Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a control method for household appliances, the household appliances, and a computer-readable storage medium. Background Art

[0002] In recent years, a number of heating appliances have appeared on the market, including small, all-glass appliances for health and wellness, such as glass tea makers and glass health kettles. However, due to limitations in the manufacturing process or product structure of glass appliances, they lack temperature sensors and, therefore, cannot be used for heating control. Instead, heating control is achieved by turning the thermostat in the appliance on or off.

[0003] The thermostat automatically disconnects when it reaches a certain temperature, and each time it disconnects, it takes 3-5 minutes to restore connectivity. Since heating can only be performed when connectivity is restored, the water boiling time is very long. In related art, heating is performed in the same manner regardless of how many times the thermostat is restored, without adaptive adjustment. This can result in the thermostat maintaining connectivity for a short time, causing frequent disconnections, or maintaining connectivity for a long time, causing the thermostat to remain connected all the time, resulting in significant heat loss.

[0004] Frequent disconnection of the thermostat not only affects the service life of the thermostat itself, but also causes the entire water boiling time to be very long. Therefore, the present invention at least solves the following technical problem: how to reduce the number of times the thermostat is frequently disconnected. Summary of the Invention

[0013] Optionally, the step of adjusting the operating parameters of the household appliance according to the comparison result includes:

[0014] According to the comparison result, the operating parameter is increased or decreased.

[0015] Optionally, the step of increasing or decreasing the operating parameter according to the comparison result includes:

[0016] When the comparison result shows that the continuous connection time is greater than the rated connection time, increasing the operating parameter according to a preset increase step;

[0017] When the comparison result is that the continuous connection time is less than the rated connection time, the operating parameter is reduced according to a preset reduction step.

[0018] Optionally, after the step of adjusting the operating parameters of the household appliance according to the comparison result, the method further includes:

[0019] When the thermostat is restored to connectivity, the household appliance is controlled to operate according to the rated power and the adjusted power in sequence, wherein the duration for which the household appliance operates according to the rated power is the operating duration, and the operating parameters include the power and the operating duration.

[0020] Optionally, when the absolute value of the difference is greater than a preset threshold, the step of adjusting the operating parameters of the household appliance includes:

[0021] When the absolute value of the difference is greater than a preset threshold, determining a current heating mode of the household appliance;

[0022] When the current heating mode is the first mode, adjusting the target duration for the household appliance to operate at rated power; after operating at the rated power for the target duration, adjusting the power of the household appliance, the operating parameters including the target duration and the power;

[0023] When the current heating mode is the second mode, the power of the household appliance is adjusted, and after the household appliance is restored to connectivity, the household appliance is controlled to operate according to the adjusted power, and the operating parameter is the power.

[0024] Optionally, before the step of obtaining the continuous connection time of the thermostat when detecting that the thermostat of the household appliance is disconnected, the method further includes:

[0025] When it is detected that the home appliance starts heating, the home appliance is controlled to operate according to the rated power, and it is detected whether the thermostat of the home appliance is disconnected.

[0026] In addition, to achieve the above-mentioned object, the present invention further provides a home appliance, comprising a thermostat, a memory, a processor, and a control program for the home appliance stored in the memory and executable on the processor, wherein:

When the home appliance operates according to the adjusted operating parameters, the corresponding absolute value of the difference is less than or equal to the preset threshold. The absolute value of the difference indicates whether the continuous connection duration is too long or too short. If the absolute value of the difference is too long or too short, the absolute value of the difference is greater than the preset threshold. If the absolute value of the difference is greater than the preset threshold, it may indicate that the thermostat's continuous connection duration is too long, resulting in significant heat loss, or it may indicate that the thermostat's continuous connection duration is too short, resulting in frequent disconnections. Therefore, when the absolute value of the difference is greater than the preset threshold, the operating parameters of the household appliance are adjusted. When the household appliance operates according to the adjusted operating parameters, the corresponding absolute value of the difference is less than or equal to the preset threshold, so that after the thermostat is restored to connectivity, large heat loss is avoided and frequent disconnection of the thermostat is avoided.

