Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation hoods, in particular to a ventilation hood used for refrigeration products. Background Art

[0002] Medical refrigeration equipment, due to its high performance requirements, usually uses an external condenser to maintain the heat exchange efficiency of the product. The surface of the condenser is generally covered with fine metal fins or steel wire pipe structures, which can increase the surface area and thus improve the heat transfer efficiency. The working principle is to flow the high-temperature and high-pressure refrigerant through the internal pipes, and quickly cool it under the cooling of the outside air, so that the refrigerant changes from gas to liquid. In this process, the condenser uses the structural advantages of metal fins or steel wire pipes to increase the surface area and achieve better heat exchange effect. It is extremely important to keep the condenser clean so that the metal fins or steel wire pipes can fully exert the heat exchange effect. Therefore, the condenser, compressor and other components are assembled in the box, and the box is generally set as a ventilation hood. Medical refrigeration equipment is generally cleaned regularly by the manufacturer's after-sales personnel or the engineering personnel of the user unit, and tools are needed to disassemble the ventilation hood, which is time-consuming and laborious. Therefore, it is urgent to solve.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not 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 utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Example

[0028] See also Figure 1-6 As shown:

[0029] The utility model provides a ventilation hood used for refrigeration products, comprising: a hood body plate 10, a bottom plate 30 and a cover plate. The upper surface of the bottom plate 30 is used to install a condenser.

[0030] There are at least three cover plates 10, which are respectively connected vertically to the upper surface of the bottom plate 30, and the adjacent cover plates 10 are plugged together at the head and tail to form a mounting chamber for the condenser; the cover plate covers the top of the mounting chamber. A slot is provided on the upper surface of the bottom plate 30; a tenon 11 is provided at the bottom of the cover plate 10; the tenon 11 is plugged into the slot.

[0031] In actual use, after the condenser is installed on the base plate 30, the operator then snaps the cover plate 10 onto the base plate 30 in sequence, and the cover plates 10 are plugged into each other at the ends, and finally the cover plate is replaced on the cover plate 10 to form a ventilation hood. When the condenser needs to be repaired, since the ventilation hood is spliced, the operator can quickly disassemble it, thereby saving disassembly time. It can be seen that setting the ventilation hood to the splicing mode is more convenient for both the installation and maintenance of the condenser. It not only reduces the difficulty of installing and disassembling the ventilation hood, but also saves time and improves maintenance efficiency.

[0032] A clamping bolt hole 31 is provided on the side of the bottom plate 30 ; the clamping bolt hole 31 is communicated with the clamping groove on the upper surface of the bottom plate 30 , and a bolt abutting against the side wall of the tenon 11 is installed in the clamping bolt hole 31 .

[0033] In order to prevent the cover plate 10 from being easily taken away, in actual use, after the cover plate 10 is clamped on the base plate 30, the bolt is installed along the clamping bolt hole 31, and the handle at one end of the bolt is rotated until the other end of the bolt abuts against the side wall of the tenon 11 in the clamping groove, so that the connection between the cover plate 10 and the base plate 30 will be more stable.

[0034] It also includes an inspection door 20; an inspection opening is provided on the cover plate 10; the inspection door 20 is installed at the inspection opening, and one side of the inspection door 20 is rotatably connected to one side of the inspection opening, and a hinge 21 is provided at the rotatable connection.

[0035] With such an arrangement, when the condenser only requires simple maintenance, the operator only needs to open the inspection door 20 to inspect it without opening the ventilation hood, thus saving the time for disassembling and assembling the ventilation hood, being convenient and improving the maintenance efficiency.

[0036] The hinge member 21 is mainly composed of a pin shaft 211 , a base 212 , an open washer 213 , a spring 214 and an adjustment cylinder 215 .

[0037] The actual setting is that an outer turn-over edge is provided on the inspection door 20, and the outer turn-over edge is located at the rotation connection between the inspection door 20 and the inspection opening, and a notch is provided on the outer turn-over edge.

[0038] The inspection opening is provided with an inner turn-down edge, which is located at the rotation connection between the inspection opening and the inspection door 20, and a through hole is provided on the inner turn-down edge.

[0039] A convex ring is provided at the top of the base 212, and the diameter of the convex ring is larger than the diameter of the notch. The bottom end of the base 212 passes through the notch and forms a threaded connection with the top of the adjustment tube 215. The open washer 213 is clamped at the bottom end of the base 212; the diameter of the bottom end of the base 212 is smaller than the diameter of the top of the adjustment tube 215, and the inner diameter of the open washer 213 is the same as the diameter of the bottom end of the base 212, so that the open washer 213 and the convex ring are clamped at the upper and lower ends of the notch, and the adjustment tube 215 is tightened to press the open washer 213 against the lower end of the notch, so that the entire base 212 can be fixed at the notch.

[0040] The spring 214 is vertically placed in the adjustment tube 215 , the bottom of the pin 211 is in contact with the top of the spring 214 , and the top of the pin 211 passes through the base 212 and is plugged into the through hole.

[0041] With such an arrangement, during actual installation, the operator presses the top of the pin shaft 211 to retract it into the adjustment cylinder 215, and then aligns it with the through hole and releases it. The pin shaft 211 can be stably inserted into the through hole with the support of the spring 214, thereby facilitating the disassembly and assembly work between the inspection door 20 and the inspection port.

[0042] An adjusting block is provided at the bottom of the adjusting cylinder 215; the adjusting block is threadedly connected to the inner wall at the bottom of the adjusting cylinder 215, and the adjusting block can move along the vertical direction of the adjusting cylinder 215. By such a configuration, when the resilience of the spring 214 decays, the adjusting block at the bottom of the adjusting cylinder 215 can be rotated to move in the adjusting cylinder 215, compressing the spring 214, thereby making the supporting force of the spring 214 on the bottom of the pin 211 greater, so that the inspection door 20 is installed more stably at the inspection port.

[0043] A magnet 23 is installed on the other side of the inspection door 20. Through the magnet 23, the inspection door 20 and the inspection port form magnetic attraction, so that the operator can open the inspection door 20 easily.

[0044] In order to facilitate the operator to open the inspection door 20 , a door handle 22 is provided on the inspection door 20 .

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
