Description

Technical Field

[0001] This utility model relates to the technical field of drainage equipment, and more specifically, to a drainage floor drain. Background Technology

[0002] Floor drains are an indispensable part of home renovation. They are mainly installed in areas requiring drainage, such as bathrooms, kitchens, and balconies, to collect and discharge sewage. In addition to fulfilling basic drainage functions, floor drains also need to consider factors such as odor prevention. Existing methods for preventing odors include water seals, which isolate sewer odors by using water to prevent their spread.

[0003] In actual use, the water seal height decreases over time, leading to a loss of odor prevention. To prevent the water seal from drying out, existing technologies employ a water replenishment device to maintain it at the required height. However, while the water seal can be replenished via this device, it may freeze in cold weather, causing drainage blockages or even serious clogging. Utility Model Content

[0031] The water replenishment mechanism 300 replenishes the water seal within the drain body 100, preventing the water seal from drying out and causing odors to escape from the sewer. The anti-freeze mechanism prevents the water seal within the drain body 100 from freezing in cold weather, thus preventing drainage blockages and improving the hygiene and comfort of the living environment. The cover plate 200 prevents accidental stepping or falling objects. Preferably, the control box 600 includes a box body and a PLC controller housed within the box body. The control box 600 can be connected to the outer wall of the drain body 100, such as... Figure 1 As shown.

[0032] like Figure 1 and Figure 2 As shown, the anti-freeze mechanism includes a heating mechanism 400 that is communicatively connected to the control box 600. The heating mechanism 400 is connected to the outer wall of the drain body 100. The heating mechanism 400 is designed to heat the water seal in cold weather, preventing the water seal from freezing and causing drainage blockage. The heating mechanism 400 includes a first housing 410 and a plurality of heating wires 420 arranged within the first housing 410. The heating wires 420 are communicatively connected to the control box 600. The first housing 410 is an arc-shaped housing that is adapted to and connected to the outer wall of the drain body 100.

[0033] In this embodiment, the heating wire 420 is electrically connected to the PLC controller. The heating wire 420 is arranged along the extension direction of the arc-shaped housing, and multiple heating wires 420 can be arranged at equal or unequal intervals. The arc-shaped housing is fixedly connected to or detachably connected to the outer wall of the drain body 100. The arc-shaped housing can be configured as a fully enclosed structure, or it can be configured as a structure with an opening and a sealing cover at the opening.

[0034] like Figure 2 and Figure 3 As shown, the antifreeze mechanism includes a stirring mechanism 500 connected to the bottom of the drain body 100, with the stirring end of the stirring mechanism 500 extending into the drain body 100. The stirring mechanism 500 is designed to stir the water seal in cold weather, preventing the water seal from freezing and causing drainage blockage. The stirring end of the stirring mechanism 500 includes a rotating disk 510 and several protrusions 520 connected to the rotating disk 510. The stirring mechanism 500 includes a driving member that is drivenly connected to the rotating disk 510, with the fixed end of the driving member connected to the outside of the drain body 100.

[0035] In this embodiment, the upper surface of the rotating disk is connected to multiple protrusions 520, which are arranged in a spoke-like pattern. Specifically, the protrusions 520 can be configured as raised strips or blocks, or as spiral structures, depending on the actual application scenario. In this embodiment, the driving component includes a second housing 530 and a motor 540 housed within the second housing 530. The output end of the motor 540 extends into the drain body 100 and connects to the rotating disk 510. The second housing 530 is fixedly connected to the bottom of the drain body 100. Specifically, the motor 540 can be electrically connected to a PLC controller via a motor controller, or the motor controller can be connected and controlled via WIFI. Preferably, the motor 540 is a micro motor.

[0036] like Figure 3 and Figure 4As shown, the drain body 100 includes a connecting pipe 110 and a drain cup 120 detachably connected to the connecting pipe 110. A gap exists between the connecting pipe 110 and the drain cup 120. The side wall of the connecting pipe 110 has a first notch structure 111, and the side wall of the drain cup 120 has a second notch structure 121 corresponding to the first notch structure 111. A cover plate 200 is detachably connected to the connecting pipe 110. A water replenishment mechanism 300 is connected to the drain cup 120, and an antifreeze mechanism is connected to the drain cup 120. The connecting pipe 110 is used to guide water into the drain cup 120, and the drain cup 120 is used to store water and form a water seal. The first notch structure 111 and the second notch structure 121 are used for drainage. In this embodiment, the connecting pipe 110 is vertically arranged, and the first notch structure 111 is located near the upper end of the connecting pipe 110. Preferably, the drain cup 120 is a cylindrical structure with a closed bottom, and the outline of the arc-shaped shell of the first shell 410 can be set as a semi-ring structure that matches the side wall of the cylindrical structure.

