Description

Field of the invention

The invention relates to a device for heating a liquid with a vessel for receiving the liquid and a holder, and a holder in which a vessel is used.

Background of the invention

In conventional kettles, the water to be heated is usually filled in a water tank in which a heating coil is located. By activating the kettle, the heating coil is heated, which in turn delivers the heat to the surrounding water. Modern devices have instead of the heating coil heating elements, which are mounted under a bottom plate of the water tank. These heating elements heat the bottom plate, which in turn heats the water above it. Power is supplied either by a power cord connected directly to the kettle or via an independent base. The base is connected to the power supply and transmits power by means of a power supply coupling to the kettle. A power supply via a power supply coupling allows the kettle to move freely, reducing the risk of injury from boiling water. In all these water heaters, however, the unit with the water tank always includes the electronic components for heating the water. As a result, it is hardly possible to reliably clean the water tank. Heating spirals and heating floors should not be exposed to harsh cleaning agents if possible. In addition, an automatic cleaning, for example, in a dishwasher, not possible because it could get into the interior of the device and damage the electronics.

A thorough and reliable cleaning of hot water appliances, especially if they are not constantly in use, but is required, since the lime deposits formed during boiling water form a preferred breeding ground for microorganisms. Regular cleaning would not only kill microorganisms, but also reduce calcification from the outset.

The invention is therefore based on the object to provide a device for heating liquids, in which the vessel for receiving the liquid can be easily cleaned and optionally disinfected.

Detailed description of the invention

The invention relates to a device for heating a liquid with a vessel for receiving the liquid and a holder. The vessel has a bottom and a vessel rim opposite the bottom, which edges around an opening through which the vessel is open at the top. Through this opening liquid can be filled into the vessel and poured out of the vessel.

The holder has a base, a pillar and a lid. The base has on its top a receiving platform on which the vessel is placed with its bottom. Furthermore, the base has a heater, which is arranged below the receiving platform and transfers heat to the vessel. In this way, the liquid in the vessel is heated. The column is attached to the pedestal and extends upwardly therefrom. At the top, the base facing away from the end of the column, the lid is attached.

The lid has a locking unit, which can be brought into two different configurations, namely in a closed position and an open position. In the closed position of the locking unit, the lid engages in the opening in such a way that the lid and the pillar surround the edge of the vessel from above. In addition, the lid is fixed in the closed position of the locking unit at the end of the column in the vertical direction. As a result, in the closed position of the locking unit, the vessel is firmly gripped by the base on the base, the pillar and the lid at the edge of the vessel. It is anchored in the holder and can neither fall out nor be removed. In the open position of the locking unit, the lid is out of engagement with the edge of the container, so that the container is released from the holder and can be removed.

The locking unit can be brought by pressing the lid from the closed position to the open position. The lid thus fulfills two functions, it serves both for closing the opening of the vessel as well as for anchoring and releasing the vessel in or out of the holder. In this case, the lid for filling and emptying of the vessel can be opened without bringing the locking unit in the open position.

The heater and any other electronic components that may be present are part of the fixture and can be completely separated from the vessel in which the liquid is heated. This allows the vessel to be thoroughly cleaned, if necessary even chemically cleaned, or washed in a dishwasher. If necessary, the vessel can also be disinfected by machine.

In addition, the vessel can also be replaced or replaced. If the vessel is damaged, it is not necessary to replace the entire device, that is also the electronic components. This can reduce the consumption of expensive materials, especially precious metals and rare earths. Furthermore, the invention allows a simple production of series of differently shaped devices, wherein the holder is always the same, the vessel, however, can be designed individually.

In a preferred embodiment, the lid is pivotable. Hiebei is both a vertical and a horizontal pivoting of the lid possible, but a vertical pivoting allows easier handling of the device. A hinged lid facilitates both the opening and closing of the vessel as well as the release of the lock of the vessel.

In a preferred embodiment, the locking unit is a swivel mount. With this, the lid engages in the opening of the vessel. The swivel mount is preferably arranged at a position at which the lid is attached to the column, so that the swivel mount engages in the opening, and the edge of the vessel is encompassed by the lid and pillar. By pivoting the lid, on the one hand, the vessel can be opened for filling or emptying. On the other hand, the lid can be actuated by pivoting and thereby bring the locking unit in an open position.

