Description

Technical Field

[0001] The utility model relates to the field of dishwashers, in particular to a double-channel table dishwasher. Background Art

[0002] A tabletop dishwasher is a dishwasher that can be placed on a tabletop for use and is easy to move. Its consumer group is generally families who did not consider installing a dishwasher during renovation. Since there is no cabinet reserved for the dishwasher during home renovation, the dishwasher cannot be embedded in the cabinet, so the only choice is to place a tabletop dishwasher on the tabletop for use. There are two types of tabletop dishwashers. One is a reserved water tank dishwasher, which is characterized by a water tank pre-set on the dishwasher and water supply through the water tank, but the disadvantage is that the addition of a water tank results in a larger volume and occupies more space. The other is a faucet-connected dishwasher, which is directly connected to the faucet through a pipe and directly supplies water through the faucet, but the disadvantage is that this method limits the location of the dishwasher and cannot be too far from the faucet. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide a dual-channel table dishwasher.

[0004] The technical solution adopted by the utility model to solve the problem is: a dual-channel table-top dishwasher, including a dishwasher main unit, wherein the dishwasher main unit is provided with a washing inner tank, a door body, a spray arm, an electric heating element, an inner water channel assembly, a drain pipe and a drain valve;

[0005] The surface of the dishwasher main unit is provided with a faucet water inlet and a water pipe water inlet, the dishwasher main unit is provided with a faucet solenoid valve connected to the faucet water inlet, the dishwasher main unit is provided with a water supply pump connected to the water pipe water inlet, the faucet solenoid valve is connected to the water circuit in the box through a first pipeline, and the water supply pump is connected to the water circuit in the box through a second pipeline;

[0006] A first check valve is arranged between the water inlet of the water pipe and the water channel in the box.

[0007] As a further improvement of the above technical solution, a second check valve is provided between the faucet solenoid valve and the water channel in the box.

[0008] As a further improvement of the above technical solution, a three-way valve is arranged in the dishwasher main unit, and the three-way valve includes an outlet connected to the water circuit in the box and two inlets respectively connected to the first pipeline and the second pipeline, the first check valve is arranged between the water supply pump and the three-way valve, and the second check valve is arranged between the faucet solenoid valve and the three-way valve.

[0009] As a further improvement of the above technical solution, the first check valve and the second check valve are respectively arranged in the two inlets of the three-way connection.

[0010] As a further improvement of the above technical solution, flow sensors are provided on both the first pipeline and the second pipeline.

[0011] The beneficial effect of the utility model is as follows: since a tap water inlet and a water pipe water inlet are provided on the surface of the dishwasher main unit, the tap water inlet can be directly connected to the faucet through a water supply pipe, and then the faucet is in an open state for a long time, and the faucet solenoid valve controls its on and off to supply or stop water. The water pipe water inlet can be connected to a water pipe outside the dishwasher, and then water is filled through a bucket. When it is needed, the water pipe is placed in the bucket and water is sucked through a water supply pump to supply water to the water channel in the box. During use, since the water supply pump does not have the function of limiting the diversion of water flow, if only the tap is used for water supply, the water in the water channel in the box may flow back to the outside of the dishwasher along the water pipe water inlet. For this reason, it is preferred to set a first check valve between the water pipe water inlet and the water channel in the box to prevent water backflow. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0019] Reference Figure 1 to Figure 2 A dual-channel table-top dishwasher includes a dishwasher main unit 10, wherein the dishwasher main unit 10 is provided with a washing liner, a door body, a spray arm, an electric heating element, an in-box water channel assembly, a drain pipe and a drain valve;

[0020] The surface of the dishwasher main unit 10 is provided with a faucet water inlet 20 and a water pipe water inlet 30, the dishwasher main unit 10 is provided with a faucet solenoid valve 21 connected to the faucet water inlet 20, the dishwasher main unit 10 is provided with a water supply pump 31 connected to the water pipe water inlet 30, the faucet solenoid valve 21 is connected to the water path in the box through a first pipeline 22, and the water supply pump 31 is connected to the water path in the box through a second pipeline 32;

[0021] A first check valve is provided between the water pipe water inlet 30 and the water channel in the box.

[0022] Since the faucet water inlet 20 and the water pipe water inlet 30 are provided on the surface of the dishwasher main unit 10, the faucet water inlet 20 can be directly connected to the faucet through a water supply pipe, and then the faucet is in an open state for a long time, and the faucet solenoid valve 21 controls its on and off to supply or stop water supply. The water pipe water inlet 30 can be connected to a water pipe outside the dishwasher, and then fill water through a bucket. When it is needed, the water pipe is placed in the bucket and water is sucked through the water supply pump 31 to supply water to the water channel in the box. During use, since the water supply pump 31 does not have the function of limiting the diversion of water flow, if only the faucet is used for water supply, the water in the water channel in the box may flow back to the outside of the dishwasher along the water pipe water inlet 30. For this reason, it is preferred to set a first check valve between the water pipe water inlet 30 and the water channel in the box to prevent water from flowing back, and in the first pipeline 22, the faucet solenoid valve 21 itself has a cut-off function.

[0023] In the above scheme, the user still needs to choose to set the water source. In order to simplify the user's operation, it is preferred that a second check valve is provided between the faucet solenoid valve 21 and the water path in the box. In this way, the user only needs to choose to turn on the dishwashing function when using it. After turning on the dishwashing function, the water supply pump 31 and the faucet solenoid valve 21 are turned on at the same time. Only one of the first pipeline 22 and the second pipeline 32 needs to have water to work. If only the faucet supplies water, due to the setting of the first check valve, water will not flow out to the outside of the dishwasher host 10 along the water path of the water supply pump 31. If only a bucket is used to supply water, although the faucet solenoid valve 21 is opened, due to the effect of the second check valve, water will not flow back along the water path of the faucet solenoid valve 21. The user operation is more fool-proof.

[0024] For further optimization, it is preferred that a tee 40 is provided in the dishwasher host 10, and the tee 40 includes an outlet connected to the water path in the box and two inlets respectively connected to the first pipeline 22 and the second pipeline 32, the first check valve is arranged between the water supply pump 31 and the tee 40, and the second check valve is arranged between the faucet solenoid valve 21 and the tee 40.

[0025] Considering that if the first check valve and the second check valve are arranged too close to the water supply pump 31 and the faucet solenoid valve 21, water will accumulate in the first pipeline 22 or the second pipeline 32, it is preferred that the first check valve and the second check valve are respectively arranged at the two inlets of the tee 40. Therefore, when only one of the first pipeline 22 and the second pipeline 32 is supplied with water, no water will accumulate in the other pipeline.

[0026] For further optimization, it is preferred that flow sensors are provided on both the first pipeline 22 and the second pipeline 32, so that after the user turns on the dishwashing function, the water supply pump 31 and the faucet solenoid valve 21 will be turned on at the same time, and then the flow sensor will automatically determine which water channel is used for water supply according to the flow data in the first pipeline 22 and the second pipeline 32. If the first pipeline 22 supplies water, the water supply pump 31 will be turned off; if the second pipeline 32 supplies water, the faucet solenoid valve 21 will be turned off, which is more intelligent and saves energy.

[0027] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
