Description
Technical field
The present invention relates to the structure of refrigerator and build adaptation technique field with external wall of house, particularly relating to refrigerator and temperature control method thereof in a kind of wall.
Background technology
The domestic refrigerator of First compression-type refrigeration in the world in 1910 comes out in the U.S., nineteen twenty-five, Sweden developed family expenses absorption refrigerator, the fifties in last century, latter half, Household hot refrigerator started to put into production ... develop into today, refrigerator is classified by refrigeration principle: (1) in the world 91 ~ 95% refrigerator belong to compressor type refrigerator, its refrigeration system is made up of compressor, condenser, device for drying and filtering, capillary (throttling arrangement), evaporimeter; Motor compressor work done, cold-producing medium is flowed in systems in which, the refrigerant vapour of HTHP (more than ten atmospheric pressure) is discharged into the condenser be arranged on outside case shell, dispel the heat there, liquefy, cold-producing medium enters the evaporimeter in refrigerator in liquid form, in evaporimeter, evaporation is gasified and absorbs the heat in refrigerator, makes refrigeration in refrigerator; Cold-producing medium is general freon in the past, because it can damage the ozone layer, eliminated gradually now, use other cold-producing mediums instead, but principle is the same.(2) absorption refrigerator accounts for market 5 percent, forms by generator, rectifier, condenser, evaporimeter, absorber, lime set tank the refrigeration system closed; Be filled with ammonia, water, hydrogen three kinds of components in system, wherein the high steam of ammonia dispels the heat liquefaction in case shell external condenser, and liquid ammonia heat in evaporation gasification, respiratory box in evaporimeter in refrigerator, produces refrigeration.(3) electric heating refrigerator and borne semiconductor refrigerator; It is to PN type semiconductor, passes to direct current, utilizes the pyroelectric effect of semi-conducting material to realize the refrigerator of refrigeration.In addition, chemical refrigerator, electromagnetic oscillation refrigerator, adiabatic demagnetization refrigeration refrigerator, radiation refrigeration refrigerator, solid coolant refrigerator etc. is also had.
If press refrigeration modes (by air circulation mode in the case) classification of refrigerator, direct-cooling type and air-cooled (also known as indirect-cooling) refrigerator can be divided into.Direct cooling refrigerator is by evaporimeter, and in direct respiratory box, heat is lowered the temperature; And air cooling type refrigerator case is built with evaporimeter and fan, fan air-supply, forces case inner air convection, promotes heat in evaporimeter respiratory box, realizes uniform decrease in temperature in case.If press refrigerator purposes (by Storage Requirement) to divide, refrigerating box, household freezer and household refrigerator-freezer can be divided into.Refrigerating box, for storing the food not needing to freeze, sets case temperature scope about 4 DEG C-5 DEG C; Household freezer is suitable for food product refrigeration, and below-18 DEG C, (because of storage, frozen food difference, refrigerator manufacturer difference has different to setting case temperature, but substantially close in refrigerator temperature setting.For above-mentioned setting case temperature during the application discusses).Refrigerator also can, refrigerating capacity, Defrost mode etc. how many by chamber door be classified, and does not repeat one by one.
There are some problems in refrigerator prior art, wherein following 4 important, have much room for improvement:
The first, refrigerator environment temperature concerns energy-conservation.
In order to refrigerator energy-saving, domestic consumers have noticed that refrigerator should be placed in indoor stow away from heat, ventilation shady spot.Brainstrust is then pointed out theoretically; the environment temperature of refrigerator and refrigerator environment temperature height have a direct impact refrigerator power consumption: refrigerator environment temperature raises; refrigerator outwards dispels the heat slowly; the temperature inside the box declines slow; and the cold that outwards scatters and disappears in case is many, keeps the low temperature of setting in case more difficult, cause the refrigerator available machine time to lengthen; downtime shortens, and causes power consumption to increase.General refrigerator experimental data is pointed out, and refrigerator environment temperature often improves 5 degree Celsius, will increase by the power consumption of about 25%.Otherwise other physical conditions are identical and refrigerator environment temperature declines, and refrigerator power consumption is then by corresponding minimizing.But Modern Family's comfort zone about 20 DEG C-25 DEG C, domestic refrigerator is placed in indoor, and refrigerator environment temperature is room temperature, the temperature difference that compared with setting case temperature with refrigerator cold closet plastic or refrigerator freezing case, existence is higher, this higher temperature difference, the power consumption higher with refrigerator concerns.If the room temperature of the environment temperature ratio of refrigerator decreases, refrigerator energy-saving will be realized.
