Technical field

The present invention relates to the technical field of dishwashers, and specifically to a filter assembly and a dishwasher.

Background technique

At present, when using existing dishwashers, users often need to remove the filter for cleaning to ensure better cleaning effect. However, when the filter is installed inside the dishwasher, in order to ensure the cleaning effect, the filter is often removed. The filter snaps in, but unfamiliar users often only put the filter into the dishwasher when using it, without knowing whether it is installed in place. As a result, when the dishwasher is started again, the tableware cannot be cleaned, which is a huge problem. Affect user experience.

Contents of the invention

The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

In view of this, an embodiment of a first aspect of the present invention provides a filter assembly.

An embodiment of the second aspect of the invention provides a dishwasher.

In order to achieve the above object, an embodiment of the first aspect of the present invention provides a filter assembly, including: a water cup, a first detection member is provided on the water cup; a filter member is detachably connected to the water cup, the filter member is disposed in the water cup, and the filter member is disposed in the water cup. The component is provided with a second detection component; a controller is electrically connected to the first detection component and the second detection component, and the controller is used to determine the detection information sent by the first detection component and/or the second detection component, and determine based on the detection information Whether the filter is installed in place relative to the water cup.

A filter assembly provided according to an embodiment of the first aspect of the present invention mainly includes a water cup, a filter element and a controller. The water cup is used to carry fluid for cleaning tableware, and the filter element is used to filter food residues in the fluid to prevent It flows out along the water pipe and accumulates at the corners, which not only affects the normal use, but also reduces the possible damage to the pipeline caused by the harder residue. It can be understood that the fluid component can be a mixture of detergent and water, and the sewage is formed after the dishes are washed. Specifically, when the filter is dismantled, it often happens that the installation is not in place, so that the filter cannot filter the sewage normally. In order to ensure that the filter is installed in place, this solution has an additional first detection part and a second detection part. components, wherein the first detection component is disposed on the water cup, and the second detection component is disposed on the filter component. A part of the filter component or the entire filter component is located in the water cup during use and can be removed from the water cup for easy replacement. Or cleaning, and by setting two detection parts, the position of the filter part relative to the water cup can be detected, that is, whether the filter part is installed in place can be detected. It should be noted that when the filter element is installed in the water cup, its position is fixed. However, in order to improve the tightness of the filter element in the water cup and ensure the filtration efficiency, it will be stuck and will not come off easily. Therefore, by setting up a controller, it can be electrically connected to the two detection parts, so that when the detection part sends out detection information, the controller can obtain it in time, so as to further determine the relative position of the filter element and the water cup based on the detection information, so as to judge Whether the filter is installed in place to ensure the cleaning effect when the tableware is subsequently cleaned.

It should be added that the position of the filter element relative to the water cup includes but is not limited to axial position, radial position, circumferential position and other multi-dimensional position relationships.

Among them, the filter elements include, but are not limited to, structures such as cups, cylindrical filters, and flat filters.

Among them, the detection information can be selectively sent out through the first detection piece, and can also be sent out through the second detection piece, or even the first detection piece and the second detection piece can be combined to send out the information together.

In the above technical solution, one of the first detection member and the second detection member is a sensor, and the other is a trigger. The sensor is used to send out a digital signal, and the controller is used to determine whether the filter member is installed in place relative to the water cup based on the digital signal.

In this technical solution, the two detection parts are a sensor and a trigger respectively. The sensor can send out different digital signals according to the position of the trigger, so that the controller can judge the relative relationship between the trigger and the sensor based on the digital signal. position, which facilitates the determination of the position of the filter element.

Specifically, when the position of the filter relative to the water cup changes, the corresponding signal value will change every time it changes to a position, so that when the controller obtains different signal values, it can judge the relative position.

Alternatively, after the filter is installed in place, the corresponding signal value will change directly, so that the digital signal can be used to determine whether the filter is installed in place.

In the above technical solution, the first detection component is a Hall sensor, and the second detection component is a magnetic component. The Hall sensor sends detection information. When the filter component and the water cup are installed in place, the Hall sensor determines that the magnetic field intensity generated by the magnetic component is the largest.

When the filter is installed on the water cup, the moving charges are subject to the Lorentz force in the magnetic field, causing the current to deviate to one side when passing through the Hall sensor, resulting in a potential difference in the vertical direction of the current. By analyzing the strength, when the Hall sensor determines that the magnetic component generates the maximum magnetic field intensity, it can determine that the current position of the filter is the installed position, that is, determine whether it is installed in place.
