[0003] The liquid heating device is a popular electric appliance, which heats the water body to boiling by the built-in heating body for the user to use. The boiling water body temperature can reach up to 100℃, and the user cannot directly drink or use (adjust milk, tea, etc.) the water body with such high temperature. The user generally needs to wait for a long time for the water body temperature to drop to the applicable temperature before drinking or using, which greatly reduces the user experience.

[0004] Therefore, most of the market vendors generally use air cooling to reduce the temperature, that is, a high-power fan is added inside the liquid heater to directly cool the heating inner container.

In addition, some vendors also use a small-power fan and set a cooling air duct directly into the heating inner container to cool the liquid in the inner container. In order to avoid water vapor reaching the fan module through the cooling air duct and damaging the fan module, a water blocking rib needs to be set in the cooling air duct.

DETAILED DESCRIPTION

[0032] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0033] In the description of the present application, it should be noted that the directions or position relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the directions or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the present application in that the indicated modules or elements must have a specific direction, be constructed in a specific direction and be operated.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0035] Referring to Figures 1-5 The present application provides a liquid heater capable of rapidly cooling liquid, comprising a heating inner container 1, a water outlet assembly and a cooling assembly, the heating inner container 1 is used for storing and heating liquid; the water outlet assembly comprises a first water pump 2, a first connecting pipe 3 and a water outlet pipe 4, the water inlet end of the first water pump 2 is communicated with the heating inner container 1, the water outlet end of the first water pump 2 is communicated with the water outlet pipe 4 through the first connecting pipe 3; the cooling assembly comprises a second water pump 5, a second connecting pipe 7 and a cold water tank 6, the water inlet end of the second water pump 5 is communicated with the cold water tank 6, and the water outlet end of the second water pump 5 is communicated with the cold water tank 6 through the second connecting pipe 7 to form a closed loop water circuit.

[0036] Among them, the second connecting pipe 7 is at least partially sleeved outside the first connecting pipe 3, and under the action of the second water pump 5, the cold water in the cold water tank 6 can enter the second connecting pipe 7 to exchange heat with the high-temperature liquid in the first connecting pipe 3, thereby realizing rapid cooling of the high-temperature liquid.

[0037] Thus, when the user presses the water outlet button, the first water pump 2 is started at this time and the high-temperature liquid in the heating inner container 1 is pumped out to flow into the first connecting pipe 3, and at the same time, the second water pump 5 in the cooling assembly is started and the cold water in the cold water tank 6 is pumped into the second connecting pipe 7, the cold water flowing into the second connecting pipe 7 can exchange heat with the high-temperature liquid in the first connecting pipe 3 to achieve rapid cooling of the high-temperature liquid, and then the cooled liquid can flow out through the water outlet pipe 4 for the user to drink directly, thereby greatly shortening the user's waiting time for cooling and improving the user's experience.

[0038] Therefore, compared with the traditional cooling method of air cooling, the liquid heater has the advantages of small noise, simple structure, low cost, good cooling effect and higher practicability.

[0039] Further referring to Figures 3-4 The first connecting pipe 3 comprises a first coil pipe portion 301 arranged in a spiral layering manner, and the second connecting pipe 7 comprises a second coil pipe portion 701 arranged in a spiral layering manner, and the second coil pipe portion 701 is sleeved outside the first coil pipe portion 301.

[0040] Thus, by arranging the coil pipe portions in a spiral layering manner, the flow path of the liquid in the pipeline is prolonged, so that the high-temperature liquid in the first coil pipe portion 301 can be fully exchanged with the low-temperature water in the second coil pipe portion 701, thereby greatly improving the heat exchange efficiency; in addition, prolonging the flow path of the liquid in the pipeline can further reduce the temperature of the high-temperature liquid.

