The patent structure of the utility model

The utility model is divided into six parts; a pot shell, an electric kettle, an electric cooker, a pressure cooker, an electric food steamer and a circuit.

The cooker shell comprises a power supply base A, a heat-insulating barrel D and a heat-insulating cover F, the cooker shell has two functions of electric heating and heat insulation, and the heat-insulating barrel D and the heat-insulating cover F form a tight and air-tight space to isolate the inside from the outside, so that the temperature inside is relatively constant.

The power supply base A is responsible for providing 220V commercial power for the heat preservation barrel D. The 'heat-preserving barrel D' is internally designed with a 'constant-temperature knob B', 'electric heating disc C', 'temperature-limiting magnetic steel H', 'steam pipeline G', 'heating switch I', 'steam induction controller V', 'lever switch W' and corresponding electronic circuits. The closing of the power supply switch under different use function requirements is realized through a steam induction controller V, a lever switch W and a constant temperature knob B, and a heat preservation cover F is provided with a vent hole E with a plug.

The "heating switch I" is a mechanical structure that mechanically drives the "steam sensing controller V" and the "lever switch W". When the heating switch I is pressed, the steam induction controller V and the lever switch W can be simultaneously turned on, so that the loop of the electric heating plate C is electrified.

The steam pipeline G is used for triggering a normally closed contact in the steam induction controller V to be switched to a normally open state through the steam pipeline G when the steam pipeline G is used in the working state of the electric kettle, and the heating switch I can be pushed to jump back to the original state while the loop of the electric heating plate C is cut off.

The temperature limiting magnetic steel H is used in the working state of the electric cooker, after the rice is cooked, the permanent magnetic ring in the temperature limiting magnetic steel H loses magnetism and is pressed down by the spring, so that the lever switch W is closed, and the heating switch I is pushed to jump back to the original state while the loop of the electric heating disc C is cut off.

The constant temperature knob B can be provided with a plurality of temperature contact designs to meet different requirements. Once a temperature contact is selected, the temperature within the pot shell can stabilize around the temperature of the contact. The upper part is also designed to be in an off position, is not connected with any electronic circuit and is only a neutral position.

The electric kettle comprises a heat-conducting metal bottom plate J, a heat-insulating inner container K and a kettle cover M, wherein the kettle cover M is provided with a handle S and a kettle nozzle P, the kettle cover M and the heat-insulating inner container K are coupled through a screw, and the electric kettle can be placed into or taken out of a kettle shell through the handle S. The heat-conducting metal bottom plate J is higher than the temperature-limiting magnetic steel H in the cooker shell, so that a permanent magnetic ring in the temperature-limiting magnetic steel H cannot be adsorbed below the heat-conducting metal bottom plate J, and the lever switch W fails. The upper ends of the steam pipeline G in the kettle mouth P and the kettle shell are the same in height, and the electric kettle is butted with the kettle mouth P and the steam pipeline G when being placed into the kettle shell, so that the steam in the electric kettle can be switched to be normally open by triggering the normally closed contact in the steam induction controller V through the steam pipeline G, and a power supply loop of the electric heating plate C is turned off.

The electric cooker comprises a heat-conducting metal bottom plate J, a heat-insulating inner container K and a cooker cover N, wherein a handle S and an air outlet Q are designed on the cooker cover N. The cooker cover N and the heat insulation inner container K are coupled through a screw, and the electric cooker can be put into or taken out of the cooker shell by the handle S. The height of the heat-conducting metal bottom plate J is as high as that of the temperature-limiting magnetic steel H in the cooker shell, so that a permanent magnetic ring in the temperature-limiting magnetic steel H can be adsorbed below the heat-conducting metal bottom plate J, and when the temperature reaches 103 ℃, the permanent magnetic ring in the temperature-limiting magnetic steel H loses magnetism and is pushed down by a spring, so that a bimetallic strip in the lever switch W is disengaged to turn off a power supply loop of the electric heating disc C.

