Description

Technical Field

[0001] This invention relates to household appliances, and in particular to a fruit and vegetable cleaning machine with ozone function that utilizes ozone for sterilization and disinfection. Background Technology

[0002] Existing technologies utilize ozone to sterilize and remove pesticide residues from washed fruits and vegetables, which has a significant effect. Ozone is also widely used in fruit and vegetable washing machines. Ozone generation is based on the corona discharge method, where air is ionized to generate ozone. The ozone generator consists of a generator board, a control circuit, and an ozone generator board. The control circuit controls the ozone generator board to work, and after the air flows through the ozone generator board, some of the air generates ozone.

[0003] In existing vegetable washing machines, the ozone generator is a separate unit. To achieve ozone-containing airflow, an air pump needs to be connected to the ozone generator's air inlet. The disadvantage of using different air pumps connected to the ozone generator in existing technologies is that, due to the extreme instability of ozone, it's impossible to achieve a reasonable and precise match between the pressure, pressure stability, and flow rate of the air generated by the air pump and the ozone generator. Existing technologies use an air pump output connected to the ozone generator to deliver ozone to the water in the washing machine. However, this technology suffers from complex structure, large size, difficulty in matching the air pump with the ozone generator, resulting in low ozone generation efficiency, low ozone concentration in the gas, and high power consumption. Furthermore, ozone is ineffective at sterilizing and removing pesticide residues from washed fruits and vegetables. Summary of the Invention

The pressure gas generating chamber and the ozone generating chamber are connected by an outlet control valve. The pressure gas generating chamber is connected to the atmosphere by an inlet control valve. The ozone generating chamber is provided with an ozone exhaust port.

[0009] The ceramic piezoelectric vibrator is placed inside the pressurized gas generating chamber, forming a piezoelectric pump structure.

[0010] The ozone generating plate is disposed inside the ozone generating chamber.

[0020] The generator housing 1-1 is sealed to the upper cover 1-3 and the lower cover 1-4 of the housing, forming a dual-chamber structure consisting of a pressure gas generating chamber 1-11 and an ozone generating chamber 1-12. The pressure gas generating chamber 1-11 and the ozone generating chamber 1-12 are connected by an outlet control valve 1-6. The pressure gas generating chamber 1-11 is connected to the atmosphere by an inlet control valve 1-5. The ozone generating chamber 1-12 is provided with an ozone exhaust port 3.

[0024] The high-frequency vibration of the ceramic piezoelectric vibrator 5 in this invention generates pressurized air in the pressurized gas generation chamber 1-1, which then enters the ozone generation chamber 1-12 via the outlet control valve 1-6.

[0025] Pressurized air passes through ozone generating plate 2 in ozone generating chamber 1-12 to generate ozone, and then outputs it through ozone exhaust port 3 into the water in washing basin 4 to clean, sterilize and remove pesticide residues from fruits and vegetables in washing basin 4.
