Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a novel liquid heater. Background Technology

[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] Liquid heating devices are common household appliances. They heat the water in the inner tank to boiling point through a heating module before supplying it to the user. The boiling water temperature can reach up to 100℃, which is too high for users to drink or use directly (for making milk, tea, etc.). Users usually need to wait a long time for the water temperature to drop to a suitable temperature before they can drink or use it, thus reducing the user experience.

[0004] To achieve rapid water cooling, some manufacturers have incorporated a heat exchanger and a cold water tank into their liquid heating devices. When water is needed, the first water pump starts, drawing hot water from the inner tank and directing it into the inner tube of the heat exchanger. Simultaneously, the second water pump starts, drawing cold water from the cold water tank into the outer tube of the heat exchanger. The cold water flowing into the outer tube exchanges heat with the hot water flowing in the inner tube, thus rapidly cooling the hot water. The cooled water can then flow out through the outlet pipe for direct drinking, significantly reducing the waiting time for cooling and improving the user experience.

[0005] However, during use, it was found that because the pipeline connecting the cold water tank and the second water pump is usually fixed, the cold water tank cannot be removed separately, which not only makes it difficult to add water, but also makes it difficult to clean, which is quite troublesome. Utility Model Content

[0006] In order to overcome the defects of the prior art, the present invention provides a novel liquid heater, which can be made into a detachable structure by setting a vertically movable water pump pipe in the cold water tank, so as to facilitate its removal for water addition or cleaning.

[0020] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] 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 this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] See Figure 1-5This utility model provides a novel liquid heater, including a housing 1, a heating inner tank 2, a heat exchanger 3, and a cold water tank 4. The housing 1 includes a square column-shaped main body 101 and a protrusion 102 located on the top front side of the main body 101. The heating inner tank 2 is located inside the main body 101, and the heat exchanger 3 is located inside the protrusion 102. The cold water tank 4 is detachably placed on the front side of the main body 101 and below the protrusion 102. The bottom of the protrusion 102 is provided with a water inlet 1021, and the cold water tank 4 is provided with a vertically movable water suction pipe 11. Additionally, a magnetic attraction structure is provided between the protrusion 102 and the water suction pipe 11. When the cold water tank 4 is placed on the front side of the main body 101 and below the protrusion 102, the magnetic attraction of the magnetic attraction structure causes the water suction pipe 11 to move upward, so that the water outlet of the water suction pipe 11 engages with the water inlet 1021 to achieve communication.

[0024] Therefore, by providing a vertically movable water suction pipe 11 inside the cold water tank 4, when the cold water tank 4 is placed on the front side of the main body 101 of the casing 1, the magnetic attraction of the magnetic structure can drive the water suction pipe 11 to move upward so that the water outlet end of the water suction pipe 11 can connect with the water inlet interface 1021 to achieve communication. Thus, through the above structural design, the cold water tank 4 can be made into a detachable structure, making it convenient to remove for adding water or cleaning.

[0025] See Figure 3 Specifically, the magnetic attraction structure includes a first magnetic ring 901 sleeved around the water inlet 1021 and a second magnetic ring 902 sleeved around the water outlet of the pump pipe 11. The magnetic poles of the first magnetic ring 901 and the second magnetic ring 902 are opposite. Thus, when the cold water tank 4 is assembled to the front of the main body 101 of the casing 1, the first magnetic ring 901 and the second magnetic ring 902 are vertically opposite each other. Under the magnetic attraction, the pump pipe 11 can be moved upward until the first magnetic ring 901 and the second magnetic ring 902 are attracted to each other. At this time, the water outlet of the pump pipe 11 is connected to the water inlet 1021.

[0026] Of course, it should be noted that in other embodiments, either the first magnetic ring 901 or the second magnetic ring 902 can be replaced with a magnetic metal ring, which can achieve the same technical effect. Therefore, this is not a limitation.

[0027] Preferably, it also includes a sealing sleeve 10 sleeved around the water outlet of the water pump 11 to form a waterproof seal. When the first magnetic ring 901 and the second magnetic ring 902 are magnetically attracted and drive the water outlet of the water pump 11 to engage with the water inlet 1021, the sealing sleeve 10 abuts against the bottom of the protrusion 102 to form a waterproof seal, thereby preventing water in the cold water tank 4 from leaking when it enters the water inlet through the water pump 11.

[0028] In this embodiment, a mounting bracket is also included, which is sleeved around the outer periphery of the sealing sleeve 10, and the second magnetic ring 902 is disposed inside the mounting bracket.

[0029] Of course, in other embodiments, the sealing sleeve 10 can also be placed inside the water inlet interface 1021, and when the water outlet end of the water pump 11 is connected to the water inlet interface 1021, the sealing sleeve 10 can abut against the water pump 11 to achieve waterproof sealing, which can also achieve the same technical effect, and is not limited here.

