Detailed Description
The present embodiment provides a refrigerator 100, and the refrigerator 100 according to the embodiment of the present invention is described below with reference to fig. 1 to 5. In the following description, the orientations of "up", "down", "front", "back", "top", "bottom", "lateral", etc., referred to in the specification are defined in terms of spatial positional relationships in a normal operation state of the refrigerator 100, and "front", "back" are directions indicated in fig. 1, as shown in fig. 5, and "lateral" refers to a direction parallel to the width direction of the refrigerator 100.
The refrigerator 100 includes a lowermost storage bladder 130 and an evaporator 101, the storage bladder 130 defining a cooling chamber 132 therein and a storage compartment 131 above the cooling chamber 132, the evaporator 101 being disposed in the cooling chamber 132 and configured to cool air flowing therethrough to form cooled air to be supplied to the storage compartment 131.
In traditional refrigerator, the below space of refrigerator generally is storing space, and this storing space position is lower, and the user need bend down or squat by a wide margin and just can get the operation of putting article to the storing space of below, and the user of not being convenient for uses, especially inconvenient old man uses. And, the evaporimeter of traditional refrigerator generally is located the rear of the storing space of below, has occupied the rear region of below storing space for the depth of below storing space reduces, moreover, the press cabin of traditional refrigerator generally is located the rear below of below storing space, below storing space inevitably will give way for the press cabin, lead to below storing space dysmorphism, further reduced the volume of below storing space, and be not convenient for deposit of the great and difficult segmentation article of volume.
In the refrigerator 100 of the embodiment, since the lowermost space is the cooling chamber 132, the height of the storage chamber 131 above the cooling chamber 132 is raised, the stooping degree of the user when the user takes and places the articles in the storage chamber 131 is reduced, and the use experience of the user is improved. In addition, the evaporator 101 no longer occupies the rear space of the storage compartment 131, ensuring the depth of the storage compartment 131. Moreover, the press cabin 104 can be located behind and below the cooling chamber 132, the cooling chamber 132 gives way for the press cabin 104, and the storage chamber 131 does not need to give way for the press cabin 104 any more, is formed into a rectangular space with a large volume and a regular shape, is convenient for placing articles with a large volume and difficult division, and solves the problem that pain spots of large articles cannot be placed in the storage chamber 131.
In the novel refrigerator 100 of this embodiment, in order to facilitate the drainage of the defrosting water falling from the evaporator 101, the drain opening 130c may be formed on the upper surface of the bottom wall of the storage container 130, and the distance between the drain opening 130c and the evaporator 101 may have a certain influence on the drainage of the drain opening 130c, the volume of the space in the storage compartment 131 above the cooling chamber 132, and the like.
Before the present application, the applicant designed a refrigerator with a distance between the two of 15mm and 35mm, as described in the specification of the CN201920242279.2 utility model, the design size can ensure the inclination angle of the inclined plane of the water receiving section of the storage liner, so that the defrosting water falling on the inclined plane of the water receiving section smoothly slides to the water discharge port. Meanwhile, the inclination angle of the drain pipe is also guaranteed, so that foreign matters falling in the drain pipe are discharged to the evaporating dish along the drain pipe, and the foreign matters are prevented from staying in the drain pipe to influence the discharge of defrosting water. However, the refrigerator having the above design size may have other technical problems while having the above advantages, for example, if ice cubes remain after defrosting of the evaporator 101, the ice cubes may block the space between the evaporator 101 and the water outlet 130c, or even the water outlet 130c, and over time, the water outlet 130c may be blocked, so that the defrosting water cannot be discharged when the evaporator 101 is next defrosted, and the refrigerating performance of the refrigerator 100 may be affected.