[0064] Reference Figure 2 A first embodiment of the present invention provides a method for controlling a household appliance, the method comprising:

[0065] Step S10, when detecting that the thermostat of the household appliance is disconnected, obtaining the continuous connection time of the thermostat;

[0066] Currently, some home appliances lack temperature sensors due to structural or process limitations. This means they cannot detect temperature using sensors or perform heating control based on the detected temperature. Instead, they use thermostats to implement heating control. When a thermostat detects that the ambient temperature has reached a certain threshold, it automatically disconnects and then automatically resumes operation after a period of time. By changing the operating parameters of the home appliance, such as the power, the temperature of the environment in which the thermostat operates can be altered, thereby adjusting the timing of the thermostat disconnection. In related art, placing a thermostat in a specific location within the home appliance can mitigate the effect of the temperature of the heated object on the ambient temperature detected by the thermostat, thereby heating the object to a specific temperature. However, these related art heating controls are implemented according to a preset program and fixed operating parameters. Due to the diverse temperatures in the environment in which the home appliance operates, the thermostat may disconnect too early or too late. For example, when the ambient temperature is low, the thermostat disconnects too late, causing the heating circuit to remain in a prolonged heating state, resulting in high heat loss. Alternatively, when the ambient temperature is high, the thermostat disconnects too early, resulting in frequent disconnections.

[0067] To address the above issues, this embodiment uses the thermostat's continuous connection duration to represent the ambient temperature state. When the ambient temperature is high, the continuous connection duration is low, and when the ambient temperature is low, the continuous connection duration is high. The absolute value of the difference between the continuous connection duration and the rated connection duration is further determined, and this absolute value is compared with a preset threshold. If the absolute value of the rated difference is greater than the preset threshold, it indicates that the continuous connection duration may be too high or too low. Therefore, this embodiment adjusts the operating parameters of the household appliance so that when the household appliance operates according to the adjusted operating parameters, the corresponding absolute value of the difference is less than or equal to the preset threshold.

[0068] The continuous connection time is the time the thermostat was connected before it was disconnected. In this embodiment, the continuous connection time mainly refers to the time the thermostat was last in the continuous connection state.

[0069] Step S20, determining the absolute value of the difference between the continuous connection time and the rated connection time;

[0070] The rated connection duration is the length of time a thermostat remains connected when the appliance is operating under rated conditions. For example, it has been determined that the rated connection duration for a particular appliance, under rated operating conditions that minimize system heat loss and maximize temperature rise, is 9 minutes. Based on this rated connection duration, we can determine whether the continuous connection duration is too long or too short, indirectly detecting whether the ambient temperature is too low or too high, and using the absolute value of the difference as feedback to adjust operating parameters.

[0071] It is understood that this embodiment uses the absolute value of the difference to represent the degree to which the continuous connection duration deviates from the rated connection duration. This is primarily because the continuous connection duration may be too high or too low. In another embodiment, the absolute value of the difference can be replaced with the difference, while still remaining within the spirit of this embodiment. This is because determining the difference between the continuous connection duration and the rated connection duration and comparing the difference with another preset difference is essentially comparing the degree to which the continuous connection duration deviates from the rated connection duration, simply performing a simple mathematical transformation.

[0072] Step S30, when the absolute value of the difference is greater than a preset threshold, adjusting the operating parameters of the household appliance so that the household appliance operates according to the adjusted operating parameters after the thermostat is restored to connectivity, wherein when the household appliance operates according to the adjusted operating parameters, the corresponding absolute value of the difference is less than or equal to the preset threshold.

[0073] The preset threshold is the maximum absolute value of the difference allowed under the rated operating conditions. The maximum absolute value of the difference is the absolute value of the difference between the continuous connection time that meets the rated operating conditions and the rated connection time. For example, under the rated operating conditions, the rated connection time is 9 minutes, and the preset threshold is 1 minute. This is equivalent to meeting the degree of deviation under the rated operating conditions when the continuous connection time is between 8 minutes and 10 minutes. If it is less than 8 minutes or greater than 10 minutes, it does not meet the degree of deviation under the rated operating conditions. That is, when the absolute value of the difference is greater than 1 minute, the continuous connection time deviates greatly, and the temperature of the environment in which the household appliance is located deviates too much from the ambient temperature under the rated operating conditions, resulting in excessive heat loss of the household appliance, or frequent disconnection of the thermostat. At this time, it is necessary to adjust the operating parameters of the household appliance.

