The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Fig. 1 is a schematic view showing an overall initial state of a spray arm according to the present invention.
It can be seen that the spray angle of the spray arm in the initial state of the invention is vertical to the surface of the spray arm.
As shown in fig. 2, it is a schematic view of the overall deformation state of the spray arm according to the present invention.
It can be seen that the spray angle of the spray arm under the variable state of the invention is changed to generate different spray angle changes according to the specific conditions (position, size and the like) of the set deformable material.
The spray arm structure comprises a spray arm and a nozzle arranged on the spray arm, wherein the nozzle changes the spraying direction of the nozzle according to the change of the operating state of the dishwasher, and the operating state is not limited to temperature, and can also be other operating state parameters of the dishwasher such as rotating speed, water pressure and the like.
Example one
The spray arm structure of the invention changes the spray direction of the spray nozzle according to different factors of the operating state of the dishwasher, such as temperature, water pressure, rotating speed and the like. The spray arm surface may be arranged vertically or inclined, and is not limited herein. The spray nozzle comprises a deformable material, or the spray arm is made of the deformable material, the spray nozzle changes along with factors such as temperature in the operation process of the dish-washing machine, the deformable material deforms according to the temperature, and the deformation of the spray nozzle makes the spray angle change, so that the area of the tableware washed by the single-rotation water flow is increased, and the washing efficiency of the dish-washing machine is improved.
In this embodiment, the nozzle has at least partially deformable material, for example, at least partially deformable material on the sidewall of the tubular nozzle, which deforms in response to changes in the operating conditions of the dishwasher, the deformation of the nozzle being such that a portion of the deformable material on the sidewall of the nozzle deforms, causing the tubular nozzle to shift relative to the centerline of the outlet of the spray arm, thereby changing the spray direction of the nozzle.
As shown in fig. 3, in another mode of this embodiment, the nozzle 5 protrudes from the surface of the spray arm 1, and a through hole is formed in the middle of the spray arm, i.e., a nozzle outlet. The nozzle 5 is made of deformable materials, and comprises a first deformable material 6 and a second deformable material 7, wherein the first deformable material 6 and the second deformable material 7 are two materials with different thermal expansion coefficients, and after the two materials are compounded, due to the different thermal expansion coefficients, when the temperature in the dishwasher changes, the deformation of one deformable material is larger than that of the other deformable material, so that the deformation of the nozzle is that the side wall of the nozzle is deviated relative to the central line of the water outlet of the spray arm, and the spraying direction of the nozzle is changed.
As a further optimization of the mode, the nozzle 5 adopts deformable materials comprising a first deformable material 6 and a second deformable material 7, wherein one deformable material expands when heated and the other deformable material contracts when heated, after the two deformable materials are compounded, because one material expands when heated and one material contracts when heated, when the temperature in the dishwasher changes, half of the nozzle expands when heated and half contracts when heated, the compound position of the two deformable materials deforms substantially within the elastic strain range, so that the deformation of the nozzle is caused, the offset of the side wall of the nozzle relative to the central line of the water outlet of the spray arm is larger than the angle of the former condition, and the spraying direction of the nozzle is changed.
As the further optimization of the mode, the nozzle adopts deformable materials, the nozzle comprises more than two deformable materials, the stress of the composite section is minimum according to the thermal expansion coefficient or the thermal shrinkage coefficient, and the angle which can be changed by changing the spraying direction of the nozzle is maximum.
In this embodiment, the two deformable materials of the nozzle are divided equally or unequally along the axial plane and parallel to the axial plane, or the joint surfaces of the two deformable materials and the nozzle axis form a certain included angle, and the included angle can be adjusted according to the characteristics of the deformable materials, so that the changeable angle of the spraying direction of the nozzle is the largest on the premise that the strength of the joint surfaces is large enough.
Or, as another form of this embodiment, the spray arm 1 includes an upper and a lower two-part structure, the upper and the lower two-part structure are made of deformable materials with different thermal expansion coefficients, and due to the different thermal expansion coefficients, when the temperature in the dishwasher changes, the deformation of one deformable material is greater than that of the other deformable material, so that the whole spray arm is bent and deformed, and is arched upwards or downwards, the axis of the nozzle outlet is perpendicular to the surface of the spray arm, and due to the bending of the upper and the lower surfaces of the spray arm, the side wall of the nozzle is offset relative to the original center line of the nozzle outlet, so as to change.
