[0054] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment of the present invention, a water receiving tray 2 is provided, comprising a shell 201, a pull-out assembly and a positioning assembly. The shell 201 is constructed to be movably arranged on the electrical device 1 along a first direction. The pull-out assembly is connected to the shell 201, and is used to drive the shell 201 to move between a first position and a second position along a first direction. The positioning assembly comprises a positioning portion 205 and a limiting portion 206, wherein the positioning portion 205 is fixedly arranged on the pull-out assembly, and the limiting portion 206 is fixedly arranged relative to the electrical device 1. When the shell 201 is located at the first position or the second position, the positioning portion 205 is matched with the limiting portion 206, and when the shell 201 is located between the first position and the second position, the positioning portion 205 is separated from the limiting portion 206.

[0055] The water receiving tray 2 is actually operated when the housing 201 is located at the first position, and the water receiving tray 2 is located inside the electrical device 1. At this time, the water receiving tray 2 can be used to store condensed water dropped from the evaporator 11 of the electrical device 1; when the housing 201 is located at the second position, the water receiving tray 2 extends out of the electrical device 1, and the water receiving tray 2 can be cleaned and disinfected. When an external pulling force acts on the pull-out assembly, the pull-out assembly can drive the housing 201 to move from the first position to the second position along the first direction to open the water receiving tray 2; when an external pressure acts on the pull-out assembly, the pull-out assembly can drive the housing 201 to move from the second position to the first position along the first direction to close the water receiving tray 2. At the same time, when the pull-out assembly moves, the positioning portion 205 is separated from the limiting portion 206 and moves with the pull-out assembly. When the pull-out assembly drives the housing 201 to move to the first position or the second position, the positioning portion 205 can be matched with the limiting portion 206 to fix the housing 201 at the first position or the second position.

[0056] In this way, when it is necessary to clean the water receiving tray 2, a pulling force is applied to the pull-out assembly to extend the housing 201 out of the electrical device 1, and the housing 201 is fixed in the second position by the cooperation of the positioning portion 205 and the limiting portion 206 so that the housing 201 remains stable. At this time, the housing 201 of the water receiving tray 2 can be cleaned without removing the housing 201 of the water receiving tray 2; when the cleaning is completed, pressure is applied to the pull-out assembly to push the housing 201 into the electrical device 1, and the housing 201 is fixed in the first position by the cooperation of the positioning portion 205 and the limiting portion 206 to achieve fixed installation of the water receiving tray 2. Compared with the existing ones, the water receiving box is easy to extract, and there is no need to repeatedly disassemble and assemble the water receiving box, which saves time and effort and greatly improves the cleaning efficiency. At the same time, through the optional matching of the positioning portion and the limiting portion, the cumbersome matching and disassembly of the screws is eliminated to achieve a screw-free operation, and the problem of screw stripping is also avoided.

[0057] It should be noted that the positioning portion 205 and the limiting portion 206 can be selectively matched. When the pull-out assembly drives the shell 201 to move, the positioning portion 205 and the limiting portion 206 are separated. When the shell 201 is in the first position or the second position, the positioning portion 205 and the limiting portion 206 are matched.

[0058] In some embodiments, see Figure 3 The pull-out assembly includes a pull-out rod 202. The housing 201 has an outer end face and an inner end face opposite to each other along a first direction, and the pull-out rod 202 has a first end and a second end opposite to each other along the first direction. The first end of the pull-out rod 202 is rotatably connected to the outer end face of the housing 201, and the second end of the pull-out rod 202 extends toward the inner end face of the housing 201; the positioning portion 205 is fixedly disposed on the pull-out rod 202.

[0059] It can be understood that the drawer rod 202 also moves along the first direction.

[0060] During actual operation, when a pulling force is applied to the pull-out rod 202 to pull the pull-out rod 202 outward, the shell 201 is driven to extend out of the electrical device 1 along the first direction, and the positioning portion 205 is separated from the limiting portion 206; when the shell 201 is in the second position, the positioning portion 205 is matched with the limiting portion 206, so that the shell 201 stops stably in the second position for cleaning and disinfection.

