Description

An electric water heater capable of maintaining fresh water quality

technical field

The utility model belongs to the technical field of fluid heaters, in particular to an electric water heater capable of maintaining fresh water quality.

Background technique

An electric water heater is a fluid heating device that uses electricity as energy for heating. It is usually divided into two types: storage electric water heaters and instantaneous electric water heaters. Due to the relatively large power of instant electric water heaters and high wiring requirements, it is difficult to ensure sufficient hot water for bathing in winter. At present, storage electric water heaters are the most used.

The water storage type electric water heater usually includes components such as a shell, an inner tank, an electric heater, and a controller. The inner tank is used to pre-store a certain amount of hot water to ensure water consumption. However, during the use of storage-type electric water heaters, if the stored water is not used for a long time, or if the water consumption is small each time and the water storage replacement rate of the inner tank is low, the water stored in the inner tank will easily breed bacteria, and the smell will smell bad. bring inconvenience. With the improvement of people's living standards, users have higher and higher requirements for the water health of storage-type electric water heaters. During the use of storage-type electric water heaters, users hope to know the water quality of the inner tank of electric water heaters Hygienic conditions, and can replace the inner tank water or clean the sewage as needed. In addition, since there are more or less impurities in the tap water, if maintenance is not carried out for a long time, the service life of the electric water heater will be greatly affected.

In view of this, it is of great significance to design a way for the user to know the hygienic and clean condition of the water stored in the inner tank, and to allow the user to keep using healthy and clean hot water.

Utility model content

One purpose of the utility model is to provide an electric water heater that can maintain fresh water quality, reduce the growth of bacteria in the water stored in the inner tank, and improve the health of water.

Another object of the present utility model is to provide a fresh keeping method for inner tank water based on the above-mentioned electric water heater.

In order to achieve the above object, the utility model adopts the following technical solutions.

An electric water heater capable of maintaining fresh water quality, comprising: a housing, an inner tank arranged in the housing, a water inlet pipe, an outlet pipe, and a drain pipe connected to the inner tank, an electric heater installed in the inner tank, and A controller; it is characterized in that a first temperature sensor and a flow sensor are provided on the water inlet pipe, a second temperature sensor is provided in the inner tank, and a drain valve is connected to the drain pipe; the controller is connected with the electric heater, The first temperature sensor, the flow sensor, the second temperature sensor are connected to the drain ball valve for signals, the controller is connected with a display panel and an operation panel, and the operation panel is provided with fresh water setting buttons; the controller is provided with a power-off clock A running module circuit device, the power-off clock running module circuit device includes: a clock chip and an energy storage capacitor.

As a further illustration of the above solution, a display and control platform is provided at the bottom of the casing, and the display panel and the operation panel are arranged on the display and control platform.

As a further description of the above solution, the operation panel is a remote control device; or the operation panel is connected to the controller through wires.

As a further description of the above solution, the drain valve is an electric drain ball valve.

The utility model provides an electric water heater that can maintain fresh water quality, and its beneficial effects are: during actual work, the display panel displays the water inlet temperature, heating temperature and sewage discharge time interval in real time, and the user can set the heating temperature independently according to the needs, effectively avoiding overheating. The high heating temperature affects the replacement rate of the water stored in the inner tank to ensure fresh water quality in the inner tank. When the user uses the electric water heater for a period of time (the user can evaluate the local water quality and set the time), when impurities and dirt are deposited and affect the improvement of freshness, operate the fresh water setting button to open the electric drainage ball valve to realize the sewage discharge operation.

Detailed ways

In order to further facilitate those of ordinary skill in the art to better understand the essence of the utility model, the specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1-2, an electric water heater capable of maintaining fresh water quality includes: a housing 1, an inner tank 2 disposed in the housing 1, a water inlet pipe 3 and an outlet pipe 4 connected to the inner tank 2 , drainpipe 5, the electric heater 6 that is installed in liner 2 li, and controller. A first temperature sensor 7 and a flow sensor 8 are provided on the water inlet pipe 3, a second temperature sensor 9 is provided in the liner 2, and a drain valve 10 is connected to the drain pipe 5; the controller and the electric heater 6 , the first temperature sensor 7, the flow sensor 8, the second temperature sensor 9 are connected to the drain valve 10 for signals, the controller is connected with a display panel and an operation panel, and the operation panel is provided with fresh water setting buttons. The drain valve 10 is preferably an electric drain ball valve.

In this embodiment, the display panel and operation panel with freshness display function and fresh water setting function are arranged on the casing 1 of the electric water heater, more specifically, on the independent display and control platform at the lower part of the casing 1 13 on. The specific installation positions of the display panel and the operation panel should be convenient for users to view and trigger operations. For example, the operation panel is set as a remote control device; or the operation panel and the controller are connected by wires, and the operation panel is installed on the bathroom wall. Example.

The display panel and operation panel of the electric water heater include a display screen 11 for displaying freshness and fresh water setting buttons 12 . When powered on, the display screen 11 displays the stored water freshness value to the user in real time to prompt the user whether the water stored in the inner tank meets the health requirements for bathing. If it does not meet the health requirements for bathing, the user can replace the original water storage and drain the dirt in the inner tank to increase the freshness of the water storage.

As another embodiment, the display panel and the control panel are realized by a touch screen (not shown in the figure), so as to improve the appearance of the whole water heater. The user can realize the relevant function setting of fresh water by touching it.