As a further optimization of the mode, the material of the upper and lower two-part structure of the spray arm 1 is a deformable material which expands when heated and contracts when heated, and the two deformable materials are compounded. Because one material is heated to expand and the other material is heated to contract, when the temperature in the dish-washing machine changes, one deformable material is heated to expand and the other deformable material is heated to contract, the composite position of the two deformable materials deforms within the elastic strain range, so that the whole spray arm is bent and deformed, the upper arch or the lower arch is concave, the axis of the water outlet of the nozzle 5 is vertical to the surface of the spray arm, and the side wall of the nozzle deviates relative to the original central line of the water outlet of the nozzle due to the bending of the upper surface and the lower surface of the spray arm, so that the spraying direction of the.
As the further optimization of the mode, the spray arm 1 adopts deformable materials, the deformable materials are more than two deformable materials, the stress of the composite section is minimum according to the thermal expansion coefficient or the thermal shrinkage coefficient, and the angle of the spraying direction of the spray nozzle can be changed to be maximum.
As shown in fig. 4 to 11, the second embodiment of the present invention is in an initial and deformed state.
Example two
The spray arm structure comprises a spray arm and a nozzle arranged on the spray arm. The initial state of the water jet direction of the nozzle can be set to be vertical to the surface of the spray arm, and can also be set to be inclined to the surface of the spray arm, which is not limited herein. The spray arm structure further comprises an adjusting part, the spraying direction of the spray nozzle is directly or indirectly adjusted through the adjusting part, and the adjusting part at least comprises a deformable material which deforms according to the change of the operating state of the dishwasher. The nozzle is installed on flexible base, and the dish washer during operation sprays the arm rotation to realize the circumference formula spray rinsing. Along with dish washer water is heated, temperature in the dish washer risees gradually, and deformable material produces deformation in the regulating part, and one end is blockked by supporting mechanism, and the nozzle slope can be oppressed to deformable material deformation back to the injection angle has been adjusted.
Furthermore, all the adjusting parts can be provided with deformable materials with different structures, and due to different structures, although the deformation coefficients are consistent, the deformation generated under the same temperature change is different; materials with the same size and different heat capacities can be adopted, and because the materials are different, the sizes of the generated thermal deformation are different, and the structural sizes and the materials can also be different; thus, the spray angle of each nozzle varies differently, in this way, more preferably, in a direction away from the axis of rotation of the spray arm, a deformable material is provided with a greater variation of the spray angle, while a position close to the centre of the axis of the spray arm, a deformable material with a smaller variation of the spray angle, which allows a greater and more concentrated coverage of the space inside the cleaning chamber of the dishwasher.
Furthermore, the nozzle is arranged on the flexible base, the deformable material in the adjusting component is arranged on one side of the outer side of the radial side wall of the nozzle and provides a stress supporting position through the supporting mechanism, and when the internal temperature changes, the deformable material deforms, so that the nozzle is inclined along the deformation changing direction by taking the flexible base as the support, and the spraying angle is changed. More preferably, the deformable material in the adjustment member is disposed outside the radial sidewall of the nozzle adjacent the nozzle outlet. Because the deformable material setting position is far away from the flexible base support position, the relative arm of force is longer, so, under the condition of the same deformation displacement, the limit angle of the water flow sprayed by the nozzle is larger.
On the other hand, the nozzle is arranged on the flexible base, the deformable material in the adjusting component is arranged on any side of the axial water inlet of the nozzle, and a stress supporting position is provided by the supporting mechanism, when the internal temperature changes, the deformable material deforms, the nozzle is enabled to incline by taking the flexible base as the support through the supporting mechanism, and therefore the spraying angle is changed, which is equivalent to the principle of utilizing a lever structure. More preferably, the variable material in the adjustment member is disposed on either side of the nozzle axial water inlet, and away from the nozzle axis. Because the deformable material is far away from the flexible base supporting position, the moment arm of the deformable material is relatively long, and therefore the limit angle of the water flow sprayed by the nozzle is larger under the condition of the same deformation displacement.
