The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] As Figure 1 , Figure 5 , Figure 6 shown, a water supply device includes a hot tank 100, a heat exchange device 200, a temperature sensing component, and a circulation pump 300. An energy storage cavity 05 for storing an energy medium is provided inside the hot tank 100. Usually, the above-mentioned energy medium is water, which is used to store heat. Refer to Figure 5 , the heat exchange device 200 is connected to the hot tank 100. A first channel 03 and a second channel 04 are arranged at intervals inside the heat exchange device 200. The first channel 03 is used for flowing the water body to be heated, and the second channel 04 is used for flowing the energy medium. The liquids flowing in the first channel 03 and the second channel 04 can exchange heat. Since the boiling points of different types of energy media are different, the energy medium can be water, oil, etc. In some embodiments, an energy medium with a boiling point higher than that of water, such as oil, is used, so that the liquid flowing through the first channel 03 can be heated to a higher temperature. Refer to Figure 5 , the second channel 04 communicates with the energy storage cavity 05 and forms a circulating hot water path for the energy medium to flow. The temperature sensing component is arranged along the pipelines of the first channel 03 and the second channel 04. During the process of the energy medium flowing along the circulating hot water path, the temperature sensing component can detect the temperature of the energy medium. Refer to Figure 5 ,Figure 6 , the circulation pump 300 is arranged in the circulating hot water path. The circulation pump 300 is connected with a first speed regulation module 700 for regulating the liquid flow rate. The first speed regulation module 700 is electrically connected with the temperature sensing component. The first speed regulation module 700 controls the circulation pump 300 to regulate the flow rate of the energy medium in the hot water supply path according to the temperature sensed by the temperature sensing component, so that the water supply device can control the temperature of the hot water output.

[0034] Specifically, for the convenience of understanding (refer to Figure 5 、 Figure 6 ), let the flow rate of the liquid in the first channel 03 be V1, and let the flow rate of the liquid in the second channel 04 be V2. The ratio of the internal liquid flow rates of the first channel 03 and the second channel 04 is W, and W = V1:V2. It can be understood that when the temperature of the energy medium in the hot water tank 100 and the temperature of the water body to be heated (the water body flowing through the first channel 03) are certain, the higher the value of W, the lower the temperature of the hot water flowing out of the water supply device. In actual use, if the temperature of the energy medium in the first channel 03 is much higher than the temperature of the required hot water, directly exchanging heat at this time will cause the temperature of the discharged hot water to be higher than the required hot water temperature; in this application, since the temperature sensing component will detect the temperatures of the liquids in the first channel 03 and the second channel 04, when the above situation occurs, the first speed regulation module 700 will control the circulation pump 300 to reduce or stop the circulation speed of the energy medium in the heat exchanger, that is, the flow rate of the liquid in the second channel 04, that is, V2 decreases, and then the value of W increases. At this time, the heat obtained by the heat exchanger decreases, so that the water supply device can discharge hot water at the required temperature. On the contrary, if the temperature of the energy medium in the first channel 03 is much lower than the temperature of the required hot water, the first speed regulation module 700 will control the circulation pump 300 to increase the circulation speed of the energy medium in the heat exchanger, that is, the flow rate of the liquid in the second channel 04, that is, V2 increases, and then the value of W decreases. At this time, the heat obtained by the heat exchanger increases, so that the water supply device can discharge hot water at the required temperature; if the temperature of the energy medium in the first channel 03 is much lower than the temperature of the required hot water, the temperature sensing component can also control the circulation pump 300 to work in advance before discharging water, so that the temperature of the energy medium inside the second channel 04 increases, and then the required temperature of hot water can be obtained during subsequent water discharge.

[0035] In summary, for the water supply device provided by this application, the temperature sensing component is used to detect the temperatures of the liquids inside the first channel 03 and the second channel 04, and transmit the temperature information to the first speed regulation module 700. The first speed regulation module 700 controls the circulation pump 300 to change the flow time and flow speed of the energy medium in the second channel 04 according to the obtained temperature information, so that the heating device can stably discharge hot water at the required temperature.

