Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of refrigeration and freezing equipment, and particularly relates to a refrigerator. BACKGROUND

[0002] With the development of the market, higher and higher requirements are put forward for commercial refrigerators. In terms of internal volume of the refrigerator, it is required to maximize the internal volume under the condition that the external dimensions of the refrigerator are determined, so as to place more goods. Therefore, the refrigerator with a top-mounted air duct structure cannot meet the market requirements, and the volume utilization rate of the refrigerator with a rear-mounted air duct is higher, and more goods can be loaded, so the refrigerator with a rear-mounted air duct becomes a better choice.

[0003] In terms of cooling speed (i.e. the time for reducing the temperature in the refrigerator to the set value, in hours), it is required that the refrigerator with a rear-mounted air duct is not slower than the refrigerator with a top-mounted air duct, and even faster. However, if only the size of the rear-mounted air duct is made large to accelerate the cooling speed, the internal volume, cost, energy efficiency and other key parameters will be affected, which will be contrary to the customer's requirements. Therefore, the design of the rear-mounted air duct is particularly important, and it is necessary to make the cooling speed fastest under the premise of ensuring the internal volume, cost, energy efficiency and other parameters.

[0004] In general, the greater the air volume blown out through the rear-mounted air duct, the greater the heat exchange in the refrigerator, and the faster the cooling speed. However, the air sucked into the air duct will cause air speed loss due to air leakage in the air duct, the main reason for which is the assembly gap of different parts and the air leakage points caused by the structure of the parts themselves, thereby causing the condition of air speed loss, and finally affecting the refrigeration efficiency of the whole machine.

[0069] In order to make the technical problems, technical solutions and beneficial effects of the present application more clearly understood, the present application will be further described in detail below in combination with the figures and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0070] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0071] ​​​It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0072] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0073] In terms of cold speed (the time to reduce the temperature in the refrigerator to the set value, in hours), the back-type air duct refrigerator is required to be no slower than the top-mounted refrigerator, and even faster. However, if only to speed up the cold speed, the size of the back-type air duct is made very large, which will affect the internal volume, as well as the key parameters such as cost and energy efficiency, which will be contrary to the needs of customers. Therefore, the design of the back-type air duct is particularly important, and must be the fastest in cold speed under the premise of ensuring internal volume, cost, energy efficiency, etc.

[0074] In general, the larger the air volume blown out through the back-type air duct, the greater the heat exchange in the refrigerator, and the faster the cold speed.

[0075] The air volume, that is, the volume of air blown out from the back-type air duct per unit time, can be calculated using the following formula: V=S*v, where V is the air volume, S is the cross-sectional area of the air outlet, and v is the air speed of the air outlet. For the same refrigerator product, the size, internal size, inventory, etc. are determined, the size of the air duct is basically determined, and the design change of the cross-sectional area S of the air outlet is small, which has little effect on the air volume. It can be considered as a fixed value. From the above formula, the larger the air speed v of the air outlet, the larger the air volume, and the faster the cold speed. Therefore, the design of the back-type air duct should focus on improving the air speed of the air outlet.

[0076] In general, the main factors affecting the air speed of the air outlet are as follows:

[0077] 1. The air inlet wind speed: the air sucked from the air inlet maintains a certain initial speed, and after being accelerated by the fan, it is beneficial to improve the air outlet wind speed. The air inlet volume can be calculated by the following formula: V1=S1*v1, wherein V1 is the air inlet volume, S1 is the air inlet cross-sectional area, and v1 is the air inlet wind speed. As can be seen from the above formula, the air inlet volume is affected by the cross-sectional area of the air inlet and the wind speed of the air inlet. However, for the air inlet, the fan is constant, so the fan suction volume V1 can be regarded as a fixed value, and therefore reducing the air inlet cross-sectional area S1 (i.e. reducing the size of the air inlet) can increase the air inlet wind speed v1.

[0078] 2. The air sucked into the air duct loses speed due to air leakage in the air duct, mainly due to the assembly gap of different parts and the air leakage points caused by the structure of the parts themselves, resulting in a situation of speed loss.

[0079] 3. The traditional evaporator has perforations on both sides for assembling the cold pipe, which has a large amount of air leakage and a large impact on wind speed and flow.

[0080] Therefore, the embodiments of the present application provide a new type of refrigerator, which re-designs the structure of the back-type air duct in view of the situation that air leakage in the back-type air duct easily affects the cooling speed, and plugs the air leakage between the fan and the output part of the cold quantity, effectively solving the problem of air leakage in the back-type air duct structure of the traditional refrigerator, which easily causes speed loss and affects the refrigeration efficiency. Now it will be described in detail.

