Quick-freezing reset switch device for refrigeration equipment and refrigeration equipment with same

Abstract

The invention discloses a quick-freezing reset switch device for refrigeration equipment and refrigeration equipment with the same. The quick-freezing reset switch device comprises two switch elastic pieces with touch points, an operating piece, a stopping component and a triggering piece. A gap is formed between the touch points in a first direction. The operating piece is adjacent to the touch points, and is formed to be pushed from an initial position to a triggering position by a first external force along the first direction. The operating piece pushes the touch points to contact when positioned at the triggering position. The stopping component is formed to stop the operating piece when the operating piece is positioned at the triggering position. The triggering piece is adjacent to the stopping piece, and is formed to trigger the stopping component to reset the operating piece from the triggering position when the environment temperature is lower than or equal to a preset threshold value. Through arrangement of the triggering piece, a function that the refrigeration equipment can adjust quick-freezing time automatically according to load volume of the refrigeration equipment is realized. In addition, the quick-freezing reset switch device is simple and reliable in structure, and low in cost.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a quick-freezing reset switch device for refrigeration equipment and the refrigeration equipment provided therewith. Background technique [0002] At present, the European Union has proposed new environmental protection regulations for export refrigeration equipment, requiring refrigeration equipment with quick-freezing function to automatically exit the quick-freeze mode within 72 hours to avoid unnecessary energy waste caused by long-term operation of the compressor in quick-freeze mode. [0003] The quick-freezing method used by traditional mechanical refrigeration equipment is to set a switch to directly short-circuit the thermostat. For example, if the user puts too many items in one time and needs to be refrigerated or frozen, in order to meet the requirements of quick-freezing and quick-cooling, press the quick-freeze switch, directly short-circuit the thermostat, at...

Problems solved by technology

However, although this method has the advantage of low cost, if the user forgets to reset, the compressor will be in a non-stop state for a long time, resulting in unnecessary waste of energy consumption

[0004] However, if Chinese refrigeration equipment companies want their products to comply with the new EU regulations, they must implement the above functions. The methods they use are usually as follows: First, add a mechanical timer. At present, ordinary mechanical timers have very short timing It is difficult to exceed 6 hours, and there is noise, so it is not suitable for application in refrigeration equipment; the second is to increase the electric timer, which is composed of a motor and a reduction gear set, similar to a microwave oven timer, but this timer is usually The cost is high. For low-end mechanical temperature-controlled refrigeration equipment, such a cost combined with the low gross profit of export products is not suitable; there is also an electronic timing module, but the second solution has the same problem, and the cost is relatively high. high, also inappropriate

[0005] In addition, there is another problem: the refrigeration equipment cannot automatically adjust the quick-freezing time according to the size of its load. That is to say, if the user puts in 5kg of items at a time, and then starts the quick-freezing mode, for the ordinary quick-freezing timing exit concept, after 6 hours If the user only puts in 1kg of items and then activates the quick-freezing mode, the quick-freezing may be completed in 3 hours, and the quick-freezing will cause energy waste if the remaining time is not over.
