Description

Four seasons constant temperature bed

A kind of constant temperature bed, the four seasons constant temperature bed of suitable daily life and health care.

Number of patent application is that 86210398 " changes in temperature constant temperature bed " is current comparatively advanced and high-grade constant temperature bed, and it has used the refrigeration of electronics heap, pyrogenicity, and has realized that temperature is adjustable, four seasons constant temperature by control circuit.But it is subjected to the restriction of electronics heap power, and temperature controlling range is less, narrow application range.

Task of the present utility model provides a kind of improved four seasons constant temperature bed, reaches to enlarge the purpose that refrigeration, pyrogenicity scope can adapt to various functional requirements.

The utility model is achieved in that mattress divides into thermostatic chamber, with far infrared electronic component heating heating, with electronics heap refrigeration cooling.Its circuit also comprises timing circuit, on-off circuit, lamp circuit, temperature-adjusting circuit, but its temperature-adjusting circuit is to show measuring and controlling temp definite value table and control electron cooling heap and the work of far infrared electronic component by the driver and the changes in temperature switching relay of its control by numeral.

The utility model constant temperature timing arbitrarily, temperature range is bigger, goes for life with bed, medical treatment or Bed for rescuing paitent, goes for cold district and tropical climate.

Details of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is the utility model steel spring bed structure schematic diagram.

Fig. 2 is the utility model cushion bed structure schematic diagram.

Fig. 3 is the utility model electrical schematic diagram.

Fig. 4 is the utility model control panel face figure.

With reference to the accompanying drawings: mattress 4 of the present utility model can adopt steel spring formula 4a or Simmons soft cushion 4b according to different purposes, divides into thermostatic chamber 5 at mattress 4, settles electron cooling heap 6(or mechanical refrigeration device on the base plate of thermostatic chamber 5) and far infrared electronic component 7.Ground light 8 is established in lathe bed 3 both sides, and the head of a bed 1 is established control panel 2, and time switch Q is arranged on the control panel 2, on-off switch K ₁～K ₁₀, signal lamp D ₁, D ₂, illuminating lamp tube XD ₁, and regularly show thermometric definite value table KDX-2 with quartz clock KXDJ-2 and numeral ₁The thermostatic chamber wall has heat-insulation layer 9.

Circuit of the present utility model is made up of timing circuit A, on-off circuit B, refrigeration, pyrogenicity control circuit C and lamp circuit D.Wherein used element and operation principle are identical with 86210398 among timing circuit A, on-off circuit B and the lamp circuit D, repeat no more.It mainly improves: in its refrigeration, the pyrogenicity temperature-adjusting circuit, comprised transformer BK ₁And the voltage-stablizer QL in its circuit of output terminal ₁, capacitor C ₁And resistance R D ₂, power supply is introduced electron cooling heap WCAO and infrared ray electric sub-element YHW behind transformer and voltage regulation filtering.Thermistor Rt ₁Input introduce numeral and show measuring and controlling temp definite value table KDX-2 ₁, KDX-2 ₁Control end be connected into driver KDX-2 ₂, hold in addition and relay J ₁Join.Driver KDX-2 ₂Meet power switch K ₃With the changes in temperature K switch ₁And transformer BK ₁, and connection, control relay J ₁

Its temperature control principle is: establish 15 ℃ of room temperatures, need the control bed temperature between 30 ℃～35 ℃, adjust KDX-2 by this requirement ₁, with K ₁Switch disconnects, then J ₁No power, J ₁The contact maintains the original state.Connect K ₃Power switch, then KDX-2 ₁Accept Rt ₁The temperature information that transmits as below 30 ℃, then orders about KDX-2 ₂Connection work.Make transformer BX ₁Work, after step-down, electric current is through YHW and J ₁Normally-closed contact constitute secondary circuit, YHW far infrared electronic component begins heat temperature raising.When the thermostatic chamber temperature is raised to 35 ℃, by Rt ₁Transmit signal and give KDX-2 ₁Output signal drives KDX-2 ₂Deenergization is stopped power supply.At this moment begin cooling, when dropping to 30 ℃ down in limited time, Rt ₁Input signal makes KDX-2 ₁KDX-2 is ordered about in work again ₂Connect, so go round and begin again, maintain the temperature between 30 ℃～35 ℃, realize warm thermostatic control

If 40 ℃ of room temperatures, and require bed temperature between 30 ℃～35 ℃, KDX-2 ₁Still definite value is at 35 ℃ of ceiling temperatures, 30 ℃ of lower limits, K ₃Connect power supply, Rt ₁Transmit 40 ℃ of signals, KDX-2 ₁Output signal, K ₁Connect J ₁Adhesive, J ₁Each contact paraphase makes KDX-2 ₁Output signal is anti-phase, drives KDX-2 ₂, BK ₁Electricity is arranged, but the YHW loop is obstructed, and the work of WCAO electron cooling heap, temperature is descended, when 30 ℃ of lower limits, KDX-2 ₂Deenergization, WCAO quits work, and thermostatic chamber heats up, and so circulation realizes cold thermostatic control.

Combination hub KS is arranged in control circuit, can connect the micromachine refrigeration plant, replace the refrigeration of electronics heap.The bed that middle low temperature uses down is with the refrigeration of electronics heap; When needing low temperature, then the micromachine refrigeration plant can be installed.

The utility model scope of application is wide, can be used for bed for civilian use, physiotherapy couch, emergency bed. Use 220V voltage, bed for civilian use power 120W, warm constant temperature can be by normal temperature to 40 ℃, and cold constant temperature can be by 40 ℃ to 20 ℃; Physiotherapy couch power 200W, warm constant temperature can be by 10 ℃ to 45 ℃, and cold constant temperature is by 40 ℃ to 10 ℃; Emergency bed power 300W, warm constant temperature is by 5 ℃ to 40 ℃, and cold constant temperature can be by 40 ℃ to 5 ℃.
