Description

Refrigerator with door inner compartment

Technical Field

The invention belongs to the technical field of refrigerators, and particularly provides a refrigerator with a door inner chamber.

Background

A refrigerator is a refrigerating apparatus capable of freezing and refrigerating food materials. The existing food materials to be frozen are various, such as raw food materials of chickens, ducks, fishes, shrimps and the like, cooked food materials of steamed bread, steamed rolls, steamed stuffed buns and the like, and cold drink materials of ice cream, ice cream and the like. Raw food materials are often stored for a long time, cooked food materials are often stored for a short time, and cold drink materials are often stored intermittently.

In life, the edible materials stored in a short time are frequently eaten, for example, the cooked wheaten food is eaten basically every meal, and the freezing chamber door of the refrigerator is frequently opened, so that the temperature fluctuation in the freezing chamber is large, and further raw edible materials such as chickens, ducks, fishes and shrimps are repeatedly thawed and frozen, and the quality of the raw edible materials in long-time storage is affected.

To overcome the above problems, some refrigerators provide a refrigerator door (e.g., a freezer door) as a door-in-door. Specifically, the refrigerator door includes a main door defining an inner door compartment and a vent for communicating the inner door compartment with the freezing compartment, and a sub door installed at an outer side of the main door and for closing the inner door compartment. Food materials (e.g., pasta) that require short-time freezing are placed in the door compartment, and food materials that require long-time freezing are placed in the freezer compartment. When a user needs to take out food materials frozen in a short time, the user only needs to open the auxiliary door on the refrigerator door, so that the phenomenon that the freezing compartment is more in loss of cooling when the whole refrigerator door is opened is avoided, and the quality of raw food materials stored for a long time is ensured.

However, in the process of using the refrigerator, condensed water/condensed water is often generated in the door inner compartment, and accumulated at the bottom of the door inner compartment, so that the condensed water/condensed water cannot be discharged, and the condensed water/condensed water needs to be manually erased by a user, thereby affecting the use experience of the user.

As shown in fig. 1 and 2, an in-box compartment 110 and a press bin 120 are defined in the case 100, and the in-box compartment 110 is used for placing food materials and providing a low-temperature freezing/refrigerating environment for the food materials.

Although not shown in the drawings, in some embodiments of the present invention, the refrigerator further includes a compressor, a condenser, an evaporating dish, etc., disposed in the press bin.

As shown in fig. 2 and 3, in some embodiments of the present invention, the case 100 further includes a drain groove 130 provided on a sidewall of the inter-chamber 110. The cabinet 100 further includes a cabinet drain pipe 140, one end of the cabinet drain pipe 140 is fluidly connected to the drain tank 130, and the other end of the cabinet drain pipe 140 extends above or into an evaporation pan (not shown) of the refrigerator.

Referring back to fig. 1, in some embodiments of the invention, a refrigerator door 200 is used to shield the in-box compartment 110. As can be seen from fig. 1, the compartment 110 on the upper side of the refrigerator is configured as a split type refrigerator door 200, i.e., two refrigerator doors 200 jointly shield and open one compartment 110 in a split manner.

In addition, in other embodiments of the present invention, one skilled in the art may also cause one refrigerator door 200 to individually shield one in-box compartment 110 as desired. Further, when the refrigerator is provided with at least two in-box compartments 110, one of ordinary refrigerator doors may be provided for one part of the in-box compartments 110 and the refrigerator door 200 according to the present invention, as required.

Further, in the present invention, when the refrigerator is provided with one in-box compartment 110, the one in-box compartment 110 may be a freezing compartment, a refrigerating compartment, or a temperature changing compartment; when the refrigerator is configured with two in-box compartments 110, the two in-box compartments 110 may be a freezing compartment and a refrigerating compartment; when the refrigerator is configured with at least three in-box compartments 110, the at least three in-box compartments 110 may include a freezing compartment, a refrigerating compartment, and a temperature changing compartment.

As shown in fig. 4 to 6, in some embodiments of the present invention, the refrigerator door 200 includes a first door 210, a second door 220, a drain valve 230, a door drain pipe 240, a door evaporator 250, and a door fan 260.

