Therefore, the occupied space of the cooling chamber is reduced from two aspects, and the storage volume of the storage compartment above the cooling chamber is increased.
In addition, the distance between the air supply fan and the evaporator is relatively increased, so that the degree of frosting of blades can be reduced; the distance between the air supply fan and a water outlet is also relatively increased, the volume of hot air sucked by the air supply fan from the water outlet can be reduced, and therefore the influence of the hot air on temperature rise of the storage compartment is reduced. Moreover, since the size of the evaporator in the front-back direction is increased, the coverage of the water outlet is increased, the hot air entering from the water outlet can be cooled by the evaporator, and the temperature of the storage compartment is prevented from rising.
Further, according to the refrigerator, by improving the structure of the air supply duct and improving the position of the air supply fan, the problem of frosting of the blades of the air supply fan can be completely avoided, and therefore refrigerating performance of the refrigerator is improved.
Furthermore, in the refrigerator, the bottom air inlet and the bottom air outlet which are distributed in a lateral direction are defined in the bottom wall of the refrigerator, heat dissipating airflow completes circulation at the bottom of the refrigerator, and the space between the refrigerator and the supporting surface is fully utilized, so that the distance between the rear wall of the refrigerator and a cupboard does not need to be increased, and good heat dissipation of the compressor chamber is ensured while the occupied space of the refrigerator is reduced.
Still further, in the refrigerator, the bottom air inlet and the bottom air outlet are completely isolated through the wind blocking strip and the divider, which guarantees that no cross flow of the external air entering the condenser and the hot air exhausted from the compressor exists, thus improving the heat dissipation effect, and guaranteeing normal operation of a refrigerating system of the refrigerator.
According to the following detailed descriptions of specific embodiments of the present invention in conjunction with the drawings, those skilled in the art will more clearly understand the above and other objectives, advantages and features of the present invention.
Some specific embodiments of the present invention are described in detail below with reference to the drawings by way of example and not limitation.

The present embodiment provides a refrigerator 100, which is described below with reference to
Referring to
As can be appreciated by those skilled in the art, the cabinet further defines a cooling chamber 136 and a compressor chamber, and the refrigerator 100 may further include an evaporator 101, an air supply fan 103, a compressor 104, a condenser 105, a throttling element (not shown) and the like. The evaporator 101 is disposed in the cooling chamber 136. The compressor 104 and the condenser 105 are disposed in the compressor chamber. The evaporator 101 is connected with the compressor 104, the condenser 105 and the throttling element through a refrigerant pipeline to form a refrigeration circulation loop, so as to cool down upon starting of the compressor 104 to cool air flowing therethrough. The shell 110 and each liner (explained in further detail below) are thermally insulated through the foamed layer, and correspondingly, the compressor chamber and the cooling chamber 136 are also thermally insulated through the foamed layer.
Particularly, referring to
In some embodiments, the air supply fan 103 is vertically disposed at the lower end of the air supply duct 134 and configured to promote at least part of airflow cooled by the evaporator 101 to be conveyed into the storage compartment 131 through the air supply duct 134.
The lowermost storage liner 130 is a freezing liner, and the storage compartment 131 defined by the storage liner 130 is a freezing chamber. The freezing chamber has the lowest temperature relative to a variable-temperature chamber and a refrigerating chamber, and the cooling chamber 136 is distributed under the freezing chamber, which is beneficial to maintain the lowest temperature of the freezing chamber. A freezing chamber door body 132 is disposed on the front side of the freezing liner to open and close the storage freezing chamber.
In previous patents applied by applicants of the present invention, the air supply fan 103 is positioned in the cooling chamber 136 and behind the evaporator 101. The air supply fan 103 has a certain height, which causes that the height of the upper wall of the cooling chamber 136 is relatively high, and the height space occupied by the cooling chamber 136 is increased. Also, the air supply fan 103 is positioned behind the evaporator 101, and some space is occupied in the front-back direction, which causes that the size of the evaporator 101 in the front-back direction is limited, and only the height of the evaporator 101 can be increased in the height direction to ensure reasonable heat exchange area of the evaporator 101, which further causes that the upper wall of the cooling chamber 136 is higher, the larger space is occupied, and the volume of the storage compartment 131 above the cooling chamber 136 is reduced.
