Definitions

  • the invention relates to a flow controller for a hot water appliance and to a hot water appliance, more particularly a high-power hot water appliance, provided with such a flow controller.
  • Such high-power hot water appliances are for instance applied to supply hot channel water to a tap in a kitchen or to provide hot water to showers.
  • the use of such (high-power) hot water appliances presents several challenges.
  • hot water appliances for such facilities are cascaded, i.e. connected to each other in a parallel circuit. According to the requirement, one or more hot water appliances are coupled or uncoupled by means of shut-off valves.
  • the invention now has for its object to provide a flow controller and a hot water appliance of the above described type provided therewith which overcomes at least one of the stated challenges.
  • a flow controller for a hot water appliance comprising:
  • - a housing comprising at least three channels
  • a branching chamber which is arranged in the housing and in which the at least three channels debouch and in which a shut-off valve is arranged with which at least two of the three channels can be closed and left clear;
  • shut-off valve has an adjustment range with a first extreme position in which a first channel and a second channel of the at least three channels arc in flow connection with each other via the branching chamber and in which the first channel and a third channel of the at least three channels are substantially closed off from each other.
  • the shut-off valve When in the case of such a flow controller the shut-off valve is moved away from the first extreme position, the closure between the first and third channels is gradually opened, whereby fluid can flow via the branching chamber into the third channel.
  • the flow controller can hereby allow selective flow of fluid via the third channel while the first and second channels can remain in flow connection with each other via the branching chamber.
  • a flow controller which can temporarily guide a part of the fluid via a bypass conduit.
  • the shut-off valve lies in the first extreme position against the wall of the branching chamber and closes off the third channel from the branching chamber, while a fluid can however flow via the branching chamber from the first channel to the second channel, or vice versa.
  • the third channel is on the one hand effectively closed while throughflow of fluid from the first channel via the branching chamber to the second channel, or vice versa, can take place substantially unobstructed.
  • the shut-off valve comprises two sealing sides, wherein:
  • a first scaling side of the shut-off valve lies against the wall of the branching chamber and closes off the third channel from the branching chamber;
  • a second sealing side of the shut-off valve lies against the wall of the branching chamber and closes off the first channel from the branching chamber, whereby the supply of fluid via the first channel to the branching chamber is substantially blocked.
  • shut-off valve By providing the shut-off valve with two sealing sides, each configured to provide a seal in an associated extreme position, two opposite outflows of channels, an outflow of the first channel and an outflow of the third channel respectively, can be closed off from the branching chamber with one shut-off valve.
  • a flow controller which in the second extreme position can temporarily block a supply of fluid via the first channel.
  • the flow controller can hereby temporarily uncouple a hot water appliance from a parallel circuit, this providing a solution to the second challenge stated in the introduction. It is noted that the flow controller according to this embodiment with a single shut-off valve provides a solution to the first and second challenges stated in the introduction, while at least two separate shut-off valves were necessary for this purpose in the prior art.
  • This embodiment moreover provides a greatly simplified control: the channels are opened and closed in predictable manner by moving the shut-off valve at a predetermined speed from the one extreme position to the other extreme position. From the second extreme position to the first extreme position the bypass conduit is only opened temporarily and it is possible to determine in advance how much fluid is admitted via the third channel to the bypass conduit. A desired characteristic for the throughflow can be achieved with the design of the channel around the shut- off valve.
  • the first, second and third channels are at least largely, more preferably substantially fully closable in the second extreme position of the adjustment range of the shut-off valve.
  • some leakage flow may continue between the first channel and the second channel, and this can even be desirable.
  • a small leakage flow of cold water through a first - at that moment not heating - hot water appliance can thus be easily compensated by having a second hot water appliance heat the water slightly more so that the mixture from the hot water appliances in parallel connection supplies water at the desired water temperature.
  • By maintaining a small leakage flow large pressure differences, which exert load on the shut-off valve and other parts, can be prevented. It therefore suffices for some applications that the throughflow between the first and second channels can be at least greatly reduced, or 'constricted' .
  • first, second and third channel may be substantially fully closable with the shut-off valve. Because a 'constricted' position can likewise be set therewith, this embodiment which can achieve full closure is recommended.
  • the shut-off valve moves in the branching chamber between the first and second extreme positions substantially transversely of the outflow of the second channel, and this outflow of the second channel into the branching chamber is left clear by the shut-off valve.
  • the shut-off valve can hereby close off two opposite outflows of channels, an outflow of the first channel and an outflow of the third channel respectively, from the branching chamber while the second channel remains in connection with the branching chamber over this adjustment range.
