Definitions

  • the invention is related to a device for supplying superheated water, comprising a container for containing water, and a heating element for heating water in the container to a superheated state.
  • the invention is further related to a domestic appliance comprising a device for supplying superheated water.
  • a device for supplying superheated water is known in practice.
  • a heating element provides heat to water present in a container, such that the water is superheated, typically 120 to 140 °C.
  • the container is closed; this means that the pressure in the container is suppressing the evaporation of the water.
  • a pressure cooker In practice such a device is also referred to as a pressure cooker.
  • the device for supplying superheated water comprises the heating element having a power P1 and the container for containing water. During operation the heating element heats the water in the container thereby generating superheated water and steam. Due to gravity water is present in what is usually called the lower part of the container and steam is present in the upper part of the container. In known devices an opening is present in the upper part for letting out steam. The opening is usually provided with an electro valve to control the amount of steam that is let out of the container. The amount of steam available in the container depends on the power P1. The higher the power P1, the more steam available in the container and therefore the higher the steam rate. In domestic appliances however, the power P1 is limited to the power available from a power/wall socket. As a result the amount of steam available in the container is limited to a certain maximum corresponding to P1.
  • a device for supplying superheated water comprising a water outlet for letting out superheated water.
  • the device according to the invention is defined in claim 1.
  • Superheating (sometimes referred to as boiling retardation, boiling delay, or defervescence) is the phenomenon in which a liquid is heated to a temperature higher than its standard boiling point, without actually boiling.
  • the term superheated water refers to liquid water under pressure between 100°C and its critical temperature, 374°C.
  • the pressure in the container is suppressing the evaporation of the water. If this superheated water is released from the container via the water outlet for letting out superheated water, it evaporates due to decrease of pressure when leaving the container. In practice the water outlet is at least partially below the water level during use. Experiments have shown that using the device according to claim 1 leads to a larger amount of steam than usually is obtained with steam generated in the container using power P1 and released from the container via the opening in the upper part of the container.
  • Steam in this paper may be dry steam or wet steam depending on the amount of water present.
  • the container is provided with a water zone and a steam zone, the water outlet being located at least partially in the water zone.
  • the water zone is the zone in the container where during use water is present
  • the steam zone is the zone in the container where during use steam is present.
  • the water outlet may be a water discharge opening in a wall of the container.
  • the water outlet is in contact with water present in the container.
  • the water outlet opening may be present at the -during use- bottom of the container. As water will flow to the lowest point this is an easy way to ensure that water in the container is present at the water outlet and, if at superheated temperature, available for generating steam.
  • the water outlet may be present as an opening in a side wall of the container, preferably near the bottom. During use the water outlet is -at least partly-below the water surface.
  • the device comprises a water transfer path, such as a hose, a pipe or a tube.
  • the water transfer path connects an opening in the wall of the container, a so-called wall opening- with water present in the water zone.
  • the water outlet is an opening in the pipe or tube, whereby the water outlet is located in the water zone. Practically it may be that one end of the tube is hanging in the water, while the other end is connected to the wall opening.
  • a set up may be practical in case, for instance for construction purposes, the wall opening is located close to the top or in the top of the container, while the water is at a level such that it is not in contact with the wall opening.
  • the water outlet is connected to an evaporation space for evaporating superheated water.
  • the evaporation space may for example be an evaporation chamber or a pipe.
  • the pipe may have an increased radius to facilitate evaporation of the superheated water.
  • the device comprises a water inlet for letting water into the container, the water inlet being located in the steam zone.
  • the steam is the zone is in the upper or higher part of the container during use. If the water inlet is located in the steam zone water upon entrance of the container water will fall under the force of gravity into the water zone. This way the amount of water in the container may easily be replenished.
  • the water outlet comprises a valve having an open and a closed position.
  • the valve In the open position superheated water will be let out for generating steam, after sufficient superheated water has been let out the valve will be closed.
  • the valve will be controlled by a controller for controlling the position of the valve in dependence of user input. For instance if the user presses a steam-shot trigger the valve is set to the open position generating a shot of steam. Alternatively the user may give a steam-flow trigger that results in a prolonged opening of the valve and thus of a prolonged expelling superheated water.
  • the container may have a steam outlet opening located in the steam zone.
  • a steam outlet may be used for letting out steam generated inside the container.
  • This is a usual configuration in known boilers or steam generators. This way a regular flow of steam is obtained.
  • the steam generated from evaporating superheated water may be used to give an additional shot of steam on top of the regular flow of steam.
  • the device further comprises a steam outlet located in the steam zone, the water outlet being in communication with a first transfer path and the steam outlet being in communication with a second transfer path.
  • the water outlet for generating steam form superheated water is connected to the first transfer path, such as a first hose or a first pipe.
  • An electro valve may be situated at the outside of the container at the location of the water outlet between the water outlet and the transfer path. Such electro valve is used for controlling the release of superheated water from the container.
  • the steam outlet is located in the steam zone of the container and is arranged for letting out the regular flow of steam which is present in the container.
  • a second electro valve may be provided at the steam outlet for controlling the release of steam from the container.
  • the steam outlet is connected to the second transfer path, such as a second hose or a second pipe.
  • each transfer path may be used to provide steam at a different region during use.
  • each transfer path may be used to provide steam at a different region in the sole plate.
  • This provides flexibility in the design. For instance steam generated from superheated water may, via the first transfer path, be transferred to a front zone located at the -so called- tip of the iron.
  • the steam obtained from the steam zone in the container may, via the second transfer path, be transferred to a back zone in the sole plate located closer to the -so called- heel of the iron.
  • first and second transfer path are joined to a mutual transfer path.
  • first and second transfer path are joined to a mutual steam transfer path.
  • the domestic appliance according to the invention comprises the device according to the invention.

  • a hose is provided between the electro valve and the steam chamber through which hose steam can be transported to the iron.
  • the electro valve In practice if the electro valve is triggered, it opens and the output of super heated water, which may also be referred to as yield of super heated water, travels from the container, also referred to as boiler, to the iron. Finally, steam leaves the iron through the sole plate openings in the sole plate of the iron.
  • the amount of steam available for ironing i.e. leaving the iron per unit time is called the steam rate.