Based on the problems above, in the refrigerator 100 provided by the present embodiment, the position of the air supply fan 103 is adjusted to the lower end of the air supply duct 134, and the air supply fan is vertically disposed behind the evaporator 101. That is, the air supply fan 103 does not occupy the space of the cooling chamber 136 anymore, but moves to a higher position behind the evaporator 101, so that the size of the evaporator 101 in the front-back direction can be increased, and the size of the evaporator in the height direction can be decreased, and the height of the top wall of the cooling chamber 136 does not need to be increased due to the height of the air supply fan 103. Therefore, the height of the cooling chamber 136 is reduced from two aspects, and the storage volume of the storage compartment 131 above the cooling chamber 136 is increased.
In some embodiments, referring to
An air duct inlet (not numbered) in communication with the cooling chamber 136 is formed in the front wall face of the lower end of the air supply duct 134, and under the driving of the air supply fan 103, airflow cooled by the evaporator 101 in the cooling chamber 136 flows into the air supply duct 134 and is blown into the storage compartment 131 through the air supply duct 134. The air supply duct 134 is provided with at least one first air outlet 134a in communication with the storage compartment 131.
In addition, compared with a traditional refrigerator 100 in which the cooling chamber 136 is positioned behind the storage compartment 131, the refrigerator 100 of the present embodiment has the advantages that the cooling chamber 136 does not occupy the space behind the storage compartment 131 anymore, the depth of the storage compartment 131 is increased, and the storage volume of the storage compartment 131 is further increased. Moreover, due to the existence of the cooling chamber 136, the height of the storage compartment 131 thereabove is increased, the bend degree of a user when taking articles from the storage compartment 131 or placing thereto is reduced, the user experience is improved, and the refrigerator is particularly convenient for the elderly to use.
In some more specific embodiments, the refrigerator 100 includes a lowermost storage liner 130, a housing 135, an evaporator 101, and at least one air supply fan 103. The housing 135 is disposed within a space defined by the storage liner 130 and configured to divide the space into a cooling chamber 136 positioned below and a storage compartment 131 positioned above the cooling chamber 136. The evaporator 101 is disposed in the cooling chamber 136 and configured to cool air flowing through the evaporator so as to form cooling air supplied to the storage compartment 131, and the air supply fan 103 is configured to promote the air to circularly flow between the cooling chamber 136 and the storage compartment 131, so that the cooling air can be continuously supplied to the storage compartment 131, to ensure that the temperature of the storage compartment 131 can reach a corresponding target temperature. Specifically, in some embodiments, the housing 135 covers the bottom wall of the storage liner 130, and defines the cooling chamber 136 together with the bottom wall and two lateral side walls of the storage liner 130, an airflow outlet (not numbered) of the cooling chamber in communication with the air duct inlet of the air supply duct 134 is formed in the rear end of the housing 135, a front return air inlet 135a is formed in the front wall of the housing 135, and return airflow of the storage compartment 131 enters the cooling chamber 136 through the front return air inlet 135a and is cooled by the evaporator 101.
In the traditional refrigerator, the lowermost space of the refrigerator is generally a storage space, the position of the storage space is relatively low, and the user needs to bend down or squat greatly to take the articles from the lowermost storage space or place thereto, which causes the traditional refrigerator is inconvenient to use, especially for the elderly. Also, the evaporator of the traditional refrigerator is generally positioned behind the lowermost storage space and occupies the area behind the lowermost storage space, so that the depth of the lowermost storage space is reduced. Moreover, the compressor chamber of the traditional refrigerator is generally positioned on the lower rear side of the lowermost storage space, and the lowermost storage space inevitably needs to give way to the compressor chamber, which causes that the lowermost storage space is special-shaped, the volume of the lowermost storage space is further reduced, and the storage space is inconvenient to store the articles which are large in size and not easy to divide.
In order to solve various problems of the traditional refrigerator, prior to the present application, applicants of the present invention designed a novel refrigerator with an evaporator at the bottom. The common point of the novel refrigerator and the refrigerator 100 of the present embodiment is that the cooling chamber 136 is defined by the lowermost storage liner 130, and the storage compartment 131 defined by the storage liner 130 is positioned above the cooling chamber 136. According to the refrigerator 100 with such design, due to the fact that the lowest space of the refrigerator 100 is the cooling chamber 136, the height of the storage compartment 131 above the cooling chamber 136 is raised, the bend degree of the user when taking the articles from the storage compartment 131 or placing thereto is reduced, and the user experience is improved. In addition, the evaporator 101 does not occupy the rear space of the storage compartment 131 anymore, and the depth of the storage compartment 131 is guaranteed.