[0081] Please refer to the arrow direction in Figure 1 , Figure 2 and Figure 3 ( Figure 2 , which is the flow path of the cold quantity), the refrigerator comprises an inner container 100 and a refrigeration air duct 200, and the refrigeration air duct 200 is arranged at the back of the inner container 100. The "back of the inner container" here can be understood as the side opposite to the opening of the inner container (i.e. the opening where the refrigerator door is located).

[0082] The refrigerator further comprises at least a fan 1, an evaporator 2, and a wind blocking assembly 3. In the embodiment, as shown in Figure 3 and Figure 4 , the fan 1, the evaporator 2, and the air outlet part are preferably arranged in sequence from top to bottom, so that the fan 1 is located at the upper part of the refrigeration air duct 200, the middle part is the evaporator 2, and the lower part is the air outlet part.

[0083] As shown in Figure 5 , the fan 1 can preferably adopt a volute type fan, and the output port of the fan 1 faces the upper end of the evaporator 2 and is arranged close to the upper end of the evaporator 2. The fan 1 is used to output the cold quantity on the evaporator 2 to the air outlet part of the refrigeration air duct 200.

[0084] The evaporator 2 is connected with a refrigeration mechanism (not shown in the figure) on the refrigerator, and generates cold energy in the refrigeration air duct 200. The refrigeration mechanism on the refrigerator can include a compressor, a condenser, etc. The evaporator 2 is connected with the refrigeration mechanism through a cold pipe, and transmits the generated cold energy into the refrigeration air duct 200.

[0085] The air blocking assembly 3 can be a combination of two symmetrical parts or multiple parts. The air blocking assembly 3 is arranged on both sides of the evaporator 2 and between the output port of the fan 1 and the air outlet part of the refrigeration air duct 200. The air blocking assembly 3 is used to fill the hollow parts on both sides of the gap between the fan 1 and the evaporator 2, and the hollow parts on the structure on both sides of the evaporator 2.

[0086] Compared with the prior art, the refrigerator provided in the embodiment of the present application adopts a back-type air duct design, and the refrigeration air duct 200 is arranged on the back of the inner container 100 of the refrigerator, which is beneficial to save the occupied space and thus increase the volume utilization rate of the inner container 100. In the refrigerator of the embodiment of the present application, the fan 1 generates airflow and outputs the airflow to the evaporator 2, and the evaporator 2 generates cold energy which is output to the air outlet part of the refrigeration air duct 200, thereby outputting the cold energy to the inner container 100 of the refrigerator.

[0087] In order to ensure the cooling speed of the refrigerator with the back-type refrigeration air duct 200, and in view of the air leakage parts between the assembly gaps of the components in the refrigeration air duct 200 and the air leakage parts on the structure of the components themselves, the air blocking assembly 3 is further arranged in the refrigerator of the embodiment of the present application. The air blocking assembly 3 is used to fill the hollow parts on both sides of the gap between the fan 1 and the evaporator 2, and the hollow parts on the structure on both sides of the evaporator 2, thereby preventing the cold energy in the refrigeration air duct 200 from easily flowing out from these hollow parts, effectively solving the air leakage problem of the refrigeration air duct 200 and improving the refrigeration efficiency.

[0088] The specific structure of the air blocking assembly 3 includes but is not limited to the following forms:

[0089] In an embodiment of the present application, please refer to Figure 4 and Figure 5 The air blocking assembly 3 includes air blocking plates 31 respectively arranged on both sides of the evaporator 2, and at least part of the air blocking plates 31 fills the hollow parts on the structure on the sides of the evaporator 2, thereby effectively reducing the loss of the cold energy generated by the evaporator 2 from the structure on the sides of the evaporator 2.

[0090] The evaporator 2 comprises a cold pipe 21 and a plate row 22 arranged on the cold pipe 21. In the embodiment, the cold pipe 21 is preferably arranged in a serpentine shape, and the plate row 22 comprises a plurality of spaced metal plate members, and the serpentine cold pipe 21 is arranged in the metal plate members, and the metal plate members diffuse the cold on the cold pipe 21 outward. The air flow generated by the fan 1 passes through the metal plate members and outputs the cold on the metal plate members to the air outlet of the refrigeration air duct 200.

