Description

Technical Field

[0001] The present invention relates to the technical field of dishwashing equipment, in particular to a drawer-type dishwasher. Background Art

[0002] As a new type of dishwasher, the drawer-type dishwasher is embedded in the cabinet, has a compact structure, and can be operated without squatting or bending over, compared to the pull-down door dishwasher, which allows users to have a better user experience. For household dishwashers, due to the limitation of its installation space, the volume and power of the water pump used to supply water to the spray pipe of the drawer-type dishwasher are limited, resulting in that its spray pipe can only be set at the bottom of the inner tank of the drawer-type dishwasher close to the water pump, so that the spray pipe sprays upward to clean the tableware. However, due to the uncertainty of the placement, shape, size, etc. of the tableware, spraying upward to clean the tableware is very likely to cause the tableware to have dead corners for spray cleaning, and residual food residues, resulting in poor spray cleaning effect of the drawer-type dishwasher.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a drawer-type dishwasher. The water output from the water pump is transported upward and sprayed in three dimensions through a spray pipeline, so that the drawer-type dishwasher can perform three-dimensional spray cleaning from the open part downward, avoiding dead corners in the spray cleaning of the drawer-type dishwasher and achieving a better spray cleaning effect of the drawer-type dishwasher.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] The present invention provides a drawer-type dishwasher, comprising:

[0007] A drawer, wherein a cavity is formed inside for placing tableware;

[0008] The spray pipeline extends upward from the bottom of the cavity to the opening close to the cavity, and then extends along the circumference of the opening. The portion of the spray pipeline extending along the circumference of the opening is provided with a plurality of water outlets for spraying toward the interior of the cavity.

[0009] The present invention realizes that the drawer-type dishwasher can perform three-dimensional spray cleaning from the opening downward, avoiding dead corners in the spray cleaning of the drawer-type dishwasher and achieving a better spray cleaning effect of the drawer-type dishwasher, by extending the spray pipeline upward from the bottom of the cavity and extending along the circumference of the opening, and providing a plurality of water outlets for spraying toward the interior of the cavity.

[0010] A further solution of the present invention is: the spray pipeline comprises:

[0011] A first pipeline extends upward from the bottom of the cavity to a position close to the opening of the cavity, then extends in a direction parallel to a second side of the opening, and then extends in a direction parallel to a third side of the opening;

[0012] A second pipeline extends upward from the bottom of the cavity to a position close to the opening of the cavity, and then extends in a direction parallel to the first side of the opening;

[0013] The first side of the opening is parallel to the third side, and the second side is connected to the first side and the third side respectively;

[0014] The water outlet is arranged at a portion of the second pipeline extending along the first side edge, and a portion of the first pipeline extending along the second side edge and the third side edge.

[0015] In the above scheme, by setting the first pipeline and the second pipeline, the drawer-type dishwasher can perform spray cleaning with different spray intensities on the three open sides, which better meets the spray cleaning needs of different types of tableware in the drawer-type dishwasher.

[0016] A further solution of the present invention is: the spray pipeline comprises:

[0017] A first pipeline extends upward from the bottom of the cavity to a position close to the opening of the cavity, then extends in a direction parallel to the second side of the opening, and then extends in a direction parallel to the third side of the opening;

[0018] A third pipeline extends upward from the bottom of the cavity to a position close to the opening of the cavity, then extends in a direction parallel to a fourth side of the opening, and then extends in a direction parallel to the third side of the opening relative to the first pipeline;

[0019] The second side of the opening is parallel to the fourth side, and the third side is connected to the second side and the fourth side respectively;

[0020] The water outlet is arranged at a portion of the first pipeline extending along the second side and the third side, and at a portion of the second pipeline extending along the third side and the fourth side.

[0021] In the above scheme, by providing the first pipeline and the third pipeline, the drawer-type dishwasher can be spray-cleaned evenly on the three exposed sides, thereby making the area for spray-cleaning inside the inner tank of the drawer-type dishwasher larger.

