At this time, the user's recognition of home appliances directly determines the user's purchase target for replacing home appliances.

[0003] At present, most dishwashers choose to wash in the lower partition. When the lower rack is fully loaded, the lower sprayer cannot rinse the dishwashing powder in the detergent dispenser, which easily causes dishwashing powder residue and causes dishes to be washed uncleanly. In addition, users can only put dishwashing powder into the inner tank, and the pre-wash function cannot be realized.

[0004] The Chinese patent application number 201510742463.X discloses a dishwasher sprayer, which includes a horizontally arranged spray arm, and the spray arm is provided with at least one spray hole; the spray arm is directly or through a transmission mechanism meshingly connected to the motor, and the spray arm rotates or swings in a horizontal plane under the drive of the motor. The present invention also introduces a dishwasher equipped with the above-mentioned sprayer and a control method, wherein the spray arm is driven by the motor to reciprocate within a certain rotation angle so that the sprayed water radiates to all or part of the area in the dishwasher to wash the items placed in the area. Thereby, the spray water flow does not need to be used to drive the spray arm to rotate, but is entirely used to wash the items, so as to reduce the water consumption; at the same time, the spray arm is reciprocated in a specific area to achieve the purpose of enhanced washing or specific washing of the specific area, so as to achieve the purpose of improving the washing efficiency of the dishwasher.

[0005] The spray arm of the dishwasher sprayer swings back and forth so that the sprayed water radiates to the area inside the dishwasher for washing. However, this washing method still cannot solve the problem that the lower sprayer cannot rinse the dishwashing powder when the dishwasher is fully loaded, resulting in poor tableware washing effect.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a control method for a dishwasher and a dishwasher. When the dishwasher receives an instruction to wash the lower partition, the sprayer is controlled to rinse the dishwashing powder in the detergent adder, so that the dishwashing powder dissolves quickly, which is beneficial to the cleaning of the tableware.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In existing dishwashers, when the lower partition is selected for washing, dishwashing powder or dishwashing cubes can only be put directly into the inner tank, and cannot be placed in the detergent dispenser; or when the lower rack is fully loaded, the lower sprayer cannot directly rinse the dishwashing powder in the detergent dispenser, resulting in the dishes not being washed clean.

[0036] Embodiment 1

[0037] To solve the above technical problems, Figures 1 to 3 As shown, this embodiment provides a method for controlling a dishwasher, comprising:

[0038] Upon receiving the instruction to wash the lower partition, the middle sprayer is controlled to rinse the dishwashing powder in the detergent dispenser according to a predetermined spraying program. In this embodiment, the dishwasher further includes a middle sprayer, which is used to rinse the washed dishes in the detergent dispenser and can also be used to rinse the tableware on the lower partition shelf.

[0039] Specifically, when the dishwasher receives an instruction to wash the next partition, the sprayer is controlled to rinse the dishwashing powder in the detergent adder, so that the dishwashing powder dissolves quickly, which is beneficial to the cleaning of the tableware.

[0040] In the above solution, the dishwasher is provided with a lower partition, and the washing area of ​​the dishwasher is partitioned, which effectively improves the washing efficiency of the dishwasher and improves the washing effect of the dishwasher on tableware.

[0041] The dishwasher comprises a lower sprayer, which is arranged in the lower partition. The water flow sprayed by the lower sprayer rinses the tableware on the rack of the lower partition to achieve the effect of washing the tableware.

[0042] In the implementation process, when the user needs to wash the dishes, he selects the lower partition washing program. When the dishwasher receives the lower partition washing instruction issued by the user, the dishwasher actively controls the lower sprayer to execute the water spraying program, that is, the dishwasher controls the lower sprayer to wash the dishes in the lower partition.

[0043] In a further solution of this embodiment, before the middle sprayer performs the spraying procedure, the method includes: detecting an open state of a cover of the detergent adder.

[0044] In this embodiment, the dishwasher further comprises a detergent adder, in which dishwashing powder is placed. The middle sprayer can rinse the dishwashing powder in the detergent adder to achieve the dissolution process of the dishwashing powder.

[0045] Further, if it is detected that the cover of the detergent adder is in an open state, the sprayer is controlled to perform a spraying program.

[0046] Specifically, if it is detected that the lid of the detergent dispenser of the dishwasher is in an open state, that is, the dishwashing powder in the detergent dispenser needs to be rinsed, the sprayer in the control unit executes a water spraying program to rinse the dishwashing powder in the detergent dispenser to dissolve the dishwashing powder.

