In addition to issues such as heat insulation of the inner tank, the inability to quickly shut off the equipment after the water in the water heater has been heated to reduce equipment aging caused by continuous heating at high temperatures, the inability to maintain a stable water temperature after heating to reduce the need to frequently restart the heating plate to reheat due to water temperature drop, the inability to monitor the water temperature and water level in the inner tank in real time, the inability to quickly replace and repair the heating equipment after damage, and the inability of personnel to quickly clean the inner tank, this application provides a step-type electric water heater to meet these needs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a step-type electric water heater to solve the problems of equipment aging caused by continuous heating, maintaining a stable water temperature in the inner tank, real-time monitoring of water temperature and level, and facilitating maintenance of the heating equipment and cleaning of the inner tank.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A step-type electric water heater includes an outer shell, a cover on the upper surface of the outer shell, a base on the lower surface of the outer shell, an inner cover frame on the upper surface of the cover, a stainless steel cover inside the inner cover frame, an air cavity on the upper surface of the stainless steel cover, a mounting seat inside the base, a mounting plate on the upper surface of the mounting seat, a maintenance plate on the lower surface of the base, an inner tank inside the mounting plate, a heating plate on the lower surface of the inner tank, an electrode water level needle and a temperature probe arranged sequentially from front to back on the bottom surface of the inner tank, a controller and a faucet arranged sequentially from top to bottom on the surface of the inner tank, and a water inlet pipe at the bottom surface of the inner tank, one end of which is fitted with an electromagnetic water inlet valve.
[0007] Optionally, the surface of the inner liner is provided with a support frame, and the support frame has a support hole inside, the inner diameter of which is the same as the diameter of the inner liner.
[0008] Optionally, the bottom of the inner tank near the water inlet pipe is provided with a water level hole and a temperature hole. An electrode water level needle is inserted into the water level hole, and a temperature probe is inserted into the temperature hole.
[0009] Optionally, the surface of the heating plate is provided with a sudden temperature control, and the lower surface of the cover is provided with a connection hole, into which an inner liner is inserted.
[0010] Optionally, the outer shell has an internal insulation layer, and the upper surface of the cover has a water dispenser cover.
[0011] Optionally, the lower surface of the base is provided with a maintenance threaded hole, and maintenance threaded seats are provided on both sides of the maintenance plate. The maintenance plate is connected to the base by maintenance bolts.
[0012] Optionally, the mounting base has mounting holes inside, and the mounting plate has fixing holes at its four corners.
[0013] Optionally, the stainless steel cover has a cover sealing strip on its surface, and the air cavity has an air cavity sealing strip on its surface.
[0014] Optionally, the stainless steel cover has an air vent, and the air cavity has an exhaust vent.
[0015] Compared with the prior art, this utility model has at least the following beneficial effects:
[0016] In the above solution, a cover is used to fix the top of the inner tank. The stainless steel cover of the cover is placed on the inner tank. The heating plate boils the water in the inner tank. When the water boils, steam is generated and discharged through the vent hole of the stainless steel cover and the exhaust hole of the air chamber, and then through the boiling hole of the water heater cover. When cleaning the inner tank, the cover is pulled out to separate the connecting hole from the inner tank and quickly remove the cover. A support frame is installed on the surface of the inner tank to support the inner tank and the inner side of the outer shell, which facilitates daily cleaning of the inner tank and reduces scale inside the inner tank. The support frame installed on the surface of the inner tank also reduces the shaking of the inner tank during cleaning, thus reducing the impact on the cleaning speed.
[0017] By setting the temperature inside the inner tank to reach a specified value, the thermostat automatically shuts off the heating element to stop heating the inner tank. This quickly shuts down the device, reducing equipment aging caused by continuous heating and extending the water heater's lifespan. After the heating element stops heating the drinking water inside the inner tank, the insulation layer inside the outer shell keeps the water inside warm, reducing the need for frequent reheating due to temperature drops and lowering energy consumption.
