As shown in Figures 1 to 3, the refrigerator 100 generally includes an outer shell 110 and a storage liner arranged inside the outer shell 110. The space between the outer shell 110 and the storage liner is filled with heat-preserving material (forming foam Floor), the storage liner is limited with storage compartments.

Particularly, in this embodiment, the storage liner includes a frozen liner 130, two temperature-variable liners 140 arranged horizontally directly above the frozen liner 130, and a refrigerated liner 140 directly above the two temperature-variable liners 140 120. A freezing compartment 131 is defined in the freezing liner 130, a temperature changing chamber 141 is defined in each temperature-variable liner 140, and a refrigerator compartment 121 is defined in the refrigerating liner 120.

The temperature range in the freezer 131 is generally -22 ^° C to -14 ^° C. Changing chamber 141 can be freely adjusted to -18 ^° C to 8 ° C _o different types of optimal storage temperature of the article is not the same, a suitable storage location is not the same as, for example, fruit and vegetable foods suitable for storage in the refrigerator compartment 121, and Meat food is suitably stored in the freezer 131.

The front side of the freezing liner 130 is provided with two horizontally distributed freezing door bodies 132, the front side of each temperature-variable liner 140 is provided with a temperature-variable door body 142, and the front side of the refrigerating liner 120 is provided with two horizontally distributed refrigerators.

Used by the elderly. However, in this embodiment, since the cooling chamber 102 occupies the space below the freezer liner 130, the height of the freezing chamber 131 above the cooling chamber 102 is raised, and the degree of bending of the user when picking and placing items in the freezing chamber 131 is reduced. , Which can improve the user experience.

As shown in FIGS. 2 and 3, the refrigerator 100 further includes a freezing compartment air supply duct 133. The freezing compartment air supply duct 133 is formed with at least one first air supply outlet 133a communicating with the freezing compartment 131 and communicating with the cooling compartment 102 The first air supply inlet of the first evaporator 101 can deliver at least part of the air flow after the first evaporator 101 is cooled to the freezing compartment 131.

The freezer compartment air supply duct 133 can be arranged on the inner side of the rear wall of the freezer liner 130. For the foregoing embodiment in which the freezer compartment 131 is divided into two horizontally distributed freezing spaces, the freezer compartment air duct 133 has at least two For the aforementioned first air supply outlet 133a, at least one first air supply outlet 133a is in communication with one of the refrigerated spaces to blow cold air to the refrigerated space, and at least one other first air supply outlet 133a is in communication with another refrigerated space, In order to blow the cold air flow to the freezing space. As shown in Figure 3, there are four first air supply outlets 133a, and each refrigerated space corresponds to two first air supply outlets 133a.

The refrigerator 100 further includes a first blower 103 configured to cause at least part of the air flow cooled by the first evaporator 101 to flow into the freezer compartment 131 through the freezer compartment air duct 133. As shown in FIG. 3, the first blower 103 may be arranged behind the first evaporator 101. Specifically, the first blower 103 may be a centrifugal fan, a cross flow fan, or an axial flow fan. The first blower 103 shown in FIG. 3 It is an axial flow fan, and the first blower 103 is inclined forward to reduce the height space occupied by the first blower 103, thereby reducing the overall space occupied by the cooling chamber 102 and increasing the freezer compartment 131 above the cooling chamber 102 Storage volume. The refrigerator 100 also includes a cover (not numbered), which is buckled on the bottom wall of the freezer liner 130, and together with the bottom wall and two lateral side walls of the freezer liner 130, defines the aforementioned cooling chamber 102. An air outlet communicating with the air inlet of the freezer compartment air duct 133 is formed at the rear end.

The aforementioned vertical partition 134 includes a vertical plate section extending vertically upward from the upper surface of the cover, and the vertical plate section divides the freezing compartment 131 into two horizontally distributed freezing spaces. The vertical partition 134 may further include an upwardly extending vertical section located on the front side of the casing, and the vertical section and the vertical section are integrally formed to form the aforementioned vertical partition 134.

A first return air inlet 102a is formed on the front side of the cooling chamber 102, that is, a first return air inlet 102a is formed on the front wall of the housing, and the return air flow from the freezing chamber 131 enters the cooling chamber through the first return air inlet 102a. The chamber 102 is cooled by the first evaporator 101.

