Description

Cold water circulation wearable air conditioner

Technical Field

The present invention relates to an air conditioner, and more particularly, to an air conditioner for a human body air conditioner.

Background

When people work or live indoors, a wide variety of air conditioning systems or various air conditioning apparatuses such as: the types and methods of large-scale central air conditioning systems, household central air conditioning systems, room air conditioning systems, and process air conditioning systems of local process equipment are very numerous.

When people need to move in outdoor high-temperature work, particularly in the working process, it is not easy to obtain a certain cool and comfortable feeling, and the work has to be stopped in many cases.

In winter, the heat preservation or comfort of the human body is realized, so that the method is simple, and the requirement is basically met when the warm-keeping clothes are worn; but in summer, even if the minimum of clothes is worn during outdoor work, it still feels very hot. To obtain a cool body feeling, the simplest method is to blow air by a fan, but certain conditions are also required, for example:

1, a power supply is arranged at a working place to transmit power to a fan;

2 the outdoor temperature is not particularly high, i.e. the outdoor wet bulb temperature is lower than the body surface temperature of the human body;

and 3, the air quantity of the fan is enough large.

In addition, the air quantity and the air temperature of the method are difficult to meet the personalized requirements of everyone, namely: under the condition of the same blowing air quantity, people feel comfortable and people feel uncomfortable (of course, a method of one fan for each person and adjustable fan rotating speed can be adopted).

In order to solve the problem of human body air conditioning in outdoor high-temperature environment, one of the earlier proposed and implemented solutions is "ventilated clothing", namely, a ventilation pipeline is manufactured on the clothing, a small fan driven by a storage battery is hung on the clothing, and the fan is started to supply air to a ventilation space in the clothing, so that the ambient air is uniformly supplied to the surface of a human body. Obviously, this approach does not completely solve the "comfort" problem (e.g., when the wet bulb temperature is high, the effect of this approach is not good or even effective), and the garment is blown by air during use to "bulge" and is not attractive nor affects the convenience of work.

Searching for related patent documents, many patent applications related to air conditioning clothing have also been found, for example: the patent with application number 201310376657.3 discloses a temperature adjusting garment, which comprises a hollow garment, a portable air conditioner, a rechargeable battery and the like. This patent is entirely feasible in principle, but also has problems: the total weight of the air conditioner and the battery satisfying the necessary time period is very heavy, and it is also a problem how to effectively reduce the overall cost by increasing the load or labor intensity of the worker seriously.

The application number 201621067939.0 discloses a 'water circulation' cold and warm air conditioning garment, improves a circulation system in the air conditioning garment, solves the problems of large volume and other problems of a 'ventilation' type air conditioning garment by adopting a water circulation mode, and still has the problems of complex refrigeration mode, large weight (because of comprising a refrigeration device) and the like.

There are other technical solutions related to human body air conditioning refrigeration, for example: adopts the technical scheme of a semiconductor refrigeration mode. The main problems with this approach are: the refrigerating device and the storage battery are still heavy, the energy efficiency of semiconductor refrigeration is very low, and the energy consumption is very high, so that the capacity of the storage battery is very high, the weight is increased, and the cost is increased.

In order to solve the problems of heavy weight, high cost, inconvenient use and the like of the existing human body air conditioner in the outdoor high-temperature environment, the invention provides the wearable human body air conditioner which directly uses external ice making equipment as a cold source.

