Description

Refrigerating module for a refrigerating device and refrigerating device

Technical Field

The utility model belongs to the technical field of freezing and refrigerating equipment, and particularly provides a refrigerating module for the freezing and refrigerating equipment and the freezing and refrigerating equipment.

Background

The whole shape, the number of internal compartments and the volume of the internal compartments of the existing refrigerator of the same series are the same, and the refrigerators of different models are often different only in color and the material of the shell. The existing refrigerator cannot meet the demands of wide users due to different families, different decoration styles and different favorites of different users. And manufacturers cannot provide customized refrigerators for users according to the demands of the users. The refrigerator is characterized in that the existing refrigerator generally integrates a refrigerating system on the refrigerator body of the refrigerator, so that manufacturers need to redesign the structure and layout of the refrigerator according to the needs of users, and more molds are needed to be newly opened, so that the production cost of the refrigerator is higher, and the production period is longer.

In order to overcome the above problems, the prior art proposes a modular refrigerator. Specifically, the refrigerator is designed into two independent modules, namely a refrigerator body module and a refrigerating module. The refrigerating module can adapt to various different box modules so as to assemble the refrigerating module and the corresponding box modules together according to the custom-made demands of users.

In order to realize the refrigeration of the refrigeration module to the box module, cold air in the refrigeration module needs to be introduced into the box module, and hot air (relative to the cold air in the refrigeration module) in the box module needs to be introduced into the refrigeration module, so that the circulation is repeated. The existing design generally sets the air return port of the refrigeration module as one, so that the air return resistance of the refrigeration module is large, and the cold leakage is serious.

Disclosure of Invention

An object of the present utility model is to solve the problem of greater resistance to return air of the refrigeration modules in existing modular refrigerators.

A further object of the utility model is to provide a more uniform diffusion of the air entering the refrigeration compartment and thus a uniform flow of the air at a higher temperature through the evaporator.

To achieve the above object, the present utility model provides in a first aspect a refrigeration module for a refrigeration and chiller apparatus including a housing module defining a storage compartment, the refrigeration module comprising:

the shell is internally provided with a press bin and a refrigeration compartment, and the shell is provided with an air return port and an air supply port which are communicated with the refrigeration compartment, so that the shell receives air flow from the storage compartment through the air return port and conveys the air flow to the storage compartment through the air supply port; the air return port comprises a front air return port formed at the top of the front side plate of the shell and a side air return port formed at the left upper part and/or the right upper part of the shell;

a refrigeration system including a compressor and a condenser disposed within the press bin, the refrigeration system further including an evaporator disposed within the refrigeration compartment;

A heat dissipation fan disposed within the press bin;

and the air supply fan is arranged in the refrigerating compartment.

Optionally, the top of the front side plate of the shell is provided with a concave structure which is concave inwards, the bottom wall of the concave structure is inclined backwards from bottom to top, and the front return air inlet is formed on the bottom wall of the concave structure.

Optionally, the front air return opening is a strip-shaped opening extending transversely.

Optionally, a spoiler is arranged on the front side plate of the shell, and the spoiler is inclined backwards from top to bottom from the top end of the front air return opening.

Optionally, at least one of a junction between the top plate and the left side plate of the housing and a junction between the top plate and the right side plate of the housing is provided with the side return air opening.

Optionally, a junction between the top plate and the left side plate of the housing is provided as a bevel; and/or the joint between the top plate and the right side plate of the shell is set to be an inclined plane.

Optionally, the side return air inlet is located at the front of the housing.

The present utility model also provides in a second aspect a refrigeration and chiller apparatus comprising a housing module and a refrigeration module of any of the first aspects, the housing module defining a storage compartment, an air supply duct in communication with the storage compartment, and an air return duct in communication with the storage compartment, the air supply opening of the refrigeration module being fluidly connected to the air supply duct, the front air return opening and the side air return opening of the refrigeration module both being fluidly connected to the air return duct.

Optionally, the storage compartment comprises a first storage compartment and a second storage compartment, the return air channel comprises a first return air channel communicated with the first storage compartment and a second return air channel communicated with the second storage compartment, the first return air channel is far away from one end of the first storage compartment and is in fluid connection with the side return air inlet, and the second return air channel is far away from one end of the second storage compartment and is in fluid connection with the front return air inlet.

Optionally, the refrigerator-freezer is a refrigerator, the first storage compartment is a refrigeration compartment, and the second storage compartment is a freezer compartment.

Based on the foregoing description, it can be appreciated by those skilled in the art that in the foregoing technical solution of the present utility model, the air return port of the refrigeration compartment is configured to include a front air return port formed at the top of the front side plate of the housing and a side air return port formed at the upper left and/or upper right of the housing, so that the refrigeration compartment has a plurality of air return ports, thereby reducing the air return resistance of the refrigeration module.

