Description

A new type of electromagnetic heating rice cooker

technical field

The invention relates to the field of electric rice cooker manufacture, in particular to a novel electromagnetic heating type rice-draining electric cooker.

Background technique

There is an electromagnetic heating rice-leaching rice cooker on the market, as shown in Figure 1. The main structure includes a shell (1), an outer pot (2), a rice cooker (3) with holes distributed on the bottom and side walls, and an electromagnetic heating coil (4). ) and the pot cover (5), which are characterized in that the inner layer is the rice pot and the outer layer is the outer pot. There is a space between the bottom of the rice pot and the bottom of the outer pot. Add an appropriate amount of water to the pot, so that the water surface is higher than the rice surface by an appropriate distance. As the rice cooks, part of the water is absorbed and evaporated by the rice, so that the water surface of the rice soup is lowered and gradually lower than the upper rice surface of the half-cooked rice. The remaining part of the rice soup in the outer pot continues to boil to steam the rice in the rice pot until the rice is cooked. The biggest shortcoming of this structure is that the rice soup cannot be completely separated from the rice. It is because the rice soup cannot be completely separated from the rice. The upper layer of the rice is loose, and the lower layer is still moist, which cannot achieve the effect of high-quality rice.

SUMMARY OF THE INVENTION

The object of the present invention is to solve the practical defects of the existing electromagnetic heating rice-draining rice cooker, and a novel electromagnetic heating-type rice-draining rice cooker is provided, which can make high-quality rice-draining rice in which the rice and the rice soup are completely separated.

A new type of electromagnetic heating rice-leaching rice cooker mainly includes a lid, a valve opening device, a valve opening relay rod, a rice pot with a rice soup leak hole on the bottom, a rice soup valve placed on the rice soup leak hole, and an independent built-in rice soup. Basin, outer pot, electromagnetic heating coil and control system.

The top and lower ends of the valve-opening relay rod are also provided with a relay permanent magnet and a valve-opening permanent magnet, respectively. The side wall of the rice cooker is provided with a guide groove for the valve-opening relay rod to move up and down freely, and the valve-opening relay rod is placed in the guide. in the slot.

The groove on the upper part of the valve-opening relay rod can make the valve-opening relay rod hang on the upper edge of the guide groove to form the initial position of the valve-opening relay rod.

The electric drive mechanism of the valve opening device can act on the relay permanent magnet on the valve opening relay rod. The valve opening relay rod relays and transmits the valve opening magnetic effect after the valve opening device is energized. The lower end of the valve opening relay rod is close to The rice soup valve is opened by the magnetic attraction of the valve-opening permanent magnet.

When the valve opening device is powered on, the magnetic thrust can act on the relay permanent magnet of the valve opening relay rod through the lower bottom plate of the pot cover, so that the valve opening relay rod is separated from the initial position of the suspension and falls due to gravity to complete the valve opening magnetic force effect. relay transmission.

The valve-opening relay rod falls, the valve-opening permanent magnet at the lower end of the valve-opening relay rod is close enough to the valve permanent magnet on the rice soup valve, and the valve opening permanent magnet generates enough magnetic attraction to the valve permanent magnet, causing rice soup The valve deviates from the closed position of the rice soup hole and opens, and the rice soup in the rice pot is discharged into the independent built-in rice soup basin below through the leakage hole, so as to realize the complete separation of the rice soup and the rice.

The rice soup valve includes a valve permanent magnet, a sealing ring and a positioning column. When the rice soup valve is placed on the rice soup leakage hole according to its own gravity, the outer wall surface of the positioning column forms a sliding fit with the hole wall of the rice soup leakage hole, and the sealing The ring is close to the edge of the leakage hole of the rice soup to form a seal for the leakage hole of the rice soup.

The valve opening device is arranged in the inner cavity of the interlayer of the pot cover, and the valve opening device transmits the magnetic force to the valve opening relay rod through the pot mouth of the outer pot through the inner bottom plate of the pot cover and the steam condensate separator, so that the valve is opened. The device is completely isolated from the water and steam for cooking.

The electric drive mechanism on the valve opening device can be either a static structure composed of an iron core and an electromagnetic coil, or a movable structure composed of an electromagnet and a permanent magnet that controls extension or retraction thereof.

The two terminals of the control system outputting the valve opening signal can be electrically connected to the two terminals of the electromagnetic coil, or can be electrically connected to the two terminals of the electromagnet.

When the valve opening device is energized, the electromagnetic coil can send out magnetic lines of force at the end of the iron core; when the valve opening device is de-energized, the magnetic lines of force disappear.

When the valve opening device is energized, the iron core of the electromagnet can drive the permanent magnet fixed on the iron core head to extend; the valve opening device is de-energized and the permanent magnet retracts.

The rice soup pot and the rice pot are sequentially entered through the mouth of the outer pot, and are built into the outer pot. The rice soup pot is placed on the bottom of the outer pot through the supporting feet, and the rice pot is suspended on the upper edge of the outer pot. , to form a package, the rice pot is on the top, and the rice soup pot is in the middle.

The electromagnetic heating coil only acts on the outer pot, not the rice pot. The rice pot and the rice and water in it are the steam generated by the boiling of the water in the outer pot to realize the cooking and heating.

It should be noted:

The lower bottom plate of the lid, the steam condensing baffle of the lid, the guide groove of the rice cooker and the valve-opening relay rod must be made of non-magnetic or weak magnetic stainless steel, or aluminum and alloy, or copper and alloy materials; relay permanent magnets , Both the valve opening permanent magnet and the valve permanent magnet need to use high temperature resistant strong magnets.

The invention is not only applicable to the electromagnetic heating type electric rice cooker, but also can be used for the electric heating plate heating type electric rice cooker.

The beneficial effects of the present invention are as follows:

1. This new type of electromagnetic heating rice-leaching rice cooker develops a valve opening device by sealingly placing it in the inner cavity of the pot lid, and then opens the rice soup valve through the relay and transmission of the valve opening relay rod located in the outer pot. It solved the obstacle that the magnetic force could not act through the bottom and side walls of the magnetic outer pot, effectively solved the problem of using the electromagnetic heating type rice cooker to make rice soup and rice completely separate and draining the rice, so that the electromagnetic heating type rice cooker can Makes high-quality drained rice with very loose top and bottom layers.

2. This new type of electromagnetic heating rice-leaching rice cooker, its outer pot, rice pot, rice soup pot, valve opening relay rod, rice soup valve, etc. can be washed with water at will, no need to be careful.

3. This new type of electromagnetic heating rice-draining rice cooker, in addition to cooking and draining rice, can realize ordinary rice, porridge, soup or other functions of ordinary rice cookers only by using the outer pot when it is not put into the rice pot and rice soup pot. cooking function.