Disclosure of Invention

In order to solve the problems of large volume, heavy weight, inconvenient use, short continuous use time, low refrigeration energy efficiency, insufficient comfort, inconvenient operation and the like of the existing wearable human body air conditioner, the invention provides a wearable human body air conditioner which directly uses external ice making equipment to provide a cold source, which is specifically described as follows:

a wearable air conditioning device comprises two parts, namely a water circulation garment and an ice water circulation device; the water circulation garment is a garment and/or trousers with water circulation hoses arranged on the inner side of the garment; the hose is a continuous pipeline system and is provided with a general water inlet and a general water outlet. The ice water circulation device comprises a power supply device, a water pump, an ice water box and other parts, wherein the ice water box is a hollow container in which small ice cubes or crushed ice can be placed; the water pump is directly driven by the power supply device, the inlet of the water pump is connected to the outlet of the ice water box through a hose, the outlet of the water pump is connected with a section of hose, one end of the hose is connected with the water pump, and the other end of the hose is used as the water outlet of the whole ice water circulation device and is connected to the water inlet of the water circulation garment in use; the inlet of the ice water box is also connected with a hose, one end of the hose is connected with the ice box, and the other end of the hose is used as a water inlet of the whole ice water circulation device and is connected to a water outlet of the water circulation clothing when in use.

Since the wearable air conditioner does not have a refrigerating device, the required cooling capacity is provided by external equipment, and the wearable air conditioner has the advantages that: the weight and the volume of the refrigeration device which is attached to the wearable air conditioner device can be effectively reduced. This is a major difference from the current prior art (e.g., the techniques disclosed in application Ser. No. 201621067939.0 and 202211019620.0).

Optionally, the wearable air conditioner is further provided with an ice making box, wherein the ice making box is a closed container with a thin wall and the external dimension of the ice making box is just matched with the internal dimension of the ice water box after the ice making box is filled with ice.

The technical scheme has the advantage of fully utilizing the inner space of the ice water box, namely: the ice water box with the same volume can hold ice blocks with larger mass (compared with the use of crushed ice and ice blocks), so that the cooling time of the ice water circulation device is longer.

Further, a water flow regulator is arranged on the water outlet pipeline of the water pump of the ice water circulation device.

The water flow rate adjusting device can conveniently control the water supply flow rate of the water pump, thereby realizing the control of the cold supply quantity and enabling the cold supply quantity to adapt to the requirement of the human body on the heat load.

Optionally, a bypass pipe and a bypass flow regulating valve are arranged between the water inlet pipe and the water outlet pipe of the ice water circulation device.

The water temperature fed into the water circulation clothing can be controlled by adjusting the water flow in the bypass pipe by utilizing the pipeline and the valve, and the adjustment of the cooling capacity or the adjustment of the comfort of a human body can be realized; the water temperature adjusting mode can further improve the human body feeling comfort level, and can prevent water with lower temperature from entering the garment and prevent the human body from feeling too low temperature.

Further, the flow regulating device adopts a transfusion tube regulator.

Obviously, the flow regulating mode has extremely low cost and good use convenience.

Further, the ice water box has an ice capacity of 1kg to 5kg.

When the ice capacity of the ice water box of the wearable air conditioner is in the range, the ice water box has good application, can meet the needs of most people, and has more flexibility.

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 will be apparent that the described embodiments are only some, but not all, embodiments of the invention.

All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.

In the description of the present invention, it should also be noted that, unless explicitly specified and limited otherwise, the terms "connected," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.

The following describes embodiments of the invention in terms of various figures, including flowcharts, block diagrams, and the like.

As shown in fig. 1 and 2, the wearable air conditioner mainly comprises two parts of a water circulation garment 100 and an ice water circulation device 200, wherein the two parts are connected by a pipe section 243 (i.e. a water outlet pipe) and a pipe section 244 (i.e. a water inlet pipe) of the ice water circulation device 200 (connected to a water inlet 101 and a water outlet 102 of the water circulation garment respectively).

After the water circulation garment 100 is connected with the ice water circulation device 200, the water circulation garment 100 can be cooled by cold water circulation, so that an air conditioning effect on a human body is achieved, and the water circulation garment is described in detail below.

Ice water circulation device 200 is secured in place on the back or other suitable location of water circulation garment 100 using a lap fastening device or a pocket (not shown).

