Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example one

The embodiment provides a cooking appliance for cooking food materials. The following further details the specific embodiment of the present embodiment by taking the electric cooker as an example.

The rice cooker is used for accelerating the water absorption speed and the water absorption effect of rice grains, reducing the time for manufacturing rice by the rice cooker and improving the taste of the manufactured rice. Simultaneously, this electric rice cooker can also improve the pressure of culinary art intracavity for the material of eating can be selective cooks under the pressure culinary art state, when reducing the culinary art. During the culinary art, electric rice cooker enters into the negative pressure culinary art state earlier and cooks, improves the grain of rice speed of absorbing water, and the grain of rice absorbs water and accomplishes the back, and the user can select the ordinary pressure culinary art or have the pressure culinary art, and when selecting the ordinary pressure culinary art, the culinary art chamber communicates with external world for the atmospheric pressure in the culinary art chamber is unanimous with external ordinary pressure, and when selecting the pressure culinary art, the culinary art chamber seals with external world or stage nature, makes the atmospheric pressure in the culinary art chamber be higher than external ordinary pressure, eats.

Specifically, referring to fig. 1 to 7, the electric rice cooker includes a cooker body 10 and a cover body 20, wherein the cooker body 10 includes an outer cooker and an inner container which is placed in the outer cooker and can be taken out, the cover body 20 is hinged to the cooker body 10, and the cover body 20 can seal the inner container to form a cooking cavity 11 for cooking rice. The lid 20 is provided with a vacuum device for forming a negative pressure environment in the cooking chamber 11 and a steam valve 30.

Further, the cover 20 is provided with an air exhaust hole for exhausting air, the vacuum device can be directly connected with the air exhaust hole to exhaust the air in the cooking cavity 11, or the air pipe can be connected with the vacuum device and the air exhaust hole to form an air exhaust pipeline to exhaust the air in the cooking cavity 11.

The steam valve 30 has an exhaust passage 31 for communicating the outside with the cooking chamber 11, the exhaust passage 31 is provided with a weight ball 32, and the cover 20 is provided with a driving device for driving the weight ball 32.

When the cooking cavity 11 of the electric cooker is in a negative pressure state, the rice grains can be quickly extruded by the gas inside the rice grains under the action of the pressure difference, so that the water absorption speed of the rice grains is accelerated, and the water absorption effect of the rice grains is improved. The water absorption speed of the rice grains is increased, so that the time for making rice by the electric rice cooker is reduced, the water absorption effect of the rice grains is improved, and the taste of the rice made by the electric rice cooker is improved.

When the vacuum device is in a working state, namely the cooking utensil is in a negative pressure state, at the moment, the heavy ball 32 blocks the outlet end of the exhaust channel 31 by means of the gravity of the heavy ball to seal the exhaust channel 31, so that the external gas is prevented from entering the cooking cavity 11 from the exhaust channel 31 to influence the work of the vacuum device.

After the rice grains absorb water, if normal pressure cooking is selected, in order to ensure normal exhaust in the cooking cavity 11 during the cooking process, the exhaust passage 31 needs to be opened to exhaust the gas in the cooking cavity 11, so as to maintain the cooking cavity 11 in a normal pressure state. That is, when the rice cooker cooks under normal pressure, the exhaust passage 31 is kept open. At this time, the driving means drives the heavy ball 32 to move to open the exhaust passage 31, so that the cooking chamber 11 can be normally exhausted.

Specifically, the driving device comprises an electromagnetic push rod 21 and a strong magnet 22 at the front end of the push rod 21, when the electric rice cooker enters a normal pressure cooking state, the electromagnetic push rod 21 is electrified to push the strong magnet 22 at the front end of the push rod 21 to be close to the heavy ball 32, and the heavy ball 32 is attracted by the magnetic force of the strong magnet 22 to move so as to open the exhaust channel 31. Thus, the driving device does not need to be in direct contact with the heavy ball 32, and the installation space inside the cover body 20 is saved. Meanwhile, the driving device is not in contact with the heavy ball 32, which means that abrasion between the heavy ball 32 and the driving device is avoided, so that on one hand, the service lives of the driving device and the heavy ball 32 are prolonged, on the other hand, the roundness of the heavy ball 32 after long-time use can be effectively ensured, and then, the sealing effect of the heavy ball 32 on the exhaust channel 31 is ensured.

Further, in this embodiment, the outlet end of the exhaust channel 31 has a concave heavy ball 32 mounting position 35, and the heavy ball 32 is naturally located in the mounting position 35 to close the exhaust channel 31. Through set up the heavy ball 32 installation position 35 of indent at exhaust passage 31's exit end, heavy ball 32 can be stable under the action of gravity fall into installation position 35 in, realize the sealed to exhaust passage 31, certain limiting displacement has been played heavy ball 32 to the installation position 35 lateral wall of indent, when cooking utensil carries out the negative pressure culinary art, heavy ball 32 is difficult to rock, and the change position has then improved heavy ball 32 to exhaust passage 31's sealed effect. When the driving device works, the heavy ball 32 can move upwards for a certain distance from the wall surface of the concave mounting position 35 in an outward inclined mode, so that the exhaust channel 31 is opened, when the driving device does not work, one part of the heavy ball 32 is still located in the concave mounting position 35, and the heavy ball 32 can automatically roll into the mounting position 35 under the action of self gravity to seal the exhaust channel 31. The concave installation position 35 is arranged at the outlet end of the exhaust channel 31, so that when the cooking utensil switches between a negative pressure working state and a normal pressure working state, the moving position of the heavy ball 32 is more controllable, and the moving accuracy is higher.

