Based on the above-described structure, various embodiments of a control method of a steam generator are proposed.
Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of a steam generator according to a first embodiment of the present invention.
While a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different sequence than that shown or described herein.
The steam generator is assembled in the dish washing machine and comprises a steam generating cavity, and the steam generating cavity is connected with a water supply device through a water inlet pipe. The steam generator is used for generating steam, and the steam generation cavity is used for storing the water generating the steam. Specifically, the water inlet of the steam generation cavity is connected with the water outlet of the water supply device through a water inlet pipe. And a water suction pump is arranged in a water inlet of the steam generation cavity and is used for supplementing water when the steam generation cavity needs water. The water supply device can be a water storage tank arranged in the dish washing machine and can also be a water tap, namely, the steam generation cavity is directly connected with the water tap through a water inlet pipe, and when the steam generator needs water supplement, water supplement is directly carried out through the water tap.
The control method of the steam generator includes:
and step S10, detecting the current temperature of the steam generator according to the detection instruction after detecting the detection instruction for detecting the temperature of the steam generator.
And when the dish washing machine detects a detection instruction for detecting the current temperature of the steam generator, the dish washing machine detects the current temperature of the steam generator according to the detection instruction. Wherein the detection instruction can be triggered by the dishwasher in real time or at regular time. When the dishwasher triggers the detection instruction at regular time, the time length corresponding to the regular time can be set by the user according to specific needs, and the embodiment does not specifically limit the time length corresponding to the regular time triggering detection instruction. The dishwasher may detect the current temperature of the steam generator through a built-in temperature sensor. In the present embodiment, the Temperature sensor includes, but is not limited to, an ntc (negative Temperature Coefficient) Temperature sensor and a PTC (Positive Temperature Coefficient) Temperature sensor.
And step S20, if the current temperature is higher than a first preset temperature, triggering a water supplementing instruction, and controlling water of the water supply device to be injected into the steam generation cavity through the water inlet pipe according to the water supplementing instruction so as to supplement water for the steam generator.
When the dishwasher detects the current temperature of the steam generator, the dishwasher judges whether the current temperature of the steam generator is greater than a first preset temperature. If the current temperature of the steam generator is higher than the first preset temperature, the dish washing machine automatically triggers a water supplementing instruction, and water of the water supply device is controlled to be injected into the steam generation cavity through the water inlet pipe according to the water supplementing instruction so as to supplement water for the steam generator. The first preset temperature can be set according to specific needs, such as 98 ℃ (celsius), 105 ℃ (108 ℃), or the like.
Further, if the current temperature of the steam generator is less than or equal to the first preset temperature, the dishwasher continues to detect the current temperature of the steam generator.
Further, step S20 includes:
step a, if the current temperature is higher than a first preset temperature, triggering a water supplementing instruction, and detecting the water level in the steam generation cavity according to the water supplementing instruction.
And b, determining the water supplement amount according to the water level in the steam generation cavity and the volume of the steam generation cavity.
Further, in order to avoid that the amount of water supplemented by the steam generator is too small or too much in the water supplementing process of the steam generator, after the dish-washing machine determines that the current temperature of the steam generator is higher than the first preset temperature, the dish-washing machine automatically triggers a water supplementing instruction, detects the water level in the steam generation cavity according to the water supplementing instruction, and obtains the volume of the steam generation cavity. Specifically, the dishwasher may detect the water level in the steam generation chamber through a water level sensor. The volume of the steam generating chamber is preset.
And after the water level in the steam generation cavity and the volume of the steam generation cavity are obtained, the dishwasher determines the water supplementing quantity of the steam generation cavity according to the obtained water level and volume. It can be understood that after the water level and the volume in the steam generating cavity are determined, the amount of water supplement required by the steam generating cavity can be calculated. If the current water level is 2, the total water level is 5, and the volume of the steam generation cavity is a, the water supplement amount is a ÷ 5 × 2.
And c, calculating the water supplementing duration according to the water supplementing quantity and the water flow speed of the water in the water inlet pipe.
And d, controlling the water of the water supply device to be injected into the steam generation cavity through the water inlet pipe according to the water supplementing duration so as to supplement water to the steam generator.
After the water replenishing amount of the steam generator is determined, the dish washing machine calculates the required water replenishing time length according to the water replenishing amount required by the steam generator and the water flow speed of water in the water inlet pipe, and specifically, the dish washing machine divides the value corresponding to the water replenishing amount by the water flow speed to obtain the water replenishing time length. If the water replenishing amount needed by the steam generator corresponds to the value A and the water flow speed is B, the water replenishing time period is A/B.