[0022] A further solution of the present invention is that the first pipeline extends to an opening close to the cavity, then bends 90 degrees with a rounded corner and extends horizontally to the intersection of the first side and the second side, bends 90 degrees again and extends in close contact with the side wall of the cavity.

[0023] In the above scheme, by bending the fillet 90 degrees and bending again 90 degrees and extending to fit the side wall of the cavity, the hydraulic loss of water flow is reduced and the spray pipeline occupies less space in the cavity.

[0024] A further solution of the present invention is: a connecting device is arranged on the inner surface of the cavity, the spray pipeline is connected to the connecting device, and the spray pipeline is extended to fit the inner surface of the cavity;

[0025] And / or, a mounting groove is recessed on the inner wall of the cavity, and the spray pipeline is at least partially installed inside the mounting groove.

[0026] In the above solution, the portion of the spray pipeline where the water outlet is arranged occupies less space in the cavity through the connecting device and / or the mounting groove.

[0027] A further solution of the present invention is: a water pressure chamber, which is connected to the water inlet end of the spray pipeline, comprises an annular water inlet, a first baffle tongue and a second baffle tongue, wherein a water flow channel connected to the annular water inlet is formed between the first baffle tongue and the second baffle tongue;

[0028] The first baffle tongue and the second baffle tongue are respectively bent and extended from a position close to the annular water inlet, and then extend along a straight line to the water outlet of the water pressure chamber.

[0029] In the above scheme, the water flow is pressurized through the annular water inlet, the first baffle tongue and the second baffle tongue of the water pressure chamber, and the first baffle tongue and the second baffle tongue are arranged in a manner that the occupied area of ​​the first baffle tongue and the second baffle tongue is smaller, while meeting the needs of water flow pressurization for upward transportation and three-dimensional spraying of the drawer-type dishwasher, and the overall structure of the water pressure chamber is smaller.

[0030] A further solution of the present invention is: two first partition tongues, two second partition tongues, and a first connecting portion and a second connecting portion;

[0031] A first water flow channel is formed between one of the first partition tongues and one of the second partition tongues, and a second water flow channel is formed between another first partition tongue and another second partition tongue;

[0032] The two ends of the first connection portion are respectively connected to form two first partition tongues of the first water flow channel and the second water flow channel, and the two ends of the second connection portion are respectively connected to form two second partition tongues of the first water flow channel and the second water flow channel;

[0033] The first connection part and the second connection part partially fit the annular water inlet, and then bend and extend radially of the annular water inlet. The parts of the first connection part and the second connection part that fit the annular water inlet are symmetrically arranged along the center of the annular water inlet.

[0034] In the above scheme, the flow rates in the first water flow channel and the second water flow channel are made equal through the first partition tongue, the second partition tongue, the first connecting part and the second connecting part, so that the two connected spray pipes can achieve uniform spraying.

[0035] A further solution of the present invention is that the water pressure chamber further comprises: a first water outlet pipe and a second water outlet pipe;

[0036] The first baffle tongue and the second baffle tongue extend and are inserted into the first water outlet pipe and the second water outlet pipe, so that the first water flow channel is connected to the water outlet of the first water outlet pipe, and the second water flow channel is connected to the water outlet of the second water outlet pipe;

[0037] The first water outlet pipe and the second water outlet pipe are extended in a straight line and / or in a curved direction from the opening of the cavity of the water pressure chamber, and the extension directions of the first water outlet pipe and the second water outlet pipe are not collinear.

[0038] In the above scheme, the first water outlet pipe and the second water outlet pipe are not colinear in their extension direction, so that the first baffle tongue and the second baffle tongue can be bent and extended to be inserted into the first water outlet pipe and the second water outlet pipe, thereby reducing the kinetic energy loss of the water flow rotation motion.