Generally, in the present embodiment, the vacuum device employs the vacuum pump 34, the vacuum pump 34 has a small volume and occupies a small space on the lid 20, and the vacuum pump 34 has a valve inside to prevent external air from reversely entering the cooking cavity 11 from the vacuum pump 34.

Since the water absorption stage of rice grains is usually at the beginning of the cooking process, the negative pressure cooking state of the rice cooker is before the normal pressure state. When the electric cooker is to enter a negative pressure cooking state, the electromagnetic push rod 21 drives the strong magnet 22 to be far away from the heavy ball 32, the magnetic force generated by the strong magnet 22 is not enough to overcome the gravity of the heavy ball 32 rolling into the installation position 35, the heavy ball 32 can enter the installation position 35 under the action of the gravity of the heavy ball to seal the exhaust passage 31, other external force is not required to be applied, the scheme does not need energy consumption, and the use cost of a cooking appliance is reduced.

In order to improve the magnetic attraction of the strong magnet 22 to the heavy ball 32, the inside of the heavy ball 32 is made of metal or magnet material, and the metal or magnet is arranged inside the heavy ball 32, so that the magnetic attraction of the strong magnet 22 to the heavy ball 32 can be improved, and the exhaust channel 31 can be opened by the heavy ball 32 moving stably and quickly.

Since the heavy ball 32 cannot ensure one hundred percent roundness when manufacturing the heavy ball 32 due to the current machining technique, when the roundness of the heavy ball 32 is wrong, the heavy ball 32 seals the exhaust passage 31, and occasionally leaks. That is, the exhaust passage 31 is not completely sealed by the weight ball 32, and the external air can enter the cooking chamber 11 through the gap between the weight ball 32 and the outlet end of the exhaust passage 31. So, improved the load of vacuum device evacuation, the negative pressure environment that cooks the intracavity formation is unstable, influences electric rice cooker's practical application effect.

Furthermore, a soft rubber pad is arranged on the mounting position 35 of the heavy ball 32 at the outlet end of the exhaust channel 31, and the soft rubber pad can be a silica gel pad or a sealing ring. Set up soft cushion or set up the sealing washer at exhaust passage 31's exit end in the installation on the internal wall face, heavy ball 32 is when installation position 35, heavy ball 32's gravity is pressed on soft cushion or sealing washer, can make soft cushion and sealing washer produce and warp, the soft cushion and the sealing washer after the deformation can be better laminate with heavy ball 32 sphere, thereby form sealedly between heavy ball 32 and exhaust passage 31, in order to solve heavy ball 32 circularity not high or heavy ball 32 surface have the not good problem of heavy ball 32 and exhaust passage 31 leakproofness that little concavity leads to.

In some schemes, the outer portion of the heavy ball 32 is sleeved with the elastic sleeve 321, so that the surface of the heavy ball 32 can be deformed by itself to be in sealing fit with the outlet end of the exhaust channel 31 under the condition that the heavy ball 32 is pressed, and the sealing effect is improved.

Generally, elastic sleeve 321 can adopt the silica gel material, and the plasticity of silica gel material is good, and chemical property is stable, meets water and is difficult to corrode, and elastic sleeve 321 adopts the silica gel material, when the pressurized, can be fine self-deformation in order to seal the laminating with exhaust passage 31's exit end, improves sealed effect.

The thickness of elastic sleeve 321 is preferably between 1mm and 5mm, for example 1mm, 2mm, 2.3mm, 3mm, 4mm, 5mm, when the thickness of elastic sleeve 321 is less than 1mm, the deformable allowance of elastic sleeve 321 is less, can not be fine carry out oneself and warp in order to laminate exhaust passage 31's exit end, when the thickness of elastic sleeve 321 is greater than 5mm, the thickness of elastic sleeve 321 is too big, because elastic sleeve 321 is non-magnetic, the magnetic attraction of strong magnet 22 to heavy ball 32 can be influenced to too thick elastic sleeve 321, lead to heavy ball 32 to descend to the magnetic sensitivity of strong magnet 22, influence strong magnet 22 to attract heavy ball 32 and open exhaust passage 31.

