A weight display method of a cooking apparatus, a weighing device of a cooking apparatus, and a cooking apparatus according to embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a weight display method of a cooking apparatus according to an embodiment of the present invention. A weighing device is arranged on an inner pot of the cooking equipment and comprises a weighing sensor, a display unit and a storage unit, and as shown in figure 1, the weight display method of the cooking equipment comprises the following steps:
s10: and acquiring the current weight value of the object to be measured in the inner pot according to the weighing signal output by the weighing sensor.
According to one embodiment of the invention, the weighing device may be arranged in a handle assembly of the inner pan, which may be fixedly connected with the inner pan by means of a fixing assembly. Specifically, the handle assembly may include a first handle and a second handle, the first handle and the second handle are respectively disposed at both ends of the inner pan, the weighing device may include a weighing sensor, wherein the weighing sensor may include a first weighing sensor and a second weighing sensor, the first weighing sensor and the second weighing sensor may be respectively disposed in the first handle and the second handle, the weighing device further includes a control unit and a display unit, the control unit may be disposed in the first handle and/or the second handle, and the display unit may be disposed on the first handle and/or the second handle.
It should be noted that the weighing device is used for weighing the food materials (such as rice or rice-water mixture) placed in the inner pot, when the handle assembly is lifted upwards from the bottom of the handle assembly by two hands, the force acts on the weighing sensor, the weighing sensor deforms to generate an electric signal, the electric signal is fed back to the control unit as a weighing signal, and the control unit can judge the weight value according to the weighing signal, so that the weighing function is realized, and the display unit is controlled to display corresponding contents according to the weight value.
S20: and judging the state of the weighing device.
Specifically, when the weighing sensor receives an external force, for example, when the handle assembly is lifted up from the bottom of the handle assembly by both hands, it can be judged that the weighing device is in a weighing state; when the weighing sensor does not receive the action of external force, for example, the hands do not contact the handle assembly, the weighing device can be judged not to be in a weighing state.
S30: if the weighing device is in a weighing state, the historical weight value stored in the storage unit and the historical weight value displayed by the display unit are adjusted according to the current weight value of the object to be measured in the inner pot.
S40: and if the weighing device is not in the weighing state, controlling the display unit to display the historical weight value stored in the storage unit.
Particularly, after the weighing device acquires the weight value of the to-be-measured object in the inner pot according to the weighing signal output by the weighing sensor, the weight value of the to-be-measured object is stored in the storage unit, whether the weighing sensor receives the external force action or not is judged, if the weighing sensor receives the external force action, the weighing device is judged to be in a weighing state, and the current weight value of the to-be-measured object in the inner pot is acquired in real time according to the weighing signal output by the weighing sensor. When the obtained current weight value of the object to be measured in the inner pot meets a preset condition, the weight value stored in the storage unit is adjusted to be the current weight value, and the display unit is controlled to display the adjusted weight value; when the obtained current weight value of the object to be measured in the inner pot does not meet the preset condition, the storage unit is controlled to continuously store the historical weight value (namely the original weight value), and the display unit is controlled to display the historical weight value (namely the original weight value). On the contrary, if the weighing sensor does not receive the action of external force, the weighing device is judged not to be in a weighing state, and the display unit is controlled to display the historical weight value (namely the original weight value) stored in the storage unit.
According to an embodiment of the present invention, the adjusting of the historical weight value stored in the storage unit and the historical weight value displayed by the display unit according to the current weight value of the object to be measured in the inner pot comprises: acquiring a fluctuation range corresponding to the historical weight value; judging whether the current weight value of the object to be detected exceeds the fluctuation range; if the current weight value of the object to be measured exceeds the fluctuation range, controlling the storage unit to store the current weight value and controlling the display unit to display the current weight value; and if the current weight value of the object to be measured does not exceed the fluctuation range, controlling the historical weight value stored in the storage unit and displayed by the display unit to be kept unchanged.
Particularly, when weighing device is in the state of weighing, can be according to the historical weight value of the current weight value adjustment memory cell storage of determinand in interior pot and the historical weight value that the display element shows. For example, defining the historical weight value stored in the storage unit as M1, a fluctuation range corresponding to the historical weight value M1 may be obtained from the historical weight value M1 and a preset fluctuation threshold value M, where the difference (M1-M) between the historical weight value M1 and the preset fluctuation threshold value M is taken as the lower limit value of the fluctuation range, and the sum (M1+ M) of the historical weight value M1 and the preset fluctuation threshold value M is taken as the upper limit value of the fluctuation range.
