance of the water storage chamber 120 can be realized through the upper end of the lower casing 101 and the upper casing. The bottom plate of the body 201 is realized by matching the clearance.

In the embodiment shown in FIGS. 1 and 2 , the instant steamer further includes a heating assembly 300 corresponding to the heating plate 111 . The heating assembly 300 can be fixed on the bottom of the pot lower body 100 . In this embodiment, the heating assembly 300 may be an electric heating assembly, and may include a heating fixing ring 310 , a heating plate 320 and a silicone ring 330 . The heating fixing ring 310 fixes the heating plate 320 and the silicone ring 330 on the bottom of the pot lower body 100 , and makes the heating plate 320 opposite to the heating plate 111 . In this embodiment, the heating fixing ring 310 is arranged around the periphery of the heating plate 111 . In this way, it can be ensured that the heating device only heats the steam forming chamber 110, thereby improving the heating efficiency, improving the steam production efficiency of the steam forming chamber 110, and ensuring the continuity of steam supply. The self-contained heating component 300 can facilitate the use of the quick steam pot.

In order to protect the heating plate 320 and the silicone ring 330 from scalding accidents, the heating assembly 300 also includes a bottom cover 340 located outside. Since the bottom cover 340 is fixed below the pot lower body 100, the bottom cover 340 also plays a supporting function.

Of course, it can be understood that the heating component 300 is not limited to an electric heating component, and may also be liquefied gas, calcium carbide or other heating components. Of course, an external heating device can also be used to heat the water in the steam forming chamber 110 .

Certainly, the heating assembly 300 may also include an anti-dry heating device. When the steam forming chamber 110 has no water and the heating assembly 300 performs dry heating, the anti-dry heating device controls the heating assembly 300 to stop heating according to the detected temperature or other parameters.

In a further embodiment, the outer wall of the water storage chamber 120 is a transparent outer wall, or is provided with a transparent observation window, and the water storage chamber 120 is provided with a water injection port. In this way, the amount of water in the water storage chamber 120 can be determined through the transparent outer wall or the transparent observation window, and water can be added to the water storage chamber 120 through the water injection port in time, thereby maintaining the working continuity of the instant steamer. Certainly, a water volume detection mechanism for detecting the water volume in the water storage chamber 120 may also be used, and the water volume in the water storage chamber 120 may also be determined according to the water volume detection mechanism.

The embodiments provided by the present invention have been described in detail above. In this paper, specific examples are used to illustrate the principles and implementation modes of the present invention, and the descriptions of the above embodiments are only used to help understand the core idea of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, some improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
