Problems solved by technology

However, using this method requires the user to have a certain knowledge of the heat preservation of the electric rice cooker. If the temperature adjusted by the user cannot compensate for the heat loss in the pot, the rice will easily deteriorate; if the temperature adjusted by the user is too high, there will be a disadvantage of power consumption.
Moreover, the user operation is relatively cumbersome and not humanized

Embodiment 1

[0032] The electric rice cooker includes a central controller, an opening and closing lid detection device, an electric heater and a pot body temperature detector electrically connected to the central controller. The lid opening and closing detection device is a detection device used to detect the opening and closing of the lid, and transmits the two action processes of opening and closing the lid to the central controller through electrical signals. The pot body temperature detector is a detection device used to detect the pot body temperature, and can transmit the detected temperature to the central controller through electrical signals. The central controller is a complete set of circuits including a timer for processing various electric signals of the electric cooker and controlling the working process of the electric cooker. The mode automatically detects, processes and controls the temperature, working time and working mode of the rice cooker, and displays the processing...

Embodiment 2

[0036] On the basis of Example 1, as figure 2 As shown, the method of the present invention also includes the following control steps:

[0037] Step 1: When the rice cooker enters the energy-saving and heat-insulating state, the central controller detects whether the lid has an opening action (S101), and if not, the central controller maintains the energy-saving and heat-preserving state until 12 hours after the rice cooking ends. Control the electric cooker to enter the standby state (S106), if yes, enter step 2.

[0038] Step 2: The central controller controls the electric cooker to enter a normal heat preservation state after picking up the lid opening signal (S102) to compensate for the heat loss in the pot.

[0039] Step 3: After the electric cooker enters the normal heat preservation state, the central controller detects whether the lid is closed within the set time (S103), if not, the central controller controls the electric cooker to directly enter the standby state ...

Embodiment 3

[0042] On the basis of Example 1, as image 3 As shown, the method of the present invention also includes the following control steps:

[0043] Step A: Within 1 hour after the electric cooker enters the energy-saving and heat-preserving state, the central controller detects whether there is an opening action on the lid (S201), and if so, the central controller picks up the lid-opening signal after picking up the signal. The electric cooker is controlled to enter a normal heat preservation state (S202), and the heat loss in the pot is started to be compensated.

[0044] Step B: After the electric cooker enters the normal heat preservation state, the central controller detects whether the lid is closed within the set time (S203), if not, the central controller controls the electric cooker to directly enter the standby state (S208 ), if yes, go to step C.

[0045] Step C: The central controller starts to control the electric cooker to enter the energy-saving and heat-preserving...

Abstract

The invention discloses a heat preservation method of an electric rice cooker comprising a central controller, a cover opening and closing detection device connected with the electrical signal of the central controller, an electric heater and a cooker body temperature detector, wherein the cover opening and closing detection device transfers picked up cover opening and closing signals to the central controller; the cooker body temperature detector transfers picked up cooker body temperature signals to the central controller; the central controller controls the heating temperature of the electric rice cooker by controlling the electric heater; when the environmental temperature is 18-28 DEG C and the rice cooking process is ended, the central controller controls the electric rice cooker to enter an energy-saving heat preservation state; moreover, after the rice cooking is finished by 12 hours, the central controller controls the electric rice cooker to enter a standby state. The electric rice cooker using the heat preservation method has convenient operation, saves electricity and can preserve the heat of rice in the electric rice cooker for a long time without going bad. The invention can be suitable for various electric rice cookers.

Description

technical field [0001] The invention relates to the field of electric rice cookers, in particular to a heat preservation method for an electric rice cooker. Background technique [0002] In daily life, most rice cookers currently use the normal heat preservation mode that directly enters a higher temperature after cooking. This heat preservation mode is relatively power-intensive, and this single heat preservation mode cannot adjust the heat preservation method according to the specific situation. Always in a state of high power consumption. Some people have proposed a rice cooker heat preservation control method by setting the heat preservation temperature on the control panel, such as the patent application No. 97112114.1, the Chinese patent application entitled "The heat preservation control method of the rice cooker", which discloses a kind of heat preservation control method for electric cooker. In the heat preservation control method of the rice cooker, the heat prese...
