Abstract
Description
Technical Field
[0001] This utility model relates to the field of fresh air system technology, and more specifically to a vertical dual-cold-source fresh air dehumidifier. Background Technology
[0002] With increasing demands for indoor air quality and the continued development of the domestic real estate and decoration markets, the market demand for fresh air dehumidifiers is constantly growing. Domestic companies are continuously investing in the research and development of fresh air dehumidifiers, launching new products with features such as high efficiency, energy saving, and intelligent control. For example, dual-cold-source fresh air dehumidifiers improve dehumidification efficiency while reducing energy consumption through dual-cold-source technology.
[0003] A vertical dual-source dehumidifier is a device used to regulate indoor air humidity and temperature. It combines the functions of a fresh air system and a dehumidifier, providing fresh air while simultaneously dehumidifying it. The vertical dual-source dehumidifier includes components such as a casing, compressor, surface cooler, evaporator, and condenser. Its working principle is as follows: outdoor fresh air first enters the device through the fresh air inlet, passing through a pre-filter and a high-efficiency filter. The filtered fresh air then enters the surface cooler for initial cooling and dehumidification. Afterward, the fresh air enters the evaporator and condenser assembly, where it is further cooled and dehumidified by refrigerant. During the dehumidification process, the temperature of the air supplied to the room can be controlled by adjusting the operating status of the refrigerant compressor.
[0004] The casing of a vertical dual-source dehumidifier is not a single piece; it consists of two shells joined together, with seams at the joint. If the dehumidifier is used in a humid environment or is exposed to rain, water can seep into these seams, causing internal parts to rust and shortening the machine's lifespan. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a vertical dual-cold-source fresh air dehumidifier, which can effectively prevent water from entering the joints of the casing, prevent internal parts from rusting, and extend the service life of the machine.
[0006] The technical solution of this utility model is to provide a vertical dual-cold-source fresh air dehumidifier with the following structure, including a housing, wherein the housing includes an upper housing and a lower housing; the upper housing includes an upper outer shell and an upper inner liner, the upper inner liner is disposed inside the upper outer shell, the lower end of the upper outer shell has a first inwardly bent edge, and the lower end of the upper inner liner is limited to the first bent edge; the lower housing includes a lower outer shell and a lower inner liner, the lower inner liner is disposed inside the lower outer shell, the upper end of the lower outer shell has a second inwardly bent edge, and the upper end of the lower inner liner is limited to the second bent edge; the first bent edge and the second bent edge are fitted together.
[0007] With the above structure, the vertical dual-cold-source fresh air dehumidifier of this utility model has the following advantages compared with the prior art:
[0008] Because the lower end of the upper outer shell of this utility model's vertical dual-cold-source fresh air dehumidifier is provided with an inwardly bent first bend, and the lower end of the upper inner lining is limited to the first bend; the upper end of the lower outer shell is provided with an inwardly bent second bend, and the upper end of the lower inner lining is limited to the second bend; the first bend and the second bend are fitted together. In this way, rainwater entering the gap between the upper and lower shells will not enter the machine casing; only some water will remain between the first and second bends. This effectively prevents water from entering the joints of the casing, avoids rusting of internal parts, and extends the machine's service life.
[0009] As an improvement, the lower end of the upper inner liner has a third outwardly bent edge, which is attached to the inner side of the first bent edge; the upper end of the lower inner liner has a fourth outwardly bent edge, which is attached to the inner side of the second bent edge. With this structure, the upper inner liner can be stably installed inside the upper outer shell, and the lower inner liner can be stably installed inside the lower outer shell.
[0010] As an improvement, the end of the third bent edge protrudes upward to form a first flange, which is attached to the inner side of the upper outer shell and fixedly connected to it. With this structure, the mounting structure between the upper inner liner and the upper outer shell is stable and secure.
[0011] As an improvement, the end of the fourth bent edge protrudes downward to form a second flange, which is attached to the inner side of the lower outer shell and fixedly connected to it. With this structure, the installation structure between the lower inner liner and the lower outer shell is stable and secure.
[0012] As an improvement, the end of the second bent edge protrudes upward to form a third flange, which is attached to the outside of the upper inner liner and fixedly connected to it. With this structure, even in heavy rain, the rainwater remaining between the first and second bent edges will not enter the casing due to the blocking effect of the third flange, thus more effectively preventing water from entering the casing seams.