The water circulation garment 100 consists of an outer layer, an inner layer and a serpentine water pipe arranged in the two layers, wherein the outer layer is made of cloth with good heat insulation performance, and the inner layer is made of thinner cloth with relatively good heat conduction performance; when water with lower temperature is filled in the middle serpentine water pipe, the temperature of the inner layer is reduced, and an air layer with lower temperature is established between the garment and the human body, so that the human body feels cool, and the comfort of the human body is improved; the good heat preservation performance of the outer layer can reduce the loss of cold in the serpentine coil, so that the cold can serve the human body as much as possible. Since cold water will circulate in the serpentine, to reduce the overall weight, the serpentine uses plastic tubes of smaller diameter and thinner wall thickness, such as: a small transfusion hose for transfusion in hospitals.

The hoses in the water circulation garment can be connected in series and in parallel, and finally combined into a total garment water inlet 101 and a total garment water outlet 102 so as to be connected with the ice water circulation device 200; in the pipeline serial association process, the total resistance of the inlet and the outlet is also used for adapting to the water pump lift data, and in addition, the heat absorption capacity of the surface of the water circulation clothing is also used for adapting to the heat dissipation capacity of a human body.

Ice cubes are placed in the ice water circulation device 200, and a necessary small amount of water is filled in the ice water circulation device, so that the water circulation can be operated after the water pump 220 is started, and cold water enters the water circulation garment.

Since ice is placed in the ice water circulation device 200, at the beginning, the ice water circulation device 200 is filled with water in a mixed state of ice water at a temperature of 0 ℃; when the water pump 220 circulates, water at 0 ℃ is sent into the serpentine heat exchange coil in the water circulation clothing, and then the cold energy is released, so that the human body feels cool. When the water flow is large, the serpentine heat exchange coil can release more cold energy, so that the human body feels that the temperature is too low, at this time, the water flow can be reduced through a regulating device (to be further described later) on the ice water circulation device 200, otherwise, the water flow is increased, and finally, the temperature of the inner layer of the water circulation garment 100 is stabilized at a temperature which is comfortable for the human body.

The cold water continuously circulates between the water circulation garment 100 and the ice water circulation device 200 to continuously release the cold energy, meanwhile, the ice in the ice water circulation device 200 is gradually melted, and finally, the ice is completely melted, then, the water temperature is gradually increased, when the water temperature is increased to about 20 ℃, the cold energy in the cold water can not meet the requirement of a human body on the cold energy in general, and at the moment, the ice needs to be added again. Only the cover of the ice water box 230 is opened, water in the ice water box 230 is poured or discharged, ice cubes are filled and discharged, and then the human body can be cooled normally again.

Since the ice water circulation device 200 itself cannot make ice, an additional refrigerating apparatus is required to make ice. Obviously, the ice water circulation device 200 is not so bulky and therefore is only suitable for small ice cubes, such as crushed ice.

The crushed ice has wide sources, is purchased by a certain amount of crushed ice when being used in a special ice making factory, and can be purchased in a supermarket. Of course, if it is often necessary to use the wearable air conditioner, particularly if there are a large number of people who are simultaneously using the wearable air conditioner (for example, a construction site in summer), or if the possibility of reducing the use cost is comparatively high, an appropriate ice making device can be purchased and ice can be made in bulk at the use site.

In a word, the ice is not difficult to obtain, so the wearable air conditioner has the characteristic of convenient use.

What needs to be stated is: it will be said that, by peeling off the refrigerating device, the wearable air conditioner can reduce the weight and volume of the device, but increase the weight and volume of ice cubes, and is not able to achieve the intended purpose?

The following description is briefly made:

1 the weight of the compressor of the compression refrigeration apparatus, which can provide about 100W of cold required by the human body, reaches about 5kg, which does not include other components (such as evaporator, condenser, heat exchange fan, etc.) required. Obviously, the volume of the kit of parts assembled together will not be small.

