Description

Intelligent electric cooker, integrated electric valve and filter screen pipeline

Technical Field

The invention relates to the technical field of intelligent household appliances, in particular to an intelligent electric cooker, an integrated electric valve applied to the intelligent electric cooker and a filter screen pipeline.

Background

Rice is usually washed by using an electric rice cooker, and the main purpose of washing the rice is to remove dust in the rice and contaminants adhered to the rice. Secondly, some rice in the market is polished and waxed, which is harmful to human body, and the method is needed to clean the waxiness. Furthermore, in some cases, such as the greengage weather, the rice kernels may have a small mold, and the mold must be washed away by washing, especially the carcinogenic Aspergillus flavus. In addition, starch adhered to rice grains easily generates a large amount of foam during cooking, and the starch overflows a pot cover to pollute the electric cooker.

At present, rice washing of the electric cooker is mainly performed manually, the rice washing is generally performed twice, and about one liter of water is needed for each washing, so that the total water consumption is about two liters. Some people wash vegetables and the like with rice washing water. However, in some cases, the part of rice washing water is poured off in vain, so that water resources are wasted, and the phenomenon is common in cities, students or young people with faster work pace.

In some prior art, a part of dust is removed by blowing, but the effect of blowing and cleaning is still insufficient for dirt stuck on rice grains or polishing wax or mould on rice grains. Experiments prove that the rice washing water is relatively turbid when the rice grains washed by blowing are washed by water for the first time.

In addition, the cleaning pot body is also a little thing, in order to facilitate the surface about the cleaning pot body, can meet a full pan of water usually, 3 ~ 4 litres water approximately, bubble the pot body, and the rice stain bubble on the pot body is soft, and the pot body can be better washed a little. The first washing pass requires one more wash, perhaps half a liter of water. Thus, a pot wash typically requires 3 liters more water. However, sometimes the pot body is forgotten to be washed after being soaked, the pot body needs to be washed only when the next cooking is finished, the hand can be wetted after the pot body is washed, and when the rice is added after the pot body is washed, the hand must be wiped dry firstly to avoid wetting the rice in the rice box, so that the problem is slightly troublesome. Of course, if hot water is not available in winter, hands can be frozen when the rice is washed and the pot is washed.

In addition, the electric cooker can generate a plurality of foams to pollute the cooker cover during the cooking process, and a part of people can not clean the cooker cover every time. In summer, when the temperature is high, pollutants on the pot cover are easy to go moldy and lesion, and the health is affected. Moreover, several liters of water are consumed for cleaning the pot cover, the washing brush and the faucet.

Carefully calculating in this way, it is found that about 6-8 liters of water is needed to be removed when the electric rice cooker is used for cooking rice once and the rice is washed with the pot. At present, the household popularization rate of the electric rice cooker in a big city is very high, and almost families have the electric rice cooker. The single person who lives independently can also buy one electric cooker quickly when the life is stable. Restaurants and canteens basically cook rice by using electric rice cookers at present. In province cities, millions of electric cookers are reserved, so that a great deal of water is consumed for washing rice and a pot every day, and therefore how to avoid water resource waste in the process of cooking by using the electric cookers is a problem to be solved urgently at present.

The intelligent electric cooker provided by the embodiment of the invention utilizes the bottom leakage spraying device, the feeding device or the heating device to remove dust in rice grains and dirt adhered to the rice. The rice washing water is filtered by combining the filtering device, so that the aim of water-saving rice washing is fulfilled. The filtering method is also used for cleaning the pot body and the pot cover. In addition, the water-saving purpose can be achieved by recovering the water evaporated by the electric cooker.

Furthermore, because the rice washing water (or the pot washing water) contains a large amount of starch particles, although the rice washing water (or the pot washing water) is filtered by the filter, the starch particles are deposited in the filter, the rice washing water is easy to be diseased and mildewed, and a filter element of the filter cannot be used quickly and needs to be replaced. Frequent replacement of the filter element is not only troublesome, but also costly. Therefore, the invention adopts three methods to solve the problem that the filter can not be used due to mildew, firstly, the rice grains and larger dust are filtered out by the pre-stage filtration. Secondly, a filtering device capable of backwashing, such as an ultrafiltration membrane, is adopted, so that the filtering effect can be ensured, impurities and impurities can be filtered out, and dirt in the filter can be washed away by a small amount of water by adopting a backwashing technology. The filter is always clean. Adopt the heater (if utilize the pot body heating), will wash water heating to the uniform temperature, can dissolve the wax on the rice in the water, filter the device again, just can get rid of the wax of aquatic. The high-temperature hot water can effectively kill microorganisms such as mould and the like and inhibit the growth of bacteria.

In addition, the invention not only installs the filtering device on the electric cooker, but also optimizes the rice washing process. For example, the floating dust in the rice is removed by wind power, and then the dirt on the rice such as the beaten wax is removed by hot water, so that water or a filter element of the filter can be saved.