And, because the trompil direction of preceding return air inlet and side return air inlet is different for the air current that flows in from preceding return air inlet and side return air inlet can interfere each other, stirs each other, thereby makes the relatively stable air current be broken up before getting into the evaporimeter, and the diffusion is more even, and then makes the gaseous flow that each part of evaporimeter contacted roughly the same. Compared with the prior art, only one air return opening is configured for the refrigeration module, so that the air flow blown to the evaporator from the air return opening is concentrated, and the air flow contacted by each part of the evaporator is larger in difference. Meanwhile, the frosting on the evaporator is relatively uniform.

Further, by inclining the spoiler backward from top to bottom from top of the front return air inlet, the air flow blown out from the front return air inlet located at the top of the refrigerating compartment can be blown to the middle of the evaporator, shortening the flow path of the air flow. As will be appreciated by those skilled in the art, the spoiler can act to redirect the airflow, thereby disturbing the airflow, accelerating the diffusion of the airflow, and further causing the flow rates of the gases contacted by the portions of the evaporator to be substantially the same.

Preferably, each spoiler intersects the front side of the evaporator in its front-up-to-rear-down direction of extension to ensure that the air flow blown from the front return air opening is all blown toward the front surface of the evaporator.

The above, as well as additional objectives, advantages, and features of the present utility model will become apparent to those skilled in the art from the following detailed description of a specific embodiment of the present utility model when read in conjunction with the accompanying drawings.

Detailed Description

It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present utility model, but not all embodiments of the present utility model, and the some embodiments are intended to explain the technical principles of the present utility model and are not intended to limit the scope of the present utility model. All other embodiments, which can be obtained by a person skilled in the art without any inventive effort, based on the embodiments provided by the present utility model, shall still fall within the scope of protection of the present utility model.

It should be noted that, in the description of the present utility model, terms such as "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate directions or positional relationships, which are based on the directions or positional relationships shown in the drawings, are merely for convenience of description, and do not indicate or imply that devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Further, it should also be noted that, in the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, and can also be communicated with the inside of two elements. The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.

In addition, it should be noted that, in the description of the present utility model, the terms "cooling capacity" and "heating capacity" are two descriptions of the same physical state. That is, the higher the "cooling capacity" of a certain object (for example, evaporator, air, condenser, etc.), the lower the "heat" of the object, and the lower the "cooling capacity" of the object, the higher the "heat" of the object. Some object absorbs the cold and releases the heat, and the object releases the cold and absorbs the heat. A target maintains "cold" or "heat" to maintain the target at a current temperature. "refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, i.e., a target (e.g., an evaporator) absorbs heat while it is refrigerating.

The refrigeration module of the present utility model will be described in detail with reference to the accompanying drawings in conjunction with a refrigerator.

In the present utility model, the refrigerating and freezing apparatus may have both the refrigerating function and the freezing function, may have only the refrigerating function, and may have only the freezing function. The freezing and refrigerating device may be a refrigerator, freezer or ice chest.

As shown in fig. 1 and 2, in some embodiments of the present utility model, a refrigerator-freezer includes a cabinet module 100 and a refrigeration module 200. The refrigeration module 200 serves to receive gas from the tank module 100, cool the received gas, and then supply the cooled gas to the tank module 100.

In the manufacturing process, the tank module 100 and the refrigeration module 200 may be manufactured separately and then assembled and fixed together.

As shown in fig. 1 and 2, in some embodiments of the present utility model, the case module 100 defines a storage compartment 101, and the storage compartment 101 is configured to receive cold air from the cooling module 200 to cool food materials therein. Further, the storage compartment 101 includes a first storage compartment 1011 and a second storage compartment 1012.

In some embodiments of the utility model, the first storage compartment 1011 is a refrigerated compartment and the second storage compartment 1012 is a freezer compartment.

In addition, in other embodiments of the present utility model, one skilled in the art may set the first storage compartment 1011 as a freezer compartment and the second storage compartment 1012 as a refrigerator compartment as desired; alternatively, the first storage compartment 1011 and the second storage compartment 1012 are all provided as a freezing compartment or a refrigerating compartment; alternatively, at least one of the first storage compartment 1011 and the second storage compartment 1012 may be provided as a temperature changing compartment.

As shown in fig. 2, a first air outlet 10111 is provided on a side wall of the first storage room 1011, so that air in the first storage room 1011 flows to the refrigeration module 200 through the first air outlet 10111. Air within the second storage compartment 1012 flows from the opening of the second storage compartment 1012 to the refrigeration module 200.

Further, although not shown, in some embodiments of the utility model, the case module 100 further includes a first door corresponding to the first storage compartment 1011 and a second door corresponding to the second storage compartment 1012. The first door is used for shielding the first storage room 1011 to prevent external air from entering the first storage room 1011. The second door is used for shielding the second storage compartment 1012 to prevent external air from entering the second storage compartment 1012; the second door also serves to shield the top of the refrigeration module 200, and in particular, the front return 21021 of the refrigeration module 200 (as shown in fig. 5). Further, the inner side of the second door is provided with a sink having a portion aligned with and communicating with the second storage compartment 1012 and a portion aligned with and communicating with the front return air inlet 21021 of the refrigeration module 200, so that air in the second storage compartment 1012 flows to the refrigeration module 200 through the sink.