Accordingly, the present inventors have proposed a refrigerator 100 having a different design size from the above in order to solve the problem that the drain port 130c may be blocked by ice. Specifically, the distance H between the lowest point of the projection of the drain opening 130c on the vertical plane and the lowest point of the projection of the evaporator 101 on the vertical plane may be greater than 35mm, for example, H may be 37mm, 39mm, 41mm, 43mm, 45mm, and the like, and preferably, the upper limit of H may be 50mm, that is, H may not be greater than 50mm, so as to avoid that the space of the storage liner 130 is excessively occupied by the cooling chamber 132 due to the increase of the H value, and thus, the influence on the volume of the storage compartment 131 above the cooling chamber 132 may be reduced. However, in some embodiments, H values greater than 50mm are also possible for different types of refrigerators.
In the refrigerator 100 of the embodiment, the value of H is limited to a range larger than 35mm, so that the distance between the drain port 130c and the evaporator 101 is increased, the problem of ice blockage of the drain port 130c can be avoided, and the refrigeration performance of the refrigerator 100 is ensured. The design size can be applied to a large-volume refrigerator, the storage chamber 131 of the large-volume refrigerator is large in volume, and the influence of the increase of H on the volume of the storage chamber 131 is relatively small. But the design size does not exclude the application to small volume refrigerators.
The evaporator 101 and the drain port 130c may be both regular or irregular in shape. In some embodiments, the evaporator 101 may be disposed in the cooling chamber 132 as a whole in a flat cube shape, i.e., the long and wide faces of the evaporator 101 are parallel to the horizontal plane, the thickness face is disposed perpendicular to the horizontal plane, and the thickness dimension is significantly smaller than the length dimension of the evaporator 101. This reduces the height of the evaporator 101, reduces the height of the cooling chamber 132, and increases the volume of the storage compartment 131 above the cooling chamber 132.
In some embodiments, drain 130c may be a regular circle or square. In the embodiment where the evaporator 101 has a flat cubic shape and the drain opening 130c has a circular or square shape, the aforementioned H is a distance between the lower wall surface of the evaporator 101 and the drain opening 130 c. The aforementioned vertical plane may be a vertical plane parallel to a lateral side wall of the refrigerator 100 or a vertical plane parallel to a rear surface of the refrigerator 100.
The upper surface of the bottom wall of the storage liner 130 includes a water receiving section 135 located below the evaporator 101, the water receiving section 135 is gradually recessed from the periphery to the middle, so as to form a slope surface with a downward slope, so that the defrosted water slides down along the slope surface of the water receiving section 135 to the lowest position of the water receiving section 135, the lowest position of the water receiving section 135 is formed with the aforementioned water outlet 130c, and the water outlet 130c is located right below the evaporator 101. The lower side of the area covered by the entire lower surface of the evaporator 101 is directly below the evaporator 101.
In the embodiment where the drain opening 130c is located right below the evaporator 101 and the evaporator 101 is shaped like a flat cube, the aforementioned H is the vertical distance between the lower surface of the evaporator 101 and the drain opening 130 c.
In the foregoing embodiment, the water receiving section 135 is defined by the bottom wall of the storage bladder 130 itself. In an alternative embodiment, a water-receiving tray may be additionally disposed on the bottom wall of the storage bladder 130, the water-receiving tray may be recessed from the periphery to the middle, and an opening is formed at the lowest position of the water-receiving tray, and the opening is opposite to and communicated with the water outlet 130 c.
The refrigerator 100 has a compressor compartment defined therein, and a compressor, a condenser 105, a heat radiation fan, and the like are provided in the compressor compartment. An evaporation pan (not shown) may be disposed below the condenser 105, and one end of the drain pipe is connected to the drain port 130c and the other end extends into the evaporation pan to guide the defrosting water into the evaporation pan so as to evaporate the defrosting water by heat dissipation of the condenser 105.