In order to facilitate water receiving, the water containing box is usually in a movable form. The water containing box can adopt a mode of barreled water drinker, the water containing barrel is placed in an inverted manner, and the water is controlled to be drained by utilizing the air negative pressure principle. The water containing box is made into a pluggable mode, and the top of the water containing box is provided with the water inlet which is used as a water inlet for injecting water into the water containing box and also used as a water inlet for circularly filtering water by the electric cooker.

The invention can automatically wash the pot and automatically open and close the pot cover, so that the electric cooker can be remotely opened through the Internet even if the pot is forgotten to be washed or the pot cover of the electric cooker is closed when the electric cooker goes out of work.

The invention provides a water-saving intelligent electric cooker which takes a bottom missing spraying device and a rice adding device of the electric cooker disclosed by the inventor in the prior art as a core, and combines a backflushing filtering device and a steam recovery device through air cleaning and water washing, so that the intelligent electric cooker can automatically add rice, wash rice, cook and clean a cooker body and a cooker cover, and has higher intelligent level and excellent water-saving effect. Meanwhile, the invention also improves the electromagnetic valve in the bottom leakage spray device and discloses an integrated electric valve, so that the bottom leakage spray device has a more compact structure.

The pluggable water containing box 89 can be in a horizontal plugging mode (water outlet from the upper part) or in a vertical plugging mode (water outlet from the bottom part).

In the embodiment of the invention, the dust in rice grains and dirt adhered to the rice are removed by using the bottom leakage spraying device, the feeding device or the heating device, and meanwhile, the rice washing water is filtered by combining the filtering device, so that the aim of saving water and washing the rice is fulfilled. The filtering method is also used for cleaning the pot body and the pot cover. In addition, the water-saving purpose can be achieved by recovering the water evaporated by the electric cooker.

Furthermore, because the rice washing water (or the pot washing water) contains a large amount of starch particles, although the rice washing water (or the pot washing water) is filtered by the filter, the starch particles are deposited in the filter, the rice washing water is easy to be diseased and mildewed, and a filter element of the filter cannot be used quickly and needs to be replaced. Frequent replacement of the filter element is not only troublesome, but also costly. Therefore, the invention provides three methods to solve the problem that the filter can not be used due to mildew, firstly, rice grains and larger dust are filtered out by a pre-stage filtration. Secondly, a filtering device capable of backwashing, such as an ultrafiltration membrane, is adopted, so that the filtering effect can be ensured, impurities and impurities can be filtered out, and dirt in the filter can be washed away by a small amount of water by adopting a backwashing technology. The filter is always clean. Moreover, adopt the heater (if utilize the pot body heating), will wash water heating to the uniform temperature, can dissolve the wax on the rice in the water, through straining the device again, just can get rid of the wax of aquatic. The high-temperature hot water can effectively kill microorganisms such as mould and the like and inhibit the growth of bacteria.

In addition, the invention not only installs the filtering device on the electric cooker, but also optimizes the rice washing process. For example, the floating dust in the rice is removed by wind power, and then the dirt on the rice such as the beaten wax is removed by hot water, so that water or a filter element of the filter can be saved. For example, to remove floating dust from rice, the rice can be fed into the pot, and then the bottom leaking and spraying device sprays air to remove the floating dust, or the bottom leaking pipe system of the bottom leaking and spraying device sucks air, and the rice grains are blocked by the rotary filter screen, so that the floating dust is sucked away. The inventor also can submit a patent through the invention, rice and floating dust fall into the bottom of the pot body of the electric cooker by a centrifugal rice feeding method, and floating dust is sucked away by a filter screen in a bottom leakage spraying device, such as a rotary filter screen. Then, a small amount of clean water is injected into the pot body, the water is heated to a proper temperature through the electric cooker so as to dissolve wax or dirt on the rice, and then the water is discharged through the bottom leakage spraying device. Because the floating ash in the rice is drained and the rice is washed by warm water, less water is needed, and the aim of saving water is fulfilled. It is also conceivable to use only warm water washing, instead of the filter device, to assist stirring by air injection. Thus, the cost of the filter is saved, the volume of the electric cooker is reduced, and the trouble of replacing the filter element can be avoided.

At present, an electric cooker is available, in order to wash rice and a pot, a pot body of the electric cooker is in a removable form, and the center of the bottom of the electric cooker is in a flat shape so as to be conveniently and stably placed. The bottom leaking and spraying device is adopted, so that rice can be automatically washed and the pot can be automatically washed, the electric rice cooker can be made into an immovable form, the pot body of the electric rice cooker can be made into a complete arc bottom, the central part is the lowest, and thus, the bottom leaking and spraying device is arranged in the center of the bottom of the pot body, rice washing water can be filtered and dried to the maximum extent, and the aim of saving the rice washing water is fulfilled. Meanwhile, the water-saving device is also beneficial to draining away residues generated in the boiler washing process, thereby achieving the purpose of water saving.
