Further, it should be noted that, in the description of the present invention, terms such as "inner", "outer", and the like, refer to directions or positional relationships based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the apparatus or components must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
Furthermore, it should be noted that, in the description of the present invention, unless explicitly specified and limited otherwise, the terms "connected," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be the communication between the two components. The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to the specific circumstances.
The washing device in the embodiment of the invention comprises washing devices with a drying function, such as a washing and drying integrated machine, a clothes dryer and the like. For convenience of description, the washing device is only taken as a heat pump washing and drying integrated machine for example, but this is not a limitation of the present invention, and those skilled in the art know that the washing device in the embodiment of the present invention may be a clothes dryer or other washing and drying integrated machine.
In the related art, a heat pump system in the washing and drying integrated machine comprises a shell, an evaporator, a condenser, a compressor and an expansion valve, wherein the compressor and the expansion valve are communicated with the evaporator and the condenser, both the condenser and the evaporator are arranged in the shell, an air inlet opposite to the evaporator and an air outlet opposite to the condenser are arranged on the shell, and the air inlet and the air outlet are communicated with an inside drying area of the washing and drying integrated machine. During operation, air enters through the air inlet, sequentially flows through the evaporator and the condenser, and then flows out through the air outlet, and as the air can be heated in the process of passing through the condenser, the air can dry clothes after flowing out through the air outlet. The shell is provided with an opening, the filter screen is inserted in the shell through the opening, and the filter screen is positioned between the evaporators of the air inlets so as to filter air flowing out of the air inlets.
At present, the drying principle of the heat pump washing and drying integrated machine is unknown for most users, so that the importance of the user on the filter screen in the heat pump system is not enough, the situation that the user cannot install the filter screen in place and the user can detach the filter screen at will easily in the use process of the heat pump washing and drying integrated machine, and even the situation that the filter screen is not installed can occur. In addition, the structure or the device for preventing the filter screen from being installed in place is not specially arranged for installing the filter screen in the related art, so that the probability of the filter screen not being installed in place is further increased. In addition, in the related art, a gap exists between the end part of the filter screen, facing the shell, and the shell, so that under the condition that the filter screen is not installed in place, the door body for sealing the opening can still be normally closed, and the filter screen is not installed in place and is not easy to find.
Therefore, the heat pump washing and drying integrated machine in the related art is easy to operate under the condition that the filter screen is not installed in place, so that air with impurities such as filings in the heat pump washing and drying integrated machine enters a heat pump system, and further the impurities such as the filings are adhered to the surface of a heat exchanger in the heat pump system, and the heat exchange efficiency of the heat exchanger is reduced.
In view of this, the embodiment of the invention provides a washing device, wherein a propping block is arranged on one side of a door body facing a filter screen, the propping block is propped against the filter screen after the door body is closed, and the filter screen is forced to move towards a preset position through the propping action, so that the washing device is installed in place. And under the condition that the filter screen can not be installed in place under the action of propping, the door body receives the reaction force of the propping acting force from the filter screen, so that the door body can not be normally closed, and a user can more easily find that the filter screen is not installed in place.
Hereinafter, a washing apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the washing apparatus provided by the embodiment of the present invention includes a housing 100, and a heat pump system and a working chamber provided in the housing 100.
The working cavity is a cavity for accommodating clothes to be dried. Taking washing equipment as an example of a washing and drying integrated machine, a cylindrical outer barrel with an axis in a horizontal direction is installed in a shell 100 of the washing equipment, an inner space formed by surrounding the outer barrel is a working cavity, a cylindrical inner barrel is coaxially arranged in the outer barrel, the inner barrel can rotate along the axis of the inner barrel, pick-and-place openings are formed in the same sides of the outer barrel and the inner barrel and are used for picking and placing clothes, and a door assembly is arranged on the shell 100, corresponding to the pick-and-place openings, in an openable and closable manner and is used for sealing the pick-and-place openings so that the working cavity is sealed. When the clothes are required to be dried, the door assembly is opened, the clothes to be dried are placed into the inner cylinder through the taking and placing opening, and then the door assembly is closed to start drying. Wherein, in the stoving in-process, the inner tube can drive and wait to dry clothing and rotate to shake and scatter and wait to dry clothing, improve the stoving effect.
