Detailed Description

The technical solutions of the present application are described clearly and completely by the following specific examples, and it is obvious that the described examples are some, but not all, of the examples of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Embodiments of the present invention provide one or more refrigeration appliances. The refrigeration appliance provided by the embodiment of the utility model can be a refrigerator, a wine cabinet and the like.

Embodiments of the present invention provide a refrigeration appliance having an evaporator for providing cooling energy into a storage compartment of the refrigeration appliance to maintain the storage compartment at certain temperature and/or humidity conditions. The evaporator is at a low temperature during normal operation and the moisture in the air can frost or freeze on the evaporator. The frost on the surface of the evaporator can affect the operation efficiency of evaporation, and the frost on the surface of the evaporator can be melted by a certain technical means (such as heating). In the prior art, a water pan 3 is arranged below an evaporator, and defrosting water in the water pan 3 is guided to other places by a drain pipe 5. Based on the cost and the requirement of being convenient for the shaping, drain pipe 5 is mostly plastics material. In order to prevent the drain pipe 5 from being clogged with the defrosted water or the frost falling from the evaporator, the heat of the heat source in other places is conducted to the drain pipe 5 through the heat conductive sheet 10. For the convenience of assembly, the heat conduction sheet 10 is mostly movably connected to the drain pipe 5, so that the heat conduction sheet 10 may contact with the wall of the drain pipe 5 due to shaking during transportation and shaking during use. In the use process, the hot heat conducting fins 10 may melt through the wall of the drain pipe 5, or accelerate the deformation and aging of the drain pipe 5, resulting in maintenance cost; moreover, the deformation and damage of the drain pipe 5 can cause the sealing failure of the refrigeration appliance, the phenomena of frosting and icing of the evaporator are aggravated, the energy consumption is increased, and the stable operation is not facilitated.

Refer to fig. 1-2 below.

The refrigeration appliance provided by the embodiment of the utility model comprises a water pan 3, a heater 2, a heat conducting fin 10 and a drain pipe 5; not shown in the drawing, the refrigeration appliance also comprises an evaporator, which is located above the water pan 3.

The heat conducting sheet 10 includes a connecting portion 11 connected to the heater 2 and a main body portion 12 extending into the drain pipe 5, and a supporting portion 13 is provided on the main body portion 12 between the main body portion 12 and the wall of the drain pipe 5.

When the heat conducting strip 10 shakes, the supporting part 13 prevents the main body part 12 of the heat conducting strip 10 from contacting with the wall of the drain pipe 5, less heat can be transferred to the wall of the drain pipe 5, the possibility of penetrating through the wall of the drain pipe 5 is reduced, the service life of the drain pipe 5 is prolonged, and the refrigeration appliance can run efficiently and stably for a long time.

The heat conductivity of the heat conductive sheet 10 can be realized by using a heat conductive material, and the higher the heat conductivity coefficient, the better the heat conductivity of the heat conductive sheet 10 is. The heat conductive sheet 10 may be a metal heat conductive sheet 10, for example, aluminum, iron, copper, etc. may provide good heat conductivity. It will also be appreciated that the metal heat-conducting sheet 10 also has good moldability and can be simply and inexpensively formed into a desired shape.

The heater 2 is used to provide heat to the heat conductive sheet 10, and may be a self-heating device such as a heating wire, an electric heating tube, etc. to generate heat by using electric energy; or a heat conducting device, and heat is conducted from other heating objects.

In one or more specific embodiments, the heater 2 may also provide heat to the evaporator for accelerating the evaporation of frost and ice. In such a scheme, the heater 2 has multiple purposes, and provides heat for the evaporator and the heat conducting fins 10, so that the utilization rate of the heat is higher.