[0047] If it is detected that the lid of the detergent adder is in the closed state, the sprayer is controlled to suspend the spraying program.

[0048] Specifically, if it is detected that the lid of the detergent dispenser is in a closed state, it means that the dishes do not need to be processed at present, and the dishwashing powder in the detergent dispenser does not need to be rinsed, thereby realizing intelligent control of the rinsing of the dishwashing powder.

[0049] In this embodiment, a temperature sensor is provided in the dishwasher, which is used to detect the temperature of the water flow sprayed by the lower sprayer, so as to accelerate the dissolution speed of the dishwashing powder and improve the rinsing efficiency of the dishwasher.

[0050] In a further solution of this embodiment, before the middle sprayer executes the spraying procedure, the process includes: controlling the temperature of the water flow to increase.

[0051] Specifically, before the middle sprayer executes the spraying program, the water temperature in the dishwasher is increased so that the high-temperature water sprayed by the middle sprayer can quickly dissolve the dishwashing powder, thereby accelerating the dissolution rate of the dishwashing powder and improving the washing effect on the tableware.

[0052] Further, when the detected water flow temperature reaches a preset temperature, the middle sprayer and the lower sprayer are controlled to jointly perform a spraying procedure.

[0053] The preset temperature mentioned here can be understood as when the temperature of the water sprayed by the lower sprayer reaches a certain value, the dishwasher executes another water spraying program.

[0054] Specifically, when the dishwasher detects that the temperature of the water sprayed from the lower sprayer reaches a preset temperature, it actively controls the lower sprayer and the middle sprayer to execute the water spraying program, that is, controls the lower sprayer and the middle sprayer to jointly rinse the tableware on the lower partition shelf to achieve the purpose of washing the tableware, thereby effectively shortening the washing time of the tableware and improving the washing effect of the dishwasher on the tableware.

[0055] In this embodiment, the preset temperature can be adaptively adjusted according to actual usage requirements, which will not be elaborated here.

[0056] As described above, when the water temperature sprayed from the lower sprayer reaches the preset temperature, the lower sprayer and the middle sprayer are controlled to rinse the tableware on the lower partition shelf together, so that the higher water temperature can easily dissolve the dishwashing powder, effectively improving the washing effect and efficiency of the tableware.

[0057] In a further solution of this embodiment, the dishwasher is provided with a water diversion valve.

[0058] Specifically, the dishwasher further includes a water diverter valve, which is used to adjust the direction of water flow. When the water diverter valve is rotated to a certain angle, the lower sprayer is connected to start spraying water; when the water diverter valve continues to rotate to another angle, the lower sprayer and the middle sprayer are connected together to spray water. By setting the water diverter valve and adjusting its rotation angle to control the water spraying process of the lower sprayer or the middle sprayer, it is convenient to realize the intelligent selection of the water spraying program of the dishwasher, thereby improving the intelligence level of the dishwasher.

[0059] Furthermore, receiving the instruction for washing the lower partition includes: controlling the rotation angle of the water diversion valve to reach a first preset angle, and controlling the lower sprayer to execute a spraying program.

[0060] Specifically, when the dishwasher receives a lower partition washing instruction from the user, it starts to control the water diversion valve of the dishwasher to operate, and then controls and adjusts the rotation angle of the water diversion valve to reach a first preset angle, that is, controls the rotation angle of the water diversion valve to a certain value. At this time, the lower sprayer is controlled to spray water, and the water flow sprayed by the lower sprayer washes the tableware on the lower partition shelf, thereby realizing the process of washing the tableware.

[0061] In this embodiment, the first preset angle can be adaptively adjusted according to actual usage requirements, which will not be elaborated here.

[0062] In a further scheme of this embodiment, when the dishwasher receives an instruction from the user to wash the lower zone, it starts to control the water diversion valve of the dishwasher to operate, and then controls and adjusts the rotation angle of the water diversion valve to reach a first preset angle. At this time, the lower sprayer is controlled to spray water, and at the same time, the water temperature of the lower sprayer is controlled to increase, so that the higher temperature water flow sprayed by the lower sprayer rinses the dishwashing powder, effectively accelerating the dissolution rate of the dishwashing powder, and the high-temperature water flow also helps the dishwashing powder to dissolve and clean stains on the tableware, thereby improving the washing effect of the dishwasher.

[0063] In a further solution of this embodiment, the water diversion valve is controlled to move again, and the rotation angle of the water diversion valve is adjusted to reach a second preset angle.

[0064] The second preset angle mentioned here can be understood as the rotation angle of the water diversion valve reaching a certain value, at which time the lower sprinkler and the middle sprinkler are controlled to execute the water spraying program.

