Definitions

  • the invention relates to a cold rejection, in particular to a frost-resistant device of a refrigerator. Background technique
  • the former works for refrigerated products with a small amount of frosting, but for frozen products, it takes a long time to defrosting each time, so electric heating cream must be used.
  • the electric heating defrosting can heat the evaporator faster and the frost melts, but the electric heating causes an increase in power consumption, and after the defrosting is finished, the excess heat is balanced, and an additional power consumption is required.
  • frost-free products it is more difficult to achieve high levels of energy consumption.
  • a new defrosting scheme uses an electromagnetic varnish to change the frozen refusal liner to iron, the evaporator is entangled normally, and the defrosting needs to be powered off, and the electromagnetic defrosting device is aimed at the inner tank.
  • the electromagnetic heat effect generated causes the temperature of the inner liner to rise, so that the thick water frost layer melts rapidly from the attachment surface, thereby facilitating the falling off.
  • the invention can quickly cure the frost.
  • the frost-resisting device By setting the frost-resisting device on the cold rejection, the frosting amount in the refrigerator can be effectively reduced, and the frost-proof device can be replaced with the cold-rejecting inner and outer portions, thereby replacing the balanced vent hole provided on the door seal on the refrigerator to optimize the product structure.
  • the air entering the freezer can be effectively dried, thereby reducing the amount of frost.
  • a grille on the air hole prevents foreign matter from entering and blocking the nozzle and affecting the effect.
  • a flange is provided at the inner nozzle of the cabinet port connector. Setting the flange prevents the ice from the outside of the air vent from flowing into the pipe.
  • the dehumidification tube and the refusal connection are connected by a hose.
  • hoses of different lengths it is possible to correspond to different types of cold rejections with different wall thicknesses.
  • Figure 2 is a schematic view showing the explosion structure of the dehumidification pipe
  • Figure 3 is a cross-sectional view showing the assembled structure of the dehumidification pipe
  • the dehumidification filter screen 12 is disposed inside the main body near the outer threaded pipe 113 side of the main body 11 1 , and includes: a fixing ring 122 and a dehumidification net main body 121 .
  • the dehumidifying net main body 121 has a stepped cylindrical shape, and the larger diameter side end surface is open, and the smaller diameter side end surface is in the form of a mesh having an array hole, and the fixing ring 122 is sleeved on the outer peripheral surface of the smaller diameter side of the dehumidifying net main body 121.
  • a waterproof gas permeable membrane is provided on the end surface of the mesh, and is fixed to the dehumidification net main body 121 by a fixing ring 122.
  • the connecting housing 22 is provided with an outwardly extending externally threaded tube 222 perpendicular to the upper and lower surfaces of the cylindrical housing 221, and the externally threaded tube 222 is continuously disposed with the cylindrical housing 221,
  • the flange of the externally threaded tube 222 in the cylindrical housing 221 is provided with a flange for preventing water from being brought into the conduit by the external inlet of the air hole 21 11 .
  • An end surface of the cylindrical casing 221 that is sleeved with the tubular portion 212 of the cabinet mounting portion 21 has an inclined shape that matches the inclined end surface of the tubular portion 212.
  • the frost-resistant device 1 is substituted for the vent hole on the door seal, and in the case where the temperature (pressure) fluctuates due to the opening and closing of the compressor in the cold-rejected interior, in the process of performing internal and external gas exchange,
  • the outside of the cabinet enters the gas that is rejected, is dried by the dehumidifying agent, and is blocked by the waterproof gas permeable membrane, so that the gas entering the refusal has a small amount of moisture, and when the gas flows out from the inside of the cabinet to the outside of the cabinet,
  • the moisture in the desiccant is carried away by the dry air from the reject, and the service life of the desiccant can be prolonged.

Abstract

L'invention concerne un réfrigérateur, comprenant un appareil résistant au givre (1), utilisé pour faire communiquer l'intérieur et l'extérieur du réfrigérateur. L'appareil résistant au givre (1) comprend un tube de déshumidification (10) et un agent de déshumidification est introduit dans le tube de déshumidification (10). Le réfrigérateur est en outre doté d'une membrane étanche à l'eau et perméable aux gaz, la membrane étanche à l'eau et perméable aux gaz étant proche d'un côté intérieur d'un corps de réfrigérateur. Une ouverture externe se trouve sur l'arrière d'un boîtier de réfrigérateur (3) du réfrigérateur et une ouverture interne est disposée sur une ouverture de réfrigérateur (2) du réfrigérateur. Un des tubes de déshumidification (10) est connecté à l'ouverture externe et l'autre extrémité est connectée à l'ouverture interne. Un connecteur (30) de boîtier de réfrigérateur doté d'un trou d'air est disposé sur l'ouverture externe et un connecteur (20) d'ouverture de réfrigérateur doté d'un trou d'air est disposé dans l'ouverture interne. Le tube de déshumidification (10) est connecté au connecteur (20) d'ouverture de réfrigérateur par le biais d'un tuyau souple (40). Le réfrigérateur peut efficacement réduire la quantité de givre dans le corps de réfrigérateur, prolonger le cycle de dégivrage pour un utilisateur et réduire la consommation d'énergie.
