Detailed Description

Fig. 1 is a side view of a refrigerator 10 having a drain pipe 130 according to an embodiment of the present invention, fig. 2 is an exploded view of the refrigerator 10 having a drain pipe according to an embodiment of the present invention (in order to show an internal structure of the refrigerator 10, a door body and a heat insulation layer are hidden), and fig. 3 is a side view of a lower portion of the refrigerator 10 having a drain pipe according to an embodiment of the present invention. The refrigerator 10 of the present embodiment changes the position of the evaporator 210 in the refrigeration system from the rear portion of the storage compartment 220 to the bottom portion of the storage compartment 220, and changes the vertical installation manner of the evaporator 210 to the horizontal placement manner, thereby increasing the height of the storage compartment 220 and facilitating the operation of the user. And since the evaporator 210 is not disposed at the back, the utilization efficiency of the storage space of the refrigerator 10 is improved. In addition, the compressor 214 and the condenser are disposed at the lower rear portion of the evaporator 210, so that the storage compartment 220 at the bottom is flat, and the space utilization rate of the storage space of the refrigerator 10 is improved.

The refrigerator 10 of the present embodiment may include: a cabinet 200, a door 230, a refrigeration system, etc. Wherein the case 200 includes: the refrigerator comprises a box body shell 201, a storage inner container 202, a heat insulation layer 203 and other accessories, wherein the box body shell 201 is an outer layer structure of the refrigerator 10 and protects the whole refrigerator 10. In order to isolate heat conduction from the outside, a heat insulation layer 203 is arranged between the box body shell 201 and the box body inner container 202, and the heat insulation layer 203 can be processed through a foaming process.

The housing 200 defines at least one, and typically a plurality of, storage compartments 220 open at the front, such as a refrigerating compartment, a freezing compartment, a warming compartment, and the like. The number and function of the storage compartments 220 can be configured according to the requirement in advance, the number and configuration of the storage compartments 220 and the function of each storage compartment 220 can be configured according to the specific situation in the embodiment, and generally, the storage compartment 220 with the bottom close to the evaporator 210 can be used as a freezing compartment.

The case 200 may further define a cooling chamber 211 for disposing the evaporator 210. The evaporator 210 is disposed in the cooling chamber 211 in a flat cubic shape, i.e. the long and wide sides of the evaporator 210 are parallel to the horizontal plane, the thickness side is perpendicular to the horizontal plane, the evaporator 210 is parallel to the ground as a whole, and the thickness is significantly smaller than the length and width of the evaporator 210.

The cooling chamber 211 is located at the bottom of the inner side of the storage liner 202; a compressor compartment 213 is also formed at the rear portion of the lower portion of the storage bladder 202. A compressor 214 and a condenser (not shown) are disposed in laterally spaced relation within the compressor bin 213. A radiator fan (not shown) is provided between the condenser and the compressor 214. The heat sink fan causes a heat sink airflow to flow through the condenser and compressor 214 to dissipate heat.

The refrigeration system may be a refrigeration cycle system composed of a compressor 214, a condenser, a throttling device (not shown), an evaporator 210, and the like. The evaporator 210 is configured to provide cold energy into the storage compartment 220, and the cold energy can be transferred through an air path system and circulated through a fan. Since the refrigeration system itself is well known and easily implemented by those skilled in the art, the operation principle of the refrigeration system will not be described in detail hereinafter in order to avoid obscuring and obscuring the utility model of the present application.

The air supply duct 215 may be disposed at the back of the storage inner container 202, and has an air inlet disposed in the cooling chamber 211 and an air outlet disposed at the back of the storage compartment 220, and the air inlet is provided with an air supply fan 212 for generating a cooling air flow. The supply air duct 215 distributes the cooling air flow to allow the storage compartments 220 to reach respective set temperatures. The blower fan 212 may be located in the cooling chamber 211 and obliquely disposed at the rear side of the evaporator 210.