[0039] A further solution of the present invention is that the water pressure chamber further includes an annular shell;

[0040] The annular water inlet is arranged on the inner peripheral wall of the annular shell, the first baffle tongue and the second baffle tongue are arranged inside the annular shell, and the outer peripheral wall of the annular shell is connected to the first water outlet pipe and the second water outlet pipe.

[0041] In the above scheme, an annular water inlet is arranged in the annular housing so that it can be directly connected with the water pump or the impeller, thereby reducing hydraulic loss and ensuring that the water flow entering the water pressure chamber has sufficient hydraulic force.

[0042] A further solution of the present invention is: the drawer-type dishwasher further comprises: a first connecting member and a second connecting member;

[0043] One end of the first connecting member is connected to the water pressure chamber, and the other end is connected to the second connecting member;

[0044] The second connecting piece is communicated with the spray pipeline.

[0045] In the above scheme, the water flow in the water pressure chamber is more directly sent to the spray pipeline through the first connecting member and the second connecting member, thereby reducing hydraulic loss.

[0046] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0047] 1. The water from the water pump is transported upward and sprayed in three dimensions through the spray pipeline, and the hydraulic loss is reduced in the process, so that the drawer-type dishwasher can be sprayed and cleaned in three dimensions from the open part downward, avoiding the dead corners of the spray cleaning of the drawer-type dishwasher and achieving a better spray cleaning effect of the drawer-type dishwasher;

[0048] 2. By setting the spray pipe, it occupies less space in the cavity of the drawer-type dishwasher;

[0049] 3. The water flow is pressurized through the water pressure chamber to meet the water flow pressurization requirements for upward transportation and three-dimensional spraying of the drawer-type dishwasher.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0065] like Figures 1 to 8 As shown, the present invention provides a drawer-type dishwasher. The drawer-type dishwasher pressurizes, transports upward and sprays three-dimensionally the water output by the water pump through the water pressure chamber 2, the first connecting member 3, the second connecting member 4 and the spray pipeline 1, so that the drawer-type dishwasher can perform three-dimensional spray cleaning downward from the opening 52, thereby achieving a better spray cleaning effect of the drawer-type dishwasher.

[0066] Embodiment 1

[0067] like Figures 1 to 6 As shown, this embodiment provides a drawer-type dishwasher, comprising:

[0068] A drawer, wherein a cavity is formed inside for placing tableware;

[0069] The spray pipe 1 extends upward from the bottom of the cavity to an opening 52 close to the cavity, and then extends along the circumference of the opening 52. The portion of the spray pipe 1 extending along the circumference of the opening 52 is provided with a plurality of water outlets 15 for spraying toward the interior of the cavity.

[0070] Specifically, in this embodiment, Figure 2 As shown, the surrounding and bottom of the cavity are inner liner walls 51.

[0071] By extending the spray pipe 1 upward from the bottom of the cavity, extending along the circumference of the opening 52, and providing a plurality of water outlets 15 for spraying toward the interior of the cavity, the drawer-type dishwasher can perform three-dimensional spray cleaning downward from the opening 52, avoiding dead corners in the spray cleaning of the drawer-type dishwasher and achieving a better spray cleaning effect of the drawer-type dishwasher.

[0072] In this embodiment, Figure 2 and 3 As shown, the spray pipeline 1 includes: a first pipeline 11, extending upward from the bottom of the cavity to a position close to the opening 52 of the cavity, and then extending in a direction parallel to the second side of the opening 52, and then extending in a direction parallel to the third side of the opening 52; a second pipeline 12, extending upward from the bottom of the cavity to a position close to the opening 52 of the cavity, and then extending in a direction parallel to the first side of the opening 52; wherein the first side of the opening 52 is parallel to the third side, and the second side is connected to the first side and the third side respectively; the water outlet 15 is arranged at the portion of the second pipeline 12 extending along the first side, and the portion of the first pipeline 11 extending along the second side and the third side.

