Technical Field

The invention relates to the field of hotel refrigerators, in particular to a hotel refrigerator operating at low noise.

Background

The hotel refrigerator is a small refrigerator which is specially used for refrigerating foods such as fruits, beverages, wines and the like in star hotel guest rooms, the existing hotel refrigerator is high in operation noise, the resting quality of guests is reduced, the user experience effect is greatly reduced, and the condition of large-scale popularization is not met.

Disclosure of Invention

The invention mainly aims to provide a hotel refrigerator running at low noise, which can effectively solve the problems in the background technology.

In order to achieve the purpose, the invention adopts the technical scheme that:

the utility model provides a hotel refrigerator of low noise operation, includes box and chamber door, box top surface external fixation has the button panel, and box top surface inside is fixed with the thalposis ware, and box top rear wall is fixed with the scattered cold piece of aluminium, the cold piece that looses of aluminium is connected with the refrigeration chip, be fixed with one set of heat abstractor on the box in the refrigeration chip outside, bottom half outer wall is fixed with main control circuit board.

Preferably, a magnetic sealing ring is arranged at the joint of the box door and the box body, and a handle is fixed on the outer wall of the box door.

Preferably, four buffer foot pads are fixed at four corners of the outer wall of the bottom surface of the box body.

Preferably, the heat dissipation device consists of a heat dissipation box and a fan.

Preferably, the top surface of the heat dissipation box is provided with a filter screen, and the bottom surface of the heat dissipation box is provided with a fan.

Preferably, a protective cover is fixed on the outer side of the main control circuit board.

Compared with the prior art, the invention has the following beneficial effects: the invention reduces the vibration and absorbs the noise in the running process of the refrigerator through the arrangement of four sets of buffering foot pads, the refrigeration is carried out through the refrigeration chip, the cold air is dispersed in the refrigerator body through the aluminum cooling dispersing sheet, the refrigeration purpose is achieved, the refrigeration temperature is monitored through the temperature sensor and is controlled through the main control circuit board, the flow of the air in the cooling box is realized through the fan arranged in the heat dissipation device when the refrigeration chip works, the heat dissipation of the refrigeration chip is facilitated, the refrigeration chip has a temperature running environment, when the silent work or the quick refrigeration is needed, the button on the button panel can be pressed or the remote control operation can be carried out, the input mode is set, the air is sent to the main control circuit board through the signal wire, the low-power operation is forced when the silent work mode is carried out, the refrigeration box still refrigerates, but the refrigeration quantity is smaller, the response rotating speed of the fan is reduced, the power is not correspondingly reduced as in a normal mode along with the reduction of the temperature in the refrigerator, the refrigerator always works in a maximum power mode until the temperature in the refrigerator reaches a set temperature, and then the power is reduced to reach temperature balance.

In the figure: 1. aluminum cooling fins; 2. a temperature sensor; 3. a button panel; 4. a handle; 5. a box door; 6. a buffer foot pad; 7. a box body; 8. a main control circuit board; 9. a shield; 10. a heat sink; 11. a refrigeration chip; 12. filtering with a screen; 13. a heat dissipation box; 14. a fan.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

As shown in fig. 1-2, a hotel refrigerator with low noise operation comprises a box body 7 and a box door 5, a button panel 3 is fixed on the outer portion of the top surface of the box body 7, a temperature sensor 2 is fixed on the inner portion of the top surface of the box body 7, four sets of buffer foot pads 6 are fixed on four corners of the outer wall of the bottom surface of the box body 7, a magnetic seal ring is arranged at the joint of the box door 5 and the box body 7, a handle 4 is fixed on the outer wall of the box door 5, an aluminum cooling fin 1 is fixed on the rear wall of the top of the box body 7, the aluminum cooling fin 1 is connected with a refrigeration chip 11, a set of heat dissipation device 10 is fixed on the box body 7 outside the refrigeration chip 11, the heat dissipation device 10 is composed of a heat dissipation box 13 and a fan 14, a filter screen 12 is arranged on the top surface of the heat dissipation.

The invention is a hotel refrigerator with low noise operation, when in use, the vibration in the refrigerator operation process is weakened and the noise in the refrigerator operation process is absorbed through the arrangement of four sets of buffer foot pads 6, the refrigeration is carried out through the refrigeration chip 11, the cold air is dispersed in the box body 7 through the aluminum cooling fins 1, the refrigeration purpose is achieved, the refrigeration temperature is monitored through the temperature sensor 2 and is controlled through the main control circuit board 8, the air flow in the cooling box 13 is realized through the fan 14 arranged in the cooling device 10 when the refrigeration chip 11 works, the heat dissipation of the refrigeration chip 11 is facilitated, the refrigeration chip 11 has a temperature operation environment, when in mute operation or quick refrigeration, the button on the button panel 3 can be pressed or the manual remote control operation is carried out, or the user can also time the machine, the mode setting is determined and is sent to the main control circuit board 8 through the signal line, in the silent working mode, the low-power operation is forced, the refrigerating box still refrigerates, but the refrigerating capacity is smaller, the fan responds to the reduction of the rotating speed to cause the normal rotating speed to be 30 percent or less, lower noise is generated, in the rapid refrigerating mode, along with the reduction of the temperature in the box, the power does not correspondingly reduce as in the normal mode, the rapid refrigerating mode always works in the maximum power mode until the temperature in the box reaches the set temperature, and then the power is reduced to reach the temperature balance.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
