[0002] Spray-type dishwashers need to undergo a comprehensive cleaning test before leaving the factory. The existing spray-type dishwasher comprehensive cleaning test method usually involves applying contaminants on the surface of tableware, then placing the tableware coated with contaminants according to the dishwasher's dish rack placement requirements and cleaning it. During the spray-cleaning process of the tableware, the spraying water flushes and cleans the contaminants on the surface of the tableware, and finally observes the amount of contaminants remaining on the surface of the tableware, and then uses the observed amount of contaminants remaining on the surface of the tableware as a test standard for the cleaning effect of the spray-type dishwasher.

[0003] However, the existing method for detecting the comprehensiveness of cleaning of the spray-type dishwasher has shortcomings: when users actually use the spray-type dishwasher, they do not place the dishes on the dishwasher rack completely according to the placement requirements. Once the tableware is not placed in accordance with the requirements, there will be cleaning dead corners in the spray chamber of the spray-type dishwasher, and it is impossible to perform a comprehensive detection of the cleaning effect of the spray-type dishwasher in the spray chamber, resulting in unclean cleaning of the dishes.

[0004] Therefore, the existing spray dishwasher cleaning comprehensiveness detection method is difficult to meet the actual situation of users' use of the spray dishwasher to clean dishes, and cannot reflect the spray dishwasher cleaning comprehensiveness detection situation more accurately and in accordance with actual usage.

BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 It is a schematic diagram of a cleaning comprehensiveness detection device for a spray-type dishwasher in an embodiment of the utility model. DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] This embodiment provides a cleaning comprehensiveness detection device for a spray-type dishwasher. Figure 1 As shown, the cleaning comprehensiveness detection device for a spray-type dishwasher of this embodiment includes a force-bearing panel 1, a driving mechanism, a pressure collection device 3 and a control terminal 4. The force-bearing panel 1 has an upper surface 1a that bears the impact of the spray water flow, and a plurality of pressure detection devices 11 are distributed on the upper surface 1a. The pressure detection device 11 is preferably a pressure-sensitive sensor element to convert the pressure data borne into an electrical signal; wherein, the force-bearing panel 1 is configured to be set in the spray cavity C of the spray-type dishwasher and can be driven to move up and down along the axial direction of the spray cavity C; the driving mechanism drives the force-bearing panel 1 to move up and down along the axial direction of the spray cavity C after being controlled; the pressure collection device 3 is respectively connected to each pressure detection device 11 on the force-bearing panel 1 to collect the impact pressure of the spray water flow borne on the upper surface of the force-bearing panel detected by each pressure detection device, and the control terminal 4 is respectively connected to the driving mechanism and the pressure collection device 3.

[0027] When it is necessary to perform a comprehensive cleaning test on the spray-type dishwasher, the control terminal controls the driving mechanism to operate so that the driving mechanism drives the force-bearing panel to move axially along the spray cavity to a height, and then the pressure detection devices on the upper surface of the force-bearing panel send the spray water flow impact pressures detected by each device to the pressure acquisition device, and then the pressure acquisition device sends these pressure data to the control terminal for processing, and the water flow impact force data of each specific position of the current height level position of the spray-type dishwasher in the spray cavity are obtained, and then the control terminal controls the driving mechanism to move the force-bearing panel to another height along the spray cavity, and then the water flow impact force data of each specific position of the height level position are obtained; the driving of the force-bearing panel is continuously executed in sequence, so as to finally obtain the water flow impact force data of each position of the spray-type dishwasher in the spray cavity, thereby achieving a comprehensive cleaning test effect on the spray-type dishwasher.

[0028] In order to make a more comprehensive detection of the water flow impact force borne by each position on the upper surface of the stress-bearing panel, in this embodiment, the above-mentioned plurality of pressure detection devices 11 are distributed throughout the upper surface 1a of the stress-bearing panel 1. For example, the plurality of pressure detection devices 11 here are preferably evenly distributed on the upper surface 1a of the stress-bearing panel 1.

[0029] As a specific implementation of the driving mechanism, the driving mechanism of this embodiment includes a support rod 21, a transmission rod 22 and a motor 23. The support rod 21 and the transmission rod 22 are both arranged in the spray cavity C. The motor 23 is connected to the transmission rod 22 and is connected to the control terminal 4. The first sleeve 12 and the second sleeve 13 are respectively arranged on the force-bearing panel 1. The support rod 21 passes through the corresponding first sleeve 12, and the transmission rod 22 passes through the corresponding second sleeve 13. In this way, the support rod passing through the first sleeve becomes a guide rail for the force-bearing panel to move up and down along the axial direction of the spray cavity. After the motor drives the transmission rod to move, the transmission rod can drive the force-bearing panel to move up and down along the axial direction of the spray cavity.

[0030] In order to enhance the stability of the force-bearing panel when it moves up and down in the spray cavity, in this embodiment, the driving mechanism has two support rods 21 and two transmission rods 22, and the two support rods 21 and the two transmission rods 22 are respectively and correspondingly arranged at the four corners in the spray cavity C. For example, the two support rods 21 are located on a diagonal line in the spray cavity C, and the two transmission rods 22 are located on another diagonal line in the spray cavity C.

[0031] In order to more accurately detect the spray cleaning conditions at various positions in the spray chamber, as a preferred embodiment, the transmission rod 22 of this embodiment is a screw rod, the second sleeve 13 is a threaded sleeve, and the motor 23 is a stepping motor.

[0032] In the actual detection process, in order to more intuitively understand or observe the cleaning situation of the spray-type dishwasher, the control terminal 4 of this embodiment has a display screen. Through the display screen, the water flow impact force borne by each point on each height level in the spray cavity can be displayed, thereby forming an effective cleaning area and a weak cleaning area showing the spray-type dishwasher's cleaning of the spray cavity. Among them, the effective cleaning area is formed by the points where the water flow impact force borne is greater than or equal to the preset impact force threshold; the weak cleaning area is formed by the points where the water flow impact force borne is less than the preset impact force threshold.

[0033] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention may be modified and varied by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
