DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] Refer to the following Figure 1 Describe the technical solutions of some embodiments of the present invention.

[0030] like Figure 1As shown, an embodiment of the present invention provides an energy-saving warm water device for heating liquid in the energy-saving warm water device, the energy-saving warm water device comprising: a shell 110, wherein the shell 110 is provided with a shell inner cavity 111; a first partition 101 and a second partition 102, wherein the first partition 101 and the second partition 102 divide the shell inner cavity 111 into a first cavity 112, a second cavity 113 and a third cavity 114; a fourth cavity 115, wherein at least a portion of the fourth cavity 115 is provided in the first cavity 112, and another portion thereof is provided in the second cavity 113; a heating portion 201, wherein the heating portion 201 is provided in the fourth cavity 115; a pipe body 120, wherein the pipe body 1 At least a portion of the pipe 120 is provided in the second cavity 113, and one end of the pipe body 120 is connected to the water inlet pipe 170; the first flow guide pipe 130, the opening of one end of the first flow guide pipe 130 is provided in the first cavity 112, and the opening of the other end opposite to the first flow guide pipe 130 is provided in the second cavity 113, and the first flow guide pipe 130 is provided at the bottom end of the second cavity 113, which can ensure that the water at the bottom end of the second cavity 113 flows into the first flow guide pipe 130; the second flow guide pipe 140, the second flow guide pipe 140 is located in the first flow guide pipe 130, the height of its upper end is in the same plane as the height of the upper end of the pipe body 120, and the lower end of the second flow guide pipe 140 is connected to the second partition 102.

[0031] The energy-saving warm water device 100 of this embodiment is provided with a tube body 120 in the second cavity 113, so that the tap water with a temperature of k1 entering from the water inlet switch 180 exchanges heat with the liquid with a temperature of K3 in the second cavity 113 when passing through the second cavity 113 via the tube body 120, so that the temperature of the tap water reaches k2 when entering the fourth cavity 115 from the tube body 120. Therefore, in the fourth cavity 115, only the liquid with a temperature of k2 needs to be heated to a temperature of K3, without heating the liquid with a temperature of k1 to a temperature of K3, thereby realizing efficient utilization of energy and achieving energy-saving effect.

[0032] Specifically, in this embodiment of the present invention, a fourth cavity 115 is further provided within the inner cavity 111 of the housing. The fourth cavity 115 is a communicating vessel having two chambers, one of which is located within the second cavity 113 and the other within the first cavity 112. The openings of the two chambers are located at the same height. The left chamber is provided with a heating portion 201, and the diameter of the left chamber is slightly larger than that of the heating portion 201. The tube 120 is wound around the fourth cavity 115 from bottom to top and is connected to the chamber of the fourth cavity 115 located to the right of the second cavity 113.

[0033] Preferably, in an embodiment of the present invention, the second flow guide pipe 140 is located in the first flow guide pipe 130, the first flow guide pipe 130 passes through the first baffle 101, and its upper end opening is provided in the first cavity 112, and its height is higher than the highest water level line of the equipment, and its lower end opening is provided in the second cavity 113, and at the bottom end of the second cavity, there is a certain gap with the second baffle 102, so that it can ensure that the water at the bottom end of the second cavity flows into the first flow guide pipe 130, and the water entering the first flow guide pipe 130 is the low-temperature water in the lower layer of the second cavity 113; the height of the upper end of the second flow guide pipe 140 is the same plane as the height of the upper end of the pipe body 120, and the lower end thereof is provided in the second cavity 113. The end is connected to the second partition 102; because the height of the second flow conduit 140 is the same as the height of the tube body 120, the low-temperature water entering the first flow conduit 130 can overflow the opening of the second flow conduit 140 and enter the second flow conduit 140 to flow into the third cavity 114 only when the water in the second cavity 113 exceeds the height of the second flow conduit 140 and the tube body 120; the water flowing into the third cavity 114 is the warm boiled water after being boiled in the fourth cavity 115 and the temperature is lowered through heat exchange; the height of the second flow conduit 140 can adjust the heat exchange area of ​​the tube body 120, thereby changing the heat exchange power of the equipment, and then adjusting the water temperature of the output water of the equipment.

[0034] In the prior art, when providing 100°C boiling water, a drinking water supply device needs to heat low-temperature tap water, and the heated boiling water is converted into warm water through natural heat dissipation, resulting in a large amount of energy waste.