[0041] Referring to Figure 1 The liquid heater further comprises an inner container shell 10 arranged at the outer circumferential portion of the heating inner container 1, and the first coil pipe portion 301 and the second coil pipe portion 701 are wound on the outer side wall of the inner container shell 10; thus, by arranging the first coil pipe portion 301 and the second coil pipe portion 701 on the inner container shell 10, the heat exchange efficiency can be affected by the high temperature of the heating inner container 1.

[0042] Further referring to Figures 1-4 The first connecting pipe 3 further comprises a first joint portion 302 and a second joint portion 303 which are separately arranged at both ends of the first coil pipe portion 301 and are in communication with the first coil pipe portion 301, one end of the first joint portion 302 is in communication with the water outlet end of the first water pump 2 through a pipeline, and one end of the second joint portion 303 is in communication with the water inlet end of the water outlet pipe 4 through a pipeline. In addition, the water outlet assembly further comprises a first downcomer 8 which is arranged in the bottom of the heating inner container 1 and is in communication with the heating inner container 1, and the other end of the first downcomer 8 is in communication with the water inlet end of the first water pump 2.

[0043] Thus, when the first water pump 2 is started, the high-temperature liquid in the inner container 1 can flow into the first water pump 2 under the action of the first water pump 2, then flow out through the first joint part 302, the first coil part 301, the second joint part 303 and the water outlet pipe 4 in sequence for the user to drink.

[0044] Further, the second connecting pipe 7 further comprises a third joint part 702 and a fourth joint part 703 which are respectively arranged at two ends of the second coil part 701 and communicate with the second coil part 701, one end of the third joint part 702 communicates with the water outlet end of the second water pump 5 through a pipe, and one end of the fourth joint part 703 communicates with the water inlet end of the cold water tank 6 through a pipe. In addition, the cooling assembly further comprises a second water inlet pipe 9, one end of the second water inlet pipe 9 communicates with the water outlet end of the cold water tank 6, and the other end of the second water inlet pipe 9 communicates with the water inlet end of the second water pump 5.

[0045] Thus, when the second water pump 5 is started, the low-temperature water in the cold water tank 6 can flow into the second water pump 5 under the action of the second water pump 5, then flow back to the cold water tank 6 through the third joint part 702, the second coil part 701 and the fourth joint part 703 in sequence.

[0046] The cold water tank 6 is located directly below the water outlet of the water outlet pipe 4, and the cold water tank 6 comprises a tank body 601 and a cover plate 602 arranged on the tank body 601, and a plurality of grid holes 6021 are formed in the cover plate 602.

[0047] Thus, by locating the cold water tank 6 below the water outlet end of the water outlet pipe 4, the excess or residual liquid generated during use can flow into the cold water tank 6, and the collected residual liquid can then be used to cool the high-temperature liquid, thereby improving the utilization rate of residual water.

[0048] It should be noted that when used for the first time, the user needs to manually add low-temperature water to the cold water tank 6, and then the low-temperature water can flow and exchange heat with the high-temperature liquid under the action of the second water pump 5. Considering that the user will not use a large amount of hot water at one time, when the low-temperature water in the cold water tank 6 is changed into high-temperature water through heat exchange and flows back to the cold water tank 6, the high-temperature water in the cold water tank 6 has dropped to room temperature by the time the user needs to drink water again, so the room temperature water in the cold water tank 6 can exchange heat with the high-temperature liquid again, and so on.

[0049] When the user needs a large amount of hot water at one time, a refrigeration module can be arranged in the cold water tank 6, which can cool the water in the cold water tank 6, thereby ensuring that the water in the cold water tank 6 is always at a low temperature, and thereby ensuring the heat exchange effect with the high-temperature liquid. This is not limited.

[0050] Referring toFigure 5 The heating inner container 1 comprises an inner container body 101 and an inner container bottom 102, which are connected to each other and internally surround a liquid storage cavity for storing liquid. In addition, a heating module is further included, which comprises a heat transfer plate 103 and a heating pipe 104 arranged at the bottom of the heat transfer plate 103, and the heat transfer plate 103 is attached to the inner container bottom 102 to heat the liquid in the liquid storage cavity.
