Description

Technical Field

[0002] At present, water heaters are commonly used household appliances in people's daily lives. Water heaters are divided into types such as electric water heaters, gas water heaters, heat pump water heaters, and solar water heaters. Electric water heaters are widely used because of their convenience. Among them, water heaters can be divided into storage water heaters and instant water heaters according to the heating power. The storage water heater has a large water output and stable water temperature because it is equipped with a water tank, and is purchased and used by more families. When the water heater is heating, the water pressure rises, causing the inner tank to expand, and even the problem of the inner tank bursting.

[0003] Usually, the above problems are solved by setting a safety valve on the water inlet pipe of the water heater. The safety valve has the function of a pressure relief valve. When the inner tank pressure rises above a certain value, the safety valve leaks water to discharge the excess pressure, thereby protecting the inner tank of the water heater. However, on the one hand, the water leakage from the safety valve will cause waste of water resources, and on the other hand, it will cause user complaints and other problems, resulting in poor user experience. In view of this, how to design a technology that can recycle the dripping water from the safety valve of the water heater to reduce water resource waste and improve the user experience is the technical problem to be solved by the utility model.

[0055] An electric water heater uses electric energy as the main energy material. After being powered on, the high-temperature heat generated directly heats the water stored in the electric water heater to achieve the purpose of preparing hot water.

[0056] An electric water heater generally includes components such as a water tank, an electric heating component, and an electric control board. Among them, a water storage cavity is formed in the water tank to store the water to be heated. The electric heating component is inserted into the water storage cavity formed by the water tank, and the electric control board is used to control the on-off operation of the electric heating component so that the water in the water tank is heated to a set temperature.

[0057] For the water tank of an electric water heater, the water tank generally includes a shell and an inner tank, and a heat insulation layer is formed between the shell and the inner tank. Among them, the shell is generally made of plastic material to meet the design requirements of diverse and beautiful shapes; the inner tank can be a metal inner tank or a plastic inner tank according to needs.

[0058] In addition, for the heat insulation layer formed between the shell and the inner tank, common heat insulation materials include: asbestos, sponge, foam plastic, polyurethane foam, etc. In conventional technology, in order to obtain a good heat insulation effect, the heat insulation layer is usually formed by foaming.

[0059] The water tank is also provided with a water inlet pipe and a water outlet pipe. The water inlet pipe is used to convey cold water into the water storage cavity formed in the water tank, and the hot water in the water storage cavity is output from the water outlet pipe.

[0060] For an electric heating component, electric heating methods such as electric heating wires, magnetic energy, or silicon tube heating can be adopted to heat the water stored in the water storage cavity.

[0061] For the electronic control board, it is used to receive the detection signals sent by relevant sensors (such as water temperature sensors, flow sensors), and at the same time, control the on-off operation of the electric heating component.

[0062] When the electric water heater is working, the electronic control board controls the electric heating component to be powered on for heating. When the water temperature in the water tank reaches the set value, the electronic control board controls the electric heating component to cut off the power.

[0063] Among them, for the inner tank, due to the influence of water quality, the inside of the inner tank is prone to corrosion. Therefore, a magnesium rod is also configured on the water tank, and the magnesium rod is inserted into the water storage cavity inside the water tank.

[0064] The magnesium rod is an important component in the electric water heater. It plays a role in protecting the inner tank, preventing the formation and accumulation of water scale, and extending the service life.

[0065] The magnesium rod is an alloy rod composed of metal elements such as magnesium, aluminum, chromium, zinc, and calcium. Since magnesium is the metal with the lowest potential in the electrochemical series and is non-toxic physiologically. In the electric water heater, the magnesium rod will react with calcium and magnesium ions in the water to form calcium carbonate and magnesium carbonate that are insoluble in water, thus avoiding the formation of water scale. Therefore, it is very ideal to use the magnesium rod to protect the inner tank.

[0066] In the first aspect, as shown in Figures 1 to 6 the present disclosure provides an inner tank assembly, which includes an inner tank 1, a water inlet pipeline 2, a safety valve 21, a water outlet pipeline 3, and a drip water recovery module 4.

[0070] The water outlet pipeline 3 is hermetically connected to the outlet;

[0071] As shown in Figure 1As shown, one end of the drip water recovery module 4 is communicated with the external leakage port of the safety valve 21, and the other end of the drip water recovery module 4 is communicated with the water outlet pipeline 3 and / or the water inlet pipeline 2. The drip water recovery module 4 is configured to recover the water discharged from the external leakage port of the safety valve 21.

