Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A cooking appliance and a control method of the cooking appliance according to embodiments of the present invention are described below with reference to the accompanying drawings.
The method for controlling a cooking appliance according to an embodiment of the present invention is based on the cooking appliance according to an embodiment of the present invention, and as shown in fig. 1 and 2, a cooking appliance 100 according to an embodiment of the present invention includes: an air pressure regulator 10.
The air pressure regulator 10 includes an electromagnetic valve 11 and a vacuum pump 12, wherein the electromagnetic valve 11 is used for controlling the on and off of the air exhaust channel, and the vacuum pump 12 is used for exhausting air from the cooking appliance 100 through the air exhaust channel.
Fig. 3 is a flowchart of a control method of a cooking appliance according to an embodiment of the present invention. As shown in fig. 2, the method for controlling a cooking appliance according to an embodiment of the present invention includes the steps of:
s101: acquiring the reserved time length of the cooking appliance.
It should be noted that, a user interaction interface may be provided on the cooking appliance, and is used for receiving the appointment duration input by the user.
S102: and acquiring a vacuum degree preset range corresponding to the cooking utensil in the preset time.
It should be understood that the reserved time length and the vacuum degree have a preset corresponding relationship, that is, when the reserved time length is obtained, a preset range of the vacuum degree corresponding to the reserved time length can be determined by means of table lookup and the like.
S103: within the preset time, according to the preset range of the vacuum degree, the electromagnetic valve or the vacuum pump is controlled to be intermittently opened so as to exhaust the cooking utensil.
That is to say, after the preset duration of the cooking utensil is obtained, the preset range of the vacuum degree corresponding to the cooking utensil is determined according to the preset duration, then the electromagnetic valve or the vacuum pump is controlled to be intermittently started according to the determined preset range of the vacuum degree in the preset duration, the cooking utensil is pumped when the electromagnetic valve or the vacuum pump is started, the vacuum degree in the cooking utensil reaches the preset range of the vacuum degree, and therefore the preset duration of the cooking utensil is effectively prolonged by controlling the vacuum degree in the cooking utensil.
It should be noted that, because in the process of vacuum pumping, the electromagnetic valve is used for controlling the on and off of the pumping channel, and the vacuum pump pumps air from the cooking utensil through the pumping channel, therefore, in the process of pumping air, the electromagnetic valve and the vacuum pump are simultaneously opened, so that the vacuum pump pumps air from the cooking utensil and exhausts the pumped gas through the pumping channel, thereby realizing vacuum pumping, and when the vacuum pump is closed, the electromagnetic valve or the vacuum pump is only needed to be closed to block vacuum pumping. It should be understood that the solenoid valve and the vacuum pump may also be closed at the same time. As a possible embodiment, as shown in fig. 4, step S103 may specifically include S201-S203.
S201: at the initial moment, the electromagnetic valve and the vacuum pump are controlled to be opened.
S202: and detecting the current vacuum degree in the cooking utensil, and controlling the electromagnetic valve or the vacuum pump to be closed if the current vacuum degree is greater than the upper limit value of the preset vacuum degree range.
S203: and continuously detecting the current vacuum degree in the cooking utensil, if the current vacuum degree is continuously detected to be smaller than the lower limit value of the preset vacuum degree range, controlling to restart the electromagnetic valve and the vacuum pump, and returning to execute the subsequent steps until the reservation is finished.
Specifically, when the user selects the reservation function, the electromagnetic valve and the vacuum pump are immediately controlled to be opened so as to vacuumize the cooking appliance. Then detecting the current vacuum degree of the cooking utensil, judging the relation between the current vacuum degree and the upper limit value of the preset range, if the current vacuum degree is larger than the upper limit value of the preset range of the vacuum degree, controlling the electromagnetic valve or the vacuum pump to be closed, if the current vacuum degree is smaller than or equal to the upper limit value of the preset range of the vacuum degree, controlling the electromagnetic valve and the vacuum pump to be opened so as to vacuumize the cooking utensil, so that the vacuum degree of the cooking utensil reaches the maximum value of the preset range of the vacuum degree, and controlling the electromagnetic valve or the vacuum pump to be closed when the vacuum degree reaches the upper limit value of the preset range; and then continuing to detect the current vacuum degree in the cooking utensil, if the detected current vacuum degree is less than or equal to the lower limit value of the preset range of the vacuum degree, controlling to restart the electromagnetic valve and the vacuum pump, if the detected current vacuum degree is greater than the lower limit value of the preset range of the vacuum degree, controlling the electromagnetic valve or the vacuum pump to be in a closed state, and controlling the electromagnetic valve and the vacuum pump to restart until the current vacuum degree is reduced to the lower limit value of the preset range of the vacuum degree. And repeating the steps until the reservation is finished.
That is to say, after the preset time length is obtained, the electromagnetic valve and the vacuum pump are controlled to be opened, a preset vacuum degree range corresponding to the preset time length is obtained, then the current vacuum degree of the cooking utensil is detected in real time, and the vacuum degree of the cooking utensil is continuously between the upper limit value and the lower limit value of the preset vacuum degree range within the preset time length by controlling the opening or closing of the electromagnetic valve and the vacuum pump.
According to one embodiment of the invention, according to the preset range of the vacuum degree, the vacuumizing frequency of the cooking utensil in the preset time length is obtained; wherein the reserved time length is in direct proportion to the vacuumizing frequency; and controlling the electromagnetic valve or the vacuum pump to be intermittently started according to the vacuumizing frequency.