[0073] In detail, different types of tableware have different spray cleaning requirements, so the first pipeline 11 and the second pipeline 12 are set asymmetrically. For example, ceramic dishes are large in shape and stains are easy to clean, so they are set at the first pipeline 11; cups and small dinner plates are small in shape and prone to stubborn stains, so they are set at the second pipeline 12. Therefore, through the setting of the first pipeline 11 and the second pipeline 12, the drawer-type dishwasher can perform spray cleaning with different spray intensities on the three sides of the opening 52, which better meets the spray cleaning requirements of different types of tableware in the drawer-type dishwasher.

[0074] In this embodiment, Figure 1 , 2As shown in FIG. 3 , the first pipeline 11 extends to the opening 52 close to the cavity, then bends 90 degrees with a rounded corner and extends horizontally to the intersection of the first side and the second side, bends 90 degrees again and extends in line with the side wall of the cavity.

[0075] Specifically, the second pipeline 12 extends to the opening 52 close to the cavity, and then is rounded and bent by 90 degrees to extend in contact with the side wall of the cavity.

[0076] In this embodiment, the drawer-type dishwasher further includes a connecting device, which is disposed on the inner surface of the cavity, and the spray pipe 1 is connected to the connecting device, so that the spray pipe 1 extends in contact with the inner surface of the cavity.

[0077] Specifically, the connecting device can be a plurality of small hooks, which are fixed on the inner wall of the inner tank of the drawer-type dishwasher, and the bends of the small hooks are engaged with the lower surface of the spray pipe 1 .

[0078] Therefore, through the connection device, the portion of the spray pipe 1 where the water outlet 15 is arranged occupies less space in the cavity.

[0079] Specifically, the surroundings and bottom of the cavity are the inner liner wall 51. The cavity is formed by the inner liner wall 51. During the process of the first pipeline 11 and the second pipeline 12 vertically extending to the opening 52 close to the cavity, they are also in contact with the cavity wall, that is, the inner liner wall 51.

[0080] Specifically, Figure 2 As shown, the second pipeline 12 extends in a direction parallel to the first side of the opening 52 to a point beyond the center line of the cavity.

[0081] In this embodiment, Figure 1 and 6 As shown, the drawer-type dishwasher also includes a water pressure chamber 2, which is connected to the water inlet end of the spray pipe 1, including an annular water inlet 26 and at least a pair of partition tongues 28, wherein the pair of partition tongues 28 specifically include a first partition tongue 281 and a second partition tongue 282, and a water flow channel connected to the annular water inlet 26 is formed between the first partition tongue 281 and the second partition tongue 282; the first partition tongue 281 and the second partition tongue 282 are respectively bent and extended from near the annular water inlet 26, and extend in a straight line to the water outlet 15 of the water pressure chamber 2.

[0082] The water flow is pressurized through the annular water inlet 26, the first baffle tongue 281 and the second baffle tongue 282 of the water pressure chamber 2. The first baffle tongue 281 and the second baffle tongue 282 are arranged in a manner that the occupied area of ​​the first baffle tongue 281 and the second baffle tongue 282 is smaller, and the overall structure of the water pressure chamber 2 is smaller, while meeting the needs of water flow pressurization for upward transportation and three-dimensional spraying of the drawer-type dishwasher.

[0083] In this embodiment, Figure 6 As shown, two first partition tongues 281, two second partition tongues 282, and a first connecting portion 261 and a second connecting portion 262; a first water flow channel is formed between one of the first partition tongues 281 and one of the second partition tongues 282, and a second water flow channel is formed between the other first partition tongue 281 and the other second partition tongue 282; the two ends of the first connecting portion 261 are respectively connected to form two first partition tongues 281 of the first water flow channel and the second water flow channel, and the two ends of the second connecting portion 262 are respectively connected to form two second partition tongues 282 of the first water flow channel and the second water flow channel; the first connecting portion 261 and the second connecting portion 262 partially fit the annular water inlet 26, and then bend and extend toward the radial direction of the annular water inlet 26, and the parts of the first connecting portion 261 and the second connecting portion 262 that fit the annular water inlet 26 are symmetrically arranged along the center of the annular water inlet 26.

