Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a vertical beam anti-condensation refrigeration equipment. Background Technology

[0002] With the diversified development of the commercial refrigeration industry, the expansion of fresh food e-commerce and convenience stores is driving a gradual increase in the demand for multi-door display cabinets and a continuous expansion of their application range. The higher the humidity of the environment where the display cabinet equipment is located, the more water vapor the air can hold, making it easier for condensation to occur on the cold surfaces. When condensation accumulates on the vertical beams of the multi-door display cabinet equipment, water can flow into the bottom compressor chamber. Long-term water accumulation can lead to problems such as corrosion of metal parts, aging of insulation materials, and short circuits in electronic components.

[0003] To solve the problem of condensation on the surface of the vertical beam, electric heating is usually used in the vertical beam to prevent surface condensation caused by insulation effect or cold air leakage in high temperature and high humidity environment. However, long-term electric heating will affect the energy consumption of the equipment. Utility Model Content

[0004] To address the energy consumption issue caused by prolonged heating of vertical beams in existing technologies, this invention provides a vertical beam anti-condensation refrigeration device, comprising a cabinet with an inner cavity. At least two doors are hinged to the side walls of the cabinet for opening and closing the inner cavity. A vertical beam is positioned between the doors, and a heating module for heating the beam is installed within it. A temperature sensor for measuring the beam's temperature is located on the underside of the beam, and a temperature and humidity sensor for measuring the current temperature and humidity is installed on the cabinet surface. The heating module, temperature sensor, and temperature and humidity sensor are electrically connected to a controller. The controller controls the opening and closing of the heating module based on the relationship between the dew point temperature and the vertical beam temperature under the current temperature and humidity.

[0005] Specifically, the vertical beam includes an inner beam and an outer cover. The front side of the inner beam is provided with a groove and sliding grooves symmetrically arranged on both sides of the groove. The outer cover is provided with sliding rails on both sides that match the sliding grooves. The sliding rails are assembled into the sliding grooves. The outer cover and the inner beam form an installation cavity at the groove. The heating module is disposed in the installation cavity.

[0007] Specifically, the heating module is fixed to the inside of the outer cover by aluminum foil tape.

[0008] Specifically, the heating module is a heating wire.

[0009] Specifically, the temperature and humidity sensor is located inside the hinge cover of one side of the door.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. The specific implementation of the present utility model will be described in detail below with reference to specific embodiments.

[0021] like Figures 1-4 As shown, this utility model provides a vertical beam anti-condensation refrigeration device, which can be a refrigerator, display cabinet, etc. The refrigeration device includes a cabinet body 1, with an inner cavity inside. At least two doors 2 are hinged to the side walls of the cabinet body 1 for opening and closing the inner cavity. Multiple doors 2 are arranged opposite each other, with vertical beams 3 between them. The vertical beams 3 provide support for the cabinet body 1. Magnetic strips are installed inside the door seals of the doors 2. The vertical beams 3 cooperate with two double-leaf glass doors to achieve airtight insulation inside the cabinet.

[0022] The vertical beam 3 includes an inner beam 4, an outer cover 5, a heating module 6, and a temperature sensor 7. The inner beam 4 has a hollow structure with a groove 8 on its front side and symmetrical sliding grooves 9 on both sides of the groove 8. The inner beam 4 is filled with foam material, which effectively blocks the exchange of heat between the cold air inside the cabinet 1 and the external environment, effectively reducing heat loss. The dense filling of the foam material significantly enhances the overall structural strength and rigidity of the vertical beam 3. The outer cover 5 has slide rails 10 on both sides that match the sliding grooves 9. The outer cover 5 is assembled with the inner beam 4 by inserting it into the sliding groove 9 from one end of the inner beam 4. The outer cover 5 and the inner beam 4 form an installation cavity 11 at the groove 8.

[0023] To prevent insufficient insulation of the vertical beam 3 from causing a drop in its outer surface temperature, or due to a loose seal between the door seal and the vertical beam 3 after the door 2 is closed, allowing cold air from inside the cabinet 1 to diffuse to the vertical beam 3 and cause a drop in its outer surface temperature, a heating module 6 is installed in the mounting cavity 11. The heating module 6 is an electric heating module with a current heating effect, such as a heating wire. The heating module 6 is fixed to the inside of the outer cover 5 using aluminum foil tape, which evenly conducts the heat generated by the heating module 6 to the surface of the outer cover 5. Utilizing the current heating effect of the heating module 6, it is energized to generate heat and evenly conducts the heat to the front surface of the vertical beam 3, maintaining a certain temperature on the front surface of the vertical beam 3 and reducing the possibility of condensation on the surface of the vertical beam 3 in humid environments.