[0091] As shown in Figure 6 and Figure 7 , the plate members on both sides of the plate row 22 have perforations 23 for penetrating the cold pipe 21. Since the cold pipe 21 only occupies part of the space in the perforation 23 and cannot completely fill the perforation 23, the parts in the perforation 23 that are not filled by the cold pipe 21 form hollow parts on the side structure of the evaporator 2. The cold generated on the evaporator 2 is easily lost from the perforations 23, forming a leakage condition that affects the cooling speed.

[0092] In this embodiment, the baffle plate 31 has a baffle 311 corresponding to the position of the perforation 23 and a clamping groove 312 between adjacent baffles 311. The baffle 311 on the baffle plate 31 corresponds to the position of the perforation 23 on the plate member and is used to plug the perforation 23, and the clamping groove 312 on the baffle plate 31 is used to clamp the cold pipe 21 penetrating the perforation 23.

[0093] In this way, the baffle plate 31 cooperates with the side structure of the evaporator 2. On the one hand, the baffle 311 on the baffle plate 31 plugs each perforation 23 that is prone to leakage, effectively reducing the loss of cold generated on the evaporator 2 from the side structure of the evaporator 2, and successfully solving the leakage problem on the structure of the evaporator 2. On the other hand, the clamping groove 312 on the baffle plate 31 can clamp the cold pipe 21 penetrating the perforation 23, so that the baffle plate 31 can better fit the plate member on the side of the evaporator 2, thereby improving the structural compactness between the components and facilitating the reduction of the occupied space.

[0094] For the evaporator 2 mounting structure in the refrigerator according to the embodiments of the present application, the conventional mounting method is to use the perforation fixing method of fasteners such as screws, so as to fix the entire evaporator 2 in the refrigeration air duct 200. Specifically, the screw fixing method needs to increase the hole positions matched with the evaporator 2, and install the nuts to be able to be fixed by penetrating, and needs to have a certain operation space in the refrigeration air duct 200. However, in the embodiments of the present application, a part of the refrigeration air duct 200 is the back wall surface of the inner container 100, and another part is the base plate of the refrigeration air duct, which are combined to constitute the entire refrigeration air duct 200. This means that the screws need to be set outside the refrigeration air duct 200 to penetrate into the inside of the refrigeration air duct 200, and pass through the hole positions on the evaporator 2 to fix the evaporator 2. The alignment operation in the safety process is very difficult, which increases the installation operation difficulty of the evaporator 2, and therefore the refrigeration air duct 200 in the embodiments of the present application cannot be applied.

[0095] In this regard, the evaporator 2 fixing structure in the refrigerator is redesigned in the embodiments of the present application. In one embodiment of the present application, please refer to Figure 8 , Figure 7 and Figure 5 , the refrigerator further comprises a hanging piece 4 for fixing the evaporator 2, the inner container 100 is provided with a mounting hole 101 communicated with the refrigeration air duct 200, the hanging piece 4 extends into the refrigeration air duct 200 from the mounting hole 101 and is fixed on the cold pipe 21, so as to fix the evaporator 2 in the refrigeration air duct 200.

[0096] In the embodiments, as shown in Figure 6 , the hanging piece 4 is preferably a structure similar to a clamp, the hanging piece 4 comprises an end cap 41 and a pair of clamping pieces 42 integrally formed with the end cap 41, the end cap 41 is used for manual operation during installation and is used to be arranged on the inner container 100. The pair of clamping pieces 42 on the end cap 41 are symmetrically arranged, and extend into the refrigeration air duct 200 from the mounting hole 101 on the inner container 100 during installation, and are clamped on the cold pipe 21 of the evaporator 2. As shown in Figure 7 , the plate row 22 on the evaporator 2 has a gap 20 for exposing the cold pipe 21, the gap 20 corresponds in position to the mounting hole 101 on the inner container 100, so that the pair of clamping pieces 42 extend into the refrigeration air duct 200 from the mounting hole 101, and are clamped on the cold pipe 21 of the gap 20.

[0097] In this way, the hanging piece 4 is used to clamp and fix the cold pipe 21 on the evaporator 2 by extending into the refrigeration air duct 200 from the mounting hole 101 of the inner container 100, without the need to install fasteners such as screws for fixing, which effectively reduces the operation difficulty of installing the evaporator 2 in the refrigeration air duct 200, and further improves the installation efficiency.

[0098] In actual application, the installation hole 101 formed on the inner container 100 will affect the sealing performance of the refrigeration air duct 200, and the installation hole 101 is easy to form a leakage position of the refrigeration air duct 200, which causes the cold energy in the refrigeration air duct 200 to be easily lost.

[0099] In this case, on the basis of the above, in one embodiment of the present application, please refer to Figure 7 and Figure 3 , the inner container 100 further comprises a sealing gasket 102 arranged on the installation hole 101, and the sealing gasket 102 has a sealing glue for fixing the hanging piece 4.

