[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0026] Please also read Figures 1 to 4 The utility model discloses an electric rice cooker, which comprises an electric rice cooker shell 10, an electric rice cooker inner pot 20 and a heating plate 30 capable of generating steam. The heating plate 30 capable of generating steam is arranged at the bottom of the electric rice cooker shell 10, the electric rice cooker inner pot 20 is placed in the electric rice cooker shell 10 and supported on the heating plate 30 capable of generating steam. The water vapor generated on the heating plate 30 capable of generating steam is transported to the electric rice cooker inner pot 20, and the water vapor can be used to heat the rice in the electric rice cooker inner pot 20 to form steam supplementary cooking.
[0027] The heating plate 30 capable of generating steam in the present solution comprises a heating plate body 1, a heating component 2 and a steam generating component 3. The heating component 2 and the steam generating component 3 are both arranged on the heating plate body 1. The heating component 2 is used to heat the heating plate body 1. Under the heating of the heating plate body 1 and / or the heating component 2, the steam generating component 3 is used to evaporate water into water vapor and transport it to the inner pot 20 of the electric rice cooker. With such a design, on the one hand, the water vapor generated by the steam generating component 3 can be used to heat the rice in the inner pot 20 of the electric rice cooker to form steam supplementary cooking, thereby effectively improving the taste of the rice; on the other hand, steam can be generated by heating the heating component (that is, heating the heating plate 30), which is equivalent to saving a steam generator while generating steam when necessary, thereby ensuring that the electric rice cooker can improve the taste of the rice at a low cost.
[0028] Among them, in this scheme, you can choose to use steam supplementary cooking or not according to the user's usage needs. When steam supplementary cooking is needed, water is supplied to the steam generating component 3, and the steam generating component 3 generates water vapor to achieve steam supplementary cooking; when steam supplementary cooking is not needed, water is not supplied to the steam generating component 3, and the steam generating component 3 does not generate water vapor.
[0029] Among them, under the heating of the heating disk body 1 and / or the heating component 2, the steam generating component 3 is used to evaporate water into water vapor, which specifically includes: under the heating of the heating disk body 1, the steam generating component 3 is used to evaporate water into water vapor, or, under the heating of the heating component 2, the steam generating component 3 is used to evaporate water into water vapor, or, under the heating of the heating disk body 1 and the heating component 2, the steam generating component 3 is used to evaporate water into water vapor. This embodiment takes the example of the steam generating component 3 evaporating water into water vapor under the heating of the heating disk body 1.
[0030] In some embodiments, the heating component 2 is a heating tube, which is arranged in a ring shape around the outer periphery of the heating plate body 1, and the steam generating component 3 is a metal tube, which is used to evaporate water into water vapor and transport it to the inner pot 20 of the electric rice cooker, and the metal tube is arranged in a ring shape around the outer periphery of the heating plate body 1. With such a design, since the heating tube is arranged in a ring shape on the heating plate body 1, the heating effect of the heating tube on the heating plate body 1 is more uniform.
[0031] Furthermore, the metal tube is arranged around the outer circumference of the heating tube and is arranged close to the heating tube. With such a design, since the metal tube is arranged around the outer circumference of the heating tube, the metal tube can have a longer evaporation space; and since the metal tube is arranged close to the heating tube, the heating effect of the metal tube is better, so that the metal tube has a better evaporation effect.
[0032] It is understandable that in other embodiments, a design in which the metal tube is arranged inside the heating tube may also be adopted, which is not limited here.
[0033] Considering that the water vapor evaporated in the metal tube is transported to the inner pot 20 of the electric rice cooker to cook rice, preferably, the metal tube is a stainless steel tube. Since the material of stainless steel will not precipitate harmful substances at high or low temperatures, the material performance is quite stable and will not cause any pollution. In addition, the stainless steel material can effectively inhibit the growth of bacteria and microorganisms, ensure the cleanliness and sanitation of water quality, and ensure that healthy and clean rice can be cooked.
