Abstract
A hose nozzle assembly which is capable of heating water comprising an internal heating chamber with at least one heating element. The hose nozzle assembly is able to heat water from a common garden hose with the ability to control both flow rates and temperature.
Claims17
A hose nozzle assembly comprising:
- a handheld enclosure having a handle portion and a body portion, the handle portion connected to the body portion and adapted to be gripped by a user;
- a heating chamber housed within the body portion and comprising an inlet, an outlet, and a bare wire heating element, the bare wire heating element configured to heat a fluid flowing through the heating chamber;
- a heating chamber inlet temperature sensor positioned at the inlet and configured to detect a temperature of the fluid at the inlet;
- a heating chamber outlet temperature sensor positioned at the outlet and configured to detect a temperature of the fluid at the outlet;
- a flow sensor, housed within the handheld enclosure, the flow sensor configured to detect a flow of the fluid through the heating chamber;
- a control board, the control board housed within the handheld enclosure and in communication with the heating chamber inlet temperature sensor, the heating chamber outlet temperature sensor, and the flow sensor, the control board configured to control a heat output by the bare wire heating element to heat the fluid based on data received from the heating chamber inlet temperature sensor, the heating chamber outlet temperature sensor, and the flow sensor;
- a spray nozzle connected to the body portion and configured to direct a flow of fluid from the body portion;
- a fluid inlet associated with the handle portion and adapted for attachment to a hose;
- a valve in fluid communication with the fluid inlet for controlling the flow of fluid;
- and
- a valve trigger for controlling the valve.

- a handheld enclosure having a handle portion and a body portion, the handle portion connected to the body portion and adapted to be gripped by a user;
- an electrical power connection, the electrical power connection being connected to the handheld enclosure;
- a heating chamber housed within the body portion, the heating chamber comprising an inlet, an outlet, and a heating element, the heating element configured to heat a fluid flowing through the heating chamber;
- an inlet temperature sensor positioned at the inlet and configured to detect a temperature of the fluid at the inlet;
- a flow sensor, housed within the handheld enclosure, the flow sensor configured to detect a flow of a fluid through the heating chamber;
- a spray nozzle connected to the body portion and configured to direct a flow of a fluid from the body portion;
- and
- a control board, housed within the handheld enclosure, wherein the control board is configured to receive data from the inlet temperature sensor and the flow sensor and control a heat output by the heating element to heat the fluid based on a predetermined temperature set point and data received from the inlet temperature sensor and the flow sensor.
