Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, a cooking appliance 100 according to an embodiment of the present invention is used for heating food to achieve cooking of the food. Cooking utensil 100 includes pot 20, air intake device 40, and exhaust device (not shown). Wherein, pot body 20 has the chamber 21 that holds that is used for splendid attire and heating food, and air inlet unit 40 is connected with pot body 20 and with hold chamber 21 intercommunication for carry external gas to holding in the chamber 21, and exhaust apparatus is connected with pot body 20 and with holding chamber 21 intercommunication for the gas in pot body 20 is discharged. It should be noted that, since the specific structure of the pot body 20 and the exhaust device is well-known in the art, it is not described herein.
Referring to fig. 1, the air inlet device 40 includes an air inlet unit 41 and a one-way conducting unit 43. Wherein, the air outlet of the air inlet unit 41 is connected with the pan body 20 through a pipeline, the one-way conduction unit 43 is arranged between the air inlet unit 41 and the pan body 20, the one-way conduction unit 43 allows the outside air to flow into the accommodating cavity 21 of the pan body 20 from the air inlet unit 41 in one way, and the air in the accommodating cavity 21 can not flow out through the one-way conduction unit 43.
In this way, the air intake unit 41 draws air from the external environment and inputs it into the containing cavity 21 of the pot 20 through the one-way conduction unit 43. Due to the one-way conduction unit 43, the air flow can only flow into the accommodating cavity 21 of the pot body 20 from the air inlet unit 41, and cannot reversely pass through the one-way conduction unit 43 from the accommodating cavity 21. Specifically, in some embodiments, the air inlet unit 41 is an air pump, and the one-way conducting unit 43 is a one-way valve or a solenoid valve controlled switch.
In some embodiments, the air intake device 40 further includes an air filtering unit 45, the air filtering unit 45 is disposed between the air intake unit 41 and the one-way conduction unit 43 or connected to the air inlet of the air intake unit 41, and the air filtering unit 45 can filter the air entering the accommodating cavity 21, so as to prevent the impurities in the external environment from entering the accommodating cavity 21 through the air intake device 40.
In some embodiments, the air intake device 40 further includes a silencing unit 47, and the silencing unit 47 is connected to an air inlet of the air intake unit 41 and is used for reducing transmission of noise generated by the air intake unit 41 to the outside.
Further, in order to detect whether the unidirectional conducting unit 43 fails, the cooking appliance 100 further includes a detecting device 60 and a control unit (not shown), wherein the detecting device 60 can detect the operating state of the unidirectional conducting unit 43, and the control unit controls the operating state of the cooking appliance 100 according to the operating state of the unidirectional conducting unit 43.
Specifically, the detection device 60 includes an air suction unit 61, an air inlet of the air suction unit 61 is connected to an air inlet of the one-way conduction unit 43, and the air suction unit 61 is used for sucking the gas on the side of the one-way conduction unit 43. The control unit is used for acquiring the working parameters of the detection device 60 and judging whether the unidirectional conducting unit 43 fails or not according to the working parameters of the detection device 60.
Since the unidirectional flux unit 43 only allows the gas to flow in one direction when the unidirectional flux unit 43 is active, the gas-extracting unit 61 cannot extract the gas in the accommodating cavity 21 of the pot 20, and when the unidirectional flux unit 43 fails, the unidirectional flux unit 43 allows the gas to flow in the opposite direction, and the gas-extracting unit 61 can normally extract the gas in the accommodating cavity 21 of the pot 20, so that the operating parameters of the detecting device 60 when the unidirectional flux unit 43 is active are not consistent with the operating parameters of the detecting device 60 when the unidirectional flux unit 43 fails. Therefore, the control unit can obtain the operating parameters of the detection device 60, determine whether the one-way conduction unit 43 fails according to the operating parameters, and send an alarm to prompt a user when the one-way conduction unit 43 fails, thereby effectively preventing the high-temperature steam in the pot body 20 from reversely flowing to the air inlet unit 41 to damage the air inlet unit 41 due to the operation of the cooking appliance 100 in the state that the one-way conduction unit 43 fails.
As shown in fig. 1, in the first embodiment of the present application, the operating parameter of the detecting device 60 is the operating current value of the pumping unit 61.
When the working current value of the air extracting unit 61 is greater than the preset current value, it indicates that the operation of the air extracting unit 61 is subjected to resistance, the air extracting unit 61 cannot extract the gas in the pot body 20, the motor in the air extracting unit 61 is locked, so that the working current value of the air extracting unit 61 is increased, and the control unit judges that the one-way conducting unit 43 is effective.
When the working current value of the air extracting unit 61 is less than or equal to the preset current value, it indicates that the air extracting unit 61 can normally operate to extract the gas in the pot body 20, and the control unit determines that the one-way conduction unit 43 is failed, and then sends an alarm to remind a user.

When the air pressure between the air extracting unit 61 and the one-way conducting unit 43 is smaller than the preset air pressure, it indicates that negative pressure occurs between the air extracting unit 61 and the one-way conducting unit 43 due to the air between the air extracting unit 61 and the one-way conducting unit 43 being extracted, and the air in the accommodating cavity 21 of the pot body 20 cannot be supplemented to the air extracting unit 61 due to the obstruction of the one-way conducting unit 43, and the control unit determines that the one-way conducting unit 43 is effective.
When the air pressure between the air extracting unit 61 and the one-way conduction unit 43 is equal to or greater than the preset air pressure, it indicates that the one-way conduction unit 43 does not have the blocking function, the air extracting unit 61 can continuously extract the air in the accommodating cavity 21 of the pot body 20, and the control unit determines that the one-way conduction unit 43 is invalid.
As shown in fig. 3, in the third embodiment of the present application, the detecting device 60 further includes a gas flow detecting unit 65, the gas flow detecting unit 65 is disposed between the gas extracting unit 61 and the pot 20, the gas flow detecting unit 65 is used for detecting a gas flow value between the gas extracting unit 61 and the pot 20, and an operating parameter of the detecting device 60 is the gas flow value between the gas extracting unit 61 and the pot 20.
When the gas flow value between the air extraction unit 61 and the pot body 20 is smaller than the preset flow value, almost no gas flows between the air extraction unit 61 and the pot body 20 due to the blocking effect of the one-way conduction unit 43 on the surface, so the control unit judges that the one-way conduction unit 43 is effective.
When the gas flow value between the air extraction unit 61 and the pot body 20 is larger than the preset flow value, the surface one-way conduction unit 43 does not have an effective blocking function, the air extraction unit 61 can continuously extract the gas in the pot body 20, and the air flow continuously flows between the air extraction unit 61 and the pot body 20, so that the control unit judges that the one-way conduction unit 43 fails.