[0074] If the absolute value of the difference is greater than a preset threshold, the operating parameters of the home appliance, such as power, are adjusted. By adjusting the operating parameters, when the home appliance operates according to the adjusted operating parameters after the thermostat is restored, the corresponding absolute value of the difference is less than the preset threshold.

[0075] When it is detected that the absolute value of the difference is greater than a preset threshold, the operating parameter can be adjusted according to the preset adjustment step size. The operating parameter, such as power, can specifically be increased or decreased, so that when the household appliance operates according to the adjusted operating parameter, the corresponding absolute value of the difference is less than or equal to the preset threshold. A mapping relationship between the absolute value of the difference, the preset threshold, and the preset adjustment step size can be pre-established through testing, so that the preset adjustment step size is determined based on the absolute value of the difference. For example, the absolute value of the difference is a, the preset threshold is b, and it is determined that when the preset adjustment step size is power p1, the household appliance can operate at a power of p+p1 with the corresponding absolute value of the difference being less than or equal to a.

[0076] To improve the accuracy of the adjustment, the operating parameters can be adjusted repeatedly. Each time the thermostat is disconnected and the absolute value of the difference is detected to be greater than a preset threshold, the home appliance can increase or decrease the operating parameters and repeat the above process. That is, when the thermostat is disconnected again, the absolute value of the difference is re-detected to see if it is greater than the preset threshold. The above process is repeated until the home appliance stops adjusting when the absolute value of the difference is less than or equal to the preset threshold when the home appliance is operating according to the adjusted operating parameters.

[0077] Optionally, when the household appliance is in different heating modes, the corresponding preset thresholds may be different. For example, in the rapid heating mode, the preset threshold can be set to be relatively large. In the boiling mode, the preset threshold can be set to be relatively small. In the rapid heating mode, when adjusting the operating parameters, it is necessary to make the household appliance heat up quickly and lose less heat. Therefore, the continuous connection time cannot be too long or too short. Too long may lead to large heat loss, and too short may lead to slow heating. Therefore, it is necessary to set a larger preset threshold so that the absolute value of the difference fluctuates within a larger range. In the boiling mode, heating needs to be performed slowly. At this time, the characteristic of rapid heating does not need to be met. At this time, it is mainly possible to avoid excessive heat loss and thus set a smaller preset threshold so that the absolute value of the difference fluctuates within a smaller range.

[0078] Therefore, the current heating mode of the home appliance can be obtained and the preset threshold corresponding to the current heating mode can be determined. Heating modes include quick heating mode and boiling mode.

[0079] By adopting the above method, by adjusting the operating parameters of the household appliance, when the household appliance operates according to the adjusted operating parameters, the corresponding absolute value of the difference is less than or equal to the preset threshold value, thereby making it possible to increase the temperature and prevent the thermostat from tripping frequently, reducing the number of times the thermostat is frequently disconnected, and adaptively adjusting to the environment in which the household appliance is located, thereby compensating for the effects of different ambient temperatures, differences in thermostat consistency, differences in heating power, and differences in assembly.

[0080] Optionally, when it is detected that the home appliance is turned on for heating, the home appliance is controlled to operate at rated power, and it is detected whether the thermostat of the home appliance is disconnected.

[0081] In this embodiment, upon detecting that the thermostat of a home appliance is disconnected, the duration of the thermostat's continuous connection is obtained, and the absolute value of the difference between the continuous connection duration and the rated connection duration is determined. When the absolute value of the difference is greater than a preset threshold, the operating parameters of the home appliance are adjusted so that the home appliance operates according to the adjusted operating parameters after the thermostat is restored to connection. When the home appliance operates according to the adjusted operating parameters, the corresponding absolute value of the difference is less than or equal to the preset threshold. The absolute value of the difference indicates whether the continuous connection duration is too long or too short. If the absolute value of the difference is too long or too short, the absolute value of the difference is greater than the preset threshold. If the absolute value of the difference is greater than the preset threshold, it may be that the duration of the thermostat's continuous connection is too long, resulting in significant heat loss, or it may be that the duration of the thermostat's continuous connection is too short, resulting in frequent disconnections. Therefore, when the absolute value of the difference is greater than the preset threshold, the operating parameters of the household appliance are adjusted. When the household appliance operates according to the adjusted operating parameters, the corresponding absolute value of the difference is less than or equal to the preset threshold, so that after the thermostat is restored to connectivity, large heat loss is avoided and frequent disconnection of the thermostat is avoided.