The blower fan 212 is provided obliquely behind the evaporator 210, and the blower fan 212 is entirely inclined. Therefore, the height space occupied by the air supply fan 212 is reduced, the height space occupied by the cooling chamber 211 is reduced, and the storage volume of the storage compartment 220 at the upper part of the cooling chamber 211 is ensured.

The return air flow of the storage compartment 220 enters the cooling compartment 211 from the air return opening 216 formed in the front portion of the cooling compartment 211, and exchanges heat with the evaporator 210. During the heat exchange process, the surface of the evaporator 210 may be condensed and frosted. Therefore, the evaporator 210 may be further provided with a heating device such as a heating wire. When defrosting is required, the heater wire is heated to defrost the frost attached to the evaporator 210. The heating wires may be embedded in the channels formed by the plurality of fin notches of the evaporator 210, or may be integrally disposed at the top and bottom of the evaporator 210, so as to directly heat the evaporator 210, thereby improving the defrosting effect.

In order to smoothly guide out the condensed water or the defrosted water, a water receiving tray 110 may be formed on the bottom wall of the cooling chamber 211 for receiving the water dropping from the evaporator 210, and a water outlet 111 is formed at the bottom of the water receiving tray 110. In some embodiments, the drip tray 110 may be a recessed structure disposed below the evaporator 210.

A recessed drip tray 110 is formed below the evaporator 210, and the refrigerator 10 may further include an evaporator pan 120 and a drain 130. The evaporation pan 120 is disposed at the bottom of the condenser in the compressor compartment 213 to evaporate the water in the evaporation pan 120 by the heat of the condenser and to accelerate the efficiency of the evaporator 210 by the heat dissipation airflow.

The evaporation pan 120 is integrally disposed below the water receiving tray 110. The drain pipe 130 is connected between the drain port 111 and the evaporation pan 120, and guides the water in the water receiving tray 110 to the evaporation pan 120. The cooling chamber 211 and the compressor bin 213 are provided with a heat insulation layer 203, the water drainage pipe 130 can obliquely penetrate through the heat insulation layer 203 and enter the compressor bin 213, and the water can naturally flow into the evaporating dish 120 by utilizing the inclination angle of the water drainage pipe 130. For example, the inclination angle of the drain pipe 130 may be set to an angle of 5 ° or more and 10 ° or less with respect to the horizontal plane, and this inclination angle setting is considered in consideration of the drainage angle and the space compactness of the drain pipe 130.

In order to avoid the situation that the drain port 111 is located close to the supply fan 212, it may cause the supply fan 212 to be heavily condensed or even frozen. The drain opening 111 may be located below the front of the evaporator 210, for example, the ratio of the horizontal distance of the drain opening 111 from the front end of the evaporator 210 to the horizontal distance of the drain opening 111 from the rear end of the evaporator 210 is greater than 1/6 and less than 1/2. For example, the ratio of the horizontal distance of the drain port 111 from the front end of the evaporator 210 to the horizontal distance of the drain port 111 from the rear end of the evaporator 210 may be 1/3, i.e., the drain port 111 is located below the front third of the evaporator 210. Thereby, the drain port 111 is kept away from the air supply fan 212, and even if hot and humid air enters the cooling chamber 211 from the drain port 111, condensation at the air supply fan 212 can be avoided.

Fig. 4 is a schematic view of an inner portion of the drain pipe 130 extending into the evaporating dish 120 in the refrigerator 10 having the drain pipe according to an embodiment of the present invention. Fig. 5 is an enlarged schematic view of the end of the drain pipe 130 in the refrigerator 10 having the drain pipe according to an embodiment of the present invention.

Since the distance between the cooling chamber 211 and the compressor compartment 213 is relatively short in the refrigerator 10 of the present embodiment, the hot and humid air in the compressor compartment 213 is easily introduced into the cooling chamber 211 from the drain pipe 130, causing the bottom of the evaporator 210 to be frozen. And the humid and hot air of the compressor compartment 213 has a higher humidity and a higher temperature than the air flow returned from the storage compartment 220, so that the formed ice cubes are not easily melted by the heating wire, and when the ice cubes fall down on the water outlet 111, the water outlet 111 is blocked, thereby causing a hidden danger to the refrigerating performance and the safety performance of the refrigerator 10.

