The cleaning head may have a nozzle head whose squirt surface is curved. In the nozzle head, squirt directions of nozzles, which are arranged to fan out at a squirt angle, may be substantially perpendicular to tangents to the squirt surface. Therefore, liquid squirted from the nozzles may fly straight along the squirt directions without being drawn to the squirt surface. ## Claims ### Claim 1 A cleaning device, comprising: a cleaning head whose bottom face functions as a cleaning part; a handle supporting the cleaning head; and a squirter for squirting liquid out of the cleaning head, the squirter including a liquid jetting part mounted on or located in the vicinity of the cleaning head and a liquid supply part for supplying liquid to the liquid jetting part, the liquid jetting part having a plurality of nozzles for squirting liquid out of the cleaning head and a squirt surface where the nozzles have orifices, wherein assuming that a direction along which the cleaning head is to be moved rearward and forward during cleaning operation is a reference line and a plane which is perpendicular to the reference line in front of the squirt surface is an orthogonal plane, two nozzles are disposed with squirt directions diverging in opposite directions from the reference line to make a squirt angle with the reference line, and at individual locations where the nozzle has an orifice, the squirt surface diverges rearward from the orthogonal plane to make an opening angle with the orthogonal plane; and wherein the squirt direction of at least one of the nozzle diverges upwards from a level surface with distance from the orifice to make an elevation angle when the cleaning part is applied to the level surface to be cleaned, and the elevation angle is approximately 45° or more and 60° or less. ### Claim 2 (depends on 1) The cleaning device of claim 1, wherein another nozzle is provided with a squirt direction along the reference line. ### Claim 3 (depends on 1) The cleaning device of claim 1, wherein the squirt angle is equal or substantially equal to the opening angle. ### Claim 4 (depends on 1) The cleaning device of claim 1, wherein the squirt surface is curved and the opening angle is an opening angle between the orthogonal plane and a tangent to the squirt surface at the individual locations where the nozzle has an orifice. ### Claim 5 (depends on 1) The cleaning device of claim 1, wherein at a location where the nozzle, whose squirt direction is at the elevation angle, has an orifice, the squirt surface diverges rearward from the orthogonal plane to make an inclination angle with the orthogonal plane. ### Claim 6 (depends on 5) The cleaning device of claim 5, wherein the elevation angle is equal or substantially equal to the inclination angle. ### Claim 7 (depends on 1) The cleaning device of claim 1, wherein the liquid jetting part includes a nozzle head made of a synthetic resin and metal members assembled in the nozzle head, the nozzle head constituting the squirt surface, the nozzles being bored in the metal members, the orifices of the nozzles, as well as front faces of the metal members, being visible on the squirt surface. ### Claim 8 (depends on 1) The cleaning device of claim 1, wherein the liquid supply part includes a liquid retention part located above the liquid jetting part, a liquid passage connecting the liquid retention part and the liquid jetting part, and an interrupting mechanism for interrupting liquid supply from the liquid retention part to the liquid jetting part, wherein when the interrupting mechanism permits liquid passage, liquid retained in the liquid retention part squirts out of the nozzles by gravitation. ### Claim 9 (depends on 1) The cleaning device of claim 1, wherein the cleaning head is constructed to permit removable attachment of a cleaning sheet to the cleaning part. ### Claim 10 A cleaning device, comprising: a cleaning head whose bottom face functions as a cleaning part; a handle supporting the cleaning head; and a squirter for squirting liquid out of the cleaning head, the squirter including a liquid jetting part mounted on the cleaning head and a liquid supply part for supplying liquid to the liquid jetting part, the liquid jetting part having a plurality of nozzles for squirting liquid out of the cleaning head and a squirt surface where the nozzles have orifices, wherein assuming that a direction along which the cleaning head is to be moved rearward and forward during cleaning operation is a reference line and a plane which is perpendicular to the reference line in front of the squirt surface is an orthogonal plane, two nozzles are disposed with squirt directions diverging in opposite directions from the reference line to make a squirt angle with the reference line, and at individual locations where the nozzle has an orifice, the squirt surface diverges rearward from the orthogonal plane to make an opening angle with the orthogonal plane; and wherein the squirt direction of at least one of the nozzle diverges upwards from a level surface with distance from the orifice to make an elevation angle when the cleaning part is applied to the level surface to be cleaned, and the elevation angle is approximately 45° or more and 60° or less. ### Claim 11 A cleaning device, comprising: a cleaning head whose bottom face functions as a cleaning part; a handle supporting the cleaning head; and a squirter for squirting liquid out of the cleaning head, the squirter including a liquid jetting part mounted on or located in the vicinity of the cleaning head and a liquid supply part for supplying liquid to the liquid jetting part, the liquid jetting part having a plurality of nozzles for squirting liquid out of the cleaning head and a squirt surface where the nozzles have orifices, wherein assuming that a direction along which the cleaning head is to be moved rearward and forward during cleaning operation is a reference line and a plane which is perpendicular to the reference line in front of the squirt surface is an orthogonal plane, two nozzles are disposed with squirt directions diverging in opposite directions from the reference line to make a squirt angle with the reference line, and at individual locations where the nozzle has an orifice, the squirt surface diverges rearward from the orthogonal plane to make an opening angle with the orthogonal plane; and wherein the squirt angle is substantially equal to the opening angle. ### Claim 12 (depends on 11) The cleaning device of claim 11, wherein the squirt angle is equal to the opening angle.
