Detailed Description

The embodiments provided by the invention are described below with reference to the accompanying drawings. In this document, the use of the terms "upper" and "lower" are defined with reference to the use status of the rapid steamer.

Referring to fig. 1 and 2, fig. 1 is a sectional view of a rapid steamer according to an embodiment of the present invention, and illustrates the operation principle of the rapid steamer. Fig. 2 is an exploded view of the rapid steamer provided in the example, illustrating the components of the rapid steamer. The rapid steamer provided by the embodiment of the invention comprises a lower body 100 and an upper body 200.

The pot upper body 200 includes an upper case 201, a cover 202, and a steam rack 203. The lid 202 cooperates with the upper opening of the upper housing 201 to define a steam heating chamber 210 therein for receiving or containing the food ingredients to be steamed. The lower floor of the upper case 201 is closed at its periphery, and a middle portion thereof is formed with a through part corresponding to a steam outlet 112 of the steam forming chamber 110, which will be described later, to allow steam to enter the steam heating chamber 210. For steaming, in this embodiment, the inner wall of the upper case 201 also forms a support step. The pot upper body 200 further includes a steaming rack 203 engaged with the supporting step to place the food materials to be steamed.

In this embodiment, the lower body 100 includes a lower casing 101 and a separation ring 102. The lower case 101 includes an annular plate in the middle of which the partition ring 102 is located, and the annular plate and the lower end of the partition ring 102 are closed by an annular bottom plate, and the upper portion of the annular bottom plate forms a water storage chamber 120 for storing the standby water. The upper opening of the water storage chamber 120 is opposite to the peripheral closed portion of the bottom plate of the upper case 201, and covers the upper opening of the water storage chamber 120. The lower portion of the separating ring 102 is closed by a heated plate 111, and the upper portion of the heated plate 111 forms a vapor forming chamber 110 that generates vapor. The steam forming chamber 110 is opened at an upper portion thereof to be opposite to a through portion of a middle part of a bottom plate of the upper case 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 forming chamber 110. A water replenishing port 121 communicated with the inside and the outside is also arranged near the bottom edge part of the separating ring 102. The water replenishment port 121 is located between and communicates the water storage chamber 120 and the steam forming chamber 110.

In use, a proper amount of water is added to the water storage cavity 120 and the steam forming cavity 110, and the water level of the water storage cavity 120 and the water level of the steam forming cavity 110 are maintained to be equal due to the communication function of the water replenishing port 121. The water replenishing port 121 is close to the bottom, is lower than the steam outlet 112, is lower than the preset water storage level of the water storage cavity 120, and has a height difference of H. The water level of the water storage chamber 120 and the water level of the steam forming chamber 110 can maintain a water-tight seal of the water replenishing port 121.

The heated plate 111 at the lower portion of the vapor forming chamber 110 may then be heated by a heat source or heating device (e.g., an external liquefied gas cooker) to boil water in the vapor forming chamber 110 to form vapor. The formed steam reaches the steam via the steam outlet 112 of the steam forming chamber 110. However, in case of abnormal pressure (such as opening or closing the cover 202 in the middle), in order to prevent the water in the steam forming chamber 110 from flowing backward and to ensure the temperature of the steam forming chamber 110, and further to keep the water in the steam forming chamber 110 boiling, the water replenishing opening 121 may be provided with a check valve plate communicated from the water storage chamber 120 to the steam forming chamber 110, so as to ensure smooth replenishment of the water and to reduce outward flow of the steam forming chamber 110.

In the illustrated embodiment, the water storage chamber 120 and the steam forming chamber 110 are separated by an annular divider ring 102, and the water storage chamber 120 is in an annular configuration around the periphery of the steam forming chamber 110. Thus, the water storage cavity 120 can absorb the radiant heat of the steam forming cavity 110, thereby playing a role of preheating the water or supplemented water in the water storage cavity 120 on one hand, and further being beneficial to ensuring the continuous boiling of the steam forming cavity 110; on the other hand, the heat waste can be reduced, and the energy-saving effect is improved.

In another embodiment, to better "separate" the water storage chamber 120 from the steam forming chamber 110, avoid the steam forming chamber 110 from transferring excessive heat to the water storage chamber 120, ensure the temperature of the steam forming chamber 110, and maintain the steam forming chamber 110 continuously boiling, the separating ring 102 may be configured in a double-layer vacuum structure, i.e., the separating ring 102 includes an inner layer and an outer layer, and the inner layer and the outer layer are vacuumed, thereby reducing the heat transfer from the steam forming chamber 110 to the water storage chamber 120 through "conduction". Further, to reduce the heat transfer to the water storage cavity 120 by "radiation", the inner surface of the outer layer of the spacer ring 102 may be configured as a reflective surface, and the outer surface of the inner layer may be configured as a rough or black surface to absorb the reflected radiation heat.

Of course, in the case where the partition ring 102 has a double-layer vacuum structure, the water replenishment port 121 may be formed by a pipe passing through the double-layer vacuum structure. In order to preheat the water introduced into the steam forming chamber 110 through the water replenishment port 121, a preheating passage extending a predetermined distance in a circumferential direction may be provided in an inner layer of the partition ring 102, so that the replenished water passes through the preheating passage and then enters the steam forming chamber 110, thereby increasing the temperature of the water in the replenished steam forming chamber 110 and ensuring continuous boiling of the steam forming chamber 110.