[0082] Reference Figure 3 The second embodiment of the present invention provides a method for controlling household appliances. Figure 2 In the first embodiment shown, step S30 includes:

[0083] Step S31, when the absolute value of the difference is greater than the preset threshold, comparing the continuous connection time with the rated connection time to obtain a comparison result;

[0084] If the continuous connection time is longer than the rated connection time, heat loss may be excessive. In this case, you need to adjust the operating parameters to reduce heat loss. If the continuous connection time is shorter than the rated connection time, frequent disconnections may occur. In this case, you need to adjust the operating parameters to reduce the number of frequent disconnections. Therefore, it is necessary to compare the continuous connection time with the rated connection time.

[0085] Step S32: adjusting the operating parameters of the household appliance according to the comparison result, wherein the operating parameters include power and / or operating time, and the operating time is the time during which the household appliance operates at rated power.

[0086] After the comparison result is obtained, the operating parameters of the household appliance are adjusted according to the comparison result. The operating parameters include power and / or operating time, and the power can be changed by changing the duty cycle.

[0087] The longer the appliance runs at rated power after it's restored, the faster the temperature rises and the more often the thermostat disconnects. Conversely, the shorter the run time, the slower the temperature rises and the fewer times the thermostat disconnects. However, the longer the heating period, the higher the heat loss. In certain heating modes, such as rapid heating mode, running directly at a power lower than the rated power may result in slower heating, affecting the rapid heating effect. However, running directly at the rated power may cause the thermostat to disconnect more frequently. Therefore, it is necessary to adjust the run time to increase or decrease the absolute value of the difference less than or equal to the preset threshold.

[0088] The higher the power, the more frequent disconnections occur, while the lower the power, the greater the heat loss. Therefore, it is necessary to adjust the power to increase or decrease the absolute value of the difference less than or equal to the preset threshold.

[0089] In the process of adjusting the operating parameters based on the comparison results, the operating parameters of the household appliance are obtained and the operating parameters are increased or decreased based on the comparison results. Specifically, if the comparison result shows that the continuous connection duration is greater than the rated connection duration, the operating parameters are increased by a preset step size; if the comparison result shows that the continuous connection duration is less than the rated connection duration, the operating parameters are decreased by a preset step size.

[0090] When the thermostat is restored to connectivity, the home appliance is controlled to operate according to the rated power and the adjusted power in sequence. The time during which the home appliance operates at the rated power is the operating time, and the operating parameters include power and operating time.

[0091] In a specific scenario, after testing, a household appliance was found to have a rated connection time of 9 minutes in the rapid heating mode, and a preset threshold of 1 minute. That is, when the continuous connection time is between 8 minutes and 10 minutes, the system heat loss of the household appliance is minimal and the temperature rises fastest. In the initial working stage, the timing starts, and the heating components are heated at the rated power. When it is detected that the thermostat is disconnected, the continuous connection time t1 is recorded. After the thermostat is restored to connection, it is heated in turn according to the rated power and the adjusted power. The heating time according to the rated power is (t1-30s), 30s is the preset reduction step, and the power is Px. At this stage, since there was no corresponding power before, the preset power is selected as Px. The thermostat is continuously checked for disconnection. When the thermostat is detected to be disconnected again, the continuous connection duration is updated, and the absolute value of the difference between the updated continuous connection duration and the rated connection duration is determined. When the absolute value of the difference is less than or equal to a preset threshold, the operating parameter adjustment is stopped. When the absolute value of the difference is greater than the preset threshold, the operating duration and current power of the thermostat when it was last connected are obtained. The continuous connection duration and the rated connection duration are compared. If the continuous connection duration is greater than the rated connection duration, the operating duration and current power are increased. If the continuous connection duration is less than the rated connection duration, the operating duration and current power are reduced. For example, if the continuous connection duration is determined to be greater than the rated connection duration based on the operating duration and current power of the thermostat when it was last connected, the operating duration is increased to (t1-25s) and Px is increased. If the continuous connection duration is determined to be less than the rated connection duration, the operating duration is reduced to (t1-35s) and Px is reduced. By adopting the above method, the operating time and power are repeatedly adjusted so that the absolute value of the difference between the continuous connection time of the thermostat and the rated connection time is less than or equal to the preset threshold.

