Technical Field

The invention relates to the technical field of smart homes and household appliances, in particular to a kitchen cooling refrigerator.

Background

Cooking in a kitchen in summer is a life pain point, because other spaces of a house can be cooled through an air conditioner (including product forms of a central air conditioner, an on-hook machine, a cabinet machine and the like), but due to the space particularity of the kitchen: the gas operation is to keep indoor ventilation to avoid oxygen deficiency hidden trouble, so that the air conditioner, a product based on heat exchange design of a relatively closed space, is difficult to be applied to a kitchen at present. Even if some users install the air conditioner into a kitchen through decoration design, the practical problems that the energy consumption of the air conditioner is increased due to air circulation, the oil smoke of the kitchen is heavy and the like can be found. The products such as the super-cool air heater are only installed on a fan of a suspended ceiling, have limited cooling effect on a kitchen and have the problem that the air is blown to flames to influence the control of the duration and degree of heating.

The technical principles of refrigerators and air conditioners are connected, and heat conversion is realized by circulating refrigerant between an evaporator and a condenser. There have therefore been several patents which propose solutions for refrigerators and air-conditioning units, the prior art solutions mainly focusing on two categories: one is that the integration of the refrigerator and the air conditioner is realized by integrating an outdoor unit, wherein the key is a parallel loop, the flow direction of a refrigerant (independent air-conditioning refrigeration, independent refrigerator refrigeration, simultaneous air-conditioning and refrigerator refrigeration) is controlled by a valve, and the circuit optimization is performed on the basis (the refrigeration load of the air conditioner is utilized for defrosting the refrigerator, the heating loop of the air conditioner is controlled, and the energy efficiency of a heat extraction system is improved); the other type does not have an outdoor unit, and adopts a cold accumulation device to blow across the surface of the ice block through an air duct in order to avoid cold load generated in the air conditioning process.

In an actual life scene, a kitchen can reach a high temperature of 40 ℃ when being heated and cooked in summer, but the kitchen does not feel particularly cold in winter and is provided with equipment such as a heater, so that the scheme of the integrated machine is likely to be idle in winter, and the cold storage scheme cannot actually reduce the indoor temperature.

Disclosure of Invention

The invention aims to solve the problems and provide a kitchen cooling refrigerator, and provides a refrigerator which does not need an outdoor unit and can realize air cooling through a refrigerant, and meanwhile, the extra volume of the appearance of the refrigerator is not increased; the refrigerator can provide an indoor cooling function during cooking, and the refrigerator is still a refrigerator in appearance and has no extra air-conditioning volume.

The invention realizes the purpose through the following technical scheme:

a kitchen cooling refrigerator comprises a refrigerator refrigeration loop, an air conditioner refrigeration loop and an air circulation loop;

the refrigerator refrigeration loop comprises a refrigerator evaporator and a refrigerator condenser, the refrigerator evaporator is arranged at the back of the refrigerator body, the refrigerator condenser is arranged at two sides of the refrigerator body, and heat is dissipated through the two sides of the refrigerator body;

the air conditioner refrigeration loop comprises an air conditioner evaporator, an air conditioner condenser and an ice-water conversion device, ice is converted into water after heat is absorbed, and the loop is started to reverse when the air conditioner is idle, so that the water is converted into ice again;

the air circulation loop comprises an air inlet grid, a fan, an air channel and an air outlet gap, and air cooling is realized through heat exchange with the air conditioning evaporator.

The refrigerator further comprises a refrigerator body, a refrigerator door body, a refrigerator drawer, an air inlet grid, a compressor, a fan, an air conditioner evaporator, an air conditioner condenser and an ice-water conversion device which are arranged at the bottom of the refrigerator body, the refrigerator evaporator arranged at the back of the refrigerator body, the refrigerator condensers arranged at two sides of the refrigerator body, an air channel formed between a shell and an inner chamber of the refrigerator body, an air outlet gap is arranged on an outer frame of the refrigerator body, and the inner chamber of the refrigerator body and the ice-water conversion device are both provided with heat insulation layers.

The air duct is in contact with the evaporator to realize air conditioning refrigeration, so that the room temperature is reduced; the ice-water conversion device is used for absorbing the cold load in the refrigeration process of the air conditioner, so that the heat cannot be exchanged into the room when the air conditioner is used, otherwise, the energy is offset if the air conditioner does not have an outdoor unit and cools the room while radiating the heat. In the scheme, the house layout in the existing market is considered, a refrigerator mode with an air conditioning function is adopted, and the refrigerator mode is not an all-in-one machine integrating the air conditioning function and the refrigerator function, because the outdoor unit of the all-in-one machine is not practical for the current commodity room, and a space for placing the outdoor unit in a kitchen is not supported by a plurality of districts. The refrigerator with the air conditioning function is realized on the premise of no outdoor unit, the key problem is to solve the cold load conversion during the refrigeration of the air conditioner, and the scheme is realized through an ice-water device.

The further scheme is that when the air conditioner is idle, the loop is started to rotate reversely, the refrigerator evaporator and the refrigerator condenser are replaced, water is converted into ice again, the ice is reserved for the next use of the air conditioner, and the generated heat is dissipated from the bottom of the refrigerator. This is the reverse heat exchange process, and is assumed to be completed within four hours, and considering that in real life, the door of the kitchen room may be opened to allow greater air circulation with other rooms after meal is completed, and this process will raise the temperature of the room to less than 0.1 ° for a 100 square residence, but if the other rooms are turned on, the actual feeling of this heat dissipation is negligible.