[0061] Specifically in the embodiment, the pull rod 202 is rotatably connected to the housing 201, and when the pull rod 202 rotates, it can drive the positioning portion 205 to rotate to the first hovering angle and the second hovering angle. When the pull rod 202 rotates to the first hovering angle, the positioning portion 205 and the limiting portion 206 are misaligned in the first direction; when the pull rod 202 rotates to the second hovering angle, the positioning portion 205 and the limiting portion 206 are opposite to each other in the first direction.

[0062] In actual operation, the pull rod 202 is rotated to drive the positioning part 205 to rotate to the first suspension angle, and the positioning part 205 is misaligned with the limiting part 206. At this time, when the positioning part 205 moves with the pull rod 202, the positioning part 205 will not interfere with the limiting part 206; when the pull rod 202 is rotated to drive the positioning part 205 to rotate to the second suspension angle, the positioning part 205 is opposite to the limiting part 206, so that when the housing 201 is at the first position or the second position, the positioning part 205 and the limiting part 206 can be matched. In this way, it is only necessary to rotate the pull rod 202 to switch the connection state between the positioning part 205 and the limiting part 206, and its structure is simple and easy to operate.

[0063] In practical applications, the first hovering angle may be a position where the positioning portion 205 is arranged horizontally, and the second hovering angle may be a position where the positioning portion 205 is arranged vertically.

[0064] Specifically in the embodiment, see Figure 2 , Figure 3 and Figure 4 In order to enable the pull-out rod 202 to drive the positioning portion 205 to hover at the first hovering angle and the second hovering angle, the pull-out assembly also includes a knob 203 and at least two positioning pins 204. The knob 203 is fixed to the first end of the pull-out rod 202 and is rotatably connected to the outer end surface of the shell 201. The at least two positioning pins 204 are matched with the outer end surface of the shell 201 and are arranged around the knob 203; the at least two positioning pins 204 are used to limit the knob 203 to rotate between the first hovering angle and the second hovering angle.

[0065] During actual operation, when the knob 203 is rotated, the pull-out rod 202 rotates accordingly. When the knob 203 is rotated to the first hovering angle, the positioning portion 205 on the pull-out rod 202 is separated from the limiting portion 206. When the knob 203 is rotated to the second hovering angle, the positioning portion 205 on the pull-out rod 202 is opposite to the limiting portion 206 in the first direction.

[0066] Further, see Figure 4 The number of the positioning pins 204 is four, and the four positioning pins 204 include two first positioning pins 204 arranged in parallel along the first angle direction, and two second positioning pins 204 arranged in parallel along the second angle direction; two opposite positioning rods are protruded in the vertical plane along the upper edge of the knob 203, and the positioning rods are detachably connected to the positioning pins 204; when the knob 203 is rotated, the positioning rod on the knob 203 can rotate between the adjacent first positioning pins 204 and the second positioning pins 204, and when the two positioning rods are respectively connected to the two first positioning pins 204, the knob 203 hovers at the first hovering angle; when the two positioning rods are respectively connected to the two second positioning pins 204, the knob 203 hovers at the second hovering angle.

[0067] In this way, the knob 203 is suspended by the cooperation of the four positioning pins 204 and the two positioning rods, thereby achieving the suspension of the positioning portion 205. The structure is simple and the operation is convenient.

[0068] Further, see Figure 4 A connecting hole is passed through the positioning rod, and a connecting column 204-1 is protruded from the positioning pin 204. The connecting column 204-1 of the first positioning pin 204 and the connecting column 204-1 of the second positioning pin 204 adjacent to each positioning rod both protrude toward the positioning rod. When the knob 203 is rotated to the first hovering angle, the connecting column 204-1 on the first positioning pin 204 is inserted into the connecting hole. When the knob 203 is rotated to the second hovering angle, the connecting column 204-1 on the second positioning pin 204 is inserted into the connecting hole, so as to realize stable and reliable hovering of the knob 203.

