Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electric rice cookers, and in particular relates to air-cooled electric rice cooker equipment. Background Art
[0002] A large amount of rice bubbles will be generated when cooking rice or porridge with an electric rice cooker. In order to prevent the rice bubbles from overflowing, the prior art has proposed many solutions. The most common solution is to install a steam valve or a similar exhaust structure on the lid of the rice cooker to guide the steam generated during the heating process of the rice cooker through the steam valve. The steam valve itself has a certain anti-overflow capability and can reduce the chance of rice soup overflowing. However, when cooking porridge with a large amount of rice or cooking some ingredients that are easy to become sticky, there will still be overflow. In view of the anti-overflow defect of the steam valve, a bubble-breaking wheel or a blowing device is added to the steam valve, which can improve the anti-overflow capability of the steam valve to a certain extent. However, it is affected by factors such as the heating power of the rice cooker and the quality of the rice, and the overflow problem cannot be completely solved. In addition, the rice soup remains in the steam valve, which increases the difficulty of cleaning the steam valve.
[0003] After searching, it was found that the authorization publication number "CN210169714U" discloses "an anti-overflow rice cooker, which belongs to the field of kitchen appliances and solves the problems of poor use effect and inconvenient cleaning of the anti-overflow structure on the existing rice cookers. The anti-overflow rice cooker of the utility model includes a cooker body and a cooker cover, and the cooker cover is covered on the cooker body to form a cooking cavity. The cooker cover is provided with an air intake channel, an exhaust channel and a fan. The air intake channel and the exhaust channel are independently arranged and connected to the outside world. The fan is used to introduce outside air from the air intake channel into the cooking cavity for breaking bubbles. The utility model proposes the concept of air-cooled bubble breaking, that is, using cold air to directly break bubbles in the cooking cavity. The bubble breaking effect is stable and reliable, and can completely solve the anti-overflow problem of the rice cooker."
[0004] like Figure 1As shown, the above patent includes a pot body 100 and a pot cover 200. The pot cover 200 is covered on the pot body 100 to form a cooking cavity 110. The pot cover 200 is provided with an air intake channel, an exhaust channel and a fan 400. The air intake channel and the exhaust channel are independently arranged and connected to the outside. The fan 400 is used to introduce external air from the air intake channel into the cooking cavity 110 for breaking bubbles. The fan 400 is used to introduce outside air into the cooking cavity 110 from the air inlet passage. The kinetic energy of the airflow can directly break some bubbles. For bubbles with a solid surface, since the temperature of the outside air is much lower, the surface temperature of these bubbles drops sharply after contacting the cold air, causing the bubbles to shrink violently and break. Since the outside air enters the cooking cavity 110 from top to bottom, when most of the rice bubbles in the cooking cavity 110 are broken, the outside air can directly contact the surface of the rice soup solution, causing the surface temperature of the rice soup solution to drop sharply, thereby reducing the activity of the surface protein solution, and effectively inhibiting the generation of rice bubbles. By maintaining this air-cooled state, only a small amount of small bubbles will be generated during the cooking process, and the small amount of small bubbles will not have the opportunity to overflow from the air inlet passage and the exhaust passage. This not only completely solves the problem of preventing the rice cooker from overflowing, but also greatly reduces the risk of bubbles entering the air inlet passage, the exhaust passage and the like. and the probability of contact with the fan 400. There is no or only a small amount of rice soup residue on the fan 400 and the pot cover 200, which is convenient for users to clean, can reduce the frequency of cleaning, and improve the use experience; since the pot cover 200 is provided with an independent air intake channel and an exhaust channel, the outside air is introduced into the cooking cavity 110 from the air intake channel, and the hot air and water vapor in the cooking cavity 110 are discharged through the exhaust channel. On the one hand, the circulation efficiency of the air flow inside and outside the cooking cavity 110 can be improved, the air intake efficiency is high, and the outside air is stably and continuously introduced into the cooking cavity 110 to participate in breaking bubbles, and the use of a small fan can achieve the effect of efficient bubble breaking; on the other hand, the outside air is introduced into the cooking cavity 110 to participate in breaking bubbles and then discharged with the hot air. The outside air only reduces the surface temperature of the rice soup solution and will not penetrate into the inside of the rice soup, and the heating effect will not be reduced due to the introduction of cold air.
[0005] Combined with the above records and Figure 1 It can be directly and undoubtedly concluded that the above-mentioned rice cooker dissipates heat based on air cooling, thereby achieving the technical effect of preventing overflow and bubble breaking. However, in the above-mentioned patent, when the fan guides the outside air into the interior of the rice cooker, the gas eventually overflows from the bottom to the top. At this time, the gas overflowing from the rice cooker is high-temperature steam. At the same time, the high-temperature steam is also easy to overflow upward with the liquid food in the rice cooker, which can easily scald the user, and it has certain safety hazards.

