Description

Sterilizing cabinet

This utility model relates to a kind of disinfection cabinet.

Present disinfection cabinet has four big classes.One class is the high-temperature steam sterilization cabinet, and structure is comparatively complicated, and heat time heating time is long, requires good airproof performance; Second class is the far infrared high-temperature disinfection cabinet, and is simple in structure, but requires to use high temperature resistant aging material, and it is fast inadequately to heat up, and the thermal efficiency is not high enough, and the heating tube life-span falls short of; The 3rd class is an ozone disinfection cabinet, relatively power saving, but sealing requirements height, and ozone leaks when excessive harmful; The 4th class is a ultraviolet disinfection cabinet, than power saving, but easily produces " dead angle ", causes sterilization not exclusively, and produces ozone simultaneously, leaks easily, and is harmful.Except that the second class far infrared high-temperature disinfection cabinet, the equal no drying effect of its excess-three class.

The purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of quick heating, heat imitate high, the life-span is long, ozone free generation and the high-temperature disinfection cabinet of oven dry effect is arranged.

This utility model is achieved in that being fixed with radiator on the two sides of " PTC " heating constitutes heater; Heater is installed in bottom, rear portion, sidepiece or top in the disinfection cabinet; With controller control sterilisation temp or disinfecting time.

This utility model can also be installed one or more small-sized fanses in disinfection cabinet, the wind direction of fan is aimed at heater, also the wind direction of fan can be faced upward or downward, and makes the cabinet inner air convection to help heater heat radiation and in-cabinet temperature even.

The utility model will be further described below in conjunction with drawings and Examples.

Fig. 1 is a structure chart of the present utility model.Fig. 1 (a)～Fig. 1 (d) is several different embodiments.

Fig. 2 is the structure chart of heater of the present utility model.Fig. 2 (a)～Fig. 2 (d) is several different embodiments.

Fig. 3 is an electrical schematic diagram of the present utility model.Fig. 3 (a) and Fig. 3 (b) are respectively two kinds of schemes.

Disinfection cabinet as shown in Figure 1 is made up of shell (1), inner shell (2), thermal insulation board (3), Hierarchical Network (4), heater (5), controller (6), on and off switch (7) display lamp (8) and cabinet door (not shown).Controller (6), on and off switch (7) and display lamp (8) are installed in the disinfection cabinet left, also can be installed in top or other positions.

Low capacity disinfection cabinet to shown in Fig. 1 (a) only uses a heater (5).Heater (5) is installed in the bottom in the cabinet, and rise in the back because air is heated, and forms cross-ventilation, makes temperature more even.

For the disinfection cabinet of the intermediate size shown in Fig. 1 (b), can use two heaters (5,9), one of them heater (5) is installed in the bottom, and another heater (9) is installed in the rear portion, and is even to shorten the heating-up time and to be beneficial to in-cabinet temperature.Also two heaters can be placed on the bottom of both sides respectively.

For jumbo disinfection cabinet, available heater (5,9,10) more than three or three is installed on positions such as the interior bottom of cabinet, rear portion, both sides respectively.Fig. 1 (c) is a kind of structure wherein.

In order to make in-cabinet temperature more even, small fan can be installed in cabinet.The number of small fan is decided with cabinet amount of capacity and heater number, small fan of general heater configuration, and the wind direction of fan is aimed at heater.A heater (5) and a fan (11) only are installed also can resembling shown in Fig. 1 (d), and the power of heater (5) is decided with the cabinet capacity, the big high-power heater of disinfection cabinet, little disinfection cabinet small-power heater.

Heater shown in Figure 2, with bolt (15) that " PTC " heating (13) is fixing with the radiator (12,16,17,18) on both sides.Charged for preventing radiator, between " PTC " heating and radiator, be separated by as mica sheet with insulating heat-conduction material (14).

Radiator can be a fin (12) of being made parallel equidistant shape by some lamellules, is made of the heater of circular, square, strip or other shapes " PTC " heating and so parallel equidistant fin.Fig. 2 (a) is a kind of scheme wherein.

Radiator also can be the bigger heat sink of area (16,17,18), with the part of heat sink as disinfection cabinet inner shell or inner shell, as Fig. 2 (c, d) shown in.

In addition, can also be in " PTC " one side fixing cooling fins, another side is heat sink fixedly, shown in Fig. 2 (b).

Circuit diagram shown in Fig. 3 (a), controller T are temperature controller.Display lamp L ₁In parallel with " PTC ", L ₂T is in parallel with controller; Then, " PTC " is connected into controller T and connects.When connecting switch, power supply is powered to " PTC " heating by temperature controller, at this moment display lamp L ₁Bright, L ₂Go out.When temperature in the cabinet arrived 125 ℃, temperature controller was cut off the electricity supply and is no longer powered, at this moment L ₁Go out L ₂Bright.

Because " PTC " heating has the automatic constant-temperature function, so controller T also can use time controller instead.Time can be set, and cuts off the electricity supply when arriving the fixed time.

If small fan has been installed in the disinfection cabinet, then can fan electromotor M is in parallel with " PTC ".Shown in Fig. 3 (b).

The utlity model has the advantages such as quick heating, life-span length, use safety.