The first door 210 includes a mounting portion (not shown) so that the first door 210 is pivotally mounted on the case 100 through the mounting portion. Preferably, the mounting portion is pivotally mounted to the case 100 by a hinge.

As shown in fig. 4 to 6, the first door 210 includes a protrusion 211 protruding into the in-box compartment 110. The first door 210 defines an inner door compartment 212 and a door refrigeration compartment 213 therein. The door inner compartment 212 and the door body cooling compartment 213 communicate with each other. The second door 220 serves to shield the door inner compartment 212. The drain valve 230 is installed on the boss 211, one end of the door drain pipe 240 is fluidly connected to the door refrigerating compartment 213, and the other end of the door drain pipe 240 is fluidly connected to the drain valve 230. The door evaporator 250 and the door fan 260 are both disposed in the door refrigerating compartment 213, the door evaporator 250 is used to cool air flowing therethrough, and the door fan 260 is used to drive the cooled air to flow into the door compartment 212, refrigerating the door compartment 212.

In addition, in other embodiments of the present invention, a door fan 260 may be provided at the junction between the door inner compartment 212 and the door refrigerating compartment 213 as required by those skilled in the art.

Although not shown in the drawings, in some embodiments of the present invention, a drain port is formed at the bottom of the door refrigerating compartment 213, and one end of the door drain pipe 240 is fluidly connected to the drain port to commonly drain the liquid in the refrigerator door 200 through the door drain pipe 240 and the drain valve 220.

Preferably, the one end of the door drain 240 is plugged together with the drain in a sealed manner.

Alternatively, the bottom of the door inner compartment 212 communicates with the bottom of the door body refrigerating compartment 213 so that the liquid in the door inner compartment 212 can flow into the door body refrigerating compartment 213 and then be discharged out of the refrigerator door 200 through the drain valve 230 and the door body drain pipe 240.

Those skilled in the art will appreciate that the liquid within the refrigerator door 200 includes, but is not limited to, at least one of condensed water, dew water, defrost water, food material juice. When the liquid in the refrigerator door 200 includes defrost water, the refrigerator is configured to defrost the door evaporator 250. When the door evaporator 250 is defrosted, the door evaporator 250 can be used as a condenser to melt the frost thereon; alternatively, the door evaporator 250 may be heated by a heating device (e.g., an electric heating wire) to melt frost thereon.

Based on this, in other embodiments of the present invention, the water discharge port may be provided at the bottom of the door inner compartment 212 as required by those skilled in the art on the premise that the bottom of the door inner compartment 212 communicates with the bottom of the door body cooling compartment 213.

As shown in fig. 7 and 8, in some embodiments of the present invention, the drain valve 230 includes a valve body 231, a valve spool 232, a spring 233, and a seal ring 234. The valve body 231 is mounted on the first door body 210, and a flow guide passage 2311 is formed in the valve body 231. The valve spool 232 is slidably coupled to the valve body 231. A spring 233 is provided between the valve body 231 and the valve body 232. The sealing ring 234 is fixedly sleeved on the valve core 232.

When the refrigerator door 200 is closed, the valve core 232 is pressed by the refrigerator body 100, thereby overcoming the elastic force of the spring 233 and thus causing the sealing ring 234 to open the guide passage 2311; when the refrigerator door 200 is opened, the valve core 232 drives the sealing ring 234 to block the diversion channel 2311 under the action of the spring 233.

In addition, in other embodiments of the present invention, one skilled in the art may omit the configuration of the sealing ring 234 and configure the valve core 232 to be capable of abutting against the valve body 231, thereby directly opening or blocking the diversion channel 2311, as required.

Alternatively, one skilled in the art may also secure the seal ring 234 to the valve body 231 such that the seal ring 234 no longer moves with the movement of the valve spool 232, as desired.