The second, the utilization of cold outdoor air.
If refrigerator is placed on indoor, the room temperature of Modern Family's comfort standard about 20 DEG C-25 DEG C, the environment temperature of indoor environment temperature and refrigerator, should not change; Outdoor environment temperature is see table 1.Table 1 lists the monthly mean temperature of 10 major country cities (comprising largest city or the capital of 5 permanent members of the United Nations and all the other 5 developed countries) annual 12 months in the world.
Annual monthly mean temperature statistical form (degree Celsius) in major country city, ten, table 1. world
It has certain representativeness for quite vast region temperature Change scope in the world.If be one " monthly temperature " with the temperature on average of wherein some moons in some cities, table 1 has been added up 120 " monthly temperature " altogether.Wherein
(1) 116 " monthly temperature ", lower than 25C, accounts for 96.6%;
(2) 104 " monthly temperature ", lower than 20C, account for 86.6%;
(3) 80 " monthly temperature ", lower than 15C, account for 66.6%;
(4) 60 " monthly temperature ", lower than 10C, account for 50%;
(5) 39 " monthly temperature ", lower than 5C, account for 33.3%;
(6) 22 " monthly temperature ", lower than 0C, account for 18.3%.
Visible, in the world immensely territory overwhelming majority time, outdoor environment temperature is lower than indoor environment temperature.
Using cold outdoor air as the refrigeration source of refrigerating equipment, especially in northern area winter, some imaginations were once suggested for many years, were difficult to for various reasons obtain coml extensive use.Need to explore a kind of more simple and easy structure and method, cheaply directly apply this large amount of naturally occurring cold outdoor air and participate in refrigeration for refrigerator.
3rd, refrigerator occupies valuable careat and space.
Refrigerator takies one of maximum household electrical appliance of careat and space, and its front and back also need to retain certain distance with indoor wall or other furniture up and down in addition.In the family room of big and medium-sized cities usable floor area and space increasingly expensive in short supply, both having retained the function of refrigerator, and economized out again the careat occupied by it and space, is expecting of people.
4th, refrigerator is also highfield.
According to expert introduction, be a highfield during refrigerator work, usually maximum with the magnetic field of side on rear side of refrigerator or below release.The electromagnetic wave of the different wave length that refrigerator discharges and frequency has certain influence to the nervous system of people and physiological function; Electromagnetic penetration power is extremely strong, can go deep into deep tissues and organ, make it to suffer damage through body surface.Reducing and avoid refrigerator magnetic field on the impact of human body and infringement, is also one of problem of often considering of people.
People once proposed such-and-such scheme respectively for this reason.
Than if any scheme propose refrigerating equipment to be placed on open air, or to be arranged on window.Although but the housing of refrigerating equipment can use quality material manufacture, exposing year in year out after all outdoorly affects service life; Temperature is suitable for use about refrigerating equipment design temperature, and the food not needing to freeze of temperature is low then refrigerated storage can be frozen, and temperature is high, and more things turn out contrary to one's wishes; Inconvenience accesses food in indoor from refrigerator, or affects indoor lighting sight.
Some schemes propose, with lower wall conduit, cold outdoor air is introduced indoor connection refrigerator, cold air is squeezed into refrigerator by fitted shaft flow fan, pass in case, air after displacement in case is discharged in outdoor air and goes by the blast pipe again through drawing in case under ventilating fan coordinates and another lower wall conduit, circularly cooling like this.This air cooling system has certain length into and out of pipeline, need bore under hole made by wall and manage, and operates simple and direct not.And refrigerator is placed in various problem caused by indoor and unresolved.