The first evaporator 101 can be placed horizontally in the cooling chamber 102 in the shape of a flat cube, that is, the long and wide surfaces of the first evaporator 101 are parallel to the horizontal plane, the thickness surface is perpendicular to the horizontal plane, and the thickness dimension is significantly smaller than that of the first evaporator. The length of the device 101. By placing the first evaporator 101 horizontally in the cooling chamber 102, the first evaporator 101 is prevented from occupying more space, and the storage volume of the freezing chamber 131 above the cooling chamber 102 is further ensured.

As shown in FIGS. 2 and 3, the refrigerator 100 also includes two variable-temperature greenhouse air supply ducts 143, and the two variable-temperature greenhouse air-supply ducts 143 correspond to the two variable-temperature inner tanks 140, and each have a corresponding variable-temperature interior The second air supply outlet (not numbered) connected to the bladder 140 and the second air supply inlet (not numbered) connected to the top of the freezer compartment air supply duct 133 to convey part of the air flow in the freezer compartment air supply duct 133 To the corresponding changing room 141.

In particular, as shown in FIG. 2, two variable temperature air doors 144 for connecting the two variable temperature greenhouse air supply ducts 143 to the freezer compartment air supply duct 133 are laterally distributed at the top of the freezer compartment air supply duct 133 It is understandable that the two temperature-variable air doors 144 should be respectively arranged at the second air supply inlets of the air supply ducts 143 of the two temperature-changing greenhouses, and are configured to be able to open or close the corresponding second air supply inlets in a controlled manner to Connect or disconnect the corresponding air supply duct 143 of the temperature-changing greenhouse and the air supply duct 133 of the freezer compartment. In other words, the two air supply air ducts 143 of the variable-temperature greenhouse can be controllably communicated with the air supply air duct 133 of the freezer compartment through the two variable-temperature air doors 144 to adjust the amount of cold entering the variable-temperature greenhouse 141.

As shown in Figures 2 and 3, two air supply ducts 143 for the temperature-variable greenhouse can be arranged in the foam layer on the rear side of the corresponding temperature-variable liner 140. Correspondingly, the rear wall of each temperature-variable liner 140 is formed with The corresponding air inlet 140a of the second air outlet of the air supply duct 143 of the variable greenhouse is connected to the air inlet 140a.

In the traditional refrigerator 100 with variable greenhouse, the variable greenhouse air duct with variable temperature damper is installed On the inner side of the rear wall of the variable greenhouse, since the height of the variable greenhouse is generally small, the operating space is relatively narrow, and the installation of the air supply duct of the variable greenhouse is difficult, resulting in poor sealing consistency. However, in this embodiment, the air supply duct 143 for the temperature-variable greenhouse equipped with the temperature-variable air door 144 is provided in the foam layer at the rear of the temperature-variable inner liner 140, and the interior of the temperature-variable liner 140 does not need to be separately provided with air ducts and other structures. , Convenient operation and high reliability.

As shown in Figures 2 and 3, the refrigerator 100 further includes two variable temperature return air ducts 145, corresponding to the two variable temperature inner tanks 140, which are arranged in the foam layers on both lateral sides of the refrigerator 100, and respectively have The inlet end communicating with the corresponding temperature changing chamber 141 and the outlet end communicating with the cooling chamber 102 are used to convey the return air flow in the corresponding temperature changing chamber 141 to the cooling chamber 102, which is cooled by the first evaporator 101. An air circulation is formed between the greenhouse 141 and the cooling chamber 102.

The laterally right side wall of the variable temperature liner 140 located on the lateral right side is formed with a side return air outlet communicating with the inlet end of the variable greenhouse return air duct 145 located on the lateral right side, and the side return air outlet may be adjacent to the temperature variable door on the right side Correspondingly, the inlet end of the return air duct 145 of the temperature-changing greenhouse located on the right side is adjacent to the temperature-changing door body 142.

Correspondingly, the lateral right side wall of the cooling chamber 102 (that is, the area corresponding to the lateral right side wall of the freezing liner 130 and the cooling chamber 102) is formed to communicate with the outlet end of the return air duct 145 located on the right side of the variable greenhouse The side return air inlet may be adjacent to the freezer door body 132 on the right side, and accordingly, the outlet end of the return air duct 145 of the right variable greenhouse is adjacent to the freezer door body 132 on the right side.

