In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

It should be noted that the steps shown in the flowcharts of the accompanying drawings may be performed in a computer system, such as a set of computer-executable instructions, and that although a logical order is shown in the flowcharts, in some cases, The steps shown or described may be performed in an order different than here.

Example 1

Embodiment 1 of the present invention provides a control method for a dishwasher. FIG. 1 is a schematic flowchart of the control method for a dishwasher in Embodiment 1 of the present invention. FIG. 2 is a structure of the rinsing part of the dishwasher in Embodiment 1 of the present invention. schematic diagram. As shown in Figure 1, the dishwasher control method according to Embodiment 1 of the present invention includes the following steps:

S101: After the penultimate rinse of the dishwasher ends and before the penultimate rinse of the dishwasher starts, acquire the current amount of rinse aid in the rinse aid storage device.

Exemplarily, the current amount may be the current weight of the rinse agent, and may also be the current volume of the rinse agent.

Specifically, a weight sensor can be set in the rinse agent storage device such as the rinse agent storage tank, and the current weight of the rinse agent in the rinse agent storage tank can be obtained through the weight sensor; The picture of gets the current volume of rinse aid in the rinse aid storage tank.

S102: When the current amount of the rinsing agent is less than the preset first threshold value, perform the penultimate rinsing by using the preset first rinsing temperature, wherein the first rinsing temperature is lower than the second rinsing temperature, so The second rinsing temperature is the maximum temperature of the water in the inner container when the penultimate rinsing is performed when the current amount of the rinsing agent is greater than the first threshold.

As shown in Figure 2, the water inlet device, drain pump, heating device, washing pump and soft water device are connected with the controller. When rinsing is required, the controller controls the water inlet device so that the water passes into the inner tank of the dishwasher. Before the water enters the inner tank, the controller controls the heating device to heat the water. In addition, the controller can control the water softening device Soften the water; after the water enters the inner container, the controller controls the washing pump to rinse, and after rinsing, the water in the inner container is discharged by the drain pump. In addition, the blower fan, the PTC heating body and the rinse dosage acquisition device are also connected with the controller.

Specifically, the penultimate rinsing by using the preset first rinsing temperature can adopt the following scheme: control the water entering the inner tank; use the preset heating device to control the water entering the inner tank heating; obtaining the actual temperature of the water in the inner tank; when the actual temperature reaches the first rinsing temperature, controlling the heating device so that the actual temperature of the water in the inner tank is maintained at the first The first heating time preset for the rinse temperature.

Specifically, the penultimate rinsing by using the preset second rinsing temperature can adopt the following scheme: control the water entering the inner tank; use the preset heating device to control the water entering the inner tank heating; obtaining the actual temperature of the water in the inner container; when the actual temperature reaches the second rinsing temperature, controlling the heating device so that the actual temperature of the water in the inner container is maintained at the second The second heating time preset at the rinse temperature.

In the control method of the above-mentioned dishwasher, after the penultimate rinse of the dishwasher is completed and before the penultimate rinse of the dishwasher is started, the current amount of rinse agent in the rinse agent storage device can be determined, so that the rinse can be judged. Whether the current amount of rinse aid is sufficient, that is, whether the current amount of rinse aid is sufficient for the penultimate rinse. When the current amount is greater than the first threshold, it can be considered that the amount of rinse agent in the rinse agent storage device is sufficient at this time, so that a sufficient amount of rinse agent can be used when performing the penultimate rinse, this situation is called normal Rinsing; when the current amount is less than or equal to the first threshold, it can be considered that the amount of rinse agent in the rinse agent storage device is insufficient at this time, so that the rinse agent cannot be used or the amount of rinse agent is insufficient when performing the penultimate rinse, This situation is called abnormal rinsing, and can also be called compensation rinsing. When rinsing agent cannot be used or the amount of rinsing agent is insufficient during the penultimate rinsing, by lowering the rinsing temperature during the penultimate rinsing, the generation of limescale can be reduced and water marks on the tableware surface can be avoided.

This is because, in order to improve the drying effect and reduce water marks, when the penultimate rinse is a normal rinse, that is, when the rinse agent is sufficient for the penultimate rinse, it is usually necessary to set a higher rinse temperature, that is, the second rinse temperature higher. Exemplarily, the second rinsing temperature is 70-75°C. This is because the main component of dishwasher rinse aid contains citric acid, which makes its solution slightly acidic; currently on the market, citric acid is used as a component of descaling agents. The reaction of the ingredients calcium carbonate/magnesium hydroxide produces soluble salts, which will not remain on the surface of the tableware, so there will be no limescale and water marks.

However, when the last-to-last rinse is an abnormal rinse, that is, when the rinse agent is not enough for the last-to-last rinse, the second-to-last rinse is still used because there is no rinse agent or insufficient rinse agent is used. Rinsing at a higher rinse temperature may produce limescale, which further leads to the possibility of water marks on the dishes after rinsing. In the control method of the dishwasher in Example 1 of the present invention, when the rinse agent cannot be used or the amount of the rinse agent is insufficient during the last-to-last rinse, the rinsing temperature during the last-to-last rinse can be reduced. Scale formation, to avoid water marks on the surface of the tableware. Exemplarily, the first rinsing temperature may be 45-55°C.