Based on the above problem, the portion of the drain pipe 130 extending into the evaporating dish 120 may include: an extension pipe section 131 and a terminal pipe section 132 connected to the extension pipe section 131 and located at the terminal end of the drain pipe 130, the terminal pipe section 132 having an inner diameter of 10 to 50% of the inner diameter of the extension pipe section 131, thereby reducing the size of the outlet of the drain pipe 130. In some more preferred embodiments, the inner diameter of the terminal tube section 132 is 20% to 40%, such as 30%, of the inner diameter of the extension tube section 131. The proportional relation can ensure that water is smoothly discharged, and is beneficial to forming sealing structures such as water seal and the like. Since the end pipe section 132 of the drain pipe 130 is tapered, the flow area of the hot and humid air from the compressor compartment 213 into the cooling chamber 211 can be reduced while ensuring the normal outflow of the condensed or defrosted water.

A transition pipe section 133 is also arranged between the end pipe section 132 and the extension pipe section 131, the inner diameter of the transition pipe section 133 is tapered along the drainage direction to form a funnel shape, and water is prevented from accumulating at the top of the end pipe section 132 by the transition pipe section 133, so that the water can naturally flow down.

The float 114 is arranged in the extension pipe section 131 above the transition pipe section 133, and the bottom profile of the float 114 is adapted to the inner diameter shape of the transition pipe section 133. The float 114, which is less dense than water, can rise using the buoyancy of the water to open the transition duct section 133. The water level of the evaporation pan 120 is raised and the floating body 114 is lifted up after entering the end of the drain pipe 130, so that water sealing can be achieved. When the water level in the evaporation pan 120 is low and no water flows down, the floating body 114 falls down to form a seal with the pipe wall of the transition pipe section 133.

The end pipe section 132 and the transition pipe section 133 may both be vertically disposed. A water storage part 115 is formed at the bottom of the water pan 110, and the end pipe segment 132 is inserted into the water storage part 115, so that the discharged water is stored in the water storage part 115 and overflows into the evaporation pan 120. The entirety of the terminal pipe segment 132 is located within the reservoir 115. The water level of the water storage part 115 is higher than that of the evaporation pan 120, and the end of the drain pipe 130 can be sealed by water.

The configuration of the float 114 and reservoir 115 may be selected as desired, and in some embodiments only the float 114 may be used, or only the reservoir 115 may be used; in other embodiments, both the float 114 and the reservoir 115 may be provided.

Fig. 6 is a side view schematically illustrating a lower portion of the refrigerator 10 having a drain pipe according to another embodiment of the present invention. The refrigerator 10 may further include a drain pump 140, and the drain pump 140 is connected to the drain pipe 130 to pump the water from the water receiving tray 110 into the evaporation pan 120. The drain pump 140 may be installed in the evaporation pan 120 and be turned on when it is necessary to pump water (e.g., when defrosting). In normal operation, drain pump 140 is turned off to close drain 130 and prevent hot and humid air from entering cooling compartment 211.

When the drainage pump 140 is used, the water receiving tray 110 under the evaporator 210 can be a flat surface or the water receiving tray 110 can be directly omitted, and when the evaporator 210 defrosts, defrosted water is accumulated on the bottom wall of the cooling chamber 211; after the defrosting is finished (or during the defrosting process), the drain pump 140 is turned on, and the defrosting water flows into the evaporation pan 120 through the drain pipe 130 and the drain pump 140.

The structure can ensure that the bottom of the evaporator 210 and the fan blade do not frost. The water pan 110 at the bottom of the evaporator 210 can be made into a plane or a plane with a smaller inclination angle, so that the mold cost of the refrigerator 10 production can be saved, and the process cost can be reduced.

