The utility model adopts following technical scheme:

Box heat pump drying, oven comprise evaporimeter, condenser, compressor, cross valve in casing, chamber door, controller and the heat pump type air conditioning system, and evaporimeter is installed in outside the inner chamber of casing, and condenser is installed on the riser that is arranged in cabinets cavity.

Be provided with a top board with holes and left and right each riser with holes in the cabinets cavity, the top board two ends are connected with left and right riser, and top board, left and right riser, casing diapire, casing rear wall and chamber door constitute drying, baking chamber.

The roof and the sidewall of top board and riser and casing are gapped, constitute gas channel.

Condenser is made of the first module that is connected in parallel and Unit second, is installed in the bottom of left and right riser respectively.

Evaporimeter is installed in the top of casing, and fan is installed in the opposite of evaporimeter.

The top of casing is equipped with centrifugal blower, and the air outlet of centrifugal blower is connected with gas channel.

Offer exhaust outlet on the roof of casing.

Evaporimeter is made of first module, Unit second, Unit the 3rd, first module and Unit second are connected in parallel, and its import links to each other with the outlet of check valve, and outlet links to each other with the import of cross valve, the import of Unit the 3rd links to each other with the outlet of automatic deloading valve, and outlet links to each other with the import of cross valve.

Advantage of the present utility model is:

1, use heat pump techniques, energy-conservation, safety can not make thing burned.

2, condenser is installed in the casing, and condenser constantly dispels the heat, and centrifugal blower is forced the continuous circulation cycle of air in the case, and rate of heat exchange is fast, dry, fast baking, and quality is good.Evaporimeter is contained in outside the casing, and fan is forced the circulation of case outer air over against evaporimeter, and evaporimeter absorbs the air heat, has given full play to the advantage of heat pump techniques.The automatic deloading valve is housed in the circulation cycle of cold-producing medium simultaneously, and the air in the case can constantly be heated like this, thereby obtains higher temperature.

3, evaporimeter, compressor, fan etc. are installed in the top of casing, do not take the box house space, and the case internal volume is relatively large.

The specific embodiment

In conjunction with the accompanying drawings and embodiments the utility model is further described.

Referring to Fig. 1 to Fig. 5, box heat pump drying, oven comprise evaporimeter 5,

condenser

4,12, compressor 7, cross valve 17 in casing 1, chamber door 10, controller 2 and the heat pump type air conditioning system.

Evaporimeter 5 is installed in the top of casing, and fan 6 is installed in the opposite of evaporimeter 5.Fan 6 makes the case outer air evaporimeter of flowing through, shown in the arrow of Fig. 4 middle and upper part, and evaporimeter absorbing environmental heat.Present embodiment evaporimeter 5 is made of first module 51, second unit 52, the 3rd unit 53, the first module 51 and second unit 52 are connected in parallel, its import links to each other with the outlet of check valve 16, outlet links to each other with the import of cross valve 13, the import of the 3rd unit 53 links to each other with the outlet of automatic deloading valve 17, and outlet links to each other with the import of cross valve 13.

Condenser is installed on the riser that is arranged in cabinets cavity.The condenser of present embodiment is made of the first module 4 that is connected in parallel and second unit 12, is installed in the bottom of left and

right riser

3,11 respectively.

Be provided with a top board with holes 9 and left and right each riser with

holes

3,11 in casing 1 inner chamber of present embodiment, the top board two ends are connected with left and right riser, and top board, left and right riser, casing diapire, casing rear wall and chamber door constitute drying, baking chamber.

The roof and the sidewall of top board 9 and

riser

3,11 and casing 1 are gapped, constitute gas channel 20,21.The top of casing 1 is equipped with centrifugal blower 8, the air outlet of centrifugal blower is connected with

gas channel

20,21, centrifugal blower constantly blasts the case outer air in the case, in being heated the dry baking of inflow chamber, condenser rises again, constitute air-flow circulation in the case, shown in arrow among Fig. 3, the article in thermal current drying, the baking box.

Offer exhaust outlet on the roof of casing 1, from then on the moisture content that is dried, toasts out discharge in the hole.

Cold-producing medium flow process in the heat pump type air conditioning system is shown in Fig. 5 solid arrow direction.The refrigerant gas of HTHP from the machine 7 of contracting come out through cross valve 13

enter condenser