That is to say, in the embodiment of the present invention, the vacuum degree preset range determines the frequency of vacuum pumping, that is, when the corresponding vacuum degree preset range is determined according to the reserved time length, the opening times of the control electromagnetic valve and the vacuum pump can also be determined, and the electromagnetic valve and the vacuum pump are controlled to be opened and closed according to the opening times within the preset time length.
For example, as shown in fig. 5, when the predetermined vacuum range is | P1| - | P11|, the frequency of controlling to open the solenoid valve and the vacuum pump is higher than that when the predetermined vacuum range is | P2| - | P12|, and when the predetermined vacuum range is | P2| - | P12|, the frequency of controlling to open the solenoid valve and the vacuum pump is higher than that when the predetermined vacuum range is | P3| - | P13 |.
As a possible embodiment, before step S102, as shown in fig. 6, S301-S303 are further included.
S301: and judging whether to open the electromagnetic valve and the vacuum pump in the cooking appliance according to the reserved time length.
S302: and if the reserved time length is greater than or equal to the first preset time length, judging that the electromagnetic valve and the vacuum pump need to be opened.
S303: and if the reserved time length is less than the first preset time length, judging that the electromagnetic valve and the vacuum pump do not need to be opened, and controlling the electromagnetic valve and the vacuum pump to be closed.
That is, a first preset time period may be set, and when the preset time period is less than the first preset time period, the cooking appliance does not need to turn on the electromagnetic valve and the vacuum pump, that is, when the preset time period is less than the first preset time period, the preset time period may not need to be extended by a vacuum pumping manner.
Specifically, acquiring an appointment time length, judging whether the appointment time length is greater than or equal to a first preset time length, if the appointment time length is greater than or equal to the first preset time length, judging that an electromagnetic valve and a vacuum pump need to be started, further acquiring a vacuum degree preset range corresponding to the appointment time length, and controlling the electromagnetic valve and the vacuum pump to be started; if the reserved time length is less than the first preset time length, the electromagnetic valve and the vacuum pump can be controlled to be closed or in a closed state without opening the electromagnetic valve and the vacuum pump.
In the embodiment of the present invention, the first preset time period may be 3 hours to 8 hours, and specifically, the first preset time period may be determined according to the cooking food material.
It should be understood that, in the embodiment of the present invention, since the reserved time period is less than the first preset time period, that is, the reserved time period is short, the vacuumizing operation is not required at all, and therefore, the solenoid valve and the vacuum pump need to be controlled to be turned off to save energy.
According to one embodiment of the invention, the reserved time lengths are respectively compared with at least one reserved time length range, a target reserved time length range in which the reserved time lengths are located is determined, and a preset vacuum degree range is obtained according to the target reserved time length range.
That is to say, a plurality of preset duration ranges can be preset, after the preset duration is obtained, the preset duration is respectively compared with at least one preset duration range, when the preset duration is greater than the minimum value of one preset duration range and less than the maximum value of the preset duration range, it is determined that the preset duration is in the preset duration range, that is, the preset duration range is the target preset duration range, and then the preset vacuum degree range is obtained according to the target preset duration range.
Specifically, for example, 3 preset time periods t1, t2 and t3 are preset, wherein t1 is greater than t2 and is greater than t3, when the preset time period t is obtained, whether the preset time period t is greater than a minimum value t1 of the first preset time period is judged, if the preset time period t is less than a minimum value t1 of the first preset time period range, it is determined that the preset time period does not need to be started, if the preset time period t is greater than or equal to a minimum value t1 of the first preset time period range, it is further judged whether the preset time period t is greater than a maximum value t2 of the first preset time period range, if the preset time period t is less than or equal to a maximum value t2 of the first preset time period range, it is determined that the preset time period t is in the first preset time period range, if the preset time period t is greater than a maximum value t2 of the first preset time period range, it is further judged whether the preset time period t is less than or equal to a maximum value t3 of the second preset time period range, and if the preset time length t is less than or equal to the maximum value t3 of the second preset time length range, determining that the preset time length t is in the second preset time length range, and if the preset time length t is greater than the maximum value t3 of the second preset time length range, determining that the preset time length t is in the third preset time length range.
According to an embodiment of the present invention, as shown in fig. 7, the method further includes:
s401: timing the reserved time length, and if the reserved time length is reached, acquiring the current states of the electromagnetic valve and the vacuum pump.
S402: and if the current states of the electromagnetic valve and the vacuum pump are both in an opening state, controlling to close the electromagnetic valve and/or the vacuum pump and entering the next cooking stage.
S403: and if the current state of the electromagnetic valve and/or the vacuum pump is in a closing state, controlling the electromagnetic valve and/or the vacuum pump to be continuously closed and entering the next cooking stage.
That is, the reserved time is timed within the preset time length, when the timed time length reaches the reserved time length, if the current states of the electromagnetic valve and the vacuum pump are in the opening state, the electromagnetic valve and the vacuum pump are controlled to be closed, and the next cooking stage is started, and if the current states of the electromagnetic valve and the vacuum pump are in the closing state, the electromagnetic valve and the vacuum pump are continuously controlled to be closed, and the next cooking stage is started. In other words, when the timing duration reaches the preset duration, the solenoid valve and the vacuum pump need to be controlled to be in a closed state, and then the next cooking stage is started.