[0100] In this embodiment, as shown in Figure 8 , the end cap 41 of the hanging piece 4 is a rectangular piece; correspondingly, the sealing gasket 102 is a rectangular piece, and a through hole is formed on the sealing gasket 102, which is matched with the shape of the installation hole 101 on the inner container 100. The two end faces of the sealing gasket 102 are smeared with sealing glue, and the hanging piece 4 is fixed and pasted on the outer periphery of the installation hole 101 of the inner container 100 by the sealing glue.

[0101] In this way, the hanging piece 4 is fixed and pasted on the installation hole 101 of the inner container 100 through the sealing gasket 102, without the need for additional fasteners such as screws for fixing, which not only simplifies the fixing structure of the evaporator 2, but also ensures the fixing effect of the evaporator 2. In addition, the sealing gasket 102 can also seal the installation hole 101 on the inner container 100, which is beneficial to prevent the cold energy in the refrigeration air duct 200 from flowing out from the installation hole 101, and effectively improve the sealing effect.

[0102] For the specific structure of the wind blocking assembly 3, in another embodiment of the present application, please refer to Figure 3 and Figure 8 , the wind blocking assembly 3 further comprises a first protrusion 32 arranged on the inner container 100, and the first protrusion 32 is filled in the hollow position on both sides of the gap between the output port of the fan 1 and the evaporator 2.

[0103] In this embodiment, as shown in Figure 3 , the output port of the fan 1 and the evaporator 2 have a safety isolation space, so that a gap is formed between the output port of the fan 1 and the evaporator 2, and a first hollow position 201 which is easy to lose airflow is formed on both sides of the gap. Correspondingly, as shown in Figure 9 , the inner container 100 is provided with a first protrusion 32 arranged on the corresponding position, and the first protrusion 32 can be stamped on the inner container 100 according to production requirements, and the first protrusion 32 can be embedded in the first hollow position 201 on both sides of the gap between the output port of the fan 1 and the evaporator 2.

[0104] In this way, the first convex 32 provided on the inner container 100 is embedded in the hollowed parts on both sides of the gap between the output port of the fan 1 and the evaporator 2, effectively preventing the loss of cold energy in the refrigeration air duct 200 from the hollowed parts.

[0105] In actual application, defrosting water is easily generated on the evaporator 2, which drips downward and is easily accumulated on the air outlet part of the refrigeration air duct 200, affecting the output of cold energy of the refrigeration air duct 200.

[0106] In this regard, in one embodiment of the present application, referring to Figure 10 , Figure 8 and Figure 9 , the refrigerator of the embodiment of the present application further comprises a water receiving mechanism 5 for collecting defrosting water, which comprises at least two layers of water receiving platforms 51, and the vertical projection of the evaporator 2 is located within the water receiving range of the at least two layers of water receiving platforms 51.

[0107] In this way, the water receiving mechanism 5 is provided below the evaporator 2, and each water receiving platform 51 of the water receiving mechanism 5 collects the defrosting water dripping from the evaporator 2, effectively expanding the water receiving range and improving the water receiving effect.

[0108] For the specific structure of the air blocking assembly 3, in the third embodiment of the present application, referring to Figure 9 and Figure 9 , the air blocking assembly 3 further comprises a second convex 33 provided on the inner container 100, which is filled in the hollowed parts on both sides of the gap between the evaporator 2 and the water receiving mechanism 5.

[0109] In this embodiment, as shown in Figure 8 , there is a safe isolation space between the evaporator 2 and the uppermost water receiving platform 51 of the water receiving mechanism 5, and a vent hole 202 communicating with the inside of the inner container 100 can be preferably provided in the safe isolation space as an air outlet part of the refrigeration air duct 200, so that the cold energy in the refrigeration air duct 200 can be output from the vent hole 202 to the inside of the inner container 100. The defrosting water dripping from the evaporator 2 will directly fall into the water receiving platform 51 of the water receiving mechanism 5, without affecting the normal output of cold energy of the refrigeration air duct 200, effectively improving the shunt effect.

[0110] In addition, as shown in Figure 1 , the safe isolation space also forms a gap between the evaporator 2 and the uppermost water receiving platform 51 of the water receiving mechanism 5, and second hollowed parts 203 prone to loss of cold energy are formed on both sides of the gap. In cooperation, as shown in Figure 9As shown, the inner container 100 is provided with a second protruding bump 33 corresponding to the above-mentioned positions, which can also be punched on the inner container 100 according to production requirements. The second protruding bump 33 can be embedded in the second hollowed position 203 on both sides of the gap between the evaporator 2 and the uppermost water receiving platform 51 of the water receiving mechanism 5.

