Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, and in particular to a refrigeration appliance and a control method. Background Art

[0002] The insulation technology of household refrigeration appliances is the key technology to ensure the stability of the internal temperature of the refrigerator and reduce the loss of cold. Due to the aging or damage of the door seal, frequent opening and closing of the door, improper temperature control settings and other problems, the insulation effect of the refrigeration appliance will become worse and worse over time. Common refrigerator insulation technologies such as multi-layer insulation materials, smart door seals, double-layer door design, etc. are expensive and cannot effectively reduce the loss of cold in the refrigerator door, seriously affecting the energy efficiency and preservation effect of the refrigerator.

[0003] Wind pressure insulation is a technology in building and equipment design that aims to improve the insulation effect by utilizing wind pressure. Wind pressure insulation design can reduce heat conduction by forming an airflow path, using natural wind pressure or mechanical ventilation system to generate airflow, taking away the heat from the surface of the building or equipment. This method not only helps to reduce the temperature inside the building, but also reduces the load of the air conditioning system, achieving the effect of energy saving and emission reduction. Wind curtain insulation is a technology that uses air curtains (also called wind curtain machines) to isolate external cold air or hot air from entering the indoor space, thereby achieving the insulation effect. Wind curtain machines are usually installed in foyers, store entrances, industrial gates, etc., and form an "air barrier" through high-speed airflow to prevent direct exchange of indoor and outdoor air. Wind curtain insulation can isolate the exchange of hot and cold air, maintain indoor temperature stability, reduce equipment load, reduce energy consumption, and prevent external dust and pollutants from entering. Wind curtain products are suitable for commercial buildings, industrial plants, supermarkets, restaurants and other places. Wind curtain technology can effectively improve the insulation effect, but it is less used in household refrigeration appliances and is not highly integrated with the refrigeration system.

[0004] Therefore, the prior art has the problem that the refrigeration effect of the refrigerator compartment of the household refrigeration appliance is not good. Summary of the invention

[0081] Specifically, the first air guiding surface 211 and the second air guiding surface 212 are arc-shaped surfaces respectively, so that the airflow flowing out of the air outlet 22 can flow evenly from both sides of the accommodating cavity 11, so that the cooling in the accommodating cavity 11 is uniform.

[0082] In the refrigeration appliance of this embodiment, see Figures 16 to 18 The refrigeration mask 2 includes an air guide column 3, which is located between the first air guide surface 211 and the second air guide surface 212, and the air guide column 3 is protruding from the air guide surface 21.

[0083] With the above arrangement, the air guide column 3 serves as a structural reinforcement of the refrigeration mask 2 and plays a supporting role. In addition, the temperature compensation air outlet provided on the air guide column 3 can play a compensating role when the temperature of the refrigeration chamber differs too much from the set value.

[0084] See also Figures 16 to 18 In the refrigeration appliance of this embodiment, the air outlet 22 includes a first air outlet 221 and a second air outlet 222 ; the first air outlet 221 is arranged on the air guide surface 21 , and the second air outlet 222 is arranged on the air guide column 3 .

[0089] In the refrigeration appliance of this embodiment, see Fig.16 The connection surface 33 and the first column surface 31 have a first chamfered surface 34 at their connection locations; and / or the connection surface 33 and the second column surface 32 have a second chamfered surface 35 at their connection locations.

[0090] With the above arrangement, the first chamfered surface 34 and the second chamfered surface 35 can better guide the passing airflow and reduce the airflow resistance.

[0091] In the refrigeration appliance of this embodiment, see Figure 2The refrigeration appliance further comprises a plurality of shelves 4 , which are arranged in the accommodating cavity 11 at intervals along the vertical direction; each of the shelves 4 is provided with an avoidance groove 41 for avoiding the air guide column 3 .

[0092] The air duct mask and the glass shelf are assembled, an opening is set in the middle of the glass shelf, and it is fixed on the bayonet of the air guide column 3 of the air duct mask, which improves the stability of the shelf and prevents the shelf from being deformed or even broken due to the accumulation of heavy objects.