[0069] Specifically in the embodiment, see Figure 3 There are two positioning parts 205, and the two positioning parts 205 are arranged on the pulling rod 202 along the first direction; the limiting part 206 has a first side and a second side relative to each other along the first direction, the first side of the limiting part 206 is close to the inner end surface of the shell 201, and the second side of the limiting part 206 is far away from the inner end surface of the shell 201; when the shell 201 is in the first position, the positioning part 205 close to the outer end surface of the shell 201 abuts against the first side of the limiting part 206; when the shell 201 is in the second position, the positioning part 205 close to the inner end surface of the shell 201 abuts against the second side of the limiting part 206.

[0070] In actual operation, when the housing 201 needs to be moved, the pull rod 202 is rotated to drive the positioning portion 205 to hover to the first hovering angle. When the shell 201 moves to the first position, the pull-out rod 202 is rotated to drive the positioning portion 205 to hover to the second hovering angle. At this time, the positioning portion 205 located near the outer end surface of the shell 201 abuts against the first side of the limiting portion 206, that is, the two positioning portions 205 are both located on the first side of the limiting portion 206, so that the limiting portion 206 can provide the positioning portion 205 located near the outer end surface of the shell 201 with a force to overcome the movement tendency of the shell 201 to separate from the electrical device 1, thereby ensuring that the shell 201 is located inside the electrical device 1; when the shell 201 moves to the second position, the pull-out rod 202 is rotated to drive the positioning portion 205 to hover to the second hovering angle. At this time, the positioning portion 205 located near the inner end surface of the shell 201 abuts against the second side of the limiting portion 206, that is, the two positioning portions 205 are both located on the second side of the limiting portion 206, and the shell 201 extends out of the electrical device 1.

[0071] Furthermore, participate Figure 2 and Figure 3 The positioning assembly also includes an elastic member 207, one end of the elastic member 207 being fixed to the shell 201 at two opposite ends along the first direction, and the other end being constructed to be fixedly arranged relative to the electrical device 1; when the shell 201 is located at the first position or the second position, the elastic member 207 is used to provide a pre-tightening force to the positioning portion 205 to abut against the limiting portion 206.

[0072] During actual operation, when the shell 201 moves to the second position, the positioning portion 205 close to the inner end surface of the shell 201 abuts against the second side of the limiting portion 206, and the elastic member 207 is stretched between the electrical device 1 and the shell 201. The elastic member 207 provides a pre-tightening force close to the electrical device 1 to the shell 201. When this pre-tightening force indirectly acts on the positioning portion 205 abutting against the limiting portion 206, the positioning portion 205 is pressed against the limiting portion 206. At this time, the pre-tightening force provided by the elastic member 207 is opposite to the force of the limiting portion 206 acting on the positioning portion 205. In this way, the shell 201 can be in a balanced state when in the second position. At this time, the water receiving tray 2 can be cleaned without removing the water receiving tray 2.

[0073] In addition, when the shell 201 moves to the first position, the positioning portion 205 close to the outer end surface of the shell 201 abuts against the first side of the limiting portion 206, and the elastic member 207 is compressed between the electrical device 1 and the shell 201. The elastic member 207 provides a pre-tightening force to the shell 201 away from the electrical device 1. When this pre-tightening force indirectly acts on the positioning portion 205 abutting against the limiting portion 206, the positioning portion 205 is pressed against the limiting portion 206. In this way, the installation stability of the shell 201 in the first position can be guaranteed; at the same time, when the positioning portion 205 is rotated to the first suspended position, the reaction force generated by the pressure on the elastic member 207 helps the shell 201 to escape from the electrical device 1 along the first direction.

[0074] The elastic member 207 may be a spring, and optionally, one end of the spring is connected to the electrical device 1, and the other end of the spring is fixedly connected to the outer end surface of the housing 201. Alternatively, the water receiving box 2 further includes a fixing plate, one end of the spring is fixedly connected to the fixing plate, and the other end of the spring is fixedly connected to the outer end surface of the housing 201, and the fixing plate is used to be fixedly mounted on the electrical device 1.

