Abstract
The present invention application provides a bathtub. On the bathtub wall are fixed ultrasonic transmitters, and an ultrasonic transducer drive circuit is electrically connected to ultrasonic transducers. The ultrasonic transmitters further include an ultrasonic divergent structure which, after reflecting and scattering the ultrasonic waves emitted by the ultrasonic transducers, transmits the same into the bathtub (e.g., into the water of the tub).
Claims20
A bathtub comprising:
- bathtub walls and fixed ultrasonic transmitters on one or more of the bathtub walls, and an ultrasonic transducer drive circuit electrically connected to the ultrasonic transmitters;
- fixed massage jets on one or more of the bathtub walls, the massage jets being connected to a water pump or air pump;
- wherein the ultrasonic transmitters comprise ultrasonic transducers and the ultrasonic transducer drive circuit is electrically connected to said ultrasonic transducers, which are provided with electrical energy by the ultrasonic transducer drive circuit, and wherein the ultrasonic transducers operate to convert the electrical energy into ultrasonic waves;
- wherein the ultrasonic transmitters further comprise an ultrasonic divergent structure, which, after reflecting and scattering the ultrasonic waves emitted by the ultrasonic transducers, transmits the scattered ultrasonic waves into the bathtub.
1 more element
An ultrasonic transmitter for fitting to a bathtub, comprising:
- a mount for fitting the transmitter to the bathtub;
- a dish;
- an ultrasonic transducer coupled to the dish such that the ultrasonic transducer is aimed into the dish;
- wherein the dish is shaped to reflect and scatter ultrasonic waves received from the ultrasonic transducer into the interior of the bathtub when the ultrasonic transmitter is mounted to the bathtub.
1 more element
A bathtub comprising:
- at least one ultrasonic transmitter coupled to a wall of the bathtub and aimed into the wall of the bathtub;
- a dish mounted at least partially within the wall of the bathtub and configured to receive the ultrasonic waves from the ultrasonic transmitter;
- wherein the dish is a concave dish relative to the ultrasonic transmitter and is configured to catch, reflect, and scatter the received ultrasonic waves into water held by the bathtub.
