Example 1

Referring to fig. 1 to 3, the present embodiment provides a high water level protection device that can be applied to a dishwasher.

Specifically, referring to fig. 2 and 3, in the present embodiment, the high water level protection device includes a housing 1 and a partition plate 2. A hollow cavity is provided in the housing 1, and a partition plate 2 is provided in the hollow cavity to divide the hollow cavity into an overflow input cavity 11 and an overflow output cavity 12. The top of overflow input chamber 11 and overflow output chamber 12 can communicate, and the bottom of overflow input chamber 11 is provided with overflow input interface 112, and the bottom of overflow output chamber 12 is provided with overflow output interface 121, and the surface of baffle 2 that is located overflow input chamber 11 is protruding to be equipped with first buffer rib 21.

It can be understood that the cavity is divided into the overflow input cavity 11 and the overflow output cavity 12 by the partition plate 2, and the overflow input cavity 11 and the overflow output cavity 12 form a hanging structure, so that the occupied space of the hanging structure can be reduced, and the miniaturized design of the high water level protection device is facilitated. The overflow input port 112 is disposed at the bottom of the overflow input chamber 11, so that the water level in the overflow input chamber 11 is raised from bottom to top.

When the high water level protection device is applied to a dish washer, the water level at the communication part of the overflow input cavity 11 and the overflow output cavity 12 is a preset water level. When the water level of the liner 10 is higher than the preset water level, water enters the overflow output cavity 12 through the overflow input cavity 11 and is guided to the overflow detection device 40, and overflow alarm is carried out by the overflow detection device 40. If the water in the liner 10 fluctuates due to disturbance, the first buffer rib 21 plays a role of blocking, so that the fluctuation of the water flow can be restrained, the condition that the water disturbance easily exceeds the preset water level is reduced, and the overflow false alarm condition caused by the water disturbance is further improved.

Optionally, in the overflow input chamber 11, the blocking range of the first buffer rib 21 is less than half the width of the overflow input chamber 11. As shown in fig. 2, D in fig. 2 represents the size of the unblocked area of the first buffer rib 21, D represents the width of the overflow input chamber 11, and D > 0.5D.

Optionally, the first buffer rib 21 on the partition board 2 is arranged at an included angle with the partition board 2.

Optionally, referring to fig. 1, the housing 1 is provided with a first connecting portion 14 and a second connecting portion 15, the overflow input interface 112 is disposed on the first connecting portion 14, and the overflow output interface 121 is disposed on the second connecting portion 15. The design is convenient for being installed and connected with the overflow input pipe 20 and the overflow output pipe 30 of the dish washer.

Optionally, in order to prevent mosquitoes from climbing into the liner 10 from the high water level protection device, in this embodiment, the high water level protection device further includes a sealing baffle 3, and the sealing baffle 3 is disposed in the hollow cavity, and can selectively open or close the top overflow opening 111 of the overflow input cavity 11, so that the upper ends of the overflow input cavity 11 and the overflow output cavity 12 are switched between the communicating state and the non-communicating state.

It can be understood that when the water level of the dishwasher is lower than the preset water level, no water overflows into the overflow output cavity 12, at this time, the sealing baffle 3 closes the top overflow opening 111 of the overflow input cavity 11, and the upper ends of the overflow input cavity 11 and the overflow output cavity 12 are in a non-communication state, so that the influence of the user experience caused by the external mosquitoes entering the inner container 10 after entering the overflow input cavity 11 through the top overflow opening 111 is avoided.

When the water level of the dishwasher is higher than a preset water level, the water pushes the sealing stopper 3 under the buoyancy of the water, and the sealing stopper 3 opens the top overflow opening 111, so that the upper ends of the overflow input chamber 11 and the overflow output chamber 12 are in a communicating state.

Optionally, in this embodiment, the upper end of the sealing stopper 3 is hinged to the inner wall of the housing 1, and the other end abuts against the top end of the partition 2 in a free state to close the top overflow opening 111 of the overflow input chamber 11; the sealing stopper 3 can be rotated by buoyancy of the liquid in the overflow input chamber 11 to open the top overflow opening 111 of the overflow input chamber 11.

Optionally, the sealing baffle 3 is made of rubber material, so that the sealing baffle 3 is convenient to be pushed by water and has light weight.

Optionally, in order to ensure that the top overflow opening 111 faces the sealing baffle 3, and further ensure that the buoyancy of the water overflowing from the overflow input cavity 11 acts on the sealing baffle 3, in this embodiment, a baffle 22 is disposed on the inner side wall of the overflow input cavity 11, and a top overflow opening 111 is formed between the baffle 22 and the partition 2, and when the sealing baffle 3 contacts with both the partition 2 and the baffle 22, the sealing baffle 3 closes the top overflow opening 111.

Referring to fig. 2, the hinge point of the sealing stopper 3 is located above the baffle 22, and the free end of the sealing stopper 3 can abut against the baffle 22 and the partition 2 under the action of its own gravity, thereby blocking the top overflow opening 111. When the water level of the dishwasher is higher than the preset water level, the water pushes the free end of the sealing stopper 3 away from the baffle 22 and the partition plate 2 under the buoyancy force to open the top overflow opening 111.

Wherein the arrows in fig. 3 indicate the water flow direction. By adopting the sealing baffle 3 in the embodiment, a driving piece aiming at the sealing baffle 3 does not need to be specially arranged, and the buoyancy of liquid is utilized to control the opening and closing of the top overflow opening 111, so that the structure can be simplified, and the product cost can be reduced.

Optionally, a second buffer rib 23 is convexly arranged on the inner wall of the shell 1, which is positioned in the overflow input cavity 11, and the second buffer rib 23 and the first buffer rib 21 are arranged in a staggered manner. The second buffer rib 23 is provided to further buffer the liquid entering the overflow input chamber 11, so that the liquid level in the overflow input chamber 11 is as stable as possible. Taking the orientation shown in fig. 2 as an example, the second buffer rib 23 and the first buffer rib 21 are arranged in a staggered manner along the height direction of the high water level protection device. The two are arranged in a staggered way, so that the buffer effect is enhanced.

Optionally, in order to implement the installation of the high water level protection device on the liner 10, in this embodiment, the housing 1 is provided with an installation hole 13.

Preferably, the mounting hole 13 is a threaded blind hole, and the blind end of the mounting hole 13 is positioned in the hollow cavity. When the housing 1 is mounted to the inner container 10, the screw 132 passes through the side wall of the inner container 10 from the inside of the inner container 10 and then enters the mounting hole 13 to fix the housing 1 to the outer side wall of the inner container 10. Further, the housing 1 is integrally formed with a mounting post 131, the mounting post 131 is located in the overflow output cavity 12, the mounting post 131 is provided with a mounting hole 13, and the mounting hole 13 penetrates through a side wall of the housing 1