The above gap is left between the base 102 and the kitchen countertop, and then the outside air can enter or be discharged from the bottom;
[0051] See also Figure 3 The exhaust and pressure relief mechanism 3 is arranged on the pot cover 101 to achieve exhaust and pressure relief. The exhaust and pressure relief mechanism 3 includes an exhaust valve 301 and a pressure relief valve 302 arranged in parallel on the pot cover 101, thereby achieving exhaust and pressure relief.
[0052] See also Figure 4 The control panel assembly 4 is arranged on the pot cover 101 to realize the cooking function setting and intelligent control. The control panel assembly 4 has function buttons for users to operate. The function buttons can be virtual buttons for touch or physical buttons for operation. Through the function buttons, users can select different cooking modes. At the same time, the control panel assembly 4 is provided with a single-chip microcomputer for realizing the automatic control function, and the single-chip microcomputer is set with a program for triggering intelligent control;
[0053] See also Figure 4 and Figure 5 The air circulation channel 8 is provided on the base 102 to realize air circulation. The air circulation channel 8 has at least an air inlet end 801 for realizing air entering from the bottom, an air outlet end 802 for realizing air discharge from the bottom, and a ventilation area for realizing internal air circulation. At least an A ventilation area 803, a B ventilation area 805, and a C ventilation area 804 for realizing air circulation are provided between the liner 103 and the base 102.

[0057] The induction valve 2, the cooling fan 6 and the damper plate 7 are all electrically connected to the control board assembly 4 to achieve automatic control;
[0058] Specific:
[0059] The above-mentioned single chip microcomputer is provided with a standard threshold range A of air pressure. When the induction valve 2 senses the air pressure in the pot body 1, it obtains the air pressure sensing value B. The single chip microcomputer compares the standard threshold range A of air pressure with the air pressure sensing value B. When the air pressure sensing value B exceeds the standard threshold range A of air pressure, the control board component 4 will intelligently close the damper plate 7, and then isolate the air circulation between the air inlet end 801 and the air outlet end 802. At the same time, the control board component 4 will intelligently start the cooling fan 6 to operate. The cooling fan 6 introduces the outside air into the air inlet end 801 from the bottom, and then circulates through the ventilation area A 803, the ventilation area B 805 and the ventilation area C 804 in turn. Finally, the gas is discharged to the bottom through the gas outlet 802, and the gas is discharged outward. Since the gas is discharged outward from the bottom, it will not rush upward to scald the user, and has a high safety performance. In the above-mentioned air circulation process, the high-pressure steam in the pot body 1 is discharged outward synchronously, and the temperature in the pot body 1 gradually decreases until the hot air in the pot body 1 reaches the normal range. At this time, the induction valve 2 obtains the air pressure sensing value C. At this time, the air pressure sensing value C is lower than the air pressure standard threshold range A. The control board component 4 intelligently controls the air damper baffle 7 to open and close the cooling fan 6 to stop it from moving, and finally realizes intelligent control. The above-mentioned concept is the triggering intelligent control program set in the single-chip microcomputer;
[0060] See also Figure 5 The heating component 5 is arranged in the base 102 and located at the lower side of the inner pot 103 to achieve food heating. It adopts conventional technical means in the prior art, so it will not be repeated here;
[0061] The working principle and use process of this utility model:
[0062] When the user puts the food into the inner pot 103, and then connects the power supply terminal 105 to the external power supply through the connecting cable, and then powers on, the user selects the cooking mode in the control panel component 4 to cook, and the heating component 5 works to heat the inner pot 103. Under the interaction of the hot air and the food, a large amount of hot air and air pressure will be generated in the pot body 1. At this time, the pressure relief valve 302 will start to discharge the corresponding air pressure. At this time, there is still a large amount of hot air in the pot body 1. When the sensing valve 2 senses the air pressure in the pot body 1, it obtains the air pressure sensing value B. The single chip compares the air pressure standard threshold range A with the air pressure sensing value B. When the air pressure sensing value B exceeds the air pressure standard threshold range A, the control panel component 4 will intelligently close the air door baffle 7, thereby isolating the air circulation between the air inlet end 801 and the air outlet end 802. The control panel assembly 4 will intelligently start the cooling fan 6 to operate. The cooling fan 6 introduces external air from the bottom into the air inlet end 801, and then circulates through the A ventilation area 803, the B ventilation area 805 and the C ventilation area 804 in turn, and finally is discharged to the bottom through the air outlet end 802, so that the gas is discharged outward. Since the gas is discharged outward from the bottom, it will not rush upward to scald the user, and has a higher safety performance. In the above-mentioned air circulation process, the high-pressure steam in the pot body 1 is discharged outward synchronously, and the temperature in the pot body 1 gradually decreases until the hot air in the pot body 1 reaches the normal range. At this time, the induction valve 2 obtains the air pressure sensing value C. At this time, the air pressure sensing value C is lower than the air pressure standard threshold range A, and the control panel assembly 4 intelligently controls the damper plate 7 to open and close the cooling fan 6 to stop it from moving;