Furthermore, in other embodiments of the present utility model, a person skilled in the art may also provide a channel on the second door, as desired, with one end of the channel aligned with and in communication with the second storage compartment 1012, and the other end of the channel aligned with and in communication with the front return air inlet 21021 of the refrigeration module 200.

As shown in fig. 2-4, in some embodiments of the present utility model, the tank module 100 includes a first liner 110, a second liner 120, an air supply line 130, and an air return line 140 disposed within its housing (not labeled). Wherein, a first storage compartment 1011 is formed in the first liner 110, and a second storage compartment 1012 is formed in the second liner 120. In other words, the first storage compartment 1011 is defined by the first liner 110, and the second storage compartment 1012 is defined by the second liner 120. An air supply channel 1301 is defined in the air supply pipe 130, and the air supply channel 1301 is respectively communicated with the first storage compartment 1011 and the second storage compartment 1012, so that the box module 100 receives cold air from the refrigeration module 200 through the air supply channel 1301 and delivers the cold air to the first storage compartment 1011 and the second storage compartment 1012.

As shown in fig. 4, a first return air channel 1401 (shown by a dotted line in fig. 4) is formed in the return air duct 140, and a top end of the first return air channel 1401 is communicated with a first air outlet 10111, or the first air outlet 10111 forms an inlet of the first return air channel 1401; so that the tank module 100 delivers air in the first storage compartment 1011 to the refrigeration module 200 through the first return air channel 1401.

As can be seen from fig. 2 to 4, the supply duct 130 and the return duct 140 are arranged in a vertical direction as a whole to reduce wind resistance. And the air supply duct 130 includes a portion located in the first liner 110 and a portion located in the second liner 120.

Furthermore, in other embodiments of the present utility model, the blower line 130 and/or the return line 140 may be angled as desired by one skilled in the art. And, the blower duct 130 may be provided outside the first and second liners 110 and 120 as required by those skilled in the art.

Furthermore, in still other embodiments of the present utility model, one skilled in the art may arrange the storage compartments 101 in any other feasible number, such as one, three, five, six, etc., as desired. Those skilled in the art may also include other numbers of bladders, such as one, three, four, etc., as desired. For example, the housing module 100 may include only one liner and the liner may define one or more storage compartments. When the liner defines only one storage compartment, the storage compartment may be configured to deliver air therein to the refrigeration module 200 in the manner of the first storage compartment 1011 or the second storage compartment 1012 as described above. When the liner defines a plurality of storage compartments, the bottom storage compartment delivers air therein to the refrigeration module 200 in the manner of the second storage compartment 1012 as described above; the other storage compartments adopt the first storage compartment 1011 as described above to convey the air therein to the refrigeration module 200, and each storage compartment may correspond to one return air duct 140 (each return air duct 140 corresponds to one side return air port 21022 (as shown in fig. 5)) respectively, or may share one return air duct 140.

As shown in fig. 4, in some embodiments of the present utility model, the tank module 100 further defines a receiving chamber 102 at a bottom thereof, the receiving chamber 102 for receiving the refrigeration module 200. The receiving chamber 102 has a front opening (not shown) and a bottom opening (not shown) for moving the case module 100 from the rear side of the refrigerating module 200 to above the refrigerating module 200 so as to fix the case module 100 and the refrigerating module 200 together after the case module 100 is moved to a position matched with the refrigerating module 200.

As shown in fig. 5 and 6, in some embodiments of the present utility model, the refrigeration module 200 includes a housing 210, and the refrigeration module 200 further includes a refrigeration system 220, a heat dissipation fan 230, a blower fan 240, and an evaporation pan 250 within the housing 210.

As shown in fig. 5, the casing 210 is provided with an air supply port 2101 and an air return port 2102. Wherein return air inlet 2102 includes a front return air inlet 21021 and a side return air inlet 21022.

As shown in fig. 2, in the assembled state of the refrigerating apparatus, the air supply port 2101 is abutted with the air supply pipeline 130 on the box module 100, so that the refrigerating module 200 supplies air to the air supply pipeline 130 through the air supply port 2101, and the air supply pipeline 130 supplies the cold air received by the air supply pipeline to the storage compartment 101.

As shown in fig. 2 and 3, in the assembled state of the refrigerator, the front return air inlet 21021 and the second storage compartment 1012 are both positioned on the front side of the refrigerator, and both are communicated through a sink or channel formed on the second door (as described above) such that the refrigeration module 200 receives air from the second storage compartment 1012 through the front return air inlet 21021. The side return 21022 interfaces with the return air duct 140 on the cabinet module 100 such that the refrigeration module 200 receives air from the first storage compartment 1011 through the side return 21022.

As shown in fig. 6-8, in some embodiments of the utility model, a press bin 2103, a refrigeration compartment 2104, a heat dissipation air intake channel 2105, and a heat dissipation air outlet channel 2106 are defined within the housing 210. Wherein the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are respectively communicated with the press bin 2103 and respectively extend from the press bin 2103 to the front end of the shell 210.