The horizontal left side wall of the variable temperature liner 140 located on the horizontal left side is formed with a side return air outlet communicating with the inlet end of the variable greenhouse return air duct 145 located on the horizontal left side, and the side return air outlet may be adjacent to the left temperature variable door Correspondingly, the inlet end of the return air duct 145 of the temperature-changing greenhouse located on the left side is adjacent to the temperature-changing door body 142 on the left side.

Correspondingly, the lateral left side wall of the cooling chamber 102 (that is, the area corresponding to the lateral left side wall of the refrigerating liner 130 and the cooling chamber 102) is formed with a side return communicating with the outlet end of the return air duct 145 of the variable greenhouse The air inlet, the side return air inlet may be adjacent to the freezer door body 132 on the right, and correspondingly, the outlet end of the return air duct 145 of the left variable greenhouse is adjacent to the freezer door body 132 on the left.

In the traditional refrigerator 100, the air supply inlet and the return air outlet of the variable temperature chamber are generally located at the rear of the variable temperature inner liner. The distance between the two is relatively close. Under the action of wind pressure, part of the cold air is not used, that is, the cold air inside the freezer is not cooled. In the case of storing items, they are directly sucked back into the return air duct of the variable greenhouse by the return air outlet, causing loss of air volume in the refrigeration system. In this embodiment, the return air duct 145 of the temperature-variable greenhouse is provided in the foam layer outside the lateral side wall of the temperature-variable liner 140, and the side return air outlet is located at the position of the lateral side wall of the temperature-variable liner 140 near the temperature-variable door body 142 , Because the air inlet 140a of the variable greenhouse 141 is located at the rear, side The return air outlet is located at the front. After the supply air in the variable room 141 is blown out from the rear, all the items stored in the variable room 141 can enter the cooling room 102 through the variable room return air duct 145, thereby improving the cold air Utilization rate, reduce cooling loss.

The refrigerator 100 further includes a refrigerating compartment air supply duct 123, which is arranged on the inner side of the rear wall of the refrigerating liner 120, and at least one third air supply outlet 123a communicating with the refrigerating compartment 121 is formed.

In some embodiments, as shown in FIG. 2 and FIG. 3, the refrigerating compartment 121 may have an independent second evaporator 124 and a second blower 125, and the second evaporator 124 and the second blower 125 are arranged in the refrigerating compartment to supply air. In the duct 123, the second blower 125 is configured to promote the air flow cooled by the second evaporator 124 to flow into the refrigerating compartment 121 through the refrigerating compartment air duct 123. Thus, the refrigerator 100 with a dual refrigeration system is constructed to ensure the uniformity of the temperature in the refrigerating compartment 121, and to prevent the freezer compartment 131 (or the greenhouse 141) and the refrigerating compartment 121 from smelling.

As shown in FIG. 3, the second blower 125 is arranged above the second evaporator 124, a second return air inlet (not numbered) is formed at the lower end of the air duct 123 of the refrigerating compartment, and the third air outlet 123a is located at the second Above the return air inlet, the return air flow from the refrigerating compartment 121 flows back to the second evaporator 124 through the second return air inlet and is cooled therefrom, thereby forming an air circulation between the refrigerating compartment 121 and the second evaporator 124.

The second evaporator 124 can be vertically arranged in the air supply duct 123 of the refrigerating compartment, and the front and rear dimensions of the second evaporator 124 are significantly smaller than its lateral dimensions, thereby reducing the front and rear space occupied by the second evaporator 124 and ensuring The storage volume of the refrigerator compartment 121.

In an alternative embodiment, the refrigerating compartment air duct 123 can be controlled to be connected or disconnected through the refrigerating air door and the freezing compartment air duct 133, thereby forming a refrigerator 100 with a single refrigeration system. Of course, in other alternative embodiments, the inside of the freezing liner 130 can be directly cooled by a refrigerating evaporator to form a hybrid refrigerating refrigerator 100 combining air cooling and direct cooling.

A compressor compartment is defined at the lower rear of the refrigerator 100. In particular, the compressor compartment may be located at the lower rear of the cooling chamber 102.