As shown in fig. 7, the valve body 231 includes a first valve body 2312 and a second valve body 2313, and an inner diameter of the first valve body 2312 is larger than an inner diameter of the second valve body 2313. The valve body 231 is inserted together with the door drain pipe 240 through the first valve body 2312. Further, the valve body 231 further includes an inner conical surface (not labeled in the drawing) formed between the first valve body 2312 and the second valve body 2313, so that the valve body 231 abuts against the sealing ring 234 through the inner conical surface, so as to ensure that the sealing ring 234 can block the diversion channel 2311.

With continued reference to fig. 7, the spool 232 includes a first spool portion 2321 located within the first valve body portion 2312 and a second spool portion 2322 extending through the second valve body portion 2313, the first spool portion 2321 having a diameter greater than the diameter of the second spool portion 2322 to prevent the spool 232 from exiting the valve body 231 from the second valve body portion 2313.

Further, as shown in fig. 7, the valve body 232 is abutted against the spring 232 by the first valve body portion 2321. Preferably, an annular shoulder (not shown) is provided on the first spool portion 2321, by means of which shoulder the first spool portion 2321 abuts the spring 233.

Still further, as shown in fig. 7, one end of the first valve body portion 2321 near the second valve body portion 2322 is provided as an outer tapered surface (not labeled in the drawing) that matches the seal ring 234. The end of the second spool portion 2322 adjacent to the first spool portion 2321 is provided with a stop surface (not labeled in the drawing). In other words, a clamping groove is formed between the first valve body portion 2321 and the second valve body portion 2322. The seal ring 234 is clamped in the clamping groove, and in fig. 7, the bottom end of the seal ring 234 abuts against a stop surface on the second valve core portion 2322, the inner surface of the seal ring 234 abuts against an outer conical surface on the first valve core portion 2321, and in fig. 7, the top end of the seal ring 234 abuts against a shoulder on the first valve core portion 2321.

As can be seen in fig. 7, in some embodiments of the invention, the seal ring 234 is of a tapered configuration.

With continued reference to fig. 7, the bottom of the door drain pipe 240 is inserted into the first valve body portion 2312 of the valve body 231, and a portion of the door drain pipe 240 near the bottom end thereof is provided as a necking section (not labeled in the drawing). The spring 233 is simultaneously sleeved on the first valve core portion 2321 and the outside of the necking section, and one end of the spring 233 is abutted against a shoulder on the first valve core portion 2321, and the other end of the spring 233 is abutted against an annular surface (not labeled in the figure) at the bottom end of the necking section on the door body drain pipe 240.

Further, as shown in fig. 7, a stop structure (not labeled in the drawing) is further provided on the door drain pipe 240, and the stop structure abuts against an end of the first valve body 2312 away from the second valve body 2313, so as to limit the maximum length of the door drain pipe 240 inserted into the first valve body 2312.

In some embodiments of the present invention, during the assembly of the drain valve 230, the sealing ring 234 is first sleeved on the outer side of the valve core 232, then the valve core 232 and the spring 233 are sequentially inserted into the valve body 231, and finally the gate drain pipe 240 is inserted into the valve body 231. It follows that in some embodiments of the present invention, the assembly of the drain valve 230 is simple.

Preferably, as shown in fig. 8, an L-shaped catching groove 2314 is provided on a sidewall of the top of the valve body 231, and accordingly, a protruding catching block 241 is provided on an outer side of a circumferential wall of the door drain pipe 240. In the process of inserting the door drain pipe 240 into the valve body 231, the clip 241 is aligned with the vertical portion of the clip groove 2314 and inserted into the clip groove 2314, and then the door drain pipe 240 or the valve body 231 is rotated so that the clip 241 is inserted into the lateral portion of the clip groove 2314, thereby fixing the valve body 231 and the door drain pipe 240 together.

The operation of the drain valve 230 in some embodiments of the present invention will be described in detail with reference to fig. 9 and 10.

As shown in fig. 9, when the refrigerator door 200 is closed, particularly after the refrigerator door 200 is completely closed, a portion of the drain valve 230 is inserted into the drain groove 130 on the case 100. And, the valve body 232 is pressed by the case 100 to move toward the door drain pipe 240 against the elastic force of the spring 233, separating the sealing ring 234 from the inner tapered surface of the valve body 231, and thus opening the guide passage 2311. At this time, the liquid in the refrigerator door 200 flows into the drain tank 130 through the door drain pipe 240 and the drain valve 230, and then flows into the evaporation pan in the press bin 120 through the box drain pipe 140.