  • the first, second and third channels are brought into flow connection with each other over a first part of the adjustment range during movement thereover from the second extreme position in the direction of the first extreme position, and their relative flow via the branching chamber is increased over the adjustment range away from the second extreme position.
  • the throughflow between the first channel and the second channel is hereby controllable and can be reduced, or 'constricted' , when required. In the case of a high pre-pressure of the water it is thus possible to prevent so rapid a flow through the appliance that the outflow temperature desired by the user cannot be achieved. By reducing the throughflow in such a case it is possible to guarantee that the desired outflow temperature of the water is attainable.
  • a sub-flow of fluid simultaneously also runs via the branching chamber to the third channel.
  • the first, second and third channels are in flow connection with each other over a second part of the adjustment range and the throughflow via the branching chamber between the first and the second channel is further increased over the further adjustment range in the direction of the first extreme position, while the throughflow via the branching chamber between the first and the third channel is decreased over the further adjustment range in the direction of the first extreme position.
  • the throughflow between the first channel and the second channel is hereby further controllable, while on the other hand the flow of fluid from the branching chamber to the third channel in the second part of the adjustment range can be reduced, and even fully closed off.
  • the transition between the first part of the adjustment range and the second part of the adjustment range lies in the range of 35 -65 , and more preferably in the range 40%-60% of the adjustment range of the shut-off valve.
  • the heat exchanger becomes more powerful, it will also be desirable to be able to supply more cold water via the bypass conduit.
  • a bypass in the above stated range is sufficient for the most common (high-power) hot water appliances.
  • the volume flow from the first channel is divided at the transition between the first part of the adjustment range and the second part of the adjustment range substantially proportionally over the second and the third channel.
  • shut-off valve of the flow controller is adjustable via a drivable screw spindle, a reliable and properly controllable system is obtained.
  • the screw spindle is provided with a pitch and, in combination with the rotatable driving of the spindle, an accurate movement of the shut-off valve can be realized.
  • the driving can for instance take place with an electric motor, more particularly with a stepping motor.
  • the shut-off valve is manufactured according to yet another preferred embodiment from a corrosion-resistant metal, more preferably from brass.
  • the invention further relates to a hot water appliance, comprising:
  • the first channel is a feed channel
  • the second channel is a first discharge channel which is in flow connection with the inlet channel of the heat exchanger
  • the third channel is a second discharge channel which is in flow connection with a bypass channel
  • bypass channel is in flow connection with the outlet channel of the heat exchanger so that, depending on a position of the shut-off valve in the branching chamber of the flow controller, water from the outlet channel of the heat exchanger and the bypass channel is mixable and dischargeable in mixed state via a water outflow of the hot water appliance.
  • the heat of the heat exchanger can have via temperature changes an adverse effect on the temperature changes on the sealing of the shut-off valve of the flow controller, and more limescale formation will moreover take place on the hot side, it is nevertheless possible to envisage that for specific applications the flow controller will be mounted on the hot side of the heat exchanger. Because the flow controller is located closer to the outlet of the heat exchanger, the cold water need cover less distance and a direct control can therefore be realized. It is noted that the branching chamber functions here as mixing chamber. According to an alternative
  • the invention therefore also relates to a hot water appliance comprising:
  • the first channel is a discharge channel
  • the second channel is a feed channel which is in flow connection with the outlet channel of the heat exchanger
  • the third channel is a feed channel which is in flow connection with a bypass channel
  • bypass channel is in flow connection with the outlet channel of the heat exchanger so that, depending on a position of the shut-off valve of the flow controller, water from the outlet channel of the heat exchanger and the bypass channel is mixable in the branching chamber and dischargeable in mixed state via a water outflow of the hot water appliance.
  • the hot water appliance further comprises at least one temperature sensor for determining the temperature of the water leaving the heat exchanger, and an electronic controller configured to drive the shut-off valve subject to the water temperature using a drive means, more particularly an electric motor.

  • the motionless hot water in heat exchanger 4 can reach undesirably high temperatures. If hot water is drawn off again shortly thereafter, this water can have become so hot that it causes a risk of burn injury when it comes into contact with the skin of a user.
  • Hot water appliance 2 is provided with a bypass channel 10 with which cold water can be guided directly to outlet channel 8 of hot water appliance 2.
  • This cold water can be admixed here to hot water coming from hot water appliance 2.
  • cold water can thus be briefly admixed to the hot water in outlet channel 8, thereby preventing this water from being delivered at an undesirably high temperature to a user.