And when the water supplementing time is obtained through calculation, the dish washing machine controls water of the water supply device to be injected into the steam generation cavity through the water inlet pipe according to the calculated water supplementing time so as to supplement water for the steam generator. Specifically, the dishwasher starts a timer when starting to perform a water replenishing operation. When the time counted by the timer is equal to the water replenishing time length, the water of the water supply device is controlled to be temporarily stopped to be injected into the steam generation cavity through the water inlet pipe, and the water replenishing operation is finished, so that the amount of water in the steam generation cavity can be controlled not to be too small and not too much.
And step S30, if the water replenishing times of the steam generator in the preset time period are larger than the preset water replenishing times, closing the steam generator.
After the water is supplemented to the steam generator, the dish washing machine judges whether the water supplementing frequency of the steam generator in the preset time is larger than the preset water supplementing frequency. If the water replenishing times of the steam generator in the preset time are larger than the preset water replenishing times, the dish washing machine automatically triggers a closing instruction, and the steam generator is closed according to the closing instruction. The preset time duration can be the time duration of the steam generator generating steam and can also be the time duration set by a user according to needs. The preset time period may be C, for example, when the steam generator generates steam once at time C. The preset water replenishing times can be set according to specific needs, such as 3 times, 5 times or 6 times. It is understood that when the preset water replenishing time is 3 times, i.e., 3 times over the preset time period, the temperature of the steam generator is greater than the first preset temperature.
Further, if the number of times of water supply of the steam generator within the preset time period is less than or equal to the preset number of times of water supply, the dishwasher continues to detect the current temperature of the steam generator.
Further, when the water supply device is mounted in the dishwasher, the control method of the steam generator further includes:
and e, detecting the water level of the water supply device, and judging whether the water level of the water supply device is lower than a preset water level.
And f, if the water level of the water supply device is lower than the preset water level, outputting prompt information to prompt a user that water needs to be supplied to the water supply device according to the prompt information.
When water supply installation assembles in the dish washer, at this moment, water supply installation can be a storage water tank in the dish washer, in order to avoid water supply installation to be in the state of lacking water, when steam generator needs the moisturizing, because lack of water among the water supply installation, the condition that leads to steam generator moisturizing to fail appears, when making steam generator need the moisturizing, can in time give steam generator moisturizing, the water level among the real-time or regularly detecting water supply installation of dish washer, and judge whether water supply installation's water level is less than predetermined water level. If the water level of the water supply device is lower than the preset water level, the dish washing machine outputs prompt information to prompt a user that water needs to be supplied to the water supply device according to the prompt information. The preset water level may be set by a user according to specific needs, and is not particularly limited in this embodiment. The output mode of the prompt message can be a voice mode or a mode of flashing an indicator light, and the like. If the dishwasher outputs a voice of 'water shortage of the water storage tank' to prompt a user to replenish water for the water supply device.
Further, if the water level of the water supply device is higher than or equal to the preset water level, the dishwasher continues to detect the water level of the water supply device.
This embodiment is through detecting steam generator's current temperature, and when current temperature was greater than first predetermined temperature, the moisturizing instruction of automatic trigger was carried out the moisturizing to steam generator according to the moisturizing instruction, and when steam generator was greater than predetermined moisturizing number of times in predetermineeing the length of time, closed steam generator. The steam generator is prevented from being in a dry-burning state due to water shortage of the steam generator, the steam generator is prevented from being in a high-temperature state for multiple times, the steam generator is prevented from being damaged, the steam generator is protected, and the service lives of the steam generator and the dish-washing machine are prolonged.
Further, a second embodiment of a control method of a steam generator of the present invention is presented.
The second embodiment of the control method of the steam generator is different from the first embodiment of the control method of the steam generator in that, referring to fig. 3, the control method of the steam generator further includes:
step S40, if the current temperature is higher than a second preset temperature, the steam generator is turned off, wherein the second preset temperature is higher than the first preset temperature.
If the current temperature of the steam generator is determined to be higher than the second preset temperature, the dishwasher automatically triggers a closing instruction, and the steam generator is closed according to the closing instruction. Wherein the second preset temperature is greater than the first preset temperature. For example, the second preset temperature can be set to 135 ℃, 140 ℃ or 142 ℃ and the like.
It should be noted that the dishwasher detects the current temperature of the steam generator in real time or at regular time, so that the dishwasher may continue to detect the current temperature of the steam generator after the dishwasher replenishes water to the steam generator. If the current temperature is determined to be higher than the first preset temperature, the dish washing machine can replenish water to the steam generator; if the current temperature is higher than the second preset temperature, the dishwasher turns off the steam generator.