Of course, the shape and the forming manner of the working chamber are not limited in the embodiment of the present invention. The working cavity can also be in other shapes such as a sphere, a polygon prism and the like; the working cavity can be formed by encircling the outer cylinder only, and the inner cylinder is not arranged inside the working cavity. In short, a cavity for accommodating laundry to be dried can be formed.
The heat pump system includes a housing 210 and a refrigerant circulation system 220. The housing 210 encloses an air inlet, an air outlet, and an air duct communicating the air inlet and the air outlet, both of which are communicated with the working chamber. The refrigerant circulation system 220 includes an evaporator and a condenser, and a compressor, a refrigerant pipe, and an expansion valve that connect the evaporator and the condenser in series into one refrigerant circulation circuit. The evaporator and the condenser are both arranged in the air duct, the evaporator is arranged close to the air inlet, and the condenser is arranged close to the air outlet. During drying, high-humidity air in the working cavity enters the air duct through the air inlet to exchange heat with the evaporator, the temperature of the high-humidity air is reduced after the heat of the high-humidity air is absorbed by the evaporator, moisture in the air is condensed and separated out on the evaporator, the high-humidity air becomes low-temperature drying air, the low-temperature drying air continuously flows towards the condenser along the air duct and exchanges heat with the condenser, the low-temperature drying air absorbs the heat of the condenser and becomes high-temperature drying air, and the high-temperature drying air is discharged into the working cavity through the air outlet to dry clothes to be dried.
The working principle of the refrigerant circulation system 220 may refer to existing refrigeration devices such as an air conditioner and a refrigerator, and will not be described herein.
The heat pump system further comprises a filter screen 230, wherein the filter screen 230 stretches into the air duct and is used for filtering impurities such as filings in air in the air duct, and the impurities are prevented from adhering to the surface of the heat exchanger to influence heat exchange efficiency. Optionally, a filter screen 230 is provided between the air intake and the evaporator. Air entering from the air inlet is filtered by the filter screen 230 and then exchanges heat with the evaporator and the condenser, so that impurities such as filth and the like are prevented from adhering to the evaporator, the condenser and the inner wall of the air duct between the evaporator and the condenser.
Of course, the location of the filter 230 is not limited thereto, and the filter 230 may be disposed at the air inlet. In addition, the filter screen 230 may be disposed between the evaporator and the condenser, for example, the evaporator is disposed near the air inlet, so that the air entering the condenser can be filtered, and the filter screen 230 is disposed between the evaporator and the condenser, so that the air entering the condenser can be filtered.
Optionally, a plugging channel extending into the air duct is provided on a side wall of the housing 210, and the filter screen 230 is plugged into the plugging channel. Illustratively, the housing 210 is provided with a socket penetrating through a sidewall of the housing 210, a limiting groove is provided on an inner wall of the housing 210 opposite to the socket, a socket channel is formed between the socket and the limiting groove, and one end of the filter screen 230 is inserted into the housing 210 through the socket and is embedded into the limiting groove to limit displacement of the filter screen 230. The filter screen 230 is fixedly arranged on the shell 210 relative to the filter screen 230, and the filter screen 230 is inserted in the insertion channel, so that the filter screen 230 can be detached from the shell 210, and the filter screen 230 is convenient to clean.
Of course, the installation mode of the filter 230 is not limited in the embodiment of the present invention. For example, the insertion openings may penetrate through the side walls of the opposite sides of the housing 210, and after the filter 230 is inserted into the housing 210, both ends of the filter 230 protrude out of the housing 210 through the insertion openings.
The housing 100 is provided with a window facing the plugging channel. Illustratively, the window is a circular opening open in the housing 100. In this way, the filter 230 may be removed from the washing apparatus through the window, and then washed.