Also, the compressor chamber can be positioned on the lower rear side of the cooling chamber 136, the cooling chamber 136 gives way to the compressor chamber, and the storage compartment 131 does not need to give way to the compressor chamber, so that a rectangular space with large volume and regular shape can be formed, and is convenient to accommodate the articles which are large in size and not easy to divide, and the problem that the large articles cannot be placed in the storage compartment 131 is solved.
However, in the novel evaporator, the air supply fan 103 is positioned in the cooling chamber 136 and behind the evaporator 101. The air supply fan 103 has a certain height, which causes that the height of the upper wall of the cooling chamber 136 is relatively high, and the height space occupied by the cooling chamber 136 is increased. Also, the air supply fan 103 is positioned behind the evaporator 101, and occupies some space in the front-back direction, which causes that the size of the evaporator 101 in the front-back direction is limited, and only the height of the evaporator 101 can be increased in the height direction to ensure reasonable heat exchange area of the evaporator 101, which further causes that the upper wall of the cooling chamber 136 is higher, the larger space is occupied, and the volume of the storage compartment 131 above the cooling chamber 136 is reduced. In addition, if there is a gap between the housing 135 and the evaporator 101, return air of the storage compartment 131 will pass through the gap to enter the air supply fan 103, which causes frosting of blades of the air supply fan 103 and reduction of rotational speed of the air supply fan 103, reduces air volume, and adversely affects refrigeration performance. Moreover, since the air supply fan 103 is close to a water outlet 130b (the water outlet 130b for discharging water from frost of the evaporator 101 is formed in the bottom wall of the storage liner 130), hot air outside the refrigerator enters the cooling chamber 136 through the water outlet 130b, and is easy to be directly sucked by the air supply fan 103 without being cooled by the evaporator 101, and be sent to the storage compartment 131, resulting in that the temperature of the storage compartment 131 rises, and adverse effects are brought to the fresh-keeping quality of food materials.
In order to solve the problems above, the applicants of the present application make modifications on the setting position of the air supply fan 103. The air supply fan 103 is disposed in the air supply duct 134, so that the air supply fan 103 does not occupy the space of the cooling chamber 136 anymore, the size of the evaporator 101 in the front-back direction can be increased, the size of the evaporator in the height direction can be reduced, the height of the cooling chamber 136 is prevented from being affected by the height of the evaporator 101, and the size of the cooling chamber 136 in the vertical direction does not need to be increased for accommodating the air supply fan 103. Therefore, the occupied space of the cooling chamber 136 is reduced from two aspects, and the storage volume of the storage compartment 131 above the cooling chamber 136 is increased. In addition, the distance between the air supply fan 103 and the evaporator 101 is relatively increased, so that the degree of frosting of the blades can be reduced; the distance between the air supply fan 103 and the water outlet 130b is also relatively increased, the volume of the hot air sucked by the air supply fan 103 from the water outlet 130b can be reduced, and therefore the influence of the hot air on temperature rise of the storage compartment is reduced. Moreover, since the size of the evaporator 101 in the front-back direction is increased, the coverage of the water outlet 130b is increased, the hot air entering from the water outlet 130b can be cooled by the evaporator 101, and the temperature of the storage compartment 131 is prevented from rising.
In some embodiments, as shown in
In some embodiments, a vertical partition plate 137 may be disposed in the space defined by the storage liner 130, and divides the space defined by the storage liner 130 into two storage compartments 131 that are distributed in the lateral direction. At least one air supply fan 103 is disposed in the section of the air supply duct 134 corresponding to one storage compartment 131, and at least one another air supply fan 103 is disposed in the section of the air supply duct 134 corresponding to the other storage compartment 131, so that a relative large air supply volume of the two storage compartments 131 is guaranteed. For example, as shown in
In some embodiments, the air supply duct 134 may be disposed on the front side of the rear wall of the storage liner 130, at least one first air outlet 134a for blowing the cooling air to the storage compartment 131 is formed in the front wall of the air supply duct, and the at least one air supply fan 103 is disposed at the lower end of the air supply duct 134. In the present embodiment, since the air supply fan 103 is positioned at the lower end of the air supply duct 134, the thickness of the air supply duct 134 is increased only at the position where the air supply fan 103 is arranged, so that the depth of the storage compartment 131 can be guaranteed. There may be a plurality of first air outlets 134a, as shown in
In some embodiments, the refrigerator 100 further includes a refrigerating liner 120 and two variable-temperature liners 140, the two variable-temperature liners 140 being distributed right above the storage liner 130 in the lateral direction, and the refrigerating liner 120 being positioned right above the two variable-temperature liners 140.