In the conventional refrigerator 100, the compressor compartment is located behind the lowermost freezer compartment 131, and the freezer compartment 131 inevitably becomes a special-shaped space for the compressor compartment, which increases the reduction of the storage volume of the freezer compartment 131. However, in this embodiment, since the cooling chamber 102 occupies the space below the refrigerating liner 130, the cooling chamber 102 can provide a place for the compressor compartment, and the freezer compartment 131 does not need to make way for the compressor compartment, so that the freezer compartment 131 becomes A regular rectangular space increases the storage volume of the freezer compartment 131, and at the same time facilitates the placement of large and difficult-to-divide items, and solves the problem of not being able to place the freezer compartment 131 at the bottom. Pain points of placing larger items inside.

More specifically, as shown in FIG. 4, a compressor 104, a radiator fan 106, and a condenser 105 are arranged in the compressor cabin, which are sequentially spaced along the transverse direction. The bottom wall of the refrigerator 100 defines a horizontally arranged bottom air inlet 110a corresponding to the condenser 105 and a bottom air outlet 110b corresponding to the compressor 104. The heat dissipation fan 106 is configured to draw in ambient air from the surrounding environment of the bottom air inlet 110a and The air is forced to pass through the condenser 105 first, and then through the compressor 104, and then flow from the bottom air outlet 110b to the surrounding environment, thereby dissipating heat from the condenser 105 and the compressor 104.

The existing refrigerator 100 generally forms a heat dissipation circulating air path in the front and rear directions. However, for the built-in refrigerator 100, the reserved space between the back of the refrigerator 100 and the cabinet is small, the front and rear airflow is not smooth, and the heat dissipation efficiency is low. In order to ensure smooth front and rear airflow, it is necessary to increase the reserved space of the built-in refrigerator 100 and the cabinet, which brings about the problem of increased space occupied by the refrigerator 100.

In this embodiment, by defining the bottom wall of the refrigerator 100 with a bottom air inlet 110a and a bottom air outlet 110b arranged horizontally, the heat dissipation airflow circulates at the bottom of the refrigerator 100, making full use of the gap between the refrigerator 100 and the supporting surface. One space, there is no need to increase the distance between the rear wall of the refrigerator 100 and the cabinet, which reduces the space occupied by the refrigerator 100 while ensuring good heat dissipation in the compressor cabin.

As shown in FIG. 4, the bottom wall of the refrigerator 100 is defined by a bottom horizontal section 113 on the front side and a pallet 112 on the rear side. The pallet 112 and the bottom horizontal section 113 are spaced apart to utilize the pallet 112. The space between the front end of the bottom horizontal section 113 and the rear end of the bottom horizontal section 113 forms a bottom opening communicating with the external space. The compressor 104, the radiating fan 106 and the condenser 105 are all arranged on the supporting plate 112.

A partition 117 is also provided at the bottom opening, and the partition 117 is configured to divide the bottom opening into the aforementioned horizontally distributed bottom air inlet 110a and bottom air outlet 110b. As a result, trough-shaped bottom air inlets 110a and bottom air outlets 110b with larger opening sizes are formed, which increases the air inlet and outlet areas, reduces the air inlet resistance, makes the air flow smoother, and the manufacturing process is simpler , Make the overall stability of the compressor cabin stronger.

In particular, the refrigerator 100 further includes a windshield 107 extending forward and backward. The windshield 107 is located between the bottom air inlet 110a and the bottom air outlet 110b, and extends from the lower surface of the bottom horizontal section 113 to the lower surface of the pallet 112, and The lower end of the partition 117 is connected to completely isolate the bottom air inlet 110a and the bottom air outlet 110b by the windshield 107 and the partition 117, so that when the refrigerator 100 is placed on a supporting surface, the bottom wall of the refrigerator 100 and the support The space between the surfaces allows the outside air to enter the compressor cabin through the bottom air inlet 110a on the lateral side of the windshield 107 under the action of the heat dissipation fan 106, and then flow through the condenser 105, the compressor 104, and finally from the The other side of the windshield 107 transversely The bottom air outlet 110b flows out, thereby completely isolating the bottom air inlet 110a and the bottom air outlet 110b, ensuring that the outside air entering the condenser 105 and the hot air discharged from the compressor 104 will not flow together, improving the heat dissipation effect.

So far, those skilled in the art should realize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, they can still be disclosed according to the present invention without departing from the spirit and scope of the present invention. The content directly determines or deduces many other variations or modifications that conform to the principles of the present invention.