[0024] To reduce energy consumption during the heating process of the door 2, temperature sensors 7 for measuring the temperature of the vertical beam 3 are installed in the vertical beam 3, and temperature and humidity sensors 12 for measuring the current temperature and humidity are installed on the surface of the cabinet 1.

[0025] Temperature sensor 7 is located on the lower side of the outer casing 5. It can be a sensor that converts temperature signals into measurable electromotive force or resistance, such as a thermocouple temperature sensor or a resistance temperature sensor. The cable of temperature sensor 7 is electrically connected to the controller through the mounting cavity 11. Due to the high density of cold air, the temperature inside the cabinet 1 exhibits a distribution characteristic of being higher at the top and lower at the bottom in the vertical direction. When condensation occurs due to cold leakage from the door seal or poor insulation of the vertical beam 3, causing low temperature on the outer surface of the vertical beam 3, the temperature sensor 7 located on the lower side of the vertical beam 3 can more accurately reflect the temperature status of the vertical beam 3. This avoids condensation occurring on the lower side of the vertical beam 3 when the temperature on the upper side of the vertical beam 3 is higher and kept dry, while the temperature on the lower side of the vertical beam 3 is already below the dew point temperature. Temperature sensor 7 is preferably located within 40cm of the lower end of the vertical beam 3.

[0026] The temperature and humidity sensor 12 is located on the outside of cabinet 1, inside the hinge cover of one side door 2, and is used to measure the current temperature and humidity of the external environment. The sensor's placement within the hinge cover prevents cold leakage from door 2 or cabinet 1 from affecting its detection, ensuring accuracy. The sensor 12 is electrically connected to the controller, acquiring feedback electrical signals from ambient temperature and humidity sensors via a connecting cable and converting them into ambient temperature and humidity data.

[0027] The heating module 6 is electrically connected to the controller. The controller controls the opening and closing of the heating module 6 based on the relationship between the dew point temperature under the current temperature and humidity and the temperature of the vertical beam 3. When the temperature of the vertical beam 3 is lower than the dew point temperature under the current temperature and humidity, the controller controls the heating module 6 to start and heat the vertical beam 3. When the temperature of the vertical beam 3 is higher than the dew point temperature, the controller stops the heating module 6. This achieves precise control of the surface temperature of the vertical beam 3, avoiding excessively high surface temperature of the vertical beam 3 due to long-term heating operation, which would affect the cooling performance. At the same time, the periodic control of the heating module 6 can effectively reduce power consumption and improve the energy efficiency of the whole machine compared to the constant power-on state.

[0028] Furthermore, in some embodiments, a collection mechanism is also provided on the lower side of the vertical beam 3 to collect condensation generated due to failure to heat in time. A compressor compartment 13 is provided at the bottom of the cabinet 1, and an end cover 14 is provided at the front end of the compressor compartment 13. A water collection trough 15 is provided in the end cover 14 below the vertical beam 3. A through hole is provided at the bottom of the water collection trough 15, and a drain pipe 16 with an interference fit and fixedly connected to the water collection trough 15 is provided at the through hole. The drain pipe 16 drains the condensation collected in the water collection trough 15 to the water receiving tray 17 located in the compressor compartment 13. A compressor, a condenser, and the water receiving tray 17 are provided inside the compressor compartment 13. The condenser is equipped with a condensing fan. An air inlet is provided on the rear side of the compressor compartment 13, and an air outlet is provided on the front side. Air drawn in from the air inlet is heated by the compressor and condenser, accelerating the evaporation of moisture in the water receiving tray 17. If condensation occurs due to failure to heat in time, the condensation drips down the vertical beam 3 into the water collection tank 15 and is then guided through the drainage pipe 16 to the water receiving tray 17 to collect the condensation, thus preventing problems such as metal parts corrosion, insulation material aging, and electronic component short circuit failure caused by water flowing into the compressor chamber 13.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
