Abstract
A constant-temperature display cabinet comprises a cabinet body, wherein air passages are arranged on one side of the cabinet body; refrigeration parts of a heating device and a refrigerating device are arranged in the air passages; the air passages are provided with return air inlets and air outlets which are communicated with the inside of the cabinet body; a blower and a temperature controller are arranged in the cabinet body; and the blower is arranged near at least one part in the air passages, the return air inlets or the air outlets. Since air passage baffles are arranged on one side of the cabinet body so as to form the air passages, the heating device and the refrigerating device are arranged in the air passages and the blower operates to form the air convection, the hot air or the cold air can be delivered to other places of the cabinet body; and the temperature controller the mode of heating or refrigerating according to the environmental temperature, so that the temperature in the cabinet body is constant, and the constant temperature of the environment, in which exhibits are located, is ensured.
Description
Technical field
The utility model relates to shows the articles for use field, especially relates to a kind of showcase.
Background technology
Showcase is usually used in showing food, historical relic, cosmetics etc., and some showpieces require lessly to showcase, but for some historical relic or food, they require showcase can remain in certain temperature range.Therefore, the room conditioning of some showcases by the room, place comes the temperature in the indirect regulation showcase, but this adjusting is very unstable, because residing position of showcase and showcase inner air and outer air mobility status are difficult to meet the demands, therefore this adjusting is difficult to satisfy the demand.
The utility model content
The purpose of this utility model is to provide a kind of showcase, and showpiece is in the environment of a steady temperature.
The technical solution of the utility model is:
A kind of constant temperature showcase comprises cabinet, and described cabinet one side is provided with the air channel, is provided with the refrigeration part of heater and refrigerating plant in the air channel, and described air channel also is provided with return air inlet and air outlet and cabinet internal communication, is provided with blower fan and temperature controller in cabinet.
Described blower fan is arranged in the air channel, near at least one place in return air inlet or the air outlet.
Described temperature controller is located near the return air inlet.
In cabinet, be horizontally arranged with dividing plate, cabinet is divided into two parts up and down, described refrigeration part is an evaporimeter, described refrigerating plant comprises compressor, evaporimeter, condenser and the blower fan thereof that is connected by refrigeration pipe, wherein compressor, condenser and blower fan thereof all are arranged on the latter half of cabinet, and evaporimeter is located in the air channel.
Described heater comprises PTC sheet and fin, and the PTC sheet is sealed in the middle of the fin, and PTC sheet one side is connected with temperature limiter.
The opposite side of described PTC sheet also is connected with thermal cut-off.
Described return air inlet and air outlet are provided with uniform aperture.
The utility model forms the air channel by air channel barrier is set in cabinet one side, and heater and refrigerating plant are set in the air channel, and forms convection current by the blower fan running, and hot-air or cold air are delivered to other place of cabinet after through the air channel; Temperature controller is just controlled according to environment temperature and is heated or freeze, and makes the temperature constant in the cabinet, guarantees the temperature of showpiece environment of living in.Cabinet is made by expanded material, and adiabatic heat-insulation has reduced the energy loss of cabinet.Blower fan is obliquely installed, helps the circulation of air-flow in the air channel, make that temperature is suitable in the cabinet everywhere.The element cost of the utility model use is low, and lower with respect to its whole cost of other constant temperature showcase, structure is simpler, adopts control automatically to make that use is also more convenient simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of heater of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises cabinet 8, and cabinet 8 adopts expanded material, adiabatic heat-insulation.Cabinet 8 comprises dividing plate 15, and dividing plate 15 is divided into two parts up and down at cabinet 8 bottom horizontally sets, and the right side of cabinet 8 the first half is rotatably connected to glass door 10.Position near left side cabinet wall in cabinet vertically is provided with air channel barrier 5, the two ends up and down of air channel barrier 5 are fixedly connected on the top board and dividing plate 15 of cabinet 8, formed air channel 1 between air channel barrier 5 and the left side wall, be provided with the evaporimeter 4 of refrigerating plant in air channel 1, evaporimeter 4 vertically is provided with and is parallel with air channel barrier 5.Also fixedly install having heaters 6 on the left side cabinet wall of air channel 1 inner cabinet 8, heater 6 is positioned at the upside of evaporimeter 4.Other parts of refrigerating plant as: compressor 16, condenser 17, condenser fan 18 and throttling arrangement etc. are installed in the latter half of cabinet 8, promptly are positioned at dividing plate 15 times.The setting that is tilted to the right at 45 of the first half of air channel barrier 5 and cabinet 8 top boards, 8 pairs of cabinets should have denation, tilt 45 ° blower fan 7 is installed in the prominence of cabinet 8, the direction of blower fan 7 is vertical with the air channel barrier at this place 5, and corresponding blower fan 7 positions are provided with return air inlet 2 on air channel barrier 5.On near the cabinet the return air inlet 28, be provided with temperature controller 9, be used to detect in-cabinet temperature and whether meet the requirements.Downside at air channel barrier 5 is provided with air outlet 3, and return air inlet 2 and air outlet 3 are provided with uniform aperture.
As shown in Figure 2, heater 6 comprises surface insulation type PTC sheet 12 and fin 13, and PTC sheet 12 is sealed in the fin 13, is fixedly connected with thermal cut-off 11 in PTC sheet 12 left sides, is used to protect PTC sheet 12 not to be damaged; Be fixedly connected with temperature limiter 14 on PTC sheet 12 right sides, too high in order to the restriction heating-up temperature to prevent in-cabinet temperature.
When in-cabinet temperature surpasses design temperature, during such as summer, temperature controller 9 actions, start refrigerating plant, blower fan 7 work simultaneously, the Hot air quilt blower fan 7 in the cabinet on 1 right side, air channel sucks from return air inlet 2, through evaporimeter 4, evaporimeter 4 will carry out heat exchange with air, cooled air through air channel 1 and air outlet 3 get back to again in the cabinet that enters into 1 right side, air channel.
When in-cabinet temperature is lower than design temperature, during such as winter, temperature controller 9 actions start heater 6,12 heatings of PTC sheet, and by fin 13 heat is distributed, blower fan 7 runnings are sent near the hot-airs the heater 6 into other place in the cabinet.When heating-up temperature was too high, temperature limiter 14 sends signal quit work PTC sheet 12, prevents that in-cabinet temperature is too high.When temperature controller 9 records in-cabinet temperature above design temperature, can send control signal heater 6 is quit work.
Should be noted that at last heater 6 in the utility model also can adopt the heater of other type; Refrigerating plant can adopt electric refrigerating plant, and does not need to use compressor 16, condenser 17, condenser fan 18, evaporimeter 4 and throttling arrangement, thereby saves the space of cabinet 8 bottoms, reduces the volume of cabinet 8; Blower fan 7 also can be located in the air channel 1 or near the air outlet 3; These approximate variations all drop within the protection domain of the present utility model.
