Description

Refrigerator with removable frame

The present invention relates to a frame structure of a refrigerating cabinet, more specifically, it is a frame structure that does not require additional power supply, has environmental protection performance, and can improve the maintenance convenience of the refrigerating cabinet.

Traditionally, the food industry, restaurants, convenience stores and other industries that have refrigeration or refrigeration needs will use refrigerators as their refrigeration equipment. Taking convenience stores as an example, there are usually 4-5 sides of refrigerators to store beverages, Food, and for general food and beverage tray traders, the number of refrigerators will be even more impressive. For refrigerators that operate for a long time or are in tropical or subtropical climates, take the Taiwan Food Hygiene Guidelines revised in 2020 as an example. The definition of refrigeration is below 7 degrees Celsius, and the freezing temperature needs to be below 18 degrees below zero. Therefore, the refrigerated cabinet is usually in a state where the temperature inside the cabinet door is low, and the temperature outside the cabinet door is high, so that fog beads are often condensed on the glass of the cabinet door.

Therefore, for the above-mentioned food industry, restaurants, convenience stores, or even factories, the generation of fog beads, in addition to blocking the sight through the glass cabinet door, the bigger problem is that the fog beads will gradually accumulate and continuously It slides from the cabinet door to the ground, causing water to gradually form around the refrigerator, so that people passing by are at risk of slipping. The public danger of electric shock or industrial safety accident is usually to avoid the accumulation of water around the refrigerator. The current refrigerator door frame or door is usually equipped with heat-conducting copper pipes or electric heating wires to use additional electricity to heat the above components. , raise the temperature of the cabinet door to close to or equal to the room temperature, thereby achieving the purpose of preventing fog beads from condensing on the cabinet door.

Under the existing conventional technical framework, such as the Republic of China Patent Publication No. TW 200829848, in the '848 case, it is to solve the problem that the glass door causes water vapor to condense on the door panel due to the temperature difference between the inside and outside. A door panel structure is proposed. The technical means is to use LED lights on the edge of the door panel, so that the LED lights can heat the temperature of the door panel during operation, so as to achieve the purpose of removing fog beads, and at the same time, in order to use the LED lights more efficiently. The generated heat energy has a reflector side part in the inner structure of the door panel, and the heat energy is transmitted inside the door panel by means of radiation, so that the heating of the door panel can be uniform. However, because the electricity required for the operation of the LED lights, the heat energy generated by the LED lights will conflict with the low temperature demand in the refrigerator, so that the refrigerator itself needs to consume more power to maintain the required low temperature. Therefore, the '848 Although the fog beads are successfully prevented from condensing on the cabinet door, there may still be room for improvement in the economy of electricity and the increasing awareness of environmental protection.

In order to solve the above deficiencies, the current Republic of China Patent Publication No. TW 571064 discloses a refrigerator. By arranging heat-conducting copper pipes or electric heating wires around the frame of the refrigerator, the waste heat released by the heat-dissipating part of the compressor can be converted into a refrigerator. The way of conduction guides it to the refrigerated cabinet door cabinet for heating, so as to prevent the condensation of water vapor. However, although the '064 case discussed the structure of arranging heat-conducting copper pipes around the frame of the refrigerated cabinet in an attempt to improve the problem of consuming extra electricity to heat the cabinet door, it still has shortcomings in terms of structure when it is used in industry. .

The disadvantage of conventional commercial or industrial refrigerated cabinets is that since the number of openings and closings during their use is much greater than that of household refrigerated cabinets, it means that the opportunity for heat exchange with the outside world will be great when the cabinet door is opened. It is used in household refrigerators, so it is impossible to use household refrigerators to prevent condensation of fog beads (or heat insulation, which means to prevent the temperature difference between the inside and the outside of the cabinet from being too large). , or adding a soft plastic (soft rubber) to the opening on the inner side of the refrigerated cabinet to achieve the purpose of heat insulation, and an electric heating wire or a heat-conducting copper tube must be used to strengthen the heat insulation effect.