It should be noted that, for the sake of understanding by those skilled in the art, fig. 7 and fig. 8 schematically show the relative positional relationship and distribution of four spaces of the press cabin 2103, the refrigeration compartment 2104, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106.

As can be readily seen from fig. 7 and 8, the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are all located below the refrigerating compartment 2104, and the outer contour of the projections of the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 on the horizontal plane is located outside the projections of the refrigerating compartment 2104 on the horizontal plane. In other words, if the press house 2103, the heat dissipation air intake passage 2105 and the heat dissipation air outlet passage 2106 are regarded as one whole, the projection of the refrigerating compartment 2104 on the horizontal plane is located inside the projection on the one whole horizontal plane.

As shown in fig. 7 and 8, the supply-air port 2101, the front return port 21021 and the side return port 21022 are respectively communicated with the refrigerating compartment 2104. Wherein the supply-air port 2101 is located at the rear upper side of the refrigerating compartment 2104, the front return air port 21021 is located at the front upper side of the refrigerating compartment 2104, and the side return air port 21022 is located at the side upper side of the refrigerating compartment 2104.

As will be appreciated by those skilled in the art, due to the different directions of the openings of the front return 21021 and the side return 21022, the air flows from the front return 21021 and the side return 21022 are able to interfere with each other and agitate each other, thereby allowing a relatively steady flow of air to be dispersed more evenly before entering the evaporator 226, and thus allowing the air flow to be substantially the same across the various portions of the evaporator 226. At the same time, the frosting on the evaporator 226 is thus also made relatively uniform.

As shown in fig. 6, in some embodiments of the utility model, the refrigeration system 220 includes a compressor 221, a high temperature line 222, a condenser 223, a dry filter 224, a capillary tube 225, an evaporator 226, and an air return 227, which are connected end to end in sequence and thus form a closed loop.

As shown in fig. 6, 9 to 11, the compressor 221, the condenser 223 and the dry filter 224 are all disposed in the press housing 2103, the high-temperature pipeline 222 is distributed in the press housing 2103 and the heat radiation air outlet passage 2106, and the evaporator 226 is disposed in the refrigerating compartment 2104. Most of the tube sections of the capillary tube 225 and the return air tube 227 are located outside the press bin 2103 and the refrigeration compartment 2104. Alternatively, one skilled in the art may also dispose all of the capillaries 225 and/or the return air tubes 227 outside of the press bin 2103 and refrigeration compartment 2104 as desired.

As shown in fig. 6, 13 to 15 and 17, the heat radiation fan 230 is disposed in the press bin 2103, the air supply fan 240 is disposed in the refrigerating compartment 2104, and the evaporating dish 250 is disposed in the heat radiation air outlet passage 2106. At least a portion of the high temperature conduit 222 located within the heat dissipation air outlet channel 2106 is located within the evaporation pan 250 such that the high temperature conduit 222 is capable of heating water within the evaporation pan 250 to facilitate evaporation of the water.

As shown in fig. 13 to 15 and 17, in some embodiments of the present utility model, a lateral gap 21071 is formed between the top plate of each of the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 and the bottom plate of the refrigeration compartment 2104, and the lateral gap 21071 is filled with a thermal insulation material (such as a foaming agent or thermal insulation cotton). A front gap 21072 is formed between the bottom of the front plate of the refrigerating compartment 2104 and the outer plate of the casing 210 adjacent thereto, and the front gap 21072 is filled with a heat insulating material (e.g., a foaming agent or heat insulating cotton). A longitudinal gap 21073 is formed between the left and right side plates of the refrigerating compartment 2104 and the outer side plates of the respective adjacent housings 210, and the longitudinal gap 21073 is filled with a heat insulating material (e.g., a foaming agent or heat insulating cotton). Those skilled in the art will appreciate that the insulating material outside the refrigerated compartment 2104 is effective to insulate the refrigerated compartment 2104 from cold leakage.

Further, the top plates of the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are parallel to the bottom plate of the refrigeration compartment 2104, so that the heat insulation materials in the transverse gap 21071, the front gap 21072 and the longitudinal gap 21073 are uniformly filled with the heat insulation materials with the same thickness, and the refrigeration compartment 2104 is uniformly insulated.

Optionally, the portions of the capillary tube 225 and the air return tube 227 outside the press bin 2103 and the refrigeration compartment 2104 are disposed in the longitudinal gap 21073 and are surrounded by insulation. Preferably, capillary tube 225 and return air tube 227 abut to allow the two to exchange heat. Further, since the temperature of the heat dissipation air intake passage 2105 is lower than the temperature of the heat dissipation air output passage 2106, the capillary tube 225 and the air return tube 227 are preferably arranged in one of the two longitudinal gaps 21073 close to the heat dissipation air intake passage 2105.

As shown in fig. 14 and 15, the refrigeration module 200 further includes a platen 260 disposed between the evaporator 226 and the ceiling of the refrigeration compartment 2104, the platen 260 being used to compress the evaporator 226 against the floor of the refrigeration compartment 2104, thereby securing the evaporator 226 obliquely within the refrigeration compartment 2104.