[0035] In summary, the energy-saving warm water equipment provided by the embodiment of the present invention effectively utilizes the heat dissipated when 100°C boiling water is cooled down through the setting of the pipe body 120, improves the energy utilization rate, and can stably provide boiling water and warm water after boiling.

[0036] like Figure 1 As shown, an embodiment of the present invention provides an energy-saving warm water boiling device. In addition to the above technical features, this embodiment further includes the following technical features.

[0037] The energy-saving warm water device of this embodiment includes: a first temperature detection device, which is provided in the first cavity and is used to detect the current liquid temperature T1 at the boiled water spout; a second temperature detection device, which is provided in the second cavity and is used to detect the current liquid temperature T3 at the first boiled water spout; a third temperature detection device, which is provided in the third cavity and is used to detect the current liquid temperature T5 of the second boiled water spout; a fourth temperature detection device, which is provided on the outside of the shell and is used to detect the external ambient temperature T7; the lifting height of the second guide pipe is H0; wherein H0=H1+H2(T7-T8) / T8, H1 is the first preset height, H2 is the second preset height, H1+H2 is the vertical distance from the water outlet of the second cavity 113 to the first partition 101, and T8 is the fourth preset temperature.

[0038] Preferably, in an embodiment of the present invention, four temperature detection devices are used to respectively detect the liquid temperature T1 in the first cavity 112, the liquid temperature T3 in the second cavity 113, the liquid temperature T5 in the third cavity 114, and the ambient temperature T7. T1 is compared with the first preset temperature T2, and T3 is compared with the second preset temperature T4. By raising and lowering the first flow conduit 130, T1 is controlled to be equal to the first preset temperature T2, and T3 is controlled to be greater than the second preset temperature T4. Furthermore, by detecting the ambient temperature T7, the second flow conduit 140 is controlled to be raised and lowered to adjust the heat exchange efficiency between the water in the second cavity 113 and the water in the tube body 120.

[0039] For example, in one embodiment of the present invention, when ambient temperature T7 is 30°C, the first preset temperature T2 is 100°C, and the second preset temperature T4 is 90°C, the height of the second flow guide tube 140 is adjusted to control the water level in the second chamber 113, thereby controlling the actual heat exchange area between the tube 120 and the water in the second chamber 114. The 30°C liquid in the tube 120 is heated to 90°C through heat exchange. In the fourth chamber 115, only the 90°C water needs to be heated to 100°C by the heating unit 201. In this case, the heat exchange power of the tube 120 is six times that of the heating unit. Because heat exchange in the tube 120 does not consume energy, 85% of energy can be saved.

[0040] For example, in another embodiment of the present invention, when ambient temperature T7 is 15°C, the first preset temperature T2 is 100°C, and the second preset temperature T4 is 75°C, the height of the second flow guide tube 140 is adjusted to control the water level in the second chamber 113, thereby controlling the actual heat exchange area between the tube 120 and the water in the second chamber 114. The 15°C liquid in the tube 120 is heated to 75°C through heat exchange. In the fourth chamber 115, only the 75°C water needs to be heated to 100°C by the heating unit 201. In this case, the heat exchange power of the tube 120 is 2.4 times that of the heating unit. Because heat exchange in the tube 120 does not consume energy, 70% of energy can be saved.

[0041] Specifically, in the embodiment provided by the present invention, a fourth temperature detection device 154 is further provided in the housing 110. The fourth temperature detection device 154 detects an external temperature T7, and combines this with a fourth preset temperature T8. After comparing T7 with T8, when T7 is greater than T8, the second flow conduit 140 adjusts its opening in the second cavity 113 upward, causing the liquid level in the second cavity 113 to rise, thereby increasing the contact area between the liquid in the second cavity 113 and the tube body 120 and improving the heat exchange efficiency. The second flow conduit 140 stops adjusting its temperature until the temperature of the liquid entering the second flow conduit 140 reaches the preset temperature T9.

[0042] For example, in another embodiment, the housing 110 is further provided with a fourth temperature detection device 154. The fourth temperature detection device 154 detects an external temperature T7, combines it with a fourth preset temperature T8, and compares T7 with T8. If T7 is less than T8, the second flow conduit 140 adjusts its opening in the second cavity 113 downward, lowering the liquid level in the second cavity 113. This reduces the contact area between the liquid in the second cavity 113 and the tube body 120, thereby lowering the heat exchange efficiency. The second flow conduit 140 stops adjusting its temperature until the temperature of the liquid entering the second flow conduit 140 reaches the preset temperature T9.