When the user lifts the inner pot again through the handle assembly for weighing, the current weight value of the object to be measured in the inner pot is obtained according to the weighing signal output by the weighing sensor, the current weight value is defined as M2, whether the current weight value M2 exceeds the fluctuation range corresponding to the historical weight value M1 or not is judged, if the current weight value M2 exceeds the fluctuation range corresponding to the historical weight value M1, the storage unit is controlled to store the current weight value M2, and the display unit is controlled to display the current weight value M2; if the current weight value M2 does not exceed the fluctuation range corresponding to the historical weight value M1, the control display unit continues the historical weight value M1.
According to one embodiment of the present invention, the preset fluctuation threshold m may be 0 to 50 g. Wherein, the smaller the preset fluctuation threshold value m is, the higher the weighing precision is. That is, when the preset fluctuation threshold M is 30g, the lower limit value of the fluctuation range of the historical weight value may be (M1-30), and the upper limit value of the fluctuation range of the historical weight value may be (M1+ 30).
According to another embodiment of the present invention, the preset fluctuation threshold M may be a preset ratio η of the historical weight value M1. That is, when the preset fluctuation threshold M is the preset ratio η of the historical weight value M1, that is, M1 η, the lower limit value of the fluctuation range of the historical weight value may be (M1-M1 η), and the upper limit value of the fluctuation range of the historical weight value may be (M1+ M1 η).
According to an embodiment of the present invention, the preset ratio η may be 5% to 10%, and the preset ratio η decreases as the weight-indicated value M1 increases.
According to an embodiment of the present invention, when the storage unit is controlled to store the current weight value and the display unit is controlled to display the current weight value, if the current weight value belongs to the preset zero point range, the display unit is controlled to display 0.
Particularly, when the weighing device of cooking equipment is in the state of weighing, but weighing sensor real-time output weighing signal, the current weight value of determinand in the pot is obtained according to the weighing signal of weighing sensor output to judge whether current weight value belongs to the scope of presetting zero point, if judge that current weight value belongs to the scope of presetting zero point, then explain that current weight value is in near zero point, and be less than the error value that weighing sensor can discern, this moment, control display element shows 0.
According to an embodiment of the present invention, the predetermined zero range may be [ -M, + M ], and M may range from 0g to 100 g. Assuming that M is 100g, the lower limit value of the zero point range is-100 g, and the upper limit value of the zero point range is 100 g. Wherein, the upper limit value + M of zero point scope represents the error value that weighing sensor can discern, that is to say, if the weight detected value is greater than the upper limit value + M of zero point scope, then weighing sensor can accurately discern the weight value of the food material of placing in the inner pot.
It should be noted that the smaller the value of M, the higher the weighing accuracy of the load cell.
According to one embodiment of the invention, the state of the weighing device is judged according to the current weight value of the object to be measured in the inner pot, wherein if the current weight value is smaller than the lower limit value of the preset zero point range, the weighing device is judged not to be in the weighing state; and if the current weight value is larger than or equal to the lower limit value of the preset zero point range, judging that the weighing device is in a weighing state.
Specifically, in a preferred embodiment of the present invention, assuming that M is 100g, the zero range of the weighing apparatus is [ -100g, +100g ]. After a weighing device of the cooking equipment is started, the weighing sensor can output a weighing signal in real time, the current weight value of an object to be measured in the inner pot is obtained according to the weighing signal output by the weighing sensor, whether the current weight value belongs to the range of [ -100g, +100g ] or not is judged, if the current weight value is smaller than the lower limit value of the zero range, for example, -100g, the weighing device is judged not to be in a weighing state, namely, the inner pot 200 is not lifted up through the handle assembly 300, and at the moment, the control display unit displays the historical weight value (namely, the original weight value) stored in the storage unit. If the current weight value is larger than or equal to the lower limit value of the preset zero point range, for example, -100g, the weighing device is judged to be in the weighing state, namely the handle assembly of the inner pot is lifted through the handle, and at the moment, the historical weight value stored in the storage unit and the historical weight value displayed by the display unit are adjusted according to the current weight value of the object to be measured in the inner pot.
When the cooking equipment is in a weighing state, the weighing sensor can output a weighing signal in real time, the current weight value of an object to be measured in the inner pot is obtained according to the weighing signal output by the weighing sensor, if the weight detection value is judged to be larger than the upper limit value + M (for example +100g) of the zero point range, the fact that food materials (for example, rice or a rice-water mixture) are placed in the inner pot of the weighing device is indicated, and the weight value of the placed food materials is higher than an error value which can be identified by the weighing sensor. Further, the historical weight value stored in the storage unit and the historical weight value displayed by the display unit are adjusted according to the current weight value of the object to be measured in the inner pot, if the current weight value of the object to be measured exceeds the fluctuation range, the current weight value is stored in the storage unit, and the display unit is controlled to display the current weight value, wherein the current weight value is the actual weight value of the food material put into the inner pot; and if the current weight value of the object to be measured does not exceed the fluctuation range, controlling the historical weight value stored in the storage unit and displayed by the display unit to be kept unchanged.
