Detailed Description

It is to be understood that the terminology used herein, the specific structural and functional details disclosed are merely representative for the purpose of describing particular embodiments, but that the utility model may be embodied in many alternate forms and should not be construed as limited to only the embodiments set forth herein.

The utility model is described in detail below with reference to the attached drawings and alternative embodiments.

As shown in fig. 1 to 3, as an embodiment of the present utility model, a waterway system may include a water inlet pipe 1, a warm water pipe 2, a refrigerating pipe 3a, a heating mechanism 4, and a main water outlet pipe 5. The water outlet of the water inlet pipeline 1 is communicated with the water inlet of the heating mechanism 4, and the water outlet of the heating mechanism 4 is selectively communicated with the water inlet of the main water outlet pipeline 5 or the warm water pipeline 2. The communicating pipe between the water outlet of the heating mechanism 4, the water inlet of the warm water pipeline 2 and the water outlet of the water inlet pipeline 1 can be provided with a heat exchange mechanism 6. The water outlet of the warm water pipeline 2 is selectively communicated with the water inlet of the main water outlet pipeline 5 or the refrigerating pipeline 3a, and the water outlet of the refrigerating pipeline 3a is selectively communicated with the main water outlet pipeline 5 or is used for being communicated with the water inlet of the ice making mechanism 7 in a use state.

According to the waterway system, the water inlet pipeline 1 supplies water to the heating mechanism 4, the heating mechanism 4 heats the water into hot water, and the hot water is respectively supplied to the refrigerating pipeline 3a, the main water outlet pipeline 5 or the ice making mechanism 7, so that zero raw water supply of the whole system is ensured, and safer drinking water or ice cubes are provided for users.

Through setting up heat transfer mechanism 6, heating mechanism 4, refrigeration pipeline 3a, wherein heating mechanism 4 heats and produces hot water, and heat transfer mechanism 6 heat transfer makes hot water cooling produce warm water, and refrigeration pipeline 3a produces the frozen water to the warm water cooling to can communicate ice making mechanism 7 and make ice to the frozen water. The hot water, the warm water and the ice water can be provided for users through the main water outlet pipeline 5, and ice cubes can be provided for users through the communication ice making mechanism 7. The waterway system can ensure zero raw water, can simultaneously provide hot water, warm water and ice water, can also provide ice cubes, has more diversified functions, and reduces mechanism settings.

By providing the heat exchange mechanism 6, the raw water of the water inlet pipeline 1 and the hot water heated by the heating mechanism 4 exchange heat in the heat exchange mechanism 6, so that the raw water is heated before heating, and the hot water is cooled to warm water. Therefore, the heating mechanism 4 can save more energy when heating raw water and the cooling and ice water preparation of the refrigerating pipeline 3a, thereby achieving the purposes of saving energy consumption and improving energy utilization rate.

For a specific arrangement of the heat exchange mechanism 6, in an alternative embodiment, the heat exchange mechanism 6 may comprise an outer tube 6a and an inner tube 6b, the inner tube 6b may be arranged in the outer tube 6 a. The pipe between the outer pipe 6a and the inner pipe 6b is a section of a communication pipe, the inner pipe 6b is a section of the water intake pipe 1, or the pipe between the outer pipe 6a and the inner pipe 6b is a section of the water intake pipe 1, and the inner pipe 6b is a section of a communication pipe.

Specifically, the water inlet of the outer tube 6a is communicated with the water inlet pipeline 1, and the water outlet of the outer tube 6a is communicated with the water inlet of the heating mechanism 4. The water inlet of the inner tube 6b is communicated with the water outlet of the heating mechanism 4, and the water outlet of the inner tube 6b is communicated with the water inlet of the warm water pipeline 2.

