Steam circulating cooking electric cooker

Abstract

This utility model discloses a steam-circulating electric cooker, relating to the field of electric cooker technology. The utility model includes a heating base, a steam circulation assembly, and a sealing assembly. A sealing cover is fixedly connected to the top of the heating base. A pot body is housed within the inner cavity of the sealing cover, and a pot lid is mounted on the top of the pot body. The steam circulation assembly includes a connecting pipe, the bottom end of which communicates with the sealing cover. This utility model, through the steam circulation assembly and the communication structure between the connecting pipe and the sealing cover, guides high-temperature steam generated inside the pot body through an injection pipe into a corrugated pipe, and then transports it through the connecting pipe to the inside of the sealing cover, forming a closed steam circulation loop. This prolongs the residence time of the steam within the sealing cover. Combined with the guiding effect of the guide ring, this ensures that the heat carried by the steam continuously acts on the surface of the pot body, compensating for heat loss caused by steam dissipation from the pot body, thereby reducing the frequency of repeated heating of the heating base.

Description

Technical Field

[0001] This utility model belongs to the field of electric cooker technology, and in particular relates to a steam-circulating electric cooker. Background Technology

[0002] An electric cooker is a small kitchen appliance that uses electric energy to heat food. It converts electrical energy into heat energy through an electric heating element, enabling it to perform various cooking functions such as boiling, stewing, steaming, and heating. It is compact in size and easy to operate, making it suitable for cooking noodles, porridge, stewing soup, steaming vegetables, or heating milk, thus meeting the simple dietary needs of a fast-paced life.

[0003] Existing electric cookers generate a large amount of high-temperature steam during the stewing process. This steam escapes directly to the outside through the vent or gaps in the pot, resulting in significant heat loss. Because the heat energy carried by the steam is not effectively utilized, the temperature inside the pot is difficult to maintain and requires continuous additional energy to replenish the heat. This not only increases energy consumption but also prolongs the cooking time of food, making it unsuitable for use.

[0004] To address these issues, we offer a steam-circulating electric cooker. Utility Model Content

[0005] The purpose of this invention is to provide a steam-circulating electric cooker. By combining the steam circulation component and the sealing component, it solves the problem that existing electric cookers do not have a steam circulation function, and the steam generated during stewing is directly released, which easily leads to heat loss, making it difficult to maintain a stable temperature inside the pot, increasing energy consumption and food cooking time.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a steam-circulating electric cooker, comprising a heating base, a steam circulation assembly, and a sealing assembly. A sealing cover is fixedly connected to the top of the heating base. A pot body is housed within the inner cavity of the sealing cover, and a pot lid is mounted on the top of the pot body. The steam circulation assembly includes a connecting pipe, the bottom end of which communicates with the sealing cover, and the top of which is connected to a corrugated pipe. An injection pipe is connected to the end of the corrugated pipe furthest from the connecting pipe, and the bottom end of the injection pipe extends into the interior of the pot lid. A guide ring is fixedly connected to the inner wall of the sealing cover. The sealing assembly includes two connecting brackets, the bottom of which is movably connected to the sealing cover, and a positioning bracket movably connected to the top of each connecting bracket. A screw is mounted on the top of the positioning bracket, and the bottom of the screw passes through the positioning bracket and is movably connected to a pressure plate.

[0008] The present invention is further configured such that a handle is fixedly connected to the top of the pot lid, and a quick connector is connected to the left side of the top of the pot lid. The handle makes it easy for the user to open the pot lid, and the quick connector makes it easy to connect the injection tube to the pot lid.

[0009] The present invention is further configured such that a mounting bracket is fixedly connected to the surface of the connecting pipe, and the right side of the mounting bracket is fixedly connected to the sealing cover. The mounting bracket can install and fix the connecting pipe to prevent it from becoming loose.

[0010] The present invention is further configured such that an exhaust pipe is connected to the right side of the sealing cover, a drain pipe is connected to the bottom of the right side of the sealing cover, and a plug is interference-fitted to the inner wall of the drain pipe. The exhaust pipe can discharge the circulating steam, the drain pipe can discharge the condensate, and the plug can seal the drain pipe.

[0011] The present invention is further configured such that a knob is fixedly connected to the top of the screw, and a threaded hole for cooperating with the screw is opened on the top of the positioning frame. The knob facilitates the user to rotate the screw, and the threaded hole can cooperate with the screw to control the working height of the pressure plate.

[0012] The present invention is further provided that the bottom of the heating base is fixedly connected with an isolation support block, the number of which is four and they are evenly distributed on the bottom of the heating base. The isolation support block can support the heating base, prevent it from directly contacting the table, and improve the heat dissipation effect of the heating base.

[0013] The present invention is further configured such that a high-temperature resistant sealing ring is fixedly connected to the bottom of the pot lid, and the surface of the pot body is in contact with the guide ring. The high-temperature resistant sealing ring can increase the sealing effect between the pot lid and the pot body, and the pot body in contact with the guide ring can increase the sealing effect, so that steam can flow along the surface of the pot body.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model utilizes a steam circulation component and a connecting structure between the connecting pipe and the sealing cover to guide the high-temperature steam generated inside the pot body through the injection pipe into the corrugated pipe, and then through the connecting pipe into the sealing cover, forming a closed steam circulation loop. This extends the residence time of the steam in the sealing cover. Combined with the guiding ring's function of guiding the steam flow, it ensures that the heat carried by the steam continuously acts on the surface of the pot body, compensating for the heat loss caused by the steam dissipation from the pot body. This reduces the frequency of repeated heating of the heating base, lowers energy consumption, and at the same time, the circulating steam ensures that the food is heated evenly, shortening the overall cooking time.