The case 200 may further include: and a back 204 positioned at the back side of the storage liner 202, wherein the back 204 is a part of the box body shell 201. A separation plate extending obliquely forward from the back 204 to form a top wall of the compressor compartment 213. The divider plate, which may also be referred to as a bottom cylinder, has its upper side foamed to form the insulation 203 and its lower side defining the compressor compartment 213.

The refrigerator 10 of the embodiment may further include a connection seat 112 and a protection plate 113, wherein the connection seat 112 is attached to the outer side of the bottom of the water-receiving tray 110, and a drain pipe 130 is connected to a position opposite to the drain port 111, so that the water in the water-receiving tray 110 is guided to the evaporation pan 120 by the drain pipe 130. The drain pipe 130 is installed at the drain port 111 of the water collector 110 by using the connection seat 112 attached to the outer side of the bottom of the water collector 110, so that the installation and fixation structure is simple and reliable. The protection plate 113 is attached to the connecting edge of the connecting seat 112 and the water receiving tray 110 to prevent the foaming material from overflowing into the cooling chamber 211 when the box 200 is foamed, thereby preventing the quality problem caused by the overflowing.

The connecting base 112 has an outer shape facing the water-receiving tray 110, which is adapted to the bottom of the water-receiving tray 110, such as a disc shape. The protection sheet 113 may be made of aluminum foil and is adhered to the connection edge of the connection seat 112 and the water-receiving tray 110.

The drain pipe 130 of the refrigerator 10 of the present embodiment may also use a hose, which may be bent and squeezed to some extent, and both ends of the hose are connected to the water tray 110 and the compressor housing 213, respectively. The hose can compensate the position deviation of installation through warping, reduces the installation degree of difficulty. For example, the drain pipe 130 may include: an upper section 136, a bellows section 137, a lower section 138. The upper end of the upper section 136 is fixed to the connection socket 112 and extends obliquely downwards through the insulation layer 203 between the cooling chamber 211 and the compressor bin 213, i.e. the upper section 136 acts as a pipe section connected to the connection socket 112. The upper end of the bellows section 137 is connected to the lower end of the upper section 136 and extends to the evaporation pan 120. And a lower section 138, an upper end of which is connected to a lower end of the bellows section 137, for discharging water into the evaporation pan 120. Thereby reducing installation difficulty with the bellows segment 137.

The bellows segment 137 may be replaced with a tube that is bent to some extent or is stretched or compressed along its length.

The upper end of the bellows segment 137 is provided with a bayonet 151, the lower end of the upper segment 136 is provided with a chuck 152, and after the upper end of the bellows segment 137 is sleeved on the lower end of the upper segment 136, the chuck 152 is clamped with the bayonet 151, so that the bellows segment 137 is clamped with the upper segment 136. The bellows segment 137 is fixed by a clamping structure, and is simple to install and firm to fix.

The upper section 136 is provided with a flange 153 and an external thread 154 on both sides of the partition plate, respectively; a fixing ring 156 is fitted to the external thread 154, and the fixing ring 156 is screwed to the external thread 154, so that the partition plate is pressed between the flange 153 and the fixing ring 156. A gasket 155 is also provided on the side of flange 153 opposite the divider plate to prevent the foaming material from spilling into compressor bin 213 when cabinet 200 is being foamed. During screwing of the securing ring 156, the sealing gasket 155 is compressed. The gasket 155 may block the foaming material during foaming.

The lower section 138 may include: an inclined connecting section 134 and a vertical water outlet section 135. The inclined connection section 134 is connected to the lower end of the bellows section 137 and extends in the length direction of the bellows section 137; and a vertical water outlet section 135 connected to a lower end of the inclined connection section 134 and for vertically guiding water into the evaporation pan 120. Because the vertical water outlet section 135 is vertically arranged, the water outlet direction in the water outlet pipe 130 is vertically downward, which facilitates water outlet and water seal.

On one hand, the structure of the water drainage pipe 130 compensates installation deviation by using the deformation of the corrugated pipe section 137, so that the installation difficulty is reduced; on the other hand, the foaming material can be prevented from overflowing into the cooling chamber 211 and the compressor bin 213, and the production quality is improved.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