Some schemes propose compressor, condenser to separate from the refrigerator that routine is arranged, and are placed in open air, are connected with the refrigerator remainder as indoor set by wall conduit wire, to reduce refrigerator indoor radiating, noise as off-premises station.But this minimizing is very limited, because the device participating in refrigerator heat radiation is not restricted to compressor and condenser, be in fact still placed on the main body of indoor refrigerator, machine chamber, air blast so that air flow guide member etc. are all relevant with refrigerator heat radiation.And some problems that refrigerator is placed in caused by indoor still exist.
Some schemes are also had to propose refrigerator to embed in the depression of wall; Or in embedding kitchen cabinet; Or the partition wall be built between two rooms, not the exterior wall in house, is such as built in the partition wall between kitchen and parlor, refrigerator opposed access door, therefore can accesses food from kitchen and parlor simultaneously.These schemes can make indoor beautifying, save careat space to a certain extent, but in fact refrigerator is also in indoor, and the environment temperature of refrigerator or room temperature, be also difficult to tackle some problem above-mentioned.
In addition, for the impact of refrigerator electromagnetic radiation, expert advice refrigerator is not placed on the place that the people such as parlor often stay, and is placed on storing food when kitchen also will to be avoided when refrigerator work near it as far as possible or avoid in refrigerator work as far as possible; And through conventional dust catcher, the position dusts such as refrigerator radiating tube are sopped up because dust more multiple electromagnetic radiation is larger.But its limited efficiency, for the solution of above-mentioned other problems also without benefiting.

(3) beneficial effect
Beneficial effect of the present invention can from the convenient utilization of refrigerator environment temperature and energy-conservation, cold outdoor air, add indoor usable floor area and space, alleviate the several angle in the several aspect of harm and user, housing developer, refrigerator manufacturers and society in refrigerator magnetic field and inquire into.
1. refrigerator environment temperature and energy-conservation
Comprehensively analyze from the region representated by 10 cities listed by table 1., in usual normal room temperature 20 DEG C-25 DEG C, the monthly temperature of about 86.6%-96.6% lower than room temperature.First analyze the situation of outdoor temperature lower than room temperature at this, at this moment outdoor temperature lower than room temperature in wall refrigerator environment temperature also lower than room temperature.Consider that brainstrust points out that environment temperature (refrigerator environment temperature) height of refrigerator has a direct impact refrigerator power consumption, and experimental data prompting refrigerator environment temperature often improve Celsius 5 degree will increase about 25% power consumption, be placed in indoor conventional refrigerator environment temperature and be room temperature, significantly higher than refrigerator environment space temperature in wall, conventional refrigerator power consumption is namely significantly higher than refrigerator power consumption in wall.Visible, vast region temperature lower than room temperature over a long time in due to refrigerator environment temperature in wall lower than room temperature, therefore present invention achieves refrigerator energy-saving.
Comprehensively analyze from the region representated by 10 cities listed by table 1., the monthly temperature proportion higher than room temperature is very little.In this short-term, even if the temperature longer in other regions is higher than the period of room temperature, in wall, refrigerator environment temperature can keep identical with room temperature.Respectively for high 1.8 meters, wide 0.6 meter of the common vertical refrigerator of one, dark 0.6 meter and one split type exist side by side refrigerating box and high 1.8 meters, wide 1.2 meters of household freezer, dark 0.6 meter, if the physical dimension of its refrigerator environment temperature space than exceed from refrigerator body 10 centimetres, dark 10 centimetres, both sides each wide go out about 5 centimetres, in both walls, the volume of refrigerator environment temperature space is about 0.28 cubic metre and 0.43 cubic metre respectively.Contrast the volume of the ordinary residence about 220 cubic metres of a usable floor area 100 square metres, high 2.2 meters, in both walls, the volume of refrigerator environment temperature space only occupies about 0.1% and 0.2% of residence volume respectively, the volume space of so little by little ratio is made also to keep room temperature, only need to increase little energy consumption, particularly contrast energy-conservation lower than during room temperature of temperature, the total energy consumption in refrigerator is long-time reduces.
2. the convenient utilization of cold outdoor air
In the present invention, in wall cavity rear wall and wall, the spacing at refrigerator rear portion is very short, and be connected to the straight tube of straight-through air inlet between the two, exhausting stub tube often just tens centimeter length, structure is simple, and assembling is easily, easy to utilize.