The pressure cooker comprises a heat-conducting metal bottom plate J, a steel cooker L and a cooker cover O, wherein the cooker cover O is provided with a handle S and a pressure valve R. The cooker cover O and the steel cooker L are coupled through a screw, and the pressure cooker can be put into or taken out of the cooker shell by the handle S. The heat-conducting metal bottom plate J is higher than the temperature-limiting magnetic steel H in the cooker shell, so that a permanent magnetic ring in the temperature-limiting magnetic steel H cannot be adsorbed below the heat-conducting metal bottom plate J, and the lever switch W fails. The pressure cooker is not provided with a 'kettle nozzle P' which is butted with a 'steam pipeline G' in the cooker shell, and the 'steam induction controller V' fails in the same way. Therefore, the loop power supply of the electric heating plate C in the working state of the pressure cooker needs to be switched on and off by manually shifting the heating switch I.

The electric food steamer consists of a heat-conducting metal bottom plate J, a food steamer layer U and a food steamer cover X, wherein a handle S and an air outlet T are designed on the food steamer cover X. The side wall of the U-shaped steamer layer on the upper surface is insulated, and the bottom plate is transparent; the bottommost 'food steamer layer U' is directly bottomed by the 'heat-conducting metal bottom plate J', and can contain water. When the water in the lowermost steamer layer U is boiled, the water vapor can reach the upper layer of the permeable bottom plate layer by layer. The height of the heat-conducting metal bottom plate J is as high as that of the temperature-limiting magnetic steel H in the cooker shell, so that a permanent magnetic ring in the temperature-limiting magnetic steel H can be adsorbed below the heat-conducting metal bottom plate J, and when the temperature reaches 103 ℃, the permanent magnetic ring in the temperature-limiting magnetic steel H loses magnetism and is pushed down by a spring, so that a bimetallic strip in the lever switch W is disengaged to turn off a power supply loop of the electric heating disc C.

The multifunctional kitchen electrical appliance circuit mainly comprises three circuits, namely an electric heating loop, a display branch circuit and a control branch circuit.

The electric heating loop mainly comprises a 220V power supply, a fuse FU, a current-limiting resistor R3, a control branch and a heating plate C.

The control branch is divided into three branches, namely a steam induction controller V, a lever switch W and a constant temperature knob B, which are respectively correspondingly applied to the control of the electric kettle, the electric cooker and the heat preservation.

The steam sensing controller V is used for controlling the water temperature in the kettle in the working state of the electric kettle, and a bimetallic strip sensitive to the temperature is arranged in the steam sensing controller V. When the heating switch I is just pressed, the temperature in the steam induction controller V is low, the bimetallic strip is in a closed state, the electric heating loop is electrified, and the temperature of water in the kettle is continuously increased until the water is boiled along with the continuous heating of the electric heating disc C. The boiling water vapor is led into the steam pipeline G through the kettle nozzle P and directly reaches the steam induction controller V, so that the bimetallic strip in the steam pipeline G is deformed and bent to be disconnected, and the loop of the electric heating disc C is powered off.

The lever switch W is used for controlling the temperature in the cooker in the working state of the electric cooker, the permanent magnetic ring and the spring are arranged in the constant-temperature magnetic steel H which is positioned in the center of the heating disc C, the heating switch I is pressed when cooking, the permanent magnetic ring in the constant-temperature magnetic steel H rises and is adsorbed under the heat-conducting metal bottom plate J of the electric cooker by the suction force of the permanent magnetic ring, and therefore the lever switch W is driven to be switched from the normal open state to the normal closed state, and the electric heating disc C is switched on. When the electric heating disc C is continuously heated until the water in the electric cooker is completely burnt to be about 103 ℃, the permanent magnetic ring loses magnetism and is pressed down by the spring, so that the lever switch W is driven to be switched from normal close to normal open, and the loop of the electric heating disc C is switched off to stop heating.

The constant temperature knob B is connected with a plurality of contact switches (30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees and off) with different temperatures in a downward connection mode, and each contact switch is composed of a spring piece, a pair of normally closed contacts, a pair of normally open contacts and a bimetallic strip. When the temperature in the cooker shell is lower than the preset contact temperature, the contacts are in a normally closed state, the electric heating plate C starts to heat, and the temperature in the cooker shell rises. When the temperature in the cooker shell is higher than the temperature of the contacts, the contacts are switched to a normally open state due to the fact that the bimetallic strips are bent due to different thermal shrinkage cases of the bimetallic strips, an electric heating loop is cut off, and heating is stopped. The contacts are repeatedly switched on and off at the contact temperature in such a way, so that the pot shell is always kept at the contact temperature, and the heat preservation effect is achieved.

