Description

Technical Field

[0001] This utility model relates to a rice steamer, and in particular to a novel rice steamer. Background Technology

[0002] Currently, most ordinary rice steamers on the market have a structure that involves installing one or more steaming baskets on the pot body, with a lid placed on top of the baskets. When the pot is heated to steam rice, the steaming baskets and lids themselves easily dissipate heat. Secondly, this structure makes it impossible to regulate the steam pressure inside the pot, which limits the pot's practical function. In addition, when steaming food, the water vapor inside the pot can easily escape through the lid, and this escaped water vapor carries away a lot of heat, wasting energy. Summary of the Invention

[0003] To overcome the shortcomings of the aforementioned pots, this utility model provides a novel rice steamer. This novel rice steamer consists of an electromagnet mounted on the pot body of an electric heating pot, a novel steaming basket, and a pressure-limiting heat-insulating cover that prevents the loss of water vapor and heat. The steam pressure maintained within the inner cavity of the pressure-limiting heat-insulating cover can be changed by the electromagnet. This is achieved by connecting a potentiometer in series with the electromagnet and adjusting a novel knob on the potentiometer to change the current, thereby changing the electromagnet's attraction force and thus altering the steam pressure maintained within the pressure-limiting heat-insulating cover. When heating water in the novel pot to steam rice, the generated steam is confined by the pressure-limiting heat-insulating cover, making it difficult for it to escape outside the pot. Furthermore, the pressure-limiting heat-insulating cover provides heat preservation and pressure maintenance, which helps to speed up the cooking process and save energy, thus constituting a novel rice steamer.

[0004] To achieve the above tasks, a new type of pot body is first manufactured. The structure of the new pot body is as follows: a step is added to the edge of a regular pot body. The width of the step is large enough to simultaneously place a new type of steamer and a pressure-limiting heat-insulating cover. Three holes for installing electromagnets are machined on the back of the step. The shape of the holes is such that if the pot body is made of a material that can be attracted by a magnet, such as iron, it is made into a through hole; if the pot body is made of a material that cannot be attracted by a magnet, such as aluminum or nickel-containing stainless steel, it is made into a blind hole. Whether it is a blind hole or a through hole, an electromagnet can be installed in the hole. An upward-protruding edge is added around the step. Multiple exhaust grooves are machined on the inner side of the edge. The upper half of the edge is then bent inward into a 90° flange. The flange is then evenly divided into 12 parts. Based on the 12 equal parts, the flange is cut off at intervals to make 6 openings. The remaining flange and the step form 6 locking joints.