In one or more specific embodiments, the heater 2 comprises a heat-generating tube 21 located between the evaporator and the drip tray 3. The connecting portion 11 of the heat conductive sheet 10 has an inverted U-shaped hook 111, and the hook 111 hooks the heat conductive sheet 10 to the heat pipe 21. The structure is very convenient to assemble, large components such as the water pan 3, the drain pipe 5, the evaporator and the heater 2 can be installed in place, the main body part 12 of the heat conducting fin 10 is inserted into the drain pipe 5, and the connecting part 11 is hung on the heating pipe 21; the space required is also smaller and the refrigeration appliance is more compact.

In one or more specific embodiments, the refrigeration device further includes a metal extension pipe 4, one end of the metal extension pipe 4 extends from the water pan 3 to the drain pipe 5 beyond the position of the supporting portion 13, the metal extension pipe 4 is sleeved on the periphery of the main body portion 12 of the heat conducting fin 10, and the metal extension pipe 4 is located between the supporting portion 13 and the drain pipe 5. In this case, even if the heat conductive sheet 10 is shaken, the main body 12 of the heat conductive sheet 10 does not touch the wall of the drain pipe 5, and the support portion 13 does not touch the wall of the drain pipe 5 due to the metal extension pipe 4.

In one or more specific embodiments, the connecting portion 11 has a certain width (the width direction is d1 direction), the width direction of the connecting portion 11 is consistent with the length direction of the heat generating tube 21, if the heat conducting sheet 10 is to shake in the width direction of the connecting portion 11, the width of the connecting portion 11 can increase the moment to be overcome by the shake, and therefore, the heat conducting sheet 10 is less likely to shake in the width direction of the connecting portion 11 or the length direction of the heat generating tube 21. It is understood that the wider the width of the connecting portion 11, the less likely the rattling occurs in this direction.

Further, the connection portion 11 includes a hook 111 that is matched with the wall surface of the heating tube 21, the heat conductive sheet 10 is hung on the heating tube 21 through the hook 111, and the width direction of the hook 111 coincides with the length direction of the heating tube 21.

In one or more specific embodiments, the extending direction of the supporting portion 13 is perpendicular to the width direction of the connecting portion 11. Due to the limitation of the width of the connecting part 11, the heat-conducting fin 10 is not easy to touch the pipe wall of the drain pipe 5 in the width direction; thus, the support portion 13 is extended to extend perpendicularly to the width direction of the connection portion 11; due to the support portion 13, the main body 12 of the heat conduction sheet 10 does not touch the wall of the drain pipe 5 in the direction perpendicular to the width of the connection portion 11.

In one or more specific embodiments, the width direction (d2) of the thermally conductive sheet 10 coincides with the width direction of the connecting portion 11.

In one or more specific embodiments, the main body of the heat conductive sheet 10 has a first edge 14 and a second edge 15 opposite to each other in the width direction along the length direction, and the two sets of supporting portions 13 are integrally formed with the main body 12 at the first edge 14 and the second edge 15, respectively. The heat conducting sheet 10 is easy to manufacture, can be formed in one step by die pressing, and is simple to manufacture and low in cost.

As a modification, the supporting portion 13 may be provided in not only one set but also more sets.

As a modification, the support portion 13 may be located at the edge of the main body 12 of the heat conductive sheet 10, or may be located in the middle of the heat conductive sheet 10.

As a modification, the support portion 13 may be attached to the main body portion 12. The heat transfer capacity between the support portion 13 and the main body portion 12 is reduced and less heat is transferred to the wall of the drain pipe 5.

Further, the two sets of supporting portions 13 extend in opposite directions perpendicular to the width direction of the main body portion 12. On the one hand, the wobbling of the thermally conductive sheet 10 is restricted in different directions; on the other hand, it is also advantageous to position the main body 12 as far as possible along the axis of the drain pipe 5, so that the heat distribution is more uniform.

In one or more specific embodiments, the main body 12 has a slot 16 extending in the same direction as the main body 12, and the slot 16 is formed by stamping, thereby improving the deformation resistance of the main body 12.
