Description

Technical Field

[0001] This utility model belongs to the technical field of water purification equipment, and specifically relates to an anti-flow drain pipe type water collection box and a water dispenser having the same. Background Technology

[0002] In existing water dispenser designs, the water collection box is typically connected to the drain pipe via a bottom drain outlet to collect overflowing water. Some high-end models also include a heating element drain pipe to discharge residual wastewater from the heating element. However, in traditional designs, the heating element drain pipe and the water collection box drain pipe are often directly connected, leading to cross-contamination at the point where the two water streams meet. Specifically, drainage from the water collection box may flow backward into the heating element drain pipe, or wastewater from the heating element may backflow into the water collection box. This cross-contamination not only causes cross-contamination of water quality, affecting drinking water hygiene, but may also lead to abnormal heating element drainage function and even equipment malfunction.

[0003] In existing technologies, some solutions attempt to alleviate crossflow problems by optimizing pipeline layout or adding check valves, but such designs are often complex and costly, and check valves are prone to clogging due to scale or impurities. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides an anti-flow drain pipe type water collection box and a water dispenser with the same.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a drain pipe-type water collection box with anti-flow-through. The bottom of the water collection box is connected to a drain pipe, and a hot water tank drain pipe is connected to the side wall of the drain pipe. A baffle plate is installed in the drain pipe at the junction of the hot water tank drain pipe and the drain pipe. The baffle plate divides the drain pipe at the junction of the two pipes into two mutually isolated sub-channels. One sub-channel is connected to the hot water tank drain pipe, and the other sub-channel is connected to the water collection box.

[0007] Furthermore, the upper end of the baffle plate is fixed to the inner wall of the drain pipe on the upper side of the hot water tank drain pipe, and transitions to the direction facing the hot water tank drain pipe through a bending structure.

[0008] Furthermore, the baffle plate includes an inclined plate and a vertical plate, with the upper end of the inclined plate fixed to the inner wall of the drain pipe and the lower end integrally formed to transition to the vertical plate.

[0009] Furthermore, the side of the baffle plate is fixed to the inner wall of the drain pipe, and the lower end of the baffle plate extends along the axial direction of the drain pipe.

[0010] Furthermore, the front end of the hot water tank drain pipe is equipped with an odor-proof bend.

[0011] Furthermore, the bottom of the water collection box is provided with a drain outlet, and the water collection box is connected to the drain pipe through the drain outlet. The hot water tank drain pipe is located at the drain pipe near the drain outlet.

[0012] Furthermore, the inner diameter of the drain outlet is larger than the inner diameter of the drain pipe.

[0013] Furthermore, the bottom of the water collection box and the front end of the drain outlet are provided with a storage opening with an inner diameter larger than that of the drain outlet, and a filter screen is placed in the storage opening.

[0014] This utility model also provides a water dispenser, which includes the above-mentioned anti-flow type drain pipe water collection box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model's anti-flow-through type drain pipe water collection box, through optimized structural design, can prevent the drainage from the water collection box from flowing into the drain pipe of the heating element, and at the same time prevent the drainage from the heating element from flowing back into the water collection box, so that the drainage of the two does not interfere with each other, effectively solving the problem of crossflow at the drain outlet of the water collection box.

[0022] The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings. Contents not explicitly described in the embodiments of this utility model are all prior art, and those skilled in the art can refer to existing conventional technical solutions for implementation.

[0023] This embodiment uses Figure 1-2The structure of the drain pipe type water collection box is explained in detail using the water dispenser shown as an example. This water dispenser is a vertical water dispenser, mainly including a display panel 1, a water outlet 2, a water collection box 3, and a bottom door 4. The water dispenser is equipped with a heating element for heating purified water.

[0024] In this embodiment, the structure of the water pipe type water collection box is as follows: Figure 3 As shown. The water collection box 3 consists of a front baffle 3-1, side baffles, a rear baffle, and a bottom plate 3-2. The drain pipe 5 is connected to the bottom of the water collection box 3, forming the main drainage channel for draining the water accumulated in the water collection box to the outside. The drain pipe 5 is connected to the side wall of the drain pipe 5 by the heat tank drain pipe 6, and the drainage from the heat tank is collected through the heat tank drain pipe 6 and discharged through the drain pipe 5.

