Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless specifically defined otherwise.

Embodiments of the present invention: as shown in Figures 1-7, a water receiving tray assembly for refrigeration equipment is disclosed. The water receiving tray assembly can be used in refrigerators, freezers, wine cabinets and other refrigeration equipment. The water receiving tray The assembly is placed in the refrigerator and under the evaporator to bear the frost that falls from the evaporator after defrosting. In order to solve the frosting problem of the evaporator, a heating wire is provided on the evaporator in the prior art, and the heating wire is used to heat the evaporator during the defrosting process to remove the frost from the evaporator. However, if the frost falling in the water receiving tray has large pieces of ice, it will accumulate in the water receiving tray, and it is difficult to melt the accumulated large ice pieces, which may easily cause blockage of the drainage channel.

In order to solve the above problems, part of the heating wire for heating the evaporator is introduced into the sump of the water receiving pan, which can effectively accelerate the melting of ice accumulated in the sump of the water receiving pan. The heating wire introduced into the sump of the water storage pan is generally in a suspended state, and it is easy to cause the heating wire to move during the falling of large pieces of frost. If the heating wire touches the inner tank during the movement, it is easy to cause damage to the inner tank. In addition, Although the setting of the heating wire can effectively prevent the large pieces of frost accumulated in the sump from melting, it cannot prevent the accumulation of frost in the drain pipe of the drainage channel. However, in the prior art, the drain pipes of the drainage channel are mostly thin tube structures, and the thin tubes The configuration of the structure also increases the risk of blockage of the drainage channels.

In order to solve the above problems, the water receiving tray assembly for refrigeration equipment disclosed in the present application includes: a water receiving tray 1 and a heat conduction support 2 arranged on the water receiving tray 1, and the water receiving tray 1 includes a water collecting tank 10 The tray body 11 and the drainage channel 12 communicating with the sump 10; the heat conduction bracket 2 is arranged on the tray body 11 and has a positioning part 21 for positioning and supporting the heating wire, and part of the heat conduction bracket 2 is arranged on Inside the drainage channel 12.

The drainage channel 12 is a pipe provided on the tray body 11, and has a water inlet provided on the tray body 11, the tray water channel communicates with the sump 10 through the water inlet, and the heat conducting bracket 2 is used for The heating wire passing through the sump 10 is supported and fixed, and the heating wire is used for heating the frost accumulated in the sump 10 to accelerate the melting efficiency of the ice in the sump 10 .

The positioning of the heating wire on the positioning part 21 can effectively realize the fixing of the heating wire, which can avoid the shaking of the heating wire caused by the frost falling process, thereby reducing the risk of contact between the heating wire and the inner container, and preventing the inner container from Damage caused by contact with heating wires. At the same time, part of the heat conduction bracket 2 extends to the drainage channel 12. Since the material of the heat conduction support 2 is a material with good thermal conductivity, the heat conduction support 2 can transfer the heat energy generated by the heating wire into the drainage channel 12, thereby avoiding the heat conduction channel. The accumulation of frost in 12 is conducive to the melting of frost and reduces the ice blockage of frost in drainage channel 12. In addition, due to the existence of heat conducting bracket 2, it can also play a certain blocking effect on larger pieces of frost and avoid large The frost of block gathers in the drainage channel 12.

In a specific embodiment, the heating wire emits heat after it is energized and works. At this time, the evaporator feels the heat from the heating wire, and the frost attached to the outer surface of the evaporator begins to melt, and the water drops after the frost melts fall to the water receiving tray. In the sink 10 of 1, the outside of the refrigerator is discharged from the drainage channel 12. At the same time, some larger ice cubes become loose due to the connection with the evaporator after being heated. Under the action of gravity, part of the whole ice cubes will fall off. Under the action, the ice cubes will fall into the water collection tank 10, and slide down to the drainage channel 12 along the bottom of the water collection tank 10. At this time, because the heat-conducting bracket 2 stretches into the drainage channel 12, it will play a role in the large ice cubes. A certain blocking effect causes the large ice cubes to fail to enter the drainage channel 12 and get stuck between the drainage channel 12 and the heat conduction bracket 2. At the same time, due to the close contact between the ice cubes and the heating wire, the ice cubes will receive a lot of heat , and quickly melt into water, the melted water can smoothly enter the drain pipe from the drainage channel, and discharge out of the refrigerator. After the gap between 2 enters, due to the heat conduction effect of the heat conduction bracket 2, the heat is transferred to the drainage channel 12, which can quickly melt the frost entering the drainage channel 12, thereby avoiding the accumulation of large pieces of frost in the drainage channel 12 and causing ice blockage Case.

As shown in Figures 1-5, in this embodiment, the disc body 11 has a conical structure as a whole, and the water inlet of the drainage channel 12 is arranged at the lowest part of the conical structure. The arrangement of the above structure can facilitate the drainage of ice and frost Convergence of channels 12, the cross-section of the tray body 11 is approximately rectangular, therefore, the water receiving tray 1 has a length direction and a width direction, the length direction is the left-right direction, and the width direction is the front-rear direction. The specific shape of the tray body 11 is adapted to the shape of the evaporator. The cross section of the evaporator in the prior art is rectangular and extends along the left and right directions.

