The application relates to the technical field of refrigeration equipment, in particular to an open type spray humidification freezer.

Background

The refrigeration display cabinet is widely used in occasions such as supermarkets, restaurants and the like, is used for displaying and keeping fresh various commodities needing refrigeration, can meet the storage time and temperature of foods, can keep good display effect and is convenient for customers to obtain the commodities. For some commodities, some places are often directly stored by an open refrigerated cabinet, so that customers can conveniently take the commodities at any time, for example, a large supermarket with large flow of people directly uses the open refrigerated cabinet to store fresh vegetables and fruits. The refrigerator maintains a relatively low temperature in the refrigerator and keeps a constant temperature environment by means of the constantly blown refrigeration airflow, however, fresh vegetables and fruits contacting the flowing refrigeration airflow for a long time are easy to lose water or dehydrate on the surface, and the fresh-keeping effect of the vegetables and fruits is affected.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that refrigeration plant that prior art exists leads to article such as fresh vegetables and fruits of preserving among them to lose water easily, this application provides one kind and can be for the interior commodity of cabinet moisturizing's open type spraying humidification freezer.

In order to achieve the purpose, the technical scheme adopted by the application is as follows:

the utility model provides an open type spraying humidification freezer, is used for making and exporting the air supply arrangement of refrigeration air current including the cabinet body, setting at the internal air supply arrangement who is used for making and exports the refrigeration air current to and be used for absorbing the air return device that refrigeration air current made cabinet body surface formation air curtain, the internal humidification device who is used for making the spraying that still is equipped with of cabinet, the internal rear side of cabinet is equipped with the nozzle that supplies the spray to get into cabinet body display department, air supply arrangement and air return device are respectively including setting up air supply channel and the return air passageway on the cabinet body, air supply channel and return air passageway all are located one side relative with the nozzle.

The refrigerating principle of the open type refrigerated cabinet is that refrigerating airflow is sent out from an evaporator to the refrigerated cabinet through an air supply device in a certain direction and speed to exchange heat with articles stored in the refrigerated cabinet, and then returns to the evaporator through the suction effect of an air return opening to form an air curtain at the opening. The cooling air flow reduces the temperature in the cabinet body, and the air curtain enables a relatively closed environment to be formed in the refrigerated cabinet, so that the heat exchange between the interior of the refrigerated cabinet and the external environment is reduced. The open type refrigerated cabinet is generally used for storing commodities such as fresh vegetables and fruits and the like which need to be taken at any time by shops, supermarkets and the like, however, the refrigeration airflow in the refrigerated cabinet continuously passes through the commodities, so that the surfaces of the vegetables and fruits are easy to lose water, and the fresh-keeping effect of the commodities is influenced.

Set up humidification device in this scheme and release the spraying to the internal display department of cabinet, increase the internal humidity of cabinet, avoid commodity to lose moisture rotten. The atomizing nozzle and the air supply channel for releasing the atomizing are respectively arranged at the front end and the rear end of the cabinet body, so that the atomizing and the output refrigerating airflow are prevented from interfering with each other. And the return air channel should not set up in the homonymy with the nozzle equally, avoid the return air channel to absorb the spraying. Therefore, in order to solve the problems, the spray opening is arranged at the rear side in the cabinet body, the air supply channel and the air return channel are arranged at the front side, and the mutual interference of spraying and refrigerating airflow output is reduced to the greatest extent.

It should be noted that, according to the refrigeration principle of the existing open-type refrigerator, the module performing the refrigeration function mainly includes a refrigeration system and an air path system, the refrigeration system is used for producing and recovering the refrigeration airflow, and the air supply device and the air return device are part of the air path system and are used for producing the air curtain in the cabinet body. The improvement to wind path system in this scheme only relates to the improvement to air supply and return air passageway in order to cooperate humidification device, and other setting like the concrete equipment of refrigerating system and wind path system and circuit also can realize according to prior art, consequently, no longer gives unnecessary details in this application.

It should be noted that the conventional humidifying devices may be classified into an ultrasonic humidifier, a high-pressure fine mist humidifier, a dry vapor humidifier, an electrode humidifier, a centrifugal humidifier, an electrode humidifier, and the like according to the humidifying principle, and the humidifying device in the present application is not suitable for inputting mist in the form of high-temperature vapor because mist needs to be inputted into the refrigerator, and therefore, a humidifier that directly decomposes water into mist of small particles by high-frequency vibration or pulverization, such as an ultrasonic humidifier and a centrifugal humidifier, is preferably used in the present application.

Furthermore, the air supply channel outputs refrigerating airflow vertically upwards, and the return air channel is positioned below the air supply channel; the outside of the air supply channel is provided with a guide plate which enables the refrigerating airflow to move towards the direction in the cabinet body.

The scheme limits the direction of the output refrigerating airflow, so that the refrigerating airflow is vertically and upwards output at a certain speed, and moves towards the inside of the cabinet body after being blocked by the guide plate, and heat exchange is generated between the refrigerating airflow and commodities in the cabinet. Meanwhile, according to the motion law of gas, the temperature in the cabinet is lower than the ambient temperature, and the refrigerating airflow sinks in the cabinet body and is absorbed through an air return channel which is also positioned at the front side of the cabinet body after being fully contacted with commodities.

It is worth to be noted that the air supply device needs to provide larger kinetic energy for the output refrigerating airflow so as to ensure that the refrigerating airflow can move in the cabinet body according to a preset track, can reach the rear side in the cabinet body to form an air curtain, naturally sinks everywhere in the cabinet body, and is finally recovered by the air return device. Because the air supply channel and the air return channel are arranged on the same side of the cabinet body, when the kinetic energy of the output refrigerating airflow is insufficient, the refrigerating airflow is easy to move for a short distance and then is absorbed by the air return device.

Furthermore, the connecting line of the lower surfaces of the return air channel and the air supply channel is more than or equal to 90 degrees and less than 180 degrees.

Furthermore, a wind shield is arranged between the flow plate and the air supply channel. The vertical plane of the wind shield can guide the refrigerating airflow which just comes out from the air supply channel to maintain vertical upward movement for a certain distance, and then the refrigerating airflow is turned under the action of the wind shield.

Furthermore, the cabinet body is internally provided with a partition board used for partitioning the internal space of the cabinet body along the length direction, and the width of the partition board is smaller than the width of the cabinet body. When the internal space of cabinet needs to be layered, set up the less baffle of width in the cabinet body, avoid too wide baffle to cause the internal refrigeration of cabinet inhomogeneous.

Furthermore, the cabinet body is internally provided with spray nozzles which are matched with the number of the areas separated by the partition boards, and the spray nozzles are close to the upper ends of the areas.

The air flow in the cabinet has certain irregularity, after long-time refrigeration, the temperature of the cabinet is nearly the same, however, the essence of the spray produced by the humidifying device is water drop, which can be blocked by the partition board, therefore, when the cabinet is provided with the partition board for partitioning, in order to ensure that the commodities stored in each area can be moisturized, a plurality of spray nozzles are also arranged to release the spray to each area partitioned by the partition board.

Further, the bottom of the cabinet body is provided with rollers.

The beneficial effect of this application is: this application increases the interior humidity of cabinet through set up humidification device in the freezer, avoids the article of depositing to lose weight. Simultaneously, an air supply channel and an air return channel for releasing the atomizing nozzle and the refrigerated cabinet are respectively arranged on the front side and the rear side of the cabinet body, so that the mutual interference of the air path and the atomizing is avoided, and the refrigeration effect of the refrigerated cabinet is guaranteed.