[0093] In the refrigeration appliance of this embodiment, see Figures 2 to 6 The refrigeration appliance further includes an air curtain device 5, which is used to create an air curtain to isolate the airflow in the accommodating cavity 11.

[0094] The design of the air curtain device 5 isolates the hot air and harmful substances in the environment through the air curtain pressure, minimizes the heat loss when the refrigerator door is opened, and improves the preservation effect.

[0095] In the refrigeration appliance of this embodiment, there are multiple air outlets 22, and the multiple air outlets 22 are arranged at intervals in the vertical direction; and / or the temperature detection module includes multiple temperature sensors, and the multiple temperature sensors are arranged at different positions of the accommodating cavity 11.

[0096] By adopting the above arrangement, the temperature of different areas of the accommodating chamber 11 can be adjusted in a targeted manner, thereby improving the refrigeration efficiency.

[0098] The above method can effectively prevent the temperature in the containing cavity 11 from being too high, thereby ensuring the freshness of the food.

[0099] In the control method of this embodiment, see Fig.23 , set temperature sensors at different positions in the accommodating chamber 11; determine whether at least one of the temperatures of the various areas in the accommodating chamber 11 corresponding to each temperature sensor is greater than a threshold; if so, calculate the cooling capacity required for each area; and adjust the state of the airflow out of each air outlet 22 corresponding to each area. In this way, the temperature of different areas of the accommodating chamber 11 can be adjusted in a targeted manner, thereby improving the cooling efficiency.

[0102] By adopting the above method, it is ensured that when the door body 10 is closed, the temperature in the accommodating chamber 11 is appropriate, and when the door body 10 is opened, the temperature inside the accommodating chamber 11 is effectively kept from diffusing.

[0103] The refrigeration appliance of this embodiment can improve the refrigeration air circulation mode of the refrigeration appliance, avoid the large amount of cold loss from the door body during the door opening and closing process, and can improve the refrigeration effect and thermal insulation performance of the refrigeration appliance. The specific implementation method is as follows:

[0104] When the doors of the refrigeration appliance are closed, the air curtain devices 5 are silent, and the air outlets of the air curtains face the cabinet 1. When a door of the refrigeration appliance is opened, the air curtain device 5 in the corresponding area is started, the air curtain shaft in the air curtain compartment rotates, and the air outlet faces the direction of the door opening, and the fans at both ends are started, and according to the size and time of the door opening, the weight size and angle of each air curtain outlet can be automatically adjusted to the optimal state.

[0105] In common household refrigeration appliances, the refrigeration mask 2 is mostly in a flat shape, and the air duct outlets are set on both sides of the box body 1. In this patent, the refrigeration mask 2 is designed as an arc surface, which has better guidance for wind circulation. At the same time, multiple air outlets 22 are set on the mask corresponding to the main air duct and the shelf 4 position to facilitate the rapid dissipation of cold in the box body 1, and a temperature compensation air outlet is set in the air guide column 3 of the refrigeration mask 2. According to the temperature changes of various areas in the box body 1, if the temperature of a specific area differs from the set temperature value by more than a threshold, the temperature compensation program of the area is started. At the same time, the shelf 4 is opened near the air guide column 3 of the refrigeration mask 2, and the air guide column 3 of the refrigeration mask 2 is set with a fixed buckle corresponding to each layer of the shelf 4, which can prevent the shelf 4 from being deformed or even broken when heavy objects are placed.

[0106] When the door of the refrigeration appliance is open, the air curtain device 5 can effectively isolate the hot air in the environment from entering the space of the box 1, reduce the heat loss of the box 1, and thus improve the energy efficiency ratio of the refrigeration appliance. At the same time, the air curtain can also effectively prevent dust and pollutants in the environment from entering the box 1, and avoid excessive harmful bacteria in the box space causing food spoilage. In addition, the air curtain device 5 can also effectively prevent water droplets from condensing near the door during the operation of the refrigeration appliance, thereby improving the user experience and anti-condensation effect. When the door of the refrigeration appliance is closed, each temperature sensor in the cold storage room detects the real-time temperature of the corresponding area, and timely compensates the cold when the temperature is lower than the threshold, which can effectively improve the refrigeration effect and reduce energy consumption.