Of course, the shape of the window is not limited in the embodiment of the present invention, for example, the window may be a rectangular opening, a polygonal opening, or the like.
The casing 100 is provided with a door body 110 capable of opening and closing, and the door body 110 is used for plugging a window. Illustratively, the door 110 is hinged to the housing 100 to be rotatable about a hinge point, and the window is closed and opened by rotation of the door 110 about the hinge point. For example, the door body 110 and the housing 100 are connected by a hinge, and the door body 110 is rotatable about an axis of the hinge.
Of course, the mounting manner of the door body 110 is not limited in the embodiment of the present invention, and the door body 110 may be slidably mounted on the housing 100. For example, a slide way is provided on the housing 100, and the door body 110 is slidably mounted on the slide way, so that the window can be plugged and opened by sliding the door body 110.
The door 110 is provided with a supporting block 111 towards one side of the plugging channel, and the supporting block 111 is supported on the filter screen 230. Illustratively, when the door 110 is hinged to the housing 100, a side of the abutment block 111 facing the filter 230 is provided with an abutment surface matching the shape of the end of the filter 230, and the abutment surface abuts against the filter 230 when the door 110 is closed. For example, the end of the filter 230 has a planar structure, and the abutment block 111 has a plate-like structure with one side thereof attached to the door 110, and the other side of the plate-like structure abuts against the filter 230.
Of course, the structure of the end of the filter 230 and the structure of the abutment block 111 are not limited in the embodiment of the present invention, as long as the abutment action of the abutment block 111 on the filter 230 when the door 110 is closed can be achieved. For example, the propping block 111 may be a columnar structure with a groove at the end, the end of the filter 230 is embedded into the groove when the door 110 is closed, the bottom of the groove is propped against the end of the filter 230, and the groove can also realize positioning of the filter 230.
In addition, when the door 110 is slidably mounted on the housing 100, the top surface of the supporting block 111 may be an inclined surface, so that the supporting block 111 is wedge-shaped as a whole, and the supporting effect of the supporting block 111 on the filter screen 230 is gradually enhanced along with the sliding of the door 110.
According to the washing equipment provided by the embodiment of the invention, the side wall of the shell 210 of the heat pump system is provided with the inwardly extending inserting channel, the filter screen 230 is inserted into the inserting channel, the shell 100 is provided with a window opposite to the inserting channel, the shell 100 is provided with the door body 110 which can be opened and closed, the door body 110 is used for plugging the window, one side of the door body 110 facing the inserting channel is provided with the propping block 111, and the propping block 111 is propped against the filter screen 230. Thus, when the door 110 is closed, the abutment block 111 on the door 110 abuts against the filter 230, and when the filter 230 is not mounted in place, the abutment action of the abutment block 111 can urge the filter 230 toward a predetermined position.
In addition, when the filter screen 230 is not yet installed in place under the abutting action, the filter screen 230 cannot completely close the door body 110 by the reaction force applied to the door body 110 by the abutting block 111, so that a user can more easily find that the filter screen 230 is not installed in place, and the washing device is prevented from running in a state that the filter screen 230 is not installed in place.
Alternatively, the abutment block 111 may be an elastic block. The elastic block can be integrally made of elastic materials and also can comprise an element with elasticity. For example, the elastic block may include a spring and a top abutment plate, one end of the spring is fixedly connected to the door body 110, the other end is fixedly connected to the top abutment plate, the top abutment plate abuts against the filter screen 230 when the door body 110 is closed, and compresses the spring, and the elastic force generated by compression of the spring is applied to the top abutment plate in turn, so that the top abutment plate abuts against the filter screen 230, and the filter screen 230 is installed in place. Thus, when the filter 230 is jammed, the elastic force of the elastic block can play a role of buffering, so that the filter 230 or the door 110 is prevented from being damaged due to the fact that the door 110 excessively extrudes the filter 230.