The embodiment can further protect the steam generator and prolong the service life of the steam generator and the dish washer by closing the steam generator when the current temperature of the steam generator is higher than the second preset temperature so as to avoid damaging the steam generator when the steam generator is in a high-temperature state.
Further, a third embodiment of a control method of a steam generator of the present invention is proposed.
The third embodiment of the control method of the steam generator is different from the first and/or second embodiment of the control method of the steam generator in that, referring to fig. 4, the control method of the steam generator further includes:
step S50, detecting a current temperature of the steam generator after the steam generator is turned off.
When the dishwasher turns off the steam generator, the dishwasher detects a current temperature of the turned-off steam generator. Note that, the step S50 may be executed after the step S30, or may be executed after the step S40.
Step S60, if the current temperature is higher than a third preset temperature, determining that the steam generator is in a fault state, where the third preset temperature is higher than the second preset temperature.
And after the dishwasher detects the current temperature of the closed steam generator, the dishwasher judges whether the current temperature of the closed steam generator is greater than a third preset temperature. And if the current temperature of the steam generator after being shut down is greater than the third preset temperature, the dishwasher determines that the steam generator is in a fault state. The third preset temperature is greater than the second preset temperature, for example, the third preset temperature may be set to 170 ℃, 180 ℃, 183 ℃ or the like. It will be appreciated that when the steam generator is turned off, only the software of the steam generator is turned off and the hardware of the steam generator is still running. Further, when the steam generator is in a normal state, the temperature of the steam generator may become a normal temperature after the steam generator is turned off; if it is detected that the temperature of the steam generator is not lowered but is raised after the steam generator is turned off, it may be determined that the steam generator is in a failed state.
Further, if the current temperature of the steam generator after being turned off is less than or equal to a second preset temperature, the dishwasher continues to detect the current temperature of the steam generator after being turned off.
Further, the dishwasher may also output a warning message when it detects that the steam generator is in a malfunction state once.
The embodiment continuously detects the temperature of the steam generator after the steam generator is closed, and when the current temperature of the steam generator after the steam generator is closed is higher than the third preset temperature, the steam generator is determined to be in a fault state, so that whether the steam generator is in the fault state or not can be detected in real time, and the maintenance of the steam generator is facilitated.
Further, in order to improve the accuracy of detecting whether the steam generator is in the fault state after the steam generator is turned off, the dishwasher detects the current temperature of the steam generator after the steam generator is turned off for a preset time period, and judges whether the current temperature of the steam generator after the steam generator is turned off is greater than a third preset temperature. The preset time period can be set according to specific needs, such as 0.5 minute, 1 minute, or 3 minutes.
Further, a fourth embodiment of a control method of a steam generator of the present invention is proposed.
The fourth embodiment of the control method of a steam generator is different from the third embodiment of the control method of a steam generator in that the control method of a steam generator further includes:
and h, calculating the failure times of the steam generator in the failure state.
And i, if the failure frequency is greater than or equal to the preset failure frequency, outputting alarm information to prompt a user that the steam generator is in a failure state according to the alarm information.
After determining that the steam generator is in the malfunction state, the dishwasher calculates the number of malfunctions of the steam generator in the malfunction state and determines whether the number of malfunctions is greater than or equal to a preset number of malfunctions. If the failure frequency of the steam generator is more than or equal to the preset failure frequency, the dishwasher outputs alarm information to prompt a user that the steam generator is in a failure state according to the alarm information. Wherein the dishwasher may calculate the number of malfunctions of the steam generator in a malfunction state according to the timer. Every time the steam generator is in a failure state once, 1 is added to the value of the timer. And when the value of the timer is greater than or equal to the preset failure times, initializing the timer to enable the value corresponding to the timer to be 0. It is understood that the initial value of the timer is 0. The preset failure times can be set according to specific needs, such as 2 times, 3 times or 4 times. The output mode of the alarm information can be a voice mode or a mode of flashing an indicator light and the like.
It should be noted that, in this embodiment, when the dishwasher detects that the steam generator is in a failure state, the dishwasher does not output the warning message to prompt the user that the steam generator is in the failure state, and only when the failure frequency of the steam generator in the failure state is greater than or equal to the preset failure frequency, the dishwasher outputs the warning message. Since the dishwasher detects that the steam generator is in a malfunction state, which may be a problem in a certain process during the operation of the steam generator, the problem may be solved by restarting the steam generator, or other components that do not affect the operation of the steam generator may be problematic. However, when the steam generator is in the failure state several times, it may be determined that the steam generator may be in the failure state really, and related maintenance may be required, and thus alarm information may need to be output.