[0065] Specifically, when the lower sprayer of the dishwasher starts to execute the water spraying program and the water temperature of the lower sprayer is increased, if it is detected that the water temperature sprayed by the lower sprayer reaches a preset temperature, the water diversion valve of the dishwasher is controlled to operate again, so that the rotation angle of the water diversion valve is adjusted to a second preset angle, and the lower sprayer and the middle sprayer are controlled to execute the water spraying program together, thereby further improving the washing efficiency of the dishwasher.

[0066] Furthermore, after the rotation angle of the water diversion valve reaches a second preset angle, the lower sprayer and the middle sprayer are controlled to spray water.

[0067] Specifically, when the dishwasher detects that the water temperature of the lower sprayer reaches a preset temperature, the water diversion valve of the dishwasher is controlled to continue to rotate to a second preset angle, and the lower sprayer and the middle sprayer are controlled to act in combination to rinse the tableware in the lower partition. At the same time, the middle sprayer can rinse the detergent powder in the detergent adder to accelerate the dissolution of the detergent powder, thereby further improving the washing effect of the dishwasher.

[0068] In this embodiment, the second preset angle can be adaptively adjusted according to specific usage requirements, which will not be elaborated here.

[0069] Furthermore, the second preset angle is greater than the first preset angle.

[0070] Specifically, when the dishwasher receives the instruction to wash the lower partition, the water diversion valve is controlled to rotate to the first preset angle, thereby controlling the lower sprayer to rinse. When the dishwasher detects that the current water temperature reaches the preset temperature, the water diversion valve is controlled to continue to rotate to the second preset angle, thereby controlling the lower sprayer and the middle sprayer to act in combination. It can be seen that by setting the second preset angle to be greater than the first preset angle, the working process of the water diversion valve controlling the lower sprayer and the middle sprayer can be realized.

[0071] Further, when the duration of the lower sprinkler and the middle sprinkler spraying water together reaches a preset time, the lower sprinkler is controlled to continue spraying water.

[0072] The preset time mentioned here can be understood as the duration of the lower sprayer and the middle sprayer working together.

[0073] In this embodiment, the preset time may be 3 minutes. The preset time may be adaptively adjusted according to specific usage requirements, which will not be described in detail here.

[0074] Specifically, when the dishwasher detects that the current water temperature reaches the preset temperature, the lower sprayer and the middle sprayer are controlled to work together to rinse the tableware on the lower partition shelf. When the working time of the lower sprayer and the middle sprayer reaches the preset time, the middle sprayer can be controlled to stop working, and the lower sprayer continues to execute the water spraying program. In this way, after the middle sprayer finishes rinsing the dishwashing powder in the detergent adder, the middle sprayer and the lower sprayer rinse the tableware together, effectively improving the cleaning efficiency of the tableware, and setting the middle sprayer to stop running after rinsing for a period of time can effectively save the water consumption of the dishwasher and avoid wasting resources of the dishwasher.

[0075] In another solution of this embodiment, when it is detected that the residual amount of dishwashing powder in the detergent adder reaches a preset amount, the middle sprayer is controlled to stop running and the lower sprayer continues to perform the spraying program.

[0076] The preset amount mentioned here can be understood as when the residual amount of dishwashing powder reaches a certain value, the sprinkler in the control stops spraying water.

[0077] Specifically, when it is detected that the residual amount of dishwashing powder in the detergent dispenser reaches a preset amount, that is, the dishwashing powder is completely dissolved, and there is no need to continue rinsing the detergent dispenser, the middle sprayer is controlled to stop running, and the lower sprayer continues to execute the spraying program to ensure normal washing of the dishes.

[0078] Embodiment 2

[0079] This embodiment is a further description of the above embodiment 1.

[0080] This embodiment also provides a dishwasher, to which the above-mentioned control method of the dishwasher is applied.

[0081] In this embodiment, the dishwasher comprises a middle sprayer, a lower sprayer and a water diversion valve. The middle sprayer sprays a rotating water flow. The water diversion valve can be used to adjust the working states of the lower sprayer and the middle sprayer.

[0082] Specifically, when the user selects the lower partition washing program, the water diversion valve of the dishwasher rotates to a certain angle, so that the lower sprayer sprays water for washing. When the temperature of the water sprayed by the lower sprayer reaches a preset temperature, the water diversion valve is controlled to continue to rotate to another angle, so that the lower sprayer and the middle sprayer work together to wash the tableware in the lower partition.

[0083] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as above in preferred embodiments, they are not intended to limit the present invention.
