Description

Technical Field

[0001] The utility model relates to the technical field of dishwasher testing equipment, in particular to a door structure of a dishwasher used for experimental observation and the dishwasher. Background Art

[0002] A dishwasher is a kitchen appliance that can automatically wash dishes, plates, cups, pots and other tableware. Its appearance has greatly reduced the labor intensity after meals and improved the happiness of life. During the research and development and production process of dishwashers, it is necessary to test the performance parameters of dishwashers. The performance parameters of existing dishwashers are judged according to GB / T20290-2016. After the dishwasher and the standard machine have finished the program, the performance parameters are mostly tested by the test personnel with the naked eye according to the standard.

[0003] However, the doors of finished dishwashers sold are opaque. If the test personnel use such finished dishwashers directly for experimental observation, they cannot see the cleaning conditions inside the dishwasher. In addition, during the experiment, some operations are usually required to debug the performance parameters of the dishwasher. The doors of current front-opening dishwashers are usually opened or closed by flipping back and forth. This way of opening and closing the door is not convenient for operation during the experiment.

[0004] Therefore, it is necessary to design a dishwasher for experimental observation. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a door structure of a dishwasher for experiments which is convenient for operation during the experiment, in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a dishwasher for experiments using the above-mentioned door structure in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a door structure of a dishwasher used for experiments, characterized in that the door structure is used to open or close the front opening of the cabinet of the dishwasher, and the door structure includes two door panels arranged side by side in the left and right directions, the two door panels can move away from each other to open the opening of the cabinet, and the two door panels can move toward each other to cover the opening of the cabinet;

[0008] The door body structure also includes a driving mechanism, which is drivingly connected to the two door panels.

[0009] In order to position and install the driving structure so that the positioning structure and the door panel can be well matched, the door structure also includes a mounting frame for being installed on the box body, and the driving mechanism is installed on the mounting frame.

[0010] The driving mechanism can have a variety of structural forms, such as a motor with dual output shafts, the two output shafts corresponding to driving a door panel respectively, or the driving mechanism includes a motor, a belt and a pulley, the pulleys are at least two and are arranged at intervals in the left and right directions, each of the pulleys is installed on the mounting frame and can rotate around an axis extending in the front-back direction, the belt is sleeved on the pulleys, the motor is connected to at least one of the pulleys, one of the door panels is fixedly connected to the upper rib of the belt through a first connecting rod, and the other door panel is fixedly connected to the lower rib of the belt through a second connecting rod. Such a set of driving mechanisms drives two door panels at the same time, when the motor rotates in one direction, the two door panels move away from each other; when the motor rotates in the opposite direction, the two door panels move toward each other.

[0011] In order to limit the movement of the door panel, the mounting frame is provided with a first limit column and a second limit column spaced apart in the left and right directions. When the first connecting rod and the first limit column are abutted, and the second connecting rod and the second limit column are abutted, the door panel opens the opening of the box.

[0012] In order to guide the moving track of the door panels, the mounting frame is provided with a guide rod extending in the left-right direction, the first connecting rod and the second connecting rod are both provided with a guide groove, the guide rod is inserted in the guide groove, and the first connecting rod and the second connecting rod can move along the guide rod. The guide rod and the guide groove cooperate to guide the moving track of the two door panels.

[0013] In order to facilitate observation of the cleaning situation in the box and facilitate subsequent timing design, a local area of ​​at least one of the two door panels is a transparent structure.

[0014] In order to facilitate making the door panel partially transparent, the two door panels each include a frame with a hollow area, and the transparent structure is a transparent glass plate, and the transparent glass plate is embedded in the hollow area.

[0015] In order to improve the sealing performance when the door structure closes the opening of the box, sealing strips are provided on the walls of the two door panels facing each other. When the door structure covers the opening of the box, the sealing strips on the two door panels abut against each other.

[0016] The technical solution adopted by the utility model to solve the above second technical problem is: a dishwasher used for experiments, characterized in that it includes a box body and the above door body structure, the front side of the box body is open, and the door panel is arranged at the open part of the box body.