In a preferred embodiment, the locking unit can be brought from the open position into the closed position by opening the lid from the closed position into the open position and by closing the lid from the open position. When closed, the lid closes the opening of the vessel. This allows for efficient heating of the liquid in the vessel. For filling and emptying the vessel, the lid can be opened. By opening the lid but also the locking unit of the Closed position are transferred to the open position. This can be made possible, for example, by releasing a fuse on the locking unit. Alternatively, the lid may be formed so that the locking unit is brought into the open position as soon as the lid reaches a certain position, the unlocking position. For all other positions of the lid, however, the locking unit is in the closed position. When the lid is opened up to the unlocking position, the lid thus passes through various positions in which the vessel is accessible.

In a preferred embodiment, the lid is open in the open position of the locking unit, to over 90 °, preferably to over 100 °, further preferably to over 120 °. The locking unit is transferred by opening the lid from the closed position to the open position, wherein the open position is reached when the lid reaches the unlocking position. In the intermediate positions, the vessel is accessible without loosening the locking unit. The unlocking position is reached as soon as the lid is opened to over 90 °, preferably to over 100 °, further preferably to over 120 °. To fill and empty the vessel, the lid must be opened to a maximum of 90 °. Only when it is opened beyond, the lock is released, so that the vessel can be removed from the holder. This allows safe operation of the device, especially if it is filled with hot water.

In a preferred embodiment, the locking unit comprises a latch and a locking hook, wherein the latch is pivotally attached to the column, and rests with an upper end on the edge of the vessel and the locking hook engages around the upper end of the latch and the edge of the vessel. This allows a firm but easy-to-handle locking of the vessel in the holder. The lid can be opened up to about 90 ° without loosening the lock of the vessel. On the other hand, if the lid is opened further, the closing hook is loosened and the lid presses against the bar, so that this too is released from the edge of the container. For this purpose, in contrast to the simple opening of the lid more force is required, whereby accidental opening of the lock is prevented.

In a preferred embodiment, the receiving platform has a recess for receiving the vessel. By placing the vessel with its bottom in a recess increases the stability of the vessel in the holder. In addition, the locking of the vessel and holder is more stable and prevents unwanted slippage of the vessel in the holder.

In a preferred embodiment, the recess receives the vessel up to 30%, preferably up to 25%, more preferably up to 10% of the height of the vessel. Surrounding the vessel only to a small extent reduces the amount of material that must be expended on the fixture, thereby reducing the overall production process. In addition, the exterior of the device is essentially determined by the design of the vessel, whereby the external design of the device is largely arbitrary. This allows the cost-effective production of device series of different designs, because the holder, which also contains all electronic components, is the same for all series.

In a preferred embodiment, the device has a base with an electrical connection, which has a power supply coupling for making electrical contact with the base. As a result, the device with the vessel and the holder is independent of the power connection and thus freely movable. This increases the safety of handling the device, especially if it contains hot water.

In a preferred embodiment, a light source, preferably an LED light source, is arranged in the base such that a light of the light source is visible from the outside. By the light source, the device can be illuminated, for example, to display different states of the device. Thus, the light source can indicate the operating state or the standby state of the device by different light intensity or by emitting light of different wavelengths.

In a preferred embodiment, the light source is arranged directly below the receiving platform. As a result, the light falls through the gap between base and vessel and is thus visible from the outside. If the vessel or its bottom is made of a transparent material, the light source also illuminates the interior of the vessel.

In a preferred embodiment, the heater has a temperature sensor that detects the temperature of the liquid and controls the light source so that the light source emits light as a function of the temperature of the liquid in the vessel. The light source thus serves to indicate the temperature of the liquid. For example, a change in temperature may be indicated by a change in the light intensity or a change in the emitted wavelength.