2, by adopting a 'semiconductor refrigeration' technical scheme, the weight of the refrigeration device is smaller than that of the compression refrigeration device, but the total weight is still not light, and the volume is not small (because a larger radiator is needed); in addition to the need to configure a power supply with greater power, the weight and size are increased. This is not yet calculated, because the semiconductor refrigeration technology has another major disadvantage that the refrigeration efficiency of the semiconductor refrigeration technology is too low, about only about 0.3, and the operation power consumption is about 300W or more to meet the requirement of about 100W of human body. This requires a larger capacity battery to accommodate, which would result in a significant amount of infeasibility (in terms of weight, cost, volume, etc.).

Next, embodiments of the ice water circulation device will be described in detail.

As shown in fig. 3, the ice water circulation device 200 includes several components including a power supply device 210, a water pump 220, an ice water box 230, and a pipeline 240, and the connection relationship between them is: the pipe section 246 is used for connecting the water outlet port 234 of the ice water box with the inlet of the water pump 220, the pipe section 242 is connected from the outlet of the water pump 220, is directly connected to the outside of the whole ice water circulation device 200 and is kept for a certain length so as to be convenient for docking with the water circulation garment 100; the pipe section 243 has one end connected to the water inlet 235 of the ice water box 230 and the other end connected to the outside of the ice water circulation device 200, and also has a certain length so as to be conveniently docked with the water circulation garment 100.

The water pump 220 is a miniature direct-current water pump driven by a USB power supply, and the water pump has small consumption power because the water flow is small and the total length of a pipeline is not long; the water pump has small volume, easy acquisition and low cost.

The power supply device 210 mainly comprises a storage battery 211, the storage battery is a mobile phone charger, the storage battery 211 is connected with the water pump 220 through a power line 212, and obviously, the power line is preferably a USB line; a water pump rotation speed adjusting device 214 can be installed between the storage battery 211 and the water pump 220 to adjust the rotation speed of the water pump 220, thereby adjusting the water flow and realizing the adjustment of the cooling capacity.

In particular, the "cooling capacity" of the ice water circulation device 200 may be adjusted by providing a clip-on adjusting device on the pipe section 242 to adjust the flow, and particularly by using a perfusion tube adjuster 241, which exactly meets the needs of the scenario, besides the method of the water pump rotation speed adjusting device 214 described herein, the method also has a plurality of beneficial characteristics of simplicity, convenience, easy acquisition, low cost, and the like.

With the adjustment method of the water pump rotation speed adjusting device 214 and the infusion tube adjuster 241, since the water supply temperature of the water pump cannot be adjusted, another adjustment method is recommended in this embodiment, that is, a bypass pipe 244 is installed between the pipe sections 242 and 243, and a bypass flow rate adjusting valve 245 is installed thereon, so that the potential problem can be solved. Bypass valve 245 may also employ a tubing regulator.

The operation of the water pump 220 is generally controlled by a switch, and a power switch 213 of a storage battery (charger) may be used.

Fig. 4 provides a mechanical structure diagram of a more specific ice water circulation device, which comprises a front view, a left view, a top view, an A-A face view and an isometric view. This embodiment employs a rectangular parallelepiped-shaped ice-water box 230 and integrates most of the components shown in fig. 3 into the figure (except for tube segment 242 and tube segments 243, 244 and associated conditioning devices). A complete ice water circulation device 220 can be manufactured by referring to the figure.

Fig. 4 can be more clearly understood with reference to fig. 3. But here it is further to be supplemented as follows:

in fig. 4, the ice water 233 has at least 2 states during use, namely: there are two states of ice and no ice. After ice cubes are added into the ice water box 230, the ice is completely dissolved into water along with the release of the cold energy, and finally, the water temperature is increased to 20 ℃ or even higher, at this time, the cold energy cannot meet the needs of a human body due to the higher water temperature, so that the water in the ice water box is required to be poured out (or released), and the ice is added again.