[0043] In this embodiment, by detecting the three cavities and the ambient temperature and by making the second flow guide tube 140 movable, the water storage capacity of the second cavity and the water temperature of the lowest layer in the second cavity and the water temperature in the third cavity can be adjusted. The simple structure is easy to manufacture, and the heat exchange power of the equipment can be adjusted by adjusting the height of the second flow guide tube 140 to achieve energy saving.

[0044] like Figure 1 As shown, an embodiment of the present invention provides an energy-saving warm water boiling device. In addition to the above technical features, this embodiment further includes the following technical features.

[0045] The energy-saving hot water device of this embodiment includes: a constant temperature tube 202, which is arranged in the third cavity 114; wherein, when T5 is greater than or equal to the third preset temperature T6, the constant temperature tube 202 is closed, and when T5<T6, the constant temperature tube 202 is opened.

[0046] Specifically, in an embodiment of the present invention, a thermostatic tube 202 and a third temperature detection device 153 are provided in the third cavity 114. The liquid temperature T5 in the third cavity 114 obtained by the third temperature detection device 153 is compared with a third preset temperature T6. When T5 is greater than or equal to T6, the thermostatic tube is closed.

[0047] For another example, in another embodiment, a thermostat tube 202 and a third temperature detection device 153 are provided in the third cavity 114. The temperature T5 of the liquid in the third cavity 114 obtained by the third temperature detection device 153 is compared with a third preset temperature T6. When T5 is less than T6, the thermostat tube is opened to maintain the temperature of the liquid in the third cavity 114 at T6.

[0048] In this embodiment, the temperature of the liquid in the third cavity 114 is controlled by the arrangement of the thermostatic tube 202 and the third temperature detection device 152, thereby achieving a stable supply of constant temperature water.

[0049] like Figure 1 As shown, an embodiment of the present invention provides an energy-saving warm water boiling device. In addition to the above technical features, this embodiment further includes the following technical features.

[0050] The energy-saving warm water device of this embodiment includes: a liquid level sensing electrode 161, which is arranged in the fourth cavity 115 and is electrically connected to the heating part 201; wherein, when the liquid level sensing electrode 161 is in contact with water, the liquid level sensing electrode 161 controls the heating part 201 to turn on; when the liquid level sensing electrode 161 is not in contact with water, the liquid level sensing electrode 161 controls the heating part 201 to turn off.

[0051] For example, in the embodiment provided by the present invention, the liquid level sensing electrode 161 is arranged in the chamber to the right of the fourth cavity 115, and the liquid level sensing electrode 161 penetrates at least 10MM into the opening of the fourth cavity 115. When the liquid level in the fourth cavity 115 reaches 10MM from the opening, the liquid level sensing electrode 161 contacts the liquid and sends a signal to control the heating part 201 to start heating. When the liquid in the fourth cavity 115 reaches a specified temperature and overflows, the liquid level sensing electrode 161 separates from the liquid and sends a signal to control the heating part 201 to stop heating.

[0052] In this embodiment, by providing the liquid level sensing electrode 161 , the device can control the function of the heating part 201 according to the liquid level in the fourth cavity 115 , thereby achieving a stable supply of boiling water by the device.

[0055] For example, in the embodiment provided by the present invention, the liquid level detection switch 162 is located in the chamber to the right of the fourth cavity 115 and can move up and down in the fourth cavity 115. At the same time, the liquid level detection switch 162 is communicated with the water inlet switch 180. Before the water level reaches the specified position, the liquid level detection switch 162 sends a signal to open the water inlet switch 180 to input tap water. When the water level reaches 10MM from the opening of the fourth cavity 115, the liquid level detection switch 162 sends a signal to close the water inlet switch 180 and stop the input of tap water.

[0056] In this embodiment, by setting the liquid level detection switch 162, the device can control the opening or closing of the water inlet switch 180 according to the change of the liquid level in the fourth cavity 115, thereby realizing the stable supply of boiling water and warm water by the device.

[0057] In another embodiment of the present invention, a full water sensing switch 163 is provided at the top of the first cavity 112. When the full water sensing switch 163 comes into contact with water, the water storage capacity inside the device reaches a maximum value. At this time, the water inlet switch 180 is closed, and water supply to the inside of the device stops. At the same time, the heating part 201 stops working.