[0034] In some embodiments, in order to realize the installation of the heating tube and the metal tube on the heating plate body 1, the heating plate body 1 is provided with a first installation cavity 11 and a second installation cavity 12, the heating tube is passed through the first installation cavity 11 and is attached to the inner wall surface of the first installation cavity 11, and the metal tube is passed through the second installation cavity 12 and is attached to the inner wall surface of the second installation cavity 12. With such a design, on the one hand, since the heating tube is installed in the first installation cavity 11 and is attached to the inner wall surface of the first installation cavity 11, the contact area between the heating tube and the heating plate body 1 can be increased, thereby enhancing the heat conduction effect between the heating tube and the heating plate body 1; on the other hand, since the metal tube is passed through the second installation cavity 12 and is attached to the inner wall surface of the second installation cavity 12, the contact area between the heating plate body 1 and the metal tube can be increased, thereby enhancing the heat conduction effect between the heating plate body 1 and the metal tube.
[0035] Furthermore, the heating tube has a first connection end 21 and a second connection end 22 connected to the power supply, and the first installation cavity 11 is provided with a first avoidance opening 111 and a second avoidance opening 112. The first connection end 21 passes through the first avoidance opening 111 to connect to the power supply, and the second connection end 22 passes through the second avoidance opening 112 to connect to the power supply.
[0036] Furthermore, the metal tube has a water inlet end 31 connected to a water source and a steam outlet end 32 for conveying water vapor into the inner pot 20 of the electric rice cooker. The second mounting cavity 12 has a third avoidance opening 121 and a fourth avoidance opening 122. The water inlet end 31 passes through the third avoidance opening 121 to be connected to a water source, and the steam outlet end 32 passes through the fourth avoidance opening 122 to convey water vapor into the inner pot 20 of the electric rice cooker.
[0037] Furthermore, in order to transport the water vapor on the metal tube to the inner pot 20 of the rice cooker, the heating plate 30 capable of generating steam also includes a steam delivery pipe 4, one end of the steam delivery pipe 4 is connected to the steam outlet end 32, and the other end of the steam delivery pipe 4 extends to communicate with the inner pot 20 of the rice cooker.
[0038] Preferably, the steam delivery tube 4 is a silicone tube. With such a design, on the one hand, the silicone tube is resistant to high temperatures and can meet the requirements for delivering high-temperature water vapor; on the other hand, the silicone tube is relatively soft and can be deformed to suit the internal shape of the rice cooker.
[0039] Furthermore, the electric rice cooker further comprises a water tank (not shown) and a water pump (not shown), the water tank is connected to the steam generating component 3 through a pipeline, and the water pump is used to pump the water in the water tank to the steam generating component 3. With such a design, by providing the water tank and the water pump, the steam generating component 3 can be continuously supplied with water, so that the steam generating component 3 can continuously generate water vapor to meet the supplementary steaming requirement.
[0040] It is understandable that the steam generating component 3 may be provided with a water storage chamber to directly heat the steam generating component 3 to generate continuous steam, which is not limited herein.
[0041] The utility model provides an electric rice cooker, which is provided with a heating plate 30 capable of generating steam, including a heating plate body 1, a heating component 2 and a steam generating component 3. The heating component 2 and the steam generating component 3 are both arranged on the heating plate body 1. The heating component 2 is used to heat the heating plate body 1. Under the heating of the heating plate body 1 and / or the heating component 2, the steam generating component 3 is used to evaporate water into water vapor and transport it to the inner pot 20 of the electric rice cooker. With such a design, on the one hand, the water vapor generated by the steam generating component 3 can be used to heat the rice in the inner pot 20 of the electric rice cooker to form steam supplementary cooking, thereby effectively improving the taste of the rice; on the other hand, steam can be generated by heating the heating component (that is, heating the heating plate 30), which is equivalent to saving a steam generator while generating steam when necessary, thereby ensuring that the electric rice cooker can improve the taste of the rice at a low cost.
[0042] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