Wherein, different dishwashers may set different first thresholds.

As a first further specific implementation manner, when the fan is not turned on before performing the penultimate rinsing, when performing the penultimate rinsing at the first rinsing temperature, it also includes turning on the fan. As a result, the air convection in the inner container of the dishwasher can be accelerated by turning on the blower during the last rinsing, so that the moisture in the inner container can be quickly discharged, and the drying of the tableware can be accelerated.

This is because, since the first rinsing temperature is lower than the second rinsing temperature, when using the first rinsing temperature for the last rinsing, the drying time will be longer; at this time, by turning on the fan, the liner can be quickly discharged Moisture in the oven accelerates the drying of dishes.

As a second further specific implementation manner, when the blower is turned on before performing the penultimate rinsing, before performing the penultimate rinsing at the first rinsing temperature, it further includes: acquiring The current rotational speed of the fan; determining the actual rotational speed of the fan when performing the last-to-last rinsing according to the current rotational speed, wherein the actual rotational speed is greater than the current rotational speed. When performing the penultimate rinsing at the first rinsing temperature, the method further includes: controlling the fan to rotate at the actual rotational speed. In this way, during the penultimate rinsing, the air convection in the inner tank of the dishwasher can be accelerated by increasing the speed of the fan, so that the moisture in the inner tank can be quickly discharged, and the drying of the tableware can be accelerated. As an example, the fan speed can be increased by 500-2000rpm.

As a third further implementation manner, when the PTC heating element is not turned on before performing the penultimate rinsing, when performing the penultimate rinsing at the first rinsing temperature, it also includes: turning on The PTC heating element. As a result, the PTC heating element can be turned on during the penultimate rinsing, so that the airflow in the inner tank can accommodate more saturated water vapor, thereby accelerating the drying of the tableware in the dishwasher, further improving the drying efficiency, and realizing Better drying of dishes. For example, the time to turn on the PTC heating element is 10-30 minutes.

That is to say, in Embodiment 1 of the present invention, the compensation rinsing can adopt the following methods:

Mode 1 is: using the first rinsing temperature to perform the penultimate rinsing may be called compensation rinsing;

The second way is: use the first rinsing temperature to perform the last rinsing for the first time, and at the same time turn on the fan or increase the fan speed;

The third method is: use the first rinsing temperature to perform the first last rinsing, and at the same time turn on the PTC heating body;

The fourth way is: use the first rinsing temperature to perform the first last rinsing, and at the same time turn on the fan and turn on the PTC heating body;

The fifth way is: use the first rinsing temperature to perform the last-to-last rinsing, increase the fan speed and turn on the PTC heating element at the same time.

As a fourth further implementation, after the control water for compensating rinsing enters the inner tank of the dishwasher, the following method is also included: continue to obtain the current amount of rinse agent in the rinse agent storage device; when the current amount When the first threshold value is greater than or equal to the first threshold, the washing parameters are obtained, and it is judged according to the washing parameters whether the rinse agent meets the preset delivery conditions; when the rinse agent meets the delivery conditions, the second rinsing temperature is used performing the penultimate rinsing; when the rinsing agent does not meet the delivery conditions, using the first rinsing temperature to perform the penultimate rinsing. That is to say, during the penultimate rinsing process, when the user adds rinse agent to the rinse agent dispensing device, the rinse agent in the rinse agent dispensing device is sufficient for the penultimate rinse, and at this time it is necessary to determine the amount of rinse agent Whether it can be put into the inner tank, when it can be put into the inner tank, because there is a rinse agent in the inner tank, it can be rinsed normally, that is, the penultimate rinse can be performed using the second rinsing temperature; When pouring into the liner, a make-up rinse is still required since there is no rinse agent in the liner.

It should be noted that when the penultimate rinsing is performed at the second rinsing temperature, since the temperature of the water is higher, the drying effect is better, and the fan and/or the PTC heating body may not be turned on at this time.

Wherein, the washing parameter is the actual temperature of the water in the liner during the penultimate rinsing. Specifically, the following method may be used to determine whether the rinse agent meets the preset delivery condition according to the washing parameters: when the actual temperature is lower than the preset second threshold value, it is determined that the rinse agent meets the delivery condition ; When the actual temperature is greater than or equal to the second threshold, it is determined that the rinse agent does not meet the delivery condition.

To sum up, the control method of the dishwasher provided by Embodiment 1 of the present invention has the following beneficial effects: when it is detected that there is no rinse agent or the amount of rinse agent is insufficient in the rinse agent delivery device, the mechanism for compensating the effect of the rinse agent is automatically activated; When a user replenishment of rinse aid is detected, this compensation mechanism is exited and the use of rinse aid resumes. This prevents water marks on the surface of the tableware.