[0005] The pressure-limiting heat-insulating cover described above has a structure consisting of two shells, an inner and an outer shell, with insulation material or a vacuum between them to prevent heat loss from the inner cavity. The bottom of the cover has six outward-facing flanges that fit into six openings in the new type of pot and rest on a step. Rotation allows the flanges to engage with six locking slots. A ring of iron plates is installed inside the bottom of the cover. These plates are attracted by an electromagnet mounted on the pot. Thus, with a fixed weight, the strength of the electromagnet's attraction to the iron plates can be adjusted by changing the current flowing to the electromagnet, thereby increasing or decreasing the bonding force between the cover and the pot at the step. The weight of the pressure-limiting heat-insulating cover plus the electromagnet's attraction is designed according to the pressure required by the food being steamed. When the food requires lower pressure, the weight plus the electromagnet's attraction is smaller; conversely, when the food requires higher pressure, the weight plus the electromagnet's attraction is larger. This design can meet the needs of steaming different foods. When steam pressure in the inner cavity of the cover exceeds the corresponding setting, the pressurized steam will overcome the weight of the pressure-limiting heat insulation cover plus the attraction of the magnet, lifting the pressure-limiting heat insulation cover upward and separating it from the contact with the stepped surface of the pot. The steam will be discharged from the gap between the bottom surface of the pressure-limiting heat insulation cover and the stepped surface of the pot and the exhaust groove, which plays a safety protection role.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: First, a new type of pot body is made. The structure of the new pot body is as follows: a step is added to the edge of the pot body, and an upward-protruding edge is added around the step. The edge and the pot body are integral. Then, multiple exhaust grooves are evenly distributed on the inner side of the edge. The upper half of the edge is bent inward to form a 90° flange. The flange is then evenly divided into 12 equal parts. Based on the 12 equal parts, the flange is cut at intervals, and 6 openings are made on the flange. The remaining flange and the step surface form 6 locking slots. Then, three holes for installing electromagnets are processed on the back of the step. The shape of the holes is as follows: if the pot body is made of a material that cannot be attracted by a magnet, such as aluminum or nickel-containing stainless steel, three blind holes are made; if the pot body is made of a material that can be attracted by a magnet, such as iron, three through holes are made. Electromagnets can be installed in the holes, whether they are blind holes or through holes. The function of adding a step to the new pot body is to install a new type of steamer on the inner edge of the step. A pressure-limiting heat-insulating cover can be installed on the step between the new steamer and the edge of the new pot body. The pressure-limiting and heat-insulating cover is composed of two layers of stainless steel or aluminum plates, with insulation material or a vacuum between the two layers to prevent heat loss from the inner cavity. The bottom surface of the cover has six evenly distributed flanges that fit into openings on the new type of pot body and can then be rotated into six locking slots on the pot body. A ring of iron plates is fixed inside the bottom surface of the cover. This secure installation does not affect the magnetic force of the electromagnet, which is attracted by the nickel-containing stainless steel or aluminum shell. Thus, with a fixed weight, the suction force can be adjusted by changing the current to the electromagnet, thereby increasing or decreasing the bonding force between the cover and the pot body at the step, controlling the steam pressure inside the cover to accommodate different foods. The electromagnet suction force is changed by connecting a potentiometer in series with the electromagnet. Adjusting a new knob on the potentiometer changes the current to the electromagnet, thus changing the suction force and consequently the steam pressure maintained inside the pressure-limiting and heat-insulating cover. The new knob on the potentiometer has markings corresponding to the strength of the magnet's attraction. These markings help set the required steam pressure inside the pressure-limiting insulation cover. The steam pressure inside the cover is set according to the pressure required by the food being steamed. With a fixed weight for the cover, a smaller electromagnet force is needed when the food requires lower steam pressure, and vice versa. Users can adjust the potentiometer knob to adjust the attraction force as needed. For example, if a user sometimes needs to steam vegetarian food and sometimes meat, a smaller current can be used for the former, and a larger current for the latter. Of course, if the user doesn't need the electromagnet's attraction and feels that the steam pressure maintained by the cover's own weight is sufficient, the current can be set to zero, rendering the electromagnet inactive.With this design, when the steam pressure inside the hood exceeds the corresponding setting during rice steaming, the pressurized steam will overcome the weight of the pressure-limiting insulation hood plus the attraction of the electromagnet, lifting the hood upwards and separating it from the step of the new pot body. The steam will then escape from the gap between the bottom of the pressure-limiting insulation hood and the step surface of the new pot body, as well as from the venting grooves on the edge of the new pot body, thus providing a safety function. However, for safety reasons, the design of this new rice steamer specifies a safety allowable range: the combined effect of the weight of the insulation hood and the maximum attraction of the magnet cannot exceed the maximum value permitted within the specified safety range. To prevent the distance between the pressure-limiting insulation hood and the step of the new pot body from becoming too large when venting, the thickness of the flange on the pressure-limiting insulation hood is made smaller than the gap formed between the flange on the new pot body and the step, ensuring that the distance the pressure-limiting insulation hood travels away from the step when rising will not exceed this gap.

[0007] To improve the sealing between the bottom surface of the pressure-limiting insulation cover and the step of the new pot body, a silicone sealing gasket is installed on the step of the new pot body.

[0008] To ensure the electromagnet and its connecting wires installed on the new pot body are stable and reliable, a protective ring made of heat-resistant and insulating plastic is installed and fixed below the step of the new pot body. Three stabilizing holes for installing the electromagnet are evenly distributed on the protective ring, and a groove is machined on the lower end face. A conduit can be installed in the groove, and the wires connecting the electrical mechanism and the electromagnet are installed in the conduit.

[0009] In order to understand the temperature and pressure inside the pressure-limiting insulation cover, a temperature gauge and a pressure gauge are installed on the cover. The temperature gauge can be a digital temperature gauge and a digital pressure gauge, or a regular temperature gauge and a pressure gauge can be installed.

[0010] To power the digital temperature and pressure gauges installed on the pressure-limiting insulation cover, a new type of electrical plug is installed below the upper edge of the cover. The plug shell is made of heat-resistant and insulating plastic, which protects the internal sockets and ensures user safety. The internal socket is a flexible socket made of a flexible metal sheet. The wires connected to the flexible socket are connected to the digital temperature and pressure gauges. The socket is rectangular, and the pins can move up and down after insertion. Additionally, an electrical socket is installed on the outer edge of the new pot body. The socket shell is made of heat-resistant and insulating plastic, which protects the internal pins and ensures user safety.

