Detailed Description
The air guide and outlet structure of the half-height refrigerated display case shown in the attached fig. 1-2 is an improvement of the air guide and outlet structure of the common half-height refrigerated display case which is generally applicable in the past.
The invention is further described below and embodiments of the invention are given in conjunction with the drawings of the specification.
This kind of wind-guiding air-out structure of half high-type refrigerated display case includes: set up at the wind channel 11 at the cabinet body inner chamber back, set up evaporimeter 14 in the wind channel, set up at 11 lower part cabinet body inner chamber's in wind channel fan 8 and set up the honeycomb wind-guiding mouth 13 that is used for forming the air curtain at wind channel upper portion air outlet, its characterized in that: the upper part of the evaporator 14 is provided with an air duct partition plate 4 which divides the whole air duct 11 into an air duct for conveying condensed air to an upper air outlet and a side air duct which enters the inner cavity of the cabinet body through air guide holes 12 on the inner side wall of the air duct 11; the inner side of the honeycomb air guide opening 13 is provided with an air outlet guide plate 1 which rises from an air duct 11 and is output through the honeycomb air guide opening 13 to form an outer air curtain 9 and an inner air curtain 10 which isolate the goods shelf plate 5 in the cabinet body.
A plurality of lateral guide plates 3 are arranged on one side of the evaporator 14, and the condensed air is guided to laterally move through the air guide holes 12 on the inner side wall and enter the inner cavity of the cabinet body on which the goods shelf plates 5 are arranged.
The air duct partition plate 4 is a right-angle turning plate body, and one side of the air duct partition plate 4 is provided with a support piece 6 and an air duct fixing piece 2 which are fixed on a foaming plate on the back of the cabinet body.
The air guide air outlet structure of the half-height refrigerated display cabinet has the working principle as follows:
the condensation air in the air duct 11 is divided into two paths of condensation air which is upward and towards the inner cavity of the cabinet body by dividing the condensation air in the main air duct 11 into an air duct which conveys the condensation air to an air outlet at the upper part and an air guide hole 12 which guides the condensation air to pass through the air guide hole 12 on the inner side wall of the air duct 11 through the air guide hole 4 which is arranged on the upper part of the evaporator 14, and then the condensation air enters the inner cavity of the cabinet body in which the goods shelf plate 5 is arranged. The upward condensed air forms an inner air curtain and an outer air curtain which play a role of isolation through the air outlet guide plate 1 of the air outlet; the temperature of the outer air curtain is slightly higher due to the influence of the environment, and the temperature of the inner air curtain is slightly lower due to the close proximity of the inner cavity of the cabinet body of the goods shelf plate; the air layer in the space between the inner layer air curtain and the outer layer air curtain just plays a role in isolation; meanwhile, the condensed air directly enters the inner cavity of the cabinet body through the guide plate arranged on the evaporator, so that the temperature in the cabinet can be effectively kept at an ideal 0 ℃.
Above is only the basic embodiment of the utility model that the applicant provided according to the technical scheme of the present invention, and any technical improvement that does not have substantial innovation that technical personnel in this trade make with this innovation scheme should all be regarded as belonging to the protection scope of the utility model.
