Detailed Description

The embodiment of the invention firstly provides a door body for a refrigerating and freezing device. The door body for the refrigeration and freezing device in the embodiment of the invention generally comprises a display control assembly for providing a display touch function, a heat dissipation air duct for dissipating heat of the display control assembly and a heat dissipation fan arranged in the heat dissipation air duct.

Fig. 1 is a schematic structural view of a door body 1 for a refrigerating and freezing apparatus according to an embodiment of the present invention, and fig. 2 is a schematic partially exploded structural view of the door body 1 for a refrigerating and freezing apparatus according to an embodiment of the present invention. Referring to fig. 1 to 2, a door body 1 for a refrigeration and freezing apparatus according to an embodiment of the present invention may include a panel 10 for forming a front portion of the door body 1, a display control assembly 30 for providing a display touch function, and a door body foaming assembly 20 for forming a rear portion of the door body 1. An accommodating cavity for accommodating the display control assembly 30 and a heat dissipation air duct communicated with the accommodating cavity and the environment space are defined between the door body foaming assembly 20 and the panel 10, and the display control assembly 30 is accommodated in the accommodating cavity. The heat dissipation air duct can circulate with the ambient space, and the heat generated by the display control assembly 30 can be dissipated through the heat dissipation air duct, so that the heat accumulation is avoided, and the temperature around the display control assembly 30 is reduced. The heat dissipation fan 50 is arranged in the heat dissipation air channel, and the heat dissipation fan 50 can accelerate air flow between the heat dissipation air channel and an environment space, so that heat generated by the display control assembly 30 can be effectively taken away, and an obvious condensation prevention effect can be generated through accelerated circulation of air. In some embodiments, the intake air fan 50 may be a centrifugal fan. The centrifugal fan has small pressure loss and higher air supply efficiency, so that the heat radiation effect can be improved.

In particular, the heat dissipation fan 50 is configured to be controllably turned on or off according to the temperature of the display control assembly 30. The present invention can determine whether the forced heat dissipation process is required according to the actual situation by turning on or off the heat dissipation fan 50 according to the temperature of the display control assembly 30. When the temperature of the display control assembly 30 is low, natural convection heat dissipation is performed only through the heat dissipation air duct or natural heat dissipation is performed through heat radiation, so that the heat dissipation requirement of the display control assembly 30 can be met, and the energy waste caused by opening the heat dissipation fan 50 when the temperature of the display control assembly 30 is low can be avoided. And can take away the produced heat of display control subassembly 30 more effectively when display control subassembly 30's temperature is higher, but also can produce obvious condensation effect of preventing through the circulation with higher speed of air, improve display control subassembly 30's quality, prolong its life.

In some embodiments, a heat dissipation damper 2631 is disposed in the heat dissipation air duct, and the heat dissipation damper 2631 is configured to be controllably opened or closed according to the temperature of the display control component 30 to turn on or off the heat dissipation air duct. According to the invention, the heat dissipation air channel is switched on or off according to the temperature of the display control assembly 30, and whether heat dissipation treatment is required or not can be determined according to actual conditions, so that the heat dissipation requirement of the display control assembly 30 is ensured, the dustproof requirement of the display control assembly 30 is met, and the working stability of the display control assembly 30 is improved. In addition, since the heat dissipation fan 50 is used to perform forced heat dissipation, the opening time of the heat dissipation damper 2631 can be greatly shortened, which is more favorable for meeting the dustproof requirement of the display control assembly 30.

In some embodiments, heat rejection blower 50 and heat rejection damper 2631 may be further configured to: when the temperature of the display control assembly 30 rises to a preset first temperature threshold value, the display control assembly 30 is controlled to be started so as to perform forced heat dissipation on the display control assembly 30. That is, the radiator fan 50 is further configured to: controlled turn on when the temperature of the display control assembly 30 rises to a first temperature threshold; and heat dissipation damper 2631 is also further configured to: controlled to turn on when the temperature of the display control assembly 30 rises to a first temperature threshold. Generally, when the temperature of the display control assembly 30 rises to the first temperature threshold, the heat dissipation fan 50 and the heat dissipation damper 2631 may be simultaneously opened. Of course, the heat dissipation fan 50 may be opened later than the heat dissipation damper 2631. It should be understood by those skilled in the art that the first temperature threshold referred to in the embodiments of the present invention may be a temperature value set by a user or a designer according to actual conditions or experimental results. For example, the first temperature threshold may be 40 ℃, 50 ℃, or 60 ℃, etc.

When the radiator fan 50 and the radiator damper 2631 are opened when the temperature of the display control component 30 rises to the first temperature threshold, the temperature of the display control component 30 generally decreases. Accordingly, in some embodiments, the heat rejection blower 50 and the heat rejection damper 2631 may be further configured to: and is controllably turned off when the temperature of the display control assembly 30 drops to a preset second temperature threshold. That is, the radiator fan 50 is further configured to: controllably shut down when the temperature of display control assembly 30 drops to a second temperature threshold; and heat dissipation damper 2631 is also further configured to: and controllably shut down when the temperature of the display control assembly 30 drops to a second temperature threshold. In general, when the temperature of display control assembly 30 drops to the second temperature threshold, heat dissipation fan 50 and heat dissipation damper 2631 may be closed simultaneously. Of course, radiator fan 50 may be closed slightly before radiator shutter 2631. Similarly, the second temperature threshold may be a temperature value set by a user or a designer according to actual conditions or experimental results, and the value of the temperature value is usually smaller than the first temperature threshold. For example, the second temperature threshold may be 10 ℃, 15 ℃, or 20 ℃, etc.

In some embodiments, the door body 1 may further include: a temperature sensor configured to detect a temperature of the display control component 30 after the display control component 30 receives a touch operation.

The heat dissipation fan 50 may be disposed in the upper heat dissipation air duct, or may be disposed in the lower heat dissipation air duct.

In some embodiments, the upper heat dissipation air duct may include a plurality of sub-air ducts disposed at intervals and communicating with the accommodating cavity. For example, the upper heat dissipation air duct may include two, three, or four equal sub-air ducts. One heat dissipation damper 2631 may be disposed in each sub-air duct, and each heat dissipation damper 2631 may be configured to be controllably opened or closed according to the temperature of the display control assembly 30 to turn on or off its corresponding sub-air duct. That is, in the case that the number of the heat dissipation air ducts is plural, the opening or closing of the heat dissipation damper 2631 in each heat dissipation air duct can be controlled simultaneously according to the temperature of the display control component 30.