[0011] To ensure the digital thermometer and pressure gauge are powered on precisely during use, the electrical plug and socket are positioned relative to the pressure-limiting insulation cover and the new pot body as follows: when the bottom flange of the pressure-limiting insulation cover is installed at the opening on the new pot body, and then the pressure-limiting insulation cover is rotated so that its flange enters the latch on the new pot body, the plug is precisely inserted into the socket. If the pressure-limiting insulation cover moves upward, it will cause the plug's internal socket to move upward as well. Since the socket is rectangular, it can move upward or downward without the socket and its internal pins remaining stationary.

[0012] If ordinary thermometers and pressure gauges are installed on the pressure-limiting insulation cover, since these gauges do not require electricity, no plugs or sockets are installed on the pressure-limiting insulation cover or the new pot body. The temperature and pressure inside the cover can be understood by looking at the pointers on the gauges.

[0013] When using the new type of rice cooker, add an appropriate amount of water, then install the new type of steamer basket on the inside of the steps of the new pot body. Place the food to be steamed inside the new type of steamer basket. Install a pressure-limiting heat-insulating cover on the steps between the outside of the new type of steamer basket and the edge of the new pot body. During installation, first align the flange of the pressure-limiting heat-insulating cover with the opening of the flange on the new pot body, then install the cover on the steps of the new pot body, and then rotate the cover so that the flange enters the locking slot of the flange on the pot body. At this time, the electrical plug on the cover is inserted into the socket on the pot body, and the power of the digital display is turned on. This allows you to check the internal condition of the pressure-limiting heat-insulating cover through the digital display temperature gauge or pressure gauge during subsequent rice steaming. Then, adjust the new type of knob on the potentiometer to the position required for the food, and then you can turn on the power to heat the new type of rice cooker. The steam generated inside the pot is restricted by the pressure-limiting heat-insulating cover, making it difficult to escape outside the pot, and a certain steam pressure is formed in the inner cavity of the pressure-limiting heat-insulating cover, which is conducive to rapid heating of food. Secondly, since the pressure-limiting heat-insulating cover can keep the heat insulated, it is not easy for the heat to dissipate, which helps to save energy.

[0014] The beneficial effects of this utility model are as follows: A new type of steamer and a pressure-limiting heat insulation cover that can prevent the loss of water vapor and heat are installed on a new type of rice steamer. The steam pressure inside the pressure-limiting heat insulation cover can be changed by rotating a new type of knob on a potentiometer to adapt to steaming different foods. When heating water in the new pot to steam rice, the steam generated is restricted by the pressure-limiting heat insulation cover and is difficult to escape outside the pot. Secondly, the pressure-limiting heat insulation cover can play a role in heat preservation and pressure preservation, which is conducive to speeding up the steaming of food and saving energy.

Detailed implementation method:

[0050] Figure 1 This is a schematic diagram illustrating the specific structure of a new type of rice steamer 1. From... Figure 1 It can be seen that a new type of rice cooker 1 has an electric heating pot 9 below it. The electric heating pot 9 is equipped with pot handles 4, power sockets 10, new knobs 11, and electrical sockets 3. The electric heating pot 9 is equipped with a pressure limiting heat preservation cover 6 above it. The pressure limiting heat preservation cover 6 is equipped with a handle 5, a digital display temperature gauge 7, a digital display pressure gauge 8, and an electrical plug 2.

[0052] Figure 5 yes Figure 1 The partial exploded view shows that an electrical socket 3 is installed on the outer edge of the electric hot pot 9, and a new type of steamer 12 is installed on top. A pressure-limiting heat insulation cover 6 is installed on the outside of the new type of steamer 12. A digital display temperature gauge 7, a digital display pressure gauge 8, and an electrical plug 2 are installed on the pressure-limiting heat insulation cover 6.

[0054] Figure 7 yes Figure 6The diagram shows a partial exploded view of the electric hot pot 9. It can be seen that an electrical control mechanism 20 is installed inside the electrical cover 22. A wire protection tube 21 extends from inside the electrical cover 22 and connects to the inner cavity of a conduit 18. A wire is inside the wire protection tube 21; one end of the wire is connected to the electrical control mechanism 20, and the other end passes into the conduit 18 and connects to an electromagnet 19. The lower part of the electromagnet 19 is installed in a stabilizing hole 17 on a protective ring 16. The conduit 18 is installed and fixed in a groove inside the protective ring 16. The protective ring 16 is installed and fixed on the new pot body 14. The electric heater 15 is fixed to the bottom of the new pot body 14, and a silicone sealing gasket 13 is installed on the step of the new pot body 14.

