Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, and specifically relates to a steam discharge pipeline for preventing heat from escaping. Background Art

[0002] A water purifier, also known as a water purifying device, a water quality purifier or a filter, is a water treatment device for deeply filtering and purifying water quality. The working principle of the water purifier is mainly based on the sieve filtration principle, that is, using the pressure difference and filtering materials (such as filter elements, membranes, etc.) to screen and remove impurities in water. Conventional water purifiers also have a heating function. By heating the filtered water, water at different temperatures can be discharged when outputting water, which is convenient for people to use.

[0003] For a water purifier with a heating function, it generally has a built-in water tank and a heating tank inside. The filtered purified water is stored in the built-in water tank, and then a water pipe is arranged between the built-in water tank and the heating tank. By using the height difference between the built-in water tank and the heating tank, the purified water in the built-in water tank can be replenished into the heating tank. When the heating tank heats the purified water, a large amount of steam will be generated, increasing the internal air pressure of the heating tank. However, the conventional heating tank is directly connected to the built-in water tank through a steam pipe to discharge the steam and balance the internal air pressure of the heating tank. However, a large amount of steam entering the inside of the built-in water tank will cause the water temperature inside the built-in water tank to rise, affecting the user experience, so further improvement can be made.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 - 6 , a steam discharge pipeline for preventing heat leakage, including a built-in water tank 1 and a heating tank 2. The heating tank 2 is located below the built-in water tank 1. A make-up water pipe 3 is connected between the built-in water tank 1 and the heating tank 2. Using the height difference, the purified water inside the built-in water tank 1 is supplemented into the heating tank 2. The top of the built-in water tank 1 is connected with a water injection pipe 4, and the filtered purified water is injected into the interior of the built-in water tank 1 through the water injection pipe 4. The bottom right of the built-in water tank 1 is connected with a cold water pipe 5, and the relatively low-temperature purified water inside the built-in water tank 1 is discharged through the cold water pipe 5.

[0026] A heater 6 is fixedly penetrated through the center of the top of the heating tank 2. The top end of the make-up water pipe 3 is connected to the bottom of the built-in water tank 1, and the bottom end of the make-up water pipe 3 is connected to the bottom of the side of the heating tank 2, and the bottom end of the make-up water pipe 3 is lower than the bottom end of the heater 6. Prevent the steam generated after the heater 6 heats the purified water inside the heating tank 2 from flowing back into the interior of the built-in water tank 1 through the make-up water pipe 3. The top of the heating tank 2 is connected with a hot water pipe 7 and a steam pipe 8. The hot water pipe 7 is fixedly penetrated through the top end of the heating tank 2, and the bottom end of the hot water pipe 7 extends to the middle of the heating tank 2. The hot water pipe 7 is connected with a micro water pump, not shown in the figure. The hot water pipe 7 is used to discharge the hot water inside the heating tank 2. The other end of the steam pipe 8 is connected with a cooling assembly 9. The top of the cooling assembly 9 is provided with an exhaust end, and the bottom is provided with a drainage end. The drainage end is connected to the built-in water tank 1, and the exhaust end is connected with a heat exchange assembly 10. The heat exchange assembly 10 is sleeved outside the steam pipe 8.

[0027] The cooling assembly 9 includes a cooling box 901. The top end of the steam pipe 8 is connected to the side surface of the cooling box 901 and is in communication with the cooling box 901. The cooling box 901 is circular and flat, enabling the cooling box 901 to be in full contact with the external air. Thus, after the steam enters the interior of the cooling box 901 through the steam pipe 8, the cooling box 901 dissipates heat from the steam, accelerating the condensation of the moisture in the steam. A return pipe 902 is fixedly installed at the center of the top wall of the cooling box 901. The return pipe 902 penetrates through the bottom of the cooling box 901 and is connected to the top of the built-in water tank 1. An exhaust pipe 903 is fixedly installed through the center of the top of the cooling box 901. The exhaust pipe 903 extends into the interior of the return pipe 902. The return pipe 902 serves as the drainage end, and the exhaust pipe 903 serves as the exhaust end.

[0028] A spiral plate 904 is fixedly installed between the inner side wall of the cooling box 901 and the outer side wall of the return pipe 902. An arc plate 905 is fixedly installed between the inner side wall of the cooling box 901 and the outer wall of the second circle of the return pipe 902 from the outside to the inside. The spiral plate 904 and the arc plate 905 enclose a spiral flow channel inside the cooling box 901. The steam pipe 8 is in communication with the outer end of the spiral flow channel. The return pipe 902 is provided with a diversion port 907 on the circumferential surface inside the cooling box 901. The return pipe 902 is in communication with the inner end of the spiral flow channel through the diversion port 907. Thus, the steam enters the outer end of the spiral flow channel through the steam pipe 8, then flows along the spiral flow channel, and then passes through the diversion port 907 and enters the interior of the return pipe 902. Through the setting of the spiral flow channel, the flow time of the steam inside the cooling box 901 is prolonged, ensuring the cooling effect on the steam.

[0029] A spiral plate 906 is fixedly installed between the inner wall of the return pipe 902 and the outer wall of the exhaust pipe 903. The spiral plate 906 forms a spiral flow channel inside the return pipe 902. The inner end of the spiral flow channel is in communication with the top end of the spiral flow channel through the diversion port 907. The diameter of the part of the return pipe 902 located outside the cooling box 901 gradually decreases from top to bottom. After the cooled steam enters the interior of the return pipe 902, it flows along the spiral flow channel, and under the action of centrifugal force, the condensed small droplets adhere to the inner wall of the return pipe 902 and flow along the inner wall of the return pipe 902 into the interior of the built-in water tank 1. The gaseous part of the steam enters the interior of the exhaust pipe 903 from the bottom end of the exhaust pipe 903 and then is discharged from the exhaust pipe 903.

[0030] The heat exchange assembly 10 includes a sleeve 1001. A connecting pipe 1002 is connected to the top of the sleeve 1001. The other end of the connecting pipe 1002 is connected to the exhaust pipe 903. A tail gas pipe 1003 is connected to the side of the bottom end of the sleeve 1001. The steam pipe 8 passes through the sleeve 1001 along the central axis of the sleeve 1001. Part of the gas after the steam is cooled enters the connecting pipe 1002 through the exhaust pipe 903, then enters the sleeve 1001, and finally is discharged through the tail gas pipe 1003. When the steam flows upward along the steam pipe 8 and passes through the inside of the sleeve 1001, the high-temperature steam exchanges heat with the cooled steam to pre-cool the steam inside the steam pipe 8.

[0031] Working principle: Due to the height difference, the water in the built-in water tank 1 is replenished into the inside of the heating tank 2 through the water supply pipe 3. The water in the heating tank 2 is heated by the heater 6, and the generated steam enters the inside of the cooling box 901 from the steam pipe 8 and flows along the spiral flow path. The steam is dissipated by the shell of the cooling box 901 to reduce the temperature of the steam.

[0032] After that, the steam passes through the diversion port 907 and enters the spiral flow path. Under the action of centrifugal force, the condensed droplets adhere to the inner wall of the return pipe 902 and flow into the inside of the built-in water tank 1 along the inner wall of the return pipe 902.

[0033] Part of the gas after the steam is cooled enters the connecting pipe 1002 from the exhaust pipe 903, then enters the inside of the sleeve 1001 through the connecting pipe 1002, and finally is discharged through the tail gas pipe 1003. When the high-temperature steam flows upward inside the steam pipe 8 and passes through the inside of the sleeve 1001, the high-temperature steam exchanges heat with the cooled steam to pre-cool the steam inside the steam pipe 8.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
