DETAILED DESCRIPTION

[0030] 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.
[0031] The present invention will now be described in further detail with reference to the accompanying drawings.
[0032] like Figure 1 , Figure 2 The heating assembly shown includes a main body, a heat exchanger 100, and a tank 200. The heat exchanger 100 is assembled into the main body and has a first channel 01 for water to be heated and a second channel 02 for heat exchange medium to flow through. The first channel 01 and the second channel 02 are not connected, and heat can be transferred between the first channel 01 and the second channel 02. The tank 200 is disposed in the main body and includes at least two heat tanks 21 connected in series. The tank 200 is composed of multiple heat tanks 21 connected in series and combined. It is used to hold the heat exchange medium and store heat through the heat exchange medium. Along the flow direction of the heat exchange medium, at least one of the heat tanks 21 located at the front is provided with a heating device inside, which is used to heat the heat exchange medium inside the heat tank 21.
[0033] See also Figure 1To understand, the heating device further comprises a flow meter for detecting the flow of the water body in the first channel 01 and a control module for starting the heating device when the flow of the water body in the first channel 01 is greater than a set value, the measuring end of the flow meter is arranged in the first channel 01, and the control module is electrically connected with the heating device. In actual use, the flow meter records the total amount of water discharged by the user, and only when the user discharges more than the set value of water, the control module will control the heating device to heat the heat exchange medium in the heat tank 21. Therefore, when the user discharges a small amount of water, the heat exchange medium cooled by heat exchange will first flow into the front heat tank 21, thereby only causing the temperature of the heat exchange medium in the front heat tank 21 to decrease, and the high-temperature water in the front heat tank 21 flows into the rear heat tank 21, so that the temperature of the heat exchange medium in the rear heat tank 21 can still be maintained at a high temperature. At this time, the heating device does not need to be started to heat the heat exchange medium, and the heat exchanger 100 can still obtain the high-temperature heat exchange medium in the rear heat tank 21, thereby ensuring the heating effect of the heat exchanger 100.
[0034] Through the above process, it can be understood that when the user's water discharge amount is small and does not exceed the set value of the flow meter, since the rear heat tank 21 still stores the heat exchange medium in a high-temperature state, the control module will not start the heating device, thereby ensuring the heating effect while avoiding the problem of frequent starting of the heating device inside the heat pipe.
[0035] The technical details of each component will be introduced one by one below.
[0036] In some embodiments, as shown in Figure 2 , Figure 3 The heat tank 21 is vertically arranged relative to the bottom of the main body, and the top and bottom of the heat tank 21 are respectively provided with a flow outlet 04 and a flow inlet 03. In the actual use, the heat tank 21 is vertically arranged, and the heat exchange medium in the heat tank 21 will appear stratification due to the difference in temperature, and the low-temperature heat exchange medium will be at the bottom of the heat tank 21, and the high-temperature heat exchange medium will be at the top of the heat tank 21. Through the above design, the convection of the liquid in the heat tank 21 can be slowed down, thereby enabling the heat tank 21 to output more high-temperature heat exchange medium and improving the heating effect of the heating assembly.
[0037] In some embodiments, as shown in Figure 3 , Figure 4As shown, the heat tank 21 has a heat storage chamber 05 for storing the heat exchange medium. The heat tank 21 also has a baffle plate 211, which is connected to the inner wall of the heat storage chamber 05 and is spaced apart from the inlet 03 on the side closest to the heat storage chamber 05. In actual use, the heat exchange medium is at a low temperature when it flows into the heat storage chamber 05 through the inlet 03, and the flow is relatively concentrated, which causes a significant impact on the overall heat exchange medium inside the heat storage chamber 05. This results in the high-temperature heat exchange medium inside the heat storage chamber 05 mixing with the newly flowing low-temperature heat exchange medium, leading to a rapid drop in the water temperature inside the heat tank 21. The baffle plate 211 can block and disperse the impact of the water flow when the heat exchange medium in the low temperature state flows into the heat storage cavity 05, which greatly reduces the disturbance of the liquid inside the heat storage cavity 05 when the water flows back into the heat storage cavity 05. This makes it less likely to disrupt the stratification state of the high and low temperature heat exchange medium inside the heat storage cavity 05, and allows the heat tank 21 to output a heat exchange medium with a higher temperature to the heat exchanger 100 for a longer period of time.