[0017] Compared with the prior art, the advantages of the utility model are as follows: in the early experimental process of the dishwasher, it is mainly the verification process of the cleaning test. When observing the cleaning, engineers need to match the design of the filter plate (for example, the water flow rate of the filter plate), the design of the slag basket (the size of the slag basket), the water column of the spray arm (whether it can be flushed into the corresponding tableware and the head and the flow rate of the spray hole), the rotation speed of the spray arm (the rotation speed also affects the cleaning performance), the stable liquid level of the water (too much or too little is not conducive to the stability of the cleaning performance), etc. In this process, the front and rear deflection door opening method of the dishwasher on the market is not convenient for arranging test tools (such as the access to the pressure gauge and the access to the flow meter) during the cleaning process, while the left and right opening and closing door body makes it convenient for engineers to put test tools such as pressure gauges and flow meters into the dishwasher to read the corresponding parameters.

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5 As shown, the dishwasher used for the experiment in this preferred embodiment includes a cabinet 1 and a door structure, the front side of the cabinet 1 is open, the door structure is used to open or close the opening 11 of the front side of the cabinet 1, and the door structure includes two door panels 2 arranged side by side in the left-right direction, the door panels 2 are arranged at the opening 11 of the cabinet 1, and the two door panels 2 can move away from each other to open the opening 11 of the cabinet 1, and the two door panels 2 can move toward each other to cover the opening 11 of the cabinet 1. The door structure also includes a driving mechanism 3 connected to the two door panels 2 to drive the two door panels 2 to move toward or away from each other.

[0025] A mounting frame 4 is installed on the top of the box body 1, and the driving mechanism 3 is installed on the mounting frame 4. The driving mechanism 3 includes a motor 31, a belt 32 and a pulley 33. There are at least two pulleys 33 and they are spaced apart in the left-right direction. Each pulley 33 is installed on the mounting frame 4 and can rotate around an axis extending in the front-back direction. The belt 32 is sleeved on the pulley 33. The motor 31 is connected to at least one of the pulleys 33 by driving. One of the door panels 2 is fixedly connected to the upper rib 321 of the belt 32 through the first connecting rod 21, and the other door panel 2 is fixedly connected to the lower rib 322 of the belt 32 through the second connecting rod 22. In this way, a set of driving mechanisms 3 drives two door panels 2 at the same time. When the motor 31 rotates in one direction, the two door panels 2 move away from each other; when the motor 31 rotates in the opposite direction, the two door panels 2 move toward each other.

[0026] In order to limit the moving range of the door panel 2, a first limit column 41 and a second limit column 42 are provided on the mounting frame 4 at intervals along the left and right directions. When the first connecting rod 21 and the first limit column 41 are abutted against each other, and the second connecting rod 22 and the second limit column 42 are abutted against each other, the door panel 2 opens the opening 11 of the box body 1. At this time, the door panel 2 cannot continue to move away from each other.

[0027] The walls of the frames 25 of the two door panels 2 facing each other are both provided with sealing strips 23. When the door structure covers the opening 11 of the box body 1, the sealing strips 23 on the two door panels 2 abut against each other to ensure the sealing performance when the door structure closes the opening 11 of the box body 1. At the same time, the two sealing strips 23 abut against each other, and the two door panels 2 cannot continue to move toward each other.

[0028] When the door panel 2 moves to the extreme position, the stall current of the motor 31 will increase. By judging the size of the stall current of the motor 31, it can be identified whether the door panel 2 is closed or open. This judgment process can adopt existing technology and will not be repeated here.

[0029] The mounting frame 4 is provided with a guide rod 43 extending in the left-right direction, and the first connecting rod 21 and the second connecting rod 22 are both provided with a guide groove 24, the guide rod 43 is inserted into the guide groove 24, and the first connecting rod 21 and the second connecting rod 22 can move along the guide rod 43. The guide rod 43 cooperates with the guide groove 24 to guide the moving track of the two door panels 2.

[0030] A partial area of ​​at least one of the two door panels 2 is a transparent structure, so as to facilitate observation of the cleaning situation in the box body 1 and facilitate subsequent timing design.

[0031] In this embodiment, the two door panels 2 both include a frame 25 , the frame 25 has a hollow area 26 , and the transparent structure is a transparent glass plate 5 , which is embedded in the hollow area 26 .
