Problems solved by technology

[0003] However, this type of protective device can only be used as a first aid remedy in the event of an electric leakage, and cannot achieve a preventive effect.
Even if the electric water heater equipped with the above protection devices has a leakage behavior, the user will still be injured for a short time

Embodiment 1

[0016] refer to figure 1 As shown, as a water storage type electric water heater according to an embodiment of the present invention, a water pressure sensing device 10 for detecting water pressure is installed on the outlet pipe of the water storage type electric water heater, and the water pressure sensing device 10 is connected to a The sending control device 20 is connected in series with a switching device 30 on the power supply circuit of the water storage electric water heater, and the switching device 30 is connected with a receiving control device 40 . The other parts of the storage type electric water heater of this embodiment are the same as the conventional storage type electric water heater of the prior art, and also include a water heater host, a cold water pipeline, a hot water pipeline, and a cold water pipeline connected with a hot water pipeline. Mixing valve, faucet, pressure relief valve, etc. will not be described in detail here. Wherein, the water pressu...

Embodiment 2

[0023] refer to figure 2 As shown, the water storage type electric water heater of this embodiment is basically the same as that of Embodiment 1, the difference is that: the sending control device 20 and the receiving control device 40 of this embodiment are connected by wireless transmission, so as to avoid Wiring is cumbersome. Preferably, a Bluetooth module is used for wireless communication connection.

Abstract

The invention relates to electric water heaters, in particular to a water storage type electric water heater. A water outlet pipeline of the water storage type electric water heater is provided with a water pressure sensing device used for detecting water pressure; the water pressure sensing device is connected with a sending control device; an on-off switching device is connected to a power supply loop of the water storage type electric water heater in series; the on-off switching device is connected with a receiving control device; the water pressure sensing device transmits a detected water pressure signal to the sending control device; the sending control device obtains the on-off condition of a water path of the water heater according to the water pressure signal and transmits the water path on-off judgment signal to the receiving control device; the receiving control device controls the on-off switching device to conduct connection and disconnection operations on the power supply loop of the water storage type electric water heater according to the received water path on-off judgment signal. A power source of the water heater can be completely turned off before a user touches water, so that absolute security is ensured.

Description

technical field [0001] The invention relates to an electric water heater, in particular to a storage type electric water heater. Background technique [0002] Water storage type electric water heater refers to a fixed appliance that heats water, has a container for storing hot water, it can store hot water for a long time or temporarily, and is equipped with a device to control or limit the water temperature. There are tens of thousands of electric water heater leakage accidents in the world every year, so the use of electric water heaters requires certain electrical safety protection measures. The safety measures of the existing storage-type electric water heaters mainly rely on leakage protection circuits, such as leakage protection sockets, leakage protection devices, and electric partition walls. The safety protection of existing electric water heaters also mainly proposes improvement in this respect, as patent documents such as CN1433116, CN101860006A, CN101275779. ...