The flexible base that further nozzle bottom set up can be one section bellows, and the bellows produces one side compression along with nozzle angle change back, and one side is tensile, and rivers then are normal pass through the bellows and reach the nozzle and spray. More preferably, the bellows is sleeved with a spring, and when the deformation of the deformable material in the adjusting part brings about a corresponding deformation of the bellows, the bellows cannot be restored to the initial state by the elasticity of the bellows, and the bellows is restored to the initial spraying angle of the nozzle by the elasticity of the spring.
As shown in fig. 4 and 6, the spray arm of the present invention includes a spray arm 1 and a nozzle 5 disposed on the spray arm. The initial state of the water jet direction of the nozzle 5 is vertical to the surface of the spray arm 1. The adjusting part 4 comprises a deformable material, the spray nozzles 5 are mounted on the flexible base 2, and the spray arm 1 rotates to realize circumferential spray-washing when the dishwasher is in operation. As shown in fig. 4 and 6, the spray arm of the present invention is in a deformed state. Along with the dish washer water is heated, the temperature in the dish washer produces the change, and nozzle 5 is heated deformation because of the deformation material in adjustable part 4, and the one end locking of deformable material is in supporting mechanism 3, and deformable material deformation produces to the deformation displacement of other end, oppresses nozzle 5 slope to the injection angle has been adjusted.
As shown in fig. 8 and 10, the spray arm of the present invention includes a spray arm 1 and a nozzle 5 provided on the spray arm in an initial state. The initial state of the water jet direction of the nozzle 5 is vertical to the surface of the spray arm 1. The adjusting part 4 comprises a deformable material, the spray nozzles 5 are mounted on the flexible base 2, and the spray arm 1 rotates to realize circumferential spray-washing when the dishwasher is in operation. As shown in fig. 8 and 10, the spray arm of the present invention is in a deformed state. Along with dish washer water is heated, temperature in the dish washer rises gradually, and nozzle 5 is heated deformation because of the deformable material in adjusting part 4, and deformable material stops in spray arm 1 surface, and the deformable material setting in adjusting part 4 is in one orientation connection supporting mechanism 3 in the radial outside of nozzle 5, rises when inside temperature, deformable material is heated deformation and is promoted supporting mechanism 3, makes nozzle 5 use flexible base 2 to support through supporting mechanism 3 and makes nozzle 5 produce the slope to change injection angle.
Furthermore, all the nozzles 5 can be provided with variable materials in the adjusting parts 4 with different sizes, and due to different material sizes, although the thermal deformation coefficients are consistent, the deformation sizes are different; materials with the same size and different deformation quantities can be adopted, and because the materials are different, the generated thermal deformation is different in size; thus, the spray angle of each nozzle 5 varies differently, in this way, more preferably, a deformable material with a greater variation of the spray angle is provided in a direction away from the axis of rotation of the spray arm 1, while a deformable material with a smaller variation of the spray angle is provided close to the central position of the axis of the spray arm, which allows a greater and more concentrated coverage of the space inside the cleaning chamber of the dishwasher.
Or as shown in fig. 4 to 11, further: the flexible base may be a length of corrugated tubing. The flexible base 2 arranged at the bottom of the nozzle 5 can be a section of corrugated pipe, after the corrugated pipe changes along with the angle of the nozzle, one side of the corrugated pipe is compressed, one side of the corrugated pipe is stretched, and water flow is normally transmitted to the nozzle 5 through the corrugated pipe to be sprayed. More preferably, the bellows is sleeved with a spring, and when the deformation of the deformable material in the adjusting part 4 brings the displacement deformation of the bellows and cannot be restored to the initial state by the elasticity of the bellows, the bellows is restored to the initial spraying angle of the nozzle 5 by the elasticity of the spring.
It is worth pointing out that, in this embodiment, that is, the nozzle is installed on the flexible base, the operation state may be a rotation speed and a water pressure (in an actual product, the rotation speed is controlled by the water pressure, that is, the water pressure is high, the rotation speed is high, and the nozzle is inclined away from the rotation axis by taking the flexible base as a pivot under the centrifugal force generated by the rotation of the spray arm, that is, the spray angle of the nozzle is changed, and when the rotation speed is higher, the generated centrifugal force is higher, and the corresponding spray angle change is also higher.
