Detailed Description
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.
As shown in fig. 9, the heat pump cover plate 14 provided by the present invention includes a flat plate body 4, wherein a cover plate inclined portion 5 is formed on an inner side plate surface of the flat plate body 4, which is used for facing the heat pump bottom shell, and the cover plate inclined portion 5 is used for limiting a condenser arranged in a lower recess portion 6 formed by extending downward on the heat pump bottom shell.
Since the heat pump cover 14 includes the flat plate 4 and the cover inclined portion 5 is formed on the flat plate 4, after the heat pump cover 14 and the heat pump bottom case 13 are assembled with each other, the air duct 2 can be formed between the flat plate 4 and the heat pump bottom case 13, and the air duct 2 includes the flat portion 34 for disposing the evaporator and the lower recess 6 for disposing the condenser 9, which are horizontally arranged, so that the cover inclined portion 5 on the heat pump cover 14 can limit the condenser 9 disposed in the lower recess 6, so that the upper portions of the condenser 9 and the evaporator 33 are substantially in the same horizontal plane, which will significantly reduce the overall height dimension of the washing machine.
Of course, the cover plate inclined portion 5 may be formed on the flat plate body 4 in various forms, for example, in one form, the cover plate inclined portion 5 may be formed by welding or joining to an inclined plate directly on the surface of the flat plate body 4 facing the heat pump bottom case 13.
Alternatively, in another structure, as shown in fig. 9, the flat plate 4 and the cover inclined portion 5 are integrally formed, for example, the flat plate 4 is bent toward the heat pump bottom case to form the cover inclined portion 5, and then bent to extend away from the heat pump bottom case to form the clamping edge 8 for contacting and clamping with the heat pump bottom case, that is, the structure shown in fig. 9 is formed, so that the cover inclined portion 5 can be integrally formed on the flat plate 4 by punching or injection molding.
In addition, referring to the structures shown in fig. 1-5, 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 can be close to a filter screen arranged in the air duct after the heat pump cover plate 14 and the heat pump bottom shell 13 are assembled to form the air duct (as shown in fig. 1), so as to self-clean the filter screen arranged in the heat pump bottom shell 13 while water is entering; for example, the water that advances water structure spun can carry out the self-cleaning to the filter screen.
Like this, because be formed with inlet channel 15 on the heat pump apron 14, and inlet channel 15's the structure of intaking can be close to the filter screen setting, like this, in the in-service use, 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, in the plural rows of the spray holes, each row of the spray holes has a different spray position for more complete cleaning of the filter net, for example, in a structural form, as shown in fig. 2, the upper row of the spray holes is disposed close to the filter net mounting portion 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 so as to be able to wash down the filter net from the uppermost portion, and the lower row of the spray holes is disposed far from the filter net so as to be able to wash down the middle 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 the two straight passages 18 of the U-shaped passage are provided with water inlet structures, for example, a plurality of rows of spraying holes 17 are formed on the obliquely arranged passage walls 16 of the straight passages 18, 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, as shown in fig. 9, after the heat pump cover plate and the heat pump bottom shell are matched to form the air duct 2, a plurality of guide plates 30 extending along the air duct 2 are formed at a position of the air duct 2 close to the air suction opening 1, and the plurality of guide plates 30 divide the air duct section of the air duct 2 close to the air suction opening 1 into a plurality of air inlet ducts communicated with the air suction opening 1. Thus, the plurality of flow deflectors 30 and the plurality of air inlet ducts formed can rectify the air flow sucked into the air duct 2 from the air suction opening 1, so that the air flow is uniformly and stably distributed into the air duct 2 and uniformly passes through the evaporator 33, and the utilization rate of the evaporator 33 is greatly improved.
Of course, the plurality of baffles 30 may be arranged substantially parallel to the horizontal plane, that is, the plurality of baffles 30 are stacked at intervals in the height direction of the heat pump bottom case, thereby forming a plurality of air inlet ducts at intervals in the height direction.
Alternatively, in order to further enhance the rectifying effect of the air flow, it is preferable that the plate surfaces of the plurality of baffles 30 are arranged along the height direction of the heat pump bottom shell, as shown in fig. 9. Thus, in the width direction of the air duct 2, the plurality of guide plates 30 divide the air duct into a plurality of air inlet ducts arranged in the width direction, so that it is possible to ensure that the air flow sucked through the air suction opening 1 can pass through each air inlet duct at the first time.
In addition, as shown in fig. 9, a pipe connecting section 31 extending obliquely downward protrudes from the outside of the bottom shell of the heat pump at the air suction opening 1. Thus, the suction pipes 12 can be obliquely connected, so that the right-angle bending of the suction pipes 12 is avoided, and the air flow resistance and the space occupation of the suction pipes are reduced. Preferably, the air suction opening 1 is formed at the intersection of the bottom wall and the side wall of the bottom shell of the heat pump, so that the air suction opening can be maximally opened, the air volume is increased, and the air suction resistance is reduced.
In addition, in order to avoid the overall height of the washing machine from being too high, as shown in fig. 9, the heat pump bottom case may effectively use the upper space of the washing machine to arrange the condenser, and specifically, a portion of the heat pump bottom case 13 extends downward to form a bottom case inclined portion 27, and a portion of the heat pump cover 14 extends downward to form a cover inclined portion 5 corresponding to the bottom case inclined portion 27, wherein a lower recess 6 for disposing the condenser is provided between the bottom case inclined portion 27 and the cover inclined portion 5, and thus, the condenser 9 is fixed within the lower recess 6 by the bottom case inclined portion 27 and the cover inclined portion 5 in a limited manner to reduce the overall height of the washing machine.
In addition, on the basis of any one of the heat pump cover plates, the invention provides a washing machine which comprises a condenser and any one of the heat pump cover plates, wherein the condenser 9 is limited by the cover plate inclined part 5. Like this, heat pump apron and heat pump drain pan after assembling each other, can form the wind channel between straight plate body and heat pump drain pan, this wind channel then includes the straight portion and the lower depressed part that are used for setting up the evaporimeter that the level was arranged, and like this, the apron rake on the heat pump apron can carry on spacingly to the condenser that sets up in the depressed part down for the upper portion of condenser and evaporimeter is in same horizontal plane basically, and this will obviously reduce washing machine's whole height dimension.
Furthermore, the filter screen of the washing machine is installed on the filter screen installation part corresponding to the bottom case of the heat pump, for example, the first filter screen and the second filter screen are respectively installed on the filter screen installation parts corresponding to each other, and the water inlet structure is used for cleaning the filter screen arranged in the bottom case of the heat pump 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.