The refrigerator 100 may further include a supply air fan 103 and a supply air duct 134, wherein the supply air fan 103 is configured to promote air circulation between the cooling chamber 132 and the storage compartment 131, so that cooling air may be continuously supplied to the storage compartment 131 to ensure that the temperature of the storage compartment 131 reaches a corresponding target temperature. The air duct 134 may be disposed inside the rear wall of the storage inner container 130, and may be respectively communicated with the cooling chamber 132 and the storage compartment 131, and configured to deliver the cooling air into the storage compartment 131, and as shown in fig. 5, an air outlet 134a for blowing the cooling air into the storage compartment 131 is formed in a front wall of the air duct 134.
The refrigerator 100 further includes a partition 102 disposed in the space defined by the storage bladder 130 and configured to partition the space defined by the storage bladder 130 into an upper storage compartment 131 and a cooling compartment 132 below the storage compartment 131. Thus, the storage compartment 131 and the cooling compartment 132 are two independent spaces. The upper surface of the upper wall of the partition 102 may constitute a bottom wall of the storage compartment 131, and the lower surface of the upper wall of the partition 102 may constitute a top wall of the cooling compartment 132.
In one embodiment, a front return air inlet 102a may be formed at a front side of the partition 102, and return air of the storage compartment 131 may enter the cooling compartment 132 through the front return air inlet 102a to be recooled by the evaporator 101, thereby continuously supplying cooling air to the storage compartment 131. Because the front return air inlet 102a is formed in the front side of the partition 102, and the partition 102 is located in the space defined by the storage liner 130, the storage compartment 131 can be communicated with the cooling chamber 132 directly through the front return air inlet 102a without arranging a return air duct, so that complicated design and installation are omitted, and the cost is reduced.
In view of the above-mentioned design of returning air through the front return air inlet 102a at the front side of the cooling chamber 132, other problems may arise, for example, the user may see the front return air inlet 102a directly after opening the first door 133 at the front side of the storage liner 130, which is not visually pleasing; foreign objects may enter the cooling compartment 132 through the front return air inlet 102a, causing the front return air inlet 102a to be blocked.
In view of the above, another embodiment of the present application provides a refrigerator 100 having a return air inlet in a different location from that described above. Specifically, the lateral side wall of the storage liner 130 is formed with a return air outlet 130a communicated with the storage compartment 131, and the lateral side wall of the storage liner 130 is further formed with a side return air inlet 130b communicated with the cooling compartment 132, and the return air outlet 130a and the side return air inlet 130b are communicated through the return air duct 106, that is, the return air duct 106 is located outside the lateral side wall of the storage liner 130, and both ends of the return air duct are respectively communicated with the return air outlet 130a and the side return air inlet 130b, so that the return air in the storage compartment 131 can be conveyed into the cooling compartment 132 to be cooled by the evaporator 101 again, so as to continuously supply cooling air to the storage compartment 131. In this way, the above-mentioned series of problems caused by the front side air return of the cooling compartment 132 are avoided, and the operation safety of the refrigerator 100 and the user experience are improved.
The number of the return air outlets 130a, the number of the side return air inlets 130b, and the return air duct 106 may be two, and the two return air outlets 130a and the two side return air inlets 130b are respectively formed on two lateral sidewalls of the storage container 130, that is, one lateral sidewall of the storage container 130 is formed with one return air outlet 130a and one side return air inlet 130b, and the other lateral sidewall is formed with the other return air outlet 130a and the other side return air inlet 130 b. The two return air ducts 106 may be respectively located outside two lateral walls of the storage container 130, two ends of one of the return air ducts 106 are respectively communicated with the return air outlet 130a and the side return air inlet 130b located on one of the lateral walls, and two ends of the other return air duct 106 are respectively communicated with the return air outlet 130a and the side return air inlet 130b located on the other lateral wall. Thus, the return air quantity entering the cooling chamber 132 is ensured, and the temperature of the storage compartment 131 is accelerated.
