How to give internal class access to outer class properties

So, this may be an issue of what should be child of what, but I am having difficulty figuring out the best way to perform the following.

Say I have a kitchen, and I want to issue a command to turn on my toaster, so I would call something like this in a button click event:

private void buttonToaster_On_Click(object sender, EventArgs e)
{
   myKitchen.Toaster.Activate();
}

I envisioned doing what is depicted below. However, in C# it says that I have to make the RelayBoard "myStuff" a static. If for some reason I wanted to control multiple kitchens with this, I would prefer to not make this static, but how would I make it so I can instantiate a kitchen, have one relayboard that talks to everything in it, and create appliances under that kitchen that access the RelayBoard "myStuff" to write the command to?

class Kitchen
{
  RelayBoard myStuff = new RelayBoard();

  Appliance Toaster = new Appliance();
  Appliance Coffee_Maker = new Appliance();


  class Appliance
  {
     void Activate()
     {
        myStuff.WriteCommand(ApplianceAddress, 1);
     }

     void Deactivate()
     {
        myStuff.WriteCommand(ApplianceAddress, 0);
     }
  }

}

simply pass it a reference to the kitchen object:

class Appliance
{
  private Kitchen _parent;
  public Appliance(Kitchen parent) { _parent = parent; }
  void Activate()
  {
    _parent.myStuff.WriteCommand(ApplianceAddress, 1);
  }

  void Deactivate()
  {
    _parent.myStuff.WriteCommand(ApplianceAddress, 0);
  }
}
