Description

Electric heating appliances with cover opening detection mechanism

technical field

The utility model relates to an electric heating appliance, such as an electric rice cooker or an electric pressure cooker.

Background technique

Chinese patent CN 203369774U discloses an electric rice cooker on 2014-01-01, comprising: a cooker body; a cooker cover, which is used to cover the cooker body to define a cooking cavity with the cooker body; mechanism, the cover-opening mechanism is installed on the pot body and is connected with the pot cover to open or close the pot cover; and a foam detector for detecting the foam in the cooking cavity, the cover-opening mechanism is connected with the foam detector for Open the lid when the foam detector detects foam.

At present, most electric heating appliances (such as electric rice cookers or electric pressure cookers) on the market do not have cover opening detection. When the electric heating appliance is in the open state, if the user accidentally touches the operation button, the electric heating appliance may be turned on and in the heating state. Therefore, there may be safety hazards.

Utility model content

In view of the above-mentioned shortcomings of the prior art, according to the embodiment of the present invention, it is hoped to provide an electric heating appliance that can detect whether the lid is opened or closed, and then control whether the heating work should be performed, so as to prevent the user from In the state of opening the cover, if you accidentally touch the operation button, it will cause the boot to work, eliminating potential safety hazards.

According to the embodiment, the utility model provides an electric heating appliance with a cover opening detection mechanism, which includes a pot cover, and its innovative point is that it further includes a cover opening detection mechanism, which includes an anti-fall switch and a processor unit , the anti-fall switch is installed in the lid, the processor unit is a controller with MCU, the anti-fall switch is electrically connected to the controller with MCU, and the MCU judges that the lid is open by detecting the open or closed state of the anti-fall switch status or closed status.

According to one embodiment, in the aforementioned electric heating appliance with a lid opening detection mechanism of the present invention, the anti-fall switch is integrated in the processor unit.

According to one embodiment, in the aforementioned electric heating appliance with a lid opening detection mechanism of the present invention, when the lid is closed, the anti-fall switch is in the closed state; when the lid is opened, the anti-fall switch is in the off state.

According to one embodiment, in the aforementioned electric heating appliance with a lid opening detection mechanism of the present invention, when the lid is closed, the anti-fall switch is in the off state; when the lid is opened, the anti-fall switch is in the closed state.

The working principle of the utility model is that when the user closes the lid, the lid is in a horizontal state, and the anti-fall switch is in a closed state (or disconnected, set by the processor unit), when the lid is opened, the lid and the After the level is at a certain angle, the anti-fall switch is in the off state (or closed state, set by the processor unit), and the processor unit detects the different states of the anti-fall switch to know whether the lid is in the open state or closed state State, and then can be controlled: when the cover is closed, the rice cooker is allowed to perform button operations, heating, etc.; when the cover is opened, the rice cooker is not allowed to perform button operations, heating, etc.

Compared with the prior art, the utility model uses the different switch characteristics when the anti-fall switch is in the horizontal state and the vertical state to detect whether the lid is in the open state or the closed state, and detects the state of the anti-fall switch through the controller with MCU. Switching characteristics, control the heating work of the rice cooker when the cover is closed, and not heating work when the cover is opened, so as to avoid the heating work when the rice cooker is opened due to misoperation, and prevent potential safety hazards.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, further set forth the utility model. These embodiments should be understood as only for illustrating the utility model but not for limiting the protection scope of the utility model. After reading the contents of the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent changes and modifications also fall within the scope defined by the claims of the utility model.

In the following embodiments of the present invention, although the rice cooker is taken as an example, those skilled in the art can apply the technical solution of the present invention to electric kitchen utensils or living room appliances, such as electric pressure cookers, according to the following embodiments.

As shown in Figure 1, a preferred embodiment of the utility model provides an electric rice cooker with a detection opening and closing cover device, including a cooking panel 1, an anti-fall switch 2, a connecting wire 3, a processing unit 4 of a controller with an MCU, and a cooker. Cover 5, rice cooker body 6 and cover opening button 7. The connection and cooperation between the cooking panel 1, the pot cover 5, the rice cooker body 6 and the cover opening button 7 can be done according to conventional means in the art.

The anti-fall switch 2 is arranged and integrated on the processing unit 4 (also as shown in Figure 2, the anti-fall switch 2 and the processing unit 4 are electrically connected by the connecting wire 3), and the processing unit 4 is installed in the pot cover 5, so that the anti-fall The state of the switch 2 changes with the opening and closing of the lid 5 .

When the user closes the pot cover 5, the pot cover 5 is in a horizontal state, and the anti-fall switch 2 is in a closed state (or disconnected state, set by the processor unit), and when the pot cover 5 is opened, the pot cover 5 is in a certain level After the included angle, the anti-fall switch 2 is in the off state (or closed state, set by the processor unit), and the MCU of the processor unit 4 judges whether the pot lid 5 is in the open state by detecting the different states of the anti-fall switch 2 It is still in the closed state, and then can be controlled: when it is in the closed state, the rice cooker is allowed to perform key operations, heating, etc.; when it is in the open state, the electric rice cooker is not allowed to perform key operations, heating, etc.