As shown in fig. 10, as the refrigerator door 200 is opened, the drain valve 230 gradually moves away from the side wall of the case 100, thereby causing the spring 233 to drive the valve core 232 to move in a direction of blocking the flow guide passage 2311 (a direction away from the door drain pipe 240) until the valve core 232 is disengaged from the side wall of the case 100, and thus the sealing ring 234 is abutted against the inner tapered surface on the valve body 231.

It will be appreciated by those skilled in the art that by providing the seal ring 234 with a tapered shape and mating the inner tapered surface on the valve body 231 with the tapered seal ring 234, the seal ring 234 is provided with sufficiently long mating dimensions both axially and radially to ensure that the seal ring 234 blocks the flow-directing channel 2311.

As can be seen in fig. 9 and 10, the drain valve 230 is located at or near the same side (left or right) of the refrigerator door 200 as the mounting portion of the refrigerator door 200 (or the pivot axis of the refrigerator door). Also, when both the drain valve 230 and the mounting portion of the refrigerator door 200 are located at or near the left side of the refrigerator door 200, the left side wall of the in-box compartment 110 is provided with the drain groove 130 corresponding to the drain valve 230; when both the drain valve 230 and the mounting portion of the refrigerator door 200 are located at or near the right side of the refrigerator door 200, the right side wall of the in-box compartment 110 is provided with the drain groove 130 corresponding to the drain valve 230.

Further, if both of the two split-type refrigerator doors 200 provided on the refrigerator have an in-door compartment, the drain valve 230 on the left side refrigerator door 200 and the installation portion of the refrigerator door 200 are located at or near the left side of the refrigerator door 200, and the left side wall of the in-door compartment 110 is provided with the drain groove 130 corresponding to the drain valve 230; the drain valve 230 on the right refrigerator door 200 and the mounting portion of the refrigerator door 200 are located at or near the right side of the refrigerator door 200, and the right side wall of the in-tank compartment 110 is provided with the drain groove 130 corresponding to the drain valve 230.

As can be readily seen from fig. 4, 5, 9 and 10, in some embodiments of the present invention, the drain valve 230 is installed obliquely upward and downward on the first door 210, and the depth direction of the drain tank 130 coincides with the oblique direction of the drain valve 230 to ensure that the drain valve 230 and the liquid in the drain tank 130 can flow under their own gravity.

Preferably, as shown in fig. 11, in some embodiments of the present invention, the trigger direction of the drain valve 230 (i.e., the sliding direction of the valve body 232) is parallel to a tangent line (straight-line-type dash-dot line in fig. 11) of a rotation path (straight-line-type dash-dot line in fig. 11) in which the drain valve 230 moves with the rotation of the refrigerator door 200. And, the bottom wall of the drain tank 130 is perpendicular to the trigger direction of the drain valve 230, so that the drain valve 230 is only subjected to axial force, but not radial force when triggered by the bottom wall of the drain tank 130, the drain valve 230 is prevented from being subjected to moment action, the drain valve 230 (particularly the valve core 232) is prevented from sliding relative to the bottom wall of the drain tank 130, friction noise is prevented from occurring, and the service life of the drain valve 230 is prolonged.

In addition, in other embodiments of the present invention, one skilled in the art may omit the provision of the gate drain pipe 240 and provide the drain valve 230 with a stopper member mounted on the valve body 231 to prevent the spring 233 from escaping, as required. For example, the stopper member is an annular member, and an external thread is provided on an outer peripheral surface of the annular member, and the first valve body portion 2312 of the valve body 231 is provided with an internal thread, and is screwed to the valve body 231 by the internal thread and the external thread and abuts against the spring 233. Further, the drain valve 230 is directly fluidly connected to the door inner compartment 212 or the door body cooling compartment 213. Illustratively, an end of the first valve body 2312 remote from the second valve body 2313 extends to the bottom of the inter-door chamber 212 or the door refrigerating chamber 213.
