An electronic continuous-flow heater for heating a liquid includes an electrically heatable heating channel arrangement with at least one electric heating element, an electronic control system including at least one microprocessor configured to electrically control the heating element, and a display device connected by means of the electronic control system. The display device is designed as a bistable digital display such that the display content remains visible even in the absence of the display supply voltage of the display device.

A fluid-based heating apparatus that utilizes a centrifugal system with coupled friction heater to provide efficient heating by circulating fluids through the apparatus. The apparatus further including a central shaft connected to a motor drive that facilitates agitation of the fluid against frictional surfaces within the apparatus to generate heat.

Disclosed is a hot water generator comprising: a housing having a water inlet, a water outlet, and an inner space; and a heater disposed in the inner space of the housing, wherein the housing is provided with a helical flow formation unit which enables water flowing into the inner space to helically spin and flow along an outer surface of the heater.

The present application provides a heat exchange device and a dishwasher. The heat exchange device includes an evaporator, a first liquid storage tank, a second liquid storage tank and a power unit. A medium inlet and a medium outlet are defined in the evaporator, the first liquid storage tank is in communication with the medium inlet, and the second liquid storage tank is in communication with the medium outlet and the first liquid storage tank. A liquid inlet and a gas discharge port are defined in the second liquid storage tank. The power unit is arranged between the evaporator and the first liquid storage tank, or between the evaporator and the second liquid storage tank, so as to drive a liquid medium to circularly flow between the first liquid storage tank, the evaporator and the second liquid storage tank.

A water heater includes a tank and a heating pipe. The tank has a water storage space therein. A bottom of the tank is provided with a cold water inlet and a circulation outlet. The tank is provided with a hot water outlet located at a position not less than one half height of the tank. The heating pipe is connected with a circulation pipe outside the tank to communicate with the circulation outlet. The heating pipe extends upward from the bottom of the tank into the water storage space. The heating pipe is provided with an opening facing sideways. The opening is located at a certain height of the water storage space. An outside of the heating pipe is provided with a heating device for heating the heating pipe.

An electronic toilet and method of controlling the same. The electronic toilet includes a controller, a water spraying cleaner, a water chiller having a cold-water outlet pipe and a cold-water electromagnetic valve disposed on the cold-water outlet pipe, a water heater having a hot-water outlet pipe and a hot-water electromagnetic valve disposed on the hot-water outlet pipe, and a booster water pump. A water inlet of the booster water pump is connected to a confluent water outlet pipe of the water chiller through a water outlet pipe of the cold-water electromagnetic valve and the water heater through a water outlet pipe of the hot-water electromagnetic valve. A water outlet of the booster water pump is connected to the water spraying cleaner.

An electronic toilet and method of controlling the electronic toilet. The electronic toilet is connected to a cold water supply and a hot water supply and includes a controller that is configured to allow the electronic toilet to communicate cold water and/or hot water to a water straying cleaner that directed toward the anus of a user of the toilet.

A liquid heater such as a direct electrical resistance liquid heater having multiple flow channels is provided with a temperature-sensing element in the form of a wire extending across numerous channels, preferably all of the channels, near the downstream ends of the channels. The resistance of the wire represents the average temperature of the liquid passing through all of the channels, and hence the temperature of the mixed liquid exiting from the heater. A bubble suppressing structure is provided in the vicinity of the wire.