[0038] In some implementations, such as Figure 1 As shown, the tank 200 is provided with an inlet 06 and an outlet 07, which are respectively connected to the two ends of the second channel 02 to form a heat exchange circulation water path 08 for supplying heat exchange medium. The heating assembly also includes a circulation pump 300 for driving the flow of heat exchange medium, which is located in the heat exchange circulation water path 08. The circulation pump 300 can pump the heat exchange medium at the top of the heat tank 21 into the heat exchanger 100, and then pump the cooled heat exchange medium into the bottom of the heat tank 21. In actual use, the internal temperatures of multiple heat tanks 21 may differ. The circulation pump 300 drives the heat exchange medium to circulate between two heat tanks 21, thus allowing the heating device to be installed in only one heat tank 21 to raise the temperature of the heat exchange medium in all heat tanks 21 to a high temperature.
[0039] In some embodiments, at least two heating tanks 21 are fused together to form a whole having at least two chambers for housing the heat exchange medium, and a heat insulation structure is provided between adjacent chambers. This design makes the heating assembly more integral and easier to assemble.
[0040] Based on the above structure, the tank 200 is vertically arranged relative to the bottom of the main body. Along the flow direction of the heat exchange medium, the bottom of the previous chamber is connected to the top of the next chamber. This design can greatly reduce the convection effect of the heat exchange medium inside each chamber, so as to ensure that the heat exchanger 100 can obtain a heat exchange medium with a higher temperature for a longer time, thus ensuring the heating efficiency of the heating component.
[0041] In some embodiments, each hot tank 21 is provided with a heating device, which can make the heat exchange medium inside each hot tank 21 reach the highest temperature more quickly.
[0042] In some embodiments, as shown in Figure 4 , Figure 5 The heat exchanger 100 includes an inner tube 11 and an outer tube 12, and the outer tube 12 is sleeved outside the inner tube 11 to form a double-layer sleeve structure.
[0043] The lumen of the inner tube 11 is the first channel 01, and the gap between the outer wall of the inner tube 11 and the inner wall of the outer tube 12 is the second channel 02; or,
[0044] The lumen of the inner tube 11 is the second channel 02, and the gap is the first channel 01.
[0045] Preferably, the lumen of the inner tube 11 is the first channel 01 for flowing the water body that needs to be heated, and the gap is the second channel 02 for flowing the heat exchange medium. In this way, the water body that needs to be heated is in a state of being surrounded by the heat exchange medium in terms of spatial distribution, and the heat is not easily lost, and thus it is more easily and quickly heated to a higher temperature. The specific analysis is shown in Figure 6 Figure 6 The arrow indicates the heat transfer direction):
[0046] It can be understood that if the heat is transferred from the gap to the lumen of the inner tube 11, the range of the water body that needs to be transferred by the heat gradually decreases, and if the heat is transferred from the lumen of the inner tube 11 to the gap, the range of the water body that needs to be transferred by the heat gradually increases. By comparing the two, it can be understood that the heat transfer mode of the former makes it easier for heat to accumulate, which helps to efficiently exchange heat.
[0047] In some embodiments, as shown in Figure 5 The thermal conductivity of the inner tube 11 is greater than that of the outer tube 12. Specifically, the inner tube 11 can be made of a metal with good thermal conductivity, such as copper, aluminum, etc., which can greatly improve the heat exchange rate between the heat exchange medium and the water body that needs to be heated. The outer tube 12 can be made of a heat-insulating material, which can reduce the rate of heat loss of the heat exchange medium to the external environment, so that the heat of the heat exchange medium can be transferred to the water body that needs to be heated as much as possible.
[0048] Please refer to Figure 1 The application further provides a water supply device, which comprises a filter core 101, the heating assembly, the instant heating assembly 103 and a water outlet faucet 102.
[0049] The water supply device adopts the heating assembly, so that in the use scenario of taking water in a small amount and at a high frequency, the heating effect can be ensured, and the problem of frequently starting the heating device to heat the heat exchange medium in the heat tank 21 can be avoided.
[0050] In the description of the present application, it should be further explained that, unless otherwise specified and limited, the terms "arrange", "mount", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0051] It should be noted that in this paper, such as first and second relationship terms are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the term "include", "contain" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent in such process, method, article or equipment. Without more limitations, the element defined by the sentence "including a" does not exclude the presence of other identical elements in the process, method, article or equipment including the element.
[0052] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