[0016] 2. This utility model uses a sealing component, in which the connecting frame and the positioning frame work together, and the screw drives the pressure plate to apply a vertical downward pressing force to the pot lid. Combined with the high-temperature resistant sealing ring set at the bottom of the pot lid, it achieves all-round pressing and sealing of the pot body opening edge, preventing steam from escaping from the gaps in the pot lid. This allows the steam generated by cooking food inside the pot to be transported into the sealing cover, keeping the pot body temperature stable and avoiding energy waste caused by frequent heat replenishment.

The bottom of the connecting brackets 61 is movably connected to the sealing cover 2, and the top of the connecting brackets 61 is movably connected to a positioning bracket 62. A screw 63 is provided on the top of the positioning bracket 62, and the bottom of the screw 63 passes through the positioning bracket 62 and is movably connected to a pressure plate 64.

[0027] Specifically: the sealing cover 2 can wrap the pot body 3 to prevent the heat from the heating base 1 from dissipating. The heating base 1 can generate heat to heat the pot body 3. The pot body 3 and the lid 4 can seal the food being cooked to prevent the heat from dissipating quickly. The injection pipe 53 can be inserted into the lid 4. The corrugated pipe 52 facilitates the adjustment of the position of the injection pipe 53. The connecting pipe 51 can transport the steam generated by cooking food inside the pot body 3 to the sealing cover 2. The circulating steam maintains the temperature inside the pot body 3 and prevents the temperature inside the pot body 3 from dropping due to steam loss during cooking. The guide ring 54 is used to increase the residence time of steam inside the sealing cover 2. The connecting bracket 61 facilitates the installation of the positioning bracket 62. The screw 63 allows the user to easily control the height of the pressure plate 64. The pressure plate 64 is used to press the lid 4 so that the lid 4 can fit tightly against the pot body 3.

[0028] Example 2

[0029] Please see Figure 1-5 Based on Embodiment 1, a handle is fixedly connected to the top of the pot lid 4, a quick connector is connected to the left side of the top of the pot lid 4, a mounting bracket is fixedly connected to the surface of the connecting pipe 51, the right side of the mounting bracket is fixedly connected to the sealing cover 2, an exhaust pipe 7 is connected to the right side of the sealing cover 2, a drain pipe 8 is connected to the bottom of the right side of the sealing cover 2, a plug is interference-fitted to the inner wall of the drain pipe 8, a knob is fixedly connected to the top of the screw 63, a threaded hole for use with the screw 63 is opened on the top of the positioning bracket 62, an isolation support block is fixedly connected to the bottom of the heating base 1, there are four isolation support blocks, and they are evenly distributed on the bottom of the heating base 1, a high-temperature resistant sealing ring 9 is fixedly connected to the bottom of the pot lid 4, and the surface of the pot body 3 is in contact with the guide ring 54.

[0030] Specifically: the handle facilitates the user to open the pot lid 4; the quick connector facilitates the connection of the injection pipe 53 to the pot lid 4; the mounting bracket can install and fix the connecting pipe 51 to prevent it from loosening; the exhaust pipe 7 can discharge the circulating steam; the drain pipe 8 can discharge the condensate; the plug can seal the drain pipe 8; the knob facilitates the user to turn the screw 63; the threaded hole can cooperate with the screw 63 to control the working height of the pressure plate 64; the isolation support block can support the heating base 1 to prevent it from directly contacting the table and at the same time improve the heat dissipation effect of the heating base 1; the high-temperature resistant sealing ring 9 can increase the sealing effect between the pot lid 4 and the pot body 3; the pot body 3, which is in contact with the guide ring 54, can increase the sealing effect, allowing steam to flow along the surface of the pot body 3.

[0031] The working principle of this invention is as follows: First, the pot body 3 is placed inside the sealing cover 2. The heating base 1 heats the pot body 3, causing the food inside the pot body 3 to generate steam. The steam enters the injection pipe 53 through the pot lid 4, and then passes through the corrugated pipe 52 and the connecting pipe 51 before re-entering the sealing cover 2. At this time, the guide ring 54 inside the sealing cover 2 guides the steam, causing it to flow along the surface of the pot body 3. The heat carried by the steam is used to compensate for the heating of the pot body 3, reducing the cooking time of the food and thus reducing the energy consumption of the heating base 1. Simultaneously, the two positioning brackets 62 are closed, and the position of the pressure plate 64 is adjusted by rotating the screw 63, so that the pressure plate 64 applies pressure to the pot lid 4. In conjunction with the high-temperature resistant sealing ring 9, the sealing between the pot lid 4 and the pot body 3 is improved, preventing steam from escaping from the gaps in the pot lid 4. When condensation occurs during the steam circulation process, the condensation is discharged through the drain pipe 8, while excess steam is discharged through the exhaust pipe 7, ensuring the pressure balance inside the sealing cover 2. By recycling the steam, energy loss is reduced, and the circulating steam ensures that the food is heated evenly, shortening the overall cooking time.