Figure 12 yes Figure 11 An enlarged view of part BB. The image shows that the lower part of electromagnet 19 is installed in the stabilizing hole 17 of the protective ring 16, and the upper part of electromagnet 19 is installed in the electromagnet hole 29 on the new pot body 14. Conduit 18 is installed in the groove of the protective ring 16, and the wires inside conduit 18 are connected to electromagnet 19. An electrical control mechanism 20 and potentiometer 23 are installed inside the electrical cover 22. The internal wiring of the power socket 10 connects to the electrical control mechanism 20. After being controlled by the electrical control mechanism 20, one output connects to the electric heater 15, and the other output is a safe voltage, connecting to potentiometer 23. The output wire of potentiometer 23 enters the wire protection tube 21, then enters conduit 18 and connects to the wires inside. The wires inside conduit 18 are connected to electromagnet 19.

Figure 16 This is a bottom view of the new pot body 14. Figure 17 yes Figure 16 FF direction section view, Figure 18 yes Figure 14 A magnified view of the CC region. Figure 19 yes Figure 17 A magnified view of the KK area. Figure 20 yes Figure 15An enlarged view of the EE part is shown in the figure. As can be seen, the structure of the new pot body 14 involves adding a step 24 to the edge of the pot body. The width of the step 24 is sufficient to install the pressure-limiting heat-insulating cover 6 and the new steamer 12. An upward-protruding edge is added around the step 24, and the edge is integral with the new pot body 14. Multiple exhaust grooves 26 are evenly distributed on the inner side of the edge. The upper part of the edge is bent inwards into a 90° flange, which is then evenly divided into 12 parts. Based on these 12 parts, the flange is cut off at intervals to create 6 openings 28. The remaining flanges 27 form 6 locking slots 25 with the step 24. Three electromagnet holes 29 are also machined on the back of the step. The shape of the holes is such that if the pot body is made of a material that can be attracted by a magnet, such as iron, they are made as through holes; if the pot body is made of a material that cannot be attracted by a magnet, such as aluminum or nickel-containing stainless steel, they are made as blind holes. Regardless of whether the holes are blind or through holes, electromagnets 19 can be installed inside them. The reason for making blind holes or through holes is that when aluminum or nickel-containing stainless steel is made into blind holes, magnetic force can attract the iron sheet 34 inside the pressure-limiting insulation cover 6 through the blind holes. However, when iron is made into blind holes, the magnetic lines of force will form a closed circuit, making it difficult to attract the iron sheet 34 on the pressure-limiting insulation cover 6.

[0057] Figure 21 This is a structural schematic diagram of the pressure-limiting heat insulation cover 6. Figure 22 yes Figure 21 The main view, Figure 23 yes Figure 21 Left view, Figure 24 yes Figure 21 Top view, Figure 25 yes Figure 23 HH direction sectional view, Figure 26 yes Figure 25 An enlarged view of the JJ part. The image shows that the pressure-limiting heat-insulating cover 6 consists of an outer shell 31 and an inner shell 32, with the cavity between the outer shell 31 and the inner shell 32 filled with heat-insulating material 33. The bottom surface of the pressure-limiting heat-insulating cover 6 has six evenly distributed flanges 30. These flanges 30 can be inserted into the opening 28 on the new pot body 14, or rotated into the latch 25. A ring of iron plates 34 is fixed inside the bottom surface of the pressure-limiting heat-insulating cover 6, tightly attached to the bottom outer shell. The iron plates 34 are securely installed inside the bottom of the pressure-limiting heat-insulating cover 6 without affecting the magnetic force of the electromagnet 19, which attracts the cover through a stainless steel or aluminum plate. Thus, with a fixed weight, the suction force can be changed by altering the current flowing to the electromagnet 19, thereby increasing or decreasing the bonding force between the cover and the pot body at the step, in order to control the steam pressure inside the cover to accommodate different foods.

[0058] Figure 27 yes Figure 21 The exploded view of a portion of the pressure-limiting insulation cover 6 is shown. Figure 28 yes Figure 27Enlarged view of the TT part. As can be seen from the figure, the iron sheet 34 is composed of blocks. The electrical plug 2 is installed on the pressure-limiting heat insulation cover 6. The electrical plug 2 has a flexible socket 35 made of a flexible metal sheet installed inside. The flexible socket 35 is rectangular. When the pin is inserted, the flexible socket 35 can move up and down.