[0075] It should be noted that in order to achieve that when the positioning portion 205 rotates to the second hovering angle and the shell is in the second position, the positioning portion 205 and the limiting portion 206 can be reliably abutted, this can be achieved by adding the above-mentioned elastic member 207, or by, for example: a positioning groove is provided on the positioning portion 205, and the limiting portion 206 can be snap-fitted into the abutting positioning groove.

[0076] Furthermore, the positioning portion 205 is a positioning hook, and the limiting portion 206 is a circular ring. The hook portion of the positioning hook can hook the circular ring, which helps the positioning portion 205 and the limiting portion 206 to be stably abutted.

[0077] The above embodiments are only preferred examples of the connection method between the positioning part 205 and the limiting part 206, and are not limitations on the connection method. In order to realize the optional matching between the positioning part 205 and the limiting part 206, there can be multiple ways of connecting the positioning part 205 and the limiting part 206. Optionally, there are two limiting parts 206, and the two limiting parts 206 are arranged at intervals along the first direction. Each limiting part 206 is provided with a conical hole, and the positioning part 205 is provided with one, and the positioning part 205 is located between the two limiting parts 206. The positioning part 205 is provided with a first convex cone protruding toward the first limiting part 206 and a second convex cone protruding toward the second limiting part 206, the first convex cone and the conical hole of the first limiting part 206 are gap matched, and the second convex cone and the conical hole of the second limiting part 206 are gap matched. When the housing 201 is located at the first position, the first convex cone of the positioning portion 205 is inserted into the tapered hole of the first limiting portion 206; when the housing 201 is located at the second position, the second convex cone of the positioning portion 205 is inserted into the tapered hole of the second limiting portion 206; when the housing 201 moves, the positioning portion 205 is separated from the limiting portion 206 under the action of an external force. At this time, the force when the positioning portion 205 is separated from the limiting portion 206 can be controlled according to the matching depth of the convex cone and the tapered hole.

[0078] In other embodiments, only one limiting portion 206 and one positioning portion 205 may be provided. For example, the limiting portion 206 is a limiting groove, and the two ends of the limiting groove have symmetrically arranged tapered holes. The positioning portion 205 can be slidably arranged in the limiting groove, and the tapered holes on the positioning portion 205 facing the two ends of the limiting groove are respectively provided with convex cones that match the gap of the tapered holes, and the convex cones can be inserted into or withdrawn from the tapered holes; when the housing 201 is located at the first position or the second position, one of the convex cones of the positioning portion 205 is matched and connected with the tapered hole of the corresponding limiting groove; when the housing 201 moves, under the action of external force, the convex cone of the positioning portion 205 is separated from the tapered hole of the limiting groove. At this time, the force when the positioning portion 205 is separated from the limiting portion 206 can also be controlled according to the matching depth of the convex cone and the tapered hole.

[0079] In addition, the pull-out assembly can be located on one or both of the two side surfaces of the housing 201 that are opposite to each other along a third direction that is perpendicular to the first direction, or can be located at the bottom of the housing 201. The first direction, the second direction, and the third direction are perpendicular to each other. Generally, the first direction and the third direction are arranged horizontally, and the second direction is arranged vertically.

[0080] In some embodiments, see 5, the water tray 2 further includes a bracket 208, the bracket 208 is used to be installed on the electrical device 1, and the housing 201 is movably disposed on the bracket 208 along the first direction. In actual application, the bracket 208 only needs to be fixedly installed on the electrical device 1.

[0081] Specifically in the embodiment, see Figure 5 and Figure 6 The water tray 2 further includes a guide rail assembly 209, which is fixed on the bracket 208, and the housing 201 is slidably connected to the guide rail assembly 209; the limiting portion 206 is fixed on the guide rail assembly 209. In this way, when the housing 201 is actually used, it slides along the guide rail assembly 209, which helps to ensure the straightness of the movement of the housing 201. At the same time, the limiting portion 206 is fixed on the guide rail assembly 209, and when the housing 201 moves to the first position or the second position, the positioning portion 205 on the pull rod 202 moves with the housing 201 to match the limiting portion 206.