[0025] In this embodiment, a drain outlet 3-3 with a diameter larger than that of the drain pipe 5 is preferably provided at the bottom of the water collection box 3. The water collection box 3 is connected to the drain pipe 5 through this drain outlet 3-3. For example, designing the diameter of the drain outlet 3-3 to be 20% larger than that of the drain pipe 5 can effectively reduce drainage resistance and the risk of blockage, ensuring smooth drainage. In this embodiment, a storage opening 3-4 is also provided at the bottom of the water collection box 3 and at the front end of the drain outlet 3-3. The inner diameter of the storage opening 3-4 is larger than that of the drain outlet, and a filter screen is placed in the storage opening 3-4.

[0026] The connection between the heating element drain pipe 6 and the drain pipe 5 is located in the drain pipe section near the drain outlet 3-3 of the water collection box 3. This structural design can further reduce water flow resistance and simplify the pipe layout. In this embodiment, an odor-proof bend is preferably provided at the front end of the heating element drain pipe 6. When there is no water flow, the odor-proof bend isolates the air flow in the pipe through the water accumulated in the bend, thereby playing a role in preventing odors. Specifically, for example, the heating element drain pipe 6 can be connected to the drain pipe 5 at an angle upwards. Since the heating element is located higher than the inlet, the odor-proof bend can be formed at the front end of the inlet.

[0027] like Figure 3 As shown, a baffle plate 7 is installed inside the drain pipe 5 at the junction of the heating element drain pipe 6 and the drain pipe 5. At the junction of the two pipes, the baffle plate 7 divides the drain pipe 5 into two isolated sub-channels. One sub-channel is connected to the water collection box 3 to drain accumulated water from the collection box, and the other sub-channel is connected to the heating element drain pipe 6 to guide the discharge of wastewater from the heating element. This design achieves physical isolation between the two water flows with a simple structure, effectively solving the problem of crossflow at the drain outlet of the water collection box, thereby significantly improving the reliability of the water dispenser.

[0028] like Figure 4As shown, the upper end of the baffle plate 7 is fixed to the inner wall of the drain pipe 5, specifically located on the upper side of the hot water tank drain pipe 6, and transitions to a position facing the hot water tank drain pipe through a bending structure. Preferably, the baffle plate 7 includes a baffle plate inclined plate 7-1 and a baffle plate vertical plate 7-2, which are integrally formed and are rigid partitions. The upper end and side of the baffle plate inclined plate 7-1 are fixed to the inner wall of the drain pipe 5, and the lower end extends into the drain pipe 5 and connects with the baffle plate vertical plate 7-2 to form an inclined guide surface. The baffle plate vertical plate 7-2 extends along the axial direction of the drain pipe and, together with the baffle plate inclined plate 7-1, divides the intersection of the drain pipe 5 into two independent sub-channels, namely the first sub-channel A connected to the water collection box 3 and the second sub-channel B connected to the hot water tank drain pipe 6.

[0029] When the water collected in the collection box 4 enters the drain pipe 5 through the drain outlet 3-3, the water flows along the first sub-channel A. The inclined surface of the baffle plate 7-1 guides the water flow downstream, while simultaneously preventing it from entering the second sub-channel B (the direction of the heat exchanger's drainage). When the heat exchanger's drain pipe 6 discharges wastewater, the water flows along the second sub-channel B into the drain pipe 5. The baffle plate 7-2 prevents the water flow from flowing towards the first sub-channel A (the direction of the collection box), ensuring that the wastewater is discharged directly. The baffle plate 7-1 and the baffle plate 7-2 work together to completely isolate the two water flows at their confluence, preventing crossflow or backflow.

[0030] The baffle plate 7 is preferably made of high-temperature and corrosion-resistant PP material, and is fixed to the inner wall of the drain pipe through injection molding, requiring no additional fasteners. The baffle plate 7 has no moving parts, and there is no risk of clogging or failure with long-term use.

[0031] The above embodiments are merely typical implementations of this utility model and are not intended to limit the scope of this utility model. All equivalent substitutions or improvements made within the scope of the claims of this utility model are protected by this utility model.