According to one embodiment of the present invention, when the weighing apparatus is in a weighing state, if the memory unit does not store the historical weight value, the current weight value is stored in the memory unit, and the display unit is controlled to display the current weight value; when the weighing device is not in the weighing state, if the storage unit does not store the historical weight value, the display unit is controlled to display zero.
Specifically, when the weighing device is started and weighing is carried out for the first time, the storage unit does not usually store a historical weight value, at the moment, the state of the weighing device is judged, and when the weight detection value is smaller than the lower limit value (for example-100 g) of the zero point range, the weighing device is judged not to be in the weighing state, and the display unit is controlled to display zero; when the weight detection value is larger than or equal to the lower limit value (for example-100 g) of the zero point range, judging that the weighing device is in a weighing state, acquiring the current weight value of the object to be measured in the inner pot according to the weighing signal output by the weighing sensor, storing the current weight value in the storage unit, and controlling the display unit to display the current weight value.
Thus, if the inner pot is not filled with food materials (such as rice or rice-water mixture), the control unit can control the display unit to display 0 no matter the inner pot is in a standing state (i.e. the inner pot is not lifted by the handle) or a weighing state (i.e. the inner pot is lifted by the handle). When food materials are put into the inner pot and the weight value of the put food materials is larger than the error value which can be identified by the weighing sensor, if the inner pot is in a weighing state, the control unit stores the weight detection value into the storage unit and controls the display unit to display the weight detection value, namely the actual weight value of the put food materials; if the inner pot is in a standing state, the control unit further judges whether the storage unit stores a weight value or not, and when the storage unit stores the weight value, the control unit controls the display unit to display the weight value stored in the storage unit, and when the storage unit does not store the weight value, the display unit is controlled to display 0.

Wherein, the display unit 20 is used for displaying the weight value; the storage unit 40 is used for storing the weight value; the control unit 30 is respectively connected with the weighing sensor 10, the display unit 20 and the storage unit 40, the control unit 30 is used for acquiring a current weight value of an object to be measured in the inner pot according to a weighing signal output by the weighing sensor 10, judging the state of the weighing device 100, and adjusting a historical weight value stored in the storage unit 40 and a historical weight value displayed by the display unit 20 according to the current weight value of the object to be measured in the inner pot 200 when the weighing device 100 is judged to be in a weighing state; and controlling the display unit 20 to display the historical weight value stored in the storage unit 40 when it is determined that the weighing apparatus 100 is not in the weighing state.
According to an embodiment of the present invention, as shown in fig. 4, the weighing device 100 may be disposed in the handle assembly 300 of the inner pot 200, and the handle assembly 300 may be fixedly connected with the inner pot 200 by the fixing assembly 400. Specifically, the handle assembly 300 may include a first handle 301 and a second handle 302, the first handle 301 and the second handle 302 are respectively disposed at both ends of the inner pan 200, the weighing apparatus 100 may include the load cell 10, wherein the load cell 10 may include a first load cell 101 and a second load cell 102, the first load cell 101 and the second load cell 102 may be respectively disposed in the first handle 301 and the second handle 302, the weighing apparatus 100 further includes a control unit 30 and a display unit 20, the control unit 30 may be disposed in the first handle 301 and/or the second handle 302, and the display unit 20 may be disposed on the first handle 301 and/or the second handle 302.
It should be noted that the weighing device 100 is used for weighing food materials (such as rice or rice-water mixture) placed in the inner pot 200, when the handle assembly 300 is lifted upwards from the bottom of the handle assembly 300 by two hands, a force acts on the weighing sensor 10, the weighing sensor 10 deforms to generate an electric signal, and the electric signal is fed back to the control unit 30 as a weighing signal, the control unit 30 can judge a weight value according to the weighing signal, so that a weighing function is realized, and the display unit 20 is controlled to display corresponding contents according to the weight value.
Specifically, when the load cell 10 receives an external force, such as two hands lifting the handle assembly 300 upward from the bottom of the handle assembly 300, the control unit 30 may determine that the weighing apparatus 100 is in a weighing state; when the load cell 10 does not receive an external force, for example, both hands do not contact the handle assembly 300, the control unit 30 may determine that the weighing apparatus 100 is not in a weighing state.