A variable-temperature chamber 141 is defined in each variable-temperature liner 140, and a variable-temperature chamber door body 142 is disposed on the front side of each variable-temperature liner 140 to open and close the corresponding variable-temperature chamber 141. A refrigerating chamber door body 122 is disposed on the front side of the refrigerating liner 120 to open and close the refrigerating chamber 121. In some embodiments, the refrigerator 100 further includes two variable-temperature chamber air supply ducts (not shown) and two variable-temperature chamber air return ducts (not shown) in one-to-one correspondence with the two variable-temperature liners 140. The variable-temperature chamber air supply ducts can be in controllable communication with the air supply duct 134 through variable-temperature chamber air doors, and the variable-temperature chamber return air ducts are provided with inlets in communication with the variable-temperature liners 140 and outlets in communication with the cooling chamber 136, so that return airflow of the variable-temperature chambers 141 can be conveyed into the cooling chamber 136.
The variable-temperature chamber air supply ducts and the variable-temperature chamber return air ducts can be disposed according to the number of the variable-temperature liners 140, for example, there may be one or more variable-temperature chamber air supply ducts and variable-temperature chamber return air ducts.
In some embodiments, as shown in
In some embodiments, a containing groove 130a protruding rearwards may be formed at the lower end of the rear wall of the storage liner 130, and the air supply fan 103 is disposed in the containing groove 130a, so that the space occupied by the air supply fan 103 is reduced and the volume of the storage compartment 131 is increased.

Therefore, the applicants of the present invention break the conventional design idea and creatively propose a new scheme different from the conventional design. According to the present embodiment, a heat dissipation structure of the refrigerator 100 is improved, so that the heat dissipation effect of the compressor chamber can be greatly improved, and meanwhile, the occupied space of the refrigerator 100 is reduced. Specifically, a bottom air inlet 110a close to the condenser and a bottom air outlet 110b close to the compressor 104 which are distributed in a lateral direction are defined in the bottom wall of the refrigerator 100. The refrigerator 100 completes circulation of the heat dissipation airflow at the bottom, the space between the refrigerator 100 and a supporting surface is fully utilized, the ventilation space behind the refrigerator 100 does not need to be enlarged, the occupied space of the refrigerator 100 is reduced, and meanwhile, good heat dissipation of the compressor chamber is guaranteed, so that the problem that heat dissipation of the compressor chamber and space occupation of the embedded refrigerator 100 cannot be balanced is fundamentally solved, which is of particularly important significance.
The heat dissipation fan 106 is configured to suck ambient air from the ambient environment of the bottom air inlet 110a and promote the air to first flow through the condenser 105, then flow through the compressor 104, and finally flow to the ambient environment through the bottom air outlet 110b, so that heat from the condenser 105 and the compressor 104 is dissipated.
In a vapor compression refrigeration cycle, the surface temperature of the condenser 105 is generally lower than that of the compressor 104, so the external air is made to cool the condenser 105 first and then cool the compressor 104 in the process above.
In addition, for the problem of improving the heat dissipation effect of the compressor chamber, those skilled in the art generally increase the number of rear air inlets and rear air outlets 1162a in the rear wall of the compressor chamber to increase the ventilation area, or increase the heat exchange area of the condenser 105, for example, using a U-shaped condenser with a larger heat exchange area.
The applicants of the present invention creatively recognized that the heat exchange area of the condenser 105 and the ventilation area of the compressor chamber are not as larger as better, and in a conventional design scheme for increasing the heat exchange area of the condenser 105 and the ventilation area of the compressor chamber, the problem of non-uniform heat dissipation of the condenser 105 is caused, and adverse effects are generated on a refrigerating system of the refrigerator 100.
Therefore, the applicants of the present invention break the conventional design idea to further improve the heat dissipation structure of the compressor chamber. At least one rear air outlet 1162a is formed in a plate section 1162 of the rear wall of the compressor chamber corresponding to the compressor 104. A plate section 1161 of a back plate 116 (the rear wall of the compressor chamber) facing the condenser 105 is a continuous plate surface. That is, the plate section 1161 of the back plate 116 facing the condenser 105 is not provided with heat dissipation holes, so that the heat dissipation airflow entering the compressor chamber can be sealed at the condenser 105, thus more ambient air entering from the bottom air inlet 110a is concentrated at the condenser 105, heat exchange uniformity of all condensation sections of the condenser 105 is guaranteed, a better heat dissipation airflow path is favorably formed, and the better heat dissipation effect can also be achieved. The applicants of the present invention creatively recognized that even on the premise that the heat exchange area of the condenser 105 is not increased, a better heat dissipation airflow path can be formed by reducing the ventilation area of the compressor chamber uncharacteristically, and a better heat dissipation effect can still be achieved.
