Description

Technical Field

[0001] The invention relates to the technical field of refrigerators, and in particular to an anti-frost and anti-condensation structure for a refrigerator glass door. Background Art

[0002] Refrigerated refrigerators are widely used as refrigeration and preservation equipment. They use a glass door structure to display the items stored inside the refrigerator, such as upright commercial refrigerators for refrigerating beverages in stores.

[0003] The glass door of the refrigerator faces severe challenges of frost and condensation prevention during use. When the temperature inside the refrigerator is low and the humidity of the external environment is high or the temperature changes greatly, the water vapor in the air will liquefy or condense on the surface of the glass door when it encounters cold, that is, condensation or frosting occurs; the transparency of the glass door is greatly reduced, seriously affecting the visibility of the items inside the refrigerator, and affecting the use effect of the glass door; currently, laminated glass is generally used, and electric heating wires are added to the interlayer for heating. However, constant temperature heating by the electric heating wires can easily cause local overtemperature, which will destroy the refrigeration effect inside the refrigerator and increase the energy consumption of the refrigerator. It is too expensive to set up an external temperature sensor separately to achieve intelligent temperature control, which does not meet actual needs; therefore, consider how to slow down condensation and frosting on the refrigerator glass. In view of this, we propose an anti-frost and anti-condensation structure for the refrigerator glass door. Summary of the invention

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0042] See also Figure 1-11 The present invention describes the above technical solution in detail through the following embodiments:

[0043] The anti-frost and anti-condensation structure of the refrigerator glass door in this embodiment is as follows: Figure 1 and Figure 2 The structure shown is installed on the refrigerator body 1 at the door position, specifically including:

[0044] Glass door assembly 2, such as Figure 2 , Figure 5 and Figure 7 The structure shown includes a mounting seat 21 and a bottom bracket unit 22 rotatably mounted on the refrigerator body 1 . In this embodiment, a glass unit 23 is detachably mounted between the mounting seat 21 and the bottom bracket unit 22 .

[0045] It should be noted that if Figure 3-Figure 5As shown in the structure, the refrigerator body 1 includes an outer mounting cover seat 11 with a refrigerated inner compartment 12 installed inside, and a bottom plate 13 is installed at the bottom of the outer mounting cover seat 11; a partition 15 is installed between the bottom plate 13 and the refrigerated inner compartment 12, a ventilation cavity 101 is formed between the bottom plate 13 and the partition 15, and side sealing plates 16 are installed on both sides of the bottom plate 13 and the partition 15, and a compressor 14 for refrigeration is installed on the bottom plate 13. When the refrigerator is working, the compressor 14 will generate heat, and the heat needs to be discharged. This embodiment creatively provides a heat dissipation guide; specifically, a ventilation mesh plate 111 is provided on the outer mounting cover seat 11, and the ventilation mesh plate 111 corresponds to the position of the ventilation cavity 101, and an exhaust unit 17 is installed at the air outlet of the ventilation cavity 101 at the front end of the refrigerator body 1 through a mounting block 18, and the exhaust unit 17 corresponds to the position of the bottom bracket unit 22; Figure 4 The structure shown can form an airflow from the ventilation mesh plate 111, flowing through the compressor 14, the ventilation cavity 101 and the exhaust unit 17. When the glass door assembly 2 is closed, the hot air will pass through the bottom support unit 22 and blow the hot air flow to the glass unit 23, thereby slowing down condensation and frosting on the glass surface.

[0046] Specifically, Figure 6 As shown in the structure, the exhaust unit 17 in this embodiment includes a front air outlet plate 171 arranged at the front end of the refrigerator body 1 and located at the air outlet of the ventilation cavity 101, a fan 173 is installed on the front air outlet plate 171, and a heat dissipation hole 1711 is provided on the front air outlet plate 171, and the fan 173 is used to blow air outwards, and then discharge the heat generated by the operation of the refrigerator through the ventilation cavity 101 to form a hot air flow.

[0047] like Figure 7-Figure 9 The structure shown in the figure, the bottom bracket unit 22 of this embodiment includes an L-shaped mounting bracket 221, and the mounting bracket 221 is provided with an air outlet 2211 corresponding to the position of the front air outlet plate 171, that is, the hot air flow will be blown out from the air outlet 2211, but the glass unit 23 is vertically arranged, perpendicular to the air flow direction, so this embodiment Figure 8 In the structure shown, a vertical guide plate 222 is installed on the mounting bracket 221. The outer side of the vertical guide plate 222 is closed and an upward conductive channel is provided, that is, the hot air flow can be guided to the upward guide and discharge path, so that the hot air flow can be blown onto the glass unit 23 to avoid condensation and frost. In order to maintain the sealing fluidity of the air flow, the front air outlet plate 171 and the mounting bracket 221 are respectively provided with a first sealing strip 172 and a second sealing strip 223 at corresponding positions on the fitting surface, and the bottom plate 13 is sealed without heat dissipation holes, so that the heat can be fully discharged along the ventilation cavity 101.

[0048] In order to better utilize the waste heat generated by the refrigerator, Figure 7 , Fig.10 and Fig.11In the structure shown in the figure, the glass unit 23 includes a tempered glass door 232 installed between the mounting bracket 221 and the bottom bracket unit 22, and a third sealing strip 233 is installed on the inner side of the tempered glass door 232; an outer glass cover 231 is installed on the outer side of the tempered glass door 232, and a sandwich cavity for hot air flow to flow in is provided between the outer glass cover 231 and the tempered glass door 232, and the hot air flow will enter the sandwich cavity through the vertical guide plate 222; considering that the hot air flow has a fast flow speed, it will mainly be directly discharged through the exhaust hole 2311 provided at the top of the outer glass cover 231, and the durability is not good; therefore, in this embodiment, the hot air flow in the sandwich cavity is not as good as the exhaust hole 2311 provided at the top of the outer glass cover 231. A heat storage bin 234 is installed in the cavity from bottom to top, and the heat storage bin 234 corresponds to the position of the loading plate 3 in the refrigerator body 1, and a flow hole is provided on the body of the heat storage bin 234. The heat storage bin 234 is filled with metal copper particles for absorbing heat in the hot air flow. The hot air flow flows through the metal copper particles to achieve heat exchange, which increases the temperature of the metal copper particles, that is, the heat is evenly stored in the metal copper particles, thereby improving the waste heat utilization rate and the durability of anti-frost and anti-condensation. In other embodiments, an electric heating wire can be pre-buried in the heat storage bin 234, which can actively heat the metal copper particles and provide a supplementary heat source.