[0082] Furthermore, the guide rail assembly 209 includes a guide bar 209-1, a limit plate 209-3 and a ball 209-2. The guide bar 209-1 extends longitudinally along the first direction and is fixed to the bracket 208, the limit plate 209-3 is fixed to the guide bar 209-1 and has a limit hole, and the limit portion 206 is fixed to the guide bar 209-1. The housing 201 and the guide bar 209-1 are sleeved, and the limit plate 209-3 is located between the housing and the guide bar. The ball 209-2 is limited to the limit hole and is rollingly matched with the housing 201 and the guide bar 209-1. In this way, when the housing 201 moves along the guide bar 209-1, the housing 201 is rollingly connected with the ball 209-2 on the guide bar 209-1, so that the moving friction of the housing 201 is converted into rolling friction through the ball 209-2, and the friction force is greatly reduced, which helps to improve the smoothness of the movement of the housing 201.

[0083] Furthermore, a groove 209-11 corresponding to the ball 209-2 is formed on one side of the guide bar 209-1 facing the limiting plate 209-3, and the parts of the ball 209-2 passing through the limiting hole at opposite ends respectively roll with the inner wall of the groove 209-11 and the housing 201. In this way, the ball 209-2 is limited by the groove 209-11 and the limiting hole, so that the ball 209-2 will not move during the rolling process and prevent the ball 209-2 from falling off, thereby improving the movement stability of the housing 201.

[0084] Preferably, the limiting portion 206 may be located at one end of the guide bar 209 - 1 close to the outer end surface of the shell 201 , so that the water collecting box can be pulled out of the electrical device 1 to the maximum extent, facilitating subsequent cleaning.

[0085] Further, see Figure 6The shell 201 is provided with a connecting frame 201-2 extending longitudinally along a first direction; the guide bar 209-1 has two sub-guide parts opposite to each other along a second direction perpendicular to the first direction, the limiting plate 209-3 has two sub-limiting parts opposite to each other along the second direction, and the connecting frame 201-2 has two sub-connecting parts opposite to each other along the second direction. One of the two sub-limiting parts is located between one of the two sub-guide parts and one of the two sub-connecting parts, and the other of the two sub-limiting parts is located between the other of the two sub-guide parts and the other of the two sub-connecting parts. The sub-guide part has a groove 209-11, and the sub-limiting part has a limiting hole. The ball 209-2 is limited in the limiting hole of the sub-limiting part and is rollingly matched with the sub-guide part and the sub-connecting part.

[0086] During actual operation, the connecting frame 201-2 of the shell is movably sleeved on two sub-guide parts, one of the sub-guide parts and one of the sub-limiting parts and the ball bearings thereon form a slide rail, and the other sub-guide part and the other sub-limiting part and the ball bearings thereon form another slide rail. The connecting frame 201-2 is slidably arranged on the two slide rails through the two sub-connecting parts. In this way, the stability of the moving process of the shell 201 can be greatly improved.

[0087] Furthermore, the length of the limiting plate 209 - 3 is smaller than the length of the guide bar 209 - 1 , and the limiting plate 209 - 3 is located at one end of the guide bar 209 - 1 close to the outer end surface of the shell 201 , which helps to reduce costs.

[0088] It can be understood that the housing 201 has a water containing chamber 201 - 1 and a water receiving port connected to the water containing chamber 201 - 1 to realize the water storage and water receiving function of the water receiving box.