In some embodiments of the present utility model, the evaporator 226 is disposed obliquely upward in a front-to-rear direction, and the included angle of the evaporator 226 with the horizontal plane ranges from 8 ° to 45 °, such as 8 °, 12 °, 15 °, 20 °, 30 °, 45 °, and so on.

Furthermore, in other embodiments of the present utility model, the evaporator 226 may be placed horizontally, as desired, with the projected area of the evaporator 226 on a horizontal plane being larger than the projected area of the evaporator on a vertical plane.

With continued reference to fig. 14 and 15, in some embodiments of the utility model, the floor of the refrigerated compartment 2104 is provided with a drain hole 2108 below the front of the evaporator 226. The refrigeration module 200 further includes a drain pipe 270 communicating with the drain hole 2108 and extending from above down into the evaporation pan 250 so that the drain pipe 270 can rapidly drain the defrost water in the refrigeration compartment 2104 into the evaporation pan 250.

With continued reference to fig. 14 and 15, the blower fan 240 is located between the evaporator 226 and the air supply port 2101 in the air flow path, and both the evaporator 226 and the blower fan 240 are disposed obliquely within the refrigerating compartment 2104.

As shown in fig. 14, the floor of the refrigerating compartment 2104 includes, at the rear side of the drain hole 2108, an evaporator support section 21041 and a blower support section 21042 extending obliquely rearward and upward, and the inclination angle of the blower support section 21042 is larger than that of the evaporator support section 21041 so that the inclination angle of the blower 240 is larger than that of the evaporator 226. Preferably, the blower fan 240 is a centrifugal fan. The top surface of the centrifugal fan is aligned with the rotation axis of the impeller and the distance between the top plate of the refrigerating chamber 2104 is not less than 30 mm, so that the wind resistance of the centrifugal fan during air suction is reduced.

Wherein the pitch is a distance in the direction in which the axis of the impeller extends.

In addition, the blower fan 240 may be any other possible fan, such as a cross-flow fan, an axial flow fan, etc., as desired by those skilled in the art.

As shown in fig. 14 and 15 and 17, a rear section 21043 of the ceiling of the refrigerating compartment 2104 is inclined downward from front to back, and an air supply port 2101 is formed on the rear section 21043. As can be seen, the air supply opening 2101 is located in the center of the rear section 21043, and the air supply opening 2101 is a rectangular opening extending laterally. As can be seen from fig. 14 and 15, the section of the ceiling of the refrigerating compartment 2104 located on the front side of the air supply port 2101 extends forward in the horizontal direction.

Accordingly, the inlet end of the air duct 130 of the housing module 100 is also inclined such that the inlet end of the air duct 130 is parallel to the rear section 21043.

Returning to fig. 5, in some embodiments of the present utility model, the top of the front side plate of the housing 210 has an inwardly recessed structure 211, the bottom wall of the recessed structure 211 is inclined from bottom to top to back, and the front return air inlet 21021 is formed on the bottom wall of the recessed structure 211. Preferably, the front return air inlet 21021 is a laterally extending strip-shaped opening.

As shown in fig. 16, a spoiler 212 is provided on the front side plate of the housing 210, and the spoiler 212 is inclined backward from top to bottom from the top end of the front return air inlet 21021. Preferably, each spoiler 212 intersects the front side of the evaporator 226 in its front-up-to-rear-down extending direction to ensure that the air flow blown out of the front return air inlet 21021 is all blown toward the front surface of the evaporator 226.

Those skilled in the art will appreciate that by tilting the spoiler 212 rearwardly from top to bottom of the front return air inlet 21021, the air flow from the front return air inlet 21021 at the top of the refrigerated compartment 2104 can be directed toward the middle of the evaporator 226, shortening the flow path of the air flow. Those skilled in the art will also appreciate that because the spoiler 212 can act to redirect the airflow, it can act to disturb the airflow, accelerating its diffusion so that the flow of gas to which the portions of the evaporator 226 are exposed is as substantially the same as possible.

As shown in fig. 5, 9 and 17, the junction between the top side plate and the left side plate of the housing 210 is provided as a slope, and the junction between the top side plate and the right side plate of the housing 210 is also provided as a slope. The side return air inlet 21022 is formed on the right side slope of the housing 210 and is located at the front of the housing 210.

Correspondingly, the outlet end of the return air duct 140 of the tank module 100 is also inclined such that the outlet end of the return air duct 140 is parallel to the right side incline of the housing 210.

Furthermore, in other embodiments of the present utility model, the side return 21022 may be disposed in the middle or rear of the housing 210 as desired by one skilled in the art; and the side return air inlet 21022 is formed on the left inclined surface of the housing 210 as required, and the first air outlet 10111 and the return air duct 140 on the tank module 100 are disposed on the left side of the tank module 100.