[0036] The technical details of each component will be introduced one by one below.

[0037] In some embodiments, such as Figure 5 , Figure 6 shown, the above temperature sensing component includes a first temperature sensor 101, a second temperature sensor 102, and a third temperature sensor 103. The first temperature sensor 101 and the second temperature sensor 102 are respectively arranged at the water inlet end and the water outlet end of the first channel 03 pipeline, and the third sensor is arranged at the water outlet end of the second channel 04 pipeline. The first temperature sensor 101 is used to detect the initial temperature of the water body flowing into the heat exchanger from the filter element 1100, the second temperature sensor 102 is used to detect the temperature of the water body after being heated by the heat exchanger, and the third sensor is used to detect the temperature of the energy medium flowing out from the inside of the second channel 04. The first speed regulation module 700 controls the flow rate of the energy medium in the second channel 04 by controlling the circulation pump 300 according to the water temperature information and the required temperature information detected by the above three temperature sensors, so as to stably obtain hot water at the required temperature.

[0038] In some embodiments, such as Figure 1 , Figure 5 , Figure 6 shown, the water supply device provided by the present application is further provided with a purified water pump 400 for driving the water purified by the filter element 1100 to flow. The purified water pump 400 is connected to the heat exchange device 200 and communicates with the first channel 03. The purified water pump 400 is connected with a second speed regulation module 800 for adjusting the liquid flow rate. The second speed regulation module 800 is electrically connected to the first temperature sensor 101 and the second temperature sensor 102. It can be understood that the above purified water pump 400 is used to control the size of V2, and by adjusting the size of V2, the value of W can also be changed, so as to control the water temperature of the hot water output. Specifically:

[0039] Please refer to Figure 5 , Figure 6 for understanding. When the temperature of the energy medium inside the second channel 04 is higher than the required hot water temperature, the second speed regulation module 800 increases the flow rate of the water body in the first channel 03 through the purified water pump 400, so as to obtain hot water at the required temperature. On the contrary, when the temperature of the energy medium inside the second channel 04 is lower than the required hot water temperature, the second speed regulation module 800 reduces the flow rate of the water body in the first channel 03 through the purified water pump 400, so as to obtain hot water at the required temperature.

[0040] In some embodiments, such as Figure 6As shown, the water supply device provided by the present application is further provided with a control module 600, and the control module 600 is electrically connected to the first speed regulation module 700 and the second speed regulation module 800. The control module 600 can simultaneously perform cooperative control on the first speed regulation module 700 and the second speed regulation module 800, so that the water supply device can obtain hot water at a required temperature more flexibly.

[0041] In some embodiments, as Figure 5 shown, the water supply device provided by the present application is further provided with a faucet 500 for discharging hot water. The faucet 500 is connected to the heat exchange device 200, and the faucet 500 communicates with the water outlet end of the first channel 03; the control module 600 is also electrically connected to a temperature setting module 1000 for obtaining the required hot water temperature. The temperature setting module 1000 is disposed near the faucet 500 or connected to the faucet 500. In actual use, the user sets the required hot water temperature through the temperature setting module 1000, and the control module 600 controls the liquid flow rate ratio (i.e., the value of W) in the first channel 03 and the second channel 04 according to the temperature set by the user and the temperature detected by the temperature sensing component, so that the user can stably obtain hot water at the required temperature.

[0042] In some embodiments, the above-mentioned circulation pump 300 is also electrically connected to a timing module 900 for controlling the start and stop of the circulation pump 300 according to a set predetermined time interval. With such a setting, the circulation pump 300 can work intermittently, thereby ensuring that the temperature of the energy medium inside the second channel 04 is not too low, which helps to make the temperature of the discharged hot water more stable.