[0018] The temperature inside the inner tank is monitored in real time by a temperature probe at the bottom of the inner tank, ensuring that the temperature remains within the set heating temperature range. An electrode water level needle inside the inner tank monitors the water level in real time; if the water level falls below the set safe level, the power is automatically cut off to prevent dry burning and avoid fires or other safety accidents caused by overheating. An electromagnetic water inlet valve is installed at the top between the inner tank and the outer shell, which facilitates water pressure control and prevents the air pressure inside the inner tank from exceeding the external air pressure. Water is added to the inner tank from top to bottom, effectively relieving water pressure and increasing water flow. A maintenance plate can be quickly installed and removed from the base using maintenance bolts. When the heating element fails to heat, it allows maintenance workers to quickly repair or replace it, reducing equipment downtime. Attached Figure Description

[0035] like Figures 2 to 7As shown, an embodiment of this utility model provides a step-type electric water heater device, including a housing 1. The upper surface of the housing 1 is provided with a cover 2. An insulation layer 101 is provided inside the housing 1. The upper surface of the cover 2 is provided with a water heater cover 201, with a water boiling hole inside the cover 201. The lower surface of the housing 1 is provided with a base 3. The upper surface of the cover 2 is provided with a cover inner frame 4. A stainless steel cover 5 is provided inside the cover inner frame 4. An air cavity 6 is provided on the upper surface of the stainless steel cover 5, with an air vent inside the stainless steel cover 5. An exhaust hole is provided inside the air cavity 6. A cover sealing strip 501 is provided on the surface of the stainless steel cover 5. An air cavity sealing strip 601 is provided on the surface of the air cavity 6. The base 3 is provided with a mounting seat 7. The upper surface of the mounting seat 7 is provided with a mounting plate 8. The mounting seat 7 has mounting holes inside. Fixing holes are provided at the four corners of the mounting plate 8. The lower surface of the base 3... The mounting plate 8 has a maintenance plate 9, and the lower surface of the base 3 has maintenance threaded holes. Maintenance threaded seats are provided on both sides of the maintenance plate 9. The base 3 is connected to the maintenance plate 9 by maintenance bolts 901. The mounting plate 8 has an inner liner 10 inside, and the surface of the inner liner 10 has a support frame 1001. The support frame 1001 has a support hole inside, and the inner diameter of the support hole is the same as the diameter of the inner liner 10. The lower surface of the inner liner 10 has a heating plate 11, and the surface of the heating plate 11 has a snap-action temperature controller 1101. The snap-action temperature controller 1101 is a snap-action temperature control switch. A snap-action temperature control switch is a temperature controller that uses a bimetallic strip as a temperature sensing component. When the appliance is working normally, the bimetallic strip is in a free state, and the contacts are in a closed or open state. When the temperature reaches the operating temperature, the bimetallic strip is heated and generates internal stress and moves rapidly, opening or closing the contacts, cutting off or connecting the circuit, thereby playing a role in temperature control. When the appliance cools down to the reset temperature, the contacts automatically close and open, restoring normal operation. A connection hole is provided on the lower surface of the cover 2, through which the inner liner 10 is inserted. The cover 2 and the inner liner 10 are not fixedly connected. From front to back, the bottom surface of the inner liner 10 has an electrode level needle 12 and a temperature probe 13. The electrode level needle 12 is a water level probe, an analytical instrument used for detecting water levels in boilers or water tanks. Commonly used water level probes include coffee machine water level probes, boiler water level probes, and water tank water level probes. The temperature probe 13 is an accessory used in thermometers. The thermocouple consists of two different wires, one end of which is... The thermocouple is welded together to form the measuring end, which is then inserted into the medium whose temperature is to be measured. The other end of the thermocouple is connected to a display instrument. If there is a temperature difference between the measuring end and the reference end of the thermocouple, the display instrument will indicate the thermoelectric potential generated by the thermocouple. The bottom of the inner tank 10 near the water inlet pipe 16 has a water level hole and a temperature hole. An electrode water level needle 12 is inserted into the water level hole, and a temperature probe 13 is inserted into the temperature hole. The surface of the inner tank 10 is provided with a controller 14 and a faucet 15 from top to bottom. The bottom of the surface of the inner tank 10 has a water inlet pipe 16, and one end of the water inlet pipe 16 is fitted with an electromagnetic water inlet valve 17.The cover 2 is attached to the top of the inner liner 10 through the connecting hole inside the cover body 2, thus fixing the cover body 2 to the top of the inner liner 10. The stainless steel cover 5 of the cover body 2 covers the inner liner 10. The heating plate 11 boils the water in the inner liner 10. When the water boils, steam is generated and discharged through the vent hole of the stainless steel cover 5 and the exhaust hole of the air chamber 6, and