Abstract
Description
Technical Field
[0001] This utility model relates to the field of water heating technology, and in particular to a faucet with heating function and a drinking water device using the faucet. Background Technology
[0002] Existing faucets are typically used to dispense room temperature water. However, in cold winters, if users continue to use faucets to dispense cold water to wash dishes, chopsticks, and various pots and pans, their hands will be cold, and grease will easily solidify, resulting in poor cleaning effectiveness and reduced user experience. To solve this technical problem, instant hot water faucets have emerged in the existing technology, which can meet users' needs for hot water.
[0003] To achieve water heating, Chinese utility model patent ZL202122267934.X (authorization announcement number CN215891364U) discloses a faucet with heating function, which consists of a faucet body with a heating cylinder and a control arm sleeved on the upper end of the faucet body. The faucet body has a heating cylinder inside, which is composed of double-layer stainless steel tubes, sealed at both ends and hollow and evacuated. There are two heating tubes inside the heating cylinder, and water inlet and outlet pipes are respectively provided at the upper and lower ends of the heating cylinder. Temperature sensors are also provided at both ends of the heating cylinder to detect the water temperature and transmit the raw water temperature and hot water temperature to the electronic control board in real time. A thermal fuse is provided on the outer side of the heating cylinder for temperature limiting protection.
[0004] While the aforementioned faucets can heat water to meet users' hot water needs, the temperature sensor probe extends into the heating element. If the raw water in the heating element is tap water or other types of water prone to limescale buildup, the limescale from the heated water can easily adhere to the temperature sensor probe, affecting the sensor's detection results. Inaccurate temperature detection leads to inaccurate water temperature readings, failing to meet the user's desired temperature and potentially causing scalding. Therefore, further improvements to the existing technology are necessary. Utility Model Content
[0005] The first technical problem to be solved by this utility model is to provide a faucet with heating function that can accurately measure temperature, in contrast to the above-mentioned prior art.
[0006] The second technical problem to be solved by this utility model is to provide a drinking water device that uses the above-mentioned faucet.
[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a faucet with heating function, comprising:
[0008] The faucet body is hollow inside;
[0009] A chamber is located inside the faucet body, and an inlet pipe and an outlet pipe are respectively connected to the two ends of the chamber;
[0010] A heating element is disposed within the cavity; and
[0011] Temperature sensor used to detect the water temperature inside the chamber;
[0012] The feature is that: the chamber is further provided with a water-proof cavity located adjacent to the water outlet pipe and / or the water inlet pipe, the water-proof cavity has a heat-conducting cavity wall, the temperature sensor is at least two, all temperature sensors are located in the water-proof cavity, and the probe of each temperature sensor is attached to the heat-conducting cavity wall.
[0013] Preferably, the chamber is cylindrical, with an outlet at the upper end of the chamber that is in fluid communication with an outlet pipe; and an inlet at the lower end of the chamber that is in fluid communication with an inlet pipe.
[0014] To ensure more uniform temperature detection, all temperature sensors are arranged circumferentially around the outer periphery of the outlet and / or inlet.
[0015] Preferably, the chamber is provided with a partition located near the water outlet and / or water inlet. The partition divides the chamber into an upper and lower water-proof chamber and a heating chamber. The partition is made of a thermally conductive material and constitutes the aforementioned thermally conductive chamber wall. The heating element is located inside the heating chamber.
[0016] Preferably, the heating element comprises a heating layer, a heat insulation layer, and an insulating layer arranged sequentially from the inside out. The heat insulation layer prevents the heat generated by the heating layer from dissipating, thus saving energy and preventing the heat from being transferred to the faucet body and causing scalding accidents. The insulating layer is located on the outermost side of the heating element, firmly wrapping it and preventing electric shock accidents caused by leakage if the heating element is damaged.
[0017] To prevent short circuits between the heating wires, the heating layer includes two sheet-like heat transfer bodies and heating wires fixed between the two heat transfer bodies. The heating wires have a tortuous shape so that the input and output ends of the heating wires are distributed vertically on the heat transfer bodies at intervals.
[0018] To make the heating layer malleable, the heating wires and heat transfer elements are made of flexible materials so that they can be rolled up.
[0019] Preferably, the heating layer is tubular.
[0020] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a drinking water device, characterized in that: it uses a faucet with heating function as described above.
[0021] Preferably, the drinking water equipment is a water dispenser or a water purifier.