In another case, after the rice grains are completely absorbed, the pressure cooking state is selected, and the cooking chamber 11 is ensured to be closed or closed in stages, so that the steam generated by heating in the cooking chamber 11 can be kept in the cooking chamber 11 to increase the pressure in the cooking chamber 11. At this moment, the driving device does not work, the cooking cavity 11 and the outside are in a closed state, along with the temperature in the cooking cavity 11 is higher and higher, water in the cooking cavity 11 boils and generates water vapor, the pressure in the cooking cavity 11 is improved due to the water vapor, the pressure is higher than the normal pressure state, and then the food materials are cooked in the environment higher than the normal pressure.

In the embodiment, the exhaust passage 31 is sealed by the heavy ball 32, the pressure in the cooking cavity 11 has the highest threshold, and when the pressure generated by the pressure difference between the cooking cavity 11 and the outside is greater than the self-gravity of the heavy ball 32, the pressure in the cooking cavity 11 pushes the heavy ball 32 open to exhaust a part of gas, thereby ensuring the balance of forces. So, can guarantee that the pressure of culinary art chamber 11 is in controllable state, factor of safety is high during electric rice cooker culinary art.

In some cases, for example, the cooking chamber 11 needs to be opened after the cooking is finished, and at this time, the gas in the cooking chamber 11 needs to be exhausted to reduce the pressure in the cooking chamber 11 to make it reach the normal pressure state, so as to ensure that the pan is not fried when the cover is opened. In the embodiment, the heavy ball 32 is driven by the driving device to move to open the exhaust channel 31, so that exhaust can be performed, the pressure state is relieved, and the operation is very convenient.

In addition, in the process of the pressure cooking state, the exhaust channel 31 can be opened by driving the heavy ball 32 through the driving device, and periodic exhaust is performed through the exhaust channel 31, so that the air pressure in the cooking cavity 11 is suddenly reduced, and after the air pressure in the cooking cavity 11 is suddenly reduced, the food in the cooking cavity 11 is more vigorously boiled, so that the effect of sudden boiling is formed, and the cooked food is better in afterfeel.

When high-power and high-fire power is used for heating, more steam is generated in the cooking cavity 11, the pressure in the cooking cavity 11 is increased too fast, and the requirement of exhaust cannot be met by exhausting gas close to the exhaust channel 31, which leads to overflow in the cooking process.

In order to solve the problem of overflowing caused by over-pressurization of the cooking cavity 11, in the embodiment, the steam valve 30 has a pressure relief channel 37 for communicating the cooking cavity 11 with the outside, a safety valve 36 is arranged in the pressure relief channel 37, and when the pressure in the cooking cavity 11 is over-pressurized and reaches a threshold value for opening the safety valve 36, the gas in the cooking cavity 11 rushes off the safety valve 36 and is exhausted out of the cooking cavity 11 through the pressure relief channel 37. Through set up pressure release channel 37 on steam valve 30 to set up relief valve 36 on pressure release channel 37, the existence of relief valve 36 only allows the gas in the culinary art chamber 11 to flow out culinary art chamber 11, and outside gas then can not enter into the culinary art chamber 11 by relief valve 36 in, consequently, the negative pressure environment of culinary art chamber 11 can not be influenced in the existence of pressure release channel 37. When the pressure in the cooking cavity 11 is too high, the water vapor is discharged out of the cooking cavity 11 through the safety valve 36 and the pressure relief channel 37, so that the cooking is safer and is not overflowed.

Further, the exhaust passage 31 and the relief passage 37 are not communicated with each other. The exhaust channel 31 and the pressure relief channel 37 are not communicated with each other, so that good sealing performance of the exhaust channel and the pressure relief channel can be ensured, and interaction between the exhaust channel and the pressure relief channel can be prevented.

In addition, in the present embodiment, the steam valve 30 is provided with a limiting cover 33 above the exhaust channel 31, and the limiting cover 33 is used for preventing the heavy ball 32 from completely falling out of the installation position 35. Set up spacing lid 33 above exhaust passage 31, spacing lid 33 can restrict the shift position of heavy ball 32, can prevent in the transportation that heavy ball 32 from deviating from installation position 35 completely, when electromagnetism push rod 21 drive strong magnet 22 kept away from heavy ball 32, can prevent that heavy ball 32 from following strong magnet 22 and deviate from installation position 35.

The utility model discloses compare in ordinary pressure a kind of deep pot, absorb water through the negative pressure and can improve the speed of absorbing water of eating material such as the grain of rice, improve the taste of eating the material, have the pressure culinary art stage, can adjust the pressure of culinary art intracavity at any time, also can exhaust fast and uncap, it is more convenient to use.

Example two

This embodiment is an improvement of the first embodiment, in this embodiment, the push rod 21 of the electromagnetic push rod 21 directly pushes the heavy ball 32 to move, so that the heavy ball 32 leaves the natural state position, and the exhaust passage 31 is opened, so that the outside is communicated with the cooking cavity 11. Compared with the technical scheme of the first embodiment, the driving structure of the embodiment avoids the electromagnetic interference of the strong magnet 22 to the electronic element inside the cover body 20 due to the omission of the strong magnet 22, and simultaneously reduces the manufacturing cost of the electric cooker.

The specific embodiments described herein are merely illustrative of the spirit of the invention.
