Description

The invention relates to devices designed for washing dishes and allows washing both in manual and semi-automatic mode.

The dimensions of the premises in apartments and houses often do not allow arranging the necessary amount of household appliances necessary for the comfortable existence of the family. One type of household appliance that has to be abandoned in favor of saving space is dishwashers, which complement the kitchen sink in the premises.

The solution I propose combines a sink and a dishwasher in one device, thus ensuring the preservation of kitchen space and ensuring a comfortable life even in cramped conditions.

The prior art patent JP 2007061555 describes a sink with a dishwasher, while the dishwasher is located under the sink and is a separate structure having a common bedside table with the sink.

The differences from the claimed solution are that:

- Sink with built-in dishwasher combines sink elements and dishwasher elements in a single device.

- In the claimed invention, the shell has an original design with the possibility of rotation around the axis.

Known patent JP 2012192106, describing a sink with a dishwasher, while in the sink compartment there are elements of the dishwasher, and the sink compartment can be divided by a partition to ensure the operation of the dishwasher.

The differences from the claimed solution are that:

- A sink with a built-in dishwasher uses the same amount of space for manual and semi-automatic or automatic washing.

- The claimed solution provides for the possibility of rotation of the dishwashing compartment around the axis.

Known patent JP 2005137825, describing a sink with a built-in dishwasher, which uses a separate insert, and water is supplied from different sides through the holes in the body of the sink.

The differences from the claimed solution are that:

- A sink with a built-in dishwasher uses a special lid with holes, or is used without a lid with filling the sink compartment with tap water.

- The claimed solution provides for the possibility of rotation of the dishwashing compartment around the axis.

The technical result of the claimed invention consists in the development of a device that combines a sink compartment and elements that provide automatic washing of dishes without the need to occupy additional space next to the sink.

The technical result is achieved by creating a shell compartment with holes, which is placed inside the shell body, on which devices for creating a water flow (water movement) and water flow guides are placed.

Particular cases of manufacturing a structure are:

- Changing the size of the structure;

- Changing the shape of the structure.

Washing dishes in the sink is possible using a manual method, semi-automatic and automatic. In general, a semi-automatic method is used.

A sink with a built-in dishwasher works as follows:

In the case of a complete set of parts similar to those indicated in the images (options in which the parts differ from those shown are indicated in the design features section), water 18 enters the internal cavity of the cover 3 through a tap 4 using a hose 17. Further, through a plurality of holes in the inner wall 16 of the cover 3, water 18 randomly enters the sink compartment 2, merging onto the dishes located there. When the required water level is set (determined by sensors, indicators, visually, or by time), the tap 4 is closed and the water stops flowing into the sink compartment 2. Moreover, water fills not only the internal compartment of the sink 2, the walls of which have holes, but also base interior 1.

Further, automatically from the command of sensors or by human actions, the electric motor 11 is turned on, from which the axis 10 is driven into rotation with the activator 5 installed on it, which also begins to rotate together with the axis, exciting the movement of water inside the base 1 and, accordingly, inside the sink compartment 2, since it made with holes and/or mesh, including partially, which allows the water 18 located inside the compartment of the sink 2 also to move. The activator 5 mainly ensures the movement of water in the form of a whirlpool, while the water tends to collect at the walls of the base 1 with a decrease in the level inside the compartment of the sink 2. To avoid this and create chaotic splashes that will randomly fall through the openings of the compartment 2 onto the dishes in the compartment, flow guides 14 are used, which are installed on the walls of the base 1 and have a shape that allows you to redirect the flow of water 18 towards the sink compartment 2.

Since the flow guides 14 are installed without the possibility of movement, the design, if possible, can implement the drive of the sink compartment 2, which allows it to rotate along the axis and turn the dishes in the compartment 2 on different sides relative to the resulting chaotic splashes, that is, the guide 14 directing the flow of water 18 in the direction of the sink compartment 2, only part of the dishes in the compartment can be covered with splashes, only on one side, or part of the splashes can generally be blocked by the design of compartment 2. When the sink compartment 2 is rotated relative to the axis, both the dishes in the compartment and the displacement of the openings of the compartment move 2 with respect to the water flow from the guides 14, which makes it possible to ensure that all dishes in the sink compartment are washed in the same mode (with the same quality).

In this case, the rotation of the sink compartment 2 should be carried out with a lower number of revolutions than the rotation of the activator 5 to increase the safety of the dishes. Therefore, the rotation of the sink compartment 2 is carried out by a separate electric motor 11, mounted on the axis 10 of the sink compartment 2 or using a belt 12 (as shown in the images) which is installed on the axis 10 of the activator 5 and the axis 10 of the sink compartment 2, connecting the axes to each other and allowing to transmit rotation when the operation of the electric motor from the axis 10 of the activator 5 to the axis 10 of the sink compartment. Moreover, to ensure the difference in revolutions, the axis 10 of the activator 5 has a small diameter at the point of attachment of the belt 12, and the axis 10 of the shell compartment 2 at the point of attachment of the belt has a large diameter, providing the necessary gear ratio. For example, it is assumed that the activator can make at least 50 revolutions per minute and above, while the sink compartment will make no more than 10 revolutions per minute.