Of course, the elastic block can have other structures. For example, the elastic block is a V-shaped reed made of spring steel, one end of the V-shaped reed is fixedly connected to the door body 110, and the other end is used for abutting against the filter screen 230.
Further, the abutment block 111 is a rubber block. The rubber material has elasticity and good buffering effect.

When the door body 110 is closed, the main shaft 331 of the motor rotates to drive the locking arm 320 to swing along the main shaft 331, so that the other end of the locking arm 320 is embedded into the locking groove 310. Therefore, the motor can be controlled by controlling the power on-off state of the motor and the magnitude of the current and voltage values, and the control is more convenient.
Of course, the driving device 330 is not limited to a motor, but may be an electromagnetic relay, an action part of which is connected to the lock arm 320, and the action of the lock arm 320 is controlled by the energization or de-energization of the electromagnetic relay.
Further, the washing apparatus further includes a detecting apparatus and a control apparatus, wherein the control apparatus is electrically connected to the detecting apparatus and the locking device 300, respectively, and the control apparatus is used for controlling the locking device 300 to be connected to the door body 110 when the detecting apparatus detects that the filter screen 230 is in place. Thus, after the filter 230 is installed in place, the locking device 300 is connected with the door 110 to limit the rotation of the door 110, so that the propping block 111 keeps the propping action on the filter 230, and the filter 230 can be prevented from being separated from the original position under the influence of equipment vibration and the like. Moreover, by matching the control device and the detection device, the locking device 300 can be automatically controlled, so that the use of a user is more convenient. Illustratively, the control device may be a main control board mounted on the washing device, the main control board being the brain of the washing device for controlling the operation of the washing device, the main control board being used for controlling the operation of other components (e.g., a heat pump system) in the washing device in addition to the locking device 300. Of course, the control device may also be a control device provided independently of the main control board, and is used solely for controlling the motion of the locking device 300, and the form of the control device is not limited in the embodiment of the present invention.
Optionally, the detecting device includes a magnet and a reed pipe electrically connected to the control device, the reed pipe is disposed on the housing 210, and the magnet is disposed on the filter screen 230; alternatively, the reed switch is disposed on the filter 230 and the magnet is disposed on the housing 210. When filter screen 230 is in place, the magnet approaches the reed pipe to conduct the reed pipe, the control device detects the conduction signal number of the reed pipe, presumes that filter screen 230 is in place, and controls locking device 300 to lock door 110. Illustratively, the reed switch is disposed at the bottom of the mating channel, and the magnet is disposed at the end of the filter screen 230 and corresponds to the position of the reed switch, such that the magnet is within the conduction range of the reed switch when the filter screen 230 is in place. The magnet and reed switch technology is mature, the detection reliability is high, and the detection of the installation position of the filter screen 230 can be realized more stably.
Of course, the mounting positions of the magnet and the reed switch are not limited in the embodiment of the invention. The reed switch can also be arranged on the side wall of the plugging channel, and the magnet is arranged on the side surface of the filter screen 230 and corresponds to the position of the reed switch. In addition, the embodiment of the invention does not limit the composition of the detection device, the detection device can also comprise a travel switch, the travel switch is arranged at the bottom of the plugging channel, after the filter screen 230 is arranged in place, the filter screen 230 extrudes the travel switch to enable the travel switch to be conducted, and the detection of the installation position of the filter screen 230 can be realized.
Alternatively, the door body 110 is connected to the housing 100 through an elastic member 120, and the elastic member 120 is used to drive the door body 110 to rotate in the opening direction of the window. Thus, when the locking device 300 is not connected with the door 110, the door 110 automatically rotates under the action of the elastic member 120 to open the window, thereby facilitating the disassembly of the filter 230. In addition, the door body 110 does not need to be provided with a handle, so that the structure of the door body 110 is simpler.
Further, when the door body 110 is hinged on the housing 100, the elastic member 120 includes a torsion spring, the torsion spring is sleeved on the hinge shaft of the door body 110, the first driving end of the torsion spring abuts against the door body 110, and the second driving end of the torsion spring abuts against the housing 100.
