The top end of the evaporator 12 is inclined towards one side of the back wall 112, and a yielding channel 140 for air to enter the lower part of the evaporator 12 from the air inlet 141 is formed between the top end of the evaporator 12 and the back wall 112 of the accommodating cavity; i.e. the air entering through the air inlet 141 cannot directly enter the evaporator 12 from the top end of the evaporator 12. In a specific implementation process, the top end of the evaporator 12 may be provided with an air deflector (not labeled in the figure), and the abdication channel 140 is a channel formed by sandwiching the air deflector with the rear wall 112 of the accommodating cavity.
Further, in the present utility model, the evaporation fan 13 is located above the evaporator 12, and an air outlet duct 150 extending from the position of the evaporation fan 13 toward the position of the air outlet 142 is formed below the top wall 111 of the unit box 11, and when the evaporation fan 13 operates, air cooled by the evaporator 12 is blown into the air outlet duct 150. More specifically, when the evaporation fan 13 is operated, due to the adsorption force of the air inlet end of the evaporation fan 13, the air entering the lower part of the evaporator 12 through the air inlet 141 and the abdication channel 140 can pass through the evaporator 12 to realize cooling and refrigeration, and the cool air entering the evaporation fan 13 can be discharged to the air outlet channel 150 through the air outlet end of the evaporation fan 13 and is discharged to the upper side space of the unit box 11 through the air outlet 142.
Referring now to FIG. 5, the present utility model also provides a display case having a bottom provided with an air-cooled unit 100 according to the present utility model. Specifically, the display cabinet of the present utility model further includes a cabinet body 21 having a storage cavity, and a door 22 disposed at a front side of the cabinet body 21 for opening or closing the cabinet body 21; the air-cooled unit 100 according to the present utility model is disposed at the bottom of the cabinet body 21, and the air outlet 142 is disposed near the door 22, and the air inlet 141 is disposed far from the door 22. Based on the above structure, when the air-cooled unit 100 is operated, the interior of the storage cavity of the cabinet body 21 can be refrigerated.
In some preferred embodiments of the present utility model, referring to fig. 5, in some examples, the storage cavity of the cabinet body 21 may further be provided with partitions 210 dividing the storage cavity into multiple layers, and each partition 210 is provided with a plurality of through holes (not shown) penetrating up and down in order to facilitate air circulation between the multiple layers.

Further, as a preferred embodiment of the present utility model, referring to fig. 1, the air outlet duct 150 in this embodiment is formed by sandwiching the top wall 111 with the duct partition 15 located at the lower side of the top wall 111, and the evaporation fan 13 is a centrifugal fan with its air inlet end facing downward.

Referring to fig. 1, in the present embodiment, the first receiving chamber further has a cold accumulation chamber 101 located below the air duct partition 15 and in communication with the upper space of the evaporator 12 at the front side of the evaporator 12. In the circulating refrigeration of the air-cooled unit 100, when one circulating refrigeration process is finished, a certain amount of cold can be accumulated in the cold accumulation cavity 101, so that when the next circulating refrigeration is started and the temperature of the evaporator 12 is not reduced to a lower temperature, the accumulated cold in the cold accumulation cavity 101 can supplement the cold, the cold entering the air outlet duct 150 is ensured to have a temperature not too high, and the display cabinet has a relatively stable refrigeration effect.
As shown in fig. 1 and 4, in some embodiments of the present utility model, at least two evaporation fans 13 are disposed above the evaporator 12 in a width direction of the unit box 11 and are disposed in parallel to supply air to the air outlet duct 150. Considering that display cases are generally of a wide size, multiple evaporator fans 13 can make refrigeration more uniform. In the embodiment shown in fig. 4, two evaporating fans 13 are arranged in parallel, and the evaporating fans 13 guide the air out into the air-out duct 150 through the volute 130.
Referring to fig. 4, in order to make the air outlet 142 more uniform, the air outlet 1420 in this embodiment is formed by a plurality of through holes 1420 which are arranged at intervals and penetrate through the top wall. Preferably, in the implementation process, the distribution span of the plurality of through holes 1420 in the width direction of the unit box 11 is not smaller than the distribution span of the evaporation fan 13, as shown in fig. 4, that is, W1 is not greater than W2.