The display branches show "keep warm" and "heat", the red light L1 "shows" heat ", and the yellow light L2" shows "keep warm". When the heating switch I is pressed, the steam induction controller V is closed under the working state of the electric kettle (the lever switch W is closed under the working state of the electric cooker), the yellow lamp L2 is short-circuited and is not lightened, the red lamp L1 and the R1 are connected in series and then are connected in parallel with the electric heating disc C, the parallel voltage is applied to the red lamp L1 to lighten, and the heating disc C is displayed to be in a heating state. When the temperature is heated to a certain temperature (the electric kettle reaches 100 degrees, and the electric cooker reaches 103 degrees), the steam induction controller V is turned off (or the lever switch W is turned off), the temperature in the cooker shell is higher than the preset contact temperature of the constant temperature knob B, and then the constant temperature knob B is in a disconnected state. Because the resistance value of the electric heating disc C is far smaller than that of the R1, the branch of the red light L1 is short-circuited, the red light L1 is not lighted, the branch of the yellow light L2, the electric heating disc C, the current-limiting resistor R3 and the fuse FU form an unclosed loop, 220V voltage is applied to the yellow light L2 to light up, and the cooker shell is displayed to be in a heat preservation state. If the temperature in the cooker shell is lower than the contact temperature preset by the constant temperature knob B, the constant temperature knob B is in a closed state. The branch of the 'yellow lamp L2' is short-circuited and is not lightened, and the voltage at the two ends of the 'heating plate C' is applied to the 'red lamp L1' to light up, so that the cooker shell is in a 'heating' state.

The specific implementation mode is as follows:

working principle of electric kettle

The electric kettle is placed in the kettle shell, the kettle mouth P is connected with the upper port of the steam pipeline G, and then the heat preservation cover F is covered. The design of the heat-conducting metal bottom plate J of the electric kettle is higher than that of the constant-temperature magnetic steel H, when a heating switch I on the kettle shell is pressed, a permanent magnetic ring in the constant-temperature magnetic steel H cannot be adsorbed below the heat-conducting metal bottom plate J, a lever switch W cannot be closed, and meanwhile, a steam induction controller V is switched on. The fuse FU, the steam induction controller V, the electric heating disc C and the current-limiting resistor R3' form a closed loop, the electric heating disc C heats the electric kettle until water in the kettle boils, boiled water vapor is led into the steam pipeline G through the kettle nozzle P and directly reaches the steam induction controller V, the bimetallic strip in the electric kettle is deformed and bent to be in a normally open state, the loop of the electric heating disc C is cut off, and the water boiling procedure is finished.

Then the cooker shell enters a heat preservation state, and the electric heating disc C is opened and closed according to the preset contact temperature of the constant temperature knob B in a circulating and reciprocating mode so as to keep the contact temperature.

Second, the working principle of electric rice cooker

The electric cooker is arranged in the cooker shell, the air outlet Q of the electric cooker is approximately aligned with the air outlet E with the plug of the cooker shell, and then the heat preservation cover F is covered. The height of the heat-conducting metal bottom plate J of the electric cooker is designed to be as high as that of the constant-temperature magnetic steel H, and the weight of the electric cooker can reduce the constant-temperature magnetic steel H to be as high as that of the electric heating disc C. When a heating switch I of the multifunctional kitchen appliance is pressed down, a permanent magnetic ring in the constant-temperature magnetic steel H is adsorbed below a heat-conducting metal bottom plate J, and a lever switch W is closed. The fuse FU, the lever switch W, the electric heating disc C and the current-limiting resistor R3' form a closed loop, the electric heating disc C heats the electric cooker until the water in the cooker is dried and continuously rises to about 103 degrees, the permanent magnetic ring in the constant-temperature magnetic steel H loses magnetism and is pressed by the spring to turn off the lever switch W, the heating loop is cut off, and the heating disc C stops heating.