[0111] In this way, the second protruding bump 33 on the inner container 100 is embedded in the hollowed position on both sides of the gap between the evaporator 2 and the uppermost water receiving platform 51, effectively preventing the cold energy in the refrigeration air duct 200 from flowing out of these hollowed positions.

[0112] For the water drainage structure on the water receiving platform 51, in the related art, there is a structure in which the received water flows into each water receiving platform 51 from top to bottom in turn, and is drained from the drainage channel on the bottommost water receiving platform 51. This structure is a one-way flow guide structure, and the drainage channel on the bottommost water receiving platform 51 is the only drainage port. If the drainage channel on the bottommost water receiving platform 51 is blocked, the water on the entire water receiving mechanism 5 cannot be drained.

[0113] In this embodiment, as shown in Figure 10 , each water receiving platform 51 is provided with an independently arranged drainage channel 52. The inner container 100 is provided with a drainage groove 103 communicating with each drainage channel 52, and the drainage groove 103 extends to the bottom of the inner container 100.

[0114] Please refer to Figure 11 , Figure 9 and Figure 10 , each water receiving platform 51 is provided with a drainage channel 52 on one side, and the water received by the water receiving platform 51 flows into the drainage groove 103 on the inner container 100 from each drainage channel 52, and flows along the drainage groove 103 to the bottom of the inner container 100. Here, a drainage pipe (not shown) can be preferably installed on the bottom of the inner container 100 to communicate with the drainage groove 103 on the inner container 100, so that the water can be drained to a designated place by using the installed drainage pipe.

[0115] In this way, the drainage channel 52 on each water receiving platform 51 is independently arranged and directs the received water to the drainage groove 103 of the inner container 100 for drainage, effectively preventing the blockage of individual water receiving platforms 51 from affecting the overall drainage, and further ensuring the drainage effect of the water receiving mechanism 5.

[0116] Preferably, as shown in Figure 12 , the water receiving surface of the above-mentioned water receiving platform 51 is inclined to the inlet of the drainage channel 52, so that the water on the water receiving platform 51 can flow naturally to the inlet of the drainage channel 52, effectively preventing the water level on the water receiving platform 51 from overflowing due to excessive accumulation, and further improving the drainage effect of each water receiving platform 51.

[0117] In another embodiment of the present application (not shown in the figure), the water receiving table 51 is provided with two water drainage channels 52 on both sides, so that the water on the water receiving table 51 can be drained through either of the two water drainage channels 52.

[0118] In this way, when one of the water drainage channels 52 on the water receiving table 51 is blocked, the water can be drained through the other water drainage channel 52 on the same water receiving table 51, effectively preventing the blocking of the water drainage channel 52 on the water receiving table 51 from affecting the drainage, thereby improving the drainage effect of the water receiving table 51.

[0119] In another embodiment of the present application, please refer to Figure 12 and ​ , the two adjacent water receiving tables 51 are arranged in an up-down staggered manner, so that a flow guide channel 53 for the flow of cold air is formed between the two adjacent water receiving tables 51, and the bottom of the water receiving table 51 at the bottom layer has an air outlet 54 which is in communication with the flow guide channel 53.

[0120] In this way, the bottom of the water receiving mechanism 5 forms another air outlet on the refrigeration air duct 200, and the cold air flowing down from the evaporator 2 flows through the flow guide channel 53 between the adjacent water receiving tables 51 and is finally output from the air outlet 54 at the bottom of the water receiving table 51 at the bottom layer. This is beneficial to separate the received water and the cold air flow and drain and output them respectively, effectively improving the flow separation effect of the water receiving mechanism 5.

[0121] In actual application, the cold air flow flowing down from the evaporator 2 is prone to vortex at the air outlet 54 at the bottom of the water receiving table 51 at the bottom layer, resulting in a loss of wind speed.

[0122] Therefore, on the basis of the above, please refer to ​ , the air outlet 54 at the bottom of the water receiving table 51 at the bottom layer is preferably a pipe opening in the form of a frame. Forming a pipe opening in the form of a frame at the air outlet 54 is beneficial to prevent the cold air flow at the air outlet 54 from easily spreading, and eliminates the vortex at the air outlet 54, so that the cold air flow can be concentrated at the air outlet 54, effectively avoiding the loss of wind speed, and thereby improving the output effect.

[0123] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