More specifically, after the weighing device 100 obtains the weight value of the object to be measured in the inner pot 200 according to the weighing signal output by the weighing sensor 10, the weight value of the object to be measured is stored in the storage unit 40, whether the weighing sensor 10 receives the external force action is judged, if the weighing sensor 10 receives the external force action, the control unit 30 judges that the weighing device 100 is in the weighing state, and the current weight value of the object to be measured in the inner pot 200 is obtained in real time according to the weighing signal output by the weighing sensor 10. When the obtained current weight value of the object to be measured in the inner pot 200 meets the preset condition, the weight value stored in the storage unit 40 is adjusted to the current weight value, and the display unit 20 is controlled to display the adjusted weight value; when the obtained current weight value of the object to be measured in the inner pot 200 does not satisfy the preset condition, the storage unit 40 is controlled to continue to store the historical weight value (i.e., the original weight value), and the display unit 20 is controlled to display the historical weight value (i.e., the original weight value). On the contrary, if the load cell 10 does not receive the external force, it is determined that the weighing apparatus 100 is not in the weighing state, and the display unit 20 is controlled to display the historical weight value (i.e., the original weight value) stored in the storage unit 40.
According to an embodiment of the present invention, the control unit 30 is further configured to obtain a fluctuation range corresponding to the historical weight value, determine whether the current weight value of the object exceeds the fluctuation range, control the storage unit 40 to store the current weight value and control the display unit 20 to display the current weight value when the current weight value of the object exceeds the fluctuation range, and control the storage unit 40 to store and display the historical weight value displayed by the display unit 20 to remain unchanged when the current weight value of the object does not exceed the fluctuation range.
Specifically, when the weighing device 100 is in the weighing state, the historical weight value stored in the storage unit 40 and the historical weight value displayed by the display unit 20 can be adjusted according to the current weight value of the object to be measured in the inner pot 200. For example, defining the historical weight value stored in the storage unit 40 as M1, a fluctuation range corresponding to the historical weight value M1 may be obtained from the historical weight value M1 and a preset fluctuation threshold value M, where the difference (M1-M) between the historical weight value M1 and the preset fluctuation threshold value M is taken as the lower limit value of the fluctuation range, and the sum (M1+ M) of the historical weight value M1 and the preset fluctuation threshold value M is taken as the upper limit value of the fluctuation range.
When the user lifts the inner pan 200 again through the handle assembly 300 to weigh, obtaining the current weight value of the object to be measured in the inner pan 200 according to the weighing signal output by the weighing sensor 10, defining the current weight value as M2, judging whether the current weight value M2 exceeds the fluctuation range corresponding to the historical weight value M1, if the current weight value M2 exceeds the fluctuation range corresponding to the historical weight value M1, controlling the storage unit 40 to store the current weight value M2, and controlling the display unit 20 to display the current weight value M2; if the current weight value M2 does not exceed the fluctuation range corresponding to the historical weight value M1, the control display unit 20 continues the historical weight value M1.
According to one embodiment of the present invention, the preset fluctuation threshold m may be 0 to 50 g. Wherein, the smaller the preset fluctuation threshold value m is, the higher the weighing precision is. That is, when the preset fluctuation threshold M is 30g, the lower limit value of the fluctuation range of the historical weight value may be (M1-30), and the upper limit value of the fluctuation range of the historical weight value may be (M1+ 30).
According to another embodiment of the present invention, the preset fluctuation threshold M may be a preset ratio η of the historical weight value M1. That is, when the preset fluctuation threshold M is the preset ratio η of the historical weight value M1, that is, M1 η, the lower limit value of the fluctuation range of the historical weight value may be (M1-M1 η), and the upper limit value of the fluctuation range of the historical weight value may be (M1+ M1 η).
According to an embodiment of the present invention, the preset ratio η may be 5% to 10%, and the preset ratio η decreases as the weight-indicated value M1 increases.
According to an embodiment of the present invention, the control unit 30 is further configured to control the display unit 20 to display 0 if the current weight value belongs to the preset zero point range when the storage unit 40 is controlled to store and control the display unit 20 to display the current weight value.
Specifically, when the weighing device 100 of the cooking apparatus is in the weighing state, the weighing sensor 10 can output a weighing signal in real time, the control unit 30 obtains the current weight value of the object to be measured in the inner pot 200 according to the weighing signal output by the weighing sensor 10, and determines whether the current weight value belongs to the preset zero point range, if the current weight value is determined to belong to the preset zero point range, it is indicated that the current weight value is near the zero point, and is lower than an error value that can be recognized by the weighing sensor 10, at this time, the control unit 30 controls the display unit to display 0.