Accordingly, the present invention also provides another embodiment: an ice water pack was manufactured according to the physical size of ice water 233. The ice-water bag is similar in shape to ice-water box 230, but slightly smaller in size to facilitate removal or placement. The ice water bag has the structure that: the shell is of a closed structure and is made of plastic with lower temperature resistance, the thickness is as thin as possible, and clear water is filled in the shell (the volume expansion allowance in the process of changing water into ice is reserved).

Before the ice water bag is used, the ice water bag is frozen by a refrigerator or other refrigeration equipment, so that all water in the ice water bag is changed into ice, and then the frozen ice water bag is placed into the ice water box 230 for use; after the use is finished, the ice water bag is put into the refrigerator again for frozen ice for the next use.

By adopting the method, the processes of adding ice and pouring water are not needed, and the use convenience is improved. However, it is also possible to further promote: that is, each set of ice water circulation device 220 can be provided with 2 to a plurality of ice water bags, so that after the cold energy of one ice water bag is used, the ice water bag can be taken out to be replaced by another ice water bag immediately.

If the product is applied to a construction site or a workshop, a batch of ice water bags can be configured, and the ice water bags are frozen in batches by utilizing a large refrigerator (such as a refrigeration house) and then are put on a use site for replacement by workers at any time.

The ice water bag not only improves the speed of supplementing cold energy, but also avoids the trouble of pouring water, and more importantly: the volumetric efficiency of the ice water cartridge 230 is also improved, namely: in the same ice water box, the total mass of the fillable crushed ice is smaller than the mass of the ice in the ice water bag, namely: the cooling capacity or cooling time length of the ice water bag is longer than that of the crushed ice.

In addition, in fig. 4, another detail to be noted is also expressed: namely: a support point 236 for the ice water pack is formed at the lower part of the ice water box, so that the water flow is smoother and organized.

In order to further guide the implementation of the technical scheme of the invention, the method for calculating the volume of the ice water box and some considerations are as follows:

the average heat dissipation of the human body can be calculated as 100W, so the total heat dissipation of one person for 2 hours is about 200 w.h. In the process of melting 1kg of ice into water and then heating to 20 ℃, the heat required to be absorbed is 116W.h, so that the cooling requirement of 1 person for 2 hours is ensured, and the required ice amount is: 200/116= 1.724 (kg).

Because the heat dissipation capacity of the human body cannot be completely released through the wearable air conditioner, a considerable part of the heat dissipation capacity can be directly dissipated into the atmosphere through other exposed parts of the human body, and the cold energy requirement on the ice water circulation device is reduced. The inventor shows that the configuration of 1.5kg of ice can meet the cooling capacity requirement of 2 hours in most cases through some calculation and analysis. After 2 hours of work, the staff can take a moderate rest or adjust the ice-changing process.

If the ice water container 230 has a capacity of 1.5kg for ice, and the total weight of the ice water circulation device components is about 2.5kg, the ice water container will not be burdened with staff, so the ice capacity data can be used as a main design data; obviously, the possibility of reducing the ice capacity to about 1kg is also feasible, and is suitable for people with excessive weight requirements (of course, the number of times of adding ice or changing ice needs to be increased), such as females; in addition, in some occasions, when the use time is required to be longer (at the moment, important requirements can be reduced), the volume of the ice water box can be larger, for example, the ice water box is increased to 5kg, and the ice water box has certain feasibility or necessity. In fact, the volume can be directly increased so that more ice can be accommodated, and for people dislike a weight too heavy, less ice can be accommodated, that is, each person can hold more or less ice according to own preference. According to the calculation, the ice containing amount is in the range of 1 to 5kg, and the hobbies or demands of most people can be met.

The structure of fig. 4 provides a rectangular ice water box, and it should be noted that: this does not limit the scope of the invention. In practice, the ice water box does not have to be made into a shape, for example, a cylindrical shape, an elliptic cylindrical shape, etc., and of course, other shapes can be made, which are all within the protection scope of the present patent.
