Detailed Description
The present invention will be described in detail below with reference to embodiments shown in the drawings. The present invention is not limited to the embodiment, and structural, methodological, or functional changes made by one of ordinary skill in the art according to the embodiment are included in the scope of the present invention.
Referring to fig. 1 to 3, a refrigerator with an air curtain function according to the present invention is shown, and first, an X axis is defined as a front-back direction, a Y axis is defined as a left-right direction (also referred to as a transverse direction), and a Z axis is defined as an up-down direction, the refrigerator is a vertical air-cooled refrigerator, the refrigerator includes a cabinet body 1 and a door body 2, a plurality of shelves 3 are horizontally disposed in the cabinet body 1 at intervals in parallel along the up-down direction, the shelves 3 are in a grid structure so that cool air can freely flow along the up-down direction, and it is ensured that the temperature in the cabinet body 1 is uniform, in this embodiment, the shelves 3 are steel wire shelves.
Referring to fig. 1 to 3, a plurality of infrared distance measuring sensors 11, a plurality of air doors 12 correspondingly matched with the infrared distance measuring sensors 11, an evaporation fan 13 and an evaporator 14 are sequentially arranged on the top of the cabinet body 1 along the front-rear direction, the plurality of air doors 12 are mutually adjacent and are connected end to enclose the periphery of the evaporation fan 13 in an arc shape, so that the air doors 12 and the evaporation fan 13 generate air flows which conveniently and smoothly enter the air doors 12, the refrigerator has a plurality of first air outlets 15 and a second air outlet 16 respectively arranged in front of and behind the evaporation fan 13 and an air return inlet 17 arranged below the evaporation fan 13, the plurality of infrared distance measuring sensors 11 are arranged along the transverse direction, the first air outlets 15 are arranged between the infrared distance measuring sensors 11 and the air doors 12 along the transverse direction and are in one-to-one correspondence with the infrared distance measuring sensors 11, each first air outlet 15 corresponds to each air door 12 one by one through a cold quantity channel.
The second air outlet 16 is located the rear side of evaporator 14, evaporator 14 below is equipped with and is used for acceping when the liquid water that produces when evaporator 14 defrosts is received to water receiver 18, the freezer has and forms the wind channel board 19 of first air outlet 15, wind channel board 19 is including the slope 191 that is located the front side and certainly horizontal part 192 that the slope 191 below level extended, first air outlet 15 is formed in slope 191, air door 12 set up in on the horizontal part 192, just air door 12 clamp is located the roof of cabinet body 1 with between the horizontal part 192, horizontal part 192 with form between the water receiver 18 return air inlet 17, so evaporation fan 13 can be from the middle air outlet of induced draft both sides. The evaporation fan 13 is a centrifugal fan 13, when the door body 2 is closed, the air door 12 is closed, and a refrigeration cycle is formed by the air return opening 17 and the second air outlet 16.
The freezer still includes according to infrared distance measurement sensor 11's signal conditioning the main control unit of the aperture size of air door 12, main control unit corresponds according to sensing distance and sensing area regulation in the sensing area the aperture size of air door 12, simultaneously main control unit still can be according to infrared distance measurement sensor 11's sensing distance is adjusted evaporation fan 13's rotational speed.
The refrigerator with the air curtain function has two working modes, firstly, when the door body 2 is opened, the air doors 12 are all opened, the evaporation fan 13 generates an air curtain from the first air outlet 15 through the air doors 12 to isolate the interference of the external temperature to the internal temperature of the refrigerator, at the moment, each infrared distance measuring sensor 11 downwards emits a light beam to form an induction light curtain, each light beam is not crossed, and each infrared distance measuring sensor corresponds to each air door 12. When a user stretches his hand to pick and place an article, part of the light curtain contacts with the user, the infrared distance measuring sensor 11 corresponding to the part of the light curtain can measure the distance between the hand (hereinafter referred to as the hand) of the user and the infrared distance measuring sensor 11, the infrared distance measuring sensor 11 is close to the first air outlet 15, the distance is equivalent to the distance between the hand and the first air outlet 15, the main control unit adjusts the opening degree of the air door 12 corresponding to the infrared distance measuring sensor 11 which monitors the signal according to the distance, when the distance is farther, the opening degree of the air door 12 is larger, when the distance is closer, the opening degree of the air door 12 is smaller, and the other part of the light curtain does not contact with the user, namely, the infrared distance measuring sensor 11 of the other part does not identify the user, so the opening degree of the air door 12 corresponding to the other part of the light curtain is kept unchanged, not only guarantee that the people hand is not blown by cold wind and hinder, improve user's comfort level, still keep in the region that the staff was not sensed moreover the unchangeable external temperature of effective isolation of aperture of air door 12 thereby realizes piecemeal and local control to the air curtain, and then avoids external temperature to the at utmost right the influence of temperature in the freezer reduces the temperature fluctuation.
Second, each infrared distance measuring sensor 11 transmission beam and intercrossing form response light curtain net, stretch out the hand when putting article as the user can by the light curtain net responds to, the main control unit according to the people hand with the distance of first air outlet 15 is adjusted evaporation fan 13's rotational speed is blown in order to avoid the staff to be hindered by cold wind, improves user comfort.
In summary, the freezer with the air curtain function of the invention can realize the blocking and local control of the air curtain by arranging the infrared distance measuring sensor 11 and the air door 12 on the cabinet body 1 correspondingly and adjusting the opening of the air door 12 according to the distance and the position between the hand and the first air outlet 15 through the main control unit, thereby not only ensuring that the hand is not blown by cold air, but also keeping the opening of the air door unchanged and effectively isolating the outside temperature in the area where the hand is not sensed, thereby avoiding the influence of the outside temperature on the temperature in the freezer to the maximum extent and reducing the temperature fluctuation. The main control unit can also adjust the rotating speed of the evaporation fan 13 to prevent hands from being blown and hurt, and the comfort of a user is improved.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