The side return air inlet 130b can be close to the front end of the side wall in the front-rear direction, the air supply duct 134 is arranged at the rear side of the storage compartment 131, and the cooling chamber 132 is arranged at the lower side of the storage compartment 131, so that cooling air flows into the air supply duct 134 from front to back and is conveyed into the storage compartment 131 through the air supply duct 134, and the side return air inlet 130b is positioned more forward, so that return air entering the cooling chamber 132 from the side return air inlet 130b enters the evaporator 101 from the front end face of the evaporator 101, flows through the evaporator 101 from front to back and then enters the air supply duct 134, and therefore the return air can be fully cooled by the evaporator 101.
The side return air inlet 130b may be vertically adjacent the top wall of the cooling compartment 132, reducing the distance from the return air outlet 130a and reducing the length and footprint of the return air duct 106. The return air outlet 130a can be close to the bottom wall of the storage compartment 131 in the vertical direction, so that the cooling air entering the storage compartment 131 can flow through the whole storage compartment 131, and can fully exchange heat with the articles stored in the storage compartment 131, and on the other hand, the distance between the return air outlet 130a and the side return air inlet 130b can be further shortened, and the length and the occupied space of the return air duct 106 are reduced.
The return air outlet 130a may be located closer to the front end of the side wall in the front-to-rear direction than the side return air inlet 130b, as shown in fig. 4, and the return air outlet 130a is located directly above the side return air inlet 130b, so that the return air duct 106 is vertically arranged, and has the smallest length and the smallest space.
A wind blocking component 107 can be arranged between the upper end face of the evaporator 101 and the top wall of the cooling chamber 132, and the wind blocking component 107 can be set to block return wind entering the cooling chamber 132 from flowing between the upper end face of the evaporator 101 and the top wall of the cooling chamber 132 so as to prevent the return wind from entering the air supply duct 134 without being cooled by the evaporator 101, thereby ensuring the cooling effect of the storage chamber 131.
The wind shielding component 107 can comprise wind shielding foam, so that the effect of heat insulation is achieved while shielding wind, and due to the lowest temperature at the evaporator 101, the influence of the temperature of the evaporator 101 on the storage compartment 131 above is avoided due to the existence of the wind shielding component 107.
The storage liner 130 may be a freezing liner, and accordingly, the storage compartment 131 is a freezing compartment, while the freezing compartment has the lowest temperature relative to the temperature-changing compartment and the refrigerating compartment, and the cooling compartment 132 is distributed below the freezing compartment, which is beneficial to maintaining the lowest temperature of the freezing compartment.
The refrigerator 100 may further include a temperature-changing liner 140 positioned above the freezing liner, and a refrigerating liner 120 positioned above the temperature-changing liner 140, the temperature-changing liner 140 defining a temperature-changing chamber 141, and the refrigerating liner 120 defining a refrigerating chamber 121. The front side of the freezing inner container is provided with a first door 133 for opening and closing the freezing chamber, the front side of the temperature-changing inner container 140 is provided with a second door 142 for opening and closing the temperature-changing chamber 141, and the front side of the refrigerating inner container 120 is provided with a third door 122 for opening and closing the refrigerating chamber 121.
The refrigerator 100 may supply cooling air to the variable temperature compartment 141 by additionally providing another supply air duct and another return air duct to circulate air between the variable temperature compartment 141 and the cooling compartment 132. The refrigerator 100 may further provide cooling air to the refrigerating chamber 121 by additionally providing another blowing duct and another return duct to circulate air between the refrigerating chamber 121 and the cooling chamber 132. The refrigerator 100 may be configured to have a dual refrigeration cycle in which another evaporator and another fan are separately added to the refrigerating inner container 120 and cool air cooled by the other evaporator is supplied to the refrigerating chamber 121.
As can be appreciated by those skilled in the art, the refrigerator 100 further includes a housing that is insulated from the various liners by a foam layer, and correspondingly, the compressor compartment 104 is also insulated from the cooling compartment 132 by a foam layer.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