Moreover, since the plate section 1161 of the back plate 116 facing the condenser 105 is the continuous plate surface and is not provided with the air inlet, it is avoided that in conventional design, air exhaust and air feeding are both concentrated at the rear part of the compressor chamber, which causes that the hot air blown from the compressor chamber is not cooled by the ambient air in time and enters the compressor chamber again, causing adverse effects on heat exchange of the condenser 105, and thus the heat exchange efficiency of the condenser 105 is improved.
Furthermore particularly, the condenser 105 may include a first straight section 1051 extending transversely, a second straight section 1052 extending forwards and rearwards, and a transition curved section (not numbered) connecting the first straight section 1051 and the second straight section 1052, and thus the L-shaped condenser 105 with an appropriate heat exchange area is formed. The plate section 1161 of the rear wall (back plate 116) of the compressor chamber corresponding to the condenser 105 is also the plate section 1161 of the back plate 116 facing the first straight section 1051.
In some embodiments, a side ventilation hole 119a can be formed in each of two lateral side walls of the compressor chamber. The side ventilation hole 119a can be covered with a ventilation cover plate 108. The ventilation cover plate 108 is provided with grille-type ventilation ports. The shell of the refrigerator 100 includes two lateral cabinet side plates 111. The two cabinet side plates 111 vertically extend to form two side walls of the refrigerator 100, and a side opening 1111a in communication with the corresponding side ventilation hole 119a is formed in each of the two cabinet side plates 111, so that the heat dissipation airflow flows to the outside of the refrigerator 100, the heat dissipation path is increased, and the heat dissipation effect of the compressor chamber is guaranteed. The ambient airflow entering from the side ventilation holes 119a directly exchanges heat with the second straight section 1052, and the ambient air entering from the bottom air inlet 110a directly exchanges heat with the first straight section 1051, so that more ambient air entering the compressor chamber is further concentrated at the condenser 105, and the overall heat dissipation uniformity of the condenser 105 is guaranteed.

The bottom plate may include a bottom horizontal section 113 positioned on the front side of the bottom and a bent section bending and extending upwards and rearwards from the rear end of the bottom horizontal section 113. The bent section extends to the upper side of the supporting plate 112. The compressor 104, the heat dissipation fan 106 and the condenser 105 are sequentially arranged on the supporting plate 112 at intervals in the lateral direction, and are positioned in a space defined by the supporting plate 112, the two side plates, the back plate 116 and the bent section.
The supporting plate 112 and the bottom horizontal section 113 jointly form a bottom wall of the refrigerator 100. The supporting plate 112 and the bottom horizontal section 113 are spaced apart to define a bottom opening by the rear end of the bottom horizontal section 113 and the front end of the supporting plate 112. The bent section has an inclined section 114 positioned above the bottom air inlet 110a and the bottom air outlet 110b. The two side plates extend upwards from two lateral sides of the supporting plate 112 to two lateral sides of the bent section respectively so as to seal two lateral sides of the compressor chamber. The back plate 116 extends upwards from the rear end of the supporting plate 112 to the rear end of the bent section.
Specifically, the bent section may include a vertical section 1131, the aforementioned inclined section 114 and a top horizontal section 115. The vertical section 1131 extends upwards from the rear end of the bottom horizontal section 113. The inclined section 114 extends upwards and rearwards from the upper end of the vertical section 1131 to the upper side of the supporting plate 112. The top horizontal section 115 extends rearwards from the rear end of the inclined section 114 to the back plate, so as to cover the upper sides of the compressor 104, the heat dissipation fan 106 and the condenser 105.
The refrigerator 100 further includes a divider 117 disposed behind the bent section. The front part of the divider is connected with the rear end of the bottom horizontal section 113, and the rear part of the divider is connected with the front end of the supporting plate 112. The divider is configured to divide the bottom opening into the bottom air inlet 110a and the bottom air outlet 110b which are distributed in a lateral direction.
