Description

Technical Field

[0001] The utility model relates to the technical field of electric water boilers, in particular to a double disinfection and sterilization electric water boiler. Background Art

[0002] A water boiler, also called a water heater, an electric water heater, or commonly known as a "water boiler", is a water-boiling device that converts electrical energy into thermal energy and is designed to meet the drinking water needs of different groups of people. The existing water boiler heats cold water through a built-in heating tank and then delivers it to the faucet. After the switch is pressed manually, hot water is delivered.

[0003] The problem with the existing water boiling machine principle is that it only relies on UV ultraviolet disinfection. However, each time the switch is pressed to deliver hot water, the natural pressure of the tap water pushes the hot water in the heating water tank to the faucet for delivery. During this pushing process, the hot water will be transported through the pipe, and the hot water that is not completely released will remain in the pipe and cannot be discharged further. The hot water stored in the pipe gradually cools down and comes into contact with the air, so the problem of bacterial contamination cannot be solved at all. In the prior art products, when drinking is turned on, the boiling water in the heating water tank flows through the delivery pipe and flows out of the faucet. When the water is stopped, the stored water in the pipe cannot be completely emptied, and the cooled stored water retained in the pipe comes into contact with the air. Bacteria, viruses and other harmful microorganisms will grow in the drinking water that is taken again, and high-temperature disinfection cannot be achieved. In addition, after the boiling water in the heating water tank flows out, cold water is quickly replenished, and the temperature drops sharply after the hot water and cold water are mixed. It needs to be heated to boiling again. This process requires waiting for a certain period of time and cannot be used immediately. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an electric water boiler with high temperature disinfection and double disinfection and sterilization on the basis of UV ultraviolet disinfection and sterilization, so as to solve the problems raised in the above background technology. The utility model has a novel structure:

[0005] When making water normally: first, it is heated by a small water tank with a fixed capacity of 13L. After boiling, according to the physical phenomenon of water expansion and contraction, the water level rises sharply, and under the action of boiling (commonly known as bubbling), the high-temperature pure boiled water overflows to the disinfection water tank for high-temperature disinfection. There are two sets of heat exchangers in the disinfection water tank. The boiled water and the normal temperature water in the heat exchanger are independently sealed. The heat of the boiled water is released in large quantities, and it is converted into warm boiled water and then enters the storage water tank. It is disinfected and sterilized by UV ultraviolet rays when drinking. At the same time, after the normal temperature water absorbs a large amount of boiled water heat, the water temperature rises to 86℃ (real test data). After absorbing the heat, the water enters the heating water tank for heating and is quickly boiled, which greatly saves electricity and shortens the boiling time.

[0006] When the high-temperature disinfection mode is started: the solenoid valve at the bottom of the pipeline opens, allowing the retained water in the output pipeline connected to the faucet to dangle naturally by gravity for drainage, and then under the action of the micro pump, the high-temperature boiling water in the heat exchanger is pressure-transported into the pipeline to stay (the time can be set to 10-30 seconds), thereby achieving the purpose of high-temperature disinfection. The startup process can be set to automatically repeat the above disinfection steps. During each rotation, the water retained in the pipeline can be returned to the heating box through the reflux pipe, or directly discharged. The dual disinfection and sterilization method of high temperature and UV ultraviolet rays is truly used to avoid bacteria contamination in the water source and ensure water quality safety.

[0007] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an electric water boiler with double disinfection and sterilization, comprising a water boiler body, a control panel is installed on the top of the front end of the water boiler body, and four groups of switches are arranged at the bottom of the control panel at the front end of the water boiler body, a water faucet is installed at the bottom of the switch, two groups of heating boxes are installed at the bottom of the back of the water boiler body, and two groups of disinfection boxes are installed at the top of the heating box on the back of the water boiler body, the heating box and the disinfection box are connected through a water pump and a pipeline, a delivery pipe is arranged at the outlet end of the disinfection box, a connecting pipe connected to the water faucet is installed at the top of the back of the water boiler body, an adjustment component is arranged between the inlet end of the connecting pipe and the delivery pipes on both sides, the adjustment component comprises a water delivery tray, the water delivery tray is fixed on the back of the water boiler body, and a circular plate is rotatably installed inside the water delivery tray through a bearing, and a through hole is opened on the surface of the circular plate.

[0008] Furthermore, a return pipe is provided on one side of the bottom of the water delivery tray, and the bottom of the return pipe is connected to the top of the side edges of the two groups of heating boxes.

[0009] Furthermore, the size of the through hole is the same as the caliber of the return pipe and the delivery pipe, and a shaft is rotatably mounted on the bottom of the water delivery tray through a bearing, and the shaft is fixedly connected to the circular plate.

[0010] Furthermore, a mounting seat is fixed on the inner wall of the water boiler at the bottom of the water delivery tray, and a motor is fixedly installed inside the mounting seat, and the output end of the motor is fixedly connected to the shaft rod.

[0011] Furthermore, a valve is installed inside the delivery pipe parallel to the shaft rod, and the valve stem of the delivery pipe rotates to pass through the delivery pipe.

[0012] Furthermore, a gear is fixed to the protruding end of the valve stem, and a toothed plate is meshedly connected to the bottom of the gear, and a convex plate is fixed on the surface of the toothed plate close to the shaft.

[0013] Furthermore, the adjustment assembly also includes a fixing ring, the fixing ring is sleeved on the surface of the shaft, a push plate is fixed to one side of the fixing ring, and the push plate can be in compression contact with the convex plate.

There is an adjustment component 5, which includes a water supply tray 51. The water supply tray 51 is fixed on the back of the water boiler body 1, and a circular plate 57 is rotatably installed inside the water supply tray 51 through a bearing. A through hole 58 is opened on the surface of the circular plate 57. In this application, the control panel 11 adopts the technology of BAS system control to display the temperature and control the opening status, and the interior of the disinfection box 3 is UV ultraviolet disinfection of the prior art. When the device is used, the two groups of hot water tanks and the disinfection box 3 are heated and disinfected at the same time. Then the adjustment component 5 alternately opens the delivery pipe 31, and the hot water is delivered to the four water outlet faucets 13 through the connecting pipe 4. The hot water is delivered and the hot water retained in the pipeline is returned to the heating box 2 through the reflux pipe 21 for re-disinfection and heating treatment.

[0027] In this embodiment, a return pipe 21 is provided on one side of the bottom of the water delivery tray 51, and the bottom of the return pipe 21 is connected to the top of the side of the two sets of heating boxes 2.
