[0029] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.
[0030] The method for removing odor from a dishwasher provided by the embodiments of the present application can be applied to a smart dishwasher. As shown in FIGS. 1a, 1b and 1c, the smart dishwasher comprises an odor sensor 110, a master control device 120, a clean discharge pump 130, a supply air fan 140, an exhaust air fan 150 and a heater 160. The odor sensor 110 is arranged inside the smart dishwasher and is used to collect the odor concentration in the smart dishwasher when the smart dishwasher is in a non-washing state. The clean discharge pump 130 is arranged below a filter cup in the smart dishwasher. The supply air fan 140 and the exhaust air fan 150 are arranged on two side walls of the smart dishwasher respectively. The heater 160 is arranged at a pipeline of the supply air fan 140. The master control device 120 is arranged inside the smart dishwasher and is used to control the clean discharge pump 130 to discharge sewage in the smart dishwasher and control the supply air fan 140 and the exhaust air fan 150 to discharge odor in the smart dishwasher. The master control device 120 is also used to start the heater 160 so that the supply air fan outputs hot air to sterilize the smart dishwasher. Figure 1a 1b The method for removing odor from a dishwasher provided by the embodiments of the present application will be described in detail below with reference to the specific embodiments. As shown in FIG. 1a, the specific steps are as follows.
[0031] The method for removing odor from a dishwasher provided by the embodiments of the present application will be described in detail below with reference to the specific embodiments. As shown in FIG. 1a, the specific steps are as follows. Figure 2
[0032] Step 201: When the smart dishwasher is in a non-washing state, the odor concentration in the smart dishwasher is collected by the odor sensor.
[0033] In implementation, when the smart dishwasher is in a non-washing state, the dishes, the inner wall of the smart dishwasher and the filter cup may all be left with sewage, which may generate odor in the closed environment of the smart dishwasher. The smart dishwasher collects the odor concentration in the smart dishwasher by the internal odor sensor.
[0034] Step 202: If the collected odor concentration is greater than or equal to a first odor threshold, the sewage in the smart dishwasher is discharged by the clean discharge pump and the odor in the smart dishwasher is discharged by the supply air fan and the exhaust air fan.
[0035] In the implementation, if the odor concentration collected by the odor sensor is greater than or equal to the first odor threshold value, it indicates that the odor concentration is high at this time, and the source of the odor, i.e. the sewage, must be cleaned first. Therefore, the intelligent dishwasher preliminarily discharges the sewage in the intelligent dishwasher through the clean discharge pump (there may be a case that it cannot be completely discharged at one time), and then the intelligent dishwasher starts the air supply fan and the air exhaust fan to exchange the fresh air outside the intelligent dishwasher with the mixed odor air inside the intelligent dishwasher, so as to achieve the purpose of discharging the odor in the intelligent dishwasher.
[0036] In step 203, in the process of discharging the odor in the intelligent dishwasher, if the collected odor concentration is less than or equal to the second odor threshold value, the heater is started to make the air supply fan output hot air to sterilize the intelligent dishwasher.
[0037] In the implementation, in the process of discharging the odor in the intelligent dishwasher by starting the air supply fan and the air exhaust fan, if the odor concentration collected by the odor sensor is less than or equal to the second odor threshold value, it indicates that the odor value in the intelligent dishwasher has been reduced. The intelligent dishwasher can start the heater to heat the air supplied into the intelligent dishwasher by the air supply fan, and use the high-temperature air to sterilize the inside of the intelligent dishwasher.
[0038] In step 204, in the process of sterilizing the intelligent dishwasher, if the collected odor concentration is less than or equal to the third odor threshold value, the sewage in the intelligent dishwasher is discharged through the clean discharge pump, and the air supply fan, the air exhaust fan and the heater are stopped.
[0039] In the implementation, in the process of heating sterilization of the intelligent dishwasher, if the odor concentration collected by the odor sensor is less than or equal to the third odor threshold value, it indicates that the odor concentration in the intelligent dishwasher has been reduced to the odorless level. At this time, the intelligent dishwasher discharges the sewage in the intelligent dishwasher again through the clean discharge pump (the sewage is discharged twice to ensure that the sewage is completely discharged), and then the intelligent dishwasher stops the air supply fan, the air exhaust fan and the heater from working, and the intelligent dishwasher completes a sterilization and odor removal cycle.
[0040] As an optional implementation, in the process of discharging the odor in the intelligent dishwasher, if the collected odor concentration is greater than the second odor threshold value, the step of discharging the odor in the intelligent dishwasher through the air supply fan and the air exhaust fan in step 202 is performed.