When the heating switch I is pressed down, the lever switch W is closed, and the steam induction controller V is also closed, but the steam induction controller V does not work because the electric cooker does not have the kettle mouth P on the electric kettle and the steam pipeline G which are communicated. When the constant temperature magnetic steel H loses magnetism and is pressed down by the spring, the mechanical structure in the heating switch I rebounds the heating switch I to the original state, and the bimetallic strip in the steam induction controller V returns to the normally open state again.

Pressure cooker

The pressure cooker is arranged in the cooker shell, a pressure valve R of the pressure cooker is approximately aligned with an air outlet hole E with a plug of the cooker shell, and then a heat preservation cover F is covered. The design of the heat-conducting metal bottom plate J of the pressure cooker is higher than the constant-temperature magnetic steel H of the cooker shell, when the heating switch I of the cooker shell is pressed, a permanent magnetic ring in the constant-temperature magnetic steel H cannot be adsorbed below the heat-conducting metal bottom plate J, the lever switch W cannot be closed, and the steam induction controller V is switched on at the same time. The fuse FU, the steam induction controller V, the electric heating plate C and the current limiting resistor R3' form a closed loop, and the electric heating plate C continuously heats the pressure cooker until the pressure cooker is boiled. Meanwhile, the pressure cooker does not have a spout P for guiding water vapor to switch the contact of the steam induction controller V like an electric kettle, so that the heating switch I needs to be manually turned to switch the contact of the steam induction controller V through a mechanical structure, and a heating loop is turned off.

Then the pressure cooker enters a heat preservation state, and the heating plate C is opened and closed according to the preset contact temperature of the constant temperature knob B in a circulating and reciprocating mode so as to keep the contact temperature.

Four, electric food steamer

The electric food steamer is placed in the cooker shell, a proper amount of water is added into the food steamer layer U at the bottommost layer, food needing to be steamed is placed into the food steamer layer U at the upper layer, the air outlet holes T on the food steamer cover are approximately aligned to the air outlet holes E with the plugs of the cooker shell, and then the heat preservation cover F is covered. The height of the heat-conducting metal bottom plate J of the electric food steamer is designed to be as high as the constant-temperature magnetic steel H, and the constant-temperature magnetic steel H can be pressed down to be as high as the electric heating disc C by the weight of the electric food steamer. When a heating switch I of the multifunctional kitchen appliance is pressed down, a permanent magnetic ring in the constant-temperature magnetic steel H is adsorbed below a heat-conducting metal bottom plate J, and a lever switch W is closed. The fuse FU, the lever switch W, the electric heating disc C and the current-limiting resistor R3' form a closed loop, the electric heating disc C heats the electric steamer until water in the steamer is dried and continuously rises to about 103 degrees, a permanent magnetic ring in the constant-temperature magnetic steel H loses magnetism and is pressed by a spring to turn off the lever switch W, the heating loop is cut off, and the electric heating disc C stops heating.

After the heating switch I is pressed, the lever switch W is closed, and the steam induction controller V is also closed, but the steam induction controller V does not work because the electric steamer is not communicated with the steam pipeline G and the kettle mouth P on the electric kettle. When the permanent magnetic ring in the constant temperature magnetic steel H loses magnetism and is pressed down by the spring, the mechanical structure in the heating switch I rebounds the heating switch I, and the bimetallic strip in the steam induction controller V returns to a normally open state again.

Then the electric food steamer enters a heat preservation state, and the heating plate C is opened and closed according to the preset contact temperature of the constant temperature knob B in a circulating and reciprocating mode so as to keep the contact temperature.

Fifth, the drying and heat preservation working principle of the cooker shell

The utility model has the functions of heat preservation and drying besides the four functions;

the food to be insulated is put into the food steamer layer U in layers, the insulation cover F is covered, the vent hole E with the plug is plugged, and the constant temperature knob B is opened to the required temperature.

And (3) placing the vegetables and fruits to be dried into the steamer layer U in a layered manner, opening the heat-preservation cover F, and opening the constant-temperature knob B to a proper temperature. Because the heat preservation cover F is opened, the electric heating plate C is repeatedly opened and closed near the contact temperature of the constant temperature knob B, and the moisture in the fruits and vegetables is volatilized at any time through the opened heat preservation cover F, so that the drying effect is achieved.