In still other embodiments of the present utility model, it is also possible for those skilled in the art to provide the side return air inlet 21022 on the left and right inclined surfaces of the housing 210, respectively, and the first air outlet 10111 and the return air duct 140 on the left and right sides of the cabinet module 100, respectively, as desired. Optionally, the two first air outlets 10111 and the two air return lines 140 correspond to the same storage compartment, or each first air outlet 10111 and each air return line 140 respectively correspond to one storage compartment.

In still other embodiments of the present utility model, one skilled in the art may set only one of the junction between the top side plate and the left side plate of the housing 210 and the junction between the top side plate and the right side plate of the housing 210 to be beveled and set the side return 21022 on the beveled surface as needed.

As shown in fig. 17-19, in some embodiments of the utility model, the housing 210 further includes a wind-guiding member 280, the wind-guiding member 280 for communicating the side return 21022 with the refrigerated compartment 2104. Specifically, the air guide members 280 extend through the longitudinal gap 21073, and the air outlet ends of the air guide members 280 extend to the front side of the evaporator 226.

In some embodiments of the utility model, the side return air inlet 21022 may be in communication with the air inlet end of the air guide member 280 or may be formed on the air inlet end of the air guide member 280.

As shown in fig. 18 and 19, the air guide member 280 includes a lateral opening portion 281 and a longitudinal opening portion 282, and an air intake opening is provided at the top of the lateral opening portion 281, and the opening direction of the air intake opening is inclined upward in the lateral direction (left-right direction of the refrigeration module 200). The air inlet is also provided as a rectangular or strip-shaped opening extending in the front-rear direction. An air outlet is provided at one side of the longitudinal opening 282 in the lateral direction, and is provided as a rectangular opening or a strip-shaped opening extending in the vertical direction. The air outlet of the air guide 280 extends to the front side of the evaporator 226 so that the air flow blown out of the air guide 280 is entirely blown toward the front side of the evaporator 226.

As shown in fig. 10 and 11, the compressor 221, the heat radiation fan 230, and the condenser 223 are sequentially disposed between the heat radiation air outlet passage 2106 and the heat radiation air inlet passage 2105 in the left-right direction of the refrigeration module 200, and the heat radiation fan 230 and the condenser 223 are disposed closely adjacent to each other to reduce the size of the refrigeration module 200 in the lateral direction.

Optionally, the refrigeration module 200 further includes a fixed housing 201 disposed within the press bin 2103, and the heat dissipation fan 230 and the condenser 223 are fixedly connected to the fixed housing 201. Further alternatively, at least a part of at least one of the heat radiation fan 230 and the condenser 223 is embedded in the stationary case 201. Preferably, at least a portion of each of the heat radiation fan 230 and the condenser 223 is embedded in the fixing case 201 such that the air flow passing through the heat radiation fan 230 entirely passes through the condenser 223, thereby improving the heat radiation efficiency of the heat radiation fan 230 to the condenser 223.

As can be seen in fig. 10 and 12, the bottom plates of the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are respectively provided with a gap between the bottom plates and a bearing surface (such as a ground or a floor).

As shown in fig. 10 to 13, the heat dissipation air intake passage 2105 includes a plurality of front air intake openings 21051 formed on a front side plate of the housing 210 so that outside air can enter the heat dissipation air intake passage 2105 from the plurality of front air intake openings 21051. Further, the heat dissipation air intake passage 2105 further includes a plurality of bottom side air inlets 21052 formed on a bottom plate of the heat dissipation air intake passage 2105 so that outside air can enter the heat dissipation air intake passage 2105 through gaps below the heat dissipation air intake passage 2105 and the plurality of bottom side air inlets 21052.

As will be appreciated by those skilled in the art, since the heat dissipation air intake duct 2105 has both the plurality of front air inlets 21051 located at the front side thereof and the plurality of bottom air inlets 21052 located at the bottom side thereof, the air intake capability of the heat dissipation air intake duct 2105 is improved and the wind resistance is reduced. Not only avoiding the unsmooth air intake caused by the limitation of the area of the front side plate of the heat dissipation air intake channel 2105 when the heat dissipation air intake channel 2105 is only provided with a plurality of front air intakes 21051; it is also avoided that the heat dissipation air intake channel 2105 has only a plurality of bottom side air intake holes 21052, and impurities such as dust, flock and the like accumulate at the bottom side air intake holes 21052, so that the bottom side air intake holes 21052 are blocked, and further, the heat dissipation air intake channel 2105 cannot obtain enough air.

With continued reference to fig. 10 to 13, the heat dissipation air outlet channel 2106 includes a plurality of front air outlets 21061 formed on a front side plate of the housing 210, so that the hot air in the heat dissipation air inlet channel 2105 can flow out from the plurality of front air outlets 21061 to the outside. Optionally, the heat dissipation air outlet channel 2106 includes a plurality of bottom side air outlets (not shown) formed in a bottom plate thereof.

As shown in fig. 12, the housing 210 further includes a wind deflector 215 provided at the bottom side of the bottom plate of the press magazine 2103, the wind deflector 215 serving to prevent the bottom side air intake 21052 from sucking in the hot air blown out from the front air outlet 21061.