It is understood that one fast steamer may include a plurality of water storage chambers 120 with the plurality of water storage chambers 120 located at the periphery of the steam forming chamber 110.

As shown in fig. 1 and 2, at least a portion of the transverse cross-sectional area of the steam forming chamber 110 delivers the formed steam from the lower heating chamber 210 to the steam heating chamber 210 to heat and steam the food ingredients. Since only the water of the steam forming chamber 110 needs to be heated, the water in the steam forming chamber 110 can be boiled quickly, and steam is formed and output quickly.

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

In this embodiment, the water storage chamber 120 is connected to the external atmosphere. It can be understood that if the steam heating chamber 210 and the steam forming chamber 110 have good sealing performance and the internal air pressure is higher than the air pressure 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 water replenishing port 121 is lower than the predetermined water level of the water storage chamber 120, and at the same time, the liquid water can keep the water-tight sealing of the water replenishing port 121 below the predetermined water level of the steam forming chamber 110, so as to achieve the purpose of the present invention.

From the foregoing, it will be appreciated that the steam formation chamber 110, the water storage chamber 120, and the steam heating chamber 210 are not limited to being implemented by the above-described structure, and may be implemented by other specific structures, such as a sealing plate that is connected to the top edge of the spacer ring 102 and the top edge of the lower housing 101 may be provided at the upper opening of the water storage chamber 120; the lower opening of the steam heating cavity 210 can be matched with the part of the cooker lower body 100 to keep the proper sealing degree of the lower part; the upper end of the steam forming chamber 110 may extend into the steam heating chamber 210 and form a suitable steam outlet 112 on the periphery, and so on.

In addition, the specific structure of the water replenishing 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 the use process, the water in the steam forming chamber 110 is continuously boiling, part of the water is continuously converted into steam, and the water in the steam forming chamber 110 is continuously reduced, so that the water in the water storage chamber 120 is continuously replenished to the steam forming chamber 110 through the water replenishing port 121, therefore, the water flowing from the water storage chamber 120 to the steam forming chamber 110 through the water replenishing port 121 is gradually reduced upwards in the normal state; therefore, the steam rising speed is improved, and the steam steaming efficiency is improved. It will be appreciated that in order to facilitate steam control to suit different steaming requirements, the rapid steamer may further comprise a steam transition chamber through which the steam outlet 112 leads into the steam heating chamber, and through which a steam flow is directed to bring the steam to a predetermined position.

The steam heating cavity 210 and the water storage cavity 120 may be both provided with air pressure balancing holes, for example, air holes may be provided on the lid 202 as air pressure balancing holes to exhaust steam, so that the steam heating cavity 210 maintains a proper pressure; the water storage chamber 120 may be kept in communication with the atmosphere through an air pressure balancing hole. Therefore, the proper pressure in the steam heating cavity 210 and the water storage cavity 120 can be ensured, the pressure balance is kept, and the water in the water storage cavity 120 is ensured to be smoothly and automatically supplemented into the steam heating cavity 210 without arranging a power mechanism such as a water pump and the like.

It is understood that the air pressure balance can also be achieved through the fit clearance, for example, the air pressure balance of the steam heating chamber 210 can be achieved through the fit clearance between the upper casing 201 and the cover 202, and the air pressure balance of the water storage chamber 120 can be achieved through the fit clearance between the upper end of the lower casing 101 and the bottom plate of the upper casing 201.

In the embodiment shown in fig. 1 and 2, the rapid steamer further comprises a heating assembly 300 corresponding to the heated plate 111. The heating assembly 300 may be fixed to 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 at the bottom of the pot lower body 100, and makes the heating plate 320 opposite to the heated plate 111. The heating fixing ring 310 in this embodiment is disposed around the periphery of the heated plate 111. This ensures that the heating device heats only the vapor forming chamber 110, improves the heating efficiency, improves the efficiency of the vapor forming chamber 110 in producing vapor, and ensures the continuity of the vapor supply. The self-contained heating assembly 300 can facilitate the use of the rapid steamer.

In order to protect the heating plate 320 and the silicone ring 330 from burning accidents, the heating assembly 300 further includes a bottom cover 340 located at the outside. Since the bottom cover 340 is fixed under the pot lower body 100, the bottom cover 340 also functions as a support.

Of course, it is understood that the heating assembly 300 is not limited to an electrical heating assembly, but may be a liquefied gas, carbide, or other heating assembly. Of course, external heating means may also be used to heat the water of the steam forming chamber 110.

Of course, the heating assembly 300 may further include a dry-heating preventing device for controlling the heating assembly 300 to stop heating according to the detected temperature or other parameters when the heating assembly 300 is dry-heated without water in the steam forming chamber 110.

In a further embodiment, the outer wall of the water storage cavity 120 is a transparent outer wall, or is provided with a transparent observation window, and the water storage cavity 120 is provided with a water injection port. Therefore, the water amount in the water storage cavity 120 can be determined through the transparent outer wall or the transparent observation window, and water is added to the water storage cavity 120 through the water filling port in time, so that the working continuity of the rapid steam cooker is kept. Of course, the water level detection means may detect the water level in the water storage chamber 120, and the water level in the water storage chamber 120 may be determined by the water level detection means.

The embodiments provided by the present invention have been described in detail above. The principles and embodiments of the present invention have been described herein using specific examples, which are presented only to assist in understanding the core concepts of the present invention.