[0041] In the implementation, in the process of discharging the odor in the intelligent dishwasher by starting the air supply fan and the air exhaust fan, if the odor concentration collected by the odor sensor is greater than the second odor threshold value, it indicates that the odor concentration in the intelligent dishwasher is still high at this time, and the intelligent dishwasher continues to discharge the odor in the intelligent dishwasher through the air supply fan and the air exhaust fan.
[0042] As an optional implementation, in the process of sterilizing the intelligent dishwasher, if the collected odor concentration is greater than the third odor threshold, the step of discharging the odor in the intelligent dishwasher by the air supply fan and the air exhaust fan in step 202 is performed.
[0043] In implementation, in the process of sterilizing the intelligent dishwasher, if the odor concentration collected by the odor sensor is greater than the third odor threshold, it indicates that the odor concentration in the intelligent dishwasher at this time does not reach the odorless level, and the deodorization and sterilization work still needs to be performed.
[0044] Optionally, the setting of the first odor threshold, the second odor threshold and the third odor threshold can refer to the odor intensity level and the relationship between gas concentration and odor intensity level. As shown in Table 1:
[0045] Table 1
[0046] 0 grade 1 grade 2 grade 3 grade 4 grade 5 grade No odor Detection threshold Cognition threshold Obvious detection Strong odor Very strong odor
[0047] For example: ammonia concentration of 1 ppm is defined as level 2.5, 2 ppm is defined as level 3, and 5 ppm is defined as level 3.5. The odor level of various odors exceeding 2.5-3.5 levels is considered to be contaminated by odor, and measures need to be taken to prevent and control.
[0048] As an optional implementation, the specific steps of discharging the sewage in the intelligent dishwasher by the clean discharge pump are to discharge the sewage in the intelligent dishwasher by the clean discharge pump according to the preset drainage time.
[0049] In implementation, the intelligent dishwasher discharges the sewage in the intelligent dishwasher by the clean discharge pump according to the preset drainage time. The setting of the drainage time is based on the relationship between the water quantity and the drainage capacity of the drainage pump.
[0050] Figure 3 A flowchart of an example of a dishwasher deodorization method provided by the embodiments of the present application is shown in FIG. 3, and the specific processing process is as follows:
[0051] Step 301: Collect the odor concentration in the intelligent dishwasher by the odor sensor.
[0052] Step 302: Determine whether the collected odor concentration is greater than or equal to the first odor threshold.
[0053] If the collected odor concentration is greater than or equal to the first odor threshold, step 303 is performed, and if the collected odor concentration is less than the first odor threshold, step 301 is performed.
[0054] Step 303: Discharge the sewage in the intelligent dishwasher by the clean discharge pump.
[0055] Step 304: Discharge the odor in the intelligent dishwasher by the air supply fan and the air exhaust fan.
[0056] Step 305, judge whether the collected odor concentration is less than or equal to the second odor threshold value.
[0057] If the collected odor concentration is less than or equal to the second odor threshold value, step 306 is executed, and if the collected odor concentration is greater than the second odor threshold value, step 304 is executed.
[0058] Step 306, start the heater to make the air supply fan output hot air to sterilize the intelligent dishwasher.
[0059] Step 307, judge whether the collected odor concentration is less than or equal to the third odor threshold value.
[0060] If the collected odor concentration is less than or equal to the third odor threshold value, step 308 is executed, and if the collected odor concentration is greater than the third odor threshold value, step 304 is executed.
[0061] Step 308, discharge the sewage in the intelligent dishwasher through the clean discharge pump, and stop the air supply fan, the air exhaust fan and the heater.
[0062] The embodiment of the present application provides a dishwasher odor removal method. When the intelligent dishwasher is in a non-washing state, an odor sensor is used to collect the odor concentration in the intelligent dishwasher. If the collected odor concentration is greater than or equal to the first odor threshold value, the sewage in the intelligent dishwasher is discharged through a clean discharge pump, and the odor in the intelligent dishwasher is discharged through an air supply fan and an air exhaust fan. During the process of discharging the odor in the intelligent dishwasher, if the collected odor concentration is less than or equal to the second odor threshold value, the heater is started to make the air supply fan output hot air to sterilize the intelligent dishwasher. During the process of sterilizing the intelligent dishwasher, if the collected odor concentration is less than or equal to the third odor threshold value, the sewage in the intelligent dishwasher is discharged through the clean discharge pump, and the air supply fan, the air exhaust fan and the heater are stopped. The present application can timely clean the sewage according to the odor concentration, prevent the sewage from being stored for too long to cause odor and bacteria, and avoid the pollution of the stored tableware in the intelligent dishwasher.
