[0002] At present, water heaters are household appliances commonly used in people's daily lives. Water heaters are divided into electric water heaters, gas water heaters, heat pump water heaters and solar water heaters. Gas water heaters usually include a shell and components such as a burner and a heat exchanger arranged in the shell. The inlet and outlet pipes arranged on the shell are connected to the heat exchanger. After the cold water entering from the water inlet pipe is heated by the heat exchanger, hot water can be output from the water outlet pipe. However, the installation location of the water heaters in many users' homes is far away from the terminal bathing point. In winter, users need to release some cold water before hot water can be output, which causes users to wait too long.

[0057] A gas water heater is a water heater that uses gas as the main energy material and transfers the high-temperature heat generated by gas combustion to cold water flowing through a heat exchanger to prepare hot water.

[0058] A gas water heater generally comprises a shell, and components such as a burner, a heat exchanger, a fan and a fan cover arranged in the shell.

[0059] The gas is transported to the burner and ignited by an ignition device, so that the burner burns the transported gas to generate heat.

[0060] A heat exchange tube is arranged in the heat exchanger, one end of the heat exchange tube is connected to the water supply pipeline, and the other end of the heat exchange tube is connected to a shower head or a faucet.

[0061] The heat generated by the burner burning gas is used to heat the heat exchange tubes, so that the water temperature in the heat exchange tubes is increased to form hot water.

[0062] When the gas water heater is working, cold water provided by the water supply pipeline flows into the heat exchange tube, and then is heated into hot water by the heating source generated by the burner, and then flows out from the shower or faucet through the hot water valve for user use.

[0063] At the same time, when the gas water heater is working, the fan is powered on and runs at the same time. Under the action of the fan, the smoke generated by the burner is discharged to the outside.

[0066] The inner pot 2 is located in the water tank 1. The inner pot 2 is provided with a water inlet 21 and a water outlet 22. The inner pot 2 is a box with a certain capacity. The shape of the inner pot 2 can be set according to actual needs. The inner pot 2 is connected to the water inlet 21 with a water inlet pipe 7. The water inlet pipe 7 extends to the bottom of the inner pot 2 and is close to the heating element 23, and is used to transport cold water to the inner pot 2. The inner pot 2 is connected to the water outlet 22 with a drain pipe 8. The drain pipe 8 extends to the upper part of the inner pot 2 and is used to output the hot water in the inner pot 2. It can be understood that the end of the drain pipe 8 is higher than the end of the water inlet pipe 7.

[0067] In order to heat the water stored in the inner pot 2, a heating element 23 is provided on the inner pot 2. The heating element 23 is installed on the inner wall of the inner pot 2 and at a relatively lower position to effectively heat the water in the inner pot 2; specifically, the heating element 23 can be an electric heating tube or an electric heating wire, etc.

[0068] The hot water connector 11 is selectively connected to the water inlet 21 or the warm water connector 12 , and the warm water connector 12 is connected to the cold water connector 13 and the water outlet 22 .

[0069] Specifically, by setting a water tank 1, an inner tank 2 and a heating element 23, the water tank 1 is provided with a hot water joint 11, a warm water joint 12 and a cold water joint 13; the inner tank 2 is located in the water tank 1, and the inner tank 2 is provided with a water inlet 21 and a water outlet 22, the hot water joint 11 is selectively connected to the water inlet 21 or the warm water joint 12, and the warm water joint 12 is connected to the cold water joint 13 and the water outlet 22; when the user takes a shower in winter, the hot water joint 11 is connected to the water inlet 21, and the pipeline between the water outlet pipe of the gas water heater and the hot water joint 11 The cold water in the tank flows into the inner tank 2 through the hot water joint 11 and the water inlet 21, and the heating element 23 is energized to heat the water in the inner tank 2. The heated water is mixed with the cold water from the cold water joint 13 to obtain warm water with a constant temperature for users to use; when users take a shower in summer, the hot water joint 11 is connected with the warm water joint 12, and the hot water from the outlet pipe of the gas water heater is directly mixed with the cold water from the cold water joint 13 to obtain warm water with a constant temperature for users to use, thereby ensuring the constancy of the outlet water temperature and improving the user experience.

[0070] Specifically, the hot water connector 11 is selectively connected to the water inlet 21 and the warm water connector 12. When the hot water connector 11 is connected to the water inlet 21, the hot water from the gas water heater enters the inner tank 2 in the water tank 1 through the hot water connector 11 and the water inlet 21, and the heating element 23 in the inner tank 2 heats the water in the inner tank 2; when the hot water connector 11 is connected to the warm water connector 12, at this time, the hot water from the gas water heater passes through the hot water connector 11 and flows out from the warm water connector 12 without being heated by the inner tank 2; the warm water connector 12 is connected to the cold water connector 13 and the water outlet 22, so that the water in the inner tank 2 and the water in the cold water connector 13 can flow into the warm water connector 12.

[0071] In some embodiments of the present application, the hot water conversion device further includes a first reversing valve 3 .

[0072] The first reversing valve 3 is arranged in the water tank 1 and is located on the outside of the inner tank 2. The inlet of the first reversing valve 3 is connected to the hot water connector 11, an outlet of the first reversing valve 3 is connected to the water inlet 21, and the other outlet of the first reversing valve 3 is connected to the warm water connector 12.