The conical structure of the disc body 11 is an asymmetrical conical structure, that is, the lowest point of the conical shape is not at the center of the disc body 11. In this embodiment, the lowest position of the conical shape is on the left side in the left-right direction. This causes the bottom of the tray body 11 to form two first slope bottom surfaces 111 and second slope bottom surfaces 112 with different slopes, wherein the slope of the first slope bottom surface 111 is greater than the slope of the second slope bottom surface 112 . The setting of the above-mentioned structure makes the flow velocity on both sides inconsistent when the water flow converges to the drainage channel 12, which can avoid the collision of the water flow on both sides at the inlet position of the drainage channel 12, resulting in poor drainage.

The heat conducting bracket 2 has a bracket body 22 connected and fixed to the positioning portion 21 and positioned in the drainage channel 12 . The bracket body 22 and the positioning portion 21 are integrally formed metal plates. In order to realize the installation and fixation of the heat conducting bracket 2 conveniently, a slot matching with the bracket body 22 is provided in the drainage channel 12 , and the bracket body is plugged and positioned in the slot.

As shown in FIGS. 6-8 , the positioning portion 21 is a metal plate extending parallel to the width direction of the water tray 1 , and several positioning grooves 210 are formed on the positioning portion 21 along the width direction. Since the heating wires in the prior art generally extend along the length direction of the disc body 11, and generally multiple heating wires are installed in the sump 10 at the same time, in order to better fix the heating wires, the There are multiple positioning parts 21 and they are arranged along the width direction of the water tray 1 .

In order to facilitate the manufacture of the heat-conducting bracket 2, correspondingly, the bracket body 22 is extended along a direction parallel to the extension of the positioning portion 21, that is, the bracket body 22 is extended along the width direction, and the bracket body 22 is extended along the width direction. The size of 22 is adapted to the size of drainage channel 12.

For better heat conduction and more stable support and fixation of the heating wire, two heat conduction brackets 2 are provided in each drainage channel 12, namely a first heat conduction bracket 23 and a second heat conduction bracket 24, The first heat conduction bracket 23 and the second heat conduction bracket 24 are symmetrically arranged in the drainage channel 12 . A water flow blocking area 25 is formed between the first heat conduction bracket 23 and the second heat conduction bracket 24 .

In the above embodiment, setting the bracket body 22 to extend along the width direction can facilitate the production and manufacture of the heat conducting bracket 2 , but it is not conducive to the convergence of the water flow to the drainage channel 12 . Because the disc body 11 has a length direction and a width direction, and the bottom of the disc body 11 forms a first slope bottom surface 111 and a second slope bottom surface 112 with different slopes in the length direction, since the first slope bottom surface 111 and the second slope bottom surface 112 are both It is arranged obliquely in the length direction, and the water flow will converge into the drainage channel 12 mainly along the first slope bottom surface 111 and the second slope bottom surface 112 . Due to the existence of the bracket body 22 in the water converging process, and the bracket body 22 is arranged along the width direction, it means that the bracket body 22 is perpendicular to the water flow direction, which causes the bracket body 22 to have a blocking effect on the water flow, and this blocking The effect is particularly remarkable for the scheme of setting two heat conducting brackets 2 in one drainage channel 12 . As shown in Figure 6 or 7, only a small amount of water flows through the water flow blocking area 25 between the first heat conducting bracket 23 and the second heat conducting bracket 24, and the first heat conducting bracket 23 and the second heat conducting bracket 24 form a blocking effect on the water flow , the water flowing in the length direction cannot directly flow to this area, but can only be bypassed from the side, which causes the reduction of the drainage channel, thereby affecting the discharge of the water flow. The area corresponding to the water flow blocking area 25 has no drainage effect, therefore, the setting of this structure actually reduces the size of the drainage section of the drainage channel 12, which will affect the unobstructed drainage.

In order to solve the above technical problems, the drainage channel 12 has a water inlet arranged at the bottom of the water receiving tray 1, and a perforation 220 penetrating through the bracket body is provided on the bracket body 22 opposite to the position of the water inlet. The height of the perforation 220 in the vertical direction is not lower than the height of the water inlet. There are multiple through holes 220, and the multiple through holes 200 are arranged at intervals along the width direction.

Perforations are set above the bracket body 22. When the bracket body 22 is extended perpendicular to the length direction, the water flow gathered in the length direction will not be blocked or affected. The water flow gathered in the length direction can enter between the two bracket bodies through the perforation. There is a gap between them, thereby avoiding the situation that the effective drainage size of the drainage channel 12 is severely reduced due to the insertion of the bracket body 22 into the drainage channel 12 .

In the above embodiment, the bracket body 22 is extended parallel to the width direction. In another embodiment, the bracket body 22 can also be configured as a metal plate extending parallel to the length direction of the water receiving tray 1 . The bracket body 22 is extended along the length direction parallel to the water tray 1 , and the bracket body 22 is perpendicular to the positioning portion 21 . The setting of the above structure will reduce the blocking effect of the bracket body 22 on the water flow in the length direction of the water tray 1, and the length direction is the main direction of water collection in the tray body 1, so the drainage of the drainage channel 12 can be reduced even less.

Another embodiment of the present invention also discloses a refrigeration device, which includes a box body, an inner container arranged on the box body, an evaporator arranged in the inner bag, a heating wire, and a water receiving device as described above. a pan assembly, the water receiving pan assembly is disposed on the lower side of the evaporator, the heating wire has a first section that provides heat for the evaporator and a second section that extends inside the water receiving pan, The second segment is positioned on the heat conducting bracket.

The structure, features and effects of the present invention have been described in detail above based on the embodiments shown in the drawings. The above descriptions are only preferred embodiments of the present invention, but the present invention does not limit the scope of implementation as shown in the drawings.