[0084] The first partition tongue 281, the second partition tongue 282, the first connection part 261 and the second connection part 262 make the water flow in the first water flow channel and the second water flow channel equal, so that the two connected spray pipes 1 can achieve uniform spraying.

[0085] In this embodiment, Figure 6 As shown, the water pressure chamber 2 also includes: a first water outlet pipe 22 and a second water outlet pipe 27; a first baffle tongue 281 and a second baffle tongue 282 extend and insert into the first water outlet pipe 22 and the second water outlet pipe 27, so that the first water flow channel is connected to the water outlet 15 of the first water outlet pipe 22, and the second water flow channel is connected to the water outlet 15 of the second water outlet pipe 27; the first water outlet pipe 22 and the second water outlet pipe 27 are extended in a straight line and / or curved from the opening of the cavity of the water pressure chamber 2, and the extension directions of the first water outlet pipe 22 and the second water outlet pipe 27 are not colinear.

[0086] In detail, according to Bernoulli's principle, one of the basic principles of fluid mechanics, that is, when a fluid flows while ignoring viscosity losses, the sum of the pressure potential energy, kinetic energy and potential energy of any two points on the streamline remains unchanged. Therefore, in the water pressure chamber 2, due to the bending and contraction of the water flow channel, the flow direction of the water flow changes, and the flow velocity of the water flow is reduced, so that the kinetic energy of the water flow is converted into pressure potential energy, and then the water flow can rise to the opening 52, and a water pump is cocentrically arranged at the annular water inlet 26, so that the impeller of the water pump stirs the water flow to increase the kinetic energy of the water flow, and its rotational motion direction is consistent with the bending direction of the water flow channel, thereby reducing kinetic energy loss, that is, hydraulic loss.

[0087] Therefore, by making the first water outlet pipe 22 and the second water outlet pipe 27 non-collinear in their extension direction, the first baffle tongue 281 and the second baffle tongue 282 can be bent and extended to be inserted into the first water outlet pipe 22 and the second water outlet pipe 27, thereby reducing the kinetic energy loss of the water flow rotation motion.

[0088] Further, such as Figure 6 As shown, the included angle between the first water outlet pipe 22 and the second water outlet pipe 27 is an acute angle.

[0089] Specifically, Figure 3 and 6 As shown, two pairs of baffle tongues 28 bend and extend from the first connection portion 261 and the second connection portion 262 in opposite directions, a pair of baffle tongues 28 forming the second water flow channel are arranged in an annular shell 29 in an inverted S shape, and a pair of baffle tongues 28 forming the first water flow channel are arranged in an annular shell 29 in a hook shape, and the lower surfaces of the first water outlet pipe 22 and the second water outlet pipe 27 are recessed in the lower surface of the annular shell 29, so as to achieve that the water pressure chamber 2 is fixed to the inner surface or the inner tank of the drawer-type dishwasher. More specifically, the pair of baffle tongues 28 forming the second water flow channel bend and extend along the radial direction of the annular water inlet 26, are inserted into the second water outlet pipe 27, and after forming a bend in the opposite direction of its radial bend, are inserted into the water outlet 15 of the second water outlet pipe 27 in a straight line, and the pair of baffle tongues 28 forming the first water flow channel are inserted into the water outlet 15 of the second water outlet pipe 27 in a straight line in the first water outlet pipe 22.

[0090] Specifically, Figure 4 , 5 As shown in FIG. 6 , the first water outlet pipe 22 and the second water outlet pipe 27 are pipes with rectangular cross-sections, making it easier to connect and fix them to the structure in the dishwasher cavity, such as a tableware placement rack, thereby making the water pressure chamber 2 more stable.

