Technical Field
The invention relates to the technical field of household appliances, in particular to a water heater.
Background
The water heater is a device which can raise the temperature of cold water into hot water in a certain time by various physical principles. Common water heaters store water in the inner container, and in order to reduce corrosion of acidic components in the water to the inner container, a magnesium rod is added into the inner container for cathode protection. Magnesium carbonate generated by the reaction of the magnesium rod and various impurities such as calcium carbonate, ferric oxide and the like doped in water need to be discharged out of the inner container in time, otherwise thick water scales formed by long-time accumulation are difficult to discharge. The scale covering the heating device isolates the heating device from the water, thereby hindering effective heat transfer and affecting heating performance. Meanwhile, the accumulation of the scale can cause the growth of bacteria.
The existing method for discharging the dirt comprises the steps that a drain outlet is formed in the inner container, meanwhile, the drain outlet is controlled to be opened and closed through the drain valve, after the drain valve is opened, partial water scales can be discharged along with water flow, in addition, the water inlet pipe is close to the bottom of the inner container, and the water flow entering the inner container can wash away the partial water scales at the bottom of the inner container. However, in order to ensure a high hot water output rate during normal use, the inflow of water into the water inlet pipe is required to be as gentle as possible, which is contradictory to the desire for a large water flow during sewage discharge, and therefore, the effect of cleaning the inner container by the inflow of water from the water inlet pipe is limited. Meanwhile, in order to ensure the normal use of the water heater and prevent the waste of water resources, the sewage draining port cannot be opened frequently to drain sewage, and water and dirt in the water heater cannot be emptied completely, so that water scales are accumulated on the bottom surface of the liner under the action of gravity. Therefore, the water heater still needs to regularly remove the scale by professional staff, which is time-consuming and labor-consuming and increases the cost.

Wherein, 1, the inner container; 2. a water outlet pipe; 3. a water inlet pipe; 4. a sewage draining outlet; 5. a bypass pipe; 6. a housing; 7. a blowoff valve; 8. a water regulating valve; 9. an electric heating device.
Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
As shown in fig. 1, the embodiment protects a water heater, which comprises an inner container 1 and a water outlet pipe 2 communicated with the inner container 1, wherein a sewage outlet 4 is further arranged at the bottom of the inner container 1, and a bypass pipe 5 is connected with the sewage outlet 4 and the part of the water outlet pipe 2 positioned outside the inner container 1.
The drain 4 of the 1 bottom of inner bag of this water heater passes through bypass pipe 5 and is connected with outlet pipe 2, because the rivers flow fast in the outlet pipe 2, make the water velocity of inner bag 1 bottom increase, be favorable to arranging the incrustation scale by drain 4 to outlet pipe 2 in, flow by outlet pipe 2, in addition, because the hot water frequency of using in the family is higher, the water heater is higher by the frequency of outlet pipe 2 drainage water, the incrustation scale flows thereupon, so the incrustation scale is difficult for forming cubic sediment, can not deposit in 1 bottom of inner bag, needn't let the professional scale removal again, practice thrift the cost, the use of water heater is also more convenient.
The outlet pipe 2 of this embodiment is even gone out by the bottom of inner bag 1, the part that outlet pipe 2 is located inner bag 1 inside extends to the top of inner bag 1, the water that gets into outlet pipe 2 by the top is the hot water after the heating, the inlet tube 3 of water heater and the bottom intercommunication of inner bag 1, intake by inner bag 1 bottom, the rivers of inlet tube 3 are favorable to the discharge of incrustation scale, the water that gets into outlet pipe 2 by bypass pipe 5 is the water that has just flowed in by inlet tube 3, the temperature is lower, the temperature at inner bag 1 top has not been reached yet, the temperature of discharge water can be adjusted to the water combination of bypass pipe 5 and outlet pipe 2.
The water heater in the embodiment further comprises a shell 6, the bypass pipe 5 is located outside the shell 6, the bypass pipe 5 is detachably connected with the water outlet pipe 2, and after the bypass pipe 5 is blocked, the bypass pipe 5 is conveniently detached for dredging, so that the water heater is convenient to maintain.
As shown in figure 2, the bypass pipe 5 is provided with a blowoff valve 7, which can control the on-off of the bypass pipe 5 and control whether to blow off the sewage at any time, and in addition, when the bypass pipe 5 needs to be dredged, the blowoff valve 7 is closed, and the maintenance work of the bypass pipe 5 can be carried out without emptying the water in the inner container 1.
Preferably, the bypass pipe 5 is a memory metal alloy, and when the temperature of water in the bypass pipe 5 is high, the pipe diameter of the bypass pipe 5 becomes large, and when the temperature of water in the bypass pipe 5 is low, the pipe diameter of the bypass pipe 5 becomes small. On the one hand, because when the temperature of water is higher, the water in the inner bag 1 is easy to scale, and at the moment, the pipe diameter of the bypass pipe 5 is increased, so that more water with scale can be discharged, and the scale deposit when the temperature of water is higher can be prevented. On the other hand, when the water temperature of the bypass pipe 5 is higher, the water temperature at the top of the inner container 1 is higher, at the moment, the pipe diameter of the bypass pipe 5 is increased, the temperature of the water in the water outlet pipe 2 after the confluence is facilitated to be balanced, and the water temperature of the water flowing out of the water outlet pipe 2 is proper. Similarly, when the water temperature in the bypass pipe 5 is low, the water temperature can be balanced by reducing the pipe diameter of the bypass pipe 5, so that the water temperature of the water flowing out of the water outlet pipe 2 is moderate. Specifically, the memory metal alloy is a titanium-nickel alloy.
A water regulating valve 8 is connected between the water inlet pipe 3 and the water outlet pipe 2, so that the water temperature of the outlet water can be further regulated and controlled, and the water temperature can meet the requirements of different individuals.
The water heater of the embodiment further comprises an electric heating device 9, and the water temperature in the inner container 1 is increased through electric heating. Of course, the water heater can also be a water heater heated by solar energy or gas.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
