Description

Field of the Invention The present invention relates to a pump module designed to be integrated into or attached to existing dishwashers. Specifically, this invention is aimed at keeping the contents of the dishwasher moist during idle periods by intermittently spraying a fine mist of water. This ensures more efficient and thorough cleaning during the dishwasher's wash cycle while also saving time and energy. Background of the Invention Conventional dishwashers operate through a series of cycles, including pre-wash, main wash, and rinse, with periods of inactivity in between these cycles. During these idle periods, food residues on the dishes can dry out, making it more difficult to clean them effectively during the wash cycle. Additionally, prolonged idle periods before starting the dishwasher can lead to dried-on food, further reducing the efficiency of the cleaning process and increasing energy consumption. There is a need for a system that can keep the contents of the dishwasher moist during idle periods to enhance the effectiveness of the cleaning cycles and reduce energy usage. The present invention addresses this need by providing a pump module that can be added to existing dishwashers to intermittently spray a fine mist of water over the contents, thereby keeping them moist. Summary of the Invention The invention provides a pump module that can be retrofitted into existing dishwashers. This module includes a nozzle and pump system designed to intermittently spray a fine mist of water over the dishes inside the dishwasher during idle periods. The primary objectives of the invention are as follows: 1. Maintain Moisture: The fine mist keeps the dishes and food residues moist, preventing them from drying out during idle periods. 2. Improve Cleaning Efficiency: By keeping residues moist, the subsequent cleaning cycle can be more effective, reducing the need for extended wash cycles or higher temperatures. 3. Save Time and Energy: By ensuring that food residues are easier to clean, the dishwasher can operate more efficiently, saving both time and energy. 4. Easy Installation: The module is designed to be easily installed in most existing dishwashers without significant modification to the appliance. Detailed Description of the Invention 1. Construction of the Pump Module The pump module consists of the following components: • Water Reservoir: A small tank that stores water for the fine mist spray (S). This tank can be refilled manually or connected (F) to the dishwasher's water supply (T). • Pump: A compact, low-power pump (M) capable of drawing water from the reservoir and delivering it under pressure (0) to the nozzle (N). • Nozzle: A fine mist nozzle (N) designed to spray water (S) evenly over the contents of the dishwasher. The nozzle (N) is mounted inside the dishwasher cavity and is adjustable to target different areas. • Control Unit: An electronic control unit (C) that manages the operation of the pump (P) and nozzle (N). This unit can be programmed to activate the pump at specific intervals during the dishwasher's idle periods. • Power Supply: The module (M) can be powered either by the dishwasher's existing power source or through a separate battery unit (B). 2. Operation During periods of inactivity between or before dishwasher cycles, the control unit activates the pump at regular intervals. The pump draws water from the reservoir and sends it through the nozzle, which sprays a fine mist over the dishes. The control unit can be programmed to adjust the frequency and duration of the spray based on user preferences or the dishwasher's specific idle periods. 3. Installation The pump module is designed for easy installation: • The nozzle is attached inside the dishwasher using adhesive pads or screws, depending on the model of the dishwasher. • The water reservoir and pump are placed in the lower compartment or mounted on the side or back of the dishwasher. • The control unit is connected to the dishwasher's control panel or operates independently with its own power supply.
