Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring embodiments of the present invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, however, other embodiments of the invention are possible in addition to these detailed descriptions.

A cooking appliance according to a preferred embodiment of the present invention will be described below with reference to fig. 1 to 2. It can be understood, according to the utility model discloses a cooking utensil can be for electric rice cooker, electric pressure cooker or other cooking utensil, and according to the utility model discloses a cooking utensil except having the function of cooking rice, can also have various functions such as cooking congee. For the sake of brevity, the overall schematic of the cooking appliance is not shown.

Generally, a cooking appliance includes a lid and a pot body. The pot body is substantially in a rounded rectangular parallelepiped shape and has an inner pot receiving portion in a cylindrical shape, and the lid body may have substantially the same shape as the pot body and serve to cover the pot body. The inner pot can be freely put into the inner pot containing part or taken out of the inner pot containing part, so that the inner pot is convenient to clean. The upper surface of the inner pot has a circular opening for containing materials to be heated, such as rice, soup, etc., into the inner pot. The cooker body includes therein a heating module 130 for heating the inner pot.

As shown in fig. 1, the cooking appliance further includes a control module 110, and a human proximity sensing module 140 and a voice recognition module 120 electrically connected to the control module 110.

The human proximity sensing module 140 is configured to detect the presence of a human body within a predetermined area and to generate a sensing signal when the presence of a human is detected. Illustratively, the human proximity sensing module 140 may be an infrared sensor. When a person enters the sensing area, the infrared sensor detects the change of the infrared spectrum of the human body, the load is automatically switched on, so that a sensing signal is generated, and the load is automatically switched off after the person leaves. Of course, the human proximity sensing module 140 may also be configured as other sensing devices, such as an ultrasonic sensor.

Preferably, the preset area is an area within 0.2-5 m away from the human body to approach the induction module. That is, the predetermined region set in the cooking appliance of the present embodiment is a sensing distance within 0.2 to 5m from the human body approaching sensing module 140. Wherein, 0.2 ~ 1m is more preferred induction distance, and the user of judgement that can be more accurate is the cooking utensil of intentionally being close to, probably operates cooking utensil. However, the sensing distance is not limited thereto, and may be adjusted according to specific needs in other embodiments. For example, the specific value of the range may be changed according to the sensitivity of the human proximity sensing module 140.

The voice recognition module 120 can receive and recognize a voice command issued by a user. The preferred embodiment enables the user to input cooking information directly in a voice mode, and operation of the user is facilitated. For example, the user may issue a voice instruction such as "start cooking" or "pause cooking".

The control module 110 wakes up the voice recognition module 120 in response to receiving the sensing signal from the human proximity sensing module 140. The voice recognition module 120 sends a voice command to the control module 110, and the control module 110 performs corresponding control on the cooking appliance in response to the received voice command.

In order to avoid the voice recognition module continuously responding to various instructions to affect the normal cooking procedure when the cooking appliance is in the cooking state, preferably, the control module 110 is configured to enable the voice recognition module 120 not to be awakened even if the induction signal sent by the human body proximity induction module 140 is received when the cooking appliance is in the cooking state, and the voice recognition module cannot send the voice instruction to ensure that the cooking is normally operated. Therefore, when the cooking appliance is in a cooking state, the voice recognition function of the cooking appliance cannot be triggered even if a person approaches the cooking appliance, so that misoperation can be avoided. It will be understood that reference herein to "cooking state" is to a state in which the cooking appliance has entered a cooking program and the heating module has started to operate.

It is further preferred that the voice recognition module 120 is configured to be awakenable only by a specific wake-up word when the cooking appliance is in the cooking state. This scheme can guarantee that the speech recognition module can only be awaken by the people who really intends to operate cooking utensil under cooking utensil is in the culinary art state to can avoid the maloperation. The specific wake-up word may be, for example, "wake up", or the like, and may be stored in the cooking appliance when the cooking appliance leaves the factory, or may be set by the user.

The voice recognition module 120 can recognize only a predetermined voice command when it is awakened in the cooking state. The predetermined voice command is a voice command to cancel cooking. According to the scheme, on one hand, the interference to a normal cooking program can be avoided, and on the other hand, a user can conveniently cancel the cooking operation in time when the user does not want to continue cooking or change cooked food.

The working principle of the cooking appliance according to the present invention is described in detail below with reference to fig. 2.

In the default state, the speech recognition module 120 is in the sleep state. When the human body proximity sensing module 140 detects that a user approaches, a sensing signal is generated and transmitted to the control module 110. The control module 110 detects whether the cooking appliance is in a non-cooking state after receiving the sensing signal, and wakes up the voice recognition module 120 when determining that the cooking appliance is in the non-cooking state. At this time, the user may issue a voice command (e.g., start cooking), and the voice recognition module 120 receives and recognizes the voice command issued by the user and transmits the recognized voice command to the control module 110. The control module 110 automatically performs various controls on the cooking appliance when receiving the recognized voice command. And the voice recognition module 120 is not awakened when the control module 110 detects that the cooking appliance is in the cooking state. At this time, the speech recognition module 120 can only be woken up by a specific wake word, which has been described above for this scheme and is not described herein again for brevity.

According to the utility model discloses a cooking utensil can be when being in under the non-culinary art state detecting the human body and arouse the speech recognition module when being close to automatically to the user can directly assign the speech control instruction and control cooking utensil, thereby has improved the convenience and the security of operation.