[0059] Figure 29 This is an exploded view of the electrical plug 2 and electrical socket 3 in the diagram. Figure 30 yes Figure 29 A magnified view of the LL region. Figure 31 yes Figure 29 An exploded view of the electrical plug 2 and electrical socket 3 from another direction. The diagram shows in detail that the electrical socket 3 has a pin installed inside, and the electrical plug 2 has a rectangular elastic socket 35 made of a flexible metal sheet. The height of the socket 3 is 3 mm greater than the height of the inserted part of the electrical plug 2. After the electrical plug 2 is inserted into the socket 3, it can move up and down within the socket 3. This up-and-down movement is designed so that when the electrical plug 2 moves upwards with the pressure-limiting insulation cover 6 fixed together to release steam, although the pin inside the socket 3 remains stationary, the electrical plug 2 can move up or down. Because the socket 35 is made of a flexible metal sheet, it can maintain contact with the pin without affecting the power supply.

[0060] Figure 32 This is a schematic diagram of the specific structure of the present invention for installing a common thermometer 36 and a pressure gauge 37. Since the common thermometer 36 and pressure gauge 37 can be directly connected to the inside of the pressure-limiting insulation cover 6 and the reading can be obtained directly by the pointer, no electricity is required. Therefore, the electrical plug 2 and the electrical socket 3 are not installed on this new type of rice cooker.

[0061] During implementation, first hold the handle 5 on the pressure-limiting heat insulation cover 6 and remove it from the new type of rice cooker 1. Then remove the new type of steamer 12. Next, add an appropriate amount of water to the new type of pot body 14. Then, install the new type of steamer 12 on the inner edge of the step 24 on the new type of pot body 14. Then, put the food to be steamed into the steamer 12. Then, install the flange 30 of the pressure-limiting heat insulation cover 6 into the opening 28 on the new type of pot body 14, so that the bottom surface of the pressure-limiting heat insulation cover 6 rests on the silicone sealing gasket 13 installed on the step 24 on the new type of pot body 14. Then, rotate the pressure-limiting heat insulation cover 6 so that the flange 30 enters the slot 25 on the pot body. At this time, the electrical plug 2 is inserted. The power supply to the digital thermometer 7 and digital pressure gauge 8 is connected in the electrical socket 3 on the pot body. Then, the new knob 11 on the potentiometer 23 is adjusted to the position required for the food. Then, the new type of rice steamer 1 can be powered on. At this time, the iron plate 34 installed inside the bottom surface of the pressure limiting heat insulation cover 6 will be attracted by the electromagnet 19 fixed on the new pot body 14, so that the steam generated in the pot is limited by the pressure limiting heat insulation cover 6 and is difficult to escape outside the pot. A certain temperature and steam pressure are formed in the inner cavity of the pressure limiting heat insulation cover 6, and its value can be read by the thermometer or pressure gauge. Secondly, since the pressure limiting heat insulation cover 6 can play a heat preservation role, the heat is not easily lost, which is conducive to quickly heating and steaming food and saving energy. During steaming, when the steam pressure inside the pressure-limiting heat insulation cover 6 is higher than the set pressure, the steam will generate an upward thrust that overcomes the weight of the cover 6 and the attraction of the electromagnetic magnet 19, causing it to leave the silicone sealing gasket 13 on the step 24 of the new pot body 14. The steam will then escape through the gaps between them and the exhaust groove 26. Because the vertical distance within the latch 25 is greater than the thickness of the flange 29 of the pressure-limiting heat insulation cover 6, a gap is formed between them, ensuring that the distance the pressure-limiting heat insulation cover 6 travels from the step 24 when it rises will not exceed this gap. When the flange 30 of the pressure-limiting heat insulation cover 6 touches the flange 27 of the pot body 14, it will be blocked, providing a safety protection function. After the food is steamed, the pressure-limiting heat insulation cover 6 can be removed to take the food off the new steamer 12.

[0062] Example:

[0063] Figure 33 This is a schematic diagram of the present invention in practice. A novel rice cooker 1 is equipped with a novel steamer basket 12. Four corresponding rope holes 38 are machined on the steamer basket 12. A circular rope can be attached to each rope hole 38 as a handle. The food to be steamed is placed inside the steamer basket 12. After ensuring that water is added to the pot, the pressure-limiting heat-insulating cover 6 can be placed on the step 24 of the novel pot body, and then the power can be turned on to steam the food.
