The embodiment of the invention comprises the following steps: as shown in fig. 1-7, a water pan assembly for a refrigeration device is disclosed, which can be used for a refrigerator, a freezer, a wine cabinet and other refrigeration devices, and is placed in the refrigerator and positioned below an evaporator for bearing frost falling after defrosting of the evaporator. In order to solve the problem of frost formation of the evaporator, a heating wire is arranged on the evaporator in the prior art, and the heating wire is used for heating in the defrosting process so as to remove frost from the evaporator. However, if large ice blocks of frost falling into the water receiving tray accumulate in the water receiving tray, the accumulated large ice blocks are difficult to melt, and the water drainage channel is easily blocked.

In order to solve the problems, part of heating wires for heating the evaporator are introduced into the water collecting groove of the water receiving disc, so that the ice accumulated in the water collecting groove of the water receiving disc can be effectively and quickly melted. The heater strip of introducing ponding dish catchment inslot is generally in the suspended state, drop the removal that the in-process caused the heater strip easily at bold frost, the heater strip is at the removal in-process if contact the inner bag and make the damage to the inner bag easily, the setting of heater strip is in addition though can effectually avoid the bold frost that gathers in the catchment inslot to melt, but can not avoid the frost to gather in drainage channel's drain pipe, and drainage channel's drain pipe is mostly the tubule structure among the prior art, the setting of tubule structure has also aggravated the risk that drainage channel blockked up.

In order to solve the above-mentioned problem, the water collector subassembly for refrigeration plant that this application discloses includes: the water collecting tray comprises a water collecting tray 1 and a heat conduction support 2 arranged on the water collecting tray 1, wherein the water collecting tray 1 comprises a tray body 11 with a water collecting groove 10 and a drainage channel 12 communicated with the water collecting groove 10; the heat conductive bracket 2 is provided on the tray body 11 and has a positioning part 21 for positioning and supporting the heating wire, and a part of the heat conductive bracket 2 is provided in the drain passage 12.

The drainage channel 12 is a pipeline arranged on the tray body 11 and is provided with a water inlet arranged on the tray body 11, the tray water channel is communicated with the water collecting tank 10 through the water inlet, the heat conduction bracket 2 is used for supporting and fixing a heating wire penetrated from the water collecting tank 10, and the heating wire is used for heating the frost gathered in the water collecting tank 10 so as to accelerate the melting efficiency of the frost in the water collecting tank 10.

The heater strip location can be effectual fixed of realization heater strip on location portion 21, can avoid rocking of the heater strip that the in-process that drops at the frost leads to, and then reduced the risk of the contact of heater strip with the inner bag, make the inner bag avoid in the harm that causes with the heater strip contact. Simultaneously, this heat conduction support 2 part extends to drainage channel 12, the material of heat conduction support 2 is owing to be the material that has good heat conductivity, thereby heat energy transmission that heat conduction support 2 can produce the heater strip has avoided the gathering of the interior frost of heat conduction channel 12 in drainage channel 12, be favorable to melting of frost, the stifled condition of frost in drainage channel 12 has been reduced, in addition, because the existence of heat conduction support 2 also can play certain effect of blockking to great piece frost more and can avoid massive frost to assemble in drainage channel 12.

In a specific embodiment, heat is emitted after the heating wire is powered on, at this time, the evaporator senses the heat of the heating wire, frost attached to the outer surface of the evaporator begins to melt, water after the frost melts drops into the water collecting groove 10 of the water receiving tray 1, and is discharged out of the refrigerator from the water drainage channel 12, meanwhile, a plurality of large ice blocks become loose due to connection with the evaporator after being heated, under the action of gravity, a part of whole ice blocks drop off, the ice blocks fall into the water collecting groove 10 under the action of gravity, and slide to the water drainage channel 12 along the bottom of the water collecting groove 10, at this time, as the heat conduction bracket 2 extends into the water drainage channel 12, a certain blocking effect is achieved on the large ice blocks, the large ice blocks cannot enter the water drainage channel 12 and are stuck between the water drainage channel 12 and the heat conduction bracket 2, meanwhile, as the ice blocks are contacted with the heating wire closely, the ice blocks are melted, and are rapidly melted, and the water can be rapidly melted from the water drainage channel 12 to the water drainage channel 12, and the ice blocks can be prevented from entering the water drainage channel 12 after the ice blocks.

As shown in fig. 1 to 5, in this embodiment, the whole tray body 11 is a conical structure, the water inlet of the drainage channel 12 is disposed at the lowest portion of the conical structure, the above structure is convenient for the frost to gather into the drainage channel 12, and the cross section of the tray body 11 is substantially rectangular, so that the water receiving tray 1 has a length direction and a width direction, the length direction is a left-right direction, and the width direction is a front-back direction. The specific shape of the tray body 11 is adapted to the shape of the evaporator, which is a related art evaporator having a rectangular cross section and extending in the left-right direction.