In this way, when the pressure in the inner tank 1 increases, the pressure can be relieved by draining water through the external leakage of the safety valve 21, so as to realize the constant-pressure heating of the water in the inner tank 1, avoid the inner tank 1 from bursting, which is beneficial to protecting the inner tank 1 and prolonging the service life of the inner tank 1.

[0080] Specifically, by arranging the water pump 42 outside the water storage tank 41, connecting the water inlet of the water pump 42 to the water outlet end of the water storage tank 41, and communicating the water outlet of the water pump 42 with the water outlet pipe 3 and / or the water inlet pipe 2, the water pump 42 can pump out the water in the water storage tank 41 and send it into the water outlet pipe 3 or the water inlet pipe 2, realizing the recycling of water and avoiding the water level in the water storage tank 41 from being too high.

[0081] Combined with Figure 1 and Figure 2 As shown, in some embodiments of the present application, the drip water recovery module 4 further includes a second pipeline 43 and a first one-way valve 431.

[0082] One end of the second pipeline 43 is communicated with the water outlet of the water pump 42, and the other end of the second pipeline 43 is communicated with the water outlet pipe 3.

[0083] The first one-way valve 431 is arranged on the second pipeline 43, and the first one-way valve 431 is configured to prevent the water in the water outlet pipe 3 from flowing back into the water storage tank 41.

[0084] Specifically, by arranging the second pipeline 43 and the first one-way valve 431, one end of the second pipeline 43 is communicated with the water outlet of the water pump 42, and the other end of the second pipeline 43 is communicated with the water outlet pipe 3, so that the water pump 42 can pump the water in the water storage tank 41 into the second pipeline 43 and send it into the water outlet pipe 3 through the second pipeline 43, thereby realizing the anti-drip of the safety valve 21; the first one-way valve 431 is arranged on the second pipeline 43, and the first one-way valve 431 can prevent the water in the water outlet pipe 3 from flowing back into the water storage tank 41, which is beneficial to protecting the stable operation of the water outlet pipe 3.

[0085] Combined with Figure 3 and Figure 4 As shown, in some embodiments of the present application, the drip water recovery module 4 further includes a third pipeline 44 and a second one-way valve 441.

[0086] One end of the third pipeline 44 is communicated with the water outlet of the water pump 42, and the other end is communicated with the water inlet pipe 2.

[0087] Specifically, the other end of the third pipeline 44 is communicated with the water inlet end of the water inlet pipe 2.

[0088] The second one-way valve 441 is disposed on the third pipeline 44, and the second one-way valve 441 is configured to prevent the water in the water inlet pipeline 2 from flowing back into the water storage tank 41.

[0089] Specifically, by providing the third pipeline 44 and the second one-way valve 441, one end of the third pipeline 44 is communicated with the water outlet of the water pump 42, and the other end of the third pipeline 44 is communicated with the water inlet pipeline 2.

[0090] It should be noted that in the drip water recovery module 4, the second pipeline 43 and the third pipeline 44 can exist separately or simultaneously.

[0091] Combined Figure 1 and Figure 2 as shown, the second pipeline 43 exists alone, wherein, Figure 1 the arrow in indicates the water flow direction of the inner tank assembly in the normal state, Figure 2 the arrow in indicates the water flow direction of the safety valve 21 in the pressure relief and drainage state.

[0107] Specifically, when the water level does not reach the set water level line, the control module controls the water pump 42 to stop working; when the water level reaches the set water level line, the liquid level sensor 411 transmits the water level signal detected in the water storage tank 41 to the control module. The control module receives the water level signal and controls the water pump 42 to start. The water pump 42 pumps the water in the water storage tank 41 into the third pipeline 44. Due to the control of the flow direction of the water flow by the second one-way valve 441, the water flows through the third pipeline 44 and into the water inlet pipeline 2, realizing the recycling of water. When the water in the water storage tank 41 is pumped out, the control module controls the water pump 42 to stop working.

[0108] In the third case, when the second pipeline 43 and the third pipeline 44 exist simultaneously, both the water pump 42 and the liquid level sensor 411 are electrically connected to the control module. The liquid level sensor 411 transmits the water level signal detected in the water storage tank 41 to the control module. The control module receives the water level signal and controls the start and stop of the water pump 42 according to the water level signal.

[0109] Specifically, when the water level does not reach the set water level line, the control module controls the water pump 42 to stop working; when the water level reaches the set water level line, the liquid level sensor 411 transmits the water level signal detected in the water storage tank 41 to the control module. The control module receives the water level signal and controls the water pump 42 to start. The water pump 42 pumps the water in the water storage tank 41 into the second pipeline 43 and the third pipeline 44 respectively.
