[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses an energy-saving air heat pump dishwasher.

[0035] Reference Figure 1 and Figure 2 The dishwasher includes a machine body, which includes a housing 1, a washing tray, a washing arm, a water pump, a heat pump system 2, a control panel 3, and components such as sensors. The structure of the machine body is not described in detail here. In order to reduce the difficulty of repairing the heat pump system 2, the dishwasher also includes a drawer box 4 and an elastic locking member 5.

[0036] The drawer box 4 is a square box-shaped structure, the top of the drawer box 4 is open, and it is slidably arranged in the shell 1; the back of the shell 1 is provided with a receiving cavity, which is open at the back of the shell 1, and the opening size and contour of the receiving cavity are adapted to the drawer box 4, and a slide rail is integrally connected to the side of the drawer box 4, and a slide groove for the slide rail to slide is provided on the inner wall of the shell 1, and the drawer box 4 can slide back and forth in the shell 1 under the cooperation of the slide groove and the slide rail. At this time, the heat pump system 2 is assembled inside the drawer box 4, and when it is repaired, the drawer box 4 can be pulled out of the shell 1 for repair, and the process is convenient and quick.

[0037] Reference Figure 3 The elastic locking member 5 is movably arranged on the outer shell 1. When the drawer box body 4 is covered in the outer shell 1, the elastic locking member 5 locks and fixes the drawer box body 4. Specifically, the elastic locking member 5 includes a knob shaft 51, a swing arm 52, a torsion spring 53 and a limit block 54. The knob shaft 51 includes a shaft body and a knob fixed at one end of the shaft body. The shaft body is rotatably mounted on the side wall of the outer shell 1, and the knob is located outside the outer shell 1. At the same time, an avoidance groove is recessed on the inner wall of the outer shell 1. One end of the swing arm 52 is fixedly connected to the knob shaft 51. By rotating the knob, the swing arm 52 can be rotated into the avoidance groove.

[0038] At the same time, the torsion spring 53 is sleeved on the knob shaft 51, and the two ends are connected to the shaft body and the housing 1 respectively. The torsion spring 53 provides torque for the knob shaft 51, thereby driving the swing arm 52 to swing toward the inside of the housing 1; and the limit block 54 is fixedly arranged on the inner wall of the housing 1. When the torsion spring 53 is in a natural state, the limit block 54 abuts against the swing arm 52, and the swing arm 52 extends into the housing 1. Based on this state, a slot 41 for the swing arm 52 to be movably engaged is recessed on the outer wall of the drawer box body 4. The torsion spring 53 provides a driving force for the swing arm 52 to remain in the slot 41, so that the elastic locking member 5 is always engaged in the slot 41 in the normal state, and the locking action is maintained. When the drawer box body 4 needs to be taken out, it is only necessary to twist the knob shaft 51, and the operation is quick.

[0039] Furthermore, in order to improve the convenience of installing the pull-out box body 4 into the shell 1, an avoidance slope 521 is opened on the side surface of the swing arm 52 facing the pull-out shell body, and the avoidance slope 521 is in sliding contact with the pull-out box body 4. When the pull-out box body 4 slides into the shell 1, the avoidance slope 521 pushes the swing arm 52 to swing into the avoidance groove, and then avoids the pull-out box body 4 until the pull-out box body 4 completely covers the shell 1. Under the resetting action of the torsion spring 53, the swing arm 52 is elastically connected to the card slot 41. The setting of the avoidance slope 521 is conducive to the quick locking of the pull-out box body 4 during installation.

[0040] Furthermore, when the drawer box 4 is installed with the heat pump system 2, it is not convenient to use because of its heavy structure and heavy feel when drawn. Figure 4 The dishwasher also includes an elastic member 6, which includes a plurality of springs and is fixedly installed on the inner wall of the outer shell 1 facing the opening. One end of the elastic member 6 abuts against one side of the pull-out box body 4. During the unlocking process, the elastic member 6 can automatically pop the pull-out box body 4 out of the outer shell 1, making it easier for maintenance personnel to pull the pull-out box body 4 and open it more quickly.

[0041] In actual application, the heat pump system 2 usually uses a compressor to liquefy or vaporize the refrigerant or snow seed. In this process, water vapor will be generated on the surface of the heat pump body. At the same time, the gap between the outer shell 1 and the pull-out box body 4 will also be easily invaded by external water vapor. An overly humid working environment can easily cause damage to the electronic components in the dishwasher.

[0042] Based on this, refer to Figure 4 On the one hand, a sealing strip 7 is fixedly installed on the pull-out box body 4. The sealing strips 7 are respectively arranged on both sides of the pull-out box body 4, and the sealing strips 7 are in contact with the outer shell 1. The sealing strip 7 can lift the outer shell 1 and the pull-out shell to reduce the possibility of external water vapor invading the inside of the dishwasher.

[0043] On the other hand, a layer of supporting net is fixedly installed at the bottom of the pull-out box body 4, thereby forming an overhead layer 8, and a water collecting cavity is formed under the overhead layer 8. The heat pump system 2 is arranged on the supporting net of the overhead layer 8. Condensed water can flow into the water collecting cavity through the supporting net to avoid soaking the electronic components.

[0044] In addition, the housing 1 is provided with an air inlet 9 and an air outlet 10, respectively. At the same time, the dishwasher further includes an air extraction element 12. In this embodiment, the air extraction element 12 can be selected as an exhaust fan. The air extraction element 12 is fixedly mounted on the housing 1 and covers the air outlet 10. At the same time, a drying filter 11 is installed at the air inlet 9 to filter the external humid air. The air extraction element 12 extracts the air in the housing 1 out of the housing 1. Under the action of the air extraction element 12, the air flow can be accelerated, and the humid air can be extracted to the outside of the housing 1, so that the inside of the housing 1 remains dry.

[0045] The implementation principle of an energy-saving air heat pump dishwasher in the embodiment of the present application is as follows: the pull-out box body 4 can be locked and unlocked by operating the elastic locking member 5. When the pull-out box body 4 is unlocked, the pull-out box body 4 is pulled out of the outer shell 1, and the heat pump system 2 can be inspected and maintained, and the process is convenient and quick.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