As shown in fig. 1, the unit box 11 in the present utility model further has a bottom wall 114 corresponding to the bottom side of the first accommodating cavity, and a collecting area (not labeled in the drawing) for collecting accumulated water is formed in the bottom wall 114 at a position right below the evaporator 12, and a diversion hole 1140 for guiding out the accumulated water in the first accommodating cavity is formed in the collecting area. In order to facilitate the collection of the water, in the collection area, the level of the upper surface of the bottom wall 114 gradually decreases in the direction approaching the diversion hole 1140; that is, a slope for the water to flow toward the diversion hole 1140 is formed in the confluence region.
In this embodiment, as shown in fig. 1, the unit box 11 further has a second accommodating cavity 102 formed below the bottom wall 114, and a water receiving box 16 for receiving the accumulated water guided out by the flow guiding hole 1140 is disposed in the second accommodating cavity 102. In other embodiments of the present utility model, the accumulated water guided out of the flow guiding hole 1140 may also be directly guided out of the unit box 11 through a pipe (not shown).
Further, the air-cooled unit 100 in this embodiment further includes a compressor 17, a condenser 18, and a condensing fan 19 disposed in the second accommodating chamber 101; preferably, the water receiving box 16 is disposed at the top of the compressor 17, so that water in the water receiving box 16 can cool the compressor 17 to a certain extent by evaporation during the operation of the compressor 17, and the service life of the compressor 17 can be prolonged.
In addition, in order to implement the intelligent defrosting control of the air-cooled unit 100 in the present utility model, the air-cooled unit 100 in the present utility model further includes a defrosting unit that heats the evaporator 12 during operation, a weighing unit that senses a current weight of the evaporator 12, a storage unit that stores parent data of the weight of the evaporator 12 in different operation states and without frosting, a comparison judging unit that compares the sensed weight of the weighing unit with the parent data corresponding to the current state stored in the storage unit and judges whether the frosting amount of the evaporator 12 exceeds a preset threshold, and a control unit that controls the operation of the defrosting unit when the frosting amount of the evaporator 12 exceeds the preset threshold.
Based on the arrangement of the intelligent defrosting control related structure, the air-cooled unit can pertinently realize defrosting of the evaporator, and further the refrigerating efficiency of the air-cooled unit is reliably improved.
As shown in fig. 2 and 3, unlike the embodiment shown in fig. 1, a rotation support portion 1120 rotatably connected to the top end of the evaporator 12 and supporting the top end of the evaporator 12 is fixed in the first housing chamber 101. In this embodiment, the rotation support portion 1120 is a bracket fixed on the rear wall 112 of the unit case 11, and the top end of the evaporator 12 is rotatably connected to the bracket through the rotation shaft 120.
Further, in this embodiment, the weighing module is a pressure sensor 10 disposed at the bottom end of the evaporator 12, and because the top end of the evaporator 12 is rotatably connected with the rotating support portion 1120, the pressure of the evaporator 12 to the pressure sensor 10 is necessarily different when the frost amount on the surface of the evaporator 12 is different. In practice, based on this pressure data, it is easier to calculate the current weight of the evaporator 12.
In a specific implementation process, the defrosting unit in this embodiment may be a mechanism such as an electric heating wire. The maternal data stored in the storage unit can be obtained by: when the air-cooled unit 100 is first powered on, the weight of the evaporator 12 in different operation states is detected and acquired by the pressure sensor 10 in the first operation period, and the acquired data can be used as female parent data. In addition, the 'preset threshold' involved in the utility model can be adjusted according to actual requirements.
It will be appreciated that, since the rotation support portion 1120 also has a certain support to the evaporator 12, the data sensed by the pressure sensor 10 does not completely coincide with the actual weight of the evaporator 12, but the data sensed by the pressure sensor 10 and the weight of the evaporator 12 have a linear relationship, and based on this, the weight of the evaporator 12 can be obtained easily through the data sensed by the pressure sensor 10.
Although the present disclosure describes embodiments, not every embodiment is described in terms of a single embodiment, and such description is for clarity only, and one skilled in the art will recognize that the embodiments may be combined in any suitable manner to form other embodiments that will be apparent to those skilled in the art.
The above list of detailed descriptions is only specific to practical embodiments of the present utility model, and they are not intended to limit the scope of the present utility model, and all equivalent embodiments or modifications that do not depart from the spirit of the present utility model should be included in the scope of the present utility model.