[0043] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 shown, the above-mentioned heat tank 100 is vertically arranged relative to the bottom of the water supply device. The heat tank 100 is provided with a medium inlet 01 and a medium outlet 02. The medium inlet 01 and the medium outlet 02 are respectively communicated with both ends of the second channel 04; the medium inlet 01 communicates with the top of the heat tank 100 or the side surface near the top, and the medium outlet 02 communicates with the bottom of the heat tank 100 or the side surface near the bottom. In the vertical state, the water temperature inside the heat tank 100 will be stratified up and down. The high-temperature water will be above the heat tank 100, and the low-temperature water will be below the heat tank 100. Therefore, through the above setting method, the heat exchange device 200 can obtain more high-temperature water.

[0044] In some embodiments, as Figure 3 shown, the heat tank 100 includes a tank body 11 for accommodating the energy medium and a heating device for heating the energy medium. The heating device is connected to the tank body 11, and the heating end of the heating device is disposed near the middle or bottom of the tank body 11.

[0045] Preferably, the heating end of the heating device is arranged in the middle of the tank body 11. The temperature of the energy medium in the middle of the tank body 11 is in an intermediate state, and thus it is easier to be heated to a high temperature. When the heating end of the heating device is heating, the heated water will rush upward into the top of the tank body 11. Therefore, only convection will occur between the middle and the top of the tank body 11, and the low-temperature water at the bottom of the tank body 11 will not be brought into the top of the tank body 11. This helps to maintain the temperature of the high-temperature water at the top of the tank body 11, so that the heat exchange device 200 can heat part of the energy medium to a relatively high temperature in a short time and accumulate it at the top of the tank body 11.

[0046] In other embodiments, the heating device can also be arranged outside the tank body 11. A pump body is used to drive the energy medium in the tank body 11 to circulate through the heating device. The heating device heats the flowing energy medium, and the heated energy medium flows into the tank body 11, realizing that the heating device heats the energy medium and stores it in the tank body 11.

[0047] In some embodiments, such as Figure 3 , Figure 4 shown, the above heat exchange device 200 includes an inner pipe 21 and an outer pipe 22. The inner pipe 21 is sleeved inside the outer pipe 22 to form a double-layer sleeve structure;

[0048] The lumen of the inner pipe 21 is the first channel 03. A gap is formed between the outer wall of the inner pipe 21 and the inner wall of the outer pipe 22, and the gap is the second channel 04. Or,

[0049] the lumen of the inner pipe 21 is the second channel 04, and the gap is the first channel 03;

[0050] The heat exchange device 200 is arranged along the inner side or the outer side of the hot tank 100.

[0051] Preferably, the lumen of the inner pipe 21 is the first channel 03 for circulating the water purified by the filter element 1100, and the gap is the second channel 04 for circulating the energy medium. With such a design, inside the heat exchange device 200, the water purified by the filter element 1100 will be in a state of being surrounded by the energy medium in terms of spatial distribution, and the heat is not easy to dissipate, and thus it is easier to be quickly heated to a relatively high temperature. The specific analysis is as Figure 6 shown ( Figure 6 the arrows in it are the heat transfer directions):

[0052] It can be understood that if the heat is transferred from the gap to the lumen of the inner pipe 21, the range of the water body that the heat needs to transfer shows a trend of gradually decreasing and gathering. If the heat is transferred from the lumen of the inner pipe 21 to the gap, the range of the water body that the heat needs to transfer shows a trend of gradually increasing and diffusing. By comparing the two, it can be understood that the former heat transfer method makes the heat easier to accumulate and the heat exchange efficiency is higher.

[0053] In some embodiments, a chamber 06 is provided inside the tank body 11, and the heat exchange device 200 is at least partially disposed in the chamber 06 and is used to contact with the energy medium. The heat exchange device 200 is disposed inside the chamber 06, and its exterior is in a high-temperature state. Thus, the heat inside it is not easily dissipated, and the heat exchange efficiency is higher. The tank body 11 also plays a certain heat preservation role for the heat exchange device 200.

[0054] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0055] It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0056] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