[0030] See also Figure 1-2 It also includes a water tray 5, which is detachably placed at the bottom front side of the main body 101, and the cold water tank 4 is placed on the water tray 5. In addition, it includes a positioning structure disposed between the cold water tank 4 and the water tray 5. The positioning structure includes a locking block 501 and a locking groove 401 that engage with each other. The locking block 501 protrudes from the water tray 5, and the locking groove 401 is formed at the bottom of the cold water tank 4. When the cold water tank 4 is placed at the front side of the main body 101 of the housing 1 until the locking block 501 and the locking groove 401 engage, the cold water tank 4 is positioned, thereby preventing the cold water tank 4 from shaking.

[0031] See Figure 2 Preferably, the height of the heat exchanger 3 is higher than the height of the highest water level in the heating water chamber. This arrangement prevents residual water from remaining in the heat exchanger 3, thus avoiding affecting the heat exchange effect.

[0032] Specifically, the heat exchanger 3 includes an outer coil 302 and an inner coil 301, with the outer coil 302 partially sleeved around the outer periphery of the inner coil 301. It also includes a first water pump 6 located within the main body and below the heating inner tank 2. The inlet of the first water pump 6 is connected to the heating inner tank 2 via a pipe, and the outlet of the first water pump 6 is connected to the inlet of the inner coil 301 via a pipe. A first water outlet 1022 is provided at the bottom of the protrusion 102, and the outlet of the inner coil 301 is connected to the first water outlet 1022 via a water outlet pipe 8.

[0033] Therefore, under the action of the first water pump 6, the hot water in the heating inner tank 2 will be drawn out and flow sequentially to the inner coil 301, the water outlet pipe 8 and the first water outlet 1022 and then flow out for the user to drink.

[0034] More specifically, it also includes a second water pump 7 installed inside the protrusion 102. The inlet end of the second water pump 7 is connected to the inlet interface 1021 through a pipe, and the outlet end of the second water pump 7 is connected to the inlet end of the outer coil 302 through a pipe. The bottom of the protrusion 102 is provided with a second outlet interface 1023. The outlet end of the outer coil 302 is connected to the second outlet interface 1023 through a pipe, and the second outlet interface 1023 is connected to the cold water tank 4.

[0035] Therefore, under the action of the second water pump 7, the cold water in the cold water tank 4 can be drawn out and flow sequentially to the outer coil 302 and the second water outlet 1023 and then flow out to re-enter the cold water tank 4.

[0036] When cold water flows into the outer coil 302, it can exchange heat with the hot water flowing through the inner coil 301 to cool the hot water, so that the temperature of the water flowing out from the first water outlet 1022 is more suitable, thus making it convenient for users to drink.

[0037] See Figure 6 A first pipe body 12 is provided between the water outlet end of the inner coil 301 and the water inlet end of the water outlet pipe 8. The first pipe body 12 includes a first three-way pipe 1201 and a first one-way valve 1202. The first three-way pipe 1201 has a first water inlet 12011, a first water outlet 12012, and a first air inlet 12013. The first water inlet 12011 is connected to the water outlet end of the inner coil 301, and the first water outlet 12012 is connected to the water inlet end of the water outlet pipe 8. The first one-way valve 1202 is located at the first air inlet 12013. Preferably, the first one-way valve 1202 is a duckbill valve.

[0038] Therefore, by setting up the first three-way pipe 1201 and using the top first air inlet 12013 to guide external air into the interior of the first three-way pipe 1201, the user can effectively avoid the siphon phenomenon when stopping water use.

[0039] See also Figure 6 A second pipe body 13 is provided between the outlet end of the second water pump 7 and the inlet end of the outer coil 302. The second pipe body 13 includes a second three-way pipe 1301 and a second one-way valve 1302. The second three-way pipe 1301 has a second inlet 13011, a second outlet 13012, and a second air inlet 13013. The second inlet 13011 is connected to the outlet end of the second water pump 7, and the second outlet 13012 is connected to the inlet end of the outer coil 302. The second one-way valve 1302 is located at the second air inlet 13013. Preferably, the second one-way valve 1302 is a duckbill valve.

[0040] Additionally, it includes a first temperature probe 14 and a second temperature probe 15. The first temperature probe 14 is inserted through the second pipe body 13 to detect the inlet water temperature of the cold water tank 4. Preferably, the first temperature probe is inserted through the second one-way valve 1302; the second temperature probe 15 is inserted through the outlet pipe 8 to detect the outlet water temperature of the outlet pipe 8.

[0041] In this embodiment, both the first temperature probe 14 and the second temperature probe 15 are NTC temperature probes.

[0042] In summary, the novel liquid heater provided by this utility model, by providing a vertically movable water suction pipe 11 inside the cold water tank 4, allows the water suction pipe 11 to move upward under the magnetic attraction of the magnetic attraction structure 9 when the cold water tank 4 is placed on the front side of the main body 101 of the casing 1, so that the water outlet of the water suction pipe 11 can be connected to the water inlet interface 1021 to achieve communication. Thus, through the above structural design, the cold water tank 4 can be made into a detachable structure, making it convenient to remove for adding water or cleaning.