However, during the manufacturing process of the refrigerated cabinet, the electric heating wire or the heat-conducting copper tube is usually buried around the cabinet body and the frame of the cabinet door in a closed manner, and the end of the heat-conducting copper tube or the heat-conducting copper wire is connected with additional power or The radiator of the compressor is used to provide heat energy, but in addition to making it difficult to install the heat-conducting copper tube or electric heating wire, the closed burial method will basically make it impossible to repair when the heat-conducting copper tube or electric heating wire fails. According to the statistics of the maintenance status of the refrigeration and air-conditioning industry in the past, the heat-conducting copper tube or electric heating wire is one of the components with the highest failure rate in the entire cold-floor cabinet. If the heat-conducting copper tube requires additional power, it will easily lead to The danger of short circuit, so its solution is often to directly connect the lead The power supply of the hot copper pipe or electric heating wire is removed, so that although the refrigerator can resume normal operation and use, it will lose the function of preventing condensation mist.

However, as mentioned above, if the refrigerator is used in a complex environment such as the food industry, restaurant, food street, factory, etc., the generation of fog beads will cause water accumulation around the refrigerator, so there is a public safety of electric shock and electric shock. Risk, under the current structure of refrigerated cabinets, if you want to fundamentally solve this problem, the only way is to replace the new refrigerated cabinet, which greatly increases the equipment cost of the enterprise and causes inconvenience. Therefore, for the existing refrigerated cabinet structure in the current market, there is still an urgent need for a refrigerated cabinet structure with the function of preventing condensation of fog beads, which can save the electricity when heating the cabinet door, and can facilitate the maintenance of the heat-conducting copper pipes or electric heating wires. Improve the above shortcomings.

In view of this, in order to solve the above problems, the present invention proposes a refrigerated cabinet with a detachable frame, the structure of which includes: a refrigerated cabinet body; a cabinet door, which is arranged on the refrigerated cabinet body; The frame is provided with a heat-conducting element arranged along the frame; a cover plate is arranged on the frame, covers the heat-conducting element, and is fastened to the frame by fixing screws. Wherein, in the embodiment of the present invention, the heat-conducting element may be a heat-conducting copper tube or an electric heating wire, and is heated by a heat source. Based on the above structure, since the cover plate is arranged on the frame of the refrigerator, the cover plate can be fixed and disassembled by fixing screws. Therefore, when the heat conducting element needs to be repaired, maintained or replaced, the cover plate can be easily removed without the need for For example, the conventional refrigerated cabinet completely solves the problem that the heat-conducting copper pipes or electric heating wires are buried in the refrigerated cabinet in a closed structure when leaving the factory, and cannot be maintained.

According to the present invention, a refrigerator with a detachable frame includes an adsorption element, so that the door can be fixed on the frame of the refrigerator body through the adsorption element when the door is closed. Wherein, the adsorption element is arranged on the cover plate, and the upper and lower ends of the cover plate have the structure of sliding rails, so that the adsorption element can be slidably inserted into the cover plate from the side of the cover plate through the sliding rails.

According to an embodiment of the present invention, the left and right sides of the cover plate can be configured as a trapezoidal structure, so that a plurality of cover plates can be fitted to cover the frame. Wherein, the number of cover plates can preferably be four.

In an embodiment of the present invention, the adsorption element may be a metal sheet or a magnet sheet, or any combination of the above two, and may also be capable of adsorbing the cabinet door when the cabinet door is in a closed state.

According to an embodiment of the present invention, one end of the heat-conducting copper pipe can be connected to the radiator in the compressor to guide the heat discharged from the radiator to the whole of the heat-conducting copper pipe, wherein the heat-conducting copper pipe can be laid on the refrigerating cabinet. Surroundings and above the frame, the heat-conducting copper tube can heat the temperature of the refrigerated cabinet to avoid condensation of fog beads on the refrigerated cabinet.
