AI Technical Summary

Technical Problem

The floating ball foam in the existing dishwasher protective plate is flat. When water accumulates due to the surface tension of the water, it takes more than 400m of water to trigger the overflow alarm. The alarm time is longer and the risk is greater.

Method used

A dishwasher protective plate structure is designed, including the board body, installation groove, sink connection, sink drain and float foam. The bottom wall of the installation groove is recessed to form a water guide groove. The water guide groove extends to the connection between the side wall of the installation groove and the water connection groove. The float foam is placed in the position of the installation groove. The water flow first gathers in the installation groove. When the water volume reaches about 100ml, the floating foam can float, and then triggers the overflow alarm when about 250ml.

Benefits of technology

When a dishwasher leaks, less water flow can trigger the overflow alarm, reducing the overflow alarm time and reducing the risk.

Abstract

The utility model discloses a dish-washing machine protection plate structure which comprises a plate body part, an installation groove and a water receiving groove communicated with the installation groove are formed in the plate body part, a water guiding groove is formed in the bottom wall of the installation groove in a sunken mode, and the water guiding groove extends to the side wall of the installation groove and the connecting position of the installation groove and the water receiving groove. According to the dish-washing machine protection plate structure, when the dish-washing machine leaks water, water flow is gathered at the position of the floating ball foam of the protection plate, due to the fact that the installation groove is formed below the floating ball foam, the water flow is firstly gathered in the installation groove, when the water amount reaches about 100 ml, the floating ball foam can float, and then when the water amount reaches about 250 ml, the microswitch located above the floating ball foam is triggered to give an overflow alarm; the water flow is less, and the risk is lower.

Description

Technical field:

[0001] The utility model relates to a dishwasher protection plate structure, which belongs to the technical field of dishwashers. Background technology:

[0002] The float bubble in the existing dishwasher protection plate is flat. Due to the surface tension of water, when water gathers at the float bubble, more than 400m3 of water is required to trigger the overflow alarm. The alarm time is long and the risk is relatively high.

[0003] Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Utility model content:

[0004] The utility model provides a dishwasher protection plate structure in order to solve the problems existing in the above-mentioned prior art, which can solve the problems that the float foam on the existing protection plate floats up late, a large amount of water is required, the overflow alarm time is long, and the risk is relatively large.

[0005] The technical solutions adopted by the utility model include: a dishwasher protective plate structure, including a plate body, a mounting groove and a water receiving groove connected to the mounting groove are formed on the plate body, the bottom wall of the mounting groove is recessed to form a water diversion groove, and the water diversion groove extends to the side wall of the mounting groove and the connection between the mounting groove and the water receiving groove.

[0006] Furthermore, the water diversion groove includes a first water diversion groove and a second water diversion groove, the first water diversion groove extends to the side wall of the installation groove, and the second water diversion groove extends to the connection between the installation groove and the water receiving groove.

[0007] Furthermore, the depth of the first water diversion groove is 0.5 mm.

[0008] Furthermore, the depth of the second water diversion groove is 0.5 mm.

[0009] Furthermore, a float foam is installed on the plate body at the position of the installation groove, a positioning column is protruded on the bottom wall of the installation groove, and a positioning hole is formed on the float foam at a position opposite to the positioning column.

[0010] Furthermore, a difference of 2-3 mm is set between the lowest end of the mounting groove and the highest end of the plate body.

[0011] The utility model has the following beneficial effects: with the dishwasher protective plate structure of the utility model, when the dishwasher leaks, the water flow gathers at the float foam of the protective plate. Since the installation groove is placed under the float foam, the water flow first gathers in the installation groove. When the water volume reaches about 100ml, the float foam can float up, and then when it is about 250ml, the micro switch located above the float foam is triggered to thereby trigger an overflow alarm, with less water flow and less risk. Description of the drawings:

[0012] Figure 1 This is a schematic diagram of the structure of the protective plate of the dishwasher of the present utility model.

[0013] Figure 2 This is a schematic diagram of the protective plate structure and the floating ball foam installation of the dishwasher of the utility model. Specific implementation method:

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] The utility model dishwasher protection plate structure comprises a plate body 1, on which a mounting groove 10 and a water receiving groove 11 connected to the mounting groove 10 are formed. The bottom wall of the mounting groove 10 is recessed to form a water diversion groove 100, which comprises a first water diversion groove 101 and a second water diversion groove 102. The first water diversion groove 101 extends to the side wall of the mounting groove 10, and the second water diversion groove 102 extends to the connection between the mounting groove 10 and the water receiving groove 11. The depths of the first water diversion groove 101 and the second water diversion groove 102 are both 0.5 mm.

[0016] A float foam 2 is installed on the plate body 1 at the position of the mounting groove 10, a positioning column 103 is protruded on the bottom wall of the mounting groove 10, and a positioning hole 20 is formed on the float foam 2 at a position opposite to the positioning column 103. The float foam 2 is positioned on the mounting groove 10 by installing the positioning column 103 in the positioning hole 20.

[0017] In the utility model dishwasher protection plate structure, when water flows into the plate body 1 or the water receiving groove 11, it is introduced to the position of the installation groove 10 through the first water guide groove 101 or the second water guide groove 102, so that the water flow is gathered to the position of the installation groove 10. Since the installation groove 10 is arranged directly below the float foam 2, the float foam is lifted up after the water flow is gathered. In order to more conveniently introduce water in the plate body or the water receiving groove into the installation groove, the lowest end of the installation groove and the highest end of the plate body are set to have a difference of 2-3mm.

[0018] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