With continued reference to fig. 10-12, the bottom plate of the press bin 2103 is provided with a plurality of bin bottom air inlets 21031 on the windward side of the condenser 223, and the bottom plate of the press bin 2103 is provided with a plurality of bin bottom air outlets 21032 on the side of the heat dissipation fan 230 away from the condenser 223. And the plurality of bottom side air inlets 21052 and the plurality of bin bottom air inlets 21031 are positioned on one side of the wind deflector 215 and the plurality of bin bottom air outlets 21032 are positioned on the other side of the wind deflector 215. Based on this, it will be appreciated by those skilled in the art that ambient air can also enter the press cabin 2103 through the cabin bottom air inlet 21031, and that a portion of the hot air in the press cabin 2103 will flow from the cabin bottom air outlet 21032 to the ambient.

As can be seen in fig. 10-12, in some embodiments of the utility model, a portion of the plurality of bin bottom outlets 21032 is located below the compressor 221 and another portion of the plurality of bin bottom outlets 21032 is located on a front side of the compressor 221.

As shown in fig. 10 to 12, 14 and 15, a plurality of bin bottom outlets 21032 located at the front side of the compressor 221 are adjacent to the evaporating dish 250.

It will be appreciated by those skilled in the art that the air flow blocked by the rear side plate of the evaporating dish 250 can be reflected to the plurality of bin bottom outlets 21032 on the front side of the compressor 221, and further flows from the plurality of bin bottom outlets 21032 to the outside (as shown in fig. 14 and 15). This kind of structure is for the structure that evaporation pan 250 rear side does not have storehouse bottom air outlet 21032, can avoid evaporation pan 250 rear side board effectively to the shielding effect of air current, and then avoid the air current to appear the cyclone in evaporation pan 250 rear side board department effectively. Thus, in some embodiments of the present utility model, the blocking effect of the rear side plate of the evaporating dish 250 on the air flow, and the corresponding noise, can be effectively eliminated.

In other embodiments of the utility model, the plurality of bin bottom outlets 21032 may be arranged in any other feasible manner, as desired, such as, for example, arranging the plurality of bin bottom outlets 21032 on the front, right and bottom sides of the compressor 221, or on the front and/or right side of the compressor 221, by a person of ordinary skill in the art.

As shown in fig. 10 and 11, in some embodiments of the present utility model, the structure of the evaporation pan 250 in the horizontal direction is adapted to the structure of the heat dissipation air outlet channel 2106 in the horizontal direction, that is, the opposite sides of the evaporation pan 250 and the heat dissipation air outlet channel 2106 are parallel to each other, so that the evaporation pan 250 can spread the whole heat dissipation air outlet channel 2106 as much as possible, thereby increasing the evaporation area of the evaporation pan 250 and increasing the evaporation rate of water in the evaporation pan 250.

Optionally, the size of the evaporation pan 250 in the front-rear direction is larger than the size of the evaporation pan 250 in the left-right direction, so that the evaporation pan 250 has a sufficient length in the path of the air flow in the heat dissipation air outlet channel 2106, thereby increasing the contact time of the water in the evaporation pan 250 with the air flow and increasing the evaporation rate of the water in the evaporation pan 250.

Further, the width of the front portion of the evaporating dish 250 is gradually reduced from the rear to the front, and the width of the front portion of the heat dissipation air outlet channel 2106 is also gradually reduced from the rear to the front, so that the flow area of the front portion of the heat dissipation air outlet channel 2106 is gradually reduced, and thus the flow rate of the air flow at the front portion of the evaporating dish 250 is gradually increased, so as to ensure the evaporation rate of the water in the front portion of the evaporating dish 250.

As will be appreciated by those skilled in the art, in the heat dissipation air outlet channel 2106, the air flow just enters the evaporation pan 250, due to the higher temperature, has good heating effect on the water in the evaporation pan 250; but as the air flow gets closer to the front air outlet 21061, the air flow absorbs more and more heat from the water and the temperature gets lower, resulting in a poorer heating effect on the water. By gradually decreasing the width of the evaporation pan 250 and the front portion of the heat dissipation air outlet channel 2106 from back to front, the flow area of the front portion of the heat dissipation air outlet channel 2106 is gradually decreased, and thus the flow rate of the air flow therein is gradually increased, so that the air flow can overcome the influence of low temperature on the water evaporation efficiency at a high flow rate. Thus, in some embodiments of the present utility model, the evaporation efficiency of the air flow in the heat sink outlet channel 2106 to the water in the evaporation pan 250 is improved by gradually decreasing the width of the evaporation pan 250 and the front portion of the heat sink outlet channel 2106 from back to front.

Further, in the front-rear direction of the refrigeration module 200, the distance between the front surface of the evaporating dish 250 and the front side plate of the housing 210 is not less than 5mm, preferably not less than 15mm, to ensure a sufficient gap between the front surface of the evaporating dish 250 and the front side plate of the housing 210, reducing wind resistance thereto to the air flow.