In a preferred embodiment, the base and the base each have at least one position sensor, wherein the position sensor the pedestal controls the light source so that it emits light depending on the relative radial position of the pedestal on the base. By rotating the pedestal on the base, the intensity or the color of the illumination can be changed. In addition, the position sensor and the light source may be formed so that, at a certain position of the base on the base, the color of the light changes automatically.

In a preferred embodiment, the intensity and / or the color of the illumination are stored according to the position of the pedestal on the base. This allows the lighting, after a separation of the base from the base, to assume the previously stored intensity and / or color as soon as the base is placed back on the base.

In a preferred embodiment, the light source emits visible light of different wavelengths as a function of the temperature of the liquid in the vessel.

In a preferred embodiment, the light source emits visible light of different wavelength depending on the relative radial position of the pedestal on the base.

In a preferred embodiment, the light source emits visible light of different wavelength as a function of the temperature of the liquid in the vessel until a previously defined temperature limit value has been reached. After falling below the temperature limit value, the light source emits visible light of different wavelengths as a function of the relative radial position of the base on the base.

In a preferred embodiment, the column in the closed position covers up to 20%, preferably up to 10%, more preferably up to 5% of the vessel. The column serves to anchor the vessel in the holder. It is therefore not necessary that it surrounds the vessel over a large area or even completely. By covering the column no more than 20% of the vessel, the cost of materials in the manufacture of the holder is reduced. In addition, the appearance of the device is mainly determined by the appearance of the vessel. This allows the cost-effective production of device series of different designs, because the holder can be used for all devices.

In a preferred embodiment, the column is in the closed position of the locking unit under tension. This reinforces the anchoring of the vessel in the holder, because the locking unit can only be brought into the open position against a significant resistance. This reduces the risk of unwanted loosening of the locking unit, which could cause the vessel to fall out of the holder.

In a preferred embodiment, the column is a metal band, preferably made of spring steel. In the closed position of the locking unit, the metal strip between the lid and base is stretched along the vessel and applies to this. This creates a firm and stable anchoring of the vessel in the holder. Spring steel is particularly elastic so that the column deforms despite repeated opening and closing locking.

In a preferred embodiment, the vessel further has a handle which is attached to the column. This facilitates the lifting of the device and allows the pouring of hot liquid without having to touch the vessel.

In a preferred embodiment, the column is designed as a handle. So that the vessel does not have to be touched directly during the operation of the device, the column can be made wider, for example at half the height of the vessel, so that it partially spans the vessel. Alternatively, the column may be formed so that it does not bear directly on the vessel, but protrudes at some distance from the device. In both cases, the column serves to lift and move the device.

In a preferred embodiment, the vessel is made of heat-resistant glass, preferably borosilicate glass.

In a preferred embodiment, the bottom or parts of the bottom of the vessel is made of a thermally conductive material.

In a preferred embodiment, the vessel is cylindrical and preferably the bottom of the vessel is flat. This allows a secure position of the vessel on the base and a firm anchorage in the holder. In addition, a flat bottom also allows other uses of the vessel outside of the holder. It can be used, for example, as a water jug or vase, or for storing liquids. Since the vessel can be easily cleaned and even disinfected, it can easily, if appropriate, only temporarily, be used for other uses.

In a preferred embodiment, the device is a kettle.

The invention further relates to a holder, which is designed such that in it a vessel for receiving a liquid can be used. The vessel has a bottom and a top edge of the vessel which surrounds an opening of the vessel through which the vessel is open at the top. The holder is formed by a base, a column attached to the base and upwardly extending column and a lid which is attached to a side facing away from the base end of the column. The base has on its upper side a receiving platform for placing the vessel thereon with its bottom and a heater for transferring heat to the vessel. The lid has a locking unit which can be brought into a closed position in which the lid engages in the opening of the vessel such that the vessel edge is encompassed by the lid and the upper end of the column in a vertical plane. As a result, the vessel is secured in the closed position of the locking unit of the base on the bottom, the column and the lid on the edge of the vessel in the holder. In addition, the locking unit can be brought into an open position in which the lid is disengaged from the vessel rim so that the vessel can be picked up by the receiving platform. The locking unit can be brought by pressing the lid from a closed position to an open position.

The holder may have the preferred embodiments described above.
