Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and more specifically to a high-efficiency filtration device for commercial direct drinking water machines. Background Technology

[0002] A direct drinking water machine is a device that purifies municipal tap water into drinking water, or simultaneously heats, cools, and dispenses the purified water using electricity. It is a water purifier that filters and purifies municipal raw water (using physical methods) to produce drinking water for direct consumption. Also known as a point-of-use water purifier, direct drinking water machines can be categorized based on their usage and design: countertop, floor-standing, wall-mounted, built-in, commercial, and automatic water vending machines. Commercial direct drinking water machines are large-scale water purification devices specifically designed for public places.

[0003] Existing water purifiers have a heating function, which allows people to get hot water at any time by using the built-in heating device. However, sometimes when people urgently need to drink water, the hot water is too hot, and it is not convenient to control the temperature by adding cold water, so they cannot drink warm water directly. Secondly, tap water contains many different impurities, which requires multiple filtrations to completely purify the water quality. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-efficiency filtration device for commercial direct drinking water machines to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a high-efficiency filtration device for a commercial direct drinking water machine, comprising a device body and a filtration mechanism.

The filtration mechanism includes a water inlet pipe, a primary filter is fixedly connected to the other side of the water inlet pipe, a secondary filter is fixedly connected to the other side of the primary filter, a tertiary filter is fixedly connected to the other side of the secondary filter, and a water outlet pipe is fixedly connected to the bottom of the other side of the tertiary filter. A heat exchanger is movably connected to the outside of the water outlet pipe.

[0006] Furthermore, the primary filter uses a PP cotton filter element, the secondary filter uses a granular activated carbon filter element, and the tertiary filter uses a reverse osmosis membrane filter element or an ultrafiltration membrane filter element.

[0007] Furthermore, the main body of the device includes a device housing, a control panel is fixedly connected to the top of the center of the front of the device housing, a temperature display screen is fixedly connected to the top of the front of the control panel, and control buttons are fixedly connected to the bottom of the front of the control panel.

[0008] Furthermore, a warm water outlet is fixedly connected to one side of the top of the front center of the device housing, a hot water outlet is fixedly connected to the other side of the top of the front center of the device housing, and a door panel is movably connected to the bottom of the front of the device housing.

[0009] Furthermore, the heating mechanism includes a heater, with an inner tank outlet fixedly connected to the top of the heater, an inner tank inlet fixedly connected to the middle of one side of the heater, and a drain outlet fixedly connected to the bottom of the heater.

[0010] Furthermore, a hot water connection pipe is fixedly connected to the top of the water outlet of the inner tank, a warm water connection pipe is fixedly connected to one side of the hot water connection pipe, and a heat exchanger is movably connected to the outside of the warm water connection pipe.

[0011] Furthermore, the heater has a structure with an internal food-grade stainless steel pressureless inner liner and uses inner liner heating. The top of the heater is equipped with a top temperature probe, and the bottom of the heater is equipped with a bottom temperature probe.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model has a filtration mechanism. Tap water enters the primary filter through the inlet pipe and is filtered by the PP cotton filter element to remove large particles such as mud, sand, and rust. Then it enters the secondary filter and is filtered by the activated carbon filter element to remove discoloration, odor, residual chlorine, and some organic matter. Finally, it enters the tertiary filter element to remove bacteria, viruses, etc. This multi-stage fine filtration is beneficial to improve the filtration effect.

[0014] 2. This utility model has a heating mechanism. Filtered water enters the inner tank of the heater through the inner tank inlet for heating. The heated water is then released from the hot water outlet through the inner tank outlet and the hot water connection pipe. When the warm water outlet is pressed, the hot water is cooled down by the heat exchanger through the warm water connection pipe and then released as warm water. This allows for the convenient release of both warm and hot water for drinking at any time, improving efficiency. Attached Figure Description

A top temperature probe is provided at the top of the heater 301 and a bottom temperature probe is provided at the bottom of the heater 301.

[0028] The working principle of this utility model:

[0029] Tap water enters the primary filter 202 through the inlet pipe 201, where it is filtered by a PP cotton filter element to remove large particles such as sediment and rust. It then enters the secondary filter 203, where an activated carbon filter element removes discoloration, odors, residual chlorine, and some organic matter. Finally, it enters the tertiary filter 204, where a filter element removes bacteria and viruses. This multi-stage filtration process enhances the filtration effect. The filtered water then enters the inner tank of the heater 301 through the outlet pipe 205, heat exchanger 206, and inner tank inlet 303 for heating. The heated water then exits through the inner tank outlet 302 and hot water connection pipe 305 from the hot water outlet 106. When the warm water outlet 105 is activated, the hot water from the warm water connection pipe 306 is cooled by the heat exchanger 206 and released as warm water. Simultaneously, the filtered water absorbs heat in the heat exchanger 206, increasing its temperature and entering the heater 301 as warm water. This process facilitates heat exchange and energy saving, allowing for the immediate release of both warm and hot water for drinking, thus improving efficiency.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
