The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Referring to the structures shown in fig. 1 to 5, the heat pump cover plate 14 provided by the present invention is formed with a water inlet channel 15, and the water inlet channel 15 is provided with a water inlet structure, which is capable of cleaning a filter screen disposed in the heat pump bottom shell 13 while water is supplied after the heat pump cover plate 14 and the heat pump bottom shell 13 are assembled (as shown in fig. 1); for example, the water inlet structure is close to the filter screen, so that water sprayed by the water inlet structure can automatically clean the filter screen.
In this technical scheme, because be formed with water inlet channel 15 on the heat pump apron 14, and water inlet channel 15's the structure of intaking can be close to the filter screen setting for example, like this, in the in-service use, water inlet structure spun hydroenergy can carry out the self-cleaning to the filter screen to washing machine when intaking, can make into to intake and carry out the self-cleaning to the filter screen, and this has guaranteed that the filter screen can obtain timely effectual clearance.
In the heat pump cover plate 14 of the present invention, the water inlet structure may have various structures, for example, in one structure, the water inlet structure may be a nozzle disposed in the air duct 2 and connected to the water inlet passage 15, so that the nozzle can clean the filter net.
Alternatively, in another structure, in order to simplify the structure and to make full use of the channel wall of the water inlet channel 15, it is preferable that the water inlet structure is a spray hole 17 formed on the channel wall 16 of the water inlet channel 15 facing the filter net, as shown in fig. 2 and 3. Thus, under the self pressure of tap water, water in the water inlet channel 15 is sprayed out from the spraying holes 17 to spray on the filter screen so as to self-clean the filter screen, and meanwhile, the arrangement of the spraying holes 17 can avoid that other spraying parts are arranged in the air duct 2 to influence the air suction area in the air duct 2.
Further, the number and arrangement of the spray holes 17 may be selected according to actual requirements, for example, as shown in fig. 1, 4 and 5, in the height direction of the water inlet channel 15, a plurality of rows of spray holes 17 are formed, and the number of each row of spray holes is plural. Thus, with multiple rows of spray holes, and multiple spray holes in each row, a more efficient self-cleaning of the filter screen from top to bottom is possible, as shown in fig. 2.
Further, in order to enable the rows of shower holes 17 to sufficiently clean the filter screen, it is preferable that the water inlet passage 15 be arranged obliquely toward the passage wall 16 of the filter screen, as shown in fig. 2 and 3. In this way, the spray water flow sprayed from each row of spray holes 17 will directly spray on the mesh surface of the filter mesh for more effective cleaning.
In addition, among the plural rows of spray holes, each row of spray holes has a different spray position for more complete cleaning of the filter net, for example, in one configuration, as shown in fig. 2, the upper row of spray holes is disposed close to the filter net mounting portions on the heat pump bottom case 13 such as the filter nets on the first filter net mounting portion 3 and the second filter net mounting portion 7 to wash the filter net from the uppermost portion downward, and the lower row of spray holes is disposed far from the filter net to wash the middle lower portion of the filter net. Therefore, the spraying positions of the multiple rows of spraying holes are different in point, and the filter screen is sprayed and cleaned more comprehensively.
Of course, this can be achieved by adjusting the size of the spray holes, or the inclination angle, for example, as shown in fig. 3, the angle between the lower side surface of the upper row of spray holes 17 and the horizontal plane is smaller than the angle between the lower side surface of the lower row of spray holes 17 and the horizontal plane. Thus, the spray water of the upper row of spray holes 17 is easier to clean from the upper part of the filter screen downwards, and the lower row of spray holes 17 is easier to clean the middle lower part of the filter screen by spraying.
In addition, the heat pump cover plate 14 may form the water inlet channel 15 in various forms, for example, in one structural form, a water inlet pipe may be fixedly disposed on an outer plate surface or an inner plate surface of the heat pump cover plate 14, and then the water inlet pipe is connected with a nozzle;
alternatively, as shown in fig. 4 and 5, the water inlet passage 15 is a U-shaped passage, and two straight passages 18 of the U-shaped passage are provided with water inlet structures, for example, a plurality of rows of shower holes 17 are formed on the passage walls 16 of the straight passages 18 arranged obliquely, so that the filter net can be more easily cleaned all over the straight passages 18. Further, as shown in fig. 2, 4 and 5, a water channel groove 20, for example, a U-shaped water channel, is formed on the outer plate surface 19 of the heat pump cover plate 14, and a water channel cover plate 21 is covered on the water channel groove 20 to form the water inlet channel 15.