[0022] Compared with the prior art, the advantages of this utility model are as follows: Firstly, by placing the temperature sensor inside the water-proof cavity, which has a heat-conducting cavity wall, and with the probes of each temperature sensor attached to the heat-conducting cavity wall, the temperature sensor can effectively avoid the influence of external factors such as scale, improve detection accuracy, and ensure that the outlet water temperature is the temperature required by the user, effectively preventing scalding of the user due to excessive heating temperature caused by inaccurate detection. Secondly, since there are at least two temperature sensors, it can effectively avoid the abnormality of the final detection result caused by the malfunction of some temperature sensors, further improving detection accuracy.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0029] like Figures 1-5 As shown, this embodiment relates to a faucet with heating function and a drinking water device using the faucet, which includes, but is not limited to, a water dispenser or a water purifier.
[0030] The faucet with heating function in this embodiment includes a faucet body 1, a chamber 2, a heating element 4, and a temperature sensor 5. The faucet body 1 is hollow inside. The chamber 2 is located inside the faucet body 1, and the two ends of the chamber 2 are respectively connected to an inlet pipe 31 and an outlet pipe 32. The heating element 4 is located inside the chamber 2. The temperature sensor 5 is used to detect the water temperature inside the chamber 2.
[0031] The chamber 2 also includes a water-proof cavity 21 located adjacent to the water outlet pipe 32. The water-proof cavity 21 has a heat-conducting cavity wall 211. At least two temperature sensors 5 are present, all housed within the water-proof cavity 21, with the probes of each temperature sensor 5 fitted against the heat-conducting cavity wall 211. For example... Figure 3 As shown, in this embodiment, the chamber 2 is cylindrical. The upper end of the chamber 2 has a water outlet 2a, which is in fluid communication with the water outlet pipe 32. The outlet of the water outlet pipe 32 corresponds to the outlet 1a of the faucet. The lower end of the chamber 2 has a water inlet (not shown in the figure), which is in fluid communication with the water inlet pipe 31.
[0032] Similarly, a water-proof cavity (not shown in the figure) can also be set in the chamber 2 near the water inlet pipe 31. The water-proof cavity near the water inlet pipe 31 is formed in the same way as the water-proof cavity 21 set near the water outlet pipe 32. The temperature sensor in the water-proof cavity near the water inlet pipe 31 is installed in the same way as the temperature sensor in the water-proof cavity 21 set near the water outlet pipe 32. This will not be elaborated further here.
[0033] like Figure 3 As shown, in this embodiment, the chamber 2 is provided with a partition 6 located near the water outlet 2a. The partition 6 divides the chamber 2 into a water-proof chamber 21 and a heating chamber 22, which are distributed vertically. The partition 6 is made of a thermally conductive material and constitutes the aforementioned thermally conductive chamber wall 211. The heating element 4 is located inside the heating chamber 22. Figure 2 As shown, in this embodiment, there are four temperature sensors 5, all arranged circumferentially around the outer periphery of the outlet 2a. The baffle 6 in this embodiment prevents water from entering the water-proof cavity 21, thus preventing water ingress that could cause scale buildup on the temperature sensor probes and affect detection accuracy. Furthermore, the average temperature detected by all temperature sensors 5 is taken as the outlet water temperature value. Of course, abnormal data is removed before averaging to avoid significant deviations in the temperature detection results due to malfunctions in some temperature sensors 5.
[0034] like Figure 4 As shown, the heating element 4 in this embodiment is cylindrical; the heating element 4 includes a heating layer 41, a heat insulation layer 42, and an insulating layer 43 arranged sequentially from the inside to the outside. The heat insulation layer 42 and the insulating layer 43 are both made of commonly used materials in the prior art, and will not be described in detail here.
[0035] like Figure 5As shown, the heating layer 41 includes two sheet-like heat transfer elements 411 and a heating wire 412 fixed between the two heat transfer elements 411. The heating wire 412 has a tortuous shape, so that the input and output ends of the heating wire 412 are distributed vertically on the heat transfer elements 411 at intervals. In addition, both the heating wire 412 and the heat transfer elements 411 are made of flexible material; the heating wire 412 and the heat transfer elements 411 can be rolled up. In this embodiment, the heating layer 41 is tubular. In this embodiment, both sides of the heating wire 412 are in contact with the heat transfer elements 411, and the heating wire 412 and the heat transfer elements 411 can be rolled up so that they can be wrapped around the inner peripheral wall of the heating cavity 22 to heat the water in the heating cavity 22. Furthermore, because the heating wire 412 has a tortuous shape, the input and output ends of the heating wire 412 are isolated to prevent short circuits.
[0036] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
