Oven

1 . A steam oven comprising:

a heater; and

an injection nozzle comprising a nozzle member that has a fluid inlet and a first fluid outlet that is in communication with the inlet;

wherein the nozzle member is movable between: (i) a first position, in which the first fluid outlet is arranged to direct fluid towards and onto a component of the oven to be cleaned; and (ii) a second position, in which the first fluid outlet is blocked or otherwise arranged so as not to direct fluid towards and onto said component;

wherein the oven is a steam oven, the steam oven further comprising:

a second fluid outlet in communication with the inlet, wherein the second fluid outlet is open in the second position, and arranged so as to direct fluid towards the heater.

2 . The steam oven of claim 1 , further comprising:

a heating chamber for heating food in a cooking mode;

an inner chamber; and

a baffle plate that separates the heating chamber and the inner chamber;

wherein at least part of the nozzle member is located in the inner chamber.

3 . The steam oven of claim 2 , wherein the inner chamber is partially defined by the baffle plate and a rear wall opposing the baffle plate, wherein the nozzle member extends through the rear wall.

4 . The steam oven of claim 3 , wherein the component of the oven to be cleaned is the rear wall.

5 . The steam oven of claim 2 , wherein the component of the steam oven to be cleaned is the baffle plate.

6 . The steam oven of claim 1 wherein the nozzle member is configured to move between said first and second positions along an axis, and wherein the nozzle member is configured such that when it the first position it ejects fluid from the first fluid outlet at a non-orthogonal angle to said axis.

7 . The steam oven of claim 6 , wherein the non-orthogonal angle is between 80 degrees and 140 degrees.

8 . The steam oven of claim 1 , wherein the injection nozzle comprises a support,

wherein the nozzle member is moveable relative to the support, and the support comprising an actuator for moving the nozzle member between the first and second positions.

9 . The steam oven of claim 8 , wherein the support comprises a resilient biasing member acting on the nozzle member, wherein the resilient biasing member biases the nozzle member towards either the first position or the second position.

10 . The oven of claim 8 , wherein the actuator comprises a solenoid that acts on the nozzle member when it is activated so as to cause it to move between the first and second positions.

11 . The steam oven of claim 1 , configured such that when the nozzle member moves from the first position to the second position, the first outlet moves into contact with a sealing member so as to block the first outlet.

12 . The steam oven of claim 1 , further comprising:

a first container for containing water, wherein the first container is in fluid communication with the inlet; and

a second container for containing a cleaning fluid other than water, wherein the second container is selectively in fluid communication with the inlet.

13 . The steam oven of claim 1 , further comprising:

a rear wall; and

a baffle plate defining a wall of a heating compartment;

wherein the heater is arranged between the rear wall and the baffle plate; and

wherein the nozzle member extends into a space between the rear wall and the baffle plate;

wherein the second fluid outlet is for supplying water to the heater so as to generate steam, and the first fluid outlet is for supplying a fluid to the rear plate or baffle plate so as to clean it; and

wherein the nozzle member is movable between: (i) the first position, in which the first fluid outlet is arranged so as to direct a fluid towards and onto the rear plate or baffle plate; and (ii) the second position, in which the first fluid outlet is blocked or otherwise arranged so as not to direct the fluid towards and onto said rear plate or baffle plate.

14 . A method of using the steam oven as claimed in claim 1 , the method comprising:

moving the nozzle member into the first position and supplying fluid to the inlet so as to eject the fluid from the nozzle member onto the component of the oven so as to clean it; and

moving the nozzle member to the second position so as to block the first fluid outlet;

wherein, when the nozzle member is arranged in the second position, the method comprises supplying water to the inlet so as to eject water from the nozzle member onto the heater to thereby generate steam.

15 . An oven comprising:

a heating chamber for heating food in a cooking mode;

an inner chamber; and

a baffle plate that separates the heating chamber and the inner chamber;

an injection nozzle comprising a nozzle member that has a fluid inlet and a first fluid outlet that is in communication with the inlet;

wherein at least part of the nozzle member is located in the inner chamber;

wherein the inner chamber is partially defined by the baffle plate and a rear wall opposing the baffle plate, wherein the nozzle member extends through the rear wall;

wherein the nozzle member is movable between: (i) a first position, in which the first fluid outlet is arranged to direct fluid towards and onto a component of the oven to be cleaned; and (ii) a second position, in which the first fluid outlet is blocked or otherwise arranged so as not to direct fluid towards and onto said component.

16 . The oven of claim 15 , wherein the component of the oven to be cleaned is the rear wall.

17 . An oven comprising:

an injection nozzle comprising a support and a nozzle member that has a fluid inlet and a first fluid outlet that is in communication with the inlet;

wherein the nozzle member is movable between: (i) a first position, in which the first fluid outlet is arranged to direct fluid towards and onto a component of the oven to be cleaned; and (ii) a second position, in which the first fluid outlet is blocked or otherwise arranged so as not to direct fluid towards and onto said component;

wherein the nozzle member is moveable relative to the support, and the support comprising an actuator for moving the nozzle member between the first and second positions; and

wherein the support comprises a resilient biasing member acting on the nozzle member, wherein the resilient biasing member biases the nozzle member towards either the first position or the second position.

18 . The oven of claim 17 , wherein the actuator comprises a solenoid that acts on the nozzle member when it is activated so as to cause it to move between the first and second positions.