The tray 11 has an asymmetric conical structure, that is, the lowest point of the cone is not located at the center of the tray 11, and in this embodiment, the lowest point of the cone is located at the left side in the left-right direction, so that the bottom of the tray 11 forms a first slope surface 111 and a second slope surface 112 with different slopes, wherein the slope of the first slope surface 111 is greater than the slope of the second slope surface 112. The arrangement of the structure ensures that the flow velocity of the water flow on the two sides is inconsistent when the water flow is converged to the drainage channel 12, and can avoid the unsmooth drainage caused by the opposite flushing of the water flow on the two sides at the inlet position of the drainage channel 12.

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

As shown in fig. 6 to 8, the positioning portion 21 is a metal plate extending in parallel to the width direction of the water collector 1, and a plurality of positioning grooves 210 are formed on the positioning portion 21 in the width direction. Since the heating wires in the prior art are generally extended along the length direction of the tray body 11, and a plurality of heating wires are generally simultaneously inserted into the water collecting tank 10, in order to fix the heating wires better, the positioning portion 21 is formed in plurality and arranged along the width direction of the water collector 1.

In order to facilitate the production of the heat conducting support 2, correspondingly, the support body 22 extends parallel to the extension direction of the positioning portion 21, that is, the support body 22 extends in the width direction, and the dimension of the support body 22 in the width direction is matched with the dimension of the drainage channel 12.

For better heat conduction and more stable supporting and fixing effect on the heating wire, two heat conduction brackets 2, namely a first heat conduction bracket 23 and a second heat conduction bracket 24, are arranged in each drainage channel 12, and 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 region 25 is formed between the first thermally conductive support 23 and the second thermally conductive support 24.

The provision of the bracket body 22 extending in the width direction in the above-described embodiment, while facilitating the production of the thermally conductive bracket 2, does not facilitate the convergence of water toward the drain passage 12. Since the tray body 11 has a length direction and a width direction, and the first slope bottom surface 111 and the second slope bottom surface 112 having different slopes are formed at the bottom of the tray body 11 in the length direction, since the first slope bottom surface 111 and the second slope bottom surface 112 are both obliquely disposed in the length direction, water flow mainly converges toward the inside of the drain passage 12 along the first slope bottom surface 111 and the second slope bottom surface 112. Due to the existence of the bracket body 22 and the bracket body 22 arranged along the width direction in the water gathering process, that is, the bracket body 22 is perpendicular to the water flow direction, the bracket body 22 has a blocking effect on the water flow, and the blocking effect is particularly significant for the scheme of arranging two heat-conducting brackets 2 in one drainage channel 12. As shown in fig. 6 or 7, only a small amount of water flows through the water flow blocking region 25 between the first heat-conducting support 23 and the second heat-conducting support 24, the first heat-conducting support 23 and the second heat-conducting support 24 block the water flow, the water flow flowing in the longitudinal direction cannot directly flow to the region, and only can be wound from the side, so that the drainage channel is reduced, and the drainage of the water flow is affected. The region corresponding to the water flow blocking region 25 has no drainage function, and therefore, the arrangement of this structure is to actually reduce the size of the drainage cross section of the drainage passage 12, which has an influence on the smoothness of drainage.

In order to solve the technical problem, the drainage channel 12 has a water inlet arranged at the bottom of the water pan 1, a through hole 220 penetrating through the bracket body is arranged on the bracket body 22 opposite to the water inlet, and the height of the through hole 220 in the vertical direction is not lower than the height of the water inlet. The through hole 220 is provided in plural, and the through holes 200 are provided at intervals in the width direction.

At support body 22 above-mentioned perforation that sets up, when support body 22 extended the setting along perpendicular to length direction, did not cause the rivers that assemble on the length direction to block and influence, the rivers that assemble on the length direction can enter into the clearance between two support bodies through the perforation to avoided because of support body 22 inserts the serious situation of effective drainage size reduction that causes drainage channel 12 in drainage channel 12.

In the above embodiment, the bracket body 22 is arranged to extend in parallel with the width direction, and in another embodiment, the bracket body 22 may also be a metal plate arranged to extend in parallel with the length direction of the water collector 1. The bracket body 22 is arranged to extend in a direction parallel to the length direction of the water pan 1, and at this time, the bracket body 22 is arranged perpendicular to the positioning portion 21. The arrangement of the structure reduces the blocking effect of the bracket body 22 on the water flow in the length direction of the water tray 1, which is the main direction of water collection in the water tray 1, so that the drainage of the drainage channel 12 can be reduced more.

The invention further discloses refrigeration equipment, which comprises a box body, an inner container arranged on the box body, an evaporator arranged in the inner container, a heating wire and the water pan assembly, wherein the water pan assembly is arranged on the lower side of the evaporator, the heating wire is provided with a first section providing heat for the evaporator and a second section extending into the water pan, and the second section is positioned on the heat conduction support.

The construction, features and functions of the present invention are described in detail in the embodiments illustrated in the drawings, which are only preferred embodiments of the present invention, but the present invention is not limited by the drawings, and all equivalent embodiments modified or changed according to the idea of the present invention should fall within the protection scope of the present invention without departing from the spirit of the present invention covered by the description and the drawings.