After washing the dishes, which is determined visually, by the operating time of the equipment, or by the timer, if one is built into the structure, it is necessary to open the lid 3 and use the ring 13 (pulling it up), which is connected to the valve with a chain or rope 15 7 open the valve 7, allowing the water to drain from the base 1 and, accordingly, from the sink compartment 2.

Next, the dishwashing process of the above scenario without the use of soap can be restarted to ensure that the dishes are rinsed.

Design features:

1. When washing dishes manually, the tap is disconnected from the hose 17, the cover 3 opens. Next, the dishes are washed manually in the classical way with a closed or open valve 7. In the semi-automatic method (the preferred method in the framework of the invention), washing of dishes is ensured by the operation of the structure (using the operation of the activator 5, the use of guides 14, etc.), while operating a sink with a built-in dishwasher, a person must place (pour) enough dishwashing detergent into the sink compartment 2 (pouring can be provided through hole 6, then when filling with water, water 18 will automatically mix with the detergent), must visually or over time track the filling of the sink compartment 2 water and turn on the electric motor 11. And then, after washing the dishes, turn off the electric motor 11 and drain the water from the base 1. With the automatic method, it is possible to complete the design with all the following items or by choice: a timer, an electric detergent dispenser, an automatic valve drive, a water level sensor and a supply valve water (by an automatic tap), but given that the addition of such devices to the structure will increase the cost and require additional space for placing devices, the automatic method is possible, but unlikely for mass use.

2. The tightness of the sink is ensured by the fact that the base 1 is made predominantly solid, seals 9 are additionally placed in the holes 8 intended for inserting the axes 10 of the activator 5 and the compartment of the sink 2, and the valve 7 is made using an elastic material (rubber, silicone).

3. In some cases, it is possible to operate a sink with a built-in dishwasher without a lid 3. Then water 18 from tap 4 is poured immediately into the sink compartment 2. But depending on the water level during washing, on the speed of the activator 5 or the location of the dishes in the sink compartment 2 water spray that will fly out of the sink.

4. At least one electric motor 11 is used in the design, which is installed on any of the axles 10, depending on such characteristics of the electric motor 11 as the number of revolutions per minute. Those. if the electric motor 11 can provide no more than 10 revolutions per minute, then it is installed on the axis 10 of the sink compartment 2, and the axis 10 of the activator 5 is connected through the belt 12. It is possible to use two or more (for example, if several activators 5 are provided) electric motors 11, for example one electric motor on the axis 10 of the activator 5, and the other on the axis 10 of the sink compartment 2.

5. The axles 10 can be connected to each other by means of a belt 12 or alternatively by a chain drive or by means of a gear connection.

6. The lid 3 is preferably made with outer and inner wall 16 providing an internal cavity for water to flow and enter through the holes in the lid 3. However, the lid can be made in any form, single-walled, flat, in the form of a hemisphere (as shown in the images), and etc.

7. The holes in the lid 3 are located at a distance from the center of the inner wall 16 to ensure better spreading of water 18 over the inner cavity of the lid 3.

8. The water level in the sink can be determined visually, by running the faucet 4, by a water level sensor, or alternatively by using a float, part of which will come out of the hole in the cover 3 to determine the level.

9. Since the activator 5 creates a rotating, chaotic flow of water inside the sink compartment 2, it is not recommended to wash light and too fragile dishes. For example, plastic forks and spoons can float to the surface of the water, making them less effective, and light glass goblets can be moved by the flow of water inside the sink compartment 2.

10. The electric motor 11 has a place for connecting the power supply, so that it can be connected to the electrical network through a socket or a separate switch.

Usage example:

A person puts the dishes in the sink compartment 2 and closes the lid 3. Then he pours the necessary amount of detergent into the hole 6 on the lid 3 and, by connecting the hose 17 to the lid 3 and the faucet 4, opens the faucet 4, the water from which flows through the hose 17 into the lid 3 through the hole 6 and through the holes it merges into the compartment of the sink 2. A person measures the time during which the compartment of the sink 2 is filled with water and closes the tap 4. Then he turns on the power supply to the electric motor 11. A rotating flow of water is created inside the base 1, randomly changing direction on the guides 14 , the sink compartment 2 slowly turns on the axis 10. Then, having measured the required time, the person turns off the power supply to the electric motor 11, stopping the operation of the dishwasher structure, opens the lid 3 and visually assesses the condition of the dishes. If the washing is done poorly, then the lid 3 closes and the person turns on the electric motor 11 again for a certain time. If the washing is completed, then the person, using the ring 13 connected by a rope or chain 15 to the valve 7, drains the water from the base 1 and removes the dishes from the sink compartment 2 or manually rinses the dishes and removes them or, after draining the soapy water, repeats the dishwashing process already without detergent for rinsing and only then, having previously raised the lid 3, removes the dishes from the sink compartment 2.
