2results about How to "Lower the outlet temperature" patented technology

The application belongs to the technical field of melt spinning cooling equipment, and discloses a double-layer rectification and water cooling temperature control external cooling device with adjustable air direction, which comprises a device shell installed at the air outlet of an external air blowing device, a rectification assembly comprising a first rectification member and a second rectification member, which are respectively installed on the two sides of the device shell, wherein the first rectification member is installed on the side of the device shell close to the air blowing device, and the first rectification member and the second rectification member form a double-layer rectification structure to rectify the air outlet of the air blowing device, a water cooling assembly comprising a water tank and a cooling member, the water tank stores a cooling medium and is communicated with the first rectification member to form a circulation path, which is used to cool the air passing through the first rectification member, and the cooling member is arranged on the water tank and used to cool the cooling medium in the water tank, and a control assembly installed on the device shell and used to control the air outlet temperature. The application has the advantages of good rectification effect, high cooling efficiency, adjustable temperature, stable structure, convenient disassembly and assembly, and strong adaptability.

This invention provides a method for controlling the introduction of fresh air into a washing machine and a washing machine in the field of washing machine technology. The method includes: during a drying cycle, acquiring the humidity of the external environment outside the washing drum and determining whether the humidity meets the conditions for introducing fresh air; if the humidity does not meet the conditions, controlling the fresh air introduction device to close and continuing the drying cycle; if the humidity meets the conditions, acquiring the temperature inside the washing drum and controlling the opening and closing of the fresh air introduction device based on the temperature inside the washing drum, and continuing the drying cycle. This invention introduces fresh air during the drying cycle to condense the hot and humid air inside the washing drum, further reducing the outlet air temperature of the washing drum and improving drying efficiency. Simultaneously, by detecting the ambient humidity during the introduction of fresh air, it avoids reducing drying efficiency due to insufficient humidity of the fresh air introduced into the washing drum.