[0092] In another specific scenario, the heating mode of the household appliance is a boiling mode. First, when heating at room temperature, heating is performed according to the rated power. When the thermostat is detected to be disconnected, the connection time before the disconnection is recorded as the rated connection time. When the ambient temperature is too low, the continuous connection time of the thermostat will be greater than the rated connection time. At this time, in order to improve the boiling effect in a low-temperature environment, the power is increased. When the ambient temperature is too high, the continuous connection time of the thermostat will be less than the rated connection time. In order to improve the boiling effect in a high-temperature environment and prevent overflow, the power is reduced. In the above manner, the ambient temperature can be taken into account during the boiling stage to solve the problems of too long low-temperature heating time and high-temperature overflow.

[0093] In this embodiment, when the absolute value of the difference is greater than a preset threshold, the continuous connection duration is compared with the rated connection duration to obtain a comparison result. Based on the comparison result, operating parameters of the home appliance are adjusted. The operating parameters include power and / or operating duration, with the operating duration being the duration that the home appliance operates at rated power after connectivity is restored. This allows the power and / or operating duration of the home appliance to be adjusted to reduce heat loss and the number of times the thermostat frequently disconnects.

[0094] Reference Figure 4 The third embodiment of the present invention provides a method for controlling household appliances. Figure 2 In the first embodiment shown, step S30 includes:

[0095] Step S33, when the absolute value of the difference is greater than a preset threshold, determining the current heating mode of the household appliance;

[0096] The current heating mode includes a first mode and a second mode. The first mode may be a fast accelerated heating mode, and the second mode may be a slow heating mode, such as a boiling mode. In different heating modes, different operating parameters need to be adjusted.

[0097] Step S34, when the current heating mode is the first mode, adjusting the operating time of the household appliance at the rated power and the power of the household appliance after running for the operating time, the operating parameters including the operating time and the power;

[0098] The first mode is the fast heating mode. At this time, in order to increase the heating speed, it is necessary to control the household appliances to operate in accordance with the rated power and the adjusted power in turn. The running time is the length of time it runs at the rated power. When other conditions remain unchanged, the longer the running time, the faster the heating speed, but the heat loss may be greater. When other conditions remain unchanged, the greater the power, the faster the heating speed, and the smaller the power, the smaller the heating speed. Based on the above principle, when the continuous connection time is greater than the rated connection time, the running time and power are increased. When the continuous connection time is less than the rated connection time, the running time and power are reduced.

[0099] Step S35: When the current heating mode is the second mode, adjust the power of the household appliance, and the operating parameter is the power.

[0100] The second mode is slow heating mode. In this mode, the power of the home appliance is adjusted to ensure the cooking effect, and the home appliance is controlled to operate at the adjusted power. When the ambient temperature is too low and the continuous connection time is longer than the rated connection time, the power is increased to improve the cooking effect in low-temperature environments. When the ambient temperature is too high and the continuous connection time is less than the rated connection time, the power is reduced to improve the cooking effect in high-temperature environments and prevent overflow.

[0101] In this embodiment, the current heating mode of the home appliance is determined when the absolute value of the difference is greater than a preset threshold. When the current heating mode is the first mode, the operating time of the home appliance at rated power and the power after the home appliance has been running for the specified time are adjusted, with the operating parameters including the operating time and power. When the current heating mode is the second mode, the power of the home appliance is adjusted, with the operating parameter being the power. This allows for different control modes to be implemented, improving the heating effect in different heating modes while reducing the number of frequent thermostat disconnections.
