Description

Technical field

[0001] The utility model relates to a novel flow meter structure and a dishwasher. [Background Technology]

[0002] Existing dishwashers often use an integrated approach to combine multiple functions such as flow meters, breathers, and drainage systems. In large dishwashers, this functional module is often assembled separately. The flow meter part has the highest failure rate. Failure rates such as inaccurate metering accuracy and continuous water inflow remain high under complex transportation conditions. Repairing the flow meter module requires replacing other parts, resulting in cost waste. This problem is even more serious in desktop dishwashers because desktop dishwashers often use oversized water tanks, and the water tanks are even directly installed on the dishwasher's inner tank. Once the flow meter part fails, the entire machine may be scrapped, and the repair cost is too high.

[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]

[0015] Figure 2 2 is a cross-sectional view of the flow meter of this embodiment. [Specific implementation method]

[0016] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0017] See attached Figure 1-2 The present application provides a novel flow meter structure, which includes a housing 1 having an internal water inlet chamber, an impeller chamber, and a water outlet chamber. The water inlet chamber, the impeller chamber, and the water outlet chamber are sequentially connected. The water inlet chamber is connected to a first water inlet pipe 2 and a second water inlet pipe 3. The first water inlet pipe and the second water inlet pipe can be connected to a water tank and municipal water, respectively, to achieve a dual-mode water inlet function. The water outlet chamber is connected to a water outlet pipe 4, which is used to connect to the breather on the dishwasher. An impeller 5 is provided in the impeller chamber. A sensor 6 for sensing the rotation of the impeller is provided on the housing 1. The water flow is sensed by the rotation of the impeller. Specifically, the sensor is a reed switch, and the impeller is provided with a magnet. The water inlet chamber is provided with a check structure at the first water inlet pipe and the second water inlet pipe. The check structure can close the water path when one water inlet pipe is opened to inlet water, while the other water inlet pipe is closed.

[0018] The water inlet cavity is provided with a first water inlet area 7 and a second water inlet area 8. The first water inlet pipe 2 is connected to the bottom of the first water inlet area, and the second water inlet pipe 3 is connected to the bottom of the second water inlet area. The output end of the first water inlet pipe and the output end of the second water inlet pipe are provided with the non-return structure. The first water inlet area and the second water inlet area are provided. When water flows into one of the water inlet pipes, the other water inlet area can be quickly filled. Moreover, the water pressure acts on the non-return structure to achieve a better non-return effect.

[0019] Preferably, the non-return structure is a non-return plate, which includes a sealing portion 9 and a connecting portion 10. The sealing portion and the connecting portion are connected by a flexible portion 11. The connecting portion is fixed on the outer shell 1. Specifically, the outer shell is provided with an installation position for the connecting portion to be clamped. When both water inlet pipes are in a state where no water is flowing, the non-return plate is in a blocking state. When water is flowing in, the water flow will flush the water stop plate and let in water.

[0020] The sealing portion 9 is provided with a concave recessed portion 91 on the side facing the water inlet cavity. When water enters one of the water inlet pipes, the water will enter the water inlet area connected to the other water inlet pipe and fill it. Then, the water pressure presses the recessed portion to close the water inlet pipe, thereby achieving the purpose of non-return.

[0021] The impeller chamber includes an impeller mounting area 12 and a water inlet channel 13. The water inlet channel is used to connect the water inlet chamber and the water outlet chamber. The impeller 5 is arranged in the impeller mounting area 12, and at least part of the impeller blades extend into the water inlet channel to ensure that the water flow directly drives the impeller to rotate when passing through the water inlet channel.

[0022] This embodiment further provides a dishwasher, which is equipped with the above-mentioned flow meter structure, and the water outlet pipe 4 of the flow meter structure is connected to the breather on the dishwasher.

[0023] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the content disclosed in the present invention should be included in the protection scope recorded in the claims.