[0037] like Figure 3 and Figure 4 As shown, the upper end of the connecting pipe 110 is connected to a receiving seat 112. The receiving seat 112 has a connecting hole communicating with the connecting pipe 110, and the upper end of the receiving seat 112 is an open structure. The lower surface of the cover plate 200 is connected to a snap-fit ​​plate 220 adapted to the open structure of the receiving seat 112. The snap-fit ​​between the cover plate 200 and the drain body 100 is achieved by the snap-fit ​​plate 220 snapping into the receiving seat 112. When the connecting pipe 110 is sleeved with the drain cup 120, the receiving seat 112 abuts against the top of the drain cup 120. In this embodiment, the outer contour of the receiving seat 112 can be set as rectangular, circular, or elliptical, and the snap-fit ​​plate 220 is a structure adapted to the contour of the receiving seat 112. The cover plate 200 is provided with several through holes 210, which can be used for drainage. The receiving seat 112 and the snap-fit ​​plate 220 are designed to ensure a tight seal between the cover plate 200 and the drain body 100. In this embodiment, the through hole 210 is a long, narrow hole, which can be used to isolate large amounts of dirt or debris, preventing the drain from becoming clogged.

[0038] like Figures 3 to 5 As shown, the water replenishment mechanism 300 includes a sensor 310 and a delivery pipe 320. The sensor 310 is connected to the inner wall of the drain body 100 and is communicatively connected to the control box 600. One end of the delivery pipe 320 is connected to the inside of the drain body 100, and the other end is used to connect to the water source. A valve 330 that is communicatively connected to the control box 600 is connected to the delivery pipe 320.

[0039] In this embodiment, the sensor 310 is connected to the inner wall of the drain cup 120. The sensor 310 is electrically connected to the PLC controller and is located near the bottom of the drain cup 120. Specifically, when the height of the drain cup 120 is h, the sensor 310 is located at 1 / 4h to 1 / 3h. Preferably, the sensor 310 is a liquid level sensor. In this embodiment, one end of the delivery pipe 320 is connected to the inside of the drain cup 120, and a filter screen is provided at this end. It should be noted that the delivery pipe 320 can be composed of multiple bent pipe sections and straight pipe sections connected together. The number of bent pipe sections and the splicing order can be selected according to the actual use scenario. Preferably, the valve 330 can be a solenoid valve electrically connected to the PLC controller.

[0040] like Figure 4 As shown, in this embodiment, the lower end of the connecting pipe 110 is provided with a clearance position 113 for the clearance sensing element 310, which can prevent the connecting pipe 110 from interfering with the sensing element 310.

[0041] The working principle of a drainage floor drain in this embodiment is as follows:

[0042] Water passes through the through hole 210 and then sequentially through the receiving seat 112 and connecting pipe 110 into the drain cup 120, where it accumulates to form a water seal. The water in the drain cup 120 can drain through the first notch structure 111 and the second notch structure 121. When the sensor 310 detects that the water seal is below a preset height threshold, the control box 600 controls the valve 330 to open and replenish water. In cold weather, the control box 600 can also control the heating wire 420 to start heating, or control the motor 540 to start the rotating disk 510 to rotate. The protrusion 520 can pump the water seal to prevent it from freezing. It should be noted that the heating mechanism 400 and the stirring mechanism 500 can operate simultaneously or independently.

[0043] Example 2

[0044] This embodiment is the second embodiment of a drainage floor drain according to the present invention. This embodiment is similar to the first embodiment, except that, as follows: Figure 4 As shown, the control box 600 can also be mounted on the delivery pipe 320. In this embodiment, a temperature sensor 430, which is communicatively connected to the control box 600, is provided inside the drain body 100. The temperature sensor 430 is used to sense the temperature of the water seal, allowing the control box 600 to control the start and stop of the heating mechanism 400 based on the temperature of the water seal. In this embodiment, the temperature sensor 430 is connected to the inner wall of the drain cup 120 and is located near the bottom of the drain cup 120.

[0045] The working principle of a drainage floor drain in this embodiment is as follows:

[0046] When the temperature sensor 430 detects that the temperature of the water seal is lower than the preset first temperature threshold, the control box 600 controls the heating mechanism 400 to heat the water seal; during the heating process, when the temperature sensor 430 detects that the temperature of the water seal is higher than the preset second temperature threshold, the heating mechanism 400 is controlled to stop heating.

[0047] Example 3

[0048] This embodiment is the third embodiment of the drainage floor drain of this utility model. This embodiment is similar to the first embodiment, except that, as Figure 5 As shown, a handle 230 is connected to the upper surface of the cover plate 200. The handle 230 facilitates gripping the cover plate 200 and makes it easy to open and close the cover plate 200. In this embodiment, the handle 230 can be a detachable handle or a fixed handle.
