Description

Technical Field

[0001] This utility model relates to the technical field of water purifiers, and in particular to a water purifier with a heating device. Background Technology

[0002] With the continuous improvement of people's living standards, water purifiers have become a common household product due to their excellent water purification function and moderate cost. However, most water purifiers on the market only purify cold water. If hot water is needed, the filtered cold water must be heated using an external electric kettle or water dispenser, which is not only cumbersome but also inconvenient. To reduce the number of products needed and improve ease of use, water purifiers with heating devices have been developed. For example, utility model patent CN206901908U discloses a water purifier with a pressure tank and heating element. Cold water enters through the inlet, is filtered through multiple filter elements, and then enters the pressure tank. A T-junction connects the post-activated carbon filter element and the pressure tank. One T-junction is connected to a second inlet solenoid valve, a water tank, and a heating module, while the other T-junction is connected to a purified water faucet. Because of the integrated heating module, purified warm water can be obtained through the purified water faucet, and purified hot or warm water can be obtained through the second inlet solenoid valve, water tank, and heating module. However, the heating module inside the water purifier will inevitably dissipate heat, causing the internal temperature of the water purifier to rise. If used for a long time, this may affect the safety of the water filter and connecting pipes. Utility Model Content

[0003] To address the shortcomings and deficiencies of existing technologies and reduce heat accumulation inside water purifiers, this utility model provides a water purifier with a heating device.

It is understood that when an element or layer is referred to as being “on,” “connected to,” or “coupled to” another element or layer, it can be directly on, directly connected to, or coupled to the other element or layer, or there may be an intervening element or layer.

[0020] like Figures 1-3 As shown, a water purifier with a heating device 5 is provided, including a main body 1. The main body 1 is square-shaped and includes an upper plate 11, a lower plate 12, a left plate 13, and a right plate 14. A web plate 15 is also vertically arranged inside the main body 1, which divides the inner cavity of the main body 1 into a front cavity 101 and a rear cavity 102. It also includes a filter element 2 and a booster pump 3. The filter element 2 is disposed in the front cavity 101, and the booster pump 3 is disposed on the right side of the rear cavity 102. The booster pump 3 and the filter element 2 are connected together through a first cold water pipe 41, thereby supplying external cold water to the filter element 2 for filtration. The device 5 is also included. The heating device 5 is located in the middle left area of ​​the rear cavity 102. The heating device 5 includes a heating tube 51 arranged on the left and right and a water pump 52. The water pump 52 is connected to the filter element 2 through a second cold water pipe 42. The heating tube 51 is connected to the water pump 52 through a third cold water pipe 43. The water pump 52 can draw filtered water from the filter element 2 to the heating tube 51. The heating tube 51 is arranged between the water pump 52 and the booster pump 3. The first cold water pipe 41, the second cold water pipe 42 and the third cold water pipe 43 are arranged around the right, left, upper and lower sides of the heating tube 51.

[0021] To facilitate the installation of the heating device 5, the heating device 5 further includes a bracket 53. The bracket 53 includes a base plate 531 and a first upright plate 532 vertically arranged on the base plate 531. The heating element 51 and the water pump 52 are connected to the base plate 531 of the bracket 53, and the first upright plate 532 is positioned between the heating element 51 and the water pump 52. By setting up the bracket 53, not only is an installation foundation provided for the heating element 51 and the water pump 52, allowing them to be installed onto the bracket 53 first, but the heating device 5 is then connected to the main body 1 via fastening screws, simplifying the installation of the heating device 5. Furthermore, the first upright plate 532 reduces heat transfer towards the water pump 52.

[0022] Furthermore, the heating device 5 also includes a control circuit board 54, which is connected to the base plate 531 and arranged between the first upright plate 532 and the water pump 52. The bracket 53 also includes a second upright plate 533, which is arranged between the control circuit board 54 and the water pump 52.

[0023] Furthermore, the heating device 5 also includes a heat-insulating reflector 55, which is connected to the base plate 531 of the bracket 53 and is spaced outwards from the heating tube 51. By setting the heat-insulating reflector 55, heat loss can be reduced and the heat utilization rate of the heating tube 51 can be improved.

[0024] To reduce heat accumulation in the rear cavity 102, several air vents 16 are provided on the web 15. These vents 16 are arranged along the edge of the web 15 and connect the front cavity 101 and the rear cavity 102. This allows some heat from the rear cavity 102 to enter the front cavity 101 through the air vents 16. Furthermore, the arrangement of the air vents 16 along the edge of the web 15 allows heat emitted from the center to diffuse outwards. Since some heat has already been absorbed and carried away by the cold water pipes surrounding the heating element 51, the heat emitted to the air vents 16 is significantly reduced. When the heat enters the front cavity 101 through the air vents 16 and mixes with the relatively cool air in the front cavity 101, although this slightly raises the air temperature in the front cavity 101, it does not affect the normal operation of the filter element 2.

[0025] Furthermore, an air passage 17 is also included on one side of the front cavity 101. The air passage 17 is connected to the air passage 16, and the number of air passages 17 matches the number of air passages 16.

[0026] Furthermore, a plurality of bottom through holes 120 are provided on the lower plate 12. By providing the bottom through holes 120, not only can some heat be dissipated, but water in the front cavity 101 can also be drained.

[0027] Furthermore, it also includes a front cover plate 18 and a rear cover plate 19. The front cover plate 18 is detachably connected to the front opening of the main body 1, and the rear cover plate 19 is detachably connected to the rear opening of the main body 1. It also includes a heat insulation layer, which is arranged between the rear cover plate 19 and the heating device 5.

[0028] To produce purified water, the booster pump 3 delivers cold water at a certain pressure to the filter element 2 (generally an RO reverse osmosis filter element 2). The purified water produced after filtration is stored in the filter element 2. The water purifier may also include a storage tank to store a portion of the purified water produced by the filter element 2. The water pump 52 draws purified water from the filter element 2 or the storage tank and delivers it to the heating element 51. To ensure sufficient water in the filter element 2 or the storage tank, a pressure switch 6 is included. The pressure switch 6 is connected to the second cold water pipe 42 to detect the water pressure in the filter element 2 or the storage tank. When the pressure in the pipeline is lower than a preset value, the pressure switch 6 will activate or send a signal, thereby activating the booster pump 3.

[0029] Compared with the prior art, this utility model has significant advantages and beneficial effects: First, by setting the web plate 15 to divide the inner cavity of the main body 1 into a front cavity 101 and a rear cavity 102, and placing the filter element 2 and the heating device 5 separately in the front and rear cavities, since the filter material in some filter elements 2 has low heat resistance, this separate arrangement can effectively reduce the impact of the heat generated by the heating device 5 on the filter material in the filter element 2, thereby ensuring the normal operation of the filter element 2; Second, the heating device 5 is set in the middle left area of ​​the rear cavity 102, and the heating tube 51 is arranged in the pumping section. The pump 52 and the booster pump 3 are arranged together, with the first cold water pipe 41, the second cold water pipe 42 and the third cold water pipe 43 arranged around the heating tube 51. This allows cold water to be transported around the heating tube 51, so that the cold water can absorb some of the heat, which helps to reduce the impact of heat on the main body 1 and thus reduce the temperature rise of the exterior of the main body 1. Third, the air vents 16 are arranged at the edge of the web plate 15 to guide some hot air into the front cavity 101, but as far away from the filter element 2 as possible to reduce the impact on the filter element 2. This helps to improve the stability and lifespan of the water purifier product.