[0089] In some embodiments, see Figure 7 , Figure 8 and Fig. 9 The water receiving tray 2 further includes a water baffle 210, which covers the water receiving port. The water baffle 210 includes a first water baffle 210-1 and a second water baffle 210-2, which are opposite to each other. A closed space is formed between the first water baffle 210-1 and the second water baffle 210-2. The first water baffle 210-1 has a first drain hole 210-11 connected to the closed space, and the second water baffle 210-2 has a second drain hole 210-21 connected to the closed space, and the second drain hole 210-21 is connected to the water receiving port. The orthographic projection of the first drain hole 210-11 on the second water baffle is located outside the range of the second drain hole 210-21.

[0090] Since the first water baffle 210-1 is far from the inner bottom wall of the housing 201, and the second water baffle 210-2 is close to the inner bottom wall of the housing 201, a height difference is formed between the first water-repellent hole 210-11 and the second water-repellent hole 210-21. At the same time, the first water-repellent hole 210-11 and the second water-repellent hole 210-21 are staggered in the second direction. When the fan of the electrical device 1 blows air at a high static pressure, the second baffle plate performs a first layer of shielding on the water vapor in the water tray 2. After part of the water vapor enters the closed space through the second water-repellent hole 210-21, it is blocked by the first water baffle 210-1 for a second layer. In this way, it can effectively prevent the water vapor in the water tray 2 from flowing back into the electrical device 1.

[0091] When the electrical equipment is in a high static pressure air supply state, the water receiving box provided in the embodiment of the present invention can prevent condensed water in the water receiving tray from being blown out due to high static pressure through the provision of the above-mentioned water baffle plate, thereby avoiding affecting the health and experience of users.

[0092] Furthermore, a first step surface 210-12 is protruding from the inner bottom wall of the first water baffle 210-1 facing away from the shell 201, and a second step surface 210-22 is protruding from the inner bottom wall of the second water baffle 210-2 facing the shell 201. The first step surface 210-12 is opposite to the second step surface 210-22, and the second drain hole 210-21 is located on the second step surface 210-22, and the first drain hole 210-11 is located at one end of the first water baffle 210-1 away from the first step surface 210-12.

[0093] In this way, the water vapor entering the closed space through the second drain hole 210-21 can be blocked by the first step surface 210-12 and the second step surface 210-22, and then converge along the first step surface 210-12 and the second step surface 210-22, and flow back into the shell 201 through the second drain hole 210-21. In this way, the water vapor in the water receiving tray 2 can be further prevented from flowing back into the electrical equipment 1.

[0094] The water receiving tray 2 provided in the embodiment of the present invention, when it is necessary to clean the water receiving tray 2, a pulling force is applied to the pull-out assembly to extend the housing 201 out of the electrical device 1, and the housing 201 is fixed in the second position by the cooperation of the positioning portion 205 and the limiting portion 206 so that the housing 201 remains stable, and at this time, the housing 201 of the water receiving tray 2 can be cleaned without removing the housing 201 of the water receiving tray 2; when the cleaning is completed, pressure is applied to the pull-out assembly to push the housing 201 into the electrical device 1, and the housing 201 is fixed in the first position by the cooperation of the positioning portion 205 and the limiting portion 206 to achieve the fixed installation of the water receiving tray 2. Compared with the prior art, the water receiving box is easy to extract, and there is no need to repeatedly disassemble and assemble the water receiving box, which greatly improves the cleaning efficiency; at the same time, the whole process does not require screw operation, which can avoid the problem of screw stripping.

[0095] In addition, an embodiment of the present invention further provides an electrical unit, including an electrical device and a water receiving tray 2 provided in any of the above embodiments arranged on the electrical device 1. Since the electrical unit includes the water receiving tray 2, it includes all the above beneficial effects, which are not described here.

[0096] It should be noted that the electrical device 1 includes a heat exchanger 11, and the water receiving tray 2 is located below the heat exchanger 11 and is used to receive and store condensed water generated by the heat exchanger 11. The heat exchanger may be an evaporator.

[0097] Among them, the electrical unit can be an air-conditioning unit, a refrigerator unit, a dehumidifier unit, etc., such as an air-conditioning unit for ground use in an aircraft.

[0098] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