It can be known from the foregoing that the bottom air inlet 110a and the bottom air outlet 110b of the present embodiment are defined by the divider 117, the supporting plate 112 and the bottom horizontal section 113, so that the groove-shaped bottom air inlet 110a and the groove-shaped bottom air outlet 110b with large opening sizes are formed, the air feeding area and the air exhaust area are increased, the air feeding resistance is reduced, making the circulation of airflow smoother, the manufacturing process is simpler, and the integral stability of the compressor chamber is stronger.
In particular, the applicants of the present invention creatively realized that a slope structure of the inclined section 114 is capable of guiding and rectifying feeding airflow, so that the airflow entering from the bottom air inlet 110a flows more concentratedly to the condenser 105, avoiding that the airflow is too dispersed to pass more through the condenser 105, thereby further ensuring the heat dissipation effect of the condenser 105. Meanwhile, the slope of the inclined section 114 guides exhausting airflow from the bottom air outlet 110b to the front side of the bottom air outlet, so that the exhausting airflow flows out of the compressor chamber more smoothly, and thus the smoothness of airflow circulation is further improved.
Furthermore particularly, in a preferred embodiment, the inclined section 114 has an included angle of less than 45 degrees with the horizontal plane, and in such embodiment, the inclined section 114 is better in airflow guiding and rectifying effect.
Moreover, it is unexpected that the applicants of the present application creatively recognized that the slope of the inclined section 114 provides a better dampening effect on airflow noise, and in prototype tests, noise of the compressor chamber with the aforementioned specially designed inclined section 114 can be reduced by 0.65 decibels or above.
In addition, in the traditional refrigerator 100, the refrigerator 100 is generally provided with a bearing plate of a roughly-flat plate type structure at the bottom, and the compressor 104 is disposed on the inner side of the bearing plate, so vibration generated during operation of the compressor 104 has a large influence on the bottom of the refrigerator 100. In the present embodiment, as previously described, the bottom of the refrigerator 100 is constructed into a solid structure by the specially constructed bottom plate and supporting plate 112, an independent solid space is provided for arrangement of the compressor 104, and the supporting plate 112 is utilized to carry the compressor 104, so that the influence of vibration of the compressor 104 on other components at the bottom of the refrigerator 100 is reduced. In addition, by designing the refrigerator 100 to be of the above ingenious special structure, the bottom of the refrigerator 100 is compact in structure and reasonable in layout, the overall volume of the refrigerator 100 is reduced, meanwhile, the space of the bottom of the refrigerator 100 is fully utilized, and thus the heat dissipation efficiency of the compressor 104 and the condenser 105 is guaranteed.
A wind blocking piece 1056 can be arranged at the upper end of the condenser 105.
The wind blocking piece 1056 may be wind blocking sponge for filling a space between the upper end of the condenser 105 and the bent section. That is, the wind blocking piece 1056 covers the upper ends of the first straight section 1051, the second straight section 1052 and the transition curved section, and the upper end of the wind blocking piece 1056 should abut against the bent section to seal the upper end of the condenser 105, so that the situation that part of the air entering the compressor chamber passes through the space between the upper end of the condenser 105 and the bent section and does not pass through the condenser 105 is avoided, thus the air entering the compressor chamber is subjected to heat exchange through the condenser 105 as much as possible, and the heat dissipation effect of the condenser 105 is further improved.
In some embodiments, the refrigerator 100 may further include a wind blocking strip 107 extending forwards and rearwards. The wind blocking strip 107 is positioned between the bottom air inlet 110a and the bottom air outlet 110b, extends from the lower surface of the bottom horizontal section 113 to the lower surface of the supporting plate 112, and is connected to the lower end of the divider 117, so that the bottom air inlet 110a and the bottom air outlet 110b are completely isolated by the wind blocking strip 107 and the divider 117, and thus when the refrigerator 100 is positioned on a supporting surface, the space between the bottom wall of the refrigerator 100 and the supporting surface is transversely separated, so as to allow external air to enter the compressor chamber through the bottom air inlet 110a positioned on one lateral side of the wind blocking strip 107 under the action of the heat dissipation fan 106, sequentially flow through the condenser 105 and the compressor 104, and finally flow out from the bottom air outlet 110b positioned on the other lateral side of the wind blocking strip 107. Therefore, the bottom air inlet 110a and the bottom air outlet 110b are completely isolated, it is guaranteed that there is no cross flow of the external air entering the condenser 105 and the heat dissipating air exhausted from the compressor 104, and the heat dissipation efficiency is further guaranteed.
