Abstract

The invention provides a liquid supply device and a liquid discharge device capable of obtaining stable liquid discharge performance. The liquid supply device according to an embodiment is provided with a first flow path, a second flow path, a heating unit, a filter, and a bypass flow path. The first flow path is connected to a primary side of a liquid ejecting head that ejects liquid. The secondflow path is connected to the secondary side of the liquid ejecting head. The heating unit is provided in the first flow path and heats the fluid in the first flow path. The filter is arranged betweenthe heating part of the first flow path and the liquid ejecting head. The bypass flow path connects a flow path on the primary side of the filter and a flow path on the secondary side of the liquid ejecting head.

Description

technical field [0001] Embodiments of the present invention relate to a liquid supply device and a liquid ejection device. Background technique [0002] A liquid ejection device is known that includes a liquid circulation device that circulates a liquid through a circulation path that passes through a liquid ejection head that ejects the liquid. Liquids have a characteristic that their viscosity increases when the temperature is low. When the viscosity of the liquid becomes high, the liquid may not be ejected from the liquid ejection head, or the amount of liquid droplets may become unstable, and the ejection performance may be affected. [0003] In such a liquid ejection device, a heater may be provided on the primary side circulation path of the liquid ejection head in order to heat the liquid and adjust the viscosity of the liquid within a range suitable for ejection from the head. Contents of the invention [0004] The technical problem to be solved by the present in...