As can be seen from fig. 12 to 14, the front air inlet 21051 and the front air outlet 21061 are each a bar-shaped hole extending in the up-down direction, and the top surface of the front end of the evaporating dish 250 is located at the middle upper portion of the bar-shaped hole in the vertical direction. That is, in the up-down direction of the refrigeration module 200, the tip of the front side plate of the evaporating dish 250 is located at the upper middle portion of the front air outlet 21061 to ensure that part of the air flow can be blown out from the front air outlet 21061 in the horizontal direction.

Further, in the up-down direction of the refrigeration module 200, the minimum distance between the top surface of the evaporation pan 250 (i.e., the top end of the front side plate of the evaporation pan 250) and the top wall of the heat dissipation air outlet channel 2106 is not less than 5mm, preferably not less than 15mm, so as to ensure that a sufficient gap exists between the front side plate of the evaporation pan 250 and the top wall of the heat dissipation air outlet channel 2106, and reduce the wind resistance to the air flow at the gap.

As shown in fig. 10, 11, 14 and 15, in some embodiments of the present utility model, a water receiving pipe 251 extending upward from the bottom plate of the evaporation pan 250 is provided in the evaporation pan 250. The lower end of the drain pipe 270 is inserted into the water receiving pipe 251 with a gap between the water receiving pipe 251 and the drain pipe 270 so that water flowing out of the drain pipe 270 can flow out of the water receiving pipe 251 from the gap and into the evaporation pan 250.

As will be appreciated by those skilled in the art, since the lower end of the drain pipe 270 is inserted into the water receiving pipe 251, a small amount of water will be stored in the water receiving pipe 251 after the defrosting of the evaporator 226 is completed to liquid-seal the bottom end of the drain pipe 270, i.e., the liquid surface in the water receiving pipe 251 is located above the bottom end of the drain pipe 270. As will be further appreciated by those skilled in the art, the bottom end of the drain pipe 270 is closed by water such that hot air within the evaporating dish 250 cannot enter the refrigerating compartment 2104 from the drain pipe 270, thereby improving the refrigerating efficiency of the refrigerating module 200.

In addition, in other embodiments of the present utility model, a sink may be provided in the evaporation pan 250 as required by those skilled in the art, and the lower end of the drain pipe 270 may be inserted into the sink. Specifically, the sink is formed on the bottom plate of the evaporation pan 250 and is recessed downward so that water can be secured in the sink even when the amount of water in the evaporation pan 250 is small, thereby ensuring that the drain pipe 270 can be water-sealed.

Thus far, the case module 100 and the refrigeration module 200 of the present utility model have been described in detail with reference to the accompanying drawings. Based on the foregoing, it can be understood by those skilled in the art that in the present utility model, by arranging the evaporator 226 to be inclined upward in the front-to-rear direction, the value of the included angle between the evaporator 226 and the horizontal plane is set to be 8 ° to 45 °, so that the evaporator 226 occupies a smaller space in the vertical direction and occupies a smaller space in the front-to-rear direction, so that the refrigerating room 2104 can reserve more space to arrange the air blower 240, and a sufficient gap is provided between the air blower 240 and the evaporator 226, thereby avoiding the excessive wind resistance and affecting the energy consumption of the refrigerating and freezing apparatus.

Further, by arranging the outer contours of the projections of the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 on the horizontal plane outside the projection of the refrigerating compartment 2104 on the horizontal plane and filling the heat insulation materials in the transverse gap 21071, the front gap 21072 and the longitudinal gap 21073 outside the refrigerating compartment 2104, the top plates of the press bin 2103, the heat dissipation air inlet channel 2105 and the heat dissipation air outlet channel 2106 are parallel to the bottom plate of the refrigerating compartment 2104, and the refrigerating compartment 2104 is ensured not to leak cold and the structure of the refrigerating module 200 is more compact.

Further, by disposing the evaporation pan 250 in the heat dissipation air outlet channel 2106, the evaporation pan 250 can heat the water in the evaporation pan 250 by utilizing the heat of the whole press bin 2103, thereby improving the evaporation rate of the water in the evaporation pan 250.

Further, by extending the drain pipe 270 from the top down into the evaporation pan 250, the defrost water in the refrigeration compartment 2104 can be quickly drained into the evaporation pan 250. By inserting the lower end of the drain pipe 270 into the water receiving pipe 251, a small amount of water is stored in the water receiving pipe 251 after the defrosting of the evaporator 226 is completed to liquid-seal the bottom end of the drain pipe 270. As will be appreciated by those skilled in the art, the bottom end of the drain pipe 270 is closed by water, so that hot air in the evaporating dish 250 cannot enter the refrigerating compartment 2104 from the drain pipe 270, thereby improving the refrigerating efficiency of the refrigerating module 200.

Meanwhile, the above-described structure of the refrigerating module 200 also makes the entire refrigerating module 200 flatter, leaving more space for the case module 100 thereon.

Thus far, the technical solution of the present utility model has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present utility model is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present utility model, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present utility model will fall within the protection scope of the present utility model.