The inner pipe 6b is nested in the outer pipe 6a, raw water in the water inlet pipeline 1 flows into the outer pipe 6a from a water inlet of the outer pipe 6a, flows out from a water outlet of the outer pipe 6a to the heating mechanism 4 for heating, heated hot water flows into the inner pipe 6b from a water inlet of the inner pipe 6b, flows out from a water outlet of the inner pipe 6b to the warm water pipeline 2, and is supplied to the refrigerating pipeline 3a or the main water outlet pipeline 5. In this process, the heat of the hot water in the inner tube 6b is transferred to the raw water in the outer tube 6a, thereby realizing the cooling of the hot water into warm water and the heating of the raw water.

For example, after hot water at about 100 ℃ flows into the inner tube 6b, the temperature is reduced to warm water at about 45 ℃ to 55 ℃ after heat exchange with raw water; and raw water at normal temperature (for example, 27 to 29 ℃) flows into the outer tube 6a, and then is heated to about 80 ℃ after heat exchange with hot water.

Preferably, the pipeline between the outer pipe 6a and the inner pipe 6b is used as a section of the water inlet pipeline 1, and the inner pipe 6b is used as a section of the communication pipeline; the length of the inner tube 6b or the outer tube 6a is between 2m and 3.2m, and the flow ratio of the inner tube 6b or the outer tube 6a is between 0.8 and 1.2. In the heat exchange mechanism 6, through heat exchange, a preset temperature, for example, warm water reaching 45 ℃ to 55 DEG can be more precisely controlled according to the length of the inner tube 6b or the outer tube 6a or the setting of the flow ratio.

Wherein the length of the inner tube 6b or the outer tube 6a is at an appropriate length in order to save more space. The flow rate of the inner tube 6b and the flow rate of the outer tube 6a are related to the size of the cross-sectional areas of the inner tube 6b and the outer tube 6a, and also related to the flow rates of the inner tube 6b and the outer tube 6 a. Normally, the cross-sectional area determines the upper limit of the flow rate, which determines the degree of heat transfer of the heat exchange. The length of the inner tube 6b or the outer tube 6a is set to provide enough heat exchange surface area to increase heat transfer efficiency, and to realize more compact structure, and meanwhile, the flow rate ratio is limited to ensure that hot water and cold water are fully contacted in the heat exchange mechanism 6, so that efficient heat exchange is controlled.

In one embodiment, the length of the inner tube 6b or the outer tube 6a may be between 2.3m and 2.9m, and the flow ratio of the inner tube 6b and the outer tube 6a may be between 0.9 and 1.1. Wherein the inner diameter of the outer tube 6a may be between 11mm and 18mm and the inner diameter of the inner tube 6b may be between 7mm and 10mm to provide sufficient heat exchanging surface area and flow capacity, and the size range is relatively small, so that the heat exchanging mechanism 6 can be installed and arranged in a limited space without affecting heat exchanging.

In the specific implementation process, the balance transfer of heat in the heat exchange process can be realized by keeping the flow ratio of the inner tube 6b to the outer tube 6a to be close to 1:1, so that hot water and raw water are fully contacted in the heat exchange mechanism 6, high-efficiency heat exchange is realized, and the heat utilization rate is improved. At the same time, the stable flow reduces the temperature gradient between the hot water and the cold water, promotes the heat transfer and improves the performance of the heat exchange mechanism 6. Preferably, in the use state, the water flow direction of the pipeline between the outer pipe 6a and the inner pipe 6b and the water flow direction of the inner pipe 6b can be opposite, so that the heat exchange effect is better.

In one embodiment, the heat exchange mechanism 6 may have a serpentine structure, the inner tube 6b and/or the outer tube 6a may be made of stainless steel, and made of high-temperature-resistant and corrosion-resistant materials, so that the heat exchange mechanism has higher durability and reliability, higher heat conductivity, higher heat exchange efficiency, long-term stable operation of the heat exchange mechanism 6 is ensured, maintenance and replacement frequency is reduced, and operation cost is reduced. The serpentine heat exchange mechanism 6 can arrange the longer inner tube 6b or outer tube 6a length in a serpentine fashion to achieve a larger heat exchange surface area in a limited space, more efficient use of space, and smaller overall heat exchange mechanism 6 volume.