Of course, as shown in fig. 5, the starting end of the water inlet channel 15 is formed with a water inlet, as shown in fig. 6 and 7, the end of the water inlet channel 15 is provided with a cleaning structure extending towards the starting end of the backflow groove 22 between the filter screens in the heat pump bottom shell to clean the corner of the starting end, so that the cleaning structure can clean the corner of the starting end of the backflow groove 22 in the heat pump bottom shell, such as between two filter screens, and prevent the flock from accumulating at the dead angle.
It should be understood that the washing structure has various forms, for example, one form, and a draft tube having a same direction of each corner is protruded from the water inlet passage 15, and a front end of the draft tube is washed diagonally.
Alternatively, as shown in fig. 6, 7 and 8, the cleaning structure is a shower post 24 having a shower passage 23, the shower post 24 being formed at the end of the water inlet passage 15, wherein the wall of the shower passage 23 is formed with an opening 25 toward the corner of the starting end. For example, as shown in fig. 8, two openings 25 are formed toward two corners.
Thus, when the washing machine is fed with water, the water flow washes the corner of the starting end of the reflux groove through the spraying column 24 and the clamping hole 25, and the washed washing water can flow back into the drum of the washing machine through the reflux channel on the bottom shell of the heat pump.
For example, as shown in fig. 2, a first filter mounting portion 3 is formed in the air duct 2 on the heat pump bottom case 13, wherein a backflow water inlet is formed on an air duct wall of the air duct 2 located on one side of the first filter mounting portion 3, a backflow water outlet is formed on an air duct wall of the air duct 2 located on the other side of the first filter mounting portion 3, and a backflow passage for communicating the backflow water inlet and the backflow water outlet is provided on the heat pump bottom case 13.
Thus, because the air duct walls of the air duct 2 located at the two sides of the first filter mounting portion 3 are respectively formed with a return water inlet and a return water outlet, and the return water inlet and the return water outlet are communicated through a return channel, in this way, the washing machine water inlet system, such as the multi-row spray holes 17 on the heat pump cover plate 14, can wash the first filter screen mounted on the first filter mounting portion 3, as shown in fig. 8, at this time, the washing water at one side of the first filter mounting portion (for example, seeps into one side of the first filter screen when washing the first filter screen, and/or washes the second filter screen) can flow back through the return water inlet, the return channel and the return water outlet, for example, flow back to the air suction opening 1, then enter into the drum through the air suction pipe connected between the air suction opening 1 and the washing machine drum, and the washing water at the other side of the first filter mounting, then enters the drum through the air suction pipe, thereby avoiding the concentration of the washing water at one side of the first filter screen mounting part 3.
It should be noted that the first filter mounting portion 3 is not limited to the one shown in fig. 2, and it should be understood that the first filter mounting portion 3 may be a plurality of first filters arranged at intervals along the air duct 2, so that a plurality of first filters, for example, two first filter mounting portions 3, may be arranged, so that two first filters may be mounted, so that the return water on one side of each first filter, for example, between two first filters, may flow to the return channel through the respective return water inlets.
Further, as shown in fig. 2, the air duct 2 is formed with a second filter mounting portion 7 arranged at a distance from the first filter mounting portion 3, wherein the return water inlet is located between the first filter mounting portion 3 and the second filter mounting portion 7. Like this, the water that washes to the second filter screen that sets up on second filter screen installation department 7 can be through backward flow water entry and backward flow passageway backward flow, and at this moment, second filter screen installation department 7 can be one for along the direction of induced drafting, the second filter screen is located the downstream side of the first filter screen of a first filter screen or a plurality of interval arrangements. In this way, the heat pump cover plate of the washing machine can simultaneously clean the multiple layers of filter screens while feeding water, or specially clean the multiple layers of filter screens simultaneously, and the washing water at the downstream side can flow to the backflow channel through the backflow inlet to backflow.
In addition, on the basis of any one of the heat pump cover plates, the invention provides a washing machine which comprises any one of the heat pump cover plates, wherein a filter screen of the washing machine is arranged on a filter screen installation part corresponding to a heat pump bottom shell, for example, a first filter screen and a second filter screen are respectively arranged on the corresponding filter screen installation parts, and the water inlet structure is used for cleaning the filter screen arranged in the heat pump bottom shell while water is fed.
Therefore, when water enters the washing machine, the water inlet structure of the heat pump cover plate can be used for automatically cleaning the filter screen, the filter screen does not need to be manually taken out of the machine for cleaning, namely, the filter screen can be automatically cleaned when water enters every time, the filter screen can be timely and effectively cleaned, the air quantity of drying external circulation is ensured, and the drying efficiency is improved.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, numerous simple modifications can be made to the technical solution of the invention, including combinations of the individual specific technical features in any suitable way.