The further proposal is that the air inlet grid can regularly replace the filter screen, thus solving the problem of oil smoke adsorption of the device in the kitchen environment

Considering the influence of the kitchen environment wind speed on the flame, the wind channel wind outlet runs in a natural breeze state below 0.5m/s, and the wind outlet is hidden in the refrigerator outer frame, so that the whole refrigerator is converted into a bladeless fan. The noise generated by the slow wind is relatively small, and the surface heat dissipation effect caused by the air flow can also make people in the kitchen feel cooler.

The invention has the beneficial effects that:

the domestic kitchen area is required to be not less than 5 square at least, and if the kitchen area is considered to be 10 square and medium-sized, the floor height is 2.7 meters, and the air volume is about 27m³When the temperature is reduced from 40 ℃ in summer to the environment-friendly temperature of about 26 ℃, the generated heat is absorbed by ice blocks with zero degrees centigrade and converted into water in a room temperature state, and the amount of the generated heat is about 1L. The air conditioner can obviously reduce the room temperature after about 5 minutes after being started to operate, the air temperature can be kept for 1-2 hours in other closed rooms, but the kitchen environment is more open and is in a natural circulation state of air, and the indoor air can be replaced generally within about 30 minutes, so that the heat exchange of the air conditioner is performed for about four times assuming that a meal is prepared in the kitchen for two hours, and the corresponding amount of ice water can sufficiently absorb the generated cold load within about 4L. Assuming that the floor area of the refrigerator is about 0.5 square, the ice layer needs to reach 8mm, and no obvious change is brought to the appearance of the refrigerator. Considering that the outdoor air temperature is generally lower than 40 degrees and some heat is also removed during ventilation, the actual amount of ice water should be lower than the above estimate.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.

In any embodiment, as shown in fig. 1-3, a kitchen cooling refrigerator of the present invention includes a refrigerator cooling circuit, an air conditioner cooling circuit, and an air circulation circuit;

the refrigerator refrigeration loop comprises a refrigerator evaporator and a refrigerator condenser, the refrigerator evaporator is arranged at the back of the refrigerator body, the refrigerator condenser is arranged at two sides of the refrigerator body, and heat is dissipated through the two sides of the refrigerator body;

the air conditioner refrigeration loop comprises an air conditioner evaporator, an air conditioner condenser and an ice-water conversion device, ice is converted into water after heat is absorbed, and the loop is started to reverse when the air conditioner is idle, so that the water is converted into ice again;

the air circulation loop comprises an air inlet grid, a fan, an air channel and an air outlet gap, and air cooling is realized through heat exchange with the air conditioning evaporator.

The compressor controls the refrigerant to flow to two loops of the refrigerator evaporator-refrigerator condenser and the air conditioner evaporator-air conditioner condenser respectively to form the parallel working logic of the refrigerator and the air conditioner. The operation logic of the refrigerator is not particularly described, and the operation logic of the air conditioner is as follows.

When the air conditioner function is started, the fan is started, and the opening valve of the compressor refrigerant flowing to the air conditioner evaporator and the air conditioner condenser is opened. The fan forms positive and negative airflow pressure under the centrifugal action, air in a kitchen enters the air duct after being filtered through the air inlet grids at the bottom of the box body, the air conditioner evaporator is in direct contact with the upper layer of the air duct, the air is cooled by absorbing heat, the cooled air continues to move upwards under the action of the fan and is blown out from air outlet gaps (not shown in the figure) at the top and two sides of the box body, and the air outlet speed can be controlled through the fan to form breeze below 0.5 m/s. The process of heat exchange between air and the evaporator of the air conditioner realizes the cooling of indoor air.

Meanwhile, the ice-water device is positioned on the upper layer of the air conditioner condenser and is in direct contact with the air conditioner condenser, the ice-water device absorbs heat of the air conditioner condenser to convert ice into water in a room temperature state, the process of heat exchange between the ice-water device and the air conditioner condenser is realized, cold load conversion during air conditioner refrigeration is realized, and indoor air only obtains cooling benefits.

When the air conditioner function is closed, the fan is not operated, the return valve of the refrigerant of the compressor is opened, the flow direction of the refrigerant between the air conditioner evaporator and the air conditioner condenser is replaced, and therefore the functions of the air conditioner evaporator and the air conditioner condenser are also replaced mutually. The structure of an air duct, an air conditioner evaporator, an air conditioner condenser and an ice water device is replaced by the structure of an air duct, an air conditioner condenser, an air conditioner evaporator and an ice water device from bottom to top. The air conditioner evaporator which is positioned at the lower layer of the ice water device and is in direct contact with the ice water device absorbs heat to convert water into ice again, and the heat of the air conditioner condenser is dissipated from the bottom of the box body through the air duct at the lower layer.

When the air conditioning function is used in a kitchen, the cooling load of the air cooling is absorbed by the ice-water device, but when the air conditioner is idle, the water is converted into ice to release heat to the air, which does not mean that the indoor air conditioning is useless without the outdoor unit. Due to the fact that the specific scene that the kitchen is used or not used is considered, the air cooling effect can be obviously sensed, the air heating effect can be ignored, and the experience of cooking in the kitchen in summer can be improved.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims. It should be noted that the various technical features described in the above embodiments can be combined in any suitable manner without contradiction, and the invention is not described in any way for the possible combinations in order to avoid unnecessary repetition. In addition, any combination of the various embodiments of the present invention is also possible, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