[0091] Detailed, such as Figure 6 As shown, the amount of conversion of the kinetic energy of the water flow into pressure potential energy is related to the curvature and radius of the water flow channel. Therefore, the first water flow channel is bent from the front side of the annular water inlet 26 to the first water outlet pipe 22 on the front side of the annular water inlet 26, and its curvature and radius are smaller than those of the second water flow channel. Therefore, the contraction amplitude of the second water flow channel at the first connection portion 261 and the second connection portion 262 is greater than that of the first water flow channel, thereby increasing the curvature of the water flow channel. In addition, the second water flow channel is provided with a bend in the second water outlet pipe 27 opposite to its curvature direction near the annular water inlet 26, so as to supplement the position where the kinetic energy is converted into pressure potential energy, thereby ensuring that the water flow in the second water flow channel has sufficient pressure potential energy to rise to the opening 52.

[0092] In this embodiment, Figure 4 ,5 As shown in Figure 6, the water pressure chamber 2 also includes an annular shell 29; the annular water inlet 26 is arranged on the inner circumferential wall of the annular shell 29, the first baffle tongue 281 and the second baffle tongue 282 are arranged inside the annular shell 29, and the outer circumferential wall of the annular shell 29 is connected to the first water outlet pipe 22 and the second water outlet pipe 27.

[0093] An annular water inlet 26 is provided on the inner peripheral wall of the annular housing 29 so that it can be directly connected to a water pump or an impeller, thereby reducing hydraulic loss and ensuring that the water flow entering the water pressure chamber 2 has sufficient hydraulic force.

[0094] Specifically, Figure 4 , 5 As shown in FIG. 6 , an annular water inlet 26 is provided cocentrically with the annular shell 29 , and the annular water inlet 26 is provided with a snap-fit ​​structure that can be snap-fitted with the water outlet of the water pump, or the impeller or the water pump can be directly snapped into the annular water inlet 26 .

[0095] Specifically, Figure 3 and 5 As shown, the annular shell 29 is provided with reinforcing ribs 291 extending in the radial direction thereof, and a plurality of reinforcing ribs 291 are provided at intervals along the circumference of the annular shell 29, and are divided into three sections in the radial direction. Among them, three groups of the innermost reinforcing ribs 291 are provided at equal intervals along the circumference of the annular shell 29, so that the bottom of the annular shell 29 is connected by a snap connection with the surface of the inner tank of the drawer-type dishwasher, thereby fixing the water pressure chamber 2 and reducing the vibration caused by the impact of the water flow inside it.

[0096] In this embodiment, Figure 1 and 4 As shown, the drawer-type dishwasher further includes: a first connecting member 3 and a second connecting member 4; one end of the first connecting member 3 is connected to the water pressure chamber 2, and the other end is connected to the second connecting member 4; the second connecting member 4 is connected to the spray pipeline 1.

[0097] Through the first connecting piece 3 and the second connecting piece 4, the water flow of the water pressure chamber 2 is more directly sent to the spray pipeline 1, thereby reducing hydraulic loss.

[0098] Specifically, Figure 5 As shown, the portion where the water pressure chamber 2 and the first connecting member 3 are connected has a limiting groove 23, a rubber ring 24 and a limiting protrusion 25. The rubber ring 24 is clamped around the drain outlets of the first water outlet pipe 22 and the second water outlet pipe 27 to facilitate the disassembly of the water pressure chamber 2 and the first connecting member 3, and the connection has better sealing. The limiting protrusion 25 is arranged in the limiting groove 23 to make the connection between the water pressure chamber 2 and the first connecting member 3 more stable.

[0099] Specifically, Figure 7As shown, the first connecting member 3 extends horizontally, then extends obliquely upward, and then extends horizontally, so that it fits in the inner tank of the drawer-type dishwasher and is fixed with the tableware placement rack.

[0100] Specifically, Figure 3 and 4 As shown, the second connecting member 4 is vertically connected to the first connecting member 3. More specifically, the second connecting member 4 is vertically connected to the screw hole of the first connecting member 3 by a thread, and the spray pipeline 1 is inserted into the second connecting member 4, which facilitates the disassembly and replacement of the spray pipeline 1.