According to an embodiment of the present invention, the predetermined zero range may be [ -M, + M ], and M may range from 0g to 100 g. Assuming that M is 100g, the lower limit value of the zero point range is-100 g, and the upper limit value of the zero point range is 100 g. Wherein, the upper limit value + M of the zero point range represents an error value that the load cell 10 can recognize, that is, if the weight detection value is greater than the upper limit value + M of the zero point range, the load cell 10 can accurately recognize the weight value of the food material placed in the inner pot 200.
Note that the smaller the value of M, the higher the weighing accuracy of the load cell 10.
According to an embodiment of the present invention, the control unit 30 is further configured to determine a state of the weighing device 100 according to a current weight value of the object to be measured in the inner pot 200, wherein if the current weight value is smaller than a lower limit value of the preset zero point range, it is determined that the weighing device 100 is not in the weighing state; and if the current weight value is greater than or equal to the lower limit value of the preset zero point range, judging that the weighing device 100 is in a weighing state.
Specifically, in a preferred embodiment of the present invention, assuming that M is 100g, the zero range of the weighing apparatus is [ -100g, +100g ]. After the weighing device of the cooking apparatus is started, the weighing sensor 10 can output a weighing signal in real time, the control unit 30 obtains the current weight value of the object to be measured in the inner pot according to the weighing signal output by the weighing sensor 10, and judges whether the current weight value belongs to the range of [ -100g, +100g ], if the current weight value is smaller than the lower limit value of the zero point range-100 g, the control unit 30 judges that the weighing device 100 is not in the weighing state, that is, the handle assembly 300 of the inner pot 200 is not lifted up by the handle, and at this time, the control unit 30 controls the display unit 20 to display the historical weight value (that is, the original weight value) stored in the storage unit 40. If the current weight value is greater than or equal to the lower limit value of the preset zero point range, for example, -100g, it is determined that the weighing device 100 is in the weighing state, that is, the inner pot 200 is lifted by the handle assembly 300, and at this time, the historical weight value stored in the storage unit and the historical weight value displayed by the display unit are adjusted according to the current weight value of the object to be measured in the inner pot.
When the cooking equipment is in a weighing state, the weighing sensor can output a weighing signal in real time, the current weight value of an object to be measured in the inner pot is obtained according to the weighing signal output by the weighing sensor, if the weight detection value is judged to be larger than the upper limit value + M (for example +100g) of the zero point range, the fact that food materials (for example, rice or a rice-water mixture) are placed in the inner pot of the weighing device is indicated, and the weight value of the placed food materials is higher than an error value which can be identified by the weighing sensor. Further, the historical weight value stored in the storage unit and the historical weight value displayed by the display unit are adjusted according to the current weight value of the object to be measured in the inner pot, if the current weight value of the object to be measured exceeds the fluctuation range, the current weight value is stored in the storage unit, and the display unit is controlled to display the current weight value, wherein the current weight value is the actual weight value of the food material put into the inner pot; and if the current weight value of the object to be measured does not exceed the fluctuation range, controlling the historical weight value stored in the storage unit and displayed by the display unit to be kept unchanged.

Specifically, when the weighing apparatus 100 is weighing for the first time, the storage unit 40 usually does not store a historical weight value, and at this time, the control unit 30 determines the state of the weighing apparatus 100, and when the weight detection value is smaller than a lower limit value (e.g., -100g) of the zero point range, the control unit 30 determines that the weighing apparatus 100 is not in the weighing state, and controls the display unit 20 to display zero; when the weight detection value is greater than or equal to the lower limit value (e.g., -100g) of the zero point range, the control unit 30 determines that the weighing device 100 is in the weighing state, obtains the current weight value of the object to be measured in the inner pot 200 according to the weighing signal output by the weighing sensor 10, stores the current weight value in the storage unit 40, and controls the display unit 20 to display the current weight value.

When the food material is put into the inner pot 200 and the weight value of the put food material is greater than the error value that can be identified by the weighing sensor 10, if the inner pot 200 is in the weighing state, the control unit 30 stores the weight detection value into the storage unit 40 and controls the display unit 20 to display the weight detection value, that is, the actual weight value of the put food material; if the inner pot 200 is in the standing state, the control unit 30 further determines whether the storage unit 40 stores the weight value, when the storage unit 40 stores the weight value, the control unit 30 controls the display unit 20 to display the weight value stored in the storage unit 40, and when the storage unit 40 does not store the weight value, the control unit 20 controls the display unit 20 to display 0.