[0073] Specifically, by setting the first reversing valve 3 in the water tank 1, the inlet of the first reversing valve 3 is connected to the hot water connector 11, one outlet of the first reversing valve 3 is connected to the water inlet 21, and the other outlet of the first reversing valve 3 is connected to the warm water connector 12, so that hot water enters from the inlet of the first reversing valve 3 and flows out from one outlet or the other outlet of the first reversing valve 3; it is convenient for the hot water connector 11 to be selectively connected to the water inlet 21 or the warm water connector 12 through the first reversing valve 3.

[0074] In some embodiments of the present application, the hot water conversion device further includes a first pipeline 4 and a temperature sensor 41 .

[0075] The first pipeline 4 is connected between the hot water connector 11 and the first reversing valve 3;

[0076] The temperature sensor 41 is disposed in the first pipeline 4 and is used to detect the water temperature in the first pipeline 4.

[0077] Specifically, by setting up a first pipeline 4 and a temperature sensor 41, the first pipeline 4 is connected between the hot water connector 11 and the first reversing valve 3, and the temperature sensor 41 is set on the first pipeline 4, which is convenient for detecting the temperature of water from the hot water connector 11 and providing a reference for subsequent control of the direction of hot water.

[0078] In some embodiments of the present application, the first reversing valve 3 includes a three-way valve.

[0079] Specifically, by setting a three-way valve, it is convenient to control the direction of water flow. When the water temperature is lower than the set value, the hot water enters the first reversing valve 3 through the hot water connector 11 and then enters the inner tank 2 through the water inlet 21 for heating; when the water temperature is higher than the set value, the hot water enters the first reversing valve 3 through the hot water connector 11 and does not enter the inner tank 2, but flows directly to the warm water connector 12.

[0080] In some embodiments of the present application, the hot water conversion device further includes a second reversing valve 5 .

[0081] The second reversing valve 5 is arranged in the water tank 1, located on the outside of the inner tank 2, the outlet of the second reversing valve 5 is connected to the warm water joint 12, an inlet of the second reversing valve 5 is connected to the cold water joint 13, and the other inlet of the second reversing valve 5 is respectively connected to the water outlet 22 and the other outlet of the first reversing valve 3.

[0082] Specifically, by arranging the second reversing valve 5 in the water tank 1, the outlet of the second reversing valve 5 is connected to the warm water joint 12, an inlet of the second reversing valve 5 is connected to the cold water joint 13, and the other inlet of the second reversing valve 5 is respectively connected to the water outlet 22 and the other outlet of the first reversing valve 3. In this way, cold water can flow into one end of the second reversing valve 5 and hot water can flow into the other end. After the cold water and hot water are mixed, the warm water flows out from the outlet of the second reversing valve 5, and finally the warm water flows out from the warm water joint 12, which is conducive to ensuring the stability of the outlet water temperature and avoiding the outlet water temperature being too high or too low.

[0090] In certain embodiments of the present application, the switch valve 61 includes a one-way valve.

[0091] Specifically, by setting a one-way valve, which is also called a non-return valve, the one-way valve can ensure that water flows from the water outlet 22 toward the second reversing valve 5, thereby preventing water from flowing in the reverse direction.

[0092] In some embodiments of the present application, a heat-insulating material is filled between the inner liner 2 and the water tank 1 .

[0093] Specifically, filling the insulation material between the inner liner 2 and the water tank 1 is beneficial to keeping the water in the inner liner 2 warm and reducing the heat loss of the water in the inner liner 2 .

[0094] Exemplarily, the thermal insulation material may be a polyurethane foam material. Of course, the thermal insulation material includes but is not limited to the above materials.

[0095] In a second aspect, an embodiment of the present disclosure provides a water heater, which includes a shell, a heat exchanger, and a hot water conversion device as described in any one of the embodiments of the first aspect.

Since the hot water conversion device includes any one of the first aspect embodiments, it has all the beneficial effects, which will not be described in detail.

[0101] In some embodiments of the present application, the working process of the hot water conversion device is as follows: when the user turns on the hot water in the shower, the hot water of the gas water heater flows out through the water outlet pipe. The cold water in the pipeline between the hot water outlet of the gas water heater and the hot water point flows into the hot water connector 11 of the hot water conversion device, and enters the first pipeline 4 after passing through the hot water connector 11. The temperature sensor 41 on the first pipeline 4 detects the inlet water temperature.

[0102] Combination Figure 2 As shown, when the inlet water temperature detected by the temperature sensor 41 is lower than the first set temperature (the first set temperature can be set by yourself), the inlet water flows through the first reversing valve 3 and then enters the inner tank 2 along the water inlet pipe 7. The heating element 23 heats the water in the inner tank 2 to a temperature higher than the second set temperature. The water higher than the second set temperature flows through the drain pipe 8 in the inner tank 2 through the switch valve 61 and the second reversing valve 5, and is mixed with the cold water from the cold water connector 13 at the second reversing valve 5 to obtain constant temperature hot water (the temperature of the constant temperature hot water can be adjusted according to the user's setting), and the constant temperature hot water flows out through the warm water connector 12 for user use.

[0103] Combination Figure 3 As shown, when the inlet water temperature detected by the temperature sensor 41 is not lower than the first set temperature, the inlet water flows through the first reversing valve 3 and then enters the second reversing valve 5 along the third pipeline 9, and mixes with the cold water from the cold water connector 13 at the second reversing valve 5 to obtain constant temperature hot water.

[0104] Exemplarily, the first set temperature is between 30° C. and 60° C.; the second set temperature is 50° C. When hot, the settings of the first set temperature and the second set temperature include but are not limited to the above situations.