[0101] Furthermore, in this embodiment, the water spraying of the spray pipeline 1 can be controlled by controlling a water pump connected to the water pressure chamber 2 and / or providing a solenoid valve on the spray pipeline 1 .

[0102] Therefore, this embodiment realizes the upward transportation and three-dimensional spraying of the water output from the water pump through the spray pipe 1, and reduces the hydraulic loss in the process, so that the drawer-type dishwasher can perform three-dimensional spray cleaning from the opening 52 downward, avoiding dead corners in the spray cleaning of the drawer-type dishwasher, and achieving a better spray cleaning effect of the drawer-type dishwasher; through the setting method of the spray pipe 1, it occupies less space in the cavity of the drawer-type dishwasher; through the water pressure chamber 2, the water flow is pressurized to meet the needs of water flow pressurization for upward transportation and three-dimensional spraying of the drawer-type dishwasher.

[0103] Embodiment 2

[0104] like Figures 1 to 8 As shown, this embodiment provides a drawer-type dishwasher. The difference between this embodiment and the first embodiment is that the spray pipeline 1 includes:

[0105] The first pipeline 11 extends upward from the bottom of the cavity to a position close to the opening 52 of the cavity, then extends in a direction parallel to the second side of the opening 52, and then extends in a direction parallel to the third side of the opening 52;

[0106] The third pipeline 13 extends upward from the bottom of the cavity to a position close to the opening 52 of the cavity, then extends in a direction parallel to the fourth side of the opening 52, and then extends relatively in a direction parallel to the third side of the opening 52;

[0107] The second side of the opening 52 is parallel to the fourth side, and the third side is connected to the second side and the fourth side respectively;

[0108] The water outlet 15 is disposed at a portion of the first pipeline 11 extending along the second side and the third side, and at a portion of the second pipeline 12 extending along the third side and the fourth side.

[0109] Specifically, Figure 8As shown, the extended ends of the first pipe 11 and the third pipe 13 are spaced apart on the third side so that they can produce relative and uniform spray cleaning in the drawer-type dishwasher.

[0110] In detail, under the condition that the water flow and water pressure entering the spray pipe are sufficient, the first pipeline 11 and the third pipeline 13 are set to achieve uniform spray cleaning of the drawer-type dishwasher on three sides of the opening 52, thereby making the area for spray cleaning inside the drawer-type dishwasher larger.

[0111] In this embodiment, the third pipeline 13 extends to the opening 52 close to the cavity, then rounds by 90 degrees and extends horizontally to the intersection of the first side and the second side, fits the side wall of the cavity, and bends at the bend of the side wall;

[0112] The third pipeline 13 extends to the opening 52 close to the cavity, then bends 90 degrees with a rounded corner and extends horizontally to the intersection of the first side and the fourth side, bends 90 degrees again and extends in close contact with the side wall of the cavity.

[0113] By bending the rounded corners by 90 degrees and bending at the bend of the same side wall, the hydraulic loss of water flow is reduced, and the spray pipe 1 occupies less space in the cavity.

[0114] Embodiment 3

[0115] This embodiment provides a drawer-type dishwasher, which differs from the first embodiment in that the drawer-type dishwasher further comprises a mounting groove, which is arranged in the side wall of the inner tank of the drawer-type dishwasher, and the spray pipe 1 is at least partially installed inside the mounting groove. The mounting groove is used to replace the connecting device of the first embodiment, so that the spray pipe 1 has an installation mode of being arranged in the side wall of the inner tank of the drawer-type dishwasher.

[0116] Therefore, in this embodiment, the three-dimensional arrangement of the spray pipeline 1 does not occupy the cavity for placing tableware inwardly of the inner pot, so that the volume of the cavity is larger, and tableware can be placed more conveniently.

[0117] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