More than ten atmospheric refrigerant vapours need be entered condenser during conventional refrigerator compressor operating, and continue to circulate in systems in which, acting is many, and power consumption is higher; In wall during the work of refrigerator cold outdoor air refrigeration system, air inlet, blast pipe are short and straight, and fan air blast, exhaust resistance are all very little, and power consumption is little.
When conventional refrigerator is enabled, need empty van test running 2 hours, could stable food after reaching in case and stablizing.The food of heat will cool just can put into case afterwards, otherwise more can increase power consumption.In wall, " refrigeration source " of refrigerator cold outdoor air refrigeration system is a large amount of naturally occurring cold air, refrigerating capacity is large, cooling rate is fast first, therefore when in wall, refrigerator is enabled, without the need to empty van test run then can direct stable food, the food of heat also just need not can put into case after cooling, and directly can put into wall refrigerator food precooling room, herein after the precooling in a moment of cold outdoor air refrigeration system, dump to refrigerator cold closet plastic or household freezer in wall, very micro-on power consumption impact.
3. add indoor usable floor area and space
General refrigerator is placed in indoor, takies a part of indoor usable floor area and the interior space.Still respectively for high 1.8 meters, wide 0.6 meter of the common vertical refrigerator of one, dark 0.6 meter and a kind of body split type exist side by side refrigerating box and high 1.8 meters, wide 1.2 meters of household freezer, dark 0.6 meter, its rear, top and both sides routine reserve the distance of some centimetres, interior architecture area about 0.5 square metre and 1 square metre will be taken respectively, take the interior space about 1 cubic metre and 2 cubic metres respectively.The room rate of modern city house every square metre of construction area is often higher than refrigerator price several times.If refrigerator in use wall, this part occupied indoor usable floor area and the interior space just can save out.
4. alleviate the harm in refrigerator magnetic field
Refrigerator is moved to hole in wall by the present invention indoor, and it is all around around body of wall and ground, and on rear side of the refrigerator that release magnetic field is maximum, side is towards outdoor, thus reduces and avoid refrigerator magnetic field on the impact of human body and infringement.
5. respectively from the angle analysis of user, housing developer, refrigerator manufacturers and society
For user, refrigerator power saving in wall, refrigerating capacity is large, refrigerator magnetic field misgivings are reduced or remitted, contrast is placed in indoor refrigerator also " many " can go out certain careat, space, and the room rate of the area that " many " go out is toward the price of contact higher than refrigerator itself, cost-effective, the area economized out, space are also practical, should be welcome.
For housing developer, in house desigh construction, external wall of house reserve the body of wall room slightly wider than refrigerator so that and then in finishing wall hole both without the bottleneck in engineering mechanics, also increase the problem of cost and room rate without the great number consumption of very material funds, body of wall room can according to type of house, local climate and vegetable food market situation are reserved, adapt with demand, as villa can reserve the body of wall room of larger split type exist side by side refrigerating box and household freezer, apartment, residential building can reserve the body of wall room of common vertical refrigerator, temperature is warmer, gentle temperature cold in the abundant region of fresh vegetables supply needs a large amount of refrigerating food storage region resident to use the refrigerator reserved body of wall room that varies in size to vary in size, shutoff how many works and material can not be taken yet when wall Vacancy temporarily need not be fitted up even so, housing developer is had every advantage and not a single disadvantage substantially, the bright spot of housing sale will be become.
For refrigerator manufacturers, refrigerator power saving in wall, refrigerating capacity is large but manufacturing cost there is no obvious increase, and the workload that wherein conventional refrigeration technology is born reduces; the available machine times such as compressor shorten; downtime lengthens, and refrigerators last is extended, and market prospects are had an optimistic view of.And refrigerator manufacturers and the housing developer near win-win & mutual benefit of cooperation in wall in refrigerator environment temperature space and wall in refrigerator.
For society, because refrigerator had become the requisite large household appliance of all Modern Families already, use amount is so big, and the social benefit of refrigerator energy-saving environmental protection is also of crucial importance, and in wall, the advantage of refrigerator will be taken seriously and promote.
