Description

rice cooker

technical field

The utility model relates to a kitchen appliance, in particular to an electric rice cooker.

Background technique

Panasonic rice cooker patent 2004100055886 mentions that water passes through a steam generating device and a steam heating device, and finally becomes high-temperature superheated steam, which is introduced into the rice cooker, so that the upper layer of rice does not dry out, and promotes the paste of the rice, improving cooking. performance. This patent adopts two heating methods. First, the steam generating device is used to heat the water into saturated steam, and then the steam heating device installed on the upper cover is used to convert the saturated steam into superheated steam, which has the following disadvantages:

1. It is not energy-saving, you can’t heat as much steam as you need, every time you heat the water in the container.

2. The amount of steam entering the pot cannot be accurately controlled, for example: when the steam required in the pot is sufficient, but the boiling water generated by the steam generating device is still producing water vapor, so the amount of steam cannot be controlled.

3. Since it needs to be heated twice, the heat insulation requirements of the rice cooker related parts and materials are increased, and the cost is increased.

4. Since the water in the water container will turn into boiling water, the temperature of the water container will also become very high. When opening the cover, there is an additional component that should be protected from scalding.

The utility model isolates the cold water and the hot water, the lower part of the heating device 7 only heats the water in the hot water area, and the upper part is used for heating the water mist, so as to achieve the effect of rapidly generating steam, and can generate superheated steam. Moreover, the water level is constant, and the amount of steam generated at one time is constant. After the heating steam generating device is stopped, no steam can be generated quickly, so as to achieve energy saving effect.

The base 3 in this embodiment is provided with a mounting bracket 6, and an accommodation cavity 15 for accommodating the aforementioned steam generating device is formed between the installation bracket 6 and the middle plate 5, and the heating device 7 is installed in the accommodation cavity 15, so that The water in the chamber 15 can cover the bottom of the heating device 7, so that the water mist can be formed by heating.

The water inlet device in this embodiment includes a water container 10 with a closed upper end and a water outlet at the lower end. The water container 10 is installed on the outside of the mounting bracket 6 . The bottom is connected, and part of the water is introduced into the accommodating cavity 15 through the external water container 10, and part of the water is heated to achieve the purpose of quickly generating steam.

The water outlet of the water container 10 described in this embodiment is provided with a sealing plug assembly, and the mounting bracket 6 is provided with a bump 12 for jacking up the sealing plug assembly. When the water container 10 is mounted upside down on the mounting bracket 6, The protrusion 12 pushes up the sealing plug assembly, and the water in the water container 10 flows out to the accommodating cavity 15 . The utility model seals the water outlet through the sealing plug assembly. When the water container 10 is installed upside down, the water will not flow out from the water outlet. Inside the chamber 15.

The water outlet position of the water container 10 described in this embodiment is set higher than the lower part of the heating device, and the height of the water outlet position can control the water level in the storage chamber. By using the principle of atmospheric pressure, the water level in the storage chamber 15 is kept constant, and the storage chamber 15 is kept constant. The water level in the cavity 15 covers the lower part of the heating device 7, so that heating forms water mist.

The sealing plug assembly described in this embodiment includes a plug seat 13, a water outlet is opened in the plug seat 13, a sealing plug 8 is installed at the water outlet, and an outer end of the sealing plug 8 and the plug seat 13 are provided. Spring 14 is arranged, and its inner end is provided with the seal piece 9 that water outlet is sealed.