then through the boiling hole of the water heater cover 201. When it is necessary to clean the inner liner, the cover body 2 is pulled out to separate the connecting hole from the inner liner 10 and quickly remove the cover body 2. The inner liner 1001 is installed on the surface of the inner liner 10, so that the inner liner 10 inside the support frame 1001 is connected to the outer liner 10. The inner side of the shell 1 is supported to facilitate daily cleaning of the inner tank and reduce scale buildup inside. A support frame 1001 is installed on the surface of the inner tank 10 to reduce shaking during cleaning and slow down the process. When the internal temperature of the inner tank 10 reaches a specified value, a sudden-action temperature controller 1101 shuts off the heating element 11 to stop heating the inner tank 10, thus quickly shutting down the equipment and reducing aging caused by continuous heating, extending the lifespan of the water heater. The heating element 11 stops heating the drinking water inside the inner tank 10. Subsequently, the insulation layer 101 inside the outer shell 1 keeps the water in the inner tank 10 warm, reducing the need to frequently start the heating plate 11 to heat the water due to temperature drops, thus reducing energy consumption. The temperature inside the inner tank 10 is monitored in real time by a temperature probe 13 at the bottom of one side, ensuring that the temperature inside the inner tank 10 remains within the set heating temperature range. The water level in the inner tank 10 is monitored in real time by an electrode water level needle 12 inside the inner tank 10, and the power is automatically cut off when the water level is lower than the set safe water level. The source prevents dry burning, thus avoiding safety accidents such as fires caused by overheating. The electromagnetic water inlet valve 17 is installed at the top between the inner tank 10 and the outer shell 1, which is conducive to water pressure control and prevents the air pressure inside the inner tank 10 from being greater than the outside air pressure. Thus, when water is added to the inner tank 10 from top to bottom, the water pressure is effectively relieved and the water flow is increased. The maintenance plate 9 can be quickly installed and removed from the base 3 through the maintenance bolt 901. When the heating plate 11 cannot heat, it is convenient for maintenance workers to quickly repair or replace the heating plate 11, reducing the downtime of the equipment.
[0036] The working principle of this utility model is as follows: The electromagnetic water inlet valve 17 is installed at the top between the inner tank 10 and the outer shell 1, which facilitates water pressure control and prevents the air pressure inside the inner tank 10 from exceeding the external air pressure. Water is added to the inner tank 10 from top to bottom during water intake, effectively relieving water pressure and increasing water flow. The heating plate 11 boils the water inside the inner tank 10. The connecting hole in the cover 2 covers the top of the inner tank 10, fixing the cover 2 to the top of the inner tank. The stainless steel cover 5 of the cover 2 covers the inner tank 10. When the water boils, steam is generated and discharged through the vent hole of the stainless steel cover 5 and the exhaust hole of the air chamber 6, exiting through the water boiling hole of the water boiler cover 201. When the internal temperature of the inner tank 10 reaches the specified value, the heating plate 11 is shut off by the sudden temperature control 1101 to stop heating the inner tank 10. The temperature inside the inner tank 10 is monitored in real time by the temperature probe 13 at the bottom of one side of the inner tank 10. The water level inside the inner tank 10 is monitored in real time by the electrode water level needle 12 inside the inner tank 10. When the water level is lower than the set safe water level, the power is automatically cut off to prevent dry burning. After the heating plate 11 stops heating the drinking water in the inner tank 10, the water in the inner tank 10 is kept warm by the insulation layer 101 inside the outer shell 1. During cleaning, the cover 2 is pulled out to separate the connecting hole from the inner liner 10, allowing for quick removal of the cover 2. A support frame 1001 is installed on the surface of the inner liner 10, supporting the inner liner 10 against the inner side of the outer shell 1. This facilitates daily cleaning of the inner liner and reduces scale buildup. The maintenance plate 9 can be quickly installed and removed from the base 3 using the maintenance bolt 901. When the heating plate 11 fails to heat, it can be quickly repaired or replaced. This equipment facilitates daily cleaning of the inner liner, reducing scale buildup. The support frame 1001 installed on the surface of the inner liner 10... 1. It reduces the shaking of the inner tank 10 during cleaning, which affects the cleaning speed of personnel. It allows for quick shutdown of the equipment, reduces equipment aging caused by high temperatures due to continuous heating, and extends the service life of the water heater. It can maintain a stable water temperature, reducing the need to frequently start the heating plate 11 to heat the water when the temperature drops, thus reducing energy consumption. It can monitor the temperature inside the inner tank 10 in real time, ensuring that the temperature inside the inner tank 10 is kept within the set heating temperature range, and prevents dry burning, avoiding safety accidents such as fires caused by overheating. It also makes it convenient for maintenance workers to quickly repair or replace the heating plate 11, reducing the time the equipment is unusable.
